(54) USGUSGVO TO MOVE THE EXTENSION FRAME

CARS

control motor 5. Pulse generator 6 generates a pulse for the constant rotation of one of a pair of rollers.

The control motor 5 is a pulse motor rotating in the forward and reverse directions at a predetermined angle in response to input signals, for example, the number of output pulses from the computing unit 7. The direction of rotation is determined by the selection.

The required movement of the extension frame in accordance with the program specified in block 8 is entered into the computing unit 7 and stored in it. The drive speed is then automatically adjusted according to this program.

The measured speed of the rollers 1 and 2 through the gearbox 4 and the pulse generator 6 is transmitted to the computing unit 7, and if there is a deviation from the allowable limits of the production program in block 8, it is corrected in block 7. In this device, the spin speed deviation is reduced to a minimum, the result is a stable and consistent product quality.

If the variable speed drive has several speed steps, for example three, and a switching clutch is used as the control motor 5, then it is possible. change the speed of the spinning pulse signal by controlling the computing unit.

The device (FIG. 2) comprises a drive 3, a pair of drive rollers 1 and 2 for feeding a portion of the fibrous material, a combed roller 9 for dividing the portion of the fibrous material into individual fibers and a spinning rotor corresponding to a torsion mechanism. The take-off rolls 10, AND to remove the yarn 12 from the rotor, and the receiving rotor # 13, which is a winding mechanism, are driven by separate motors 14-16, respectively. The engines 15 and 16 are connected to the generators 17-18, respectively, and the engine 14 is connected to the generator 19, driven by a variable-speed electric motor 20. Generators 17, 18 and 21 are driven by variable-speed drives 3. When, water 3 directly causes the shaft to rotate

generator 18, which is the source of the high frequency energy of the engine 15, which causes the spinning rotor to rotate at a very high speed. The actuator 3 drives the gearbox 22 for driving the generator shafts 17 and 21 at correspondingly reduced speeds to supply electricity to the engines 16 and 23. The motor drives the motor I and the combed roller 9 at a speed corresponding to the output signal generator 19. The productivity per unit of time is determined by the speed of removal of the yarn from the spinning rotor, and the required number of twists attached to the yarn by the number of revolutions

rotor per unit of time and the rate of removal of yarn from the rotor. The pulse generator, which generates a constant pulse in accordance with the speed of the pickup roller 24, is mounted on the gearbox 22. The frequency of the output signal of the variable frequency source 25 is adjusted in the usual way in accordance with the command signal from the output of the computing unit. The speed of the variable speed drive 3 is adjusted according to the output signal of the variable frequency source 25, as a result, the speed of the drive of the open spin frame can be adjusted.

In this device, the spin speed deviation is minimized, as a result of which stable and uniform operation can be ensured.

product quality.
