The invention relates to textile engineering.

A known hoist shaft to a weaving machine, containing a series of eccentrics, each of which is mounted on a separate shaft and kinematically connected with hedges, a control system and a motion transmission unit to the eccentrics, made in the form of a system of gears and couplings.

In order to expand the assortment of fabrics produced, the control system of the proposed heald carriage contains switches, one for each eccentric, a series of fan-shaped relative to one center rigs carrying protrusions for interacting with the switches, and means for reciprocating movement of the grams having a pair of toothed discs and an asterisk located between them, fixing the position of the t g, each setting of the g with the possibility of periodic interaction with the teeth of the disks, with publicly rapnortu pattern.

In addition, each coupling can be provided with a spring-loaded lock.

FIG. I depicts the proposed docking carriage, general view; in fig. 2- the same, front view of the control system; in fig. 3 - the same, top view; in fig. 4 shows the transmission unit to the eccentrics;

on fng. 5 - the same, right side view of the coupling part; in fig. 6 shows the shape of the hole in the movable part of the coupling.

The remisable carriage contains a series of eccentrics 1, wrapped around the connecting rods 2, pivotally connected to two shoulder arms 3, which are kinematically connected with remises (not shown). Each eccentric is mounted on a separate shaft 4 mounted in racks 5. The carriage has motion transmission units to the eccentrics, each of which contains gear 6 and clutch 7. Gear 6 is in engagement with gear 8 fixedly mounted on the shaft 9, on which an asterisk is fixed, received from the main shaft of the machine.

Each coupling 7 consists of a movable along the axis of the shaft 4 of part 10 and a non-movable part 11. Part 11 is made integral with gear 6 and has a tooth 12 with a bevel 13. Part 10 is mounted on shaft 4 by means of: -:;::

On the other hand, a hole 17 is made. The eyelet, the movable part 10, carries a retainer 18, which must be positioned so that the distance between it and the tooth

15 was enough to accommodate the tooth 12. The carriage also contains a switch made in the form of two fingers 19, having the possibility of reciprocating movement in the guides 20 by means of hinge-connected links 21. The link 21 is pivotally connected to the two-arm lever 22, freely seated on axis 23 and controlled by the control system. The lever bears protrusions 24 and 25. The control system is designed as a series of t 26, located fan-shaped relative to one center 27. Each bar has one protrusion 28 and 29 at one end, which have the ability to interact with the protrusions 24 and 25 of the lever 22 of the switch . This end of the thrust is located in the guide 30, with a spring-loaded spring 31 and freely seated on the axis 32. At the other end of the thrust there are rollers 33 and 34. Discs 35 and 36, which are integral with an asterisk 37 located between them. The disk 35 is rigidly connected to the gear 38, which also sits freely on the shaft 9. On the inner side of the disk 35 there are teeth 39, which are designed so that when the roller 33 contacts these teeth, the tires 26 pull up. On the inner side of the disk 36, there are teeth 40, the shape of which provides for lowering the thrust rod 26 when the roller 34 contacts these teeth. The disk 35 has holes 41 for the passage of the needles 42. Each needle is located in the guides 43, spring-loaded 44 and cooperates with the program tape 45. The clutch clamp 18 is located in the hole 46 and spring-loaded 47. The spring 10 of the coupling is spring-loaded 48. The hole 17, made in the movable part of the coupling, has a descent 49. The carriage operation is carried out as follows. The central shaft 9, through the sprocket mounted on it (not shown), receives rotation from the main shaft of the machine and transmits it through gears 8 gears 6 and, therefore, to parts of the E-couplings. If there is a hole in the program tape, the needle 42 under the action of the spring 44 will take the extreme right position (see Figs. 1 and 3) without affecting the pull of 26. The ha ha 26 under the action of the spring 31 will move to the disk 36 and will go its own roller 34 on the tooth 40. The disks 35 and 36 rotate slowly. When the disk 36 rotates, its tooth 40, acting on the roller 34, moves it from the upper position (see Fig. 2, dashed line) to the lower position. At the same time, the ha 26 descends, acting with its protrusions 28 on the protrusion 24 of the lever 22. As a result, the lever 22 will open. The upper (according to the drawing) pin 19 is shifted to the right, while leaving the hole 17 of the coupling part 10. The lower finger 19 moves to the left and acts on part 10, causing it to shift towards part I. Part 10 takes a position in which its tooth 15 can engage with tooth 12. In this case, the rotation of part I will be transmitted through teeth 12 and 15 on part 10 and through the key 14 on the eccentric shaft 4. The eccentric 1 sitting on the shaft begins to rotate, together with the connecting rod 2, swinging the shaft 3, which, through a system of arms and arms, transfers to the shafts. Having rotated 180 °, part lO of the coupling will take a position where the hole 17 coincides with the axis of the lower (according to the drawing) pin 19, under the action of the spring 48 and due to the bevels 13 and 16 will move to the right. In this case, the lower pin 19 will enter the hole 17. The teeth 12 and 15 come out of the engagement and the shaft 4 stops. The eccentric, sitting on the shaft, will stand in a fixed position, providing a heel for a shade. The cam will continue until the program tape 45 acts on the needle 42. Under the action of the tape, the needle will move to the left (but the drawing), act on pull 26 and deflect it towards the disk 35. At the same time, the movement of the needle is coordinated that the ton at the moment of deflection is located in the gap between the teeth of the sprocket and freely passes through the sprocket. Having deviated to the disk 35, t ha will go down with its roller 33 on the tooth 39 of the disk. The disk, as already noted, slowly rotates. At the same time, its tooth 39, acting on the roller 33, moves it from the lower position to the upper position. A ha 26 rises and acts with its protrusion 29 on the protrusion 25 of the lever 22. As a result, the lever 22 is deflected. The lower (according to the drawing) finger is shifted to the right, while exiting from the hole 17 of the coupling part 10. The upper pin 19 moves to the left and acts on the part 10, causing it to shift towards the part 11. In this position, the teeth 12 and 15 can engage. The rotation of the part 11 through the teeth 12 and 15 is transmitted to the part 10 and through the key 14 to the eccentric shaft 4. The eccentric 1 starts to rotate, and the movement of the shims goes. Turning 180 °, the coupling part 10 will take a position in which the hole 17 will coincide with the axis of the upper pin 19, and under the action of the spring 48 and due to the bevels 13 and 16 will move to the right. At the same time, the upper pin 19 will enter the hole 17. The teeth 12 and 15 come out of the engagement and the shaft 4 stops. Eccentric 1 again stands in the locked position, ensuring a heave remise. The ha 26 is held in a position received by it under the action of the needle 42 through the end portion of the teeth of the sprocket 37 until the closest gap between the teeth of the sprocket is opposite to it. The movement of the sprocket is consistent with the movement of the program tape. Claim 1.
