Abstract

Methods and apparatus for material handling in an order fulfillment center. Embodiments may include one or more flexible, modular processing modules that may be configured to receive one or more inventory items that are to be processed for shipment. The received inventory items may correspond to single-item customer orders, or to multi-item customer orders. A pre-packaging station of the processing module may be configured to receive the one or more inventory items and to perform pre-packaging operations to produce a pre-packaged unit. The pre-packaged unit may include the one or more inventory items and a pre-packaging substrate. The processing module may also include an inspection station configured to automatically verifying one or more dimensions of the pre-packaged unit. The processing module may further include a packaging station configured to perform packaging operations to produce a packaged unit.

2. The order-processing module of claim 1, wherein the order-processing module is reconfigurable to produce other packaged units conforming to a size that is different from the particular size of the particular packaged unit.

3. The order-processing module of claim 1,

wherein the one or more inventory items included in the particular packaged unit is a single inventory item;

and

wherein the at least one other packaged unit includes at least two inventory items.

4. The order-processing module of claim 1, wherein the receiving station includes:

a sorting station that is configured to receive and group inventory items corresponding to multi-item orders, and to convey the grouped inventory items to the pre-packaging station; and

a single-order conveyance mechanism that is configured receive inventory items corresponding to single-item orders, and to convey the received inventory items to the pre-packaging station without conveying the received inventory items to the sorting station.

5. The order-processing module of claim 1, wherein the pre-packaging operations further include:

affixing an identification label to the pre-packaging substrate; and

securing the one or more inventory items to the pre-packaging substrate.

6. The order-processing module of claim 1,

wherein the automatically verifying the one or more dimensions is performed using a vision-based system;

and

wherein the inspection operations further comprise verifying that an identification label is readable.

7. The order-processing module of claim 1, wherein the order-processing module is further configured to:

divert the pre-packaged unit for further processing in response to determining that the inspection operations detect a defect condition.

8. The order-processing module of claim 1, further comprising:

a pre-shipping station configured to;

receive the particular packaged unit from the packaging station;

add a shipping label to the particular packaged unit; and

perform one or more quality assurance operations using the particular packaged unit.

9. The order-processing module of claim 8, wherein the pre-shipping station is further configured to:

select a particular shipping module from a plurality of shipping modules for conveyance of the particular packaged unit, based at least in part on information associated with the particular packaged unit.

10. An order-processing module, comprising:

a receiving station configured to receive one or more inventory items;

a pre-packaging station configured to receive the one or more inventory items from the receiving station and to perform pre-packaging operations on the one or more inventory items to produce a pre-packaged unit;

an inspection station configured to receive the pre-packaged unit from the pre-packaging station and to perform automated inspection operations that include verification that one or more dimensions of the pre-packaged unit conform to specifications required for successful automated construction of outer packaging around the pre-packaged unit; and

a packaging station configured to receive the pre-packaged unit from the inspection station and to perform packaging operations to produce a particular packaged unit, wherein the packaging operations include automated construction of carton-based outer packaging around the pre-packaged unit while the pre-packaged unit is within the carton-based outer packaging;

wherein the order-processing module is configured to produce a plurality of types of packaged units conforming to a particular size, wherein the plurality of types comprises a type corresponding to the particular packaged unit, and a type corresponding to at least one other packaged unit that includes a different item from the one or more inventory items of the particular packaged unit.

11. The order-processing module of claim 10, wherein the pre-packaging operations further include:

affixing an identification label to a carrier, wherein the identification label corresponds to an order associated with the one or more inventory items; and

securing the one or more inventory items to the carrier using a shrink wrapping process;

wherein the pre-packaged unit includes the one or more inventory items and the carrier.

12. The order-processing module of claim 10, wherein the receiving the one or more inventory items at the receiving station includes:

receiving a plurality of inventory items corresponding to a particular multi-item order, wherein at least two of the plurality of inventory items are received at different times;

grouping the plurality of inventory items corresponding to the particular multi-item order in a conveyance receptacle; and

conveying the particular conveyance receptacle to the pre-packaging station after each of the plurality of inventory items corresponding to the particular multi-item order have been received and grouped.

13. The order-processing module of claim 10, wherein the verification that one or more dimensions of the pre-packaged unit conform to specifications required for successful automated construction of outer packaging is performed using a vision-based system that comprises a set of cameras.
