Abstract

Systems and methods of controlling material flow can be used to streamline order fulfillment. For example, according to some embodiments described herein, takt times of goods-to-person order picking work cell processes are enhanced to expedite order processing. A goods-to-person order picking process involves moving items for an order directly to a work cell of an operator or an automated system. At order processing work cells, one or more items are transferred from origin containers and placed in shipping containers in accordance with customer orders. Work cell redundancy can be utilized to enhance efficiencies of goods-to-person order picking processes in some cases.

First claim

What is claimed is:

1. An order processing method, comprising:
conveying, to a first workstation of an order processing work cell, two or more first origin containers, the two or more first origin containers carrying sellable items called for by a first customer order;
conveying, to the first workstation of the order processing work cell, a first destination container;
transferring, by a single human worker, one or more of the sellable items from the two or more first origin containers to the first destination container in accordance with the first customer order;
conveying, to a second workstation of the order processing work cell, two or more second origin containers, the two or more second origin containers carrying sellable items called for by a second customer order, wherein the first workstation is near to the second workstation such that the single human worker can operate both the first workstation and the second workstation;
conveying, to the second workstation of the order processing work cell, a second destination container;
after the transferring of the one or more of the sellable items from the two or more first origin containers to the first destination container, moving, by the single human worker, from the first workstation to the second workstation;
after the moving of the single human worker from the first workstation to the second workstation, transferring, by the single human worker, one or more of the sellable items from the two or more second origin containers to the second destination container in accordance with the second customer order;
during the transferring of the one or more of the sellable items from the two or more second origin containers to the second destination container, conveying the two or more first origin containers and the first destination container away from the first workstation;
after the conveying of the two or more first origin containers and the first destination container away from the first workstation and during the transferring of the one or more of the sellable items from the two or more second origin containers to the second destination container, conveying to the first workstation, a third destination container and two or more third origin containers, the two or more third origin containers carrying sellable items called for by a third customer order;
after the transferring of the one or more of the sellable items from the two or more second origin containers to the second destination container, moving, by the single human worker, from the second workstation to the first workstation; and
after the moving of the single human worker from the second workstation to the first workstation, transferring, by the single human worker, one or more of the sellable items from the two or more third origin containers to the third destination container in accordance with the third customer order.

2. The method of claim 1 , wherein the conveying steps of the method are performed by one or more mobile robots.

3. The method of claim 1 , wherein the conveying steps of the method are performed by one or more conveyors.

4. The method of claim 1 , wherein the two or more first origin containers are staged in multiple elevations in the first workstation.

5. The method of claim 1 , wherein the two or more second origin containers are staged in multiple elevations in the second workstation.

6. The method of claim 1 , wherein the two or more first origin containers and the first destination container are differing types of storage units.

7. The method of claim 1 , wherein the two or more second origin containers and the second destination container are differing types of storage units.

8. The method of claim 1 , wherein each of the two or more first origin containers carries only a single type of sellable item.

9. The method of claim 1 , wherein at least one of the two or more first origin containers carries multiple types of sellable items.
