Patent document 1: japanese patent laid-open publication No. 2011-47074

The hoppers provided in the plurality of winding units need to be appropriately replenished with empty paper tubes. Conventionally, replenishment of empty paper tubes into respective hoppers is performed by manual work by an operator. However, the task of moving the operator to each stocker to replenish the empty paper tubes is very troublesome for the operator and takes a long time.

Disclosure of Invention

The invention provides a paper tube replenishing device for efficiently replenishing empty paper tubes to respective hoppers of a plurality of winding units provided in a false twisting machine.

In a false twist processing machine provided with a plurality of paper tube replenishment units in a predetermined arrangement direction, the paper tube replenishment device of the present invention is a false twist processing machine provided with a multi-layer winding unit for replenishing empty paper tubes to a plurality of hoppers, the winding unit having a winding device and the hoppers capable of storing the empty paper tubes replenished to the winding device, characterized by comprising a paper tube moving path provided with a plurality of layers corresponding to the multi-layer winding unit and extending in the arrangement direction so that the empty paper tubes replenished to the plurality of hoppers can move in the arrangement direction, the paper tube moving path comprising: a support surface extending along the arrangement direction and supporting the blank tube from below; a replenishment port provided at an end of the paper tube moving path in the arrangement direction, for replenishing the empty paper tube; and a plurality of guide portions for guiding the blank tubes moving in the arrangement direction to the plurality of hoppers, respectively.

According to the present invention, the empty paper tubes fed from the feeding port to the paper tube moving path are moved in the arrangement direction in the paper tube moving path. Then, the blank tubes moving in the arrangement direction are conveyed to the hoppers via the plurality of guide portions. Therefore, the empty paper tubes are replenished without the operator moving to each stocker. This makes it possible to efficiently replenish the blank tube to each stocker provided in the plurality of winding units of the false twist machine.

The paper tube replenishment device according to the present invention preferably further includes a plurality of 1 st stoppers provided at positions corresponding to the respective guide portions of the paper tube moving path, and the 1 st stoppers are capable of switching between an allowable state in which the empty paper tube is allowed to move from the paper tube moving path to the hopper via the guide portions and a restricting state in which the empty paper tube is restricted from moving from the paper tube moving path to the hopper via the guide portions.

In the present invention, the 1 st stopper portion corresponding to the guide portion for guiding the empty paper tube to the hopper that is the replenishment target of the empty paper tube can be set to the permitted state, and the 1 st stopper portion corresponding to the guide portion for guiding the empty paper tube to the hopper that is not the replenishment target of the empty paper tube can be set to the restricted state. Thus, the empty paper tubes can be selectively replenished to the hopper which is intended to replenish the empty paper tubes among the plurality of hoppers.

The paper tube replenishment device according to the present invention preferably further includes a plurality of 2 nd stoppers provided at positions corresponding to the respective guide portions in the paper tube moving path, wherein the 2 nd stoppers are capable of switching between an allowable state in which the empty paper tubes are allowed to move in the arrangement direction in the paper tube moving path and a guide state in which the empty paper tubes are guided to the hopper via the guide portions, and when the 2 nd stoppers are in the guide state, the empty paper tubes are restricted from moving beyond the 2 nd stoppers in the arrangement direction.

According to the present invention, the 2 nd stopper portion corresponding to the guide portion for guiding the blank tube to the hopper to be replenished with the blank tube is set in the guide state, whereby the blank tube can be restricted from moving beyond the 2 nd stopper portion in the arrangement direction. Therefore, the empty paper tube can be prevented from moving to a position corresponding to the stocker which is not the replenishment object in the paper tube moving path. Further, the empty paper tube can be properly guided to the hopper to be replenished by the 2 nd stopper portion in the guide state. This makes it possible to appropriately replenish the empty paper tube to the target stacker.

The paper tube replenishment device of the present invention preferably further includes a plurality of spacers for making the interval in the arrangement direction of the empty paper tubes adjacent to each other in the paper tube moving path equal to the interval in the arrangement direction of the adjacent guide portions.

For example, in the case of a structure in which one end portion of the paper tube moving path in the arrangement direction is closed, empty paper tubes, which are not replenished to the stocker, among the plurality of empty paper tubes moving in the paper tube moving path are conveyed to one end portion of the paper tube moving path and remain in the paper tube moving path. Then, when the empty paper tubes are replenished to any one of the hoppers in a state where the plurality of empty paper tubes stay in the paper tube moving path, any one of the empty paper tubes staying in the paper tube moving path is replenished to the hopper. Here, when a plurality of blank tubes move simultaneously in the paper tube moving path, the interval between adjacent blank tubes in the arrangement direction may be narrowed. Then, the empty paper tube that stays in the paper tube moving path may be located at a position where the empty paper tube cannot be properly guided to the hopper via the guide portion. According to the present invention, the interval between adjacent blank tubes can be made the same as the interval between adjacent guide portions by the spacers. Thus, each empty tube that stays in the tube moving path can be prevented from being present at a position where it cannot be properly guided to the hopper via the guide portion, and the empty tube can be more reliably replenished to the hopper.

The paper tube replenishment device of the present invention preferably further includes a belt to which the plurality of spacers are attached, and the belt is movable in the arrangement direction and is circulated in the paper tube moving path.

In the case where only the spacer is provided, the spacer remains in the paper tube moving path after the empty paper tube moving in the paper tube moving path is replenished to the stocker. The spacers remaining in the paper tube travel path need to be collected by the operator, which is troublesome for the operator. According to the present invention, the plurality of spacers are attached to the endless belt movable in the direction of arrangement in the paper tube moving path. Therefore, it is not necessary for the worker to collect the spacers remaining in the paper tube travel path, and the trouble of the worker can be reduced.

The paper tube replenishment device of the present invention preferably further comprises an empty paper tube automatic feeding device capable of automatically feeding an empty paper tube from the replenishment port to the paper tube moving path.

According to the present invention, the trouble of the operator can be reduced and the working time can be shortened, compared with the case where the operator puts the empty paper tube on the paper tube moving path by manual work.

In the paper tube replenishment device according to the present invention, the replenishment port is preferably provided only at one end portion of the paper tube moving path in the arrangement direction.

According to the present invention, since the empty paper tubes are only required to be replenished from the replenishment ports provided only at one end portion of the paper tube moving path, it is easy to replenish the empty paper tubes to the paper tube moving path, compared with the case where the empty paper tubes are replenished from the replenishment ports provided at both end portions of the paper tube moving path.

In the paper tube replenishment device according to the present invention, it is preferable that the empty paper tube in the paper tube moving path is pushed by the empty paper tube newly replenished from the replenishment port to the paper tube moving path and moved in the alignment direction.

According to the present invention, the empty paper tubes supplied to the paper tube moving path by the operator push the adjacent empty paper tubes, thereby moving the empty paper tubes in the arrangement direction. Therefore, the empty paper tubes can be moved in the arrangement direction without providing a device for moving the empty paper tubes of the paper tube moving path in the arrangement direction. Thus, the device as a whole does not need a complicated structure, and the cost of the device can be reduced.

In the paper tube replenishment device according to the present invention, the paper tube moving path preferably includes a conveying device that conveys the empty paper tubes in the arrangement direction.

According to the present invention, empty paper tubes of the paper tube moving path can be conveyed in the arrangement direction by the conveying device. Therefore, the worker is not required to press the blank tube by manual operation, and the trouble of the worker can be reduced.

In the paper tube replenishment device according to the present invention, it is preferable that the paper tube moving path has a wall portion connected to both end portions of the support surface in an orthogonal direction orthogonal to the arrangement direction, and the height of the wall portion is longer than the diameter of the empty paper tube.

According to the present invention, the empty paper tubes moving through the paper tube moving path can be prevented from falling off the paper tube moving path to the outside, and the empty paper tubes can be more reliably replenished to the respective hoppers.

In the paper tube replenishment device according to the present invention, it is preferable that the paper tube moving path has a ceiling portion extending in the arrangement direction and connecting the wall portions on both sides.

According to the present invention, the empty paper tube moving through the paper tube moving path can be more reliably prevented from falling out of the paper tube moving path.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(integral construction of false twisting machine 1)

Fig. 1 is a side view showing a schematic configuration of a false twist machine 1 according to the present embodiment. Fig. 2 is a view from the direction II in fig. 1. Hereinafter, the direction perpendicular to the paper surface in fig. 1 is referred to as the machine body longitudinal direction, and the left-right direction is referred to as the machine body width direction. The direction orthogonal to both the longitudinal direction and the width direction of the machine body is defined as the vertical direction (vertical direction) in which gravity acts. Hereinafter, the above directional terms will be appropriately used for explanation.

The false twisting machine 1 is configured to be capable of false twisting a yarn Y made of synthetic fibers such as nylon (polyamide fibers). The false twisting machine 1 includes a yarn feeding section 2 for feeding the yarn Y, a processing section 3 for false twisting the yarn Y fed from the yarn feeding section 2, a winding section 4 for winding the yarn Y processed by the processing section 3 around an empty bobbin (empty paper tube of the present invention) to form a winding bobbin Bw, and a control section 40 (see fig. 5). A plurality of components (described later) included in the yarn feeding section 2, the processing section 3, and the winding section 4 are arranged in the longitudinal direction of the machine body orthogonal to the running surface (paper surface of fig. 1) of the yarn on which the yarn path from the yarn feeding section 2 to the winding section 4 passes through the processing section 3 is arranged.

The yarn feeding section 2 has a creel 7 for holding a plurality of yarn feeding packages Ps, and supplies a plurality of yarns Y to the processing section 3. The processing unit 3 is configured such that a 1 st godet 11, a stop yarn guide 12, a 1 st heating device 13, a cooling device 14, a false twisting device 15, a 2 nd godet 16, a interlacing device 17, a 3 rd godet 18, a 2 nd heating device 19, and a 4 th godet 20 are arranged in this order from the upstream side in the yarn advancing direction. The winding unit 4 winds the yarn Y false twisted by the processing unit 3 around the winding bobbin Bw by the winding device 21 to form a winding package Pw.

The false twist machine 1 further includes a main body 8 and a winding table 9 arranged at intervals in the machine body width direction. The main body 8 and the winding stand 9 are provided so as to extend substantially the same length in the longitudinal direction of the main body, and are disposed so as to face each other. The upper part of the main body 8 and the upper part of the winding stand 9 are connected by a support frame 10. The respective devices constituting the processing section 3 are mainly mounted on the main body 8 and the support frame 10. A work space 22 for an operator to perform a work such as wire hanging on each device is formed by the main body 8, the winding stand 9, and the support frame 10. The yarn channel is formed so that the yarn Y mainly runs around the working space 22.

The false twist machine 1 has a unit cell called a span including 1 set of main bodies 8 arranged to face each other and a winding table 9. In one span, each device is configured to be capable of simultaneously performing false twisting processing on a plurality of threads Y traveling in a state of being aligned along the machine body length direction. As an example, a total of 12 winding devices 21 (see fig. 2) are provided in 3 layers and 4 rows on the winding table 9 included in one span. Furthermore, there is a supporting frame 10 between two adjacent spans. In the present embodiment, the interval between the two winding devices 21 adjacent in the longitudinal direction of the machine body in one span is the same as the interval between the two winding devices 21 adjacent in the longitudinal direction of the machine body across the support frame 10. The false twist machine 1 is configured such that the span is arranged symmetrically left and right on the paper surface with the center line C of the main machine body 8 in the machine body width direction as a symmetry axis (the main machine body 8 is shared by the left and right spans), and a plurality of spans are arranged in the machine body length direction.

(construction of processing section)

Next, each constituent element of the processing unit 3 will be described. The 1 st godet 11 is configured to convey the yarn Y fed from the yarn feeding section 2 to the 1 st heating device 13. The 1 st godet 11 is disposed above the winding stage 9 (see fig. 1). The 1 st godet 11 is arranged in 1 row in the longitudinal direction of the machine body.

The anti-twist yarn guide 12 prevents the twist applied to the yarn Y by the false twisting device 15 described later from being propagated to a position upstream of the anti-twist yarn guide 12 in the yarn advancing direction. The anti-twist yarn guide 12 is disposed at a position downstream of the 1 st yarn feeding roller 11 in the yarn traveling direction and upstream of the 1 st heating device 13 in the yarn traveling direction. The anti-twist yarn guides 12 are provided independently of each of the plurality of yarns Y fed from the yarn feeding section 2, and are arranged in 1 row in the longitudinal direction of the machine body, for example.

The 1 st heating device 13 is provided in the support frame 10 (see fig. 1) for heating the yarn Y fed from the 1 st godet 11. The 1 st heating device 13 is provided in plural with respect to the plural wires Y supplied from the wire supplying portion 2, and is arranged in 1 row in the machine body length direction.

The cooling device 14 is used for cooling the yarn Y heated by the 1 st heating device 13. The cooling device 14 is disposed at a position downstream of the 1 st heating device 13 in the yarn traveling direction and upstream of the false twisting device 15 in the yarn traveling direction. The cooling device 14 is provided in plural with respect to the plural wires Y supplied from the wire supplying portion 2, and is arranged in 1 row in the machine body longitudinal direction.

The false twisting device 15 is a device for twisting the yarn Y. The false twisting device 15 is arranged immediately downstream in the yarn traveling direction of the cooling device 14. The false twisting device 15 is arranged in plural in the longitudinal direction of the machine body. For example, each span is provided with 12 false twisting devices 15.

The 2 nd yarn feeding roller 16 is a roller for feeding the yarn Y twisted by the false twisting device 15 toward the interlacing device 17. The 2 nd godet 16 is disposed on the downstream side of the main body 8 in the yarn advancing direction of the false twisting device 15. The feeding speed of the yarn Y by the 2 nd yarn feeding roller 16 is faster than the feeding speed of the yarn Y by the 1 st yarn feeding roller 11. Thus, the yarn Y is stretched between the 1 st godet 11 and the 2 nd godet 16.

The interlacing device 17 is a device for applying interlacing by spraying air to the yarn Y. The winding device 17 is disposed below the 2 nd godet 16 in the main body 8.

The 3 rd godet 18 is a roller for conveying the yarn Y subjected to the interlacing by the interlacing device 17 toward the 2 nd heating device 19. The 3 rd godet 18 is disposed below the winding device 17 in the main body 8. The 3 rd godet 18 delivers the yarn Y at a slower rate than the 2 nd godet 16 delivers the yarn Y. Thus, the yarn Y is relaxed between the 2 nd and 3 rd godets 16 and 18.

The 2 nd heating device 19 is a device for heating the yarn Y fed from the 3 rd godet 18. The 2 nd heating device 19 is disposed below the 3 rd godet 18 in the main body 8. The 2 nd heating devices 19 extend in the up-down direction, one each being provided in one span.

The 4 th godet 20 is a roller for feeding the yarn Y heat-treated by the 2 nd heating device 19 toward the winding device 21. The 4 th godet 20 is disposed below the winding stage 9. The 4 th godet 20 delivers the yarn Y at a slower rate than the 3 rd godet 18 delivers the yarn Y. Thus, the yarn Y is relaxed between the 3 rd and 4 th godets 18 and 20.

In the processing unit 3 configured as described above, the yarn Y stretched between the 1 st yarn feeding roller 11 and the 2 nd yarn feeding roller 16 is twisted by the false twisting device 15. The twist formed by the false twisting device 15 propagates to the anti-twist yarn guide 12, but does not propagate upstream in the yarn advancing direction of the anti-twist yarn guide 12. The yarn Y twisted while being stretched is heated by the 1 st heating device 13 and heat-set, and then cooled by the cooling device 14. The yarn Y is untwisted downstream of the false twisting device 15, but the above-described heat setting maintains the state in which each filament is false twisted into a wavy form. The yarn Y false-twisted by the false twisting device 15 is wound by the winding device 17 while being loosened between the 2 nd yarn feeding roller 16 and the 3 rd yarn feeding roller 18, and is guided downstream in the yarn traveling direction. Further, the yarn Y is heat-set by the 2 nd heating device 19 while being relaxed between the 3 rd godet 18 and the 4 th godet 20. Finally, the yarn Y fed from the 4 th godet 20 is wound by the winding device 21 to form a winding package Pw.

(constitution of winding portion 4)

Next, the structure of the winding unit 4 will be described with reference to fig. 2 and 3. Fig. 3 is a schematic view showing the structure of the winding portion 4, and is a view of the winding portion 4 as seen from the longitudinal direction of the machine body. As shown in fig. 3, in the winding portion 4, a plurality of winding units 30 each having the winding device 21, the stocker 23, and the accumulating portion 24 are provided in the machine body longitudinal direction, that is, the arrangement direction, and a plurality of layers are provided. As shown in fig. 2, a total of 12 winding units 30 of 4 rows and 3 layers are provided in the vertical direction with respect to one winding table 9.

The winding device 21 is a device for winding the yarn Y around the winding bobbin Bw to form a winding package Pw. The winding device 21 has a single cradle 31 rotatably supporting the winding bobbin Bw. The winding bobbin Bw supported by the cradle 31 is rotationally driven by a motor, not shown, for example. The winding device 21 rotationally drives the winding bobbin Bw supported by the cradle 31, thereby winding the yarn Y around the winding bobbin Bw to form a winding package Pw. The cradle 31 is rotatable about a rotation shaft 31a extending in the longitudinal direction of the machine body.

Each stocker 23 can store empty bobbins Bw (empty paper tubes) supplied to the winding device 21. The empty bobbin Bw is an empty winding bobbin Bw in a state where the yarn Y is not wound. The stocker 23 has a bottom surface for supporting the empty bobbin Bw from below, and side walls provided on both sides in the longitudinal direction of the body of the empty bobbin Bw placed on the bottom surface. The bottom surface of the stocker 23 is inclined downward toward the side where the winding device 21 is disposed in the machine body width direction. The empty bobbin Bw stored in the stocker 23 moves along the bottom surface inclined downward toward the side where the winding device 21 is arranged in the body width direction. Further, a regulating member, not shown, is disposed at the front end of the stocker 23 on the side where the winding device 21 is disposed in the body width direction. The empty bobbin Bw moving along the bottom surface of the stocker 23 is contacted with a regulating member (not shown), thereby being regulated from falling from the front end of the stocker 23 to the winding device 21 side. In the present embodiment, at most 4 empty bobbins Bw can be stored in the stocker 23.

The empty bobbin Bw stored in the stocker 23 is supplied to the winding device 21, for example, as follows. First, the cradle 31 rotates about the rotation shaft 31a, and thereby the portion of the cradle 31 capable of supporting the winding bobbin Bw moves to the vicinity of the front end of the stocker 23 on the side where the winding device 21 is disposed in the body width direction. Then, the restriction by the restricting member provided in the stocker 23 is released, and the empty bobbin Bw stored in the stocker 23 is supported by the cradle 31. Then, the cradle 31 is rotated about the rotation shaft 31a, returns to the winding position where the winding device 21 winds the yarn Y, and is again regulated by the regulating member of the stocker 23. In this way, the empty bobbin Bw stored in the stocker 23 is supplied to the winding device 21.

The cradle 31 may be fixed so as not to rotate. In this case, the stocker 23 can rotate around a rotation axis extending in the longitudinal direction of the main body. Then, the empty bobbin Bw stored in the stocker 23 is supplied to the winding device 21 by the stocker 23 rotating with respect to the fixed cradle 31.

The storage unit 24 stores the full-wound winding package Pw formed by the winding device 21. When the winding package Pw becomes full, the cradle 31 rotates about the rotation axis in the longitudinal direction of the machine body, and the winding bobbin Bw supported by the cradle 31 is detached from the winding device 21 and supplied to the accumulating portion 24. For example, the storage unit 24 can store at most 3 winding packages Pw. In addition, when a break occurs during winding of the yarn Y by the winding device 21, the winding package Pw may be supplied to the storage unit 24 even if it is not fully wound.

(electric constitution)

Fig. 5 is a block diagram showing an electrical configuration of the false twist texturing machine 1. The control unit 40 controls the operations of the respective constituent elements of the wire feeding unit 2, the processing unit 3, and the winding unit 4. In fig. 5, the control unit 40 is connected to one 1 st stopper 52 and one 2 nd stopper 53 of a plurality of 1 st stoppers 52 (described later) and a plurality of 2 nd stoppers 53 (described later) for the reason of the paper surface, but is actually connected to the other 1 st stoppers 52 and 2 nd stoppers 53.

(constitution of paper tube replenishing device 50)

Next, the structure of the paper tube replenishment device 50 will be described with reference to fig. 2 to 4. Fig. 4 is a sectional view IV-IV of fig. 2, and is a diagram showing a structure of the winding portion 4 provided with the paper tube replenishment device 50 when viewed from the up-down direction. In fig. 4, for the sake of explanation, the paper tube replenishment device 50 is described as being provided for one winding table 9, but in actuality, one paper tube replenishment device 50 is provided across a plurality of winding tables 9.

The paper tube replenishment device 50 is a device for replenishing the empty tubes Bw for each of the plurality of hoppers 23. As shown in fig. 4, the paper tube replenishment device 50 includes a paper tube moving path 51, a plurality of 1 st stoppers 52, a plurality of 2 nd stoppers 53, a plurality of spacers 54, and a belt 55.

As shown in fig. 3, the paper tube moving path 51 is provided with a plurality of layers corresponding to the multi-layer winding unit 30. That is, in the present embodiment, the paper tube moving path 51 is provided with 3 layers in the up-down direction. The paper tube moving path 51 is a cylindrical shape extending along the longitudinal direction (alignment direction) of the machine body. The plurality of empty tubes Bw are movable in the longitudinal direction of the machine body inside the cylindrical paper tube moving path 51. The inner surface of the lower side of the cylindrical paper tube moving path 51 is a supporting surface 51a for supporting the empty bobbin Bw from below. As shown in fig. 2, the paper tube moving path 51 is configured to include all the hoppers 23 along the longitudinal direction of the machine body when viewed from the machine body width direction. The end of the paper tube moving path 51 opposite to the side where the replenishment port 61 (described later) is provided is closed in the longitudinal direction of the machine body. In the present embodiment, the cylindrical portion of the paper tube moving path 51 includes the wall portion and the ceiling portion of the present invention.

Each paper tube moving path 51 has a replenishment port 61 and a plurality of guide portions 62. The replenishment port 61 is for replenishing the empty bobbin Bw into the paper tube moving path 51. The replenishment port 61 is provided only at one end portion of the paper tube moving path 51 in the longitudinal direction of the machine body. In the present embodiment, the replenishment port 61 is provided at an end portion above the paper surface in fig. 4 among the end portions of the paper tube moving path 51.

The guide portion 62 guides the empty bobbin Bw moving in the longitudinal direction of the machine body inside the paper tube moving path 51 to each stocker 23. In the present embodiment, the guide portion 62 is a plurality of opening portions formed at positions corresponding to the hoppers 23 on the side surface of the paper tube moving path 51. Each guide portion 62 overlaps each stocker 23 in the machine body longitudinal direction when viewed from the machine body width direction. The paper tube moving path 51 is connected to each hopper 23 at a position where each guide 62 is formed. As shown in fig. 3, the guide 62 opens toward the side of the body in the width direction where the stocker 23 is disposed. The guide 62 is opened so as to incline downward from the paper tube moving path 51 toward the hopper 23. The empty bobbin Bw in the paper tube moving path 51 at a position corresponding to the guide part 62 moves toward the hopper 23 by the guide part 62 which is opened obliquely downward without accompanying an external force in the machine body width direction.

As shown in fig. 4, the 1 st stopper portions 52 are plate-like members provided at positions corresponding to the guide portions 62 on the side surfaces of the paper tube moving path 51 and extending in the longitudinal direction of the machine body. The 1 st stopper 52 is switchable between a permission state (a portion shown by a broken line in fig. 4) in which the empty bobbin Bw is permitted to move from the paper tube moving path 51 toward the hopper 23 via the guide 62, and a restriction state (a portion shown by a solid line and a diagonal line in fig. 4) in which the empty bobbin Bw is restricted from moving from the paper tube moving path 51 toward the hopper 23 via the guide 62. The 1 st stopper 52 is driven by a motor, not shown, and can be switched between an allowable state and a restricting state. The driving of the 1 st stopper 52 is controlled by the control section 40. The drive source of the 1 st stopper 52 is not limited to the motor. For example, the 1 st stopper 52 may be driven by air (air pressure).

The 1 st stopper 52 in the permitted state opens the guide 62 formed on the side surface of the paper tube moving path 51. When the 1 st stopper 52 is in the permitted state, the empty bobbin Bw located at the position corresponding to the guide 62 of the paper tube moving path 51 moves toward the stocker 23 via the guide 62 which is opened obliquely downward. The 1 st stopper 52 in the restricted state closes a part or all of the guide 62 formed on the side surface of the paper tube moving path 51. When the 1 st stopper 52 is in the restricted state, the empty bobbin Bw of the paper tube moving path 51 is restricted from moving toward the stocker 23 by the guide 62. The 1 st stopper 52 is movable in the up-down direction to switch between the allowable state and the restricting state, and the 1 st stopper 52 in the allowable state is located above the 1 st stopper 52 in the restricting state. The 1 st stopper 52 in the permitted state may be located below the 1 st stopper 52 in the restricted state. The 1 st stopper 52 can be switched between the permission state and the restriction state by moving along the longitudinal direction of the machine body. The 1 st stopper 52 may be a door that can be switched between the permission state and the restriction state by rotating about any one of the longitudinal direction, the width direction, and the vertical direction of the machine body.

As shown in fig. 4, the 2 nd stopper portions 53 are provided at positions corresponding to the guide portions 62 of the paper tube moving path 51. The 2 nd stopper 53 is a disk-shaped member having substantially the same shape as the cross-sectional shape of the paper tube moving path 51. The 2 nd stopper 53 extends in the machine body width direction from the position of the opening end of the guide 62, which is the opening end on the opposite side of the replenishment port 61 in the machine body longitudinal direction, so as to penetrate the inside of the paper tube moving path 51 when viewed in the vertical direction.

The 2 nd stopper 53 is switchable between an allowable state (a portion indicated by a broken line in fig. 4) in which the empty bobbin Bw is allowed to move along the longitudinal direction of the machine body inside the paper tube moving path 51, and a guide state (a portion indicated by a solid line and a diagonal line in fig. 4) in which the empty bobbin Bw is guided to the stocker 23 via the guide portion 62. When the 2 nd stopper 53 is in the guide state, the empty bobbin Bw is restricted from moving beyond the 2 nd stopper 53 in the longitudinal direction of the machine body. The 2 nd stopper 53 is driven by a motor, not shown, and can be switched between the permission state and the guiding state. The driving of the 2 nd stopper 53 is controlled by the control section 40. The drive source of the 2 nd stopper 53 is not limited to the motor. For example, the 2 nd stopper 53 may be driven by air (air pressure).

The 2 nd stopper 53 is movable between the inside of the paper tube moving path 51 and the outside of the paper tube moving path 51 via a slit, not shown, formed in the paper tube moving path 51. The 2 nd stopper 53 in the permitted state is located outside the paper tube moving path 51, and opens the inside of the paper tube moving path 51 along the longitudinal direction of the machine body. The 2 nd stopper 53 in the guide state is located inside the paper tube moving path 51, closes the inside of the paper tube moving path 51 along the longitudinal direction of the machine body, and forms a path for guiding the empty bobbin Bw to the stocker 23 via the guide 62. In this way, the 2 nd stopper 53 can be switched between the permitted state and the guide state by moving in the up-down direction, and the 2 nd stopper 53 in the permitted state is located above the 2 nd stopper 53 in the guide state. The 2 nd stopper 53 in the permitted state may be located below the 2 nd stopper 53 in the guided state. The 2 nd stopper 53 can be switched between the allowing state and the guiding state by moving in the body width direction.

The spacer 54 is a member for making the interval in the longitudinal direction of the body of the empty bobbin Bw adjacent to the paper tube moving path 51 the same as the interval in the longitudinal direction of the body of the adjacent guide part 62. In the present embodiment, the plurality of spacers 54 and the 2 nd stopper 53 in the guide state are configured so as not to interfere with each other. For example, a cutout is formed below the 2 nd stopper 53. The spacers 54 are arranged so as to be positioned at the cut-out portions of the 2 nd stopper 53 in the guide state. Here, "the interval in the machine body longitudinal direction of the adjacent empty bobbin Bw is made the same as the interval in the machine body longitudinal direction of the adjacent guide portion 62" means that the interval between the center of gravity position of one empty bobbin Bw in the machine body longitudinal direction and the center of gravity position of the adjacent empty bobbin Bw is made the same as the interval between the center of gravity position of one guide portion 62 in the machine body longitudinal direction and the center of gravity position of the adjacent guide portion 62.

The plurality of spacers 54 are attached to the belt 55 at equal intervals, and the belt 55 is movable in the longitudinal direction of the machine body on the paper tube moving path 51 and is circulated. The belt 55 is an endless belt, and as shown in fig. 4, travels along the longitudinal direction of the machine body on the inner and outer sides of the paper tube moving path 51 in the machine body width direction. In this embodiment, the belt 55 has no power. The plurality of spacers 54 are movable along the longitudinal direction of the machine body integrally with the belt 55. The belt 55 and the 2 nd stopper 53 in the guide state are configured so as not to interfere with each other. For example, the belt 55 is configured to be positioned at a notched portion of the 2 nd stopper 53 in the guide state. The belt 55 may travel along the longitudinal direction of the machine body on the inner and outer sides of the paper tube moving path 51 in the up-down direction.

A series of operations for replenishing the empty bobbin Bw to the stocker 23 by the paper tube replenishment device 50 in the present embodiment will be described below. First, which stocker 23 to be replenished with the empty bobbin Bw is determined by the operator's visual observation. For example, as shown in fig. 4, when there are two empty bobbins Bw stored in the 3 rd stocker 23 (hereinafter, abbreviated as 3 rd stocker 23) from the side of the plurality of stockers 23 where the replenishment port 61 is provided in the machine body longitudinal direction, the stocker 23 is the replenishment target of the empty bobbins Bw. When the number of empty tubes Bw stored in the stocker 23 is several, the stocker 23 can be freely determined by the operator as a supplement target of the empty tubes Bw. The operator inputs information of the stocker 23 to be replenished with the empty bobbin Bw to a work terminal (not shown). Information input to the work terminal is sent to the control unit 40.

Next, based on the signal, the control unit 40 controls the state switching of the 1 st stopper 52 and the 2 nd stopper 53. For example, when the 3 rd stocker 23 is a replenishment target of the empty bobbin Bw, the control unit 40 controls switching so that the 1 st stopper 52 corresponding to the 3 rd stocker 23 is in the permitted state and the other 1 st stoppers 52 are in the restricted state. The control unit 40 controls switching so that the 2 nd stopper 53 corresponding to the 3 rd stocker 23 is in the guide state, and the other 2 nd stoppers 53 are in the permission state. The state of the control unit 40 may be switched between the 1 st stopper 52 and the 2 nd stopper 53 based on an electric signal input by the operator by pressing a button provided near the replenishment port 61.

Next, the empty bobbin Bw is replenished from the replenishment port 61 to the paper tube moving path 51 by the operator. At this time, the empty bobbin Bw is disposed between the adjacent spacers 54. The paper tube moving path 51 is sequentially supplemented with a plurality of empty tubes Bw. The empty bobbin Bw inside the paper tube moving path 51 is pushed by the empty bobbin Bw newly replenished to the paper tube moving path 51 from the replenishment port 61 via the spacer 54, thereby moving in the machine body longitudinal direction. At this time, the empty bobbin Bw moves along the machine body length direction together with the spacer 54 and the belt 55.

When the empty bobbin Bw moving in the machine body longitudinal direction in the paper tube moving path 51 reaches the position corresponding to the 3 rd stocker 23 as the replenishment target, the empty bobbin is replenished to the stocker 23 via the guide portion 62 corresponding to the 1 st stop portion 52 in the permitted state by the 2 nd stop portion 53 in the guided state. When the number of empty bobbins Bw in the 3 rd stocker 23 becomes 4 as the maximum number, the control unit 40 controls switching so that the 1 st stopper 52 corresponding to the 3 rd stocker 23 is in the restricted state and the 2 nd stopper 53 corresponding to the 3 rd stocker 23 is in the permitted state. Thereafter, the replenishment of the empty bobbin Bw is stopped until the stocker 23 as a replenishment target of the empty bobbin Bw is generated. When the stocker 23 as the replenishment target of the empty bobbin Bw is generated, the above-described series of operations are performed.

(Effect)

The paper tube replenishment device 50 of the present embodiment includes a paper tube moving path 51, and the paper tube moving path 51 is provided in a plurality of layers corresponding to the multi-layer winding unit 30, and extends in the longitudinal direction of the machine body so that empty bobbins Bw replenished to the plurality of hoppers 23 can move in the longitudinal direction of the machine body. The paper tube moving path 51 includes: a support surface 51a extending along the longitudinal direction of the machine body and supporting the empty bobbin Bw from below; a replenishment port 61 provided at an end portion of the paper tube moving path 51 in the longitudinal direction of the machine body, for replenishing the empty bobbin Bw; and a plurality of guide portions 62 for guiding the empty bobbin Bw moving along the longitudinal direction of the machine body to the plurality of hoppers 23, respectively. According to the above configuration, the empty bobbin Bw replenished to the paper tube moving path 51 from the replenishment port 61 moves in the machine body longitudinal direction in the paper tube moving path 51. Then, the empty bobbin Bw moving in the longitudinal direction of the machine body is conveyed to each stocker 23 via the plurality of guide portions 62. Therefore, the empty bobbin Bw is replenished without the operator moving to each stocker 23. This allows the empty bobbin Bw to be efficiently replenished to each stocker 23 of the plurality of winding units 30 provided in the false twist texturing machine 1.

The paper tube replenishment device 50 of the present embodiment has a plurality of 1 st stoppers 52 provided at positions of the paper tube moving path 51 corresponding to the guide portions 62. The 1 st stopper 52 is switchable between a permitted state in which the empty bobbin Bw is permitted to move from the paper tube moving path 51 to the stocker 23 via the guide 62, and a restricted state in which the empty bobbin Bw is restricted from moving from the paper tube moving path 51 to the stocker 23 via the guide 62. In the above configuration, the 1 st stopper 52 corresponding to the guide 62 for guiding the empty bobbin Bw to the stocker 23 which is the replenishment target of the empty bobbin Bw may be set to the permitted state, and the 1 st stopper 52 corresponding to the guide 62 for guiding the empty bobbin Bw to the stocker 23 which is not the replenishment target of the empty bobbin Bw may be set to the restricted state. This allows the empty bobbin Bw to be selectively replenished to the stocker 23 which is to be replenished with the empty bobbin Bw among the plurality of stockers 23.

The paper tube replenishment device 50 of the present embodiment has a plurality of 2 nd stoppers 53 provided at positions of the paper tube moving path 51 corresponding to the respective guide portions 62. The 2 nd stopper 53 is switchable between an allowable state in which the empty bobbin Bw is allowed to move along the longitudinal direction of the machine body in the paper tube moving path 51, and a guide state in which the empty bobbin Bw is guided to the stocker 23 via the guide 62. When the 2 nd stopper 53 is in the guide state, the empty bobbin Bw is restricted from moving beyond the 2 nd stopper 53 in the longitudinal direction of the machine body. According to the above configuration, the 2 nd stopper 53 corresponding to the guide 62 for guiding the empty bobbin Bw to the stocker 23 to be replenished with the empty bobbin Bw is set in the guide state, and thereby the empty bobbin Bw can be restricted from moving beyond the 2 nd stopper 53 in the longitudinal direction of the machine body. Therefore, the empty bobbin Bw can be restrained from moving to a position corresponding to the hopper 23 which is not the replenishment target in the paper tube moving path 51. The 2 nd stopper 53 in the guide state can appropriately guide the empty bobbin Bw to the stocker 23 to be replenished. This makes it possible to appropriately replenish the empty bobbin Bw to the target stocker 23.

The paper tube replenishment device 50 of the present embodiment includes a plurality of spacers 54, and the spacers 54 make the interval in the machine longitudinal direction of the empty bobbin Bw adjacent to the paper tube moving path 51 equal to the interval in the machine longitudinal direction of the adjacent guide portion 62. In the present embodiment, the other end portion (the end portion on the opposite side to the side where the replenishment port 61 is provided) of the paper tube moving path 51 in the machine body longitudinal direction is closed. Alternatively, the 2 nd stopper 53 in the guide state closes an arbitrary position in the longitudinal direction of the paper tube moving path 51. In this case, the empty bobbin Bw which is not replenished to the stocker 23 among the plurality of empty bobbins Bw which move in the paper tube moving path 51 is conveyed to the one end portion of the paper tube moving path 51 or the position of the 2 nd stopper 53 in the guide state, and stays in the paper tube moving path 51. Then, when the empty bobbin Bw is further replenished to any one of the hoppers 23 in a state where the plurality of empty bobbins Bw stay in the paper tube moving path 51, any one of the empty bobbins Bw stay in the paper tube moving path 51 is replenished to the hopper 23. Here, when a plurality of empty tubes Bw move simultaneously in the paper tube moving path 51, there is a case where the interval between adjacent empty tubes Bw in the arrangement direction becomes narrow. Then, the empty bobbin Bw staying in the paper tube moving path 51 may be present at a position where it cannot be properly guided to the stocker 23 via the guide portion 62. According to the present embodiment, the interval between adjacent empty tubes Bw can be made the same as the interval between adjacent guide portions 62 by the spacers 54. This can prevent the empty bobbin Bw staying in the paper tube moving path 51 from being present at a position where the empty bobbin Bw cannot be properly guided to the stocker 23 via the guide portion 62, and can more reliably replenish the empty bobbin Bw to the stocker 23.

The paper tube replenishment device 50 of the present embodiment includes a belt 55, and a plurality of spacers 54 are attached to the belt 55, and the belt 55 is movable in the longitudinal direction of the machine body in the paper tube moving path 51 and is circulated. In the case where only the spacer 54 is provided, the spacer 54 stays in the paper tube moving path 51 after the empty bobbin Bw moving in the paper tube moving path 51 is replenished to the stocker 23. The worker is required to collect the spacers 54 remaining in the paper tube moving path 51, which is troublesome for the worker. According to the above configuration, the plurality of spacers 54 are attached to the endless belt 55 that is movable in the longitudinal direction of the machine body in the paper tube moving path 51. Therefore, the worker is not required to collect the spacers 54 remaining in the paper tube moving path 51, and the trouble of the worker can be reduced.

In the paper tube replenishment device 50 of the present embodiment, the replenishment port 61 is provided only at one end portion of the paper tube moving path 51 in the longitudinal direction of the machine body. According to the above configuration, since the empty bobbin Bw is only required to be replenished from the replenishment port 61 provided only at one end portion of the paper tube moving path 51, it is easy to replenish the empty bobbin Bw to the paper tube moving path 51 as compared with the case where the empty bobbin Bw is replenished from the replenishment ports 61 provided at both side end portions of the paper tube moving path 51.

In the paper tube replenishment device 50 of the present embodiment, the empty bobbin Bw in the paper tube movement path is pushed by the empty bobbin Bw newly replenished to the paper tube movement path 51 from the replenishment port 61, thereby moving along the machine body longitudinal direction. According to the above configuration, the empty bobbin Bw supplied to the paper tube moving path 51 by the operator presses the adjacent empty bobbin Bw, thereby moving the empty bobbin Bw along the machine body longitudinal direction. Therefore, the empty bobbin Bw of the paper tube moving path 51 can be moved in the longitudinal direction of the machine body without providing a device for moving the empty bobbin Bw in the longitudinal direction of the machine body. Thus, the device as a whole does not need a complicated structure, and the cost of the device can be reduced.

In the paper tube replenishment device 50 of the present embodiment, the paper tube moving path 51 has a cylindrical shape extending along the longitudinal direction of the machine body. According to the above configuration, the empty bobbin Bw moving in the paper tube moving path 51 can be reliably prevented from coming off the paper tube moving path 51 to the outside, and the empty bobbin Bw can be reliably replenished to each stocker 23.

(modification)

A modified example in which the above-described embodiment is modified will be described below. However, the same reference numerals are given to the portions having the same configuration as those of the above-described embodiment, and the description thereof will be omitted as appropriate.

In the present invention, as shown in fig. 6, the paper tube replenishment device 150 may be provided with an empty paper tube automatic feeding device 70, and the empty paper tube automatic feeding device 70 may automatically feed empty paper tubes Bw from the replenishment port 61 into the paper tube moving path 51. For example, the empty paper tube automatic feeding device 70 includes a paper tube box 71, a paper tube path 72, and an automatic feeding device 73. The paper tube box 71 can store a large number of empty tubes Bw. The paper tube path 72 is connected to 3 replenishment ports 61 of the paper tube moving path 51 provided in 3 layers. The automatic feeding device 73 automatically feeds the empty bobbin Bw in the paper tube path 72 to the paper tube moving path 51 via the replenishment port 61. The automatic dispensing device 73 is constituted by, for example, a cylinder or the like. The empty bobbin Bw stored in the paper tube box 71 is conveyed downward through the paper tube path 72. At this time, the axial direction of each hollow tube Bw is aligned so as to coincide with the longitudinal direction of the machine body. The empty bobbin Bw located at the position corresponding to the replenishment port 61 among the empty bobbins Bw conveyed downward through the paper tube path 72 is automatically thrown into the paper tube moving path 51 by the automatic throwing device 73. The connection portion between the paper tube path 72 and the replenishment port 61 is tapered, and the empty bobbin Bw pushed by the automatic feeder 73 as a cylinder is guided to the replenishment port 61 along the tapered surface. According to this configuration, the trouble of the operator can be reduced and the working time can be shortened as compared with the case where the operator puts the empty bobbin Bw into the paper tube moving path 51 by manual work. The paper tube replenishment device 150 includes a positioning plate provided inside the paper tube path 72 to position the empty bobbin Bw at a height position where replenishment can be performed to the replenishment port 61. The positioning plate is movable between a positioning position for positioning the empty bobbin Bw and a retracted position where the empty bobbin Bw does not interfere with downward movement. The empty bobbin Bw positioned by the positioning plate at the positioning position is pushed by the automatic feeding device 73 as an air cylinder, and is replenished to the paper tube moving path 51 through the replenishment port 61.

The automatic empty tube feeding device is not limited to the example shown in fig. 6, and for example, an empty tube Bw may be automatically fed from the replenishment port 61 to the tube moving path 51 by a robot arm or the like.

In the above embodiment, the empty bobbin Bw in the paper tube moving path 51 is pushed by the empty bobbin Bw newly replenished into the paper tube moving path 51 from the replenishment port 61, thereby moving in the machine body longitudinal direction. However, the paper tube moving path 51 may have a conveyor for conveying the empty bobbin Bw in the longitudinal direction of the machine body. The conveying device is, for example, a conveyor provided on the bottom surface of the paper tube moving path 51. The empty bobbin Bw placed on the conveyor is conveyed along the longitudinal direction of the machine body by driving the conveyor. The conveying device may press the empty bobbin Bw in the longitudinal direction of the machine body from the end of the paper tube moving path 51 on the side where the replenishment port 61 is provided by air. Further, the conveying device may suck the empty bobbin Bw in the longitudinal direction of the machine body from the end of the paper tube moving path 51 opposite to the side where the replenishment port 61 is provided by air. According to these configurations, the empty bobbin Bw in the paper tube moving path 51 can be conveyed in the longitudinal direction of the machine body by the conveying device. Therefore, the worker is not required to press the empty bobbin Bw by a manual operation, and the trouble of the worker can be reduced.

In the case where the paper tube moving path 51 includes a conveyor as a conveying device for conveying the empty bobbin Bw in the longitudinal direction of the machine body, a plurality of spacers 54 may be attached to the conveyor. In this case, the conveyor corresponds to the belt of the present invention.

In the above embodiment, the paper tube moving path 51 has a cylindrical shape extending along the longitudinal direction of the machine body. However, the paper tube moving path 51 may have a semicircular cross-sectional shape that is open at the upper side and perpendicular to the longitudinal direction of the machine body. The paper tube moving path 51 may be a flat plate-like member, or may be configured such that side walls are provided on both sides of the flat plate-like member in the machine body width direction.

In the above embodiment, the stocker 23 to be replenished with the empty bobbin Bw is determined by the operator's eyes. However, the stocker 23 to be replenished with the empty bobbin Bw may be determined by a sensor provided in the stocker 23. For example, when the number of empty bobbins Bw stored in the stocker 23 is recognized to be small by the sensor, the stocker 23 is determined as a replenishment target of the empty bobbins Bw. In this case, a signal including information of the stocker 23 as a replenishment target of the empty bobbin Bw is sent from the sensor to the control unit 40. Then, the control unit 40 automatically controls the state switching of the 1 st stopper 52 and the 2 nd stopper 53 based on the signal. The state of the control unit 40 may be switched between the 1 st stopper 52 and the 2 nd stopper 53 based on an electric signal input by the operator by pressing a button provided near the replenishment port 61.

In the above embodiment, the paper tube moving path 51 and the hoppers 23 are connected at positions where the guide portions 62 are formed. However, the paper tube moving path 51 and each hopper 23 may not be connected, and a gap may be provided between the paper tube moving path 51 and the hopper 23. In this case, the guide 62 includes an opening formed in the paper tube moving path 51 and a path connecting the paper tube moving path 51 and the hopper 23.

In the above embodiment, the paper tube replenishment device 50 has the belt 55 to which the plurality of spacers 54 are attached. However, the paper tube replenishment device 50 may not have the belt 55. In this case, the spacers 54 each independently are disposed between adjacent empty tubes Bw of the paper tube moving path 51. In this case, the spacers 54 remaining in the paper tube moving path 51 are appropriately collected by the operator. Furthermore, the paper tube replenishment device 50 may be provided without the spacer 54. In this case, a conveyor is preferably provided on the bottom surface of the paper tube moving path 51. By adjusting the positions of the empty tubes Bw arranged on the conveyor, the intervals in the longitudinal direction of the bodies of the adjacent empty tubes Bw in the paper tube moving path 51 can be made the same as the intervals in the longitudinal direction of the bodies of the adjacent guide portions 62.

In the above embodiment, the paper tube replenishment device 50 has a plurality of 1 st stoppers 52 and a plurality of 2 nd stoppers 53. However, the paper tube replenishment device 50 may have only one of the 1 st stopper 52 and the 2 nd stopper 53. When only the 1 st stopper 52 and the 1 st stopper 52 of the 2 nd stoppers 53 are provided, the empty bobbin Bw supplied from the supply port 61 to the paper tube moving path 51 is supplied to the stocker 23 corresponding to the 1 st stopper 52 in the permitted state, and is not supplied to the stocker 23 corresponding to the 1 st stopper 52 in the restricted state. In this case, a conveyor is preferably provided on the bottom surface of the paper tube moving path 51. When the empty bobbin Bw moving in the paper tube moving path 51 reaches a position corresponding to the guide part 62 guiding the empty bobbin Bw to the stocker 23 as a replenishment object, the operation of the conveyor is stopped, whereby the empty bobbin Bw can be properly guided to the stocker 23.

When only the 2 nd stopper 53 of the 1 st stopper 52 and the 2 nd stopper 53 is disposed, the empty bobbin Bw supplied from the supply port 61 to the paper tube moving path 51 is supplied to the stocker 23 corresponding to the 2 nd stopper 53 in the guide state and the stocker 23 located on the supply port 61 side in the machine body longitudinal direction with respect to the stocker 23. When only the 2 nd stopper 53 is disposed, the empty bobbin Bw fed from the feeding port 61 to the paper tube moving path 51 is not fed to the hopper 23 located on the opposite side of the feeding port 61 in the longitudinal direction of the body from the hopper 23 corresponding to the 2 nd stopper 53 in the guide state. In this case, it is preferable that the paper tube moving path 51 is provided with a pushing mechanism for pushing out the empty bobbin Bw in the paper tube moving path 51 toward the stocker 23. The empty bobbin Bw reaching the position where the 2 nd stopper 53 in the guide state exists is pushed out toward the stocker 23 by the push-out mechanism, and is thereby replenished into the stocker 23. In the configuration having the push-out mechanism, a movement preventing member may be provided in the paper tube moving path 51, and the movement preventing member may restrict the empty bobbin Bw in the paper tube moving path 51 from naturally moving toward the stocker 23 by the guide portion 62 which is opened obliquely downward. The empty bobbin Bw pushed out by the push-out mechanism passes over the movement preventing member to reach the stocker 23.

Further, in the case where only the 2 nd stopper 53 of the 1 st stopper 52 and the 2 nd stopper 53 is provided, the guide 62 may be switchable between an upward state in which it is opened upward and a downward state in which it is opened obliquely downward so as to be directed toward the stocker 23. In this case, when the empty bobbin Bw moving in the paper tube moving path 51 reaches a position corresponding to the guide part 62 for guiding the empty bobbin Bw to the stocker 23 as a replenishment target, the guide part 62 is placed in a downward state. Thereby, the empty bobbin Bw in the paper tube moving path 51 moves toward the stocker 23 by the guide part 62. When the empty bobbin Bw moving in the paper tube moving path 51 is at a position corresponding to the guide part 62 guiding the empty bobbin Bw to the stocker 23 which is not the replenishment object, the guide part 62 is in an upward state. Thereby, the empty bobbin Bw cannot move toward the stocker 23 by the guide portion 62. For example, the paper tube moving path 51 can be rotated about a rotation axis extending along the longitudinal direction of the machine body to switch between the upward state and the downward state.

In the present invention, the paper tube replenishment device 50 may be configured without any of the 1 st stopper 52 and the 2 nd stopper 53. In this case, when there are a plurality of hoppers 23 to be replenished with empty tubes Bw, the empty tubes Bw supplied from the replenishment port 61 to the paper tube moving path 51 are replenished in sequence from the hopper 23 located closest to the replenishment port 61. In this case, the stocker 23 storing the largest number of empty bobbins Bw prevents the new empty bobbin Bw from being replenished to the stocker 23 by the empty bobbin Bw stored last in the stocker 23. For example, in the stocker 23 in which the maximum number of empty bobbins Bw is 4, the 4 th empty bobbin Bw stored in the stocker 23 prevents new empty bobbins Bw from being replenished to the stocker 23 for the stocker 23 in which 4 empty bobbins Bw are stored.

In the above embodiment, the paper tube moving path 51 has a cylindrical shape. However, the paper tube moving path 51 is not limited to a cylindrical shape. For example, the paper tube moving path 51 may have a trapezoid or square shape when viewed from the longitudinal direction of the machine body. The paper tube moving path 51 may be configured to have a support surface extending in the longitudinal direction of the machine body and supporting the empty bobbin Bw from below, and a wall portion extending in the longitudinal direction of the machine body and connected to both end portions of the support surface in the width direction of the machine body, and the paper tube moving path 51 may be opened at the upper side. In this case, the height of the wall portion in the up-down direction is preferably longer than the diameter of the hollow bobbin Bw. Specifically, the paper tube moving path 51 may be in a shape of a "コ" or a "U" or a "wire" when viewed in the longitudinal direction of the machine body.

In the above embodiment, a total of 12 winding devices 21 of 3 layers 4 rows are provided on the winding bed 9 included in one span. However, the winding device 21 is not limited to the arrangement of the above embodiment. For example, a total of 16 winding devices 21 of 4 layers and 4 rows may be provided on the winding stand 9 included in one span, and a total of 20 winding devices 21 of 5 layers and 4 rows may be provided.
