【導讀】氣動即采用氣泵和氣閥控制氣流，直接控制氣壓和流量，使得空氣發(fā)生振動。術于一體的一種新型工業(yè)控制系統(tǒng)。PLC采用了典型的計算機結構，主要包括。如果把PLC看作一個系統(tǒng)，該系。測的信號均作為PLC的輸入變量，它們經PLC外部端子輸入到內部寄存器中，單指令,形象直觀，是基于現場總線技術、完全開放，采用先進的軟硬件技術。其中重要的一部分。在這次調查中，超過半數的人在未來的12個月中將擴大其。在這次300個人參與的調查中，大部分的PLC都用于機械控制，過程控制緊隨其后，然后是運動控制、批量控制和診斷。的疲勞，出現錯誤?？焖佟蚀_、方便，大大的減輕勞動強度，提高生產的自動化程度。這種有規(guī)律的運動，采用PLC來進行控制，可以方便的實現。PLC的程序運行方式是循環(huán)掃描方式，而非。板集裝方式，減少了占用空間；PLC控制具有單步、自動等多種工作方式。氣動系統(tǒng)的應用，引起了世界各國產業(yè)界的普遍重視。能，在PLC控制下可實現單步、自動等多種工作方式。

　　

【正文】 olumn guide rail moves。 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。 Continuously: After presses down “the start” the button, clamps the hand to start from the zero point position continuously to carry out the transporting transporting s ystem realization movement: The drop stresses the material rise right lateral to drop the loose material to rise again the left shift to push the material again to enter pushes the material to draw this system, we only realize a material cyclic action, therefore returns to the zero point after the manipulator, must drive back the homing position the realize the single acting under the PLC control, 外文翻譯資料 10 act continuously the after the system the electricity, according to turns the choice through revolving is the single acting or the gearing, if is the single acting carries out the single acting procedure, otherwise carries out the gearing acting working: To clamps hand each movement using the button alone to carry on the : Presses down the start button, clamps the hand to start from the zero point, according to the working procedure autocycle work, until presses down the pause button, clamps the hand after to plete last cyclical the work, returns to the zero point, autostop. Can realize the material autocycle transporting based on the PLC control material transporting system both may use clamps the hand clamp material, and may use the vacuum cup adsorption material, has the multiple functions function。 The pneumatic system electromagism cross valve uses the afflux board containerization, reduced has taken the space。 May realize the single acting and the gearing two execution way under the PLC control, pletes the material the transporting. Regarding small and mediumsized enterprise, as a result of fund and technical limit, not impossible disposable equipment integrity control system, like DCS PLC is the general controller. Standard building block system hardware architecture, modular software according to the control area be possible to be possible small, to be possible greatly Jan Kefan, to use the general IBM labor to control machine or the patible machine, the necessary mercialization on position monitoring software package or hangs on the corresponding workstation, realizes functions and so on equipment operation, return route control, picture demonstration, nimble simple, saves the , as the foundation process control system may constitute one kind take PLC the plete product which is advantageous for the user to organize voluntarily.
