  • Patent number: 11911797
    Abstract: Systems, methods, and computer-readable media are disclosed for multi-path sorting systems that facilitate package sorting for delivery and near-real time changes to sortation for rerouting of the packages. The package sorting system may include conventional conveyor systems that deliver packages to multi-path conveyors (e.g., multi-path conveyor belts) that may cause the package to be moved in multiple directions to ultimately deposit a package onto an output conveyor system for delivery to a downstream location (e.g., packaging station, sorting station, etc.). The input conveyors may include a sensor for determining information about the package (e.g., destination address, order information, etc.) which may be used to determine the optimal downstream route for the package, which may be adjusted as conditions change.
