    The present invention provides a method and apparatus which enables thread to be wound onto the motor driven storage drum of a thread storage and feeding device for a thread processing machine strictly continuously and uniformly with the aim of ensuring that the thread as wound off the thread supply bobbin is wound onto the storage drum in such a way that variations in the tension of the thread as pulled off the storage drum are eliminated. This is achieved by controlling the number of revolutions of the motor in response to a control signal which is derived from the thread intermediate supply on the drum and the actual thread consumption, i.e., the average speed of the thread leaving the drum.

    The invention relates to automatic devices for storing and feeding the necessary length of yarn to textile machines, having a drum as an intermediate storage ring.
    A control device for measuring the yarn to textile machines with a metering mechanism is known, comprising a metering drum connected kinematically to an electric motor, a measuring unit connected to the input of the control unit, the output of which is electrically connected by means of a speed controller with an electric motor {1 3 the mode of operation of the drive of the measuring drum of the drum, leading to a change in the tension of the thread and an increase in the breakage, as well as to the imposition of thread threads on the surface and make a mistake in measuring drum, making it difficult to rewind it with thread.
    The purpose of the invention is to improve the quality of control of the metering mechanism.
    The goal is achieved by the fact that in a control device of a metering mechanism for feeding yarns to textile machines containing a metering drum kinematically connected to an electric motor, a measuring unit connected to the input of the control unit, the output of which is electrically connected by means of a speed controller with an electric motor, is control contains shaper, integrator, adder, comparator and sawtooth generator, with the output of the measuring unit connected to the first input of the comparator pa and the control means serially connected .bloka shaper and integrator - to the first input of the adder, the second input of which is coupled to byhodbm sawtooth generator, and the output of the adder is connected to the second input of the comparator, whose output is connected to the input of regulator motor speed.
    FIG. 1 is a block diagram of the device; in fig. 2 - principle scheme; FIG. 3 are signal diagrams.
    The device keeps C of FIG. 1) electric motor 1 measuring ba-. raban 2, movable 3 in contact with coiled thread k, rod 5 measuring unit 6, including indicator element 7, mounted on rod 5, reading elements 8 and 9, and sensor 10, control unit 11 containing driver 12,
    integrator 13 adder I, sawtooth generator 15 and comparator 16, speed regulator 1 of electric motor 1.
    The output of the measuring unit 6 is connected to the first input of the comparator 16 and connected in series with the generator 12 and the integrator 13 is connected to the first input of the adder 1, the second input of which is connected to the output of the sawtooth generator 15. The output of the adder 1L is connected to the second input of the comparator 16, the output of which by means of the speed controller 17 is connected to the electric motor 1.
    The read elements 8 and 9 of the measuring unit 6 (Fig. 2) each contain one LED 18 and one photo transistor 19 | which are connected to sensor 10. Shaper 12 is made on diodes 20, 21 and 7.2, capacitor 23 and resistor 24. Integrator 13 contains an operational amplifier 25 with a capacitor 26 in the circuit ob-i
    and the input resistor 27. The sawtooth voltage generator 15 is made on an operational amplifier 28, and the adder 14 - on resistors 29 and 30. Comparator 16 contains an operation1 | onny
    an amplifier 31, the output of which a mediocre driving unit 32 is connected to a communication unit 33, having optic elements 3 and 35 for galvanically uncoupling the control unit 11 and a speed controller 17, which is a thyristor motor control circuit 1.
    The device works as follows.
    When the yarn stock changes on the metering drum 2, the movable ring moves the rod 5 with the indicator element 7 which can block the optical channel of the LED 18 phototransistor 19 of one of the reading elements 8 or 9 and also find it in the middle position. Depending on this, the output of the sensor 10 is formed signal from one of the three
    levels - positive, negative or zero.
    FIG. Figure 3 shows the temporal changes of various signals at times.
    If, up to time point t, a maximum thread reserve (graph A) is present on metering drum 2 (graph A), then this corresponds to a positive signal at the output of sensor 10 (graph c).
    When winding the yarn from the metering drum 2 at time 4, the thread consumption increases (graph A); and when Reaching the minimum stock of the thread on the measuring drum 2, the signal at the output of sensor 10 (plot B) takes a negative value by the time t, and a negative polarity signal of the corresponding duration is generated at the output of shaper 12 (plot C).
    When the thread consumption from the metering drum 2 is stopped and the measured length of the thread is wound on it in the time interval, in accordance with the polarity of the output signal of the sensor 10 (graph B), the output signal of the positive polarity of the specified duration is generated at the output of the imager 12 (graph C).
    The output signal of the imaging unit 12 is integrated by the integrator 13 and is supplied to the first input of the adder Il, the second input of which receives a signal from the output of the sawtooth generator 15. 15. The graph D shows the integrated line and the dashed line the signal from the output of the adder 14, which to the second input of the comparator 16,. comparing it with the output of sensor 10 supplied to its first input.
    If there is a minimum value of the thread margin on the measuring drum 2 at the first input of the comparator 16, the signal has a negative value, and at the second input it is positive. As a result, a higher level signal is applied from the output of the comparator 16 to the input of the speed regulator 17 (graph E) and the electric motor 1 rotates at a maximum number of revolutions, which speeds up the winding process.
    When the maximum value of the thread margin is reached on the measuring drum 2 at the first input of the comparator 16, the signal has a positive value, and at its second input also a positive value of a lower level. In this case, from the output of the comparator 16 to the input of the speed regulator 17, a signal is given at a lower time interval and the electric battery 1 will decrease the number of revolutions jjo of the minimum value.
    TDK-way, the regulation of the speed of the electric motor 1 is carried out depending on the stock of the thread, and the actual consumption of the thread.
    The use of the proposed control device with a metering mechanism for feeding yarns to textile machines allows Improving equipment productivity and product quality by optimally feeding the yarn, reducing breakage and reducing waste.
