Definitions

  • the invention relates to a toroidal coil winding device with a toroidal holder for rotatably mounted toroidal cores, a wire feeder, a fixing element for interrupting the wire feeder and a conveying device for shaping and conveying wire loops through the toroidal core opening.
  • Such a winding device is known from US Pat. No. 3,732,901, according to which wire is withdrawn from a wire spool, transported via a wire feed to a flat conveying device, where the supplied wire is formed into a flat spiral, and each wire winding is drawn through the toroidal opening. After feeding a certain length of wire, the conveyor fixes the wire end. Through the continued rotation of the wire spiral, the wire is finally tensioned, unrolled via a wire brake and wound evenly around the ring core.
  • the wire windings must also be kept on a circular path using special guide aids.
  • the device according to US Pat. No. 3,732,901 uses a special guide channel, the width of which has to be adapted to the respective wire thicknesses.
  • the wire brake must also be readjusted for each new wire thickness and wire stiffness.
  • toroidal coil winders with a movable magazine, i.e. in particular annular, rotating magazines with an orbit through the toroid opening.
  • the wire is wound onto the magazine in a predetermined length and guided together with it through the toroidal opening.
  • winding devices with a magazine are unsuitable for winding toroidal cores with the smallest remaining holes, since the size of the remaining hole is limited by the magazine shape.
  • the present invention has for its object to constructively improve the winding device described above; in particular, this winding device is intended to enable rational, largely automatic winding of toroidal cores down to the smallest remaining holes in the order of a wire diameter, with relatively large wire lengths being able to be processed and high numbers of turns being able to be achieved.
  • the invention provides a conveyor device with at least two stationary, in the same direction driven conveyor disks, which rotate in the plane of the wire loop path and with the help of several to each other and to the conveyor disks, preferably axially parallel deflection rollers, carry a pair of transport belts in sections along the wire loop path and press them against one another, and a deflection device, by means of which the wire loop last fed in can be deflected out of the wire loop path.
  • the deflection of the clamped wire piece is advantageously carried out by the clamping device itself.
  • the conveyor belt tension and thus the winding tension can be infinitely adjusted by simply adjusting individual deflection rollers.
  • the conveying device has two large conveyor disks 5, 6 and several smaller ones Deflection rollers 10. Two pairs of conveyor belts 11, 12 and 13, 14 are moved on the conveyor disks and deflection rollers in the direction indicated by arrows.
  • the wire start is advanced by the wire feed and picked up by the pair of transport belts 11, 12, deflected and pushed through the ring core opening 3.
  • the start of the wire is then passed on by the pair of transport belts 13, 14 and released again to the pair of transport belts 11, 12.
  • the clamping device 7 stops the further wire feed.
  • the end of the wire is deflected out of the conveying plane of the wire loops under the effect of a deflecting device which is only hinted at in the drawing but is constructively familiar.
  • the wire piece is pulled out of the pair of belts 11, 12 and wound as a loop around the ring core by the winding tension of the conveyor belts 11, 12, 13, 14 which continue to run.
  • the winding tension can be varied by changing the belt tension.
  • the deflection rollers 10 of the outer transport belts 11, 13 can preferably be braced perpendicularly to their axes of rotation by spring forces.
  • the conveyor can be loaded both left and right.
  • the wire feed is pivoted and the start of the wire is first picked up by the pair of transport belts 13, 14, pushed through the ring core opening 3 and passed on to the pair of transport belts 11, 12.
  • winding with two or more wires is possible at the same time.
  • the wires are fed from separate wire feeds (not shown) and wound up in the form of loops lying next to one another in the conveyor device. The wire ends are stopped and pulled off for all wires at the same time.
  • FIG. 2 shows several snapshots of loops in chronological order from a to f.
  • the components of the conveyor device are omitted in this figure.
  • the deflected piece of wire tightens between the deflecting rod 8 and the toroidal core 1 (position a).
  • the loop forms b, c, d, e and f result at certain times.
  • FIG. 3 finally shows a sectional view through the pair of transport belts 11, 12 and the conveyor disk 5 at the time of the wire removal.
  • Five wire loops 2 are transported between the pair of conveyor belts 11, 12.
  • the wire loop shown on the left in the drawing plane is withdrawn due to the winding tension from the conveyor over the side flange 15 of the conveyor disc 5.
  • the conveyor belts 11, 12 are designed as toothed belts.
  • the conveyor disc 5 is provided with a matching ring gear 16.
  • the transport belts 11, 12 have small guide beads 17 in the edge regions, which enable easy guiding of the wire loops 2 and the transport belts 11, 12.
