Abstract
Techniques are disclosed for remotely switching screw color or screw type feeding into a door assembly machine with an auto-hinge applicator. An apparatus having a turntable is supported on bearings and a framework. Each side of the turntable includes a screw hopper accessible via a rotary index. The screw hoppers receive a user input to make a screw selection. Upon receiving a selection, one of the hoppers indexes into position, allowing the correct screw to feed to the hinge applicator. Screw feed-hoses from screwdrivers on the hinge applicator are arranged to connect to a manifold below the screw hoppers. Screws drop from the hoppers into a manifold, at which point the screws are blown with compressed air through the feed-hoses to the screwdrivers on the hinge applicator. Screws can be reloaded into the screw hoppers when rotated in alignment with the hinge side of the door assembly machine.
