An apparatus for manufacturing a fin integrated body of a fin for a heat exchanger according to the present embodiment will be described in detail based on the embodiment.

(First embodiment)

The whole structure of the fin integrated body manufacturing apparatus of the fin for heat exchangers which concerns on this embodiment is shown in FIG.1 and FIG.2. The fin integrated body manufacturing apparatus 100 of the fins for heat exchangers in this embodiment (henceforth only the fin integrated body manufacturing apparatus 100) is a heat exchanger fin from the thin plate 12 supplied from the material supply part 10. The press device 20 forming 14, the table circulation device 30 conveying the fin assembly 15 formed by integrating the fins 14 for heat exchangers, and the fin assembly 15 are pulled out A pin integrated body taking-out device (40) and a central operation control unit (50) that collectively control these operations are provided.

The material supply unit 10 is an uncoiler 10A in which a thin plate 12 made of unprocessed metal such as aluminum is wound in a coil shape, and a feeder 10B that unwinds the thin plate 12 from the uncoiler 10A at a predetermined timing. have Since the material supply part 10 in this embodiment just needs to employ|adopt a well-known structure, detailed description here is abbreviate|omitted.

The press device 20 has a mold device 22 disposed therein, press-works the thin plate 12 supplied from the material supply unit 10, and has a cutout or a through hole through which the heat exchange tube is inserted. The fins 14 for heat exchangers are formed through the upper body 13 . The mold apparatus 22 has an upper die set 22A and a lower die set 22B, and one of the upper die set 22A or the lower die set 22B is provided so that one of the upper die set 22A or the lower die set 22B can approach and detach from the other. The metal strip|belt-shaped body 13 sent from the metal mold|die apparatus 22 is individualized by a hot slit device and a cut-off device (not shown) in each of the width direction and a sending direction, and is formed into the fins 14 for heat exchangers. . The heat exchanger fins 14 formed in this way are adsorbed and held by the suction unit 24 provided at the most downstream position of the mold device 22 , and the table circulation device 30 provided at a position adjacent to the downstream side of the press device 20 . is sent to

The table circulation apparatus 30 in this embodiment attaches the table 36 along the rotation direction to the upper surface of the table holding board 34 which can be rotated by the motor 32 which is a rotation drive apparatus. The driving control of the motor 32 is executed by the central operation control unit 50 .

The table holding plate 34 is formed in the shape of a disk having a rotating shaft in the center. Tables 36 are attached to the table holding plate 34 at equal intervals (at intervals of 90 degrees centering on the rotation axis in a horizontal plane) at four places along the outer periphery of the table holding plate 34 . Since table attachment holes (not shown) are drilled at predetermined intervals along the outer peripheral edge in the upper surface of the table holding board 34 of this embodiment, the table 36 is located at any position of the table holding board 34 . ) can be attached. The rotating shaft of the table holding plate 34 is directly connected to the output shaft of the motor 32 through a speed reducer or directly.

When the motor 32 is rotationally driven according to the instruction of the central operation control unit 50, the table holding plate 34 rotates about the rotation axis, and each table 36 moves between the stack position SP and the buffer position BP. It will cyclically move within the position (position) of four places of the take-out position RP and the standby position WP.

Stacking position SP (stacking position) is a position directly below the adsorption|suction part 24 of the press apparatus 20, The stack fin which installed the fin 14 for heat exchangers from the press apparatus 20 upright on the table 36. It is a position where the fin assembly 15 of the fins 14 for heat exchangers is obtained by integrating|accumulating on the stacker 31 (table 36) until it becomes a predetermined height dimension along (37). The buffer position BP (buffer position) sends the fin aggregate 15 of the fins 14 for the heat exchanger accumulated in the stacker 31 to a predetermined integration height from the stack position SP from the stack position SP, and waits. position to do it.

The take-out position RP (take-out position) is a position immediately after the buffer position BP, in which the pin aggregate 15 having a predetermined integration height at the stack position SP is sent together with the stack pin 37, so that the pin aggregate It is the position where (15) is taken out. The standby position WP (standby position) is a position following the take-out position RP, and in a position immediately before the stacking position SP, the stack pin 37 stands by again at a predetermined position of the table 36 and is installed. is the position to

3 and 4, on the upper surface of the table 36 of the stacker 31 in the present embodiment, the first spacers 33A and the stack pin holders 38 are arranged in a scattering arrangement, respectively. On the upper surface of the first spacer 33A, there is attached a pin support body 35 having both ends projecting outward of the table 36 in an arrangement to cross the planar area of the table 36 . On the upper surface of the stack pin holder 38, the second spacer 33B and the stack pin guide plate 39 in which the stack pin 37 is inserted into a cavity (through hole) are placed in the order of the substrate, respectively. As shown in Fig. 3, the first spacers 33A are provided in an arrangement with the second spacers 33B sandwiched therebetween at positions lateral to the second spacers 33B.

In addition, a plurality of stack pins 37 can be inserted and removed from the stack pin holder 38 . The central operation control unit determines whether or not the stack pin 37 is placed in or out of the stack pin holder 38, the operation control program of the pin integrated body taking-out device 40 described later executes a series of operations without generating an error. If (50) (corresponding to the stack pin standing confirmation means) confirms, it is possible. Here, the series of operations means taking out the pin aggregate 15 together with the stack pin 37 from the stack pin holder 38, then separating the pin aggregate 15 and the stack pin 37, and the stack pin ( 37) refers to processing until only the stack pin holder 38 is returned.

As another specific example of the stack pin standing confirmation means, a stack pin sensor may be arranged in the stack pin holder 38 . In this case, the confirmation information of the standing state of the stack pin 37 in the stack pin holder 38 by the stack pin sensor may be continuously transmitted to the central operation control unit 50 .

The heat exchanger fins 14 are sequentially placed on the stack fins 37 from the adsorption unit 24 of the press device 20 , and the heat exchanger fins 14 are sequentially integrated along the stack fins 37 to form a fin assembly. (15) is formed. The pin assembly 15 is supported by the first spacer 33A and the pin support body 35 in a state where the bottom surface thereof has a gap S between it and the upper surface of the table 36 .

In addition, at the stacking position SP of this embodiment, the lifting device 60 which moves the pin support body 35 in the height direction of the stack pin 37 is arrange|positioned (refer FIGS. 1 and 2). The lifting device 60 is positioned below the moving surface of the stacker 31 at a position outside the planar region of the stacker 31 (table 36), which is a lateral position of the stacker 31 (in this embodiment, a table holding plate ( 34) and installed in the lower position). Although the lifting device 60 in this embodiment is a form which raises and lowers the pin support body 35 in the state hold|maintained by the plate-shaped body, it can also be set as the structure which grabs the both ends of the pin support body 35 by the holding part which can raise/lower. This is advantageous in that it becomes possible to slide the pin support body 35 and the pin aggregate 15 along the stack pins 37 in a stable state.

The raising/lowering device 60 in this embodiment makes 1 cycle from the time of conveyance of the stacker 31 to the stacking position SP to the time of conveyance of the stacker 31 to the buffer position BP, and the central operation control part 50 ), the lifting operation is controlled. In addition, in any one of the lifting device 60 or the pin aggregate taking-out apparatus 40 to be described later, the height of the pin aggregate 15 integrated in the pin support 35 has reached a preset height. An optical sensor (not shown) is installed. As the optical sensor, a known configuration with a measurement light irradiator and a light receiving sensor can be adopted. When the optical sensor according to the present embodiment detects that the measurement light irradiated from the measurement light irradiation unit is blocked by the pin integrated body 15 when the integration height of the pin integrated body 15 reaches a predetermined height, the center The form of transmitting the integration height arrival detection signal to the operation|movement control part 50 was employ|adopted.

At the start of the integration process when the fins 14 for heat exchangers 14 are integrated into the stacker 31 along the stack fins 37 at the stack position SP, the central operation control unit 50 controls the fin supports 35 and the stack. The operation of the lifting device 60 is controlled to raise the pin guide plate 39 along the stack pins 37 . The pin support 35 and the stack pin guide plate 39 are positioned near the upper end of the stack pin 37 , and are raised to an integration start position near the upper end of the stack pin 37 .

As described above, the position of the fin support 35 at the time of starting the stacking of the heat exchanger fin 14 along the stack fin 37 at the stack position SP approaches the adsorption unit 24 of the press device 20 . By doing so, the fall of the fin 14 for heat exchangers discharged|emitted from the adsorption|suction part 24 can be made small. Therefore, the deformation|transformation of the fin 14 for heat exchangers at the time of the fin 14 for heat exchangers discharged|emitted from the adsorption|suction part 24 landing on the fin support body 35 is prevented. In addition, by guiding the tip (top) of the stack pin 37 at a position as high as possible, the planar position of the tip of the stack pin 37 may be adjusted to the correct position.

The central operation control unit 50 gradually slides the height positions of the fin support body 35 and the stack fin guide plate 39 according to the integration height of the fin assembly 15 of the fin 14 for the heat exchanger on the stack fin 37 . The operation of the lifting device 60 is controlled so that it is moved and brought closer to the table 36 side. In addition, if the central operation control unit 50 determines that the height of the pin integrated body 15 to the stack pin 37 has reached a predetermined integration height by receiving the integration height arrival detection signal transmitted from the optical sensor, the elevating device ( 60) is lowered to the original position, which is a position lower than the moving surface of the stacker 31 . Thereby, the lifting device 60 does not interfere with the table circulation device 30 at the time of operation of the table circulation device 30 .

The central operation control unit 50 determines that the stacking height of the pin aggregates 15 reaches a predetermined stacking height set in advance, and, further, in all the stacked pin holders 38 of the table 36 in the standby position WP. When it is detected that the stack pin 37 is installed upright, a process for driving the motor 32 in the forward direction is executed. By driving the motor 32, the table holding plate 34 rotates in a predetermined direction, and each stacker 31 is sent to the next position (position). Here, the central operation control unit 50 (corresponding to the stack pin stand-by confirmation means) confirms that a series of operations have been executed without the operation control program of the pin integrated body take-out device 40 causing an error, so that the standby position WP ), it is confirmed that the stack pins 37 are erected on all the stack pin holders 38 of the table 36 .

In the present embodiment, with respect to the pin assembly body 15 in the table 36 at the buffer position BP, a guide rod or a refrigerant pipe (not shown) is inserted into the through hole through which the stack pin 37 is not inserted. ) is executed by the central operation control unit 50 . In this way, by inserting a guide rod or a refrigerant pipe through the pin collector 15 in the state where the stack pin 37 is inserted, the table 36 moves from the buffer position BP to the take-out position RP. Collapsing of the pin integrated body 15 during rotation can be prevented.

In the stacker 31 sent from the buffer position BP to the take-out position RP, the pin aggregates 15 along the stack pins 37 are accumulated at a predetermined integration height. The central operation control unit 50 sends the stack pins 37 and the pin aggregate 15 from the table 36 of the stacker 31 in the take-out position to the pin aggregate take-out device 40 disposed at the take-out position RP. ) to take out.

As shown in FIGS. 4 and 5 , the pin integrated body take-out device 40 in the present embodiment includes an upper end clamp 41 that clamps the upper end of the stack pin 37 , and the stack pin 37 . A lower clamping part 42 for clamping the lower end, a vertical movement mechanism 43 for moving the upper clamping part 41 and the lower clamping part 42 up and down, and the upper clamping part 41 and the lower clamping part 42 It has a horizontal movement mechanism 44 for moving in the horizontal direction. Here, the upper end and lower end of the stack pin 37 is a concept including the upper end and the lower end of the stack pin 37 . The operation of the pin integrated body take-out device 40 is controlled by the central operation control unit 50 . Moreover, the pin holding part 46 is attached to the upper side of the lower end clamping part 42. As shown in FIG.

The horizontal movement mechanism 44 is actuated by the instruction from the central operation control part 50, and the pin aggregate take-out device 40 is brought close to the pin aggregate 15 (FIG. 5A). The central operation control unit 50 continuously moves the upper clamping part 41 and the lower clamping part 42 in an open state to the position of the stack pin 37, and closing the upper clamping part 41 to close the stack pin 37) Only the upper end of the is pinched (FIG. 5B). At this time, the bottom surface of the lowermost portion of the pin aggregate 15 is in a state held by the pin support portion 46 .

Next, the central operation control unit 50 operates the vertical movement mechanism 43 to raise only the upper clamping portion 41 and pull out only the stack pin 37 from the stack pin holder 38 (FIG. 5C). Next, the central operation control unit 50 closes the lower clamping portion 42 to clamp the lower end of the stack pin 37 , and operates the horizontal movement mechanism 44 to close the upper and lower portions of the stack pin 37 . The pinched pin aggregate 15 is moved in a direction away from the other pin aggregate 15 (FIG. 5D).

In this way, the pin integrated body take-out device 40 interposes the upper end and the lower end of the stack pin 37 , and the pin integrated body 15 inserted through the stack pin 37 is integrated with the stack pin 37 . It is pulled out from the table 36 (stack pin holder 38) in one state.

The pin aggregate 15 pulled out together with the stack pins 37 from the table 36 is placed sideways on the conveyor 70 as a conveying unit (FIG. 6A). The pin aggregate 15 through which the stack pins 37 are inserted puts the stack pins 37 parallel to the upper surface (ground surface) of the conveyor 70 . Next, the central operation control unit 50 releases the lower clamping portion 42, and moves the lower clamping portion 42 in a direction away from the pin aggregate 15 (upper side in Fig. 6B) (Fig. 6B). ).

Then, as shown in FIG. 6C , the central operation control unit 50 controls the position where the stack pins 37 are not pulled out from the upper end of the pin aggregates 15 (stacks in the through holes of the pin aggregates 15). In a state in which the pin 37 is guided), the lower end of the stack pin 37 is clamped by the lower clamping portion 42 . Then, the stack pin 37 is erected on the stack pin holder 38 of the table 36 from which the stack pin 37 that has already moved to the standby position WP is pulled out.

A stack pin guide plate 39 is arranged at a position directly above the stack pin holder 38 in the present embodiment. A through hole is provided in the stack pin guide plate 39 in the plate thickness direction, and the position of the lower opening of the through hole is aligned with the standing position of the stack pin 37 of the stack pin holder 38, and the upper opening of the stack pin holder 38 is positioned. The opening dimension is formed larger than the lower opening dimension. Thereby, the stack pin 37 can be accurately returned to the original position. In this way, when the stack pin 37 is reinserted into the stack pin holder 38, the stroke amount of an operating part such as an actuator (not shown) attached to the arm of the pin integrated body take-out device 40 is measured by the operating part monitoring means or the center. The operation control unit 50 is monitoring.

In the present embodiment, the operation unit monitoring means or the central operation control unit 50 for monitoring the stroke amount of the operation unit corresponds to the stack pin standing/standing confirmation means. When the operation part monitoring means or the central operation control part 50 does not reach the predetermined stroke amount of the measured stroke amount of the operation part, the series of operations in the pin integrated body take-out device 40 does not end normally (re-entry of the stack pins) It can be concluded that the hypothesis was not carried out accurately).

Then, the central operation control unit 50 confirms that the stack pins 37 are erected on all the stack pin holders 38 of the stacker 31 in the standby position WP, and also the stack position SP. When it is detected that the stacking height of the pin aggregates 15 in , the motor 32 is driven, each stacker 31 in the table circulation device 30 is cyclically moved to the next position, respectively. make it

By repeating the above operation|movement, the process which uses the fin 14 for heat exchangers supplied from the press apparatus 20 as the fin integrated body 15 and sends it sequentially to a next process can be performed fully automatically.

As explained above, according to the fin integrated body manufacturing apparatus 100 of the fins for heat exchangers in this embodiment, by the table circulation device 30, the fin integrated body take-out apparatus 40, and the central operation control part 50, The fins 14 for heat exchangers sent from the press device 20 are removed by circulating the table 36 between the stack position SP, the buffer position BP, the take-out position RP, and the standby position WP. It is possible to automatically perform the process of sequentially sending the integrated body 15 to the next position (process).

According to the structure of the fin aggregate manufacturing apparatus 100 of the fin for heat exchangers in this embodiment, manufacture of the fin 14 for heat exchangers and the fin aggregate 15 which integrated this were formed, and the formed fin aggregate ( 15) can be automated to send to the next process. Thereby, there is no occurrence of problems, such as a handling error of the fin assembly 15 due to human intervention, and it becomes possible to manufacture the fin assembly 15 of the fin 14 for a heat exchanger extremely efficiently.

The pin pressing mechanism 80 is for pressing the pin aggregate 15 integrated on the upper surface of the table 36, and the position of both ends of the pin aggregate 15 (length when the pin aggregate 15 is viewed in a plan view) It is provided so that the pin aggregate 15 may be pressed from both ends in the direction). The pin press mechanism 80 in this embodiment is a pin press body 82 and a pin press body 82 which abut against the positions of both ends of the pin aggregate body 15 and press the pin aggregate body 15 . It has the rotation motor 84 as a switching control part which switches and controls the pushing state of (15) and a non-pressing state. The operation of the rotation motor 84 is controlled by the central operation control unit 50 . When the rotation motor 84 rotates between the state which made the pin press body 82 stand up with respect to the upper surface of the table 36, and the state which becomes horizontal with the upper surface of the table 36, the holding state of the pin assembly body 15 and the non-oil state are transition-controlled.

The operation of the pin pressing mechanism 80 will be described. 9 to 11 are plan views of essential parts for explaining the operation of the pin pressing mechanism 80 at each position (position). Here, the operation in each position (position) with respect to the pin pressing mechanism 80 arranged on the table 36 at the stack position SP in Fig. 9 will be described.

In the stacking position SP, as shown in FIG. 9 , in the pin press mechanism 80 , the pin press body 82 is in a state in which the pin press body 82 stands upright with respect to the upper surface of the table 36 . Thus, by making the pin press body 82 upright on the upper surface of the table 36, when integrating the pin aggregate body 15, the pin press body 82 does not interfere.

When the height of the pin aggregate 15 integrated on the upper surface of the table 36 in the stacking position SP reaches a preset height, the central operation control unit 50 controls the table 36 in the SP of FIG. As shown, the rotation motor 84 is actuated, and the pin press body 82 is rotated so that it may become parallel to the upper surface of the table 36 (it may become horizontal). In this way, the pin aggregate 15 is sandwiched from both ends of the pin aggregate 15 and the pin aggregate 15 is pressed with the pin presser 82, so that when the table 36 is rotated, the pin It is possible to prevent the integrated body 15 from collapsing.

While the table 36 is rotating and waiting at the buffer position BP, as shown by the table 36 in FIG. The state in which the clamped is maintained. In addition, at the buffer position BP, the quality check of the fin assembly 15, the extraction process of the stack fin 37, and the insertion process of a guide rod or a refrigerant pipe can also be performed. And also when rotating from the buffer position BP to the take-out position RP, the state which clamped the both end positions of the pin aggregate body 15 with the pin press body 82 is maintained.

And as shown in FIG. 11, in the table 36 in the take-out position RP, the central operation control part 50 is the rotation motor 84 of the pin press mechanism 80 on the side of the pin integrated body take-out device 40 side. ) is actuated to make the pin presser 82 stand up on the upper surface of the table 36 . By doing in this way, it is advantageous that the pin press body 82 is not obstructed when taking out processing of the pin integrated body 15 by the pin integrated body take-out device 40 at the take-out position RP.

And when the take-out process of all the pin aggregates 15 at the take-out position RP is completed, the central operation control part 50 moves the table 36 of the take-out position RP to the standby position WP. In the table 36 moved to the stand-by position WP, all the pin press bodies 82 (on both sides of the pin aggregate body 15) stand in a state perpendicular to the upper surface of the table 36, The central operation control unit 50 rotates the rotation motor 84 at an appropriate timing.

In the present embodiment, in the table 36 of the standby position WP, in a state in which all the stack pins 37 are erected and in a state in which all the pin holding bodies 82 are erected on the upper surface of the table 36 . It can also be set as the movement condition to the stack position SP.

Next, the pin holding mechanism 90 for integration is demonstrated. 12 and 13 , the pin holding mechanism 90 is attached to the suction part 24 at the time of integration in this embodiment, and is attached to the pin aggregate 15 from the upper side of the pin aggregate 15 . It is installed so that it can be accessed and removed. The pin holding mechanism 90 at the time of integration in this embodiment has the vertical movement mechanism 92, the rotation mechanism 94, and the pin holding body 98. As shown in FIG.

The vertical movement mechanism 92 is for making the pin support body 98 movable in the height direction of the pin assembly body 15, and a fluid cylinder, such as an air cylinder, can be used suitably. The rotation mechanism 94 is attached to the tip (lower end) of the vertical movement mechanism 92, and a fluid cylinder such as an air cylinder rotatable in a horizontal plane can be suitably used. A pin support body 98 is attached to the rotation shaft 96 of the rotation mechanism 94 . That is, the pin support body 98 rotates in a horizontal plane, and can be approached and detached with respect to the pin assembly body 15 . The operations of the vertical movement mechanism 92 and the rotation mechanism 94 are controlled by the central operation control unit 50 . Here, an air cylinder is used as the vertical movement mechanism 92 and the rotation mechanism 94, but another power mechanism spanning a drive chain or a drive belt to a sprocket or pulley rotated by a motor is used as the vertical movement mechanism 92 and It can also be employ|adopted for the rotation mechanism 94.

The operation of the pin holding mechanism 90 for integration will be described with reference to FIGS. 14 to 17 . Here, in order to simplify the explanation, the display of the pin pressing mechanism 80 is omitted in FIGS. 14 to 17 . 14A shows a state immediately after the table 36 on which the stack pins 37 are erected is rotated from the standby position WP to the stack position SP. At this time, the pin holding mechanism 90 for accumulating is in a state in which the vertical movement mechanism 92 is contracted. has been made

Before starting the stacking process of the pin aggregate 15 on the stack pins 37 , the central operation control unit 50 raises the lifting device 60 to lift the pin support body 35 and the stack pin guide plate 39 . raise processing is performed. Simultaneously with this, or immediately before or immediately after, the central operation control unit 50 extends the vertical movement mechanism 92 to move the pin holder 98 away from the suction unit 24 (approaching the pin support body 35) (Fig. 14B).

The central operation control unit 50 then operates the rotating mechanism 94 to rotate the pin holder 98 connected to the rotation shaft 96 of the rotating mechanism 94 toward the side where the pin aggregate 15 is formed ( 15A). Next, the central operation control unit 50 accumulates the heat exchanger fins 14 along the stack fins 37 to form the fin integrated body 15 . At this time, as shown in FIG. 15B, the central operation control part 50 lowers the position of the raising/lowering device 60 gradually, and the heat exchanger fin 14 dropped from the adsorption|suction part 24 is always carried out by the fin support body 98. ) to be accumulated at the waiting landing position.

As shown in Fig. 16A, when the pin aggregate 15 has reached a predetermined accumulation height, the lifting device 60 returns to its original standby position. And as shown in FIG. 16B, the central operation control part 50 rotates the rotation mechanism 94, and makes the pin holding body 98 into the state separated from the pin integrating body 15. As shown in FIG. Before releasing the pin holding body 98 from the pin assembly 15 , the central operation control unit 50 operates the pin pressing mechanism 80 , thereby holding the pin assembly 15 by the pin holding body 82 . It is desirable to press from both sides. Next, as shown in FIG. 17 , the central operation control unit 50 contracts the vertical movement mechanism 92 so that it approaches the suction unit 24 together with the pin holder 98 (pin aggregate 15). ) and send the table 36 from the stack position SP to the buffer position BP.

In this way, by additionally forming the configuration of the pin pressing mechanism 80 and the pin holding mechanism 90 for accumulating, the pin aggregate 15 is stacked and the table 36 is rotated. It is advantageous in that it is possible to prevent the integration state of the

As mentioned above, although this invention was demonstrated in detail based on embodiment, this invention is not limited to embodiment shown above, It goes without saying that many changes can be implemented within the range which does not deviate from the mind of invention. .

In addition, in this embodiment, the measurement of the height dimension of the pin integrated body 15 integrated in the stacker 31 in the stacking position SP is demonstrated with the optical sensor provided in the lifting device 60. However, it is not limited to this form. A form in which a weight sensor for measuring the mass of the pin integrated body 15 is provided instead of the optical sensor and the height dimension of the pin integrated body 15 is calculated by measuring the weight of the pin integrated body 15 may be adopted. .

In addition, in the above embodiment, although the 1st spacer 33A and the 2nd spacer 33B which differ in height are arrange|positioned on the table 36 of the stacker 31, it can also be set as the spacer of the same height. In addition, a form in which the stack pin holder 38 and the pin support member 35 are directly disposed on the upper surface of the table 36 may be adopted without arranging the first spacer 33A and the second spacer 33B. . In the case of this form, what is necessary is just to raise the pin support body 35 by the raising/lowering device 60 in the stacking position SP. In addition, in the take-out position RP, a lifter (not shown) for lifting the pin support body 35 with the pin integrated body take-out device 40 is arranged, and the pin support body 35 is lifted from the upper surface of the table 36 by the lifter. What is necessary is to form a gap (S) for entering the lower clamping part (42) by lifting it. The operation of the lifter may be controlled by the central operation control unit 50 .

In addition, in the present embodiment, the step of inserting the guide rod into the through hole into which the stack pin 37 of the pin integrated body 15 is not inserted is performed at the buffer position BP, but this step may be omitted. In this case, as shown in FIG. 18, when the stack pins 37 are pulled out from the pin aggregates 15 to separate the stack pins 37 and the pin aggregates 15, the pin aggregates 15 You may make it attachment of the guide rod GR together with the guide rod inserter GRM of a furnace.

When the stack pin 37 is pulled out from the pin aggregate 15 to separate the stack pin 37 and the pin aggregate 15 , the guide rod is inserted by the guide rod inserter (GRM) into the pin aggregate 15 . It becomes possible to abbreviate|omit the buffer position BP by making it attach|wearing GR together. Thereby, it is advantageous at the point which can suppress the manufacturing cost of the fin integrated body manufacturing apparatus 100 of fins for heat exchangers. In addition, the process of attaching the guide rod GR to the fin assembly 15 may be performed concurrently with the process of attaching the refrigerant pipe to the fin assembly 15 .

In addition, in 2nd Embodiment, although the form comprised by the pin press body 82, the rotation motor 84 which rotates this as the pin press mechanism 80, and the central operation control part 50, is demonstrated, but this form It is not limited.
