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 has a spool core with a cylindrical surface and side windows perpendicular thereto, and a wire winding of a wire arranged on the spool core, which forms a plurality of layers arranged one above the other in the radial direction.
  • deflection points are formed on the side windows, on 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.
  • DE 10 2006 018 428 A1 shows a method and apparatus for winding a wire spool, in which the formation of valleys and mountains of the winding material is prevented on a bobbin to optimally use a winding volume of the wire coil can.
  • EP 0334 211 A1 describes a method for producing a bobbinless container, in which the material to be wound is wound up in inwardly increasing widths from the outside to a truncated cone-shaped take-up spool. To produce the different positional widths means are provided which allow a change of direction between the outer deflection points of the winding.
  • DE 4009370 A1 shows a method for producing a cross-wound bobbin on which a spun yarn is placed crosswise.
  • EP 0762445 A2 and DE 289216 A each describe a winding method for producing an electromagnetic coil.
  • 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.
  • 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.
  • the wire has overlapping sections between the two deflection points of one of the layers, which form additional transitions between superimposed layers. In this way, over the cross section of the wound wire regions with indifferent storage conditions of each unwinding during the unwinding wire sections can be avoided. This reduces the risk that the wire section to be unwound and the wire sections arranged below it will slip against one another during a unwinding operation and as a result the wire section to be unwound sinks and jams.
  • the overlapping portions are formed in each layer of the wound wire coil, whereby a fully increased resistance to sinking of the unwound wire section can be ensured.
  • At least two overlapping sections are formed in one of the layers, which extend in the axial direction of the wire coil in each case between a first transition from the respective layer to another layer and a second transition back to the starting layer over sublayers of different sizes. Due to the overlapping portions of different sizes, the resistance that the lower layers of a sinking movement of the respective overlying layers in the radial direction set, increases, and thus in particular the sinking of the wire in each current Abwickelungs Geb be prevented.
  • the overlapping sections extend over an angle section of at least 360 ° in each case.
  • the overlapping sections have a relatively high positional stability during their production.
  • the object is achieved by a method for producing a wound wire spool in one of the above-mentioned embodiments, in which the wire is fed to the rotating take-up spool and guided thereby by a laying apparatus which is parallel to a rotation axis of the take-up spool over a length of the spool core between two switching points reciprocated, wherein a part of the laying apparatus is moved along a linear main movement direction of each one of the switching points to the other switching point, said main linear motion is superimposed with a multiple alternating movement, so that over a laying length of each prepared layer a plurality of overlapping portions are formed.
  • a plurality of overlapping sections are formed at each point along the laying length of a respective outer layer below the same, through which the resistance that the lower layers of a sinking movement of the respectively overlying layers in the radial direction oppose, can be increased.
  • the overlapping sections in this case extend over part-length lengths of different lengths.
  • the object is achieved by a device for carrying out the method in one of the above embodiments, in which a wire dispensing device is provided, from which the wire can be fed via the laying apparatus of a coil receiving, to which the take-up spool is driven by a coil drive, wherein the laying apparatus has a separate from the reel drive of the take-up reel laying drive and means for changing direction also between the switching points.
  • the laying apparatus can be driven independently of the reel drive and in particular independently of the rotational speed and position of the reel seat form the overlapping sections.
  • the means for changing direction between the switching points comprise a runner of the laying apparatus connected to a control device and linearly movable along a stationary element.
  • the linear direction of movement of the rotor can be changed or changed as a function of a control signal of the control device.
  • control device prefferably has a programmable random number generator for generating the control signal.
  • the frequency and respective extension of the overlapping portions are randomly distributed across the plies of the wire coil to be produced.
  • Fig. 1 shows a wound wire spool 2 with a take-up spool 4, which has a spool core 6 with a cylindrical surface 8.
  • the cylindrical surface 8 is bounded at both ends by a respective perpendicular to the side window 10a, 10b.
  • a wire winding 12 is wound on the spool core 6, which is formed from a wire 14, such as in particular a usual for the production of jewelry metal wire.
  • the wire winding 12 comprises in the radial direction R of the wire coil 2 a plurality of superimposed layers L1, L2, L3, L4 of the wire 14.
  • L1, L2, L3, L4 of the wire 14 As an alternative to the wire 14 shown here with a round cross-section is also the use of a wire 14 with oval, half-round or flat Cross section possible.
  • Fig. 1 shows the wire winding 12 in this case at the beginning of a winding process in which the wire cross sections of the wound wire 14 in the illustrated sectional plane are arranged according to a dot-dash installation path V between a starting point SP on one of the side windows 10a and a first deflection point U1 on the other side window 10b, wherein the deflection point U1 denotes a transition at the end of the first layer L1 to the second layer L2.
  • the deflection point U1 denotes a transition at the end of the first layer L1 to the second layer L2.
  • overlapping portions 16 are formed when laying the wire 14 according to installation path V, which additionally form transitions Z1, Z2, Z3, Z4 between each adjacent layers L1, L2, L3, L4 between the deflection points U1, U2, U3 ,
  • the overlapping sections 16 extend in the axial direction in each case over a Sectionverlegerat tl, each of which is a fraction of the total laying length I, which is limited by the distance between the two side windows 10a, 10b.
  • the overlapping portions 16 with respect to a tangential direction of the spool core 6 for reasons of stability at least an angular portion of 360 °, and they are preferably, as shown, each wound several times around the spool core 6.
  • a device 20 is shown, by means of which the wound wire spool 2 can be produced.
  • This device 20 has a wire dispenser 22 in the form of an annealing device, from which the wire 14 is output at a wire speed vG.
  • the device 20 has a laying device 24, via which the wire 14 can be fed in a predetermined manner to the take-up spool 4 arranged in a spool receptacle 26.
  • the laying device 24 has a laying apparatus 28 which can be displaced along a laying axis AV parallel to a rotation axis AD of the pickup coil 4 clamped in the coil receptacle 26 by means of a laying drive 30.
  • the laying apparatus 24 can in this case be moved back and forth along a linear main movement direction HR between two switching points 32a, 32b.
  • the laying apparatus 28 in this case has a rotor 34 which, in addition to the main movement along the respective main movement direction HR, can be alternately moved back and forth with a superposition movement along a partial movement direction TR in order to move the overlapping sections 16 over the produce respective partial laying length tl.
  • the rotor 34 is linearly displaceable along a guide element 36 for this purpose.
  • the take-up reel 4 is also driven by a reel drive 38 about the axis of rotation AD, which is formed separately from the laying drive 30.
  • the wire dispenser 22, the laying drive 30 and the spool drive 38 are provided with a Control device 40 connected.
