A drum loading and unloading system and method for loading and unloading a drum. The system includes a portable base unit having pedestals for holding a drum at a predetermined position for loading and unloading material from the drum; a pair of pneumatic cylinders attached to the portable base supporting a cross-beam; a pumping piston attached to the cross-beam for pumping material into and out of the drum; and a lifting device attached to the cross-beam for lifting the drum onto the pedestals of the portable base.

A method of manipulating boxes includes receiving a minimum box size for a plurality of boxes varying in size located in a walled container. The method also includes dividing a grip area of a gripper into a plurality of zones. The method further includes locating a set of candidate boxes based on an image from a visual sensor. For each zone, the method additionally includes, determining an overlap of a respective zone with one or more neighboring boxes to the set of candidate boxes. The method also includes determining a grasp pose for a target candidate box that avoids one or more walls of the walled container. The method further includes executing the grasp pose to lift the target candidate box by the gripper where the gripper activates each zone of the plurality of zones that does not overlap a respective neighboring box to the target candidate box.

A loading and unloading equipment that includes at least one carrier that essentially runs parallel to the ground, at least one supporting body extending diagonally or at an angle towards the carrier, at least one carriage body that is installed on the carrier, at least one motor that moves the carriage body in a direction of movement along the carrier, at least one loading and unloading device that may be or is set on the carriage body, at least one control device that at least controls the movement of the motor and/or the loading and unloading device, and at least one access device that consists of at least one stair-like or step-like walk-on element, and at least one locking tool, which blocks the access to the walk-on element when set to a locking position and which allows access to the walk-on element when set to a release position.

A method unloads bulk goods from a laterally open large container using an unloading device with a tilting unit and a platform. The tilting unit and the platform have a common rotational axis. Both the bulk goods and the unloading device are prevented from being damaged. The laterally open large container which is filled with a bulk good is positioned on the tilting unit. The platform is flipped up such that the platform closes the opening side of the large container. The tilting unit is tilted together with the large container located thereon and the platform closing the opening side of the large container about the common rotational axis such that the large container is positioned on the container opening side, and the bulk good is deposited on the platform. The tilting unit is then tilted back together with the large container, the bulk good remaining on the platform.

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.
