The transfer device of the heat exchanger in the present embodiment has the above-described configuration. Next, a case where a plurality of heat exchangers are expanded by using the transfer device of the heat exchanger will be described.

First, as shown in FIG. 2A, while the expanded heat exchanger 6 is conveyed to be returned in one direction to the expanded tube 10 via the heat exchanger return device 4, The heat exchanger 6 for expanding the tube is placed on one of the heat exchanger mounting tables 8a which stands by while being lowered on the side of the heat exchanger supply device 2, but at this time, the heat exchanger 6 rises to the heat exchanger return device 4 side. The expanded heat exchanger 6 is mounted on the other heat exchanger mounting table 8a which stands by in the state as shown in FIG.

Next, the respective heat exchanger mounting tables 8a on which the heat exchangers 6 before and after the expansion are mounted, ascend and descend in directions opposite to each other as shown in FIG. , Arrow G).

Incidentally, on the upper surface of the heat exchanger mounting table 8a,
Since a plurality of transfer rollers 8b capable of sending out the mounted heat exchanger 6 to the tube expanding device 10 are arranged in parallel, the heat exchanger mounting table 8a moves up and down in opposite directions as described above. At the time when (arrows F and G) are completed, the heat exchanger 6 mounted on one of the heat exchanger mounting tables 8a which stands by while being raised on the heat exchanger supply device 2 side is shown in FIG. As shown in (1), it is sent out to the transportable position of the heat exchanger supply device 2 via the transfer roller 8b.

Therefore, as described above, the heat exchanger 6 placed on the supply conveyor 2a of the heat exchanger supply device 2 constituting the transfer device 1 is, as shown in FIG. Through simultaneous movement of the heat exchanger holding device 7a of the heat exchanger guiding and transferring device 7, it is conveyed from one direction to the expansion device 10 (arrow B) and transferred to the turntable 3a of the heat exchanger take-out device 3.
