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,如果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研究。该系统有一个机械手和两个传送带,即运物机械手,包装箱传送带和产品传送带。运物机械手用来转移饮料瓶,即把产品传送带上的饮料送到包装箱传送带的饮料箱中。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。为使空箱恰好对准机械手松开端,使饮料瓶装进包装箱中,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。为使产品传送带将产品从生产车间传送到合适位置,在产品传送带的中间也装有一光电传感器。当产品被送到传送带的末端,会自动停止并由机械手将其送到包装箱中。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。

Abstract
Often need to carry out counting and package on the product in the commercial run being modernized, not only the inefficient, moreover intensity of labour working from the words that the manpower accomplishes if these are complicated and overloaded is big , the childbirth being unfit to be modernized needs. Detailed research the main body of a book has been carried out on the PLC navar enchasing owing to production line automation mainly. Be system's turn to have two conveyer belts , be package box conveyer belt and product conveyer belt. The package box conveyer belt is used to deliver the product package box , whose function is that the package box luck already filling to full is leaked , is uses one to replace to come empty space box and. End being to make the empty space box aim at the product conveyer belt fitly, just the drop-in package box is hit by the messenger product, before package box conveyer belt centre install one photoelectricity sensor, in order to check if package box arrive at a place. And the product conveyer belt transmits a product from producing a workshop to package box , pawn some one products deliver to the conveyer belt end , the meeting automation drop-in package box inner, change from another sensor becoming counting pulse. Navar has accuracy height , the low , anti-interference ability of cost is strong , the malfunction leads a characteristic low , operation upkeep waits for simplely, have fine application value.
Key words : programming controller Automation encasement navar The conveyer belt is controlled
