Definitions

  • the present invention relates to a method for winding closed cores for electrical coils and a device for carrying out this method.
  • a method according to the preamble of claim 1 is known from US-A-2 959 366, according to which for the winding of closed cores for electrical coils, in which a winding wire, the length of which is selected according to the winding to be produced, with its beginning with a magnetizable needle is fixedly connected and fixed at its end, after which the core is rotated by means of a core rotating device and the needle is guided under the action of a magnetic field along a closed orbit which is shortened with increasing winding duration and which is guided in a region of its length through the core opening.
  • the non-continuous transport of the needle takes place in this method by means of a permanent magnet, which is on a fixed, closed and upright orbit of constant length by mechanical means, e.g. of a conveyor belt including conveyor chain.
  • a peculiarity of this process is that after each passage through the core opening, the needle "detaches” from the magnet and, due to the upright orbit, falls onto the lower half of the path and is only then picked up by the magnet again when it passes through a certain further, lower path section Has. This period of time between the “detachment” and the “resumption” of the needle is considerable and increases with the number of turns.
  • the device according to US Pat. No. 2,259,366 intended for carrying out this method also has numerous elements which are not suitable for automation.
  • this device has z. B. two upright, parallel and spaced from each other, as well as screwed plates, between which the upright orbit, consisting essentially of a closed belt with arranged on the outside of the conveyor chain for the permanent magnet, is aligned.
  • the upright orbit consisting essentially of a closed belt with arranged on the outside of the conveyor chain for the permanent magnet.
  • one of the two plates must always be unscrewed or screwed on, which is not possible without considerable effort.
  • the guiding of the winding wire which takes place on the inside of the band and to avoid the undesirable formation of loops under at least a slight pull, also causes, due to the upright orbit, difficulties which are solved in this known device by means of a complex device, namely by spring elements.
  • the present invention has for its object to provide a method that at least for the semi-automatic winding of small toroidal coils, e.g. in the order of magnitude ⁇ 16 mm toroid outer diameter is suitable.
  • a device for performing this method is to be specified, which is as prone to failure as possible with minimal effort and allows extensive automation of the winding process.
  • the method according to the preamble of claim 1 serving to solve this object provides that said winding wire length is drawn off from a supply roll, then separated from the wire remaining on the supply roll by means of a separating device, and the end of the winding wire length facing the separating point is also removed by means of a core Distance arranged wire clamping device is determined and that the magnetic field guiding the needle is generated by a closed chain of electromagnets N arranged below the horizontal plane, which are switched on and off cyclically and taking into account the shortened orbit with increasing winding duration, such that the needle is moved continuously during the entire winding process.
  • a suitable device for carrying out the method according to the invention is characterized in that it has a plate-shaped, horizontally arranged winding wire support made of electrically insulating, non-magnetic material, which is provided with an opening for receiving the core to be wound and which the core turning device and at a distance supply roll arranged for opening together with the wire pull-off device and between the opening and supply roll orderly wire clamping and separating device and that the chain of electromagnets is arranged on the surface of the winding wire support facing away from the winding wire support surface in accordance with the orbit of the needle.
  • the chain of electromagnets is expediently closed.
  • the chain of electromagnets can also run in a straight line and can be pushed in the rhythm of the needle circulating in the closed orbit from the orbit section leading through the core opening to the orbit section running parallel thereto and back again.
  • separating brush between the orbit section of the needle leading through the core opening and the orbit section that is parallel to it, the bristle ends of which rest on the contact surface of the winding wire support with slight pressure, such that the winding wire is guided under tension.
  • the separating brush preferably has thin plastic bristles.
  • the winding wire support 1 shows a horizontally arranged, rectangular and plate-shaped winding wire support 1 made of electrically insulating, non-magnetic material, in particular plastic.
  • the winding wire support 1 has a rectangular opening 3, which serves to receive an annular core 2 shown in FIG.
  • this toroidal core is rotated in the direction of arrow A by a partially indicated core rotating device consisting of 3 rollers, two of which, namely the rollers 20, 21, are shown.
  • a supply roll 4 wound with wire 13 is arranged at a distance from the winding wire support 1.
  • a wire cutting device 6 which can be pivoted in the double arrow direction B and a wire clamping device 5 which can be displaced in the double arrow direction C are connected between this supply roll and the opening 3.
  • a closed chain of electromagnets M is arranged along the dashed line and indicated by arrows D, which chain is continued in the desired manner by a conventional electrical circuit, not shown in the drawing can be switched on and off.
  • a base plate made of insulating material, in particular plastic are indicated.
  • a separating brush 11 is arranged, the preferably thin plastic bristles 16 of which rest on the winding wire support surface 1 under slight pressure.
  • the electromagnets M are - as already mentioned - switched on and off, viewed in the direction of the orbit marked by arrow D, the steel needle being pulled from electromagnet to electromagnet.
  • the steel needle 7 jumps to the side of the opposite track and is taken to the front reversal point adjacent to the ferrite ring core 2. There the steel needle jumps onto the path section leading through the ring core opening.
  • the control of the electromagnet M takes place, for. B. via «ring counter», step switches and the like ..
  • To align the steel needle 7 in the direction of the orbit it is advisable to generate weaker «conductive fields» adjacent to the current-carrying electromagnet M, by a correspondingly lower current flow through these neighboring electromagnets. If the magnetic path is shortened with increasing winding times by control devices, the total winding time can be shortened considerably.
  • additional magnets (not shown in the drawing) can be arranged over the contact surface 1 of the winding wire 13.
  • the constant alignment of the steel needle 7 in the winding direction is, for example, by appropriate formation of the magnetic field, i.e. e.g. possible thanks to comb-like poles of the electromagnets.
