Tote handling for chilled or frozen goods
An automated order fulfillment system is disclosed having different temperature zones and robots and containers capable of and/or configured to work in these different temperature zones. Containers include insulated wall panels and a thermal insert which may be chilled to maintain a temperature within the container below ambient temperature. Structure within a storage location for the containers may be used to open and close the containers to facilitate cooling of the thermal insert.
1. A system for transporting and storing a container in an automatic storage and retrieval facility, the container comprising material within an interior of the container to chill the interior of the container below ambient temperature, the system comprising:
a storage location for storing the container, the storage location comprising:
a cold air source configured to cool and regenerate the material to a temperature below a predetermined phase transition temperature of the material, and
a structure affixed to the storage location configured to open a lid of the container to allow access to the material within the interior of the container facilitating regeneration of the material by the cold air source.
2. The system of claim 1 , wherein the structure is a passive, stationary structure configured to engage and open the lid as the container is transferred into the storage location.
3. The system of claim 2 , wherein the structure is configured to close the lid as the container is transferred away from the storage location.
4. The system of claim 2 , wherein the structure comprises a stationary curved ramp configured to engage tabs in the lid as the lid is transferred into the storage location.
5. The system of claim 1 , wherein the cold air source comprises at least one of a fan and a duct configured to direct cold air toward the container when positioned in the storage location.
6. The system of claim 1 , wherein the cold air source comprises an enclosed refrigerated space in which the storage location is located.
7. The system of claim 1 , wherein the cold air source is configured to deliver cold air at a first temperature where the container is to store chilled goods, and the cold air source is configured to deliver cold air at a second temperature, colder than the first temperature, where the container is to store frozen goods at a temperature colder than the chilled goods.
8. The system of claim 1 , wherein the storage location comprises a first storage location, the container comprises a first container, the material comprises a first material, the cold source comprises a first cold source configured to deliver cold air at a first temperature, and the structure comprises a first structure, the system further comprising:
a second storage location for storing a second container, the second container comprising a second material within an interior of the second container to chill the interior of the second container to a temperature below a chilled temperature of the first container, the second storage location comprising:
a second cold air source configured to cool and regenerate the second material to a temperature below a predetermined phase transition temperature of the second material, and
a second structure at the second storage location configured to open a lid of the second container to allow access to the second material within the interior of the second container facilitating regeneration of the second material by the second cold air source.
9. A system for transporting and storing a container in an automatic storage and retrieval facility, the container comprising material within an interior of the container to chill the interior of the container below ambient temperature, the system comprising:
a storage location for storing the container, the storage location comprising:
a cold air source configured to cool and regenerate the material to a temperature below a predetermined phase transition temperature of the material, and
a ramp at the storage location configured to engage a lid of the container as the container moves to open the lid and to allow access to the material within the interior of the container facilitating regeneration of the material by the cold air source.
10. The system of claim 9 , wherein the ramp is a passive, stationary structure configured to engage and open the lid as the container is transferred into the storage location.
11. The system of claim 10 , wherein the ramp is configured to close the lid as the container is transferred away from the storage location.
12. The system of claim 10 , wherein the ramp comprises a stationary curved shape configured to engage tabs in the lid as the lid is transferred into the storage location.
13. The system of claim 9 , wherein the cold air source comprises at least one of a fan and a duct configured to direct cold air toward the container when positioned in the storage location.
14. The system of claim 9 , wherein the cold air source comprises an enclosed refrigerated space in which the storage location is located.
15. The system of claim 9 , wherein the cold air source is configured to deliver cold air at a first temperature where the container is to store chilled goods, and the cold air source is configured to deliver cold air at a second temperature, colder than the first temperature, where the container is to store frozen goods at a temperature colder than the chilled goods.
16. The system of claim 9 , wherein the storage location comprises a first storage location, the container comprises a first container, the material comprises a first material, the cold source comprises a first cold source configured to deliver cold air at a first temperature, and the ramp comprises a first ramp, the system further comprising:
a second storage location for storing a second container, the second container comprising a second material within an interior of the second container to chill the interior of the second container to a temperature below a chilled temperature of the first container, the second storage location comprising:
a second cold air source configured to cool and regenerate the second material to a temperature below a predetermined phase transition temperature of the second material, and
a second ramp at the second storage location configured to engage and open a lid of the second container to allow access to the second material within the interior of the second container facilitating regeneration of the second material by the second cold air source.
