Description of the invention (1) The present invention relates to a lever for operating a weft gripping device in a weft conveying and traction gripper for a shuttleless loom. Especially about lever hinges. ’In the textile market, there is a continuing need for improvements in the weft conveying grippers and the devices mounted on them, so that these components ensure that most modern weaving machines work perfectly, even under difficult weaving conditions. In fact, in order to produce high-quality precious fabrics, weaving machines have to provide higher and higher weaving performance, especially with high yarn tension, the use of thin or fine weft yarns or yarns with other special physical properties, and smaller shedding. Angles; all of them, and high loom working speeds. In order to obtain the above-mentioned high weaving performance, the loom has necessary basic components, such as a pair of weft conveying / pulling grippers, for continuous improvement to ensure the required weft insertion performance and a long working life of the gripper. Especially when designing the gripper, the size of the individual components is gradually reduced to reduce the weight and size of the gripper, so that it can safely withstand alternating stress and reduce the internal load of the loom. In order to meet these requirements, the applicant has conceived and formed a pair of weft conveying / traction gripper improved structures to simultaneously enhance gripper hardness and abrasion resistance and reduce quality. This structure is the subject of European Patent Application No. 9 1 06429 · 6 and its contents are incorporated for reference. In designing the above-mentioned holder pair, in addition to the general structural characteristics, it is also important to reduce the size of the individual components mounted thereon, especially the weft holding device. The present invention relates to this. Of course, the purpose of downsizing is to reduce the overall size of the small gripper, and thus reduce the mass of the gripper and the gripper. The paper size applies to the Chinese National Standard (CNS) A4 (210 X 297).

Description of the invention (2) The shedding angle required to move between the yarns. (Please read the precautions on the back before filling out this page) The inventor noticed the weft gripping device and specifically investigated the problems faced by the smaller structure of the lever required to operate this device. In fact, it is known that the lever for operating the weft clamping device is generally fixed on the holder body with a coaxial fixing device corresponding to its hinge point. The articulation axis of the lever therefore has a corresponding diameter width, which must cover the screws or rivets that anchor it to the holder body. As a result, the diameter width becomes larger and affects the final size of the lever. Therefore, an object of the present invention is to provide an improved fixing system for operating a lever of a weft yarn clamping device (in a pair of weft conveying and pulling clamps of a loom). The fixing system has a more compact structure and a higher height. Mechanical resistance, reducing the size of the holder body that covers the device, while ensuring that the device has an increased resistance to applied mechanical stress. According to the present invention, the purpose is achieved by operating a lever of a weft gripping device in a pair of weft conveying and pulling grippers of the loom, and the lever is fixed on the gripper body through a suitable fixing device. It is characterized in that the fixing device is outside the surrounding surface surrounding the lever. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In the first embodiment of the present invention, the support shaft system includes a cylindrical cavity in the holder body, which can be freely rotated in conjunction with the cylindrical portion fitted with a lever. The cavity is between the cylindrical surface integrally formed with the holder body and the cylindrical surface of the pair of anti-thrust blocks Cypress fixed to the holder body by a fixing device. In the second embodiment of the present invention, the support shaft system includes a pin pivotally connected to the lever. The pin system is housed in a holder in the clamping body, and a paper size at the end of the pin is applicable to Chinese national standards. (CNS) A4 specification (210 X 297 mm) -5-571011 A7 B7 5.

Description of the invention (5) (please first Read the notes on the back and fill out this page) Plastic materials are made of 'such as nylon, and finally added with Teflon or other lubricating materials,' and fixed to the holder body with a screw device, as described in the aforementioned European patent application By. 'The central part of the operating lever 1 is fixed against the cylindrical surface 2 of the support base S by a reverse thrust block 4 (Fig. 3). The anti-thrust block 4 is also made of a thermoplastic material, and includes a cylindrical portion corresponding to the cylindrical surface corresponding to the central portion 1 c of the lever 1 and having a wide width. This structure is completed by using two vertical walls 3 (FIG. 4) supporting the base S, which extend laterally from the two edges of the cylindrical surface 2 and restrict the sides of the adjacent lever 1. The wall 3 includes two opposite holes, one of which is inserted with a pin 6 (FIG. 2) to fix the thrust block 4. The pin 6 passes through the through hole 4 f of the entire block 4 and is fastened or screwed into the opposite hole of the wall 3. The wall 3 is finally provided with a side convex edge 3 η at the top end, and the two convex edges 3 η restrict the protrusion on the thrust block 4, thereby preventing the thrust block 4 from rotating around the pin 6. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. With this arrangement, the lever 1 has only one degree of freedom, that is, it can only rotate about the axis formed by the support base S cylindrical bearing table 2. In fact, the reverse thrust block 4 can prevent the lever from moving in the vertical and horizontal directions, omitting the need for idling, and the wall 3 can prevent the lever 1 from moving horizontally and laterally. By performing the injection molding process of the thermoplastic resin part with a good shape stability material, the rotation axis of the lever 1 (that is, the rotation axis of the cylindrical surface 2 of the support base S) and the weft clamping surface (by a thin plate fixed on the support base 5) have precise alignment. In this regard, in practice, attention should be paid to the good coplanarity between the lever clamping portion 1 a and the support base S (or the thin plate 5) to ensure the uniformity of the pressure applied when the weft yarn slides between the clamping members to prevent This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -8- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 571011 Α7 Β7 5. The invention description (6) will cause fabric defects and / or Spikes that compromise yarn quality (such as causing fiber stripping). The cylindrical surface 2 has a minimum unfolding angle to withstand the elastic spring force of the spring M (see FIG. 1) acting on the front clamping portion 1 a of the lever 1 when the lever 1 is operated without deformation at the operating portion 1 p of the lever. Load acting on leverage. The maximum spread angle of surface 2 should not hinder the movement of lever 1. The proper deployment angle of surface 2 is between 70 ° and 90 °, and the best is 80 °. The development angle of the cylindrical surface of the anti-thrust block 4 corresponds to the development angle of the surface 2, or, if necessary, due to the reduced load of the component during the operation of the lever 1, it can be smaller than the development angle of the corresponding surface 2. If the cylindrical surface of the anti-thrust block 4 has the same deployment angle as the surface 2, the deployment angle of the cylindrical part 1 c of the lever 1 should be wider than the deployment angle of the surface 2 by at least the maximum rotation angle of the lever 1; Under the interference, the correct rotation of the cylindrical portion 1 c in the cylindrical cavity formed between the surface 2 of the support base S and the corresponding cylindrical surface of the anti-thrust block 4 is ensured. From the foregoing, the first embodiment of operating the lever can fully achieve the purpose of the present invention. In addition to the weft clamping function, the lever can actually be reduced in size to eliminate the problem of the lever being embedded in its fixture. On the other hand, the lever 1 is guided in a very precise and reliable manner, which moves between the cylindrical surfaces with a significant unfolding angle; it has great advantages and prolongs the life of the lever because the repeated angle of the lever Wear caused by movement has a much wider surface than traditional pins. Finally, idling can be eliminated by simply replacing the thrust block 4 without involving the lever 1 (which will eventually increase in size) to take into account any wear that has affected the surface 2 of the support base S.

Description of the Invention (7) Figures 5 to 8 show the lever for operating the weft clamping device of the present invention. The second embodiment is applied to a weft traction clamp. Holder situation. In this example, the lever 10 is also bent and forged from cut steel, but its central portion 10c is in the vertical plane • development 'instead of the previous embodiment in the horizontal plane. The central part 10c is drilled at the axis of rotation of the lever 10, and the local surface is hardened. After that, an integral hard metal bushing 11 (produced by water cutting technology and not honing) is inserted into the pivot seat and formed, and is fixed in the seat body by brazing. Thereafter, the lever 10 is inserted into the holder body, and is accurately positioned between two parallel walls 12 forming an end portion thereof, and is fixed to the wall in a freely rotatable manner by using a pin 13. The pins 13 are also formed of an integral hard metal, and one end portion is welded to the end portion of the vertical connection plate 14. The other end of the plate 14 is drilled and connected to one of the walls 12 of the holder body with safety screws parallel to the pins 13; therefore, the screws 15 are properly spaced from the pins, such as 8 to 10 mm. Ο The above arrangement can achieve The purpose of the present invention is to prevent the device for fixing the 10-axis of the lever from interfering with the lever body and thus affecting its size. In fact, according to the present invention, the fixing element including the screw 15 is offset relative to the rotation axis of the lever 10, and its relatedness is only that the diameter of the hard metal pin 13 is smaller (for example, only 2 mm). The bushing 11 and the seat body must therefore be sized according to the function of the small-sized pin 1 3, and are much smaller than the currently used operating lever seat body. The seat body must also cover the fixing screw coaxial with the lever rotation pin. This can significantly reduce the size of the operating lever without hindering the total resistance of the lever. In addition, the reduction in the size of the holes forming the seat body bushing 11 causes less stress on the lever 10 body, thereby extending its working life.
