7.11 Roller conveyor
Roller conveyors are multi-purpose conveyors for the transport of small unit loads like for example
tanks, cardboard boxes, boxes and packages, and greater material to be conveyed, e. g. pallets and
containers. They are suitable for transport, buffering (accumulating roller conveyors), and in con-
nection with supplementary devices for the distribution of piece goods. The load is transported by
means of transport rolls, which are interconnected by a chain, belt, or strap. Like belt conveyors, roll-
er conveyors can be designed with an end drive or centre drive in the form of a geared motor. Alter-
natively there is the possibility of directly actuating individual rolls via a tubular roller motor, in the
case of which the motor is directly integrated within the roll.
