This machine is used to assemble the top portion of a toilet valve assembly.  The valve top assembly consists of 6 parts.  The heart of the machine is a Ferguson overhead tool plate indexing chassis.  The overhead tool plate strokes up and down twice each cycle making a short and a long stroke.  The short stroke occurs while the turret is indexing and is used to pick up parts.  Each station that needs to can make use of this cam operated vertical motion for parts placing and probing functions.  All stations that load parts use ADAPT standard pneumatic tool plate slides mounted on the overhead tool plate to provide the horizontal motion required to pick and place the parts into the turret fixture.  After each loading operation, the presence of the part is verified by the machine.
