Yarn feed package mounting system

Abstract

A yarn feeding package mounting system, a yarn feeding package changing system, has a creel having a pair of bobbins, and a package changing device that mounts a yarn feeding package to the bobbins. The bobbins are each configured to rotate between a first rotational state in which the yarn feeding package is oriented in a direction in which a continuous filament is supplied toward a processing section, and a second rotational state in which the yarn feeding package is oriented in a direction in which the yarn feeding package is mountable by the package changing device. The package changing device rotates the bobbins to a third rotational state in which the bobbins are oriented in a direction between the first rotational state and the second rotational state after mounting the yarn feeding package to the bobbins in the second rotational state.

Description

TECHNICAL FIELD

[0001] One aspect of the present application relates to a yarn feed package mounting system. BACKGROUND

[0002] A false twist processing machine is known that performs false twist processing on a plurality of synthetic filaments supplied from a yarn feed package and winds the processed synthetic filaments in a winding device to form a wound package. For example, a false twist processing machine is disclosed in Patent Literature 1 (Japanese Patent Application Publication No. H7-68010) that has a creel that holds a plurality of yarn feed packages and a false twist processing device that performs false twist processing on yarn supplied from the yarn feed packages. A spool is provided in the creel, and the spool supports the yarn feed package so that it can rotate with an axis extending in the vertical direction as a rotation axis. Further, the spool can be switched between a first rotation state in which the yarn feed package is oriented so that the synthetic filaments are supplied to the false twist processing device of the false twist processing machine and a second rotation state in which the yarn feed package is oriented so that it can be mounted.

[0003] In the creel, there is a creel that has yarn feed package support portions composed of a pair of the above-described spools arranged in one direction. In such a creel, by connecting the synthetic filaments of the yarn feed package supported by one spool with the synthetic filaments of the yarn feed package supported by the other spool, even if the synthetic filaments of one yarn feed package run out, the synthetic filaments of the other yarn feed package can be fed, so the synthetic filaments can be continuously supplied to the false twist processing device.

[0004] In such a creel, the operator performs all of the mounting work of the yarn feed package supported by the spool, the cap mounting work of mounting a cap that protects the synthetic filaments unwound from the yarn feed package to a new yarn feed package, and the joint work (yarn end connecting work) of connecting the synthetic filaments of the yarn feed package supported by one spool with the synthetic filaments of the yarn feed package supported by the other spool by manual work. However, since a full yarn feed package is heavy, the mounting work of the yarn feed package places a particularly large burden on the operator. Therefore, it is considered to newly provide a mounting mechanism that mounts the yarn feed package to the spool.

[0005] However, a problem occurs when the pirn is left in the second rotational state after the feed package is mounted to the mounting mechanism. That is, in order to achieve compactness of the creel, the feed package support portions are arranged at a reduced interval from each other in the arrangement direction. Here, when the pirn contained in one of the feed package support portions and arranged on the side of the feed package of the other is set as a first pirn, and the pirn contained in the other of the feed package support portions and arranged on the side of the feed package of the one is set as a second pirn, the feed packages sometimes come into contact with each other when the first pirn and the second pirn respectively support the feed packages of a diameter or more in the second rotational state. In other words, when one of the first pirn and the second pirn supports the feed package to be in the second rotational state, the other of the first pirn and the second pirn cannot mount the feed package.

[0006] Therefore, it is considered to rotate the pirn to the first rotational state after the feed package is mounted to the mounting mechanism. However, if the pirn is brought to the first rotational state, the operator cannot distinguish whether the cap mounting operation and the joint operation are completed, as in the state where the yarn is supplied to the false twist processing device after the cap mounting operation and the joint operation are completed. Therefore, a problem occurs in which the operator misses the cap mounting operation or the joint operation. SUMMARY

[0007] Therefore, an object of one aspect of the present application is to provide a feed package mounting system that can achieve compactness of the creel, and the operator can easily recognize the state of the operation after the feed package is mounted to the pirn by the mounting mechanism, so that the operator can be prevented from missing the operation.

[0008] The yarn feeding package mounting system of one aspect of the present application is provided with: a creel having a pair of bobbins that support yarn feeding packages in which conjugate filaments supplied to a yarn processing device are wound so as to be rotatable, and that enable the conjugate filaments of the yarn feeding package supported by one of the bobbins to be connected to the conjugate filaments of the yarn feeding package supported by the other of the bobbins, and when the conjugate filaments of the yarn feeding package of one side are used up, the conjugate filaments of the yarn feeding package of the other side can be supplied to the yarn processing device; and a mounting mechanism that mounts the yarn feeding packages to the bobbins, the pair of bobbins are respectively provided so as to be rotatable between a first rotational state in which the yarn feeding packages are oriented in a direction in which the conjugate filaments are supplied to the yarn processing device, and a second rotational state in which the yarn feeding packages are oriented in a direction in which the yarn feeding packages can be mounted by the mounting mechanism, the mounting mechanism rotates the bobbins to a third rotational state in which the bobbins are oriented in a direction between the first rotational state and the second rotational state after the bobbins mount the yarn feeding packages in the second rotational state, the creel is provided with a plurality of yarn feeding package support portions that support the pair of bobbins as a group, and the plurality of bobbins that constitute the plurality of yarn feeding package support portions are arranged in one direction, in the yarn feeding package support portions that are adjacent to each other, when a bobbin that is included in one of the yarn feeding package support portions and that is disposed on the side of the other of the yarn feeding package support portions is provided as a first bobbin, and a bobbin that is included in the other of the yarn feeding package support portions and that is disposed on the side of the one of the yarn feeding package support portions is provided as a second bobbin, the first bobbin and the second bobbin are provided so that when the first bobbin and the second bobbin respectively support yarn feeding packages of a prescribed diameter or more, when the first bobbin and the second bobbin are respectively in the second rotational state, the yarn feeding packages contact each other, and when one of the first bobbin and the second bobbin is in the second rotational state and the other of the first bobbin and the second bobbin is in the third rotational state, the yarn feeding packages of the prescribed diameter or more do not contact each other.

[0009] In the yarn feeding package mounting system of this configuration, when the first bobbin and the second bobbin are respectively in the second rotational state and support the yarn feeding packages of the prescribed diameter or more, the first bobbin and the second bobbin are disposed in close proximity to each other in a manner in which the yarn feeding packages contact each other, and thus, the compactness of the creel is achieved. Furthermore, in the yarn feeding package mounting system of this configuration, after one of the first bobbin and the second bobbin in the second rotational state mounts a yarn feeding package, the mounting mechanism does not leave the bobbin as is but rotates the bobbin to the third rotational state. Thus, the other of the first bobbin and the second bobbin can also be mounted with a yarn feeding package. Furthermore, the mounting mechanism rotates one of the first bobbin and the second bobbin to the third rotational state that is different from the first rotational state, and thus, the operator can easily recognize that the cap mounting work or the joint work has not been completed and is in a state in which these works should be performed. As a result, it is possible to prevent omission of the work of the operator after the mounting mechanism mounts the bobbins with the yarn feeding packages.

[0010] In the yarn feed package mounting system of one aspect of the present application, the mounting mechanism can also mount a new yarn feed package to the bobbin after recovering the used yarn feed package from the bobbin. In this configuration, not only can a yarn feed package be mounted to the bobbin, but also a used yarn feed package can be recovered.

[0011] In the yarn feed package mounting system of one aspect of the present application, the creel can also have: a shaft portion extending in the vertical direction; a rotation portion supporting the bobbin so as to be rotatable with respect to the shaft portion; and a rotation restriction portion restricting rotation of the rotation portion in a first rotation state, a second rotation state, and a third rotation state. In this configuration, positioning by the mounting mechanism into the second rotation state and the third rotation state becomes easy, and positioning by the operator into the first rotation state becomes easy.

[0012] In the yarn feed package mounting system of one aspect of the present application, the rotation restriction portion can have: a locking portion provided to one of the fixed portion and the rotation portion that is provided so as to be non-rotatable with respect to the shaft portion; and a locked portion provided to the other of the fixed portion and the rotation portion, for the locking portion to lock. In this configuration, the yarn feed package support portion can be positioned by a simple configuration.

[0013] In the yarn feed package mounting system of one aspect of the present application, the locking portion can be a protrusion, and the locked portion can be a groove for the protrusion to lock. In this configuration, the yarn feed package support portion can be positioned by a simple configuration.

[0014] In the yarn feed package mounting system of one aspect of the present application, the locking portion can be a protrusion, and the locked portion can be a groove for the protrusion to lock. In this configuration, the yarn feed package support portion can be positioned by a simple configuration.

[0015] According to one aspect of the present application, the creel can be compacted, and the operator can easily recognize the operation state after the yarn feed package is mounted to the bobbin by the mounting mechanism, so that omission of the operation by the operator can be prevented.

DETAILED DESCRIPTION

[0044] Hereinafter, a preferred embodiment of one aspect of the present application will be explained in detail with reference to the attached drawings. In addition, in the explanation of the drawings, the same or equivalent elements are denoted by the same symbols, and repeated explanation will be omitted.

[0045] As Figure 1As shown, in one embodiment, a bobbin holder 20 is installed on a false twisting machine 1. Furthermore, in another embodiment, a yarn feed roll changing system (yarn feed roll mounting system) 100 includes the bobbin holder 20 and a roll changing device (mounting mechanism) 9. In the following description, the "Z direction" shown in the figures 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 also the direction orthogonal to both the X and Z directions.

[0046] The false-twist processing machine 1 processes filaments (synthetic fibers) Y supplied from multiple feed packages P1 to produce a wound package P2. The filaments Y are, for example, synthetic fibers composed of thermoplastic synthetic fibers such as polyester or polyamide. The feed packages P1 are formed by winding partially oriented filaments (POY) onto a feed bobbin B1. The wound package P2 is formed by winding drawn textured filaments (DTY) onto a winding bobbin B2. In other words, the false-twist processing machine 1 processes the partially oriented filaments Y to produce drawn textured filaments.

[0047] The false twisting processing machine 1 includes a feeding section 2, a processing section (thread processing device) 3, and a winding section 4. The feeding section 2, processing section 3, and winding section 4, described later, are each configured on the travel surface of the thread Y, which is arranged in the thread channel from the 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 direction of the long side of the body) on the paper.

[0048] The feeding section 2 supplies yarn Y to the processing section 3. The feeding section 2 has a bobbin holder 20 that holds multiple yarn feed rolls P1. Figure 1 as well as Figure 2 As shown, the tube frame 20 includes a tube base 21, a first support column 22, a second support column (shaft) 23, a partition plate 24, and a bobbin 25. The tube 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 tube base 21.

[0049] The first support 22 extends along the Z direction (vertical direction). The first support 22 are arranged at equal intervals in the Y direction. The first support 22 is located 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 section 3, which will be described in detail later, is located, and is the side where the yarn Y is fed to the processing section 3 where the false twisting process is performed.

[0050] 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 other side F2 of the roll frame 20 in the X direction. The other side F2 in the X direction is the side where the winding changer 9, described in detail later, travels, and is also 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.

[0051] The separator 24 is configured to span between the first support 22 and the second support 23. The separator 24 is a plate-shaped component, arranged at predetermined intervals in the Z direction. The separator 24 prevents the yarn feed package P1 from falling off the bobbin 25.

[0052] 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, the bobbins 25 are arranged in pairs corresponding to the two sets of second posts 23, and multiple sets (pairs) of bobbins 25 are arranged in the Y direction.

[0053] In this bobbin 25 configuration, the yarn Y from the feed roll P1 supported on one of the bobbins (first bobbin) 25 can be connected to the yarn Y from the feed roll P1 supported on the other bobbin (second bobbin) 25. Specifically, the outer end of the yarn Y from the feed roll P1 supported on one of the bobbins 25 is connected to the inner end of the yarn Y from the feed roll P1 supported on the other bobbin 25, or the inner end of the yarn Y from the feed roll P1 supported on one of the bobbins 25 is connected to the outer end of the yarn Y from the feed roll P1 supported on the other bobbin 25. Thus, a single yarn Y is supplied from the two feed rolls P1, P1 respectively supported on the pair of bobbins 25, 25. That is, the yarn Y can be continuously supplied to the processing unit 3.

[0054] like Figure 3A , Figure 3B , Figure 4A as well as Figure 4BAs shown, the bobbin 25 includes a feed roll support 251, a bobbin body (rotating part) 252, a body support (rotating part) 253, a rotation transmission part 254, and a fixing part 255. The feed roll support 251 supports the feed roll P1 so that it can rotate. The feed roll support 251 is a pair of rod-shaped members extending in one direction. The pair of feed roll support 251 are arranged at a predetermined interval in a manner that extends in one direction and is parallel to each other. The feed roll support 251 supports the feed roll P1 by inserting the rod-shaped members extending from the base end to the front end into the hole formed in the feed spool B1 of the feed roll P1. The bobbin 25 supports the feed roll P1 at two points by the two feed roll support 251, 251.

[0055] The bobbin body 252 supports two feed roll supports 251. The bobbin body 252 is configured to allow the feed roll supports 251 to rotate about a rotation axis extending along the Z-axis. An insertion hole 252A is formed in the bobbin body 252. The second support 23 of the bobbin holder 20 is inserted through the insertion hole 252A.

[0056] The main support portion 253 is a cylindrical component extending in one direction. One end of the main support portion 253 in the extending direction is connected to the bobbin body portion 252. The main support portion 253 and the bobbin body portion 252 are integrally formed. The main support portion 253 supports the yarn feed package support portion 251 so that it can rotate relative to the second support post 23. The hollow portion of the main support portion 253 communicates with the insertion hole 252A of the bobbin body portion 252. The second support post 23 of the bobbin holder 20 is inserted into the insertion hole 252A of the bobbin body portion 252 and the hollow portion of the main support portion 253.

[0057] The main support portion 253 is configured to be able to rotate within a range R (refer to) with the first rotation state C1 and the second rotation state C2 as the rotation ends. Figure 5A The first rotation state C1 is a state in which the wire feeding roll P1 is supported in such a way that it can supply the wire Y to the processing unit 3 that processes the wire Y. The second rotation state C2 is a state in which the wire feeding roll P1 is supported in such a way that it can be replaced (the wire feeding tube B1 is retracted and the wire feeding roll P1 is installed).

[0058] The rotation transmission section 254 is a Maltese wheel constituting the Maltese mechanism. The rotation transmission section 254 is connected to the other end of the main support section 253 in the extending direction. The rotation transmission section 254 is integrally formed with the bobbin body section 252. The rotation transmission section 254 is connected via a rotating device 932 (see below). Figure 7 Rotation drive 932A (refer to) Figure 7Driven by the rotation of the spindle core 254, the spindle core body 252 rotates. This causes the feed coil support portions 251 to rotate.

[0059] The fixing part 255 is fixed to the second support column 23 without rotation. The rotation limiting part 256 temporarily restricts (positions) the rotation of the main support part 253 relative to the second support column 23 in a predetermined state. The rotation limiting part 256 temporarily restricts the rotation of the main support part 253 relative to the second support column 23 in a first rotation state C1, a second rotation state C2, and a third rotation state C3, which is a rotation state between the first rotation state C1 and the second rotation state C2. The main support part 253, whose rotation is restricted by the rotation limiting part 256, is released by the operator applying force in the rotation direction.

[0060] The rotation limiting part 256 is composed of a protrusion (locking part) 257 and a groove (locked part) 258. The protrusion (locking part) 257 is provided on one of the bobbin body part 252 and the fixing part 255, and the groove (locked part) 258 is provided on the other of the bobbin body part 252 and the fixing part 255 and is locked by the protrusion 257. In this embodiment, the protrusion 257 forming the rotation limiting part 256 is provided on the bobbin body part 252, and the groove 258 is provided on the fixing part 255. Figure 5A As shown, the fixing part 255 has a groove 258 that causes the main body support part 253 (hairpin 25) to be in a first rotation state C1 when the locking protrusion 257 is engaged, a groove 258 that causes the main body support part 253 to be in a second rotation state C2, and a groove 258 that causes the main body support part 253 to be in a third rotation state C3.

[0061] like Figure 5B As shown, the groove 258 that enables the main support portion 253 to reach a first rotational state C1 when the protrusion 257 is engaged has a first engaging surface 258A, a second engaging surface 258B, and a third engaging surface 258C. The second engaging surface 258B is formed on the side that allows the main support portion 253 to rotate toward the second rotational state C2. The first engaging surface 258A is a plane extending in the vertical direction. The second engaging surface 258B is an inclined surface. The third engaging surface 258C is a horizontal surface. With this shape of the groove 258, the protrusion 257 can slide into or out of the groove 258 only from the side of the second engaging surface 258B, preventing the protrusion 257 from exiting from the side of the first engaging surface 258A of the groove 258, and enabling the protrusion 257 to engage with the groove 258.

[0062] Although not shown, the groove 258 that enables the main support portion 253 to enter the second rotational state C2 when the protrusion 257 is engaged also has a first engaging surface 258A, a second engaging surface 258B, and a third engaging surface 258C. The second engaging surface 258B is formed on the side that causes the main support portion 253 to rotate toward the first rotational state C1. The first engaging surface 258A is a plane extending in the vertical direction. The second engaging surface 258B is an inclined surface. The third engaging surface 258C is a horizontal surface. With this shape of the groove 258, the protrusion 257 can slide into or out of the groove 258 only from the side of the second engaging surface 258B, preventing the protrusion 257 from exiting from the side of the first engaging surface 258A of the groove 258, and enabling the protrusion 257 to engage in the groove 258.

[0063] like Figure 5C As shown, the groove 258 that enables the main support portion 253 to reach a third rotational state C3 when the protrusion 257 is engaged has a fourth engaging surface 258D, a fifth engaging surface 258E, and a sixth engaging surface 258F. The fourth engaging surface 258D is formed on the side that allows the main support portion 253 to rotate toward the first rotational state C1, and is an inclined surface. The fifth engaging surface 258E is formed on the side that allows the main support portion 253 to rotate toward the second rotational state C2, and is an inclined surface. The sixth engaging surface 258F is a horizontal surface. With this shape of the groove 258, the protrusion 257 can slide from the side of the fourth engaging surface 258D and enter or exit the groove 258, the protrusion 257 can slide from the side of the fifth engaging surface 258E and enter or exit the groove 258, and the protrusion 257 can be engaged in the groove 258.

[0064] like Figure 2 As shown, the bobbins 25 are arranged in the Y direction. The main body support 253 rotates in the following manner: Figure 9A As shown in the second bobbin from the left 25, in the first rotation state C1, the front end of the feeding winding support 251 faces the X-direction side F1, as shown. Figure 9B As shown in the second bobbin 25 from the left, in the second rotation state C2, the front end of the feeding winding support 251 faces the other side F2 in the X direction, as... Figure 10A As shown in the second bobbin from the left 25, the front end of the feeding coil support 251 faces the Y direction in the third rotation state C3.

[0065] In addition, for bobbin 25, such as Figure 10BAs shown in the second and third bobbins from the left, when one of the bobbins 25 in the pair is supported by a feed roll P1 of a specified diameter, it prevents the installation of a feed roll P1 of a specified diameter or larger on the other bobbin 25. More specifically, when the relationship D≦r2+r3 is present, when one of the bobbins 25 in the pair is supported by a feed roll P1 of a specified diameter r2, it prevents the installation of a feed roll P1 of a specified diameter r3 on the other bobbin 25.

[0066] D: The distance between the second bobbin 25 from the left (the center of the second pillar 23) and the third bobbin 25 from the left (the center of the second pillar 23).

[0067] r2: Radius of the feed roll P1 supported by the second bobbin from the left 25.

[0068] r3: Radius of the feed coil P1 supported by the third bobbin from the left 25.

[0069] That is, the pair of bobbins 25, 25 are arranged with the Y-direction spacing reduced so that the feed rolls P1, P1 supported when they are in the second rotation state C2 are in contact with each other.

[0070] On the other hand, for bobbin 25, such as Figure 11A As shown in the second and third bobbin 25 from the left, they are configured such that the yarn feed package P1 of the bobbin 25 supported in the second rotational state C2 (which is one of the aforementioned pair) and the yarn feed package P1 of the bobbin 25 supported in the third rotational state C3 (which is the other of the aforementioned pair) do not contact each other, as... Figure 11B As shown in the second bobbin 25 from the left and the third bobbin 25 from the left, they are configured such that the yarn feed roll P1 supported on the bobbin 25 in the first rotation state C1, which is one of the above pair, and the yarn feed roll P1 supported on the bobbin 25 in the third rotation state C3, which is the other of the above pair, do not come into contact with each other.

[0071] Processing section 3 performs false twisting on the yarn Y supplied from feeding section 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 twist 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 twist device 34, the second heating device 35, and the feed rollers 36 (feed rollers 361 to 363) are each independently arranged relative to each yarn Y supplied from the feed unit 2, and are arranged in a row in the Y direction.

[0072] The anti-twist guide 31 prevents the twist imparted to the yarn Y by the false twist device 34 (described later) from propagating upstream of the anti-twist guide 31 in the direction of yarn travel. The first heating device 32 heats the yarn Y fed from the feed 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.

[0073] 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) is configured to include a drive roller and a driven roller. Each feed roller 36 is also arranged in a row in the Y direction.

[0074] The feeding speed of the yarn Y conveyed by the feed roller 362 is faster than that of the feed roller 361, and the yarn Y is stretched between the feed rollers 361 and 362. The feeding speed of the yarn Y conveyed by the feed roller 363 is slower than that of the feed roller 362, and the yarn Y is relaxed between the feed rollers 362 and 363.

[0075] In the processing section 3 configured as described above, the filament Y stretched between the feed rollers 361 and 362 is twisted by the false twisting device 34. The twist formed 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 direction of filament travel. After being heat-set by the first heating device 32, the stretched and twisted filament Y is cooled by the cooling device 33. Downstream of the false twisting device 34, the filament Y is untwisted, but through the aforementioned heat setting, each filament is maintained in a false twisted state.

[0076] While the yarn Y is slack between the feed rollers 362 and 363, it 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.

[0077] The winding section 4 includes a winding device 41, a package storage container 42, and a doffing device (not shown). The winding device 41 winds the yarn Y, which has undergone false twisting processing by the processing section 3, to form a wound package P2. The package storage container 42 stores the wound package P2 formed by the winding device 41. The doffing device removes the wound package P2 formed by the winding device 41, transfers the wound package P2 to the package storage container 42, and installs an empty winding bobbin B2 into the winding device 41; and so on.

[0078] 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 ground 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, and a control unit 94 (see reference) that controls the operation of each unit. Figure 8 ).

[0079] 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 along the Z direction, and a drive mechanism (not shown) for driving the work platform.

[0080] Holding unit 92 holds multiple (e.g., four) feed rolls P1. Holding unit 92 receives feed rolls P1 from a roll replenishment device (not shown) and temporarily holds the feed rolls P1, and supplies feed rolls P1 to changing unit 93. Holding unit 92 is configured to rotate within a range of approximately 90°. More specifically, holding unit 92 is configured to be able to rotate between the replenishment position where it receives feed rolls P1 from the roll replenishment device and the supply position where it supplies feed rolls P1 to changing unit 93. Figure 6 Rotate between the positions shown.

[0081] The replacement unit 93 replaces the feed bobbin B1 and the feed roll P1 in the bobbin 25. Specifically, the replacement unit 93 retrieves the feed bobbin B1 from the bobbin 25 (see reference). Figure 1 ), and install the wire feed roll P1 on the bobbin 25. Replace the adjacent grounding setting of the replacement unit 93 and the holding unit 92. 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. Additionally, in Figure 6 The description of the rotating device 932, the recovery device 933, the supply device 934, and the rotating table 936 is omitted.

[0082] The base 931 supports the rotating device 932, the recovery device 933, the supply device 934, and the rotary table 936. 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 rotation drive 932A and a rotating arm 932B.

[0083] The rotation drive 932A causes the rotation transmission part 254 of the bobbin 25 (for example, see reference) to rotate the bobbin 25. Figure 3A (etc.) Rotation. Rotation drive 932A is a Maltese drive component constituting the Maltese mechanism. Rotation drive 932A is rotated by a motor (not shown). Rotation arm 932B supports rotation drive 932A. Rotation arm 932B is configured to swing in the horizontal direction. Rotation arm 932B is driven, for example, by a motor or cylinder (not shown). Rotation device 932 is configured to correspond to one of the bobbins 25 in a pair arranged in the bobbin case 20, and the other bobbin 25, respectively.

[0084] When the bobbin 25 is fitted with the yarn feed package P1, the rotating device 932 rotates the bobbin 25, changing its orientation. More specifically, the rotating device 93 swings the rotating arm 932B, engaging the rotation drive 932A with the rotation transmission part 254 of the bobbin 25. When the rotation drive 932A is engaged with the rotation transmission part 254, the rotating device 932 rotates the rotation drive 932A in one direction. In the bobbin 25, when the rotation transmission part 254 rotates, the main support part 253 rotates. As a result, the bobbin 25 rotates, and the front end of the yarn feed package support part 251 faces the changing unit 93.

[0085] A recovery device 933 is provided on a rotary table 936 rotatably supported on a base 931. The recovery device 933 recovers the bobbin 25 from the bobbin. The recovery device 933 has a bobbin support 933A that supports the bobbin B1. The recovery device 933 supports the bobbin B1 by advancing the bobbin support 933A when the bobbin B1 is not supported on the bobbin 25, and recovers the bobbin B1 from the bobbin 25 by retracting the bobbin support 933A when the bobbin B1 is supported on the bobbin 25.

[0086] A feeding device 934 is provided on a rotary table 936 that is rotatably supported on a base 931. The feeding device 934 supplies a yarn feed package P1 to the bobbin 25. The feeding device 934 has a yarn feed package supply section 934A that supports the yarn feed package P1. The feeding device 934 installs the yarn feed package P1 onto the bobbin 25 by advancing the yarn feed package supply section 934A while the yarn feed package P1 is supported on the bobbin 25, and supplies the yarn feed package P1 to the bobbin 25 by retracting the yarn feed package supply section 934A while the yarn feed package P1 is not supported on the bobbin 25.

[0087] The rotary table 936 is rotatably supported on the base 931. When the feed bobbin B1 is retracted, the rotary table 936 rotates with the feed bobbin support 933A facing the front of the bobbin 25. Furthermore, when the feed package P1 is supplied, the rotary table 936 rotates with the feed package supply 934A facing the front of the bobbin 25.

[0088] like Figure 8 As 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 each part of the traveling unit 90, the lifting unit 91, the holding unit 92, and the changing unit 93. Furthermore, by loading prescribed computer software into the hardware such as the CPU and main memory, the functions of the control unit 94 are executed under the control of the CPU.

[0089] As described above, the roll changing device 9 is installed on the F2 side of the bobbin holder 20 in a manner that allows it to travel along the Y direction. It removes the used feed roll P1 (feed bobbin B1) supported on the bobbin 25 and replaces it with the (new) feed roll P1 before use. When replacing the feed roll P1, the control unit 94 controls the roll changing device 9 to rotate the main support 253 so that the bobbin 25 (refer to the first rotation state C1) is in a rotating state C1. Figure 9A The second bobbin from the left (25) becomes the second rotation state C2 (refer to...). Figure 9B (The second bobbin from the left, 25). Next, the control unit 94 controls the package changing device 9 to change from the used feed package P1 to the feed package P1 before use. Next, the control unit 94 rotates the main body support 253 so that the bobbin 25, which is in the second rotation state C2, becomes the third rotation state C3 (see reference). Figure 10A (The second bobbin from the left, 25). More specifically, the control unit 94 drives the rotation drive member 932A of the rotation device 932, causing the rotation transmission unit 254 to rotate, and causing the bobbin body 252 to rotate.

[0090] The bobbin holder 20 with the above configuration can support the wire feed package P1 in the first rotating state C1 (refer to) in a manner that allows the wire Y to be supplied to the processing section 3 for processing the wire Y. Figure 9A The second bobbin from the left (25) and the second rotating state C2 (refer to the second rotation state) in which the feed coil P1 is supported in a manner that allows for the replacement of the feed coil P1. Figure 9BThe rotation of the main body support 253 is temporarily restricted (positioned) under the second bobbin from the left (25), and it is also possible to achieve a third rotation state (refer to) between the first rotation state C1 and the second rotation state C2. Figure 10A The rotation of the main body support 253 is temporarily restricted (positioned) under the second bobbin from the left (25).

[0091] Figure 12 Viewed from the other side F2 (i.e., from the direction the operator is working), the support is located at... Figure 10A The diagram shows the bobbin 25 in its feed coil P1 state. The observation methods when viewing the bobbin 25 from the other side F2 in the X direction are quite different in the feed coil P1 of the bobbin 25 supported in the first rotation state C1 and the feed coil P1 of the bobbin 25 supported in the third rotation state C3. Therefore, the operator can distinguish the bobbin 25 in the third rotation state C3 from the bobbin 25 in the first rotation state C1 and the second rotation state C2. In other words, although the installation work of the feed coil P1 has been completed, the cap installation work or the splicing work has not yet been completed, and the operator can easily identify the feed coil P1 supported on the bobbin 25 in the state where these operations should be performed.

[0092] To visually distinguish the wire feed reel P1 as the joint object, it is considered that after changing the wire feed reel P1, the bobbin 25 will not switch to the first rotation state C1 but will remain in the second rotation state C2 at the time of replacement. However, as Figure 10B As shown, the yarn feed package P1 of the bobbin 25 mounted in the second rotation state C2 sometimes prevents adjacent bobbins 25 from reaching the second rotation state C2. This is because, in order to suppress the expansion of the bobbin 20 in the Y direction, the spacing between the bobbins 25 in the Y direction is reduced. In the bobbin 20 of this embodiment, the bobbins 25 are arranged such that the yarn feed packages P1 supporting adjacent bobbins 25 in the second rotation state C2 in the Y direction are in contact with each other, and the yarn feed packages P1 supporting adjacent bobbins 25 in the second rotation state C2 are arranged such that the yarn feed packages P1 supporting bobbins 25 in the third rotation state C3 are not in contact with each other. As a result, the expansion of the bobbin 20 in the Y direction can also be suppressed.

[0093] like Figure 13A as well as Figure 13B As shown, the cap installation or splicing operation described above is performed manually by the operator. The cap installation operation is the operation of covering the front end of the wire feeding coil support 251 with a cap 259. In the aforementioned conventional bobbin holder 520, as... Figure 13BAs shown, with the bobbin 25 in its first rotating state C1, the front end of the feeding package support 251 faces the X direction on one side F1. In this state, the operator performs the cap installation operation. At this time, the width (length) of the space in which the operator inserts their hand to perform the cap installation operation from the other side F2 is L2.

[0094] In contrast, in the tube holder 20 of this embodiment, such as Figure 13A As shown, with the bobbin 25 in its third rotational state C3, the front end of the yarn feeding support 251 faces the Y direction, and the operator performs the cap installation operation in this state. At this time, the width (length) of the space for the operator to insert their hand from the other side F2 to perform the cap installation operation is L1, which is longer than L2. Therefore, in the bobbin holder 20 of this embodiment, the workability during the cap installation operation can be improved.

[0095] Alternatively, the splicing operation can be performed while the bobbin 25, which has reached the third rotating state C3 after the installation of the wire feeding coil P1 has ended, remains in the third rotating state C3 (see reference). Figure 10A Alternatively, the operator can bring the bobbin 25 to its first rotating state C1 before performing the splicing operation (see [reference]). Figure 9A ).

[0096] The above describes one aspect of the present invention, but this aspect is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from its spirit.

[0097] (Variation Example 1)

[0098] Regarding the bobbin 25 in the above embodiment, an example has been described where a protrusion 257, serving as a locking portion, is formed in the bobbin body 252, which is a rotating portion, and a groove 258, serving as a locking portion, is formed in the fixing portion 255. However, one aspect of the present invention is not limited to this. For example, such as Figure 14A , Figure 14B , Figure 15A as well as Figure 15B As shown, in the modified example 1, the bobbin 25A has a cam 260 as a locking part in the bobbin body 252, which is a rotating part, and a protrusion 257A as a locking part in the fixing part 255A.

[0099] The cam 260 is integrally disposed on the bobbin body 252. A protrusion 261 protruding downward in an annular shape is formed on the periphery of the cam 260. The protrusion 261 has a groove 262 that causes the main body support 253 to be in a first rotation state C1 when the locking protrusion 257A is engaged, a groove 262 that causes the main body support 253 to be in a second rotation state C2, and a groove 262 that causes the main body support 253 to be in a third rotation state C3. Even with the bobbin 25A constructed in such a modified example 1, the rotation of the main body support 253 can be temporarily restricted (positioned) not only in the first rotation state C1, in which the feed roll P1 is supported in a manner that allows the feed roll Y to be supplied to the processing section 3 that processes the feed roll Y, and in the second rotation state C2, in which the feed roll P1 is supported in a manner that allows the feed roll P1 to be replaced, but also in the third rotation state C3, a rotation state between the first rotation state C1 and the second rotation state C2.

[0100] (Variation Example 2)

[0101] Regarding the bobbin 25A of Modified Example 1, an example has been described where a cam 260, serving as a locking portion, is provided in the bobbin body 252, which is a rotating portion, and a protrusion 257A, serving as a locking portion, is provided in the fixing portion 255A. However, one aspect of the present invention is not limited to this. For example, as... Figure 16A as well as Figure 16B As shown, in modified example 2, the bobbin 25B may also have a recess 270 as a locking part provided in the main body support part 253 which is a rotating part, and a plunger (protrusion) 280 as a locking part provided in the fixing part 255B.

[0102] The main support portion 253B has recesses 270 that, when the locking plunger 280 is engaged, cause the main support portion 253B to be in a first rotational state C1, a second rotational state C2, and a third rotational state C3. Even with the bobbin 25B configured in this modified example 2, the rotation of the main support portion 253B can be temporarily restricted (positioned) not only in the first rotational state C1, in which the yarn feed package P1 is supported in a manner that allows the yarn Y to be supplied to the processing unit 3 for processing the yarn Y, and in the second rotational state C2, in which the yarn feed package P1 is supported in a manner that allows the yarn feed package P1 to be replaced, but also in the third rotational state C3, a rotational state between the first rotational state C1 and the second rotational state C2, that is, the rotation of the main support portion 253B can be temporarily restricted (positioned).

[0103] (Other variations)

[0104] In the above embodiments and variations, an example with a roll changing device 9 that is configured to travel along the roll rack 20 has been described. However, even if the roll rack 20 does not have the roll changing device 9, the same effect as the above embodiments and variations can be obtained.

[0105] In the above embodiments and variations, an example has been described of a wire feed roll replacement system 100 in which the present invention is applied to a wire feed roll P1 after the used wire feed roll P1 is recovered from the bobbin 25 and a new wire feed roll P1 is installed on the bobbin 25. However, the present invention can also be applied to a wire feed roll installation system in which a new wire feed roll P1 is installed on the bobbin 25 without recovering the used wire feed roll P1 from the bobbin 25.

[0106] In the above embodiments and variations, an example of a device for performing twisting (false twisting) was described as an example of the processing unit 3. It can also be applied to a device for performing untwisted yarn processing (air jet processing).
