The invention relates to a device for guiding and threading the yarn on winding masks with a folding capsule injector.

A device for thread filler on winding machines for synthetic fibers is known, in which, under a suction injector directed transversely to the movement of the thread, a second injector is installed in the direction of the moving thread over a stationary slotted thread pipe. After the pruning process and the formation of a backup winding, this injector can be pivotally pivoted away from the flooded pipe. With a full spool, the thread is cut by the thread guide element, since the latter moves impulsively against the elastically fixed cutting edge. At the same time, the suction injector sucks the produced thread until the end of the spool change and the installation of a new spool onto the bobbin holder. Another thread guide element cuts the thread in the same way at the height of the injector injector, which captures the cut thread and begins the process of pruning (DD WP 132 010, class B 65 N 54/22, 1978).

The disadvantage is that at the moment of threading the thread by the thread-guiding elements during the separation process, the thread shifts relatively abruptly forward to the cutting edge. Thin and sensitive threads break to the desired separation between the thread guiding element and the cutting edge, so the injector cannot trap previously broken threads, and the workflow is disturbed.

The aim of the invention is to provide reliable suction and reliable fillet yarn in order to avoid downtime.

The dryness of the invention consists in creating a device for guiding and folding the thread when changing the spools, which provides an almost direct movement of the thread to the needle attachment or suction injector.

The goal is achieved by the fact that the injection of juicers is connected to the four-hinged gear and is designed as a leash, with the four-hinged gear being arranged so that the crank and the leash in the position of the knot line form an almost straight line and the turning point of the linkage lies on the side of the suction injector along the height of the nozzle.

On the thread injector injector, a head is mounted, equipped with a cylindrical bore and a collar, which in the position of the thread pruning engages with gear in the gear recess of the air transfer means rigidly mounted on the casing with an elastic sealing membrane.

Between the suction injector and the injector injector in its position of the stripper and under the injector of the injector in its position of winding there is one cutting device.

FIG. 1 shows a device for thread fillet, side view; Figure 2 is the same, front view; in fig. Figures 3 and 4 show a detailed view of the place where the air is transmitted when the thread is drawn with various sealing membranes; in fig. 5 is a section A-A in FIG. four; in fig. 6 location of the control panel.

A device for cutting the thread is located inside the casing I, which is mounted on the cranimc between the biscuits and the winding device. A threaded threaded tube 2 protrudes into the casing I. In addition, in the casing 1 there is an injector 3 injector connected to a four-hinged transmission and made in the form of its leash, an injector 4 from, pump, pneumatic cutting devices 5 and 6, pneumatically rotary yarn feeder 8. The injector 3 of the stem knuckles made in the form of a leash of a four-hinged transmission are in the process of knotting and come close to the threaded tube 2 with a slit. The crank 9 and injector 3 of the prong-shaped leash in this position form an almost straight line. The center 10 of the rotation of the scenes 11 at the same time lies on the side of the injector 4 suction at the height of its nozzle 12. During the winding process, the injector 3 of the curb is in its original position, the thread 13 runs linearly through it linearly. The cutting device 5 lies between the injector injector 3 at the prong position and the suction injector 4, while the cutting device 6 is behind the injector injector 3, which is in its initial position.

The incoming thread 13 is guided linearly through the injector 3 injector in its initial position to the winding device (not shown 1. After the winding process is completed, the following functions are controlled by software for certain periods: the cutting device 6 is pneumatically operated and the thread 13 is cut through the suction injector 4 is turned on and sucks the continuously released thread 13 until the bobbins are changed and the empty bobbins are put on the bobbin holders. Now the pressure cylinder 14 is loaded with compressed air, the pusher 15 with the lever 16 moves forward. Krivoschip 9 rotates around the center of rotation 17

and set it in the form of a leash, a shepherd 3 bite in front of a thread-water pipe 2 with a slot. This position is shown in fig. KSmontirovapna on the injector 3 priuchiki 1-tin 18 with a cylindrical hole 19 and the flange 20 in this position is covered with a serrated recess 21 installed rigidly on

the casing of the air outlet means 7 having an elastic sealing membrane 22. The cutting device 5 cuts the thread 13 still in the injector 4 and simultaneously

The injector injector 3 from the air transfer means 7 receives compressed air, so that the cut off drink 13 with the injector injector 3 is reliably trapped, fed through the filament

pipe 2 and is blown from the unexposed end of the thread pipe to the spool and is captured there. Capturing the thread 13 and making a backup winding on the spool, the injector injector 3 returns to

its initial position, with the thread I3 being withdrawn from the filament pipe 2 with a slit. The rotation of the injector 3 injector to its original position is rationally performed by such

in such a way that the end of the injector of the injector first turns away from the filament pipe 2 with a slot, and then the whole injector injector 3 is turned around the nozzle 12 of the injector 4 of the suction downwards. The winding process is carried out in the usual manner. The proposed attachment device can be designed in such a way that, in order to use it for several threads, it can be placed one after the other in a common casing, which, being completed with the necessary pneumatic distribution valves, is mounted on the front windrower. Control panels 23 for the respective thread running are provided between the individual devices of the drawbins of FIG. 6. The control program can be optionally connected to the appropriate workers.
