Object handling system and method
A vehicle for use with an object handling system, the object handling system including two substantially perpendicular sets of rails forming a first grid, a plurality of first uprights supporting the first grid, a plurality of containers arranged in stacks, each stack being located underneath the first grid, one or more robotic load handling devices configured to drive on top of the rails of the first grid, the one or more load handling devices including means for removing or replacing at least one container from the stacks. The vehicle includes two substantially perpendicular sets of rails forming a second grid substantially at the top of the vehicle above a storage space for carrying containers. The second grid interfaces with the first grid to allow the one or more load handling devices to drive from the rails of the first grid onto the rails of the second grid.
1. A vehicle for use with an object handling system, the object handling system including two substantially perpendicular sets of rails forming a first grid, a plurality of first uprights supporting the first grid, a plurality of containers arranged in stacks, each stack being located underneath the first grid, one or more robotic load handling devices configured to drive on top of the rails of the first grid, the one or more load handling devices including means for removing or replacing at least one container from the stacks, the vehicle comprising:
two substantially perpendicular sets of rails forming a second grid substantially at the top of the vehicle above a storage space for carrying containers, wherein the second grid is configured to interface with the first grid to allow the one or more load handling devices to drive from the rails of the first grid onto the rails of the second grid to move a container from the object handling system to the storage space of the vehicle and vice versa.
2. The vehicle according to claim 1 , wherein the second grid forms part of the structure of the vehicle.
3. The vehicle according to claim 2 , wherein the second grid forms the roof of the vehicle.
4. The vehicle according to claim 1 , wherein the second grid is mounted on the roof of the vehicle.
5. The vehicle according to claim 2 , wherein the second grid is mounted on the roof of the vehicle.
6. The vehicle according to claim 1 , wherein the second grid is covered by a deployable tarpaulin or a retractable roof.
7. The vehicle according to claim 1 , wherein the sides of the vehicle are fixed, flexible or retractable.
8. The vehicle according to claim 1 , comprising:
a trailer defining the storage space and the second grid is substantially at the top of the trailer.
9. The vehicle according to claim 1 , wherein the storage space is refrigerated.
10. An object handling system, the object handling system comprising:
two substantially perpendicular sets of rails forming a first grid;
a plurality of first uprights supporting the first grid;
a plurality of containers arranged in stacks, each stack being located underneath the first grid;
one or more robotic load handling devices configured to drive on top of the rails of the first grid, the one or more load handling devices comprising means for removing or replacing at least one container from the stacks; and
a vehicle according to claim 1 .
11. An object handling system, comprising:
two substantially perpendicular sets of rails forming a first grid;
a plurality of first uprights supporting the first grid;
a plurality of containers arranged in stacks, each stack being located underneath the first grid;
one or more robotic load handling devices configured to drive on top of the rails of the first grid, the one or more load handling devices comprising means for removing or replacing at least one container from the stacks; and
an alignment mechanism configured to align a portion of the rails of the first grid with a portion of the rails of a second grid of a vehicle according to claim 1 .
12. The object handling system according to claim 11 , wherein the alignment mechanism comprises a plate or stand configured to receive at least a part of the vehicle, and the plate or stand is movable in the X, Y and Z directions relative to the first grid.
13. The object handling system according to claim 12 , wherein the plate is tiltable, or the stand is rotatable about a vertical axis.
14. The object handling system according to claim 12 , wherein the alignment mechanism comprises motorized mechanical means or hydraulic means for moving the plate or stand.
15. The object handling system according to claim 13 , wherein the alignment mechanism comprises motorized mechanical means or hydraulic means for moving the plate or stand.
16. The object handling system according to claim 10 , wherein the first grid comprises an interface portion configured to interface with the second grid, and the interface portion is located above a loading and unloading bay for the vehicle.
17. The object handling system according to claim 10 , wherein:
the two sets of rails forming the first grid and the two sets of rails forming the second grid includes a first set of parallel rails and a second set of parallel rails arranged perpendicular to the first set of parallel rails; and
the load handling device includes a body mounted on a first set of wheels and a second set of wheels, the first set of wheels being arranged to engage with at least two rails of the first set of rails, and the second set of wheels being arranged to engage with at least two rails of the second set of rails, the first set of wheels being independently moveable and driveable with respect to the second set of wheels such that when in motion only one set of wheels is engaged with the first grid or the second grid at any one time thereby enabling movement of the load handling device along the rails to any point on the first grid or the second grid by driving only the set of wheels engaged with the rails.
