SU51500A1 - The mechanism for stopping tape machines in flax spinning, jute and similar industries - Google Patents

Description

The author's certificate no. 7709 describes a mechanism for stopping tape machines in flax spinning, jute, and similar industries, in the event of a break or running out of a tape, in order to prevent a marriage, the so-called „skip tape. When a tape is skipped, the mechanism automatically transfers the belt from the working pulley to the idler and stops the car regardless of the speed with which it was moving.

Subsequently, according to the dependent author's certificate 35019, a modification of the mechanism, a roller was used that carried a cam, freely mounted clutch, the spring-loaded half of which, sitting on the roller key, was connected to the drive sprocket and moved along it, in order to influence the belt pull-out when the roller stopped during tape break,

In the proposed modification of the mechanism, the cam clutch is disengaged by means of an angular lever, which collapses when the tape breaks at one end between the protrusions of the coupling bush.

In FIG. 1 shows the Shd front of the mechanism for stopping tape machines in flax jute and similar industries; FIG. 2 is a vertical cross section of it; FIG. 3-view of the mechanism on top.

In the mechanism for stopping tape machines, the tape goes along the guide bar 4, covering the hole in the bar, and with one side rests on the limiting bracket 8. Through the hole passes the corner lever 2, which with the upper end runs into the side, takes The position indicated in FIG. In this case, the lower end of the lever 2 is raised and is above the protruding / O bushing / through which the roller 7 passes. The bushing / rotates through a gear coupling consisting of two parts 6 and 6a. The coupling part 6 is integral with the sleeve. The clutch part 6a sits on a key on the roller 7 and, rotating with the roller, can at the same time move along it. When the belt is on the working pulley, the cutting lever 9 is in the position indicated in FIG. 1, and the two coupling halves are in contact, whereby the sleeve 7 rotates.

When the tape breaks, the hole in the strip 4 opens, the lever 2 deflects the upper end to the right and rests on the limiting bracket 8. At the same time, the lower end of the lever is lowered (indicated by the dotted line in FIG. 1) and, west between the projections JO, prevents further rotation of the sleeve 7 When the sleeve 7 stops, the roller 7 continues to rotate by means of the gear 5, while the coupling part 6a b-6a also rotates with the roller 7. Due to the fact that part 6 of the coupling stops as connected to the sleeve 7, and part 6a continues to rotate, clutch divergence , and part 6a moves to the right on the key. The clutch part 6a is connected to the cutting lever 9, therefore the upper part of the lever will be deflected to the right, and the lower part of the lever will slide the branch and the belt onto the idler to stop the machine.

To refill the new tape and start the Machine, by the end of the broken ribbon, they roll out a new tape, then the lever 2 is set to its original position and the tape is placed over the opening of the strip 4. After this machine is used in the normal way.

The subject matter of the invention.

Modification of the mechanism for stopping belt masks in flax spinning, jute and similar industries according to the author's certificate No. 7709, characterized in that angular lever 2, is used to disconnect the cam clutch when the tape breaks and to turn off the drive. passing at one end through the opening of the strip guide 4 for the tape and falling down at the other end when the tape breaks between the projections JO of the sleeve / connected to the part 6 of the coupling 6-ba.
