    The invention relates to the textile industry and concerns a heddle carriage for a loom.
    Known dobby for a loom comprising eccentric with sprung zaschelg Coy pivotally mounted on a drive shaft mounted for intermittent rotation and having at least one radial slot for receiving a latch projection mounted on the eccentric rod coupled to the heddle shaft of the machine, a software mechanism; and at least one control key installed with the ability to interact with the latch for. its disengagement from the drive shaft and pivotally connected to the thrust controlled by the actuator of the program mechanism, the drive element and the lifting knife 1J.
    I.
    A disadvantage of the known device is the low reliability of operation due to the need to install several springs to engage the latch with the drive shaft.
    The purpose of the invention is to increase the reliability of work.
    The goal is achieved by the fact that a heald frame for a weaving machine, comprising an eccentric with a spring-loaded latch, hingedly mounted on a drive shaft, installed with intermittent rotation and having at least one radial groove for accommodating a latch protrusion, mounted on an eccentric rod, connected with a reamer machine, a programmed mechanism and at least one control lever mounted to engage a latch for disengaging it from the drive shaft and pivotally connecting An inline with a thrust controlled by the actuator of the program mechanism, a drive element and a lifting knife has a three-shouldered leash, one arm of which is connected with thrust by means of a link and another is in contact with the actuator of the program mechanism, and two spring-loaded arms installed on the free shoulder of the leash, with the drive element installed with the possibility of alternate interaction with the levers.
    FIG. 1 shows a slide on a carriage, a slit, in the position of engaging the latch with the drive shaft in FIG. 2 is the same with the upper position of the control lever, in FIG. 3 is the same in the latch release position with the drive shaft.
    The drive shaft 1, installed with the possibility of periodical rotation by 180 ° from the main shaft of the weaving machine, has two grooves 2, into which the protrusion 3 can fit, mounted on the axis 4, can be rotated and under the influence of the tension spring 5. connecting latch 6. The latch b rests on an eccentric 7 mounted on the shaft 1 s of the rotational rotation possibility, which is gripped by a connecting rod 8. The last 1 In the node 9 is pivotally connected to the system of transmission levers 10, through which according to arrow 11
    S reciprocating motion of the connecting rod 8 is transferred to the weaving loom shaft. On. Shaft 1 has an appropriate number, for example, from six to twelve, drive elements (Fig. 1), namely, one eccentric 7 and one shaft 8 are provided for each machine hemming.
    I.
    Common parts 1, 7 and 6 form
    5, the so-called eccentric carriage for driving and controlling all looms of the loom. Remixes are moved according to the weave program for the main threads.
    0 in the upper or lower position. To actuate the latch 6, during operation, there are two supported on fixed support pins 12 and 13 with
    The 5 turns of the control knobs 14 and 15 or 16 and 17, the hooks 18 on the free ends, which can turn to the moving section of the latch 6. Both the control levers with their shoulders 15 and 16 in the node 19 are connected by means of a hinge. On the shoulder 1 in the 20 t hectare 21 unit it is supported that it can be rotated and can be connected with a heir to the backbone with a detachable knife 22 moving back and forth according to arrow 23. The hectare 21 has a fork-shaped part 24, which forms a slot 25. The slot has a pin 26, shoulder arm 27 of a three-shouldered leash 27, 28 and 29. The guide can move up and down according to arrow 30 (Fig. 1}. Arm 28 at node 31 and 32 is pivotally mounted, held 5 PIP by creating a so-called pivot spring center spring 33 lever (overload lever) .3 4 and 35 forming the slot 36, the shoulder 28 of the lifting element carries
    0 pin 37, which enters ishitz 36 between levers 34 and 35, In addition, pin 36 enters pin 38 mounted on a drive lever 39, which can be rotated
    5. reciprocating according to the arrow 40. The lever 39 during its operation makes a full stroke up and down, while the shaft 1 rotates to ISO (double stroke method). A software control device for engaging and disengaging the latch 6 is formed by a stationary electromagnet 41, which mohset attract the measles 42 pivoting about the axis 43. The anchor interacts with the probe arm 30 of the driver. By means of the stationary stop 44, the pivoting movement of the control levers 14-17 is limited, since the arm 17 can contact with the stop under the influence of the tension spring | 45. The device operates as follows. If, during the weaving process, the heddle shaft 8 must alternately move up and down alternately, then the latch in the drive shaft 1 (Fig. 1) must remain engaged. For this purpose, the control arms 14-17 must remain in the neutral position (Fig. 1) when the latch, with its free end, passes under one of the hooks 18 of the control arms. During the drive-down movement of the drive lever 39, the head 38 enters the lower one (FIG. 1) of the overload sensor 35. Due to this, first, in the closest position of both the overload levers 34 and 35, the overdrive is moved downward (Fig. 1). . With the downward displacement, the 26 t hectare 21 also turns downward, so that it engages with the helix knife 22. In the last phase of the downward movement of the driving lever 39, the tension of the spring 33 slightly increases as a result of the pivoting downward movement of the lever 35, thanks to What makes the ha 21 under the influence of the spring 33 abut against the heald blade 22 with the provision of dynamic communication. Each time the end of the latch passes under one of the hooks 18, the helix yoke 2-2 and the ha 21 are in the position shown in FIG. 1 in which the arms 15 and 17 of the control arms (Fig. 1) are moved to the right, and the hooks 18 are rotated to the neutral position (Fig. 1), because at the end of the downward movement of the driving lever 39, the spring 33 is slightly more extended , the lift of the lever 39 does not exactly correspond to the lifting motion of the lead ka. Lever 39 makes a certain upward movement. If the heddle rod 8 is to be moved alternately to the upper and lower pharynx, then the measles 42 must not be attracted by the electromagnet 41, but must remain in the retracted locking position (working position, Fig. 1 and 2), the magnet 41 does not receive current from source voltage, it remains unexcited. Parts 21 to 22 move to the left until the shoulder meets the stop 44, and the helix knife 22 enters the left reversing position in which it is raised by the shoulder arm 21. Then the drive lever 39 (Fig. 1) turns up. The axle 38 is brought into contact with the lever 34, and the lever 35 under the influence of the spring 43 follows it. The levers 34 and 35 are in the position with the shortest distance from each other. If the pin continues to move from upwards, then both levers 34 and 35 with the shortest distance from each other and also the leash 27, 28 and 29 move upwards. However, the shoulder 29 immediately falls into the one shown in FIG. 2, a locking position 29, in which the shoulder 29 abuts against measles. 42. In the subsequent upward movement, the pin 38 presses against the lever 34, so that this lever is rotated. in the upper position (Fig. 2). In so doing, the spring 33 is extended, so that the distance between the levers 34 and 35 is increased. The force effect created by the driving lever 39 according to FIG. 2 is guided through the spring 33 to the lower lever-35, which transmits the force through the trunnion 37 to the arm 28, so that this arm is supported by the spring in the mode shown in FIG. 2, the locking position, and thus the shoulder 29., Is held in a spring-loaded, dynamically coupled interaction with the bark 42. The remisable-lifting knife 22 again falls into the position shown in FIG. 2 right position. The control arms 14-17 are again in the retracted, neutral position, the latch b remains in engagement. If the heddle should remain in its position of the upper orifice or the lower orifice, which it has reached, then the latch 6 should be disengaged. This is done in the following way: Remeopod; a removable knife 22 from the one shown in FIG. 1, the right position is moved to the left to its left reversal position, in which there is a gap between the heald blade and the bent part of the bar 21. The ha 21 moves to the left until this movement is og {5increased by both control levers 14 15 and 16, 17 on stop 44. These levers are now in the position shown in FIG. 3 working position 14, 15, or 1b, 17.
    At the same time, electromagnet 41 is energized, so that measles 42 is rotated into the left, neutral position 42a shown in FIG. 3. After the upward movement of the drive lever 39, the leash 27, 28, 29 is moved upward while maintaining the smallest distance between the levers 34, 35 is moved to the upper position according to FIG ... 3. The shoulder 29 now occupies the position 29, which is provided by the neutral position 42 the shoulder 29 is located near the core 42. When the driver moves upward the movement or driving force generated by the lever 39 is transmitted through the axle 38 to the lever 34, the force action from it through the spring 33 is directed to the push-in lever 35. of the flanged pin 33 moves up the leash. At the same time, pin 26 is moved upwards. Due to this, the ha 21 falls into the upper neutral position 21 according to FIG. 3, in which it is disengaged from the heddle knife 22 and with its protrusion rests on the support with the provision of clearance. This stop forms a restriction for the upward movement of the rod 21.
    When the drive shaft 1 is rotated according to the arrow, it is engaged. The latch 6, with its end, comes up on the hook 18 of the turned control lever 16 and 17 according to ig. 3
    In doing so, the latch b is rotated into the one shown in FIG. 3, the disengagement position 6, in which the protrusion 3 is located outside the groove 2. Thereby, the arm together with the latch 6 remains in the last position of the upper or lower mouth. As the parts 39, 27, 29, and 21 of the 21 21 move downwards temporarily, they temporarily fall into the zone of action of the shim-raising knife, however, with the PBS I again lift the lever 39 at the same position, the core 42 immediately returns to the uncoupling position 21 according to FIG. 3. In this way, the heald blade cannot move the tu 21 in FIG. 3 to the right and shift the control arms to the neutral position 14-17. The latch 6 and shimmer therefore remain in the same position as long as. If the pivot unit is to be moved to another position, then the electromagnet 41 becomes idle, so that with the next downward movement, parts 39, 27, 29 and 21 measur 42 move | c to the locking position according to FIG. 1 under the influence of the spring. On the next upward movement of the lever 39, the procedure described on the basis of FIG. 1 and 2 process. The shoulder 29 is in the locked position 29 according to FIG. 2, the ha ha 21 remains in the engagement position and is again moved to the right with the help of the heddle blade 22, so that the control levers 14-17 are brought to the neutral position according to FIG. 1 and 2.
    Under the influence of the spring 5, the latch b again gets into the engaged position according to FIG. 1, so that it can again be gripped by the drive shaft 1. Due to this, the shank is set in motion again and falls into a different pharynx position.
     With the help of the spring 33, the leash and the levers, when moving up and down, are gripped with the aid of the axle 38, while maintaining the smallest distance between the levers 34 and 35 until the path of their movement does not meet an obstacle. There is always the willingness to transfer the spring 33 until, with the aid of the core 42 or the heddle knife 22, the movement of the parts up or down is blocked or restricted.
    The same spring 33 is used for kinematically rigid gripping of parts when moving up and down. Therefore, a particularly reliable way of working is achieved with minimal need for parts.
    Of particular importance is that the spring 33 is not fixed on the rigid fixed part, but simultaneously moves with the driver when attached to both levers 34 and 35.
    Due to the relatively small number and, consequently, the relatively small mass of moving parts in the proposed device, the control movements can be carried out with particularly high acceleration, which is advantageous for achieving a large number of revolutions of the machine.
