Definitions

  • the invention relates to a de-wiring device for bales, in particular for cellulose, waste paper, fabric bales or the like, consisting of cutting devices for cutting through the strapping wires stretched around the bale and removal devices for removing the cut wires.
  • a cutting device is arranged on one bale side and a removal device is arranged on the opposite bale side. After removing the wires running around these sides, the bale is lifted off the rollers of a roller conveyor with a lifting device and rotated through 90 °, lowered and unwired on the two corresponding adjacent sides.
  • cutting and removal devices are arranged on all sides of the bale, so that the lifting and turning of the bale is saved. With such devices, however, it is necessary to position the bale precisely. In addition, the cutting and removal devices lying in the running direction of the bale must be able to be lowered under the plane of the roller conveyor.
  • the invention is therefore based on the object of providing a wiring device in which the bales can be wired safely in a short time with little outlay in terms of device technology.
  • the removal devices are formed by at least one clamping device for searching, holding, removing and disposing of the tying wires, that the clamping device consists of two or more legs that can be moved relative to one another, between which the tying wires can be clamped, and that Opening and closing of the clamping device an adjusting device is provided.
  • the clamping device When using the wire removal device according to the invention, the clamping device is located opposite a cutting device. At the beginning of the wire removal, the clamping device searches for the wire to be cut and removed and clamps it between the two movable legs. The cutting device arranged on the opposite side then cuts through the wire, which is now pulled off the bale by means of the movable clamping device, for example placed in a wire container or fed to a chopping device.
  • one of the movable legs of the clamping device can be provided with a hook-shaped finger for engaging behind the tying wires, the hook-shaped finger projecting over the opposite leg in the open state of the clamping device in the direction of the bale.
  • recesses can be formed on the inside of the legs facing the wire, which allow the wire to be positioned and held securely, non-positively and positively.
  • the hook-shaped finger must reach into the surface of the bale to securely reach behind the wire.
  • a cutting-like edge can be present on the wire-facing side of the projecting finger.
  • the clamping device While the hook-shaped finger grips behind the wire, the clamping device is moved further in the direction of the finger along the ball side. As a result, a force is exerted on the hook-shaped finger, which is preferably compensated for by a resilient pretensioning of the leg, the leg rotating to the rear about an axis of rotation.
  • the adjusting device can be, for example, a hydraulically movable cylinder, which causes the legs to be closed by moving out the inner plunger.
  • the cutting device arranged on the opposite side cuts through the wire.
  • the clamping device which is preferably arranged on the working arm of a robot, then pulls the clamped wire away from the bale by the movement of the robot arm and disposes of it after the clamping device has been opened beforehand.
  • the clamp attached to the robot's working arm pivots to the next wire, passing through the electronic viewfinder is positioned.
  • the working arm of the robot the control of which is preferably freely programmable, makes it possible in a simple manner to pivot the clamping device to the adjacent side surface of the bale, where the wire removal process can be completed.
  • bales can be unwired safely in a short time with little outlay on equipment.
  • FIG. 1 shows a possible embodiment of the de-wiring device using the example of a feed line from cellulose bales 1 to a pulper.
  • the bales 1 run via a roller table 2 to the de-wiring device.
  • the bales 1 are provided with a total of 4 tying wires 8, which cross each other at right angles and each tie two sides and the upper and lower surface of the bale.
  • a lifting and rotating device 5 is arranged behind the wire removal device, so that the feed line can also be provided with another wire removal device or other units that require lifting and rotating the cellulose bales 1 if required.
  • the actual unwiring device consists of a cutting device 6, a clamping device 7 and a robot 3, which is provided with a working arm carrying the clamping device.
  • the cutting device 6 and the clamping device 7 are arranged on opposite sides of the bale to the side of the roller table 2.
  • a wire container 4 In the swiveling range of the working arm of the robot 3 there is a wire container 4, into which the wires 8 which have been severed and removed from the bale 1 can be placed.
  • FIG. 2 shows the top view of the clamping device 7 in the open state.
  • the clamping device 7 is pivotally arranged on the working arm of the robot 3, not shown.
  • the legs 9 and 10 provided for clamping the wire 8 are movably seated on a common axis of rotation 13.
  • the upper clamping leg 9 is resiliently biased by a spring 15 which is arranged between the leg and a limit switch 16.
  • the leg 9 has at its front end directed towards the bale a hook-shaped curved finger 11 with an inner cutting edge 14 for reaching behind the wire 8.
  • the lower leg 10 is pivotally mounted about the axis 13 by means of a hydraulic cylinder 12 with which it is articulated.
  • FIG 3 the clamping device 7, a bale 1 to be wired with a tying wire 8 and a cutting device 6 are shown.
  • the opened clamping device 7 has penetrated into the surface of the ball 1 by lateral pivoting in the direction of the arrow with the hook-shaped finger 11 and the cutting-like edge 14 of the leg 9 and engages behind the lacing wire 8.
  • the leg 9 pressed backwards against the spring force of the spring 15 and actuates the pressure-sensitive switch 16, which is coupled to the hydraulic cylinder 12.
  • the hydraulic cylinder 12 moves the leg 10 out about the axis of rotation 13 against the pivoting direction of the clamping device 7 and thus causes the strapping wire 8 to be clamped between the legs 10 and 9.
  • By closing the legs 9 and 10 a does not produce pulse generator shown to the cutting device 6 an electrical pulse.
  • the cutting device 6 is activated and cuts the lacing wire 8 on the side opposite the clamping device.
  • the control of the clamping device 7 receives an electrical pulse and pulls the cut and clamped wire 8 away from the bale 1 by pivoting.
  • the wire 8 is then disposed of in the wire container 4 located next to the robot 3 after the clamping device 7 has opened (see FIG. 1).
  • the clamping device 7 swings back to the bale 1 in order to continue the unwiring process in the manner described above.
  • the robot arm of the robot 3 swivels the clamping device 7 to the adjacent side and ends the unwiring process there after a cutting device 6 has cut the tying wires 8 on the opposite side of the bale 1.
