Abstract
A system and method for automatically processing a supply of cartons, in flattened form and of different types, in accordance with a selectable number of plural, different and separately identifiable carton types. Unsorted cartons are removed in successive layers from stacks thereof and transported in serial succession along a transport path. Sorting modules are disposed along the transport path, each including respectively associated routing and stacking devices individually predesignated to receive and stack a given, identifiable carton type. A system controller tracks the progress of each carton, simultaneously for plural cartons, along the transport path and when a match of the carton type with a predesignated stacking device is determined, actuates the associated routing device to route a carton of a matching type from the transport path and to the associated stacking device for stacking. The system controller monitors the stack content of each stacking device and, when a first matching stacking device is full, automatically routes successive cartons of the common type to an alternate and commonly predesignated stacking device, if available. One or more overflow stacking devic…
