Safety control method for fast revolution of flat machine

Abstract

The invention discloses a safety control method for fast revolution of a flat machine, which comprises the following steps: firstly, a coder of a servo motor of the machine head of the flat machine is simultaneously connected with a main control panel and a server, the servo motor is in control connection with the server, and the main control panel is in communication connection with the server; then, the main control panel obtains both the operation start point and the operation end point of each line before operation, and the maximum coder value which the operation of each line reaches through reading and analyzing design information of a product, then the main control panel is combined with the acceleration and deceleration performance control parameter to calculate the coder values corresponding to each deceleration position point and each acceleration position point; the main control panel sends the positions of each deceleration position point and each acceleration position point, the corresponding coder values and target speed to the server; finally, in the process of operation of each line, the server directly monitors the output value of the coder to enable the servo motor to operate at each deceleration position point and each acceleration position point according to destined coder values, so that optimal revolution control is realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent control of knitting and spinning machines, and relates to a safety control method for fast rotation of a flat knitting machine. Background technique [0002] During the knitting process of the flat knitting machine, each knitting line needs to be turned after reaching a certain characteristic point. The speed control of the flat knitting machine during the knitting process is directly related to the knitting efficiency and production safety of the flat knitting machine. [0003] At present, the rotation control method adopted by the main control board on the flat knitting machine is to calculate the farthest point that the machine head needs to reach, set a small speed value before reaching the farthest point, and then set a speed value according to the rotation position after reaching the farthest point. The speed value in the opposite direction of the series, so that near the farthest point,...

Problems solved by technology

[0005] The invention provides a safety control method for the fast rotation of the flat knitting machine, which solves the problems in the prior art that the main control board of the flat knitting machine monitors the encoder value, calculates it in real time, and sends it to the server to realize speed regulation, speed monitoring, calculation, and transmission. and effective delay, which eventually lead to the problem of slow reversing of the machine head; and the unreasonable limit control method, which leads to accidents caused by the machine head easily rushing out by inertia
