Description

Technical Field

[0001] One aspect of the present invention relates to a joint processing device and a wire feeding device. Background Technology

[0002] A known false-twisting machine performs false-twisting on multiple synthetic fiber filaments supplied from a yarn feed package, and then winds the processed synthetic fiber filaments into a take-up package in a take-up device. For example, Patent Document 1 (Japanese Patent Publication No. 7-68010) discloses a false-twisting machine that includes a yarn feed frame holding multiple yarn feed packages and a twisting device for performing false-twisting on the filaments supplied from the yarn feed packages. In such a yarn feed frame, a splicing process (tail splicing process) is performed to connect the synthetic fiber filaments of the yarn feed package supported by one bobbin to the synthetic fiber filaments of the yarn feed package supported by another bobbin. As a result, even if the synthetic fiber filaments in one yarn feed package are exhausted, synthetic fiber filaments are supplied from another yarn feed package, thus enabling a continuous supply of synthetic fiber filaments to the twisting device.

[0003] In the above-described splicing process, threads are drawn from two feed rolls and connected using a twister. At the end of this connection, the connected thread portions between the feed rolls are left in a relatively slack state. If one feed roll becomes empty under unchanged conditions, when the slack thread portion between the rolls is fed towards the processing section, damage or breakage may occur due to localized load applied to that portion or contact with surrounding components. To avoid this, after connecting the threads using the twister, the operator locks the thread portion between the rolls at a designated locking position on the feed frame, and while in this locked state, rotates one or both feed rolls in the direction that stretches the thread portion, thereby eliminating slack.

[0004] Currently, research is underway to automate a series of actions, including guiding and setting yarns from two yarn feed spools to a twister, connecting these yarns together via the twister, and securing the connected yarns at the locking point. However, to ensure the yarns move smoothly and reliably at the locking point, a strong grip is required in the holding part to prevent yarn movement, which can damage the gripped portion. On the other hand, when holding the yarn in a way that avoids damage, such as by hooking it onto a hook, irregular slack in the yarn makes it difficult for the yarn ends to move smoothly, and the securing to the locking part is prone to failure. Summary of the Invention

[0005] Therefore, one objective of the present invention is to provide a splicing device and a wire feeding device that can maintain the quality of the wire while improving the accuracy of the operation, and can automate a series of actions including splicing and wire hanging.

[0006] One aspect of the present invention relates to a splicing device for connecting the end of a first feed yarn package mounted on a yarn feeder to the end of a second feed yarn package, and for securing the connected yarn to at least one locking portion provided on the yarn feeder. The splicing device comprises: a suction holding portion for holding the yarn by attracting it; a moving portion for moving the suction holding portion; a connecting portion for connecting the end of the first feed yarn package to the end of the second feed yarn package; and a control portion for controlling the suction holding portion, the moving portion, and the connecting portion. The control portion controls the suction holding portion, the moving portion, and the connecting portion to perform splicing processing. The splicing processing includes: a first setting operation, in which the suction holding portion holds the end of the first feed yarn package, and the moving portion moves the suction holding portion so that the end of the first feed yarn package is positioned at the connecting portion; and a second setting operation. The suction holding part holds the end of the second feed yarn package, and the moving part moves the suction holding part so that the end of the second feed yarn package is set at the connecting part; and the connecting operation, after the first setting operation and the second setting operation, connects the end of the first feed yarn package to the end of the second feed yarn package through the connecting part, and the control part controls the suction holding part and the moving part to perform the yarn hanging process, which includes at least one of the following operations: a first yarn hanging operation, before the first setting operation, the suction holding part holds the end of the first feed yarn package, and the moving part moves the suction holding part so that the yarn of the first feed yarn package is locked at the locking part; a second yarn hanging operation, before the second setting operation, the suction holding part holds the end of the second feed yarn package, and the moving part moves the suction holding part so that the yarn of the second feed yarn package is locked at the locking part.

[0007] The wire ends of the first and second wire feed rolls mentioned here refer not only to the front end of the wire but also to the portion of the wire with a predetermined length centered on that front end. Furthermore, a wire feed frame is provided in the wire feed section of the wire processing device, supporting multiple wire feed rolls. Wire supplied to the processing section of the wire processing device is wound onto the wire feed rolls. In this splicing device, unlike the conventional work sequence performed by the operator, the wire is pre-loaded onto the locking section before splicing. Then, the wires of the first and second wire feed rolls, held by the suction holding section, are always subject to attraction in the suction direction, thus applying tension to the portion of the wire extending from the wire feed roll to the suction holding section. The moving section allows the tensioned wire ends to move, thus enabling more precise wire movement compared to moving irregularly slack wire ends, allowing for high-precision wire loading onto the locking section. Furthermore, since the wire is held by suction, wire damage that occurs when gripping is not performed. Furthermore, when the ends of the first and second feed rolls are connected by attraction and holding, the threads can be damaged because they are attracted by the attraction and holding part while partially bent. However, in this configuration, since the ends of both the first and second feed rolls are attracted and held, such bending does not occur. Therefore, even when the threads are held by the attraction and holding part, they will not be damaged. As a result, it is possible to maintain thread quality and improve operational accuracy, while simultaneously automating a series of operations, including splicing and thread hanging.

[0008] In one embodiment of the present invention, the connector processing device may include a first locking part and a second locking part. The first wire-hanging action is to move the suction and holding part so as to lock the first wire-feeding roll at the first locking part. The second wire-hanging action is to move the suction and holding part so as to lock the second wire-feeding roll at the second locking part.

[0009] In this splice handling device, even when the first locking part hooked by the first feed roll and the second locking part hooked by the second feed roll are provided on the feed frame, the same effect as described above can be obtained. In particular, when the first feed roll is locked at the first locking part and the second feed roll is locked at the second locking part, a more stable locking state can be obtained.

[0010] In one embodiment of the connector processing device of the present invention, the first locking part may include a first inner layer locking part and a first outer layer locking part, and the second locking part may include a second inner layer locking part and a second outer layer locking part. The first wire-hanging action when unwinding the yarn from the outer layer of the first yarn feed roll involves holding the yarn end on the inner layer of the first yarn feed roll by a suction holding part, and moving the suction holding part by a moving part to lock the yarn of the first yarn feed roll in place with the first inner layer locking part. The second wire-hanging action when unwinding the yarn from the outer layer of the first yarn feed roll involves holding the yarn end on the outer layer of the second yarn feed roll by a suction holding part, and moving the suction holding part by a moving part to lock the yarn of the first yarn feed roll in place with the first inner layer locking part. The first setting action when unwinding the yarn from the outer layer of the first yarn feed roll involves moving the holding part to lock the yarn of the second feed roll onto the second outer layer side using the locking part. This action involves holding the yarn end of the inner layer side of the first yarn feed roll with the suction holding part, and moving the suction holding part with the moving part to position the yarn end of the inner layer side of the first yarn feed roll onto the connecting part. The second setting action when unwinding the yarn from the outer layer side of the first yarn feed roll involves holding the yarn end of the outer layer side of the second yarn feed roll with the suction holding part, and moving the suction holding part with the moving part to position the yarn end of the outer layer side of the second yarn feed roll onto the connecting part. The connecting action is the action of connecting the inner layer end of the first yarn feed roll to the outer layer end of the second yarn feed roll. The first yarn-hanging action when unwinding the yarn from the outer layer of the second yarn feed roll involves holding the outer layer end of the first yarn feed roll with the suction and holding part, and moving the suction and holding part to lock the yarn of the first yarn feed roll against the first outer layer locking part. The second yarn-hanging action when unwinding the yarn from the outer layer of the second yarn feed roll involves holding the inner layer end of the second yarn feed roll with the suction and holding part, and moving the suction and holding part to lock the yarn of the second yarn feed roll against the second inner layer locking part. The first setting action when unwinding the yarn from the outer layer side is to hold the yarn end of the outer layer side of the first yarn feed roll by the suction and holding part, and to move the suction and holding part by the moving part so that the yarn end of the outer layer side of the first yarn feed roll is set at the connecting part. The second setting action when unwinding the yarn from the outer layer side of the second yarn feed roll is to hold the yarn end of the inner layer side of the second yarn feed roll by the suction and holding part, and to move the suction and holding part by the moving part so that the yarn end of the inner layer side of the second yarn feed roll is set at the connecting part. The connection action when unwinding the yarn from the outer layer side of the second yarn feed roll is to connect the yarn end of the outer layer side of the first yarn feed roll with the yarn end of the inner layer side of the second yarn feed roll.

[0011] In this splice processing device, even when locking portions are provided in the wire feeder corresponding to the inner layer of the first wire feed roll, the outer layer of the first wire feed roll, the inner layer of the second wire feed roll, and the outer layer of the second wire feed roll, respectively, the same effect as described above can be obtained. In particular, when unwinding the wire from the outer layer of the first wire feed roll, if the wire of the first wire feed roll is locked to the first inner layer locking portion and the wire of the second wire feed roll is locked to the second outer layer locking portion, and when unwinding the wire from the outer layer of the second wire feed roll, if the wire of the first wire feed roll is locked to the first outer layer locking portion and the wire of the second wire feed roll is locked to the second inner layer locking portion, the stability of the locking state in each locking portion can be further improved.

[0012] One aspect of the present invention relates to a yarn feeding device comprising: a yarn feeding frame having a first mounting portion for mounting a first yarn feeding roll, a second mounting portion for mounting a second yarn feeding roll, and a locking portion for locking the yarn; and a splicing device for connecting the yarn end of the first yarn feeding roll mounted on the first mounting portion to the yarn end of the second yarn feeding roll mounted on the second mounting portion, and making the connected yarn locked in the locking portion. In this yarn feeding device, the locking portion includes: at least one first locking portion for locking the yarn pulled out from the first yarn feeding roll; and at least one second locking portion for locking the yarn pulled out from the second yarn feeding roll. The splicing device comprises: a suction holding portion for holding the yarn by attracting the yarn; a moving portion for moving the suction holding portion; a connecting portion for connecting the yarn end of the first yarn feeding roll to the yarn end of the second yarn feeding roll; and a control portion for controlling the connecting portion, the suction holding portion, and the moving portion. The control portion controls the suction holding portion, the moving portion, and the connecting portion to perform splicing processing, which includes: a first... The first setting action involves holding the end of the first feed yarn package by the suction holding part, and moving the suction holding part by the moving part to set the end of the first feed yarn package at the connecting part; the second setting action involves holding the end of the second feed yarn package by the suction holding part, and moving the suction holding part by the moving part to set the end of the second feed yarn package at the connecting part; and the connecting action involves connecting the end of the first feed yarn package to the end of the second feed yarn package by the connecting part after the first setting action and the second setting action, and controlling the suction holding part and the moving part to perform a yarn hanging process, which includes at least one of the following actions: a first yarn hanging action, in which, before the first setting action, the end of the first feed yarn package is held by the suction holding part, and the suction holding part is moved by the moving part to stop the yarn of the first feed yarn package at the locking part; and a second yarn hanging action, in which, before the second setting action, the end of the second feed yarn package is held by the suction holding part, and the suction holding part is moved by the moving part to stop the yarn of the second feed yarn package at the locking part.

[0013] In this wire feeding device, unlike the conventional operation sequence performed by the operator, the wire is hooked onto the locking part before connection. Then, the wires of both the first and second wire feeding rolls, held by the suction holding part, are always subject to attraction in the suction direction, thus applying tension to the portion of the wire extending from the wire feeding rolls to the suction holding part. The moving part allows the tensioned wire end to move, enabling more precise wire movement compared to moving the irregularly slack wire end, thus allowing for high-precision hooking onto the locking part. Furthermore, since the wire is held by suction, the wire damage that occurs when gripping is not performed. Moreover, when the wire ends of the first and second wire feeding rolls are connected by suction holding, the wire can be damaged because it is attracted by the suction holding part while a portion of the wire is bent; however, in this configuration, the wire ends of both the first and second wire feeding rolls are attracted, thus preventing such bending. Therefore, even if the thread is held by the suction holding part, the thread will not be damaged.

[0014] Furthermore, in this yarn feeding device, the yarn feeding frame is provided with a first locking part corresponding to the first yarn feeding roll and a second locking part corresponding to the second yarn feeding roll. Therefore, compared to locking parts that are used for both the first and second yarn feeding rolls, the first and second locking parts can be positioned and oriented in a more suitable manner. As a result, yarn feeding can be easily performed, and the fed yarn is less likely to detach.

[0015] Furthermore, in this wire feeding device, the load exerted on the locking portion when the wire feed roll is rotated to remove slack after the splicing operation can be distributed to each of the first locking portion and the second locking portion. Therefore, it is possible to more effectively prevent the wire from detaching from each of the first and second locking portions. Moreover, even if the wire detaches from one of the first or second locking portions, since the wire is locked to the other of the first and second locking portions, the locked state of the wires connected between the wire feed rolls can be maintained.

[0016] As explained above, the wire feeding device with this configuration can achieve both the maintenance of wire quality and the improvement of operating accuracy, and can automate a series of actions including splicing and wire hanging.

[0017] In one embodiment of the wire feeding device of the present invention, the first locking part may be disposed at a position closer to the first mounting part than the center between the first mounting part and the second mounting part, and the second locking part may be disposed at a position closer to the second mounting part than the center between the first mounting part and the second mounting part.

[0018] In this configuration, the yarn pulled from the first yarn feed roll is secured to a first locking part located near the first yarn feed roll, and the yarn pulled from the second yarn feed roll is secured to a second locking part located near the second yarn feed roll. This allows for more stable and precise yarn loading at both the first and second locking parts.

[0019] In one embodiment of the present invention, the yarn feeding device may also include a first locking portion comprising a first inner layer locking portion and a first outer layer locking portion, and a second locking portion comprising a second inner layer locking portion and a second outer layer locking portion. The first yarn-hanging action when unwinding the yarn from the outer layer of the first yarn feeding roll involves holding the yarn end on the inner layer of the first yarn feeding roll by a suction and holding portion, and moving the suction and holding portion by a moving portion to lock the yarn of the first yarn feeding roll at the first inner layer locking portion. The second yarn-hanging action when unwinding the yarn from the outer layer of the first yarn feeding roll involves holding the yarn end on the outer layer of the second yarn feeding roll by a suction and holding portion, and moving the suction and holding portion by a moving portion to lock the yarn at the first inner layer locking portion. The first setting action when unwinding the yarn from the outer layer of the first yarn feed roll involves moving the holding part to lock the yarn of the second feed roll onto the second outer layer side using the locking part. This action involves holding the yarn end of the inner layer side of the first yarn feed roll with the suction holding part, and moving the suction holding part with the moving part to set the yarn end of the inner layer side of the first yarn feed roll onto the connecting part. The second setting action when unwinding the yarn from the outer layer side of the first yarn feed roll involves holding the yarn end of the outer layer side of the second yarn feed roll with the suction holding part, and moving the suction holding part with the moving part to set the yarn end of the outer layer side of the second yarn feed roll onto the connecting part. This action is repeated during the unwinding process from the outer layer side of the first yarn feed roll. The first winding action connects the inner layer of the first yarn feed roll to the outer layer of the second yarn feed roll. The first winding action when unwinding the yarn from the outer layer of the second yarn feed roll involves holding the outer layer of the first yarn feed roll with a suction and holding part, and moving the suction and holding part to lock the yarn in place with the first outer layer locking part. The second winding action when unwinding the yarn from the outer layer of the second yarn feed roll involves holding the inner layer of the second yarn feed roll with a suction and holding part, and moving the suction and holding part to lock the yarn in place with the second inner layer locking part. The first setting action when unwinding the yarn from the outer layer is to hold the yarn end of the outer layer of the first yarn feed roll by the suction and holding part, and to move the suction and holding part by the moving part so that the yarn end of the outer layer of the first yarn feed roll is set at the connecting part. The second setting action when unwinding the yarn from the outer layer of the second yarn feed roll is to hold the yarn end of the inner layer of the second yarn feed roll by the suction and holding part, and to move the suction and holding part by the moving part so that the yarn end of the inner layer of the second yarn feed roll is set at the connecting part. The connection action when unwinding the yarn from the outer layer of the second yarn feed roll is to connect the yarn end of the outer layer of the first yarn feed roll with the yarn end of the inner layer of the second yarn feed roll.

[0020] In the wire feeding frame of this wire feeding device, locking portions are respectively provided corresponding to the wires on the inner layer side of the first wire feeding roll, the wires on the outer layer side of the first wire feeding roll, the wires on the inner layer side of the second wire feeding roll, and the wires on the outer layer side of the second wire feeding roll. This allows each locking portion to be positioned and oriented in a more appropriate manner. As a result, the accuracy and stability of wire feeding at each locking portion can be further improved.

[0021] According to one aspect of the present invention, it is possible to maintain the quality of the yarn and improve the precision of the operation, and at the same time, it is possible to automate a series of actions including splicing and yarn hanging. Attached Figure Description

Detailed Implementation

[0052] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Furthermore, in the description of the drawings, the same or equivalent elements are given the same reference numerals, and repeated descriptions are omitted.

[0053] like Figure 1 As shown, one embodiment of the yarn feeding device 100 includes a bobbin holder (yarn feeder) 20 and a splicing device 9A. The bobbin holder 20 is installed on the false twisting machine 1. One embodiment of the splicing device 9A is mounted on the winding changer 9. The splicing device 9A is configured including the splicing device 60 described in detail later and a control unit 94 (see reference). Figure 1 as well as Figure 11 In the following explanation, the “Z direction” shown in the figure is the vertical direction (up and down direction), the “X direction” is the horizontal direction, and the “Y direction” is the horizontal direction orthogonal to the “X direction”, and is also orthogonal to both the X and Z directions.

[0054] Figure 1The false-twist processing machine 1 shown processes filaments (synthetic fiber filaments) Y supplied from multiple feed packages P1 to produce a take-up package P2. The filament Y is, for example, a synthetic fiber filament composed of thermoplastic synthetic fibers such as polyester or polyamide. Partially oriented yarn (POY) is wound onto a feed spool B1 to form the feed package P1. Draw textured yarn (DTY) is wound onto a take-up spool B2 to form the take-up package P2. In other words, the false-twist processing machine 1 processes the partially oriented filament Y to produce a draw textured yarn.

[0055] like Figure 2 As shown, a connector 8 is mounted on the feed roll P1. The connector 8 holds the yarn Y. The connector 8 has a mounting portion 81, a first holding portion 82, and a second holding portion 83. The mounting portion 81 is mounted to the feed bobbin B1 of the feed roll P1 in a manner that allows for synchronous rotation. The mounting portion 81 is formed in a cylindrical shape. The mounting portion 81 is mounted on the end of the feed bobbin B1 that protrudes from the side of the feed roll P1.

[0056] The first holding part 82 holds the end of the filament Y on the outer layer side (filament head side) of the filament package P1 (hereinafter, the end of the filament Y on the outer layer side is also referred to as the first filament end Y1). The first holding part 82 is provided on the mounting part 81. The first holding part 82 has a first arm 821, a first gripper 822, and a first guide 823. The base end side of the first arm 821 is fixed to the side of the mounting part 81 and extends radially along the mounting part 81. The first gripper 822 holds the first filament end Y1. The first gripper 822 is provided on the front end side of the first arm 821. The first guide 823 is provided on the first arm 821.

[0057] The second holding part 83 holds the end of the filament Y on the inner layer side (the tail side) of the filament package P1 (hereinafter, the end of the filament Y on the inner layer side is also referred to as the second filament end Y2). The second holding part 83 is provided on the mounting part 81. The second holding part 83 has a second arm 831, a second gripper 832, and a second guide 833. The base end side of the second arm 831 is fixed to the side of the mounting part 81 and extends radially along the mounting part 81. The second arm 831 is configured to be in a position that is in the same straight line as the first arm 821. The second gripper 832 holds the second filament end Y2. The second gripper 832 is provided on the front end side of the second arm 831. The second guide 833 is provided on the second arm 831. In addition, the first filament end Y1 and the second filament end Y2 mentioned here refer not only to the front end of the filament Y, but also to the portion of the filament with a predetermined length based on the front end.

[0058] In the connector 8, the first end Y1 of the feed roll P1 is held by the first guide 822 via the first retainer 823 of the first holding part 82, and the second end Y2 pulled out from the inner layer side of the feed roll P1 is held by the second retainer 832 via the first guide 823 of the first holding part 82 and the second guide 833 of the second holding part 83. The connector 8 is installed on the feed roll P1 by the operator, for example. A bobbin cover (not shown) may also be installed on the end opposite to the end on which the connector 8 is installed on the feed bobbin B1.

[0059] like Figure 1 As shown, the false twisting processing machine 1 includes a yarn feeding section 2, a processing section 3, a winding section 4, a main body 5, a winding table 6, and a support frame 7. The various components of the yarn feeding section 2, processing section 3, and winding section 4 described later are aligned with the travel surface of the yarn Y disposed on the yarn channel from the yarn feeding section 2 through the processing section 3 to the winding section 4. Figure 1 There are multiple [items] arranged orthogonally in the Y direction (the longitudinal direction of the body) on the paper.

[0060] The wire feeding unit 2 supplies wire Y to the processing unit 3. The wire feeding unit 2 includes a bobbin holder 20 that holds multiple wire feed rolls P1. Figure 1 as well as Figure 3 As shown, the bobbin frame 20 includes a bobbin base 21, a first support column 22, a second support column 23, a partition plate 24, a bobbin (first mounting part and second mounting part) 25, and a clamp (locking part) 29. The bobbin base 21 is provided on the ground or the like and supports the first support column 22 and the second support column 23. The first support column 22 and the second support column 23 are erected on the bobbin base 21.

[0061] The first support column 22 extends along the Z direction (vertical direction). The first support columns 22 are arranged at equal intervals in the Y direction. The first support columns 22 are disposed on one side F1 of the bobbin holder 20 in the X direction. The side F1 in the X direction is the side where the processing unit 3, which will be described in detail later, is disposed, and is the side where the yarn Y is fed to the processing unit 3 for performing false twisting.

[0062] The second support column 23 extends along the Z direction. The second support columns 23 are arranged in pairs along the Y direction, with multiple sets of second support columns 23 arranged in the Y direction. The second support columns 23 are located on the opposite side F2 of the roll rack 20 in the X direction. The opposite side F2 in the X direction is the side through which the winding changer 9, described in detail later, travels, and is the side where the operator performs the splicing operation. The first support column group 22, consisting of multiple first support columns 22, and the second support column group 23, consisting of multiple second support columns 23, are arranged opposite each other in the X direction.

[0063] The divider 24 is arranged across the first post 22 and the second post 23. The divider 24 is a plate-shaped component, arranged at predetermined intervals in the Z direction. The divider 24 prevents the yarn feed package P1 from falling off the bobbin 25.

[0064] The bobbin 25 supports the yarn feed roll P1. The bobbin 25 is disposed on the second post 23. Multiple bobbins 25 are arranged at predetermined intervals (e.g., 4) in the Z direction of the second post 23. The bobbins 25 are arranged between two partition plates 24 in the Z direction. In addition, multiple sets (pairs) of bobbins 25 are arranged in pairs in the Y direction, corresponding to the second posts 23, 23 arranged in pairs.

[0065] In this bobbin configuration 25, the yarn Y of the feed roll P1 supported by one bobbin (first bobbin) 25 can be connected to the yarn Y of the feed roll P1 supported by the other bobbin (second bobbin) 25. Specifically, the first yarn end Y1 of the feed roll P1 supported by one bobbin 25 is connected to the second yarn end Y2 of the feed roll P1 supported by the other bobbin 25, or the second yarn end Y2 of the feed roll P1 supported by one bobbin 25 is connected to the first yarn end Y1 of the feed roll P1 supported by the other bobbin 25. Thus, one yarn Y is supplied from the two feed rolls P1, P1 supported by the pair of bobbins 25, 25 respectively. That is, yarn Y can be continuously supplied to the processing unit 3.

[0066] The clamp 29 is disposed in the Y direction between the pair of bobbins 25, 25. In this embodiment, it is disposed at the center of the pair of bobbins 25, 25. Figure 4 As shown, the clamp 29 has a pair of disc-shaped plates 291, 292, an elastic member 293 that applies force to the pair of disc-shaped plates 291, 292 toward the partition plate 24, and a shaft portion 294. The pair of disc-shaped plates 291, 292 are configured to move within a predetermined range in the extending direction of the shaft portion 294, and are applied force to the partition plate 24 by the elastic member 293. The wire Y is configured such that when disposed between the pair of disc-shaped plates 291, 292, it is clamped by the pair of disc-shaped plates 291, 292, and the wire Y is locked. Furthermore, the elastic force of the elastic member 293 is appropriately selected or adjusted so that it disengages from the locking of the pair of disc-shaped plates 291, 292 when the operator pulls the wire Y.

[0067] like Figure 5 As shown, the bobbin 25 has a yarn feeding and winding support 251, a bobbin body 252, a first rotating mechanism 253, a body support 254, and a second rotating mechanism 255.

[0068] The yarn feed roll support 251 supports the yarn feed roll P1. The yarn feed roll support 251 includes roll support members 251A and 251B. The roll support members 251A and 251B are rod-shaped members. The roll support members 251A and 251B are rotatably supported by the bobbin body 252. The roll support members 251A and 251B are arranged at predetermined intervals, extending in one direction and parallel to each other. The bobbin 25 supports the yarn feed roll P1 at two points via the roll support members 251A and 251B.

[0069] A cover portion 251D is provided at one end of the winding support member 251A in the extending direction. A cover portion 251E is provided at one end of the winding support member 251B in the extending direction. The cover portions 251D and 251E are formed, for example, of rubber (resin) with a high coefficient of friction. The cover portions 251D and 251E are in contact (abut against) with the inner circumferential surface of the feed bobbin B1 that winds up the winding P2. One end of the winding support member 251A and one end of the winding support member 251B are connected by a connecting member 251F.

[0070] The bobbin body 252 supports the winding support members 251A and 251B so that they can rotate about their rotation axis. The bobbin body 252 is provided with a limiting member 252A. The limiting member 252A is, for example, formed in a disc shape. The limiting member 252A is disposed on one side of the bobbin body 252. The limiting member 252A is inserted into and installed by the winding support members 251A and 251B. The limiting member 252A faces the end face of the feed yarn package P1 and limits the movement of the feed yarn package P1 in the extending direction of the winding support members 251A and 251B. An insertion hole 252B is formed in the bobbin body 252. The second support post 23 of the bobbin holder 20 (see reference) Figure 3 Insert into insertion hole 252B.

[0071] The first rotating mechanism 253 includes a driven pulley 253A, a drive pulley 253B, a power transmission belt 253C, and a first wheel 253D. The driven pulley 253A is disposed at the other end of the coil support member 251A. The drive pulley 253B is disposed at the other end of the coil support member 251B. The power transmission belt 253C is mounted on the driven pulley 253A and the drive pulley 253B. The first wheel 253D is disposed on the drive pulley 253B (coil support member 251B). In this embodiment, the first wheel 253D is a cross wheel constituting a cross wheel mechanism. The first wheel 253D is rotated by the rotational drive of the first joint driver 621 or the second joint driver 631 of the joint device 60 described later.

[0072] The main support portion 254 is cylindrical. One end of the main support portion 254 is connected to the bobbin body portion 252, and the main support portion 254 and the bobbin body portion 252 are integrally formed. The hollow portion of the main support portion 254 communicates with the insertion hole 252B of the bobbin body portion 252. A second support column 23 of the bobbin holder 20 (see reference) is inserted into the main support portion 254. Figure 3 ).

[0073] The second rotating mechanism 255 is a cross wheel constituting the cross wheel mechanism. The second rotating mechanism 255 is connected to the other end of the main support portion 254, and is integrally formed with the main support portion 254. The second rotating mechanism 255 rotates under the drive of the rotating drive 932A of the rotating device 932 (described later). The bobbin body portion 252 rotates along with the rotation of the second rotating mechanism 255. As a result, the winding support members 251A and 251B rotate.

[0074] Processing unit 3 performs false twisting on the yarn Y supplied from yarn feeding unit 2. For example... Figure 1 As shown, the processing unit 3 includes an anti-twist guide 31, a first heating device 32, a cooling device 33, a false twisting device 34, a second heating device 35, and feed rollers 36 (feed rollers 361 to 363). The anti-twist guide 31, the first heating device 32, the cooling device 33, the false twisting device 34, the second heating device 35, and the feed rollers 36 (feed rollers 361 to 363) are each independently provided with respect to each yarn Y supplied from the yarn supply unit 2, and are arranged in a row in the Y direction.

[0075] The anti-twist guide 31 prevents the twist direction applied to the yarn Y by the false twist device 34 (described later) from propagating to the upstream side of the yarn travel direction. The first heating device 32 heats the yarn Y fed from the yarn supply section 2 via the feed roller 361. The cooling device 33 cools the yarn Y heated by the first heating device 32. The false twist device 34 twists the yarn Y. The second heating device 35 heats the yarn Y fed from the false twist device 34 via the feed roller 362.

[0076] A feed roller 361 is provided between the bobbin holder 20 and the anti-twist guide 31; a feed roller 362 is provided between the false twist device 34 and the second heating device 35; and a feed roller 363 is provided between the second heating device 35 and the winding device 41. Each feed roller 36 (feed rollers 361 to 363) comprises a drive roller and a driven roller. Each feed roller 36 is also arranged in a row in the Y direction.

[0077] The feeding speed of the yarn Y by the feeding roller 362 is faster than that of the feeding roller 361, and the yarn Y is stretched between the feeding rollers 361 and 362. The feeding speed of the yarn Y by the feeding roller 363 is slower than that of the feeding roller 362, and the yarn Y is relaxed between the feeding rollers 362 and 363.

[0078] In the processing section 3 configured as described above, the yarn Y stretched between the feed rollers 361 and 362 is twisted by the false twisting device 34. The twist generated by the false twisting device 34 propagates to the anti-twist guide 31, but does not propagate upstream of the anti-twist guide 31 in the yarn travel direction. The yarn Y, which is stretched and twisted simultaneously, is heat-set by the first heating device 32 and then cooled by the cooling device 33. Downstream of the false twisting device 34, the yarn Y is untwisted, but each filament remains falsely twisted due to the aforementioned heat setting.

[0079] The yarn Y is relaxed between the feed rollers 362 and 363 and is heat-set by the second heating device 35. Finally, the yarn Y fed from the feed rollers 363 is wound by the winding device 41 of the winding section 4 to form a wound package P2.

[0080] The take-up unit 4 includes a take-up device 41, a package memory 42, and a doffing device (not shown). The take-up device 41 takes up the yarn Y, which has undergone false twisting processing by the processing unit 3, to form a take-up package P2. The package memory 42 stores the take-up package P2 formed by the take-up device 41. The doffing device removes the take-up package P2 formed by the take-up device 41, transfers the take-up package P2 to the package memory 42, and installs an empty take-up bobbin B2 into the take-up device 41.

[0081] The roll changing device 9 retrieves the feed spool B1 from the bobbin 25 and installs the feed roll P1 onto the bobbin 25. For example... Figure 6 As shown, the roll changing device 9 travels along the track 98. The track 98 is laid on the floor and extends along the Y direction. That is, the roll changing device 9 is configured to travel along the Y direction. The roll changing device 9 includes a traveling unit 90, a lifting unit 91, a holding unit 92, a changing unit 93, a connector device 60, and a control unit 94 (see reference) that controls the operation of each unit 90, 91, 92, 93 and the connector device 60. Figure 11 ).

[0082] The traveling unit 90 is equipped with wheels that travel on the track 98 and a drive mechanism. The traveling unit 90 supports the lifting unit 91, the holding unit 92, and the changing unit 93. The lifting unit 91 is used for lifting and lowering by a worker. The lifting unit 91 is used for maintenance and other purposes. The lifting unit 91 includes a work platform 911 for the worker to sit on, a guide section 912 supporting the work platform 911 so that it can move in the Z direction, and a drive mechanism (not shown) for driving the work platform.

[0083] The holding unit 92 holds multiple (e.g., four) feed rolls P1. The holding unit 92 temporarily holds the feed rolls P1 upon receiving a supply of feed rolls P1 from the roll replenishment device (not shown) and supplies feed rolls P1 to the changing unit 93. The holding unit 92 is configured to rotate within approximately 90°. More specifically, the holding unit 92 is configured to be able to rotate between the replenishment position where it receives a supply of feed rolls P1 from the roll replenishment device and the supply position where it supplies feed rolls P1 to the changing unit 93. Figure 6 Rotate between the positions shown.

[0084] The replacement unit 93 replaces the feed spool B1 and the feed roll P1 on the bobbin 25. Specifically, the replacement unit 93 retrieves the feed spool B1 from the bobbin 25 (see reference). Figure 1 ), and install the yarn feed roll P1 onto the bobbin 25. Replacement unit 93 and holding unit 92 are connected in adjacent grounding configuration. For example... Figure 7 As shown, the replacement unit 93 includes a base 931, a rotating device 932, a recovery device 933, a supply device 934, and a rotary table 936. Furthermore, in Figure 6 The description of the rotating device 932, the recovery device 933, the supply device 934, the rotating table 936, and the joint device 60, which will be described in detail later, is omitted.

[0085] The base 931 supports the rotating device 932 and the rotating table 936. The rotating table 936 supports the recovery device 933, the supply device 934, and the connector device 60. The base 931 is configured to move freely up and down along the Z direction. The rotating device 932 is fixed to the base 931. The rotating device 932 rotates the bobbin 25 of the bobbin holder 20. The rotating device 932 has a rotating drive 932A and a rotating arm 932B.

[0086] Rotary driver 932A causes the second rotating mechanism 255 of bobbin 25 (see reference) to rotate. Figure 5Rotation. The rotary actuator 932A is a cross wheel actuator constituting the cross wheel mechanism. The rotary actuator 932A is rotated by the rotation drive of a motor (not shown). The rotary arm 932B supports the rotary actuator 932A. The rotary arm 932B is configured to swing in the horizontal direction. The rotary arm 932B is driven, for example, by a motor or a cylinder (not shown). The rotating device 932 is configured to correspond to one bobbin 25 and the other bobbin 25 arranged in pairs in the bobbin holder 20, respectively.

[0087] The rotating device 932 rotates the bobbin 25 to change its orientation when the yarn feed package P1 is installed onto the bobbin 25. More specifically, the rotating device 932 causes the rotating arm 932B to swing, thereby engaging the rotating driver 932A with the second rotating mechanism 255 of the bobbin 25. When the rotating driver 932A is engaged with the second rotating mechanism 255, the rotating device 932 rotates the rotating driver 932A in one direction. When the second rotating mechanism 255 rotates, the main body support 254 of the bobbin 25 rotates. As a result, the bobbin 25 rotates, and the front end of the yarn feed package support 251 faces the changing unit 93.

[0088] A recovery device 933 is mounted on a rotatable turntable 936 supported by a base 931. The recovery device 933 recovers the feed spool B1 from the bobbin 25. The recovery device 933 has a feed spool support 933A that supports the feed spool B1. The recovery device 933 recovers the feed spool B1 from the bobbin 25 by advancing the feed spool support 933A relative to the bobbin 25 when the feed spool B1 is not supported, and by retracting the feed spool support 933A relative to the bobbin 25 when the feed spool B1 is supported.

[0089] A feeding device 934 is provided on a rotatable turntable 936 supported by a base 931. The feeding device 934 supplies a feed roll P1 to the bobbin 25. The feeding device 934 has a feed roll feeding section 934A that supports the feed roll P1. The feeding device 934 supplies the feed roll P1 to the bobbin 25 by advancing the feed roll feeding section 934A relative to the bobbin 25 while supporting the feed roll P1, and by retracting the feed roll feeding section 934A relative to the bobbin 25 while not supporting the feed roll P1.

[0090] In addition to retrieving the feed bobbin B1 from the bobbin 25 and installing the feed roll P1 onto the bobbin 25 as described above, the roll changing device 9 also connects the ends of the pair of feed rolls P1, P1 installed on the pair of bobbins 25, 25 of the bobbin holder 20 to each other (joint processing), and secures the connected yarn to at least one clamp 29 provided on the bobbin holder 20 (thread hanging processing). The joint processing and thread hanging processing are performed by the joint processing device 9A. The joint processing device 9A consists of a joint device 60 and a control unit 94.

[0091] A splicing device 60 is provided on a rotatable rotary table 936 supported by a base 931. The splicing device 60 splices either the first yarn end Y1 of a yarn feed roll P1 supported by one bobbin 25 to the second yarn end Y2 of a yarn feed roll P1 supported by the other bobbin 25, or the second yarn end Y2 of a yarn feed roll P1 supported by one bobbin 25 to the first yarn end Y1 of a yarn feed roll P1 supported by the other bobbin 25. Hereinafter, the yarn feed roll P1 supported by one bobbin 25 will be referred to as the first yarn feed roll P11, and the yarn feed roll P1 supported by the other bobbin 25 will be referred to as the second yarn feed roll P12. Figure 8 , Figure 9 as well as Figure 10 As shown, the connector device 60 includes a wire hanging mechanism 61, a first rotating mechanism 62, a second rotating mechanism 63, and a connector mechanism 64.

[0092] The wire-hanging mechanism 61 captures the wire Y of the wire feed roll P1 and guides the wire Y to the splicing mechanism 64. The wire-hanging mechanism 61 captures the first wire end Y1 of the first wire feed roll P11 and the second wire end Y2 of the second wire feed roll P12 and guides them to the splicing mechanism 64, or captures the second wire end Y2 of the first wire feed roll P11 and the first wire end Y1 of the second wire feed roll P12 and guides them to the splicing mechanism 64. The wire-hanging mechanism 61 includes a suction gun 611, an arm (moving part) 612, and a hook 615.

[0093] The suction gun 611 attracts and captures the thread Y. The suction gun 611 has a suction tube 613 and a suction nozzle (suction holding part) 614. The suction nozzle 614 is located at the front end of the suction tube 613. The suction nozzle 614 attracts the thread Y. The suction tube 613 is connected to a negative pressure source (not shown). This generates a suction flow at the suction nozzle 614. One side of the base of the suction tube 613 is connected to an arm 612. A hook 615 is located at the front end of the suction tube 613, facing away from the suction nozzle 614. The hook 615 engages and moves the thread Y after it has been joined (joined) by the connector device 60. The arm 612 moves the suction gun 611. The arm 612 includes a linkage mechanism and multiple motors. The arm 612 is supported by a bracket 616.

[0094] The first rotating mechanism 62 operates on one bobbin 25 to rotate the first yarn feed roll P11. The first rotating mechanism 62 rotates the first yarn feed roll P11 to discharge yarn Y from the first yarn feed roll P11 when the yarn Y is guided to the splicing mechanism 64 by the yarn hanging mechanism 61. The second rotating mechanism 63 operates on the other bobbin 25 to rotate the second yarn feed roll P12. The second rotating mechanism 63 rotates the second yarn feed roll P12 to discharge yarn Y from the second yarn feed roll P12 when the yarn Y is guided to the splicing mechanism 64 by the yarn hanging mechanism 61.

[0095] The first rotating mechanism 62 includes a first connector driver 621, a first motor 622, and a first arm 623. The first connector driver 621 is rotatably supported by the first arm 623. A first driven pulley 624 is provided on the first connector driver 621. The first motor 622 is fixed to the first arm 623. A first drive pulley 625 is connected to the output shaft of the first motor 622. The first motor 622 drives the first drive pulley 625 to rotate around its axis. A first power transmission belt 626 is mounted on the first driven pulley 624 and the first drive pulley 625. Thus, the first connector driver 621 rotates due to the rotational drive of the first motor 622.

[0096] The second rotating mechanism 63 includes a second connector driver 631, a second motor 632, and a second arm 633. The second connector driver 631 is rotatably supported by the second arm 633. A second driven pulley 634 is provided on the second connector driver 631. The second motor 632 is fixed to the second arm 633. A second drive pulley 635 is connected to the output shaft of the second motor 632. The second motor 632 drives the second drive pulley 635 to rotate around its axis. A second power transmission belt 636 is mounted on the second driven pulley 634 and the second drive pulley 635. Thus, the second connector driver 631 rotates due to the rotational drive of the second motor 632.

[0097] The jointing mechanism 64 performs the jointing. The jointing mechanism (connecting part) 64 has a knotter 66, a first guide mechanism 67 and a second guide mechanism 68.

[0098] The twister 66 includes a connector 661, a pair of clamping portions 662 and 663, a cutter 664 disposed on the clamping portion 662, and a cutter 665 disposed on the clamping portion 663. The connector 661 interlocks (connects) the first filament Y1 of the first feed roll P11 with the second filament Y2 of the second feed roll P12, or interlocks (connects) the second filament Y2 of the first feed roll P11 with the first filament Y1 of the second feed roll P12. The pair of clamping portions 662 and 663 are positioned to clamp the connector 661. The pair of clamping portions 662 and 663 clamp the filament Y (first filament Y1 and second filament Y2; see reference) inserted into the cavity of the connector 661. Figure 14A Cutters 664 and 665 cut off excess portions, including those held by suction nozzle 614, from the joint portion of the thread Y after it has been joined by connector 661.

[0099] The first guiding mechanism 67 guides the yarn Y by locking it in place. The first guiding mechanism 67 is configured to be oscillating. A potentiometer (not shown) for detecting the tension of the yarn Y is provided in the first guiding mechanism 67. The connector device 60 controls the operation of the first motor 622 of the first rotating mechanism 62 based on the detection result of the potentiometer. That is, the connector device 60 adjusts the rotation amount (discharge amount) of the first yarn feed roll P11 based on the detection result of the potentiometer, and pulls the yarn Y out of the first yarn feed roll P11 with a specified tension.

[0100] The second guiding mechanism 68 guides the yarn Y by locking it in place. The second guiding mechanism 68 is configured to be oscillating. A potentiometer (not shown) for detecting the tension of the yarn Y is provided in the second guiding mechanism 68. The connector device 60 controls the operation of the second motor 632 of the second rotating mechanism 63 based on the potentiometer's detection result. That is, the connector device 60 adjusts the rotation amount (discharge amount) of the second yarn feed roll P12 based on the potentiometer's detection result, and pulls the yarn Y out of the second yarn feed roll P12 with a predetermined tension.

[0101] like Figure 7 As shown, the rotary table 936 is rotatably supported on the base 931. When the feed bobbin B1 is retracted, the rotary table 936 is rotated so that the feed bobbin support 933A is positioned on the front of the bobbin 25. Furthermore, when the feed package P1 is supplied, the rotary table 936 is rotated so that the feed package supply section 934A is positioned on the front of the bobbin 25. Additionally, the rotary table 936 is rotated to be positioned on the front of the bobbin 25 when the splicing device 60 performs the splicing process for the thread Y.

[0102] like Figure 11As shown, the control unit 94 is an electronic control unit composed of a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), I / O ports, and communication ports. The ROM stores programs for controlling the various parts of the traveling unit 90, the lifting unit 91, the holding unit 92, and the changing unit 93. Furthermore, the function of the control unit 94 is to load prescribed computer software into hardware such as the CPU and main memory, thereby executing it under the control of the CPU.

[0103] The control unit 94 controls the suction nozzle 614, arm 612, and twister 66 to perform a jointing process including a first setting action, a second setting action, and a jointing action (connection action). Furthermore, the control unit 94 controls the suction nozzle 614 and arm 612 to perform a thread-hanging process including one of a first thread-hanging action and a second thread-hanging action.

[0104] In this embodiment, the first setting operation, the second setting operation, the jointing operation, the first wire hanging operation, and the second wire hanging operation are described when unwinding the wire Y from the outer layer side of the second wire feeding roll P12 (when supplying the wire Y to the processing section 3 from the outer layer side of the second wire feeding roll P12) (hereinafter also referred to as the first scenario).

[0105] The first setting action in the first scenario is as follows: the first filament end Y1 of the first filament feed roll P11 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to place the first filament end Y1 of the first filament feed roll P11 onto the twister 66. The second setting action is as follows: the second filament end Y2 of the second filament feed roll P12 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to place the second filament end Y2 of the second filament feed roll P12 onto the twister 66. The connecting action is as follows: after the first and second setting actions, the first filament end Y1 of the first filament feed roll P11 is connected to the second filament end Y2 of the second filament feed roll P12 by the twister 66.

[0106] The first thread-hanging action in the first scenario is as follows: Before the first setting action, the first thread end Y1 of the first thread feed roll P11 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the thread Y of the first thread feed roll P11 in the clamp 29. The second thread-hanging action in the first scenario is as follows: Before the second setting action, the second thread end Y2 of the second thread feed roll P12 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the thread Y of the second thread feed roll P12 in the clamp 29. In the first scenario, only either the first thread-hanging action or the second thread-hanging action is performed.

[0107] Next, in this embodiment, the first setting operation, the second setting operation, the jointing operation, the first wire hanging operation, and the second wire hanging operation will be described when unwinding the wire Y from the outer layer side of the first wire feeding roll P11 (when supplying the wire Y to the processing section 3 from the outer layer side of the first wire feeding roll P11) (hereinafter also referred to as the second scenario).

[0108] The first setting action in the second scenario is as follows: the second filament end Y2 of the first filament feed roll P11 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to place the second filament end Y2 of the first filament feed roll P11 onto the twister 66. The second setting action is as follows: the first filament end Y1 of the second filament feed roll P12 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to place the first filament end Y1 of the second filament feed roll P12 onto the twister 66. The connecting action is as follows: after the first and second setting actions, the second filament end Y2 of the first filament feed roll P11 is connected to the first filament end Y1 of the second filament feed roll P12 by the twister 66.

[0109] The first thread-hanging action in the second scenario is as follows: Before the first setting action, the second thread end Y2 of the first thread feed roll P11 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the thread Y of the first thread feed roll P11 in the clamp 29. The second thread-hanging action in the second scenario is as follows: Before the second setting action, the first thread end Y1 of the second thread feed roll P12 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the thread Y of the second thread feed roll P12 in the clamp 29. In the second scenario, only either the first thread-hanging action or the second thread-hanging action is performed.

[0110] The following uses Figures 10-11 5. A detailed description of a series of actions in the splicing device 9A, including splicing and wire hanging, will be provided. Here, the following case will be used as an example: When unwinding the yarn Y from the outer layer of the second yarn feed roll P12 (in the first scenario described above), the splicing device 60 splices the first yarn end Y1 of the first yarn feed roll P11 supported by one bobbin 25 with the second yarn end Y2 of the second yarn feed roll P12 supported by the other bobbin 25.

[0111] The joint processing device 9A is designed to, when the joint operation begins, such as Figure 10As shown, the first rotating mechanism 62 operates on one bobbin 25, and the second rotating mechanism 63 operates on the other bobbin 25. The suction nozzle 614 rotates the connector 8 to a position capable of capturing the first yarn end Y1 of the first yarn feed package P11 and the second yarn end Y2 of the second yarn feed package P12. Figure 12 Step S1).

[0112] Specifically, the control unit 94 drives the first motor 622 to rotate the first connector driver 621, which engages with the first wheel 253D of one bobbin 25. When the first connector driver 621 rotates, the first yarn feed package P11 rotates, and the connector 8 rotates accordingly. The control unit 94 also drives the second motor 632 to rotate the second connector driver 631, which engages with the first wheel 253D of the other bobbin 25. When the second connector driver 631 rotates, the second yarn feed package P12 rotates, and the connector 8 rotates accordingly. Based on the detection result of a sensor (not shown) that detects a detection body (not shown) provided on the connector 8, the control unit 94 controls the first motor 622 and the second motor 632 to rotate the connector 8 to a predetermined position.

[0113] Control unit 94 activates suction gun 611. Figure 12 Step S2). Thus, the suction gun 611 becomes capable of attracting and holding the yarn Y at the suction nozzle 614. The control unit 94 controls the arm 612, causing the suction nozzle 614 to capture (hold) the first yarn end Y1 of the first yarn feed roll P11. Figure 12 Step S3). Next, the control unit 94 controls the arm 612, such as... Figure 13A As shown, the suction nozzle 614 is moved to the clamp 29, and the yarn Y hook of the first yarn feed roll P11 is hooked (locked) onto the clamp 29. Figure 12 Step S4: First wire hanging action). More specifically, the wire Y of the first wire feeding roll P11 is clamped and stopped by a pair of disc plates 291, 292 of the clamp 29.

[0114] Next, the control unit 94 controls the arm 612 while the yarn Y-hook of the first yarn feed roll P11 is hooked onto the clamp 29, such as... Figure 13BAs shown, the suction nozzle 614, holding the first yarn end Y1 of the first yarn feed roll P11, is moved to the first guide mechanism 67, hooking the yarn Y of the first yarn feed roll P11 onto the first guide mechanism 67. Based on the detection result of the potentiometer installed on the first guide mechanism 67, the control unit 94 adjusts the rotation amount (discharge amount) of the first yarn feed roll P11, pulling the yarn Y out of the first yarn feed roll P11 with a predetermined tension. Furthermore, while the yarn Y of the first yarn feed roll P11 is hooked onto the first guide mechanism 67, the control unit 94 controls the arm 612, causing the suction nozzle 614 to move to the connector mechanism 64, thereby setting (guiding) the first yarn end Y1 of the first yarn feed roll P11 onto the connector mechanism 64. Figure 12 Step S5: First setup action).

[0115] Next, the control unit 94 causes the suction nozzle 614 to capture (hold) the second filament end Y2 of the second filament feed roll P12. Figure 12 Step S6). Next, the control unit 94 controls the arm 612, such as... Figure 14A As shown, the suction nozzle 614, which holds the second yarn end Y2 of the second yarn feed roll P12, is moved to the connector mechanism 64, and the second yarn end Y2 of the second yarn feed roll P12 is positioned (guided) in the connector mechanism 64. Figure 12 Step S7: Second setting action).

[0116] Next, the control unit 94 controls the twister 66 of the joint device 60, such as... Figure 14B As shown, the first yarn end Y1 of the first yarn feed roll P11 and the second yarn end Y2 of the second yarn feed roll P12 are joined (connected). Furthermore, the control unit 94 controls the cutters 664 and 665 of the joining device 60 to cut off excess material from the joint portion between the first yarn end Y1 of the first yarn feed roll P11 and the second yarn end Y2 of the second yarn feed roll P12, including the portion held by the suction nozzle 614. Figure 12 Step S8: Connector action (connection action)).

[0117] Next, the control unit 94 stops the suction gun 611. Figure 12 Step S9). Next, the control unit 94 controls the arm 612, and after hooking (holding) the thread after the joint to the hook 615, moves the hook 615 to the outside of the joint mechanism 64. Thus, as Figure 15A As shown, the thread Y after the connector disengages from the locking mechanisms 64, 67, and 68, and extends to the outside of the connector device 60. Figure 12 Step S10).

[0118] Next, the control unit 94 controls the first motor 622 and the second motor 632 to drive the first connector driver 621 and the second connector driver 631 to rotate, as follows: Figure 15B As shown, the first feed roll P11 and the second feed roll P12 are rotated. This eliminates slack in the yarn Y after the connector when it is hooked onto the clamp 29. Figure 12 Step S11).

[0119] In the splice processing apparatus 9A of the above embodiment, unlike the conventional operation sequence performed by the operator, the yarn Y is pre-loaded onto the clamp 29 before splicing the yarn Y. Then, the yarns Y, Y of the first yarn feed roll P11 and the second yarn feed roll P12, held by the suction nozzle 614, are always attracted in the suction direction, thus applying tension to the portion of yarn Y from the first yarn feed roll P11 and the second yarn feed roll P12 up to the suction nozzle 614. The arm 612 can move the tensioned first yarn end Y1 (or second yarn end Y2), thus allowing for more precise movement of the yarn Y compared to moving the irregularly slack first yarn end Y1 (or second yarn end Y2), enabling high-precision pre-loading onto the clamp 29.

[0120] Furthermore, since the thread Y is held by suction from the nozzle 614, no damage to the thread Y occurs when it is being held. Additionally, when suction is applied to a thread Y in which the first end Y1 of the first feed roll P11 is connected to the second end Y2 of the second feed roll P12, or vice versa, a portion of the thread Y is drawn in a bent state by the nozzle 614, which could damage the thread Y. However, in the configuration described above, the thread Y is held by suction from either the first end Y1 or the second end Y2 of the first feed roll P11, or the second end Y2 or the first end Y1 of the second feed roll P12, thus preventing such bending. Therefore, even when the thread Y of the first feed roll P11 and the second feed roll P12 is held by the nozzle 614, the thread Y will not be damaged. As a result, it is possible to maintain the quality of the yarn while improving the precision of the operation, and to automate a series of actions including splicing and yarn hanging.

[0121] The above describes one embodiment of the present invention, but the present invention is not limited to the above embodiment, and various modifications can be made without departing from its spirit.

[0122] (Variation Example 1)

[0123] In the cylinder frame 20 of the above embodiment, regarding the clamp 29, as... Figure 3 As shown, an example of one bobbin 25, 25 positioned between the aforementioned pair of bobbins in the Y direction has been given for illustration, but this is not a limitation. For example, it is also possible to... Figure 16 As shown, the bobbin 20 has two grippers 29A and 29B arranged in the Y direction between a pair of bobbins 25, 25.

[0124] That is, in the bobbin holder 20 according to Modification 1, it is configured to include a first clamp (locking part, first locking part) 29A disposed at a position where the first feed roll P11 supported by one bobbin 25 is away from the second feed roll P12 supported by the other bobbin 25, and a second clamp (locking part, second locking part) 29B disposed at a position where the first feed roll P11 supported by one bobbin 25 is close to the second feed roll P12 supported by the other bobbin 25. In Modification 1, the first clamp 29A of the bobbin holder 20 is disposed at a position in the center between the pair of bobbins 25, 25 near the bobbin 25 of the one supporting the first feed roll P11, and the second clamp 29B is disposed at a position in the center between the pair of bobbins 25, 25 near the bobbin 25 of the other supporting the second feed roll P12.

[0125] In Modification 1, the control unit 94 of the splice processing apparatus 9A controls the suction nozzle 614, the arm 612, and the twister 66 to perform splice processing including a first setting action, a second setting action, and a splicing action (connection action). The first setting action, the second setting action, and the splicing action in the first scenario (when unwinding the yarn Y from the outer layer side of the second yarn feed roll P12) and the second scenario (when unwinding the yarn Y from the outer layer side of the first yarn feed roll P11) are the same as in the above embodiment, therefore detailed descriptions are omitted. In Modification 1, unlike the above embodiment, the control unit 94 controls the suction nozzle 614 and the arm 612 in each of the first and second scenarios to perform yarn-hanging processing including both a first yarn-hanging action and a second yarn-hanging action.

[0126] The first thread-hanging action in the first scenario is as follows: Before the first setting action, the first thread end Y1 of the first thread feed roll P11 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the thread Y of the first thread feed roll P11 at the first clamp 29A. The second thread-hanging action in the first scenario is as follows: Before the second setting action, the second thread end Y2 of the second thread feed roll P12 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the thread Y of the second thread feed roll P12 at the second clamp 29B.

[0127] The first thread-hanging action in the second scenario is as follows: Before the first setting action, the second thread end Y2 of the first thread feed roll P11 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the thread Y of the first thread feed roll P11 at the first clamp 29A. The second thread-hanging action in the second scenario is as follows: Before the second setting action, the first thread end Y1 of the second thread feed roll P12 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the thread Y of the second thread feed roll P12 at the second clamp 29B.

[0128] Furthermore, even in a configuration that includes a first clamp 29A and a second clamp 29B, in each of the first and second scenarios, only one of the first wire-hanging action and the second wire-hanging action may be performed.

[0129] The following uses Figures 17-18 9. A series of actions, including splicing and wire hanging, in the splicing device 9A will be described in detail. Here, the following case will be used as an example: When unwinding the yarn Y from the outer layer of the second yarn feed roll P12 (in the first scenario described above), the splicing device 60 splices the first yarn end Y1 of the first yarn feed roll P11 supported by one bobbin 25 with the second yarn end Y2 of the second yarn feed roll P12 supported by the other bobbin 25.

[0130] Similar to the above embodiment, the control unit 94 drives the first motor 622 and the second motor 632 to rotate the connector 8 (first yarn feed roll P11 and second yarn feed roll P12) to a position where the suction nozzle 614 can capture the first yarn end Y1 of the first yarn feed roll P11 and the second yarn end Y2 of the second yarn feed roll P12. Figure 17 Step S21).

[0131] Control unit 94 activates suction gun 611. Figure 17 Step S22). Thus, the suction gun 611 can attract and hold the yarn Y at the suction nozzle 614. The control unit 94 controls the arm 612, causing the suction nozzle 614 to capture (hold) the first yarn end Y1 of the first yarn feed roll P11. Figure 17 Step S23). Next, the control unit 94 controls the arm 612, such as... Figure 18A As shown, the suction nozzle 614 is moved to the first clamp 29A, and the yarn Y of the first yarn feed roll P11 is hooked onto the first clamp 29A. Figure 17 Step S24: First wire hanging action).

[0132] Next, while the yarn Y-hook of the first yarn feed roll P11 is hooked onto the first clamp 29A, the control unit 94 controls the arm 612, such as... Figure 18A As shown, the suction nozzle 614, holding the first yarn end Y1 of the first yarn feed roll P11, is moved to the first guide mechanism 67, hooking the yarn Y of the first yarn feed roll P11 onto the first guide mechanism 67. Based on the detection result of the potentiometer installed on the first guide mechanism 67, the control unit 94 adjusts the rotation amount (discharge amount) of the first yarn feed roll P11, pulling the yarn Y out of the first yarn feed roll P11 with a predetermined tension. Furthermore, while the yarn Y of the first yarn feed roll P11 is hooked onto the first guide mechanism 67, the control unit 94 controls the arm 612, causing the suction nozzle 614 to move to the connector mechanism 64, setting (guiding) the first yarn end Y1 of the first yarn feed roll P11 onto the connector mechanism 64. Figure 17 Step S25: First setup action).

[0133] Next, the control unit 94 causes the suction nozzle 614 to capture (hold) the second filament end Y2 of the second filament feed roll P12. Figure 17 Step S26). Next, the control unit 94 controls the arm 612, such as... Figure 18B As shown, the suction nozzle 614 is moved to the second clamp 29B, and the yarn Y hook of the second yarn feed roll P12 is hooked onto the second clamp 29B. Figure 17 Step S27: Second wire hanging action).

[0134] Next, while the yarn Y-hook of the second yarn feed roll P12 is hooked onto the second clamp 29B, the control unit 94 controls the arm 612, such as... Figure 18B As shown, the suction nozzle 614, holding the second filament end Y2, is moved to the second guide mechanism 68, hooking the filament Y of the second feed roll P12 onto the second guide mechanism 68. Based on the detection result of the potentiometer installed on the second guide mechanism 68, the control unit 94 adjusts the rotation amount (discharge amount) of the second feed roll P12, pulling the filament Y from the second feed roll P12 with a predetermined tension. Furthermore, while the filament Y of the second feed roll P12 is hooked onto the second guide mechanism 68, the control unit 94 controls the arm 612, causing the suction nozzle 614 to move to the connector mechanism 64, setting (guiding) the second filament end Y2 of the second feed roll P12 onto the connector mechanism 64. Figure 17 Step S28: Second setting action).

[0135] Next, the control unit 94 controls the twister 66 of the splicing device 60 to splice (connect) the first filament end Y1 of the first filament feed roll P11 and the second filament end Y2 of the second filament feed roll P12. Furthermore, the control unit 94 controls the cutters 664 and 665 of the splicing device 60 to cut off excess material from the splice portion of the first filament end Y1 of the first filament feed roll P11 and the second filament end Y2 of the second filament feed roll P12, including the portion held by the suction nozzle 614. Figure 17 Step S29: Connector action (connection action)).

[0136] Next, the control unit 94 stops the suction gun 611. Figure 17 Step S30). Next, the control unit 94 controls the arm 612, and after hooking (holding) the thread after the joint to the hook 615, moves the hook 615 to the outside of the joint mechanism 64. Thus, as Figure 19A As shown, the thread Y after the connector disengages from the connector mechanism 64, the first guide mechanism 67, and the second guide mechanism 68, and exits to the outside of the connector device 60. Figure 17 Step S31).

[0137] Next, the control unit 94 controls the first motor 622 and the second motor 632 to drive the first connector driver 621 and the second connector driver 631 to rotate, as follows: Figure 19B As shown, the first feed roll P11 and the second feed roll P12 are rotated. This eliminates the slack in the yarn Y after the connector, which is hooked onto the clamp 29. Figure 17 Step S32).

[0138] In the joint processing device 9A and the wire feeding device 100 involved in the modified example 1, the wire Y is locked by the first wire hanging action and the second wire hanging action on both sides of the first clamp 29A and the second clamp 29B, so a more stable locking state can be obtained.

[0139] (Variation Example 2)

[0140] As a further variation of the above-described embodiment, for example, such as Figure 20 As shown, four grippers 29C, 29D, 29E, and 29F can also be arranged in the Y direction between a pair of bobbins 25, 25 on the bobbin 20.

[0141] That is, the bobbin holder 20 involved in Modification Example 2 is configured to include: a pair of first inner layer side clamps (locking part, first locking part, first inner layer side locking part) 29C and a first outer layer side clamp (locking part, first locking part, first outer layer side locking part) 29D, which are disposed at a position away from the second yarn feed roll P12 supported by the other bobbin 25 than the first yarn feed roll P11 supported by the other bobbin 25, and are positioned with respect to the second yarn end Y2 and the first yarn end of the first yarn feed roll P11. Y1 is respectively provided; and a pair of second inner layer side clamps (locking part, second locking part, second inner layer side locking part) 29E and second outer layer side clamps (locking part, second locking part, second outer layer side locking part) 29F are arranged at a position close to the second yarn feed roll P12 supported by the other bobbin 25, and are respectively provided corresponding to the second yarn end Y2 and the first yarn end Y1 of the second yarn feed roll P12.

[0142] In this modified example 2, the first inner layer side clamp 29C, the first outer layer side clamp 29D, the second inner layer side clamp 29E, and the second outer layer side clamp 29F are fixed to the partition plate 24 via the bracket 24A. Furthermore, the orientations of the first inner layer side clamp 29C and the first outer layer side clamp 29D (the orientations of the pair of disc plates 291 and 292) are different from each other. Similarly, the orientations of the second inner layer side clamp 29E and the second outer layer side clamp 29F are different from each other.

[0143] The control unit 94 of the joint processing device 9A involved in Modification Example 2 controls the suction nozzle 614, the arm 612 and the twister 66 to perform joint processing including a first wire hanging action, a second wire hanging action, a first setting action, a second setting action and a jointing action (connection action).

[0144] In the first scenario (when unwinding yarn Y from the outer layer side of the second yarn feed roll P12), the first yarn-hanging action is as follows: the first yarn end Y1 of the first yarn feed roll P11 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the yarn Y of the first yarn feed roll P11 at the first outer layer side clamp 29D. The second yarn-hanging action in the first scenario is as follows: the second yarn end Y2 of the second yarn feed roll P12 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the yarn Y of the second yarn feed roll P12 at the second inner layer side clamp 29E. Furthermore, in the first scenario, both the first and second yarn-hanging actions are performed.

[0145] The first setting action in the first scenario is as follows: the first filament end Y1 of the first filament feed roll P11 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to place the first filament end Y1 of the first filament feed roll P11 onto the splicing mechanism 64. The second setting action in the first scenario is as follows: the second filament end Y2 of the second filament feed roll P12 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to place the second filament end Y2 of the second filament feed roll P12 onto the splicing mechanism 64. The splicing action in the first scenario is the action of connecting the first filament end Y1 of the first filament feed roll P11 with the second filament end Y2 of the second filament feed roll P12.

[0146] In the second scenario (when unwinding yarn Y from the outer layer side of the first yarn feed roll P11), the first yarn-hanging action is as follows: the second yarn end Y2 of the first yarn feed roll P11 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the yarn Y of the first yarn feed roll P11 at the first inner layer side clamp 29C. The second yarn-hanging action in the second scenario is as follows: the first yarn end Y1 of the second yarn feed roll P12 is held by the suction nozzle 614, and the suction nozzle 614 is moved by the arm 612 to stop the yarn Y of the second yarn feed roll P12 at the second outer layer side clamp 29F. Furthermore, in the second scenario, both the first and second yarn-hanging actions are performed.

[0147] The first setting action in the second scenario is as follows: the suction nozzle 614 holds the second filament end Y2 of the first filament feed roll P11, and the arm 612 moves the suction nozzle 614 so that the second filament end Y2 of the first filament feed roll P11 is positioned on the splicing mechanism 64. The second setting action in the second scenario is as follows: the suction nozzle 614 holds the first filament end Y1 of the second filament feed roll P12, and the arm 612 moves the suction nozzle 614 so that the first filament end Y1 of the second filament feed roll P12 is positioned on the splicing mechanism 64. The splicing action in the second scenario is the action of connecting the second filament end Y2 of the first filament feed roll P11 with the first filament end Y1 of the second filament feed roll P12.

[0148] Furthermore, in the configuration comprising a first inner layer side clamp 29C, a first outer layer side clamp 29D, a second inner layer side clamp 29E, and a second outer layer side clamp 29F, only one of the first wire-hanging action and the second wire-hanging action may be performed in each of the first and second scenes.

[0149] The following uses Figures 21-22. A series of actions, including joint processing and wire hanging processing, in the joint processing device 9A will be described in detail. Here, as in the above embodiment, the following case will be described as an example: when unwinding the wire Y from the outer layer side of the second wire feed roll P12 (in the first scenario described above), the first wire end Y1 of the first wire feed roll P11 and the second wire end Y2 of the second wire feed roll P12 are joined by the joint device 60.

[0150] Similar to the above embodiment, the control unit 94 drives the first motor 622 and the second motor 632 to rotate the connector 8 (first yarn feed roll P11 and second yarn feed roll P12) to a position where the suction nozzle 614 can capture the first yarn end Y1 of the first yarn feed roll P11 and the second yarn end Y2 of the second yarn feed roll P12. Figure 21 Step S41). The control unit 94 activates the suction gun 611. Figure 21 Step S42). Thus, the suction gun 611 can attract and hold the yarn Y at the suction nozzle 614. The control unit 94 controls the arm 612, causing the suction nozzle 614 to capture (hold) the first yarn end Y1 of the first yarn feed roll P11. Figure 21 Step S43). Next, the control unit 94 controls the arm 612, such as... Figure 22A As shown, the suction nozzle 614 is moved to the first outer layer side clamp 29D, and the yarn Y of the first yarn feed roll P11 is hooked onto the first outer layer side clamp 29D. Figure 21 Step S44: First wire hanging action).

[0151] Next, with the yarn Y of the first yarn feed roll P11 hooked onto the first outer layer side clamp 29D, the control unit 94 controls the arm 612 to move the suction nozzle 614, which holds the first yarn end Y1 of the first yarn feed roll P11, to the first guide mechanism 67, hooking the yarn Y of the first yarn feed roll P11 onto the first guide mechanism 67. Based on the detection result of the potentiometer provided on the first guide mechanism 67, the control unit 94 adjusts the rotation amount (discharge amount) of the first yarn feed roll P11 to pull the yarn Y out of the first yarn feed roll P11 with a specified tension. Furthermore, with the yarn Y of the first yarn feed roll P11 hooked onto the first guide mechanism 67, the control unit 94 controls the arm 612 to move the suction nozzle 614 to the connector mechanism 64, setting (guiding) the first yarn end Y1 of the first yarn feed roll P11 onto the connector mechanism 64. Figure 21 Step S45: First setup action).

[0152] Next, the control unit 94 causes the suction nozzle 614 to capture (hold) the second filament end Y2 of the second filament feed roll P12. Figure 21Step S46). Next, the control unit 94 controls the arm 612 to move the suction nozzle 614 to the second inner layer side clamp 29E, and hooks the yarn Y of the second yarn feed roll P12 onto the second inner layer side clamp 29E. Figure 21 Step S47: Second wire hanging action).

[0153] Next, with the yarn Y of the second yarn feed roll P12 hooked onto the second inner layer side clamp 29E, the control unit 94 controls the arm 612 to move the suction nozzle 614, which holds the second yarn end Y2 of the second yarn feed roll P12, to the second guide mechanism 68, hooking the yarn Y of the second yarn feed roll P12 onto the second guide mechanism 68. Based on the detection result of the potentiometer provided on the second guide mechanism 68, the control unit 94 adjusts the rotation amount (discharge amount) of the second yarn feed roll P12 to pull the yarn Y out of the second yarn feed roll P12 with a specified tension. Furthermore, with the yarn Y of the second yarn feed roll P12 hooked onto the second guide mechanism 68, the control unit 94 controls the arm 612 to move the suction nozzle 614 to the connector mechanism 64, setting (guiding) the second yarn end Y2 of the second yarn feed roll P12 onto the connector mechanism 64. Figure 21 Step S48: Second setting action). Furthermore, subsequent processing ( Figure 21 Steps S49 to S52) are the same as those in the above-described embodiments. Figure 12 Steps S8 to S11 are the same, so the explanation is omitted here.

[0154] Furthermore, when unwinding the yarn Y from the outer layer side of the first yarn feed roll P11 (when supplying the yarn Y to the processing section 3 from the outer layer side of the first yarn feed roll P11) (second scenario), the connector device 60 connects the first yarn end Y1 of the second yarn feed roll P12 with the second yarn end Y2 of the first yarn feed roll P11.

[0155] Specifically, the control unit 94 controls the arm 612 to cause the suction nozzle 614 to capture (hold) the second filament end Y2 of the first filament feed roll P11. Next, the control unit 94 controls the arm 612 as follows: Figure 22B As shown, the suction nozzle 614 is moved to the first inner layer side clamp 29C, and the yarn Y hook of the first yarn feed roll P11 is hooked onto the first inner layer side clamp 29C (first yarn hooking action).

[0156] Next, with the yarn Y of the first yarn feed roll P11 hooked onto the first inner layer side clamp 29C, the control unit 94 controls the arm 612 to move the suction nozzle 614, which holds the second yarn end Y2 of the first yarn feed roll P11, to the first guide mechanism 67, hooking the yarn Y of the first yarn feed roll P11 onto the first guide mechanism 67. Based on the detection result of the potentiometer installed on the first guide mechanism 67, the control unit 94 adjusts the rotation amount (discharge amount) of the first yarn feed roll P11 to pull the yarn Y out of the first yarn feed roll P11 with a specified tension. Furthermore, with the yarn Y of the first yarn feed roll P11 hooked onto the first guide mechanism 67, the control unit 94 controls the arm 612 to move the suction nozzle 614 to the connector mechanism 64, setting (guiding) the second yarn end Y2 of the first yarn feed roll P11 onto the connector mechanism 64 (first setting operation).

[0157] Next, the control unit 94 causes the suction nozzle 614 to capture (hold) the first yarn end Y1 of the second yarn feed roll P12. Next, the control unit 94 controls the arm 612 to move the suction nozzle 614 to the second outer layer side clamp 29F, hooking the yarn Y of the second yarn feed roll P12 onto the second outer layer side clamp 29F (second yarn hooking action).

Furthermore, the control unit 94 may not be provided in the roll changing device 9, but may be provided in a location away from the roll changing device 9 in a way that allows for wired or wireless communication.

[0165] In the splice processing apparatus 9A of the above embodiments and variations, examples with a first rotating mechanism 62 and a second rotating mechanism 63 have been described, but a splice apparatus 60 without the first rotating mechanism 62 and the second rotating mechanism 63 may also be provided. In this case, for example, in the splice processing apparatus 9A of the above embodiments, the operation of rotating the feed yarn package P1 is omitted. Figure 12 (Steps S1, S5, S7, and S11, etc.). Similarly, in the above-described modified examples, the action of rotating the wire feed roll P1 is omitted in the connector processing device 9A of the above embodiment.

[0166] In the above embodiments and variations, the example of the false twisting machine 1 was given as an example of a yarn processing apparatus, but it is not limited thereto. That is, although the example of an apparatus for performing twisted yarn processing (false twisting processing) was given as an example of the processing unit 3, it can also be applied to an apparatus for performing untwisted yarn processing (air jet processing).
