Abstract
The machine includes a vacuum head which is mounted to rotate on the outer end of an elongated arm adapted to be pivoted upwardly and downwardly about a fixed pivot by a servo drive. As the arm pivots, the vacuum head picks either a carton blank or a tray blank out of a magazine and transfers the blank toward a conveyor. During the pivoting, the vacuum head is turned relative to the arm and, when the blank is a carton blank, the turning motion brings the blank into engagement with a fixed plow which erects the blank. During final downward movement of the arm, the vacuum head is held parallel to the conveyor and moves toward the conveyor with a vertical plunging motion. When the blank is a tray blank, such vertical plunging causes the blank to be erected by flights on the conveyor as the blank is loaded between the flights.
