Abstract
A conveyor installation comprises carrier bags for material to be transported, wherein the carrier bags are suspended from carrier dogs which are moved in a transport rail in a transport direction. At a loading and unloading station, the carrier bags are rotatable from their transport position, which is transverse to the transport direction, into a position which points in the transport direction, wherein an upper loading opening is opened at the same time. Backwards rotation of the carrier bags is caused by the force of gravity.
Claims14
A conveyor installation comprising carrier bags (1, 1a, 1b) for material (7, 7a) 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, 1a, 1b), the carrier dogs (44) being movable in a transport direction (42),
- wherein each carrier bag (1, 1a, 1b) comprises in each case one sack (15) for receiving material (7, 7a) 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, 1a, 1b) relative to the carrier dog (44) in which rotational position the loading opening (34) of the carrier bag (1, 1a, 1b) 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, 1a, 1b) relative to the carrier dog (44) in which rotational position the loading opening (34) of the carrier bag (1, 1a, 1b) is parallel to the transport direction (42).
