Estimating the term…
An improved magazine particularly useful for stacking concentrated or superconcentrated detergent cartons and a process for erecting such cartons and other stackable items. Manufacturing problems resulting from the presence of the handle in high density powder cartons can be reduced by use of a magazine or chute having curved side walls, which accommodate the fanning which normally occurs when the cartons are stacked. Flat tubular carton blanks are inserted, preferably horizontally, into a first carton opening in the magazine and travel therethrough to a second, preferably vertical opening in the magazine, where they emerge. The shape of the magazine accommodates the uneven stacking of the cartons which tends to occur because of the extra localized thickness contributed by the carton handle and the rivets. A case turner is provided for feeding cases of cartons into the magazine.
A magazine in combination with a plurality of flattened tubular cartons having a localized increase in thickness leading to an imbalanced stack, loaded in said magazine, said magazine comprising a first side wall, a second side wall on the side opposite said first, side wall, front carbon motion restraining means and rear carton motion restraining means limiting the movement of said carton in directions parallel to said sidewalls, said sidewalls extending curvedly from a first carton open end bounded on its periphery by said first and second sidewalls and said front and rear carton motion restraining means to a second carton open end defined by said first and second sidewalls and said front and rear carton restraining means, said curvature extending continuously from said first to said second open end so as to accommodate the unbalanced stack of cartons.
A magazine in combination with a plurality of flattened tubular cartons having a localized increase in thickness leading to an imbalanced stack, loaded in said magazine said magazine comprising a first side wall, a second side wall on the side opposite said first side wall, front carton motion restraining means and rear carton motion restraining means limiting the movement of said carton in directions parallel to said sidewalls, at least one of said front and rear carton motion restraining means not extending uninterruptedly between said first and second sidewalls, said sidewalls extending curvedly from a first carton open end bounded on its periphery by said first and second sidewalls and said front and rear carton motion restraining means to a second carton open end defined by said first end second sidewalls and said front and rear carton restraining means, said curvature extending continuously from said first to said second open end so as to accommodate the unbalanced stack of cartons.
The combined magazine and cartons of claim 6 wherein the clearance between the edges of the tubular carton and the sidewalls and front and rear restraining means of said magazine is at no point greater than 1/2 inch.
A process of feeding a plurality of cartons having a localized increase in thickness leading to an unbalanced stack comprising conveying folded, flat, tubular carton blanks into a first open end of a magazine having curved sidewalls and front and rear carton motion restraining means limiting the movement of said cartons in directions parallel to said sidewalls and conveying said folded, flattened tubular carton blanks along a continuously curved path corresponding to the natural fanning of the cartons through a second open end in said magazine said first open end lying in a first plane and said second open end lying in a second plane, the first plane being disposed at an angle different from the second plane, said curved path accomodating the unbalanced stack of cartons.
A magazine for receiving flattened cartons comprising a first side wall, a second side wall on the side opposite said first side wall, front carton motion restraining means and rear carton motion restraining means limiting the movement of said carton in directions parallel to said sidewalls, said sidewalls extending in a continuous curve from a first open end bounded on its periphery by said first and second sidewalls and said front and rear carton motion restraining means to a second open end defined by said first and second sidewalls and said front and rear carton restraining means, one of said side walls extending below the other, and a belt traversing the inside of the lower of said curved sidewalls and movable with respect thereto, said inside of the lower sidewall forming a concave curve.
