Automatic carton packing machine

摘要

A carton shifting device for use in an automatic carton packing machine, comprises a disc supporting a plurality of downwardly extending mandrels. The mandrels are arranged in pairs with outwardly facing surfaces lying in a common plane. A groove is defined in each outer surface of the mandrel. The paired grooves are engageable by a pair of claws connected to a withdrawing bar for movement in the downward-like direction to strip carton blanks off the mandrels. The carton blanks drop on a table where they are pushed into two rows by a pushing bar. At the end of the rows a horizontal conveyor moves to convey the carton blanks in an orderly fashion. The conveyor comprises a chain with a plurality of spaced apart rectangular blanks. The blanks are spaced apart by the carton blank length with the width of each blank being equal to two carton blank widths so that two carton blanks can be conveyed between adjacent blocks.
