Definitions

  • the invention relates to a wound wire coil, such as in particular a wire coil for receiving metal wire for further processing into jewelry, according to the preamble of claim 1 and a method for producing the wire coil and an apparatus for performing the method.
  • the wire spool has a take-up spool, which is essentially formed from a spool core with a cylindrical surface and lateral disks perpendicular thereto.
  • the take-up spool has a wire winding arranged on the spool of a wire, which forms a plurality of radially superimposed layers, each of which defines an average laying width corresponding to a respective pitch of adjacent wire sections of a layer.
  • Further deflecting points are formed on the side windows, at each of which a laying direction of the wire changes and thereby each form a transition between two superimposed layers. The deflection points can therefore also be referred to as laying reversal points.
  • a disadvantage of the wire coils obtained in this case is that they tend during unwinding to a sinking of the wire in the remaining wire wrapping. This sinking can lead to a jamming of the unwound wire within the remaining wire wrap, which can lead to disruption, production interruptions or errors in the products to be produced, for example, in the continuous production of jewelry chains.
  • DE 289216 shows a coil for electrical purposes, which consists of wire layers and intermediate thread layers.
  • a thread guide for the production of the thread layers is controlled so that it changes the direction several times when passing through a coil length.
  • the wire is laid in uniformly closed turns on the sleeve.
  • US 3,601,549 shows a wound cable spool with a take-up spool having side sheaths which are in a mutually oppositely directed inclination angle of 30 °.
  • all windings of the respective cable are always arranged on a gap to the windings of the respective underlying layer from a second position.
  • the layers have mutually offset deflection regions which extend over an angular section of 60 ° and in which the windings have a different laying angle relative to the remaining angular section of 300 ° of the respective layer.
  • US 5,209,414 describes a system for winding a wire coil.
  • means are provided which ensures an exact juxtaposition of adjacent wire windings.
  • a side window may further be provided, which is adjustable relative to a second side window.
  • EP 0 334 211 A1 shows a method of manufacturing a bobbinless container in which a plurality of layers of a strand-like material are wound in an inclined orientation on a frusto-conical receiving coil.
  • DE 200 08 405 U1 describes a system for laying materials such as threads, ropes or wires on a bobbin.
  • a laser distance sensor is provided by means of which a uniform winding can be produced across all layers.
  • EP 1 013 618 A1 shows a method for winding an optical fiber element with different properties in sections. In order to display each case the change from one section to the next section with other properties, the sections are each wound differently.
  • the object of the invention is to avoid the disadvantages mentioned in a generic wound wire coil and to ensure a trouble-free unwinding of the recorded wire winding.
  • a wound wire coil having the features of claim 1.
  • all deflection points are offset relative to the respective adjacent deflection points in the circumferential direction.
  • an unstable arrangement of superimposed deflection points can be prevented, as they necessarily arise in the known Aufwickel compiler in which the laying speed is coupled directly and in such a way with the winding speed, that each resulting circumferential speed of the wire coil relative to the respective effective radius r a 2 ⁇ rfachen the laying speed corresponds to be able to produce a uniform winding over the entire length and the different layers of the spool core.
  • areas of indifferent storage conditions of the respective wire sections can be avoided by the wire coil according to the invention, which slip against each other during a unwinding operation and thereby promote sinking of the wire.
  • the average laying width increases from one layer to the next layer in the radial direction from the inside out. This ensures that the respectively superimposed wire sections are not laid exactly parallel and form from the inside to the outside with respect to the circumferential direction becoming larger laying angle. Due to the increasing outward laying width In this case, the resistance that the lower layers of a sinking movement of the respectively overlying layers in the radial direction can set, increases, thereby preventing in particular the sinking of the wire in each current unwinding.
  • the average laying width of the individual layers is defined by the product of a layer diameter and a wire thickness divided by a core diameter of the wire coil, wherein the layer diameter is formed in particular by an inner diameter of the respective layer.
  • the object is achieved by a method for producing a wound wire spool in one of the above embodiments, in which the wire is fed at a wire speed to the take-up spool rotating at a rotational speed.
  • the wire is guided by a laying apparatus which reciprocates parallel to a rotation axis of the take-up spool over a length of the spool core between two switching points, wherein the laying apparatus has a mean linear velocity between the switching points.
  • the rotational speed of the take-up spool decreases monotonically during the laying process.
  • an increasing average laying width of the layers is generated from the inside to the outside during the winding process at a constant wire speed. In this way, the resistance that the lower layers of a Eininkschul the respective overlying layers in the radial direction counter, increased.
  • the rotational speed of the take-up spool is abruptly reduced while the linear speed of the laying apparatus is kept substantially constant between the switching points.
  • a uniform winding of the individual layers with outwardly increasing average laying width and increasing laying angle is ensured in particular at constant wire and linear speed.
  • the rotational speed of the take-up spool whenever the laying device reaches one of the switching points, is reduced such that a circumferential speed is kept substantially constant at the respective outer layer of the wire winding and also the laying width of the product from the respective layer diameter and the wire thickness divided by a core diameter of the wire coil corresponds. This ensures that from the inside to the outside with respect to the circumferential direction increasing laying angle is formed by the sinking of the wire can be prevented in a respective current unwinding.

It is provided that the Veriegeapparat has a separate from the reel drive of the take-up reel drive. As a result, the laying apparatus can be driven independently of the coil drive in order to be able to form uniformly an increasing laying width in the individual layers from the inside to the outside.

  • the laying apparatus is driven in operation with a constant average linear speed in order to achieve a particularly uniform wire winding can.
