The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is further described:
Shown in 1 figure, the present invention is by main motor 1, spindle encoder 2, computer system 4, frequency converter 5, servo controller 6, servomotor 7, warp let-off casing 8 and machine driven system 9 are formed, the output shaft of main motor 1 links to each other by the turning cylinder of belt with spindle encoder 2, drive spindle encoder 2 rotation outupt coded signals, after spindle encoder 2 will export computer system 4 (adopting ordinary PC to get final product) to the rotating speed code signal of main motor 1 to, control software computing through special establishment, give the woven every technological parameter that closes man-machine interface 3 (touch operation screen) input, as warp run-in, rotating speed, girth, density etc., computer system 4 calculates necessary running parameters automatically, and give frequency converter 5 with these transfer of data, the frequency circuit of the speed command Data Control master motor 1 that frequency converter 5 provides according to computer system 4 is to control main motor 1 rotating speed, and this moment, spindle encoder 2 detected the real-time rotating speed of main motor 1, and detection signal is sent to computer system 4.
The structure of spindle encoder 2 as shown in Figure 3, its model can be OVW2-06MHT, include encoder seat 23, encoder 24, yielding coupling 25, encoder coupling spindle 26, the motor pulley 29 of main motor 1 is connected with spindle pulley 28 on the main shaft 27 by belt.Main shaft 27 is used to connect other mechanical part.
Computer system 4 is according to the main motor 1 actual speed value of spindle encoder 2 feedbacks, combined process parameter (warp run-in, outer perimeter etc.), calculate various speed and location parameter, and send to servo controller 6 (model can be TSDA20C) with the pulse command form, servo controller 6 is after the service data of receiving computer system 4, amplify through internal arithmetic and signal, the rotation of control servomotor 7, the encoder that while servomotor 7 inside carry, service data is fed back to servo controller 6 in real time, this moment, servo controller 6 was in real time with service data (rotating speed, the position) feeds back to computer system 4, so that computer system 4 can be controlled in real time and adjust operating instruction rapidly, optimize service data, eliminate kinematic error as far as possible,, ensured the operation stability and the reliability of servomotor 7 to reach the optimum efficiency that operation with closed ring calculates.
As shown in Figure 2, servomotor 7 can be connected with warp let-off casing 8 (available decelerator 10 is realized) flange, the output wheel of decelerator 10 is by being with 11 to be connected with synchronous pulley 13 synchronously, the rotating shaft of synchronous pulley 13 with fixedly connected through axle 14, spindle nose seat 12 is installed at synchronous pulley 13 and between axle 14, plays fixation.Coiled hair 19 is being installed on axle 14, the warp thread 22 of reeling on the coiled hair 19, and by lever jack 21 and guide cap 15 derivation warp thread 22.Warp knitting machine warp thread in the braiding process is constantly woven, and during braiding certain warp tension must be arranged.Amount as the warp let-off is few, and the warp thread amount of braiding usefulness is many, and the tension force of that warp thread can be increasing, is exactly that 22 pairs of guide caps 15 of warp thread have a downward pressure, and the shift fork 20 on guide cap 15 and tension rail 18 and the tension rail 18 is rotated simultaneously.When warp thread 22 tension force are very big; pressure to guide cap 15 becomes big; make it drive tension rail 18 rotations; shift fork 20 upper ends on the tension rail 18 can touch the contact on the tension controller 17; when warp tension is too small; under the tension force effect of tension spring 16; the lower end of shift fork 20 can touch the contact of tension controller 17 equally; this moment, tension controller 17 will export the tension force detection signal to computer system 4; computer system 4 is defined as sending emergency-stop signal immediately after the stopping signal; make main shaft in a short period of time (about 0.5) out of service, thereby protection equipment and yarn do not break.While also shows the tension force fault-signal on the display screen of man-machine interface 3, operating personnel re-enter warp run-in or revise warp run-in, directly cause the warp run-in that reaches suitable, make the upper and lower side of shift fork 20 can not touch tension controller 17, machine just can normally weave running.
In the whole computer control system operation processing time very short (about 6ms), no matter trend stability that like this can the operation of assurance equipment be equipment stops from static startup or from high speed, and this electronic let-off control system all can be made optimum response real-time.And because native system adopts is multiple speed and position feedback, so computer system 4 can make the optimal dynamic adjustment in real time reliably, in the shortest time fault responded, with protection equipment and weaven goods.
