Fully-mechanized circular knitting machine control system

Abstract

The invention discloses a fully-mechanized circular knitting machine control system which comprises a man-machine interaction unit, a real-time control unit and a mechanism executing unit, wherein the man-machine interaction unit is connected with the real-time control unit by adopting a parallel bus; the real-time control unit and the mechanism executing unit respectively realize data communication of density motor regulation control and control of various kinds of air valves by adopting a multi-path RS 485 bus and a multi-node CAN bus; the man-machine interaction unit is used for displaying state information of the fully-mechanized circular knitting machine control system, editing, storing and analyzing pattern files, editing system control parameters, and testing actions of all functional parts; the real-time control unit is used for reading process action information in a data conversion unit through the parallel bus, and storing the process action information in an external expanded memory of the real-time control unit; and the mechanism executing unit is used for controlling the action of a needle selector, density regulation action and actions of various kinds of air valves. The fully-mechanized circular knitting machine control system has the advantages of being large in pattern weaving range, being high in replacement speed, shortening the design period of products, being high in weaving speed, increasing the production efficiency and ensuring the reliability of system production.

Description

technical field [0001] The invention relates to a control system of a circular weft machine. Background technique [0002] Computerized circular knitting machines are widely used in the knitting industry, and its control system is mainly composed of computerized pattern preparation system and real-time control system. Compared with manual weaving or relying on simple motor-driven methods, the computerized circular knitting machine can reduce the labor intensity of the operator, and can meet the processing needs of various raw materials, realize automatic production, and reduce production costs. [0003] However, the reliability of the ordinary computerized circular weft machine control system is not high, and the pattern range is small, the speed of pattern replacement is slow, the product design cycle is long, and the weaving speed is low, resulting in low production efficiency. Contents of the invention [0004] In order to overcome the shortcomings of the existing comp...
