Disclosed are various embodiments for robotic item sortation and optimization along the vertical axis in a conveyor-based system. A robotic system may be mounted above or adjacent to a conveyor system that moves items along a conveyor belt or similar device. Once an item is laterally diverted from the conveyor system, the robotic system may collect the item at a respective holding station and move the item along a vertical axis for placement in one of a plurality of vertically-configured item handling devices.

Device for conveying piece goods along a conveying path includes a sorting device for sorting piece goods, track profile members extending transversely to a track conveying direction and connected together to form an endless conveyor track with an upper and a lower run. The upper run has a conveyor surface for conveying the piece goods in the track conveying direction. Push shoes are successive along the conveying path and each is displaceable along at least one track profile member of the track profile members so as to constrainedly displace the piece goods laterally on the conveyor surface transversely to the track conveying direction of the endless conveyor track. A drive drives the endless conveyor track in the track conveying direction. Each push shoe includes a guide roller, which is arranged below the upper run and mounted to be rotatable about an axis of rotation extending transversely to the conveyor surface.

An article sortation system and method of sorting articles includes an article sorter having an article support surface moving in a longitudinal direction and a plurality of discharge conveyors extending from the article support surface. The sorter is adapted to discharge articles from the article support surface to said discharge conveyors. One or more of the discharge conveyors includes an active aligner having a driven surface that is adapted to reorient at least some of the diverted articles.

A material handling system includes a very high speed linear sortation conveyor that receives articles at an operating speed of 650 to 700 feet per second (fps) and up to 100 fps with gapping as small as one inch. In one or more embodiments, a recirculation sortation conveyor receives articles that are not diverted by the linear sortation conveyor with dynamic capacity sufficient to handle a high speed shutdown of the linear sortation conveyor. The recirculation sortation conveyor is itself a very high speed linear sortation conveyor having a pusher pre-sort feature that can distribute received articles at different lateral positions on an endless conveyor to align with more than one recirculation sortation conveyors that may be operating at a slower operating speed. In an exemplary embodiment, the recirculation sortation conveyor has a divert section for diverting articles to a divert target on a lateral side.

A roller shoe slat sorter conveyor system includes a conveyor forming an upwardly facing support surface. The support surface includes slots oriented transversely to the conveying direction and a plurality of roller shoe assemblies mounted for sliding movement along respective slots for transversely discharging objects from a medial position to either side of the conveying surface. Each roller shoe assembly includes a releasably mounted carrier disposed below the conveying surface. The releasable connection enables the roller shoe to detach from the carrier, and be manually reattached. The elongated roller shoe features downward slanting ends and includes a plurality of roller wheels extending above the surface of the shoe mounted to axles movable in a vertical axis whereby an article resting on the rollers of a shoe depresses the rollers so they contact the slat surface and move an article resting thereon at twice the speed of the shoe.

A sortation conveyor includes a pair of conveying members defining a conveying surface extending in a longitudinal direction. The sortation conveyor also includes an end cap fixedly secured to respective ends of the conveying members. The sortation conveyor further includes a pusher element selectively moveable across the conveying surface. The pusher element is releasably coupled to at least one of the conveying members or the end cap.

A conveyor system with a pop-up transfer assembly for transferring articles off the end of conveyor belt having protrusions extending above the belt's outer conveying surface. The transfer assembly is cantilevered over the reversing path of the conveyor belt from a pivot. When a protrusion from the belt hits the transfer assembly, the transfer assembly pivots away from the belt about the pivot. When the protrusion is clear, the transfer assembly drops, by gravity, back to its home position proximate the belt. A bilateral transfer assembly is cantilevered in opposite directions to transfer articles off the end of one conveyor belt onto another conveyor belt that may or may not have protrusions. The transfer assembly can have powered driving surfaces to aid the transfer of articles.

A plurality of diverters each selectively divert at least one article moving member having a diverting member from a non-diverting path extending longitudinally along said sorter to a diverting rails in a diverting state. At least one of the diverters has a gate having a diverting surface. The gate is selectively rotatable between the diverting state and a non-diverting state about a generally horizontal axis. An actuator moves the gate between the non-diverting state and the diverting state. The actuator is an electrically operated rotary actuator that is rotatable about another generally horizontal axis of rotation.

System for sorting products comprising a number of combinations of an elongated carrying body and a pusher body, located one after another, which combinations are movable in a direction of movement following a path along which a number of sorting locations are provided, wherein the carrying bodies extend parallel to each other and perpendicular to the direction of movement and wherein the carrying bodies are configured for carrying the products to be sorted, a displacing device for moving the combinations in the direction of movement along the path, wherein each combination is further provided with a further displacing device comprising an electric motor for moving the pusher body in a sorting direction along the carrying body, the sorting direction extending perpendicularly to the direction of movement, for pushing a product carried by the carrying body off of the carrying body with the pusher body, and, amongst other, a plurality of controllers.
