ツトルにおける緯糸張力調整用の遊子に関する。[Detailed description of the invention] (Industrial field of application) The present invention is such that the weft thread that is drawn out through the thread guide hole of the player is guided to the inclined side edge portion of the thread guide hole and pulled out from the upper part of the thread guide hole. The present invention relates to a playr for adjusting the weft tension in a shuttle, which can prevent the weft from being caught between the shuttle shelf and the shuttle, thereby preventing the weft from being cut as much as possible.

の問題を生ぜしめることとなる。(Prior art and its problems) The shape of the thread guide hole of the conventional playmaker, which 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 thread guide hole, is It was formed into a circular shape as shown in the figure. Therefore, the weft b drawn out from the thread guiding hole a is guided to the central portion c of the side edge portion of the thread guiding hole a. Therefore, considering the case where the shuttle running through the shed is caught by the shuttle shelf and suddenly stops moving, the weft b pulled out from the thread guiding hole a
Slack may occur, and the slack portion may be caught between the shuttle shelf d and the shuttle e. If the weft yarn is pinched in this way, the weft yarn may be cut, damaged, or soiled during vertical movement of the shuttle shelf, resulting in various problems such as a decrease in the quality of the woven fabric and a decrease in weaving efficiency. It happens.

りも逆方向に位置する。 In Figs. 1 and 2, the play element 1 of the present invention is slidably fitted into upper and lower sliding grooves 5, 5 provided in the side wall 3 of the shuttle 2, and inserted into a through hole 6 bored on one side thereof. The tension of the weft yarn 10 that is drawn toward the end of the shuttle 2 by the tied elastic cord 7 and pulled out through the yarn guide hole 9 is adjusted. The thread guide hole 9 has opposing side edge portions 11 and 12 at its lower end 1.
The side edge portion 11 is inclined obliquely upward in the opposite direction from 3 as a starting point, and has a V-shape with corner portions 15, 15, 15 formed in an arc shape, and side edge portions 11 on the side in the playback pulling direction and the side in the opposite direction. The upper end 16 is located in the opposite direction than the lower end 13.

Ｖ字状に形成されている。 FIG. 2 shows a state in which the play piece is assembled into the shuttle 2, with the play piece 1 of the present invention attached to the inside and outside. As shown in an enlarged view in FIG. 5, the thread guide hole 19 of the playpiece 17 attached to the center has opposing side edge portions 20, 20 extending obliquely downward in the opposite direction from the upper end 21 as a starting point in a substantially straight line. It is formed in an inclined V-shape.

防止されることとなる。 However, in the play child 1 of the present invention, the weft yarn 10 guided by the inclined side edge portion 11 and pulled out in the opposite direction to the play child drawing direction is automatically moved to the inclined side as shown in the enlarged view of FIG. It is guided by the edge portion 11 and rises to its upper end portion. the result,
Since the weft yarn 10 leaves the thread guiding hole 9 of the outer playlist 1a at its highest height position, even when the shuttle 2 is caught on the shuttle shelf and suddenly stops moving, it is less difficult to move than in the case of a conventional playlist. This causes the weft to be pulled out from a higher position (third
(See the enlarged view of the figure and FIG. 9), the situation in which the weft yarn 10 is caught between the shuttle shelf 22 and the shuttle 2 is prevented as much as possible.

なる。 In addition, when using foil yarn as the weft, the first
As shown by the dashed line in the figure, since the flat part of the weft yarn is pulled out while being in contact with the linear side edge part 11 of the thread guiding hole 9, the weft yarn 10 released from the unwound bundle or the woodwind is drawn out at the side edge part. At step 11, it is subjected to an effective "straining" action, and its curls are well corrected. Incidentally, in the case of the conventional playback, since the thread guide hole was circular, the weft yarn was drawn out while coming into contact with the curved surface of the thread guide hole, and the curling curl could not be corrected satisfactorily. In addition, in FIG. 2, the playr 1 of the present invention is used as the inner and outer playrs, and the thread guide hole 19 of the center playr 17 is formed in an inverted V shape, so that the released weft 10 is inserted into the inner playr. 1b is at the highest height, the central playr 17 is at the lowest height, and the outer player 1a is at the highest height. As a result,
Since the resistance applied to the weft is greater than when the weft is at the same height as in the case of using a conventional playback, the curling of the weft can be corrected even better.

略皆無としうる。 In addition, when the shuttle is captured by the shuttle shelf opposite to the shuttle shelf shown in FIG. Since the selvage of the fabric is stretched, there is less risk of the weft being caught between the shuttle shelf and the shuttle than in the case shown in FIG. 3, but in this example, Since the side edge portion 12 of the yarn guide hole 9 on the side in the direction of attracting the play child is also formed to be inclined in a substantially straight line (see Fig. 1), when the shuttle is caught on the opposing shuttle shelf, It is also possible to expect the effect that the weft 10 leaves the thread guiding hole 9 at a higher position than in the case of a playlock (particularly when the playchild of the present invention is used as the central playchild, this effect is more expected). In this case, there is almost no possibility of the weft yarn getting caught in the opposing shuttle shelf.

As shown in FIG. 4 or FIG. 6, the entire body may be formed as an integrally molded product made of ceramic, earthenware, resin, or the like. Note that when the thread guide hole is constructed using a thread guide hole member, the thread guide hole member is formed using a wire rod 20 bent in a V shape or the like, as shown in FIGS. 7 and 8. Sometimes it is done.

れる効果もある。(Effect of the invention) The playlock of the present invention is designed so that the weft can be guided to the inclined side edge portion of the thread guide hole and pulled out, so that the weft thread is automatically pulled out from the upper part of the thread guide hole. Therefore, it is possible to avoid as much as possible the possibility that the weft yarn is caught between the shuttle shelf and the shuttle, causing weft yarn breakage, weft yarn damage, or weft staining, etc., and it is possible to improve the quality of the woven fabric as well as the weaving efficiency. . Furthermore, especially when the weft yarn is a foil yarn, the above-mentioned effect also has the effect of satisfactorily correcting the curling of the weft yarn.
