Definitions

  • the invention relates to a toroidal coil winding device with a toroidal core holder, an annular magazine for wire guidance and magazation, which is guided through the toroidal core opening and possibly interrupted in a region of its length, the toroidal core and the magazine being rotatable about their rotationally symmetrical axes, which are preferably oriented perpendicular to one another and with a wire feed to the magazine.
  • Toroidal core winding devices of this type are known from US Pat. No. 4,079,895.
  • Their closed magazine has a part that can be opened for exchanging the ring cores and is closed during winding.
  • the magazine is also designed so that the winding wire is already being magazineed while the ring core is being wound.
  • the beginning of the wire is fixed to the toroid by hand and guided by hand during the entire winding process.
  • the threading of the beginning of the wire into the magazine is also very cumbersome, since the wire must be threaded between brake rollers, which bring about the required winding tension during winding.
  • a toroidal core winding device with a closed magazine which, moreover, only permits magazine storage, that is to say no magazine during winding, is known from US Pat. No. 3,982,705.
  • the wire start is also attached to the toroid by hand and guided by hand during the entire winding process.
  • DE-OS 2 307 014 describes a winding device for deflection coils with a wire storage magazine which is interrupted and rotatably supported in a region of its length and with a rotating coil winder which is likewise interrupted in an area of its length and to which the wire is supplied by the wire storage magazine.
  • a winding device too, the beginning of the wire is fixed by hand to the bobbin winder and guided by hand during the winding process.
  • DE-PS 2 820 674 finally deals with a winding device for toroidal coils with a toroidal holder, a guided through the toroidal opening, equipped for wire guidance and magazine with rotatably mounted sliding rollers, interrupted in an area of its length, annular magazine, the toroidal core and the magazine can be rotated about its preferably perpendicularly aligned rotationally symmetrical axes, and with a wire feed which is designed such that the wire start between two guide rollers is guided to a fixing element separate from the magazine for fixing the wire start, which is also arranged separately from the toroid and that releases the beginning of the wire in the course of winding.
  • the wire start is not fixed to the ring core. However, it must be ensured that the start of the wire is kept clear of the inner hole of the toroid after the release by the fixing element; otherwise the end of the wire prevents the winding magazine from being properly guided through the ring core hole.
  • the present invention has for its object to improve a toroidal winding device of the type mentioned in such a way that, if possible, a fixation of the winding wire start by hand at least, however, the manual guidance of the winding wire beginning required for individual winding devices during the entire winding process is dispensed with and the fixing and leadership can be done largely automatically.
  • the invention provides that the toroidal holder has a receiving sleeve for the toroidal cores, which can be pivoted into the orbit of the magazine and is open in its area of its lateral surface directed towards the center of the magazine in the winding position.
  • the toroid to be wound is possibly automatically placed on this receiving sleeve and then the receiving sleeve together with the toroid is pivoted into the orbit of the magazine.
  • this manual securing of the wire start is also omitted.
  • the fixing element for the wire start which is arranged away from the ring core and from the magazine, only releases the latter when the wound ring core is rotated into a position in which the released wire start is clamped between the receiving sleeve and the ring core.
  • the receiving sleeve of the toroidal core holder can - viewed in the longitudinal direction of the sleeve - be divided into two.
  • the clear cross-section of this and the one-piece receiving sleeve is of course chosen larger than the cross-section of the magazine.
  • the toroidal holder explained above contributes significantly to the automation of the toroidal winding.
  • FIG. 1 and 2 has an annular magazine 1, which is interrupted at 11 by a gap and carries on its one end face spaced-apart rollers 2.
  • Reference numeral 5 denotes a drive with a drive wheel 4 rotatably mounted on a shaft, which with further wheels 20, 22 (see FIG. 3) also rotatably mounted on shafts, against the outer surface of a ring-type holder according to FIGS. 3 to 6 Toroidal core 3 abuts.
  • the magazine 1, which is designed as a ring, in particular a ring gear, is rotated in the direction of arrow A in the illustration according to FIG. 2.
  • the transport consists of a transport wheel 15 which, when rotated in the direction of the arrow B, intermeshes with the toothed ring of the magazine via transport wheels 13, 14 which are connected in the direction of the arrow C and rotate.
  • the toroidal core 3 and the magazine 1 can be rotated about their rotationally symmetrical axes oriented perpendicular to one another.
  • the elements of the winding device are partly fixed, partly rotatable on a mounting plate 12.
  • a winding wire 8 is drawn off from a supply roll (not shown in the drawing) and conveyed in the magazine direction by means of transport rollers 6, 7 which rotate in the direction of the arrow D.
  • the magazine 1, which has, for example, a ring gear and the sliding rollers 2 are accommodated in a tubular ring-shaped covering, which is open to the center of the ring gear and is non-rotatably arranged and interrupted in an area of its length, which is not shown in the drawing and which has a wire feed-through in the area of the wire feed.
  • adjustable brushes 10 which lie on the magazine wire with more or less pressure in accordance with the desired winding tension. This makes it possible to control the winding tension, which is additionally increased by the unwinding tension from the supply roll at the start of winding and which decreases noticeably when the magazine is emptied.
  • the ring core holder has a receiving sleeve 30 arranged on a swivel arm 24 (see FIG. 4) with an annular flange 32 for supporting the toroidal core 3 and with an area 31 of its outer surface which is open towards the center of the magazine in the winding position.
  • the swivel arm 24 pivotably mounted at 25 and damped in its swiveling movement by a damping device 26, 27 is swiveled into the winding position directed towards the center of the magazine - see direction of arrow E.
  • the drive wheel 4 and the other wheels 20, 22 lie against the outer surface of the ring core 3 shown in FIG. 6 and pushed onto the receiving sleeve 30.
  • each winding is separately magazine for the double choke type. This means that programming can be carried out freely, depending on whether winding in the same direction or in the opposite direction is desired; on the other hand, the magazine only has to take up half the amount of wire and can therefore be further reduced.
