Coiling diameter period compensation method

Abstract

The invention discloses a coiling diameter period compensation method, which comprises the following steps of: setting a wire return rate based on the service life of a wire to ensure that the wire running length of each wire running period is greater than the wire return length; calculating a theoretical line loss length of the line when the current line running period is completed based on a preset line return rate; capturing in real time and calculating the actual line loss length of the line when the current line running period is completed based on the winding and unwinding positions; calculating a difference value between the actual line loss length and the theoretical line loss length to obtain a compensation value; and performing running line compensation in the next running line period by utilizing the calculated compensation value. According to the coil diameter period compensation method, the compensation value is introduced to compensate the wire consumption, so that the abraded wire is continuously recovered according to the pre-designed loss rate, and the monitoring and calibration of the wire consumption can be conveniently realized only through software programming.

Description

technical field [0001] The invention belongs to the technical field of winding diameter wire recovery, and in particular relates to a winding diameter periodic compensation method. Background technique [0002] Under certain application conditions, we hope that the non-stretchable rigid wire can be used repeatedly. Since the wire has a certain service life, the wear of the wire will affect the use effect, so the wire should be recycled when it is close to the service life of the wire. It is necessary to monitor the number of cycles of the line. For equipment that requires fixed ends and only uses a section of reciprocating motion, it is cumbersome to record the number of cycles of the line and replace the line after the number is exceeded. In the prior art, a large amount of wire is usually wound on the first round roller. When it needs to be used, the wire will be continuously released with the rotation of the first round roller, and the other end of the wire will be taken ...

[0002] Under certain application conditions, we hope that the non-stretchable rigid wire can be used repeatedly. Since the wire has a certain service life, the wear of the wire will affect the use effect, so the wire should be recycled when it is close to the service life of the wire. It is necessary to monitor the number of cycles of the line. For equipment that requires fixed ends and only uses a section of reciprocating motion, it is cumbersome to record the number of cycles of the line and replace the line after the number of times is exceeded.

In the prior art, a large amount of wire is usually wound on the first round roller. When it needs to be used, the wire will be continuously released with the rotation of the first round roller, and the other end of the wire will be taken up by the second round roller. Therefore, a usable line segment is formed between the two round rollers. After a certain number of uses, the thread is uniformly recovered on the second round roller, and a new line is released from the first round roller between the two round rollers, which is extremely It greatly saves the time of changing the thread, and only needs to record the number of times the thread is recycled between the two round rollers. The reciprocating movement of the thread between the two round rollers includes the thread running process and the thread returning process. The thread returning process is a thread running cycle, the length experienced by the thread in the thread running process is the thread running length, and the length experienced in the thread returning process is the thread returning length, that is, the usage of the thread can be monitored by counting the number of cycles of the thread running cycle, However, due to the influence of factors such as the wire slipping on the round rollers during the actual operation, it is impossible to control the reciprocating movement of the wire between the two round rollers every time according to the predetermined loop length, so that the wire cannot be recovered accurately according to the predetermined requirements.
