[0006] -Technical Problem to be Solved by the Invention-

[0007] After the fins are manufactured at the manufacturing site, they are transported to the integration site. Then, when a plurality of fins are longitudinally stacked to a certain height at the integration site, a transportation process of transporting the stacked plurality of fins to the next processing site is performed. However, if the plurality of fins are longitudinally stacked as described above, it is difficult to stably integrate the fins. Since the plurality of fins cannot be stacked very high, the time interval from performing the transportation process to performing the next transportation process becomes short, and the frequency of the transportation process increases. Since the manufacturing process of the fins at the manufacturing site is interrupted each time the handling process is performed, if the frequency of the transportation increases due to the inability to stably integrate the fins, it is difficult to make the fin manufacturing equipment operate continuously and stably.

[0008] An object of the present disclosure is to be able to stably integrate fins.

[0035] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. It should be noted that the present disclosure is not limited to the embodiments shown below, and various modifications can be made without departing from the technical idea of the present disclosure. Each drawing is used to schematically illustrate the present disclosure, and for easy understanding, the dimensions, ratios, or quantities may be exaggerated or simplified as needed.

[0036] Hereinafter, exemplary embodiments will be described in detail with reference to the drawings.

[0037] <Structure of the Fin>

[0038] Figure 1 is a top view of the fin 1 for a heat exchanger. In Figure 1Among them, the X-axis direction and the Y-axis direction are perpendicular to each other. The heat exchanger is provided, for example, in the indoor unit or the outdoor unit of an air conditioner. The heat exchanger is a device that condenses or evaporates the refrigerant using air as a cooling source or a heating source, and is, for example, a component of the refrigerant circuit of a vapor compression refrigeration device. As the refrigerant circulating in the refrigerant circuit, for example, carbon dioxide refrigerant is used.

[0039] The fin 1 includes a plurality of structural units 10. The plurality of structural units 10 are arranged continuously in the X-axis direction. The structural unit 10 includes a plate-like portion 11, a continuous portion 12, a fin groove portion 13, a lattice portion 14, and fin wings 15.

[0040] The plate-like portion 11 is a plate-like member. The plurality of plate-like portions 11 are arranged along the X-axis direction. The continuous portion 12 is provided between adjacent plate-like portions 11.

[0041] The continuous portion 12 is a plate-like member. The continuous portion 12 is provided to be continuous with each adjacent plate-like portion 11. On the surfaces in the X-axis direction and the Y-axis direction, the continuous portion 12 is coplanar with each adjacent plate-like portion 11. The continuous portion 12 is located between adjacent plate-like portions 11. The continuous portion 12 is located on the other side in the Y-axis direction of the fin 1.

[0042] The fin groove portion 13 is a space provided between adjacent plate-like portions 11 and the continuous portion 12. The fin groove portion 13 extends in the Y-axis direction. Between adjacent plate-like portions 11, the fin groove portion 13 is provided on one side in the Y-axis direction with respect to the continuous portion 12. In the fin groove portion 13, one side and the other side in the X-axis direction are respectively closed due to the presence of the plate-like portion 11, one side in the Y-axis direction is open, and the other side in the Y-axis direction is closed due to the presence of the continuous portion 12. The fin groove portion 13 includes a first groove portion 131 and a second groove portion 132. The first groove portion 131 is a portion of the fin groove portion 13 located on one side in the Y-axis direction. The second groove portion 132 is a portion of the fin groove portion 13 located on the other side in the Y-axis direction. The second groove portion 132 is continuous with the first groove portion 131, and the second groove portion 132 is formed so as to protrude from the first groove portion 131 toward the other side in the Y-axis direction. The fin groove portion 13 includes an opening 133 communicating with the external space. The opening 133 is formed on one side in the Y-axis direction of the first groove portion 131.

[0043] A flat tube for transporting the refrigerant is inserted into the fin groove portion 13. In order to be able to embed the flat tube, in the X-axis direction, the size of the second groove portion 132 is set corresponding to the size of the flat tube. In the X-axis direction, by configuring the size of the first groove portion 131 to be larger than the size of the second groove portion 132, when the flat tube is inserted into the fin groove portion 13, the first groove portion 131 functions as a guide groove. As a result, the flat tube can be easily inserted into the fin groove portion 13.

[0044] The lattice part 14 is provided on the plate-like part 11 and is located at the center of the plate-like part 11 in the Y-axis direction. The lattice part 14 is composed of raised parts and non-raised parts. The raised parts are the parts that are raised in the thickness direction of the fin 1. The non-raised parts are the flat parts that are not raised in the thickness direction of the fin 1.

[0045] The fin wings 15 are provided to limit the intervals between adjacent fins 1 in the thickness direction and are arranged on both sides of the lattice part 14 in the Y-axis direction.

[0046] It should be noted that the fin 1 only needs to have at least a plurality of fin groove parts 13, and there are no particular limitations on other structures of the fin 1.

[0047] <First Embodiment>

[0048] The first embodiment of the integration method of the fin 1 will be described.

[0049] <Manufacture and Conveyance of Fin>

[0050] The fin 1 is manufactured at the manufacturing site P by stamping a metal plate with a mold or the like. In the first embodiment, the fin 1 just manufactured at the manufacturing site P is arranged in the state of the horizontal posture F.

[0051] The state of the horizontal posture F means the state in which the fin 1 lies down with the opening 133 of the fin groove part 13 (refer to Figure 1 ) facing horizontally.

[0052] <First Modification Example of Fin Posture>

[0053] At the posture change site QA, the posture of the fin 1 is changed.

[0054] In the first embodiment, at the posture change site QA, the posture of the fin groove part 13 is changed from the horizontal posture F to the downward posture G. The downward posture G means the posture of the fin 1 when the opening 133 of the fin groove part 13 faces downward in the vertical direction.

[0055] A plurality of placing tables Q11 are arranged at the posture change site QA. The plurality of placing tables Q11 are arranged in a row. There is a gap Q12 between adjacent placing tables Q11.

[0056] A second guide plate Q14 is provided on each of the plurality of placing tables Q11.

[0057] The plurality of fins 1 manufactured at the manufacturing site P are conveyed along the conveying direction E while being separated by a plurality of first guide plates Q13 and are sent onto the plurality of placing tables Q11. Hereinafter, one fin 1 among the plurality of fins 1 will be described in detail.

[0058] The fin 1 is arranged to be suspended on a plurality of placing tables Q11 in a horizontal posture F. On the plurality of placing tables Q11, by being clamped from both sides by the second guide plate Q14, the state where the fin 1 is arranged on the plurality of placing tables Q11 can be effectively ensured.

[0059] In a state where the fin 1 in the horizontal posture F is placed on the plurality of placing tables Q11, any one of a plurality of fin groove portions 13 (refer to Figure 1 ) exists above the gap Q12 of the placing table Q11 and is opposite to the gap Q12 in the vertical direction.

[0060] A plate-like or linear moving member Q15 is arranged below the gap Q12 of the placing table Q11.

[0061] As Figure 2 and Figure 3 shown, in a state where the fin 1 in the horizontal posture F is placed on the plurality of placing tables Q11, the moving member Q15 rises from below the gap Q12 and passes through the gap Q12. By passing through the gap Q12, the moving member Q15 approaches the fin groove portion 13 of the fin 1 from below and lifts the fin 1. When the fin 1 is lifted by the moving member Q15, the fin 1 rotates about the contact portion between the moving member Q15 and the fin groove portion 13 so that the opening 133 of the fin groove portion 13 faces downward, thereby becoming a state where the moving member Q15 enters the fin groove portion 13, and the posture of the fin 1 changes from the horizontal posture F to the downward posture G. As a result, a state where the moving member Q15 is stuck in the fin groove portion 13 is formed.

[0062] By the moving member Q15 being stuck in the fin groove portion 13, the moving member Q15 comes into contact with the bottom of the fin groove portion 13 of the fin 1 in the downward posture G from below, and the fin 1 is supported by the moving member Q15 from below. Since the moving member Q15 is stuck in the fin groove portion 13, when the moving member Q15 moves, the fin 1 moves together with the moving member Q15 while maintaining the downward posture G.

[0063] <First integration example of fins>

[0064] A tray R1 for integrating the fin 1 is arranged at the integration place RA of the fin 1. The tray R1 is a rectangular frame-shaped member that is open at the top and bottom. A plurality of support members R2 are provided on the tray R1. The plurality of support members R2 are arranged at intervals and in parallel, and extend in the horizontal direction. The support member R2 is a plate-like or linear member that can enter the fin groove portion 13.

[0065] The moving member Q15 moves to the integration place RA of the fin 1 while supporting the fin 1 in the downward posture G. The fin 1 is transferred from the moving member Q15 to the plurality of support members R2.

[0066] When the fin 1 is transferred from the moving member Q15 to the supporting member R2, the supporting member R2 enters the fin groove portion 13, and thus the supporting member R2 is caught in the fin groove portion 13. As a result, while the fin 1 is in the state of maintaining the downward posture G, it is supported by the supporting member R2.

[0067] At the integration site RA, a plurality of fins 1 are integrated in a side-by-side manner in the direction V in which the supporting member R2 extends.

[0068] At the integration site RA, a plurality of fins 1 are integrated in a horizontally stacked manner. The horizontally stacked integration of a plurality of fins 1 refers to the following state: a plurality of fins 1 are arranged side by side in the state of the downward posture G or the upward posture H respectively, and when viewed from the side-by-side direction V of the plurality of fins 1, the fin groove portions 13 of adjacent fins 1 overlap each other.

[0069] <Second Embodiment>

[0070] A second embodiment of the method for integrating the fins 1 will be described.

[0071] <Structure of the Posture Change Site of the Fin>

[0072] As Figure 5 shown in (a), at the posture change site QB of the fin 1, a first guide portion Q21, a first bottom plate portion Q22, a second bottom plate portion Q23, and a third bottom plate portion Q24 are provided.

[0073] As Figure 4 shown in (a) and Figure 5 shown in (a), the first guide portion Q21 is a hollow member having a shape extending along the vertical direction. The first bottom plate portion Q22, the second bottom plate portion Q23, and the third bottom plate portion Q24 are provided inside the first guide portion Q21. An opening Q25 that communicates the inside and the outside of the first guide portion Q21 is formed at the lower part of the first guide portion Q21.

[0074] The first bottom plate portion Q22 is rotatably supported. The first bottom plate portion Q22 is a plate-like member. The first bottom plate portion Q22 includes a first placement surface Q221 for placing the fin 1 manufactured at the manufacturing site P (refer to Figure 2 ). The first bottom plate portion Q22 includes a central portion Q222 as the rotation center and a rotation end portion Q223 that rotates around the central portion Q222.

[0075] By rotating the first bottom plate portion Q22, the posture of the first bottom plate portion Q22 is changed to either a horizontal posture S1 or an inclined posture S2. The horizontal posture S1 is a posture in which the first placement surface Q221 of the first bottom plate portion Q22 is in a state parallel to the horizontal direction J. The inclined posture S2 is a posture in which the first placement surface Q221 of the first bottom plate portion Q22 is inclined downward toward one direction side J1 with respect to the horizontal direction J.

[0076] As Figure 5 (a) shows, the second bottom plate portion Q23 is provided below the first bottom plate portion Q22. The second placement surface Q231 of the second bottom plate portion Q23 is a plate-like member inclined downward toward one direction side J1 with respect to the horizontal direction J.

[0077] As Figure 4 (b) and Figure 5 (a) shows, the third bottom plate portion Q24 is provided below the second bottom plate portion Q23. The third bottom plate portion Q24 is a plate-like member. The third bottom plate portion Q24 is supported in a rotatable manner. By rotating the third bottom plate portion Q24, the posture of the third bottom plate portion Q24 is changed to either an inclined posture T1 or a vertical posture T2. The inclined posture T1 is a posture in which the third placement surface Q241 of the third bottom plate portion Q24 is inclined downward toward one direction side J1 with respect to the horizontal direction J. The vertical posture T2 is a posture in which the third placement surface Q241 of the third bottom plate portion Q24 is parallel to the vertical direction.

[0078] As Figure 5 (a) shows, a support member R2 is arranged at the integration place RB of the fins 1. The support member R2 is provided below the opening Q25 of the first guide portion Q21.

[0079] <Second modification example of fin posture>

[0080] As Figure 4 (a) and Figure 5 (a) shows, the fins 1 manufactured at the manufacturing place P (refer to Figure 2 ) are placed on the first placement surface Q221 of the first bottom plate portion Q22 in the horizontal posture S1 in the posture change place QB in the lateral posture F.

[0081] Hereinafter, the state in which the fins 1 are placed on the first placement surface Q221 of the first bottom plate portion Q22 in the horizontal posture S1 in the lateral posture F may sometimes be described as a horizontal placement state.

[0082] When the fins 1 are in the horizontal placement state, the continuous portion 12 of the fins 1 is located on the center portion Q222 side of the first bottom plate portion Q22, and the opening 133 of the fin groove portion 13 is located on the rotation end portion Q223 side of the first bottom plate portion Q22.

[0083] The fin 1 manufactured at the manufacturing site P is placed on the first placement surface Q221 of the first bottom plate portion Q22. When the fin 1 is in a horizontally placed state, the posture of the first bottom plate portion Q22 is changed to an inclined posture S2. When the posture of the first bottom plate portion Q22 is changed to the inclined posture S2, the fin 1 slides off the first placement surface Q221. When the fin 1 slides off the first placement surface Q221, it slides off from the opening 133 side of the fin groove portion 13.

[0084] After the fin 1 slides off the first placement surface Q221, it falls from the first bottom plate portion Q22 and reaches the second bottom plate portion Q23, and slides off the second placement surface Q231 of the second bottom plate portion Q23.

[0085] As Figure 4 (b) and Figure 5 (a) shows that after the fin 1 slides off the second placement surface Q231, it falls from the second bottom plate portion Q23 and reaches the third bottom plate portion Q24, and is placed on the third placement surface Q241 of the third bottom plate portion Q24.

[0086] When the fin 1 is placed on the third placement surface Q241 of the third bottom plate portion Q24, the posture of the third bottom plate portion Q24 is changed from the inclined posture T1 to the vertical posture T2. Thereby, the fin 1 falls from the third bottom plate portion Q24 in a downward posture G state with the opening 133 of the fin groove portion 13 facing downward.

[0087] As Figure 4 (c), Figure 5 (a) and Figure 5 (b) show that the fin 1 falling from the third bottom plate portion Q24 reaches the integration site RB. At this time, the fin 1 falls in the downward posture G state, whereby the support member R2 enters the fin groove portion 13 through the opening 133, and thus the support member R2 is stuck in the fin groove portion 13.

[0088] As in the above second modification example, at the posture change site QB, the posture of the plurality of fins 1 is changed, whereby at the integration site RB, as in the first integration example (refer to Figure 3 )), the plurality of fins 1 are horizontally stacked and integrated in the downward posture G state.

[0089] <Third Embodiment>

[0090] A third embodiment of the method for integrating the fins 1 will be described.

[0091] <Structure of the Posture Change Site of the Fin>

[0092] As Figure 6As shown, an inclined surface Q3 that is inclined downward with respect to the horizontal direction is provided at the posture change location QC of the fin 1. A plurality of support members R2 are provided at the lower portion of the inclined surface Q3.

[0093] <Third Modification of Fin Posture>

[0094] The fins 1 manufactured at the manufacturing location P (refer to Figure 2 ) are arranged in a lateral posture F with the opening 133 of the fin groove portion 13 facing the inclined surface Q3 side at the upper portion of the inclined surface Q3. The fin 1 is pushed out toward the inclined surface Q3 side by an arm member (not shown) or the like from the state of being located at the upper portion of the inclined surface Q3 and slides down along the inclined surface Q3. When the fin 1 slides down along the inclined surface Q3, the fin 1 inclines along the inclined surface Q3, whereby the posture of the fin 1 is changed so that the opening 133 of the fin groove portion 13 faces the lower side. When the fin 1 slides down along the inclined surface Q3, the fin 1 slides down from the opening 133 side of the fin groove portion 13. When the fin 1 reaches the lower portion of the inclined surface Q3, the fin 1 moves from the opening 133 side to the plurality of support members R2. As a result, any one of the plurality of support members R2 enters the fin groove portion 13 through the opening 133 and is stuck in the fin groove portion 13, whereby the fin 1 is supported by the support member R2 in a state of being in a downward-facing posture G.

[0095] As in the third modification example, at the posture change location QC, the plurality of fins 1 are processed to change the posture of the fins 1 by dropping the fins 1 using the inclined surface Q3. Thus, at the integration location RC, as in the first integration example (refer to Figure 3 ), the plurality of fins 1 are integrally stacked laterally in a state of being in a downward-facing posture G.

[0096] <Fourth Embodiment>

[0097] A fourth embodiment of the method for integrating the fins 1 will be described.

[0098] A fourth embodiment of the method for integrating the fins 1 will be described.

[0099] <Structure of Fin Posture Change Location and Integration Location>

[0100] As Figure 7 shown, a rotating table Q4 is provided at the posture change location QD of the fin 1. An integration table R3 and a plurality of support members R2 are provided at the integration location RD of the fin 1.

[0101] The rotating table Q4 is supported in such a manner that it can rotate with the fin 1 placed thereon. The integration table R3 is a plate-like member on which the integrated fins 1 are placed. The rotating table Q4 is arranged around the integration table R3. A plurality of support members R2 are arranged on the upper portion of the integration table R3. The plurality of support members R2 are arranged side by side at intervals.

[0102] <Fourth Modification Example of Fin Posture>

[0103] The fin 1 manufactured at the manufacturing site P (refer to Figure 1 ) is placed on the rotating table Q4 in the state of the horizontal posture F. The rotating table Q4 rotates in the state where the fin 1 in the horizontal posture F is placed. The fin 1 rotates together with the rotating table Q4. By the rotation of the rotating table Q4, the fin 1 is erected, and the posture of the fin 1 is changed from the horizontal posture F to the upward posture H.

[0104] The upward posture H indicates the posture of the fin 1 when the opening 133 of the fin groove portion 13 faces upward in the vertical direction.

[0105] The fin 1 in the upward posture H is pushed out from the rotating table Q4 toward the integration site RD side by an arm member (not shown) or the like. As a result, any of the plurality of support members R2 enters the fin groove portion 13 and gets stuck in the fin groove portion 13, and the fin 1 is arranged on the integration table R3 in the state of the upward posture H.

[0106] <Second Integration Example of Fins>

[0107] As in the above fourth modification example, at the posture change site QD, the process of changing the posture of the fin 1 by erecting the fin 1 using the rotating table Q4 is performed on the plurality of fins 1. As a result, at the integration site RD, the plurality of fins 1 are horizontally stacked and integrated in the state of the upward posture H.

[0108] <Effect>

[0109] As described above, at the integration site RA of the fin 1, the fin 1 is arranged in a state where the opening 133 of the fin groove portion 13 faces upward or downward. Thus, a plurality of fins 1 can be horizontally stacked and integrated. Thus, compared with the case of vertically stacking a plurality of fins 1, the fins 1 can be stably integrated, more fins 1 can be integrated, and the fins 1 can be stably integrated. As a result, the frequency of the conveying process can be reduced, and the manufacturing equipment of the fin 1 can work stably.

[0110] The embodiments and modification examples have been described above, but it should be understood that various changes can be made to their forms and specific situations without departing from the gist and scope of the claims (for example, the following (1)). As long as the functions of the objects of the present disclosure are not affected, the embodiments, modification examples, and other embodiments can be appropriately combined or replaced.

[0111] (1)In the first to fourth embodiments, it may also be configured such that the posture change locations QA, QB, QC, and QD of the fin 1 are set at locations away from the manufacturing location P of the fin 1, and a conveying process is performed using a conveying member such as a conveyor to move the fin 1 manufactured at the manufacturing location P away from the manufacturing location P and convey it to the posture change locations QA, QB, QC, and QD. Thereby, it is possible to suppress the fin 1 from staying at the manufacturing location P of the fin 1, and the fin 1 can be manufactured smoothly.
