课 程 设 计 报 告生产线自动装箱的 PLC 控制设计班级： P11 电气 3 班 姓名： 学号： 2025 年 11 月 30 日摘要在现代化的工业生产中常常需要对产品进行计数和包装，假如这些繁杂的工作由人工完成的话不但效率低，而且劳动强度大，不适合现代化的生产需要。本文主要对基于生产线自动装箱的 PLC 控制系统进行了详细的分析。该系统有两个传送带，即包装箱传送带和产品传送带。包装箱传送带用来传送产品包装箱，其功能是把已经装满的包装箱运走，并用一只空箱来代替。为使空箱恰好对准产品传送带的末端，使产品刚好落入包装箱中，在包装箱传送带的中间装一光电传感器，用以检测包装箱是否到位。产品传送带将产品从生产车间传送到包装箱，当某一产品被送到传送带的末端，会自动落入包装箱内，并由另一传感器转换成计数脉冲。本控制系统具有精度高、成本低、抗干扰能力强、故障率低、操作维护简单等特点，具有良好的应用价值。 关键词 可编程控制器 自动装箱控制系统 传送带控制 AbstractIn the modern industrial production, often need to count and packaging, if these complex work completed by the artificial words not only low efficiency, and high labor intensity, production can not meet the needs of modernization. This article mainly has carried on the detailed analysis of the control system of the packing automatic production line based on PLC. The system has two conveyor belt, packing belt and conveyor belt. The package box conveyer belt is used to deliver the product packaging box, its function is to send box has been filled, and replaced by acontainer. Just to make empty at the end of conveyor belt products, make the product just fell into the packing box, aphotoelectric sensor in the middle package box conveyer belt, in order to check if package box in place. Product conveyor beltproducts from production to packaging box, when the end of a product is sent to the conveyor belt, will automatically fall into the packing box, and by another sensor is con...
