A First In, First Out (FIFO) conveyor system is a technique used for product storage in factories or warehouses. It allows goods to be stored and moved in the order they arrive, ensuring the first product in is the first product out. This system typically uses gravity or driven roller conveyors to store and convey large quantities of manufacturing goods. Products like pallets or totes are inserted at the infeed end and conveyed to the outfeed end, making it a straight-through storage method. Depending on the product size, weight, and fragility, this process can be powered or gravity-based.
