A recently granted patent (Publication Number: US12012292B2) discloses a product distribution conveyor system for a distribution facility. The system includes a conveyor control circuit, product feed conveyor systems, conveyor lane systems, routing systems, and sensor systems. The conveyor control circuit is responsible for controlling the movement of products along the feed conveyor and lane conveyors, ensuring products are loaded into delivery vehicles through bay doors associated with each conveyor lane system. The system also includes association rules to balance the distribution of products among retail stores by subdividing conveyor lane systems and assigning retail stores to specific lane subdivisions to minimize deviations in product volumes.

Furthermore, the system incorporates sensor systems such as bar code readers, RFID tag readers, and image processing systems to detect product identifying information. The conveyor control circuit confirms the product information, assigns products to the appropriate conveyor lane system associated with the intended retail store, and controls the movement of products based on this information. Additionally, the system includes scheduling control circuits to balance workloads of workers based on predicted lane volumes and historical data, ensuring efficient distribution of products to retail stores. Overall, the patented system offers a comprehensive solution for optimizing product distribution through a distribution conveyor system, enhancing efficiency and minimizing deviations in product volumes across different conveyor lane systems and retail stores.
