SU980175A1 - Device for continuous winding of wire - Google Patents

Description

The invention relates to electrical engineering, namely to the cable industry, in particular to equipment for non-continuous winding of wires.

A device for continuous winding of a yarn is known, in which a yarn is wound on a first bobbin, and then without stopping is transferred to a second bobbin using a nip located next to and serving to hold the yarn, the nip being a ring with a core whose diameter is smaller than the inner diameter adjacent to it a hollow core L 1

The disadvantages of this device are low reliability of the gripping mechanism when winding flexible wires and the complexity of service.

The closest to the proposed technical entity is a device for continuous winding of a wire, which is intended for non-stop reception of the wire on the drums and provided with a grip that holds the wire during its passage from a full drum to an empty one. On the drive panel, an imets disk is larger than the diameter of the cheek drum, on the periphery of which there are two locking mechanisms. When moving to an empty drum, they push the cheek of the drum and grip the wire. The wire is gripped by a cylindrical rod with a pointed end that provides a smooth, shock-free entry.

10 wires in the grip mechanism. The rod automatically enters the cylindrical groove of the gripping mechanism, reliably pressing the wire 2j to it. The disadvantage of the device is

15 complexity of the design of the capture mechanism, which leads to an increase in the complexity of its maintenance and configuration.

The purpose of the invention is to simplify the design and increase reliability.

This goal is achieved by the fact that the gripping mechanism is made in the form of two combs, installed one

25 parallel to the other, with the teeth of the combs having a bevel in the upper part for pinching wires and arranged offset from each other, and the width of the teeth is less than the distance between them. Fig. 1 schematically shows the device; figure 2 - the mechanism of capture, end view; in FIG. 3, view A in FIG. 2; Fig. 4 is a view B of Fig. 2. The device comprises a gripping mechanism 1 which is mounted on the drive flange of the drum and consists of two combs 2 and 3 connected by means of locating pins 4 in such a way that each tooth 5 of one comb is against the space 6 between the teeth of the other. The teeth of the combs have a rectangular shape in cross section, and their width is less than the distance between the teeth. The teeth of each comb are chamfered and together form a wedge-shaped groove, expanding in the upper part to a width of greater amplitude of oscillations of the driving state wire. To increase the reliability of gripping and holding the wire, the teeth have sharp edges on the bevels. At the end of the gripping mechanism, there is a knife part 7 serving to cut the wire. Folding the device 8 is located on the lever 9, and the pushers 10 and fixed n.ozhi 11 - on the frame between the receiving drums. The transfer of the wire from the filled drum to the empty one and the operation of the locking mechanism is carried out as follows. On command from the control panel, the empty drum is rotated, the folding device 8 approaches the drum cheek facing the drive flange carrying the gripping mechanism 1. The folding device lever 9 brings the wire to the empty drum, and the pusher 10 moves it to the drive flange in the movement area of the mechanism for wadding, which picks up the wire stretched from the filled drum to the empty one. After reaching the point of pinching in the wedge-shaped groove, the wire is located between the teeth 5 of the combs 2 and 3 in a wave-like manner, while the edges of the teeth securely hold it at the time of cutting carried out by the knife part 7 and the fixed knife 11 of the lifting device. When removing the filled coil, the wire is easily removed from the wedge groove in the opposite direction. The receiver's operation was tested at linear wire speeds of 10 to 200 m / min, as a result of which there was no wire break from the gripper when transferring it from one drum to another. The proposed device for continuous wire winding, equipped with gripping and holding mechanisms, is characterized by simplicity of the gripping mechanism and versatility, allowing transfer from one drum to another wire of any external size to the maximum limited width of the base of the wedge groove without requiring any adjustment . The device allows reducing the laboriousness of the preparatory work, increasing the reliability of gripping and holding the wire when transferring it from one drum to another, which will lead to an increase in the time of continuity of work and reduction of waste, Formula of the Invention knives for cutting the wire, differing in the fact that, in order to simplify the design and increase reliability, the gripping mechanism is made in the form of two combs, one set parallel to the other, with the teeth of the combs having a bevel in the upper part for clamping the wires and arranged offset from each other, and the width of the teeth is less than the distance between them.
