Abstract:
A method for fetching a target bin stored in a storage system (100), wherein the storage system includes a three-dimensional storage grid containing a plurality of bins stacked in vertical stacks, supporting rails (13) on the grid structure, and a plurality of vehicles (1), controllably arranged to move individually on the supporting rails. The method is performed by a control device in the system and comprises controlling at least one non-target vehicle to operate as intermediate storage for a bin located vertically above the target bin (5); controlling a target vehicle to pick up the target bin, and controlling the at least one non-target vehicle and the target vehicle to be positioned adjacent to each other in a linear manner on the supporting rails. A corresponding storage system has also been disclosed.

The vehicle comprises driving means (5, 19) situated at or at least partly within rolling means (10, 11) of the vehicle, providing rolling set specific driving force to the vehicle in either the first direction (X) or the second direction (Y).
Abstract:
A storage system comprises a first grid structure of storage cells, each cell being arranged to accommodate a vertical stack of storage bins, the first grid structure having a top level (20), a first vehicle (40), arranged to move horizontally at the top level of the first grid structure, and to receive a storage bin from a storage cell at the top level of the first grid structure and to deliver the storage bin to a bin lift device (56), arranged to convey a bin between the top level (20) of the grid structure and a delivery station (66). The system further comprises a second grid structure of storage cells at a different vertical level than the first grid structure, and a second vehicle (42), arranged to move horizontally at the top level (22) of the second grid structure, and arranged to receive a storage bin from a storage cell at the top level of the second grid structure and to deliver the storage bin to the bin lift device.
Abstract:
The invention concerns a remotely operated vehicle assembly for picking up storage bins from a storage system and a method for change of vehicle direction. The vehicle assembly comprises a vehicle body displaying a cavity being suitable for receiving a storage bin stored within the storage system, a vehicle lifting device being connected at least indirectly to the vehicle body and suitable for lifting the storage bin into the cavity, a displacement arrangement comprising inter alia a displacement motor situated above the cavity which is configured to at least provide the power that is necessary in order to displace one or both of the first set of vehicle rolling means and the second set of vehicle rolling means between a displaced state where the relevant vehicle rolling means is displaced away from the underlying storage system during use, and a non-displaced state where the relevant vehicle rolling means is in contact with the underlying storage system during use, and driving means coupled to the displacement arrangement. The driving means further comprises a first set of vehicle rolling means connected to the vehicle body allowing movement of the vehicle along a first direction (X) within the storage system during use and a second set of vehicle rolling means connected to the vehicle body allowing movement of the vehicle along a second direction (Y) in the storage system during use, wherein the second direction (Y) is perpendicular to the first direction (X).
Abstract:
The invention concerns a remotely operated vehicle assembly for picking up storage bins from a storage system and a method for changing a power source arranged within the vehicle assembly. The remotely operated vehicle assembly comprises a vehicle body which displays a cavity for receiving a storage bin situated somewhere within the storage system, a vehicle lifting device at least indirectly connected to the vehicle body for lifting the storage bin into the cavity, driving means connected to the vehicle body allowing remotely controlled movements of the vehicle assembly within the storage system, wireless communication means for providing wireless communication between the vehicle assembly and a remote control unit such as a computer, one or more main power sources supplying electrical power to the driving means and vehicle coupling means for operational and releasable coupling of the main power source to the vehicle body.
Abstract:
The present invention concerns a remotely operated vehicle or robot for picking up storage bins from a storage system. The inventive vehicle or robot comprises a vehicle body, which vehicle body further comprises a first section for storing vehicle driving means and a second section for receiving any storage bin stored in a storage column within the storage system, a vehicle lifting device which is at least indirectly connected to the vehicle body in order to lift the storage bin into the second section, a first set of vehicle rolling means connected to the vehicle body in order to allow movement of the vehicle along a first direction (X) within the storage system during use and a second set of vehicle rolling means connected to the vehicle body in order to allow movement of the vehicle along a second direction (Y) in the storage system during use. The second direction (Y) is oriented perpendicular to the first direction (X). The inventive vehicle is characterized in that the second section comprises a cavity arranged centrally within the vehicle body. This cavity has at least one bin receiving opening facing towards the underlying storage columns during use. In addition, at least one of the two sets of vehicle rolling means is arranged fully within the vehicle body.

Abstract:
The present invention relates to a bin storage system (3) comprising a three-dimensional bin storage structure (15) and a plurality of robot vehicles (1) which are movable on top of the bin storage structure to retrieve storage bins (2) from the structure. The structure comprises: pillars which are positioned with internal distances and in a rectangular arrangement accommodating the bins and defining storage columns (8, 8a, 8b) for the bins; supporting rails (13) arranged in a matrix on top of the pillars providing support (14) for the robot vehicles and allowing each robot vehicle to travel across the structure in a first direction (X) and in a second direction (Y); a storage bin delivery station (60); and a bin lift device (50) which receives bins from the robot vehicles and transport them in a vertical direction from a top level of the structure to the delivery station. Each robot vehicle comprises a vehicle body (4) having: first and second sets of rolling means (10, 11) for moving the robot vehicle along the supporting rails; a cavity (7) for receiving a bin; and a lifting device (9) for retrieving a bin from a storage column and storing the bin in the cavity.
