ABSTRACT
This is a paper on the structure and control of the chain continuous transmission line, in this paper, the main transmission line structure and PLC and inverter control is an in-depth research and design. This design mainly adopts the mechanical structure design of the chain transmission line, AC drive speed control based on the frequency converter and the computer control system based on PLC (programmable controller). The design of the main working principle is: transporting through the PLC control inverter starting motor, material in the transmission process board, pressure electrical sensor detecting material conv eying quality, speed sensor detects a need for signal transmission speed regulation after the control signal to the PLC to control the inverter; at the end of the displacement sensor detecting the material arrives, and ultimately the purpose of conveying material. In this paper, detailed introduces the chain sprocket transmission device of the mechanical structure, control system hardware and software composition, systematically using I / O distribution diagram, the software flow chart and the ladder chart programming to describe the simulation of the operation of the system.
