Title: Package inspection and handling system

Abstract: A packaging handling system for detecting and rejecting faulty packages and for maintaining a packaging or boxing machine in operation for a specific period of time if one or the other goes down. The system comprises a plurality of photocell sensing units to detect the imperfectly formed packages and a means for rejecting the faulty packages. An accumulator is positioned in the conveyor line between the packaging machine and the boxer and will store a limited number of packages should the cartoning machine discontinue to operate and will feed a limited number of packages on the conveyor should the packaging machine become inoperative. When the system is utilized on a boxer being fed by two packers, a distribution table is also provided in the system to divide the work from one packer to both lines should the other packer cease to function.
