Abstract

PROBLEM TO BE SOLVED: Not to cause a state of too loose or too tight winding of wound-up cloth by carrying out automatic torque control by controlling a torque motor provided on a cloth winding mechanism by a motor automatic control device. SOLUTION: At the time when a motor automatic control device of a cloth winding mechanism works, an electric power source circuit 1 receives an electric power source provided outside and supplies the electric power source required by the circuit. An analog signal processor 2 sends a signal to a power amplification output circuit 3, the power amplification output circuit 3 sends the signal to an outside torque motor after amplifying it, and it rotates the outside torque motor. When the outside torque motor is rotated by driving a winding shaft, an operator carries out change-over operation of a shift position of a second change-over switch 82 in a torque adjustment circuit 8. Consequently, a state of too tight or too loose winding of cloth wound up by the cloth winding mechanism is not caused, and quality of woven cloth is improved by uniforming weft of a cloth head and a cloth tail.

The tightness of the cloth to be wound is adjusted by turning the adjustment bolt 135, and the adjustment bolt 135 presses or releases the torsion spring 13 to thereby adjust the belt 136.
Was made to be nervous or loose. However, in the method of manually adjusting the winding tightness of the roll of the winding shaft, if the belt 136 is adjusted too loosely, the winding shaft may not be able to take up the cloth or may slip in the roll. However, if the adjustment is too tight, the winding of the roll becomes too tight, the texture of the cloth is deformed, the texture of the cloth is destroyed, and it becomes difficult to pull out the winding shaft from the roll. At the time of winding, as the roll becomes larger and heavier, the cloth cannot be made uniform and the quality of the woven cloth cannot be matched unless the tensile force of the cloth is gradually increased. However, although the well-known lower winding mechanism has an adjusting device using a torsion spring, it does not have a function of gradually increasing the torque, and therefore the cloth head and the cloth tail do not match, Influenced the quality of the woven fabric.

3 and 4 are an electric circuit block diagram and an electric circuit diagram of an automatic motor control device for a cloth winding mechanism according to the present invention. The automatic motor control device of the cloth winding mechanism according to the present invention includes a power supply circuit 1 inside the automatic control circuit, an analog signal processor 2,
Power amplification output circuit 3, abnormal signal detection circuit 4, abnormal signal output circuit 5, abnormal external signal circuit 6, speed adjustment circuit 7, torque adjustment circuit 8, external torque motor 9, external detection speed receiver 10, and torque It comprises an automatic increase circuit 11. Note that there are two sets of the same electric circuit in the electric circuit, and one set of the electric circuits will be described here.

When the automatic motor control device of the cloth winding mechanism operates, the power supply circuit 1 receives an externally supplied power supply and supplies the power required by each circuit. The signal is sent to the power amplification output circuit 3, which amplifies the signal and sends it to the external torque motor 9 to rotate the external torque motor 9.

When the external torque motor 9 drives and rotates the winding shaft (not shown in the figure), the winding of the roll of the winding shaft may be too tight or too sweet to prevent the winding shaft from being pulled out. Or, in order to prevent swinging, the operator performs the switching operation of the shift position of the second switch 82 in the torque adjustment circuit 8. The second changeover switch 82 is switched to the first shift position 823 and the third variable resistor 824 is set.

This section is set by an experienced operator by a cloth roll to 50 to 2000 revolutions by the third variable resistor 824 in the torque adjusting circuit 8, and the external torque motor 9 drives the winding shaft. The automatic control of the torque increase during 50 to 2000 rotations is performed by the externally detected rotation speed receiver 10 detecting and counting the rotation speed of the external torque motor 9 (the higher the rotation speed, the heavier the roll on the winding shaft). Then, when the external torque motor 9 needs to increase the torque, the externally detected rotation speed receiver 10 sends one signal to the automatic torque increasing circuit 11, and the automatic torque increasing circuit 11 further adjusts the torque. After controlling the circuit 8,
After passing through the analog signal processor 2 and the power amplification output circuit 3,

The external torque motor 9 drives the winding shaft to perform winding. When the winding is completed, the winding shaft stops for the first time and enters the WR as shown in FIG. The external torque motor 9 is controlled by software in the analog signal processor 2 and dust is removed by a blow gun within the setting of the WR value.
At the time of dust removal, cotton lint and dust of the cloth solidify and rotate to the lower part of the cloth, where the cloth is cut with scissors (second reel stop). When the first roll winding of the cloth is completed, the external counter (not shown in the figure) receives the rotation value newly set by the operator again and performs the next winding.

When the external torque motor 9 becomes uncontrollable, stops rotating, or breaks down,
The abnormal signal detection circuit 4 sends one signal to the analog signal processor 2 and, after passing through the power amplification output circuit 3, causes the external torque motor 9 to stop the winding operation. At the same time, the abnormal signal detection circuit 4 sends this signal to the abnormal signal output circuit 5,
Stop the loom operation on the loom.

When the external loom stops the weaving operation due to a certain situation, this status signal is received by the abnormal external signal circuit 6 and then sent to the analog signal processor 2 to control the external torque motor 9. The operation is stopped.

Further, when the rotation speed of the external torque motor 9 itself is too high or too low, the rotation speed of the external torque motor 9 can be corrected by the speed adjustment circuit 7. However, the rotation speed setting of the external torque motor 9 is set in the speed adjustment circuit 7 when the electric circuit board leaves the factory.

Further, when the pulling force of the upper roller during the operation is insufficient, the third changeover switch 83 in the torque adjusting circuit 8 is depressed, and the fifth variable resistor 831 is further adjusted. A single pulling force is provided to the upper roller to pull it, making it easier to control by the third variable resistor 824.
