Description

one

The invention relates to textile machinery, namely to heald slide carriages for a weaving machine.

A known heald slide carriage contains a mechanism for controlling the movement of needles attached to the holders and connected to the control element installed between the hooks and interacting with the latter through the pushers.

In a known heald slide carriage, the control structure includes the use of several connecting elements for each heddle, which complicates the carriage design.

The purpose of the invention is to simplify the design of the heald carriage. This is achieved by the fact that the control is equipped with a fork-shaped lever mounted rotatably by means of a cam disc and carrying a spring-loaded rod with two-sided grips, one of which is designed to interact with the pushrods, and the other with needle holders.

FIG. 1 and 2 depict the described carriage in two working positions; in fig. 3 - spring-loaded t ha with bilateral captures.

At the ends of balance 1 are hinged traction hooks 2, controlled by knives 3. Hooks are supported by spring-loaded studs 4. In the center of balance 1 is pivotally fixed lever 5 associated with shims (not shown). The mechanism for controlling the movement of the needles 6 is made in the form of a patterned map 7 enveloping the drum 8. The needles 6 are fixed in holders 9, each of which

has a protrusion 10 cooperating with a pivoting guide 11. The rear end of the holder is bent. Between the holders there is a block 12, on which the needles 6 are supported through the springs 13. The holders with their bent ends are in contact with one double-sided gripper 14 located at the end of the string 15. At the other end of this rod there is a second double-sided clamp 16. At the ends of the pull there are also blind holes 17, one of which includes a spring 18, abutting against block 12. The other hole includes a guide pin 19 fixed to the forked lever 20 by means of block 21. At the ends of the fork 22

the lever 20 is located rollers 23, running around the cam disc 24, sitting on the drive shaft 25.

To move the pull hooks 2, the pushers 26, mounted on axles 27, can be rotated and spring-loaded springs 28.

The carriage works as follows.

After releasing the holder from the pivoting guide needle 6 under the action of the spring 13, it is pressed with a small force to the patterned card 7. If there is no hole in the patterned map, then all the elements of the carriage adopt the position shown in FIG. 1. If there is a hole in front of the needle 6, as shown in FIG. 2, then the turn guide And through the protrusion 10 will displace the needle into the hole of the patterned card. In this case, the folded end of the holder 9 grips through the grip 14 t gu 15, overcoming the resistance of the spring 18. In accordance with the position of the fork lever 20, its shoulder rotates relative to the hooks 2. In this case the grip 16 acts on the lower end of the pusher 26 and turns it, hook descends in the direction of the knife 3 and is gripped by it. At the next removal

The needles 6, together with the holder 9, by means of the guide 11 from the patterned card 7 tons ha 15 are displaced towards the balance 1 under the action of the spring 18 and release the pusher 26. The latter under the action of the spring 28 rotates under the hook of the hook 2 and supports the hook.
