1. Scope of supply: Engineering design, manufacture, installation and commissioning of 140 horsepower mechanized conveyor system for large wheel dragging and painting line.

2, project introduction

The system is mainly composed of process chain (slow chain) and conveyor chain (fast chain) conveying system, which completes the operations of upper part, shielding, degreasing, water washing, cooling, robot spraying, topcoat drying and off-line. The transfer of the trolley group between the process chain (slow chain) and the conveyor chain (fast chain) is adopted to capture the Manchester United pusher switch to control the stop to prevent the car from happening. Mechanical and electrical linkage protection devices are set up during the transmission process to ensure that the accumulation trolleys are normally delivered according to the production tact. The control system mainly controls the process chain (slow chain) and the conveyor chain (fast chain) and the shifting elevator. It adopts SIEMNS series PLC and distributed I/O modules. The CPU has an Ethernet interface, which can upload the operation status of the air transportation system to The remote control room is monitored remotely. The control panel is equipped with a touch screen to display the errors and conveying process lines of the control system during operation. The control system uses fieldbus and the field control equipment uses distributed I/O control technology. The process chain and the shifting elevator adopt the frequency conversion control technology. With the SIEMENS STEP7 software and the PROFIBUS bus, the distributed I/O modules can be configured and parameterized to test and diagnose the entire network.
