ABSTRACT:
An apparatus for removing cartons from a stack of cartons arranged in horizontal layers with pairs of cartons in each layer arranged in perpendicular relatonship with adjacent pairs includes first gripping means for lifting a layer of cartons from the stack and separating cartons in the layer into two groupings and second gripping means adapted to grip each grouping of cartons and further separate cartons in the grouping for deposition at a spaced location. The second gripping means consists of reciprocating heads at least one of which is adapted to pivot about a vertical axis so as to reorient selected cartons so that the cartons can be deposited at the spaced location in parallel relationship. Further, the second gripping means are pivotal about a horizontal axis so as to be swingable into an out of the way position to allow another of the second gripping means to move along a preselected path from the first gripping means to the spaced location. The method of the invention includes the steps grasping with the first gripping means a plurality of cartons or the like arranged in a common horizontal plane, lifting the grasped cartons, separating the lifted cartons while they are grasped, grasping the separated cartons with second gripping means, releasing the cartons from the first gripping means, and transferring the cartons with the second gripping means to a spaced location.
