SU38498A1 - Device for stopping the warping machine when the thread breaks - Google Patents

Description

The present invention has in mind the stopping of the warping machine when the thread breaks.

In the schematic drawing of FIG. 1 is a side view of the proposed fixture; FIG. 2 is a view of the switching device of the warping machine using a spring; fng 3 is the same as FIG. 2, but with the use of a piston;, FIG. 4 is a view of part of the belt shifter.

The proposed device consists of the following, his. Threads 1, like those of warping machines, pass under the studs 2 hanging on them, which fall when the threads break, fall between the rollers 3. The rollers 3 are insulated both from each other and from the machine itself, and being included in electrical circuit, open it. One roller is connected by wire to one pole of electromagnet-4, the other roller is connected to the pole of the transformer, the second pole of which is connected to the other pole of electromagnet 4. Above the electromagnet there is a short end of the pawl 5, the long end of which latches the three-arm 6, which has a turning point at point 7 On the shoulder and the lever 6

(216)

the load 8 hangs. The short lever arm 6 with the dog 5 snapped in is located at some distance from the rod 9, at the end of which is a report 10 for the belt. On the rod there is a protrusion 11, which, when the belt is moved to the working position by the lever 12, snaps onto the frame of the machine 14, being pulled to it by a spring 13. When the thread breaks, the falling pin produces an electrical circuit in the circuit, the magnet starts to act, attracts the end dogs 5, which, jumping off, releases lever 6, the latter, being always under the influence of load 8, immediately leans back, rotating around point 7 in the direction opposite to the hour hand.

Tilting, the lever & its short end strikes the bar 9 and knocks it out, and the protrusion 11 jumps off the retaining frame 14 and under the influence of the spring 15 advances the bar inside the machine, arching the belt onto the idler pulley (Fig. 2). Instead of a spring, it is possible to use a piston moving with compressed air (Fig. 3). Rod 9 together with the slider goes as long as neckline 16

in the bar will not rise before the lever of the lever 6, which, by the action of the load 8, is not corrected. in © goes to this cut-out: The movement of the barbell is stopping, and at the same time the belt will be EOLTENED on the idler pulley. This stitching the end of the lever 6 into the notch 16 of the rod 9 in turn will not allow the machine to be started up until the rod 6 has been brought into a vertical position and is secured by the pawl 5, Thus, starting the machine without charging it stop mechanism is not possible.

In order not to keep the magnet in current when the machine is stopped, a current interrupter is used in the circuit, which is served by the same lever 6. In its working position, it closes the circuit with a plate 17, connecting two poles 18 of the circuit.

At the same time that the lever 6 is deflected, the plate comes out of contact with the poles and the circuit is broken.

On the same basis, the pawl cannot snap and hold the bar 6 in a vertical position if there is any contact, for example, if the stud has not failed between the shafts.

The subject matter of the invention.

Claims (2)

1. A device for stopping a machine at a thread break, consisting of moving parts for each thread, falling at a thread break and closing an electrical circuit, characterized in that in order to transfer the belt from the working pulley to the idle one, a three arm b is used that carries a shoulder and the load 8 and intended for releasing the shoulder from the latch 5 when the electric circuit is closed during the break of the thread to move the rod 9 with the fork 10. 2. When fitting in accordance with claim 2, in order to smoothly move the rod 2 to transfer the belt, instead of spring 15, use a spring-loaded piston moving by means of compressed air.
