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.
- a wire brake device of this type is described in DE-A1-35 36 363.
- 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 on the outside with felt, 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 several times around this brake wheel.
- 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.
- the invention is based on a wire brake device of the type specified at the outset and, according to the invention, provides that the brake arrangement consists of a single brake device with two brake elements which receive the wire between them and that at least one brake element is arranged such that it can be guided against the other brake element and is coupled to a drive. which is connected on the input side to the output of the wire tension sensor.
- a major advantage of the wire brake device according to the invention is that its single braking device enables massless braking of the running wire, because the running wire is not guided around brake wheels, but rather is more or less clamped between brake elements of the single braking device, the strength of the clamping of depends on the desired braking effect.
- the wire tension can be held relatively precisely with a small control time constant in accordance with a predetermined setpoint value in the wire brake device according to the invention.
- Another significant advantage of the wire brake device according to the invention is that it only requires a single brake device, so that the pre-brake device can be dispensed with in comparison to the known brake device mentioned above.
- An additional advantage is that the wire can be inserted into the wire brake device in a simple manner without any aids.
- the braking elements of the single braking device can be designed differently; for example, they can consist of flat brake plates that can be guided against each other.
- each brake 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.
- This configuration of the braking device has the advantage that if the braking element in the braking area is worn, the braking effect can be restored by simply adjusting the endless braking 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 Creativity 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 task often arises to enable a wire retraction.
- This object can be achieved with the wire brake device according to the invention in an advantageously simple manner in that the endless brake band is continuously driven in opposite directions to the direction of the wire by means of a deflection roller.
- 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, for example, be 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 axes 20 and 21, the wire 1 entering the braking device 3 from above is looped several times, so that the outgoing wire 1 with several sections runs between the braking elements 4 and 5. The braking effect is multiplied accordingly 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 can be adjusted to achieve a corresponding braking effect so that a predetermined wire tension is maintained.
- the running wire 1 runs through a wire laying device 28 which, in the manner not shown in the rest, 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.
