Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traverse shoe which engages with a yarn being wound and traverses it in a spinning winder or the like for winding synthetic fiber yarn into cheese.

[0002]

2. Description of the Related Art In a spinning winder in which high-speed winding of several thousands meters per minute is performed, it is necessary to reduce the weight of a traverse shoe in response to an increase in the winding speed.
Therefore, the width A (see FIG. 5) of the boat-type shoe of the traverse shoe is made as small as possible.

[0003]

[Problems to be Solved by the Invention] In the above traverse shoe, the width A of the boat-shaped shoe is made as small as possible.
Due to repeated stress, fatigue fracture occurs in a relatively short time.

The purpose of this invention is to greatly improve the durability of the traverse shoe.

[0005]

In order to achieve the above object, a traverse shoe according to the present invention comprises a base and a base.
Yarn guide with a yarn guide groove erected on one side of the
Engage with the groove of the scroll cam of circular cross section provided on the other side.
Combined boat- shaped shoe, at the corners of both ends of the boat-shaped shoe
It is a round shoe that widens the base of the boat shoe .

[0006]

[Work] In the traverse shoe configured as described above, the repeated bending stress of the boat-shaped shoe due to repeated use is absorbed by the rounded corners at both ends of the boat-shaped shoe.

[0007]

3 and 4, a description will be given of a take-up winder employing the traverse shoe of the present invention.

The spinning winder has two bobbin holders 2 and 2 directly driven by a motor, and each of the bobbin holders 2 is projected and supported on opposite sides of a rotary shaft, and rotates by 180 ° when doffing. The scroll cam 5 includes a plate 3, a touch roller 4 that contacts the package P being wound at the winding position and sends a signal for controlling the motor of the bobbin holder 2 by detecting its peripheral speed. In addition, the touch roller 4 and the scroll cam 5 can slide integrally upward with an increase in the winding diameter of the package P being wound.

Next, the traverse shoe 1 of the present invention will be described with reference to FIGS.

The traverse shoe 1 of the present invention is engaged with the spiral groove 5a of the scroll cam 5 of the spinning winder as described above, and rotates with the rotation of the scroll cam 5 to form the groove 5a of the cover 6.
, And reciprocate in the axial direction of the scroll cam 5.

The traverse shoe 1 has a base 1a
And a boat-shaped shoe 1b integrally projecting downward therefrom, and a yarn guide 1c projecting from the upper surface of the base 1a.

The base 1a and the boat-shaped shoe 1b are made of synthetic resin and are integrally formed.

The yarn guide 1c is made of fine ceramic, and is partially embedded in the base 1a and the boat shoe 1b. The leading end is formed with a yarn guiding groove 1c 'through which the yarn is guided.

The boat-shaped shoe 1b has the same width as that of the conventional one, and is formed with as large a radius (R) as possible to widen the base of the boat-shaped shoe at both corners. The largest possible radius R means that when the traverse shoe 1 is engaged with the groove 5 a of the scroll cam 5, the radius R is as large as possible as long as the radius R does not contact anywhere on the traverse shoe 1.

When the traverse shoe 1 is configured in this manner, the repeated bending stress of the boat-shaped shoe 1b due to repeated use is absorbed by the rounded portion R, and the width of the boat-shaped shoe 1b is not changed, that is, the traverse shoe 1b is not changed. Although the weight of the boat-type shoe hardly increases, the life until the breakage of the boat-shaped shoe base is broken can be drastically increased by about 70% of the conventional one. In addition, roundness R at both ends of the boat-shaped shoe 1b
Does not affect other peripheral members at all, so that it is not necessary to change parts such as the scroll cam 5 and the cover 6.

[0016]

[Effects of the Invention] The present invention is configured as described above, and has the following effects.

That is, the bases at both corners of the boat-shaped shoe are widened.
Rumarumi does not contact the groove of the scroll cam, without hardly increasing the weight, can be dramatically extended bus life before breakage destruction of boat shoe base. Further, the present invention can be implemented without changing other peripheral members at all.
