For the guide roller of yarn guide, including main traverse line wheel 8 with from guide roller 3, it is respectively fixedly connected with in being arranged on Main traverse line on described fuselage 1 takes turns servomotor 9 and from guide roller servomotor 4, and its rotating speed is according to electricity Sub-gear is than setting;
For winding yarn reel 5, it is connected with winding servomotor 6 by toothed belt transmission;
Winding servomotor 6, connects band movable reel 5 by Timing Belt and rotates;
Tension pick-up 7, for measure in real time the Tensity size of yarn between main traverse line wheel 3 and reel 5 and its Variable quantity, is delivered to controller by above-mentioned amount;
Controller, for receiving the rotating speed of winding servomotor 6, connecting the guide roller servo of main traverse line wheel 8 Tensity size and its variable quantity that motor 4 rotating speed and tension pick-up 7 gather control to wind servomotor 6 in real time And connect guide roller servomotor 4 rotating speed of main traverse line wheel 8.
Described main traverse line wheel servomotor 9, from guide roller servomotor 4 and winding servomotor 6 and servo Driver connects, and described servo-driver is connected by Ethernet with controller.Described main traverse line wheel servo electricity Machine 9 and be two ASD-A2-0421-E servomotors from guide roller servomotor 4, they are respectively with corresponding Servo-driver be connected, one is set to main shaft, and another is set to from axle.The rotating speed of main shaft is by controlling Device determines according to the technological parameter of input, is a fixing gear from the rotation speed relation of the rotating speed of axle Yu main shaft Ratio relation, this gear determines than by the size of two guide rollers.Main shaft and after axle length velocity relation determines, When machine startup and stopping, main shaft and the operating between axle keep basically identical, make yarn in principal and subordinate's axle institute Smooth running between the guide roller connected.
The present embodiment uses and uses AC servo motor to substitute the frequency conversion motor driving electricity as master and slave guide roller Machine, AC servo motor connects servo-driver, by ethercat bus and controller between servo-driver Connect;
Embodiment two
A kind of automatic inlet wire method based on described automatic wire inlet system, including step:
(1) set the stabilized (steady-state) speed of main traverse line wheel 8, put machine startup button;
(2) main traverse line wheel servomotor 9 is according to the parameter of electric machine set, and is accelerated motion;
(3) setting gear with main traverse line wheel 8 by controller from guide roller 3 to engage, gear ratio is set as 1:1;
(4) obtain tension value in real time, calculate the output k of tension force Control PID according to tension valuePIDoutValue, kPIDout Value be limited between-1 to 1, kPIDoutCan be such relation with the relation of tension force: when tension force is more than setting During definite value, kPIDoutIt is negative;When tension force is less than setting value, kPIDoutFor just;
(5) according to formula k=kPIDoutΔ+1 and vReel=k vMain directive wheelCalculate the linear velocity of reel in real time, adjust according to it The rotating speed of joint reel motor 6, v in formulaMain directive wheelMain traverse line wheel 8 operating is driven for guide roller spindle servo electric machine 9 Linear velocity, vReelFor the linear velocity of reel servo motor 6 band movable reel 5 operating, k is proportionality coefficient, its Span is between 1-Δ and 1+ Δ;
(6) after main traverse line wheel 8 current rotating speeds reach the 95% of setting speed, wire inlet system enters steady statue;
(7) machine stable operation, repeats step (4)~the operation of step (5);
(8) some machine stop button;
(9) main traverse line wheel servomotor 9 is according to the parameter of electric machine set, and carries out retarded motion;
(10) step (4)~the operation of step (5) are repeated;
(11) take turns main traverse line wheel servomotor 9 after current rotating speed reaches below 200r/min when main traverse line and stop fortune Dynamic, the also stop motion of other servomotors, whole control process terminates.
Specifically, in step 4, the described output k calculating tension force Control PID according to tension valuePIDout's Value step particularly as follows:
Step 41, calculate the tension value that records of current tensile sensor with deviation value Deviation setting tension force, To this deviation value of current sample period and Isum, current tensile deviation value and the tension variation in previous moment Difference Rate of value, the value of the described Deviation of the present embodiment is 8g, and the value of described AI_Max is 30g;
Step 42, calculating kPIDoutValue:
