SU35030A1 - Signaling device to winders when winding a thread of a certain length - Google Patents

Description

In view of the lack of thread spools, they began to produce threads in hanks, balls and on cross-roll cartridges. For the latter kind of winding, winding machines with cutting drums of the Schlafhorst type are very suitable. However, it must be kept in mind that the yarns are usually sold with exactly guaranteed length, which the above-mentioned machines cannot give, since the winding stop occurs depending on the diameter of the wound chuck by installing the rod 11, which, from the 7 / i position occupied by the winding, lifting together with the flyer 9, slides off the protrusion 16. The teat sock off the protrusion, with its deepened end falls on the pin 17 of the rotating shaft ring, which raises and is thrown to the right into the position // s so that the pin of the rod 12 lays on the plane 13. Raise to, rod raises and flier with the cartridge, the latter disengages from contact with the drum 2, and further winding thus stopped. Since the amount of thread wound on the cartridge depends not only on its outer diameter, but also on the winding density and the diameter of the cartridge itself, it is absolutely impossible to reach this stopping device with exactly the same thread length on the cartridge, which causes them to refuse to use the machines mentioned. The present invention aims to eliminate this disadvantage and to provide such an alarm device for winding machines, which, with the possible simplicity, low cost and reliability of its design, would guarantee a certain length of thread winding.

In FIG. 1 shows a general view of the tool and FIG. 1 and 2 parts of the device.

The device consists of a rotating contact 6, rotated from the block, around the winding thread, and a fixed contact 7. When the electric circuit is closed, the lamp lights up, and the worker using the machine switches off the reel wound. The very stop is made by the hand of the worker herself when the warning light 8 is extinguished. For fine winding up to 500 m. (which is mainly required) the worker is able to serve only six to seven drums occupying a small area, and therefore it is not difficult to monitor the flashes and extinction of the bulbs above.

8-10 seconds before the end of the winding, the lamp lights up and thus warns the worker, who, by imposing

yku on the flyer ,. ;; waiting for the time of the yutuhani and the undertaking, to lift it, pull it out, set the winding, refueling the new. cartridge, start the winding again.

For this purpose, an electric tube 8 is placed above each drum. The pole of the pole is connected to the pole of the voltage transformer, then the other pole of the transformer is connected to the fixed contact 7, made in the form of a flat spring, (Stopped on the box 4, and pin 6, / attached to the worm gear, driven by the roller 3, which bends around the winding thread, is connected to the other pole of the light bulb. When the light goes out, i.e. when the winding starts, the pin 6 is disconnected from the spring 7, thus breaking the contact kt. Thread 7, before getting into the drum 2, bends 360 ° around the roller 3 of the counter, rotating it and through the double worm gear also the worm gear 5. The diameter of the roller 3 is calculated so that with one revolution of the gear 5 it becomes necessary to The approach to the intended length, the gear 5 with its pin 6 touches the spring 7, the current closes, and the lamp S lights up; with the further rotation of the gear 5, the pin, bending the spring 7, finally jumps off of it and the light goes out. In order to quickly stop the winding cartridge, which is being wound up by inertia, and at the same time, roller 3, from the difference in the circumferential speed of which the thread can loosen and jump off the roller, an instantaneous stop of roller 5 is arranged, at the same time

and braking. This is done as follows. When stopping, i.e., when the flyer is raised, the boom 7 / takes the position 772 lying down with its pin 12 on the plane 75 of the part; This movement of the rod occurs with a certain impact of the rod on the vertical protrusion 78. At the same time, it strikes the head of the spring-loaded lever JO which, moving to the right, with its end, enters between the teeth of the squirrel's cop (: and with it the counter roller. When the new cartridge is started up, the lever 70 under the influence of the spring 75 (Fig. 2) moves to the left and thereby gives the rotation roller 3 the freedom to rotate.

The subject matter of the invention.

Claims (2)

1.Alarm device for winding machines when winding a thread of a certain length, characterized by the use of contacts 6 and 7 connected to an electricity source, of which contact 7 is made in the form of a flat spring fixed at the box 4, contact 6 is fixed on a worm gear, driven in rotation of the roller 3, around the winding thread. 2. When fitting according to claim 1, use to stop the roller 3 attached to the last squirrel wheel M, between the teeth of which the end of the spring-loaded lever W falls due to the impact of the coiled reels on the head of the rod 77.
