<p>A carton feeding and erecting mechanism for a machine for packaging articles such as beverage containers (c) into cartons (ct) includes a carton conveyor (16, 18) for conveying an open-ended carton (ct) through the machine. The feeding and erecting mechanism includes a vacuum conveyor (42a, 44a) for engaging a lower surface of a collapsed carton (ct) and moving the carton (ct) onto the carton conveyor (16, 18), and a feeder (40) beneath the vacuum conveyor (42a, 44a) for selecting a collapsed carton (ct) from a carton supply (10) and placing the carton (ct) on the vacuum conveyor (42a, 44a). An erector (46) above the vacuum conveyor (42a, 44a) has vacuum cups (46a) for engaging an upper surface of the collapsed carton (ct) and moving the panel upwardly with respect to the lower surface thereby erecting the carton (ct). A series of upper carton engaging elements (481) above and synchronously moving with the vacuum conveyor (42a, 44a) engages the erected carton (ct) to maintain the carton (ct) in erected condition until moved onto the carton conveyor (16, 18).</p> |
