Abstract: An infeed slug loader provides for the formation of stacks or slugs of individual articles, and transfers the completed slugs to a wrapping machine. The present slug loader may be used to assemble stacks or slugs of various relatively small and flat articles, but is particularly well suited for handling food articles such as cookies, crackers, and the like. The slug loader accepts articles delivered sequentially on a delivery conveyor, and stacks them on a slope by using a turnover wheel which inserts each unit of the stack from the bottom. The use of a slope for slug assembly, obviates the need for a leading retainer for the slug at this point. The turnover wheel is mechanically linked to the infeed conveyor, with a trailing finger or pin picking up the bottom of the slug when a predetermined number of units have been stacked to form the slug. The slug is then pushed up the slope to a horizontal run, where a retractable lead finger or pin extends to hold the front end of the slug.

Abstract: A rotary manipulator for conveyor goods comprises a generally cylindrical manipulator disposed between an input or feed conveyor and one or more output conveyors, with its axis parallel to the planes of the conveyors and normal to their direction of travel. The manipulator includes at least one flattened side, with a retaining lip extending along one edge thereof. Articles such as baked goods advance along the feed conveyor, where they are captured on the flat of the manipulator and momentarily retained by the retaining lip. The manipulator is rotated to drop the articles inverted on a lower output conveyor. The next row of articles from the feed conveyor passes upright over the rounded opposite side of the manipulator, which is substantially tangent to the feed conveyor and to an upper output conveyor. The upright and inverted articles are placed in registry with one another at a point downstream.
