摘要
基于特种工业缝纫机应用范围的拓展,性能不断提升,要求自动缝制单元除有缝纫机自动缝制的功能外,同时兼有自动送料、自动折料、自动取料、自动定位功能。本文采用电控系统+外置可编程PLC实现要求功能,电控系统可采用花样缝纫机的电控系统,外置PLC采用西门子公司的S7-200PLC,系统和PLC间通过通信实现协调控制。通过PLC外部电路和时序控制,实现自动缝制单元中自动送料等缝纫过程中的特殊过程。
Because of the application of special industrial sewing machine developing, and as its performance continuously improve. Require automatic sewing unit apart from the automatic sewing function of sewing machine, it has other functions, such as automatic feed, automatic folding material, automatic fetching and automatic positioning. In this paper, using electronic control system ＋ the outer programmable PLC to realize requirement function. Electric control system can use pattern of sewing machine control system, external PLC can use S7-200PLC of the Siemens, then through the communication between system and PLC to realize coordination control. Through PLC external circuit and the sequential control to realize special process in sewing process such as automatic feed.
