CARTON FOLDING APPARATUS

摘要

A carton folding apparatus which is characterized by multiple folder/gluer modules, including a feed module for receiving and delivering unfolded cartons, prefold/fold, fold and final fold modules for effecting specified folding and gluing operations, a delivery module for completing the folding operations and further including a stacker unit for receiving and stacking the folded and glued cartons. Each of the folder/gluer modules is capable of being removed from the apparatus line and is characterized by separate, independently driven upper and lower belt feed mechanisms for driving the cartons through that module. The feed module includes adjustable upper and lower feed assemblies and the remaining prefold/fold, fold, delivery and final fold modules include upper and lower carriages, which upper carriages may be adjusted upwardly with respect to the feed assembly and bottom carriages, respectively, and both carriages in the prefold/fold, fold, delivery and final fold modules are laterally adjustable to accommodate cartons of various width. While the respective belts in each of the folder/gluer modules are independently driven, all belt drive motors are synchronized to insure that the belts operate at the same speed. The belt-carrying mechanisms in all of the folder/gluer modules are designed to facilitate optimum belt replacement without the necessity of dismantling the carrying mechanisms.
