Definitions

  • the invention relates to a device for minimizing the bundle height of bundles of wire formed in a bundle forming chamber, wherein individual wire windings are conveyed on a horizontal transport path, and at the end of which are brought into an approximately vertical falling movement, and fall into a bundle forming chamber in which the Wire windings are deposited from their falling line eccentrically to the axis of symmetry of the bundle forming chamber and an angular offset between successive turns is set to be constant or variable.
  • wire rolling mills In wire rolling mills, rolled wire is placed on a conveyor belt in loops with a defined diameter with the aid of a winding layer, transported further and thereby cooled. At the end of the transport route, the wire windings are collected in a bundle forming chamber and laid in bundles. If the turns fall into the bundle forming chamber without manipulation devices such as grippers, hooks, rotating devices for defining the depositing position of the turns, e.g. rotating inner mandrel, then bundles result with a height determined by randomness of the deposit, the turns essentially being approximately centered around one Inside the mandrel of the bundle chamber.
  • manipulation devices such as grippers, hooks, rotating devices for defining the depositing position of the turns, e.g. rotating inner mandrel
  • the bundle height of turns in a bundle formation chamber can be significantly influenced by orderly depositing the turns. This results in a more uniform bundle structure than with freely falling turns. In addition, orderly storage leads to better unwindability and higher stability of the wire bundles.
  • Document EP 0 768 126 A1 discloses a method for minimizing the height of wire coils resulting from the sequential collection of a large number of wire windings in a coil formation chamber.
  • the aim of the known method is to show a possibility by means of which the height of wire coils can be minimized and at the same time the tightest possible packing of the wire windings contained therein can be brought about.
  • the wire windings are subjected to an additional horizontal spinning movement during their essentially vertical falling movement.
  • the spin movements acting on the individual wire windings have the consequence that the wire windings are displaced outwards to a larger diameter than that determined by the inlet housing and are consequently displaced either against the inner circumference of the bundle forming chamber or against one another. This results in the bundle chamber in a simple manner densely packed, reduced in height and stabilized winding packages or wire bundles.
  • a wire winding transport device is followed by an underlying coil formation chamber via a vertically aligned inlet housing for successive wire turns. It is essentially constructed in such a way that there is an additional wire guide housing in a height area between the inlet housing and the bundle forming chamber, and this on a vertical longitudinal axis horizontal path curve surrounding the inlet housing and the bundle forming chamber is movably drivable.

Means for minimizing the bundle height of wire bundles produced by collecting a large number of wire windings in the bundle forming chamber are not provided.

  • EP 0 442 835 B1 discloses a method for forming bundles of metal wire, according to which preformed wire turns are dropped into a shaft which has a substantially cylindrical wall with a vertical axis, in which the turns overlap to form a bundle.
  • the method is applied to a metal wire which can be attracted by a magnet, and during the free fall of the windings, an attractive force is exerted thereon in the direction of the wall of the shaft.
  • This force is generated by a rotating magnetic field that penetrates the interior of the shaft to a depth that is at least equal to the difference between the inner diameter of the shaft and the diameter of the windings.
  • the direction of this force is determined by rotary movements around the axis of the shaft.
  • the magnetic field is generated by electromagnets, which are distributed at equal intervals around the circumference of the shaft and are fed cyclically with direct current.
