SU719517A3 - Loom clamping shuttle - Google Patents

Description

The invention relates to the textile industry and can be used in weaving looms. With zimen.minn shuttles. Known clamp shuttle for the loom, containing two levers, p.meyuchhh on the ends of the x sponge, forming a clamp d. Thread 1. The jaws of the clamping piece of a clamped, clamped bone between their clamping surfaces form an open one on both sides, i.e., over the course of the movement of the threads, a gap to grip the thread. For maximum limitation of double masses, yarn clips are made with narrow jaws. Depending on the type of yarn used, at the clamping point, the thread can be stretched so wide that its end partially protrudes laterally from the clamping gap. This is especially bad when processing yarn from elementary filaments, since it consists of many fibrils, many of which do not fall into the clamping gap. When moving filaments, free fibrils can move along it in the longitudinal direction, resulting in the formation of schschiform like thickened spots. Such yarn threads can cause visible orox fibers. In addition, due to the partial capture of the ends of the threads, the passing of the threads from one clip to another may be inaccurate or even impossible. In the well-known clamping hook, the thread is transmitted, for example, by a pushpole with a clamp, which imposes especially high demands on the accuracy and reliability of the interacting elements, since to open and close the clamps involved in the transfer operation for the wires (home) the current of time is approximately 1 / 50 to 1/100 s. The aim of the invention is to increase the quality of the fabric. This is achieved by the fact that, in the proposed clamping hook, the clamp has stops made in the form of protrusions located on at least one of the end sides of the jaws to the side of the thread clamp line. Limiters are exchanged on different jaws. Limiters can be placed on one of the jaws.

under a straight or obtuse angle to the corresponding surface of the thread clamp.

FIG. 1 shows the proposed clamping hook with sariirno mounted-1-nd levers; in fig. 2 is a view along Stre1k A in FIG. one; in fig. 3 - the option of sponges with limiters placed on different sponges; in fig. 4 is a view along arrow B in FIG. 3; in fig. 5 - some hours of the shuttle in another Bapiiajrre; in fig. 6 is a view along arrow B of FIG. five; on phpg. 7 - zamenilmpoy shuttle with irupppymn levers; pa fpg. 8 - view along arrow У on fpg. 7

The clamping hook contains two two shoulders levers 1 and 2, which are mounted on the trunnions 3 of the support 4. Two lateral ends of the levers 1 and 2 are drawn in the form of 5 and 6, which between their clamping surfaces 8 and 9 clamp the thread 10, the end 11 of which projects outwards at the clamping point.

With the outer side of the lower sponge 6 facing towards the end of 11 pt 6, there are two protrusions protruding above the clamping surface of 8 with protrusions 12 and 13 (see Fig. 2), each of which sides facing each other are located at an iodine angle to The clamping device and the toppost 8 form with it a light-shaped nannatula for the unti 10. For the protection-1 step 10 from the clamping surface 8 in the area between the guide protrusions 12 and 13 is skewed.

FIG. 1, the clamping arm is shown in a closed position, in which two free arms 14 and 15 and arms are secured to the outside by two levers 16 (not shown) so that the jaws 5 and 6 are pressed to each other.

The opening of the zheliyok cheliok is made with the help of an offsetting machine (not nakazana), which is compensated by the drive, which with its two legs 17 is subdivided in a known manner from the side to the outer sides of the free shoulders 14 and 15 of the levers 1 and 2 and compresses the next few arms of the other 16. 10 the fork returns to its original position, the shoulders 14 and 15 of the levers 1 and 2 are retracted under the action of the levers 16 of the spring, whereby the thread 10 is gripped and guided between the two guide lines 12 and 13 in the middle of the erhnostey 8 and 9.

Each nz of two jaws 5 and 6 (referring to Figs. 3, 4) is provided with a protruding iad with a corresponding clampable surface 8 or 9 of the lateral guiding stand - limiter 18 or 19. Regardo; 10Ж1Н1ый from the outside sponge 5

On the inner side of the jaw 6, the stopper 18 is located on the sides vertical with respect to the jaws 8 and 9. Each of the two clamping surfaces 8 and 9 and has a rational position across and right hand side of the construction 10 of the depth 10, which improves the clamping of the threads. Near the limiters 18 and 19, the clamped backs of 8 and 9 are skewed.

According to FIG. 5 and 6, facing each other, the sides of the 01-reader G1 21 p 22 form a V-o6pa3J-ibiii trench, which provides 6ojiee with a precise peeter belt 10. According to FIG. 7, clamping man 1; approx. Formed by a spring clip, fastened to the anchor 23 by seals 24. Two pockets 25, 26 parked in a pre-mounted joint in their form. 5 and 6, the ends are pressed against one another. WITH

The outer side of the Enokpey sponge 6 is the mounting plate 27, on the side of which there are side naravlya protrusions - limb 28 28, 29 (see FPG. 8), protruding above the surface of the grip 8. Each side of the side facing each other side of the two sides of the two face 8. forms obtuse angle with clamping noBepxi-iocTbio.

E; 1I open the clamping hook two controllable nixes of a pair of uncovering elements 30 irizhmayutsya side to the inner, newechnosti clamping legs 25, 26, as a result of which the lip 5, O is retracted from each other, drink 10 is released.
