SU1484841A1 - Ribbon loom shuttle - Google Patents

Description

The invention relates to textile machinery and can be used on ribbon-weaving machines and allows you to increase the reliability of work. Weft thread, winding with

the spools, passes through the cyto-conducting eyes, the brake device and contacts the sensors 6 and 7. When the weft thread comes off the spool, the photoelectric sensor 7 is activated and the machine stops. In the process of stopping the machine, a reserve of the weft yarn is activated, the length of which, in order to eliminate duck weave, is equal to the distance between the sensors, while the weft tension is provided by a braking device located in front of the sensor in the course of the weft movement. When the weft yarn is broken between the shuttle and the edge of the fabric, the signal to stop the machine comes from the interrupter of the sensor 6 of electromechanical action.

The invention relates to textile machinery and can be used on tape-weaving machines.

The aim of the invention is to increase the reliability of operation.

The drawing shows a schematic diagram of a shuttle with sensors for controlling the weft thread and the control of the thread on the spool. ten

Shuttle for Lentotkatsky machine includes a housing 1, a spider holder 2 .... and a braking device 3 mounted on the housing 1, a spool 4 located ₍ on the bobbin holder 2. At the exit of the weft yarn 5 from the shuttle the sensor 6 of the weft yarn 5 is mounted, mounted in case 1, In the gathering area of the weft yarn 5 from the spool 4 set-2θ is flax on the case 1 of the shuttle, the sensor 7 controls the weft yarn 5 on the spool 4. Between the sensors 6 and 7 there is a braking device 3 installed at the entrance of the weft yarn 5 to the sensor 6 25

breakage. The sensor 6 breakage of the weft thread 5 can be made photoelectric. For optimal direction of the weft yarn 5, threading eyes 8 are mounted on the body.

The distance between the sensors 6 and 7 is selected in such a way that it provides, when the weft yarn 5 comes out of the spool 4, the reserve 9 of the weft yarn 5, necessary for laying the weft without a panning.

Shuttle works as follows.

The weft thread 5, winding off the spool 4, passes through the thread-conducting eyes 8, the schormozny device 3 and contacts the sensors 6 and 7. When the weft yarn 5 comes off the spool 4, the photoelectric sensor 7 is activated and the ribbon loom stops. In the process of stopping the machine, the reserve 9 of the weft yarn 5 is activated, the length of which is equal to the distance between the sensors 6 and 7, while the tension of the weft yarn 5 is provided by the braking device 3 located in front of the sensor 6 in the course of the weft movement.

When the weft yarn is broken between the shuttle and the fabric edge, the signal to stop the machine comes from the interrupter of the electromechanical sensor 6.

The invention allows to reduce the waste weft yarn in the waste and to simplify the design of the Shuttle.

Claims (2)

Claim 1. Shuttle for ribbon machine, comprising a housing, a bobbin holder and a braking device mounted on the housing, located on the bobbin spool and an electromechanical weft thread break sensor mounted at the exit of the shuttle, and the weft yarn monitoring sensor on the spool, other than that In order to improve the reliability of operation, a sensor for monitoring the weft yarn on the spool is installed in the zone of the weft yarn from the spool, while the braking device is located between the sensors and installed at the entrance of the weft yarn into the sensor va. 2. Shuttle under item 1, characterized in that the sensor control weft yarn on the spool made photo · electric.
