Definitions

  • the present invention relates to a winding device for threads, consisting of a bobbin roller supported by a rotary bearing and a drive roller, the rollers being arranged parallel to one another and with their axes of rotation lying in a substantially vertical plane one above the other, one of the rollers being one of the mentioned plane and to the axes of rotation of the rollers substantially vertically movable support body in elastic bearings is carried out such that with the increase in the amount of thread wound a relative displacement of the drive roller and the bobbin roller against the pressure of the rollers pressing against each other, and one of the Rolling is pivotable about a pivot axis perpendicular to the plane mentioned, in order to maintain the parallelism of the axes of rotation of the two rollers during the entire winding process.
  • a device of this type is known from FR-A No. 2329575 and DE-A No. 2649555.
  • This device makes it possible to keep the axes of rotation of the two rollers approximately parallel to one another during winding despite the increasing weight of the wound amount of thread and the necessary one-sided elastic mounting of the bobbin roller biased against the drive roller and driven by this surface drive. This has a favorable effect on the quality of the finished coils in terms of taper and uniformity.
  • the drive roller is arranged so as to be pivotable about said pivot axis, said drive roller having an imaginary cutting line between an imaginary vertical plane which bisects the length of the thread bobbin transversely or along its length, and an imaginary horizontal plane which at least approximately affects the underside of the drive roller coincides.
  • the carrier roller and the drive friction roller can also be adjusted to one another in such a way that they assume an exactly parallel position in the case of half-wound coils, i.e. that at the beginning of the winding process, for example, the carrier roll with its free end is slightly inclined towards the friction roll and at the end of the winding process it is directed somewhat away from the latter.
  • the object on which the present invention is based is to further improve a device of the type mentioned at the outset in such a way that it is less susceptible to vibration and thus can form high-quality thread spools, irrespective of the thread quantity to be wound and the individual thread properties.
  • a coupling device actuated by the relative displacement forcibly controls the pivoting angle of the pivotable roller.
  • FIG. 1 shows a bobbin roller 11 on which there are four bobbins 12 formed or formed by winding.
  • the roller 11 is rotatable about its axis of rotation 13.
  • a drive friction roller 14 is fixedly mounted in bearings 15 and rotatable about its axis of rotation 16. The arrangement is such that the two axes 13 and 16 lie in a vertical plane.
  • the roller 14 is driven by a motor 17.
  • the left end of the bobbin roller 11 in Fig. 1 is a free end. This is kept free so that the finished spools 12 can be easily removed men can be.
  • the roller 11 is elastically supported in a rotary bearing 21 for reasons of vibration.
  • the latter is attached to a carriage or support body 22 which is slidably arranged in guides 23. These lie parallel to the plane defined by axes 13, 16. The displacements of the carriage 22 thus also take place parallel to this plane.
  • the support body 22 can be designed to slide on the guides 23 or to be movable by means of rollers.
  • the pivot bearing 21 is mounted on the carriage 22 in such a way that it can be pivoted about a pivot axis 24 carried by the latter.
  • the pivoting movements also run parallel to the plane defined by the axes 13, 16.
  • the carrier roller 11 can thus also be pivoted about the pivot axis 24 in this plane.
  • the rotary bearing 21 is also connected to an actuator 26 mounted on a rotary element 25.
  • the rotating element 25 is also carried by the support body 22. It can be rotated about an eccentric axis 28 by means of a control member 27.
  • the control member 27 is coupled via a swivel arm 29 to a fixed part of the winding device.
  • the element 25 forms the coupling point at which the control member 27 is coupled to the actuator 26.
  • the bobbin roller 11 together with the rotary bearing 21 and the carriage 22 are constantly pressed against the drive roller 14. This can happen, for example, in such a way that the slide 22 is continuously exposed to a corresponding pressure.
  • the motor 17 drives the roller 14.
  • the roller 11 As a result of the aforementioned pressure to which the roller 11 is continuously exposed, it is entrained by the roller 14.
  • the gradual enlargement of the bobbins 12 during the winding process causes the roller 11 to move downwards as the carriage 22 is displaced.
  • the coils 12 grow, their weight also increases. This results in a slight bending of the roller 11 and a slight yielding of the bearing 21, since this is designed as an elastic bearing.
  • the free end of the roller 11 is moved slightly downwards. Although this is generally only a few millimeters at most, this deviation from the parallel position of the rollers 11 and 14 is sufficient for the coils 12 thus formed to have the disadvantages mentioned at the outset.
  • the present invention in the embodiment according to FIG.
  • a coupling device 20 which comprises the parts 25 to 28 and inevitably brings about a parallelism of the rollers 11 and 14.
  • the carrier roller 11 moves downwards as a result of the growing diameter of the coils 12, the slide 22 and thus also the eccentrically mounted rotating element 25 moves downwards.
  • the control member 27 pivots clockwise about the axis 32 and also causes the rotary element 25 to rotate about the axis 28 in a clockwise direction.
  • This rotation of the element 25 moves the actuator 26 downward with respect to the carriage 22.
  • the pivot bearing 21 is also pivoted clockwise about the axis 24.
  • the setting and the eccentricity of the rotating element must be adapted to the increase in the spool weight in such a way that the parallelism is maintained in all phases of the winding process.
  • different distances of the center of the rotary element 25 from the axis of rotation 28 and / or correspondingly selected starting positions of the rotational position of the element 25 must of course be selected.
  • the influence of a contact force on the drive friction roller that varies greatly during the build-up of the coil can also be corrected in this way.
  • Fig. 2 relates to an arrangement in which the size of the pivoting of the control member 27 is adjustable in a simple manner.
  • the carriage 22 in turn carries the rotary bearing 21 and the rotary element 25 on a shoulder.
  • the latter is in turn mounted eccentrically and rotatable about the axis of rotation 28.
  • the actuating member 26 connects the element 25 to the rotary bearing 21 and causes it to pivot about the pivot axis 24.
  • the control member 27 is fixedly connected to the rotary element 25 and can be pivoted with it about the axis 28.
  • a roller 33 is attached to the control member 27, which roller is intended to move along a control cam or link 34 when the carriage 22 moves up or down.
  • the control member 27 is continuously pressed against the link 34 by a spring 35.
  • the parts 25, 26, 27, 33, 34, 35 form a coupling device 30.
  • the link 34 causes the control member 27 to pivot clockwise.
  • the rotating element 25 also rotates in the same sense, as a result of which, when the element 25 is in the drawn position, the actuating element 26, based on the carriage 22, moves downward.
  • the pivot bearing 21 is thus pivoted clockwise about the pivot axis 24.
  • control curves 34 of a suitable shape.
  • the position of the control cam 34 can be changed by slidably attaching a plate 38 supporting it to a fixed part of the winding device.
  • a correspondingly shaped slot can also be provided in a manner known per se, in which a sliding block fastened to the control member slides instead of the roller.
  • FIG. 3 shows a further possibility of controlling the position of the carrier roller 11 with respect to the drive roller.
  • the coupling device 40 is realized by a pneumatic or hydraulic arrangement.
  • the rotary bearing 21, which in turn is supported on a slide 22 by a pivot axis 24, is connected to a piston 43 provided in a cylinder 42 via an actuating member 41 designed as a piston rod.
  • actuating member 41 designed as a piston rod.
  • the control valve 45 is controlled by means of the control member 47.
  • the line 44 is flexible so that the carriage 22 can move with respect to the regulating valve 45 which is firmly connected to the device.
  • the control member 47 is moved with the carriage 22 and exerts a regulating effect on the valve 45.
  • This regulation is such that in the roller arrangement shown in FIG. 1, the pressure in the cylinder 42 is increased when the carriage 22 moves downward. This results in a pivoting of the rotary bearing 21 about the pivot axis 24 in the clockwise direction and thus a compensation of the lowering of the bobbin roller 11 during the winding process with its free end downward.
  • FIG. 4 A still further embodiment of a winding device according to the invention is shown in FIG. 4.
  • This in turn has a drive friction roller 64 with a motor 17 driving it.
  • Roller 64 and motor 17 are rotatably supported in a support frame 51.
  • the frame 51 is pivotable about the pivot axis 52 and carried by this.
  • a coil carrier roller 61, on which coils 12 are formed, is in turn elastically supported in a rotary bearing 21.
  • the axes 13, 16 of the rollers 61 and 64 are again in a substantially vertical plane. In parallel to this plane are guides 23 formed by guide rails, in which a carriage 22 can be moved essentially parallel to this plane.
  • a two-armed lever 54 is slidably and pivotably mounted in a slot 55 in the carriage 22. Near its other end it is pivotable about a shaft 56 which is assembled with a part fixed to the device.
  • the bolt 53 and an axle 57 on the short arm of the lever 54 are connected by a joint designed as an actuator 58.
  • the axis 57 can be attached to the short lever arm at any selectable distance from the shaft 56 in any known manner.
  • the parts 53 to 58 form a coupling device 50 and the axis 57 is the coupling point at which the control member 54 is coupled to the actuator 58.
  • the carrier roller 61 and the rotary bearing 21 with the slide 22 move downward.
  • the lever 54 is pivoted counterclockwise around the shaft 56, whereby the axis 57 is moved upward.
  • the actuator 58 thus lifts the bolt 53, whereby the support frame 51 and thus the drive friction roller 64 are brought back into a position parallel to the support roller 61.
  • the selectable, variable distances between the shaft 56 and the axis 57 serve to adapt to different types of yarn or to the selected winding density of the bobbins 12.
