Abstract: Along with the rapid development of science and technology, especially in the fields of electrical–electronic engineering and automatic control, automation systems have been increasingly and widely applied in industrial production in order to improve productivity, accuracy, and operational stability. Many traditional manual processes have gradually been replaced by programmable control systems, among which the product classification system based on weight is a typical application. The classification system is responsible for weighing products as they enter the system (the load cell sends signals to the PLC to verify the product weight) and sorting them into carton boxes. Subsequently, conveyor belts transport the cartons to the carton packing system for closing and sealing the box lids.
Keywords: load cell, PLC, the classification system, sorting, carton packing.
