Patent ID: 8607963

Claim:
A conveyor installation comprising carrier bags ( 1 , 1 a , 1 b ) for material ( 7 , 7 a ) to be transported, the conveyor installation comprising a stationary transport rail ( 41 ) comprising carrier dogs ( 44 ) for receiving in each case one carrier bag ( 1 , 1 a , 1 b ), the carrier dogs ( 44 ) being movable in a transport direction ( 42 ), wherein each carrier bag ( 1 , 1 a , 1 b ) comprises in each case one sack ( 15 ) for receiving material ( 7 , 7 a ) to be transported; wherein each sack ( 15 ) comprises a bottom ( 2 ), a front wall ( 4 ) having a width a and a rear wall ( 3 ) having a width a and side walls ( 5 , 6 ) having a width b which is narrow relative to the width a of the front wall ( 4 ) and of the rear wall ( 3 ); wherein each sack ( 15 ) comprises a support frame ( 33 ) which encloses an upper loading opening ( 34 ) of the sack ( 15 ); comprises a suspension point ( 23 ) at an upper end, the suspension point ( 23 ) being adapted to be inserted into a carrier dog ( 44 ); and comprises a pressure piece ( 29 ) which is parallel to the front wall ( 4 ) and to the rear wall ( 3 ); a loading station (B) which comprises a sliding surface ( 54 ) which is arranged below and parallel to the transport rail ( 41 ); and a coupling (K) formed between a carrier dog ( 44 ) and the support frame ( 33 ) carried by the carrier dog ( 44 ), which coupling (K) in a position in which the pressure piece ( 29 ) is disengaged from the sliding surface ( 54 ), takes up a first rotational position of the carrier bag ( 1 , 1 a , 1 b ) relative to the carrier dog ( 44 ) in which rotational position the loading opening ( 34 ) of the carrier bag ( 1 , 1 a , 1 b ) takes up a position which is transverse to the transport direction ( 42 ); and when the pressure piece ( 29 ) is in contact with the sliding surface ( 54 ), takes up a second rotational position of the carrier bag ( 1 , 1 a , 1 b ) relative to the carrier dog ( 44 ) in which rotational position the loading opening ( 34 ) of the carrier bag ( 1 , 1 a , 1 b ) is parallel to the transport direction ( 42 ).
