  • Patent number: 4917229
    Abstract: A method and apparatus for stacking products such as trays are disclosed utilizing a rotary ferris wheel device which raises product off a conveyor and places it on a platform where it is pushed off unto additional product being conveyed on the conveyor. Specifically, an arm is rotated from a noninterfering position below the conveyor until a pivotally mounted shoe on the free end of the arm abuts the product without gripping or attachment thereto, raises the product off the conveyor, and places the product on a platform. The next product on the conveyor is allowed to be conveyed on the conveyor without interference. After the arm is rotated from under the platform into a noninterfering position below the conveyor, the product is pushed off the platform unto the product which remained on the conveyor. Thereafter, the stacked products continue to be conveyed on the conveyor.
