DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
Next, embodiments of the present invention will be
25 described with reference to the drawings. FIG. 1 is a plan
view illustrating a bobbin supplying device 10 according
to one embodiment of the present invention along with a tray
feeding path 110 and an automatic winder 100. FIG. 2 is
a perspective view illustrating an overall configuration
30 of the bobbin supplying device 10.
In the following description, “upstream” and
5 / 56
“downstream” refer to upstream and downstream with respect
to a feeding direction of a yarn supplying bobbin 3 and a
feeding tray (feeding member) 2.
A bobbin supplying device (bobbin supplying system)
10 illustrated in FIG. 1 supplies, to the automatic wi5 nder
100, the yarn supplying bobbin 3 in which a yarn is wound
around a core tube (winding tube) 4.
The automatic winder 100 includes a plurality of
winder units 101 arranged in line. Each of the winder units
10 101 unwinds a yarn from the supplied yarn supplying bobbin
3, and forms a package in which a predetermined amount of
yarn is wound.
As illustrated in FIG. 1, the tray feeding path 110
includes a yarn supplying bobbin introducing path 111, a
15 yarn supplying bobbin feeding path 112, a core tube feeding
path 113, and a return bobbin feeding path 114.
A bobbin supplying device 10, to be described later,
adapted to supply the yarn supplying bobbin 3 is arranged
on the yarn supplying bobbin introducing path 111. The yarn
20 supplying bobbin introducing path 111 is configured to feed
the feeding tray 2, on which the yarn supplying bobbin 3
is set by the bobbin supplying device 10, to the yarn
supplying bobbin feeding path 112.
A yarn supplying bobbin lead-out device 115 is
25 arranged between the yarn supplying bobbin introducing
path 111 and the yarn supplying bobbin feeding path 112.
The yarn supplying bobbin lead-out device 115 performs a
process of dissociating and leading out a yarn end from a
surface (yarn layer) of the yarn supplying bobbin 3
30 supplied from the yarn supplying bobbin introducing path
111, winding the lead-out yarn end around a top portion of
6 / 56
the core tube 4 (side opposite to the side to be inserted
to the feeding tray 2) and inserting the yarn to a top hole
(hole on the top portion side) of the core tube 4.
The yarn supplying bobbin 3 lead-out processed by the
yarn supplying bobbin lead-out device 115 is supplied 5 ed to
each winder unit 101 of the automatic winder 100 through
the yarn supplying bobbin feeding path 112. In each of the
winder unit 101, the compressed air is blown from the bottom
portion of the supplied yarn supplying bobbin 3 to blow away
10 the yarn end processed by the yarn supplying bobbin
lead-out device 115, thus pulling out and winding the yarn
end from the yarn supplying bobbin 3. The yarn winding
operation performed by the winder unit 101 is known, and
thus the description thereof will be omitted.
15 The core tube feeding path 113 is configured to feed
the yarn supplying bobbin (i.e., core tube 4) in which the
yarn is unwound by each winder unit 101 and discharged, to
a bobbin extracting device 116 arranged on the downstream
side.
20 The core tube 4 is an elongate cylindrical member and
is formed such that the diameter linearly reduces from the
bottom portion (large diameter end) 4a toward the top
portion (small diameter end) 4b. In other words, the
diameter of the bottom portion 4a of the core tube 4 is
25 greater than the diameter of the top portion 4b. The bottom
portion 4a of the core tube 4 is inserted to a peg of the
feeding tray 2, so that the yarn supplying bobbin 3 is set
on the feeding tray 2 and fed with the feeding tray 2.
The bobbin extracting device 116 is configured to
30 extract and collect the core tube 4 from the feeding tray
2 set with the core tube 4. As illustrated in FIG. 1, the
7 / 56
feeding tray 2 from which the core tube 4 is extracted by
the bobbin extracting device 116 is supplied to the bobbin
supplying device 10.
As illustrated in FIG. 1, the return bobbin feeding
path 114 is arranged between the yarn 5 supplying bobbin
feeding path 112 and the core tube feeding path 113. The
return bobbin feeding path 114 is configured to re-process
the yarn supplying bobbin 3 that failed in the lead-out
process by the yarn supplying bobbin lead-out device 115
10 and the core tube 4 fed to the bobbin extracting device 116
for some reasons.
As illustrated in FIG. 2, the bobbin supplying device
10 includes a bobbin input device 11, a part feeder (bobbin
individualizing device) 12, a bobbin sorting device (yarn
15 supplying bobbin distributing device) 5, a pair of bobbin
direction aligning device (yarn supplying bobbin direction
changing device) 6, a pair of bobbin chutes (bobbin
mounting device) 13, and a control section 90.
The bobbin input device 11 is schematically
20 illustrated in FIG. 2, where the bobbin input device 11 is
configured to input the yarn supplying bobbin 3
manufactured by a fine spinning machine (not illustrated)
to a central bottom portion of the part feeder 12 using,
for example, a conveyor. The configuration is not limited
25 thereto, and the bobbin input device can be configured to
convey the yarn supplying bobbin 3 to the part feeder 12
while being in a container and the like (not illustrated),
and input the yarn supplying bobbin to the part feeder 12.
In the part feeder 12, a spiral-shaped passage 12a
30 is continuously arranged on the inner peripheral surface
from the center portion to a feed-out port 12b which is on
8 / 56
the outer periphery. A drive device adapted to vibrate the
part feeder 12 is arranged at a lower part of the part feeder
12. The yarn supplying bobbin 3 input by the bobbin input
device 11 is aligned one at a time and conveyed toward the
feed-out port 12b while raising the spiral-5 shaped passage
by the vibration of the part feeder 12.
A bobbin feed conveyor (bobbin feeding device) 14 is
arranged between the part feeder 12 and the bobbin sorting
device 5. The bobbin feed conveyor 14 is configured to
10 continue to the feed-out port 12b of the part feeder 12 to
extend the spiral-shaped passage 12a in proximity to the
feed-out port 12b. Thus, the yarn supplying bobbin 3 fed
out from the feed-out port 12b is fed as is by the bobbin
feed conveyor 14.
15 The bobbin feed conveyor 14 has a width slightly
wider than the thickness of the yarn supplying bobbin 3
(thickness of the portion where the yarn is wound). The
bobbin feed conveyor 14 is configured to feed the yarn
supplying bobbin 3 in a substantially horizontal
20 orientation so that the longitudinal direction of the core
tube 4 of the yarn supplying bobbin 3 (hereinafter
sometimes simply referred to as a longitudinal direction
of the yarn supplying bobbin 3) matches the feeding
direction in the bobbin feed conveyor 14.
25 The bobbin sorting device 5 is arranged downstream
of the bobbin feed conveyor 14. The bobbin sorting device
5 includes at the upper part thereof an elongate bobbin
passage 16 where the yarn supplying bobbin 3 fed from the
bobbin feed conveyor 14 passes. The bobbin sorting device
30 5 includes five rotation guide plates 27 that are aligned
with an equal angular interval and that can integrally
9 / 56
rotate. The rotation guide plate 27 configures a part of
a rotation guiding section (bobbin distributing section)
17 adapted to guide the bobbin by rotating. The bobbin
sorting device 5 rotates the rotation guiding section 17
in a forward direction or a reverse direction to sort 5 rt the
yarn supplying bobbin 3 to the side on one side or the other
side of the bobbin passage 16 path.
Two supplying paths 8 adapted to supply the yarn
supplying bobbin 3 in a distributed manner are arranged on
10 the downstream of the bobbin sorting device 5. A bobbin
direction aligning device 6, a discharge guiding member 15,
and a bobbin chute 13 are arranged in each of the supplying
paths 8.
The bobbin direction aligning device 6 is arranged
15 on a lower side of both sides with respect to the
longitudinal direction of the bobbin passage 16 arranged
in the bobbin sorting device 5.
Each bobbin direction aligning device 6 includes a
pair of core tube guiding paths (winding tube guiding path)
20 63 adapted to guide both ends (bottom portion 4a or top
portion 4b, which are exposed portions of the core tube 4)
of the yarn supplying bobbin 3 input in a horizontal
orientation from the bobbin sorting device 5. Of the pair
of core tube guiding paths 63, the bottom portion 4a of the
25 yarn supplying bobbin 3 is fed to one path and the top
portion 4b is fed to the other path. Since in which
orientation the yarn supplying bobbin 3 is supplied with
respect to the bobbin direction aligning device 6 is not
constant, which of the bottom portion 4a or the top portion
30 4b is fed to each core tube guiding path 63 is not known.
Each core tube guiding path 63 receives the bottom
10 / 56
portion 4a and the top portion 4b of the yarn supplying
bobbin 3 at a predetermined location. When the lower side
of the location where the bottom portion 4a is received is
opened, the yarn supplying bobbin 3 is dropped from the
bottom portion 4a side. In this manner, the 5 bobbin
direction aligning device 6 can supply the yarn supplying
bobbin 3 downstream with the direction of the yarn
supplying bobbin 3 aligned so that the bottom portion 4a
is on the lower side.
10 The bobbin chute 13 is arranged on the lower side of
the bobbin direction aligning device 6. The bobbin chute
13 sets the yarn supplying bobbin 3 supplied from the bobbin
direction aligning device 6 so that the core tube 4 of the
yarn supplying bobbin 3 is inserted to the peg of the
15 feeding tray 2 for feeding the yarn supplying bobbin 3. The
yarn supplying bobbin 3 mounted on the feeding tray 2 is
then fed to the plurality of winder units 101 in the
automatic winder 100 through the yarn supplying bobbin
introducing path 111 and the yarn supplying bobbin feeding
20 path 112 illustrated in FIG. 1.
A hollow discharge guiding member 15 adapted to guide
the yarn supplying bobbin 3 in which the direction is
aligned by the bobbin direction aligning device 6 is
arranged between the bobbin direction aligning device 6 and
25 the bobbin chute 13. Two openings (first opening 15a and
second opening 15b) having different size are formed in the
discharge guiding member 15. The first opening 15a is
formed relatively large and is arranged on the upper
surface of the discharge guiding member 15. The second
30 opening 15b is formed relatively small and is arranged on
the lower surface of the discharge guiding member 15. The
11 / 56
first opening 15a is located immediately on the lower side
of the bobbin direction aligning device 6, and the second
opening 15b is located immediately on the upper side of the
bobbin chute 13. According to such a configuration, the
discharge guiding member 15 can reliably guide the 5 yarn
supplying bobbin 3 dropped from the bobbin direction
aligning device 6 to the bobbin chute 13.
Next, with reference to FIGS. 3 and 4, the bobbin
sorting device 5 will be described in detail. FIG. 3 is
10 a perspective view illustrating a configuration of the
bobbin sorting device 5. FIG. 4 is a cross-sectional view
taken along line A-A of FIG. 3.
The bobbin sorting device 5 includes a pair of leg
portions 21, a pair of supporting shafts (shaft member) 22,
15 a passage supporting plate 23, a bobbin introducing
conveyor 24, a conveyor drive motor (conveyor drive source)
25, a pair of rotation supporting plates 26, five rotation
guide plates (push-out member) 27, a regulation plate
(bobbin regulating member) 28, a rotation motor 29, a cam
20 member 30, and a phase holding arm 31.
The rotation guiding section 17 adapted to sort the
yarn supplying bobbin 3 by rotating in the bobbin sorting
device 5 is configured to include a pair of rotation
supporting plates 26, five rotation guide plates 27, and
25 the regulation plate 28.
The pair of leg portions 21 is arranged to face each
other with an appropriate interval. The rotation guiding
section 17, the passage supporting plate 23, the bobbin
introducing conveyor 24, the conveyor drive motor 25, and
30 the like are arranged between the pair of leg portions 21.
The pair of supporting shafts 22 is fixed to the upper
12 / 56
part of each leg portion 21. The pair of supporting shafts
22 is arranged so as to match the axis lines. The pair of
supporting shafts 22 projects out to face each other and
each rotation supporting plate 26 is rotatably supported
at the projecting portion. The axis line of the 5 supporting
shaft 22 matches the rotational axis line of the rotation
guiding section 17. As illustrated in FIG. 3, the
supporting shaft 22 includes a shaft hole 22a in a
pass-through form, and as a result, the supporting shaft
10 22 is formed into a hollow shape (cylindrical shape with
both axial ends opened).
The passage supporting plate 23 is configured as an
elongate rectangular plate-shaped member in a direction
parallel to the axis line of the rotation guiding section
15 17, where the thickness direction thereof is arranged to
be directed in the horizontal direction. As illustrated
in FIG. 4, the passage supporting plate 23 is arranged at
a position deviated to one side in the horizontal direction
from the rotational axis line in a space surrounded by the
20 rotation guide plate 27 (i.e., internal space of
cylindrical rotational trajectory drawn by the rotation
guide plate 27). Thus, a space for installing the bobbin
introducing conveyor 24 and the conveyor drive motor 25 can
be ensured. The longitudinal direction of the passage
25 supporting plate 23 formed into an elongate rectangular
shape is arranged parallel to the rotational axis line of
the rotation guiding section 17. Both ends in the
longitudinal direction of the passage supporting plate 23
are respectively fixed to the projecting portions of the
30 pair of supporting shafts 22 by way of a bracket (not
illustrated).
13 / 56
The bobbin introducing conveyor 24 is attached to the
surface on one side of the passage supporting plate 23. The
bobbin introducing conveyor 24 includes a drive roller 51,
a driven roller 52, a path regulating roller 53, and a feed
belt 5 (conveyor belt) 54.
The drive roller 51, the driven roller 52, and the
path regulating roller 53 are all rotatably supported by
the surface on one side of the passage supporting plate 23.
The feed belt 54 is formed into an endless form, and is wound
10 across the drive roller 51 and the driven roller 52.
In the passage supporting plate 23, the conveyor
drive motor 25 is attached to the surface on the same side
as the side where the bobbin introducing conveyor 24 is
arranged. The conveyor drive motor 25 is arranged on the
15 lower side of the bobbin introducing conveyor 24.
The output shaft of the conveyor drive motor 25
passes through and projects out from the passage supporting
plate 23. The shaft of the drive roller 51 also passes
through and projects out from the passage supporting plate
20 23. The output shaft of the conveyor drive motor 25 and
the shaft of the drive roller 51 are coupled by a
transmission belt 55. The drive force of the conveyor drive
motor 25 can be transmitted to the drive roller 51 to drive
the bobbin introducing conveyor 24.
25 The feed belt 54 forms an elongate horizontal feeding
surface between the drive roller 51 and the driven roller
52. The feeding surface configures a road surface of the
bobbin passage 16 through which the yarn supplying bobbin
3 passes. The bobbin passage 16 is arranged to continue
30 to the bobbin feed conveyor 14. With the drive of the bobbin
introducing conveyor 24, the yarn supplying bobbin 3 can
14 / 56
be passed in a horizontal orientation through the bobbin
passage 16 with the longitudinal direction thereof
coincided with the longitudinal direction of the bobbin
passage 16.
The diameter of the driven roller 52 is formed to 5 be
smaller than that of the drive roller 51. The path
regulating roller 53 guides the portion on the lower side
of the path of the feed belt 54 and regulates the
circulating path of the feed belt 54 so as to be narrowed
10 in a height direction. The conveyor drive motor 25 is
arranged on the lower side of the portion where the path
is narrowed in the height direction. The bobbin
introducing conveyor 24 and the conveyor drive motor 25 can
be arranged without interfering with each other (see FIG.
15 4) in the internal space of the cylindrical rotational
trajectory drawn by the rotation guide plate 27, to be
described later.
The rotation supporting plate 26 arranged as a pair
each includes a circular flange portion 57, and five arm
20 portions 58 that project out in the radial direction from
the flange portion 57. A shaft hole (not illustrated) is
formed at the center portion of the flange portion 57, and
the supporting shaft 22 is inserted to the shaft hole to
rotatably support the rotation supporting plate 26. Five
25 arm portions 58 are formed to have equal length one another,
and are all integrally formed with the flange portion 57.
The arm portions 58 are arranged at equal intervals (i.e.,
interval of 72°) in the circumferential direction.
The rotation guide plate 27 is configured as an
30 elongate plate-shaped member having a constant thickness.
One end of the rotation guide plate 27 in the longitudinal
15 / 56
direction is fixed to the distal end of the arm portion 58
of the rotation supporting plate 26 on one side, and the
other end of the rotation guide plate 27 in the longitudinal
direction is fixed to the distal end of the arm portion 58
5 of the rotation supporting plate 26 on the other side.
A surface (hereinafter sometimes referred to as a
push-out surface 27a) on both sides in the thickness
direction of the rotation guide plate 27 is configured to
make contact with the yarn supplying bobbin 3 and to push
10 the yarn supplying bobbin 3 to the side of the bobbin
passage 16. Each rotation guide plate 27 (push-out surface
27a) has substantially the same length as the bobbin
passage 16, and thus the elongate yarn supplying bobbin 3
located in the bobbin passage 16 can be suitably pushed out
15 by the rotation guide plate 27.
Each rotation guide plate 27 is arranged so that the
longitudinal direction becomes parallel to the rotational
axis line of the rotation guiding section 17. The five
rotation guide plates 27 are fixed to the arm portion 58
20 of the rotation supporting plate 26, as described above,
and thus are aligned with an equal interval (i.e., interval
of 72°) in the circumferential direction along a virtual
circle having the rotational axis line of the rotation
guiding section 17, which is an axis parallel to the
25 longitudinal direction of the bobbin passage 16 (feeding
direction of bobbin introducing conveyor 24), as the center.
The rotation guide plate 27 is arranged so that the
thickness direction thereof lies along the circumferential
direction of the virtual circle. Thus, the rotation guide
30 plate 27 is radially arranged with the center of the virtual
circle (rotational axis line of rotation guiding section
16 / 56
17) as the center. Two push-out surfaces 27a of the
rotation guide plate 27 are both directed in a direction
orthogonal to the virtual circle.
The five rotation guide plates 27 are attached to the
rotation supporting plate 26 rotatably supported 5 by the
supporting shaft 22. Therefore, the five rotation guide
plates 27 can be integrally rotated along the virtual
circle with the axis line of the supporting shaft 22
(rotational axis line of rotation guiding section 17) as
10 the center. The trajectory drawn when the five rotation
guide plates 27 are rotated is a hollow cylindrical shape,
and the passage supporting plate 23, the bobbin introducing
conveyor 24, the conveyor drive motor 25, and the like are
arranged inside the trajectory.
15 As illustrated in FIG. 3, in a state where the
rotation of the five rotation guide plates 27 is stopped,
the rotation phase is controlled by the cam member 30, to
be described later, so that, out of the five rotation guide
plates, one of the two rotation guide plates 27 adjacent
20 to each other in the circumferential direction is located
in proximity to one end in the width direction of the bobbin
passage 16 and the other rotation guide plate is located
in proximity to the other end in the width direction of the
bobbin passage 16. Therefore, in a state where the rotation
25 of the rotation guide plate 27 is stopped, the passing of
the yarn supplying bobbin 3 supplied from the bobbin feed
conveyor 14 through the bobbin passage 16 is not inhibited
by the rotation guide plate 27.
A pair of end push-out members (convex portions) 27b
30 is arranged on each of the two push-out surfaces 27a of the
rotation guide plate 27. Each end push-out member 27b is
17 / 56
arranged in proximity to the end in the longitudinal
direction of the rotation guide plate 27. Specifically,
the end push-out member 27b located on one end side in the
longitudinal direction of the rotation guide plate 27 is
fixed to the regulation plate 28, and the end push-5 out
member 27b located on the other end side in the longitudinal
direction is fixed to the rotation guide plate 27.
Each end push-out member 27b is configured to project
out from the push-out surface 27a, and the end face in the
10 projecting direction is configured to make contact with the
end of the yarn supplying bobbin 3 (bottom portion 4a or
top portion 4b of core tube 4). As a result, even in a state
where the amount of yarn wound around the yarn supplying
bobbin 3 is small and the yarn supplying bobbin 3 is tilted
15 when the yarn supplying bobbin 3 is pushed out to the side
from the bobbin passage 16 by the push-out surface 27a, the
yarn supplying bobbin 3 can be reliably pushed out without
being tilted by the end push-out member 27b.
A tapered portion is formed on each end push-out
20 member 27b. The tapered portion can prevent the yarn
supplying bobbin 3 passing through the bobbin passage 16
from being caught at the end push-out member 27b.
The pair of end push-out members 27b is both attached
so that the positions thereof are adjustable in the
25 longitudinal direction of the rotation guide plate 27.
Specifically, the position of the regulation plate 28 can
be adjusted in the axis line direction of the rotation
guiding section 17 (details will be described later), and
thus the position of the end push-out member 27b fixed to
30 the regulation plate 28 can also be moved with the
regulation plate 28. Furthermore, the end push-out member
18 / 56
27b at the position away from the regulation plate 28 is
attached by an appropriate fixing member such as a bolt by
way of the long hole formed in the rotation guide plate 27
in the direction along the longitudinal direction of the
rotation guide plate 27, and thus the position of the 5 he end
push-out member 27b can be moved. Thus, the interval of
the two end push-out members 27b can be adjusted, and thus
can be responded flexibly to the yarn supplying bobbin 3
having different lengths.
10 The regulation plate 28 is a plate-shaped member
formed into a ring shape, and is arranged at the downstream
end of the bobbin passage 16. The regulation plate 28 is
arranged in proximity to the rotation supporting plate 26
located downstream of the bobbin passage 16 at between the
15 pair of rotation supporting plates 26. The regulation
plate 28 is provided to connect the five rotation guide
plates 27 in the circumferential direction.
The regulation plate 28 has five insertion holes 28a
which each have a pass-through form and which are formed
20 lineally at equal interval in the circumferential
direction. The five rotation guide plates 27 are inserted
to the insertion holes 28a, respectively. Therefore, the
regulation plate 28 can move along the longitudinal
direction of the rotation guide plate 27 (axis line
25 direction of rotation guiding section 17).
Five L-shaped coupling members are fixed to the
regulation plate 28, and each coupling member is attached
to the rotation guide plate 27 through the long hole (see
FIG. 2). Therefore, the position of the regulation plate
30 28 can be adjusted in the direction parallel to the
longitudinal direction of the rotation guide plate 27
19 / 56
through the long hole. Thus, the yarn supplying bobbin 3
having different lengths can be responded.
As illustrated in FIG. 3, the regulation plate 28 is
configured to make contact with the end on one side of the
yarn supplying bobbin 3 on the downstream side of the bo5 bbin
passage 16. Thus, the yarn supplying bobbin 3 fed by the
bobbin introducing conveyor 24 can be regulated to a
predetermined position, so that the yarn supplying bobbin
3 can be reliably guided by the rotation of the rotation
10 guide plate 27.
The rotation motor 29 is a drive source of the
rotation guiding section 17, and is fixed to the leg portion
21 on one side. The output shaft of the rotation motor 29
is coupled to the rotation supporting plate 26 on one side
15 by a transmission belt 60. Thus, the power of the rotation
motor 29 can be transmitted to the rotation supporting
plate 26 to rotate the rotation guiding section 17
including the five rotation guide plates 27. The rotation
motor 29 is configured as a motor that can rotate forward
20 and backward, and that can control the rotation angle. The
rotation motor 29 can rotate the rotation guiding section
17 by 72°, which is the angle interval of the rotation guide
plate 27, in either direction according to a command from
the control section (details to be described later) adapted
25 to control the bobbin supplying device 10.
The cam member 30 is fixed to the rotation supporting
plate 26 on one side, and can integrally rotate with the
rotation supporting plate 26. Five recesses 30a are formed
at an equal interval (i.e., interval of 72°) in the
30 circumferential direction on the outer periphery of the cam
member 30.
20 / 56
The phase holding arm 31 is supported by the leg
portion 21 on one side so as to be swingable, and a small
roller 31a that can make contact with the outer periphery
of the cam member 30 is rotatably attached to the distal
end of the phase holding arm 31. A spring (not illust5 rated)
is attached to the phase holding arm 31, and an urging force
that pushes the roller 31a against the cam member 30 can
be acted on the phase holding arm 31.
In a state where one of the two rotation guide plates
10 27 adjacent to each other in the circumferential direction
among the five rotation guide plates is located in
proximity to one end in the width direction of the bobbin
passage 16 and the other rotation guide plate is located
in proximity to the other end in the width direction of the
15 bobbin passage 16, the roller 31a at the distal end of the
phase holding arm 31 enters the recess 30a of the cam member
30. Thus, the rotation phase of the rotation guiding
section 17 (rotation guide plate 27) can be appropriately
held at the phase at which the introduction of the yarn
20 supplying bobbin 3 to the bobbin passage 16 is not inhibited
by the rotation guide plate 27.
The feed belt 54 of the bobbin introducing conveyor
24 travels on the circulating path, as described above, in
a space on the inner side surrounded by the rotation guide
25 plate 27. The upper surface of the feed belt 54 that passes
the upper side of the circulating path configures the road
surface of the bobbin passage 16. The five rotation guide
plates 27 surround the road surface of the bobbin passage
16, as illustrated in FIG. 4, when seen in the longitudinal
30 direction of the bobbin passage 16. As illustrated in FIG.
4, the road surface of the bobbin passage 16 is arranged
21 / 56
at the upper end portion in the internal space of the
cylindrical rotational trajectory drawn by the rotation
guide plate 27.
Furthermore, the road surface of the bobbin passage
16 (upper surface of bobbin introducing conveyor 24) 5 is
arranged between the two rotation guide plates 27 located
at the upper part of the five rotation guide plates 27 under
a state where the rotation guiding section 17 is stopped.
The road surface of the bobbin passage 16 is arranged
10 between the ends on the side close to the rotational axis
line of the rotation guiding section 17 in the two rotation
guide plates 27. The interval of the ends on the side close
to the rotational axis line of the rotation guiding section
17 in the two rotation guide plates 27 is substantially
15 equal to the width of the road surface of the bobbin passage
16.
Therefore, the bobbin passage 16 being configured to
surround the lower side and both sides in the width
direction of the yarn supplying bobbin 3 and having the
20 upper side opened is formed by the horizontal road surface
and the pair of rotation guide plates 27 extending from both
ends in the width direction of the road surface. In other
words, when the yarn supplying bobbin 3 is fed from the
bobbin feed conveyor 14 to the bobbin passage 16, the
25 rotation guide plate 27 functions as a side wall guide to
regulate the yarn supplying bobbin 3 so as not to fall out
to the side from the road surface.
The width of the road surface of the bobbin passage
16 is substantially equal to the thickness of the yarn
30 supplying bobbin 3 (thickness of the portion wound with
yarn). The side wall guide is directed diagonally from the
22 / 56
road surface, and thus the bobbin passage 16 is configured
to a tapered shape in which the width of the lower side (side
closer to rotational axis line) is narrow and the width of
the upper side (side distant from rotational axis line) is
wide. Thus, the position of the yarn supplying bobbin 5 3
is less likely to be deviated to the end in the width
direction of the road surface, so that the yarn supplying
bobbin 3 can be smoothly fed along the compact bobbin
passage 16.
10 The conveyor drive motor 25 adapted to drive the
bobbin introducing conveyor 24 is arranged inside the
rotational trajectory of five rotation guide plates 27 with
the bobbin introducing conveyor 24. A simple and compact
configuration for driving the bobbin introducing conveyor
15 24 thus can be realized. On the other hand, in the
configuration, the rotation guide plate 27 rotates the
periphery of the conveyor drive motor 25, and thus the
drawing of an electric wire 25a connected to the conveyor
drive motor 25 is difficult. In this regard, in the present
20 embodiment, the pass-through shaft hole 22a is formed in
the supporting shaft 22 fixed to the leg portion 21, and
the electric wire 25a connected to the conveyor drive motor
25 is passed through the relevant shaft hole 22a (see FIG.
3). Therefore, the power and signal can be externally
25 supplied to the conveyor drive motor 25 without the
electric wiring interfering with the rotation guide plate
27.
The bobbin supplying device 10 includes a sensor 96
adapted to detect that the yarn supplying bobbin 3 fed in
30 the bobbin passage 16 reached a predetermined position (see
FIG. 2). The sensor 96 is configured as a photoelectric
23 / 56
sensor including a light projecting section and a light
receiving section. An optical axis 96a of the sensor 96
is defined so that a position slightly upstream of the
regulation plate 28 in the direction in which the yarn
supplying bobbin 3 moves in the bobbin passage 16, 5 6, the
position being slightly higher than the road surface of the
bobbin passage 16, horizontally passes in the width
direction of the bobbin passage 16. A cutout 27c in which
the side distant from the rotational axis line of the
10 rotation guiding section 17 is cut out to a rectangular
shape is formed in the five rotation guide plates 27 so as
not to shield the light of the sensor 96.
Next, a description will be made on the bobbin
direction aligning device 6 with reference to FIGS. 5 to
15 7. The configuration of the pair of bobbin direction
aligning devices 6 is substantially the same, and thus the
bobbin direction aligning device 6 on one side will be
hereinafter representatively described. FIG. 5 is a
perspective view illustrating a configuration of the
20 bobbin direction aligning device 6 on one side. FIG. 6 is
a view illustrating a state in which the bottom portion 4a
of the yarn supplying bobbin 3 is received by a bottom
portion side receiving portion (first receiving portion)
71 in the core tube guiding path 63 on one side of the bobbin
25 direction aligning device 6. FIG. 7 is a view illustrating
a state in which the top portion 4b of the yarn supplying
bobbin 3 is received by a top portion side receiving portion
(second receiving portion) 72 in the core tube guiding path
63 on the other side of the bobbin direction aligning device
30 6.
The bobbin direction aligning device 6 includes a
24 / 56
pair of side frames 61, an end frame 62, a pair of core tube
guiding paths 63, and an open drive section 64 as a main
configuration.
As illustrated in FIG. 5, the pair of side frames 61
is both configured as a flat plate shaped member. The 5 pair
of side frames 61 is arranged to face each other with a
predetermined interval with the thickness direction
directed in the horizontal direction. The interval of the
side frames 61 is slightly greater than the length in the
10 longitudinal direction of the yarn supplying bobbin 3.
The end frame 62 is configured as a flat plate shaped
member. The end frame 62 is arranged at an end on the side
distant from the bobbin sorting device 5 in the side frame
61 with the thickness direction directed in the horizontal
15 direction. Both ends of the end frame 62 are
perpendicularly coupled with respect to the ends of the
pair of side frames 61, respectively.
A folding-plate shaped guiding frame in which the
side close to the bobbin sorting device 5, the upper side,
20 and the lower side are opened is configured by configuring
the side frame 61 and the end frame 62. The guiding frame
is arranged on the side on one side of the bobbin sorting
device 5 so as to receive the yarn supplying bobbin 3
distributed by the bobbin sorting device 5. As described
25 above, the interval of the pair of side frames 61 is
slightly greater than the length of the yarn supplying
bobbin 3, and thus the yarn supplying bobbin 3 can be passed
in the horizontal orientation, in which the end in the
longitudinal direction is proximate to the respective side
30 frame 61, through the interior of the guiding frame.
The side frame 61 and the end frame 62 are attached
25 / 56
with a fixing member such as a bolt by way of the long hole.
Thus, the interval of the pair of side frames 61 can be
adjusted, so that the yarn supplying bobbin 3 having
different lengths can be flexibly responded.
The core tube guiding path 63 in an inclined 5 form
adapted to guide the core tube 4 of the yarn supplying
bobbin 3 is arranged in each of the pair of side frames 61.
The pair of core tube guiding paths 63 is configured to be
arranged on the inner surface of the side frame 61 so as
10 to face each other.
The core tube guiding path 63 includes an introducing
portion 70, a bottom portion side receiving portion 71, and
a top portion side receiving portion 72, in order from the
side close to the bobbin sorting device 5. The core tube
15 guiding path 63 on one side of the core tube guiding path
63 arranged in a pair is illustrated in FIG. 6, and the core
tube guiding path 63 on the other side is illustrated in
FIG. 7. Thus, the pair of core tube guiding paths 63 has
substantially the same configuration, and are arranged
20 symmetric to each other.
The introducing portion 70, the bottom portion side
receiving portion 71, and the top portion side receiving
portion 72 are configured by attaching a plate-shaped or
a block-shaped member to the inner surface of the side frame
25 61 in a projecting form. The projecting length of the
member attached to the interior of the side frame 61 is
formed to be equal to or slightly shorter than the length
of the exposed portion of the core tube 4 at the end of the
yarn supplying bobbin 3. Thus, when the yarn supplying
30 bobbin 3 is guided by the core tube guiding path 63, the
yarn is less likely to be caught at the member in a
26 / 56
projecting form, and the damage on the yarn layer of the
yarn supplying bobbin 3 can be prevented.
The introducing portion 70 is located upstream in the
direction in which the yarn supplying bobbin 3 moves along
the core tube guiding path 63. As illustrated in FIGS. 5 IGS. 5
to 7, the introducing portion 70 is configured by two
plate-shaped introducing guide members 81, 82.
The introduction guide members 81, 82 are arranged
to project out substantially perpendicularly from the
10 inner surface of the side frame 61. The two introduction
guide members 81, 82 are arranged to sandwich the core tube
guiding path 63 from above and below, and the end of the
core tube 4 of the yarn supplying bobbin 3 can be passed
between the two introduction guide members 81, 82.
15 The vertical interval of the two introduction guide
members 81, 82 is configured such that the side close to
the bobbin sorting device 5 is wide and the side distant
from the bobbin sorting device 5 is narrow. The two
introduction guide members 81, 82 are both inclined so that
20 the side distant from the bobbin sorting device 5 is on the
lower side. Therefore, the yarn supplying bobbin 3 input
between the side frames 61 from the bobbin sorting device
5 has the end entered between the introduction guide
members 81, 82 of the introducing portion 70 to move by its
25 own weight toward the bottom portion side receiving portion
71 on the downstream.
As illustrated in FIG. 6, the bottom portion side
receiving portion 71 includes a fixed side receiving member
(regulation member) 83 and a movable side receiving member
30 (open/close member) 84.
The fixed side receiving member 83 and the movable
27 / 56
side receiving member 84 are formed into a block shape, and
are arranged to project out substantially perpendicularly
from the inner surface of the side frame 61. The fixed side
receiving member 83 and the movable side receiving member
84 are arranged to sandwich the core tube guiding path 5 ath 63
from above and below.
A gap is formed between the lower surface of the fixed
side receiving member 83 located on the upper side of the
core tube guiding path 63 and the upper surface (receiving
10 surface 84a) of the movable side receiving member 84
located on the lower side. The gap is formed so that the
side close to the bobbin sorting device 5 is wide and the
side distant from the bobbin sorting device 5 is narrow.
A width 71w of the narrowest portion in the gap is narrower
15 than the diameter of the bottom portion 4a of the core tube
4 and wider than the diameter of the top portion 4b.
As described above, which way the yarn supplying
bobbin 3 input from the bobbin sorting device 5 to the
bobbin direction aligning device 6 is directed is
20 indefinite. Therefore, the bottom portion side receiving
portion 71 arranged in the respective core tube guiding
path 63 has both cases of a case in which the bottom portion
4a of the core tube 4 is fed and a case in which the top
portion 4b is fed. When the bottom portion 4a of the core
25 tube 4 is fed to the bottom portion side receiving portion
71, the core tube 4 cannot be passed between the fixed side
receiving member 83 and the movable side receiving member
84, and thus is received by the bottom portion side
receiving portion 71 (see FIG. 6). When the top portion
30 4b of the core tube 4 is fed to the bottom portion side
receiving portion 71, the core tube 4 is passed between the
28 / 56
fixed side receiving member 83 and the movable side
receiving member 84, and is moved by its own weight toward
the top portion side receiving portion 72 on the downstream
(see FIG. 7). Thus, the bottom portion side receiving
portion 71 can selectively receive only the bottom 5 portion
4a out of the bottom portion 4a and the top portion 4b of
the core tube 4.
The fixed side receiving member 83 is attached by a
fixing member such as a bolt by way of a long hole. Thus,
10 the position of the fixed side receiving member 83 (i.e.,
width 71w of gap between fixed side receiving member 83 and
movable side receiving member 84) can be adjusted, and thus
can be responded to the yarn supplying bobbins 3 in which
the thicknesses of the core tubes 4 differ from one another.
15 As illustrated in FIGS. 6 and 7, the movable side
receiving member 84 is swingably supported vertically with
the swing supporting point 84b as the center. Therefore,
when the movable side receiving member 84 is swung toward
the lower side from the state illustrated with a broken line
20 in FIGS. 6 and 7, the lower part of the bottom portion side
receiving portion 71 can be opened. As described above,
when the bottom portion 4a of the core tube 4 of the yarn
supplying bobbin 3 is fed to the bottom portion side
receiving portion 71, the bottom portion 4a is received by
25 the bottom portion side receiving portion 71. Therefore,
when the movable side receiving member 84 is swung toward
the lower side in this state, the bottom portion 4a of the
core tube 4 of the yarn supplying bobbin 3 drops by its own
weight.
30 In the pair of core tube guiding paths 63, the movable
side receiving members 84 configuring the bottom portion
29 / 56
side receiving portion 71 are coupled to each other by a
coupling shaft 86. Therefore, the two movable side
receiving members 84 operate in cooperation, and when one
movable side receiving member 84 opens the lower part of
the bottom portion side receiving portion 71, the 5 he other
movable side receiving member 84 also opens the lower part
of the bottom portion side receiving portion 71 at the same
time.
The top portion side receiving portion 72 is arranged
10 to be adjacent on the downstream side to the bottom portion
side receiving portion 71. The top portion side receiving
portion 72 includes a block-shaped receiving member
(supporting member) 85 arranged on the lower side of the
core tube guiding path 63. A V-shaped recess 85a is formed
15 in the upper surface of the receiving member 85.
With this configuration, when the top portion 4b of
the core tube 4 of the yarn supplying bobbin 3 is fed to
the top portion side receiving portion 72, the top portion
4b is received by the recess 85a of the receiving member
20 85, as illustrated in FIG. 7. The recess 85a is formed into
a V-shape, and hence the top portion side receiving portion
72 capable of receiving the top portion 4b at the stable
position can be realized with a simple configuration.
When the top portion 4b is fed to the top portion side
25 receiving portion 72 in the core tube guiding path 63 on
one side, this means that the bottom portion 4a is received
by the bottom portion side receiving portion 71 in the core
tube guiding path 63 on the other side. When the lower part
of the bottom portion side receiving portion 71 is opened
30 and the bottom portion 4a of the core tube 4 is about to
drop, since the top portion 4b is received by the recess
30 / 56
85a, the yarn supplying bobbin 3 drops with the bottom
portion 4a first (i.e., bottom portion 4a on the lower
side).
The discharge guiding member 15 described above is
connected to the lower ends of the pair of side frames 5 mes 61
and the end frame 62. The yarn supplying bobbin 3 dropped
from the core tube guiding path 63 has the orientation
directed vertically by the discharge guiding member 15.
Needless to say, the direction of the yarn supplying bobbin
10 3 is aligned so that the bottom portion 4a is on the lower
side. The vertically directed yarn supplying bobbin 3 is
guided to the bobbin chute 13.
As described above, the yarn supplying bobbin 3 input
from the bobbin sorting device 5 to the bobbin direction
15 aligning device 6 has the bottom portion 4a, which is the
end on one side, received by the bottom portion side
receiving portion 71, and the top portion 4b, which is the
end on the other side, received by the top portion side
receiving portion 72. The introducing portion 70, the
20 bottom portion side receiving portion 71, and the top
portion side receiving portion 72 in the pair of core tube
guiding paths 63 are arranged at positions corresponding
to each other, so that when both ends of the yarn supplying
bobbin 3 are received as described above, the orientation
25 of the yarn supplying bobbin 3 is slightly slanted (see FIGS.
6 and 7). However, since the bottom portion side receiving
portion 71 and the top portion side receiving portion 72
are adjacently arranged in the respective core tube guiding
paths 63, the orientation of the yarn supplying bobbin 3
30 in which both ends are received can be prevented from being
strongly inclined. As a result, the path in which the yarn
31 / 56
supplying bobbin 3 drops from the bobbin direction aligning
device 6 can be set in a narrow range, whereby the first
opening 15a of the discharge guiding member 15 does not need
to be formed large and the miniaturization of the bobbin
5 supplying device 10 can be achieved.
As illustrated in FIG. 2, a sensor 97 is attached to
the end frame 62 of the bobbin direction aligning device
6. The sensor 97 is configured by, for example, a
photoelectric sensor. The sensor 97 can detect the
10 presence/absence of the yarn supplying bobbin 3 in a state
where the ends are received by the bottom portion side
receiving portion 71 and the top portion side receiving
portion 72.
Next, a description will be made on the configuration
15 of the open drive section 64 adapted to drive the movable
side receiving member 84. As illustrated in FIGS. 5 and
7, a rotary solenoid 91 serving as an actuator is attached
to one side of the side frame 61 arranged in a pair. The
coupling shaft 86 adapted to couple the movable side
20 receiving members 84 in the pair of core tube guiding paths
63 is passed through and projected out from the side frame
61 on the side where the rotary solenoid 91 is arranged,
and the arm 92 is fixed to such a projecting portion. A
movable element of the rotary solenoid 91 and a distal end
25 portion of the arm 92 are coupled to each other by a link
member 93. Thus, the pair of movable side receiving members
84 can be switched between a close position indicated with
a broken line and an open position indicated with a chain
line in FIGS. 6 and 7 by driving the rotary solenoid 91.
30 Thus, the bobbin direction aligning device 6 of the
present embodiment includes the bottom portion side
32 / 56
receiving portion 71 and the top portion side receiving
portion 72 of the pair of core tube guiding paths 63 formed
in an inclined manner, thus receiving the bottom portion
4a and the top portion 4b of the core tube 4 of the yarn
supplying bobbin 3 that moves by its own weight, 5 at
different locations. The lower part of the bottom portion
side receiving portion 71 adapted to receive the bottom
portion 4a of the core tube 4 is opened, so that the yarn
supplying bobbin 3 drops first from the bottom portion 4a
10 side of the core tube 4. Therefore, irrespective of the
direction of the yarn supplying bobbin 3 supplied to the
bobbin direction aligning device 6, the direction of the
yarn supplying bobbin 3 can be aligned with the bottom
portion 4a of the core tube 4 directed toward the lower side
15 and discharged toward the downstream.
In other words, the bobbin direction aligning device
6 of the present embodiment can align the direction of the
yarn supplying bobbin 3 by simply carrying out a lower side
opening operation of the movable side receiving member 84
20 without requiring determination in the direction of the
yarn supplying bobbin 3 by the sensor and the like.
Furthermore, a mechanism adapted to move the yarn supplying
bobbin 3 in the longitudinal direction is not required, so
that the bobbin direction aligning device 6 can be
25 compactly configured.
Next, a description will be made on the configuration
for controlling the bobbin supplying device 10. FIG. 8 is
a block diagram describing the control of the bobbin
supplying device 10.
30 As illustrated in FIG. 8, the bobbin supplying device
10 includes the control section 90. The control section
33 / 56
90 is configured by hardware such as CPU, ROM, and RAM (not
illustrated), and software such as a control program stored
in the ROM.
The sensor 96 arranged in the bobbin sorting device
5 and the sensor 97 arranged in the pair of bobbin dir5 ection
aligning devices 6 are respectively electrically connected
to the control section 90. The pair of bobbin chutes 13
include a sensor (not illustrated) adapted to detect the
presence/absence of the yarn supplying bobbin 3. The
10 sensor is electrically connected to the control section 90.
When the sensor detects that the yarn supplying
bobbin 3 is not present in at least one of the pair of bobbin
chutes 13 with this configuration, the control section 90
examines with the sensor 97 whether the yarn supplying
15 bobbin 3 is received by the bottom portion side receiving
portion 71 and the top portion side receiving portion 72
in the bobbin direction aligning device 6 connected to the
bobbin chute 13. When the yarn supplying bobbin 3 in the
received state is present, the control section 90 operates
20 the bobbin direction aligning device 6 (rotary solenoid 91),
opens the receiving surface 84a of the bottom portion side
receiving portion 71, and supplies the yarn supplying
bobbin 3 to the bobbin chute 13.
When the sensor 97 detects that the yarn supplying
25 bobbin 3 is not received by the bottom portion side
receiving portion 71 and the top portion side receiving
portion 72 in at least one of the pair of bobbin direction
aligning devices 6, the control section 90 examines with
the sensor 96 whether the yarn supplying bobbin 3 is present
30 in the bobbin passage 16 of the bobbin sorting device 5.
When the yarn supplying bobbin 3 is present in the bobbin
34 / 56
passage 16, the control section 90 drives the rotation
motor 29 of the bobbin sorting device 5 to rotate the
rotation guide plate 27 by 72°, and supplies the yarn
supplying bobbin 3 on the bobbin passage 16 by being pushed
out with the rotation guide plate 27 toward the 5 bobbin
direction aligning device 6 on the side in which the yarn
supplying bobbin 3 is not present. As described above, to
which bobbin direction aligning device 6 the yarn supplying
bobbin 3 is to be supplied can be switched by the rotation
10 direction of the rotation guiding section 17 (rotation
guide plate 27). When the yarn supplying bobbin 3 is not
present in the bobbin passage 16, the control section 90
waits until the sensor 96 detects the yarn supplying bobbin
3 while controlling the bobbin feed conveyor 14 and the
15 bobbin sorting device 5 (conveyor drive motor 25) to feed
the yarn supplying bobbin 3 to the bobbin passage 16.
When the yarn supplying bobbin 3 is present in the
bobbin chute 13, the control section 90 waits without
opening the receiving surface 84a of the bottom portion
20 side receiving portion 71 in the bobbin direction aligning
device 6 upstream of the bobbin chute 13. When the yarn
supplying bobbin 3 is received by the bottom portion side
receiving portion 71 and the top portion side receiving
portion 72 in both of the pair of bobbin direction aligning
25 device 6, the control section 90 waits without rotating the
rotation guide plate 27 in either direction in the bobbin
sorting device 5. Thus, the impact and the like of the yarn
supplying bobbin 3 can be prevented.
Thus, the control section 90 distributes, in a
30 balanced manner, the yarn supplying bobbin 3 supplied to
the bobbin sorting device 5 at an appropriate timing based
35 / 56
on the detection results of the sensors arranged in the
bobbin sorting device 5, the bobbin direction aligning
device 6, and the bobbin chute 13. The control section 90
supplies the yarn supplying bobbins 3 sorted to the two
bobbin direction aligning devices 6 to the bobbin chute 5 13
each at an appropriate timing. The yarn supplying bobbins
3 supplied to the bobbin chute 13 in a state where the
orientation is aligned are mounted on the feeding tray 2
by the bobbin chute 13.
10 The bobbin supplying device 10 is configured as above,
and thus the yarn supplying bobbins 3 can be simultaneously
mounted and supplied in a parallel manner to each feeding
tray 2 fed in the two paths, as illustrated in FIG. 1. As
a result, the supplying performance of the yarn supplying
15 bobbin 3 can be enhanced, whereby the efficiency of the
entire bobbin supplying device 10 can be enhanced.
As described above, the bobbin sorting device 5 of
the present embodiment includes the bobbin passage 16 and
the rotation guiding section 17. The bobbin passage 16 is
20 adapted to transport the supplied yarn supplying bobbin 3.
The rotation guiding section 17 distributes the yarn
supplying bobbin 3 from the bobbin passage 16 to the
plurality of supplying paths 8. The rotation guiding
section 17 includes a plurality of rotation guide plates
25 27. The plurality of rotation guide plates 27 are arranged
at plural areas at the periphery of the road surface of the
bobbin passage 16 when viewed in the transporting direction
of the bobbin passage 16.
Thus, a layout in which the road surface of the bobbin
30 passage 16 passes through the interior surrounded by the
rotation guide plates 27 can be realized, whereby the
36 / 56
bobbin passage 16 and the rotation guide plate 27 can be
compactly arranged as a whole. As a result, the space of
the bobbin sorting device 5 can be saved.
Furthermore, in the bobbin sorting device 5 of the
present embodiment, the rotation guiding section 5 17
rotates with a rotational axis center, which is parallel
to the transporting direction of the bobbin passage 16, as
a center.
Thus, the movement trajectory of the rotation guide
10 plate 27 surrounding the road surface of the bobbin passage
16 can be compactly configured. Moreover, the layout in
which the road surface of the bobbin passage 16 passes
through the interior of the movement trajectory
(rotational trajectory) of the rotation guide plate 27 is
15 realized, whereby the bobbin passage 16 and the rotation
guide plate 27 can be more compactly arranged as a whole.
The rotation guiding section 17 can push out the yarn
supplying bobbin 3 so as to lie along the distributing
direction of the yarn supplying bobbin 3, and hence the yarn
20 supplying bobbin 3 can be reliably pushed out from the
bobbin passage 16.
The bobbin sorting device 5 of the present embodiment
further includes the rotation motor 29 for rotationally
driving the rotation guiding section 17. The rotation
25 guiding section 17 is configured to be able to
forward/reverse rotate by the rotation motor 29.
The direction in which the rotation guide plate 27
pushes out the yarn supplying bobbin 3 thus can be switched
by the rotating direction of the rotation guiding section
30 17. As a result, the yarn supplying bobbins 3 can be pushed
and distributed in different directions.
37 / 56
In the bobbin sorting device 5 of the present
embodiment, the plurality of rotation guide plates 27 are
arranged in a line at an equal interval along a virtual
circle having the rotational axis line of the rotation
5 guiding section 17 as the center.
Since the plurality of rotation guide plates 27 are
arranged at an equal interval, the rotation of the rotation
guide plate 27 can be easily controlled. A space is thereby
formed on the inner peripheral side of the plurality of
10 rotation guide plates 27 arranged in such manner, so that
various types of members (bobbin introducing conveyor 24,
etc.) can be arranged in such space, and the bobbin sorting
device 5 can be more compactly configured.
Moreover, in the bobbin sorting device 5 of the
15 present embodiment, each of the plurality of rotation guide
plates 27 is configured as a plate member having a push-out
surface 27a orthogonal to a tangent line of the virtual
circle. The push-out surface 27a includes an end push-out
member 27b adapted to push out the end of the yarn supplying
20 bobbin 3.
Thus, the end around which the yarn is not wound in
the yarn supplying bobbin 3 can be pushed out with the end
push-out member 27b, whereby the yarn supplying bobbin 3
can be reliably pushed out regardless of the extent of the
25 amount of yarn wound around the yarn supplying bobbin 3.
Furthermore, in the bobbin sorting device 5 of the
present embodiment, the end push-out member 27b is arranged
in each of the two push-out surfaces 27a orthogonal to the
tangent line of the virtual circle in the rotation guide
30 plate 27.
Thus, regardless of with which one of the push-out
38 / 56
surfaces 27a of the rotation guide plate 27 the yarn
supplying bobbin 3 is pushed, the yarn supplying bobbin 3
can be reliably pushed out from the bobbin passage 16.
In the bobbin sorting device 5 of the present
embodiment, the position of the end push-out member 27b 5 7b in
the push-out surface 27a is adjustable.
Thus, the yarn supplying bobbin 3 of different
lengths can be responded.
In the bobbin sorting device 5 of the present
10 embodiment, the plurality of rotation guide plates 27 have
substantially the same length as the length of the bobbin
passage 16 in the transporting direction.
Thus, the rotation guide plate 27 is able to cover
the entire surface in the transporting direction of the
15 bobbin passage 16, whereby the yarn supplying bobbin 3 can
be reliably pushed out from the bobbin passage 16.
The bobbin sorting device 5 of the present embodiment
further includes a cam member 30 with a recess 30a of the
same number as the rotation guide plate 27. The cam member
20 30 is configured to cooperatively operate with the rotation
guide plate 27. When the rotation guiding section 17 is
held at a stop position by the holding action of the recess
30a of the cam member 30, the yarn supplying bobbin 3 is
transported to the bobbin passage 16.
25 Thus, the position of the rotation guide plate 27 can
be accurately controlled using the cam member 30, and even
when the rotation motor 29 adapted to drive the rotation
guide plate 27 is stopped, the rotation guide plate 27 can
be stably held so as not to move from the predetermined stop
30 position. The stop position of the rotation guide plate
27 is set so as not to interfere with the yarn supplying
39 / 56
bobbin 3 introduced into the bobbin passage 16, so that the
yarn supplying bobbin 3 can smoothly pass the bobbin
passage 16.
Furthermore, in the bobbin sorting device 5 of the
present embodiment, the plurality of rotation guide 5 plates
27 are configured to rotate with a rotational axis line as
a center. The road surface of the bobbin passage 16 is
arranged in proximity to the inner peripheral side of the
rotational trajectory of the plurality of rotation guide
10 plates 27. In the plurality of rotation guide plates 27,
the interval of the ends on the side close to the rotational
axis line in the two adjacent rotation guide plates 27 is
substantially equal to the width of the road surface of the
bobbin passage 16. The interval of the ends on the side
15 distant from the rotational axis line is wider than the
width of the road surface of the bobbin passage 16.
Thus, the two rotation guide plates 27 are arranged
to project out diagonally from the proximity of the ends
in the width direction of the road surface of the bobbin
20 passage 16, whereby the yarn supplying bobbin 3 can be
prevented from dropping off from the bobbin passage 16
while being introduced. Furthermore, since the end on the
side close to the rotational axis line in the rotation guide
plate 27 is arranged in proximity to the one side end in
25 the width direction of the road surface of the bobbin
passage 16, the rotation guide plate 27 can be avoided from
greatly separating away from the road surface of the bobbin
passage 16 when rotating. As a result, the yarn supplying
bobbin 3 of the bobbin passage 16 can be reliably pushed
30 out by the rotation guide plate 27.
Furthermore, in the bobbin sorting device 5 of the
40 / 56
present embodiment, the road surface of the bobbin passage
16 is formed by the feed belt 54. The bobbin sorting device
5 further includes a conveyor drive motor 25 adapted to
drive the feed belt 54. The plurality of rotation guide
plates 27 are arranged at plural areas at the periphery 5 hery of
the conveyor drive motor 25 when viewed in the transporting
direction of the bobbin passage 16.
Thus, the space to arrange the conveyor drive motor
25 does not need to be separately provided, and the bobbin
10 sorting device 5 can be more compactly configured.
Furthermore, in the bobbin sorting device 5 of the
present embodiment, the plurality of rotation guide plates
27 are rotatably supported by way of a hollow supporting
shaft 22.
15 Thus, by using a hollow portion formed in the
supporting shaft 22, other members (e.g., electric wire
25a, etc.) can be passed without interfering with the
rotation guide plate 27.
The bobbin sorting device 5 of the present embodiment
20 further includes a regulation plate 28 adapted to make
contact with the yarn supplying bobbin 3 transported by the
bobbin passage 16 and stop the yarn supplying bobbin 3 at
a predetermined position.
Thus, the yarn supplying bobbin 3 can be stopped at
25 a predetermined position on the bobbin passage 16, whereby
the yarn supplying bobbin 3 can be reliably pushed out and
distributed by the rotation guiding section 17.
In the bobbin sorting device 5 of the present
embodiment, the regulation plate 28 is arranged downstream
30 in the transporting direction of the bobbin passage 16, and
is adapted to make contact with the end of the yarn
41 / 56
supplying bobbin 3 to stop the yarn supplying bobbin 3.
Thus, the yarn supplying bobbin 3 can be stopped at
a prescribed position having the end of the yarn supplying
bobbin 3 as the reference by bringing the end located on
the head side in the yarn supplying bobbin 3 5 transported
by the bobbin passage 16 into contact with the regulation
plate 28.
Furthermore, in the bobbin sorting device 5 of the
present embodiment, the width of the road surface of the
10 bobbin passage 16 is substantially equal to the thickness
of the yarn supplying bobbin 3.
Thus, the bobbin passage 16 can be compactly
configured, so that the space of the bobbin sorting device
5 can be further saved.
15 In the bobbin sorting device 5 of the present
embodiment, five rotation guide plates 27 are arranged.
Thus, the ensuring of the width of the road surface
of the bobbin passage 16, and the miniaturization of the
rotational trajectory of the rotation guide plate 27 are
20 both achieved. Furthermore, the yarn supplying bobbin 3
can be reliably pushed out without greatly enlarging the
drive angle of the rotation guide plate 27.
The bobbin supplying device 10 of the present
embodiment includes the bobbin sorting device 5 and two
25 supplying paths 8. The yarn supplying bobbin 3 distributed
by the bobbin sorting device 5 is supplied to the supplying
path 8. The bobbin direction aligning device 6 and the
bobbin chute 13 are arranged in each of the two supplying
paths 8. The bobbin direction aligning device 6 changes
30 the direction of the supplied yarn supplying bobbin 3. The
bobbin chute 13 is arranged downstream of the bobbin
42 / 56
direction aligning device 6, and mounts the yarn supplying
bobbin 3, which direction is changed, on the transporting
member.
Thus, the yarn supplying bobbin 3 sorted by the
bobbin sorting device 5 can be mounted on the feeding 5 g tray
2 with the plurality of bobbin direction aligning devices
6 and the bobbin chute 13, so that the supplying efficiency
of the entire bobbin supplying device 10 can be enhanced.
In the bobbin supplying device 10 of the present
10 embodiment, a control section 90 adapted to operate the
rotation guiding section 17 of the bobbin sorting device
5 to distribute the yarn supplying bobbin 3 is arranged.
The control section 90 operates the rotation guiding
section 17 in accordance with the operation state in the
15 device (bobbin direction aligning device 6) of the
respective supplying paths 8.
Thus, for example, when the yarn supplying bobbin 3
is retained in the bobbin direction aligning device 6 on
one side, the bobbin sorting device 5 can be operated to
20 sort the yarn supplying bobbin 3 to the bobbin direction
aligning device 6 on the other side. Thus, the supplying
efficiency of the yarn supplying bobbin 3 can be entirely
enhanced.
Preferred embodiments of the present invention have
25 been described above, but the above-described
configurations may be modified as below.
The number of rotation guide plates 27 is not limited
to five, and may be, for example, two, three, four, or six
or more.
30 The length of the rotation guide plate 27 is not
limited to substantially the same length as the bobbin
43 / 56
passage 16, and may be formed longer than the bobbin passage
16. Furthermore, in place of the end push-out member 27b,
the end of the yarn supplying bobbin 3 may be pushed with
a protrusion integrally formed on the rotation guide plate
5 27.
The bobbin introducing conveyor 24 may be omitted,
and the bobbin passage 16 may be formed in an inclined
manner such that the downstream side becomes the lower
side, so that the yarn supplying bobbin 3 can pass the
10 bobbin passage 16 by its own weight. In this case, the road
surface of the bobbin passage 16 is preferably configured
with a flat plate-shaped member that easily slides, or
configured with a plurality of rollable rollers.
A recess may be formed at the distal end portion of
15 the phase holding arm 31, and the phase of the rotation
guiding section 17 may be held so that the relative
projection of the cam member 30 enters the recess.
The configuration of the push-out member is not
limited to the description made above, and for example,
20 five round bars may be arranged in place of the rotation
guide plate 27.
The regulation plate 28 may be integrally formed with
the rotation supporting plate 26 arranged downstream of the
bobbin passage 16.
25 The number of supplying path 8 is not limited two,
and may be three or more. In this case, for example, the
bobbin sorting device 5 is installed in plurals, so that
the yarn supplying bobbins 3 can be distributed to three
or more supplying paths.
30 Thus, a layout in which the road surface of the bobbin
passage passes through the interior surrounded by the
44 / 56
push-out members can be realized, whereby the bobbin
passage and the push-out member can be compactly arranged
as a whole. As a result, the space of the yarn supplying
bobbin distributing device can be saved.
In the yarn supplying bobbin distributing 5 istributing device,
the bobbin distributing section preferably rotates with a
rotational axis line parallel to the transporting
direction of the bobbin passage as a center.
Thus, the moving trajectory of the push-out member
10 surrounding the road surface of the bobbin passage can be
compactly configured. Moreover, since the layout in which
the road surface of the bobbin passage passes through the
interior of the movement trajectory (rotational
trajectory) of the push-out member is realized, the bobbin
15 passage and the push-out member can be arranged more
compactly as a whole. The bobbin distributing section can
push out the yarn supplying bobbin so as to lie along the
distributing direction of the yarn supplying bobbin,
whereby the yarn supplying bobbin can be reliably pushed
20 out from the bobbin passage.
The above-described yarn supplying bobbin
distributing device preferably has the following
configuration. In other words, the above-described yarn
supplying bobbin distributing device further includes a
25 drive source adapted to rotationally drive the bobbin
distributing section. The bobbin distributing section is
configured to forward/reverse rotate by the drive source.
The direction in which the push-out member pushes out
the yarn supplying bobbin thus can be switched by the
30 rotating direction of the bobbin distributing section. As
a result, the yarn supplying bobbins can be pushed and
45 / 56
distributed in different directions.
In the yarn supplying bobbin distributing device
described above, the plurality of push-out members are
preferably arranged lined at an equal interval along a
virtual circle having the rotational axis line as a c5 enter.
Since the plurality of push-out members are arranged
at an equal interval, the rotation of the push-out member
can be easily controlled. A space is formed on the inner
peripheral side of the plurality of push-out members
10 arranged in such manner, so that various types of members
can be arranged in such space, and the yarn supplying bobbin
distributing device can be more compactly configured.
The above-described yarn supplying bobbin
distributing device preferably has the following
15 configuration. In other words, each of the plurality of
push-out members is a plate member having a push-out
surface orthogonal to a tangent line of the virtual circle.
The push-out surface includes a projection adapted to push
out an end of the yarn supplying bobbin.
20 Thus, the end around which the yarn is not wound in
the yarn supplying bobbin can be pushed out with the
projection, whereby the yarn supplying bobbin can be
reliably pushed out regardless of the extent of the amount
of yarn wound around the yarn supplying bobbin.
25 In the yarn supplying bobbin distributing device
described above, the projection is preferably arranged on
each of the two push-out surfaces orthogonal to the tangent
line of the virtual circle in the push-out member.
Thus, regardless of with which one of the push-out
30 surfaces of the push-out member the yarn supplying bobbin
is pushed, the yarn supplying bobbin can be reliably pushed
46 / 56
out from the bobbin passage.
In the yarn supplying bobbin distributing device
described above, a position of the projection in the
push-out surface is preferably adjustable.
Thus, the yarn supplying bobbin of different 5 ifferent lengths
can be responded.
In the yarn supplying bobbin distributing device,
the plurality of push-out members preferably have a length
substantially the same as a length of the bobbin passage
10 in the transporting direction or a length longer than the
bobbin passage.
Thus, the push-out member is able to cover
substantially the entire surface in the transporting
direction of the bobbin passage, whereby the yarn supplying
15 bobbin can be reliably pushed out from the bobbin passage.
The above-described yarn supplying bobbin
distributing device preferably has the following
configuration. In other words, a cam member including a
recess of the same number as the plurality of push-out
20 members is arranged. The cam member is configured to
cooperatively operate with the push-out member. When the
bobbin distributing section is held at a stop position by
a holding action of the recess of the cam member, the yarn
supplying bobbin is transported to the bobbin passage.
25 Thus, the position of the push-out member can be
accurately controlled using the cam member, and even when
the drive source adapted to drive the push-out member is
stopped, the push-out member can be stably held so as not
to move from the predetermined stop position. The stop
30 position of the push-out member is set so as not to
interfere with the yarn supplying bobbin introduced into
47 / 56
the bobbin passage, so that the yarn supplying bobbin can
smoothly pass the bobbin passage.
The above-described yarn supplying bobbin
distributing device preferably has the following
configuration. In other words, the plurality of push-5 out
members are configured to rotate with a rotational axis
line as a center. The road surface of the bobbin passage
is arranged in proximity to an inner circumferential side
of a rotational trajectory of the plurality of push-out
10 members. In the plurality of push-out members, an interval
between ends on a side close to the rotational axis line
in the two adjacent push-out members is substantially equal
to a width of the road surface of the bobbin passage. An
interval between ends on a side distant from the rotational
15 axis line in the two push-out members is wider than a width
of the road surface of the bobbin passage.
Thus, the two push-out members are arranged to
project out diagonally from the proximity of the ends in
the width direction of the road surface of the bobbin
20 passage, whereby the yarn supplying bobbin can be prevented
from dropping off from the bobbin passage while being
introduced. Furthermore, since the end on the side close
to the rotational axis line in the push-out member is
arranged in proximity to the one side end in the width
25 direction of the road surface of the bobbin passage, the
push-out member can be avoided from greatly separating away
from the road surface of the bobbin passage when rotating.
As a result, the yarn supplying bobbin of the bobbin passage
can be reliably pushed out by the push-out member.
30 The above-described yarn supplying bobbin
distributing device preferably has the following
48 / 56
configuration. In other words, the road surface of the
bobbin passage is formed by a conveyor belt. The
above-described yarn supplying bobbin distributing device
further includes a conveyor drive source adapted to drive
the conveyor belt. The plurality of push-out members 5 rs are
arranged at plural areas at a periphery of the conveyor
drive source when viewed in a transporting direction of the
bobbin passage.
Thus, the space to arrange the conveyor drive motor
10 does not need to be separately provided, and the yarn
supplying bobbin distributing device can be more compactly
configured.
In the yarn supplying bobbin distributing device
described above, the plurality of push-out members are
15 preferably rotatably supported through a hollow shaft
member.
Thus, by using a hollow portion formed in the shaft
member, other members (e.g., electric wire, etc.) can be
passed without interfering with the push-out member.
20 In the yarn supplying bobbin distributing device
described above, a bobbin regulation member adapted to make
contact with the yarn supplying bobbin transported by the
bobbin passage to stop the yarn supplying bobbin at a
predetermined position is preferably further arranged.
25 Thus, the yarn supplying bobbin can be stopped at a
predetermined position on the bobbin passage, whereby the
yarn supplying bobbin can be reliably pushed out and
distributed by the bobbin distributing section.
In the yarn supplying bobbin distributing device
30 described above, the bobbin regulation member is
preferably arranged downstream in the transporting
49 / 56
direction of the bobbin passage, and is preferably adapted
to make contact with the end of the yarn supplying bobbin
to stop the yarn supplying bobbin.
Thus, the yarn supplying bobbin can be stopped at a
prescribed position having the end of the yarn supp5 lying
bobbin as the reference by bringing the end located on the
head side in the yarn supplying bobbin transported by the
bobbin passage into contact with the bobbin regulation
member.
10 In the yarn supplying bobbin distributing device
described above, a width of the road surface of the bobbin
passage is preferably substantially equal to a thickness
of the yarn supplying bobbin.
Thus, the introducing path can be compactly
15 configured, whereby the space of the yarn supplying bobbin
distributing device can be further saved.
In the yarn supplying bobbin distributing device
described above, five push-out members are preferably
arranged.
20 Thus, the ensuring of the width of the bobbin
passage, and the miniaturization of the rotational
trajectory of the push-out member can both be achieved.
Furthermore, the yarn supplying bobbin can be reliably
pushed out without greatly enlarging the drive angle of the
25 push-out member.
According to a second aspect of the present
invention, a bobbin supplying system having the following
configuration is provided. In other words, the bobbin
supplying system includes the yarn supplying bobbin
30 distributing device, and a plurality of supplying paths.
The yarn supplying bobbin distributed by the yarn supplying
50 / 56
bobbin distributing device is supplied to the supplying
path. Each of the plurality of supplying paths is arranged
with a yarn supplying bobbin direction changing device and
a bobbin mounting device. The yarn supplying bobbin
direction changing device is adapted to change a dire5 ction
of the supplied yarn supplying bobbin. The bobbin mounting
device is arranged downstream of the yarn supplying bobbin
direction changing device and is adapted to mount the yarn
supplying bobbin, which direction is changed, on a
10 transporting member.
Thus, the yarn supplying bobbin distributed by the
yarn supplying bobbin distributing device can be mounted
on the transporting member by the plurality of yarn
supplying bobbin direction changing devices and the bobbin
15 mounting device, so that the supplying efficiency of the
entire bobbin supplying system can be enhanced.
The above-described bobbin supplying system
preferably has the following configuration. In other
words, the bobbin supplying system includes a control
20 section adapted to operate the bobbin distributing section
of the yarn supplying bobbin distributing device to
distribute the yarn supplying bobbin. The control section
operates the bobbin distributing section according to an
operation state in a device of each supplying path.
25 Thus, for example, when the yarn supplying bobbin is
retained in the yarn supplying bobbin direction changing
device on one side, the yarn supplying bobbin distributing
device can be operated to sort the yarn supplying bobbin
to the yarn supplying bobbin direction changing device on
30 the other side. Thus, the supplying efficiency of the yarn
supplying bobbin can be entirely enhanced.
