A stacker includes a base having a dolly-receiving area into which a dolly can be rolled. A vertical structure extends upward from the base. A pair of arms are pivotable toward and away from one another and toward and away from an area above the dolly-receiving area. The pair of arms are movable vertically relative to the vertical structure and are configured to engage containers supported on a dolly in the dolly-receiving area. In an alternate stacker, the pair of arms may be configured to revolve about an axis generally parallel to the arms and spaced away from the arms. In this manner the arms can dump the contents from a bin engaged by the arms.

A part feeding apparatus includes a guide, a separator, and a lift mechanism. The guide is to guide stacked parts stacked in a height direction along a height of the part feeding apparatus. The separator is configured to pick up a bottommost part located at a bottom of the stacked parts in the height direction. The lift mechanism is configured to lift the stacked parts except for at least the bottommost part.

A lumber stacking machine has a stacking mechanism forming a stack of lumber from the bottom upwardly. The stacking mechanism includes a lift mechanism formed with a plurality of stacking fingers that lift a layer of lumber vertically above a conveyor. With the formation of a new layer of lumber, the stacking mechanism moves below the new layer with the stacking fingers retracting to pass by the new layer and resting the growing stack of lumber on top of the new layer, and then extending below the new layer to raise the entire stack to allow another new layer to be formed. Stops are provided to control the movement of the individual boards from the infeed station into the stacking station and also to control movement of the new layer beyond the stacking station. Two conveyors cooperate to move the lumber with an overlap in the stacking station.

The invention relates to a holding device (1) for a container stack (200) which is stored and removed from below and to a storage system (100) for container stacks (200) which are stored and removed from below. The holding device (1) for a container stack (200) which is stored and removed from below has a holding hook (2) which comprises a support arm (3) that can be pivoted about a pivot axis (5) between a holding position for holding a container stack (200) and a removal position for removing a container (201) of the container stack (200). The holding device also has a trigger arm (4) which is rotationally fixed relative to the support arm (3). An instability balancing position is provided between the holding position and the removal position. The holding device (1) further comprises a restoring element (7) which is designed to push the support arm (3) to the holding position or to push the support arm (3) to the removal position when the support arm (3) is being pivoted.

A dispensing device that comprises vertical guidings for receiving a stack of a plurality of trays, a separating device for dispensing individual trays in a downward direction and a tray discharge device that has multiple rotating lifting elements. The dispensing device includes lifting elements that are formed cylindrically and have a comb structure with at least two immersing protrusions that extend in parallel to one another.

A method for dispensing pallets, comprising: moving a pallet stack held in a movable frame from a pallet-storage position to a pallet-dispensation position including: raising the pallet stack held in the movable frame, the movable frame being configured to be moved between the pallet-storage position and the pallet-dispensation position once the pallet stack is raised; and dispensing a pallet from the movable frame.

A device for receiving, stacking, and removing microplates is presented and described. The device comprises a tower for stacking the microplates, wherein a microplate comprises a container and, optionally, a lid. There is a retaining device at the lower end of the tower, which has a first retaining tool and a second retaining tool, and preferably partially encompasses a microplate. The first retaining tool is designed to hold a microplate in a form-fitting manner. The second retaining tool is designed to fix a container in the microplate in place in a frictional manner. The first retaining tool is above the second retaining tool in the stacking direction. A system that comprises the device described above, a dispenser device, and a transport device, is also disclosed. The dispenser device is used to fill microplates, and the transport device is used to add and remove microplates to and from the device.

A separating system (1) comprises a housing (60) sized to receive a stack of articles having at least one first article (12) stacked on top of a second article (10). The system (1) also includes a lifter (20) movable into a contact position adjacent a surface (13) on the at least one first article (12). The lifter (20) is adapted to apply a lifting force to the surface (13) to lift at least a portion of the first article (12) above the contact position. An extractor (40) moves the second article (10) away from the stack of articles after the at least one first article (12) has been lifted above the contact position by the lifter (20). The housing (60) prevents the at least one first article (12) from moving with the second article (10) when the second article (10) is moved by the extractor (40) and guides the stack of articles downward after the second article (10) is moved away.

Exemplary systems and methods are disclosed for stacking containers in an automated storage and retrieval system. The system includes a plurality of storage stacks establishing a grid of storage locations and a plurality of buffering stacks. Each buffering stack having a hand-over location for holding containers near a surface of a grid and at least one intermediate holding location for holding the containers to be transported to processing stations or storage locations within the grid. An overhead load handler is configured to lift or lower containers from/to the top of a storage stack or the hand-over location of a buffering stack.

A storage facility for the storage of stackable goods, especially stackable postal item containers, includes at least one storage device and at least one stacking device. The at least one storage device includes storage locations. At least one of the storage locations is configured to receive at least two items of goods stacked on top of one another. A mechanism is configured to move the at least one storage location and/or a further storage location within the storage facility, and the at least one stacking device is configured to stack one or more of the items of goods into the at least one storage location from below and/or unstack one or more of the items of goods from the at least one storage location from below. A method for storing stackable goods, especially stackable postal item containers, is also provided.
