Definitions

  • the invention relates to a coil former, in particular a bobbin for receiving at least one longitudinal element that can be wound up or unwound from the latter, with a drum and a wall element on each side.
  • Such bobbins and in particular bobbins are well known. These are particularly suitable for winding up heavy ropes and electric cables and are therefore dimensioned, for example, with a drum diameter of 2.6 meters and on the outside with a diameter of 4.6 meters for the round wall elements. This means that these bobbins can weigh more than 4,000 kg.
  • the ropes or electric cables are unwound from these bobbins after being laid, the latter are transported, for example, from the laying location back to the place of manufacture, and a finished rope or cable is consequently wound up there again.
  • U.S. 1,905,488 discloses a drum with a ring and, on both sides of this, a wall each consisting of 8 sections, each of which is composed of a frame and a reinforcing profile, each with radial openings. These frames also have openings on the outside for attaching struts as cladding. These reinforcing profiles are inserted inside the frames or removed from them in the released state. These several components, namely the ring, the flange, these profiles and the frames must be precisely matched so that they can be screwed together. In addition, these struts forming the formwork are fastened to the outside of the frame.
  • a coil device in which cylindrical segments are connected to end discs.
  • the segments are connected by dovetail-shaped connecting means attached to each other while being connected to the side end plates by hooks and clasps.
  • Separate components are also provided as disc segments and triangular disc elements.
  • outside of the end disks there are radially extending struts arranged in the shape of a wheel with an inner and outer ring, the latter being supported on wheels and on which the spool can be rotated.
  • the invention is based on the object of creating a bobbin of the type mentioned at the outset, through which empty transport can be simplified and thus carried out more cost-effectively.
  • Forming the drum and the two wall elements of the bobbin each from several assembled segments allows the bobbin to be dismantled, in particular for empty transport, and easily reassembled at the production site of the longitudinal elements and prepared for the next loading. In this way, the expenses and costs can be adapted or optimized to the transport conditions.
  • one or more supports are assigned, in which the segments can be releasably attached to one another by fastening means and are also mutually positioned, whereby assembly into a ready-to-use bobbin can be carried out quickly and efficiently.
  • Such bobbins according to the invention are particularly suitable for winding up steel cables, electric cables, hemp cables or the like, in which the outer diameter of the wall elements is several meters.
  • the drum and also the wall elements are expediently divided into four to eight segments, which are dimensioned in such a way that they are adapted to the dimensions of a standardized freight container, with segments from a number of coil formers being loadable into a freight container.
  • bobbin 10 for receiving at least one longitudinal element that can be wound up or unwound, which is not shown in detail.
  • a bobbin 10 At least one steel cable, an electric cable of any kind, a hemp cable or the like can be wound up, transported and unwound again at a laying location.
  • This bobbin 10 is usually provided with dimensions of two to six meters outside diameter and a width of one to six meters.
  • the bobbin 10 consists of a drum 15 and a closing wall element 11, 12 on each side.
  • a third wall element could also be provided in the central area of the drum 15 if, for example, two different longitudinal elements are to be wound up.
  • These wall elements 11, 12 are disk-shaped and thus allow the bobbin to roll.
  • the drum 15 contains a continuous central axle 14 which is mounted at least at both ends in a respective hub 18 of a preferably wheel-shaped rim 17 .
  • This axle 14 is expediently hollow, so that a shaft can be inserted through it, which can be adjusted on both sides on a bearing block or the like, so that the bobbin can be rotated on it for winding or unwinding the longitudinal element.
  • the drum 15 is composed of several partially cylindrical segments 15' that can be connected to one another and the two wall elements 11, 12 are each composed of several segments 11', 12' that can be fastened to one another, the latter being formed like a trapezoid and forming this disc shape when assembled.
  • this bobbin 10 In the exemplary embodiment of this bobbin 10, six segments 15', 11', 12' are provided for the drum 15 and the respective wall elements 11, 12 provided. A different number of these segments could of course also be selected depending on the size of the coil body and the existing requirements, but preferably between four and eight are advantageous.
  • the segments 15' of the drum 15 are each assigned a plurality of supports 18, 19 at the connection points, by means of which they are detachably fastened to one another with the adjacent segments 15' by means of fastening means and are mutually positioned.
  • the supports 18 form a support surface for the adjoining segment, so that they are mutually aligned after the connection and their abutting edges 15" are in contact with one another.
  • Screws 20, which can be screwed into these supports 18, 19 from the inside, are advantageously used as fastening means.
  • the supports 19 on the inside are provided with blind holes, so that the segments 15' have no holes on the outside and abut one another without play, as shown in FIG 2 is evident.
  • these segments 15' can advantageously be set up and pushed against one another without play and then screwed together, the screws being able to be screwed in by machine so that this can be carried out expeditiously.
  • the segments 11', 12' are each assigned an elongated support 21, 22, which corresponds to a bearing 23, 24 as a bearing surface on the outside of the segments 11', 12'.
  • the segments can be fastened to one another at the supports by means of fastening means, so that after connection they are mutually aligned and their abutting edges 11", 12" also lie against one another on the inside without play.
  • the screws 20 can be screwed into these supports 21, 22, with the supports on the inside also being designed with blind holes, so that the segments have no holes on the inside and abut without play, as is shown in 2 is illustrated.
  • the segments 11′, 12′ each have at least one support 24, 25 on the inside, which can be connected to a corresponding support 27, 28 on the outer circumference of a respective segment 15′ of the drum 15 by fastening means. It is provided that the two rims 17 supporting the axle 14 are fastened with the same screws 20 on the inside of the drum 15 .
  • the segments 11', 12' of the wall elements 11, 12 are each provided laterally with a guide groove 31 on the outer circumference, in which a lug 32 can be inserted as a connecting means of two adjacent segments 11', 12'. This provides additional reinforcement of the connection between the segments or the wall elements.
  • a respective package comprises a number of segments 11', 15', rims 17 and other individual parts, which are each preferably arranged on a non-visible linkage.
  • the segments of the drum and the wall elements are dimensioned or arranged into packages in such a way that they are adapted to the dimensions of a standardized freight container and segments from a plurality of coil formers can be loaded into the freight container 30 . This allows an optimal use of space in the freight container 30.
  • the segments 15' for the drum are stacked one on top of the other in the longitudinal direction of the freight container and the segments 38 of the wall elements as half disks. Such an arrangement is suitable for reels with a large diameter.
