Scroll retraction detection sensor is separately mounted to the extreme position that Scroll extends and retracts, and feeding cylinder feeding passes in place
Sensor is mounted on the extreme position that feeding cylinder stretches out.
Second of technical solution that the present invention uses is that a kind of electric control method of servo winder is watched using one kind
The electric control system of winder is taken,
When not actuated, human-computer interaction interface setting locating speed is first passed through, rolling speed, winding geard-down speed, metering subtract
Fast length, metering length；
After startup, traction pressure roller pushes, and winding servomotor is rotated with the locating speed set, is passed when Scroll positions
Sensor detects signal, and winding servomotor stops rotating, at this point, programmable controller stores current position location, completes
It positions for the first time；After completing to position for the first time, in the case where Scroll retraction detection sensor has signal, feeding cylinder is drawn
Feeding detects that signal or wallpaper are inserted into detection sensor and detect signal when feeding cylinder is fed to level detection sensor
When, pressure roller tripping is drawn, traction feeding cylinder is retracted, meanwhile, when wallpaper, which is inserted into detection sensor, detects signal, winding is watched
It takes motor and rewinding is started with the rolling speed set, when winding the length of length arrival metering slowing-down length setting, winding
Servomotor is decelerated to the winding geard-down speed of setting, and when reaching the metering length of setting, winding servomotor stops
Pressure roller combined pressure is drawn in rotation, and cut-off knife carries out cutting action, meanwhile, if Scroll retraction detection sensor has signal, it can compile
Metering storage area data is reset inside range controller, and Scroll returns, and Scroll can be according to current programmable while returning
Controller internal storage region by value, calculate and complete secondary location action, after the completion of location action, start feeding, no
It is disconnected to repeat the above action, realize automatic continuous winding action.
The locating speed that sets, rolling speed, winding geard-down speed as：
Set winding servomotor current rotating speed as V, unit r/min, programmable controller transmission target pulse
Frequency is S, and it is P that winding servomotor, which rotates one week required umber of pulse, then V=S/P；
Locating speed is set as the 2/3 of servo motor rated speed；Rolling speed is the 90% of rated speed, and winding is slowed down
Speed is the 2/3 of rated speed；Metering slowing-down length is the 90% of metering length.
Calculating to metering length is：It is calculated according to the perimeter of the encoder pulse number of rice counting wheel and rice counting wheel, when
Preceding metering length=rice counting wheel encoder count ÷ rice counting wheels encoder pulse number × rice counting wheel perimeter × fine tuning coefficient.
One week required umber of pulse P is rotated to winding servomotor to be calculated as：
It is C that note winding servomotor, which rotates one week encoder output umber of pulse, and winding servomotor rotates one week can
It is Q that programmable controller, which needs the umber of pulse sent out, and it is M to wind the reduction ratio between servomotor and Scroll, then：
Q*G=C*N,
Wherein, C is the resolution ratio of servo motor, and N is the number of turns of motor rotation, N=；Then there is Q=C/G；To obtain：
P=Q*M=C*M/G.

Panasonic's FX-P series of PLC, step instruction, pulse command control, the winding time is only 2S-3S；Servo motor, anti-interference ability
By force, reliability is high, fast response time, and control accuracy is high.
Tradition positioning carries out position feedback using two alignment sensors, due to being influenced by the sensor response time, often
There may be errors for secondary positioning, once position error is big, will have feeding can not accurately be sent into the jack of Scroll, cause
Paperboard also increases security risk during excluding paperboard to waste the winding efficiency of worker.Using of the invention high
Fast rolling machine electric control system needs two sensors often to determine a position and needs to acquire primary transducer position by original positioning
Data are reduced to and only use a sensor, and powered on for the first time, acquire primary transducer position data, carry out zero-bit memory work(
Can, problem is not allowed in positioning caused by greatly reducing each alignment sensor response speed lag in this way, and servo motor is again in addition
It is to be calculated current location by high-resolution encoder, substantially increases motor rotation precision.The addition of servo allows
The corresponding speed of motor also greatly improves, and it is about that 1ms is compared with variable-frequency motor and carried significantly to shut down feeding servo motor response speed
High response speed；
2) man-machine communication.High speed winding control system, the man-machine boundary person control and monitoring of use, picture color is gorgeous, essence
The appearance of cause and equipment perfect adaptation.
3) meters counting accuracy improves.Original rice counting wheel carries out real-time metering using rice counting wheel+metering controller to wrapup procedure
Judge, and is controlled using the rice counting wheel of 300 pulses.Since the umber of pulse of rice counting wheel is less, meters counting accuracy will be relatively
Difference.The rice counting wheel that the present invention is replaced with original rice counting wheel 300 pulses carries out control calculating, and directly send out rice counting wheel
Umber of pulse is sent into PLC high-speed counters channel, carries out the metering controller dress that PLC internal calculations eliminate original operation panel
It sets, it is ± 0.5cm that metering improves error till now by original error ± 3cm after improvement；
4) rolling speed is substantially improved.1 minute rolling speed of volume 10 can be achieved after system improvement, by winding ability by original
40-50 ms/min of the wallpaper printing speed come improves 80-90 ms/min till now, substantially increases the booting print of printing machine
Brush permissible velocity.
