[0002]

2. Description of the Related Art In general, a double twisting machine applies a double twist by passing a yarn drawn from a yarn feeding package supported by a spindle through a shaft hole thereof to a paper tube supported by a cradle arm. It is adapted to form a winding and winding package. Then, when the paper tube has wound up all the yarns of the yarn supplying package and becomes a full winding package, the empty yarn supplying package is replaced with a full yarn supplying package (yarn changing), and the yarn supplying is performed. Pull out the thread end from the package (feed), pass through the shaft hole (thread), remove the winding package with full balls from the cradle arm, and support a new paper tube on the cradle arm (deep-lifting). The end of the yarn pulled out from the yarn supply package must be fixed (thread hook).

[0003]

By the way, in the past, these operations (replacement of yarns to yarn hooking) were carried out exclusively by hand. However, in the present day when the frequency of operations such as doffing and yarn feeding has increased with the production of a large variety of small quantities, automation of the above operations has been desired in order to reduce labor and improve productivity.

Therefore, the applicant of the present invention was under various consideration in order to newly provide a processing robot for automatically performing these operations. In particular, when starting winding at the time when the threading operation is completed, it is necessary to apply a predetermined bunch winding to the paper tube, but with a simple mechanism that can be smoothly linked to the operation before and after that, Moreover, there was no device for forming a desired bunch winding.

In view of the above circumstances, the present invention was devised to provide a bunch winding device for a winding package which forms a desired bunch winding with a simple mechanism.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a yarn wound from a yarn supplying package provided at a lower part of a double twisting machine to an end face of an empty paper tube of a winding package provided at an upper part of the double twisting machine is emptied. A device for bunch winding around an end of a paper tube, the moving means reciprocating in a direction inclined up and down with respect to the take-up axis of the empty paper tube, and a moving width provided in the moving means.

In this state, the moving means 65 moves up and down diagonally several times within a predetermined range. This vertical movement is caused by the thread conversion member 6
The guide block 66 and the bunch guide roller 67 of No. 4 convert the traverse motion substantially along the winding axis direction of the paper tube B, and the end portion of the paper tube B is subjected to the bunch winding C having a predetermined width. It After the bunch winding is completed, the thread conversion member 6
4 is lowered to remove the yarn Y from the bunch guide roller 67, passes the yarn Y to the feed roller 10, is folded back upward, and stands by at the origin position.

Thereafter, the yarn Y which is twisted and fed from the yarn supplying package P ₁ via the feed roller 10 is caught by a known traverse guide 79 traversing on the rotary drum 6 and traversed. Full-scale winding of the yarn Y begins.

As described above, the guide block 66 and the bunch for winding the yarn Y on the moving means 65 reciprocating in the direction inclined up and down with respect to the winding shaft of the empty paper tube B in a part of the moving width. Since the yarn conversion member 64 including the guide roller 67 is provided and the yarn Y that has been passed over is guided in a direction substantially orthogonal to the empty paper tube B and slid along the winding axis direction, only the expansion and contraction operation thereof is performed. The thread conversion member 64 with the thread Y
The bunch winding C having a predetermined width can be formed by converting the yarn path. At this time, the width of the bunch winding C can be arbitrarily changed by adjusting the stroke range of the piston rod 70. That is, by changing it according to the type of yarn, etc., the bunch winding C has a good releasing property without breaking.
Can be formed.

Further, this bunch winding device 31 has a traveling carriage 32.
Since it is provided above, the cost can be reduced as compared with the case where it is installed on each weight, and installation adjustment is unnecessary.

Then, the moving means 65 extends below the reciprocating section for forming the bunch winding C, whereby the thread converting member 64 and the thread hooking means 35 or the operating arm 3 is moved.
Since the yarn Y is transferred to and from 6 etc.,
The prescribed operation can be performed smoothly, the control of the processing robot can be simplified, and it contributes to the realization of full automation of the work conventionally performed by hand (replacement of yarns to yarn hooking).

Further, in this embodiment, the clamp cutter 55 is integrally provided on the paper tube chucker 54 so that the thread hooking is performed when the paper tube B is supplied to the cradle arm 4. A complicated mechanism for driving 55 is not necessary, which contributes to space saving of the processing robot.

Although the details of the construction of the operation arm 36 are omitted, any operation arm 36 may be used as long as it can hold the yarn end of the yarn supplying package P ₁ so as to engage with the bunch winding device of the present invention. It doesn't matter.
