    (5) METHOD OF MANUFACTURING TUBULAR PRODUCTS AND DEVICE FOR ITS IMPLEMENTATION
    . I.
    The invention relates to the textile industry, in particular to methods for producing tubular products, and devices for carrying out these methods.
    A known method of manufacturing tubular products is that a portion of the fiber is pre-wound onto the drive, after which the fibers are rewound to move-; axially extending core by rotating around the latter. accumulator.
    However, the method is inefficient.
    The purpose of the invention is to increase the production / productivity ",
    The goal is achieved in that in the method of manufacturing tubular products, namely, a portion of the fiber is pre-wound onto the drive, after which the fiber is rewound onto an axially displacing core by rotating around the latter |
    when rewinding the fiber from the accumulator to the latter, the subsequent portion of the fiber is wound, and when it is rewound onto the core, the accumulator is reversed. A device for carrying out the method is known, comprising a core holder for axial displacement, mounted in the hollow accumulator coaxial to the latter, a fiber guide, a device for rotating the accumulator and fiber guide, and means for feeding the fibers to the accumulator with a fixedly mounted spur 2.
    To improve performance, a device containing a core holder with means for axially moving it, mounted coaxially to the latter in the hollow storage 20,. fiber guide, device for rotating the drive and fiber guide and means for feeding the fiber to the drive with a stationary spool, equipped with a device for receiving a subsequent portion of the fiber placed between the drive and the spool and having a hollow fiber turn holder mounted coaxial to the drive, and the drive installed with the possibility of reverse rotation and has on the outer surface a means for ensuring the movement of the fiber on the surface of the storage ring. The means for moving the fiber over the surface, however, the pitle is the rollers mounted thereon. The device is equipped with a fixture for fixing the wound fiber on the core while changing the direction of rotation of the storage ring, having pressure and means for moving it. FIG. 1-4 tribute, 1 schematic diagrams of operation of the device for carrying out the method j in FIG. 5 shows the device | OSN, FIG. 6 is the same, top view, in FIG. 7 - part of the device in FIG. 8 — the clamp in FIG. cross section; FIG. 10 - a means of moving the clamp. The device comprises a core holder .1 and a hollow drive 2 rotating with an angular velocity a) j. A spiral 3 of fibers 4 is wrapped around the rollers of the hollow storage unit 2. A spiral 5 of fibers k is also wound onto the core 1. This operation occurs when rotating in the clockwise direction of FIG. L After the turn of the hollow accumulator 2 turns on the helix 3 and 5, the turns of the fibers are wound. When a certain number of turns are reached, the winding direction changes. The second operation (Fig. 2) occurs when rotating in the direction opposite to the clockwise direction. The hollow accumulator 2 rotates at the same angular velocity Oij in the opposite direction. Rotated in the opposite direction is provided in the form of that
    The deflector 1, on which the fibers are wound, is subjected to an axial feed, the speed of which is usually constant. If in both directions the same course of the spiral turns must be observed, then the rotation speed. At the same time, for the ratio of the angular velocity, the equation

    And R i, 1 in both directions should be the same. In the winding direction (Fig. 2), the fibers are removed from the inner surface of the helix 3 and deposited onto the core 1. Now the fiber C moves back to the spool 6 at a speed dependent on the angular velocity and also on the difference between the radii of the hollow accumulator 2 and the core 1. In FIG. 3 shows the rotation of the hollow accumulator 2 and the hollow holder 7 turns of fibers in the direction opposite to the clockwise direction, and FIG. they rotate clockwise. In order to maintain an average speed during the continuous removal of the fibers C with the spool sheath 6, during the reverse winding, a device is used which creates a temporary accumulation of the fibers k. It consists of a hollow holder of 7 turns and a guide B, by means of which the outer helix 9 of fibers is wound on rollers. By rotating the hollow accumulator 2 and the hollow holder 7 turns in the same direction and at a relative speed, which is matched to the corresponding radii, the reverse winding of the fibers can be avoided if the hollow drive 2 and the hollow holder 7 turns rotate clockwise in the Y-direction. The same is valid for the case if they rotate in the opposite direction in the clockwise direction, provided that at the beginning of the process, for example, on the hollow holder 7 turns, there is already a supply of turns. The relative speed may be the same when rotating in both directions, i.e. if the speed ratio between the hollow accumulator 2 and the hollow holder 7 turns is constant in the forward and reverse directions, then the hollow accumulator 2 and the hollow holder 7 turns and guides 10 and 8 can be connected using simple devices, where ( jj is the rotation speed of the hollow holder 7 turns j the speed of rotation of the hollow accumulator 2 | effective radius of the hollow holder 7 turns with rollers | effective radius of the hollow accumulator 2 with rollers.
    clockwise, the number of turns on the hollow holder 7 increases, while the number of turns on the hollow drive 2 decreases, i.e. there is an apparent transmission of turns. Before the consumption of turns on the hollow memory 2, the direction of the rotation changes. When vra-. In the clockwise direction, the number of turns on the hollow accumulator 2 increases, and the number of turns on the hollow holder 7 decreases. The principle of operation shown in (Fig. 3 and, is also characteristic of the device in Fig. 5. At the same time, the turns of the wind are wound on the pipe 11 produced by continuous casting, which is conveyed in the direction of the arrow A on the core 1. The hollow drive 2 has means for moving the fiber along the surface of the accumulator in the form of rollers 12, which are mounted on bearings with little friction resistance so that the rolling resistance increases as little as possible as the load increases with spiral turns 3 and 9. the dimensions of the device PD 2n are layers of turns on the hollow holder of body 7, layers of turns on hollow accumulator 2 when rotating in the clockwise direction. For example, if the direction of winding changes after reaching 100 layers, then on the hollow disk 2 only 50 layers should be applied.With the help of the tension-adjusting device 13, the tension in section 1 can be adjusted to a predetermined constant value, while the speed with which the fibers are fed changes a little, but does not negatively affect the process.
    in section 14 decreases, the adjustment device 13 rotates to accumulate fiber.

    Claims (2)
    [1]
    In order to accumulate the initial turns of fibers in a spiral 9, there is a device for clamping wound fibers on the core when changing the direction of rotation of the drive, having a clamp 19 fixed on the floor holding 8C Performing core 1 and pipe 11 non-rotating gives continuous removal of fibers 15 from spools 16. Adjustment device tension 13 has a frame with rollers 17 arranged against each other. Fibers k are guided between the rollers through the axis of the frame. The tension in region 1 / is adjusted by means of a coil spring 18. If the tension is on the body 7 with the help of the holder 20. The initial fibers are fixed on the clamp 19 with the aid of the element 21. After the necessary number of turns on the hollow holder 7 has accumulated due to the elongation of the clamp 19 is removed and fixed on the plates 22 in the axial direction with the aid of the clamping device 23. After the initial fibers 4 are attached to the surface of the core 1, the winding process is started by changing the direction of rotation. The cutting device 24 cuts off the initial ends of the fibers C, and the clamp 19 is removed. . The clamping device 23 remains in the mounting position on one side of the clamp 19 during the subsequent operation. When removing the L clamp 19 from the plates 22, the first turns of the barrel are tightened around the core 1. The direction of rotation of the device should be changed to the flow rate of the helix 3 or 9. This operation ensures the mutual transfer of fibers from one helix to another to maintain a constant removal rate of the fibers from the spools Rnika 6. In order to never completely use the turns of both spirals, electrical sensors are used, which, after reaching the minimum number of turns of fibers or mini-. The maximum thickness of the spirals transmit a signal to the drive 2 and the holder 7. After reaching the specified minimum number of turns on the drive 2 or the holder 7, the direction of rotation automatically changes .-. The number of turns in one direction depends on the initial Number of turns of the spiral 9. 7. To avoid reduction tensioning the fibers on the core 1 when changing the direction of the winding process, one of the clamping devices 23 is fixed on the outer side of the plate 22 with the help of the guide 25. In this case the clamp 19 is automatically guided the core 1 and is engaged with the opposite clamping device 23. This is how the voltage is compensated for when the winding direction of the fiber is changed. After winding a certain number of turns in the opposite direction, the clamp 19 is automatically removed. The fibers pass through the lip seal 26 into the cylindrical tube 27. The lip seal 26 p is placed on the joint tangent of the core 1 and the roller 12 of the accumulator 2 for this winding direction. In addition to the fibers k, a clamp 19 for guiding the fibers must pass through the lip seal. The seal 26 is longitudinally divided into two strips, each of which with the help of the lining 28 of the replen on the retaining clip 29, made of two parts. The bracket 29 is designed to move around the circumference of the pipe 27. When both parts of the bracket 29 move apart, a gap is formed through which the clamp 19 can pass to be fixed to the core 1. Then, both hours of the brackets 29 are shifted, with the pins 30 entering the holes of the opposite plate half of the seal 26. The fibers C (Figs 5 and 6) are introduced into the thermoplast in a state of softening. The heated rotatable device is located behind the extruder 31. The pipe is finally shaped after being wound. When the core 1 is cooled, an internal solidified layer of pipe is formed, which prevents the fibers from being applied to the core. Such a tube is provided with an inner layer rich in plastic. In addition, in the area of the helix wound on core 1, axially directed ribs are provided, which facilitate the laminar flow of extruded material into the extruding channel. The higher the fiber content in the rotating layer, the more the rotational movement of the extruded material in the extrusion channel is limited, which contributes to laminar flow inside the channel. The core 1 extends over the entire cooling zone 32 (Fig 6) so that the thermoplastic can be installed only relative to the wall thickness, and not relative to the diameter of the pipe. Plastic is added to the fibers to wind the fibers impregnated with plastic onto the core 1. To prevent contamination of the device, instead of roller 6, wetting rollers are used, between which fibers 4 are passed, to which plastic is fed through a duct consisting of two annular cup-shaped elements. The device has a means for moving the clamp, which has an electronic eye with a counter 33, controlling the number of wound fibers, and giving a signal that causes a change in the direction of the winding of the fibers. In this case, the guide 25 on the support 3 is inserted axially along the fibers by means of a magnetic field of the helix 35. The free fibers are captured and pressed to the already wound fibers. Upon subsequent winding, the fibers act on the guide 25, as a result of which the caliper 3 moves axially and presses against the spring 36 until, at the end of the path, as a result of the electrical contact of the helix 35, it causes an instantaneous retraction of the guide 25. Formula 1. manufacture of tubular products, in which a portion of the fiber is pre-wound onto the accumulator, after which the fiber is rewound onto the axially displaced core by rotating around the latter accumulator, aspirants so that, in order to increase productivity, with fiber rewinding nokopitel with the last winding is performed subsequent portions of the fiber, and when rewinding it onto the core is carried out reverse accumulator. 2. A device for carrying out the method according to Claim 1, containing; its core holder for its axial movement, mounted in the hollow disk coaxially to the latter. 9 - 9 fiber guide, device for rotation of the fiber storage device and fiber guide and means for feeding the fiber to the storage device with a stationary mounted spool layer. This is so equipped with a device for receiving a subsequent portion of fiber located between the accumulator and spool holder and having a hollow holder of the fiber turns installed the cracker to the accumulator, and the accumulator is mounted for reversible rotation and has means on the outer surface for providing the fiber movement. over the surface of the accumulator, 3. The device according to claim 2, is about the fact that the means 10 for ensuring the movement of the fiber along the surface of the accumulator are rollers mounted on it. . A device according to Claims 2 and 3, in that it is equipped with a device for fixing the wound fiber on the core with a change in the direction of rotation of the storage device, having pressure and means for its movement.
