Head-reconfigurable modular control system for flat knitting machines

Abstract

The invention relates to a head-reconfigurable modular control system for flat knitting machines. The system is characterized by comprising a group or plural groups of control units, each group of control units comprises four triangular needle-selecting stitch circuit modules and a yarn-feeder sinker circuit module which are subjected to communication connection through a CAN (controller area network) bus. The technical scheme of the invention is as follows: a modular reconfigurable system is composed of triangular needle-selecting stitch circuit modules and a yarn-feeder sinker circuit module based on a looping mechanism for the flat knitting machines, so that the function modular control and reconfiguration of the control system according to the looping number of a head are realized, and thus the head-reconfigurable modular control system has extremely good scalability. A circuit module board is connected with the main control board of a flat knitting machine through a CAN bus network, so that the real-time performance, stability and reliability of communication under the condition that a head is running at a high speed are improved, and the yield and production efficiency of fabrics woven by the flat knitting machine are improved.

Description

technical field [0001] The invention relates to a reconfigurable modular control system for a flat knitting machine head. Background technique [0002] Computerized flat knitting machine head system is the core component of computerized flat knitting knitting production. Its main work is needle track design and yarn feeding and yarn feeding control to realize the knitting function of knitting. The stability and reliability of its control system are related to whether the entire knitting and looping process is successfully completed, and its overall performance directly affects the knitting efficiency and fabric quality of the flat knitting machine. In recent years, with the continuous development of the computerized flat knitting machine industry, the flat knitting efficiency of the single knitting head system is low, which can no longer meet the needs of high-efficiency and energy-saving production. Therefore, the double knitting head system and the three knitting head syst...

Problems solved by technology

In recent years, with the continuous development of the computerized flat knitting machine industry, the flat knitting efficiency of the single knitting head system is low, which can no longer meet the needs of high-efficiency and energy-saving production. Therefore, the double knitting head system and the three knitting head system have been Into the industry development trend

However, the current computerized flat knitting machine head control system is often customized according to the number of loops into a single knitting head system, a double knitting head system, a three-knitting head system, and a control circuit board for a multi-knitting head system. , and each control circuit board is different, does not have compatibility, cannot be universally used on different knitting head system machines, has poor modularization and scalability, and the stability and reliability of the system cannot be guaranteed
