Definitions

  • the invention relates to a wire brake device with a brake arrangement in which the wire running from a wire supply can be braked and with a wire tension sensor, the brake arrangement consisting of a single brake device with two brake elements receiving the wire between them and at least one brake element against the other Brake element is arranged such that it can be guided and is coupled to a drive which is connected on the input side to the output of the wire tension sensor.
  • a wire brake device defined in this way is known from the Swiss patent specification CH-A-0 498 766.
  • the braking elements here consist of two rollers which are driven against the running direction of the running wire, one roller being pressed against the other roller by means of a lifting magnet in order to adjust the pressure. Because of the relatively low braking effect, in particular when passing thin wires, this wire brake device can only be readjusted to a small extent with regard to the achievement of constant wire tensile stresses.
  • a braking device for generating a constant winding tension is known, the braking elements of which are formed by individual pressure rollers which are pressed against one another in connection with endless belts.
  • the brake arrangement consists of a pre-braking device and a main braking device.
  • the pre-braking device is formed by a brake wheel covered with felt on the outside, around which the wire running out of the wire supply is wound.
  • the brake wheel of the pre-braking device is driven counter to the direction of the wire, and the wire is pressed against the outer circumference of the brake wheel of the pre-braking device by means of a pressure roller, whereby an overall braking effect is achieved.
  • the wire is guided by the pre-braking device via a further brake wheel of the main brake device, the wire being wound around this brake wheel several times.
  • the brake wheel of the main brake device is also driven counter to the direction of the wire and can be braked by means of two brake disks that engage it laterally.
  • each braking element contains an endless brake band guided by two deflection rollers arranged offset along a straight path of the wire and an actuating plate connected to the drive, wherein the actuating plates can be moved towards or from one another by means of the drive.
  • This configuration of the braking device has the advantage that at one Wear of the braking element in the braking area can be restored by simply adjusting the endless brake band.
  • the brake band can be made of a material that causes a sufficient braking effect. In many cases, however, it is advantageous if the brake band has a brake lining on its side facing the wire. With such a configuration of the brake band is its material properties regardless of that of the brake pad, which therefore only needs to be designed for an optimal braking effect.
  • felt As a material for the brake pad, felt has proven to be advantageous for thin wires, which forms the brake pad as a felt layer.
  • the brake arrangement contains a brake force multiplier with two further deflection rollers, via which the wire is passed several times between the brake elements.
  • the drive is an electromagnetic drive which is supplied with an electrical output signal of the wire tension sensor on the input side.
  • the wire tension sensor can be, for example, a sensor according to DE-A1-23 31 987.
  • the figure in the figure is the essential part in connection with the invention of an embodiment of the wire brake device according to the invention in a Winding machine shown in a perspective view.
  • the running wire 1 is accommodated in a wire supply 2, which is held on the winding machine in a manner not shown. After it has emerged from the wire supply 2, the running wire 1 arrives in a braking device 3 which has two braking elements 4 and 5.
  • Each of the two brake elements 4 and 5 contains a brake band 6 and 7, which is guided around two deflection rollers 8 and 9 or 10 and 11.
  • the deflection rollers 8 and 9 or 10 and 11 are offset along a straight path 12 of the running wire 1, arranged one behind the other in the wire direction.
  • each of the braking elements 4 and 5 includes an actuator plate 13 and 14, respectively; both actuating plates 13 and 14 are coupled to an electromagnetic drive, which is accommodated in a housing part 15 of the wire brake device in a manner not shown.
  • the actuating plates 13 and 14 can be moved towards or away from one another in the direction of the double arrows 16 and 17 by means of the electromagnetic drive, as a result of which the braking effect on the wire 1 running between the braking bands 6 and 7 is increased or reduced.
  • the brake bands 6 and 7 consist of a suitable carrier material to which a felt layer is applied as a brake lining, in such a way that the felt layer lies on the side of the brake bands 6 and 7 facing the running wire 1, respectively.
  • the braking device 3 is assigned a braking force multiplier, which contains further deflection rollers 18 and 19. About these deflection rollers, which have no special drive, but are freely supported on axles 20 and 21, the wire 1 entering the braking device 3 from above is looped several times, so that the outgoing wire 1 has several sections runs between the braking elements 4 and 5. The braking effect is correspondingly multiplied in accordance with the number of wire sections located simultaneously between the braking elements 4 and 5.
  • the deflection rollers 8 and 10 of the braking elements 4 and 5 can be driven in the direction of the arrows 22 and 23. This allows the wire to be withdrawn if necessary. Such a wire retraction is required, for example, if a wireless could result when the coil is manufactured.
  • a wire tension sensor 24 Downstream of the braking device 3 in the running direction of the wire 1 is a wire tension sensor 24, which is equipped in a known manner with two spatially fixed rollers 25 and 26 and a sensor roller 27. From the wire tension sensor 24 - if this is designed in detail, for example, as described in DE-A1-23 31 987 - an electrical signal is emitted to the electromagnetic drive of the brake device 3, which is not shown in the remainder, which causes the actuating plates 13 and 14 are adjusted so that a corresponding braking effect is achieved so that a predetermined wire tension is maintained.
  • the running wire 1 runs through a wire laying device 28, which, in the rest of the way not shown, can be moved in the direction of the double arrow 29 parallel to an axis 30 of a coil former 31, as a result of which the coil former 31 produces electrical coils have individual turns applied side by side.
