Abstract

A warehousing system for storing and retrieving goods disposed in containers is provided. The system includes a multilevel storage array including an array of storage shelves for holding containers thereon, at least one substantially continuous lift for transporting containers to and from at least one level of the storage array, at least one transport vehicle located on the at least one level and configured to traverse a transport area transporting containers between the at least one continuous lift and container storage locations so that the at least one continuous lift communicates non-deterministically, via the transport vehicle, with storage locations of each of the storage shelves on the at least one level, an infeed transport system linked to the at least one continuous lift, and an order fulfillment station for generating order containers corresponding to customer orders where the order containers are entered onto the storage shelves of the storage array.

Claims

1. An order fulfillment station arranged for filling, from stock goods, disposed in product containers, order containers corresponding to a customer order and holding order goods designated by a customer order, the fulfillment station comprising:

an operator station where an operator is resident for picking stock goods from product containers and placing into order containers;

a product container station configured for positioning the product containers for picking stock goods therefrom by the operator at the operator station, the product container station being arranged to define more than one product container holding locations; and

an order container station configured for positioning the order containers for placing order goods thereinto by the operator at the operator station, the order container station defining more than one order container holding locations,

wherein the product container station and the order container station have predetermined characteristics that define handedness features for picking from product containers at the more than one product container holding locations, each product container holding location having a different handedness than an adjacent product container holding location.

2. The order fulfillment station of claim 1, wherein the predetermined characteristics that define handedness features comprise at least one display configured to indicate a number of stock goods to be transferred from a product container on one side of the operator and placed into an order container disposed on the one side of the operator.

3. The order fulfillment station of claim 1, wherein the predetermined characteristics that define handedness features comprise a communication device configured to indicate a number of stock goods to be transferred from a product container on one side of the operator and placed into an order container disposed on the one side of the operator.

4. The order fulfillment station of claim 1, wherein the predetermined characteristics that define handedness features comprise a left and right product container station and a left and right order container station, wherein stock goods removed from product containers at the left product container station are placed in order containers at the left order container station and items removed from product containers at the right product container station are placed in order containers at the right order container station.

5. The order fulfillment station of claim 1, wherein the product container station includes a left hand and a right hand product container station, the predetermined characteristics that define handedness features comprise the operator station being disposed such that the left hand product container station is located on a left hand side of the operator station and the right hand product container station is located on a right hand side of the operator station.

6. The order fulfillment station of claim 1, wherein the order container station includes a left hand and a right hand order container station, the predetermined characteristics that define handedness features comprise the operator station being disposed such that the left hand order container station is located on a left hand side of the operator station and the right hand order container station is located on a right hand side of the operator station.

7. An order fulfillment station arranged for filling, from stock goods, disposed in product containers, order containers corresponding to a customer order and holding order goods designated by a customer order, the fulfillment station comprising:

an operator station where an operator is resident for picking stock goods from product containers and placing into order containers;

a product container station configured for positioning the product containers for picking stock goods therefrom by the operator at the operator station, the product container station being arranged to define more than one product container holding location;

an order container station configured for positioning the order containers for placing order goods thereinto by the operator at the operator station, the order container station defining more than one order container holding location;

wherein the more than one product container holding location and the more than one order container holding location are configured for substantially simultaneous ambidextrous picking and placing by the operator at the operator station, the more than one product container holding locations being indexed to the one or more order container holding stations so that picking and placing is effected deterministically between indexed product container holding stations and order container holding stations.

8. The order fulfillment station of claim 7 wherein the one or more product container location comprises a first product container location disposed on a right hand side of the operator station and a second product container location disposed on a left hand side of the operator station and the one or more order container location comprises a first order container location disposed on a right hand side of the operator station and a second order container location disposed on a left hand side of the operator station, wherein the left and right hand product and order containers are positioned so that stock goods are substantially simultaneously removed from the left and right hand product container stations and placed in a respective one of the left and right hand order container stations.

9. The order fulfillment station of claim 7, further comprising at least one of an aural and visual indicator configured to indicate a number of stock goods to be removed from the product containers for placement into a corresponding one of the order containers.

10. The order fulfillment station of claim 7, further comprising an order container conveyor and a product container conveyor and a controller connected to each of the order container conveyor and product container conveyor, the controller being configured to control movement of containers on each of the conveyors such that product containers containing stock goods to be transferred to a predetermined order container are delivered to a corresponding product container holding location while the predetermined order container is located at a predetermined order container holding station.
