Design of Monitor and Control System for Adjustable Mandrel Conveyor

ABSTRACT

The design is based on industrial control configuration software MCGS and programmable controller unit adjustable mandrel conveyor monitoring system, the use of machine transport instead of the traditional manual feeding method, to achieve rapid and accurate hammer stem rod automatically transported. In the transmission process, the host computer monitoring system through automatic and manual control of the two ways to switch the hardware system and operation; monitoring interface real-time display mandrel from the box automatic feeding, belt conveyor, precision blanking and other operations; According to the different specifications of the mandrel, in the host computer interface to set the transmission speed, delivery time and other operating parameters; if the process of failure, will promptly sound and light alarm to remind the site staff to check to ensure safe operation.

The system hardware design mainly includes PLC selection, I/O address allocation, PLC hardware I/O wiring; system software design is to use GX Developer to complete the ladder programming and debugging; configuration interface design,including users The establishment of the window, the establishment of real-time database, the preparation of the script and the establishment of the main window. The monitoring system is composed of PLC and industrial control configuration software. The operation is simple and convenient, and the control accuracy is high. The system can realize the automatic and rapid transportation of the hammer handle rod, which can greatly improve the conveying efficiency and the subsequent grinding speed , Effectively reduce the labor intensity of workers, and fully guarantee the production and processing safe and reliable.
