Storage systems and methods
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. The provision of these services within the framework rather than across the system as a whole, allows for flexibility in storage whilst reducing cost and inefficiency.
1. A storage system comprising:
a first set of parallel rails or tracks and a second set of parallel rails or tracks extending transverse to the first set in a substantially horizontal plane to form a grid pattern having a plurality of grid spaces;
a set of uprights, the uprights and tracks together defining a framework;
a plurality of storage containers arranged in stacks, located beneath the rails and within the framework;
at least one load handling device disposed on and above the rails or tracks, the at least one load handling device including a body mounted on wheels, a first set of wheels arranged to engage with two rails of the first set of parallel rails, a second set of wheels arranged to engage with 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 tracks or rails at any one time thereby enabling movement of the load handling device along the rails to any point on the grid by driving only the set of wheels engaged with the tracks or rails, the at least one load handling device including a lifting device arranged to lift one or more containers, or parts thereof, from a stack;
wherein the framework includes a service means for providing services to the storage system and the containers located therein enabling interaction, control and monitoring of the system from within the framework.
2. The storage system according to claim 1 , wherein a portion of the framework comprises:
a power control means.
3. The storage system according to claim 1 , wherein a portion of the framework comprises:
a sensor means and a data logging means for monitoring the output of the sensor means.
4. The storage system according to claim 1 , wherein the framework comprises:
a communication means for communicating with adjacent containers or with a central communications manager.
5. The storage system according to claim 1 , wherein some or all of the containers comprise:
a heating means for heating the contents of containers.
6. The storage system according to claim 1 , wherein some or all of the containers comprise:
a cooling means for cooling the contents of containers.
7. The storage system according to claim 1 , wherein some or all of the containers comprise:
a reservoir, the reservoir acting as a fluid sink in the container.
8. The storage system according to claim 1 , wherein some or all of the containers comprise:
a lighting means.
9. The storage system according to claim 8 , wherein the lighting means comprises:
a lid removeably attached to a respective container in the stack.
10. The storage system according to claim 1 , wherein an individual container in the stack is provided with a unique identity, the identity being traceable and trackable by a sensor and a monitoring means.
11. The storage system according to claim 1 , wherein the framework comprises a connection means for connecting the framework to the containers within the stacks, thereby enabling interaction between the framework and the containers, and enabling services to be provided thereto.
12. The storage system according to claim 1 , wherein a portion of the framework comprises:
a power supply means.
13. The storage system according to claim 12 , wherein a portion of the framework comprises:
a power control means.
14. The storage system according to claim 13 , wherein a portion of the framework comprises:
the sensor means and the data logging and storage means for monitoring the output of the sensor means.
15. The storage system according to claim 14 , wherein the framework comprises:
a communication means for communicating with adjacent containers or with a central communications manager.
16. The storage system according to claim 15 , wherein some or all of the containers comprise:
a heating means for heating the contents of containers.
17. The storage system according to claim 16 , wherein some or all of the containers comprise:
a cooling means for cooling the contents of containers.
18. The storage system according to claim 17 , wherein some or all of the containers comprise:
a reservoir, the reservoir acting as a fluid sink in the container.
19. The storage system according to claim 18 , wherein some or all of the containers comprise:
a lighting means.
20. The storage system according to claim 19 , in which an individual container in the stack is provided with a unique identity, the identity being traceable and trackable by a sensor and a monitoring means.
21. A method of condition monitoring a storage system including a first set of parallel rails or tracks and a second set of parallel rails or tracks extending transverse to the first set in a substantially horizontal plane to form a grid pattern having a plurality of grid spaces, a set of uprights, the uprights and tracks together defining a framework, a plurality of storage containers arranged in stacks, located beneath the rails and within the framework, at least one load handling device disposed on and above the rails or tracks, the at least one load handling device including a body mounted on wheels, a first set of wheels arranged to engage with two rails of the first set of parallel rails, a second set of wheels arranged to engage with 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 tracks or rails at any one time thereby enabling movement of the load handling device along the rails to any point on the grid by driving only the set of wheels engaged with the tracks or rails, the at least one load handling device including a lifting device arranged to lift one or more containers, or parts thereof, from a stack, the method comprising:
a. providing a sensor means and a data logging and storage means within the framework formed by first and second parallel rails or tracks and a set of uprights;
b. providing a communication means to communicate data logged within the framework to a central data logging device; and
c. monitoring the data received.
