Flat knitting machine needle selector detection system

Abstract

The invention discloses a flat knitting machine needle detector detection system which comprises a man-machine operation control box and at least one set of needle selector detecting mechanism. An action position detecting mechanism detects the parameters of a needle selector. The man-machine operation control box is used for displaying output and touch input data. The human-machine operation control box converts the touch input data into an instruction and sends the instruction to a control detection board. Compared with the prior art, the system provided by the invention changes the existinguse of a flat knitting machine system to perform needle selector detection, and carries out closed-loop detection on the position and movement of the needle selector. The whole tooling is small in size and convenient to install. The system has the advantages that 1 the needle selector detection method has the advantages of reliability and science; 2 closed-loop detection is carried out on the position of the needle selector to solve the problem of jitter in the swinging action of the needle selector; and 3 the response speed of the needle selector is detected, and the problems of delay of theneedle selector swing and response index quantization are solved.

Description

【Technical field】 [0001] The invention relates to the technical field of flat knitting machine accessories, in particular to a detection system for a needle selector of a flat knitting machine. 【Background technique】 [0002] The flat knitting machine is an automatic machine with high technical content in the knitting machine industry. It integrates computer digital control, electronic drive, mechanical design and other technologies as a whole. The needle selector is a transducer that sequentially drives the needle selection mechanism according to the electrical signal combined by the fabric pattern, and is the actuator used by the flat knitting machine control system to implement needle selection control. [0003] In the prior art, the needle selector of the flat knitting machine relies entirely on the flat knitting machine system to realize the back and forth swing action, and does not perform closed-loop detection of the position of the cutter head, including the response...

AI Technical Summary

Problems solved by technology

This type uses a flat knitting machine system for needle selector detection. The whole system is relatively large, and the open parameter is only one drive pulse width value. If you want to run the response speed, you can only use different test patterns for testing. It increases the difficulty and workload of the tester, and at the same time, it is impossible to detect and quantify the needle selector
