An apparatus for unloading material. The apparatus comprises a hooking device mounted on a frame for hooking the material. The hooking device comprises a plurality of rows of curved hooks, each row of hooks being pivotable about a respective axis of rotation between a non-operating position, in which the hooks are retracted, and an operating position, in which the hooks are extended so as to hook the material. All the rows of hooks are pivotable from the non-operating position into the operating position along a hooking path, rotating in the same direction of rotation about the respective axes of rotation. The hooking device further comprises an abutment element that is positioned on the outside of the rows of hooks, substantially perpendicularly to the hooking path.

Systems and methods to manipulate stacks of silicon wafers and rings are described. In one aspect, a robotic actuator includes a robotic end effector that further a first surface having multiple attached wafer suction cups arranged to collectively grasp a silicon wafer. The robotic end effector also includes a second surface that further includes multiple attached ring suction cups arranged to collectively grasp a ring. The second surface also includes a bulk grabber positionable to grasp a collective stack of rings. The robotic actuator also includes an axial actuator configured to rotate the robotic end effector about a flip axis, such that either the first surface or the second surface faces vertically upwards.

Warehouse automation and methods of handling materials can be used to enhance the safety and efficiencies of warehouse operations. For example, automation systems and methods that make depalletization processes safer and more efficient are described. In some examples, a rotary lift table is used to automatically position a pallet load of boxes in an ergonomic position where a worker can readily transfer the boxes from the pallet to another location, such as a conveyor or another pallet. In some examples, a work cell for a worker includes two of the rotary lift tables that function in that manner.

A control apparatus includes a first information acquiring section that acquires three-dimensional information of a first region of surfaces of a plurality of objects, the information being obtained by imaging or scanning the plurality of objects from a first location; a second information acquiring section that acquires three-dimensional information of a second region of surfaces of the plurality of objects, the information being obtained by imaging or scanning the plurality of objects from a second location; and a combining section that generates information indicating three-dimensional shapes of at least a portion of the surfaces of the plurality of objects, based on the three-dimensional information of the first region acquired by the first information acquiring section and the three-dimensional information of the second region acquired by the second information acquiring section.

An automated storage and retrieval system includes a storage array of storage locations for case units. An in-out case conveyor is capable of bi-directionally transporting case units to and from the storage array, and an in-out loaded pallet conveyor is capable of bi-directionally transporting loaded pallets towards and away from the storage array. A palletizer-depalletizer cell includes a bi-directional pallet transport system with more than one independently driven pallet transports, each with a different pallet holder independently movable relative to a cell frame. Placement of case units commissioning a pallet layer loading a pallet, and removal of case units decommissioning a pallet layer unloading another pallet are both effected at the common pallet layer interface at a predetermined level of the cell frame. The pallet transports independently index a first and a second of the different pallet holders, each independently holding the pallet loading at the common pallet layer interface.

A storage system and a load handling device for lifting and moving containers stacked in the storage system are described. The storage system includes a plurality of rails or tracks arranged in a grid pattern above the stacks of containers. The grid pattern can include a plurality of grid spaces and each stack is located within a footprint of only a single grid space. The load handling device is configured to move laterally on the rails or tracks above the stacks. The load-handling device includes a container-receiving space located above the rails or tracks in use and a lifting device arranged to lift a container from a stack into the container-receiving space. The load handling device has a footprint that, in use, occupies only a single grid space in the storage system.

A vision-assisted robotized depalletizer receives at a pallet station a pallet loaded with products and outputs on a conveyor unitized products aligned in a desired orientation. Such depalletizers include a vision system having one or more image acquisition sensors that are positioned relative to the pallet station so as to have a field of view covering a top portion of the pallet. The sensors send to a controller one or more image of the top portion of the pallet that the controller uses along to determine the position of each product in the top portion of the pallet. The depalletizer further includes a robot equipped with a depalletizing tool that is coupled to the vision system controller for receiving information indicative of the position of each product from the top portion and uses that information to pick and position on the output conveyor each product from the top portion.
