And PLC control are the most commonly used industrial automatic control method, because of its easy to control, able to withstand harsh environment, therefore, is superior to the single chip microcomputer control in industry. PLC will be the traditional relay control technology, computer technology and communication technology, designed specifically for industrial control, with strong function, general flexible, high reliability, strong adaptability to environment, simple programming and easy to use and a series of advantages such as small volume, light weight, so more and more widely used in industry. Conveying line, occupied the main position in the factory, it is related to whether can normal production, so the material conveyor line automation control research has become very necessary. Automated control can not only make labor freed a heavier physical labor can also make the production process control more accurate. This article mainly tells the PLC application in material handling, using programmable controller (PLC), design of high efficiency, low cost of automatic material handling system. Is given priority to with PLC controller, combined with pneumatic device, sensing technology, posit
