Continuous motion cartoner assembly

A continuous motion cartoner assembly for loading article groups into the open ends of cartons being moved on a conveyor comprising:

• a) a frame structuring having an elongated, horizontal working area, two pairs of longitudinally oriented carton drive chains, a pair of longitudinally oriented article drive chains parallel said carton drive chains and synchronized means to drive said chains;
• b) a continuous cam rail structure longitudinally mounted to said frame structure and having transverse inwardly and outwardly sloping sections;
• c) a plurality of carton lugs connected to each said pair of carton drive chains and spaced at predetermined intervals;
• d) a plurality of transversely oriented, fixed article transfer flights connected between said article drive chains;
• e) an article infeed conveyor disposed angularly with respect to said article transfer flights to provide a continuous stream of articles for pickup by said article transfer flights;
• f) a carton transfer device for placing open ended cartons between said carton lugs;
• and
• g) a plurality of longitudinally conveyed article group transfer structures, one said transfer structure being operative between adjacent article transfer flights and being constructed and arranged to transversely move article groups into the opened end of the cartons.

An adjustable cartoner assembly for loading article groups into open carton sleeves comprising:

• a) an adjustable article infeed conveyor having a plurality of parallel guide structures fixed thereabove, said article infeed conveyor supplying a first stream of articles, said guide structures having adjustment means constructed and arranged to adjust the number of article streams;
• b) an adjustable article selecting conveyor having a plurality of spaced, parallel and transversely oriented fixed flight bars and a longitudinal travel path disposed adjacent to and parallel with said article infeed conveyor, said flight bars intersecting said article infeed guide structures at a predetermined angle to form and move a second longitudinal stream of article groups of a predetermined angle to form and move a second longitudinal stream of article groups of a predetermined pattern, said flight bars being constructed and arranged to select a predetermined pattern or article groups;
• c) an adjustable carton supply conveyor having spaced carton flight lugs synchronized and moving adjacent to and parallel with said article selecting conveyor to provide a third longitudinal stream of cartons with open ends facing said moving article groups;
• d) adjustable article group transfer means for moving article groups into the open ends of the carton sleeves, said article group transfer means comprising guide support means longitudinally moving in parallel synchronization with said carton supply conveyor, a plurality of transversely operative, longitudinally moving pushing mechanisms, and activation means to transversely move said pushing mechanism at predetermined longitudinal positions;
• and
• e) article funnel means movable between said carton supply conveyor and said article group transfer means and being constructed and arranged to guide said article groups into the cartons and to maintain carton flap position as said transfer means is operative.

A cartoner assembly for loading article groups into open carton sleeves comprising:

• a) article infeed means supplying at least one stream of articles;
• b) article selecting means intersecting said article infeed means to form and move a longitudinal stream of article groups of a predetermined pattern;
• c) carton supply means synchronized and moving parallel with said article selecting means to provide cartons with open ends facing said moving article groups, said carton supply means comprising a plurality of spaced, transversely and longitudinally adjustable carton flight lugs arranged in groups of at least two, at lest one said lug leading each carton and at least one said lug pair trailing each carton, said carton supply means further comprising two pairs of driven endless chains having spaced connecting means attaching said lugs, and drive means including a first drive shaft having at least one trailing sprocket and at least one leading sprocket and a second drive shaft, said leading sprocket being driven by said first drive shaft, said trailing sprocket being mounted on bushings so that they freely rotate about said first drive shaft and are driven by said second drive shaft in synchronization with said first drive shaft;
• and
• d) article group transfer means constructed and arranged to move article groups into the open ends of the carton sleeves.

A cartoner assembly for loading article groups into open carton sleeves comprising:

• a) article infeed means supplying at least one stream of articles;
• b) article selecting means intersecting said article infeed means to form and move a longitudinal stream of article groups of a predetermined pattern;
• c) carton supply means synchronized and moving parallel with said article selecting means to provide cartons with open ends facing said moving article groups;
• and
• d) article group transfer means constructed and arranged to move article groups into the open ends of the carton sleeves, said article group transfer means comprising guide support means moving in parallel synchronization with said carton supply means, a movable pushing mechanism operative in a transverse direction, and a cam track/cam follower assembly to move said pushing mechanism at predetermined positions during its travel path, said pushing mechanism including a movable head member, cam activatable at predetermined times with respect to said travel path and a pivotable member connected to said movable head member and having a cam follower acted upon by said cam track/cam follower assembly.
