Apparatus for conveying molded body for heat exchanger fins

An apparatus for conveying a molded body for heat exchanger fins that conveys, when manufacturing heat exchanger fins in which through-holes into which heat exchanger tubes are inserted or cutaway portions into which flattened tubes for heat exchanging are inserted are formed, a molded body for heat exchanger fins in a predetermined direction at a stage after formation of the through-holes or the cutaway portions in a thin metal plate but before cutting into predetermined lengths in a conveying direction,

• the apparatus comprising:
• a plurality of conveying units that are disposed along the conveying direction of the molded body for heat exchanger fins and each include
• a rotating conveyor that has a plurality of tapered protrusions that are capable of advancing into the through-holes or the cutaway portions and has a rotating shaft in a direction that is perpendicular, on a horizontal plane, to the conveying direction of the molded body for heat exchanger fins, and
• a rotating conveyor driving unit that rotationally drives the rotating conveyor about the rotating shaft;
• and
• an operation control unit that controls the plurality of rotating conveyor driving units so as to synchronize rotational speeds between the plurality of conveying units,
• wherein in conveying units that are adjacent in the conveying direction of the molded body for heat exchanger fins, the rotating conveyor driving units are disposed at alternating positions in a direction that is perpendicular on the horizontal plane to the conveying direction of the molded body for heat exchanger fins, and
• for rotating conveyors that are adjacent in the conveying direction of the molded body for heat exchanger fins, a power transmitting body is suspended between one end of one rotating conveyor and another end of another rotating conveyor.
