Abstract

Systems for decanting inventory products from cases at a retail facility include a loading zone that receives product cases, decanting stations having associated containers with an amount of available space therein, and a decanting transport system that transports the product cases from the loading zone to the decanting stations and has sensors that obtain information relating to the product cases. A processor-based control circuit receives from the sensors information relating to product cases being transported from the loading zone by the decanting transport system, selects a subset of the product cases, analyzes one or more business rules governing decanting to assign each product case in the subset to a decanting station, and causes the decanting transport system to divert each product case in the subset to its assigned decanting station based on the one or more business rules.

First claim

What is claimed is:

1 . A system for decanting inventory products from cases at a retail facility, the system comprising:
a loading zone configured to receive product cases, each product case containing a quantity of a product; a plurality of decanting stations, each decanting station having at least one container associated therewith, each container having an amount of available space for receiving at least one product; a decanting transport system comprising a conveyor having a product advancement surface configured to transport the product cases from the loading zone to the decanting stations, the decanting transport system comprising one or more sensors configured to obtain information relating to the product cases as they are conveyed by the conveyor; a control unit operatively coupled to the decanting transport system and configured to control movement of the conveyor; and a control circuit communicatively coupled to the control unit, the control circuit being configured to:
receive, from the one or more sensors, information relating to a plurality of product cases conveyed by the conveyor;
select a subset of product cases from the plurality of product cases, wherein the subset comprises at least two product cases from the plurality of product cases;
apply a container-packing algorithm to the subset of product cases and the containers at the decanting stations to determine a minimum number of containers needed to decant all of the products in the subset of product cases into the containers based on a projected utilization of each container, the projected utilization of each container being determined by the control circuit based on one or more dimensions of the products and an optimal packing configuration of the products when the products are stacked in the containers, wherein the optimal packing configuration is a projected packing configuration having a greatest height of the products in the container, with a maximum height being a height of the container, and a lowest area of the products in the container;
assign each product case in the subset to one of the plurality of decanting stations based on the optimal packing configurations of the products in the containers;
cause the conveyor to divert each product case in the subset to its assigned decanting station; and
cause the conveyor to recirculate non-selected ones of the plurality of product cases for selection into a subsequent subset of product cases.

2 . The system of claim 1 , wherein each decanting station further comprises a user display and the control circuit is configured to cause the user display to display an instruction for packing the products from the product cases into the container.

3 . The system of claim 1 , wherein the control circuit is configured to analyze a workload of the plurality of decanting stations to identify one or more decanting stations that can accommodate decanting.

4 . The system of claim 1 , wherein the control circuit is further configured to determine a cost function associated with diverting each product case in the subset of product cases to each decanting station and cause the product cases to be diverted to assigned decanting stations based also on the cost functions.

5 . The system of claim 1 , wherein the information relating to the product cases comprises one or more of an identity of a product in the product case, a quantity of the product in the product case, one or more dimensions of the product in the product case, one or more dimensions of the product case, a weight of the product in the product case, and a weight of the product case.

6 . The system of claim 1 , wherein at least two product cases in the subset are assigned to and diverted to different decanting stations.

7 . The system of claim 1 , wherein at least two product cases in the subset are assigned to and diverted to a same decanting station.

8 . The system of claim 1 , wherein the control circuit is further configured to apply another container-packing algorithm to the subset of product cases and the containers at the decanting stations and the control circuit assigns each product case in the subset to a decanting station.

9 . A method of decanting inventory products from cases at a retail facility, the method comprising:
receiving, by a control circuit, from one or more sensors associated with a decanting transport system, information relating to a plurality of product cases being transported by a conveyor having a product advancement surface, each product case containing a quantity of product, wherein the conveyor of the decanting transport system is configured to transport the product cases from a loading zone to a plurality of decanting stations, each decanting station having at least one container associated therewith having an amount of available space for receiving at least one product; selecting, by the control circuit, a subset of product cases from the plurality of product cases, wherein the subset comprises at least two product cases from the plurality of product cases; applying, by the control circuit, a container-packing algorithm to the subset of product cases and the containers at the decanting stations to determine a minimum number of containers needed to decant all of the products in the subset of product cases into the containers based on a projected utilization of each container, the projected utilization of each container being determined by the control circuit based on one or more dimensions of the products and an optimal packing configuration of the products when the products are stacked in the containers, wherein the optimal packing configuration is a projected packing configuration having a greatest height of the products in the container, with a maximum height being a height of the container, and a lowest area of the products in the container; assigning, by the control circuit, each product case in the subset to one of the plurality of decanting stations based on the optimal packing configurations of the products in the containers; causing, by the control circuit, the conveyor to divert each product case in the subset to its assigned decanting station; and causing the conveyor to recirculate non-selected ones of the plurality of product cases for selection into a subsequent subset of product cases.

10 . The method of claim 9 , further comprising causing, by the control circuit, a user display of each decanting station to display an instruction for packing the products from the product cases into the container.

11 . The method of claim 9 , further comprising analyzing, by the control circuit, a workload of the plurality of decanting stations to identify one or more decanting stations that can accommodate decanting.

12 . The method of claim 9 , wherein the control circuit is further configured to determine a cost function associated with diverting each product case in the subset of product cases to each decanting station and configured to cause the product cases to be diverted to assigned decanting stations based also on the cost functions.

13 . The method of claim 9 , wherein the information relating to the product cases comprises one or more of an identity of a product in the product case, a quantity of the product in the product case, one or more dimensions of the product in the product case, one or more dimensions of the product case, a weight of the product in the product case, and a weight of the product case.

14 . The method of claim 9 , wherein at least two product cases in the subset are assigned to and diverted to different decanting stations.

15 . The method of claim 9 , whe
