The batching system adopts dual CPU to form a redundant system, and the STEP7MicroWin V4.0SP6 programming software provided by Siemens is used as the man-machine interface to write debugging programs and download programs. The PC and PLC experimental machine are connected by a PC/PPI cable for communication, and the corresponding parameters are set.
Weighing and mixing machine through PLC to control the frequency converter, so that the speed motor drives the metering screw according to the set speed running down the material. The whole weighing and dosing system can be divided into small material weighing, large material weighing and micro material weighing. It adopts the way of uniform speed feeding, and the way of decreasing speed feeding is adopted in the low speed stage.
The automatic sorting machine is fed into the sorting control system through barcode scanning, color code scanning, keyboard input, weight detection, voice recognition, height detection and shape recognition, etc., and decides which sorting channel the commodities will enter according to the weight signal judgment.
