Description

The invention relates to the production of artificial yarns in a continuous manner and can be used in textile industry and the production of chemical garments.

The purpose of the invention is to expand the technological capabilities of the device by performing thread refilling with a continuously moving ring bar of the machine.

FIG. 1 shows a device, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section BB in FIG. 2

The device contains a cylindrical chamber 1 with a lid 2 fixed on it and an annular cavity 3 for threading the yarn 4. The chamber 1 by the discharge branch pipe 5 is connected to an air suction system (not shown), mounted coaxially to the spindle 6 of the machine under its ring bar 7 and fixed to this the plank. In the cap 2, an annular groove 8 and nozzle openings 9 are evenly spaced around the spindle and connected with the groove 8. The chamber 1 has a nozzle 10 connected to the annular groove for connection to an air injection source (not shown). In the branch pipe 5, a means for separating the thread is placed, representing by itself a pair of knives 11 placed at a distance from one another.

The device works as follows.

During the production time of the package 12, the ring strip 7, together with the ring 13, reciprocates according to the law defining the shape of the package winding. The thread 4, the passage through the slider 14 moving around the ring 13 receives twisting and is wound on the package 12 rotated by the spindle 6. When the package reaches the specified outer diameter, the spindle turns off, the package rotates and the slider weakens the thread tension between them and the thread in this area starts to sag due to continuous feed. When the spindle is turned off, the air suction is turned on through the outlet pipe 5 and the annular cavity 3.- The loop is sucked by them into the annular cavity 3 at any stop position. vivhego runner. The thread entrained by the jet of suction air bends around the knives smoothly without touching. At the time of the removal of the package, the thread is pulled and cut by the knives. The thread continues to flow into the air suction system, passing through the slider. Ring bar continues to make. reciprocating motion. After installation, on a spindle

 empty chuck 15 include spindle,. turning off the air suction and simultaneously supplying compressed air to the nozzle 10 through the bore 8. to the holes 9. Air jets flowing out of the holes 9 deflect the thread between the slider and the cavity 3 to the cartridge 15, and the thread is pulled simultaneously from under slider and pipe .5 (Fig. 2, position I). At the time of touch. :

0 the thread of the surface of the rotating chuck is fascinated and wound onto it (Fig. 2, position II). The tension in the branch of the thread increases rapidly, it also stretches and cuts 5 HTS. knives 11. After that, the compressed air supply stops. Threading finished.

The proposed design of the device provides the extension of its functionality by capturing and threading the spindle masking for the production of viscose textile yarn in a continuous way, without stopping the ring bar, which allows you to automate the re-threading and use automatic money management. .
