    ka containing a shock lever mounted with the ability to interact with the weft yarn on a torsion shaft fixed in a clockwork coupling, and a carrier roller in contact with a flat disc cam, the profile of which has areas of energy accumulation and recoil to the shock lever and which is mounted on the drive shaft , fixed in the side frames of the machine, has a water coupling of a one-sided action, the leading coupling half of which is mounted on the drive shaft rigidly, and being pivotally attached, and means of fixation from turning Wash the coupling half in the direction opposite to the direction of rotation of the drive shaft, which includes a ring rigidly mounted in one of the side frames with internal inclined grooves and locking rollers, and the cam is rigidly mounted on the driven coupling half and has additional transition areas between the accumulation and return sections of energy and fulfilled oh. the radius of curvature is larger than the radius of curvature of these sections, while the hinge-rim is mounted inside the ring by the knowledge of the lumufta. FIG. 1 shows the combat mechanism, a general view in axonometry; in fig. 2 and 3 - section A-A in FIG. 1 at different cam positions; Figures 4-6 are embodiments; on . 7-combat mechanism, version of the implementation; n Fig.8 - section BB in Fig.7; n FIG. 9- connection of the spring rod with the frame. Shaft 1 is mounted in the side frames 2 of the weaving machine with the possibility of rotation from the primer (not shown) in the direction indicated by arrow 3. On the shaft, the drive coupling half 4 is fixedly mounted with a driver 5 and driven coupling half 6 with the driver 7 connected flat disk cam 8. Impact lever 9 is mounted in steel, with the possibility of rotation on under the hips 10 (the village is conditionally not shown). In addition, the lever 9 is connected to the frame 2 by means of a torsion bar, the rod And having square ends 12 and 12a. At one end 13 of the lever 9, the impactor 14 is pivotally mounted, interacting with the rapier part 15, laying the weft thread 16 through the shed 17. The roller 19 in contact with the working surface of the flat cam is fixed to the free end 18 of the impact lever 9. The cam surface is provided with a spring torsion bar I1. The coupling half coupling 6 is freely mounted inside the ring 20, which has inclined grooves 21 on the inner surface. Rollers 22 are placed in the grooves. Parts 20-22 form a means of locking the rotation of the coupling half away in the direction opposite to the direction of rotation of the drive shaft. . When the loom is operating, shaft I receives rotation from the drive in the direction indicated by arrow 3. When the drivers 5 and 7 of the coupling half 4 and 6 are in contact with each other, the rotation of shaft 1 is transmitted to cam 8, whose working surface interacts with roller 19 of shock lever 9, pressed to the cam by the elastic force of the torsion element 11. When the point of contact of the roller with the cam approaches the position A (Fig. 2), a starting moment occurs. The section AB of the cam profile is steeply dipping, therefore, in this section, the impact lever 9 and the rapier part 15 are accelerated in the direction of the arrows 23a and 236 (passing the weft thread). Due to the free installation of coupling half 6 on the shaft 1, part of the energy of the torsion bar 22 is transmitted to cam 8. In the section BC, right up to the Deepest C point of cam profile 8, the rotation of the latter is accelerated. At the same time, the fine-tuning 7 at position 7a (Fig. 3) makes the uniform rotation of the driving half 5 of the leading coupling half 4 and a gap 24 is formed between the leads. With further rotation of the parts in the section C + D, the rotational energy of the cam 8 is lifted smoothly through the cam profile by roller 19 is transferred to the torsion bar 11, causing it to twist. On section DE, cam 8 has a circular profile with a radius. In this area, the cam 8 is braked and its speed becomes equal to or less than the speed of the shaft. The driver 5 of the leading coupling half 4 now has the opportunity to catch up with the driver 7 of the driven coupling half 6, enter into contact with it and then transmit the shaft 1 to the cam 8. In the lifting section EF of the cam profile, the missing energy is supplied to the torsion bar, which is then again transmitted to the rapier part 15 during the subsequent insertion of the weft yarn, In the section HA, the impact lever 9 is in the ready position. If, due to the increased energy consumption for friction of the rapier part 15, the energy transferred to the cam section to the cam is insufficient for the roller 19 to overcome the entire next CD segment, then with the aid of the rollers 22 placed in the inclined grooves 21 of the ring 20 the reverse rotation of the cam is prevented. In this case, the cam 8 will stay under the roof until the leash 5 interacts with the leash 7 and provides the most movement of the cam. 59 The presence in the mechanism of such a means of fixation against rotation of the driven half coupling in the direction opposite to the direction of rotation of the drive shaft allows the use of a cam of the simplified profile (Fig. 4). In this case, the cam rotational energy is sufficient only for the roller 9 to reach the DJ point. Further, the cam is at rest due to the locking mechanism against rotation, before the beginning of the interaction of the leads 5 and 7. In the embodiment shown in FIG. 5, the cam 8 has an inertial flywheel 25 associated with it. Its magnitude and efficiency can be adjusted in accordance with optimal mode of movement. FIG. Figure 6 shows an embodiment of a cam 8. with a smoothly rising profile in the section DF from radius r to radius R. In the embodiment shown in FIG. 7 and 8, an example of a constructive embodiment of the shock arm 9 is an additional arm 26, carrying an additional roller 27. This pinch interacts with the auxiliary cam 28 so that the shock arm 9 is subject only to forced movement. In the embodiment of the mechanism shown in Fig. 9, the rod 1 1 is installed in the opening of the frame 2 with the possibility of one-sided rotation. During the unloading of the rod, its tetrahedral end 12 can be rotated through an angle of 30 in the direction of the arrow 30 Due to this, the torsion spring rod 11 is prevented from twisting in the opposite direction. The proposed design of the combat mechanism allows the use of the kinetic energy of the shock lever 3–4 of a partial cocking mechanism by installing a flat cam with the possibility of its one-sided rotation on the shaft and reducing the loads acting on the parts of the mechanism. The invention The combat mechanism of the weaving machine, containing a percussion lever mounted with the ability to interact with the weft thread plotter on a torsion shaft fixed in the winding coupling, and a carrier roller in contact with a flat disc cam, the profile of which has plots of energy accumulation and recoil to the percussion lever and which is mounted on a drive shaft fixed in the side frames of the machine, characterized in that, in order to increase the reliability of operation, it has a single acting drive coupling leading half which is mounted on the drive shaft rigidly and the pivotally hinged, and the fixing means for turning the driven coupling half in the direction opposite to the direction of rotation of the drive shaft, including a ring with internal inclined grooves and fixing rollers rigidly mounted, and a cam firmly mounted on vedo-, my half coupling, and has additional transitional areas located between the accumulation and recoil sections of energy and filled with a radius of curvature greater than the radius of curvature of these teachings stkov, with the knowledge of the coupling half pivotally mounted i inside the ring.
