Description

Wiring system for synthetic fiber yarn

One aspect of the present invention relates to a threading system for synthetic fiber yarns.

A false twisting machine is known, which performs false twisting processing on a plurality of synthetic fiber yarns supplied from a self-supplied yarn package, and winds the processed synthetic fiber yarn in a winding device to form a winding package ( For example, Patent Document 1: Japanese Patent Laid-Open No. 6-200434). The false twisting machine is in a creel that holds a plurality of yarn feeding packages, and two inserts (Peg) are used in a group to continuously supply synthetic fiber yarns. In this configuration, the synthetic fiber yarn supported on the inner side of the yarn feeding package of one insert and the synthetic fiber yarn supported on the outer side of the yarn feeding package of the other insert are connected. Thereby, in the creel, even if the synthetic fiber yarn of one yarn supply package is used up, the synthetic fiber yarn is supplied from the other yarn supply package, so that the synthetic fiber yarn can be continuously supplied.

In this configuration, when the synthetic fiber yarn of the yarn feeding package is used up, a new package needs to be supplied, and the synthetic fiber yarn of the yarn feeding package supported by an insert is required to be supported in The connection of the synthetic fiber yarn in the yarn-feeding package of another insert. Such wiring work (tailing work) is generally performed manually. Patent Document 2 (Japanese Patent Publication No. 7-68010) discloses a work trolley, which can be installed along the creel and used for the operations of replacing and connecting the yarn package body Ride.

The industry is eagerly expecting the wiring device to perform the above-mentioned wiring operations without the use of human hands. In this case, it is desirable to grasp the device instead of the human eye to perform the connection reliably. For example, if the threading by the threading device ends in failure, the guide eye of the synthetic fiber yarn in the winding device disappears, so a large-scale resetting in the winding device is required. If you can grasp that the wiring using the wiring device ends in failure, this situation can be avoided.

Therefore, an object of one aspect of the present invention is to provide a threading system for synthetic fiber yarns that can determine whether the threading performed by the threading device is successful.

The threading system for synthetic fiber yarns of one aspect of the present invention is used in textile machinery, and each of the two yarn supplying packages supported by the yarn supplying package support part is pulled out by pulling out the yarn ends. For connecting yarn ends to each other, the textile machine is equipped with: a creel in which a yarn feeder package formed by winding synthetic fiber yarns containing synthetic fibers on a tube is supported by the yarn feeder package support part; and a processing device that supports The synthetic fiber yarn supplied from the self-supplied yarn package is processed; and a winding device that winds the processed synthetic fiber yarn to form a winding package; and the synthetic fiber yarn wiring system includes: a wiring part , Which entangles the first yarn end as the yarn end of one yarn-feeding package body and the second yarn end as the yarn end of the other yarn-feeding package body to form a continuous synthetic fiber yarn; It can hold continuous synthetic fiber yarn, and if the tension acting on the continuous synthetic fiber yarn is greater than a specific value, it is set in such a way that the momentum from the initial state increases according to the tension; the guide part captures the continuous synthetic fiber yarn It is locked in the locking part, and the catching part is moved to a specific inspection position by generating tension on the continuous synthetic fiber yarn; the walking unit, which supports the base of the wiring part, the locking part, and the guide part along the edge The creel moves; an acquiring part that acquires the movable amount of the locking part relative to the base; and a determining part that determines whether the wiring is successful based on the movable amount acquired by the acquiring part when the guide part is moved to the inspection position.

In the threading system for synthetic fiber yarns of this structure, the continuous synthetic fiber yarn is caught and locked in the locking portion, and the catching portion is moved to the inspection position, whereby the continuous synthetic fiber yarn can be tensioned. Regarding the tension generated by the continuous synthetic fiber yarn at this time, the judging unit derives it based on the momentum obtained by the obtaining unit. If a specific tension can be obtained, it is determined that the first yarn end is connected to the second yarn end. If the tension is found, it is determined that the first yarn end and the second yarn end are not connected. That is, the judging unit can judge whether the wiring by the wiring device is successful.

In the splicing system for synthetic fiber yarns of one aspect of the present invention, the guide part may be positioned at the catching part and the locking part of the continuous synthetic fiber yarn with the entangled part of the first yarn end and the second yarn end. The way between the stop parts guides the continuous synthetic fiber yarn. In this configuration, since tension can be generated in the entangled part more reliably, it is possible to more reliably determine whether the wiring by the wiring device is successful.

In the threading system for synthetic fiber yarn of one aspect of the present invention, the locking portion may have a first locking portion and a second locking portion, and the guide portion can lock the continuous synthetic fiber yarn to the first locking portion. Both the stop part and the second stop part, and the entangled part of the first yarn end and the second yarn end are arranged between the first stop part and the second stop part, and the catch is continuously combined In the state of fiber yarn, guide it to the inspection position. In this configuration, since tension can be generated in the entangled part more reliably, it is possible to more reliably determine whether the wiring by the wiring device is successful.

The threading system for synthetic fiber yarn according to one aspect of the present invention may be further provided with: a recovery device that recovers the tube supported by the yarn feeding package support part; and a supply device that mounts the yarn feeding package to Yarn-feeding package body support part; and a recovery device and a supply device are supported on the base. In this structure, the replacement operation and the threading operation of the yarn feeding package held on the creel can be performed by the threading system for synthetic fiber yarns without manual intervention.

In the splicing system for synthetic fiber yarns of one aspect of the present invention, it is also possible that the locking portion can be rotatably provided with respect to the base, and if the tension acting on the continuous synthetic fiber yarn is greater than a specific value, it is The tension is set in such a way that the amount of rotation from the initial state becomes larger, and the acquisition part acquires the amount of rotation of the locking part relative to the base. In this structure, it is possible to easily and concisely structure the structure of the locking portion provided so as to increase the amount of rotation from the initial state in accordance with the tension.

In one aspect of the present invention, it can be determined whether the wiring by the wiring device is successful.

Above, the entire false twist processing system 1 has been described, and the package replacement device 7, which is one of the characteristic parts of one aspect of the present invention, will be described in further detail below. First, the first guide mechanism 67 and the second guide mechanism 68 will be described in further detail. Furthermore, although the installation positions and orientations of each of the first hook 67a, the second hook 67b, the third hook 67c, the first hook 68a, the second hook 68b, and the third hook 68c are different, The composition is the same. Therefore, here, as shown in FIG. 16, only the second hook 68b will be described in detail, and the remaining first hook 67a, second hook 67b, third hook 67c, first hook 68a, and third hook will be omitted. Detailed description of 68c. In addition, in the following, the tension meter 164 is provided in each of the first hook 67a, the second hook 67b, the third hook 67c, the first hook 68a, the second hook 68b, and the third hook 68c. The tension meter 164 may be provided only in, for example, the first hook 67a and the first hook 68a.

As shown in FIG. 15, the second hook 68 b is inserted into an insertion groove 65 b formed in a base plate 65 a that is a part of the base 65. As shown in FIG. 16, the 2nd hook 68b is set so that the base end part 68ba arrange|positioned below the base plate 65a is set as a swing shaft, and the end part 68bb arrange|positioned above the base plate 65a is set to swing. The base end portion 68ba is fixed to a rotation guide 162 provided so as to be rotatable with respect to a rotation shaft 161a fixed to a part of the base 65. Therefore, when the yarn Y is locked to the second hook 68b and stress acts on the second hook 68b, the second hook 68b and the rotation guide 162 swing integrally. The stress on the second hook 68b caused by the yarn Y is proportional to the tension acting on the yarn Y.

The rotation guide 162 is set in such a way that if the stress acting on the second hook 68b is greater than a specific value, the amount of swing (momentum) from the initial state is increased according to the stress, and is applied to the second hook 68b.

In this embodiment, the rotation guide 162 is connected to the fixed portion 161b which is a part of the base 65 via an elastic member (for example, a spring member) 163. Accordingly, regarding the second hook 68b, if the stress acting on the second hook 68b is greater than a specific value, the amount of swing (momentum) from the initial state according to the stress increases, and if the stress acting on the second hook 68b is Below the specified value, it returns to the initial state.

One end of the rotating guide 162 in the axial direction is connected to the tension meter 164. The tension meter 164 obtains the amount of rotation of the rotation guide 162 relative to the base plate 65a. The rotational momentum acquired by the tension meter 164 is acquired by the control unit 90 described below. In addition, the rotating guide 162 is provided with a rotating electromagnetic coil 165 for forcibly rotating the rotating guide 162. The rotating electromagnetic coil 165 forcibly rotates the second hook 68b in the arrow direction shown in FIG. 19B to release the yarn Y in the locked state in the second hook 68b. The rotating electromagnetic coil 165 is controlled by the control unit 90.

Next, the control unit 90 (refer to FIGS. 7 and 17), which is one of the characteristic parts of one aspect of the present invention, will be described in further detail. The control unit 90 includes a combination of CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), I/O ports, communication ports, etc. Electronic control unit. The program used to control each part is recorded in the ROM. In addition, the functions of the drive control unit 90a and the determination unit 90b described in detail below are executed based on the control of the CPU by reading specific computer software into the hardware such as the CPU and the main memory unit.

The drive control unit 90a controls the first motor 62b of the first rotation mechanism 62 and the second motor 63b of the second rotation mechanism 63 so that the amount of swing acquired by the tension meter 164 becomes the first specific range, and controls the yarn Y to self-feed The roll-out amount of each of the packages P1 and P1. Furthermore, each of the first hook 67a, the second hook 67b, the third hook 67c, the first hook 68a, the second hook 68b, and the third hook 68c is provided so as to be movable more widely than the first specific range. The determining unit 90b determines whether the wiring in the wiring device 60 is successful based on the amount of rotation (the amount of swing of the first hook 67a and the first hook 68a) acquired by the tension meter 164 when the catching and guiding mechanism 61 is moved to the inspection position P61 .

Next, the control, which is one of the characteristic parts of one aspect of the present invention, will be described in further detail. This control is for making the yarn end on the outer layer side of the yarn feeding package P1 supported by the first insert 24a Y1 is connected to the yarn end Y2 on the inner side of the yarn feeding package P1 supported by the second spindle 24b in the yarn connecting device 60, and the yarn end Y1 and the yarn end Y2 are guided to the yarn end Y1 by the catching and guiding mechanism 61 Control of the wiring mechanism 64 hours.

As shown in Figures 18 and 19A, when the threading operation is started, the threading device 60 moves the threading arm 61b of the catching and guiding mechanism 61 so that the suction nozzle 61d is positioned at the arrangement of the yarn supply package P1 supported by the second insert 24b The splicer 10 catches the yarn end Y2 by the suction nozzle 61d. Next, the threading device 60 moves the threading arm 61b in this state to lock the yarn Y of the yarn feeding package P1 supported by the second inserting spindle 24b on the first hook 68a and the second hook 68b, and then the suction nozzle 61d moves to the direction of the adapter 10 supported by the yarn feeding package P1 of the first inserting spindle 24a. Thereby, the yarn Y is drawn out from the yarn feeding package P1 supported by the second insert 24b.

Here, the control when the catching and guiding mechanism 61 pulls out the yarn Y from the yarn feeding package P1 supported by the second spindle 24b will be described. When the yarn Y is locked in the first hook 68a and the second hook 68b, and the yarn end Y2 captured by the suction nozzle 61d is moved in the direction of the first inserting spindle 24a, tension is generated in the yarn Y, And as shown in FIG. 19B, it transmits as stress to the 1st hook 68a and the 2nd hook 68b. Thereby, the first hook 68a and the second hook 68b swing in the direction of the arrow shown in FIG. 19B in accordance with the tension generated on the yarn Y.

The control unit 90 controls the second rotation mechanism 63 based on the rotation amount of the rotation guide 162 acquired by the tension meter 164 to rotate the yarn feeding package P1 supported by the second insertion spindle 24b in the unwinding direction. Specifically, the control unit 90 controls the second rotation mechanism 63 so that the swing amount of the first hook 68a and the second hook 68b becomes the first specific range, thereby controlling the winding amount of the yarn Y from the yarn package P1. . Furthermore, here, it is also possible to control the second rotating mechanism 63 so that the swing amount of at least one of the first hook 68a and the second hook 68b becomes the first specific range, thereby controlling the yarn Y self-supplied yarn package The volume of body P1 rolled out.

In this embodiment, the swing amount of the first hook 68a and the second hook 68b is obtained by using the tension meter 164 as the rotation amount of the rotation guide 162. Therefore, the control unit 90 controls the second rotation mechanism 63 so that the amount of rotation acquired by the tension meter 164 becomes the second specific range corresponding to the first specific range, thereby controlling the yarn Y to be wound from the yarn package P1 Volume out.

For example, when the amount of rotation obtained by the tension meter 164 exceeds the second specific range, the second motor 63b is controlled to rotate the yarn feeding package P1 supported by the second inserting spindle 24b in the unwinding direction. As a result, since the yarn Y is wound out from the yarn package P1, the tension on the yarn Y is alleviated. Here, the first specific range is the amount of swing of the first hook 68a and the second hook 68b converted from the tension range that does not cause damage to the yarn Y.

Next, the catching and guiding mechanism 61 moves the wire arm portion 61b to move the suction nozzle 61d catching the yarn end Y2 to the yarn feeding package P1 supported by the first insert 24a, and the yarn end Y1 is caught by the suction nozzle 61d. Next, as shown in FIG. 20, the threading device 60 moves the threading arm 61b in a state in which the yarn end Y1 and the yarn end Y2 are captured, so that the yarn Y of the yarn feeding package P1 supported by the first inserting spindle 24a is locked in After the first hook 67a and the second hook 67b, the suction nozzle 61d is moved in the direction of the wiring mechanism 64. Thereby, this time, the yarn Y is drawn out from the yarn feeding package P1 supported on the first insert 24a. Furthermore, the yarn Y is continuously drawn from the yarn supply package P1 supported by the second insert 24b.

Furthermore, here, after the yarn Y is locked to the first hook 68a and the second hook 68b, the yarn end Y2 is captured in a state where the yarn end Y1 is captured. Method After maintaining the tension of the yarn Y locked in the first hook 68a and the second hook 68b, the yarn end Y1 is released, and then only the yarn end Y2 is caught by the suction nozzle 61d, so that the yarn Y is locked in the first hook 67a and The second hook 67b. That is, it can also be that the yarn Y supported by the yarn feeding package P1 of the second inserting spindle 24b and the yarn Y supporting the yarn feeding package P1 of the first inserting spindle 24a may be separately pulled out to support the yarn Y After the yarn Y of the yarn feeding package P1 of the second inserting spindle 24b is locked to the first hook 68a and the second hook 68b, the yarn Y of the yarn feeding package P1 supported by the first inserting spindle 24a is locked to The first hook 67a and the second hook 67b.

Here, the control when the catching and guiding mechanism 61 pulls out the yarn Y from the yarn feeding package P1 supported by the first insert 24a will be described. When the yarn Y is locked in the first hook 67a and the second hook 67b, and the yarn end Y1 captured by the suction nozzle 61d is moved in the direction of the threading mechanism 64, the tension is generated in the yarn Y and acts as The stress is transmitted to the first hook 67a and the second hook 67b. Thereby, the first hook 67a and the second hook 67b swing in accordance with the tension applied to the yarn Y.

The control unit 90 controls the first rotation mechanism 62 based on the rotation amount of the rotation guide 162 acquired by the tension meter 164 to rotate the yarn feeding package P1 supported by the first insertion spindle 24a in the unwinding direction. Specifically, the control unit 90 controls the first rotating mechanism 62 so that the swing amount of the first hook 67a and the second hook 67b becomes the first specific range, thereby controlling the winding amount of the yarn Y from the yarn package P1. . Furthermore, here, it is also possible to control the first rotating mechanism 62 so that the swing amount of at least one of the first hook 67a and the second hook 67b becomes the first specific range, thereby controlling the yarn Y self-supplied yarn package The volume of body P1 rolled out.

In this embodiment, as described above, the amount of swing of the first hook 67a and the second hook 67b is obtained by using the tension meter 164 as the amount of rotation of the rotation guide 162. Therefore, the control unit 90 controls the first rotation mechanism 62 so that the amount of rotation acquired by the tension meter 164 becomes the second specific range corresponding to the first specific range, thereby controlling the yarn Y to be wound from the yarn package P1 Volume out.

For example, when the amount of rotation acquired by the tension meter 164 exceeds the second specific range, the first motor 62b is controlled to rotate the yarn feeding package P1 supported by the first inserting spindle 24a in the unwinding direction. As a result, since the yarn Y is wound out from the yarn package P1, the tension on the yarn Y is alleviated. Furthermore, while the control unit 90 controls the first rotation mechanism 62, the control of the first rotation mechanism 62 as described above is continued.

As described above, when the threading device 60 pulls out the yarn Y from the yarn feeding package P1 supported by the second spindle 24b by the catching and guiding mechanism 61, the second rotating mechanism 63 controls the second spindle 24b so that The yarn feeding package P1 rotates in the unwinding direction. Thereby, the tension of the yarn Y when the yarn Y is unwound from the yarn-supply package P1 can be maintained within a specific range. Similarly, when the threading device 60 pulls out the yarn Y from the yarn feeding package P1 supported on the first insert 24a by the catching and guiding mechanism 61, the first rotating mechanism 62 controls the first insert 24a to make the yarn Y The yarn package P1 rotates in the unwinding direction. Thereby, the tension of the yarn Y when the yarn Y is unwound from the yarn-supply package P1 can be maintained within a specific range.

Next, a description will be given of a judging method as one of the characteristic parts of the present invention. The judging method is to use the threading device 60 to connect the outer layer side of the yarn feeding package P1 supported by the first spindle 24a. After the yarn end Y1 is connected to the yarn end Y2 on the inner layer side of the yarn feeding package P1 supported by the second inserting spindle 24b, it is determined whether the yarn end Y1 and the yarn end Y2 are properly connected (interlaced).

The yarn intertwined (wired) by the threading device 60 (hereafter, the yarn end Y2 of the yarn Y of the yarn Y2 of the yarn feeding package P1 supported by the second inserting spindle 24b and supported by the threading device 60 The yarn in the state where the yarn end Y1 of the yarn Y of the yarn feeding package P1 of the first inserting spindle 24a is connected is called "continuous yarn (continuous synthetic fiber yarn) Y0") and is locked in the first hooks 67a, 68a, and 2 hooks 67b, 68b. The threading device 60 operates the rotating electromagnetic coil 165 provided on the second hooks 67b and 68b to release the continuous yarn Y0 from the second hooks 67b and 68b. Thereby, the continuous yarn Y0 is in a state of being caught only by the first hooks 67a and 68a.

Next, as shown in FIG. 21, the threading device 60 moves the threading arm portion 61b of the catching and guiding mechanism 61 so that the hook portion 61e is located between the first hook 67a and the first hook 68a, and the continuous yarn Y0 is locked by the hook portion 61e. In more detail, for example, in the catching and guiding mechanism 61, the entangled part YC of the yarn end Y1 and the yarn end Y2 is located between the catching part of the continuous yarn Y0 and the locking part of the first hook 67a (or the first hook 68a). Capture continuous yarn Y0 in a short time.

Next, the threading device 60 moves the hook 61e upward in a state where the continuous yarn Y0 is captured by the hook 61e to move it to a specific inspection position P61. With this action of the catching and guiding mechanism 61, the continuous yarn Y0 generates a specific tension. The control unit 90 obtains the amount of swing generated by the first hook 67a and the first hook 68a at this time, that is, obtains the amount of rotation of the rotation guides 162, 162 obtained by the respective tension meters 164, 164. Furthermore, the control unit 90 may acquire the amount of swing generated by at least one of the first hook 67a and the first hook 68a.

The control unit 90 determines whether the connection between the yarn end Y1 and the yarn end Y2 is based on the amount of rotation obtained by the tension meters 164 and 164 provided on the first hook 67a and the first hook 68a when the hook 61e is moved to the inspection position P61 success. In other words, the control unit 90 determines whether the entangled portion YC is good. For example, when the hook 61e is moved to the inspection position P61, when the amount of rotation obtained by the tension meters 164, 164 provided on the first hook 67a and the first hook 68a is greater than a specific value, that is, when the continuous When the yarn Y0 has a specific tension, the control unit 90 determines that the yarn end Y1 and the yarn end Y2 are successfully connected.

On the other hand, when the hook 61e is moved to the inspection position P61, when the amount of rotation obtained by the tension meters 164, 164 provided on the first hook 67a and the second hook 68b is less than a specific value (including tension Is 0), that is, when the continuous yarn Y0 is not subjected to a specific tension, it is considered to be the state of incomplete entanglement YC (the state that will be untwisted upon pulling), or the yarn end Y1 and the yarn When the end Y2 is not connected at all, the control unit 90 determines that the connection between the yarn end Y1 and the yarn end Y2 has failed.

For example, the control unit 90 may collectively control the false twist processing system 1 including the false twist processing machine 2, the first conveying device 3, the second conveying device 4, the package replenishing device 6, and the package replacing device 7. The control device (not shown) or a terminal device carried by the operator transmits the determination result. In addition, the general control device that receives the judgment result may cause the display device included in the general control device to display the judgment result or the like. Alternatively, the transmission of the determination result to the above-mentioned portable terminal may be executed by the integrated control device.

In the package replacement device 7 described in the above-mentioned embodiment, the continuous yarn Y0 is caught and locked on the first hooks 67a, 68a, and the catching portion is moved to the inspection position P61, thereby producing the continuous yarn Y0. tension. For the tension generated by the continuous yarn Y0 at this time, the judging section 90b derives based on the amount of swing obtained by the tension meter 164. If a specific tension can be obtained, it is judged that the yarn end Y1 is connected to the yarn end Y2. If the specific tension cannot be obtained Tension, it is determined that the yarn end Y1 and the yarn end Y2 are not connected. In this way, the determining unit 90b can determine whether the wiring performed by the wiring device 60 is successful.

In the package changing device 7 of the above embodiment, the catching and guiding mechanism 61 catches the entangled part YC of the yarn end Y1 and the yarn end Y2 between the catching part of the continuous yarn Y0 and the catching part of the hook 61e Continuous yarn Y0 (refer to Figure 20). Therefore, since it is possible to more reliably generate tension in the entangled portion YC, it is possible to more reliably determine whether the wiring by the wiring device 60 is successful.

In the package changing device 7 of the above embodiment, the catching and guiding mechanism 61 has the first hook 67a and the first hook 68a, and the catching and guiding mechanism 61 locks the continuous yarn Y0 to both the first hook 67a and the first hook 68a. Moreover, the entangled portion YC of the yarn end Y1 and the yarn end Y2 is arranged between the first hook 67a and the first hook 68a, and the continuous yarn Y0 is captured to the inspection position P61. Therefore, since it is possible to more reliably generate tension in the entangled portion YC, it is possible to more reliably determine whether the wiring by the wiring device 60 is successful.

In the package replacement device 7 of the above-mentioned embodiment, there is a threading device 60 that connects the yarn end Y1 and the yarn end Y2 of the yarn feeding package P1 to each other; and a catching and guiding mechanism 61 that connects the yarn feeding package to each other. The yarn end Y1 and the yarn end Y2 of P1 are guided to the threading device 60; the supply device 50, which supplies the yarn feeding package P1 to the creel 20; and the recovery device 40, which recovers the yarn supply bobbin B1 from the creel 20. Therefore, the replacement operation and the connection operation of the yarn feeding package P1 can be performed by the package replacement device 7 without manual work.

In the package replacement device 7 of the above-mentioned embodiment, the first hooks 67a, 68a and the second hooks 67b, 68b are swingably arranged relative to the base plate 65a, and if the tension acting on the yarn Y is greater than a specific value, It is set in such a way that the amount of swing from the initial state becomes larger according to the tension. Therefore, it is possible to easily and concisely construct the structure of the locking portion provided to increase the amount of movement from the initial state in accordance with the tension.
