Abstract:In order to improve the sorting efficiency and accuracy of traditional express sorting system, a set of swing wheel express sorter control system is designed. According to the number information scanned by the front-end code scanning system, the system obtains the pier information corre-sponding to the package number address, and manages the packages on the sorting line in the form of queue. The sorter detects the cargo position on the sorting line through the infrared tube, obtains the information of the corresponding packages stored in the queue according to the count value, and determines the package outlet according to the sorting information. The experimental results show that the control mode of queue mode, double infrared detection and variable speed double swing angle has high sorting accuracy and efficiency, up to more than 6000 pieces per hour. The swing wheel express sorting system can significantly improve the efficiency and accuracy of parcel sorting, which is of great significance to reduce the parcel processing time and save the logistics cost.
