Multi-strand wire break detection device

Abstract

The invention relates to a multi-strand wire breakage detection device which comprises a support and a fixed seat arranged on one side of the support. The support is connected with the fixed seat through a fixed shaft, a guide wheel shaft is arranged at the front end of the support and the front end of the fixed seat, a plurality of guide wheels are arranged on the guide wheel shaft, and the number of the guide wheels correspond to the number of braided wires in a take-up machine. A base is further arranged between the support and the fixed seat, an insulation seat is arranged in the base, a plurality of channels are arranged in the insulation seat, an upper insulation bar and a lower insulation bar transversely penetrate through the insulation seat, a plurality of metal sheaths are arranged on each insulation bar, the metal sheaths are correspondingly arranged in the channels, the two metal sheaths in each channel are connected with leads, and the leads are connected to an external circuit. The device can detect multi-strand broken wires, and corresponding take-up motors can be automatically controlled to stop. Other motors can take up the wires normally without stopping the whole machine, and therefore the influence of wire breakage on the whole machine can be greatly reduced, and the yield and benefits are improved.

Description

technical field [0001] The invention relates to a wire break detection device for multi-strand wires on a multi-head wire take-up machine, which controls a corresponding motor to stop after the wire break is detected. Background technique [0002] The structure of the currently used disconnection detection device is as follows: Figure 4 As shown, it includes a base 1, a copper rod 2 arranged on the base 1, and a disconnection detection circuit. When it is working, when the broken wire hits the copper rod 2 back, the detection loop is closed, and the PLC can detect the broken wire and control the start and stop of the motor. But this kind of disconnection detection device can only detect the disconnection of a single strand, and for the disconnection detection of multiple strands, it is impossible to distinguish which one is broken, and it is impossible to control the start and stop of the corresponding motor. Contents of the invention [0003] The technical problem to be...

Problems solved by technology

However, this kind of broken wire detection device can only detect the broken wire of a single strand. For the broken wire detection of multi-strand wires, it is impossible to distinguish which wire is broken, and it is impossible to control the corresponding motor to start and stop.
