Man-machine interface 7 adopts Siemens MP270 man-machine interface 7, is provided with more than 30 operation pages in the program, and complete function is easy to operate.
The inventive method has realized following function control by the exploitation to SCOUT software:
1), the high-speed carry and the function of giving up the throne fast.The version roller diameter of satellite-type flexible steel roller printing machine can change along with the difference of printing, when printing plate cylinder is installed, in the time of version roller erection support need being withdrawed from, import exit instructions and withdraw from the position in man-machine interface 7, master controller 1 sends command signal to Dual-motors Driving module 4, Dual-motors Driving module 4 control servomotors withdraw from a high speed, the current place value that the absolute value encoder of the motion controller of servomotor after by motor read motor, when the limit sensors A of position is withdrawed from the arrival setting, limit sensors A gives 1 one signals that put in place of master controller, master controller 1 sends the instruction stop signal to Dual-motors Driving module 4 again, Dual-motors Driving module 4 control servomotors stop, version roller erection support keeps the motionless edition roller that carries out of current location to install, after installation, advance edition roller instruction and enter an edition position in man-machine interface 7 inputs, master controller 1 sends command signal to Dual-motors Driving module 4, Dual-motors Driving module 4 control servomotors advance an edition roller at a high speed, arrive the limit sensors B of combined pressure position fast, limit sensors B gives 1 one signals that put in place of master controller, master controller 1 sends command signal to Dual-motors Driving module 4 again, and Dual-motors Driving module 4 control servomotors stop.So, just shorten the time that the version roller is installed, improved operating efficiency.
2), anti-extrusion version roller function.Satellite-type flexible steel roller printing machine if operation is wholwe-hearted inadequately, will make the feeding excess in the process of version roller and anilox roll feeding pressure regulation, squeeze bad version roller or anilox roll, causes damage.In program, position restriction and moment limitation function have been increased.According to the size of version roller, set the scope that seesaws of version roller bearing, if operation exceeds limited field, master controller 1 control is sent command signal to Dual-motors Driving module 4, Dual-motors Driving module 4 servomotors stop automatically, prevent to squeeze the version roller; Again it; if it is improper that the position restriction is provided with; cause edition roller or anilox roll to bump against miscellaneous part; the output torque of servomotor can suddenly increase; the output current of driver element can suddenly increase, and master controller 1 detects and obtains this signal that skyrockets, and can send command signal to Dual-motors Driving module 4; Dual-motors Driving module 4 is controlled servomotor at once and is shut down, and prevents to squeeze the version roller.
3), according to the automatic positioning function of version roller girth.When the diameter generation conversion of version roller, need not manually to make edition roller to be fed into suitable position, only need new version roller parameter by man-machine interface 7 inputs, master controller 1 will calculate publishes the corresponding position location of roller, the control servomotor is automatically fed into this position, again as required, manually adjust slightly and get final product.
4), according to the automatic Regulation function of different printing speed.Satellite-type flexible steel roller printing machine will guarantee the uniform quality of printing under the different situation of track speed, just must be when different linear velocity, and the force of impression of version roller and anilox roll is different.Carry out tachometric survey by motor encoder, master controller 1 can be according to current linear velocity by comparing and handling, send command signal to Dual-motors Driving module 4, Dual-motors Driving module 4 is adjusted the motion of servomotor automatically, in time adjust the force of impression between version roller and the anilox roll, guarantee the uniformity of print quality.
5), automatic formulation function.When the version roller girth of version roller not simultaneously, the suitable pressure position of different version rollers is different.For same registering roller, if repeatedly print at interval, will carry out the pressure adjustment repeatedly by hand in the operation, reduced operating efficiency, therefore by statistics, the pressure adjustment of different version rollers is made into the form of prescription, " respective value prescription " as a kind of edition roller girth and pressure position, pressure regulation location parameter to each registering roller is numbered storage, when using different version roller, as long as at the corresponding prescription of man-machine interface 7 inputs number, master controller 1 sends command signal according to the numbering of storage to Dual-motors Driving module 4, the motion of Dual-motors Driving module 4 control servomotors is automatically fed into corresponding pressure position.
6), outage memory function.Under the situation of or non-artificial unexpected outage artificial at control device, master controller 1 can be remembered the clutch pressure and the pressure position of current version roller, after re-powering, as long as in man-machine interface 7 input memory control instructions, master controller 1 can carry out the parameter setting according to memory area before, and printing just can be directly implemented in the motion of control servomotor, reduce the time of readjusting, improved operating efficiency.
The inventive method is at the technological requirement and the operation requirement of satellite-type flexible steel roller printing machine pressure regulation, use movement control technology and servo control technique, build by rational hardware, realized the multinomial function of satellite-type version roller pressure regulation, operating efficiency and pressure regulation precision in the operation of version roller have been improved greatly, reduce workman's manipulation strength, guaranteed printing quality.
