Conveyors are used when material is to be moved frequently between specific points over a fixed path and when there is a sufficient flow quantity to justify the fixed conveyor expenditure.[4] Various kinds of conveyors can be characterized by the type of product being managed: unit load or bulk load; the conveyor’s area: in-floor, on-floor, or overhead, and whether loads can accumulate on the conveyor. Accumulation allows intermittent movement of each unit of materials transported along the conveyor, while all systems move concurrently on conveyors without accumulation capability.[5] For example, while both the roller and flat-belt are unit-load planetary gearbox on-floor conveyors, the roller provides accumulation capability while the flat-belt does not; similarly, both power-and-free of charge and trolley are unit-load overhead conveyors, with the power-and-free made to include a supplementary track in order to supply the accumulation capability lacking in the trolley conveyor. Examples of bulk-handling conveyors include the magnetic-belt, troughed-belt, bucket, and screw conveyors. A sortation conveyor system is utilized for merging, identifying, inducting, and separating items to become conveyed to specific destinations, and typically consists of flat-belt, roller, and chute conveyor segments together with various moveable arms and/or pop-up wheels and chains that deflect, push, or pull products to different destinations.[6]
