An unpacking system for use in an apparatus for producing three-dimensional work pieces by irradiating layers of a raw material powder electromagnetic or particle radiation comprises a supporting structure which is configured to support a building chamber arrangement. The building chamber arrangement comprises a building chamber accommodating a carrier, the carrier being configured to receive a three-dimensional work piece produced from a raw material powder by an additive layering process. A lowering mechanism of the unpacking system is configured to apply a driving force to the building chamber so as to lower the building chamber relative to the carrier until a three-dimensional work piece received on the carrier can be removed from the carrier.

The invention relates to an assembly comprising an unmanned transport device for delivering a shipment and a transfer device, said transfer device being designed to lower the shipment from the unmanned transport device to a receiving container, to lift the shipment from the receiving container to the transport device and/or to transfer said shipment between the transport device and the receiving container, the shipment being guided in each case by the transfer device.

Technologies are described for restraining systems. The systems may comprise a base, a stationary arm, a swing arm, a rod, first straps, and second straps. A bottom end of the stationary arm may be attached to a first end of the base. A bottom end of the swing arm may be attached at a second end of the base. The rod may be attached to top ends of the stationary arm and the swing arm. First straps may be attached to the stationary arm and configured to loop around and support an object. Second straps may be attached to the swing arm and configured to loop around and support the object. The rod may move and push the top of the swing arm away from the top of the stationary arm. A friction force between the first and second straps and the object may be effective to restrain the object.

A vertical reciprocating conveyor that can be transported in a storage condition and assembled at a work facility in an operating condition. The vertical reciprocating conveyor includes a carriage assembly that is movable along a pair of spaced vertical rails of a support frame. The carriage assembly includes a pair of spaced uprights and a carriage deck designed to support material moved along the pair of spaced vertical rails of the support frame. The carriage deck is movable between an operating condition and a storage condition, where the carriage deck is perpendicular to the pair of spaced uprights in the operating condition and parallel to the pair of spaced uprights in the storage condition. The movement of the carriage deck allows the overall size of the vertical reciprocating conveyor to be reduced for shipping.

A removable display hoist includes a first clamp configured to be removably coupled to a first portion of a telescoping support member, a second clamp configured to be removably coupled to a second portion of the telescoping support member, and an actuator assembly coupled between the first clamp and the second clamp, where the actuator assembly is configured to extend and retract the removable display hoist.

Device for lifting an article from a roller conveyor having a fork that can be raised and lowered, and having a plurality of spaced-apart elongate tines which, in the lowered position, move with the tines between or below the rollers of the roller conveyor in order to lift one or a plurality of articles from the rollers as the fork is being raised into the raised position with the tines, where the tines form a carrier surface for the article and the tines can be expanded in the direction transverse to the longitudinal extension thereof in order to form an expanded carrier surface.

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.
