Definitions

  • the invention further relates to a method for cutting and removing strapping wires from a square bale strapped therewith.
  • Such a device is from the EP 2 759 483 known.
  • square bales covered with binding wires are fed in a horizontal position on an endlessly rotating conveyor belt to a gripping and cutting station.
  • the cutting and gripping station has a cutting device and a clamping device.
  • the cutting device is aligned vertically to cut horizontal binding wires on the square bale.
  • a cutting bar is provided as the cutting device and is equipped with a plurality of fixed knife elements arranged at a distance from one another. In addition to the fixed knife elements, there are movable knives that can move towards and away from the fixed knives. If a packaged good reaches the gripping and cutting station, the cutting bar is moved towards the square bale, so that the fixed knife elements penetrate into the square bale.
  • the clamping device is arranged on the opposite side of the packaged goods in the gripping and cutting station. This is also essentially vertical.
  • the clamping device has a clamping bar and, in turn, like the cutting bar, has fixed fixing elements, a space for the introduction of the binding wires being provided between adjacent fixing elements.
  • This Fixing elements are assigned to grippers that can be moved relative to the fixing elements. If the square bale is in the gripping and cutting station, the clamping bar can be moved towards the square bale, so that the fixing elements penetrate the square bale and first fix the square bale together with the fixed knife elements, the binding wires penetrating into the open space.
  • the fixing elements of the clamping bar are designed so that they protrude from the clamping grippers. In this way, the fixing elements should be able to penetrate the packaged goods without impairing the mobility of the clamping grippers.
  • the sections of the binding wires that enter the intermediate spaces when the fixing elements penetrate into the square bales can thus be gripped.
  • the binding materials can be cut by the cutting device, after which the clamping device further holds the binding materials overall and moves them away from the square bale.
  • the object of the present invention is to alleviate or eliminate at least individual disadvantages of the prior art.
  • the invention aims to enable the strapping wires to be gripped and pulled off more reliably.
  • the wire holding and wire withdrawal device a plurality of wire deformation elements to form U-shaped deformations on the strapping wires.
  • the wire holding and wire take-off device is designed to bend the strapping wires at three locations in each case in such a way that U-shaped deformations are generated.
  • U-shaped deformations make it easier to pull off the strapping wires, since a positive connection between the wire retaining device and the U-shaped deformations can be produced on the strapping wires.
  • This advantageously prevents the strapping wires from slipping when being pulled off the square bale, even at high tensions. This provides a significant improvement over the prior art, in which the strapping wires are simply clamped, i.e. are held frictionally. It is also advantageous that the deformation forces for the formation of the U-shaped deformations can be comparatively low.
  • all location and directional information such as “up”, “down”, “horizontal”, “vertical”, “up”, “down” etc., relate to the intended operating state of the device on a horizontal work surface.

  • a set of movable wire deformation elements is arranged between a first arrangement of fixed wire deformation elements and a second arrangement of fixed wire deformation elements, the set of movable wire deformation elements to form the U-shaped deformations is movable on the strapping wires relative to the first and second arrangement of fixed wire deformation elements.
  • the movable wire deformation elements are between a receiving position moved away from the fixed wire deformation elements, in which the strapping wires can be received between the movable and the fixed wire deformation elements, and a bending position to be moved onto the fixed wire deformation elements, in which the strapping wires between the movable ones and the fixed wire deformation elements are bent into a U-shape, can be transferred.
  • a transverse drive is preferably provided for moving the movable wire deformation elements between a first position (receiving position) for receiving the strapping wires and a second position (bending position) for forming the U-shaped deformations on the strapping wires.
  • the transverse drive is preferably set up to move the movable wire deformation elements in a direction parallel to the facing outside of the square bale, in particular substantially perpendicular to the wire deformation elements, on the facing outside of the square bale.
  • a transverse linear drive in particular a hydraulic linear drive, is preferably provided, which jointly moves the movable wire deformation elements from the first (receiving) position to the second (bending) position and vice versa emotional.
  • the set of movable wire deformation elements by hooks on a base plate and / or the first arrangement of fixed wire deformation elements by the first Projections on a first base plate and / or the second arrangement of fixed wire deformation elements is formed by second projections on a second base plate.
  • the positioning device has a positioning groove which is essentially V-shaped in cross-section and has a first contact surface for a first outside and with a second contact surface for a second outside of the square bale, the cutting device having a first cutting element for cutting open the strapping wires on the first The outside of the square bale and a second cutting element for cutting open the strapping wires on the second outside of the square bale, wherein the wire holding and wire pulling device has a first wire holding and wire pulling module for holding and pulling out the strapping wires on a third outer side of the square bale and a second wire holding and wire pulling module for holding and pulling the strapping wires on a fourth outside of the square bale.
  • the V-shaped design of the positioning channel also ensures that loose material from the wired square bale does not fall out of the positioning channel.
  • the square bale can be freed from the strapping wires in a single processing position, ie without pivoting or turning.
  • the square bale is arranged in the V-shaped positioning channel.
  • the positioning trough can also be designed as a transport trough in which the square bale is transported, preferably in the horizontal direction.

  • the cutting device has a first and a second cutting element, which is moved towards the first or second outside of the square bale in order to cut through the sections of the strapping wires which are extended there.
  • the strapping wires are held and pulled off on the third and fourth outer sides of the square bale, ie on the upper side of the square bale.
  • two sets of strapping wires which are preferably guided perpendicular to each other around the square bale, can be cut open, held and pulled off without having to change the rotational position of the square bale. This enables a particularly simple, reliable and inexpensive removal of the strapping wires.
  • first contact surface and the second contact surface of the V-shaped positioning channel are each arranged at an angle of essentially 45 ° to the horizontal.
  • the V-shaped positioning channel has a first recess on the first contact surface for the passage of the first cutting element and a second recess on the second contact surface for the second cutting element of the cutting device to pass through.

  • the first and second cutting strips are preferably simultaneously against the strapping wires on the underside of the first and the second outer side of the square bale, so that the strapping wires are stretched beyond the yield point and therefore tear off.
  • the first and second cutting strips advantageously do not have to have sharp blades. This will reduce costs. Since resharpening of the first and second cutting bars is preferably not absolutely necessary, the maintenance intervals are also increased.

  • the first and second cutting strips are preferably in parallel vertical planes, in particular directly next to one another, i.e. Back to back, arranged.

  • the first cutting bar preferably extends essentially over the entire width of the first outside of the square bale.
  • the second cutting bar preferably extends essentially over the entire width of the second outside of the square bale.
