Definitions

  • the invention relates to a device and a method for the magazine-free winding of toroidal cores that can be guided in a toroidal core holder with a wire comprising several wire sections.
  • a toroidal core coil winding device with a toroidal core holder and an annular magazine guided through the toroidal core opening with elements used for wire guidance and wire magazine storage is, for example, from DE 101 53 896 A1 known.
  • the disadvantage of this known device is that the ring-shaped magazine has to be guided through the ring core for magazine storage and winding and thus ring cores with a small diameter or tube cores through which the magazine cannot be guided due to the spatial requirements of the magazine cannot or cannot be completely wound when winding with thicker wires.
  • US4 884 758 A discloses a device with a toroidal core holder for winding toroidal cores that can be guided in the toroidal core holder with a wire comprising several wire sections.
  • the present invention is therefore based on the object of creating a device for the magazine-free winding of toroidal cores and a corresponding winding method, which enable automated and magazine-free winding of toroidal cores with, in particular, a comparatively small toroidal core diameter and of tube cores with a very small diameter.
  • the device should be simple and robust and can be produced inexpensively. Magazineless winding is understood to mean that an annular magazine does not have to be guided through the toroidal core opening, as in the prior art.
  • the invention provides a device with a toroidal core holder for winding toroidal cores that can be guided in the toroidal core holder with a wire comprising several wire sections, wherein the toroidal core holder driving a toroidal core to be wound and the wire are preferably aligned perpendicular to one another.
  • the device further comprises a substantially circular needle ring arranged in a winding plane that is substantially parallel to the wire, which is rotatably mounted and can be positioned relative to the toroidal core holder such that the needle ring winds a wire section located in the winding plane through and around a toroidal core that is guided in the toroidal core holder during operation.
  • the needle ring further comprises a deflection roller that is rotatably mounted in a first recess in the winding plane on the needle ring and is designed to wind the wire section located in the winding plane through and around the toroidal core during operation; and a chicane which is arranged in a second recess in the winding plane adjacent to the first recess on the needle ring and is designed to guide the wire to be wound during operation over a guide groove between the winding plane and a magazine plane arranged essentially parallel to the winding plane.
  • the device also comprises a plurality of magazine elements arranged in the magazine plane, which are mounted in a stationary and rotatable manner and are designed to magazine wire sections located in the magazine plane.
  • a method for winding a toroidal core that can be guided in a toroidal core holder with a wire comprising several wire sections without a magazine.
  • the method includes the rotation of a needle ring comprising a baffle and a deflection roller through the ring core and also the following steps: guiding a wire section located in a magazine level of the wire magazined on several magazine elements from magazine elements arranged in the magazine level via a guide groove of the baffle onto the deflection roller, which is arranged in a winding plane arranged essentially parallel to the magazining plane; Guiding the wire section located in the winding plane around the deflection roller towards the toroidal core; Winding the toroidal core with the wire section located in the winding plane; and return an unwound wire section located in the winding plane via the deflection roller through the guide groove onto the several magazining elements in the magazining plane.
  • the magazine is thus stored via the magazine elements arranged in the magazine level, in that the wire sections located in the magazine level are stored on the magazine elements. Since a predetermined length of wire from a wire supply is simultaneously wound through and around the toroidal core and stored on the magazine elements, the winding cycle time is reduced comparatively. Since the use of the magazine elements, which are not guided through the toroidal core during storage and winding, and the associated omission of a conventional magazine for wire storage, only a wire section located in the winding level is guided through the toroidal core at the end of the winding, so that even toroidal cores with a very small residual hole diameter (inner diameter of the wound toroidal core with wound wire layers at the end of the winding) can be wound. Furthermore, toroidal cores with small inner diameters or with thicker wires can be wound than is possible with conventional toroidal core winding machines.
  • the device according to the invention is of simple construction since the annular magazine can be dispensed with. Due to the relatively simple structure, the device is also robust and inexpensive to manufacture.
  • the method according to the invention thus allows automated and magazine-free winding of toroidal cores with a small inner diameter or tube cores or other core geometries that cannot be wound with conventional toroidal core (coil) winding devices with a magazine.
  • the invention is simple in design, since it does not require transport rollers, a wire ejector and a wire tightener. can be dispensed with. Due to the relatively simple structure, the device is also robust and inexpensive to manufacture.
  • the method according to the invention thus allows automated and magazine-free winding of toroidal cores with a small inner diameter or tubular cores or other core geometries that cannot be wound with conventional toroidal core winding devices with several wire sections stored in the winding plane.
  • an interruption interrupts the substantially circular shape of the needle ring in an area so that the ring core can be positioned in the circumference of the needle ring or the needle ring in a position intended for winding the ring core, in which the needle ring is arranged so that it can be rotated by the toroidal core.
  • the needle ring can leave this position again and the toroidal core can be removed from the toroidal core holder.
  • the needle ring comprises a toothed ring which is arranged in a drive plane which is arranged essentially parallel to the winding plane and is designed to drive the needle ring in rotation.
  • the ring gear has teeth through which it is rotationally driven by an external drive unit. The rotational movement of the gear ring is transferred to the needle ring so that the toroidal core can be wound. This increases process control and simplifies the handling of the device.
  • the needle ring is designed to simultaneously wind the wire section located in the winding plane during operation through and around the toroidal core guided in the toroidal core holder and to store the wire section located in the magazine plane on the multiple magazine elements.
  • the wire is initially introduced into the device from a wire supply until a predetermined length of the wire is fed.
  • the predetermined length of the wire from the wire supply is simultaneously wound through and around the toroidal core and stored on the magazine elements located in the magazine plane.
  • the wire is separated from the wire supply so that no further wire is fed from the wire supply and the wire sections located in the winding plane are wound through and around the toroidal core. This minimizes the amount of leftover wire that cannot be wound onto the toroidal core and enables easy automation of the process.
  • the deflection roller is designed to wind the wire section located in the winding plane centrally through and around the toroidal core. This allows the quality of the wound toroidal cores to be increased by winding the wire turns perpendicularly onto toroidal cores with a substantially circular geometry during the winding process. In addition, this aspect offers more space within the toroidal core during winding. This enables a lateral relative movement between the toroidal core and the needle ring, for example to bring toroidal cores with a non-circular geometry into a central position relative to the needle ring.
  • the device further comprises at least one wire brake, wherein the at least one wire brake is designed to brake the wire section located in the magazine level at intervals by pressing it against at least one of the plurality of magazine elements and to tighten the wire during operation.
  • the at least one wire brake is designed to brake the wire section located in the magazine level at intervals by pressing it against at least one of the plurality of magazine elements and to tighten the wire during operation.
  • the plurality of magazine elements are designed as rollers which are rotationally driven at intervals in an interaction with the at least one wire brake.
  • the magazine elements are mounted on a side facing away from the needle ring and closed off by surrounding areas.
  • means are provided on a side of the magazine elements facing the needle ring to prevent the elements located in the magazine level from accidentally falling down To avoid wire sections from the magazine elements during winding. These means are preferably a circumferential bevel.
  • the wire section located in the magazine level In an area of the orbit of the needle ring, which the deflection roller with the wire section located in the winding plane has passed within one revolution, the wire section located in the magazine level is driven via the rollers in the direction of rotation of the needle ring and is not braked via the at least one wire brake. In an area of the orbit of the needle ring that the deflection roller with the wire section located in the winding plane has not yet passed within one rotation, the wire section located in the magazine level is not driven via the rollers in the direction of rotation of the needle ring and is braked via the at least one wire brake. This allows the load on the wire to be kept constant and the risk of breakage is reduced. This also prevents the wire from moving loosely in the system during winding, which can increase the quality of the winding.
  • the device 1000 for magazine-free winding of toroidal cores 2000 preferably has a toroidal core holder (not shown) in which the toroidal core 2000 to be wound is held and rotated during winding.
  • the toroidal core holder is formed by three pressure rollers (not shown), which are preferably each arranged at an angle of 120° to one another around the toroidal core 2000 and press against the toroidal core 2000 from the outside and thus hold it in the desired position. At least one of the pressure rollers simultaneously drives the toroidal core 2000 and thus sets it in the desired rotation in order to wind the turns around the toroidal core 2000 at a desired distance.
  • the device 1000 for magazine-free winding of toroidal cores 2000 has several magazine elements 1210, 1220, 1230, 1240 arranged in the magazine level 4200, which are mounted in a stationary and rotatable manner and are set up to magazine wire sections 3200 located in the magazine level 4200.

  • the toroidal core 2000 is wound by the needle ring 1100 with the deflection roller 1111 with the wire section 3100 located in the winding plane 4100.

The wire section 3100 located in the winding level 4100 is then guided around the deflection roller 1111 to the toroidal core 2000 and wound around the toroidal core 2000.
