Hereinafter, an embodiment of the end plate setting device 100 for a heat exchanger according to the present invention will be specifically described with reference to the drawings. As shown in FIGS. 1 to 4, the end plate setting device 100 for a heat exchanger in the present embodiment horizontally connects and detaches the end plate mounting body 10, the guide pin holding body 20, and the refrigerant pipe holding portion 30. It includes a moving means 40 and a horizontal moving unit 50, a height moving means 60 and a height moving unit 70, and an operation control unit 80 that controls their movements.

It can be divided into three parts.

Next, the end plate mounting portion 90 will be described. The end plate mounting portion 90 is connected to the height direction moving portion 70 via a mounting adapter 72. The mounting adapter 72 is a part of the first adapter 72A that connects the end plate mounting portion 90 to the telescopic rod of the fluid cylinder 70A that is a part of the height direction moving portion 70, and a part of the height direction moving portion 70. It has a second adapter 72B for connecting the end plate mounting portion 90 to the guide rod 70B. The lower end portion of the guide rod 70B is connected by the connecting member 70C, and the guide rods 70B are maintained so as to be always parallel to each other.

Further, the end plate mounting portion 90 is connected to the horizontal moving portion 50 via the horizontal base 73 together with the height direction moving portion 70. A main body of the fluid cylinder 70A and a sleeve 70D through which the guide rod 70B is inserted are fixed to the horizontal base 73, respectively.

An end plate support 16 which is formed so as to be equal to or smaller than the inner diameter of the through hole 12A and is inserted into the through hole 12A and can be projected from the upper surface of the bottom plate 12 may be provided. When the end plate support 16 is moved in the height direction, it can be realized by the expansion / contraction operation of the end plate support fluid cylinder 18 attached to the end plate mounting body 10. The expansion and contraction of the end plate support fluid cylinder 18 is controlled by the operation control unit 80 based on an operation control program stored in a storage unit (not shown). As such an operation control unit 80, a central processing unit called a so-called CPU can be preferably used.

The end plate mounting body 10 and the guide pin holding body 20 in the present embodiment can be separated from each other by the horizontal contact / disengagement means 40.

As shown in FIG. 2, the refrigerant pipe holding portion 30 in the present embodiment has two holding bodies 32 that hold the refrigerant pipe 31 at two locations in the longitudinal direction. Each of these two holding bodies 32 is provided so as to be movable in the horizontal direction in a state independent of the end plate mounting portion 90 by a horizontal moving mechanism (not shown). In the refrigerant pipe holding unit 30 of the present embodiment, the refrigerant pipe 31 is appropriately supplied by a loader (not shown) whose operation is controlled by the operation control unit 80. By adopting such a configuration of the refrigerant pipe holding portion 30, the refrigerant pipe holding portion 30 can be brought into contact with and separated from the guide pin holding body 20. The refrigerant pipe holding portion 30 may be fixed, and the guide pin holding body 20 may be moved in contact with the refrigerant pipe holding portion 30 by driving the horizontal contact / disengagement means 40 or the horizontal moving portion 50. ..

The process of changing the relative height position with and to retract the end plate mounting portion 90 below the refrigerant pipe holding portion 30 (step 9) is executed. In this way, the refrigerant pipe 31 to which the end plate T is mounted is separated from the end plate mounting portion 90 in the horizontal direction together with the refrigerant pipe holding portion 30 by operating the horizontal movement mechanism (not shown) by the operation control unit 80, and then It will be sent to the process of (step 10).
