Abstract

The invention relates to the textile industry, in particular to a centrifugal spinning machine, and permits an increase in productivity. A clamp and two thread conductors connected to the yarn break sensor are connected in series with the spinning machine and spinning centrifuge, which can be moved to the yarn rewind unit if it is broken, fixedly mounted on a fixed support on the outside of the centrifuge. One of the thread guides is located at the package holder to accommodate the yarn at the end of the receiving package, and the other thread guide is installed in the middle part of the yarn pickup fan along the receiving package. 1 hp ff, 3 ill.

Description

The invention relates to the textile industry and relates to a centrifuge spinning machine for producing yarn from various types of fibers.

The aim of the invention is to increase productivity.

FIG. 1 shows a general scheme of the machine in the position of forming a yarn; in fig. 2 - the same in the position of refueling the yarn in the rewind unit; in fig. 3 - the same, top view.

The centrifugal spinning machine at each spinning location contains a pulling device 1, a pneumatic reel 2, a spinning centrifuge 3 with a yarn dispenser 4 installed in the form of a tube 5 with a drive 6 of its reciprocating motion and a rewind unit yi on the receiving package.

Between reel 2 and centrifuge 3 successively in the direction of movement

The yarn has a fast break 8 yarn sensor connected to clip 9 and two thread guides 10 and 11. The guides 12 are placed between these elements, and the guide tube 13 is fixed between the thread guide 11 and the spreading tube 5.

The centrifuge has a rotational drive 14 and is closed by a guard 15.

The rewind unit is permanently mounted on the fixed support 16c of the outer side of the centrifuge 3 and contains a wrapper-holder 17 for mounting the receiving package 7 with its rotational drive, which is, for example, a winding drum 18, which also spreads the yarn along the receiving package 7.

Thread guides 10 and 11 are mounted to move to the rewind unit when the yarn is broken. The clamp-facing thread conductor 10 is mounted to move toward the package.

the holder 17 for placing the yarn at the end of the receiving package, and the conductor 11 can be placed in the middle part of the yarn layout fan for filling it into the rewind unit marker.

The thread guide 10 is located at the end of the lever 19, having a drive 20 for its rotation, which is, for example, a pneumatic cylinder.

The machine works as follows. After acceleration of the centrifuge 3 to the operating frequency, compressed air is fed into the reel 2 and turns on the exhaust device 1. The sliver escaping from the exhaust device undergoes rotating torsion in the reel by rotating air flow and directs it to the centrifuge, where its end touches the inner wall is pressed against it and begins to rotate with it, as a result of which, the given actual twist is reported. The strand is wound in the centrifuge in the package 21 and laid out along it by the distributor tube 5, the law of displacement of which is set by its drive 6,

In the event of a break in the yarn, which most often occurs in the zone of the exit of the sliver from the exhaust device, the sensor 8 sends a signal to the clamp 9, and the exhaust device turns off. The clamp catches the end of the broken yarn. At the same time, the thread guide 11 is moved by the lever 19 to the packer-holder 17 of the rewind unit, carrying the yarn along with it and placing it at the end of the receiving package 7 (Fig. 3). In this case, the drive of the winding drum 18 and the drive of the receiving package 7 are turned on. The thread guide 11, also fascinated by the yarn, is placed in the middle part of the distributor fan along the receiving package so that it leaves the centrifuge and feeds on the winding drum and winds on receiving package 7. The process of rewinding a yarn from a centrifuge to a receiving package is completed after the yarn has completely left the centrifuge. Then, the lever 19 with the guide wire 10, the drive 20 returns to its original position;

The thread guide 11 takes the initial position, after which the stretcher is turned on and the yarn formation process is resumed.

In the case of a complete package inside the centrifuge, the upper position of the tube 5 (not shown) sends a signal to the clamp and the exhaust device stops, after which the process of rewinding the yarn from the centrifuge to the receiving package is repeated.

When a specified diameter is obtained, the receiving package 7 is removed by the package holder 17 and sent to the winder, where, when rewinding, yarn defects are removed and its ends are joined. In the packer set empty

core.

The presence of a rewind stationary stationary outside the centrifuge on each spinning place of the machine allows maximum use

0 centrifuge and change the speed of rewind of yarn in a wide range, thereby increasing the twist of yarn, which helps to reduce its breakage in the area of the torsion triangle at the exhaust device.

5 During the formation of the yarn and its rewinding to the receiving package, the centrifuge rotates continuously without any stops.

The implementation of automatic rewinding of yarn at each breakage and at the end of the package life inside the centrifuge allows the centrifuge to rotate continuously without interruption, which contributes to an increase in productivity, which

5 is determined only by the rotational speed of the centrifuge.

In addition, this automatic rewinding eliminates the need to find the end of the yarn on the package.

0 inside the centrifuge, which also improves performance.
