  • Patent number: 5131899
    Abstract: A magazine for holding a plurality of articles, such as cartons, which are to be singularly withdrawn at a downstream end, and a method of feeding articles. The magazine includes guides, spaced apart by a distance greater than the width of the cartons in their folded condition, thereby creating a gap between an inner guide surface and one of the edges of the cartons. A pair of stoppers oppositely project toward each other and are spaced apart by a distance less than the width of the cartons, to thereby hold the most downstream carton in a position to facilitate its withdrawal at the discharge end of the magazine. The stoppers are positioned to engage the particular edges of the cartons of which the distance between them is not apt to be variable, to thereby reduce the likelihood of the cartons becoming jammed within the magazine. At least one feed roller projects from one inner guide surface toward the other inner guide surface upstream of the discharge end.

A feed roller projects from one inner guide surface toward the other inner guide surface upstream of the discharge end. At least one carton is engaged between the roller and the other inner guide surface to isolate a predetermined number of folded cartons downstream of the feed roller from a second predetermined quantity of folded cartons upstream of the feed roller.

  • Patent number: 4983154
    Abstract: Disclosed are carton assembling method and equipment for sucking and taking out flatwise folded cartons one by one from a magazine by means of suction cups, unfolding each carton squarely on a conveyance path while transferring it downward along a rotative path, and supplying the thus-unfolded cartons to an encasing machine by means of a conveyance mechanism. Each carton is held squarely by a pair of stoppers, utilizing its reaction force acting in the returning direction. Thereafter, the carton is reverse-folded against such reaction force and then unfolded again to remove the folding tendency of the carton acting in the folded direction, thereby permitting the carton to hold itself in a square shape. And at the time of reverse folding, the flaps of each carton are expanded so that a contents charging conveyor can be disposed in close proximity to the cartons.
