DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchange fin assembly in which only a conduit is inserted through a fin laminate, and a heat exchange fin assembly which can be turned upside down and automatically stored in a predetermined receiving jig. The present invention relates to a transfer device for a replacement fin assembly semi-finished product.

[0002]

2. Description of the Related Art FIG. 19 shows an example 1 of a heat exchange fin assembly used for a cooling / heating machine or the like. The heat exchange fin assembly 1 includes a fin laminate 5 formed by laminating a large number of thin metal plate fins 3, a plurality of hairpin-shaped conduits 7 skewed through the fin laminate 5, and a fin. Side plate 11 superimposed on the laminate 5 from the tip 9 side of the conduit 7
And a U-shaped return bend 13 to which the distal end 9 of the conduit 7 is connected. The return bend 13 is welded so that a large number of conduits 7 are continuously connected.

[0003] The assembly work of the heat exchange fin assembly 1 is usually performed in the following order. First, after a necessary number of fins 3 are stacked on an appropriate jig, the conduit 7 is inserted into an insertion hole 15 formed in the fin 3. Thus, a heat exchange fin assembly semi-finished product 17 is configured. Next, the heat exchange fin assembly semi-finished product 17 is turned upside down and supported by another jig. Then, after stacking the side plates 11,
After performing the pipe expansion process of expanding the diameter of the conduit 7 and bringing it into close contact with the fin 3, the return bend 13 is welded.

In the above-described assembling operation, the reason why the heat-exchange fin assembly semi-finished product 17 is turned upside down when the heat-exchange fin assembly semi-finished product 17 is constructed is that the work direction and work space specific to each operation are limited. This depends on restrictions and the like. That is,
If the operation of inserting the conduit 7 into the fin laminate 5 is performed from below, not only is the workability poor, but also a considerably deep pit must be dug on the floor of the factory. Further, it is practically impossible to overlap the side plates 11 or to perform the pipe expansion and the return bend 13 welding work from below.

[0005]

Therefore, in this type of assembling operation, a step of inverting the heat-exchange fin assembly semi-finished product 17 is required, but the heat-exchange fin assembly semi-finished product 17 is simply turned upside down. In this case, since the conduit 7 falls off from the fin laminate 5, the operation for this reversal has conventionally been performed manually. For this reason, there has been a problem that work efficiency is poor and involves many dangers.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and a required jig is obtained by mechanically inverting a heat exchange fin assembly semi-finished product without a pipe falling off from a fin laminate.
