摘要:随着时代的发展,当今的技术也日趋完善、竞争愈演愈烈,单靠人工的操作已不能满足于目前的制造业前景,也无法保证更高质量的要求和高新技术企业的形象。人们在生产实践中看到,自动化给人们带来了极大的便利和产品质量上的保证,同时也减轻了人员的劳动强度,减少了人员上的编制。在许多复杂的生产过程中难以实现的目标控制、整体优化、最佳决策等,熟练的操作工、技术人员或专家、管理者却能够容易判断和操作,可以获得满意的效果。可编程控制器是一种为工业控制所设计的专用计算机,在各种自动控制系统中有着广泛的应用。利用PLC对老设备进行技术改造,是工厂提高设备利用率,提高产品质量和产量,减轻工人劳动强度的有效途径。本次课题内容为冷饮生产线PLC控制的设计。主要目的是解决目前冷饮生产线控制中所存在的一些问题,合理的利用PLC的硬件资源和软件资源,做到控制需应尽量简单,便于理解,并有一定的规律性一杯能与不同控制的要求。9814

Abstract:Along with the development of the ages, the technique thatis nowadays is also gradually perfect, the competition playsmore more strong; the operation that list depends the artificial has already can't satisfied with the current manufacturing industry foreground, also can't guarantee the request of the higher quantity and high new the image of the technique business enterprise.The people see in produce practice, automate brought the tremendous convenience and the product quantities for people up of assurance, also eased the personnel's labor strength, reduce the establishment on the personnel. The target control of the hard realization in many complicated production lines, whole and excellent turn, the best decision etc., well-trained operation work, technical personnel or expert, governor but can judge and operate easily, can acquire the satisfied result.Programming  logic controleis a kind of  is  an industry control design of appropriation calculator,have an extensive application in various auto control system.make use of plc to carry on the technique reformation to the old equipments,is the factory exaltation equipments utilization,raise the product quality and yield,ease the valid path that the work labors strength.major purpose is solution exist in present Cold drink production line control some problems. Use software resource and the hardware resource of plc reasonably. Raise the safe reliability of elevator and the flexibility of operation,reduce the input export port of plc. Use the easier control program of various instructions fully. Accomplish control program should as far as possible simple.
