The 1 SN series that summarizes my factory to use records model machine is the 1985 complete set device that introduce from Japan, because equipment uses time to grow, electric control system malfunctions constantly, major line board basic ageing. Digital switch is used in great quantities on electric controller, because be used for a long time, bring about a contact undesirable, make the control system response of equipment not sensitive, control precision is poor, wave motion of pressure of the machine that note model is big, the product quality that production gives is not stable, manufacturing efficiency is low. Accordingly, the decision notes model machine to undertake technical reformation to SN series, the FA that we chose control system to grow Inc. of new science and technology to produce shoot a plane programme controll implement. The application of 2PLC controller reachs the principle flying development as electronic technology, the PLC application on the machine that note model is increasingly general already in recent years, make the control level of the machine that note model raised a new level, PLC can realize the control of real time sex to recording model machine, namely alleged control is to show the calculation that uses PLC and control will doing craft what satisfy the machine that note model normally, at this moment the injunction that PLC replaced the Electromechanical that note model to enrage the composition such as the commonly used relay in controlling a system, transistor forms loop, appoint control loop to wait. Rose to control precision, reduced noise, simplified electrical system and maintenance workload. PLC controller has reliability tall, interference rejection capability is strong, one kind is controlled for industry only and design, adopted the measure of a lot of interference rejection on software and hardware, be diagnosed like wave of screen, filter, sound insulation, breakdown and restore automatically to wait. These measure increased the capacity of the dependability of PLC and interference rejection greatly. Want to undertake man-machine interaction above all before the mechanic that note model is made, the craft that jockey person asks place enters several data, be like: Of the machine that note model leave, combine modular speed and pressure, the speed of inject and pressure, goods carries the rotate speed of the rate that give and pressure, screw on the head, the control time of each behavioral phase, in the data input PU such as switch position of the movement, when the machine that note model enters working state, each craft parameter (control is variable) it is the detecting element that carries all sorts of kinds (sensor) undertake detecting with monitoring, sensor (pressure, displacement, speed, temperature) all sorts of signal that detect place, change through inputting interface circuit and modulus (device of A ／ D) , in entering PLC undertake comparative mixing with the fiducial data that stores beforehand operation, deviate signal, repass data is changed (device of D ／ A) and electric current of output of output interface circuit, voltage goes controlling element, have pressure to noting each actuator that look, speed, the control of the respect such as displacement, time, temperature. 3FA shoot a plane programme controll implement programme controll appliance of introductory FA has: (1) temperature controls a share: Temperature of canister of 7 paragraphs of makings controls a system (take fluctuation to be restricted temperature lock decides functional) , system of 1 paragraph of oily lukewarm control, each temperature paragraph program of independent PID figure, the 1st paragraph of temperature but set small constant temperature is controlled (use SCR) . (2) registers model flow share: 4 paragraphs of positions note model parameter to control, 4 paragraphs of time are protected press parameter to control, time notes model and positional switch to maintain the function that control an aspect. Shoot be not worth and shoot makings spill over examination function. (3) store makings shedding part: 2 class pine is retreated, function of 3 course feed in raw material, two kinds shake a program, automatic makings canister cleans a function. (Part of 4) mould flow; 4 paragraphs open modulus to occupy processing, modulus of 4 paragraphs of locks occupies processing, lock up modular function quickly, full automatic the function that move a model. (The share is treated in the center of 5) ; Program of PLC high-ranking ladder edits, mutiple level password space runs a system, 30 act operate data processing or monitoring page. 60 moulds parameter stores memorial function, mode of 3 kinds of different operations. Function of clew of 50 multinomial breakdown, dynamoelectric and lubricant system is handled in the center of, a variety of manufacturing computation functions, the input outputs bit of diagnostic function, real time bell displays a function. (6) movement coordinates a part: Multistage and independent turn set of class delay weighing apparatus. Set of weighing apparatus of delay of urgent or special action, scale outputs a curve to correct a function, linear input outputs correction function. (7) asks modular flow part: Shake the function that ask a model, hold function of modular defer discrepancy in the palm, 2 groups play function of gas drawing of patterns, neutron of 2 groups of all-round (clumsy core or come back) function, manipulator connection program. 4 circuit are transformed reach move above all we will divide the output end outside dominating electromagnetism a powerful person or family directly to keep apart relay with two board bridge is received, in order to increase the interference rejection capacity of controller: It is to expect the canister is added respectively lukewarm keep apart with board (A board) , motor is started, electric heat is started, warning apparatus, manipulator is started with a segregation board (B) , input, output 10 interface board FA-4, wiring of FA-6 reference point. Analogy, tally of digital, high speed FA. 1 board, temperature controls interpose aspect if FA-2 board pursues 4. With full automatic working flow is exemple: By the operation the motor on face plate starts key, 12 output end outputs FA-6 board motor actuating signal, through keeping apart ／ relay board B(3) puts through. Voltage of 220 bend over often shuts contact SB1, SB2, SB3, hot relay through urgent switch the control electromotor such as RJ is started, KM2, KM2, .
2, call the police for electromotor overload protective end. What go up by operation face plate is full automatic key, current exit or hind when exit is opened, x02A, X02B often shuts contact to disconnect, FA one 410 board 8, 9 inputs end is tall n, FA-610 board 10 output alarm signal. Before should be being shut, hind when exit, x02A, X02B puts through, FA-410 board 8, 9 inputs end is low n, program controller issues the statement that shut a model, union closes cost of modular parameter set, finish shut a model fast, shut a model slow fast, the movement such as model of lock of low-pressure protection, high pressure, after shutting a model to reach the designated position, x00 closes, inject an advancement, after reaching the designated position, x01 closes, begin to have inject flow (include inject among them, protect pressure, beforehand the behavioral) that the parameter set place such as model asks, modular technological process is entered after finishing. Set of parameter flying a model includes a model slow fast, fly a model fast, decelerate flying a model, open a model to stop. After opening a model to reach the designated position, FA-610 board 7 output end outputs manipulator actuating signal, go keeping apart ／ relay board B(I) , the manipulator that start. CNC Milling
