Abstract
Abstract An automatic packaging machine is provided which has a chute for directing objects such as cooked french fries into the interior of a rotatable loading drum. The drum is rotated by a motor about a horizontal axis at a speed to cause the french fries to first be carried upwardly and then to fall through a predetermined path within the drum. A staging carousel is provided for carrying a supply of varying sized packaging containers such as cups. The carousel can be rotated to a dispensing position where a single selected size container will be dispensed to an index carousel. The index carousel will move the container to a position within the drum to intercept the falling french fries to fill the container. A detector is provided for sensing when the container has been filled. Once the container is filled it is moved via various transfer mechanisms to a deposit or storage area which can accommodate a plurality of containers and has a mechanism for clearing space to receive additional containers.
