    The invention relates to a textile industry and can be used to accumulate a yarn before feeding it to a textile machine. The purpose of the invention is the elimination of false actuations of the rotational drive. When the filament is fed to the drum as measured by the photosensor receiver, the luminous intensity is relatively large, therefore the rotational drive operates at an increased number of revolutions. As the amount of accumulated filament increases, the light intensity measured by the receiver decreases as the rotational speed of the drive decreases. However, due to the constant winding of the thread, the luminous intensity is again increased with a new increase in the number of revolutions of the rotational drive. With a periodic increase and decrease in the number of revolutions of the drive during the winding and unwinding process, it is not necessary to stop the rotational drive. 5 hp ff, 4 ill. § SU)

    The invention relates to the textile industry and can be used to accumulate a yarn before feeding to a textile machine.
    The purpose of the invention is the elimination of false actuations of the rotational drive.
    FIG. 1 shows a device for feeding a yarn to a textile machine; general view; in fig. 2 - the same, front view; in fig. 3 — drum, longitudinal section in the zone of the point of entry of the filament and photo sensor; in fig. 4 - the same cross section.
    The device for feeding the yarn to the textile machine contains a motor 2 flanged to the housing 1, which is a rotating drive. Its shaft is rigidly connected to the holder 3 of the peephole 4 for the thread. The incoming thread F is directed to the central channel of the shaft of the electric motor 3 and further to the eye 4 for the thread (the direction of rotation of the holder is shown by the arrow in Fig. 2). The motor shaft 2 is the holder of the drum 5, which in this embodiment is stationary. The drum 5 has an outer side surface 6, which transforms from the coiling side of the device to the end wall 7. The outer surface of the drum from the coiling side of the thread ends with a barrel-shaped annular head surface 8, which is equipped with brushes 9

    brake ring 10, placed on the console 11. The console 11 is fixed by means of an annular flange housing 1.
    The end of the cantilever 11 facing the annular head surface has an eye 14 on the bent portion 13 for squeezing the thread, located coaxially with respect to the axis of the bar 5 of the banana 5 and at a certain distance
    I in front of the annular head surface 8.
     The end of the outer side surface 6 facing the holder 3 of the eye 4 4 passes through the annular neck 15 into the conical expansion 16. The elevation angle of this conical expansion is about 45. To conical

     The filament surface of the drum I-5 is formed by rods 18 with the same distribution over the angle I, partially placed j in the grooves 19 of the outer side surface 6 and protruding on it. . I Passing approximately throughout: the axial length of the drum 5, the rods 18 I form on their faces: to the col-; at the cost of the throat 15 ends of its own I angular throats 20. Throat angle-; guilt is a little less than 180. The ends 21 of the rods 18 adjacent to the angular neck 20 enter the slots 22 of the conical expansion 16 that extend from the grooves 19 and the rods 18 rest with the ends 21 on the directed
    A cantilever 11 accommodates a photosensor 27 extending along the entire length of the accumulation of the drum 5. The accumulation length is shorter than the length of the drum 5.
    The photo sensor 27 has a housing 28, which is the holder of a source 29 of a sieta and a receiver 30 of a photo sensor.
    The light source 29 and the receiver 30 are located parallel to the axis of the drum 5. The light source 29 consists of consecutively arranged LEDs 31 emitting modulated, power-controlled light. Each LED 31 corresponds to its own sensitive element 32 of the receiver 30.
    Opposite the photosensor 27 on the drum 5 a carrier 33 is placed, which has an arcuate shape and consists of two optical fibers 34 arranged in a row placed between plates 35 and 36 made of aluminum. The end surfaces 25 34, ZD of the optical fibers are oriented towards the thread-accumulating surface of the drum 5. Accordingly, one end surface 34 of each optical fiber 34 faces the light source 29, and the other end surface 34 is offset to the receiver 30 of the photosensor 27 in the circumferential direction.

    The light intensity first measured by the receiver of the photosensor 27 is relatively large, so the rotational drive operates at an increased number of revolutions. As the amount of stored thread V increases, as measured by the photosensor receiver 27, the light intensity decreases with a simultaneous decrease in the speed of rotation of the primite disk 24 through the adjusting screw 26, which is also accessible from the side of the annular head 8.

    to break the thread.
     If the light intensity of the source 29 of the light of the photosensor 27 increases, then the light threshold is shifted simultaneously. Due to this, an increase in the rotational speed occurs, leading to an increase in the stock of the yarn on the drum 5.
    When using a rotating drum 5, several similar carrier elements 33 should be positioned one after the other around the circumference of drum 5. The distance between them should be smaller than between the light source and receiver of sensor 27, therefore in any position of rotation of the drum 5, the photo sensor 27 is in the ready for operation state.
    A photo sensor can also be used that does not conduct along the accumulation length of the drum. In this case, the photosensor should be made resettable with respect to the thread storage surface of the drum. Then the device operates on the principle of start-stop operation.
