Description

[Detailed description of the invention] Industrial application field The present invention is a shuttle that absorbs the slack of the weft thread and adjusts the tension of the weft thread by means of a playr that slides in a sliding groove. This relates to a playback stop device that is inserted.

Conventional technology A weft tension adjustment groove is provided on the side surface of the shuttle, and multiple pairs of sliding grooves are provided on the inner walls above and below the tension adjustment groove.
In conventional shuttles equipped with a weft tension adjustment mechanism that slidably fits a player having a thread hole in each sliding groove, either the left or right end of the tension adjustment groove is expanded vertically, and the player is inserted into the sliding groove. After inserting the play child into the sliding groove from this insertion part during shuttle manufacturing, an elastic synthetic resin shown in Figures 2 to 4 is used to prevent the play child from falling out of the insertion part. As shown in FIG. 5, a stopper 1 having a U-shaped cross section is fitted into a playback insertion portion 2. Since the play piece and the elastic string that pulls it are consumable items, the stopper can be easily attached and removed when replacing them.

Problems to be Solved by the Invention In the above-mentioned conventional shuttle, a stopper with a U-shaped cross section is fitted into the playback insertion part, but when the weft unwound from the woodwind is pulled out from inside the shuttle and guided to the thread hole of the playlock, There is a risk that the stopper may slide against the vertical plate 3 on the U-shaped back surface, and in order to avoid this, it may be necessary to move the position of the playback insertion portion toward the center of the shuttle. When the position of the insertion portion is moved in this way, the sliding groove becomes shorter, which has the disadvantage that the length capable of absorbing the slack of the weft becomes shorter. Therefore, the present invention provides a shuttle play stop device in which the sliding groove is made as long as possible and the play child insertion portion is located close to the end of the shuttle without interfering with weft extraction from the inside of the shuttle.

Means for Solving the Problems The present invention includes a weft tension adjustment groove on the side surface of the shuttle, a plurality of sliding grooves on the upper and lower inner walls of the tension adjustment groove, and a playlock having a thread hole in each sliding groove. In a shuttle that is slidably fitted and is provided with a playr insertion part at one end of the tension adjustment groove, the inner bottom surface of the playr insertion part is made of an elastic synthetic resin, and is plate-shaped and has a fixing protrusion on the bottom part. The subject matter is a shuttle stopper, which is characterized by a stopper fitted therein.

The content of the present invention will be explained in detail below with reference to the drawings. 1st
The figure is a side view of a shuttle equipped with the shuttle stop device of the present invention, FIG. 6 is a sectional view along AA, and FIG. 7 is a sectional view along BB. 4 is a shuttle body, which has a weft tension adjustment groove 5 on its side surface;
The upper and lower inner walls of the tension adjustment groove 5 are provided with a plurality of pairs of sliding grooves 6, and each sliding groove 6 has a play piece 7 having a thread hole 8.
be slidably fitted. Reference numeral 2 denotes a playback insertion part, which is made by cutting and widening the tension adjustment groove 5 vertically to the depth of the sliding groove 6 at one end of the tension adjustment groove 5, so that the play child 7 can be inserted into the sliding groove 6 from this part. It's getting old. Reference numeral 1 denotes a stopper which is an important part of the present invention, and is a plate-shaped body made of elastic synthetic resin such as polyurethane resin and has a protrusion 9 on the bottom surface as shown in FIGS. 8 to 10. The protrusion 9 is fitted into the fitting hole 10 provided on the bottom surface and attached to the bottom surface of the insertion section 2. If the thickness of the stopper 1 is made approximately equal to the depth of the sliding groove 6, the heights of the inner bottom surface 11 of the tension adjusting groove 5 and the top surface 12 of the stopper will match. If another protrusion 13 is provided on the back surface of the stopper 1 and is fitted into the fitting hole 14 provided in the shuttle body 4, the stopper 1 can be fitted more reliably.

Operation If the play child 7 is inserted into the sliding groove 6 of the shuttle and the stopper 1 is fitted to the bottom surface of the play child insertion part 2, even if the play child 7 is drawn toward the insertion part 2 by the elastic string 15, the stopper 1 It comes into contact with and is resiliently received and stopped, and does not fall out from the insertion section 2.
When replacing the play piece 7 or the elastic string 15, the play piece can be easily removed by removing the stopper 1.

Embodiment FIGS. 11 to 14 show another embodiment of the stopper of the playback stop device of the present invention. A notch groove 16 is provided vertically in the protrusion 9 provided on the bottom surface of the stopper 1 made of elastic synthetic resin, and a protrusion 17 is provided at the lower end of the protrusion 9, as shown in the cross-sectional view of FIG. The stopper 1 is securely held at the bottom of the playback insertion part 2 by compressing and fitting the cutout groove 16 of the protrusion 9 of the stopper 1 into the fitting hole 10 provided at the lower part and expanding it. .

Effects According to the shuttle stopper device of the present invention,
The stopper that fits into the shuttlecock insertion part is a plate-like body that fits tightly against the bottom of the insertion part, and unlike the conventional stopper with a U-shaped cross section, there is no vertical surface that closes the back of the insertion part, so there is no possibility of weft threads coming from inside the shuttle. The outlet port can be freely selected, and the position of the playback insertion portion can be moved closer to the end of the shuttle, and the length of the sliding groove can be increased accordingly. Therefore, the length for absorbing the slack of the weft can be increased, and the tension of the weft can be kept constant. There is no risk of the weft touching the stopper,
Troubles caused by such contact can be resolved. The stopper has an extremely simple structure and is easy to attach and detach, and when attached, it is securely held and does not fall off. Further, since the stopper has elasticity, it has various effects such as elastically receiving the play child, softening the impact of the play child, and preventing adverse effects on the weft.
