Storage system
A storage system includes a first grid structure of storage cells. Each cell is arranged to accommodate a vertical stack of storage bins. The first grid structure has a top level. The system further includes a first vehicle, arranged to move horizontally at the top level of the first grid structure, and a bin lift device, arranged to convey a bin in a vertical direction between the top level of the grid structure and a delivery station. The first vehicle is further arranged 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 the bin lift device. The bin lift device is arranged to receive a bin from the vehicle at the top level of the first grid structure and to convey the bin to the delivery station. The storage system further includes one or more additional grid structures of storage cells at a different vertical level than the first grid structure, and additional vehicles that is arranged to move horizontally at the top level of the additional grid structures.
1. A Storage system, comprising a grid structure of storage cells, each storage cell of the grid structure being arranged to accommodate a vertical stack of storage bins, the grid structure having a top level comprising tracks arranged horizontally along two axes, a vehicle having two sets of wheels, arranged to move horizontally along the tracks at the top level of the grid structure, and at least two bin lift devices, wherein each bin lift device among the at least two bin lift devices is arranged to convey a storage bin within the grid structure in a vertical direction between the top level of the grid structure and a delivery station,
wherein the vehicle is further arranged to receive a storage bin from a storage cell at the top level of the grid structure and to deliver the storage bin directly to one of the bin lift devices,
wherein the one of the bin lift devices is arranged to receive a storage bin directly from the vehicle at the top level of the grid structure and to convey the storage bin without the vehicle to the delivery station,
wherein the one of the bin lift devices comprises a movable support arranged to slide in a vertical frame;
wherein the one of the bin lift devices is arranged to travel vertically within the grid structure; and
wherein the one of the bin lift devices has a storage cell on each opposite horizontal side.
2. The storage system according to claim 1 , wherein the vertical frame travels along vertical columns arranged to coincide with corners of the storage bin being transported.
3. The storage system according to claim 2 , further comprising a control unit and network communication devices configured to provide wireless communication between the control unit and the vehicle.
4. The storage system according to claim 1 , further comprising a control unit and network communication devices configured to provide wireless communication between the control unit and the vehicle.
