Definitions

  • the invention concerns a method and a device in the handling of recycling packages, such as bottles and cans.
  • both recycling cans and recycling bottles are received.
  • the recycling cans are passed to a crusher device of their own, preferably a press, which presses the can into smaller volume.
  • the plastic bottles are passed to a crusher device of their own, which presses the plastic bottles into smaller volume.
  • the recycling packages that have been brought into smaller volume are transferred further into gathering storage.
  • the return automat that receives recycling packages, preferably plastic bottles and cans, comprises a frame construction and, in connection with its front panel, a receiving opening, into which the recycling package, such as a bottle or a can, is placed.

In such a case, the device does not transfer the recycling package further. In this way, the processing of full packages is eliminated.
  • a photocell detects a recycling package in the lifting position.
  • a light curtain is placed at the mouth of the receiving space A.
  • the recycling package is transferred upwards by means of a tray part passing through an opening in the bottom plate.
