DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a separating device for at least one item located in a housing part which is open on one side, partially over an opening in the housing part, in particular a tape reel in a housing part, comprising a gripping device for the item.
For the reprocessing of cassettes of any kind or the recycling of cassettes, it is necessary to separate at least one tape or film reel from at least one housing part in order either to use a new tape or film reel or to separate the plastic material of the housing from that of the tape or film material in order to carry out separate recycling.
DESCRIPTION OF THE RELATED ART
EP-A-639 406 describes a process and apparatuses for reprocessing magnetic tape cassettes. This discloses a separating device for at least one tape reel which separates the latter from a housing part which is open on one side and which device is also intended for transporting the items further by means of a detector device, connected to a movement-controlling means.
FR-A-2 534 705 discloses a device for opening a film cartridge and for removing the film from the cartridge, the film cartridge being fixed on the outer side by a holder and the film together with the reel being pressed out from the film cartridge by means of a ram.
EP-A-554 785 discloses for the recycling of used magnetic tape cassettes opening the cassette housing and removing the tape reels, in that the cassette housing is punched out or milled out around the tape reels and the winding hubs are punched out. In this case, there is no separation of housing material, reel material and tape material, with the result that material separation for recycling according to the particular material still has to take place subsequently.
DE-A-4 137 568 also discloses in the case of ink ribbon cartridges the suction removal of the ink ribbon remaining in the lower part of the cartridge once the cartridge has been destroyed, and separate recycling of said ribbon. Such suction removal is not technically appropriate for magnetic tape cassettes, where several hundred meters of tape are wound up, for reasons of time and with large amounts of tape.
It is therefore an object of the present invention to provide a separating device for items from housing parts, in particular tape or film reels, in which a cost-effective separation of the materials of the housing part and of the tape reels takes place.
SUMMARY OF THE INVENTION
We have found that this object is achieved according to the invention by a separating device of the type described at the beginning if the separating device includes a pushing-out device which comes up against the item through the opening in the housing and moves said item into the region of the gripping device, which separates the item from the housing part.
This achieves a quick separation of reels and housing part and, by means of the gripping device, a specifically directed transporting of the reels can be achieved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In practice, a covering is arranged on the gripping device behind the item in the direction of the pushing-out movement of the pushing-out device. As a result, a safe gripping operation is ensured and the tape reel cannot be pushed away.
The separating device is expediently provided with a detector device for the state of the item. As a result, for example in the case of tape reels, it can be established specifically and at an early time whether the tape reel is empty or still contains tape, and also of which type the tape or the film is. As a result, separating of the reels with and without tape is possible.
It is advantageous to use a sensing device, in particular a light sensing device, as the detector device.
In practice, this sensing device may be provided directly on the gripping device. As a result, the spatial assignment is achiev
