Disclosed is an automated method to hold, position, and release disk process cassettes and shipping containers while using a disk lifter tool mounted under a conveyor. The disk lifters are designed for standalone use and not designed to be mounted on a conveyor. The invention is a spring-loaded lever arm that automatically catches and securely holds the leading edge of the process cassette or shipping container as it travels on the conveyor system. The lever arm is mounted on the disk lifter tool and allows full use of the disk lifter including proper positioning of the process cassette or shipping container and does not intervere with disk lifting. The lever arm automatically releases the process cassette or shipping container when the stage has moved beyond the last disk slot of the process cassette or shipping container. This allows the process cassette or shipping container to continue travel on the conveyor system. As shown in the figure, the cassette is held in place by the lever arm (01) so disks can be removed/replaced from the cassette by the disk lifter. Past the point where the last disk is accessible by the disk lifter, the lever arm (01) can contact the release slide (03) which is on an adjustable mounting plate (04). When the lever arm (01) contacts the bevel on the release slide (03), the lever arm drops into the mounting base (02) and the cassette is released.
