Automatic control system for metal binding machine and control method

Abstract

The invention relates to an automatic control system for a metal binding machine and a control method. The metal binding machine is a steel belt binding machine; a mechanical system comprises a belt distributor, a guiding device, a leveling machine, a moving rack, a binding machine head and a guiding chute which are arranged along a steel belt conveying path; the control system comprises an electrical control system and a pneumatic control system; the electrical control system comprises a master controller as well as a touch screen, a signal detection unit, a speed control unit, a pneumatic control unit and an emergency stop unit which are connected with the master controller respectively; and the pneumatic control system comprises an air compression station, an air compressor and a pneumatic valve stand. With the system and the method, programmable logic controller (PLC) procedure and relay logic combined control and alternating-current variable-frequency control are adopted, whole-process automatic control including belt conveying, firm grasping, belt winding, tightening, buckling, cutting and the like is realized, real-time monitoring of the action process and efficient and automatic binding and packaging are realized, and the automation degree and the use performance of the metal binding machine are greatly improved.

Description

technical field [0001] The invention relates to the technical field of metal binding machines, in particular to a comprehensive automatic control system and control method for metal binding machines that combine electrical automatic control and pneumatic control. Background technique [0002] Fully automatic metal strapping machine is an important equipment on the continuous rolling packaging line of modern steel production enterprises. Its performance directly affects the packaging quality. The overall packaging quality of my country's strapping production line is not high, and many companies are still using semi-automatic or manual packaging equipment. Most of the electrical control parts are realized by the pull-in of relay contacts, which has defects such as high failure rate and large maintenance. The production efficiency is low, the labor resources are wasted, the packaging control accuracy is not high, and the degree of automation of bundling is far from meeting the n...

AI Technical Summary

Problems solved by technology

In order to solve the technical problem that the packaging control accuracy and production efficiency cannot be balanced, and realize the automatic control of the strapping process, it is imperative to apply the new technology solution of pneumatic and electrical automatic integrated control to the strapping machine.
