Carbon fiber warp knitting machine multi-axis partition linkage control system and method

Abstract

The invention relates to a system and a method for multi-shaft partitioning coordinated control of a carbon fiber warp knitting machine. The system comprises a real-time high-speed Power Link bus, an X2X communication bus, a man-machine operating device connecting the real-time high-speed Power Link bus and the X2X communication bus through a signal converter, an encoder installed on a main shaft of the carbon fiber warp knitting machine, and a digital quantity input module generating reference clock and connected with the X2X communication bus. The encoder is connected with the digital quantity input module to transmit signals. The real-time high-speed Power Link bus is connected in parallel with a main time zone module, a first weft thread time zone module, a second weft thread time zone module, and a third weft thread time zone module. The real-time high-speed Power Link bus is connected with 28 independently controlled motion shafts and controls the motion shafts. Driven by the reference clock, the 28 shafts coordinately work respectively according to respective motion trail and mathematic model, thereby forming an organic whole, and achieving complex operation of weft threading and knitting, ensuring precision of warp knitting, and improving sensitivity of equipment operation.

Description

technical field [0001] The invention relates to the technical field of textile warp knitting control, in particular to a multi-axis partition linkage control system and method for a carbon fiber warp knitting machine. Background technique [0002] The carbon fiber multi-axial warp knitting machine is a very complex linkage system composed of 29 independently controlled motion axes and more than 300 control points. The independence of each of them, their motion axes work in harmony according to their own motion trajectories and mathematical models, and complete the weft laying and weaving of carbon fibers. An important feature of the carbon fiber multiaxial warp knitting machine is that the weft laying width and weft laying angle of the three weft laying systems can be different. In this way, the 7 control axes in the same weft laying system move according to certain rules, but because the weft laying width and weft laying angle are different, the three weft laying systems a...

Problems solved by technology

In this way, the 7 control axes in the same weft laying system move according to certain rules, but because the weft laying width and weft laying angle are different, the three weft laying systems are independent and move independently, and it is even difficult to observe the relationship between them

Such a large and complex control system is difficult to achieve with traditional unified clock control, and foreign countries have blocked the control technology of carbon fiber multiaxial warp knitting machines. Therefore, it is necessary to invent new control methods to adapt to the large and Complex and changeable linkage system
