PLC Control System Design for Egg Carton Unloader
An egg carton unloader is a device used to feed eggs loaded in cartons to the clean egg production line, and mainly includes three major components: loaded carton conveying mechanism, carton unloading mechanism, and egg feeding platform. In this paper, based on the mechanical and pneumatic systems designed for the device, the Siemens S7-1200 PLC is selected for control system development for the egg carton unloader, distribution design and program control flow chart design for I/O point, realization of automation control of the carton conveying mechanism, carton unloading mechanism and egg feeding platform. It features high reliability and high cost effectiveness.
