Shared GP1 sets stretching, speed, the elongation sum counter of each unit, and setting value is delivered to each servo motor by CPU MP920, and servo motor can be driven by the setting value among Fig. 2.At each operating unit, the physical quantity that is activated can detect by sensor.CPU MP920 is returned in detected data transmission, stores and adjust the data that set and the data of detection at CPU.On the other hand, under the situation of tape sizing, the GP2 of the transfer gantry unit 5 that separates receives the data of relevant yarn speed and stretching, and these data depend on the setting of shared GP1; Drive servo motor or according to circumstances adjust servo motor.Sensor to the physical quantity transmission return CPU MP940, store and adjust the data and the detected data of setting.
In Fig. 2 and Fig. 4, there is a mark not describe, the elongation control section of " a " representative between supply roll unit 4 and starching roller unit 3, in Fig. 2 and Fig. 4, also have a mark not describe, the elongation control section of " b " representative between cylinder unit 2 and starching roller unit 3.
To at length introduce embodiments of the invention below.
As shown in Figure 2, on the GP1 screen, set speed, stretching, the elongation sum counter of each operating unit according to thread material.The data of setting on GP1 are delivered to CPU MP920.The data that CPU MP920 receives are delivered to each servo motor (the AMP1 servo motor is to the AMP4 servo motor), and each servo motor is operated according to the data of input.
The servo motor of doff unit 1 (AMP1 servo motor) is received the laggard line operate of data that is transmitted by CPU MP920.Being connected to load on the load cell of tensile roller (twined raw yarn through axle) detects by stretching amp.The data that detect are returned CPU MP920 by the servo motor transmission.CPU MP920 compares data of receiving and the data that are delivered to servo motor, to regulate data.The data of regulating are delivered to servo motor again, and the driving operation of servo motor is controlled, and the speed of yarn and stretching are maintained fixed.
When CPU MP920 data that set and that transmit are passed to the servo motor (AMP2 servo motor) of cylinder unit 2,2 simultaneously operatings of cylinder unit.Cylinder unit 2 detected data are transmitted back CPU MP920 again and are carried out data comparison and adjustment, and the servo motor (AMP2 servo motor) of cylinder unit 2 can be operated with controlled.
The setting data of the setting data of the setting data of the servo motor of 4 pairs of doff unit 1, supply roll unit, the servo motor of cylinder unit 2 and the servo motor of starching roller unit 3 compares and adjusts, then the data of adjusting are delivered to servo motor (AMP4 servo motor), servo motor can be operated and control.
In Fig. 1, GP1 sets stretching, speed, elongation and the twining amount of each doff unit 1, cylinder unit 2, starching roller unit 3, supply roll unit 4.The data that CPU MP920 combination and control GP1 set are then according to each servo motor of data-driven, to carry and finished yarn.When the yarn that processes be wrapped on the transfer gantry unit 5 through axle the time, GP2 receive have yarn stretch, through the standard of axle and the data of operating condition, wherein operating condition has carried out adjusting to meet the condition of work of transfer gantry unit 5 at the whole set of data of GP1 and CPU MP920.GP2 transfers data to CPU MP940, carries out suitable correction and setting at cpu data.Then, data are delivered to the servo motor (AMP5 servo motor) of transfer gantry unit.Servo motor is operated according to these data, and CPU MP940 is returned in the content of operation transmission.Next, transfer gantry unit 5 receives again and carried out the data that correct through the size of axle and draw ratio after, and operates according to these data, thereby keeps even velocity and stretching.
The present invention has carried out the reaction speed of different motors under the true service condition of motor and the comparative experiments of efficient.Following table has shown the reaction speed and the efficient of different motors.Should be understood that and from table, can see according to having huge difference between the d.c. motor of servo motor of the present invention and prior art or the AC vector prosperity.
