Definitions

  • the invention relates to a conductor loop which is embedded in a polymeric, in particular elastomeric material and is present in a strand construction comprising a single strand or multiple strands, with each strand again consisting of at least two individual wires, in particular as a component of a conveyor belt which has a supporting side, one Includes running side and an embedded strength member, wherein the conveyor belt is provided with at least one conductor loop.
  • a conductor loop which is embedded in a polymeric, in particular elastomeric material and is present in a strand construction comprising a single strand or multiple strands, with each strand again consisting of at least two individual wires, in particular as a component of a conveyor belt which has a supporting side, one Includes running side and an embedded strength member, wherein the conveyor belt is provided with at least one conductor loop.
  • the conductor loops usually consist of meandering metal cords, in particular steel cords.
  • the cords usually consist of at least five strands.
  • a 7X7 cord construction with a single wire diameter of approximately 0.2 mm and a total diameter of approximately 1.5 to approximately 2 mm is preferred.
  • a version consisting of a solid copper wire covered with steel strands is also known.
  • the meandering installation (DE 196 07 867 A1, Fig. 1) is necessary in order to increase the elasticity of the loops, otherwise they are due to the mechanical Stress in the conveyor belt, namely bending stress and loading stress, would be destroyed after a relatively short time.
  • Manufacturing the meanders requires the use of a relatively ductile material, which has a negative effect on the life of the loop. Materials with higher elasticity improve the fatigue strength of the single cord considerably, but make it difficult to shape it in meanders.
  • the object of the invention is to provide a highly flexible and highly stretchable conductor loop with an improved service life, which facilitates the shaping of the meanders or in which meandering can be dispensed with.
  • An increase in the service life and a considerable improvement in the elongation behavior of the new conductor loop can be achieved by reducing the individual wire diameter, which is preferably 0.01 to 0.2 mm, and by changing the structure of the starting material for the production of the conductor loops.
  • the elasticity is so good that meandering is not necessary.
  • This shaping or loosening of the loop construction can be achieved, for example, in that a steel cord, preferably in a HE construction, is broken down into its individual strand components.
  • the formed strands can be used individually as well as double or triple strands. This creates an open, stretchable conductor loop, in which the polymeric material (e.g.
  • loops which are concentrically arranged at a relatively short distance from one another can also be used.
  • the spacing of the loops thus arranged can be between one and fifty times the diameter of the individual strand.
  • connection can also be produced in that the loops are fixed on a carrier fabric, in particular by sewing on, gluing on, vulcanizing on or clamping on. If the connection consists of an electrically conductive material, it can be achieved that single wire breaks or strand breaks reduce the electrical resistance of the overall loop, which consists of several individual loops, less than if an entire single loop fails. In any case, the connection should preferably consist of an expandable, flexible material or of thin threads or yarns, which is used in thin layers from a few tenths of a millimeter to a thickness of 1.5 mm.
  • a spiral installation of the strand helix is also possible.
  • Such a shape does not have to be made endless by splicing, but the connection between the beginning and end of the strand helix can also be made using a flexible, thin and electrically conductive material.
  • connection curing adhesives that can also form an electrically conductive film.
  • Suitable materials are, for example, modified polyester or epoxy resins, but also polyurethane, silicone, thermoplastic elastomer or rubber materials (for example highly conductive rubber).
  • the modification to achieve sufficient electrical conductivity can be carried out by admixing electrically conductive materials such as metal powder, carbon black and / or conductive polymers in sufficient concentration.
  • electrically conductive materials such as metal powder, carbon black and / or conductive polymers in sufficient concentration.
  • nanoscale metallic fillers made of silver, nickel, aluminum or also silver-plated or gold-plated nickel, which give good conductivities even in relatively low concentrations, are particularly suitable for this purpose.
  • organic metals conductive polymers
  • a combination of different fillers or filler types is also possible to achieve sufficient electrical conductivity.
  • connection of the individual loops or loop segments by means of the same or a similar strand as that from which the loop is made and their fixing with a suitable adhesive material is possible in addition to the known connection techniques such as soldering or by means of crimp sleeves.
  • the endless loop of the conductor loop (splice production) and the connection of the loop segments and partial loops can be carried out by simply interlacing the open strands in a manner similar to normal splice production for steel cords or by soldering or using ferrules. It is not absolutely necessary to fix this splice; it is sufficient if the splice length is long enough.
  • the polymeric material in which the conductor loop is embedded or a suitable, flexible adhesive fixes it. The use of an electrically conductive material is also optimal for this purpose.
  • the loop can be fixed at several points (especially at the deflections) on this fabric by gluing or sewing on with a textile thread. This ensures that the geometry of the loop does not change uncontrollably and undesirably during further processing.
  • the fabric with the conductor loop is then preferably installed in the conveyor belt in such a way that the side of the fabric on which the loop is located is placed inwards (towards the core).
  • This measure also serves to improve the service life of the conductor loop, since it reduces the stress caused by exposure; because the fabric lying towards the cover plate will absorb a large part of the applied energy of the conveyed material or spread it over a larger area and thus protect the loop.
  • the tissue must have a preparation to achieve good adhesion to the embedding polymer.
  • the conductor loops are usually installed in a rectangular shape with rounded corners, usually two loops being arranged concentrically to one another. Under certain circumstances, it may be advantageous to deviate from the rectangular shape and to form the loops, for example, as an oval or circular, wherein a concentric arrangement of two or more loops is also possible here.
  • a special form is the previously described spiral arrangement, which can also be made elliptical or quasi circular.
  • Figure 1 shows a steel cable conveyor belt with a conductor loop on the carrier fabric.
  • Fig. 5 is a conductor loop on carrier fabric with corner fixation.
