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.
Key words: PLC Ladder Automatic Cutting System Relay
