Abstract

The contents of successive containers for comminuted tobacco leaves are transferred onto or into a receiver (such as a belt conveyor) at a transfer station where an indexible upright manipulator carries a lifter and an evacuating device including a tilting unit. Successive containers, delivered to the transfer station by a roller conveyor or the like, are lifted by the lifter off the conveyor and the manipulator is thereupon indexed to deliver the lifted container to a location above the receiver. The tilting unit is thereupon caused to tilt the container to thus transfer, by gravity flow, the contents of the container onto an openable intercepting device at a level between the tilter and the receiver. The intercepting device is thereupon opened to permit the intercepted material to descend onto or into the receiver. The manipulator is thereupon indexed to move the emptied container to a position above a further conveyor serving to transport empty containers away from the transfer station. The multi-stage transfer of particulate material from a container above the receiver onto or into the receiver reduces the generation of dust and the likelihood of undesirable comminution of such material.
