SU123064A1 - Device for stopping power in case of thread breakage of twisting machines - Google Patents

Description

A device for stopping power when a thread breaks on a torsion machine is known with stopping the discharge roller and a wire single-arm lever holding a hook-probe and releasing the frame of the discharge roller to leave it when the thread breaks. The disadvantage of this device is that it causes an arbitrary cessation of power, resulting from a change in the tension of the thread, without breaking the latter.

The described device eliminates this drawback by the fact that, directly behind the hook-shush, along the thread, there is a fixed wire rod, which perceives fluctuations in the tension of the thread and stabilizes the tension of the thread in the area where the hook-probe is placed.

The drawing shows a kinematic arrangement. The exhaust roller / mounted on frame 2 is pressed to the nylon 5. The frame 2 in this position is supported by a single-arm wire lever 4 carrying a hook probe 5 and releasing the frame 2 for the exhaust roller to leave the cylinder 3 when the thread 6 is broken. Immediately behind the hook By the probe 5, along the thread 6, a fixed wire rod 7 is mounted under the latter, which is subject to fluctuations in the tension of the thread 6.

The device works as follows. The thread 5 moving between the rotating cylinder 3 and the discharge roller / to the spindle (not shown in the drawing) of the twisting machine, moving through the hook-shun 5, supports the single-shoulder wire lever in the raised position, which in turn supports the frame 2, pressing the outlet I roller to cylinder,. When the thread 6 is broken, the hook-probe 5 with the lever 4 goes down (indicated by the dotted line in the drawing).

releasing the frame 2 of the discharge roll I, as a result of which the latter departs from the cylinder, and the power is stopped. In order to eliminate the arbitrary cure from the change in tension of the yarn 6, the wheel of tension in the tension: takes on a fixed wire rod 7, thus stabilizing the tension of the feed 6 in the area where the hook probe 5 is placed, as a result of which the power supply stops only when the wire breaks piti 6.

Subject invention

The device for stopping the power when the thread breaks on the twisting machines with the shutter of the grader roller and the wire single-arm lever holding the hook-probe and releasing the frame of the discharge roller to leave it when the thread breaks, it is that, in order to eliminate the arbitrary termination of feeding, we get a breaker, in order to eliminate the arbitrary discontinuation of food, we get a patient who has received a breaker. due to a change in the tension of the thread, directly behind the hook probe, along the thread, a fixed wire rod is installed under the latter, which perceives oscillations in the tension of the thread and stabilizes the tension ie yarns at the site where the probe hook-placed.
