Definitions

  • the invention relates to a roller cutting machine according to the preamble of claim 1.
  • a roller cutting machine is known for example from DE-B-1 507 485.
  • the rollers pull the waste to be shredded into the roller gap, where they shred it in mutual interaction. If there is a limit load, the rollers are automatically stopped and temporarily reversed, after which they are rotated again in the original direction. If the limit load is reached again, this reversing process is repeated or the machine is switched off. If the condition remains unsolvable, the funnel must be emptied upwards when the machine is shut down, which is naturally tedious, time-consuming and expensive. Such a machine can therefore only be operated under constant supervision if you want to avoid long downtimes.
  • the invention has for its object to remedy this and other disadvantages in an economically advantageous manner.
  • rollers run on their top side from the roller gap to the hopper walls enables them to loosen and tear up the waste, whereas previous machines were more likely to compact the waste in the roller gap, which reduced the cutting performance.
  • the funnel teeth are brought into the rest position, i.e. removed from the roller.
  • the material that cannot be cut can pass downwards past the roller and past the funnel wall and the funnel teeth can return to their starting position.
  • the funnel cannot become blocked and never needs to be emptied from above in an emergency. You can therefore load the funnel directly with large quantities of bulky waste, whereas until now it was only possible to add small portions that could also be removed upwards when blocked.
  • rollers are working away from each other, slowing down or a standstill of one roller does not necessarily affect the other roller.
  • Single drives can lead to practically complete independence of the rollers.
  • the rollers are so strongly linked to one another by the interlocking teeth and the material to be shredded that they inevitably always have to run or stand together.
  • each funnel wall area can be pivoted about a pivot axis that is axially parallel to the rollers, which axis is usually above the funnel teeth, because a large area can then be released and the funnel itself is virtually expanded.
  • a positive drive of the funnel teeth for their movement in the rest position and back in the working position has the advantage that the teeth can be held very rigidly in the working position and this rigid holder can only be released if necessary.
  • a hydraulic drive can serve very well, the pressure change can serve to trigger the rest position movement.
  • the triggering of the rest position movement of the funnel teeth can also be derived from the operating pressure of the roller drive alone or together with the operating pressure of the funnel tooth drive.
  • one row of funnel teeth can be moved in the rest position without affecting the other row, so that at least half the machine output is retained.
  • ring grooves are provided between the ring zones (which extend close to the relevant funnel teeth) on which the roller teeth are arranged, which are each dimensioned significantly retreating from the opposite funnel tooth.
  • no uncut material can still fall through because the tooth-bearing ring zones come very close to the funnel teeth.
  • An offset of the roller teeth in the circumferential direction increases the cutting performance in that only a part or even one of the roller teeth has a cutting effect.
  • roller teeth In the machine according to the invention, no cutting takes place in the roller gap, which is why there is no need for the roller teeth to interlock.
  • roller teeth it is advantageous if the roller teeth only reach just up to the roller gap, because this promotes their loosening effect when the waste is torn apart and allows the funnel cross-section to be maximized with the same roller dimension.
  • a hydraulic drive which operates with freewheels alternately driven by hydraulic units is considered to be particularly economical.
  • the invention is based on the pure schematic drawing of a machine according to the invention explained for example.
  • the machine 2 shown in FIGS. 1 and 2 has a hopper 2, in which two rollers 3 are arranged parallel to one another.
  • the funnel 2 has two funnel regions 20 which are parallel to the rollers 3 and which carry funnel teeth 21 at the lower edge.
  • Each of the hopper areas 20 can be pivoted about an axis 22 parallel to the rollers 3 by means of the associated hydraulic cylinder 23 from its working position (shown in FIG. 1 alone and in FIG. Right) to its rest position (shown in FIG. 2 on the left) and vice versa.
  • Each of the rollers 3 has teeth 30 which are offset in the circumferential direction, on ring zones 31 which are spaced apart in the axial direction, and annular grooves 32 lying in between.
  • the roller teeth 30 extend in the middle to the roller gap 33 and engage between the funnel teeth 21 when the funnel regions 20 are in the working position (shown in FIG. 1 alone and in FIG. 2 on the right). Then the ring zones 31 also reach close to the funnel teeth 21, whereas the ring grooves 32 are spaced apart from the funnel teeth 21 opposite them, so that clippings can fall off the funnel teeth.
  • Each roller 3 can be driven individually by its own hydraulic roller drive 4 (see FIGS. 1 and 3).
  • Each roller drive 4 has (see FIG. 3) two rectified freewheels 40, 41, each of which is operatively connected to a lever 42, 43.
  • One hydraulic cylinder 44, 45 is operatively connected to each lever 42, 43.
  • a controller 5 ensures that hydraulic cylinders 23, 44 and 45 are supplied with hydraulic oil from the pump device 50 in the correct position (cf. FIG. 1).
  • the funnel regions 20 are in the working position and the rollers 3 turn upwards from the roller gap 33 towards the funnel teeth 21.
  • the control device 5 which monitors the pressure in the hydraulic cylinders 44, 45, brings the hydraulic cylinders 23 of one or both funnel regions 20 into a return movement, as a result of which the relevant funnel region 20 or both funnel regions 20 swings away from the associated roller 3 in the rest position.
  • the pinched material can pass downwards, the pressure in the hydraulic cylinders 44, 45 of the roller drive 4 normalizes, and the controller 5 allows the hydraulic cylinders 23 to pivot the funnel area (s) in question into the working position.
  • a machine is drawn in which all the funnel teeth on one funnel side can be pivoted together with the funnel area. You can also make groups of teeth and individual funnel teeth pivotable on their own if this makes the type of material appear necessary.
