Abstract

In some embodiments, systems and methods are provided to control a product distribution conveyor system comprising: a conveyor control circuit; a product feed conveyor system; conveyor lane systems cooperated with the conveyor lane system; routing systems that cause movement of respective products from the feed conveyor system to one of the conveyor lane systems; and a plurality of sensor systems; wherein the conveyor control circuit is further configured to enhance throughput of the at least one feed conveyor system by associating each of the plurality of conveyor lane systems one of a plurality of retail stores such that a total volume of the products is substantially equally distributed over the plurality of conveyor lane systems comprising organizationally subdividing conveyor lane systems to define a plurality of lane subdivisions, and associating each retail store with a respective one of the plurality of lane subdivisions.

First claim

The invention claimed is:

1. A product distribution conveyor system of a product distribution facility, wherein the product distribution conveyor system comprises:
a conveyor control circuit;
a plurality of conveyor lane systems configured to receive one or more products of a plurality of products intended to be distributed; and
a plurality of routing systems positioned relative to one or more of the plurality of conveyor lane systems and further communicatively coupled with the conveyor control circuit;
wherein the conveyor control circuit is configured to control one or more of the plurality of routing systems in controlling movement of each of the plurality of products onto an appropriate conveyor lane system, of the plurality of conveyor lane systems; and
wherein the conveyor control circuit is further configured to control throughput comprising associating each of the plurality of conveyor lane systems with at least one of a plurality of retail stores in attempting to balance over a period of time a distribution of a total volume of the plurality of products over the plurality of conveyor lane systems comprising organizationally subdividing the plurality of conveyor lane systems to define a plurality of lane subdivisions each comprising a subsets of multiple conveyor lane systems, of the plurality of conveyor lane systems, in attempting to minimize deviations of subdivision volumes of products moved through each of the plurality of lane subdivisions.

2. The system of claim 1 , wherein each of the plurality of conveyor lane systems is controlled by the conveyor control circuit to implement movement and control of the respective conveyor lane systems to move one or more of the plurality of products along the respective conveyor lane system toward a loading area.

3. The system of claim 1 , further comprising:
a product feed conveyor system comprising a feed conveyor, wherein the product feed conveyor system is cooperated with each of the plurality of conveyor lane systems, and further communicatively coupled with and controlled by the conveyor control circuit, wherein the conveyor control circuit controls the product feed conveyor system in routing different ones of the plurality of products to an intended one of the plurality of conveyor lane systems.

4. The system of claim 3 , further comprising:
a plurality of sensor systems each positioned relative to at least one of the plurality of conveyor lane systems and/or the feed conveyor, wherein each of the plurality of sensor systems is communicatively coupled with the conveyor control circuit; and
wherein each of the plurality of sensor systems is configured to detect product identifying information of each of the plurality of products moved along the conveyor lane systems and the feed conveyor, and communicate the product identifying information of each of the plurality of products to the conveyor control circuit.

5. The system of claim 3 , wherein the conveyor control circuit is configured to:
confirm, as a first product of the plurality of products moves along the feed conveyor, first product identifying information corresponds to a scheduled product that is scheduled to be delivered to a respective intended retail store, of the plurality of retail stores, that ordered the first product;
identifies a first conveyor lane system, of the plurality of conveyor lane systems, at least temporarily associated with the respective intended retail store; and
controls a routing of the first product from the product feed conveyor system and onto the first conveyor lane system.

6. The system of claim 1 , wherein the conveyor control circuit is further configured to access retail store assignment rules and apply the retail store assignment rules to at least temporarily assign each of the plurality of retail stores to a respective conveyor lane system, of the plurality of conveyor lane systems, in attempting to minimize deviations of average lane volumes between at least pairs of neighboring conveyor lane systems of a respective subdivision.

7. The system of claim 1 , wherein the conveyor control circuit in assigning the plurality of retail stores to the respective conveyor lane system is further configured to confirm, over a threshold duration, that an average lane volume of at least three neighboring lanes is within a first lane threshold difference of an average lane volume.

8. The system of claim 1 , further comprising:
a scheduling control circuit configured to apply scheduling rules to schedule each of a plurality of workers to one or more conveyor lane systems of the plurality of conveyor lane systems as a function of assigned retail stores to the plurality of conveyor lane systems in attempting to balance workloads of the plurality of workers as a function of predicted lane volumes for a scheduled duration; and
a scheduling control circuit coupled with a database and configured to access, through the database, the total volume of products scheduled for a scheduled duration, and apply scheduling rules to schedule each of a plurality of workers to one or more conveyor lane systems of the plurality of conveyor lane systems as a function of assigned retail stores to the plurality of conveyor lane systems in attempting to balance workloads of the plurality of workers as a function of the predicted lane volumes for the scheduled duration.

9. The system of claim 1 , further comprising:
a volume prediction system configured to evaluate, for each of the plurality of retail stores, historic volumes of the plurality of products over a scheduled period and determine a predicted volume of products predicted to be distributed to a respective retail store, of the plurality of retail stores, over the scheduled period of time; and
a scheduling control circuit configured to determine a benchmark average volume per worker as a function of the total volume of the products and a total number of workers available, apply scheduling rules to evaluate different combinations of conveyor lane systems as a function of corresponding predicted lane volumes over the scheduled period of time, and assign each worker to one or more of the conveyor lane systems in attempting to minimize predicted deviations of a summation of predicted lane volumes, of the one or more conveyor lane systems to be assigned to the respective worker, from the benchmark average volume per worker.

10. The system of claim 9 , wherein the scheduling control circuit is further configured to enable access, through a user computing device, to a graphical user interface enabling entry of a number of available workers and an identifier of a distribution facility, and the scheduling control circuit is configured to access specifications for the identified distribution facility comprising at least identifiers of each of the plurality of conveyor lane systems and identifiers of each of the plurality of retail stores that are to receive one or more of the plurality of products from the identified distribution facility, and to display assignments of the workers to the respective conveyor lane systems.

11. A method of controlling product distribution through a distribution conveyor system of a product distribution facility, comprising:
causing a transport of a plurality of products to a plurality of conveyor lane systems configured to receive one or more of the plurality of products;
controlling movement of one or more of a plurality of routing systems, communicatively coupled with a conveyor control circuit, in controlling movement of each of the plurality of products by the plurality of routing systems onto an appropriate conveyor lane system of the plurality of conveyor lane systems;
controlling the plurality o
