The heat exchanger holding device 7a of the heat exchanger guide and transfer device 7 has the same moving speed as that of the conveyors 2a and 4a of the heat exchanger supply device 2 and the heat exchanger return device 4, respectively. By holding the heat exchanger 6 at a predetermined speed and moving it by a predetermined distance, and further, after moving the predetermined distance, the held heat exchanger 6 is opened and returned, and the heat exchanger 6 is held and moved again. The heat exchanger 6 on the supply conveyor 2a of the heat exchanger supply device 2 is transferred onto the turntable 3a of the heat exchanger extraction device 3, and the expanded heat exchanger 6 is discharged from the heat exchanger return device 4. It can be transferred onto the conveyor 4a.

Further, at one end side of each of the heat exchanger supply device 2 and the heat exchanger return device 4, a heat exchanger 6 before pipe expansion mounted on a heat exchanger mounting table 8a is provided. The heat exchanger supply device 2 is moved up to the transportable position of the supply device 2.
There is provided a mounting table elevating device 8 which is placed on the heat exchanger mounting table 8a and lowered to transfer the heat exchanger 6 after being expanded to the heat exchanger returning device 4 from the heat exchanger returning device 4.

It should be noted that the mounting table elevating / lowering device 8 shown in FIG.
As shown in (a), a pair of heat exchanger mounting bases 8a corresponding to the heat exchanger supply device 2 and the heat exchanger return device 4, respectively.
And the pair of heat exchanger mounting bases 8a are moved up and down in the directions opposite to each other (arrow F,
As shown in FIG. 3B, each of the heat exchanger mounting bases 8a is configured to repeat the arrow G). The configuration is such that it moves horizontally between the exchanger supply device 2 and the heat exchanger return device 4 (arrows H and I).

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

First, as shown in FIG. 2 (a), while the heat exchanger 6 after pipe expansion is conveyed so as to be returned to one direction of the pipe expansion device 10 via the heat exchanger return device 4. The heat exchanger 6 for expanding the pipe is placed on the one heat exchanger mounting table 8a which stands by in the lowered state on the heat exchanger supply device 2 side, but at this time, it is raised to the heat exchanger return device 4 side. The heat exchanger 6 after the pipe expansion is mounted on the other heat exchanger mounting table 8a that stands by in this state, as shown in FIG.

Next, the heat exchanger mounting bases 8a on which the heat exchangers 6 before and after pipe expansion are mounted are moved up and down in opposite directions (arrow F) as shown in FIG. , Arrow G).

In addition, on the upper surface of the heat exchanger mounting table 8a,
Since a plurality of transfer rollers 8b capable of sending out the placed heat exchanger 6 to the tube expanding device 10 side are arranged in parallel, the heat exchanger placing table 8a ascends and descends in the opposite directions as described above. The heat exchanger 6 mounted on the one heat exchanger mounting table 8a that stands by in the state where the heat exchanger supply device 2 has risen when (arrow F, arrow G) is finished is shown in FIG. As shown in FIG. 5, the heat exchanger is supplied to 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 which constitutes the carrier device 1 has the supply conveyors 2a and 2a as shown in FIG. Through the simultaneous movement of the heat exchanger holding device 7a of the heat exchanger guide and transfer device 7, it is conveyed from one direction to the pipe expanding device 10 (arrow B), and is also transferred onto the turntable 3a of the heat exchanger extraction device 3. Will be done.

Next, the heat exchanger 6 transferred onto the turntable 3a of the heat exchanger take-out device 3 has the turntable 3a.
The tube is fixed on the turntable 3a via the heat exchanger fixing device 3c provided on the tube and expanded by the reciprocating body 11 provided on the tube expanding device 10.

After that, the heat exchanger 6 expanded on the turntable 3a is expanded in the expandable region of the expansion device 10 through the rotation (arrow C) of the turntable 3a as shown in FIG. It will be transferred so that it can be separated more.

The holding body 7b of the heat exchanger holding device 7a which holds the heat exchanger 6 while the turntable 3a rotates (arrow C) as described above operates so as to open the heat exchanger 6. Will be done.

Therefore, as shown in FIG. 4, the heat exchanger 6 separated from the expandable region of the expander 10 by the rotation of the turntable 3a as described above, is connected to the return conveyor 4a of the heat exchanger return device 4 and the heat exchanger 4a. Through the simultaneous movement of the heat exchanger holding device 7a of the exchanger guide and transfer device 7, the heat exchanger holding device 7a is conveyed (arrow D) from the turntable 3a so as to be returned to the one direction of the tube expanding device 10 again.

Incidentally, the heat exchanger 6 conveyed to be returned to the mounting table elevating device 8 side via the return conveyor 4a of the heat exchanger returning device 4 as described above is shown in FIG. Similarly, in order to switch the positions of each other, it moves horizontally between the heat exchanger supply device 2 and the heat exchanger return device 4 (arrow H,
By carrying out the arrow I), it is mounted on the one heat exchanger mounting table 8a that has moved to the heat exchanger returning device 4 side.

Therefore, the other heat exchanger mounting table 8a which is horizontally moved between the heat exchanger supply device 2 and the heat exchanger return device 4 in order to exchange the positions of the other, is shown in FIG. As shown in (1), the heat exchanger 6 after pipe expansion is placed in a mounted state and stands by in the lowered state on the heat exchanger supply device 2 side.

Therefore, the operator can easily and instantly take out the heat exchanger 6 after tube expansion from the heat exchanger mounting table 8a (arrow J) without forcing an unreasonable posture. .

Not only can it be placed on the heat exchanger mounting table 8a stopped at the position and sequentially supplied to the tube expansion device 10, but the heat exchanger 6 after tube expansion is lower than the transportable position of the heat exchanger return device 4. Either the heat exchanger supply device 2 or the heat exchanger return device 4 located in one direction of the tube expansion device 10 can be easily taken out from the heat exchanger mounting table 8a stopped at the position. By concentrating on only one end side, it eliminates all the problems such as a series of time loss related to transportation time and the extra personnel involved in the labor force for that, and personnel expenses related to the personnel, The heat exchanger transfer and tube expansion processes are integrated.

It is possible to dramatically increase the number of pipes to be expanded, but at this time, the reciprocating body of the pipe expansion device has a number of pipe expansion mandrels corresponding to the pipes of the heat exchanger conveyed in parallel. It goes without saying that it is provided.

The heat exchanger pedestal holds the heat exchanger in an upright position. However, a receiver for holding the heat exchanger by inserting the end portion of the tube inserted into the heat exchanger is used. It may be provided, and in this case, the heat exchanger can be erected and held in a stable state, but the specific shape of the heat exchanger pedestal, the holding mechanism of the heat exchanger, etc. It goes without saying that not only the structure but also the presence or absence of the heat exchanger pedestal is not limited.
