气动打包工序的电气设计
摘要：随着社会经济水平的不断发展，生活水平的不断提高和生活节奏的加快，各个地区之间的生活食品和生活用品的流通量越来越大，导致人们生活中的物件打包的需求量越来越旺。打包机在工业生产中应用非常广泛，实现自动控制的包装系统能够极大地提高生产效率和产品质量。首先只有进行打包物品才能运输，其次打包的效率决定了输出物品的量。
PLC在目前的工业控制应用中十分广泛，它具有响应快、精度高、集成化程度高、编程简单的特点。本课题充分研究了电气控制系统中主要元器件的工作原理。本文在充分学习PLC控制系统和打包机的工作原理的前提下，结合继电器控制系统和气动系统，设计了由PLC控制的自动打包机的电气设计。同时为了充分掌握继电器系统和PLC控制系统的区别，另外设计了一个继电器系统实现的自动打包机，文中对两个系统做了简单的理论上的比较，加深了对这两个系统的了解。
文章从自动打包机的控制流程出发，结合要求，设计了整体的控制方案。再从原理图、选型、编程方面落实到实际工作中去，汇总基于三菱FX3GA的PLC方案和继电器方案，设计出了符合要求的自动打包机。

The Electrical Design of Packaging Machine
Abstract: With the continuous development of social and economic level, the continuous improvement of living standards and the pace of life is speeding up, the flow between the various regions of the living food and daily necessities getting more and more frequency, this leads to more and more prosperous in people’s living needs to be packaged. The package machine nowadays is widely used in industrial production, and the automatic control of the packaging system can greatly improve the production efficiency and product quality. Firstly, you need to package the goods before you send it to somewhere else. Secondly, the efficiency of packaging machine determines the amount of output goods.
PLC is very widely used in the current industrial control system, it has features like fast response, high precision, high degree of integration, programming simple. This paper fully studies the working principle of the main components in the basic electrical control system. In this paper, under the premise of fully studying the working principle of PLC control system and packaging machine, combined with the relay control system and pneumatic system, I complete the design of PLC-controlled automatic packaging machine electrical system. At the same time, in order to fully grasp the differences between relay system and PLC control system, I also designed a relay system to achieve the automatic packaging machine. Deepen on the understanding of these two systems, I made a simple theoretical comparison of the two systems.
This article start from the automatic control process of packaging machine, combined with the requirements, I designed of the overall control solution first. And then, I did the schematic diagram, main components selection, programming. This design is based on the Mitsubishi FX3GA PLC programmer and relay components. And then it comes to meet the requirements of the automatic packaging machine.
Key words: PLC ；relay-system ；packaging machine
