Corrugated fin feeding apparatus and feeding method

The corrugated fin feeding apparatus has cutting devices ( 1 ) producing corrugated (C 1 , C 2 ) fins with a predetermined length and a conveying device ( 2 ) determining positions of the corrugated fins and conveying them at predetermined intervals. Further, the feeding apparatus has a forcible conveying device ( 3 ) which adds a driving force to the corrugated fins being conveyed by the conveying device ( 4 ) to push out them toward the downstream side thereof and distributes them in predetermined directions, and an accumulating device which accommodates the corrugated fins into a plurality of accumulating rooms respectively. Furthermore, the feeding apparatus has an inserting device ( 5 ) which feeds a predetermined number of the corrugated fins simultaneously into a temporary assembling device ( 6 ) of a heat exchanger core when the predetermined number of them are accommodated into the accumulating rooms, and a control device ( 7 ) which synchronously controls the respective devices ( 8 ) based on the positions of the corrugated fins determined by the conveying device.
