Definitions

  • the present invention relates to a device for braking coils rotatably mounted about their axis, of which strand-like material, such as tapes, wires, threads and the like. Can be unwound and, after a positive connection to a drive shaft, these coils can be rewound with the corresponding strand-like material.
  • the force of an electromagnetic field is used for the generation of the braking torque or for the torque transmission, the anchor being a metal ring which can be moved against the spring force and is arranged on the flange side of the coil, via which the magnetic force flow closes when an electromagnet is excited.
  • coil brakes in which the braking torque is already generated by an electromagnet, are known from the internal status of Tecknik, means being available which depend on one another change the excitation current that determines the braking torque of the electromagnet from the coil radius or the coil rotation speed or from the coil weight.
  • the invention is therefore based on the object of finding a way which meets both requirements.
  • This object is achieved in a generic device according to the invention in that an air gap is provided between the armature ring and the electromagnet.
  • This air gap which is advantageously 0.1-1.5 mm in width, preferably 0.2-0.8 mm, allows for active operation, i.e. the unwinding process, with a reduced excitation voltage of the electromagnet, a sufficient control range for the braking force without the jerky holding of the armature ring and thus a sudden stop of the unwinding spool.
  • the invention guarantees that with a correspondingly increased or full excitation voltage in passive operation, i.e. During the winding process, the required torque is transferred to the spool without slippage.
  • the air gap can be formed, for example, by shortening the iron path in the magnetic yoke of the electromagnet.
  • Another possibility according to the invention to provide a forced air gap is expediently that the friction or grinding surface of the electromagnet including the ends of the magnet yoke facing the armature ring is covered by an insulating washer corresponding to the width of the air gap. In this way, the braking power required for unwinding is easily provided.
  • the described invention is applicable to any area, be it that it involves winding processes in the textile industry, or that the production of electrical cables and lines requires appropriate measures.
  • a particularly preferred area of application is, for example, the stranding or roping of stranding elements by means of a known device (DE-OS 3609146) from a drivable stranding body and storage receptacles in the form of coils, in which the stranding body and the coils are combined in one unit and are available in duplicate and in Form of this unit are interchangeable, the unit with just filled coils forms the active part and the other with the coils to be filled forms the passive part.
  • a device is suitable in the same way for stranding individual stranding elements as well as for stranding layers onto elongated material.
  • the respective units are compact systems, which can be loaded for a short time after the storage stocks are idle.
  • the loading itself can be carried out on an order basis, that is, according to a predetermined program, the stock receptacles are filled with stranding elements of different or the same length and / or cross sections and / or material.
  • the bobbins depending on the operating mode (active-passive), either run without brake force control or slip-free connected to the drive shaft.
  • FIG. 1 illustrates the invention itself on a larger scale than FIG. 2
  • FIG. 2 shows an advantageous application of the invention.
  • the coil 2 for example filled with a wire supply 1, has a recess 4 on the end face of the coil core 3, in which the armature ring 5 is guided so as to be movable in the axial direction.
  • the anchor ring 5 is held by a screw 6 with which the retaining ring 7 is fastened to the base of the recess.
  • the non-positive connection between the retaining ring 7 and the anchor ring 5 is achieved by leaf springs 8 mutually screwed to the adjacent parts.
  • the armature ring 5 Opposite the armature ring 5 is the electromagnet 9, also arranged in a ring, it consists of the excitation winding 10 and the magnetic yoke 11 and a friction or grinding surface 12.
  • the coil 2 On the shaft 13 of a winding or stranding machine, the coil 2 is free by means of ball bearings (not shown) rotatably mounted, so that the armature ring 5, attached to the coil core 3, rotates with.
  • the electromagnet 9 is rigidly connected to the shaft 13.
  • the armature ring 5 When the excitation winding 10 is loaded with the full excitation voltage, e.g. of 24V, the armature ring 5 is briefly tightened, the previously possibly free-running coil is braked. The resulting frictional connection between the electromagnet 9 rigidly connected to the shaft 13 and the armature ring 5 allows the coil 2 to be filled when the shaft 13 is driven by winding up wires or strips.
  • the full excitation voltage e.g. of 24V
  • the electromagnet 9 is de-energized to de-energize the armature ring, the material can be pulled off when the spool 2 is freely rotating.
  • the air gap 14 brings about a uniform braking of the coil 2 during unwinding of the material, for example with a reduced excitation voltage of 0-6V, without influencing the positive connection required for driving the shaft 13 for the purpose of winding.
  • the magnetic yoke 11 is set back by the width of the gap 14; this can be achieved e.g. by turning off, i.e. mechanically removing material from the yoke faces.
  • FIG. 2 shows the use of a device according to FIG. 1 in the already mentioned rope-in or rope-in device, in which the stranding body and storage receptacles are combined into one unit and are available in duplicate.
  • a stand 16 is used for mounting, the drive takes place via the gear 17, and a possibly free-running hollow shaft 18 is used to hold the coils 2.
  • the stranding elements 19, for example individual wires, which are guided in the pipe or on the pipe, are made of Coils 2, as shown, drawn off and fed to the stranding point 21 after deflection by a guide disk 20. If the stranding elements 19 are not to be stranded together, but rather are to be stranded onto a cable core, the cable core itself is guided through the hollow shaft 18 to the stranding point 21.
  • two devices 22 and 23 consisting of stranding bodies and coils are arranged side by side in one plane.
  • the structure of these units is identical; the two units 22 and 23 can be pivoted relative to one another via a suitable changing device 24.
  • This pivoting is expediently revolver-like, this means in the specific case that after emptying the coils 2, the unit 22 is pivoted out of the operating position and at the same time the unit 23 is returned to the operating position.
  • the charging station 24 is used to fill the unit 22, which is swiveled out with empty coils, in which, for example, stranding elements, for example wires, of different dimensions are present in a suitable magazine and are filled into the coils 2 according to a program by means of the schematically indicated laying device 25.
  • the loading process can also take place automatically, as can the swiveling of the units into the loading and / or operating position.
  • the coils 2 present in this cable or cable device are constructed according to FIG. 1 and equipped with the clutch / brake device according to the invention.
  • the air gap according to the invention can also be produced by an insulating washer covering the friction surface 12 and having a thickness adapted to the gap width.
