附件2：外文原文Air operated moves the carrier vehicle and the PLC controlAir operated namely uses the air pump and the air valve control air current, the positive governing barometric pressure and the current capacity, enable the air to have the vibration.The programmable controller (PLC) is taken the microprocessor as the core, collection computer technology, the automated control technology in a body one new industry control system. PLC has used the model computer structure, mainly includes CPU, RAM, ROM and the input/ Output connection electric circuit and so on. If regards as PLC a system, this system is composed by the input variable -PLC- output variable, the exterior each kind of switching signal, the simulated signal, the sensor examine the signal took PLC the input variable, they input after the PLC exterior post to the internal register in, after the PLC interior logic operation or other each kind of operation, processing delivers the output terminal, they are the PLC output variable, carries on each kind of control by these output variables to the auxiliary equipment.The PLC control system adopts generally easy to understand and to grasp trapezoidal chart language and face industry control simple instruction. The image is direct-viewing, is based on the field bus technology, opens completely, and uses the advanced software and hardware technology. The PLC control has the structure simply nimble, the anti-jamming ability strong, safe reliable, installs the convenience, the failure rate lowly, the maintenance is simple, large scale saves the use cost the characteristic, can satisfy each kind of center small scale process control, the smooth logic control and the data acquisition duty demand, widely has used in gradually in the industry control system, including domain and so on metallurgy, mining industry, machinery, light industry, has provided the powerful tool for the industrial automation.The control engineering in the near future to will use in the logical equipment which programmed the process and the machinery controls carrying on an investigation, although the computer and computer technology already provided the infinite control for each kind of control to be possible, but PLC still was a important part. In this investigation, it will surpass half number of people to expand its PLC in the future 12 months the investment. It will surpass 40% person in the future investment many in the past 12 months. The PLC application scope is extremely widespread. In this 300 individual participation investigation, majority of PLC all uses in the machinery control, the process control follows closely after that, then is the movement control, the batch control and the diagnosis. The majority uses in directly the factory level (54%), uses in OEM is 25%, two all is 17%.In the industrial production assembly line, must move frequently the transmission belt A on goods to conveyer belt B on. If direct artificially is engaged in this kind of duplicated work, arid, tasteless also labor intensity big, is easy to cause operates worker's weariness, appears the mistake. But uses the air operated manipulator carries on the transporting according to the stipulation movement and the rule, may achieve fast, accurate, is convenient, big reduces the labor intensity, enhances the production the automat city. Air operated manipulator this kind of orderly movement, uses PLC to carry on the control, and may facilitate realization.The robot sets an example the integration of machinery intelligence equipment. Flows in the automated system in the manufacture and the thing to act the strong character. But the standard industry robot only is has certain degrees of freedom an intelligent electromechanical device. Isolation robot in the actual operating mode is not any application value. Only then according to factor and so on work content, work piece form, quality, contour characteristic and size matches to the robot by the auxiliary machinery installment like hand fingernail which adapts, it only then can become the practical production equipment. Air operated not only is 1.th robot main drive type is quick-moving requesting machinist terminal execution quick-moving, the structure simple, the control maintenance convenient, the cost to be low, Moreover the flexible transformation quick. and has the versatile assembly and the transporting and so on "ascends when puts", the transmission movement work, uses air operated, or air operated combines with other transmission control technologies further increases its movement precision and the flexibility relatively fixed. Moreover the movement is frequent, the duplicated strong center low power operating mode in the work space scope limited, working routine, and uses the air operated modular organization unit the combination to realize the machinist work, can manifest the air operated technical effective substitution manpower operation realization production process Taiwan physics and chemistry and the automated characteristic and the superiority. It can be fast to the air operated machinist's basic request, accurately ascend to put requests them with transporting thing. To have the high accuracy, the rapid reaction, the certain bearing capacity, the enough working space and the nimble degree of freedom and in the free position all can characteristic and so on automatic positioning. Designs the air operated machinist's principle is: Full analysis work object (work piece) the work specification, and draws up the most reasonable work working procedure and the craft. And satisfies the system function request and the environmental condition; explicit: The work piece structure shape and the materials behavior, the pointing accuracy request. capture, time the transporting stress characteristic, the size and the quality parameter and so on, thus further determines to the machinist structure and the operating control request; The as far as possible designation standard module, the simplification design manufacture process. Pay attention to both versatility and special-purpose, and can realize the flexible transformation and the programming control.The air operated hand fingernail is the present machinist transports, the assembly class machinist in particular in captures in the technology to apply most universal way. it to be possible to realize bidirectional captures, voluntarily to the center, moreover the redundant precision high. Capture the strength to be constant. and may conveniently match meets each kind of jig. The air operated hand fingernail is direct connection between the machinist and of the work object, the careful analysis, chooses the good air operated hand fingernail to relate directly to machinist's operating performance. In the actual movement, the hand fingernail supports on both sides the strength to be supposed to guarantee is bigger than all static and the dynamic strength sum total. The PLC procedure movement way is circulates the scanning way, but the non- order carries out the way, therefore any manipulator satisfies after its condition namely starts the movement. Between various is parallel. The machinist is the multi-degrees 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 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; The pneumatic system electromagnetism cross valve selects the afflux board collection attire method, reduced has taken the space. 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 compression 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 components transportation and automatic assembly, food packing and the transportation, the electronic products transportation, automatic peg grafting, process and so on ammunition in production automation is widely applied. Therefore. The pneumatic actuator is one kind easy to promote popularly realizes the industrial automation application technology. The pneumatic system application caused the various countries industrial field to take generally. Most uses the programmable controller at present as the pneumatic system control device (PLC). The programmable foreword controller is take the microprocessor as a foundation, comprehensive computer technology, the automatic control technology and the communication 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 foundation, the microswitch and so on is composed. Clamps 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 complete the work piece separately the capture and the adsorption, adapts the different type material transporting. Clamps the hand to use the electro-magnet to attract gathers with separates the way clamp material. Clamps the hand or the sucker in rises and falls the air cylinder under the function to be possible to reciprocate; Clamps the hand or the vacuum cup together with rises and falls the air cylinder to move the air cylinder in about under the function to be possible to control along the column 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 circulation.This system can realize a material in plane transporting. Operates the kneading board to install in the electrically controlled box, is separates with the test installation main body. The 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 working. After moreover, the material is clamped the hand transporting completes, for satisfies continuously acts the need, but also must ship this material the zero point position, will supply the next time to transport the need.The system may complete each working is as follows.On 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 material.Material transporting system 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 back. In 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 material. May realize the single acting under the PLC control, act continuously the working. On 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 procedure. Single acting working: To clamps hand each movement using the button alone to carry on the control. Continuously: 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 complete last cyclical the work, returns to the zero point, auto-stop.Can realize the material autocycle transporting based on the PLC control material transporting system.This 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 electromagnetism 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, completes the material the transporting. Regarding small and medium-sized enterprise, as a result of fund and technical limit, not impossible disposable equipment integrity control system, like DCS system.But PLC is the general controller. Standard building block system hardware architecture, modular software design. May 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 compatible machine, the necessary commercialization 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 investment. Therefore, as the foundation process control system may constitute one kind take PLC the complete product which is advantageous for the user to organize voluntarily.
