Conveyors are used when materials is usually to be moved frequently between particular points over a fixed path and when there is a sufficient flow volume to justify the fixed conveyor expense.[4] Various kinds of conveyors can be characterized by the kind of product being handled: unit load or mass load; the conveyor’s area: in-floor, on-ground, or overhead, and whether loads can accumulate on the conveyor. Accumulation enables intermittent movement of each unit of material transported along the conveyor, while all models move concurrently on conveyors without accumulation capability.[5] For instance, while both roller and flat-belt are unit-load on-floor conveyors, the roller provides accumulation capability as the flat-belt does not; similarly, both the power-and-totally free and trolley are unit-load overhead conveyors, with the power-and-free made to include a supplementary track in order to provide the accumulation capability lacking in the trolley conveyor. Examples of bulk-handling conveyors are the magnetic-belt, troughed-belt, bucket, and screw conveyors. A sortation conveyor program is utilized for merging, identifying, inducting, and separating products to be conveyed to specific planetary gearbox destinations, and typically consists of flat-belt, roller, and chute conveyor segments as well as various moveable hands and/or pop-up tires and chains that deflect, push, or pull products to different destinations.[6]
