Abstract
An alignment apparatus for aligning hairpin-shaped heat-exchanger tubes at a regular pitch. An insertion position side is configured as a regular pitch alignment unit where arrangement plates are provided at an interval that is double the pitch of through-holes in a fin stack. An upstream side is configured as a wide pitch alignment unit where arrangement plates are provided at an interval equal to an integer multiple of two or more times the regular pitch alignment unit. The regular pitch alignment unit is provided with stopper apparatuses that stop the hairpin-shaped heat-exchanger tubes at different positions in an inclined direction for the respective arrangement plates. The wide pitch alignment unit is capable of moving along an alignment direction of the arrangement plates so as to allow the hairpin-shaped heat-exchanger tubes to move to the regular pitch alignment unit, where the hairpin-shaped heat-exchanger tubes are stopped at a more downstream position.
