Japanese Patent Application Laid-Open No. 4-66479

In the synthetic yarn splicer described above, the yarn on the outer layer side of one package is spliced to the yarn on the inner layer side of another package. In this case, it is difficult to capture the ends of the yarn on the outer layer side and the inner layer side of the package, and as a result, it may be difficult to guide the yarn to the synthetic yarn splicer, for example.

One aspect of the present invention aims to provide an adapter and package replacement device that can easily capture the ends of the yarns on the outer and inner layers of a package.

The adapter according to one aspect of the present invention is an adapter that is attached to a package having a yarn made of synthetic fiber, and includes an attachment part that is synchronously rotatably attached to the bobbin of the package, a first holding part that is provided on the attachment part and holds the yarn end of the yarn on the outer layer side of the package, and a second holding part that is provided on the attachment part and holds the yarn end of the yarn on the inner layer side of the package.

By using this adapter, the yarn on the outer layer of the package can be held in advance by the first holding part, and the yarn on the inner layer of the package can be held in advance by the second holding part. This makes it possible to easily capture the yarn ends of the outer and inner layers of the package.

In an adapter according to one aspect of the present invention, the attachment portion has an annular outer ring portion that covers the outer peripheral surface of the bobbin with a gap, and the yarn on the inner layer side of the package may be wound around the outer ring portion. In this configuration, the outer ring portion can protect the outer peripheral surface of the bobbin without damaging it. In addition, since the yarn on the inner layer side of the package is wound around the outer ring portion, a sufficient length of yarn can be secured for, for example, piecing with a synthetic yarn splicer.

In an adapter according to one aspect of the present invention, the first holding section may have a first arm having a base end fixed to the attachment section, a first gripping tool provided at the tip end of the first arm for gripping the yarn end of the outer layer of the package, and a first yarn guide for hooking at least the yarn on the outer layer of the package. Such a first holding section can appropriately hold the yarn end of the outer layer of the package and can set the positional relationship of the yarn from the package to a predetermined position.

In the adapter according to one aspect of the present invention, the second holding part may have a second arm having a base end fixed to the attachment part, a second gripping tool provided at the tip side of the second arm for gripping the end of the yarn on the inner layer side of the package, and a second yarn guide for hooking the yarn on the inner layer side of the package. Such a second holding part can appropriately hold the end of the yarn on the inner layer side of the package, and can set the positional relationship of the yarn from the package to a predetermined position.

The package changing device according to one aspect of the present invention includes a synthetic yarn splicer that splices yarns from one package to which the adapter is attached and another package, and a yarn catching and guiding unit that catches the yarn end of the yarn held by the first holding unit of the adapter attached to the one package and guides it to the synthetic yarn splicer, and catches the yarn end of the yarn held by the second holding unit of the adapter attached to the other package and guides it to the synthetic yarn splicer.

In this package changing device, the adapter is attached to the first package and the second package, so that the yarn ends of the outer and inner layer yarns in the first package and the second package can be easily captured by the yarn capturing and guiding section. In addition, the yarn can be easily guided to the synthetic yarn splicer.

According to one aspect of the present invention, it is possible to provide an adapter and a package changing device that can easily capture the yarn ends of the outer and inner layer yarns in a package. According to one aspect of the present invention, it is possible to provide a package changing device that can easily guide a yarn to a synthetic yarn splicer.

The first lift unit 42c lifts and lowers the first slide unit 41a by driving the second recovery drive unit 42d. This causes the first slide unit 41a to swing. The second recovery drive unit 42d is, for example, a motor.

The recovery operation of the yarn supplying bobbin B1 by the recovery device 40 will be described. The recovery device 40 advances a part of the first slide portion 41a of the first support mechanism 41 by the first recovery drive mechanism 42 with respect to the peg 24 rotated by the rotation device 35, and positions the first package support member 41b in the hollow portion of the yarn supplying bobbin B1. At this time, the recovery device 40 swings the first slide portion 41a of the first support mechanism 41 downward by the first recovery drive mechanism 42, and tilts the first package support member 41b with respect to the horizontal direction. When the first package support member 41b is positioned in the hollow portion of the yarn supplying bobbin B1, the recovery device 40 swings the first slide portion 41a upward by the first recovery drive mechanism 42, and makes the first package support member 41b horizontal. As a result, the first package support member 41b comes into contact with the yarn supplying bobbin B1, lifting the yarn supplying bobbin B1 and separating the yarn supplying bobbin B1 from the package support members 25a and 25b. The recovery device 40 retracts a part of the first slide portion 41a of the first support mechanism 41 by the first recovery drive mechanism 42. In this way, the recovery device 40 recovers the yarn supplying bobbin B1 from the peg 24.

The supply device 50 supplies the yarn supply package P1 to the peg 24. As shown in FIG. 11, the supply device 50 has a second support mechanism 51 and a second supply drive mechanism 52. The second support mechanism 51 supports the yarn supply package P1. Furthermore, the second support mechanism 51 supplies the yarn supply package P1 by advancing and retreating from the peg 24. The second support mechanism 51 has a second slide portion 51a and a second package support member 51b.

The second slide portion 51a has a second linear guide 51c. A portion of the second slide portion 51a can move in a predetermined direction via the second linear guide 51c. The second package support member 51b supports the yarn supply package P1. The second package support member 51b is provided at the tip of the moving second slide portion 51a. The second package support member 51b extends along the extension direction of the second slide portion 51a.

The second supply drive mechanism 52 drives the second support mechanism 51. The second supply drive mechanism 52 has a second slide rail 52a, a first supply drive unit 52b, a second lift unit 52c, and a second supply drive unit 52d. The second slide rail 52a is connected to the second slide unit 51a. The second slide rail 52a reciprocates a part of the second slide unit 51a by driving the first supply drive unit 52b. The first supply drive unit 52b is, for example, an air cylinder. The second lift unit 52c is connected to the second slide unit 51a. The second lift unit 52c lifts and lowers the second slide unit 51a by driving the second supply drive unit 52d. This causes the second slide unit 51a to swing. The second supply drive unit 52d is, for example, a motor.

The following describes the acquisition operation in which the supply device 50 acquires the yarn supply package P1 from the holding unit 32. When the package exchange device 7 is moving, the supply device 50 acquires the yarn supply package P1 from the holding unit 32. When the exchange unit 33 stops at a predetermined height position relative to the holding unit 32, the supply device 50 advances a part of the second slide portion 51a of the second support mechanism 51 by the second supply drive mechanism 52 with respect to the yarn supply package P1 supported by the package support portion 32b of the holding unit 32, and positions the second package support member 51b in the hollow portion of the yarn supply package P1. At this time, the supply device 50 swings the second slide portion 51a of the second support mechanism 51 downward by the second supply drive mechanism 52, thereby tilting the second package support member 51b with respect to the horizontal direction. When the second package support member 51b is positioned in the hollow portion of the yarn supply package P1, the supply device 50 uses the second supply drive mechanism 52 to swing the second slide portion 51a upward to make the second package support member 51b horizontal. This brings the second package support member 51b into contact with the yarn supply package P1, lifting the yarn supply package P1 and separating the yarn supply package P1 from the package support portion 32b. The supply device 50 uses the second supply drive mechanism 52 to move back a portion of the second slide portion 51a of the second support mechanism 51. As described above, the supply device 50 obtains the yarn supply package P1 from the holding unit 32.

The supply operation of the supply device 50 to supply the yarn supply package P1 to the peg 24 will be described. The supply device 50 advances a part of the second slide portion 51a of the second support mechanism 51 by the second supply drive mechanism 52 with respect to the peg 24 from which the yarn supply bobbin B1 has been removed, and positions the package support members 25a, 25b of the peg 24 in the hollow portion of the yarn supply package P1. When the package support members 25a, 25b of the peg 24 are positioned in the hollow portion of the yarn supply package P1, the supply device 50 swings the second slide portion 51a downward by the second supply drive mechanism 52 to tilt the second package support member 51b with respect to the horizontal direction. As a result, the package support members 25a, 25b of the peg 24 come into contact with the yarn supply package P1, so that the yarn supply package P1 is supported by the peg 24, and the second package support member 51b and the yarn supply package P1 are separated from each other. The supply device 50 retracts a part of the second slide portion 51a of the second support mechanism 51 by the second supply drive mechanism 52. In this way, the supply device 50 attaches the yarn supply package P1 to the peg 24.

The yarn joining device 60 joins the yarn Y of the yarn supply package P1 supported by the first peg 24a to the yarn Y of the yarn supply package P1 supported by the second peg 24b. As shown in Figures 12, 13, and 14, the yarn joining device 60 includes a capture and guide mechanism 61, a first rotation mechanism (operation mechanism) 62, a second rotation mechanism (operation mechanism) 63, and a yarn joining mechanism 64.

The yarn joining device 60 is movable by a moving mechanism (not shown) in the opposing direction (Y direction) between the replacement unit 33 and the yarn supplying unit 5. The yarn joining device 60 moves between a standby position where the yarn joining device 60 is disposed within the base 34 and a yarn joining position where the yarn joining device 60 moves toward the yarn supplying unit 5 and advances outside the base 34.

The catching and guiding mechanism 61 catches the yarn Y of the yarn supply package P1 and guides the yarn Y to the yarn joining mechanism 64. The catching and guiding mechanism 61 catches the first yarn end Y1 of the yarn Y of the yarn supply package P1 supported by one peg 24 and the second yarn end Y2 of the yarn Y of the yarn supply package P1 supported by the other peg 24, and guides them to the yarn joining mechanism 64. The catching and guiding mechanism 61 has a suction portion 61a and a yarn joining arm portion 61b.

The suction section 61a sucks and captures the yarn Y. The suction section 61a has a suction pipe 61c, a suction nozzle 61d, and a hook section 61e. The suction nozzle 61d is provided at the tip of the suction pipe 61c. The suction nozzle 61d sucks the yarn Y. A negative pressure source (not shown) is connected to the suction pipe 61c. This generates a suction flow in the suction nozzle 61d. The base end side of the suction pipe 61c is connected to the yarn joining arm section 61b. The hook section 61e is provided at the tip of the suction pipe 61c and in a position facing away from the suction nozzle 61d. The hook section 61e engages the yarn Y intertwined by the yarn joining device 60. The yarn joining arm section 61b moves the suction section 61a. The yarn joining arm section 61b is configured to include a link mechanism and multiple motors. The yarn joining arm 61b is supported by a bracket 61f.

The first rotation mechanism 62 and the second rotation mechanism 63 each operate the peg 24 to rotate the yarn supply package P1. When the yarn Y is guided to the yarn joining mechanism 64 by the capture and guide mechanism 61, the first rotation mechanism 62 and the second rotation mechanism 63 each rotate the yarn supply package P1 to unwind the yarn Y from the yarn supply package P1.

The first rotation mechanism 62 operates the first peg 24a. The first rotation mechanism 62 has a first thread joining driver 62a, a first motor 62b, and a first thread joining arm 62c. The first thread joining driver 62a is rotatably supported by the first thread joining arm 62c. The first thread joining driver 62a is provided with a first driven pulley 62d. The first motor 62b is fixed to the first thread joining arm 62c. The first drive pulley 62e is connected to the output shaft of the first motor 62b. The first motor 62b drives the first drive pulley 62e to rotate around its axis. A first power transmission belt 62f is stretched between the first driven pulley 62d and the first drive pulley 62e. As a result, the first thread joining driver 62a rotates due to the rotation drive of the first motor 62b.

The second rotation mechanism 63 operates the second peg 24b. The second rotation mechanism 63 has a second thread joining driver 63a, a second motor 63b, and a second thread joining arm 63c. The second thread joining driver 63a is rotatably supported by the second thread joining arm 63c. The second thread joining driver 63a is provided with a second driven pulley 63d. The second motor 63b is fixed to the second thread joining arm 63c. The second drive pulley 63e is connected to the output shaft of the second motor 63b. The second motor 63b drives the second drive pulley 63e to rotate around its axis. A second power transmission belt 63f is stretched between the second driven pulley 63d and the second drive pulley 63e. As a result, the second thread joining driver 63a rotates due to the rotation drive of the second motor 63b.

The yarn joining mechanism 64 performs yarn joining. The yarn joining mechanism 64 has a splicer 66, a first guide mechanism 67, and a second guide mechanism 68.

The splicer 66 includes a yarn splicing unit 66a and a pair of clamping mechanisms 66b, 66c. The yarn splicing unit 66a intertwines the yarn Y of the yarn supply package P1 supported by the first peg 24a with the yarn Y of the yarn supply package P1 supported by the second peg 24b. The clamping mechanisms 66b, 66c are provided in positions that clamp the yarn splicing unit 66a. The clamping mechanisms 66b, 66c clamp the yarn Y that is inserted into the chamber of the yarn splicing unit 66a.

12 and 13, the first guide mechanism 67 engages and guides the yarn Y. The first guide mechanism 67 has a first hook 67a, a second hook 67b, and a third hook 67c. The first hook 67a, the second hook 67b, and the third hook 67c are arranged to be able to swing. The first hook 67a is provided with a potentiometer (not shown) for detecting the tension of the yarn Y. The yarn joining device 60 controls the operation of the first motor 62b of the first rotation mechanism 62 based on the detection result of the potentiometer. That is, the yarn joining device 60 adjusts the rotation amount (payout amount) of the yarn supply package P1 based on the detection result of the potentiometer, and pulls out the yarn Y from the yarn supply package P1 with a predetermined tension.

The second guide mechanism 68 engages and guides the yarn Y. The second guide mechanism 68 has a first hook 68a, a second hook 68b, and a third hook 68c. The first hook 68a, the second hook 68b, and the third hook 68c are arranged to be able to swing. The first hook 68a is provided with a potentiometer (not shown) that detects the tension of the yarn Y. The yarn joining device 60 controls the operation of the second motor 63b of the second rotation mechanism 63 based on the detection result of the potentiometer. That is, the yarn joining device 60 adjusts the rotation amount (payout amount) of the yarn supply package P1 based on the detection result of the potentiometer, and pulls out the yarn Y from the yarn supply package P1 with a predetermined tension.

The yarn joining operation of the yarn joining device 60 will be described. Specifically, an example will be described in which the yarn joining device 60 joins a first yarn end Y1 on the outer layer side of the yarn supply package P1 supported by the first peg 24a to a second yarn end Y2 on the inner layer side of the yarn supply package P1 supported by the second peg 24b.

When the yarn joining device 60 starts the yarn joining 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, and rotates the adapter 10 to a position where the suction part 61a can capture the first yarn end Y1 and the second yarn end Y2. Specifically, the first rotation mechanism 62 engages the first yarn joining driver 62a with the first wheel 25j of the first peg 24a and drives the first motor 62b to rotate the first yarn joining driver 62a. Similarly, the second rotation mechanism 63 engages the second yarn joining driver 63a with the first wheel 25j of the second peg 24b and drives the second motor 63b to rotate the second yarn joining driver 63a. When the first yarn splicing driver 62a and the second yarn splicing driver 63a rotate, the yarn supply 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 body (not shown) provided on the adapter 10 with a sensor (not shown), and controls the first motor 62b and the second motor 63b based on the detection result of the sensor to rotate the adapter 10 to a predetermined position.

When the yarn joining device 60 rotates the adapter 10, it activates the yarn joining arm 61b of the capture and guide mechanism 61, and the suction part 61a captures the first yarn end Y1 from the adapter 10 of the yarn supply package P1 supported by the first peg 24a, and captures the second yarn end Y2 from the adapter 10 of the yarn supply package P1 supported by the second peg 24b. At this time, the yarn joining device 60 operates the first peg 24a by the first rotation mechanism 62, and operates the second peg 24b by 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 yarn joining device 60 uses the suction unit 61a to hook the yarn Y having the first yarn end Y1 onto the first guide mechanism 67 and guide the yarn Y to the splicer 66, and hooks the yarn Y having the second yarn end Y2 onto the second guide mechanism 68 and guides the yarn Y to the splicer 66. After guiding the yarn Y to the splicer 66, the yarn joining device 60 causes the splicer 66 to perform a yarn joining operation. As a result, the yarn joining device 60 joins the first yarn end Y1 on the outer layer side of the yarn supply package P1 supported by the first peg 24a to the second yarn end Y2 on the inner layer side of the yarn supply package P1 supported by the second peg 24b.

The moving device 70 rotates and moves the collection device 40, the supply device 50, and the yarn joining device 60. The moving device 70 moves each of the collection device 40, the supply device 50, and the yarn joining device 60 to a working position relative to the peg 24. The moving device 70 also 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 has a rotation support unit 71 and a replacement unit drive unit 72.

The rotation support part 71 supports the recovery device 40, the supply device 50, and the yarn joining device 60. The rotation support part 71 is provided on the base 34 so as to be freely rotatable around a rotation axis extending in the vertical direction. The rotation support part 71 supports the recovery device 40, the supply device 50, and the yarn joining device 60 so that, as viewed from the direction of the rotation axis of the rotation support part 71, the recovery device 40, the supply device 50, and the yarn joining device 60 are arranged so that they each face three different directions.

The rotation support part 71 has a wheel (not shown). The wheel is a Geneva wheel that constitutes a Geneva mechanism. The replacement unit drive part 72 rotates the rotation support part 71. The replacement unit drive part 72 is a Geneva driver that constitutes a Geneva mechanism. The replacement unit drive part 72 rotates by the rotation drive of a motor (not shown). In the moving device 70, the rotation support part 71 rotates by the drive of the replacement unit drive part 72.

The moving device 70 stops the rotating support unit 71 at seven locations. The moving device 70 stops the rotating support unit 71 at a position where the recovery device 40 recovers the yarn supplying bobbin B1 from the first peg 24a, a position where the recovery device 40 recovers the yarn supplying bobbin B1 from the second peg 24b, a position where the supplying device 50 supplies the yarn supplying package P1 to the first peg 24a, a position where the supplying device 50 supplies the yarn supplying package P1 to the second peg 24b, a position where the yarn joining device 60 performs yarn joining, a position where the supplying device 50 acquires the yarn supplying package P1 from the holding unit 32, and a position where the recovery device 40 supplies the yarn supplying bobbin B1 to the holding unit 32.

Next, we will explain the adapter 10 in detail.

As shown in at least one of Figures 15, 16, 17, and 18, the attachment portion 11 of the adapter 10 has an outer ring portion 11x and an inner ring portion 11y. The outer ring portion 11x and the inner ring portion 11y are annular, specifically cylindrical. The outer ring portion 11x covers the outer peripheral surface at the end of the yarn supplying bobbin B1 with a gap. The yarn Y of the inner layer side of the yarn supplying package (package) P1, which has the yarn Y made of synthetic fiber, is wound around the outer ring portion 11x. The inner ring portion 11y is arranged coaxially on the radial inside of the outer ring portion 11x. The inner ring portion 11y is connected to the end of the outer ring portion 11x. The inner ring portion 11y is fitted in contact with the inner peripheral surface of the yarn supplying bobbin B1.

The first arm 12a of the first holding portion 12 of the adapter 10 extends from the outer peripheral surface of the outer ring portion 11x so as to protrude radially outward. The tip of the first arm 12a is configured to be bent inward in the axial direction of the yarn supply package P1. The first gripping tool 12b is fixed to the tip of the first arm 12a. The first gripping tool 12b has a spring. The first gripping tool 12b holds the first yarn end Y1 of the outer layer yarn Y of the yarn supply package P1 by inserting the first yarn end Y1 into the first gripping tool 12b with the elastic force of the spring. The first gripping tool 12b can utilize a spring tensor structure.

The first yarn guide 12c of the first holding section 12 hooks the yarn Y on the outer layer side and the yarn Y on the inner layer side of the yarn supply package P1. The first yarn guide 12c guides the yarn Y on the outer layer side of the yarn supply package P1 so that its first yarn end Y1 faces the first gripper 12b. The first yarn guide 12c guides the yarn Y on the inner layer side of the yarn supply package P1 so that its second yarn end Y2 faces the second yarn guide 13c. The first yarn guide 12c is composed of a linear member such as an appropriately bent wire. The first yarn guide 12c is provided at the center of the extension direction of the first arm 12a. The first yarn guide 12c extends from the center in a direction intersecting the extension direction of the first arm 12a, and then extends so as to bend toward the tip side of the first arm 12a. The outer layer yarn Y of the yarn supply package P1 is hooked to the tip side of the first yarn guide 12c, and the inner layer yarn Y of the yarn supply package P1 is hooked to the base end side of the first yarn guide 12c (see Figure 3).

The second arm 13a of the second holding portion 13 of the adapter 10 is extended so as to protrude radially outward from the 180° opposite side of the first arm 12a on the outer peripheral surface of the outer ring portion 11x. The tip of the second arm 13a is configured to be bent inward in the axial direction of the yarn supply package P1. The second gripping tool 13b is fixed to the tip of the second arm 13a. The second gripping tool 13b has a spring. The second gripping tool 13b inserts the second yarn end Y2 of the inner layer yarn Y of the yarn supply package P1, and grips the second yarn end Y2 with the elastic force of the spring. The second gripping tool 13b can utilize the structure of a spring tensor.

The second yarn guide 13c of the second holding portion 13 hooks the yarn Y on the inner layer side of the yarn supply package P1. The second yarn guide 13c guides the yarn Y on the inner layer side of the yarn supply package P1 so that its second yarn end Y2 is directed toward the second gripper 13b. The second yarn guide 13c is composed of a linear member such as an appropriately bent wire. The second yarn guide 13c extends from the center in a direction intersecting the extension direction of the second arm 13a, and then extends so as to bend toward the tip side of the second arm 13a. The inner layer yarn Y of the yarn supply package P1 is hooked to the tip side of the second yarn guide 13c (see Figure 3).

As described above, the splicer (synthetic yarn splicer) 66 shown in Figures 12 to 14 splices yarns from one yarn supply package (one package) P1 and another yarn supply package (another package) P1. An adapter 10 is attached to each of the one yarn supply package P1 and the other yarn supply package P1. The capture and guide mechanism (yarn capture and guide section) 61 captures the first yarn end Y1 of the yarn Y held by the first holding section 12 of the adapter 10 attached to the one yarn supply package P1 and guides it to the splicer 66, and also captures the second yarn end Y2 of the yarn Y held by the second holding section 13 of the adapter 10 attached to the other yarn supply package P1 and guides it to the splicer 66.

As described above, in this embodiment, by using the adapter 10, the first yarn end Y1 of the yarn Y on the outer layer side of the yarn supply package P1 can be held in advance by the first holding portion 12, and the second yarn end Y2 of the yarn Y on the inner layer side of the yarn supply package P1 can be held in advance by the second holding portion 13. Therefore, it is possible to easily capture the first yarn end Y1 and the second yarn end Y2 on the outer layer side and the inner layer side of the yarn supply package P1.

In the adapter 10, the attachment portion 11 has an outer ring portion 11x that covers the outer peripheral surface of the yarn supplying bobbin B1 with a gap. The yarn Y on the inner layer side of the yarn supplying package P1 is wound around the outer ring portion 11x. In this configuration, the outer ring portion 11x can protect the outer peripheral surface of the yarn supplying bobbin B1 without damaging it. In addition, since the yarn Y on the inner layer side of the yarn supplying package P1 is wound around the outer ring portion 11x, a sufficient length of the yarn Y can be secured for, for example, splicing with a splicer 66.

In the adapter 10, the first holding section 12 has a first arm 12a, a first gripper 12b, and a first yarn guide 12c. The first holding section 12 configured in this way can properly hold the first yarn end Y1 of the outer layer yarn Y in the yarn supply package P1, and can set the positional relationship of the yarn Y from the yarn supply package P1 to the second yarn end Y2 in a predetermined position.

In the adapter 10, the second holding section 13 has a second arm 13a, a second gripper 13b, and a second yarn guide 13c. The second holding section 13 configured in this way can properly hold the second yarn end Y2 of the inner layer yarn Y in the yarn supply package P1, and can set the positional relationship of the yarn Y from the yarn supply package P1 to the second yarn end Y2 at a predetermined position.

In the package exchange device 7, the adapter 10 is attached to the first yarn supply package P1 and the second yarn end Y2 of the yarn Y in the first yarn supply package P1 and the second yarn supply package P1 can be easily captured by the capturing and guiding mechanism 61. In addition, the yarn Y can be easily guided to the splicer 66.
