Loop sortation systems, or circle sorters, as they are also known, can be configured with tight radius curves to maximize space and conform to facility limitations. Looped sortation systems typically are comprised of a series of cells linked together on a track. Product is inducted onto these cells either manually or automatically at any place along the conveyor system. Product can be identified by either scanning it as it travels along the conveyor or associating it with a particular induction station, as is the case in many distribution systems. Once the cell and associated inventory arrive at a divert location, the divert mechanism on the loop sortation system is actuated, sending the inventory to the associated location. These sortation systems include:
