Description

Package replacing device

Technical Field

One aspect of the present invention relates to a package replacement device.

Background

As a conventional package exchange device, for example, a device described in patent document 1 (japanese patent application laid-open No. 4-66479) is known. The package replacement device described in patent document 1 is a device for performing replacement of a package on a bobbin (Peg) provided in a creel, and includes a traveling device for traveling along the creel, a setting device for performing package replacement on the bobbin, and a yarn splicing device for performing splicing between yarns of two packages. The setting device and the joint device are disposed on a base of the travel device.

In the conventional package changing device, 2 setting devices are arranged in a row in the traveling direction of the traveling device. In a conventional package replacing device, an old package is collected from each bobbin by one setting device, and a new package is mounted on each bobbin by another setting device. Therefore, in the conventional package replacement device, after one setting device is located at a position before the subject bobbin and the old package is collected from the bobbin, the traveling device is caused to travel and the other setting device is located at a position before the subject bobbin and a new package is mounted on the bobbin. In this way, in the conventional package replacement device, the setting device needs to be moved by the traveling of the traveling device at the time of replacement of the package, which is not efficient.

Disclosure of Invention

An object of one aspect of the present invention is to provide a package replacement device that improves the efficiency of the package replacement operation.

A package exchange device according to an aspect of the present invention is a package exchange device for mounting a yarn supply package in which a synthetic fiber yarn made of synthetic fibers is wound around a yarn supply bobbin, the bobbin being provided on a creel arranged in one direction, the package exchange device including: a recovery device for recovering the yarn supplying bobbin from the shuttle peg; a supply device for mounting a yarn supply package on the bobbin; a piecing device for piecing the yarn of the yarn supply package mounted on the supply device with the yarn of the yarn supply package held by another bobbin; a moving device configured with the recovery device, the supply device and the joint device, and moving the recovery device, the supply device and the joint device to operation positions for operating the shuttle peg; and a traveling unit for moving the base supporting the moving device along the arrangement direction of the creels, wherein the moving device comprises: a rotation support portion which supports the recovery device, the supply device, and the joint device, and is provided to be rotatable about a rotation axis; and a replacement unit drive unit that rotationally drives the rotation support unit.

A package changing device according to an aspect of the present invention includes a moving device that moves the collecting device, the supplying device, and the splicing device to respective operation positions for operating the bobbin. The moving device rotates the recovery device, the supply device, and the joint device around the rotation axis, thereby positioning each device at the working position. In this way, in the package changing device, even if the position of each device is moved without causing the traveling unit to travel, each device can be positioned at the working position. Therefore, in the package exchanging device, the work efficiency can be improved for exchanging the yarn feeding package.

In one embodiment, the yarn feeding device may include a holding device that holds a plurality of yarn feeding packages, the moving device may position the feeding device at an operation position where the moving device operates the holding device, and the feeding device may acquire the yarn feeding packages from the holding device. In this configuration, since the yarn feeding package is held by the holding device, the yarn feeding package can be obtained from the holding device. Therefore, in the package replacement device, it is not necessary to go to the storage position to take out the yarn supply package each time the yarn supply package is replaced. Therefore, in the package exchanging device, the work efficiency can be improved for exchanging the yarn feeding package.

In one embodiment, the bobbin may have a rotation mechanism for rotating the yarn supply package, and the yarn splicing device may have an operation mechanism for driving the rotation mechanism of the bobbin. In this configuration, when the yarn splicing device pulls out the yarn from the yarn supply package, the yarn supply package supported by the bobbin can be rotated. Therefore, when the yarn splicing device catches the yarn of the yarn supply package and pulls out the yarn, excessive tension can be prevented from being applied to the yarn. Thus, in the package changing device, the occurrence of yarn breakage during the yarn splicing operation can be suppressed. As a result, in the package replacement device, the work efficiency can be improved for the replacement of the yarn supply package.

In one embodiment, after the yarn supply package is mounted on the bobbin by the supply device, the yarn splicing device may catch the first yarn end of one yarn supply package and the second yarn end of the other yarn supply package to perform yarn splicing. For example, in a configuration in which the yarn supply package is mounted on the bobbin after the yarn splicing operation is performed, the entangled yarn may be loosened due to tension or the like applied to the yarn during the mounting operation of the yarn supply package. In this case, the replacement of the yarn supply package ends up failing, and the operation must be performed again. In the package changing device, the yarn supplying package is mounted on the bobbin by the supplying device, and then the yarn splicing device performs yarn splicing. Therefore, in the package changer, the yarn entangled with the package during the mounting operation of the yarn supply package can be prevented from being loosened. As a result, in the package replacement device, the work efficiency can be improved for the replacement of the yarn supply package.

According to one aspect of the present invention, the efficiency of the operation can be improved in connection with the package replacement.

The first driving mechanism 36 rotates the first bobbin 24a of the creel 20. The first drive mechanism 36 has a first rotary actuator 36a and a first rotary arm 36 b. The first rotary drive 36a rotates the second wheel 26e of the first bobbin 24 a. The first rotary driver 36a is a geneva type intermittent driver constituting a geneva type intermittent mechanism. The first rotary actuator 36a is rotated by a motor (not shown) for rotation. The first rotary arm 36b supports the first rotary actuator 36 a. The first rotation arm portion 36b is provided swingably in the horizontal direction. The first rotation arm 36b is driven by a motor or a cylinder (not shown), for example.

The second driving mechanism 37 rotates the second bobbin 24b of the creel 20. The second drive mechanism 37 has a second pivot driver 37a and a second pivot arm 37 b. The second rotary drive 37a rotates the second wheel 26e of the second bobbin 24 b. The second rotary driver 37a is a geneva type intermittent driver constituting a geneva type intermittent mechanism. The second pivot actuator 37a is rotated by rotational driving of a motor (not shown). The second turning arm portion 37b supports the second turning actuator 37 a. The second turning arm portion 37b is provided to be swingable in the horizontal direction. The second pivot arm portion 37b is driven by a motor or an air cylinder (not shown), for example.

When the yarn supply package P1 is attached to the bobbin 24, the rotating device 35 rotates the bobbin 24 to change the orientation of the bobbin 24. The turning device 35 operates a first drive mechanism 36 or a second drive mechanism 37 corresponding to the target bobbin 24. For example, when the first driving mechanism 36 is operated, the turning device 35 swings the first turning arm 36b, and the first rotary actuator 36a engages with the second sheave 26e of the first bobbin 24 a. When the first rotary driver 36a is engaged with the second wheel 26e, the rotating device 35 rotates the first rotary driver 36a in one direction. When the second wheel 26e rotates, the rotation transmitting member 26b rotates in the bobbin 24. Thereby, the bobbin 24 rotates, and the leading end portions of the

package support members

25a and 25b face the replacing unit 33.

The recovery device 40 recovers the yarn supplying bobbin B1 to which the splicer 10 is attached from the bobbin 24. As shown in fig. 10, the recovery device 40 includes a first support mechanism 41 and a first recovery drive mechanism 42. The first supporting mechanism 41 supports the yarn supplying bobbin B1. The first support mechanism 41 moves forward and backward with respect to the bobbin 24, thereby collecting the yarn supplying bobbin B1. The first support mechanism 41 includes a first slide portion 41a and a first roll support member 41 b.

The first sliding portion 41a has a first linear guide 41 c. A part of the first sliding portion 41a is movable in a predetermined direction via the first linear guide 41 c.

The first elevating portion 42c is connected to the first sliding portion 41 a. The first lifting/lowering section 42c lifts and lowers the first sliding section 41a by driving the second collection driving section 42 d. Thereby, the first sliding portion 41a swings. The second recovery driving unit 42d is, for example, a motor.

Next, the collecting operation of the yarn supplying bobbin B1 by the collecting device 40 will be described. In the recovery device 40, the first recovery driving mechanism 42 moves a part of the first sliding portion 41a of the first support mechanism 41 forward relative to the bobbin 24 rotated by the rotating device 35, and the first winding support member 41B is positioned in the hollow portion of the yarn supplying bobbin B1. In this case, in the recovery device 40, the first sliding portion 41a of the first support mechanism 41 is swung downward by the first recovery drive mechanism 42, and the first reel support member 41b is tilted with respect to the horizontal direction. In the recovery device 40, when the first package support member 41B is positioned in the hollow portion of the yarn supplying bobbin B1, the first recovery driving mechanism 42 swings the first sliding portion 41a upward to level the first package support member 41B. Thereby, the first package support member 41B contacts the yarn supplying bobbin B1, the yarn supplying bobbin B1 is lifted, and the yarn supplying bobbin B1 is separated from the package support members 25a and 25B. The recovery device 40 retracts a part of the first sliding portion 41a of the first support mechanism 41 by the first recovery drive mechanism 42. With this, the recovery device 40 recovers the yarn supplying bobbin B1 from the bobbin 24.

The supply device 50 supplies the yarn supply package P1 to the bobbin 24. As shown in fig. 11, the supply device 50 includes a second support mechanism 51 and a second supply drive mechanism 52. The second support mechanism 51 supports the yarn supply package P1. The second support mechanism 51 moves forward and backward with respect to the bobbin 24, thereby supplying the yarn supply package P1. The second support mechanism 51 includes a second slide portion 51a and a second package support member 51 b.

The second slide portion 51a has a second linear guide 51 c. A part of the second sliding portion 51a is movable in a predetermined direction via the second linear guide 51 c. The second package support member 51b supports the yarn supply package P1. The second package supporting member 51b is provided at the distal end of the moving second sliding portion 51 a. The second package support member 51b extends along the extending direction of the second sliding portion 51 a.

The second supply drive mechanism 52 drives the second support mechanism 51. The second supply drive mechanism 52 includes a second slide rail 52a, a first supply drive unit 52b, a second elevating unit 52c, and a second supply drive unit 52 d. The second slide rail 52a is connected to the second slide portion 51 a. The second slide rail 52a reciprocates a part of the second slide portion 51a by the driving of the first supply driving portion 52 b. The first supply driving unit 52b is, for example, an air cylinder. The second lifting portion 52c is connected to the second slide portion 51 a. The second raising/lowering portion 52c raises/lowers the second slide portion 51a by the driving of the second supply driving portion 52 d. Thereby, the second slide portion 51a swings. The second supply driving unit 52d is, for example, a motor.

The operation of the supply device 50 to obtain the yarn supply package P1 from the holding unit 32 will be described. The supply device 50 acquires the yarn supply package P1 from the holding unit 32 while the package replacement device 7 is moving. In the supply device 50, when the replacing unit 33 is stopped at the predetermined height position with respect to the holding unit 32, the second supply driving mechanism 52 moves a part of the second sliding portion 51a of the second supporting mechanism 51 forward with respect to the yarn supply package P1 supported by the package supporting portion 32b of the holding unit 32, thereby positioning the second package supporting member 51b in the hollow portion of the yarn supply package P1. At this time, the supply device 50 causes the second sliding portion 51a of the second support mechanism 51 to swing downward by the second supply drive mechanism 52, thereby tilting the second package support member 51b with respect to the horizontal direction. In the supply device 50, when the second package support member 51b is positioned in the hollow portion of the yarn supply package P1, the second slide portion 51a is swung upward by the second supply driving mechanism 52 to horizontally position the second package support member 51 b. Thereby, the second package support member 51b contacts the yarn supply package P1, the yarn supply package P1 is lifted, and the yarn supply package P1 is separated from the package support member 32 b. 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. As described above, the supply device 50 obtains the yarn supply package P1 from the holding unit 32.

Next, a feeding operation of the feeding device 50 for feeding the yarn supply package P1 to the bobbin 24 will be described. In the supply device 50, the second supply driving mechanism 52 moves a part of the second slide portion 51a of the second support mechanism 51 forward relative to the bobbin 24 from which the yarn supplying bobbin B1 has been removed, thereby positioning the package support members 25a and 25B of the bobbin 24 in the hollow portion of the yarn supplying package P1. In the supply device 50, when the

package support members

25a and 25b of the bobbin 24 are positioned in the hollow portion of the yarn supply package P1, the second slide portion 51a is swung downward by the second supply driving mechanism 52, and the second package support member 51b is inclined with respect to the horizontal direction. Thus, the

package support members

25a and 25b of the bobbin 24 contact the yarn supply package P1, the yarn supply package P1 is supported by the bobbin 24, and the second package support member 51b is separated from the yarn supply package P1. 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. As described above, the supply device 50 mounts the yarn supply package P1 to the bobbin 24.

The yarn splicing device 60 splices the yarn Y of the yarn supply package P1 supported by the first bobbin 24a and the yarn Y of the yarn supply package P1 supported by the second bobbin 24 b.

The suction nozzle 61d is provided at the tip of the suction pipe 61 c. The suction nozzle 61d sucks the yarn Y. A negative pressure source (not shown) is connected to the suction pipe 61 c. Thereby, suction flow is generated in the suction nozzle 61 d. The proximal end side of the suction pipe 61c is connected to the joint arm portion 61 b. The hook 61e is provided at the tip of the suction pipe 61c and is opposite to the suction nozzle 61 d. The hook 61e locks the yarn Y entangled by the yarn splicing device 60. The joint arm portion 61b moves the suction portion 61 a. The joint arm portion 61b includes a link mechanism and a plurality of motors. The joint arm portion 61b is supported by the bracket 61 f.

The first rotating mechanism 62 and the second rotating mechanism 63 operate the bobbin 24 to rotate the yarn supply package P1. The first and second

rotating mechanisms

62 and 63 respectively rotate the yarn supply package P1 to sequentially discharge the yarn Y from the yarn supply package P1 when the yarn Y is guided to the yarn splicing mechanism 64 by the catching and guiding mechanism 61.

The first rotating mechanism 62 operates the first bobbin 24 a. The first rotating mechanism 62 has a first joint driver 62a, a first motor 62b, and a first joint arm 62 c. The first joint driver 62a is rotatably supported by the first joint arm 62 c. A first driven pulley 62d is provided on the first joint driver 62 a. The first motor 62b is fixed to the first joint arm portion 62 c. A first drive pulley 62e is connected to an output shaft of the first motor 62 b. The first motor 62b rotationally drives the first drive pulley 62e about the shaft. A first power transmission belt 62f is stretched over the first driven pulley 62d and the first drive pulley 62 e. Thereby, the first joint driver 62a is rotated by the rotational driving of the first motor 62 b.

The second rotating mechanism 63 operates the second bobbin 24 b. The second rotation mechanism 63 has a second joint driver 63a, a second motor 63b, and a second joint arm portion 63 c.

The second motor 63b is fixed to the second joint arm portion 63 c. A second drive pulley 63e is connected to an output shaft of the second motor 63 b. The second motor 63b rotationally drives the second drive pulley 63e about the shaft. A second power transmission belt 63f is provided over the second driven pulley 63d and the second drive pulley 63 e. Thereby, the second joint driver 63a is rotated by the rotational driving of the second motor 63 b.

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

The splicer 66 includes a joint portion 66a and a pair of clamping

mechanisms

66b and 66 c. The joint 66a crossovers the yarn Y of the yarn supply package P1 supported by the first bobbin 24a and the yarn Y of the yarn supply package P1 supported by the second bobbin 24 b. The clamping

mechanisms

66b, 66c are provided at positions where the joint portion 66a is clamped. The gripping

mechanisms

66b, 66c grip the yarn Y inserted in the chamber of the socket portion 66 a.

As shown in fig. 12 and 13, the first guide mechanism 67 guides the yarn Y by locking the yarn Y. The first guide mechanism 67 has a first hook 67a, a second hook 67b, and a third hook 67 c. The first hook 67a, the second hook 67b, and the third hook 67c are provided to be swingable. A potentiometer (not shown) for detecting the tension of the yarn Y is provided to the first hook 67 a. The joint 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 splicing device 60 adjusts the rotation amount (the discharge 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 locks and guides the yarn Y. The second guide mechanism 68 has a first hook 68a, a second hook 68b, and a third hook 68 c. The first hook 68a, the second hook 68b, and the third hook 68c are provided to be swingable. A potentiometer (not shown) for detecting the tension of the yarn Y is provided on the first hook 68 a. The joint 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 splicing device 60 adjusts the rotation amount (the discharge 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 joint operation of the joint device 60 will be described. Specifically, a case where the yarn splicing device 60 splices the first yarn end Y1 on the outer layer side of the yarn supplying package P1 supported by the first bobbin 24a and the second yarn end Y2 on the inner layer side of the yarn supplying package P1 supported by the second bobbin 24b will be described as an example.

When the yarn splicing operation is started, as shown in fig. 14, the yarn splicing device 60 operates the first bobbin 24a by the first rotating mechanism 62 and operates the second bobbin 24b by the second rotating mechanism 63 to rotate the splicer 10 to a position where the first yarn end Y1 and the second yarn end Y2 can be caught by the suction portion 61 a. Specifically, in the first rotating mechanism 62, the first joint driver 62a is engaged with the first wheel 25j of the first bobbin 24a, and the first motor 62b is driven to rotate the first joint driver 62 a. Similarly, in the second rotating mechanism 63, the second joint driver 63a is engaged with the first wheel 25j of the second bobbin 24b, and the second motor 63b is driven to rotate the second joint driver 63 a. When the first joint driver 62a and the second joint driver 63a rotate, the yarn supply package P1 supported by each of the first bobbin 24a and the second bobbin 24b rotates, and the splicer 10 rotates along with this rotation. The joint device 60 detects a detection body (not shown) provided in the adapter 10 by 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 splicer device 60 rotates the splicer 10, the splice arm portion 61b of the catching guide mechanism 61 is operated, and the suction portion 61a catches the first yarn end Y1 from the splicer 10 of the yarn supply package P1 supported by the first bobbin 24a and catches the second yarn end Y2 from the splicer 10 of the yarn supply package P1 supported by the second bobbin 24 b. At this time, the yarn splicing device 60 rotates the yarn supply package P1 by operating the first rotation mechanism 62 on the first bobbin 24a and operating the second rotation mechanism 63 on the second bobbin 24 b. Thereby, the yarn Y is drawn out from the yarn supply package P1 with a predetermined tension.

The yarn Y having the first yarn end Y1 is hooked by the suction portion 61a to the first guide mechanism 67 and guided to the splicer 66, and the yarn Y having the second yarn end Y2 is hooked by the second guide mechanism 68 and guided to the splicer 66. The yarn splicing device 60 is configured to cause the splicer 66 to perform a splicing operation when the yarn Y is guided to the splicer 66. Thus, the yarn splicing device 60 splices the first yarn end Y1 on the outer layer side of the yarn supply package P1 supported by the first bobbin 24a and the second yarn end Y2 on the inner layer side of the yarn supply package P1 supported by the second bobbin 24 b.

The moving device 70 rotates and moves the recovery device 40, the supply device 50, and the joint device 60. The moving device 70 moves the recovery device 40, the supply device 50, and the joint device 60 to the respective working positions for working the bobbin 24. The moving device 70 moves the recovery device 40 and the supply device 50 to the working position where the work is performed on the holding unit 32. As shown in fig. 9, the moving device 70 includes a rotation support portion 71 and a replacement unit driving portion 72.

The rotation support portion 71 supports the recovery device 40, the supply device 50, and the joint device 60. The rotation support portion 71 is provided in the base 34 to be rotatable about a rotation axis extending in the vertical direction. The rotation support portion 71 supports the recovery device 40, the supply device 50, and the joint device 60 such that the recovery device 40, the supply device 50, and the joint device 60 are arranged in 3 different directions, respectively, as viewed from the rotation axis direction of the rotation support portion 71.

The rotation support portion 71 has wheels (not shown). The wheel is a Ma intermittent wheel which forms a Ma intermittent mechanism. The replacement unit driving portion 72 rotates the rotation support portion 71. The replacement unit driving section 72 is a geneva drive constituting a geneva mechanism. The replacement unit driving unit 72 is rotated by rotational driving of a motor (not shown). The moving device 70 rotates the rotation support portion 71 by being driven by the replacement unit driving portion 72.

The moving device 70 stops the rotation support portion 71 at 7 places. The moving device 70 stops the rotation support portion 71 at: the recovery device 40 recovers the position of the yarn supplying bobbin B1 from the first bobbin 24 a; the position where the recovering device 40 recovers the yarn supplying bobbin B1 from the second bobbin 24B; a position at which the supply device 50 supplies the yarn supply package P1 to the first bobbin 24 a; a position at which the supply device 50 supplies the yarn supply package P1 to the second bobbin 24 b; the position where the joint device 60 performs the joint; the supply device 50 acquires the position of the yarn supply 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.

Specifically, as shown in fig. 15A, the moving device 70 stops the rotation support portion 71 at a first stop position SP1 where the recovery device 40 is disposed to face the first bobbin 24 a. As shown in fig. 15B, the moving device 70 stops the rotation support portion 71 at a second stop position SP2 where the recovery device 40 is disposed to face the second bobbin 24B. As shown in fig. 16A, the moving device 70 stops the rotation support portion 71 at a third stop position SP3 where the supply device 50 is disposed to face the first bobbin 24 a.

As shown in fig. 16B, the moving device 70 stops the rotation support portion 71 at a fourth stop position SP4 where the supply device 50 is disposed to face the second bobbin 24B. As shown in fig. 17A, the moving device 70 stops the rotation support portion 71 at a fifth stop position SP5 where the joint device 60 is disposed to face the first bobbin 24a and the second bobbin 24 b. As shown in fig. 17B, the moving device 70 stops the rotation support portion 71 at a sixth stop position SP6 where the supply device 50 is disposed to face the package support portion 32B of the holding unit 32. As shown in fig. 17C, the moving device 70 stops the rotation support portion 71 at a seventh stop position SP7 where the recovery device 40 and the package support portion 32b of the holding unit 32 are arranged to face each other.

Next, the operation of the package exchanging apparatus 7 will be described.

The package supply operation is performed such that when the yarn supply package P1 held by the holding unit 32 is used up, the package exchange device 7 travels to the package supply device 6. When the package replacement device 7 is positioned in front of the package supply device 6, the holding unit 32 rotates the package support portion 32 b. Specifically, the holding unit 32 operates the driving unit 32c to position the package support portion 32b at the supply position (see fig. 8A). The package supply device 6 transfers the yarn supply package P1 to the holding unit 32 by the transfer device. Thereby, the yarn supply package P1 is supplied (replenished) to the package support portion 32b of the holding unit 32. When the collected yarn supplying bobbin B1 is held in the holding unit 32, the collected yarn supplying bobbin B1 is transferred to the package supply device 6, and then the yarn supplying package P1 is supplied to the holding unit 32.

The package replacement operation describes the replacement operation of the yarn supply package P1 by the package replacement device 7. In the following description, a mode of attaching the new yarn supply package P1 to the first bobbin 24a will be described as an example. The yarn supply package P1 determines whether replacement is necessary based on the detection result of a sensor (not shown) that detects the remaining amount of the yarn Y in the yarn supply package P1.

When the package replacement device 7 runs to a position before the creel 20, at which the yarn supply package P1 needs to be replaced, the replacement unit 33 is moved to a predetermined height position of the bobbin 24. The turning device 35 of the package replacement device 7 operates the first driving mechanism 36 to turn the first bobbin 24a so that the first bobbin 24a is positioned at the replacement position.

The moving device 70 stops the rotation support portion 71 at the first stop position SP1 (see fig. 15A) and positions the recovery device 40 at the working position. Specifically, the moving device 70 drives the replacement unit driving unit 72 to rotate the rotation support portion 71. Subsequently, the recovery device 40 recovers the yarn supplying bobbin B1 from the first bobbin 24 a. The recovery device 40 recovers the yarn supplying bobbin B1 by the first supporting mechanism 41.

Next, the moving device 70 stops the rotation support portion 71 at the third stop position SP3 (see fig. 16A) and positions the supply device 50 at the working position. Next, the supply device 50 mounts the yarn supply package P1 on the first bobbin 24a via the second support mechanism 51. When the yarn supply package P1 is mounted on the first bobbin 24a, the rotating device 35 operates the first driving mechanism 36 to rotate the first bobbin 24a and position the first bobbin 24a at the supply position.

Next, the moving device 70 stops the rotation support portion 71 at the fifth stop position SP5 (see fig. 17A) and positions the joint device 60 at the working position. Next, the yarn splicing device 60 captures the first yarn end Y1 from the splicer 10 of the yarn supply package P1 supported by the first bobbin 24a and captures the second yarn end Y2 from the splicer 10 of the yarn supply package P1 supported by the second bobbin 24b by the capture guide mechanism 61. At this time, the joint device 60 operates the first bobbin 24a by the first rotating mechanism 62 and operates the second bobbin 24b by the second rotating mechanism 63. The yarn splicing device 60 splices the captured first yarn end Y1 and second yarn end Y2. As a result, the replacement of the yarn supply package P1 is completed.

Further, after the yarn splicing between the first yarn end Y1 and the second yarn end Y2 is completed, the yarn splicing device 60 preferably rotates the yarn supply package P1 by operating the first bobbin 24a by the first rotation mechanism 62 and the second bobbin 24b by the second rotation mechanism 63, so that the yarn supply package P1 is positioned at a predetermined position. The predetermined position is set as appropriate in accordance with the inner shape of the bobbin cap BC attached to the yarn supply package P1. Depending on the shape of the cap BC, when the yarn supply package P1 is rotated, the first package support member 41B of the collecting device 40 and the second package support member 51B of the supplying device 50 may come into contact with the cap BC when the first package support member 41B or the second package support member 51B is inserted into the yarn supply bobbin B1. Therefore, by rotating the yarn supply package P1 to a predetermined position in accordance with the inner shape of the bobbin cap BC, contact between the bobbin cap BC and the first package support member 41b or the second package support member 51b can be avoided. Further, 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 cartridge cap BC can be grasped.

As described above, the package exchanging device 7 according to the present embodiment includes the moving device 70, and the moving device 70 moves the collecting device 40, the supplying device 50, and the splicing device 60 to the operation positions for operating the bobbin 24. The moving device 70 rotates the recovery device 40, the supply device 50, and the joint device 60 about a rotation axis extending in the vertical direction, thereby positioning each device at a working position. In this way, in the package exchanging device 7, even if the position of each device is moved without causing the traveling carriage 30 to travel, each device can be positioned at the working position. Thus, in the package replacement device 7, the work efficiency can be improved with respect to the replacement of the yarn supply package P1.

The package replacement device 7 according to the present embodiment includes a holding unit 32 that holds a plurality of yarn supply packages P1. The moving device 70 positions the recovery device 40 or the supply device 50 at a working position where work is performed on the holding unit 32. The supply device 50 located at the working position obtains the yarn supply package P1 from the holding unit 32. In this configuration, since the yarn supply package P1 is held in the holding unit 32, the yarn supply package P1 can be obtained from the holding unit 32. Therefore, in the package replacement device 7, it is not necessary to go to the storage position to take the yarn supply package P1 each time the yarn supply package P1 is replaced. The recovery device 40 located at the working position transfers the recovered yarn supplying bobbin B1 to the holding unit 32. Therefore, in the package replacement device 7, it is not necessary to return the collected yarn supplying bobbin B1 to the storage position every time the package replacement is performed. Thus, in the package replacement device 7, the work efficiency can be improved with respect to the replacement of the yarn supply package P1.

The bobbin 24 according to the present embodiment includes a rotating mechanism 25c that rotates the yarn supply package P1. The joint device 60 has a first rotation mechanism 62 and a second rotation mechanism 63 that drive the rotation mechanism 25c of the bobbin 24. In this configuration, when the yarn Y is pulled out from the yarn supply package P1 by the yarn splicing device 60, the yarn supply package P1 supported by the bobbin 24 can be rotated. Therefore, when the yarn Y of the yarn supply package P1 is caught by the yarn splicing device 60 and pulled out, excessive tension can be prevented from being applied to the yarn Y. Thus, in the package exchange device 7, the occurrence of yarn breakage during the yarn splicing operation can be suppressed. As a result, the package replacement device 7 can improve the work efficiency in replacing the yarn supply package P1.

In the package exchanging apparatus 7 according to the present embodiment, the yarn splicing device 60 splices the first yarn end Y1 of the one yarn supply package P1 and the second yarn end Y2 of the other yarn supply package P1 after the yarn supply package P1 is mounted on the bobbin 24 by the supply device 50. For example, in the configuration in which the yarn supply package P1 is attached to the bobbin 24 after the yarn splicing operation is performed, the entangled yarn Y may be loosened by applying tension or the like to the yarn Y during the operation of attaching the yarn supply package P1. In this case, the replacement of the yarn supply package P1 ends up failing, and the operation must be performed again. In the package exchanging device 7, after the yarn supply package P1 is mounted on the bobbin 24 by the supply device 50, the yarn splicing device 60 performs yarn splicing. Therefore, in the package exchanging device 7, the yarn Y entangled with the yarn feeding package P1 during the mounting operation can be prevented from loosening. As a result, the package replacement device 7 can improve the work efficiency in replacing the yarn supply package P1.
