Abstract

The textile winding machine control circuit assembly, connected to the knitting machine, controls the operation of the textile winding machine in winding the knitted fabric. This includes a power circuit, an analog signal processor, a power amplifier controlled by the analog signal processor to rotate the textile winding motor, a speed control circuit to control the motor speed, a torque control circuit controlled by a rotational speed sensor, and an automatic torque boost control circuit to automatically increase the motor torque. There is also an external fault detection device configured to shut down the motor when the knitting machine stops, and another fault detection device configured to shut down the knitting machine when the motor malfunctions.

1. The textile winding machine control circuit assembly, connected to the knitting machine to control the operation of the textile winding machine in winding the knitted textile, consists of: a power circuit for correcting the external power supply to provide the necessary power to the assembly; an external fault detection device for monitoring the operation of the knitting machine; an external fault detection device that provides an abnormal signal when the knitting machine malfunctions; two external torque motors controlled to rotate the upper and lower textile winding rollers of the textile winding machine; an abnormal signal detection device for monitoring the operation of the external torque motors; an abnormal signal detection device that provides an abnormal signal to stop the knitting machine when the external torque motors malfunction; an output fault signal circuit connected to the knitting machine to receive the abnormal signal from the abnormal signal detection device to stop the knitting machine; an analog signal handler for receiving power from the power circuit to turn on the external torque motors and the abnormal signal from the external fault detection device, and an abnormal signal from the abnormal signal detection device to turn off the external torque motors; and a power amplifier connected between the analog signal handler and the assembly. The motor provides the aforementioned external torque, which is controlled by the aforementioned analog signal to regulate the motor's operation. A rotational speed detector detects the number of rotations of the external torque motor. A speed control circuit sets the rotational speed of the external torque motor, allowing the adjusted value to be processed by the analog signal handler and then sent by the power amplifier to control the motor's rotational speed. An automatic torque boost control circuit uses the rotational speed signal of the external torque motor, detected by the rotational speed detector, to control the torque of the external torque motor according to the received signal value. A torque control circuit is tuned to receive the torque control signal output from the automatic torque boost control circuit to increase the torque of the external torque motor. 2. The assembly of the textile winding machine control circuit of claim 1, in which such torque control circuit consists of a first switch that is moved between the first and second positions and a first variable resistor for controlling the torque of the upper textile winding when the textile winding machine is operating and when the first switch is moved to the first position. 3. The textile winding machine control circuit of claim 2, where such torque control circuit is further comprised of a second variable resistor for controlling the torque of the upper textile winding roller when the textile winding machine is stopped and the first switch is moved to the second position. 4. The textile winding machine control circuit of claim 2, where such torque control circuit is further comprised of a second switch which is moved between the first and second positions and a third variable resistor for controlling the torque of the lower textile winding roller of the said textile winding machine when the second switch is moved to the second position. 5. The textile winding machine of claim 4, where the variable resistor under the third such switch is controlled to limit the torque of the lower textile winding roller of such machine when the second such switch is moved to the second position during the operation of such machine. 6. The textile winding machine of claim 4, where the torque control circuit is further comprised of a fourth variable resistor for limiting the torque of the lower textile winding roller of such machine when the second switch is moved to the second position and when the textile winding machine is stopped. 7. The textile winding machine of claim 1, where the analog signal handling device is programmed with a set of instructions to control the speed of rotation of the motor providing the external torque during the dust removal process for moving cotton fibers from the textile being wound. 8. The textile winding machine of claim 6, where the torque control circuit is further comprised of a third switch and a fifth variable resistor. This fifth variable resistor is being controlled to provide the tension for pulling the upper winding roller of the said textile winding machine up. When the tension of the upper winding roller drops below a predetermined value, and the third switch is opened, the tension of the upper winding roller of the said textile winding machine can be further adjusted by the third variable resistor.
