WINDING DEVICE
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a technique of a winding
device adapted to wind a spun yarn to form a package.
2. Description of the Related Art
Conventionally, there is known a winding device adapted to
wind a spun yarn unwound from a yarn supplying bobbin to form a
package (see e. g., Japanese Unexamined Patent Publication No.
2011-6179) . The winding device includes a bobbin supporting
section for supporting the yarn supplying bobbin. There also
exists a winding device adapted to supply the yarn supplying bobbin
from a bobbin supplying section to the bobbin supporting section.
The bobbin supplying section is mainly configured by a
magazine and a guiding passage. The magazine is provided with a
plurality of through-holes in a circumferential direction, so that
the yarn supplying bobbins can be accommodated in the through-holes.
The guiding passage guides the yarn supplying bobbin accommodated
in the through-hole to the bobbin supporting section. Specifically,
the magazine can intermittently rotate so that the through-hole
stops at a predetermined position. The yarn supplying bobbin
accommodated in the through-hole is dropped by force of gravity
when the through-hole stops at the predetermined position. The
guiding passage can guide the dropped yarn supplying bobbin to the
bobbin supporting section.
Therefore, the yarn supplying bobbin cannot be inserted to
one of the plurality of through-holes formed in the magazine. That
is, since the one through-hole is communicated with the bobbin
supporting section via the guiding passage, if the yarn supplying
bobbin is inserted to such a through-hole, the yarn supplying bobbin
may be unintentionally supplied to the bobbin supporting section.
Thus, if the magazine provided with nine through-holes is
2/19
arranged, for example, the yarn supplying bobbin is allowed to be
inserted to only eight through-holes. However, if an operator
mistakenly inserts the yarn supplying bobbin, problems have
occurred in which the yarn supplying bobbin may be supplied to the
bobbin supporting section that is not in a state of supporting the
yarn supplying bobbin, or the yarn supplying bobbin may be further
supplied to the bobbin supporting section that is already supporting
the yarn supplying bobbin.
BRIEF SUMMARY OF THE INVENTION
The present invention has been made to solve the above
problems, and an object thereof is to provide a winding device
including a bobbin supplying section in which a yarn supplying
bobbin can be inserted to all the through-holes.
The present invention provides a winding device including a
winding section adapted to wind a spun yarn wound around a yarn
supplying bobbin to form a package, a bobbin supporting section
adapted to support the yarn supplying bobbin, and a bobbin supplying
section adapted to supply the yarn supplying bobbin to the bobbin
supporting section, wherein the bobbin supplying section includes
a magazine provided with a plurality of through-holes in a
circumferential direction, a guiding passage arranged towards a
part of the plurality of through-holes, a plate member arranged
on one side of the through-holes excluding the through-hole to which
the guiding passage is directed to hold the yarn supplying bobbins
inserted to the through-holes excluding the through-hole to which
the guiding passage is directed, and an open/close mechanism for
communicating or blocking the guiding passage and the through-hole
on which the plate member is not arranged, and the open/close
mechanism is movable by a driving device adapted to rotate the
magazine.
In the present invention, the open/close mechanism further
includes an open/close member, the open/close member being a shutter
member that moves parallel to the plate member.
3/19
In the present invention, the driving device includes a
magazine gear adapted to rotate integrally with the magazine, a
feeding claw adapted to rotate the magazine gear in one direction,
and a feeding lever adapted to push the feeding claw, the
through-hole in which the plate member is not arranged is opened
or closed by the shutter member when the feeding lever is swung
in one direction, the through-hole in which the plate member is
not arranged is closed or opened by the shutter member when the
feeding lever is swung to the other direction, and the feeding claw
rotates the magazine together with the magazine gear.
In the present invention, the shutter member is attached to
the feeding lever, and the feeding lever is swung by a dedicated
power source for driving the bobbin supplying section.
In the present invention, the feeding lever is swung using
a power of a stepping motor.
In the present invention, the open/close mechanism includes
a detection device adapted to detect whether or not the shutter
member is supporting the yarn supplying bobbin.
The present invention relates to an automatic winder
including a plurality of the winding devices according to the
present invention.
The present invention has the following effects.
According to the present invention, since the winding device
includes the open/close mechanism for communicating or blocking
the guiding passage and the through-hole on which the plate member
is not arranged, the yarn supplying bobbin can be inserted to all
the through-holes. The inserting operation of the yarn supplying
bobbin by an operator is thus simplified. The frequency of the
inserting operation can also be reduced. Furthermore, since the
open/close mechanism is configured by the open/close member for
opening or closing the through-hole in which the plate member is
not arranged and is movable by the driving device adapted to rotate
the magazine, the operation of the magazine and the operation of
the open/close mechanism can be performed in conjunction with each
4/19
other.
According to the present invention, since the shutter member
moves parallel to the plate member, the miniaturization of the
open/close mechanism can be achieved.
According to the present invention, since the shutter member
is movable by the driving device adapted to rotate the magazine,
the operation of the magazine and the operation of the open/close
mechanism can be easily performed in conjunction with each other.
According to the present invention, since the feeding lever
is swung by the dedicated power source for driving the bobbin
supplying section, bobbin replacement of high degree of freedom
that is not influenced by the operation of other main body mechanisms
can be realized.
According to the present invention, since the feeding lever
is swung by using the power of the stepping motor, the failure of
the open/close mechanism and the driving device can be prevented
even when the yarn supplying bobbin is stuck between the shutter
member and the plate member, and the like.
According to the present invention, since whether or not the
shutter member is supporting the yarn supplying bobbin can be
detected, stopping of the operation of the winding device that
occurs when the yarn supplying bobbin is not inserted to the magazine
can be prevented.
According to the present invention, the effect that the
inserting operation of the yarn supplying bobbin by the operator
can be simplified is enhanced by arranging a plurality of winding
devices. The effect of reducing the frequency of the inserting
operation is also enhanced.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
First, a winding device 100 according to one embodiment of
the present invention will be described.
FIG. 1 is a view illustrating an overall structure of the
winding device 100. An arrow in the figure indicates a feeding
direction of a spun yarn Y.
The winding device 100 includes a bobbin supporting section
1. A yarn supplying bobbin SB, around which the spun yarn Y is wound,
is mounted to the bobbin supporting section 1. The winding device
100 includes a yarn unwinding assisting section 2, a tension
applying section 3, a tension detecting section 4, a yarn joining
section 5, a yarn detecting section 6, a traversing section 7, and
a winding section 8 along the feeding direction of the spun yarn
Y unwound from the yarn supplying bobbin SB. The winding device
100 also includes a bobbin supplying section 9.
The yarn unwinding assisting section 2 assists the unwinding
of the spun yarn Y wound around the yarn supplying bobbin SB. The
yarn unwinding assisting section 2 restricts the spun yarn Y unwound
from the yarn supplying bobbin SB from spreading by centrifugal
force.
The tension applying section 3 applies a predetermined
tension on the spun yarn Y unwound from the yarn supplying bobbin
SB. The tension applying section 3 enables high-speed winding of
the spun yarn Y by applying a predetermined tension on the spun
yarn Y. As the tension applying section 3, a disc type tensor, and
the like may also be employed in addition to a gate type tensor
6/19
that applies the tension on the spun yarn Y by comb teeth.
The tension detecting section 4 detects the tension applied
on the spun yarn Y. The tension detecting section 4 can detect the
tension applied on the spun yarn Y based on a voltage value that
changes according to the tension of the spun yarn Y. Specifically,
a control section analyzes a detection signal from the tension
detecting section 4 to grasp the tension applied on the spun yarn
Y.
The yarn joining section 5 joins ends of the spun yarn Y to
each other. When the spun yarn Y is broken, for example, the yarn
joining section 5 joins the ends of the disconnected spun yarn Y
to each other. As the yarn joining section 5, a mechanical splicer
and the like may be employed in addition to an air splicer that
joins the ends of the spun yarn Y by a whirling airflow.
The yarn detecting section 6 detects a defective part of the
spun yarn Y. The yarn detecting section 6 detects yarn breakage
of the spun yarn Y. The yarn detecting section 6 irradiates the
spun yarn Y with a light emitting diode as a light source, and detects
the defective part of the spun yarn Y and the yarn breakage of the
spun yarn Y based on a reflected light quantity from the spun yarn
Y. Specifically, the control section analyzes a detection signal
from the yarn detecting section 6 to determine presence or absence
of the defective part and presence or absence of the yarn breakage.
As the yarn detecting section 6, a capacitance sensor and the like
may be employed in addition to an optical sensor described above.
The traversing section 7 traverses the spun yarn Y guided to
a package PK. The traversing section 7 mainly includes a traverse
guide 71 and a traverse guide driving unit. The traverse guide 71
reciprocates in a rotation axis direction of a bobbin TB with the
spun yarn Y hooked to a hook portion to traverse the spun yarn Y.
The traverse guide driving unit drives the traverse guide 71 by
using power of a servo motor. The traversing section 7 thus
configures a so-called arm-type traverse device adapted to traverse
the spun yarn Y by the reciprocating traverse guide 71. However,
7/19
a belt-type traverse device, a blade traverse device, and the like
can be used in addition to the arm-type traverse device. The winding
device 100 may employ a traverse drum method, i.e., a structure
in which a drum that rotates while making contact with the package
PK is arranged to traverse the spun yarn Y by a guiding groove formed
on a surface of the drum.
The winding section 8 winds the spun yarn Y by rotating the
bobbin TB. The winding section 8 mainly includes a bobbin holding
unit 81, a contact roller 82, and a package driving unit. The bobbin
holding unit 81 includes a bearing for removably clamping the bobbin
TB, and rotatably holds the bobbin TB. The contact roller 82 adjusts
the shape of the package PK by pressing the surface of the package
PK. The package driving unit rotates the bobbin TB and the package
PK formed on the bobbin TB by using the power of the servo motor.
The winding section 8 is configured such that the package PK is
rotated by the package driving unit, and the contact roller 82 is
rotated accompanying the rotation of the package PK. However, the
contact roller 82 may be rotated by the package driving unit, and
the package PK may be rotated accompanying the rotation of the
contact roller 82.
The bobbin supplying section 9 supplies the yarn supplying
bobbin SB to the bobbin supporting section 1. The bobbin supplying
section 9 is mainly configured by a magazine 91, a guiding passage
92, and an open/close mechanism 93. A structure of the bobbin
supplying section 9 will be described in detail below.
FIG. 2 is a view illustrating the bobbin supplying section
9. FIG. 3 is a view of the bobbin supplying section 9 seen from
the direction of an arrow X. The arrows in the figures indicate
a rotating direction of the magazine 91 (see FIG. 3) and a guiding
direction of the yarn supplying bobbin SB (see FIG. 2).
The magazine 91 is provided with a plurality of through-holes
91H in a circumferential direction with a rotation axis A of the
magazine 91 as a center. Therefore, the magazine 91 can accommodate
the yarn supplying bobbin SB in each through-hole 91H. More
8/19
specifically, the yarn supplying bobbin SB inserted to each
through-hole 91H is supported by the open/close mechanism 93, and
held inside the through-hole 91H. The magazine 91 can
intermittently rotate so that the through-hole 91H stops at a
predetermined position. The predetermined position is a position
where the through-hole 91H overlaps a cutout portion 931L. The
cutout portion 931L refers to an empty portion where a plate member
931 is not arranged.
The guiding passage 92 is formed to extend one through-hole
91H to the bobbin supporting section 1. Therefore, the guiding
passage 92 can guide the yarn supplying bobbin SB accommodated in
the through-hole 91H to the bobbin supporting section 1. More
specifically, the yarn supplying bobbin SB accommodated in the
through-hole 91H is guided by the guiding passage 92 when dropped
from the through-hole 91H, and then guided to the bobbin supporting
section 1. The yarn supplying bobbin SB is supported by inserting
a peg 11 to the yarn supplying bobbin SB.
The open/close mechanism 93 is configured by the plate member
931 arranged to block a lower opening of the through-hole 91H and
an open/close member 932. In the present embodiment, the
open/close member 932 is a shutter member (hereinafter indicated
as the shutter member 932). The plate member 931 is provided with
the cutout portion 931L that communicates one of the through-holes
91H with the guiding passage 92. The shutter member 932 can open
or close the cutout portion 931L by moving in parallel to the plate
member 931. Therefore, the plate member 931 can support the yarn
supplying bobbin SB inserted to the through-hole 91H. The shutter
member 932 can support the yarn supplying bobbin SB inserted to
the through-hole 91H when closing the cutout portion 931L. The
shutter member 932 can drop the yarn supplying bobbin SB
accommodated in the through-hole 91H by opening the cutout portion
931L. More specifically, the plate member 931 can support the yarn
supplying bobbins SB inserted to the other through-holes 91H
excluding the through-hole 91H that stopped above the cutout portion
9/19
931L. The shutter member 932 can support the yarn supplying bobbin
SB inserted to the through-hole 91H that stopped above the cutout
portion 931L when closing the cutout portion 931L. The shutter
member 932 can drop the yarn supplying bobbin SB accommodated in
the through-hole 91H that stopped above the cutout portion 931L
by opening the cutout portion 931L.
As described above, since the bobbin supplying section 9 of
the winding device 100 includes the open/close mechanism 93 for
communicating or blocking the guiding passage 92 and the
through-hole 91H on which the plate member 931 is not arranged,
the yarn supplying bobbins SB can be inserted to all the
through-holes 91H. That is, the yarn supplying bobbin SB can be
inserted to all the through-holes 91H by closing the cutout portion
931L with the shutter member 932. The inserting operation of the
yarn supplying bobbin SB by an operator is thus simplified. The
frequency of the inserting operation can also be reduced.
As described above, the open/close mechanism 93 is configured
by the plate member 931, which is provided with the cutout portion
931L for communicating one of the through-holes 91H and the guiding
passage 92, and the shutter member 932 for opening or closing the
cutout portion 931L. The open/close mechanism 93 can be moved by
a driving device 94 adapted to rotate the magazine 91 (see FIGS.
4 and 5) .
The open/close mechanism 93 is thus configured by the plate
member 931 provided with the cutout portion 931L and the shutter
member 932 for opening or closing the cutout portion 931L, and is
movable by the driving device 94 adapted to rotate the magazine
91. Therefore, the operation of the magazine 91 and the operation
of the open/close mechanism 93 can be performed in conjunction with
each other.
Furthermore, the shutter member 932 is configured to move
parallel to the plate member 931, as described above.
Since the shutter member 932 moves parallel to the plate
member 931, the open/close mechanism 93 can be miniaturized. That
10 /19
is, since the shutter member 932 moves parallel to the plate member
931, a movable region of the shutter member 932 is small and the
open/close mechanism 93 can be miniaturized. Therefore, the
miniaturization of the bobbin supplying section 9 can be realized,
and furthermore, the miniaturization of the winding device 100 can
be achieved.
The open/close mechanism 93 is movable by the driving device
94 adapted to rotate the magazine 91, as described above. The
driving device 94 is mainly configured by a magazine gear 941, a
feeding lever 942, a feeding claw 943, and a stop latch 944 (see
FIG. 4). A structure in which the open/close mechanism 93 is movable
by the driving device 94 will be hereinafter described in detail.
FIG. 4 is a view illustrating a structure of the open/close
mechanism 93 and the driving device 94. FIGS. 5A to 5C are views
illustrating an operation mode of the open/close mechanism 93 and
the driving device 94. The arrows in the figure indicate the
operating direction of each component constituting the open/close
mechanism 93 and the driving device 94.
The magazine gear 941 rotates the magazine 91. The magazine
gear 941 is provided with a feeding gear Ga, to which the feeding
claw 943 is hooked, and a stop gear Gb, to which the stop latch
944 is hooked. The feeding gear Ga has nine gear teeth in which
the distance from the rotation axis A to the outer circumferential
surface gradually becomes smaller with change in an angular phase
in the rotating direction. The stop gear Gb has nine gear teeth
in which the distance from the rotation axis A to the outer
circumferential surface gradually becomes larger with change in
the angular phase in the rotating direction. The feeding gear Ga
and the stop gear Gb each have nine gear teeth because nine
through-holes 91H are formed in the magazine 91.
The feeding lever 942 is swingably attached with the rotation
axis A as the center. The feeding lever 942 is provided with a
supporting shaft SH1 for swingably supporting the feeding claw 943,
and a pin P for pushing a roller arm 945. Furthermore, the shutter
11 /19
member 932 is attached to the feeding lever 942 so that the shutter
member 932 can be moved (turned). In the present embodiment, the
shutter member 932 opens the cutout portion 931L when the feeding
lever 942 is swung to one side (see FIG. SA). However, the shutter
member 932 closes the cutout portion 931L when the feeding lever
942 is swung to the other side (see FIGS. 5B and 5C) .
The feeding claw 943 rotates the magazine gear 941 to one side
by the swinging of the feeding lever 942. The feeding claw 943 is
provided with a claw portion that is hooked to the feeding gear
Ga. When the feeding lever 942 is swung to one side
(counterclockwise direction in FIG. 4), the feeding claw 943 does
not rotate the magazine gear 941 since the claw portion is not hooked
to the feeding gear Ga (see FIG. SA). However, when the feeding
lever 942 is swung to the other side (clockwise direction in FIG.
4), the feeding claw 943 rotates the magazine gear 941 since the
claw portion is hooked to the feeding gear Ga (see FIGS. 5B, 5C).
The stop latch 944 causes the magazine gear 941 to be freely
rotatable or non-rotatable by the swinging of the feeding lever
942. The stop latch 944 is provided with a claw portion that is
hooked to the stop gear Gb. The stop latch 944 is swingably
supported with a supporting shaft SH2 provided in the roller arm
945 as a center. The roller arm 945 and the stop latch 944 are
configured to be swingable with each other within a prescribed
opening angle. When the feeding lever 942 is swung to one side,
the stop latch 944 causes the magazine gear 941 to be non-rotatable
since the roller arm 945 is swung when the pin P pushes the roller
arm 945 so that the claw portion is not detached from the stop gear
Gb (see FIG. SA). However, when the feeding lever 942 is swung to
other side, the stop latch 944 causes the magazine gear 941 to be
freely rotatable since the claw portion is detached from the stop
gear Gb when the pin P pushes the roller arm 945 (see FIG. 5B).
When the feeding lever 942 is further swung, the stop latch 944
causes the magazine gear 941 to be non-rotatable since the claw
portion is hooked to the stop gear Gb when the pin P separates from
12/19
the roller arm 945 (see FIG. 5C).
The operation mode of the open/close mechanism 93 and the
driving device 94 will be described along the time series. This
is the operation carried out when supplying the yarn supplying
bobbin SB to the bobbin supporting section 1.
First, as illustrated in FIG. 5A, the feeding lever 942 is
swung to one side. In this case, the pin P swings the roller arm
945 towards the stop latch 944, but the stop latch 944 causes the
magazine gear 941 to be non-rotatable since the claw portion is
not detached from the stop gear Gb. The feeding claw 943 cannot
rotate the magazine gear 941 because it is swung in a direction
in which the claw portion is not hooked to the feeding gear Ga.
Therefore, the claw portion of the feeding claw 943 slides on the
outer peripheral surface of the gear tooth and moves to the adjacent
gear tooth. The shutter member 932 moves (turns) by the swinging
of the feeding lever 942, and opens the cutout portion 931L. The
yarn supplying bobbin SB supported by the shutter member 932 thus
can be dropped.
Then, the feeding lever 942 is swung to the other side, as
illustrated in FIG. 5B. In this case, the pin P swings the roller
arm 945 to the opposite side of the stop latch 944, so that the
stop latch 944 causes the magazine gear 941 to freely rotate since
the stop latch 944 swings along with the roller arm 945 and the
claw portion is detached from the stop gear Gb. The feeding claw
943 can rotate the magazine gear 941 since the claw portion is hooked
to the feeding gear Ga. Therefore, the magazine 91 rotates
integrally with the magazine gear 941. The shutter member 932 moves
(turns) along with the feeding lever 942, and closes the cutout
portion 931L.
Next, the feeding lever 942 is further swung, as illustrated
in FIG. 5C. In this case, the stop latch 944 causes the magazine
gear 941 to freely rotate since the claw portion is detached from
the stop gear Gb. Therefore, the claw portion of the stop latch
944 slides on the outer peripheral surface of the gear tooth and
13/19
moves to the adjacent gear tooth. The feeding claw 943 further
rotates the magazine gear 941 since the claw portion is hooked to
the feeding gear Ga. Therefore, the magazine 91 further rotates
integrally with the magazine gear 941, and the adjacent through-hole
91H stops above the cutout portion 931L. The yarn supplying bobbin
SB accommodated in the adjacent through-hole 91H is thereby
supported by the shutter member 932.
Therefore, since the shutter member 932 of the open/close
mechanism 93 is movable by the driving device 94 that rotates the
magazine 91, the bobbin supplying section 9 of the winding device
100 can easily perform the operation of the magazine 91 and the
operation of the open/close mechanism 93 in conjunction with each
other.
The feeding lever 942 is swung by using power of a stepping
motor (not illustrated) arranged in the driving device 94.
Thus, since the feeding lever 942 is swung by using the power
of the stepping motor, the bobbin supplying section 9 can prevent
failure of the open/close mechanism 93 and the driving device 94
even when the yarn supplying bobbin SB is stuck between the shutter
member 932 and the plate member 931, and the like. This is because
even if the yarn supplying bobbin SB is stuck or the spun yarn Y
wound around the yarn supplying bobbin SB gets entangled, for
example, and a strong load is applied on the open/close mechanism
93 and the driving device 94, the load can be released by shifting
the phase of the rotor (step out phenomenon).
The feeding lever 942 may be swung by a dedicated power source
for driving the bobbin supplying section 9. That is, the bobbin
supplying section 9 may include a dedicated power source adapted
to rotate the magazine 91, and the feeding lever 942 may be swung
by the relevant power source.
When configured in such a manner, the feeding lever 942 is
swung by the dedicated power source for driving the bobbin supplying
section 9, and thus bobbin replacement of high degree of freedom
that is not influenced by the operation of other main body mechanisms
14/19
can be realized.
The bobbin supplying section 9 of the winding device 100 has
a characteristic in that it can detect whether or not the shutter
member 932 is supporting the yarn supplying bobbin SB. A structure
for detecting whether or not the shutter member 932 is supporting
the yarn supplying bobbin SB will be hereinafter described in
detail.
FIG. 6 is a view illustrating a state in which the shutter
member 932 is supporting the yarn supplying bobbin SB. The arrow
in the figure indicates a pushing direction of the shutter member
932 by the yarn supplying bobbin SB.
The open/close mechanism 93 includes a detection device 933
in proximity to the shutter member 932. The detection device 933
is a magnetic force sensor (Hall Ie) adapted to detect magnetic
force of a magnet M attached to the shutter member 932. The
detection device 933 converts an output voltage according to the
change in a magnetic flux density, and detects the position of the
magnet M from the value of the output voltage.
The shutter member 932 is attached to the feeding lever 942
by way of an urging member such as a coil spring. The shutter member
932 is thus pushed by the yarn supplying bobbin SB when the yarn
supplying bobbin SB is inserted. The control section thus can grasp
whether or not the shutter member 932 is being pushed based on a
detection signal from the detection device 933.
Since the open/close mechanism 93 can detect whether or not
the shutter member 932 is supporting the yarn supplying bobbin SB,
the stopping of the operation of the winding device 100 that occurs
when the yarn supplying bobbin SB is not inserted to the magazine
91 can be prevented.
As described above, the winding device 100 has an effect of
simplifying the inserting operation of the yarn supplying bobbin
SB and reducing the frequency of the inserting operation. Such an
effect can be enhanced by configuring an automatic winder that
includes a plurality of the winding devices 100.
15/19
In other words, the effect of simplifying the inserting
operation of the yarn supplying bobbin SB by the operator can be
enhanced by arranging a plurality of the winding devices 100. The
effect of reducing the frequency of the inserting operation is also
enhanced.
