CS244284B1 - Device for securing the lifting mechanism of the annular bench - Google Patents

Abstract

The solution relates to a device for securing the lifting mechanism of the ring bench of a textile, especially a ring-type warping machine, for creating a pocket or biconical winding, comprising a stepping electric motor, mounted on a fork lever and coupled to a three-armed sensing lever by means of a lifting screw and a nut. The lifting screw nut is provided with a pin on which a double diaphragm is mounted for controlling contactless microswitches, of which two mutually offset contactless microswitches for indicating the upper and upper emergency position of the ring bench and two mutually offset contactless microswitches for indicating the lower and lower emergency position of the ring bench are mounted in an adjustable manner on a holder mounted on the fork lever.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an apparatus for securing an anchor bench lift mechanism for producing a bicyclic winding thereof on textile, in particular annular twisting machines, comprising a stepping electric motor mounted on a fork lever.

In known twisting machines, the locking mechanism of the annular bench lifting mechanism was indirectly provided by means of a meter counter or by means of limit switches assigned to the annular bench machine. Such ^- protection is, however, unsatisfactory for twisting machines in which the building is winding · controlled stepping mechanism.

SUMMARY OF THE INVENTION The object of the invention is to provide a reliable and structurally simple device for securing the lifting mechanism of an annular bench, which is also suitable for twisting machines intended for processing very fine, especially glass fibers.

This is achieved by a device according to the invention, which consists essentially in that the nut is provided with a pin on which a double diaphragm is mounted for operating the proximity microswitches, two offset contactless microswitches for indicating the upper and upper emergency positions of the annular bench and The offset contactless microswitches for indicating the lower and lower emergency positions of the annular bench are mounted adjustably on a bracket mounted on the fork lever.

The device according to the invention is advantageous for its simplicity, reliability and maximum accuracy with respect to the desired function of the lifting mechanism of the annular bench in the processing of fine, especially glass fibers.

Further advantages and features of the present invention will become apparent from the description of an exemplary embodiment illustrated in the accompanying drawings, in which: Figure 1 is a partial cross-sectional front view of the device;

a side view of the device of FIG. 1.

The stroke mechanism for forming the winding on the ring twisting machines consists of a three-arm pick-up lever 2, which is hinged in its arm on the pin 2. In the other arm of the three-arm pick-up lever 7 is a pressure roller 2 » a basic stroke (not shown) of an annular bench for generating winding. The winding can be coppy or parallel biconical according to the cam 4. The third arm of the three-arm pick-up lever 7 is rotatably mounted with a nut 5 through which the stroke screw 6 of the stepping electric motor 7 passes. to which is connected the rod 2 of the lever mechanism (not shown) of the annular bench.

On the fork lever 8, a stepping electrometer 6, which receives regular pulses from a known central meter of meters, is freely suspended on the pin. With transmissions not shown, which is part of the stepping motor 2 »receives the alternating stroke movement of the lifting bolt 6. The rotation of the screw 6 inches nut 5 rotates three armed sensing lever 2 · This changes the angle oC between the three armed sensing lever 2 ^{and the} forked lever 8. This change the angle is achieved by gradual lifting of the annular bench up to the maximum position of the full winding on the spool to produce a coppy winding.

The pin 16 of the nut 2 j ^e disposed double diaphragm 10, which controls the non-contact microswitches 12, 22 »2Δ» 12 ^»of which two mutually offset proximity microswitches 12, 14 are intended to indicate the upper and emergency upper position of the ring rail and two likewise mutually offset non-contact microswitches are designed for indication of lower position and lower emergency position

244 284 ring benches. As mentioned, the proximity microswitches 12 ' are mounted adjustably on a holder 21 mounted on the fork lever 8 of the lift mechanism.

The function of the device is as follows:

Changing the angle of the PC between the three armed sensing lever 2 ^{and the} forked lever 8 gets the double diaphragm 10 between each proximity microswitches 13, 2H @ »12 ^and according to its position activates the corresponding proximity microswitch 22 22 * 11» 12 · Depending on which of the proximity microswitches 12 »12» pour »12 3 ^e double diaphragm 22 is closed, or open, ring twisting machine is started or stopped with the full package and the required weight of the coil.
