Definitions

  • the invention relates to a method for shredding chips in a shredding room between a driven, rotatable in both directions, with shear elements, horizontal shaft and associated counter shear elements, with chips entered from above crushed and discharged down over a perforated screen bottom and blocking Components that cause a shaft standstill are discarded after reversing the shaft become.
  • the invention further relates to two devices for performing the inventive method.
  • EP 0 717 663 B1 describes a vertical chip breaker for steel or metal chips with a Coarse part ejection element known.
  • This single-shaft crusher consists of a receiving funnel and a grinding funnel adjoining at the bottom with a circumferentially distributed arrangement Rice blocks, on the edges of which are attached to a rotating cutter head Rice knives are movable past.
  • a grinder connects below the grinding funnel. In the lower area of the grinding funnel one is closed by means of a power-driven channel slide opening chute provided for coarse parts. If there is a large part between the Chip material is located, then this lies on the grinder and is from the cutter head rotated together with the chips until there was a blockage of the Knife head comes.
  • a slow reversal process is used to remove the blockage initiated and the large part ejection element opened, so that the interference elements from the cutter head can be transported to and through the ejection.
  • a disadvantage of this design is that it cannot be used for horizontal chip breakers.
  • the rotary movement of the cutter head is impaired, distinguish between dense tufts of chips and coarse parts or combinations of the two.
  • dense tufts of chips often lead to a blockage can. These tufts are also removed here via the ejection and thus the Shredding process withdrawn.
  • the object of the above invention is now a method and two To provide devices of the type mentioned in the introduction, wherein a Horizontal chip breaker is provided which divides the blocking components into groups, e.g. dense tufts of chips, pure coarse parts, differentiates and each group a defined Reversing process and, if necessary, a discharge from the comminution area via a Assigns coarse part ejection element.
  • groups e.g. dense tufts of chips, pure coarse parts
  • a method is provided in which the Speed of change in the load of the driven, loaded with shear elements Wave is detected., Due to the detected speed of change in load taking into account the type, amount, and / or size of chip, the presence of blocking Components is determined and then the non-crushed blocking components ejected after one or more reversals of the shaft.
  • the shredding process is after Removal continued again.
  • the method according to the invention can advantageously be carried out such that Detection of the speed of change in the load of the driven, with Shear-occupied shaft, the acceleration of the shaft is detected.
  • Hard, one-piece Coarse parts e.g. Fragments of machined workpieces produce a high negative Acceleration.
  • Very dense tufts of chips cause a lower negative acceleration.
  • the value is even lower.
  • the Rate of change of load also e.g. about the change in torque of the shaft are measured using strain gauges. This would depend on the load the speed of the shaft deformation vary. Also are vibration meters conceivable, because a blockage by coarse parts would cause a higher vibration than dense tufts of chips.
  • the method according to the invention can be carried out such that on the basis of the determined Acceleration profile, the components causing a blockage in at least two Categories are divided, the components depending on the applicable category more or less frequently moved by reversing the shaft and either crushed or continued to be thrown back uncrushed.
  • Subdivision into categories allows for blocking components for each component type to design an optimized program flow. This is how compacted tufts of chips become, one Cause blocking due to the relatively low negative effects it causes Acceleration recognized as such. There may be a long period of repeated reversing Follow closed coarse part ejection element, whereby the compacted bundle of chips shreds shall be. At the end of the reversing process, dense remnants of clumps can still be present the large part ejection element to be opened are discharged. Form another category blocking coarse parts. Rough parts can e.g. Fractions of machined workpieces or screws. These coarse parts abruptly cause a high negative in the event of a blockage Acceleration. Since such components are not crushed by the shear elements is possible, a short reversing process with the coarse part ejection element open initiated to eject the bulk as quickly as possible.
  • the method according to the invention can advantageously also be carried out in such a way that Detection of a negative shaft acceleration measured the change in speed of the drive becomes.

  • a detection on the shaft would be to implement only with great effort. For example, would need a sensor to prevent contamination from adhering or chip dusts penetrating into the housing are protected.
  • An optical sensor would be not to be used due to the chips to be shredded.
  • the inventive method can also be carried out so that during the Reversing the shaft's rotational speed is lower than the normal rotational speed is set. Lowering the speed when reversing prevents blocking components are abruptly loosened and flung around in the shredding room. Instead, the blocking component must be loosened carefully and reversed over to carry the shaft away to the coarse part ejection element.
