Abstract: A parts feeding system (14) for moving parts (10) relative to a support plane (12) is provided. A robot (16) having a base (18) is disposed on the support plane (12) and operable within an envelope (22) having a limit (24) that extends at an acute angle (B) relative to the support plane (12). First and second part support trays (42,44) are stacked one above the other to support the parts (10) thereon in a stacked position (48). The second part support tray (44) is movable to a stored position (50) which uncovers the first part support tray (42) immediately therebelow. Each of the part support trays (30) includes a front edge (34) facing toward the base (18) in the stacked position (48). The front edge (34) of each of the part support trays (30) is disposed a greater distance from the base (18) than the part support tray (30) therebelow to define a receding stacked relationship.

Abstract: A moving part has material initially applied to it a predetermined distance from its leading edge. Whenever a sensor senses a notch in a flange of the moving part, application of material to the moving part is stopped for a predetermined distance prior to the start of the notch to a predetermined distance beyond the notch. Application of material to the moving part is finally stopped a predetermined distance prior to its trailing edge. Two separate sensors are used to control each of three spray guns for applying the material in the selected areas.
