(54) DEVICE FOR FILING THREADS TO TEXTILE

MACHINE

A ring and a disc provides for a gap that allows free movement of the runner but one) anon jup (ring for him, under the action of the thread that is unrolled from the drum.

The slider is a two C-shaped guide, connected to each other by a staple, pulled out of the whole with directions,

FIG. 1 shows the described device side view; in fig. 2 is a variant of the runner consonation. The device for storing the yarn contains a .Tiyc 1 core, connected with a stationary winding body 2. The latter is formed by rods 3 arranged symmetrically around the circumference. The rods 3 on one side 4 are fixed in the housing 1, and the ends opposite to the housing 1 are inserted into a fixed rigid flange disk 5 having a central concentric support hole 6 in which the washer 7 of a reduced diameter of a hollow shaft 8 turning inside the winding body can rotate 2. The hollow shaft 8 is based in the bearing 9 of the housing I, and is also connected with the driving pulley 10, which is rigidly seated on the neck And protruding from the housing 1.

The hollow shaft 8 has two eccentric washers 12 and 13, the axes of which are inclined under a certain height to the axis of rotation of the hollow shaft 8.

The lia eccentric washer 13 on the ball bearing 14 rests on an elastic ring 15 not kept from rotating and in which in the hollows between the rods 3 are fixed on one side moving the plates 16, with their ends opposite to the elastic ring 15, connected to the second elastic wheel 17, based on the eccentric washer 12 by means of a bearing skrye1sh 18.

When the movement of the hollow shaft 8 of the plate 16 make an oscillatory motion, and they alternately protrude between the rods 3.

On one side, the hollow shaft 8 is rigidly connected to the disk 19, which is located above the stationary flat disk 5 and, at its periphery, carries an eye 20 that rotates inside the flange 21. At a distance from the flange 21, the guide ring 22 having a T-shaped cross section and forming an endless circular guide.

The guide ring 22 is rigidly connected to the housing 1 by means of a holder 23 and bears the slider 24, which can freely rotate on this ring.

The hollow shaft 8 has a longitudinal opening 25 for the thread 26.

On the winding casing 2 there is a feeding coil 27, which is constantly moving in the direction from the eye 20 under the action of the plates 16, transmitting up the movement to the coil 27, which is upwardly directed, and the swinging movement.

On the continuation of the axis of the hollow shaft 8 on oprede4

At a distance from the winding body 2, there is an eye 28 for the thread connected to the stationary body by means of a bracket 29. On the inner side of the guide ring 22 there is a groove 30 with open edges, into which channels reach at point 31, for supplying flowable

means, and these channels are connected with the feeding devices 32.

Runner 24 may be of another shape. In one embodiment, shown in FIG. 2, it has two guide parts 33 in the form of a C-shaped clamp located at a certain distance, and interconnected by a clip 34, the guide parts 33 cover the guide ring 22 in the same way as slider 24, Thanks to that there is a certain distance between the 1 guiding parts 33, the tilting movement of the slider is excluded (see Fig. 2).

The device works as follows.

The thread 26 passing from the spool (not shown in the figures) passes through the longitudinal hole 25 of the hollow shaft 8. In the latter, the thread passes inside the winding housing 2. After leaving the hole 25, the thread 26 passes to the eye 20, which has a drive ( Figures not shown) transmitting rotation through the pulley and the hollow shaft 8, winds the thread in the form of separate rows of located turns on the winding casing 2. These turns of the thread form a nourishing coil 27,

A probe (not shown in the figures) is provided inside the winding body 2, which turns off the drive of the hollow shaft 8 when a certain maximum length of the feeding skein 27 is reached, so that the further formation of turns on the winding body 2 is prevented,

From the feed coil 27, the thread is pulled through the head of the winding casing 2. With this, the thread passes through the slider 24, which (see, fig. 1) directs the flange to the flange 21 and thus outside the path of the eye 20 to the eye 28, from which the thread directed to separate points of the maschina.

The thread 26, passing through the peephole 28, picks up the slider 24 so that the latter circulates along the guide ring 22.

Since the thread has a certain direction and tension between the slider 24 and the guide ring 22, the dead weight of the thread and / or the air flow cannot contribute to the fall of the threads of the nourishing coil 27. Once the nut coil 27 reaches a certain minimum length, the probe again turns on the drive of the hollow shaft 8, the peephole 20 is turned on again, and the feeding coil 27 is filled until the maximum length is reached, after which the drive of the hollow shaft 8 is turned on again.

Due to the fact that the thread passes between the slider 24 and the inner side of the guide ring 22, the lateral width of the balloon formed by the converging thread is limited, while on the other side, under the action of centrifugal force, the thread is pressed to the inner side} of the guide ring 22, which has a favorable effect on the tension of the thread.

The yarn accumulator can be used to feed more than just one yarn. From the winding body 2, different threads can be fed simultaneously to several places of the device. For this, through a peephole 20, several parallel threads are wound on the body 2, as well. The feed coil 27 consists of several rows of arranged skeins of individual threads. Then, from the nutritious skein 27, all the threads pass through the runway 24 and the peephole 28, from where they get to different places of the device. Runner 24 operates in such a way that the same number of threads is wound from the nutritional skein 27.
