Definitions

  • RFID radio-based transponder technology
  • the invention relates to a fastening means for transponders for the identification of metallic or metal-containing objects via radio-based transponder technology (RFID), wherein the transponder is temporarily attached to the metallic objects by means of magnetic force.
  • RFID radio-based transponder technology
  • JP 2004-217221 A describes a method for attaching a transponder to a metal container, wherein an installation gap for the transponder is provided in the container. The transponder is inserted ⁇ in this gap.
  • Transponders and containers require a special production. Only a low to medium range of a few centimeters is achieved.
  • EP 1 447 769 A1 relates to the arrangement of an active transponder on metallically conductive containers, wherein the transponder must be placed as close as possible to the surface or even integrated in the surface at a certain point of the container, so that the transponder by induction effect of the conductive surface is energized. This increases the range of the signal.
  • the phenomenon described requires accurate placement of the transponder on the container. The marking method is correspondingly difficult in practice and, because of the use of active transponders, considerably more expensive in comparison to passive transponders.
  • EP 1 083 519 A2 also describes a fastening system for an active transponder - consisting of a feed element, a chip and an antenna - on a metal bottle or a metal container.
  • the transponder is attached to a collar on the bottleneck, for example that the flow element is removed from the bottle an air-filled distance d.
  • the transponder is mounted on a dielectric spacer, which in turn is attached to the metal container.
  • the attachment method to the container is not specified.
  • Active transponders have the advantage that they have a higher transmission range than passive transponders - but have the disadvantage that they have a shorter life and are significantly more expensive.
  • the applicability of the fastening system for passive transponders has not been tested in EP 1 083 519 A2.
  • the Finnish company Fa. UPM-Rafsec markets the so-called FlagTag transponder labels for the marking of metal containers.
  • the transponder is embedded like a flag in a label that is glued to a container / container.
  • the transponders are more or less perpendicular to the metallic object surface.
  • the transmission of the signal is carried out with suitable reading antennas (circulating antenna field) without interference, as long as the transponder antenna does not fold over and thus does not get too close to the metallic object surface.
  • suitable reading antennas circulating antenna field
  • the invention relates to the attachment of transponders on metallic or metal-containing objects by means of magnets, in particular magnetic film or vapor-deposited magnetic layers or incorporated in labels magnetic film.
  • the magnet does not adversely affect the reading properties of the transponder; the transmission of the signal takes place over a longer range without interference.
  • Other advantages of the magnet are that the transponder can be inserted or removed easily and non-destructively and thus reusable.
  • the transponder is mounted parallel to the surface and is therefore less prone to the stress of transport.
  • the fastening system according to the invention is suitable for plane as well as uneven, round or wavy surfaces of metallic or metal-containing objects.
  • the spacer and / or the filler material and / or the magnetic film or the magnetic layer consists of a flexible, flexible, non-rigid material.

  • the fastening system according to the invention is suitable for all types of transponders.
  • the transponders must be placed at a distance from the metallic / metalliferous surface of the objects to be identified. This distance depends on the object to be identified, sometimes a distance of 1 mm is sufficient, in other cases 20 to 30 mm may be required. The necessary distance also depends on the readers used, their antenna performance and on the reading distance and must be determined on a case-by-case basis.
  • the size of the transponder is not essential.
  • the transponder can be kept away from the metal or metal-containing object to be identified by means of spacers (air bridge) or by means of a spacer made of dielectric material, such as foamed material, cardboard, plastic, paper or even air. When Spacer also spring coils can be used. When used on round surfaces, flexible or slightly flexible spacers / filling materials / magnetic foil are recommended. Magnets, magnetic feet, magnetic foils or vapor-deposited magnetic layers may be attached to the spacer or spacer for easy adhesion to metallic objects.
  • This construction could be made as an integrated transponder, e.g. Paper or PVC labels, plastic card or cardboard transponders, wherein thin magnetic foil or a magnetic layer are embedded / vapor deposited in bendable ends of the transponder. By tilting the ends of the transponder, an air gap between the transponder and the metallic surface is achieved, spacers / filling material is not needed in this case.
