Problems to be solved by the invention
[0004]
　When the wax molded body is attached / detached (replaced) in the wax applying device, the pressing member is operated to release the holding of the wax molded body with respect to the support member. After attaching the wax molded body, it is necessary to attach the pressing member so that the wax molded body is held against the support member, but the operator may forget the work. In this case, the wax molded product may fall off or the wax may not be applied to the yarn.
[0005]
　One aspect of the present invention is to provide a bobbin winder capable of avoiding the occurrence of defects in the wax applying device.
Means to solve problems
[0006]
　The yarn winder according to one aspect of the present invention includes a yarn feeder that supplies yarn, a winding device that winds the yarn to form a package, and a waxing device that applies wax to the yarn wound by the winding device. A thread splicing device that connects the device, the thread supplied by the thread feeder, and the thread wound on the package by the winding device, and the thread that captures the thread wound on the package and guides it to the thread splicing device. The wax applying device includes a support portion for supporting the wax molded body, a first position for holding the wax molded body against the support portion, and a support portion for attaching and detaching the wax molded body at the support portion. It has a second position away from, a holding portion movably provided in, and a regulating portion that holds the holding portion in the second position, and the holding portion is an orbit in which the catching device moves in the second position. It is located above, and when it comes into contact with the catching device, it is released from the holding by the regulating part and moves to the first position.
[0007]
　In the thread winder according to one aspect of the present invention, when the winding operation is started after the wax molded body is attached / detached in the wax applying device, the thread splicing is performed by the thread splicing device. Therefore, after the wax-molded body is attached / detached, the catching device moves to catch the yarn wound in the package and guide it to the yarn joining device. In such a configuration, the holding unit is located on the orbit where the capturing device moves at the second position, and the holding by the regulating unit is released by the contact with the capturing device and moves to the first position. As a result, in the thread winder, even if the operator leaves the holding portion in the second position after moving the holding portion to the second position and attaching / detaching the wax molded body, the catching device can be moved. Along with this, the holding portion moves to the first position. Therefore, in the thread winder, the wax molded body is securely held by the holding portion with respect to the supporting portion when performing the winding operation. As a result, in the thread winder, it is possible to avoid the occurrence of problems in the wax applying device, such as the wax molded body falling off or the wax not being applied to the thread.
[0008]
　In one embodiment, the holding portion may be urged to move in a direction that presses the wax molded body toward the thread path side. In this configuration, when the holding portion comes into contact with the catching device at the second position and the holding by the regulating portion is released, the holding portion moves toward the first position by the urging force. Therefore, in the bobbin winder, the holding portion can be reliably positioned at the first position.
[0009]
　In one embodiment, the holding portion may be urged by a torsion coil spring to move in a direction of pressing the wax molded body toward the thread path side. In this configuration, the holding portion can be reliably urged by using a torsion coil spring.
[0010]
　In one embodiment, the catching device is movably provided at a catching position for catching the yarn and a guide position for guiding the caught yarn to the thread joining device, and the catching device moves toward the catching position. May come into contact with the holding portion. In this configuration, since the catching device comes into contact with the holding portion when heading to the catching position, the holding portion can be positioned at the first position before guiding the yarn to the yarn joining device. Therefore, in the bobbin winder, the holding portion can be reliably positioned at the first position before the thread splicing is completed by the thread splicing device, that is, before the winding operation is started.
[0011]
　In one embodiment, the holding portion has a pressing lever for pressing the wax molded body attached to the supporting portion and a protruding portion provided on the pressing lever, and the regulating portion is a leaf spring. The holding portion may be held in the second position by having a locking portion for locking the protruding portion and the protruding portion of the holding portion being locked to the locking portion of the regulating portion. In this configuration, the holding portion can be held at the second position, and the holding portion can be reliably released by contact with the capturing device.
[0012]
　In one embodiment, the regulating unit may magnetically hold the holding unit. In this configuration, the holding portion can be held at the second position, and the holding portion can be reliably released by contact with the capturing device.

Mode for carrying out the invention
[0015]
　Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are designated by the same reference numerals, and duplicate description will be omitted.
[0016]
　As shown in FIG. 1, the automatic winder 1 includes a plurality of winding units (thread winding machines) 3 arranged side by side, a machine base control device 5, and a ball lifting device 7.
[0017]
　The machine stand control device 5 can communicate with each of the plurality of winding units 3. The operator of the automatic winder 1 can collectively manage a plurality of winding units 3 by appropriately operating the machine base control device 5. The machine stand control device 5 is provided with a display screen 5a and an input key 5b. The display screen 5a can display information on the setting contents and / or the state of the take-up unit 3. The winding unit 3 can be set by the operator performing an appropriate operation using the input key 5b.
[0018]
　Each of the plurality of winding units 3 unwinds the thread Y from the thread feeding bobbin SB and winds the thread Y on the winding bobbin WB while swinging the thread Y. In this way, the take-up unit 3 forms the package P. The thread Y may include a core thread. The core yarn is, for example, a monofilament yarn, a yarn, or the like.
[0019]
　When the package P is fully wound (a state in which a specified amount of yarn is wound) in each of the plurality of winding units 3, the ball lifting device 7 travels to the position of the winding unit 3 and is fully wound. The winding package is removed from the winding unit 3, and an empty winding bobbin WB is set in the winding unit 3.
[0020]
　Next, the configuration of the take-up unit 3 will be described with reference to FIG. As shown in FIG. 2, each of the plurality of winding units 3 includes a unit control unit 10, a yarn feeding device (thread feeding unit) 12, and a winding device 14.
[0021]
　The unit control unit 10 includes, for example, a CPU (Central Processing Unit) and a ROM (Read Only Memory). A program for controlling each configuration of the take-up unit 3 is stored in the ROM. The CPU executes the program stored in the ROM. The unit control unit 10 controls each configuration of the take-up unit 3 in cooperation with hardware and software. The unit control unit 10 is configured to be able to communicate with the machine base control device 5. As a result, the operation of the plurality of winding units 3 provided in the automatic winder 1 can be centrally managed by the machine base control device 5.
[0022]
　The thread feeding device 12 is a support mechanism that supports the thread feeding bobbin SB mounted on the transport tray (not shown) at a predetermined position. As a result, the thread Y is unwound from the thread feeding bobbin SB, and the thread Y is pulled out from the thread feeding bobbin SB. As a result, the yarn feeding device 12 supplies the yarn Y. The yarn feeding device 12 is not limited to the transport tray type, and may be, for example, a magazine type.
[0023]
　The take-up device 14 includes a cradle 16 and a take-up drum 18. The cradle 16 has a pair of rotary supports (not shown). The cradle 16 rotatably supports the take-up bobbin WB (or package P) by sandwiching the take-up bobbin WB with the rotation support portion. The cradle 16 can be switched between a state in which the supporting package P is in contact with the take-up drum 18 and a state in which the package P is separated from the take-up drum 18.
[0024]
　The take-up drum 18 traverses the thread Y on the surface of the package P and rotates the package P. The take-up drum 18 is rotationally driven by a drum drive motor (not shown). The package P is driven to rotate by rotationally driving the take-up drum 18 with the outer circumference of the package P in contact with the take-up drum 18. Further, a spiral twill groove is formed on the outer peripheral surface of the take-up drum 18. The thread Y unwound from the thread-feeding bobbin SB is wound around the surface of the package P while being traversed by the twill groove with a constant width. Thereby, the package P having a constant winding width can be formed.
[0025]
　Each of the plurality of winding units 3 includes the unwinding assisting device 20, the tension applying device 22, and the unwinding assisting device 22 in this order from the yarn feeding device 12 side in the yarn traveling path between the yarn feeding device 12 and the winding device 14.

A first capture guide device 32 and a second capture guide device (capture device) 34 are arranged in the vicinity of the thread joining device 26.
[0026]
　The unwinding assist device 20 includes a regulating member 21 that can cover the core tube of the thread feeding bobbin SB. The regulating member 21 has a substantially tubular shape, and is arranged so as to come into contact with a balloon formed on the upper portion of the thread layer of the thread feeding bobbin SB. The balloon is a portion where the thread Y unwound from the thread feeding bobbin SB is swung around by centrifugal force. By bringing the regulating member 21 into contact with the balloon, it is possible to prevent the thread Y from being excessively swung by coming into contact with the thread Y of the balloon portion. As a result, the thread Y can be appropriately unwound from the thread feeding bobbin SB.
[0027]
　The tension applying device 22 applies a predetermined tension to the traveling thread Y. In the present embodiment, the tension applying device 22 is a gate type in which movable comb teeth are arranged with respect to fixed comb teeth. The comb teeth on the movable side are urged so that the comb teeth are in mesh with each other. The tension applying device 22 applies tension to the thread Y by passing the thread Y while bending between the comb teeth in the meshed state. The operation of the tension applying device 22 is controlled by the unit control unit 10.
[0028]
　The tension detection device 24 detects (measures) the tension of the traveling thread Y between the thread feeding device 12 and the winding device 14. The tension detection device 24 outputs a tension measurement signal indicating a measured value of the tension of the thread Y to the unit control unit 10.
[0029]
　When the yarn Y is divided between the yarn feeder 12 and the take-up device 14 for some reason, the yarn joining device 26 includes the yarn Y (bobbin thread) on the yarn feeder 12 side and the take-up device. The thread Y (upper thread) on the 14 side is spliced. In the present embodiment, the yarn splicing device 26 is configured as a splicer device that twists yarn ends with each other by a swirling air flow generated by compressed air.
[0030]
　The thread monitoring device 28 monitors the state of the thread Y traveling on the thread path, and detects the presence or absence of a thread defect based on the monitored information. The thread monitoring device 28 detects, for example, an abnormality in the thickness of the thread Y and / or a foreign substance contained in the thread Y as a thread defect. The thread monitoring device 28 also detects thread breakage, that is, the presence or absence of thread Y in the thread path. A cutter 29 for cutting the thread Y is provided in the vicinity of the thread monitoring device 28. The cutter 29 is operated by the thread monitoring device 28.
[0031]
　The wax applying device 30 is arranged between the winding device 14 and the yarn monitoring device 28.

The pipe portion 34b is rotated by the motor M. When moving from the standby position to the capture position, the second capture guide device 34 moves along a predetermined trajectory.
[0054]
　Subsequently, an example of the operation related to the replacement of the wax molded body W in the wax applying device 30 will be described.
[0055]
　When replacing the wax molded body W, the operator operates the pressing lever 44a of the holding portion 44 to move the holding portion 44 from the first position P1 to the second position P2. When the holding portion 44 is located at the second position P2, the holding portion 44 is held at the second position P2 by the regulating portion 46.
[0056]
　When the holding portion 44 is positioned at the second position P2, the operator pulls out the wax molded body W and the wax plate 64 from the mounting shaft 60 of the supporting portion 42. As a result, the wax molded body W is removed from the support portion 42. Subsequently, the operator attaches the new wax molded body W to the wax plate 64, and then attaches the wax molded body W to the mounting shaft 60 of the support portion 42. After that, the operator operates the holding unit 44 to release the holding of the holding unit 44 by the regulating unit 46. As a result, the holding portion 44 moves from the second position P2 to the first position P1.
[0057]
　When the replacement of the wax molded body W is completed, the operator performs a predetermined operation with the input key 5b of the machine base control device 5. As a result, in the take-up unit 3, the thread joining operation is started, and after the thread joining operation is completed, the winding operation is started.
[0058]
　Here, the operator may forget to perform the work of releasing the movement restriction of the holding portion 44 by the regulating portion 46 after attaching the wax molded body W to the supporting portion 42. That is, the operator may forget to move the holding portion 44 to the first position P1. In this case, the thread splicing operation is started in the winding unit 3 with the holding portion 44 located at the second position P2. Specifically, the first capture guide device 32 moves from the standby position to the capture position, captures the thread Y, and then guides the thread Y to the thread joint device 26.
[0059]
　Similarly, the second catching guide device 34 moves from the standby position to the catching position, catches the thread Y, and then guides the thread Y to the thread joining device 26. At this time, the holding portion 44 is located at the second position P2 in contact with the second capture guide device 34. Therefore, as shown in FIGS. 8 and 9, when the second capture guide device 34 moves toward the capture position, the second capture guide device 34 and the holding portion 44 come into contact with each other. Specifically, the tip end portion (curved portion) of the pressing lever 44a of the holding portion 44 and the second capture guide device 34 come into contact with each other. As a result, the holding portion 44 is released from being held by the regulating portion 46, that is, the locking portion 46b of the regulating portion 46 is released from locking the protruding portion 44b of the holding portion 44, and the holding portion 44 moves to the first position P1.
[0060]
　As described above, in the winding unit 3 of the automatic winder 1 according to the present embodiment, when the winding operation is started after the wax molded body W is attached / detached in the wax applying device 30, the thread joining device 26 is used to join the threads. Is done. Therefore, the first capture guide device 32 and the second capture guide device 34 move to capture the thread Y and guide it to the thread joint device 26 after the work of attaching / detaching the wax molded body W. In such a configuration, the holding unit 44 is located on the orbit in which the second capturing guide device 34 moves at the second position P2, and the holding by the regulating unit 46 is released by contact with the second capturing guide device 34. It is moved to the first position P1. As a result, in the winding unit 3, even if the operator leaves the holding portion 44 at the second position P2 after moving the holding portion 44 to the second position P2 and attaching / detaching the wax molded body W. As the second capture guide device 34 moves, the holding portion 44 moves to the first position P1. Therefore, in the winding unit 3, the wax molded body W is securely held by the holding portion 44 with respect to the supporting portion 42 when the winding operation is performed.
