Image Number 5 for United States Patent #5595442.
A tumbler loader assembly is capable of moving a container to be tumbled from a conveyor loading area into a tumbler device using a feed cart while maintaining a low cart profile. The feed cart is capable of moving the container on conveyor rollers along the feed cart as well as having the capability for movement along a guide rail from a first position where the container is loaded onto the feed cart to a second position interior of the tumbler. The tumbler device has raising and lowering capability for interengaging the feed cart as well as for positioning the container for proper tumbling. Upon loading of the container onto the feed cart, the feed cart moves along the guide rail into the tumbler. The tumbler lowers to interengage the feed cart. The feed cart then transfers the container into the tumbler and the tumbler raises to allow the feed cart to return to its starting position. The tumbler then vertically adjusts the container for proper balancing, clamps the container, and carries out the tumbling cycle. The procedure may then be reversed to remove the container from the tumbler and transfer the container back to the conveyor.
