Definitions

  • the present invention relates to a compacting machine according to the preamble of claim 1 for compacting and binding a coil of wire.
  • wire encompasses metallic wires of thinner type as well as metallic wire rods.
  • each coil of wire produced in a rolling mill is normally laid in a rather loose condition in coils of essentially cylindrical configuration, which are then transported between different locations in the rolling mill by means of a hook conveyor with each coil of wire arranged in a horizontal direction hanging on a carrier hook which is axially inserted through the coil.
  • each coil is normally compacted between two compacting elements of a compacting machine and retained in the compacted condition by applying loops of elongated retaining members in the form of wires or straps around the compacted coil by means of binding devices included in the compacting machine.
  • a compacting machine according to the preamble of claim 1 is for instance previously known from US 3 633 492 A .
  • This previously known compacting machine comprises two opposite compacting elements which are horizontally moveable towards each other along guide rails in order to compact a coil of wire received in a space between the compacting elements and thereafter horizontally moveable away from each other along the guide rails in order to release the compacted coil after strapping thereof, wherein each compacting element is moveable along the guide rails by means of a power member in the form of a heavy duty hydraulic cylinder which is fixed to a foundation of the compacting machine.
  • the strapping of the compacted coil is carried out by means of strapping units, each of which comprising two mating strap track section halves which are moveable towards and away from each other by means of their own hydraulic cylinders independently of the compacting elements.
  • strapping units each of which comprising two mating strap track section halves which are moveable towards and away from each other by means of their own hydraulic cylinders independently of the compacting elements.
  • the object of the present invention is to provide a compacting machine of new and favourable design for compacting and binding a coil of wire, which in at least some aspect offers an advantage as compared to previously known compacting machines.
  • the compacting machine according to the invention comprises:
  • the bending moments caused by the first and second power members will be taken up by the rigid and stiff pressure frame formed by the two mating pressure frame parts, and the foundation of the compacting machine is therefore not subjected to these bending moments.
  • a foundation of reduced strength and cost may be used without detrimentally influencing the required alignment of any mating guide track sections included in the binding devices of the compacting machine.
  • the moveable pressure frame part makes it possible to bring the compacting elements into contact with a coil of wire by before the first and second power members are actuated in order to achieve the final compacting of the coil.
  • the required stroke length of the first and second power members is reduced, which in its turn implies that the dimensions of the power members may be reduced. If power members in the form of hydraulic cylinders are used, the reduced dimensions of the power members also implies that the size of the associated hydraulic system may be reduced.
  • the first compacting element is configured to be in an advanced starting position on the first pressure frame part when the first pressure frame part is moved from the retracted position forwards towards a non-compacted coil of wire received in the space between the first and second compacting elements, wherein the first compacting element is configured to move rearwards in relation to the first pressure frame part from said starting position, under the effect of a rearwardly directed force on the first compacting element from the coil of wire and against the action of a forwardly directed force on the first compacting element from said first power member, during a final part of the movement of the first pressure frame part from the retracted position to the advanced position.
  • the first compacting element does not have to be moved rearwards in relation to the first pressure frame part by means of the first power member before starting a new compacting cycle.
  • the advanced starting position of the first compacting element may correspond to the final position reached by the first compacting element during the latest performed compacting cycle, and the time required for performing a compacting cycle may thereby be reduced.
  • the coil of wire will be somewhat compacted with a smaller compacting force under the effect of said forwardly directed force on the first compacting element from the first power member.
  • This initial compacting, in the following denominated precompacting, of the coil of wire implies that the required stroke length of the first and second power members for achieving the desired compacting of the coil is further reduced.
  • the driving device comprises an electric drive motor for effecting the movement of the first pressure frame part between said retracted and advanced positions.
  • the movements of the first pressure frame part may be achieved in a very rapid manner and the time required for performing a compacting cycle may thereby be reduced.
  • the movement of the first pressure frame part may be achieved in a simple and reliable manner.
  • the first and second pressure frame parts are provided with corresponding alignment members, which are configured to come into contact with each other in order to align the first pressure frame part with the second pressure frame part when the first pressure frame part is moved into contact with the second pressure frame part.
  • the alignment members will make sure that the first and second pressure frame parts are correctly positioned in relation to each other when they are brought into contact with each other.
  • the above-mentioned precompacting may be achieved by simultaneously moving the first and second pressure frame parts towards each other in a synchronized manner, and the time required for performing the precompacting may thereby be reduced, which in its turn implies a further reduction of the time required for performing a complete compacting cycle.
  • the second compacting element is configured to be in an advanced starting position on the second pressure frame part when the second pressure frame part is moved from the retracted position forwards towards a non-compacted coil of wire received in the space between the first and second compacting elements, wherein the second compacting element is configured to move rearwards in relation to the second pressure frame part from said starting position, under the effect of a rearwardly directed force on the second compacting element from the coil of wire and against the action of a forwardly directed force on the second compacting element from said second power member, during a final part of the movement of the second pressure frame part from the retracted position to the advanced position.
  • the second compacting element does not have to be moved rearwards in relation to the second pressure frame part by means of the second power member before starting a new compacting cycle.
  • the advanced starting position of the second compacting element may correspond to the final position reached by the second compacting element during the latest performed compacting cycle, and the time required for performing a compacting cycle may thereby be further reduced.
