Definitions

  • the invention relates to a device for removing the strapping of a press bale in accordance with the preamble of patent claim 1.
  • Such a device is known from US-PS 35 13 522. It is provided to cut the individual winding wires in a targeted manner by means of scissors interacting with one another, to bundle them with a gripper device and to grasp and wind them up as a bundle by a winding device. All processes take place in relation to a single side of the ball, ie above the bale. For this purpose, of course, the separating device and the gripping device are mounted on the bale surface in the frame. In this case, the wrapping process should be quite difficult, since the bale rests on the wires. The detection of the wires by the knife devices is also problematic, since each of them has only a limited radius of action. The bundling of the wires is also not easy, since the wires are often buried in the bale so that they are difficult to grasp.
  • the object of the invention is to provide a device which ensures a perfect, accurate gripping and grasping of the strapping both by the separating and the wrapping and the gripping device completely automatically, without an over-precise bale alignment being necessary.
  • the separating device has scissors-like interacting knives that cut the baling bales without gaps either in one operation or in successive sections across its strapping, all are in
  • Gripper copies and two guide rods that can be pressed on both sides of the gripper head on the press bales transversely to the strapping can meet the requirement for a safe grasping of the cut windings by the winding device
  • the gripper head pulls the detected windings between the two guide rods in a loop-forming manner from the press bale, so that the windings between the guide rods and the gripper head have a pre-timed yeriauf which allows the winding device to be positioned securely with respect to the individual windings.
  • the severing of the individual turns regardless of the respective turn position due to an incision of the press bale extending over the entire strapping area or a gapless cutting sequence extending over the strapping area enables a simple connection of the device in connection with the winding-appropriate removal of the severed turns between two guide rods a bale conveyor of any design, without removing the bale from the bale conveyor and positioning it in relation to the device
  • the frame needs to have a portal bridging the bale conveyor, which carries a cross slide, with the aid of which the separating device and the wrapping device can be moved over the bale conveyor in order to remove the strapping of the press bale lying on the bale conveyor in the effective range of the cross slide.
  • At least one of these devices can be assigned to a longitudinal slide mounted on the cross slide, via which the required partial movement can be carried out. If the separating device and the winding device are each constructed on a longitudinal slide, these two devices can be moved towards the baling bale from opposite sides. The provision of two longitudinal slides is not necessary, however, if the longitudinal slide for the one pushing device running transversely to the strapping for positioning the baling bale against the respective other device, because in this case the baling bale over the longitudinal sledge to the opposite device for severing or to the
  • Winding the turns is pressed.
  • the guide rods can simultaneously serve as push rods for moving the baling bale on the conveyor.
  • the guide rods assigned to the winding device and held non-displaceably in the cross slide can be designed as counterholders for the pressed bales pressed by the pressure rods of the longitudinal slide.
  • the separating device can be provided between the push rods via which the severed ends of the individual turns are held pressed against the baling.
  • the guide rods or the pressure rods can form a guide comb for the individual windings of the strapping, which prevents the individual windings from sliding off along the pressure rods or the guide rods and secures the respective winding position when the severed windings are pulled off the press bale by the gripper head.
  • the scissors which interact in a scissor-like manner, must penetrate into the surface of the press bale, specifically across the strapping.
  • the feed movement required for this can advantageously be achieved in that the separating device is mounted on an auxiliary slide which can be moved in the direction of the longitudinal slide, the travel of which determines the path of penetration of the knives into the bale.
  • a sliding guide running transversely to the strapping can be provided for the separating device on the auxiliary slide.
  • the bale is not cut in one operation over the entire strapping area, but only over a partial area.
  • this measure requires a gradual adjustment of the separating device on its sliding guide in accordance with the total cutting length of the knife across the strapping.
  • the gripper head assigned to the winding device is ver on a in the longitudinal direction on the cross section arranged slidably mounted auxiliary carriage, so the gripper head can be easily placed on the baling over this auxiliary carriage and then the winding detected by the gripper head can be lifted from the baling bale.
  • the winding device When the separating device is mounted on a longitudinal slide, the winding device need not be moved in the adjustment direction of this longitudinal slide. It is sufficient if the winding device is adjustably mounted on a sliding guide arranged on the cross slide and extending transversely to the strapping, in order to be able to securely grasp the turns of the strapping that are lifted from the bale. Regardless of the respective altitude, each turn can be tangled by a corresponding adjustment of the winding device parallel to the guides or transversely to the strapping by the winding device, because the course of the turns between the guide rods and the gripper head in a projection parallel to the guide rods is set.
  • the gripper head can also record all of the turns possibly located in its area of extension in an analogous manner to the separating device.
  • This training course also allows an idle stroke for the gripper head if there is no turn of the strapping in its grip area.
  • one of the two guide rods can be assigned a sensor for the turns of the strapping which are gripped by the gripper head and lifted off the baling press.
  • the deflection of the windings on the guides wrangles during the loop-forming lifting through the gripper head causes the windings to strike the sensor, which indicates the lifting of at least one winding and emits a corresponding control signal for driving the winding device.
  • the subject matter of the invention is shown in the drawing, for example. Show it:
  • Figure 1 shows a device according to the invention for removing the strapping of a baling in a schematic plan view.
  • Figure 2 shows this device in a cross section.

  • the device for removing the strapping of a press bale essentially consists of a part 1, which has a portal 3 bridging a bale conveyor 2 with a cross-section 4, from a separating device 5 for the individual turns 6 of the strapping of the press balls 7 and from a winding device 8 for the severed turns 6 of the strapping.

  • the separating device 5 forms a cutting head with two cutter bars 20 and 21, of which one cutter bar 21 can be adjusted relative to the other cutter bar 20 with the aid of a drive cylinder 22, so that the cutters 23a assigned to one another in pairs and 23b interact with their cutting edges facing one another like scissors, which allows a spark-free severing of the usually metallic strapping. This is of particular importance with regard to the flammability of the pressbals.
  • the knife arrangement is such that, when the associated knives 23a and 23b are in the open position, the neighboring knives of the knife pairs at least partially overlap one another and form a common puncture tip. If the separating device 5 is now pressed onto the press bale 7 by acting on the cylinder 16, the puncture tips of the knives 23a and 23b, which partially overlap one another, penetrate into the surface of the bale, the turns 6 of the strapping possibly located in the area of the separating device 5 There are gaps between the puncture tips because they penetrate these gaps when the puncture tips penetrate along the back of the knife be pushed off. During the subsequent cutting stroke of the knives 23a of the knife bar 21, the windings located in a gap between the teeth are severed. The separating device 5 can therefore be pulled out of the bayonet engagement and offset to the engagement length again
  • Press bales 7 are set in order to cut the bale 7 transversely to the strapping, that is to say with respect to the strapping in the axial direction, which results in cutting all the turns 6 of the strapping without knowing the position of the individual turns 6.
