Universal head and intermediate grid for case packers

摘要

A universal head for a drop type case packer, for enabling the packer to handle a range of article sizes and arrays. Lane dividers mounted from the head define parallel lanes, the number, spacing and effective length of which can be set for desired packing conditions. Flags for signaling filling of the lanes are mounted to an adjustable end plate, and can be centered laterally according to lane width and article shape. The flags intercept a light beam between a light emitter and sensor, the alignment of which is maintained regardless of changes in lane number or dimensions.
