Definitions

  • the invention relates to a device for processing fiber bales with a reciprocating, toothed removal roller and one in front of and behind the removal roller arranged axially parallel to this, pressing on the bale surface tooth roller.
  • the fiber material is removed from the front front surface of a cuboid layer stack by means of a plucking roller fitted with needles, which is mounted on a horizontally movable carriage (DE-PS 1,193,844).
  • the aim is to prevent larger pieces from being torn out of the layer stack by retaining elements in the form of corrugated rollers which are arranged in the manner of drag rollers in front of and behind the plucking roller and are pressed against the front surface.
  • the retention force of such corrugated rollers is unsatisfactory, especially if the fiber material is removed from the bale from above.
  • the object of the present invention is to provide a device which makes it possible to safely limit the quantity taken off even without using grates and to keep it constant over the entire bale height.
  • the object is achieved in a device according to the preamble of claim 1 in that the toothed rollers are arranged in the immediate vicinity of the removal roller, and that the root circles of the teeth of the toothed rollers each affect a plane which is in or parallel below that of the tip circle of the removal roller tangent plane.
  • the planes affected by the root circles are at least around the tooth height of the toothed rollers below the plane affected by the tip circle of the removal roller.
  • the plane affected by the root circle of the rear tooth roller in the removal direction is lower than the plane affected by the root circle of the front tooth roller.
  • a retention force that is matched to the material is achieved in that the rear toothed roller is mounted so as to be adjustable with respect to the bale surface.
  • the fact that the rear toothed roller is adjustable around the center of the removal roller ensures that the distance of this toothed roller from the removal roller remains unchanged.
  • the tip circle of the rear toothed roller should be arranged particularly closely to the tip circle of the removal roller. The maximum distance between the two tip circles is 5 mm.
  • the removal of material residues lying on the floor is made possible in that the rear toothed roller is pivotally mounted and is pressed onto the bale by spring force.
  • the swiveling range of the toothed roller can expediently be limited by a stop.
  • the toothed rollers are driven at the driving speed of the removal device. This prevents fiber layers from being displaced by the toothed rollers.
  • the teeth of the toothed rollers are directed counter to the direction of rotation of the rollers. A hold-down or retention force constantly acting on the bale surface results from the fact that the set of toothed rollers consists of toothed disks with teeth offset in the axial direction.
  • the removal roller 1 and the tooth rollers 2 and 3 arranged in front of and behind it in the removal direction according to arrow P are in holders 10; 20 and 30 rotatably mounted, which are attached to a carriage 4.
  • the carriage 4 is arranged in a manner not shown in a mobile machine frame and can be moved up and down in vertical guides in order to bring the removal roller 1 and the tooth rollers 2 and 3 into and out of engagement with the surface of the bale to be processed (not shown).
  • the carriage 4 is driven in the vertical direction by chains 41.
  • the rollers can also be mounted in a boom of known type which is arranged on a movable tower and can be moved in the vertical direction.
  • the removal roller 1 is equipped with teeth 11 inclined in the direction of rotation and is driven counterclockwise in the direction of the arrow P 1.
  • the drive takes place by means of a belt 12.
  • the toothed rollers 2 and 3 are driven in the same direction, their drive taking place at the driving speed of the device in the removal direction P.
  • the set of toothed rollers 2 and 3 consists of toothed disks 22 and 32, the teeth 21 and 31 of which are offset from one another in the axial direction and are directed against the direction of rotation of the toothed rollers 2 and 3.
  • the toothed rollers 2 and 3 are arranged in the immediate vicinity of the removal roller 1.
  • the tip circle S3 of the rear toothed roller 3 should be arranged closely to the tip circle S1 of the removal roller 1. It can be provided that the tip circle S3 of the toothed roller 3 overlaps with the tip circle S1 of the removal roller, or has a distance from it that does not exceed 5 mm.
  • the toothed rollers 2 and 3 are arranged with respect to the removal roller 1 such that the root circle F2, F3 of the teeth 21 and 31 of the toothed rollers 2 and 3 affects a plane E2 or E3, which is in or below that of the tip circle S1 the teeth 11 of the removal roller tangent plane E1.
  • the levels E2 and E3 are at least about the height of a tooth 21 or 31 of the toothed rollers below the level E1. Since the toothed roller 3 arranged in the removal direction behind the removal roller 1 is particularly important for good retention and retention of the fiber material when it is removed from the bale surface by the removal roller 1, it is provided that this roller engages deeper into the bale surface than the toothed roller 2.
  • the level E3, which is affected by the root circle F3 of the rear toothed roller 3, is consequently lower than the level E2, which is affected by the root circle F2 of the front toothed roller 2.
  • the toothed roller 3 is in relation to the bale surface adjustable in a longitudinal slot 5.
  • the toothed roller can thus be lowered in the case of softly pressed bales, as a result of which it presses the fiber material downwards and thus prevents larger pieces from being torn up.
  • the longitudinal slot 5 preferably runs along a circular arc wrapped around the center of the removal roller 1, so that when the toothed roller 3 is adjusted, its predetermined distance from the removal roller 1 is maintained.
  • the rear toothed roller 3 is attached at both ends to arms 6 which are pivotally mounted in the machine frame.
  • the arms 6 are mounted on the axis of the removal roller 1 and pivotable about them, so that here too the toothed roller 3 maintains its predetermined distance from the tip circle S 1 of the removal roller 1 during a pivoting movement.
  • the toothed roller 3 is pressed against and into the surface of the bale by the force of a spring acting on the free end of the arms 6, in the present case a rubber spring 61.
  • the holder 62 attached to the slide 4 for the rubber spring 61 also serves as a stop for an adjusting screw 7 attached to the arms 6. This stop limits the swiveling range of the arms 6 downwards towards the bales. By turning the nut 71 of the adjusting screw 7, the swivel range can be set to a desired dimension.
  • the arrangement of the toothed roller 3 according to FIG. 2 has the advantage that the plane of engagement of the toothed roller in the bale changes automatically according to the strength of the bale pressure. With soft pressed bales or fiber layers there is a greater compression than with hard pressed material, so that in any case the material is held down securely and larger pieces are prevented from being pulled up.
  • the pivotable arrangement of the toothed roller 3 also enables the last material layer lying on the floor to be easily removed, since this is also held down securely by the toothed roller 3 and cannot slide away.
