摘要
 此次毕业设计，主要完成自动送料系统——送料小车控制设计，以及切割系统的控制设计。
 第一章介绍了选题背景意义，研究的内容及方向。中国开放进程不断加强，经济快速增长，与国外企业的外贸合作越来越多。因中国拥有丰富的劳动力资源，工资低廉，因此来自国外的外贸订单源源不断。目前为止，中国俨然已成为世界制造业的“中加工厂”。特别是沿海开放城市，更遍布各种加工企业。    然而，随着沿海城市的地价与人工的不断飙升，造成企业生产成本大幅增加，加之外来工每年逐渐减少，各大工厂企业普遍缺少生产工人，严重制约了加工企业的发展。
 鉴于此，加速企业自动化进程显得尤为必要。提高自动化程度既解决了工人紧缺的问题，也能缩短工期，用同样的时间做出更多的产品。
 第二章利用PLC可编程控制系统，结合闪烁电路，起保停电路，延时电路，结合FXPGWIN软件，完成对送料小车控制系统的设计。
 第三章介绍了切割系统的电路设计。切割部分是由一系列继电器配合感应开关及气缸，机械部件组成，主要原理是材料由振动盘送到指定位置后，感应开关感应，继电器将信号传到气缸，气缸推动机械部件进行下一步加工。
 用继电器结合接近开关，再结合电磁阀以及气动传动，达到自动循环切割的目的。

Abstract
 The graduation project, completed for automatic feeding system - vibration plate design, and cutting system circuit design.     The first chapter introduces the topics and historical context, the content and direction.Continuously strengthen the process of China's opening up and rapid economic growth, foreign trade cooperation with foreign enterprises more and more. Because China has abundant labor resources, low wages, so endless trade orders from abroad. So far, China has become an industry in the world "in the factory." Particularly in the coastal open city, but all sorts of processing enterprises.       However, with the coastal cities of soaring land and labor, resulting in a substantial increase in production costs, coupled with the gradual reduction of foreign workers each year, major factories and enterprises in general lack of production workers, seriously hampered the development of processing enterprises.     In view of this, speed up the automation process is particularly necessary. Increased automation will resolve the issue of shortage of workers, but also shorten the construction period, with the same amount of time to make more products.     Chapter II using PLC programmable control system, combined with flash circuit, from Paul blackout Road, delay circuit, combined with FXPGWIN software, complete car control on the feed system.The third chapter describes the circuit design of cutting systems. Cutting part of a series of relay switches and the cylinder with the sensors, composed of mechanical parts, the main principle is that materials delivered to the specified location by the vibrating plate, the sensor switch sensor, relay the signals to the cylinder, the cylinder to the next step to promote the mechanical components processing.Combination of proximity switches with relays, combined with electromagnetic valve and pneumatic drive, to achieve the purpose of automatic cutting cycle.
