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 severing the tying wires stretched around the bales, a gripping device with which the tying wires can be lifted off the bale after the severing, and a winding device for winding the cut wires.
  • Cutting devices (DE-PS 28 16 912) and winding devices (DE-PS 28 21 336) are already known for unwrapping bales. With the known cutting devices, the strapping wires can be easily found and severed, and with the known winding heads, the severed strapping wires can be easily wound up.
  • the cutting device is provided from a pair of scissors in which a separate pair of scissors is assigned to each individual wire.
  • the machine is used for unwrapping hay bales which are surrounded by three parallel wires. Accordingly, three scissors are provided, which are positioned at exactly the point in which a wire would normally have to run.
  • the tying wires often do not run at a precisely specified point, since they slip during transport of the bales or can be shifted far from their normal position due to improper handling.
  • the cutting leg of the scissors is made extremely long in order to cover a larger width when the wires are gripped, this presupposes that firstly a sufficient contact force acts on the scissor legs and secondly that the bale material is soft enough for the scissor legs to pass through the material can be pulled through.
  • the tying wires are often tightly stretched around the bale and are below the outer level of the outer surface of the bale.
  • the scissors shown in the cited publication are therefore only suitable for cutting through such tying wires which are stretched around relatively soft material, for example around a hay bale.
  • the known scissor device cannot be used to cut the tying wires of cellulose bales, waste paper bales or the like.
  • Such a gripping device can only be used if the bale material is sufficiently soft and the hook-shaped claws can be pulled through the outer region of the bale material in the manner of a plow. This may work for hay bales for which the known unwiring machine is intended; Gripping devices of this type are not suitable for bales of pressed cellulose or waste paper, for which the unwiring machine of the present application is intended.
  • the gripping device in the known unwiring machine is relatively complex, because two individual units are required which grip and lift the wires at locations spaced apart from one another.
  • the invention has for its object to make the wire stripping machine more versatile, and it should also be possible to wire it properly if a different number of strapping wires are arranged at different distances from one another and the individual strapping wires may have slipped sideways .
  • the barking machine for bales made of any material, including extremely hard material, should be applicable.
  • the cutting device has two elongated cutter bars, which are provided on their cutting sides with teeth arranged at regular intervals and can be pushed back and forth relative to one another
  • the gripping device is formed by at least one lifting bar unit, the lifting bars of which are provided with their Teeth are arranged at equal intervals, are parallel to the adjacent bale surface and are longitudinally displaceable relative to each other, and that the winding device detects the severed tying wires at the distance between the respective bale edge and the gripping device and winds them up into coils.
  • the cutting device consisting of the cutter bar, which is known from DE-PS 28 16 912, extends over the entire width of the bale and detects each individual wire, even if it runs obliquely or is displaced, and reliably cuts it. Only a very small stroke, which can be carried out with relatively low forces, is required for severing.
  • the gripping device is designed similarly to the cutting device, but the gripping teeth have no cutting edges.
  • the gripping device can also reliably grasp the wires, it doesn't matter how many wires are present and to what extent they are shifted from their desired position.
  • the gripping teeth can easily and reliably locate the wires and reliably grasp them relative to one another by only a slight displacement of the lifting strips.
  • the winding device is guided exactly through this plane, in which the severed individual wires are held by means of the gripping device.
  • the winding device reliably grips each individual lacing wire and winds it up into a very small individual coil.
  • the teeth of the gripping device preferably have flanks which are inclined obliquely backwards from the tooth on the gripping side, forming an undercut. As a result, the teeth pull the wires towards the base of the tooth when the lifting strips are moved and hold them securely.
  • the gripping device can be designed similarly to the cutting device according to DE-PS 28 16 912, but without cutting edges are formed on the teeth. Due to the strip-shaped, continuous gripping device, the wires are reliably gripped regardless of their position, pulled a bit into the teeth and then held.
  • a plurality of lifting bar units which are arranged next to one another, are offset in height relative to one another and overlap one another and can each be pivoted about an axis running parallel to the wires. This measure ensures that the lifting bar unit also adapts to a wavy surface of the bale and can reliably grip the tying wires. In the normal case, however, it is sufficient if a single lifting bar unit is provided which extends over the entire width of a bale.
  • the winding device expediently has at least one fork-shaped pickup, which is arranged between the bale and the respective gripping unit, is guided in a longitudinally displaceable manner parallel to the bale and can be rotated about its longitudinal axis.
  • a winding device can have a very simple construction, only the fork-shaped pickup needing to be guided through the plane in which the severed tying wires are held.
  • the fork-shaped pick-up can be a round bar profile which is seated at one end in a rotatable holder which can be glued in the longitudinal direction of the profile, the slot extending from the opposite free profile end approximately over a bale length into the profile.
  • the wires held by the gripper are not exactly in one plane.
  • the free slot end of the sensor can be widened.
  • a pressure plate that can be placed laterally against the fork-shaped pickup, at least in the area of the wires to be wound, can be provided. This ensures that the wires wind up tightly on the transducer.
  • the pressure plate can be pivoted about an axis parallel to the fork-shaped pickup, so that it can gradually pivot away from the pickup as the spool becomes larger.
  • Crosspieces are preferably arranged at intervals on the pressure plate, which are perpendicular to the pressure plate, are displaceably mounted perpendicular to the pressure plate on the side facing away from the fork-shaped pickup, and reach through slots in the pressure plate.
  • the crossbars serve to limit the coil width, so that the coils are not only narrow, but also narrow. if a crossbar meets the wire to be wound up when the pressure plate is placed on the transducer, the crossbar is pressed into the pressure plate so that this crossbar does not interfere with the winding of the wires.
  • the crosspieces are preferably spring-loaded in the direction of the fork-shaped transducer, so that no separate actuation mechanism for the crosspieces is required.
  • the winding device can also have a pressure roller which can be placed laterally against the fork-shaped pickup, at least in the area of the wires to be wound up, and which is spring-biased in the direction of the fork-shaped pickup.
  • a pressure roller which can be placed laterally against the fork-shaped pickup, at least in the area of the wires to be wound up, and which is spring-biased in the direction of the fork-shaped pickup.
  • protruding guide pins are provided on the holder of the printing roller in the area of the wires to be wound up on both sides of the printing roller at intervals, which laterally overlap the printing roller and the fork-shaped pickup when the printing roller bears against it.
  • the wires to be wound are guided approximately perpendicular to the fork-shaped pickup, so that there is no risk that the wires will slip out of the longitudinal slot at the beginning of the winding process.
  • the unwiring machine which is provided in particular for unwrapping cellulose bales, essentially consists of a positioning device 1 for the bales, a cutting device 2 for severing the tying wires stretched around the bales, a gripping device 3 with which the Lacing wires can be held and after the severing a piece can be removed from the bale, and a winding device 4 for winding the severed lacing wires.
  • the cutting device 2, the gripping device 3 and the winding device 4 are seated in a frame, not shown in the drawing, with which the individual units can be moved together in height.
  • the frame is located directly above the positioning device.
  • the positioning device 1 essentially consists of a roller table 5, on which the bales 6, which are still provided with their lacing 7, are moved up and positioned below the unwiring machine.
  • the bale has been stopped by actuating the limit switch 8 and pressed against the guide bar 9 with the aid of the slide 10, there is a vertical edge 11 of the bale regardless of the size and height of the bale Bale 6 in a certain position.
  • the individual units of the unwiring machine are aligned with this edge 11.
  • bales as shown in FIG. 5, are held together by four tying wires 7 crossing in one plane.
  • the cutting device 2, the gripping device 3 and the winding device 4 are oriented on the bale edge 11 which is respectively aligned by the positioning device 1, which are jointly attached to a frame (not shown in the drawing) and can be moved in the horizontal and vertical directions.
  • the cutting device 2 and the gripping device 3 are fastened to plate-shaped holders 12 which are arranged at right angles to one another, the plate-shaped holders 12 each being arranged opposite those vertical side surfaces of the bales 6 which adjoin the aligned bale edge 11.
  • the plate-shaped holders 12 can be moved back and forth relative to a frame plate 13, i.e. they can be moved against a bale in its aligned position and can be moved back again by the bale.
  • each plate-shaped holder 12 Cutting device 2 arranged.
  • the cutting device 2 can be designed similarly to the known cutting device according to DE-PS 28 16 912.
  • Two elongated knife bars 15 and 16 are seated in a housing-shaped holder 14 and have teeth arranged one behind the other at regular intervals on their cutting sides.
  • One of the two cutter bars is fixed, while the other cutter bar can be pushed back and forth, by means of a lifting cylinder 17 which can be seen in FIGS. 2 and 7 and is arranged on the rear side of the respective plate-shaped holder 12.
  • the gripping device 3 sits on a respective pivotable plate 18 which is arranged behind the respective plate-shaped holder, the gripping device 3 reaching through a recess 19 in the respective plate-shaped holder 12.

  • the lifting bar units 20 to 22 each consist of two lifting bars 23 and 24 which are displaceable relative to one another, of which the lower lifting bar 23 is fixed, while the upper lifting bar 24 is displaceable with the aid of lifting cylinders 25.
  • the lifting strips 23 and 24 are distributed at equal intervals along their length arranged teeth 26 and 27 are provided, the flanks 28 and 29 of which are inclined obliquely backwards from the tooth head on the gripping side, so that an undercut 30 is formed.
  • the cutting device 2 can also be constructed according to a similar principle, but the tooth flanks directed against one another must be provided with cutting edges in order to cut through the detected wires.
  • the three lifting bar units 20, 21 and 22 of the gripping unit 3 are each arranged pivotably about a central vertical axis 31, while the two lateral ends are supported against the pivotable plate 18 by means of compression springs 32. In this way, the lifting bar units can reliably rest against the bale surfaces, even if they are not level.
  • the same principle of the divided unit can also be implemented for the cutting device 2, so that these irregularities of the bale surface can also be adapted.
  • the plate 18 In order to pivot the plate 18 provided with the gripping device 3 relative to the plate-shaped holder 12, the plate 18 is pivotally mounted in its upper region about an axis 33 which is fixed relative to the plate-shaped holder 12 and can be driven via a lever construction 34 by means of a lifting cylinder 35.
  • the winding devices 4, which are assigned to each gripping device 3, consist essentially of a fork-shaped transducer 36, which is formed from a round rod profile provided with a central longitudinal slot 37.
  • One end of the transducer 36 is seated in a rotatable holder 38 which can be displaced in the longitudinal direction of the rod profile.
  • the slot 37 extends from the free end of the profile approximately over a bale length into the round rod profile.
  • the free end of the slot 37 is provided with a wedge-shaped widening 39 in order to be able to grip the wires more easily.
  • Each fork-shaped pick-up 36 is assigned a wiper 40 which is displaceable transversely to the respective pick-up 36 and overlaps it laterally with two legs 41.
