Definitions

  • the invention relates to a de-wiring machine for bales, in particular for cellulose bales, consisting of a positioning device for the bales, a cutting device for cutting through the vertical tying wires stretched around the bales in the area of at least one vertical bale side surface, a gripping device with which the short ends of the tying wires are traced after severing from the bale and can be pivoted upwards about the upper bale edge, a winding device which detects all the raised short ends of the tying wires in the raised portion with a common fork-shaped, longitudinally displaceable winding mandrel and winds them up into coils, and one from a series of comb-like arranged guide fingers existing guide device for the wire ends, the guide fingers after lifting off the short ends of the severed tying wires and after moving the winding mandrel into its Horsp Position in the area between the winding mandrel and the upper edge of the bale and the long ends of the tying wires
  • a wire removal machine of the type mentioned is known from EP-A-281 942. With this known device bales can be reliably and automatically wired. However, problems arise when winding the wires.
  • the guide fingers sit directly on a pressing device which presses against the winding wire by means of a pressure roller. Due to the resulting wire winding, the pressing device is raised, so that at least in the final phase of the winding, when it comes down to a good feeding of the wire, practically no guidance of the wire end is guaranteed.
  • the invention is based on the object of improving the winding process and thereby creating more compact wire windings.
  • the guide device is designed as a separate stationary unit and is arranged at a distance from the winding mandrel directly in front of the upper bale edge, about which the short ends of the tying wires can be pivoted upwards with the aid of the gripping device.
  • the guide fingers are preferably seated on a common support rod, with which the guide fingers are held in their operating position.
  • the support rod can be arranged with guide fingers pointing downward, the lower ends of the guide fingers lying above that position of the gripping device in which their lifting strips come to rest on the ball surface for gripping the tying wires.
  • the lacing wires are each between two guide fingers, so that the lacing wires running onto the winding device are reliably guided.
  • the tying wires run below the support bar.
  • the support rod with the guide fingers is expediently rotatably mounted so that the row of guide fingers can be moved elastically resiliently from its position, for example in the event of a collision with the gripping device.
  • a pressing device is preferably provided, which can be placed against the winding mandrel during the winding process. As the winding grows, the pressing device is lifted somewhat from the winding mandrel.
  • the pressing device In order to be able to actuate the pressing device comfortably, it can sit on a pivotably mounted bracket with which the pressing device can be pivoted into its operating position during the winding process.
  • the pressing device can have a continuous bar, which on the side facing the winding mandrel e.g. is provided with a curve. During the winding process, the pressure bar first lies on the surface of the winding mandrel and then on the wire winding that is building up.
  • the pressing device can also be provided with a continuous roller on the side facing the winding mandrel.
  • guide pins arranged in a comb-like manner are preferably provided on the pressing device, which guide pins engage in the area between the winding mandrel and the gripping device during the winding process.
  • these guide pins perform approximately the same function as the guide fingers provided on the opposite side of the winding mandrel for the long wire ends.
  • the gripping device is preferably after the severing of the tying wires with the wire ends pivotable up to the level of the top of the bale, so that the tied off strapping wires lie approximately in a horizontal plane in the extension of the top of the bale when the winding mandrel runs in.
  • a hold-down bar running essentially parallel to this bale edge can be provided at a distance from the upper bale edge facing the winding device and can be lowered onto the top of the bale at least during the retraction of the winding mandrel. This measure forms a defined fixed point for the severed tying wires on the top of the bale.
  • a cellulose bale 1 of which only an upper corner area can be seen in the drawing, is brought into an exact operating position relative to the unwiring machine.
  • the bale 1 With the help of axially displaceable fixing mandrels, of which only the mandrel 2 can be seen in the drawing, the bale 1 is fixed in its operating position.
  • the upper fixing mandrels 2 sit on an upper cross member 3, which forms the upper region of the machine frame.
  • the wire removal mechanism includes a cutting device 4, a gripping device 5, a winding device 6, a series of guide fingers 7, a pressing device 8 and a hold-down bar 9.
  • the cutting device 4 consists of two elongated cutter bars 10 and 11, which are provided on their cutting sides with teeth arranged at regular intervals and can be moved back and forth relative to one another.
  • the two cutter bars 10 and 11 extend at least over that area of the facing bale side in which the strapping wires are to be cut.
  • the two cutter bars 10 and 11 sit with their holder 12 on a support frame 13, which in turn is horizontally displaceable on the upper cross member 3 in the direction of the bale 1 to and away from it.
  • At least two spaced-apart guide rods 14 are used for guidance, which are held in bearings 15 on the upper cross member 3 and can be pushed back and forth with the aid of a drive (not shown in the drawing).
  • a drive not shown in the drawing.
  • an inactive position of the cutting device 4 is shown, in which the cutter bars 10 are at a distance from the bale 1.
  • the gripping device 5 is arranged at a distance above the cutter bars 10 and 11 of the cutting device 4. Similar to the cutting device 4, it consists of two lifting slats 16 and 17 which are displaceable relative to one another and which are provided with blunt teeth which are arranged at equal intervals along their length and are undercut on the engagement flank, are parallel to the adjacent bale surface and are displaceable relative to one another in their longitudinal direction are.
  • the bracket 18 of the lifting strips 16 and 17 is seated on a pivot frame 19 which is pivotable about an axis 20.
  • the gripping device 5 While the cutting device 4 cuts the tying wires, the gripping device 5 lies with its lifting strips 16 and 17 at a distance above the cutter bars 10 and 11 against the corresponding bale surface and grips the tying wires with its gripping teeth. After cutting the tying wires, the gripping device 5 pivots into the position shown in the drawing, in which the lifting strips 16 and 17 lie approximately at the level of the top of the bale. In this position of the gripping device, the severed tying wires assume an approximately horizontal position in the area between the top of the bale and the gripping device 5.
  • the hold-down bar 9 which is pivotable about an axis 21, presses on the top of the bale and fixes the severed tying wires.
  • the hold-down bar 9 runs at a distance from the upper bale edge facing the winding device 6 and is essentially parallel to this bale edge.
  • the winding device 6 is actuated.
  • This consists of a longitudinally displaceable winding mandrel 22 which is fork-shaped and receives the tying wires with a central transverse slot 23.
  • the outer surface of the winding mandrel 22 is approximately cylindrical and serves to wind up the tying wires.
  • the guide fingers 7 located between the winding mandrel 22 and the bale 1 sit in a comb-like arrangement on a common support rod 24, with which they are held in a vertically downward position directly in front of the bale edge. During the winding process, the guide fingers 7 close the tying wires between them, so that they are guided for winding onto the mandrel 22 well aligned.
  • the support rod 24 is rotatably mounted about its longitudinal axis and is held in its operating position by means of an adjustable leaf spring, not shown in the drawing, so that the guide fingers can be deflected elastically from their position.
  • the pressing device 8 pivots into its pressing position.
  • the pressing device 8 consists of a bracket 25 which is pivotable about a horizontal axis 26. At its free end the bracket 25 is provided with a strip 27 which extends at least over the effective length of the winding mandrel 23 in which the wires are wound.
  • the strip 27 initially lies on the outer surface of the winding mandrel 22 below the transverse slot 23 which is initially horizontal.
  • comb-like guide pins 28 which protrude during the winding process into the area between the winding mandrel 22 and the gripping device 5.
  • the guide pins 28 guide the short wire ends coming from the left, so that these cannot be put across, but are guided in a straight line and can be wound up tightly.
  • the pressing device 8 pivots about its axis 26 to the left into its inactive position and the winding mandrel 22 moves back and strips off the wound windings which fall into a container located below the machine.
  • bales are to be wired which are held together by vertically crossing strapping wires, the entire device described is present a second time, namely offset by 90 ° to the first, so that all strapping wires of the bale are removed in a single operation can.
