摘要伴随着社会的进步，科技的发展，市场竞争日益激烈，各个公司不得不大力发展技术，以增加市场竞争力，这种现象在那些需要进行物料识别与存储的公司尤为明显，在以往的生产活动中，都是采用人工的手段来进行工作，这不仅降低了生产效率，而且大大增加了生产成本种种现象都表明这些公司必须改变生产结构，所以物料自动识别缓冲控制系统成了这些企业的首选。对于之前的一些问题，物料自动识别缓冲控制系统都可以很好的解决，这一系统可以自动运行，降低运营成本，减少了人工错误，增加了生产效率。33251

本文主要讲述货料自动识别缓冲控制系统的设计，该系统以PLC为控制核心，结合传感器技术、气动技术等技术辅助，从而使系统可以完成货料识别、自动入库及自动出库的动作。本系统有着精确度高、响应速度快、便于控制等优点。
因为随着生产要求的不同，PLC的程序设计也会有很大的变化，而且考虑到个人能力的不足以及时间的有限，因此本次程序的设计中去掉了一些不是必须的功能，从而尽力做好货料自动识别缓冲控制系统的基本功能即：有货料时传送带自动运行功能、传感器的自动识别功能、气动手的货料自动入库功能、库装满时的自动出库功能。

Abstract
Along with social progress, technological development, market competition is becoming increasingly fierce,each company had to develop the technology, in order to increase market competitiveness, this kind of phenomenon in those who need to identify the material and storage company, in the production activities of the past, are using artificial means to work, this not only reduces the production efficiency, and greatly increased the cost of production of various phenomena show that these companies must change the structure of production, so the material automatically identify the buffer control system into the enterprise's first choice. For some of the problems before, automatic identification of material buffer control system can be well solved, the system can be run automatically, reduce operating costs, reduce the artificial error, increase the production efficiency.
This article mainly tells the goods material design of the control system of automatic identification buffer, the system uses PLC as the control core, combined with the sensor technology, pneumatic technology and so on technical support, so that the system can complete the goods identification, automatic inbound and outbound movements. This system has high precision, fast response, easy to control, etc.
Because as the requirement of production, a PLC program design also can make a big change, but also to the lack of personal ability as well as the time is limited, so I in the design of the program to remove the function of some not necessary, and try my best to learn the basic function of the automatic identification of goods material buffer control system: the conveyor belt when available to run automatically, automatic identification of sensor, gas to material goods automatic warehousing function, the library automated outbound when full function.
