摘要:
An apparatus has on each side of a conveyor (12) a rotating conveying segment (16, 17) for lifting packs from the conveyor (12) to form a stack (13) of packs (11). An oscillating holding segment (18, 19) oscillates about a common axis with each conveying segment (16, 17) but at a lesser radial distance from the axis then the conveying segment. The holding segments hold the stack (13), but separate to permit a new pack (11) to be added to the bottom of the stack.
摘要:
A device for forming a stack of relatively thin articles or packages delivered in succession. The device includes a plurality of paddle wheels on opposite sides of a package delivery conveyor with individual blades of a succession thereof on each wheel positioned to underlie the margin of a package delivered by the conveyor. Upon completion of the delivery the paddle wheels are rotated or indexed in a direction to elevate the package by the underlying blades and position succeeding blades for receiving a second package. Upon further indexing movement of the paddle wheels the initial package is again elevated until the blades performing such function withdraw past the edges of the package and permit the package to drop onto the package supported by the blades therebelow. At the same time other blades of the successions are positioned to receive a third package. The operation is continued until a stack of packages of the desired number has been obtained.
