Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is directed to a shuttle that can reliably prevent the weft from being caught between the shuttle shelf and the shuttle, resulting in weft breakage or soiling of the weft. This invention relates to a play ball for adjusting weft tension.

(Prior art and its problems) In the case of a conventional play that fits into the upper and lower sliding grooves provided on the shaft side wall and adjusts the tension of the weft yarn pulled out through the yarn guide hole, as shown in Fig. 11, , the outlet end b of the thread guiding hole a was formed so as to substantially coincide with the outer surface d of the sliding plate of the play piece c. Therefore, when the shuttle e that has been flying all the way is captured by the shuttle box, the weft i is inserted between the braking upright piece g of the shuttle shelf f and the side wall h of the shuttle e, as shown in the figure. If the weft yarn i is caught, especially when the shuttle box moves up and down, the weft yarn i will become even more deeply and tightly caught due to the upward movement of the shuttle box.

When the weft yarns are pinched in this manner, the weft yarns may be cut, damaged, or soiled, resulting in various problems such as a decrease in the quality of the woven fabric and a decrease in weaving efficiency.

The object of the present invention is to provide a play element for adjusting the weft tension in a shuttle that can solve this problem.

(Means for Solving the Problems) A playr (hereinafter referred to as a playr) 1 for adjusting the weft tension in the shuttle of the present invention includes upper and lower sliding grooves 5 located at the outermost side of the side wall 3 of the shuttle 2; A protrusion 10 that protrudes outward on the sliding plate 9 that is slidably fitted into the shaft 5 and pulled toward the end of the shuttle 2 by the elastic cord 7.
In addition, a thread guide hole 11 that opens at the tip of the protrusion 10 is provided to adjust the tension of the weft yarn 12 pulled out through the thread guide hole 11, so that the shuttle 2 is captured on the shuttle shelf 23. When the protruding portion 10 is placed above the braking rising piece 25 of the shuttle shelf 23 so as not to come into contact with it, the outlet end 26 of the thread guide hole 11 is positioned above the braking rising piece 25 of the shuttle shelf 23, and the outlet end 26 of the thread guiding hole 11 is positioned above the braking rising piece 25 of the shuttle shelf 23. It is characterized by being located on the outside.

(Function) However, in the playr 1 of the present invention, when the shuttle 2 is caught on the shuttle shelf 23, the weft yarn is caught on the shuttle shelf 23.
The upper part of the braking rising piece 25 and its inner surface 27
Since the weft yarn 12 is pulled out from the yarn guide hole 11 on the outer side of the yarn guide hole 11, the weft yarn 12 is pinched between the upright piece 25 of the shuttle shelf 23 and the side wall 3 of the shuttle 2 when the shuttle 2 is captured in the shuttle box. can be prevented.

A bending piece 17 that is bent in the opposite direction F2 is arranged substantially parallel to the moving plate 9, and a thread guide hole 11 is formed so as to pass through the bending piece 17 in the inner and outer directions. . The end surface 19 of the columnar piece 16 on the playback drawing direction side is formed in a triangular shape with an upper portion 20 and a lower portion 21 each inclined inward from the center, and the end surface 19 of the columnar piece 16 is The lower surface and the lower surface of the bent piece portion 17 are formed flush with each other. In this embodiment, the thread guide hole 11 is formed using a thread guide hole member 22 made of ceramic, earthenware, resin, or the like. As shown in FIG. 2, when the shuttle 2 is captured by the shuttle shelf 23, the protrusion 10 has its lower end surface 24 slightly raised from the upper end of the braking upright piece 25 of the shuttle shelf 23, In addition, the outer open end 26 of the thread guiding hole 11 is located outside the inner surface 27 of the rising piece 25 (in this embodiment, the outer open end 26 is located approximately above the outer surface 29 of the rising piece 25). (to) be done. The braking rising piece 25 cooperates with the swell 30 to sandwich the shuttle 2 between the two and brake the shuttle.
It functions to stop it.

However, when the shuttle 2 is captured by the shuttle box,
As shown in FIG.
5. Since the weft yarn 12 is pulled out from approximately above the outer surface portion 29 across the outer surface portion 29, when the shuttle 2 is caught in the shuttle box, the weft yarn 12 is pulled out from the rising piece 25.
It can be reliably prevented from being caught between the side wall 3 of the shuttle 2 and the side wall 3 of the shuttle 2. In addition, in this embodiment, in particular, the end surface portion 19 of the protrusion 10 is
