基于PLC的快递分拣系统

近年来，快递行业的订单量迅猛增涨，而快递分拣环节的机械化水平较低，主要采用人工分拣。人工分拣已无法满足快递业务的需求。为了提高快递分拣效率，根据分拣要求进行软硬件设计，利用可编程逻辑控制器（PLC）与液压系统设计一套快递自动分拣系统。快递分拣系统由触摸屏、PLC、传感器、电机、扫描相机以及液压缸等机构组成，触摸屏为西门子KTP700系列，PLC使用西门子1200系列中的S7-1215CPU。人机交互界面用西门子博图V15软件完成设计。液压系统完成快递的分拣推送任务和控制过程。本系统能自动识别不同区域的快递，完成连续、大批量地分拣业务，降低了劳动成本，进而提高了企业的整体效益。

Design of Express Sorting System Based on PLC

With the rapid increase in order volume of express industry in recent years, manual sorting has been unable to meet the needs of express business as the mechanization level of express sorting is low, while manual sorting is prevalent. In order to improve the efficiency of express sorting, software and hardware were designed according to the sorting requirements, and a set of express automatic sorting system was designed using programmable logic controller (PLC) and hydraulic system. The express sorting system was composed of the touch screen, PLC, sensors, motor, scanning camera and hydraulic cylinder and other components. The touch screen was Siemens KTP700 series, and PLC was S7-1215CPU in Siemens 1200 series. Siemens Botu V15 software was used to complete the design of human-computer interface. Hydraulic system was used to complete the express sorting push task and control process. This system can automatically identify the express delivery in different areas, complete the continuous and mass sorting business, reduce the labor cost, and improve the overall benefit of the enterprise.
