Disclosure of Invention

In the yarn winding machine of patent document 1, the yarn threading member is guided by a guide rail and moved in a predetermined direction inclined at a predetermined angle to the arrangement direction. Therefore, the moving direction of the threading member is not easily deviated, and threading error is not easily generated. Moreover, the threading operation is facilitated, and the work efficiency is improved.

However, in the case of applying the structure of patent document 1 to a yarn winding machine such as patent document 2 to yarn winding, there is room for improvement in the following respects. That is, in the yarn winding machine having 2 yarn winding portions as in patent document 2, after the yarn threading member is moved along the guide rail with respect to one yarn winding portion to thread the yarn, it is necessary to thread the yarn in the other yarn winding portion by performing the same operation. Therefore, from the viewpoint of simplification of the yarn winding step, it is desirable to wind 2 yarns at a time.

The invention aims to provide a yarn winding machine which can simultaneously start yarn guide of 2 yarn winding parts.

The yarn winding machine according to claim 1 is characterized by comprising: 2 filament winding portions each having: a bobbin holder to which a plurality of bobbins are attached in an axial direction thereof, a plurality of thread guides arranged in the axial direction of the bobbin holder so as to correspond to the plurality of bobbins, respectively, and a guide rail extending in a direction inclined with respect to an arrangement direction of the thread guides, the 2 thread winding parts being arranged in a direction orthogonal to the arrangement direction, and a thread winding member to wind a thread onto the thread guides of the 2 thread winding parts;

the guide rails of the 2 filament winding portions extend obliquely to opposite sides of each other with respect to the arrangement direction; the thread-up member has: and 2 yarn holding portions provided corresponding to the 2 yarn winding portions, each holding a plurality of the yarns in an opened state, and slidably engaged with the guide rail, and a support portion supporting the 2 yarn holding portions so as to be able to move closer to and away from each other.

Each of the 2 yarn winding portions includes a plurality of yarn guides and a guide rail extending in a direction inclined with respect to the arrangement direction of the yarn guides (the axial direction of the bobbin holder). In the present invention, "inclined with respect to the alignment direction" means intersecting the alignment direction at an angle of less than 90 degrees, except for a form in which the guide rails are parallel to the alignment direction or a form in which the guide rails are orthogonal to the alignment direction. On the other hand, each of the 2 yarn holding portions of the thread spinning-in member holds the plurality of yarns wound by the corresponding yarn winding portion in an opened state. And, 2 wire holding parts are supported to be able to come close to/come away from.

In a state where a plurality of yarns are held by each of the yarn holding portions, 2 yarn holding portions are slidably engaged with the guide rail of the corresponding yarn winding portion. The 2 guide rails extend obliquely to the opposite side to each other with respect to the arrangement direction. In this state, the threading member is moved in the arrangement direction of the yarn guides. Among them, since the 2 wire holding portions are supported by the support portion so as to be able to move closer to and away from each other, the 2 wire holding portions move along the guide rail in a direction inclined to the arrangement direction of the wire guides while being separated from each other. Thereby, the plurality of yarns held by the yarn holding portions are caught by the plurality of yarn guides of the corresponding yarn winding portions. According to the present invention, the yarn can be simultaneously threaded onto the yarn guides of the 2 yarn winding portions on both sides by moving the yarn threading member once in the arrangement direction, and therefore, the yarn threading operation can be simplified.

The yarn winding machine according to claim 2 is characterized in that, in addition to the above-described aspect 1, the thread winding member includes a handle connected to the support portion and extending in the arrangement direction.

When the number of the yarn guides arranged (that is, the number of the bobbins) is large, it is necessary to move the yarn feeding member long in the arrangement direction when feeding the yarn to the yarn guide. In this regard, in the present invention, since the threading member has the handle extending forward from the support portion, it becomes easy to move the threading member to a remote place by gripping the handle.

The yarn winding machine according to claim 3 is characterized in that, in addition to the above-described aspect 1 or 2, the yarn holding portion has an engaging portion that engages with the guide rail at an outer end portion that is distant from the other yarn holding portion.

If the thread holding portions have engaging portions at outer ends of the thread holding portions, the thread holding portions are likely to move in a direction orthogonal to the arrangement direction when the thread feeding members move in the arrangement direction.

A yarn winding machine according to claim 4 is characterized in that, in any one of the above-described aspects 1 to 3, the plurality of yarn guides are movable between a winding position at which the plurality of yarns are wound around the plurality of bobbins respectively and a threading position at which the plurality of yarn guides are gathered to an end portion side in the arrangement direction at intervals smaller than the winding position.

Since the plurality of yarn guides can be gathered to the end portion side in the arrangement direction, the amount of movement of the yarn threading member in the arrangement direction can be reduced when yarn threading is performed to the yarn guides, and yarn threading becomes easy.

A yarn threading member according to claim 5 of the present invention is a yarn threading member for threading a yarn onto a plurality of yarn winding portions each having a bobbin holder to which a plurality of bobbins are attached in an axial direction thereof, a plurality of yarn guides arranged in the axial direction of the bobbin holder so as to correspond to the plurality of bobbins, respectively, and a guide rail extending in a direction inclined with respect to an arrangement direction of the yarn guides, the guide rail extending in a direction inclined to the opposite side to the arrangement direction, the yarn threading member comprising:

comprising: 2 yarn holding portions provided corresponding to the 2 yarn winding portions, holding the plurality of yarns in an opened state, and slidably engaging with the guide rail, and a support portion supporting the 2 yarn holding portions so as to be able to move closer to and away from each other.

Each of the 2 yarn holding portions is slidably engaged with the guide rail of the corresponding yarn winding portion in a state where a plurality of yarns are held. In this state, the thread-up member is moved in the direction of arrangement of the thread guides. Wherein after the 2 wire holding parts are supported by the supporting part so as to be able to approach/separate from each other, the 2 wire holding parts move away from each other along the guide rail. Thereby, the plurality of yarns held by the respective yarn holding portions are caught by the plurality of yarn guides of the corresponding yarn winding portions.

A yarn threading method of a yarn winding machine according to claim 6 is a yarn threading method of a yarn winding machine according to any one of claims 1 to 4, in which a yarn is threaded onto the yarn guide of the 2 yarn winding sections using the yarn threading member, and the method includes:

a thread holding step of holding the plurality of threads in an opened state on the 2 thread holding portions of the thread winding-up member, an engaging step of slidably engaging the thread holding portions with a portion of the guide rail on one side in the arrangement direction with respect to the thread guides, and a thread winding-up step of moving the support portion to the other side in the arrangement direction to move the 2 thread holding portions along the guide rail, respectively, and thereby winding up the threads onto the thread guides of the 2 thread winding-up portions.

In the present invention, a plurality of wires are first held to each of 2 wire holding portions, and then the 2 wire holding portions are slidably engaged to the guide rails of the corresponding wire winding portions. Then, the thread-up member is moved in the direction of arrangement of the thread guides. Wherein since the 2 wire holding portions are relatively movable in a direction orthogonal to the arrangement direction, the respective wire holding portions are relatively movable in the orthogonal direction and are moved along the guide rail. Thereby, the plurality of yarns held by the respective yarn holding portions are caught by the plurality of yarn guides of the corresponding yarn winding portions.

Detailed Description

Embodiments of the present invention are explained below. The directions of the spinning draft device shown in fig. 1 and 2 are defined as the front, rear, left, right, up and down directions, and these directional terms are used as appropriate for the following description.

(general construction of spinning draft apparatus)

As shown in fig. 1 and 2, the spinning and drawing apparatus 1 includes 2 godet rolls 3 and 4, a yarn winding machine 5, a control device 6, and the like.

A spinning machine 2 is disposed above the spinning draft device 1. The spinning machine 2 spins a yarn Y of synthetic fiber from each of a plurality of spinnerets (not shown).

The 2 godet rolls 3 and 4 are disposed below the spinning machine 2 in a posture in which the axial direction is parallel to the left-right direction. The yarn Y spun from the spinning machine 2 is wound around a godet roller 3 and a godet roller 4 in this order. The 2 godet rollers 3 and 4 are supported by an elongated support member 7 extending obliquely rearward and upward from a position above the front end of the yarn winding machine 5.

The godet roller 3 on the upstream side in the yarn running direction is attached to the tip end of the support member 7. The other godet roller 4 is mounted on a support member 7 so as to be movable in the longitudinal direction thereof. The position of the godet roller 4 is switched between a front position indicated by a two-dot chain line and a rear position indicated by a solid line in fig. 2 by a lift motor, not shown. As will be described later, the godet roller 4 is located at the front side when the yarn is fed, and at the rear side when the yarn is wound by the yarn winding machine 5.

The 2 godet rollers 3 and 4 are respectively rotated and driven by a drive motor (not shown). The plurality of yarns Y spun from the spinning machine 2 are fed to the yarn winding machine 5 by the 2 godet rollers 3 and 4. As shown in fig. 2, a yarn restricting guide 8 is provided on the yarn advancing direction upstream side of the godet roller 3, and a yarn restricting guide 9 is also provided on the yarn advancing direction upstream side of the godet roller 4.

The yarn winding machine 5 includes 2 winding units 10 (corresponding to the yarn winding unit of the present invention). The 2 winding units 10 are arranged in the left-right direction and are disposed so as to sandwich a plurality of yarn paths of the yarn Y fed from the godet rollers 3 and 4 above. The 2 winding units 10 are arranged symmetrically. The plurality of yarns Y spun from the spinning machine 2 are separately fed to 2 winding units 10. For example, when 24 yarns Y are fed from the spinning machine 2, half of the yarns Y, 12 yarns Y, are wound by the left winding unit 10, and the remaining 12 yarns Y are wound by the right winding unit 10.

Each winding unit 10 includes a support frame 11, a turn table 12, and 2 bobbin holders 13. The support frame 11 is supported by the body 14 in a horizontal posture. The turntable 12 is a disk-shaped member and is rotatably attached to the body 14. The 2 bobbin holders 13 extending in the front-rear direction are supported in a cantilever state on the turn table 12. A plurality of (for example, 12) bobbins B are mounted on each bobbin holder 13 in the axial direction thereof. Each bobbin holder 13 is rotationally driven by a motor, not shown. When the turn table 12 rotates, the positions of the 2 bobbin holders 13 supported on the turn table 12 are switched up and down.

Each winding unit 10 includes a plurality of guide units 15, a plurality of traverse guides 16, and a contact roller 17.

As shown in fig. 1 to 3, a guide support 19 that is long in the front-rear direction is provided above the support frame 11. A guide rail 20 extending in the front-rear direction is fixed to the guide support body 19. A plurality of guide units 15 are attached to the guide rail 20 so as to be movable in the front-rear direction.

The plurality of guide units 15 have a plurality of fulcrum guides 21 (thread guides of the present invention) corresponding to the plurality of bobbins B, respectively. The structure of the guide unit 15 will be described in detail later.

The plurality of traverse guides 16 are attached to the support frame 11 and arranged below the plurality of guide units 15. The yarn Y hooked on the fulcrum guides 21 of the guide units 15 is traversed forward and backward by the traverse guide 16 using the fulcrum guides 21 as fulcrums. The traversed yarn Y is wound around the bobbin B attached to the rotating bobbin holder 13 to form a package P.

The contact roller 17 is rotatably supported on the lower portion of the support frame 11. The contact roller 17 rotates while applying a predetermined contact pressure to the package P when winding the yarn around the bobbin B, thereby carding the shape of the package P.

When a full package P is formed on the bobbin holder 13 located at the upper position, the turn table 12 rotates to switch 2 bobbin holders 13. That is, the bobbin holder 13 located at the lower position moves to the upper position, and the yarn Y is wound around the bobbin B attached to the bobbin holder 13. Then, the bobbin holder 13 around which the full package P is wound moves to the lower position, and the full package P is taken off at the lower position.

The control device 6 shown in fig. 2 is a device that serves to control the entire spinning draft device 1. Specifically, the control device 6 sends control signals to each part of the spinning draft device 1, such as motors for driving the godet rollers 3 and 4, a motor for lifting the godet roller 4, and a control unit 18 of the yarn winding machine 5.

(details of the guide unit)

As shown in fig. 3 and 4, each guide unit 15 includes a guide holding member 22, a fulcrum guide 21 attached to the guide holding member 22, an upper guide 23, and a lower guide 24.

The guide holding member 22 is attached to the guide rail 20 so as to be movable in the front-rear direction. Further, a cylinder (not shown) for driving the plurality of guide units 15 in the front-rear direction is attached to the guide holding member 22. Thus, the plurality of guide units 15 can move between the winding positions (see fig. 2 and 12) arranged in a dispersed manner in the front-rear direction and the threading positions (see fig. 7 and 10) at which the distance from the front-rear direction is smaller than that of the winding positions and the leading ends are concentrated on the leading end side.

The fulcrum guide 21 has a cylindrical shape so that its axial direction is parallel to the left-right direction and is attached to the guide holding member 22. The fulcrum guide 21 is a guide that serves as a fulcrum when the yarn Y is traversed by the traverse guide 16. As shown in fig. 2, for each of the plurality of fulcrum guides 21, the wire Y is hung on the side outside the fulcrum guide 21. That is, as shown in fig. 4(a), in the guide unit 15(15a) located on the rear side, the wire Y is hung on the side surface on the rear side of the fulcrum guide 21. As shown in fig. 4(b), the front guide unit 15(15b) has the wire Y hooked on the front side surface of the fulcrum guide 21. As will be described in detail later, the threading to the plurality of guide units 15 (fulcrum guides 21) is performed by moving all the yarns Y from the rear to the front using the threading member 26 (see fig. 8).

The upper guide 23 is a U-shaped guide disposed above the fulcrum guide 21, and is disposed with the opening of the U-shape directed rearward. The thread Y extending from the rear to the fulcrum guide 21 enters the upper guide 23 through the opening. The upper guide 23 restricts the movement of the yarn Y in the left-right direction.

Further, in order to move all the yarns Y from the rear to the front, and to hook the yarns Y to the rear side surface with respect to the rear fulcrum guide 21 and to hook the yarns Y to the front side surface with respect to the front fulcrum guide 21, the following points must be noted. First, the guide unit 15a located on the rear side needs to prevent the wire Y from moving forward relative to the fulcrum guide 21. On the other hand, the guide unit 15b located on the front side needs to make the wire Y moved from the rear turn to the front of the fulcrum guide 21.

Therefore, a lower guide 24 is disposed below each fulcrum guide 21. As shown in fig. 4, the lower guide 24 is a hook-shaped guide having a hook-shaped tip portion. However, the orientation of the lower guide 24 is different between the rear guide unit 15a and the front guide unit 15 b.

As shown in fig. 4(a), the lower guide 24 of the rear guide unit 15a has a hook-shaped distal end portion directed rearward. Thus, the thread Y moved from the rear side enters the lower guide 24, and is restricted from moving outward by the hook-shaped distal end portion. On the other hand, as shown in fig. 4(b), the lower guide 24 of the front guide unit 15b has a hook-shaped distal end portion directed to the front side. The thread Y moved from the rear side moves forward along the outer edge of the lower guide 24 around the fulcrum guide 21, and then enters the lower guide 24.

As shown in fig. 1 and 3, the plurality of guide units 15 of the 2 winding units 10 arranged in 2 rows are disposed such that the distal ends of the fulcrum guides 21 face inward, respectively. Further, by moving the threading member 26 described later forward and backward between the 2 winding units 10, threading can be simultaneously performed on all the guide units 15 arranged in 2 rows.

(structure for spinning-in)

Next, a structure for hanging a plurality of yarns Y on the plurality of guide units 15 will be described. In fig. 5, in order to clearly show the guide rail 25, the plurality of guide units 15 and the thread-up member 26 arranged on the guide rail 25 are shown by imaginary lines.

As shown in fig. 3 and 5, each winding unit 10 has a guide rail 25 extending obliquely with respect to the front-rear direction, which is the arrangement direction of the guide units 15. The guide rail 25 is fixed to a portion of the guide support body 19 below the plurality of guide units 15 (on the paper-side in fig. 5). The rear end of the guide rail is located behind the guide units 15 and is exposed from the guide units 15. The guide rails 25 of the 2 winding units 10 are arranged symmetrically and inclined to opposite sides with respect to the front-rear direction. That is, the 2 guide rails 25 extend obliquely outward with respect to the front-rear direction so as to be spaced apart from each other toward the front. A guide groove 25a extending in the extending direction of each guide rail 25 is formed.

As shown in fig. 6, the thread-cutting member 26 has 2 thread-holding portions 30(30a, 30b), a support portion 31, and a handle 32. The 2 yarn holding portions 30 correspond to the left and right 2 winding units 10, respectively. Each of the 2 yarn holding portions 30 is formed with a plurality of opening grooves 33 for holding the plurality of yarns Y wound around the corresponding winding unit 10 in an opened state. As shown in fig. 6(a), the plurality of loosening grooves 33 formed in the 2 thread holding portions 30 are arranged in a fan shape extending from the distal end side of the thread hooking member 26 to the near side (the handle 32 side). The thread holding portion 30 has 2 engaging portions 34 protruding toward the rear surface side (the side toward the paper surface in fig. 6) of the thread holding portion 30 at the outer end portions in the left-right direction. The engaging portion 34 slidably engages with the guide groove 25a of the guide rail 25. Thereby, the 2 thread holding portions 30 of the thread winding member 26 are detachable from at least the rear end portion of the guide rail 25.

The support portion 31 has a guide portion 35 fixed to the proximal end portion of the left thread holding portion 30a and a slide portion 36 fixed to the proximal end portion of the right thread holding portion 30 b. The slide portion 36 is engaged with the guide portion 35 so as to be slidable in the left and right directions. Thereby, the right thread holding portion 30b can move relative to the left thread holding portion 30 a. That is, the 2 thread holding portions 30 are configured to be movable relative to each other in the left-right direction between a state in which the 2 thread holding portions 30 on the left and right sides in fig. 6(a) are in contact with each other and a state in which the 2 thread holding portions 30 on the left and right sides in fig. 6(b) are separated from each other.

The handle 32 is a rod-shaped member extending in the front-rear direction. The handle 32 has a distal end connected to the guide 35.

As will be described later, when threading the yarn Y to the guide unit 15, the threading member 26 is moved forward between the 2 winding units 10 as shown in fig. 5 while the yarn Y wound by the 2 winding units 10 is held by the 2 yarn holding portions 30 of the threading member 26.

(birth work)

Next, the yarn threading operation for threading the plurality of yarns Y spun from the spinning machine 2 onto the spinning and drawing device 1 and the operation of the spinning and drawing device 1 at this time will be described with reference to fig. 7 to 12.

In the case of a threading operation, an operator stands in front of the yarn winding machine 5 to perform the operation. First, the operator inputs a command for preparing a yarn threading from an operation unit (not shown) of the spinning draft device 1.

When a preparation-spinning-end command is input, the control device 6 causes the spinning draft device 1 to perform the spinning preparation operation described below. First, from a state where the godet roller 4 is located at the rear position, the godet roller 4 is lowered by the lifting motor and moved to the front position near the godet roller 3. All the guide units 15 are moved to the threading positions by the air cylinders and are collectively arranged on the front side.

When the preparation operation for spinning is completed in the spinning draft device 1, the operator sucks and holds the plurality of yarns Y coming down from the spinning machine 2 above with the suction gun 40. At this time, all the yarns Y wound by the 2 winding units 10 (for example, 12 yarns per unit, 24 yarns in total) are sucked by the suction gun 40. Then, the operator operates the suction gun 40 to sequentially thread the plurality of yarns Y onto the 2 godet rollers 3 and 4 disposed above the front end portion of the yarn winding machine 5 and close to each other.

After the end of the threading onto the 2 godets 3, 4, the plurality of threads Y are hung onto each of the plurality of guide units 15. The threading of the guide unit 15 is performed using the threading member 26. First, at a stage before threading to the guide unit 15, the threading member 26 is taken out from the guide rail 25. In this state, the operator inserts the plurality of yarns Y positioned between the godet roller 4 and the suction gun 40 of fig. 7 from the front into the 2 yarn holding portions 30 of the thread winding member 26 while gripping the handle 32 of the thread winding member 26. Thereby, the plurality of yarns Y are inserted into the plurality of loosening grooves 33 of the 2 yarn holding portions 30 one by one, and held on the yarn holding portions 30 in a loosened state (yarn holding step). At this time, since the plurality of yarns Y are sucked by the suction gun 40 in front, tension acts on the yarns Y held by the yarn holding portion 30, and the yarns Y do not come out of the opening groove 33 at any time.

Next, as shown in fig. 8, the operator attaches the threading member 26 to the rear end portions of the 2 guide rails 25. More specifically, the engaging portions 34 of the 2 wire holding portions 30 of the thread hooking member 26 are engaged with the end portions of the guide grooves 25a of the 2 guide rails 25 on the rear side of the plurality of guide units 15 (engaging step). As shown in fig. 9, after being engaged with the guide rail 25, the operator grips the handle 32 to draw the threading-in member 26 toward the near side (front side). Among them, the 2 thread holding portions 30 are supported by the supporting portions 31 so as to be movable relative to each other in the left-right direction. Therefore, the 2 wire holding portions 30 are separated from each other in the left-right direction below the plurality of guide units 15, and move along the 2 guide rails 25 inclined so as to expand forward.

The plurality of threads Y held in the opened state by the thread holding portions 30 are guided to the plurality of guide units 15 arranged in 1 row as shown in fig. 10 and are hung by moving the thread holding portions 30 in a direction inclined to the arrangement direction of the guide units 15 along the corresponding guide rails 25 (threading step). Then, the 2 thread holding portions 30 of the thread take-up member 26 move along the 2 guide rails 25, and the thread Y is simultaneously hung on the 2 left and right rows of guide units 15.

After the end of the spinning to the guide unit 15, the operator then inputs a command to prepare for winding from the operation unit of the spinning draft device 1. When a command to prepare winding is input, the control device 6 causes the spinning draft device 1 to perform the winding preparation operation described below. First, as shown in fig. 11, the godet roller 4 is retracted and raised from the front position to the rear position by the lifting motor. Then, as shown in fig. 12, the plurality of guide units 15 are moved from the threading positions to the winding positions by the air cylinders and are unwound.

In the present embodiment, the guide rails 25 of the 2 winding units 10 extend obliquely to the opposite sides with respect to the arrangement direction of the guide units 15 (the axial direction of the bobbin holder 13). On the other hand, each of the 2 yarn holding portions 30 of the thread take-up member 26 holds the plurality of yarns Y wound by the corresponding yarn winding portion in an opened state. The 2 wire holding portions 30 are supported so as to be movable relative to each other in a direction orthogonal to the arrangement direction of the guide units 15. That is, the 2 thread holding portions 30 are supported by the support portion 31 so as to be able to approach and separate.

In a state where a plurality of yarns Y are held by the respective yarn holding portions 30, 2 yarn holding portions 30 are slidably engaged with the guide rail 25 of the corresponding winding unit 10. In this state, if the thread-threading member 26 is moved forward in the direction in which the 2 guide rails 25 are extended, the 2 thread holding portions 30 are moved in the left-right direction in an extended manner and are moved along the 2 guide rails 25. Thereby, the plurality of yarns Y held by the respective yarn holding portions 30 are hooked on the plurality of guide units 15 of the corresponding winding unit 10. In the present embodiment, the thread Y can be simultaneously caught by the guide units 15 of the 2 winding units 10 on both sides by moving the thread feeding member 26 forward once, and therefore, the thread feeding operation can be simplified.

When the number of the guide units 15 arranged (that is, the number of the bobbins B) is large, the thread-up member 26 needs to be moved long in the front-rear direction at the time of thread-up. That is, the operator positioned at the front needs to move the threading-up member 26 to the very rear side. In this regard, since the threading member 26 of the present embodiment has the handle 32 extending forward from the support portion 31, it becomes easy to move the threading member 26 to the depth side by gripping the handle 32.

In the present embodiment, the yarn holding portion 30 has an engaging portion 34 that engages with the guide rail 25 at the outer end portion in the left-right direction. Therefore, when the thread hooking member 26 is moved forward with the engaging portion 34 engaged with the guide rail 25, the 2 thread holding portions 30 are easily moved leftward and rightward.

In the present embodiment, the plurality of guide units 15 are movable between the winding position and the threading position at which the leading ends are gathered at a smaller interval than the winding position. That is, since the plurality of guide units 15 can be concentrated on the front side at the time of the threading, the amount of movement of the threading member 26 in the front-rear direction can be small, and the threading is easy.

Next, a modified form in which various modifications are applied to the above embodiment will be described. However, the same reference numerals are given to portions having the same configurations as those of the above-described embodiment, and the description thereof is omitted as appropriate.

1) As shown in fig. 13, the support portion 51 of the thread-start member 46 may have a configuration including a guide portion 55 and 2 sliding portions 56 provided to the 2 thread holding portions 30. The handle 32 is attached to the guide portion 55. That is, the 2 wire holding portions 30 can move in the left-right direction with respect to the guide portion 55 to which the handle 32 is connected.

After the 2 thread holding portions 30 are engaged with the 2 guide rails 25, if the thread leading member 46 is pulled toward the near side by the grip handle 32, the 2 thread holding portions 30 move to the right and left with respect to the guide portion 55, and move in the oblique direction along the 2 guide rails 25.

2) The guide for hooking the yarn Y with the thread hooking member 26 is not limited to the structure of the above embodiment. For example, the upper guide 23 and the lower guide 24 are not necessary. For example, in the case where the fulcrum guide itself has a shape or the like that can prevent the wire Y from falling off, at least one of the upper guide 23 and the lower guide 24 can be omitted.

3) Although the operator operates the thread feeding member 26 to hang the thread Y on each of the plurality of guide units in the foregoing embodiment, the thread feeding member 26 may be operated by a thread feeding robot.
