Abstract

A door assembly apparatus comprises a table having a top frame and a controllably driven lift frame supported immediately beneath the top frame to support a first door component, such as an insert, adjacent to the top frame for insertion into an associated opening in the main body of the door that has been placed upon the top frame and is captured by a workpiece member capture and manipulation unit. The workpiece grasping and manipulation unit is mounted adjacent to opposite ends of the table to grasp and manipulate the orientation of the main body relative to the door insert, to join the door components together into an assembled door. To facilitate removal of the assembled door from the table, a controllably tiltable frame is arranged to receive the assembled door from the top frame and controllably tilt the assembled door away from the top frame. The workpiece grasping and manipulation unit comprises first and second rack and pinion driven elevator mechanisms, which controllably elevate the main body of the door member above the door insert as retained by the lift frame, and provide for rotation of the elevated main body of the door. The workpiece grasping and manipulation unit includes a pinion drive unit having a drive shaft that is coupled to the pinions of each rack and pinion elevator mechanism.
