Definitions

  • the invention relates to a toroidal winding device with a toroidal core holder and a magazine-free wire guide and a corresponding method for this purpose.
  • a toroidal coil winding device with a toroidal core holder and guided through the toroidal core annular magazine with serving for wire guide and Drahtmagazin ist elements is for example from DE 101 53 896 A1 known.
  • the disadvantage of this known device is that the annular magazine for magazine storage and winding must be performed by the toroidal core and thus ring cores with a small diameter or tubular cores, through which the magazine can not be performed because of the spatial requirements of the magazine, not be wound can.
  • the present invention is therefore an object of the invention to provide a winding device and a corresponding winding method, which allow a direct winding of toroidal cores with a very small inner ring diameter and tube cores.
  • the device should be simple and robust and inexpensive to produce.
  • the invention provides a device for magazineless winding of toroidal cores with a toroidal support and arranged in a wire guide plane for wire guide and Drahtmagazin ist serving elements, the one to be wound toroidal core driving ring core and serving for wire guide and Drahtmagazin ist elements preferably perpendicular aligned with each other.
  • the wire guide and wire storage elements further comprise a first transport roller and a second transport roller arranged relative to the toroidal support such that a wire to be magazined and wound in the wire guide plane on the transport rollers is passable through the toroidal core between the first and second transport rollers; a wire ejector disposed adjacent to the second transport roller and a wire tensioner.
  • the wire ejector is set up in operation to move a loop of the wire to be wound after passing through the ring core from the wire guide plane laterally adjacent to the second transport roller. This ensures that the wire loop drops from the second transport roller or is passed past this and runs in the sequence in the wire tensioner.
  • the wire tensioner is set up to tighten the wire loop first and then release it for further winding.
  • a method for magazineless winding of toroidal cores with a wire by means of a winding device comprises the following steps: guiding a preferably consisting of a one-piece wire rotating wire belt on the first transport roller through the ring core in the substantially perpendicular to the wire rotating ring core, continue on the second transport roller and again to the first transport roller in the wire guide plane, forming a loop of the wire from the wire band next to the first transport roller, passing through the toroidal core and displacing the wire loop from the wire guide plane next to the second transport roller through the wire ejector, tightening the wire loop in the wire tensioner and releasing the wire loop through the wire tensioner.
  • the storage of the winding wire is thus carried out according to the invention without conventional magazine by the wire is maga conclude directly on the transport rollers. This can be dispensed with a closed magazine for guiding and storing the winding wire. Since thus only the wire to be wound and no magazine o.ä. must be guided through the toroidal core and ring cores with a small inner diameter or tubular cores can be wound.
  • the inventive method thus allows an automatic winding of ring cores with a small inner diameter or pipe cores or other core geometries that can not be wound with conventional winding devices with magazine.
  • the elements used for wire guidance and wire magazineing furthermore have at least one auxiliary roller.
  • At least one of the transport or auxiliary rollers is designed as a drive or pull roller.
  • the drive or traction roller drives the wire on the wire as a so-called wire belt, so that it rotates over the first transor roller through the wrestlers and further on the second transport roller.
  • the drive further ensures the tightening of the wire in the wire tensioner, by also rotating the wire loop and with each rotation of the wire tightened and then released again.
  • Further auxiliary rollers lead the wire on the way from the second to the first transport roller in a preferred manner on a semicircular path, so that a sufficiently large amount of wire can be magazineed on and a particularly good loop formation is made possible.
  • the transport or auxiliary roles are set up so that during operation when Magazining the wire forms a closed wire belt, which can be passed through the toroidal core.
  • Closed wire belt means that when a wire to be wound wire is preferably wound in several juxtaposed wire turns on the rollers.
  • the wire belt is, according to one aspect of a supply of wire, magazined onto the rollers of the device by, for example, winding a wire of predetermined length onto the rollers.
  • one end of the wire which is stored in the form of a wire belt and guided through the toroidal core, is then fixed at the beginning of the actual winding onto the toroidal core so that the wire can be wound around the toroidal core.
  • the wire tensioner includes a gap forming biased wedge.
  • the wire tensioner is set up and arranged so that in operation, the wire loop runs after passing through the toroidal core in the gap and It is initially performed in the gap and in the wire direction passes through the gap.
  • the wedge-shaped gap is so small in the prestressed state at its narrowest point that slippage of the wire loop in the radial direction is initially prevented by being smaller than the wire diameter in this state, the gap at the narrowest point.
  • the wire loop continues to run in the wire direction through the gap and is tightened. In this case, the wire loop continues to contract around the ring core, so that a further turn is created.
  • the radial tensile force of the wire in the direction of the wedge tip of the gap becomes increasingly greater.
  • the wire loop falls or slips at sufficiently high tensile force in the radial direction through the gap bottom and thus leaves the wire tensioner or is released from this.
  • the wire loop is pulled further by the continuous Anrieb the rotating wire belt.
  • the wire ejector is configured as a rotating means and arranged such that, in use, the at least one rotating means engages a wire loop from the wire band, driving the wire crazy and thereby safely and simply ejecting the wire loop.
  • the wire loop falls when ejected from the second transport roller. In addition, re-threading on the second transport wheel is prevented.
  • the wire loop then continues to run in the wire tensioner.
  • the rotating means according to one embodiment is a wheel with at least one driver or a star or gear or a rotating toothed belt or a rotating chain with at least one outer running cam or hook.
  • the wire ejector is advantageously synchronized with the device so that one of the preferably several rotating drivers, teeth, cams or hooks detects each one of the wire belt revolutions - and the next on the wire belt starting from the wire loop - and so crazy that this wire loop falls from the second transport roller.
  • the device further comprises at least one wire guide means, which is set up in such a way that, during operation, it passes the wire released by the wire tensioner past the upper transport roller, so that the wire loop forms again and the wire does not thread back onto the first transport wheel.
  • the device further comprises at least one wire guide plate parallel to the wire guide plane, which at least partially covers the upper transport roller and thus reliably prevents the wire loop threading back onto the first transport wheel and thus reliably forming the wire loop again.
  • the toroidal winding apparatus 100 has a toroidal support (not shown) in which the toroidal core 110 to be wound is held and rotated during winding.
  • the toroidal support is formed according to an embodiment by three pinch rollers, which are each arranged at a distance of 120 ° to each other around the ring core and press from the outside against the toroidal core and thus keep it in the desired position. At least one of the pinch rollers simultaneously drives the toroidal core and thus puts it in the desired rotation to apply the turns of the winding at the desired distance on the toroidal core.
  • the device has arranged in the wire guide plane serving for wire guide and Drahtmagazin ist elements, in particular on the first and second transport roller 120, 130 and, if available, further auxiliary rollers 140, 150, 160, 170 together generally referred to as wire guide rollers, the are each arranged on mutually parallel axes of rotation.

  • the axis of rotation of the ring core is preferably substantially in the wire guide plane, so that the axes of rotation of the ring core and the wire guide rollers are preferably aligned perpendicular to each other.
  • the first transport roller is designed as an upper transport roller 120 and arranged above the toroidal support 110.
  • the second transport roller is correspondingly arranged as a lower transport roller 130 so that the wire 200 guided from the upper to the lower transport roller passes through the toroidal core to be wound in the toroidal support.
  • a rope is guided over the wire guide rollers and through the toroidal core, as then the wire is to be magazined as a wire belt in the device including toroidal core.
  • the rope is then knotted as a closed loop, for example, or otherwise closed and linked to the (winding) wire beginning.
  • the winding wire beginning can also be guided directly over the wire guide rollers and through the toroidal core and then closed when the starting point is reached.
  • the winding wire is, for example, withdrawn from a supply roll (not shown) and then stored in the device on the wire guide rollers by driving at least one of the wire guide rollers - the at least one drive or pull roller.
  • the winding wire is ready to be magazined when the sufficiently long piece of wire has been wound onto the wire guide rollers.
  • the wire forms a multi-turn wire band 210, as in, for example, in FIG. 2 is shown.

  • the one free end of the wire is attached to a suitable fixture of the device, such as the toroidal support, or can also be held by operators during winding.
  • the wire belt is then driven by the drive or pull roller 160 and set in rotation so that the wire belt on the first transport roller through the toroidal core to the second transport roller and then further on, if necessary, the auxiliary rollers back to the first Transport roller is running, as for example in Fig. 3 is shown.
  • One turn of the wire belt is then first thrown from the second transport roller and forms a wire loop for winding the toroidal core.
  • the wire ejector 300 is expediently below the toroidal core 110 and in the vicinity of the lower transport roller 130, as in the Fig. 3-5 shown, and arranged in operation so that the portion 230 of the loop of the winding wire to be wound after passing through the ring core from the wire guide plane laterally so crazy that the wire loop from the second wire roll falls or not on the second transport roller but in the wire tightening runs.
  • the wire ejector is designed according to an embodiment as a star wheel or wheel with at least one driver 310, wherein the wheel rotates so that a Tooth of the star wheel or a driver detects the portion 230 of the loop to be looping of the wire to be wound and laterally out of the wire guide plane.
  • Alternative wire ejectors include rotating belts or chains with at least one outboard cam, cams, hooks or the like.

  • the wire tightener 400 first tightens the wire loop and then releases it.
  • the wire tensioner comprises a gap-forming prestressed wedge 410. This wedge forms a gap 440 into which the wire section 240 runs with an opposing surface 430 of the device arranged substantially parallel to the wire guidance plane.
  • the wedge or opposing surface is biased, for example by a spring 420, and supported so that the wedge 420 and the opposing surface 430 are urged against each other by spring force and form a quasi-closed gap 440, respectively the narrower side of the gap is smaller than the wire diameter, so that the wire in the wire direction passes through the gap, but does not slip in the radial direction through the gap.
  • the wedge and the opposing surface move so far apart in that the gap widens or opens and allows the wire to slide in the radial direction through the gap bottom or the narrow side of the gap.
