A push sorter is a material handling system used to sort packages, parcels, or containers according to a specified criterion, such as destination, priority, or shipping method. It typically consists of a series of conveyor belts, divert stations, and sorting lanes, and it uses a mechanical or pneumatic mechanism to “push” packages onto the correct sorting lane. The packages are either scanned or manually identified, and the sorting system uses this information to determine the correct lane for each package.
