【正文】 uses the programmable controller at present as the pneumatic system control device (PLC). The programmable foreword controller is take the microprocessor as a foundation, prehensive puter technology, the a utomatic control technology and the munication technology but develop one kind new, general automatic control device, in the practical application, the control system is very easy to realize. Is generally by is controlled the equipment the sequence of operation and the technological requirement, constitutes the labor step of condition table, forms the trapezoidal chart, again establishes the PLC instruction. The material transporting system moves the air cylinder, the replacement onset and retreat air cylinder by about, rises and falls the air cylinder, clamps the hand or the vacuum cup, the material block, the sensor, the column guide rail, the support, the 外文翻譯資料 9 foundation, the microswitch and so on is the hand either the vacuum cup may grip or hold the material block, the capture material part uses the clamp type and the adsorption type two forms, selects the different form, may plete the work piece separately the capture and the adsorption, adapts the different type material the hand to use the electromag to attract gathers with separates the way clamp the hand or the sucker in rises and falls the air cylinder under the function to be possible to reciprocate。 The pneumatic system electromagism cross valve uses the afflux board containerization, reduced has taken the space。 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。 therefore any manipulator satisfies after its condition namely starts the movement. Between various is parallel. The machinist is the multidegrees of freedom open the type series structure. But changes the system request speed high control area broad precision unceasingly in spatial and the time dynamics parameter along with its configuration high, the traditional single degree of freedom organization control technology is far cannot satisfy this kind of controlled member to be good because of the air operated machinist cancels much to the 外文翻譯資料 8 multistage localization control, the pursue target point pointing accuracy and multiple spindle at the same time cooperates weakly to have the foreword movement control, but little requests the high path precision, thus simplified to the control system request. The material mode of transport has the multipurpose function which may grasp may attract。s principle is: Full analysis work object (work piece) the work specificatio
