    The invention relates to the textile industry and can be used to accumulate a yarn before feeding it to a textile machine. The purpose of the invention is to improve the uniformity of the filament of the yarn to the textile machine. When the filament enters the thread-storage surface of the drum, the first light intensity measured by the photosensor is relatively large, therefore the rotational drive operates at an increased number of revolutions. As the amount of stored filament increases, the light intensity measured by the photosensor decreases with a simultaneous decrease in the number of revolutions of the rotational drive. However, due to the constant reeling of the thread from the drum, the light intensity increases again with a new increase in the number of revolutions of the drive, so the thread is evenly unwound from the drum. 7 hp f-ly, 6 ill.

    This invention relates to the textile industry and can be used to accumulate a yarn in front. feed to the textile machine.
    The purpose of the invention is to improve the uniformity of the filament of the yarn to the textile machine.
    FIG. I shows a device for storing the yarn, general view; in Fig. - 2 - the same, front view; in fig. 3 - a drum, a section in the area of the filament feeding section and a photo sensor; in fig. 4 - the same, cross section; in fig. 5 - drum, longitudinal section, in the area of the filing section of the thread and the photo sensor, corresponding to the second design variant; in fig. 6 -
    drum, cross-section, in the area of the carrier element.
    Presented in FIG. 1-4, the feed device has a motor 2 which is flanged to the housing 1, which is a rotary drive. Its shaft is rigidly connected to the holder 3 peepholes 4 for the thread. The feeding thread F enters the channel of the shaft of the electric motor 2 and further to the eye of 4 for the thread which rotates in the manner shown in FIG. 2 direction of arrow x. The rotational drive refers to a braking device.
    The motor shaft 2 is the holder of the drum 5, which is stationary. Drum 5 has an outer

    the side surface 6, which transforms from the coiling side of the device into the end wall 7, the outer surface of the drum ends on the side of the thread squeeze by a barrel-shaped annular head surface 8 which has a brake ring 0 facing the brushes 9, which is fastened with an annular flange 12 on case 1
    The end of the cantilever 11 facing the annular head surface 8 has, on the bent portion 53, an eyelet 14 for winding a thread that is coaxial with the axis of the drum 5 and is at a certain distance in front of the annular head surface 8.
    The end of the outer side surface 6 facing the holder 3 of the eyelet 4 passes through the annular neck 15 into the conical expansion 16, the angle of elevation of this conical expansion is about 45, the conical expansion section 16 adjacent to the thread holder 3 is parallel to the conical expansion 16.
    The filament surface of the drum 5 is formed by rods 18 located with the same angle distribution, the coaxial ones are partially placed in the grooves I9 of the outer side surface 6 and protrude from it. The rods 18 that extend approximately along the entire axial length of the drum 5 form their ends corner necks 20,. The angle of the neck is slightly less than 180 V. The ends 2 of the rods 22 of the rods 18 adjacent to the angular neck 20 extending from the grooves 19, the slots 2 of the conical expansion 16 enter. Neither 18 are supported by the ends 22 on the radially directed fingers 23 of the installation disk 24.
    Using the central, accessible from the side of the annular head surface 8 of the manipulator 25, the rod 18 with the disk 24 and the fingers 23 can be simultaneously displaced in the shape shown in FIG. 3 direction arrows. However, it is also possible to move only the installation disk 24 by means of the installation bolt 26, which is also accessible from the side of the annular ghalovoy surface 8. The permutation

    The disk 24 in the direction of the arrow causes the rods 18 to rotate around a pivot point near the annular head surface 8. In both cases, the winding conditions in the feed zone of the thread change.
    In console 11, a photosensor 27 extending along the entire thread-accumulating surface of the drum 5 is placed. The accumulation length is less than the length of the drum 5 itself.
    The photosensor 27 has a housing 28, which is the holder of the transmitter 29 and the photodetector 30 of the photosensor. Both transmitter 29 and receiver 30 are located parallel to the axis of the drum 5. Photo transmitter 29,. The sensor consists of a series of LEDs 31 arranged to be adjustable in intensity. Each light emitting diode 3 corresponds to its own sensitive element 32 of the photodetector 30.,
    In the area of the side surface 6 of the drum between the two rods 18 times, the reflecting plate 33 is placed. The light emanating from the transmitter 29 enters this reflecting plate 33 and then deflects to the photo cell receiver 30.
    According to the second variant of the design (FIGS. 5 and 6), instead of the reflecting plate 33, the accumulative element carries only the carrier element 34, which has an arcuate shape and consists of two optical fibers 35 placed one next to the other and placed between the plates 36 and 37 As a material for the plates 36 and 37, it may slug, for example aluminum. The optical fibers 35 are positioned so that their adjacent end surfaces 35, 35 lie freely on the thread-accumulating surface of the drum 5. Considering the circumstances, one square surface 35 of each optical fiber 35 faces the photosensor transmitter 29 and the other side 35 in the direction of the round of the drum 5 is facing the photo sensor receiver 30. In this case, the end portions of the carrier element 34 enter into the slots 18 of two adjacent rods 18 in such a manner that the face nOBejacHOCTH 35, 35 are covered by an outer side surface
    five,
    rods 18. Accordingly, the end surfaces 35, 35 of the optical fibers 35 are also biased with the adjustment of the rods.
    When a rotary accumulator element is used, a number of such arc-shaped parts are arranged one after the other in the direction of the circumferential surface of the accumulative element. The distance from each other must be kept less than the solution cone suitable for the transmitter and receiver of the photo cell. Thus, in each rotational position of the storage element, the photo cell is in a position ready for operation.
    The device operates as follows.
    When the filament F enters the yarn-accumulating surface of the drum 5, the light intensity measured by the receiver 27 of the photo sensor 27 is relatively large so that the rotational drive operates at a higher number of revolutions. As the number of stored threads measured by the photo sensor 27 increases, the light intensity decreases with a simultaneous decrease in the rotational speed of the rotational drive. However, due to the constant winding up of the thread, the light intensity increases again with a new rotational speed rotation. Therefore, it is not necessary to stop the drive completely. Due to this, the occurrence of tension peaks leading to thread wringing is prevented and the thread feeding to the textile machine is ensured uniformity.
    If the light intensity of the transmitter 29 of the photosensor 27 hangs, the light threshold is simultaneously shifted. Due to this, an increase in the number of revolutions occurs, leading to an increase in the margin of the thread on the drum 5.
    When using a rotating drum, several similar carrier elements 34 should be placed one after another around the circumference of drum 5. The distance between them should be smaller than the opening cone between transmitter 29 and receiver 30 of photo sensor 27, therefore in any position of rotation of drum 5 of photo sensor 27 is in ready-to-operate state.
