Description

The present invention relates to pegs, package changing devices and yarn processing systems.

Patent Document 1 describes a false twisting machine as a textile machine that winds up treated synthetic yarns. The false twisting machine includes a creel stand equipped with multiple pegs that support the yarn supply package, a false twisting device that applies false twist to the synthetic yarn supplied from the yarn supply package, and a A winding device that winds up the synthetic yarn to form a winding package.

In creel stands, pegs are used in pairs to provide a continuous supply of yarn. In this configuration, the yarn on the inner layer side of the yarn supply package supported by one peg is connected to the yarn on the outer layer side of the yarn supply package supported on the other peg. Thereby, in the creel stand, even if one yarn supply package runs out of yarn, yarn is supplied from the other yarn supply package, so that yarn can be continuously supplied.

That is, the yarn splicing device 60 adjusts the amount of rotation (feeding amount) of the yarn supply package P1 based on the detection result of the potentiometer, and draws out the yarn Y from the yarn supply package P1 with a predetermined tension.

The yarn splicing operation of the yarn splicing device 60 will be explained. Specifically, the yarn splicing device 60 connects the first yarn end Y1 on the outer layer side of the yarn supply package P1 supported by the first peg 24a and the inner layer of the yarn supply package P1 supported by the second peg 24b. An example of a case where the yarn is spliced with the second yarn end Y2 on the side will be described.

When the yarn splicing device 60 starts the yarn splicing operation, as shown in FIG. 14, the first rotation mechanism 62 operates the first peg 24a, and the second rotation mechanism 63 operates the second peg 24b. The adapter 10 is rotated to a position where the first yarn end Y1 and the second yarn end Y2 can be captured by the suction portion 61a. Specifically, in the first rotation mechanism 62, the first yarn splicing driver 62a is engaged with the first wheel 25j of the first peg 24a, and the first motor 62b is driven to rotate the first yarn splicing driver 62a. let Similarly, in the second rotation mechanism 63, the second yarn splicing driver 63a is engaged with the first wheel 25j of the second peg 24b, and the second motor 63b is driven to rotate the second yarn splicing driver 63a. When the first yarn splicing driver 62a and the second yarn splicing driver 63a rotate, the yarn feeding package P1 supported by the first peg 24a and the second peg 24b rotates, and the adapter 10 rotates accordingly. The yarn splicing device 60 detects a detection object (not shown) provided on the adapter 10 with a sensor (not shown), controls the first motor 62b and the second motor 63b based on the detection result of the sensor, and 10 to the specified position.

When the adapter 10 is rotated, the yarn splicing device 60 operates the yarn splicing arm portion 61b of the catching and guiding mechanism 61, and the yarn splicing device 60 operates the yarn splicing arm portion 61b of the catching guide mechanism 61 to separate the yarn feeding package P1 supported by the first peg 24a from the adapter 10 by the suction portion 61a. The first yarn end Y1 is captured, and the second yarn end Y2 is captured from the adapter 10 of the yarn supply package P1 supported by the second peg 24b. At this time, the yarn splicing device 60 operates the first peg 24a with the first rotation mechanism 62 and operates the second peg 24b with the second rotation mechanism 63 to rotate the yarn supply package P1. As a result, the yarn Y is pulled out from the yarn supply package P1 with a predetermined tension.

The moving device 70 moves each of the collecting device 40, the feeding device 50, and the yarn splicing device 60 to a working position relative to the peg 24. Furthermore, the moving device 70 moves the collection device 40 and the supply device 50 to a working position relative to the holding unit 32. As shown in FIG. 9, the moving device 70 includes a rotation support section 71 and a replacement unit drive section 72.

The rotation support section 71 supports the collection device 40, the supply device 50, and the yarn splicing device 60. The rotation support portion 71 is provided on the base 34 so as to be rotatable around a rotation axis extending in the vertical direction. The rotation support section 71 is arranged such that the recovery device 40, the supply device 50, and the yarn splicing device 60 are arranged facing three different directions when viewed from the direction of the rotation axis of the rotation support section 71. It supports the device 50 and the yarn splicing device 60.

The rotation support part 71 is stopped at a position where the yarn supply package P1 is acquired from the yarn supply package P1 and at a position where the collection device 40 supplies the yarn supply bobbin B1 to the holding unit 32.

Next, the operation of the package exchange device 7 will be explained.

[Package supply operation]
When the yarn feeding package P1 held by the holding unit 32 runs out, the package changing device 7 travels to the package replenishing device 6. When the package exchange device 7 is positioned in front of the package supply device 6, the holding unit 32 rotates the package support section 32b. Specifically, the holding unit 32 operates the drive section 32c to position the package support section 32b at the replenishment position (see FIG. 8(a)). The package supply device 6 uses a transfer device to transfer the yarn supply package P1 to the holding unit 32. As a result, the package support portion 32b of the holding unit 32 is supplied (supplied) with the yarn supply package P1. Note that when the collected yarn feeding bobbin B1 is held in the holding unit 32, the yarn feeding package P1 is supplied to the holding unit 32 after the collected yarn feeding bobbin B1 is transferred to the package supply device 6. .

[Package exchange operation]
The operation of exchanging the yarn supply package P1 by the package exchanging device 7 will be explained. In the following description, a mode in which a new yarn supply package P1 is attached to the first peg 24a will be described as an example. Note that it is determined whether or not the yarn supplying package P1 needs to be replaced based on the detection result of a sensor (not shown) that detects the remaining amount of yarn Y in the yarn supplying package P1.

When the package exchange device 7 travels in front of the creel stand 20 where the yarn supply package P1 needs to be exchanged, it moves the exchange unit 33 to a predetermined height position of the peg 24. The rotation device 35 of the package exchange device 7 operates the first drive mechanism 36 to rotate the first peg 24a and position the first peg 24a at the exchange position.

Furthermore, the moving device 70 positions the recovery device 40 at the working position. Specifically, the moving device 70 drives the exchange unit drive section 72 to rotate the rotation support section 71. Subsequently, the recovery device 40 recovers the yarn feeding bobbin B1 from the first peg 24a. The recovery device 40 uses the first support mechanism 41 to recover the yarn feeding bobbin B1.

Next, the moving device 70 positions the feeding device 50 in the working position. Subsequently, the supply device 50 attaches the yarn supply package P1 to the first peg 24a using the second support mechanism 51. When the yarn supply package P1 is attached to the first peg 24a, the rotation device 35 operates the first drive mechanism 36 to rotate the first peg 24a and position the first peg 24a at the supply position.

Next, the moving device 70 positions the yarn splicing device 60 at the working position. Subsequently, the yarn splicing device 60 captures the first yarn end Y1 from the adapter 10 of the yarn supply package P1 supported by the first peg 24a by the capture guide mechanism 61, and also captures the first yarn end Y1 from the adapter 10 supported by the second peg 24b. The second yarn end Y2 is captured from the adapter 10 of the yarn supply package P1. At this time, in the yarn splicing device 60, the first rotation mechanism 62 operates the first peg 24a, and the second rotation mechanism 63 operates the second peg 24b. The yarn splicing device 60 splices the captured first yarn end Y1 and second yarn end Y2. With the above steps, the replacement of the yarn feeding package P1 is completed.

In addition, after the yarn splicing between the first yarn end Y1 and the second yarn end Y2 is completed, the yarn splicing device 60 operates the first peg 24a using the first rotation mechanism 62, and operates the first peg 24a using the second rotation mechanism 63. It is preferable to rotate the yarn supply package P1 by operating the two pegs 24b and position the yarn supply package P1 at a predetermined position. The predetermined position is appropriately set depending on the inner shape of the bobbin cap BC attached to the yarn supply package P1. Depending on the shape of the bobbin cap BC, when the yarn supply package P1 rotates, the first package support member 41b of the recovery device 40 and the second package support member 51b of the supply device 50 may be inserted into the yarn supply bobbin B1. The first package support member 41b or the second package support member 51b may come into contact with the bobbin cap BC. Therefore, by rotating the yarn feeding package P1 to a predetermined position according to the inner shape of the bobbin cap BC, it is possible to avoid contact between the bobbin cap BC and the first package support member 41b or the second package support member 51b. can. Note that the mounting position of the bobbin cap BC corresponds to the mounting position of the adapter 10. Therefore, by detecting the position of the adapter 10, the position (orientation) of the bobbin cap BC can be determined.

As described above, in the false twisting system 1 according to the present embodiment, the creel stand 20 of the yarn feeding unit 5 has a plurality of pegs 24. The peg 24 has a yarn supply package support portion 25 that is inserted into the yarn supply bobbin B1 and supports the yarn supply package P1. The yarn feeding package support section 25 has a rotation mechanism 25c that rotates the yarn feeding package P1. Thereby, the peg 24 can rotate the yarn supply package P1 when the yarn Y is pulled out from the yarn supply package P1. Therefore, when the yarn splicing device 60 captures the yarn Y of the yarn supply package P1 and pulls out the yarn Y, it is possible to avoid applying excessive tension to the yarn Y. Therefore, the peg 24 can suppress the occurrence of yarn breakage during the yarn splicing operation.

In the peg 24 according to the present embodiment, the yarn supply package support section 25 extends along one direction and is parallel to each other, and the pair of packages that come into contact with the inner circumferential surface of the yarn supply bobbin B1. It has support members 25a and 25b. The rotation mechanism 25c rotates the pair of package support members 25a and 25b synchronously. In this configuration, the yarn feeding package P1 is supported at two points by the pair of package support members 25a and 25b. In this way, when the yarn feeding package P1 is supported at two points and the pair of package support members 25a and 25b are rotated synchronously, the yarn feeding Package P1 does not rotate once. Therefore, in the peg 24, the yarn feeding package P1 can be rotated little by little, so that the yarn Y can be paid out little by little. Therefore, the peg 24 can accurately pay out the yarn Y in accordance with the amount of yarn Y pulled out by the yarn splicing device 60.

In the peg 24 according to the present embodiment, the rotation mechanism 25c includes a driven pulley 25g provided on the package support member 25a, a drive pulley 25h provided on the package support member 25b, and a driven pulley 25g and a drive pulley 25h. It has a power transmission belt 25i that is stretched over. With this configuration, the package support member 25a and the package support member 25b can be rotated synchronously.

In the peg 24 according to the present embodiment, the rotation mechanism 25c includes a first wheel 25j that is provided on the package support member 25b and is rotationally driven by the yarn splicing device 60 that attaches the yarn supply package P1 to the peg 24. In this configuration, the first wheel 25j is rotationally driven by the first rotation mechanism 62 or the second rotation mechanism 63, so that the package support member 25a and the package support member 25b rotate synchronously. In this way, the individual pegs 24 provided in the creel stand 20 do not need to have a driving part, so costs can be reduced.

In the peg 24 according to the present embodiment, the package support member 25a and the package support member 25b are each provided with coating portions 25d and 25e made of resin at the portions that contact the inner circumferential surface of the yarn feeding bobbin B1. There is. In this configuration, since friction is generated between the coating parts 25d and 25e made of a resin such as rubber having frictional force and the inner circumferential surface of the yarn feeding bobbin B1, rotation of the pair of package support members 25a and 25b is prevented. The information can be reliably transmitted to the yarn supply package P1.

In the package exchange device 7 according to the present embodiment, the yarn splicing device 60 includes a first rotation mechanism 62 and a second rotation mechanism 63 that drive the first wheel 25j of the peg 24. Thereby, the yarn splicing device 60 can rotate the yarn supply package P1 supported by the peg 24 when pulling out the yarn Y from the yarn supply package P1.
