[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn hooking device for hooking a yarn on a bobbin inserted into a bobbin holder at the time of starting the spinning winder (at the beginning of operation).

[0002]

2. Description of the Related Art First, the basic structure of a turret type spin winding machine will be described with reference to FIG. The body frame 7 is provided with a vertically movable box 1, a rotatable turret plate 2, and a fixed frame 18 having an operation box 10 at the end. A touch roller 3 and a traverse device 4 are respectively supported on the lifting box 1, and the touch roller 3 is in pressure contact with the thread layer of the bobbin B at the winding position, and the bobbin B is rotationally driven counterclockwise. There is. Further, the traverse device 4 is provided with a traverse guide 6, and the traverse guide 6 engages the yarn Y and travels in the traverse range to traverse the yarn Y. Turret plate 2
Is rotatable about a rotating shaft 14 by a rotation drive device (not shown), and two bobbin holders 15 and 16 are rotatably supported by the turret plate 2 respectively. One end of each bobbin holder 15 and 16 is supported. Several bobbins B forming the slit 17 (six in the figure) are mounted, one bobbin holder 15 is located at the winding position a, and the other bobbin holder 16 is located at the standby position b. The bobbin B of the bobbin holder 15 located at the winding position a is made to wind the yarn, and the turret plate 2 is set to 1 each time the bobbin B is fully wound.
The yarn is passed to the empty bobbin which is newly rotated at the winding position a by rotating 80 degrees. In this way, it is possible to
The bobbin holders 15 and 16 for books are wound up alternately. A swivel separator 31 for preventing the yarn end of the full bobbin B at the standby position b from being caught by the empty bobbin B at the winding position a is rotatably supported by the shaft 31a.

By the way, in this turret type spinning winder, the yarn transfer from the full bobbin B to the empty bobbin B can be automatically performed by continuous operation by a yarn transfer device (not shown). When starting before continuous operation, it is necessary to manually thread the bobbin using a thread hooking device. The yarn passing device will be described later.

Such a conventional thread hooking device will be described with reference to FIG. The conventional thread hooking device includes a cylinder device 140,
It is composed of the turning separator 31 and the yarn hooking is performed by the joint work of both. The cylinder device 140 is attached to a lever 141 that swings around a shaft 31a, and is swingable by a fluid pressure cylinder (not shown) between a retracted position indicated by a two-dot chain line and an operating position indicated by a solid line. The cylinder device 140 includes a tubular body 142, a thread hooking member 143,
And a rod 144. The thread hooking members 143 are the number of bobbins B, and the thread hooking members 143 are slidable in the cylindrical body 142. The thread hooking members 143 are connected to each other at a predetermined interval by a belt (not shown). The member 143 is fixed to the tubular body 142. Rod 14
4 penetrates the thread hooking member 143, and only the thread hooking member 143 at the right end of the drawing is connected to the tip of the rod 144. When the rod 144 is pulled out from the tubular body 142 by pulling the knob 144a of the rod 144, the thread hooking member 143 gathers at the left end of the tubular body 142 as illustrated. When the knob 144a of the rod 144 is pushed to put the rod 144 into the cylindrical body 142, the thread hooking member 143 deploys at a predetermined pitch P determined by the length of the belt as shown in FIG. In addition, the turning separator 3
1 is provided with guide grooves 31b at a predetermined pitch P.

The operation of the above-described conventional thread hooking device will be described with reference to FIGS. 3 and 4. In FIG. 3, the turning separator 31 is set to the standby position b as shown, and the cylinder device 14
0 is swung from the retracted position indicated by the chain double-dashed line to the operating position indicated by the solid line, and the rod 144 is pulled out to gather the thread hooking member 143 at the left end of the drawing. Then, each yarn Y fed out through the traverse guide 26 passes through between the touch roller 3 and the traverse device 4 (the yarn removing guide 28 is turned on as shown in the figure so that it does not get caught in the traverse guide. ), The air sucker 27 is collectively sucked. Then, one of each yarn Y is hung on the yarn hooking member 143. Next, as shown in FIG. 4, the knob 144a is pushed to push the rod 144 into the cylindrical body 142. The thread hooking member 143 comes to a predetermined position where it is deployed at the pitch P, and the thread Y also travels right below. Next, the turning separator 31 is turned in the direction. Each yarn Y enters the guide groove 31b, the yarn path is bent to the bobbin B side of the bobbin holder 15, and each yarn Y
Is caught by the slit 17 of the bobbin B and the winding on the bobbin B starts. At the same time, the yarn removing guide 28 is turned off, each yarn Y is engaged with the traverse guide 6, and the traverse winding is started. According to the above yarn hooking method, each yarn Y is simultaneously caught by each bobbin B.

In the above-described spinning winder, after the yarn is hooked at the beginning of operation, the turret plate and the yarn passing device switch the positions of the full bobbin B and the empty bobbin B, and the full bobbin B. The thread is automatically transferred from the empty bobbin to the empty bobbin B. This yarn passing state will be described with reference to FIG. When the bobbin at the winding position a is fully wound, the turret plate 2 rotates 180 degrees to switch the positions of the two bobbin holders 15 and 16, and the full bobbin B is located at the standby position b and the empty bobbin B is It is newly positioned at the winding position a and is in the state shown in the drawing. However, when the empty bobbin B is newly located at the winding position a, the supplied yarn is still connected to the full-winding bobbin B at the standby position b, and the yarn is captured in a slit (not shown) of the empty bobbin B. Only after the start of winding, the transfer of the yarn from the full bobbin B to the empty bobbin B is completed.

An outline of the yarn passing device used for switching the yarn from the full bobbin to the empty bobbin will be described below. When the yarn is switched, the traveling yarn Y connected to the full-winding bobbin B that has moved to the standby position b is guided to a slit (not shown) provided outside the traverse width of the empty bobbin B, and the gathered yarn is full. The yarn passing is performed by a joint operation of the yarn passing device 20 that prevents the yarn from falling from the winding bobbin and moves the yarn across the slit.

The yarn transfer device 20 has a structure in which a slide guide 21 and a fixed guide 22 are vertically arranged at the tip of a partition plate 30. The slide guide 21 and the fixed guide 22 prevent the yarn path to the full bobbin B from shifting.
It operates so as to catch the traveling yarn Y in a slit (not shown). The partition plate 30 can be moved up and down by swinging and swinging from a storage position in the fixed frame 18 indicated by a two-dot chain line to an operating position indicated by a solid line. When the full bobbin B is wound onto the empty bobbin B, the yarn passing device 20 at the tip of the partition plate 30 is positioned between the bobbin holders 15 and 16, that is, between the empty bobbin B and the full bobbin B. There is. The partition plate 30 functions as a first separator in the space between the empty bobbin B at the winding position a on the upper side and the full bobbin B at the standby position b on the lower side, which covers the left side of the left and right sides. To do. A swirling separator 31 covers the full bobbin B together with the partition plate 30.

The swivel separate 31 is arranged on the opposite side of the partition plate 30, has a size to cover the entire width direction of the fully wound bobbin B and the opposite side surface (right side in FIG. 5), and the main body frame 7
It is pinned by the lower boss and can rotate freely. Normally, it is at the retracted position indicated by the chain double-dashed line, but in the operating position, the tip ends of the yarn passing device 20 and the turning separate 31 face each other as shown by the solid line. That is, the traveling yarn Y is closed between the two so that the yarn passing is not hindered. Therefore,
Between the full bobbin B and the empty bobbin B, the right side of FIG. 5 is partitioned by the turning separate 31 and the left side of FIG. 5 is partitioned by the partition plate 30.

In the above-described spinning winder, the full-winding bobbin B is rotating in the standby position b until just after the yarn is transferred from the full-winding bobbin B to the empty bobbin B, and the full-winding bobbin is rotated by this rotation. The cut yarn end of B is swung around.
However, since the empty bobbin B and the full bobbin B are separated by the partition plate 30 and the swivel separator 31 described above, the cut yarn end of the full bobbin B is prevented from being entangled with the empty bobbin at the winding position a. Has become.

[0011]

However, the fully wound bobbin B in the standby position b after the yarn transfer is rotated by inertia until it stops, and the cutting yarn end of the fully wound bobbin B is hooked by the inertia rotation. It may be caught on the thread hooking member 34 of the device. Therefore, there is a problem in that the cut yarn end of the full-winding bobbin B is entangled with the yarn hooking member 34 guide, and a yarn pulling state may occur during doffing when the full-winding bobbin B is pulled out in the axial direction. Further, there is also a problem that the cut yarn end of the full-winding bobbin B up to the stop hits the yarn hooking device and is scraped, and yarn waste is accumulated to contaminate the inside and the periphery of the take-up winder.

The present invention has been made in view of such problems of the prior art. In view of this, the invention according to claim 1 of the present invention prevents the cutting thread end of the full bobbin from being entangled with the thread hooking guide of the thread hooking device after the automatic thread transfer from the full bobbin to the empty bobbin. It is an object of the present invention to provide a yarn hooking device for a take-up winder. In addition to the object of the invention described in claim 1, it is an object of the invention to provide a thread hooking device of a spinning winder which facilitates thread hooking work. In addition to the object of the invention described in claim 1 or 2, the invention described in claim 3 provides a yarn hooking device for a take-up winder in which the cut yarn end of the full-winding bobbin B is more completely covered. This is the purpose.

[0013]
