Abstract:
A hinge feeder for feeding open hinges at a predetermined orientation to a receiver ready for use by an automatic door hinger. A dispenser is provided to hold a stack of closed hinges. The orientation of the top end and hinge joint of each hinge is sensed and the hinges sequentially dispensed at a uniform orientation, except for the pinhead location, to a rotator that rotates those hinges to bring their top ends to a desired side. The hinges are then opened by a leaf turner, fed to a stacker and the opened and oriented hinges then deposited in a stack by a stacker.
