Claim:
A device for removing two covers ( 11 , 12 ) from a storage box ( 13 ), comprising a transport device ( 17 ) transporting the storage boxes ( 13 ) with space between each one and along a path, and at least one roller station ( 18 ) with two suction devices ( 19 , 24 ) which lift and securely hold the two covers ( 11 , 12 ) using suction force, and two rollers ( 20 , 21 ) which roll up the securely-held covers ( 11 , 12 ) and are located one behind the other, with space between them, in the transport direction, with associated drives ( 22 , 23 ), each of which includes a separate, controllable suction device ( 19 , 24 ), said suction device ( 19 , 24 ) on each roller ( 20 , 21 ) includes suction devices ( 19 ), with suction openings which are in at least one row with the roller and are connected to a vacuum source, at least one heating device ( 30 ) is located above a track, via which first one of the covers ( 11 ), sealed on the particular storage box ( 13 ) at the edge, is acted upon with radiant heat—as the storage boxes ( 13 ) pass through—in the region of a few of the sealed edges ( 15 ), in particular transverse edges, to reduce an adhesive strength and therefore to reduce resistance to separation by peeling, wherein a first one of the rollers ( 20 ) is designed with a suction device ( 19 ) for removing and rolling up the first top, sealed-on cover ( 11 ) and is located as the first roller ( 20 ) upstream of a second one of the rollers, as viewed in the transport direction, and a second roller ( 21 ) is designed with a suction device ( 24 ) for the subsequent removal and rolling up of a second cover ( 12 ) which is placed loosely in the storage box ( 13 ), and both rollers ( 20 , 21 ) rotate in the same direction of rotation for rolling up, and wherein the heating device ( 30 ) is located upstream of the roller station ( 18 ), as viewed in the transport direction wherein the roller station ( 18 ), the cover ( 11 , 12 ) and the drive ( 22 , 23 ) are configured so that after the cover ( 11 , 12 ) is rolled up, the roller station ( 18 ), together with the rollers ( 20 , 21 ), is swiveled away from the region of the track and the storage boxes ( 13 ), by approximately 90°, into a discard position and over a discard opening ( 33 ), at least one roller ( 20 , 21 ) is driveable in the discard position using the particular associated drive ( 22 , 23 ) in a direction opposite to the rolling-up position and, when the particular suction device ( 19 , 24 ) is turned off, discards the particular rolled-up cover ( 11 , 12 ) by unrolling it into the discard opening ( 33 ), and after the covers ( 11 , 12 ) are discarded, the roller station ( 18 ) is swiveled out of the discard position and back into its starting position.
