    Device for feeding yarn with a constant adjustable tension, for use in weaving machines, wherein - in order to limit the dust settlements within the device itself - closed spaces are created inside the yarn winding drum and an air stream is produced in order to prevent the settlement of dust between said drum and the remaining parts of the device.

    专利说明:

    The invention relates to textile activity and relates to devices for the temporary accumulation of thread during the feeding mainly to a loom.
    A device is known in which the yarn guide is made like an impeller of a fan, which makes it possible to free the surface of the drum and other components from fluff and dust I.
    However, this device does not prevent the accumulation of dust in the cavity of the drum.
    The closest to the present invention is a device for temporary accumulation of the yarn during the feeding, containing a hollow stationary yarn accumulation drum mounted by means of the Bearings on the axis of rotation, on which the yarn guide is also rigidly fixed to wind the yarn on the drum, which is located coaxially with the axis of rotation. at the same time, a whole with it and a tubular thread guide extending from it, mounted on the axis of rotation with an inclination relative to it and stationary relative to the drum a disk for displacing the coils threads on the drum working surface, means for controlling the number of threads of the threads on the drum, connected with the drive of the yarn guide, and means for contacting the end cover of the drum for braking the convergent thread 2.
     The known device does not preclude the deposition of dust in the cavity of the drum, which reduces the reliability of its work, since the deposition of dust on the working nodes of the device violates their function.
    The purpose of the invention is to increase the reliability of the device by limiting the deposition of dust in the cavity of the drum.
    The goal is achieved by the fact that in the device for temporary accumulation of the thread during feeding, mainly to a weaving machine containing a hollow fixed yarn accumulation drum mounted by bearings on the axis of rotation, on which the thread guide is also rigidly fixed to wind the thread on the drum which is located coaxially with the axis of rotation and the barrel, which is integral at the same time, and the tubular thread guide extending from it, mounted on an axis of rotation with an inclination, are relatively and fixed to it A disc for displacing the threads on the working surface of the drum, means for controlling the number of threads on the drum, connected with the drive of the yarn guide, and contacting the end cover of the drum with means for burning) a converging thread, the drum is made in the form of a closed box on which From the side of the winding thread, the rods are fixed along the perimeter, facing the disk and forming an additional working surface for receiving the initial threads of the thread, and the disk has the shape of a truncated cone, the larger base of which is in It engages with the ends of the rods, and the smaller one is connected with the axis of rotation, the exit of the thread guide is located opposite the rods.
    The disk has holes on the periphery of its larger base for engagement with the ends of the rods and through-slots made on the side surface of the cone for passing the air flow.
    In addition, on the barrel of the yarn guide CO, on the side of its drive, behind the tubular thread guide is a rigidly mounted casing having the shape of a truncated cone, covering the zone of rotation of the thread guide.
    FIG. 1 shows the device in section; in fig. 2 is a disc for displacing the threads of the thread, front view.
    The device for temporarily accumulating the threads during the feed contains a bearing body 1, in which a hollow fixed thread-storage drum 4 is mounted by means of bearings 2 on the axis 3 of rotation. On the axis 3 a thread guide is rigidly fixed, winding the thread 4 onto the drum 4 fixed in cases 1 bearings 5 and having a barrel 6 which is integral with it and a tubular yarn 7 extending from it. The axis 3 is mounted by means of a bearing 8 with an inclination relative to the axis 3 of a disk 9 for displacing the threads of the thread along the working surface 10 of the drum 4.
    The device has a means 11 of a known type for optically controlling the number of turns of the thread on the drum 4. The means 11 is electrically connected to a yarn guide drive (not shown). With end cap. 12 of the drum 4 contacts the means 13 for braking the convergent thread. The drum 4 is made in the form of a closed box on which rods 14 are fixed along the perimeter on the winding side of the thread, facing the disk 9 and forming an additional working surface 15 for receiving the initial turns of the thread. The disk 9 has the shape of a truncated cone, the larger base of which has holes 16 that engage with the ends of the rods 14, and the smaller one is connected to the bearing 8 and through it with the axis 3. The output 17 of the thread guide 7 is opposite the rods 14. On the side surface of the disk 9 through slots 18 are made to pass the air flow. On the barrel 6, from the side of its drive, a rigidly mounted casing 19, having the shape of a truncated cone, encompasses the zone of rotation of the thread guide 7.
    The drum 4 is prevented from rotating by a system of magnets 20, one of which is fixed to the drum and the other to the body. With counter. The balancing weight 21 is fixed to the side of the barrel 7 on the barrel 6. The drum base is closed by a rat 22. The thread is guided through the inlet 23 and removed through the outlet 24 fixed on the position-adjustable bracket 25 mounted on the holder 26. As the rods 14 are hooked from the hole 16, the disk 9 cannot rotate and only oscillates about the axis 3. The bracket 25 also holds the means 13 for braking the thread.
    The device works as follows.
    When the barrel rotates, 6 transfers the rotation to the thread guide 7 and it winds the thread onto the working surface 15 formed by the rods 14. The disk 9 then swings the thread 9 from the additional working surface 15 to the main 10, from which the thread is further pulled as consumption through exit 24.
    0 The rotation of the yarn guide is carried out as the thread is consumed and is controlled by means 11.
    This device structure
    5 eliminates the ingress of dust into the cavity of the drum 4.
    When the thread guide 7 rotates at a speed of 200-2800 rpm, it together with the balancing weight
    0 (counterweight) 21 operates as a centrifugal fan, which sucks air from the space surrounding the barrel 6 and forces it through the slots 18 of disk 9 onto
    5 drum 4 (direction, air flow is shown by arrows). This airflow also prevents dust and fuzz from depositing on rods 14 and disk 9.
