Abstract

A storage system includes a remotely operated vehicle, a vehicle support, a bin storing structure and a bin lift device. The vehicle support is configured to guide movements of the remotely operated vehicle in first and second directions. The bin storing structure supports the vehicle support and includes storage columns, arranged to accommodate a vertical stack of storage bins. The bin lift device is arranged to convey a vehicle delivered storage bin in a direction perpendicular to the lateral plane of the vehicle support between the vehicle support and a delivery station. The remotely operated vehicle includes a vehicle body including a first section for storing vehicle driving means and a second section for receiving a storage bin, a vehicle lifting device for lifting the storage bin into the second section, and sets of vehicle rolling means allowing movement of the vehicle in the first and second directions.

First claim

What is claimed is:

1. A storage system comprising:
a remotely operated vehicle;
a vehicle support comprising a plurality of supporting rails forming a two dimensional matrix of guiding meshes, the vehicle support being configured to guide movements of the remotely operated vehicle in a first direction and a second direction during use;
a bin storing structure supporting the vehicle support, the structure comprising a plurality of storage columns, wherein each of the storage columns is arranged to accommodate a vertical stack of storage bins, and the main part of the bin storing structure coincides with positions on the vehicle support where the supporting rails are crossing; and
a bin lift device arranged to convey a vehicle delivered storage bin in a direction perpendicular to the lateral plane of the vehicle support between the vehicle support and a delivery station,
wherein the remotely operated vehicle comprises:
a vehicle body comprising 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, the second section comprising a centrally arranged cavity within the vehicle body, the cavity having at least one bin receiving opening facing towards the storage columns during use;
a vehicle lifting device at least indirectly connected to the vehicle body for the storage bin into the second section; and
a first set of vehicle rolling means connected to the vehicle body allowing movement of the vehicle along the first direction 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 the second direction in the storage system during use, the second direction being perpendicular to the first direction, at least one of the sets of vehicle rolling means being arranged fully within the vehicle body.

2. The storage system according to claim 1 , wherein the vehicle further comprises means for reversibly and selectively displacing either the first set of vehicle rolling means or the second vehicle rolling means away from an underlying vehicle support within the storage system during a change of vehicle direction between the first direction and the second direction.

3. The storage system according to claim 1 , wherein the vehicle body covers at most the lateral cross section of one central storage column in the first direction and covers the lateral cross section of more than one central storage column in the second direction during use.

4. The storage system according to claim 1 , wherein both sets of vehicle rolling means are symmetrically distributed around the centrally arranged cavity.

5. The storage system according to claim 1 , wherein at least one set of vehicle rolling means comprises at least four wheels.

6. The storage system according to claim 1 , wherein both sets of vehicle rolling means have an exterior design matching a corresponding exterior design on supporting rails constituting the vehicle support in order to provide increased lateral stability when interconnected, wherein the supporting rails are arranged in a two dimensional matrix on top of a bin storing structure, the principal directions of the matrix and the bin storing structure being congruent with the first direction and second direction of the vehicle.

7. The storage system according to claim 1 , wherein the vehicle body extends beyond the lateral cross section of the central storage column at both sides in the second direction.

8. The storage system according to claim 7 , wherein the extension beyond the lateral cross section of the central storage column is equal on both sides in the second direction.

9. The storage system according to claim 1 , wherein the vehicle comprises position sensing means to allow measurements of the vehicle position within the storage system during use.

10. The storage system according to claim 9 , wherein the position sensing means comprise a plurality of sensors arranged in at least some of the positions on the vehicle body which, during use, traverse the positions of vehicle support where the supporting rails are crossing.

11. The storage system according to claim 1 , wherein at least some of the supporting rails, arranged at the outer lateral border areas of the vehicle support, form outer guiding meshes having reduced average cross section compared to the average cross section of the remaining guiding meshes in the vehicle support.

12. The storage system according to claim 11 , wherein the average reduced cross section of the outer guiding meshes are about half of the average cross section of the remaining guiding meshes in the vehicle support.

13. The storage system according to claim 11 , wherein the size of the outer guiding meshes are reduced only along the second direction of the vehicle support.
