Such heat exchangers are fixed to the mounting object using parts called end plates (or tube sheets). A configuration of a heat exchanger to which such end plates are attached is known, for example, as disclosed in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2017-96505).

Japanese Patent Application Laid-Open No. 2017-96505 (specification paragraphs 0016-0023, FIGS. 1 to 4, etc.)

Patent Document 1 discloses that an end plate is used to connect a plurality of heat exchange parts, but how is such an end plate attached to the heat exchanger? has not been disclosed. When attaching the end plate to the refrigerant pipes of the heat exchanger manually, it is necessary to align the positions of the refrigerant pipe insertion holes formed in the end plate with respect to the plurality of refrigerant pipes.

The end plate setting device for a heat exchanger is characterized in that it is set on the refrigerant pipe that has been formed.

As a result, the end plates can be automatically set to the refrigerant pipes before the heat exchanger is assembled (before the heat radiation fins are laminated). Also, the end plate can be automatically set to the refrigerant pipe even after the heat radiation fins are laminated along the refrigerant pipe.

In addition, the end plate used when attaching the heat exchanger in which the refrigerant pipes are inserted through the laminated heat radiation fins to the mounting object is placed at the position of the refrigerant pipe insertion hole formed in the end plate. A heat exchanger end plate setting device for setting to the refrigerant pipe, comprising: a refrigerant pipe holding portion for holding the refrigerant pipe; and an axial direction of the refrigerant pipe in which the end plate is held by the refrigerant pipe holding portion. and a guide pin that can be inserted into the refrigerant pipe insertion hole of the end plate mounted on the end plate mounting body. a guide pin holder that holds the end plate holder and the guide pin holder, a height direction moving means that can change the relative height position between at least the end plate holder and the guide pin holder, and the end plate holder and the guide pin a horizontal contact/separation movement means for moving the holder in the horizontal direction; a horizontal movement portion; a height direction movement portion for moving at least one of the refrigerant pipe holding portion and the end plate mounting portion in a height direction; and at least the height direction movement means and the horizontal movement means. and an operation control unit that controls the operations of the horizontal movement unit and the height direction movement unit, and the operation control unit operates the height direction movement unit to move the end plate placing unit and a process of aligning the height position of the refrigerant pipe holding portion; a process of inserting the guide pin into the refrigerant pipe insertion hole of the end plate by bringing the guide pin holder closer to the guide pin holder; A process of inserting the end plate, which is inserted into the tip of the pipe and passed through the guide pin, into the refrigerant pipe at the position of the refrigerant pipe insertion hole, and operating the height direction moving means to mount the end plate. a process of varying the relative height positions of the placement body and the guide pin holder; a process of actuating the horizontal movement section to separate the guide pin holder and the refrigerant pipe holder; A process of actuating the directional moving part to make the height position of the end plate mounting part and the height position of the refrigerant pipe holding part different; and a process of horizontally separating the refrigerant pipe holding portion on which the end plate is set and the end plate mounting portion.

As a result, the end plates can be automatically set to the refrigerant pipes before the heat exchanger is assembled (before the heat radiation fins are laminated). Also, the end plate can be automatically set to the refrigerant pipe even after the heat radiation fins are laminated along the refrigerant pipe. Then, the refrigerant pipes or heat exchangers to which the end plates are attached can be automatically sent to the next process, making it possible to continuously manufacture heat exchangers.

An embodiment of a heat exchanger end plate setting device 100 according to the present invention will be specifically described below with reference to the drawings. As shown in FIGS. 1 to 4, the heat exchanger end plate setting device 100 according to the present embodiment includes an end plate mounting body 10, a guide pin holder 20, a refrigerant pipe holder 30, and a horizontal direction contact and separation. It comprises moving means 40 and horizontal direction moving section 50, height direction moving means 60 and height direction moving section 70, and motion control section 80 for controlling these motions. The heat exchanger end plate setting device 100 according to the present embodiment includes the end plate mounting member 10, the guide pin holder 20, the refrigerant pipe holder 30, the horizontal contact/separation movement means 40, and the height direction movement means 40. An end plate placing portion 90 having means 60, a height direction moving portion 70 for moving the end plate placing portion 90 in the height direction, and a horizontal direction moving portion 50 for horizontally moving the end plate placing portion 90. can be divided into three parts.

Next, the end plate mounting portion 90 will be described. The end plate mounting section 90 is connected to the height direction moving section 70 via the mounting adapter 72 . This mounting adapter 72 is a first adapter 72A that connects the end plate mounting portion 90 to the telescopic rod of the fluid cylinder 70A that is 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 ends of the guide rods 70B are connected by a connecting member 70C so that the guide rods 70B are always kept parallel to each other.

Also, the end plate mounting section 90 is connected to the horizontal movement section 50 through the horizontal base 73 together with the height direction movement section 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. The horizontal moving portion 50 has a driving side horizontal moving portion 50A and a driven side horizontal moving portion 50B which are both arranged parallel to each other in the horizontal direction. A motor 50C is provided. The horizontal base 73 spans between the drive side horizontal movement section 50A and the driven side horizontal movement section 50B. The operation control unit 80 controls the operations of the horizontal moving unit 50 and the height moving unit 70, respectively, so that the end plate placement unit 90 can be moved in the height direction and the horizontal direction.

Next, each configuration of the end plate mounting portion 90 will be described. The end plate mounting body 10 in this embodiment includes a bottom plate 12 on which the end plate T having a plurality of refrigerant pipe insertion holes TH formed at predetermined intervals along the longitudinal direction, and and upright walls 14 respectively upright from the edges of the . In addition, the dimension in the lateral direction of the bottom plate 12 (the axial direction of the guide pins 21) in the present embodiment (the inner width dimension of the end plate mounting body 10) is the lateral direction of the end plate T (the axial direction of the guide pins 21). ) is used. By adopting such a form of the end plate mounting body 10 , a gap is formed between the end plate T mounted on the end plate mounting body 10 and the upright wall 14 . This gap provides an appropriate backlash when inserting the guide pin 21 into the end plate T, which will be described later, and allows the guide pin 21 to be inserted into the end plate T while absorbing the dimensional difference between the two. As a result, the guide pins 21 are more likely to be attached to the end plate T than when the mounting position of the end plate T on the end plate mounting body 10 and the mounting posture of the end plate T on the end plate mounting body 10 are excessively corrected. This is advantageous in that the success rate of insertion can be improved.

The standing wall 14 in the present embodiment is provided so that the guide pin 21 held by the guide pin holder 20 at the position of the refrigerant pipe insertion hole TH formed in the end plate T can reciprocate in the horizontal direction. It has an avoidance unit 14A. In this embodiment, the notch portion formed in the portion where the guide pin 21 reciprocates is used as the guide pin avoiding portion 14A, but it is not limited to this form. If the height dimension of the standing wall 14 is formed to be lower than the height of the refrigerant pipe insertion hole TH of the end plate T, the standing wall 14 without the guide pin avoiding portion 14A can be employed.

In addition, the bottom plate 12 has one through hole 12A passing through the bottom plate 12 in the plate thickness direction, or a plurality of through holes 12A in the longitudinal direction of the bottom plate 12 (the direction orthogonal to the axis of the guide pin in the horizontal plane). An end plate support 16 formed to be smaller than the inner diameter of the through hole 12A, inserted into the through hole 12A, and capable of protruding 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 extending and contracting the end plate support fluid cylinder 18 attached to the end plate mounting member 10 . The expansion and contraction of the end plate support fluid cylinder 18 is controlled by a motion control unit 80 based on a motion 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 holder 20 in this embodiment can be brought into contact with each other by the horizontal contact/separation means 40 . Here, a fluid cylinder is used as the horizontal contact/separation means 40 . The extensible portion of the fluid cylinder, which is the horizontal contact/separation means 40, is connected to the end plate mounting body 10, the guide pin holder 20 is made independent of the fluid cylinder, and the operation control unit 80 drives the fluid cylinder. As a result, the end plate mounting body 10 and the guide pin holder 20 can be brought into contact with and separated from each other. The motion control unit 80 controls the expansion and contraction motion of the fluid cylinder, which is the horizontal contact/separation means 40, based on a motion control program pre-stored in a storage unit (not shown).

Furthermore, the end plate mounting body 10 is attached with the height direction moving means 60, and the end plate mounting body 10 moves in the height direction of the end plate mounting part 90 as a whole. is capable of independent vertical movement. Also, the guide pin holder 20 is directly attached to the end plate mounting portion 90 . That is, by enabling the height of the end plate mounting body 10 to be changed by the height direction moving means 60, the relative height position between the end plate mounting body 10 and the guide pin holder 20 can be changed. of. A fluid cylinder can be exemplified as such a height direction moving means 60 . The operation of the height direction moving means 60 (the expansion and contraction operation of the fluid cylinder) is controlled by the operation control program and the operation control section 80 .

The refrigerant pipe holding portion 30 is formed in the end plate T to hold the refrigerant pipe 31 in a horizontal state so that the refrigerant pipe 31 for circulating the refrigerant is inserted into the refrigerant pipe insertion hole TH of the end plate T. The refrigerant pipe 31 is held in a state in which the flow passage cross section of the refrigerant pipe 31 faces the refrigerant pipe insertion hole TH. As shown in FIG. 2, the refrigerant pipe holder 30 in this embodiment has two holders 32 that hold the refrigerant pipe 31 at two positions in the longitudinal direction. These two holders 32 are provided so as to be horizontally movable independently of the end plate mounting section 90 by a horizontal movement mechanism (not shown). Refrigerant pipes 31 are appropriately supplied to the refrigerant pipe holding unit 30 in this embodiment 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 move toward and away from the guide pin holder 20 . Alternatively, the refrigerant pipe holding portion 30 may be fixed, and the guide pin holder 20 may be brought into contact with or separated from the refrigerant pipe holding portion 30 by driving the horizontal contact/separation means 40 or the horizontal moving portion 50. .

Next, a method of setting an end plate to a heat exchanger using the heat exchanger end plate setting device 100 according to the present embodiment will be described with reference to FIGS. 4 to 12. FIG. FIG. 6 is a schematic process diagram of a method for setting an end plate to a heat exchanger using the heat exchanger end plate setting device according to the present embodiment.

An operator starts up an operation control program installed in a storage unit such as a personal computer connected to the heat exchanger end plate setting device 100 (step 1). Next, an operator or an end plate supplying robot (not shown) places the end plate T on the end plate mounting body 10 as shown in FIG. 4 (step 2). The end plate T may be placed on the end plate mounting body 10 in the state shown in FIG. 18 can be performed to cause the end plate support 16 to protrude from the top surface of the bottom plate 12 to bring the end plate T into a stable condition. It goes without saying that the position of the end plate support 16 does not interfere with the position of the guide pin 21 . As a method for detecting the mounting state of the end plate T on the end plate mounting body 10, an image recognition device or a contact sensor or the like ( (not shown), the operation control unit 80 can make a determination based on the detection signal.

Placement of the end plate T on the bottom plate 12 of the end plate mounting body 10 is detected by a sensor (not shown) disposed on the end plate mounting body 10, and a detection signal is transmitted to the operation control section 80. The motion control unit 80 executes processing (step 3) for operating (shortening) the horizontal contact/separation movement means 40 . As a result, the end plate mounting member 10 approaches the guide pin holder 20, and as shown in FIG. It is inserted into the insertion hole TH (step 4).

Next, the operation control section 80 operates the drive motor 50C of the horizontal moving section 50 as shown in FIG. The pipe holding portion 30 is approached, and the tip of the guide pin 21 through which the end plate T is inserted is inserted into the tip (open end face) of the refrigerant pipe 31 held by the refrigerant pipe holding portion 30 (step 5). Execute. As a result, the axis of the guide pin 21 and the axis of the refrigerant pipe 31 are arranged on the same axis. Subsequently, as shown in FIG. 9, the operation control unit 80 drives (extends) the horizontal movement means 40 to bring the end plate mounting body 10 closer to the refrigerant pipe holding unit 30 and insert it into the guide pin 21. A process of inserting the bent end plate T into the refrigerant pipe 31 (step 6) is executed.

Subsequently, as shown in FIG. 10, the operation control unit 80 drives (reduces) the height direction moving means 60 to change the relative height position between the end plate mounting body 10 and the guide pin holder 20, By moving (retracting) the end plate mounting body 10 to a position lower than the guide pin holder 20, the end plate T inserted into the refrigerant pipe 31 is separated from the end plate mounting body 10 (step 7). Execute. Subsequently, as shown in FIG. 11, the operation control section 80 operates the drive motor 50C of the horizontal moving section 50 to move the end plate mounting section 90 to the refrigerant pipe holding section 30 as indicated by the arrow B in the drawing. (step 8) is executed. As a result, the end plate T becomes independent from the end plate mounting portion 90 and transferred to the refrigerant pipe 31 .

Next, as shown in FIG. 12, the operation control unit 80 operates (shortens) the height direction moving unit 70 so that the end plate mounting unit 90 and the refrigerant pipe holding unit 30 move toward each other as indicated by arrow C in the figure. , and the end plate mounting portion 90 is retracted below the refrigerant pipe holding portion 30 (step 9). Refrigerant pipes 31 with end plates T mounted thereon in this manner move horizontally away from end plate mounting portion 90 together with refrigerant pipe holding portion 30 by the operation control portion 80 operating a horizontal movement mechanism (not shown). (step 10). After executing step 10, the operation control unit 80 executes processing for confirming whether or not there is an end plate T or refrigerant pipe 31 to be processed (step 11). After returning to the state where the end plate T can be placed on the end plate mounting body 10 in step 2, the processing up to step 10 is repeatedly executed. When either the prepared end plate T or the refrigerant pipe 31 is finished (No route in step 11), the operator or the operation control unit 80 suspends the operation control program, and attaches the end plate T to the refrigerant pipe 31. End the processing (END).

In the above process flow, the procedure for attaching the end plate T to the state before the refrigerant pipe 31 is inserted into the stacked heat radiation fins (not shown) is shown. After laminating the heat radiation fins on the refrigerant pipe 31 or after inserting the refrigerant pipe 31 into the laminated heat radiation fins, the end plate T can be mounted in the same manner as the above procedure. , the detailed description is omitted here. By attaching the end plate T to the refrigerant pipe 31 (heat exchanger) inserted through the heat radiation fins laminated as described above, the heat exchanger is attached to the object (for example, the housing of the outdoor unit of an air conditioner). can be attached to

The heat exchanger end plate setting device 100 according to the present invention and the method for mounting the end plates T to the refrigerant pipes 31 using the same have been described above based on the embodiments, but the heat exchanger end plate setting device according to the present invention 100 and the method of attaching the end plate T to the refrigerant pipe 31 using this are not limited to the embodiments described above. For example, in the heat exchanger end plate setting device 100 of the embodiment described above, the horizontal contact/separation means 40, the height direction movement means 60, and the height direction movement portion 70 are all fluid cylinders. Although not limited to fluid cylinders, other known configurations can be employed.

Moreover, although the horizontal direction movement part 50 in this embodiment demonstrated the form which moves the end plate mounting part 90 in a horizontal direction, it is not limited to this form. Even if the horizontal moving part 50 moves the refrigerant pipe holding part 30 in the horizontal direction, the same operation as in the present embodiment is possible. In this case, the configuration of the horizontal movement mechanism for horizontally moving the refrigerant pipe holding portion 30 as in the present embodiment can be omitted. The horizontal moving part 50 only needs to be able to move at least one of the end plate mounting part 90 and the refrigerant pipe holding part 30 in the horizontal direction.

In the above embodiment, in step 10, the operation control unit 80 operates the horizontal movement mechanism (not shown) to move the refrigerant pipe 31 along with the refrigerant pipe holding unit 30 horizontally away from the end plate mounting unit 90. The horizontal direction may be the axial direction of the refrigerant pipes 31 (horizontal direction in FIG. 12) or the arrangement direction of the refrigerant pipes 31 (the depth direction with respect to the paper surface of FIG. 12). can be

Moreover, it is also possible to employ a configuration in which various modifications of the embodiments described above are appropriately combined.
