Definitions

  • the invention relates to a device for removing the severed turns of a strapping of a press bale with a winding device according to the preamble of claim 1.
  • Winding devices for wires or tapes are known in various designs, but these known winding devices are not suitable for winding up the previously blown turns of the strapping of the press bale, because the turns of the strapping are in contact with the press bale and cannot be easily grasped by the winding device. In this context, it should be borne in mind that the bales are at least partially constricted by the strapping.
  • the invention is therefore based on the object of providing a device for winding up the severed windings of a strapping of a press bale, with the aid of which the severed windings can be reliably detected and wound up by the winding device. This is solved by the features of the characterizing parts of claim 1.
  • the subject matter of the invention is shown in the drawing, for example. Show it:
  • FIG. 1 shows a device according to the invention for winding up the severed windings of a strapping of a press bale in a schematic front view
  • FIG. 2 shows the gripper head in the engaged position
  • FIG. 5 shows a cross section through the gripper head on a larger scale
  • FIGS. 8 and 9 are schematic diagrams corresponding to FIG. 7
  • Fig. 12 is a view
  • FIG. 13 is a plan view of the overall arrangement of the wrapping device in a bale processing station.
  • the device shown has a frame 1 in the form of a portal, which bridges a bale conveyor 2 and one transverse to the conveying direction of the Bale conveyor 2 carries movable carriage 3, on which the winding device 4 is mounted on a vertical sliding guide 5 distributable.
  • the adjustment of the bale conveyor 2 bridges a bale conveyor 2 and one transverse to the conveying direction of the Bale conveyor 2 carries movable carriage 3, on which the winding device 4 is mounted on a vertical sliding guide 5 distributable.
  • the winder 4 is via a steep cylinder 6.
  • This winding device 4 is assigned two carriage-fixed guide rods 7, against which a press bale 8 conveyed by the bale conveyor 2 can be pressed, for example with the aid of pressure rods which, parallel to the guide rods 7, on a longitudinal carriage displaceably guided on the carriage 3 for a cutting tool for cutting through the individual turns 9 of the strapping of the baling 8 are attached.
  • a gripper head 10 is provided for the individual cut windings 9 of the strapping, which is mounted in an auxiliary slide 11, namely on a sliding guide 12, so that the gripper head 10 on the one hand over the auxiliary slide 11 movably mounted on the slide 3 in Longitudinal direction of the bale conveyor 2 and on the other hand can be adjusted in the vertical direction via a steep cylinder 13 along the displacement guide 12.
  • This gripper head has puncture teeth 14a and 14b arranged one behind the other transversely to the strapping and which are assigned to one another in pairs, the one puncture teeth 14a of the tooth pairs being arranged on a toothed rail 16 adjustable by a lifting cylinder 15 and the other puncturing teeth 14b of the tooth pairs being arranged on a toothed rail 17 fixed to the gripper head .
  • the puncture teeth 14a and 14b form cutting edges 18 which act like scissors on their flanks facing each other in the region of their tip, to which recesses 19 are connected on the tooth root side.
  • the arrangement is such that in the insertion position shown in FIGS. 2 and 3, i.e.
  • the gripper head 10 is now placed on the surface of the press bale 8 via the auxiliary slide 11, the puncture teeth 14a and 14b penetrate with their puncture tips into the press bale 8, a winding 9 of the strapping possibly located in the area of the insertion prongs being displaced into the tooth gaps .
  • the interacting insertion teeth 14a and 14b are moved against one another, the baling ball being cut through like scissors in the area of the cutting edges IS.
  • the winding 9 located in the area of a tooth gap is simultaneously through the recess 19 of the tooth flank of the
  • the guide rods 7 can protrude through the bale surface
  • Fingers 21 form a guide comb 22. When lifting the Turn 9 of the bale 8, the respective turn 9 is therefore performed between two fingers 21.
  • one of a guide rod 7 assigned to the guide rod 7 parallel sensor 23 is used, which is pivotally mounted about the axis of the guide rod 7 and is pivoted when bending the detected winding 9, so that a control switch 24 are actuated via this pivoting movement can, via which the application of the actuating cylinder 6 is initiated.
  • the winding device 4 has a rotatable winding head 25 which carries driver fingers 26, 27 and 28 protruding on the end face. Of these driver fingers, a driver finger 26 is arranged on a swivel arm 29 which is mounted coaxially to the axis of rotation of the winding head 25 and which acts against the force of a return spring 30 against the counterclockwise
  • Direction of rotation 31 of the winding head 25 following driver fingers 27 can be adjusted.
  • the driving finger 26 projects through a corresponding elongated hole 32 in the
  • the winding device 4 Since two or more turns 9 of the strapping can also be detected by the gripper head 10 if it has a corresponding detection area, the winding device 4 must also be able to wind up two or more turns 9 simultaneously. This is ensured if the driver fingers 26, 27 and 28 have at least a length which corresponds to the greatest distance between the outermost piercing teeth 14a and 14b of the gripper head 10.
  • the device can be brought back from the bale area into the basic position shown in FIG. 1 by moving the carriage 3 transversely to the bale conveyor 2, in order to remove the strapping of a new press bale 8 again to be able to move to the center of the bale.
  • the gripper device can also have gripper bars 37 and 38 according to FIG. 10, each bar carrying teeth 34a and 34b, respectively, which are provided with a cutting tip with cutting edges 36a and 36b, the cutting tips being in the form of congruent per se, but here in relation are formed on the two different gripper bars 37 and 38 in mirror image to each other, acute-angled triangles.
  • the gripper bars are shown before the working stroke and in this position the gripper teeth 34a and 34b form an acute-angled puncture tip, so that they can easily penetrate into the press bales in pairs.
  • the wires (strapping) 9 then hold a position between the puncture tips and are then moved into the closing recesses 39 during the working stroke changes when the teeth 34b are moved from position a to position b.
  • the cutting edges 36a and 36b of the adjacent teeth of the different strips overlap each other somewhat, so that a correct displacement process of one gripper strip relative to the other gripper strip is ensured.
  • the recesses 39 ' are formed by inclined inner edges of the teeth, with cutting tips of the teeth 35a and 35b also being provided here so that these gripper teeth can easily penetrate into the baling balls.
  • the advantage here is that all the winding wires lying in the area of the gripper teeth are practically also grasped and taken along by them. This does not apply to the area of the cutting edges in relation to FIGS. 3 and 10, so.
  • a cross slide 54 is slidably mounted on a portal 1 with the cross beams 1 'bridging the bale conveyors 2.
  • the drive can preferably be carried out by a hydraulic or pneumatic servomotor, not shown here.
  • Three longitudinal slides 47, 50 and 53 which are displaceable in the conveying direction of the bale conveyor are mounted on the cross slide.
  • the drive of this sled can also be done by Hydraulic or pneumatic servomotors, not shown here, which are articulated here at one end to the cross slide.
  • the longitudinal slide 50 of the gripper device 10 carries a guide bar 55 which is perpendicular to the plane of the bale conveyor and on which the guide piece 59 of the gripper device 10 is held.
  • the gripper device 10 is driven in the vertical direction in accordance with the double arrow indicated, likewise by a hydraulic or pneumatic servomotor, not shown here.
  • Carriage 47 for the guide piece 48 of the wrapping device 4 ' carries a vertical guide bar 12' which is perpendicular to the level of the bale conveyor and which is arranged above the highest height of the pressed bales. Furthermore, stops 7 'in the form of bars perpendicular to the plane of the bale conveyor are provided on this longitudinal slide.
  • the cross slide 54 On the other side of the cross slide 54 there is a further longitudinal slide 53, which likewise carries counter supports or stops 51, 52 which are oriented perpendicular to the plane of the bale conveyor. They lie like the stops 7 'in a plane parallel to the path of the cross slide 54.
  • the waste paper bale 8 is aligned in the conveying direction of the bale conveyor or transversely thereto.
  • edge holders 44 protrude from the transverse sides of the bale conveyor 2 from over the bale conveyor and rest with their front edge on the bale 8. They are displaceable by hydraulic, pneumatic or also electrical drive means, also not shown here, in accordance with the double arrows shown.
  • the separating device is not shown in these figures, but can preferably be attached to the longitudinal slide 50 of the gripper device 10. In position I indicated by the dash-dotted line, it is intended to cut the winding wires.
  • This separation device is preferably a measurement be water device, but can also be a grinding wheel. It should then be mounted vertically, ie perpendicularly to the plane of the bale conveyor, in a guide bar corresponding to the guide 55 by means of a hydraulic or pneumatic servomotor, in order to sever the strapping successively at different heights.
  • edge holders 44 and counterholders 51 and 52 are now assigned to position sensors.
  • Such encoders are known as incremental encoders from Haidenhain,
  • the procedure for wire unwinding proceeds as follows:
  • the bale conveyor is stopped by a light barrier, not shown, when a bale is in the unwiring station, ie between the cross bars 1 '.
  • a further light barrier attached to the cross slide 54 stops it in the central region of the bale.
  • the carriage 47 of the winding device is then moved up to the press bale until the stop rods 7 'rest against it.
  • the counterholders 51 and 52 and finally also the edge retainers 54 are also applied to the baling by means of longitudinal slides 53.
  • the wires are cut in the position I indicated by dash-dotted lines, either one or in general two, perhaps also all of the wires.
  • the wire cut in each case is gripped by means of the gripper device 10 by moving the slide 50, whereupon the corresponding wire is lifted from the press bale by pulling back the slide 50 and fed to the winding device 4 ′, that is to say is guided into the area of the winding rods 56.
  • the dimensions of the bale are determined in cross-section and the path of the winding device 4 'along the circumference of the bale is determined by means of an electronic evaluation circuit. This can also be done in such a way that certain steps in size are preprogrammed corresponding path sections.
  • the wrapping device 4 ' is guided transversely to the bale conveyor, ie here in the longitudinal direction of the baling press, by means of cross slides 54 and in the direction perpendicular thereto through the carriage 47 of the wrapping device.
  • the winding device 4 ' is guided at a certain distance from the surface of the bale.
  • the speed of rotation of the winding rod 56 is adapted to the translatory travel, so that a "tight" winding is possible.
  • the counterholders 51 and 52 and the edge holders 44 must have been pulled back into the outermost position, ie to the edge of the frame 1. If only one or two winding wires are detected in a process, the bypassing of the baling must of course be repeated accordingly.
  • the stripping of the wires can be carried out after each time or in total for all wires of a press bale at the end of the unwiring, when the cross slide 54 has been moved into an edge position, so that the wire balls can be thrown off individually or at all by stripping on a stripping plate 57.
