Definitions

  • the invention relates to a wire running device according to the preamble of claim 1.
  • wire brakes are controlled by brake rollers ( DE 40 35 862 A1 ) or brake bands ( EP 309 381 A1 ) or lever elements ( DE 34 36 187 C2 ) or. ( DE 23 18 884 C2 ), wherein the known devices are designed so that they counteract the wire run. It is known to adapt the braking force of such wire brakes the desired Drahtzug.
  • a wire running apparatus for feeding a wire in a feed direction, comprising a driven brake roller adapted to counter the wire run when feeding the wire by rotating in a braking direction, wherein a pressure roller biased against the brake roller drives the wire against the brake roller presses so as to produce a frictional engagement with respect to the pressed against the brake roller by the pressure roller.
  • the invention is based on the idea to use the already existing brake roller to return wireless. This happens because the wire is pressed against the brake roller by means of a pressure roller. Due to the resulting friction, the brake roller can then be used to return any wireless, because the brake roller is anyway drivable against the feed direction. Thus arises during the winding process game in the wire, the brake roller can therefore be used to remove this game again.
  • the outer circumference of the brake roller has a frictional engagement material, which is designed to generate a static friction with the wire pressed by the pressure roller. This stiction causes the brake roller not only has a braking function, but can move the wire in the braking direction.
  • the frictional engagement material is a vulcanized rubber material.
  • vulcanized rubber material Of course, other materials are conceivable as long as they are suitable for the purpose of the invention.
  • the pressure roller is biased against the brake roller so that it presses the wire against the brake roller.
  • a biasing device is provided which biases the pressure roller in the pressing direction against the brake roller.
  • This may be a compression spring, of course, other possibilities are conceivable, for example, a pneumatic cylinder or a linear drive or the like.
  • the brake roller comprises at its periphery a wire guide groove.
  • the pressure roller has a peripheral region, with which it dips into the wire guide groove of the brake roller.
  • the brake roller is rotationally driven both in the braking direction and in the opposite direction of the braking direction.
  • the brake roller can support the running movement of the wire as well as decelerate or even lead back wire when a wireless should have formed.
  • the wire running device according to the invention can be installed in winding devices, so that the object is achieved by a winding device, wherein the winding device comprises a wound with wire wound body, a wire and a wire device described above and a particular wire feed or Draht Resultssdüse formed wire guide, which is arranged between the winding body and wire running device and the guided through the wire running device wire feeds the winding body.
  • FIGS. 1A and 2A show a winding device from the front (1A) and from the side (2A).
  • a winding body 7 is to be wound with a wire 2.
  • the wire 2 from a wire supply behind or alternatively also before the winding device (not shown) via a braking device, comprising a brake roller 4 and a pressure roller 5, a guide roller 3 is supplied.
  • the wire guide 6 which is exemplified as a wire feed nozzle 6, as shown).
  • the wire guide 6 is controlled so that the wire 2 is wound in the desired manner on the winding body 7.
  • the feeding direction of the wire is designated by the arrow R.
  • the wire running device 1 is intended below at the FIG. 1B that the cut A of the Figure 1A corresponds, will be explained in more detail.
  • the wire 2 is fed via a guide element, for example by a pipe section which ends immediately below the brake roller 4, the brake roller.
  • the pressure roller 5 presses the wire 2 with a pretensioning device 8 in the pressing direction P2 against the brake roller 4
  • the pretensioning device 8 has two compression springs; However, it is also conceivable pretensioners 8, which comprise tension springs, linear drives, pneumatic cylinders or similar devices. By pressing the pressure roller 5 to the brake roller 4, a frictional engagement of the wire 2 with the brake roller 4 is generated.
  • the brake roller 4 can be driven both in the braking direction and in the feed direction R, the supply of the wire 2 can both supported and braked and it can even be returned to the wire 2, if a wireless between brake roller 4 and bobbin 7 should have formed.
  • the wire 2 is fed via a deflection roller 3 to a controllable wire feed nozzle 6, in order subsequently to be wound on a winding body 7.
  • FIG. 1B the embodiment of the pressure roller 5 immersed in the wire guide groove 40 of the brake roller 4, which is based on the FIG. 2B is explained in more detail.
  • the FIG. 2B shows the outer portion of the brake roller 4, whose outer periphery is designed as a wire guide groove 40, 41, 42.
  • the wire 2 is guided along the brake roller 4.
  • the wire guide groove has (viewed from the brake roller center [top]) a flat or beveled bottom 40 on which the wire 2 rests.
  • this wire guide groove 40, 41, 42 engages the peripheral portion 50 of the pressure roller 5 and presses the wire 2 against the bottom 40 of the wire guide groove.
  • the cross section of the peripheral region 50 is shown rectangular. This is a preferred embodiment of the peripheral region 50 of the pressure roller 5. However, it is also conceivable that the cross section is slightly conical. However, the prerequisite is that the wire 2, which is pressed by the pressure roller 5 against the brake roller 4, can not fall out of the wire guide groove 40, 41, 42. In the FIG. 2B the "lower" part of the wire guide groove is also shown rectangular. This section could also be designed as the outer region of the pressure roller 5 slightly conical. The "upper" portions of the wire guide grooves 41a, 41b are more chamfered. This should serve to guide the sections to each other when merging pressure roller 5 and brake roller 4.
  • the brake roller 4 and the pressure roller 5 in the wire guide groove 40, 41, 42 are shown without tolerance to each other.
  • the tolerance at one side is less than half the diameter of the wire 2.
  • the clearance between the pressure roller 5 and the brake roller is less than 1/20 mm.
