Abstract

A storage system is described where goods are stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of tracks on which load handling devices run. The load handling devices take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked out. The framework may be provided with one or more of the following services: power, power control, heating, lighting, cooling, sensing, and data logging. A method of partitioning the storage system prevents the spread of fire or prevent damage caused by sprinkler activation.

First claim

The invention claimed is:

1. A storage system comprising:
a first set of parallel rails and a second set of parallel rails extending transverse to the first set in a substantially horizontal plane to form a grid having a plurality of grid spaces;
a set of uprights, the uprights and rails together defining a framework;
a plurality of storage containers arranged in stacks, located beneath the rails and within the framework; and
at least one load handling device disposed above and operable on the rails, arranged to move laterally above the stacks on the rails, the at least one load handling device having a lifting device arranged to lift one or more containers, or parts thereof, from a stack;
wherein the system includes deployable partition means, the deployable partition means being positioned adjacent the underside of the grid and arranged to divide the storage system into separately sealable portions while allowing the at least one load handling device access to the plurality of storage containers arranged in the stacks, such that the movement of the at least one load handling device operative on the rails is unimpeded.

2. The storage system of claim 1 , wherein the deployable partition means is activated in response to a predetermined event, and is positioned beneath and operable from under a level of the rails and divides the storage system into separately sealable portions.

3. A storage system according to claim 1 , comprising:
walkway means disposed above the deployable partition means.

4. A storage system according to claim 1 , comprising:
guard rail means disposed above the deployable partition means.

5. A storage system according to claim 1 , wherein the deployable partition means is a remotely deployable partition, deployable in response to a predetermined trigger from a sensor located within the framework.

6. A storage system according to claim 5 , wherein the deployable partition is in the form of a roller or shutter powered by a motor.

7. A storage system according to claim 5 , wherein the sensor comprises:
a smoke detector or a temperature sensor or a fire alarm.

8. The storage system according to claim 5 , wherein a portion of the framework is configured to provide power supply to at least one of the sensor, or the deployable partition.

9. A storage system according to claim 5 , wherein a portion of the framework is configured to control power to at least one of the sensor, or the deployable partition.

10. A storage system according to claim 1 , wherein a portion of the framework comprises:
sensor means and data logging means for monitoring an output of the sensor means.

11. The storage system of claim 10 , wherein a portion of the framework is configured to provide and/or control power supply to the data logging means.

12. A storage system according to claim 1 , wherein the framework is configured to enable communication between adjacent containers within the storage system or with a system controller.

13. A storage system according to claim 1 , wherein at least one of the containers is configured to heat the contents of the containers.

14. A storage system according to claim 1 , wherein at least one of the containers is configured to cool the contents of the containers.

15. A storage system according to claim 1 , wherein at least one of the containers is configured to sink a fluid in the containers.

16. A storage system according to claim 1 , wherein at least one of the containers is configured with lighting.

17. A storage system according to claim 16 , wherein the load handling device is configured to isolate at least one of the stacks from the rest of the storage system.

18. A storage system according to claim 1 , in which at least one individual container in the stack is provided with a unique identity, the identity being traceable and trackable by a sensor and monitoring means.

19. A method of dividing a storage system into separably sealable portions, the storage system having a framework, with a substantially horizontal grid mounted on substantially vertical uprights, the system including a plurality of stacked containers disposed within the framework, and deployable partition means positioned adjacent the underside of the grid and acting to divide the storage system into separately sealable portions, such that the movement of at least one load handling device operative on rails, which form the substantially horizontal grid, is unimpeded, the method comprising:
providing the deployable partition means on an underside of the grid;
deploying said deployable partitioning means from a retracted position in response to a predetermined signal while allowing the at least one load handling device access to the plurality of stacked containers disposed within the framework; and
urging the deployable partitioning means against a base of the storage system.
