Abstract


This paper focuses on Looper drawing machine control principle , hardware configuration , PLC program and drawing software design ideas . On the basis of the original drawing machine system , to explore a more optimized looper drawing machine production line control system to improve the level of control of the system , the reliability of the system , improve production efficiency and reduce the amount of maintenance , there are good practical value and theoretical research significance . First, in the proposed new control scheme on the basis of analysis of the original drawing machine control system shortcomings . PROFIBUS fieldbus technology introduced based United PLC, inverter and touch screen control program , and on more than one motor high-speed , high-precision control link . Select the Siemens S7 -300 PLC , Siemens MicroMaster 440 inverter and TP170 touch screen to form a production line control system hardware systems . Second , analysis of the looper drawing machine production line control theory, focuses on the the looper roll role in the process of tuning , set by setting the value of the looper looper mechanical center position selected PID regulator to fix speed error . Finally, SETE7 PLC programming software to write brushed software , the completion of the inverter and the PLC communication speed of acquisition and operators as well as PID velocity correction process ; the Siemens the PROTOOL software design touch screen display , drawing varieties set operations automation the production process control , real-time closed-loop control , automatic counting meters and other functions , to further improve production efficiency , and provide a platform for raising the level of the production process .
