文档介绍：摘要
本文阐述了可编程控制器(以下简称PLC)从产生到现在,实现了接线逻辑到存储逻辑的飞跃;。其功能从弱到强,实现了逻辑控制到数字控制的进步。随着科技的是新月异的飞速发展,社会经济的发展步伐需要不断加快,更加需要现代化工业的不断进步。一系列自动化生产设备便出现在生产车间,提高了生产效率,提高了经济效益,带动了整个社会经济发展,故在此开展了“罐装机系统设计”的课题。下面介绍该系统设计的内容。
文中所述的PLC程序设计已经过多次的实验。按其生产步骤、稳定性等方面,所设计的PLC程序已验证其正确性了。该系统充分利用了学习中的可编程控制器(PLC)的多方面知识和方法,。本设计作为毕业设计题目,主要价值在于运用理论与实际相结合,虽然没有百分百的实现,但也不失这样的价值。如前所述,全球都需要高新科技,来带动整个经济的发展。自动罐装机是自动化生产技术的代表之一是必不可少的。这一控制系统的实现和应用,充分体现了PLC系统在工业的现场的应用,以及根于设计和不同的需求改变数据和状态,还可以使其应用的范围更加广泛,总之PLC在工业生产上起着很大的作用

ABSTRACT
The paper its describe design project of the pure water automatic can, system its mainly designs for automatic system of the product line. Following the principle that the bines with the practice, base on the principle of the thread of PLC controlling, on the premise of easuring and program the design, mend every project of systematic design process of whole automatic can to realize from the superficial to the deep. With the science and the technology developing at full speed of crescent, improve production efficiency, have increase economic efficiency, have driven the whole social economic development. So launched the subject that " the designed of Automatic Can System ". Now content that the introduction should be designed systematically.
The full text is divided into seven chapters. Chapter I describes the scope and application of the automatic canned functional significance. Chapter III described the Plc control system design of the basic principles, main contents, the general steps Chapter IV on the main power lines to the principles of ponents, characteristics and parameters and purchase. the design, Plc instructions table. profiles. Originally design as the graduation project topic, chief value lies in using the theory bine with reality, though there is no 100% realization, does not lose such value either. As noted previously, the whole world needs new and high technology, to drive the development of the whole economy. Automatic can automatic represe
