And satisfies the system function request and the environmental condition。 In under the replacement onset and retreat air cylinder function the material block back initial position, for the next action cycle preparation, realizes the system can realize a material in plane the kneading board to install in the electrically controlled box, is separates with the test installation main PLC programmable controller, the solenoid valve, the vacuum generator and so on lays aside in the electrically controlled box. About the material transporting system has moves, reciprocated and to the material clamp and the relaxation, pushes the material onset and retreat function, may realize on foot, and so on automatically under the PLC control many kinds of moreover, the material is clamped the hand transporting pletes, for satisfies continuously acts the need, but also must ship this material the zero point position, will supply the next time to transport the system may plete each working is as foot: May realize the rise, the drop, the left shift, the right lateral, the clamp, the relaxation, pushes the material to enter, to push the material to draw back and so on eight kind of spots to move the operation。 The PLC control has, is on foot automatic and so on the many kinds of work way. Because the pneumatic actuator has is angry the source easy to operate, does not pollute the environment, the movement nimbly rapid, the job safety reliable, the operation service is simple. And is suitable for under the adverse circumstance characteristic and so on work, thus in the ramming processing, casts and the pression casting and so on virulent or the high temperature environment is mean industry, on the engine bed, the yummy treats, the measuring appliance and in the light industry profession small work and so on ponents transportation and automatic assembly,
