Field of the Invention
[0001] One aspect of the present invention relates
to a yarn winding system.
2. Description of the Related Art
[0002] There is known a yarn winding system
including: a spinning machine provided with a plurality
of spinning units that generate a yarn and wind the
yarn around a bobbin to form a yarn supplying bobbin; a
yarn winding machine provided with a plurality of
winding units that unwind a yarn from the yarn
supplying bobbin and wind the yarn into a package; and
a conveying device that conveys the yarn supplying
bobbin from the spinning machine to the yarn winding
machine and conveys a used yarn supplying bobbin from
the yarn winding machine to the spinning machine.
[0003] One example of such a yarn winding system
is disclosed in JP H6-191734 A. JP H6-191734 A
discloses that a spinning cop (yarn supplying bobbin)
formed in a plurality of spinning frames (spinning
machines) is conveyed to one yarn winding machine
3
(bobbin machine), and a cross winding bobbin (package)
is formed in the one yarn winding machine.
[0004] In recent years, there has been a demand
for improving a manufacturing capability of a package
in a yarn winding machine in accordance with an
improvement in a manufacturing capability of a yarn
supplying bobbin in a spinning machine. Therefore, it
is conceivable to improve the manufacturing capability
by increasing a number of winding units of the yarn
winding machine included in the conventional yarn
winding system described above. However, in
consideration of a conveyance capability of a yarn
supplying bobbin in the yarn winding machine or a
suction capability of a blower provided in the yarn
winding machine, it is not possible cope with by simply
increasing a number of winding units provided in the
yarn winding machine. In addition to the demand
described above, there is a demand for reducing a
possibility that an operation of a yarn winding system
is completely stopped even when a trouble occurs in a
yarn winding machine for some reason.
BRIEF SUMMARY OF THE INVENTION
[0005] Accordingly, an object of one aspect of the
4
present invention is to provide a yarn winding system
that can improve a manufacturing capability of a
package and reduce a possibility that an operation of
the yarn winding system is completely stopped.
[0006] A yarn winding system according to one
aspect of the present invention includes: one spinning
machine in which a plurality of spinning units that
form a yarn supplying bobbin with a yarn wound on a
bobbin are arranged in one direction; a plurality of
yarn winding machines having a plurality of winding
units that wind a yarn from the yarn supplying bobbin
to form a package; and a conveying device that conveys
the yarn supplying bobbin formed in the one spinning
machine to the yarn winding machine, and conveys a used
yarn supplying bobbin used in the yarn winding machine
to the one spinning machine. The plurality of yarn
winding machines are arranged on a side of at least one
end part of the one spinning machine in an arrangement
direction of the spinning units, in a direction
orthogonal to the arrangement direction, and the
conveying device conveys the yarn supplying bobbin from
the one spinning machine to each of the plurality of
yarn winding machines without passing through another
yarn winding machine.
5
[0007] Note that a plurality of definitions can be
made for the one yarn winding machine mentioned here.
For example, the one yarn winding machine can be
defined as a configuration having: one winding machine
control device; and a plurality of winding units under
control of the one yarn winding machine control device.
Further, for example, the one yarn winding machine can
also be defined as a configuration having one blower
and a plurality of winding units connected to the
blower. In addition, a definition of the one spinning
machine can similarly be defined as a configuration
having: one winding machine control device; and a
plurality of spinning units under control of the one
yarn winding machine control device. Further, for
example, the one spinning machine can also be defined
as a configuration having one blower and a plurality of
spinning units connected to the blower.
[0008] In the yarn winding system having this
configuration, one spinning machine and a plurality of
yarn winding machines are arranged on a side of at
least one end part of one spinning machine in an
arrangement direction of the spinning units, in a
direction orthogonal to the arrangement direction.
Therefore, a plurality of yarn winding machines can be
6
connected to one spinning machine without complicating
a configuration of the conveying device. Furthermore,
in the yarn winding system having this configuration,
since a plurality of yarn winding machines are provided
for one spinning machine, a manufacturing capability of
the package can be improved without largely changing a
configuration of the conventional yarn winding machine,
such as increasing an output of the blower. Further,
in the yarn winding system having this configuration,
the yarn supplying bobbin is conveyed from one spinning
machine to each of the plurality of yarn winding
machines without passing through another yarn winding
machine. Therefore, there is no such a problem that
the yarn supplying bobbin is not supplied to a winding
unit arranged at a position far from a machine inlet of
the yarn winding machine. Thus, the yarn winding
system according to one aspect of the present invention
can improve a manufacturing capability of the package,
and reduce a possibility that an operation of the yarn
winding system is completely stopped.
[0009] In a yarn winding system according to one
aspect of the present invention, a plurality of
spinning units may include a spinning unit belonging to
a first group and a spinning unit belonging to a second
7
group including a spinning unit without belonging to
the first group, and a conveying device may convey a
yarn supplying bobbin from a spinning unit belonging to
the first group to one of the two yarn winding machines,
convey a used yarn supplying bobbin from the one of the
yarn winding machines to the spinning unit belonging to
the first group, convey a yarn supplying bobbin from a
spinning unit belonging to the second group to another
of the two yarn winding machines, and convey a used
yarn supplying bobbin from another of the yarn winding
machines to a spinning unit belonging to the second
group. This configuration makes it possible to improve
a manufacturing capability of a package without greatly
changing a configuration of a conveyance unit in the
conventional spinning machine, and to reduce a
possibility that an operation of the yarn winding
system is completely stopped.
[0010] In a yarn winding system according to one
aspect of the present invention, a winding machine
control device provided in each of the two yarn winding
machines may be arranged at an end part opposite to a
side where one spinning machine is arranged, and a
display operation unit provided in the winding machine
control device may be provided such that a display
8
operation surface is orthogonal to an arrangement
direction. This configuration enables display
operation units provided in the winding machine control
device to be brought closer to each other. This allows
a worker to operate and monitor the two yarn winding
machines without a large movement.
[0011] In a yarn winding system according to one
aspect of the present invention, two yarn winding
machines may be arranged adjacent to each other, and
the two yarn winding machines may be arranged such that
back surfaces are facing each other when a side where a
yarn path is to be arranged when a yarn of the yarn
supplying bobbin is wound in the yarn winding machine
is a front surface, and a side opposite to the side
where the yarn path is to be arranged is a back surface.
This configuration enables the yarn winding system to
be arranged in a small space.
[0012] In a yarn winding system according to one
aspect of the present invention, a conveying device may
form a first closed loop conveyance path between a
spinning unit belonging to the first group and one of
the two yarn winding machines, and may form a second
closed loop conveyance path between a spinning unit
belonging to the second group and another of the two
9
yarn winding machines. This configuration makes it
possible to improve a manufacturing capability of a
package without greatly changing a configuration of a
conveyance unit in the conventional spinning machine,
and to reduce a possibility that an operation of the
yarn winding system is completely stopped.
[0013] In a yarn winding system according to one
aspect of the present invention, a conveying device may
be connected from one spinning machine to each of a
plurality of yarn winding machines via a branch part
that branches a conveyance path, and connected from
each of the plurality of yarn winding machines to one
spinning machine via a merging part that merges
conveying paths. This configuration makes it possible
to, with a simple configuration, convey a yarn
supplying bobbin from one spinning machine to each of
the plurality of yarn winding machines without passing
through another yarn winding machine.
[0014] In a yarn winding system according to one
aspect of the present invention, a first storage unit
that temporarily stores a yarn supplying bobbin
conveyed from one spinning machine and adjusts a supply
timing of the yarn supplying bobbin to a yarn winding
machine may be provided for at least one of a plurality
10
of yarn winding machines. This configuration makes it
possible to stably supply a yarn supplying bobbin
without stopping an operation of the spinning machine,
even if the yarn supplying bobbin is excessively
supplied from the spinning machine to the yarn winding
machine.
[0015] In a yarn winding system according to one
aspect of the present invention, a first storage unit
may be provided for each of a plurality of yarn winding
machines. In the yarn winding system having this
configuration, it is possible to more stably supply a
yarn supplying bobbin from a spinning machine to the
yarn winding machine.
[0016] In a yarn winding system according to one
aspect of the present invention, a second storage unit
that temporarily stores a used yarn supplying bobbin
conveyed from a yarn winding machine and adjusts a
supply timing of the used yarn supplying bobbin to one
spinning machine may be provided for at least one of a
plurality of yarn winding machines. This configuration
makes it possible to stably supply the used yarn
supplying bobbin without stopping an operation of the
yarn winding machine, even if the used yarn supplying
bobbin is excessively supplied from the yarn winding
11
machine to the spinning machine.
[0017] In a yarn winding system according to one
aspect of the present invention, a second storage unit
may be provided for each of a plurality of yarn winding
machines. In the yarn winding system having this
configuration, it is possible to more stably supply a
used yarn supplying bobbin from the yarn winding
machine to a spinning machine.
[0018] A conveying device of a yarn winding system
according to one aspect of the present invention may
include a mixed conveyance unit connected with a
machine outlet where a yarn supplying bobbin is carried
out from one spinning machine, a machine inlet where a
used yarn supplying bobbin is carried into one spinning
machine, a machine inlet where the yarn supplying
bobbin is carried into each of a plurality of yarn
winding machines, and a machine outlet where the used
yarn supplying bobbin is carried out from each of the
plurality of yarn winding machines. The mixed
conveyance unit may convey the yarn supplying bobbin
and the used yarn supplying bobbin in a mixed state.
This configuration makes it possible to, with a simple
configuration, convey a yarn supplying bobbin from one
spinning machine to each of the plurality of yarn
12
winding machines without passing through another yarn
winding machine.
[0019] According to one aspect of the present
invention, it is possible to improve a manufacturing
capability of the package, and reduce a possibility
that an operation of the yarn winding system is
completely stopped.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0021] Hereinafter, an embodiment will be
described with reference to the drawings. In the
description of the drawings, the same elements are
denoted by the same reference numerals, and redundant
descriptions are omitted. In FIGS. 1, 2, and 6 to 9,
an X axis, a Y axis, and a Z axis that are orthogonal
to each other are set for convenience of description.
Further, in the following description, as illustrated
in FIG. 1, when a yarn winding system 1 is viewed from
a front surface (Y-axis direction), a front side may be
referred to as front, a rear side as rear, a left side
as left, and a right side as right. That is, the Yaxis direction may be referred to as a front-rear
direction, an X-axis direction as a left-right

direction.
14
[0022] As illustrated in FIGS. 1 and 2, the yarn
winding system 1 includes one spinning machine 3, two
(a plurality of) automatic winders (yarn winding
machines) 4 and 4, and a conveying device 5. In the
yarn winding system 1 of the present embodiment, a
larger number of automatic winders 4 than a number of
the spinning machines 3 are connected by the conveying
device 5.
[0023] The spinning machine 3 generates a yarn Y2
from a roving yarn Y1, winds the yarn Y2 around a
bobbin B, and forms a yarn supplying bobbin 11 (see FIG.
5(c)). A roving bobbin 10 used in the spinning machine
3 is supplied from a roving frame (not illustrated) or
the like that generates the roving yarn Y1 from a
sliver and winds the roving yarn Y1 around a bobbin B0
(see FIG. 3) to form the roving bobbin 10.
[0024] The spinning machine 3 includes a machine
control device 31 that controls an operation of the
spinning machine 3, and a plurality of spinning units
32 that form the yarn supplying bobbin 11. The machine
control device 31 has a display unit 31a such as a
display and an operation unit 31b such as an input key.
The display unit 31a displays an operation status and
the like of each spinning unit 32. The operation unit
15
31b is a part where an operator performs setting or the
like of operating conditions of each spinning unit 32.
[0025] As illustrated in FIG. 3, each of the
plurality of spinning units 32 has a roving yarn supply
unit 36, a draft device 33, and a twisting device 34.
The plurality of spinning units 32 are arranged along
one direction. Hereinafter, the direction in which the
plurality of spinning units 32 are arranged is referred
to as an arrangement direction D1. In the spinning
machine 3 of the present embodiment, a plurality of
spinning units 32 are arranged in the arrangement
direction D1 on each of a front side and a rear side of
the entire machine.
[0026] The roving yarn supply unit 36 supports the
roving bobbin 10 in which the roving yarn Y1 is wound
around the bobbin B0. The draft device 33 includes a
pair of back rollers 331, a pair of middle rollers 332,
and a pair of front rollers 333. In the draft device
33, the roving yarn Y1 unwound from the roving bobbin
10 is drafted by rotation of the pair of back rollers
331, the pair of middle rollers 332, and the pair of
front rollers 333 at a predetermined speed ratio.
[0027] The pair of back rollers 331 have a bottom
roller 331a and a top roller 331b, and are arranged so
16
as to face each other with a travelling path of the
roving yarn Y1 interposed in between. The bottom
roller 331a is connected with a first drive motor 331c
via an output shaft (not illustrated) arranged over the
plurality of spinning units. The pair of middle
rollers 332 have a bottom roller 332a and a top roller
332b, and are arranged so as to face each other with a
travelling path of the roving yarn Y1 interposed in
between. On each of the bottom roller 332a and the top
roller 332b, an apron belt is laid. The bottom roller
332a is connected with a second drive motor 332c via an
output shaft (not illustrated) arranged over the
plurality of spinning units. The pair of front rollers
333 have a bottom roller 333a and a top roller 333b,
and are arranged so as to face each other with a
travelling path of the roving yarn Y1 interposed in
between. The bottom roller 333a is connected with a
third drive motor 333c via an output shaft (not
illustrated) arranged over the plurality of spinning
units.
[0028] An example of the first drive motor 331c,
the second drive motor 332c, and the third drive motor
333c is a servo motor. Each of the first drive motor
331c, the second drive motor 332c, and the third drive
17
motor 333c has a rotary encoder (not illustrated), and
is independently controlled by the machine control
device 31 via a servo motor drive circuit and a servo
driver.
[0029] The twisting device 34 has a spindle shaft
341, a ring rail 342, a ring 343, and a traveler 344.
The spindle shaft 341 holds a bottom part Ba of the
bobbin B with a top part Bb of the bobbin B facing
upward, and rotates the bobbin B. The ring rail 342 is
movable in an axial direction of the bobbin B. The
ring 343 is fixed to the ring rail 342. The traveler
344 is supported by the ring 343 and is movable along
the ring 343.
[0030] In the twisting device 34, the roving yarn
Y1 drafted in the draft device 33 is inserted into a
gap between the ring 343 and the traveler 344, and an
end part of the roving yarn Y1 is fixed to the bobbin B.
When the spindle shaft 341 rotates the bobbin B in this
state, the traveler 344 moves along the ring 343 so as
to be pulled by the roving yarn Y1. At this time, the
ring rail 342 gradually moves from the bottom part Ba
side to the top part Bb side while reciprocating within
a predetermined range along the axial direction of the
bobbin B. In the twisting device 34, a rotation of the
18
traveler 344 is delayed from a rotation of the bobbin B,
so that the roving yarn Y1 is twisted to generate the
yarn Y2, and the yarn Y2 is wound around the bobbin B
to form the yarn supplying bobbin 11.
[0031] The spinning machine 3 having the plurality
of spinning units 32 configured as described above is
configured as a so-called simultaneous doffing type.
That is, the spinning machine 3 stocks a plurality of
empty bobbins 13 conveyed from the automatic winder 4
by the conveying device 5, sets the empty bobbins 13 in
each spinning unit 32 all at once, and winds the yarn
all at once. When the winding of the yarn is completed
in each spinning unit 32 and the yarn supplying bobbin
11 is formed, the spinning machine 3 simultaneously
doffs all the yarn supplying bobbins 11. In the
meantime, the spinning machine 3 pulls out the stocked
empty bobbin 13 from a tray 9 (described in detail in a
later stage) and sets the empty bobbin 13 in each of
the spinning units 32 all at once, and instead, sets
the doffed yarn supplying bobbin 11 in the tray 9 all
at once.
[0032] The automatic winder 4 winds the yarn Y2
from the yarn supplying bobbin 11 to form a package 15.
As illustrated in FIGS. 1 and 2, the automatic winder 4
19
includes a winding machine control device 41 that
controls an operation of the automatic winder 4, and a
plurality of winding units 42 that form the package 15.
[0033] In the present embodiment, as shown in FIG.
2, the two automatic winders 4 and 4 are arranged on a
side of one end of one spinning machine 3 in the
arrangement direction D1, in a direction orthogonal to
the arrangement direction D1 (Y-axis direction).
Hereinafter, the direction orthogonal to the
arrangement direction D1, that is, the arrangement
direction of the two automatic winders 4 and 4 may be
referred to as "installation direction D2". In
addition, the two automatic winders 4 and 4 may simply
be arranged such that the arrangement directions are
overlapped when viewed in the "installation direction
D2", and even if the two automatic winders 4 and 4 are
displaced in the X-axis direction, they are arranged in
a direction orthogonal to the arrangement direction D1.
The arrangement direction D1 of the plurality of
spinning units 32 and the arrangement direction of the
plurality of winding units 42 are coincide in that both
are along the X-axis direction. Hereinafter, the
automatic winder 4 arranged on a front side in the
front-rear direction in the installation direction D2
20
may be referred to as "front automatic winder 4A", and
the automatic winder 4 arranged on a rear side in the
front-rear direction in the installation direction D2
may be referred to as "rear automatic winder 4B".
[0034] The winding machine control device 41 has a
display unit (display operation unit) 41a such as a
display, and an operation unit (display operation unit)
41b such as an input key. The display unit 41a
displays an operation status and the like of each
winding unit 42. The operation unit 41b is a part
where an operator performs setting or the like of
operating conditions of each winding unit 42. Note
that the winding machine control device 41 also
controls an operation of the conveying device 5
described in detail in a later stage.
[0035] As illustrated in FIG. 4, each of the
plurality of winding units 42 includes a winding device
43, a tension applying device 44, a yarn monitoring
device 45, an upper yarn catching device 46, a lower
yarn catching device 47, a yarn joining device 48, and
a unit control section 49.
[0036] The winding device 43 has a cradle 43a and
a winding drum 43b. The cradle 43a supports the
package 15. The winding drum 43b rotates the package
21
15 while traversing the yarn Y2. This causes the yarn
Y2 to be wound from the yarn supplying bobbin 11 set at
a predetermined position, to form the package 15. The
tension applying device 44 applies a predetermined
tension to the yarn Y2 travelling from the yarn
supplying bobbin 11 to the package 15.
[0037] The yarn monitoring device 45 monitors the
travelling yarn Y2 in order to detect a yarn defect
(thickness abnormality of the yarn Y2, mixing of
foreign substance into the yarn Y2, and the like).
When a yarn defect is detected, the yarn Y2 is cut by a
cutter that is provided separately. When the yarn Y2
is cut, the upper yarn catching device 46 catches a
yarn end of the yarn Y2 on the package 15 side and
guides the yarn end to the yarn joining device 48.
When the yarn Y2 is cut, the lower yarn catching device
47 catches a yarn end of the yarn Y2 on the yarn
supplying bobbin 11 side and guides the yarn end to the
yarn joining device 48. The yarn joining device 48
connects the yarn ends guided by the upper yarn
catching device 46 and the lower yarn catching device
47.
[0038] The unit control section 49 controls, in
the winding unit 42, operations of the winding device
22
43, the tension applying device 44, the yarn monitoring
device 45, the upper yarn catching device 46, the lower
yarn catching device 47, and the yarn joining device 48.
For example, the unit control section 49 applies cut
processing on a thick yarn portion in the yarn
supplying bobbin 11 on the basis of information
acquired by the yarn monitoring device 45, and controls
the yarn joining device 48 to connect a yarn end of the
yarn Y2 on the yarn supplying bobbin 11 side subjected
to the cut processing and a yarn end of the yarn Y2 on
the package 15 side.
[0039] The winding machine control device 41
provided in each of the two automatic winders 4 (4A,
4B) is arranged at an end part opposite to a side on
which one spinning machine 3 is arranged. In the
present embodiment, the winding machine control device
41 is arranged at a machine right end part of the
automatic winder 4. The display unit 41a and the
operation unit 41b provided in the winding machine
control device 41 are provided such that a display
operation surface is orthogonal to the arrangement
direction D1. In the present embodiment, the display
operation surfaces of the display unit 41a and the
operation unit 41b are directed to the right.
23
[0040] Further, the two automatic winders 4 (4A,
4B) are arranged adjacent in the installation direction
D2. Specifically, when a side where a yarn path is to
be arranged when the yarn Y2 of the yarn supplying
bobbin 11 is wound in the winding unit 42 is a front
surface, and a side opposite to the side where the yarn
path is to be arranged is a back surface, the two
automatic winders 4 and 4 are arranged such that back
surfaces are facing each other.
[0041] The conveying device 5 conveys the yarn
supplying bobbin 11 formed in one spinning machine 3 to
each of the two automatic winders 4 and 4, and conveys
the empty bobbin 13, which is a used yarn supplying
bobbin 11 used in each of the two automatic winders 4
and 4, to the spinning machine 3. Note that the empty
bobbin 13 mentioned here includes a bobbin B in a state
where the yarn Y2 is not wound, and a bobbin (defective
bobbin) in which the yarn Y2 is wound around the bobbin
B, but a winding amount is smaller than that of a
bobbin B (a full yarn supplying bobbin 11) in which a
predetermined amount of the yarn Y2 is wound to be
supplied from the spinning machine 3.
[0042] The conveying device 5 conveys each of the
yarn supplying bobbin 11 and the empty bobbin 13 in a
24
state of being placed on the tray 9 as illustrated in
FIG. 5(a). The tray 9 has a disk-shaped base part 91,
a protrusion 92 protruding upward from the base part 91,
and a pin 93 protruding further upward from the
protrusion 92. The yarn supplying bobbin 11
illustrated in FIG. 5(c) (including a prepared yarn
supplying bobbin 11 illustrated in FIG. 5(d)) and the
empty bobbin 13 illustrated in FIG. 5(b) each are
inserted with the pin 93 at the bottom part Ba of the
bobbin B, to be mounted on the tray 9 with one end part
of the bobbin B facing upward. In other words, the
tray 9 is configured to allow the bobbin B to be placed
in an upright state where the axial direction of the
bobbin B is in a vertical direction.
[0043] As illustrated in FIG. 2, the conveying
device 5 includes a plurality of conveyance units (a
first conveyance unit 61 to a fifth conveyance unit 65)
as illustrated in a later stage. Each of the plurality
of conveyance units 61 to 65 can be appropriately
configured with a known configuration including: a
guide groove formed by a guide plate; a conveyor belt
or a round belt provided on a lower side of the guide
groove along the guide groove; a driving device that
drives the conveyor belt or round belt; and the like.
25
Each of the conveyance units 61 to 65 conveys the tray
9 on which the yarn supplying bobbin 11 and the empty
bobbin 13 are placed, by arranging the tray 9 in the
guide groove.
[0044] Next, a description is given to a
conveyance unit that conveys the yarn supplying bobbin
11 formed in one spinning machine 3 to the front
automatic winder 4A, and conveys the empty bobbin 13,
which is a used yarn supplying bobbin 11 used in the
front automatic winder 4A, to the spinning machine 3.
Such a conveyance unit is arranged along a conveying
direction of the yarn supplying bobbin 11 from the
spinning machine 3 to the front automatic winder 4A, in
an order of the first conveyance unit 61, the second
conveyance unit 62, and the third conveyance unit 63.
Further, along the conveying direction of the empty
bobbin 13 from the front automatic winder 4A to the
spinning machine 3, the fourth conveyance unit 64, the
fifth conveyance unit 65, and the first conveyance unit
61 are arranged in this order.
[0045] The first conveyance unit 61 is provided on
a lower side of the spinning units 32 arranged on a
machine front side of the spinning machine 3, along the
arrangement direction D1 of the spinning units 32. The
26
first conveyance unit 61 carries out, toward the front
automatic winder 4A, the yarn supplying bobbin 11
supplied to the first conveyance unit 61 in
simultaneous doffing of the spinning unit 32 arranged
on the machine front side of the spinning machine 3,
and carries in the empty bobbin 13 supplied from the
front automatic winder 4A, toward a lower side of the
spinning unit 32 arranged on the machine front side of
the spinning machine 3.
[0046] The second conveyance unit 62 is provided
between a machine outlet of the spinning machine 3 and
a machine inlet of the front automatic winder 4A. The
second conveyance unit 62 conveys the yarn supplying
bobbin 11 carried out from the spinning machine 3, to
the front automatic winder 4A. The second conveyance
unit 62 is provided with a pick finding device 51.
[0047] The pick finding device 51 pulls out a yarn
end Y21 of the yarn Y2 from the yarn supplying bobbin
11 conveyed to the front automatic winder 4A. Further,
the pick finding device 51 performs a process (a pick
finding process) of inserting the yarn end Y21 pulled
out from the yarn supplying bobbin 11, from the top
part Bb of the bobbin B into an internal part Bc of the
bobbin B, to form the prepared yarn supplying bobbin 11
27
as illustrated in FIG. 5(d). This allows the lower
yarn catching device 47 to catch the yarn end Y21 of
the yarn supplying bobbin 11 in each of the winding
units 42 of the front automatic winder 4A.
[0048] The third conveyance unit 63 is provided
along an arrangement direction of the winding units 42,
on a machine rear side of the front automatic winder 4A.
The third conveyance unit 63 conveys the yarn supplying
bobbin 11 from the machine inlet of the front automatic
winder 4A through the machine rear side, to a lower
side of each of the winding units 42.
[0049] The fourth conveyance unit 64 is provided
along an arrangement direction of the winding units 42,
on a machine front side of the front automatic winder
4A. The fourth conveyance unit 64 conveys the empty
bobbin 13 from each of the winding units 42 of the
front automatic winder 4A through the machine front
side, to a machine outlet (fifth conveyance unit 65) of
the front automatic winder 4A.
[0050] The fifth conveyance unit 65 is provided
between the machine outlet of the front automatic
winder 4A and a machine inlet (first conveyance unit
61) of the spinning machine 3. The fifth conveyance
unit 65 may be provided with a processing device (not
28
illustrated) that, when the yarn Y2 remains on the used
yarn supplying bobbin 11 discharged from the front
automatic winder 4A, removes the yarn Y2 to provide the
empty bobbin 13.
[0051] Note that the conveying device 5 may be
formed with a circulation path for circulation of the
yarn supplying bobbin 11 and the empty bobbin 13,
between the second conveyance unit 62 and the fifth
conveyance unit 65. The circulation path may convey,
to the fifth conveyance unit 65, the yarn supplying
bobbin 11 on which the pick finding process has been
unable to be executed or the pick finding process has
failed in the second conveyance unit 62, and remove the
bobbin B on which the yarn Y2 remains or the tray 9 on
which the bobbin B is not placed from the fifth
conveyance unit 65 and convey the tray 9 newly mounted
with the empty bobbin 13 to the second conveyance unit
62.
[0052] Next, a description is given to a
conveyance unit that conveys the yarn supplying bobbin
11 formed in one spinning machine 3 to the rear
automatic winder 4B, and conveys the empty bobbin 13
used in the rear automatic winder 4B to the spinning
machine 3. Such a conveyance unit is arranged, in a
29
conveying direction of the yarn supplying bobbin 11
from the spinning machine 3 to the rear automatic
winder 4B on the machine rear side, in an order of the
first conveyance unit 61, the second conveyance unit 62,
and the third conveyance unit 63. Further, in the
conveying direction of the empty bobbin 13 from the
rear automatic winder 4B to the spinning machine 3, the
fourth conveyance unit 64, the fifth conveyance unit 65,
and the first conveyance unit 61 are arranged in this
order. Note that the first conveyance unit 61 to the
fifth conveyance unit 65 are as described above, and
therefore a detailed description thereof will be
omitted.
[0053] In the spinning machine 3 of the present
embodiment, the plurality of spinning units 32 belong
to any one of two mutually different groups.
Specifically, the spinning machine 3 has the spinning
unit 32 (a spinning unit belonging to a first group)
arranged on a machine front side, and the spinning unit
32 (a spinning unit belonging to a second group)
arranged on a machine rear side. Each of the above two
groups is also a group of the spinning unit 32 in which
simultaneous doffing is performed.
[0054] The conveying device 5 forms a first closed
30
loop conveyance path between the spinning unit 32
belonging to the first group and one of the two
automatic winders 4A and 4B (automatic winder 4A), and
forms a second closed loop conveyance path between the
spinning unit 32 belonging to the second group and the
other of the two automatic winders 4A and 4B (automatic
winder 4B). Each of the first closed loop conveyance
path and the second closed loop conveyance path is
formed by the first conveyance unit 61, the second
conveyance unit 62, the third conveyance unit 63, the
fourth conveyance unit 64, and the fifth conveyance
unit 65.
[0055] As described above, the conveying device 5
conveys the yarn supplying bobbin 11 from the group of
spinning units 32 arranged on the machine front side of
the spinning machine 3 to the front automatic winder 4A,
and conveys the empty bobbin 13 from the front
automatic winder 4A to the group of spinning units 32
arranged on the machine front side of the spinning
machine 3. Further, the conveying device 5 conveys, to
the rear automatic winder 4B, the yarn supplying bobbin
11 from the group of the spinning units 32 arranged on
the machine rear side of the spinning machine 3, and
conveys the empty bobbin 13 from the rear automatic
31
winder 4B described above to the group of the spinning
units 32 arranged on the machine rear side of the
spinning machine 3.
[0056] Next, a description is given to an
operation of conveying the yarn supplying bobbin 11
formed in each of the spinning units 32 arranged on the
machine front side of the spinning machine 3. Each of
the spinning units 32 arranged on the machine front
side of the spinning machine 3 pulls out, from the tray
9, a plurality of empty bobbins 13 conveyed from the
front automatic winder 4A and stocked in the first
conveyance unit 61 to set the empty bobbins 13 all at
once, and starts winding of the yarn Y2 all at once.
When the winding of the yarn Y2 is completed in each
spinning unit 32 and the yarn supplying bobbin 11 is
formed, the spinning machine 3 simultaneously doffs all
the yarn supplying bobbins 11 arranged on the machine
front side of the spinning machine 3. In the meantime,
the spinning machine 3 pulls out, from the tray 9, the
empty bobbin 13 conveyed from the front automatic
winder 4A of the spinning machine 3 and stocked in the
first conveyance unit 61 to set the empty bobbin 13 to
each spinning unit 32 all at once again, and instead,
sets the doffed yarn supplying bobbins 11 on the tray 9
32
all at once.
[0057] The yarn supplying bobbins 11
simultaneously set on the tray 9 are conveyed to the
second conveyance unit 62. In the second conveyance
unit 62, the pick finding device 51 performs the pick
finding process of the yarn supplying bobbin 11. Then,
when the empty bobbin 13 is discharged from the winding
unit 42 in the front automatic winder 4A (when a supply
request signal to the front automatic winder 4A is
received), the second conveyance unit 62 carries out
the yarn supplying bobbin 11 subjected to the pick
finding process to the third conveyance unit 63, toward
the winding unit 42.
[0058] The third conveyance unit 63 into which the
yarn supplying bobbin 11 has been carried in from the
second conveyance unit 62 conveys the yarn supplying
bobbin 11 to the winding unit 42. The winding unit 42
supplied with the yarn supplying bobbin 11 winds the
yarn Y2 wound around the yarn supplying bobbin 11 to
form the package 15. When winding the yarn Y2 from the
yarn supplying bobbin 11, the winding unit 42
discharges the used yarn supplying bobbin 11 as the
empty bobbin 13. The empty bobbin 13 discharged from
the winding unit 42 is discharged from the machine of
33
the front automatic winder 4A by the fourth conveyance
unit 64, and is conveyed to the fifth conveyance unit
65. The fifth conveyance unit 65 carries out the empty
bobbin 13 conveyed from the fourth conveyance unit 64,
to the first conveyance unit 61 that supplies the empty
bobbin 13 to the spinning units 32 arranged on the
machine front side of the spinning machine 3.
[0059] A conveyance operation of the yarn
supplying bobbin 11 formed in each of the spinning
units 32 arranged on the machine rear side of the
spinning machine 3 is in common except that the yarn
supplying bobbin 11 is conveyed to the rear automatic
winder 4B, and the used yarn supplying bobbin 11 (empty
bobbin 13) is conveyed to each of the spinning units 32
arranged on the machine rear side. Therefore, detailed
description here is omitted.
[0060] An operation and effect of the yarn winding
system 1 of the above-described embodiment will be
described. In the present embodiment, one automatic
winder 4 is configured by one winding machine control
device 41 and the plurality of winding units 42 under
control of the one winding machine control device 41.
Further, in the yarn winding system 1 of the present
embodiment, two automatic winders 4 described above are
34
provided for one spinning machine 3. Furthermore, in
the yarn winding system 1 of the present embodiment,
the two automatic winders 4 and 4 are arranged on a
side of a right end part of the spinning unit 32 in the
arrangement direction D1, in the installation direction
D2 orthogonal to the arrangement direction D1. This
enables two automatic winders 4 and 4 to be arranged
for one spinning machine 3 without complicating a
configuration of the conveying device 5. Further, this
configuration makes it possible to arrange the two
automatic winders 4 and 4 while suppressing an
expansion of a space in the left-right direction
(arrangement direction D1).
[0061] Further, in the yarn winding system 1 of
the above-described embodiment, since two automatic
winders 4 and 4 are provided for one spinning machine 3,
it is possible to improve a manufacturing capability of
the package 15 without greatly changing a configuration
of conventional automatic winders 4 and 4, such as
increasing an output of a blower. Then, in the yarn
winding system 1 of the above-described embodiment
having this configuration, the yarn supplying bobbin 11
is conveyed from one spinning machine 3 to each of the
two automatic winders 4 and 4 without passing through
35
another automatic winder 4. Therefore, there is no
such a problem that the yarn supplying bobbin 11 is not
supplied to the winding unit 42 arranged at a position
far from a machine inlet of the automatic winder 4. As
described above, in the yarn winding system 1 of the
above-described embodiment, it is possible to improve a
manufacturing capability of the package 15, and reduce
a possibility that an operation of the yarn winding
system 1 is completely stopped.
[0062] In the yarn winding system 1 of the abovedescribed embodiment, the yarn supplying bobbin 11 is
conveyed from the spinning unit 32 arranged on the
machine front side of the spinning machine 3 to the
front automatic winder 4A, the empty bobbin 13 is
conveyed from the front automatic winder 4A to the
spinning unit 32 arranged on the machine front side of
the spinning machine 3, the yarn supplying bobbin 11 is
conveyed from the spinning unit 32 arranged on the
machine rear side of the spinning machine 3 to the rear
automatic winder 4B, and the empty bobbin 13 is
conveyed from the rear automatic winder 4B to the
spinning unit 32 arranged on the machine rear side of
the spinning machine 3.
[0063] This configuration makes it possible to
36
improve a manufacturing capability of the package 15
without greatly changing a configuration of the
conveying device 5 in the conventional spinning machine
3, and to reduce a possibility that an operation of the
yarn winding system 1 is completely stopped. Further,
in this configuration, the yarn supplying bobbin 11
formed by the spinning units 32 arranged on the machine
front side of the spinning machine 3 is returned as it
is as the empty bobbin 13 to the spinning unit 32
arranged on the machine front side of the spinning
machine 3. Therefore, it is easy to balance between
supply of the yarn supplying bobbin 11 and supply of
the empty bobbin 13. Similarly, in this configuration,
the yarn supplying bobbin 11 formed by the spinning
units 32 arranged on the machine rear side of the
spinning machine 3 is returned as it is as the empty
bobbin 13 to the spinning unit 32 arranged on the
machine rear side of the spinning machine 3. Therefore,
it is easy to balance between supply of the yarn
supplying bobbin 11 and supply of the empty bobbin 13.
For this reason, conveyance control in the conveying
device 5 can be simplified.
[0064] In the yarn winding system 1 of the abovedescribed embodiment, the winding machine control
37
device 41 provided to each of the two automatic winders
4 and 4 is arranged at an end part opposite to a side
where one spinning machine 3 is arranged, and the
display unit 41a and the operation unit 41b provided to
the winding machine control device 41 are provided such
that a display operation surface is orthogonal to the
arrangement direction. This configuration makes it
possible to bring the display units 41a (operation
units 41b) provided in each of the winding machine
control devices 41 closer to each other. This allows a
worker to operate and monitor the two automatic winders
4 and 4 without a large movement.
[0065] In the yarn winding system 1 of the abovedescribed embodiment, the two automatic winders 4 and 4
are arranged adjacent to each other, and the two
automatic winders 4 and 4 are arranged such that back
surfaces are facing each other. This configuration
enables arrangement of the yarn winding system 1
including one spinning machine 3 and two automatic
winders 4 and 4 in a small space.
[0066] An embodiment of the present invention has
been described above, but one aspect of the present
invention is not limited to the above-described
embodiment.
38
[0067]
In a yarn winding system 1A according to a first
alternative embodiment, a way of division of groups in
a plurality of spinning units 32 provided in a spinning
machine 3, a configuration of a part of a conveying
device 5 arranged on a lower side of the spinning
machine 3, and a configuration of a part, in the
conveying device 5, that connects the spinning machine
3 and each of two automatic winders 4 and 4 are
different from those in the yarn winding system 1 of
the above-described embodiment. Hereinafter, in the
yarn winding system 1A according to the first
alternative embodiment, a part different from the yarn
winding system 1 of the above-described embodiment will
be described.
[0068] Note that, as illustrated in FIG. 6, also
in the yarn winding system 1A according to the first
alternative embodiment, the automatic winder 4 arranged
on a front side in a front-rear direction in an
installation direction D2 may be referred to as “front
automatic winder 4A”, and the automatic winder 4
arranged on a rear side in the front-rear direction in
the installation direction D2 may be referred to as
“rear automatic winder 4B”.
39
[0069] In the yarn winding system 1A according to
the first alternative embodiment, a configuration in
which the plurality of spinning units 32 belong to any
one of two mutually different groups as in the abovedescribed embodiment is not essential. For this reason,
in the yarn winding system 1A, instead of the first
conveyance unit 61 of the above-described embodiment,
there is arranged one first conveyance unit 61A along a
lower side of all spinning units 32 arranged on a
machine rear side and a machine front side of the
spinning machine 3.
[0070] The first conveyance unit 61A is formed in
a U-shape with a machine outlet and a machine inlet
arranged on a machine right side of the spinning
machine 3 as both end parts of the conveyance unit. As
described above, the first conveyance unit 61A can be
appropriately configured with a known configuration
including: a guide groove formed by a guide plate; a
conveyor belt or a round belt provided on a lower side
of the guide groove along the guide groove; a driving
device that drives the conveyor belt or round belt; and
the like. The first conveyance unit 61A carries out a
yarn supplying bobbin 11 supplied to the first
conveyance unit 61A in simultaneous doffing of the
40
spinning unit 32 arranged in the spinning machine 3,
toward the rear automatic winder 4B and the front
automatic winder 4A. Further, the first conveyance
unit 61A carries in an empty bobbin 13 supplied from
the rear automatic winder 4B and the front automatic
winder 4A, to a lower side of the spinning units 32.
[0071] The conveying device 5 of the yarn winding
system 1A according to the first alternative embodiment
includes a branch part 68 that branches a conveyance
path and a merging part 69 that merges conveyance paths,
in order to correspond to a configuration in which the
yarn supplying bobbin 11 carried out from one first
conveyance unit 61A is supplied to two automatic
winders 4 (4A, 4B).
[0072] The branch part 68 is provided in a second
conveyance unit 62. The branch part 68 is a part that
distributes the yarn supplying bobbin 11 to the rear
automatic winder 4B and the front automatic winder 4A,
and is controlled by a winding machine control device
41. Configurations of a third conveyance unit 63 and a
fourth conveyance unit 64 are the same as those
described in the above-described embodiment, and
therefore a description thereof will be omitted. The
merging part 69 is provided in a fifth conveyance unit
41
65. The merging part 69 is a part that merges the
empty bobbins 13 conveyed from the rear automatic
winder 4B and the front automatic winder 4A. A
configuration of the fifth conveyance unit 65 is the
same as that described in the above-described
embodiment, and therefore a description thereof will be
omitted.
[0073] Note that a part where the second
conveyance unit 62 and the fifth conveyance unit 65
intersect in plan view illustrated in FIG. 6 is a
three-dimensional intersection such as, for example,
the fifth conveyance unit 65 intersects the second
conveyance unit 62 on an upper side in a vertical
direction.
[0074] In this way, the conveying device 5 is
connected from the one spinning machine 3 to each of
the rear automatic winder 4B and the front automatic
winder 4A via the branch part 68, and connected from
each of the rear automatic winder 4B and the front
automatic winder 4A to one spinning machine 3 via the
merging part 69.
[0075] In the yarn winding system 1A according to
the first alternative embodiment described above, the
two automatic winders 4 and 4 are arranged on a side of
42
a right end part of the spinning unit 32 in the
arrangement direction, in the installation direction D2
orthogonal to the arrangement direction D1. This
enables two automatic winders 4 and 4 to be arranged
for one spinning machine 3 without complicating a
configuration of the conveying device 5. Further, this
configuration makes it possible to arrange the two
automatic winders 4 and 4 while suppressing an
expansion of a space in the left-right direction
(arrangement direction D1).
[0076] Further, in the yarn winding system 1A
according to the first alternative embodiment described
above, since two automatic winders 4 and 4 are provided
for one spinning machine 3, it is possible to improve a
manufacturing capability of a package 15 without
greatly changing a configuration of the conventional
automatic winders 4 and 4, such as increasing an output
of a blower. Further, in the yarn winding system 1A
having this configuration, the yarn supplying bobbin 11
is conveyed from one spinning machine 3 to each of the
two automatic winders 4 and 4 without passing through
another automatic winder 4. Therefore, there is no
such a problem that the yarn supplying bobbin 11 is not
supplied to the winding unit 42 arranged at a position
43
far from a machine inlet of the automatic winder 4.
Further, even in a state where one of the two automatic
winders 4 and 4 is required to be stopped for
maintenance or the like, an operation of the yarn
winding system 1A can be continued by another automatic
winder 4 and one spinning machine 3. As described
above, in the yarn winding system 1A according to the
first alternative embodiment, it is possible to improve
a manufacturing capability of the package 15, and
reduce a possibility that an operation of the yarn
winding system 1A is completely stopped.
[0077]
A yarn winding system 1B according to a second
alternative embodiment includes, as illustrated in FIG.
7, a storage unit (first storage unit) 62A for a yarn
supplying bobbin 11 in a second conveyance unit 62, and
a storage unit (second storage unit) 65A for an empty
bobbin 13 in a fifth conveyance unit 65, in addition to
the configuration of the yarn winding system 1A
according to the first alternative embodiment.
Hereinafter, the storage unit 62A and the storage unit
65A will be described in detail.
[0078] The storage unit 62A is provided between a
branch part 68 and a machine inlet of a rear automatic
44
winder 4B, and between the branch part 68 and the
machine inlet of a front automatic winder 4A. The
storage unit 62A temporarily stores the yarn supplying
bobbin 11 conveyed from a spinning machine 3, and
adjusts a supply timing of the yarn supplying bobbin 11
to the rear automatic winder 4B and the front automatic
winder 4A. A stopper (not illustrated) or the like is
provided at a most downstream part of the storage unit
62A, and supply of the yarn supplying bobbin 11 to the
rear automatic winder 4B and the front automatic winder
4A is controlled by a winding machine control device 41.
[0079] The storage unit 65A is provided between a
machine outlet of the rear automatic winder 4B and a
merging part 69, and between a machine outlet of the
front automatic winder 4A and the merging part 69. The
storage unit 65A temporarily stores an empty bobbin 13
conveyed from the rear automatic winder 4B and the
front automatic winder 4A, and adjusts a supply timing
of the empty bobbin 13 to the spinning machine 3. A
stopper (not illustrated) or the like is provided at a
most downstream part of the storage unit 65A, and
supply of the empty bobbin 13 to the spinning machine 3
is controlled by the winding machine control device 41.
[0080] The yarn winding system 1B according to the
45
second alternative embodiment described above has the
following effects in addition to the effects of the
yarn winding system 1A according to the first
alternative embodiment described above. That is, since
the yarn winding system 1B according to the second
alternative embodiment described above includes the
storage unit 62A and the storage unit 65A, it is
possible to adjust a supply timing of the yarn
supplying bobbin 11 from the spinning machine 3 to the
rear automatic winder 4B and the front automatic winder
4A, and a supply timing of the empty bobbin 13 from the
rear automatic winder 4B and the front automatic winder
4A to the spinning machine 3. This enables an
operation of the spinning machine 3 to be continued
even when the supply of the yarn supplying bobbin 11
from the spinning machine 3 to the rear automatic
winder 4B and the front automatic winder 4A becomes
excessive. Further, even when the supply of the yarn
supplying bobbin 11 from the rear automatic winder 4B
and the front automatic winder 4A to the spinning
machine 3 becomes excessive, an operation of the rear
automatic winder 4B and the front automatic winder 4A
can be continued.
[0081]
46
A yarn winding system 1C according to a third
alternative embodiment includes, as illustrated in FIG.
8, a mixed conveyance unit 67 that conveys a yarn
supplying bobbin 11 and an empty bobbin 13 in a mixed
state, instead of the second conveyance unit 62 and the
fifth conveyance unit 65 of the configuration of the
yarn winding system 1A according to the first
alternative embodiment. Hereinafter, the mixed
conveyance unit 67 will be described in detail.
[0082] The mixed conveyance unit 67 is arranged
between one spinning machine 3 and a plurality of
automatic winders 4 and 4. More specifically, the
mixed conveyance unit 67 includes: a first merging part
67A connected to a machine outlet where the yarn
supplying bobbin 11 is carried out from one spinning
machine 3; a first branch part 67B connected to a
machine inlet where the empty bobbin 13 is carried into
one spinning machine 3; second branch parts (branch
parts) 67C and 67C connected to machine inlets where
the yarn supplying bobbins 11 are individually carried
into the rear automatic winder 4B and the front
automatic winder 4A; and second merging parts (merging
parts) 67D and 67D connected to machine outlets where
empty bobbins 13 are carried out individually from the
47
rear automatic winder 4B and the front automatic winder
4A.
[0083] As in each of the conveyance units 61 to 65
described above, the mixed conveyance unit 67 can be
appropriately configured with a known configuration
including: a guide groove formed by a guide plate; a
conveyor belt or a round belt provided on a lower side
of the guide groove along the guide groove; a driving
device that drives the conveyor belt or round belt; and
the like.
[0084] The first branch part 67B and the second
branch parts 67C and 67C are provided with an
identification unit that identifies the yarn supplying
bobbin 11 and the empty bobbin 13. Examples of the
identification unit include a photoelectric sensor that
detects an amount of yarn wound around the bobbin B,
and a contact unit that is provided so as to be
swingable and able to contact the bobbin B traveling on
the conveyance unit, and identifies the yarn supplying
bobbin 11 and the empty bobbin 13 on the basis of an
amount of rotation of the member when the bobbin B has
passed.
[0085] Providing such an identification unit in
the first branch part 67B enables the yarn supplying
48
bobbin 11 to be exclusively selected from the mixed
conveyance unit 67 in which the yarn supplying bobbin
11 and the empty bobbin 13 are conveyed in a mixed
state, to be supplied to the spinning machine 3.
Similarly, providing such an identification unit in the
second branch parts 67C and 67C enables the empty
bobbin 13 to be exclusively selected from the mixed
conveyance unit 67 in which the yarn supplying bobbin
11 and the empty bobbin 13 are conveyed in a mixed
state, to be supplied to the rear automatic winder 4B
and the front automatic winder 4A.
[0086] In the yarn winding system 1C having the
configuration of the conveying device 5 as described
above, the yarn supplying bobbin 11 discharged from one
spinning machine 3 is conveyed to each of the rear
automatic winder 4B and the front automatic winder 4A
via the mixed conveyance unit 67.
[0087] The yarn winding system 1B according to the
third alternative embodiment described above also has
effects similar to those of the yarn winding systems 1
and 1A according to the above-described embodiment and
the first alternative embodiment.
[0088]
A yarn winding system 1D according to a fourth
49
alternative embodiment has a configuration in which, as
illustrated in FIG. 9, in the configuration of the yarn
winding system 1A according to the first alternative
embodiment, two automatic winders 4 and 4 arranged at a
right end part of a spinning machine 3 in an
arrangement direction D1 are also arranged at a left
end part of the spinning machine 3 in the arrangement
direction D1. In such a configuration, a configuration
of a conveying device 5 arranged on a machine of the
spinning machine 3 is different from that of the yarn
winding system 1A according to the first alternative
embodiment. That is, the yarn winding system 1D
according to the fourth alternative embodiment includes
a first conveyance unit 61C and a first conveyance unit
61D, instead of the first conveyance unit 61A of the
yarn winding system 1A according to the first
alternative embodiment. Hereinafter, the first
conveyance unit 61C and the first conveyance unit 61D
will be described in detail.
[0089] In the spinning machine 3 according to the
fourth alternative embodiment, a plurality of spinning
units 32 belong to any one of two mutually different
groups. Specifically, the spinning machine 3 has the
spinning unit 32 (a spinning unit belonging to a first
50
group) arranged on a machine front side, and the
spinning unit 32 (a spinning unit belonging to a second
group) arranged on a machine rear side. Each of the
above two groups is also a group of the spinning unit
32 in which simultaneous doffing is performed.
[0090] The first conveyance unit 61C is provided
on a lower side of the spinning units 32 arranged on
the machine rear side of the spinning machine 3, along
the arrangement direction D1 of the spinning units 32.
The first conveyance unit 61C carries out a yarn
supplying bobbin 11 supplied to the first conveyance
unit 61 in simultaneous doffing of the spinning unit 32
arranged on the machine rear side of the spinning
machine 3 toward two automatic winders 4 and 4 arranged
on a side on the right of the spinning machine 3 in the
arrangement direction D1, and carries in an empty
bobbins 13 supplied from the two automatic winders 4
and 4 arranged on a side on the left of the spinning
machine 3 in the arrangement direction D1, to a lower
side of the spinning units 32.
[0091] The first conveyance unit 61D is provided
on a lower side of the spinning units 32 arranged on
the machine front side of the spinning machine 3, along
