Please refer to Figure 3, as shown in the figure, the automatic control motor device of the cloth rolling mechanism of the present invention is composed of a power supply 1, an analog signal processor 2, a power amplification output unit 3, an abnormal signal detection unit 4, and an abnormal signal output unit 5 , an abnormal external signal unit 6, a speed adjustment unit 7, a torque adjustment unit 8, an external torque motor 9, an external detection revolution receiver 10, and an external automatic torque increase unit 11 (there are two sets of identical constituent units in the device) , only a group of constituent units will be described here).

When the automatic control device of the cloth rolling mechanism is working, the power supply 1 accepts the power supply provided by the outside to supply the power required by each constituent unit. At this time, the analog signal processor 2 inputs this signal into the power amplification output unit 3 of the next stage. The signal is amplified by the power output amplifying unit 3 and sent to the external torque motor 9 to make the external torque motor 9 rotate.

Please refer to Figure 4 and Figure 4-1, they constitute the electrical schematic diagram of the block diagram shown in Figure 3 above, wherein the torque adjustment unit 8 includes 6 external terminals CN-3P1, CN-3P2, CN-3P3, CN-3P5, CN -3P6, CN-3P8, wherein, the terminal CN-3P1 connects the fifth variable resistor 831 through the push switch 83 and the knife of the first switch 81 through the push switch 83' respectively; A throw 811 connects the second variable resistor 812 through the normally closed throw of a switching terminal K112 of the relay K11 and connects the first variable resistor 814 with the other throw 813 of the first switch 81; the terminal CN- 3P2 is connected to the other end of the first, second and fifth variable resistors 814, 812, 831; the terminal CN-3P3 is connected to the knife of another switch terminal K113 of the relay K11 through the knife of the second switch 82, and its one throw 821 The normally closed throw of the switching terminal K113 is connected to the fourth variable resistor 822, and the normally open throw is connected to the third variable resistor 824 and another throw 823 of the second switch 82; the terminal CN-3P5 and the terminal CN-3P6 They are respectively connected to the energized coil K111 of the relay K11; the terminal CN-3P8 is connected to the other end of the third and fourth variable resistors 824 and 822.

When the external torque motor 9 drives the cloth rolling stick (not shown in the figure) to roll the cloth, in order to prevent the lower rolling stick 122 from rolling the cloth too tightly or too loosely, causing the cloth rolling stick 122 to be unable to be pulled out or loosened, so the problem for the operator When the second switch 82 in the torque adjustment unit 8 is set to the first gear 823, the third variable resistor 824 can be adjusted, and the adjusted data is in the range of 0 to 50 as shown in Figure 6 (unit W is also weight Calculated by the number of revolutions, "0" is also the starting point of the tension increase, R is also the size of the tension output, WR is the number of revolutions required for dust removal) the curve is the initial cloth winding setting, and the setting of this data It must be set according to the experience of the operator, so as to prevent the cloth rolling stick 122 from being too tight or too loose when rolling the cloth, and when the second switching switch 82 is set to the first gear position 823, no matter whether the cloth is rolled down or not. Whether the pulling force of the stick 122 is in operation or when it is stopped, it is all adjusted by the third variable resistor 824. The pulling force also needs to adjust the third variable resistor 824 , and the pulling force of the down-rolling cloth stick 122 during shutdown requires adjusting the fourth variable resistor 822 .

Continuing from the above, before the cloth is rolled by the lower cloth roll 122, the cloth will first pass through the upper cloth roll 121 (not shown in the figure) of the cloth rolling mechanism. When 81 cuts the first gear position 813, to adjust the first variable resistor 814, and the pulling force of the rolling cloth stick 121 in operation or the pulling force during shutdown is all adjusted by the first variable resistor 814, If the first switching switch 81 is set to the second gear 811, the pulling force during operation is to adjust the first variable resistor 814, and the pulling force during shutdown is to adjust the second variable resistor 812.

Continuing the above, please refer to the 50-2000 curve in Figure 6. The setting here is for an experienced operator to set the third variable resistance group 824 in the torque adjustment unit 8 from 50 to 50 according to the cloth. 2000 revolutions, and the control of automatically increasing the torque of the cloth rolling stick 122 between 50 and 2000 revolutions driven by the external torque motor 9 is also the number of revolutions of the external torque motor 9 detected and counted by the external detection revolution receiver 10 (due to the rotational speed When more, the weight of the cloth rolled by the lower cloth stick 122 is heavier), after the external torque motor 9 needs to increase the torque, the external detection revolution receiver 10 will send a signal to the external automatic torque increase unit 11, and then the external torque unit 11 will automatically increase the torque. After the automatic torque increase unit 11 controls the torque adjustment unit 8, the external torque motor 9 increases the torque through the analog signal processor 2 and the power amplification output unit 3, so that the external torque motor 9 can drive the cloth rolling rod 122 to roll the cloth outside. After the torque motor 9 drives the cloth rolling roller 122 to finish rolling the cloth (the first shutdown), it enters the setting of WR as shown in Figure 6, which is the number of revolutions required for dust removal, and its value is set by analog signal processing The program in the device 2 is used to control the external torque motor 9. Within the setting of the WR value, it is to pick up the air blow gun to remove dust. When removing dust, the cloth will produce a layer of cotton black circle, and the black circle of cotton wool just rotates to make it rotate To the place where the cloth is lowered, that is, the place where the scissors are used to cut the cloth (the second stop), when the first cloth roll is completed, the external counter (not shown in the figure) accepts the revolution value reset by the operator again , to roll the next piece of cloth.

In addition, when the external torque motor 9 is out of control or does not turn or fails, the abnormal signal detection unit 4 outputs a signal to the analog signal processor 2, and after the power amplification output unit 3, the external torque motor 9 is stopped. The VR value is connected to the terminals CN-3P1 and CN-3P2 in the analog signal processor 2, which output the control current after being processed by the internal Q1 and Q2; at the same time, the abnormal signal detection unit 4 The signal is sent to the abnormal signal output unit 5 to inform the knitting machine to stop the weaving action.

Also, when the external knitting machine stops weaving due to some condition, the status signal is sent to the analog signal processor 2 after receiving the signal by the abnormal external signal unit 6 to stop the external torque motor 9 from winding the cloth.

Again, if the rotating speed of the external torque motor 9 itself is too fast or too slow, the speed adjustment unit 7 can be adjusted to correct the rotating speed of the external torque motor 9; but the rotating speed of the external torque motor 9 has been set when the circuit board leaves the factory The rotational speed of the external torque motor 9 is set in the speed adjustment unit 7 .

Again, if the rolling cloth stick 121 in operation has insufficient pulling force, the third switching switch 83 in the torque adjustment unit 8 can be pressed, and then the fifth variable resistor 831 can be adjusted to provide a pulling force in an instant. After the cloth stick 121 is rolled up, it is controlled by the third variable resistor 824 again.

Please refer to Fig. 5, as shown in the figure, the control process of the present utility model is to enter into the power supply 21 first when the automatic control device starts to act, and then enter to judge whether it is the power rectification 22, if it is not the power rectification 22, then Enter the display light is not on 28, and then enter the fault processor 29; if it is judged as power rectification 22, then enter the adjustment variable resistor to determine the pulling force 23, and then enter the analog processing 24 and power amplification signal 25, and then enter Control motor 26, then enter motor stall or idling 27, just enter display light not bright 28, enter fault processor 29 again.

Please refer to Fig. 7, as shown in the figure, an upper cloth rolling stick 121 is provided on both sides of the cloth rolling mechanism 12 to pull the cloth woven by the knitting machine to the lower rolling cloth stick 122 for rolling cloth. An external torque motor 9 is respectively housed in both sides in 12, and the above-mentioned automatic control device is used to control the cloth rolling stick 121 and the external torque motor 9 to drive the cloth pulled down by the rolling cloth stick 121.
