[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn winding device having a defective winding prevention device.

[0002]

2. Description of the Related Art In a conventional yarn winding device, as shown in FIG. 5, when winding a yarn on a bobbin 2 mounted on a cradle arm 1, the bobbin 2 rotates in the direction of arrow A.
After the so-called bunch winding 3 is performed on the end of the bobbin, the yarn is wound on the bobbin 2 while traversing the yarn by a traverse device (not shown) to form the package 13 .

However, during winding, the yarn end 5 of the bunch winding 3 is unraveled by the action of centrifugal force as shown by the solid line in FIG. 6, and the yarn end 5 of the package 13 is shown by the dotted line in FIG. There was a problem that it was caught inside and became lint.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a yarn winding device provided with a defective winding prevention device, in which a yarn end of a bunch winding is not wound into a package.

[0005]

[Means for Solving the Problems] Clay for mounting a bobbin
On the dollar arm, a guy extends on the bobbin roll forming surface of the bobbin.
Of the guide, and the portion of the guide that faces the bunch winding forming surface of the guide.
A notch is provided at the upstream edge when viewed in the bobbin rotation direction.

[0006]

[Function] The yarn end of the bunch winding is unwound, and the bobbin rotates
The thread end is separated from the surface of the bobbin by the action of the heart force.
Also, the thread end is guided to the notch of the guide as the bobbin rotates.
As it is pulled into the gap between the guide and the bobbin,
It is wrapped around a bottle.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

The basic structure of the yarn winding device of the present invention is as follows:
It is no different from the conventional winding device, and when winding a yarn on a bobbin 11 mounted on a clade arm 10 as shown in FIGS. 1 to 4, the end of the bobbin 11 rotating in the direction of arrow B After the so-called bunch winding 12, the yarn is wound on the bobbin 11 while traversing the yarn by a traverse device (not shown) to form the package 13.

However, in the present invention, an L-shaped guide 14 extending from the side surface of the bunch winding 12 forming side cradle arm 10 to the bunch winding 12 forming surface of the bobbin 11 is provided as a defective winding prevention device. A V-shaped notch 15 is provided at the edge of the portion 14a of the guide 14 facing the surface of the bunch winding 12 on the upstream side in the rotation direction of the bobbin 11.

Therefore, as shown in FIG. 1, the yarn end 16 of the bunch winding 12 wound around the end of the bobbin 11 rotating in the B direction is unwound, and the rotation of the bobbin 11 receives the action of centrifugal force to cause the yarn to move. Even if the end 16 separates from the surface of the bobbin 11, as shown in FIG. 2, the yarn end 16 is guided to the back of the V-shaped notch 15 of the guide 14 as the bobbin 11 rotates, At the same time, the yarn end 16 is folded into a hairpin shape and drawn into the gap between the back surface of the guide 14 and the peripheral surface of the bobbin 11,
Wrapped around. Therefore, the phenomenon of being caught in the package 13 can be completely prevented.

[0011]

As described above in detail, according to the invention, the present invention is, bobbin
A bobbin bunch winding type on the cradle arm
Providing a guide extending on the surface and forming a bunch winding for the guide
The edge on the upstream side in the direction of rotation of the bobbin facing the surface
Since the notch is provided in the
Cut the guide and guide installed on the cradle arm.
Depending on the cutout, the end of the bunch that has been unwound will be the bunch of the bobbin.
It is wrapped around the forming position. Therefore, the yarn end is
Caught in the cage or around the cradle arm
Can be prevented.
