    The yarn (1) is wound onto a cross-wound package (4) by means of a grooved drum (3), and a first sensor (6) is provided for determining the circumferential speed of a member rotating synchronously at the speed of the traversing yarn. A second sensor (7) determines the position of the yarn (1) on the package (4) in relation to the longitudinal axis thereof, and a correction factor is derived from this determination in order to determine the instantaneous yarn speed from the mean yarn speed obtained from the circumferential speed of the rotating member. …<??>This improves the determination of the yarn speed in textile machines to such an extent that on-line spectrograms can be measured on the latter. Moreover, the accuracy with which the length of the yarn defects is measured is also increased by an order of magnitude. …<IMAGE>…

    The invention relates to the textile industry.
    The purpose of the invention is to improve the measurement accuracy.
    Figure 1 shows the winding unit of a textile machine, side view; figure 2 is the same, front view; Fig. 3 is a block diagram of a microprocessor unit for calculating the speed of movement of the yarn.
    Aj 1 passes through a thread cleaner 2, a threaded (folding) winding drum 3 and is wound on a cross-wound bobbin 4. The circumferential speed sensor of the winding drum 3 frictionally connected to the reel 4 is made in the form of 3 marks put on the side surface of the drum 3, readable by the sensing element 6 Measuring device 7
    the position of the reeled yarn 1 relative to the longitudinal axis of the reel is installed in the area of the trajectory of the reciprocating movement of the yarn. As the meter 7, a photoelectric sensor can be used, for example, one of the extreme positions of the yarn relative to the longitudinal axis of the reel. The meter 7 can also be implemented as a set of photocells (not shown) installed in the zone of the reciprocating motion of the yarn. Preferably, meter 7 is set at the minimum possible distance from the winding drum. The actuator 8 is designed to trim the yarn when defects are detected on it with the help of a thread cleaner 2. Position 9 shows the yarn cut-off mechanism 1.

    The microprocessor unit 10 for calculating the speed of the yarn contains a processor 11, an amplifier 12, an analog-to-digital converter (ADC) 13, a pulse shaper 14, a gain controller 15, and a correction unit 16.
    The output of the sensing element 6 through the driver 14 is connected to the first input of the processor 11, the second input of which is connected to the output of the meter 7, and the third is connected to the output of the ADC 13, the input connected to the output of the amplifier 12. The inputs of the amplifier 12 are connected to the outputs of the regulator 15 and The meter 7. The corresponding outputs of the processor 11 are connected to the inputs of the mechanism 8, 9 of the controller 15, the correction unit 16, the display board 17 and the observer 18. The outputs of the mechanism 8 and the block 16 are connected to the corresponding inputs of the meter 7.
    The method is implemented as follows.
    When winding the yarn, the winding drum 3 rotates and spreads the yarn along the length of the reel 4. The sensitive element 6 captures (reads) the marks 5 applied to the drum 5. The pulse frequency at the output of the sensitive element 6 characterizes the average speed of the yarn 1, which is calculated by block 10.
    The instantaneous speed of movement of the yarn depends on the position of the yarn and. diameter of the reel 4. The range of change of the diameter of the cone reel during winding may vary in a ratio of 3: 1 or more.
    A meter is used to record the position of the yarn. Information about the yarn position and the actual diameter of the reel, calculated by block 10 from the number of revolutions of the drum 3, is used to calculate the instantaneous speed of the yarn. This is done as follows.
    Correction factors are determined experimentally for this textile machine, each of which corresponds to a fixed diameter of the bobbin and the position of the yarn, which can vary within the angle a of the yarn layout. In this case, block 10 implements the algorithm for calculating the instantaneous yarn speed: the instant yarn speed is equal to the product of the average yarn speed and the corresponding correction factor. The experimentally determined correction factors are inserted into the microprocessor unit memory in advance.
    In addition to performing the functions described above, unit 10 is used to control the quality (cross section) of the yarn. Information about the current cross section of the yarn with the thread cleaner 2 is fed to the corresponding input of the unit 10, which generates a signal to the yarn trimming mechanism 8 if the actual yarn section is out of acceptable limits. The processor 11, depending on the nominal yarn number, automatically through the regulator 15 sets the required gain factor of amplifier 12. The signal after amplifier 12 is converted into digital code ADC 13 and after processing controls mechanisms 8 and 9, and if necessary, also a nitron 18. yarn speed information is displayed on board 17.
