Japanese Patent No. 5360731

In the prior art, an operator takes out an aggregate in which a plurality of heat exchanger fins 113 are integrated up to a predetermined height along the stack pin 129 of the stacker 126 from the stacker 126. For this reason, there has been a strong demand for improving work efficiency and eliminating work mistakes in the work of removing the aggregate from the stacker 126.

Therefore, the present invention has been made to solve the above-mentioned problems, and an object thereof is to perform a series of operations from press working of heat exchanger fins to taking out an aggregate of heat exchanger fins fully automatically to improve work efficiency. It is an object of the present invention to provide a fin aggregate manufacturing apparatus for fins for a heat exchanger, which enables improvement and elimination of work mistakes.

As a result of diligent research, the applicant came up with a structure that can achieve the above objectives. That is, the present invention comprises a press device formed by pressing a thin metal plate to form a heat exchanger fin having a notch or a through hole through which a heat exchange tube is inserted, and the press device formed by the press device. A plurality of stack pins that enter the notch or the through hole to collect the heat exchanger fins, and the table erected so as to be removable and the heat exchanger fins formed by the press device are collected. Between the stack position where the fin aggregate is obtained, the take-out position where the fin aggregate and the stack pin, which have reached the predetermined accumulation height at the stack position, are taken out from the table, and the standby position which stands by at the position immediately before the stack position. Then, at the table circulation device for circulating and moving the table and the take-out position, the fin aggregate and the stack pin are taken out integrally from the table, and the stack pin is separated from the taken-out fin aggregate and separated. It is a fin aggregate manufacturing apparatus for heat exchanger fins, comprising: a fin aggregate take-out device for re-standing the stacked pins on the table at the standby position.

By adopting this configuration, a series of operations from pressing the heat exchanger fins to taking out the integrated heat exchanger fins can be performed fully automatically. This makes it possible to improve work efficiency and eliminate work mistakes caused by human work.

Further, an integrated height sensor that detects that the accumulated height of the fin integrated body at the stack position has reached a predetermined integrated height, and that the stack pin is erected on the table at the standby position. The table circulation device further includes a stack pin standing confirmation means for confirmation, and the table circulation device includes a rotation drive device and an operation control unit that executes drive control of the rotation drive device, and the operation control unit includes. The stacking height sensor detects that the stacking height of the fin stack has reached a predetermined stacking height, and the stack pin standing confirmation means stands the stack pin on the table at the standby position. It is preferable to drive the rotary drive device to control the table to move to the next position when it is confirmed that the device is used.

According to this configuration, the integrated height of the aggregate of heat exchanger fins supplied from the press device and inserted through the stack pin can be made uniform, and the heat exchanger fins supplied from the press device can be ensured. It can be inserted through the stack pin, and it is possible to prevent the occurrence of defective fin aggregates.

Further, a fin support for supporting the bottom surface of the heat exchanger fin is provided on the upper surface of the table so as to cross the plane region of the table, and the fin support is placed on the stack pin at the stack position. It is preferable that the elevating device for sliding and moving in the height direction of the table is provided at a side position of the table and at a position below the table.

As a result, when the heat exchanger fins supplied from the press device are inserted through the stack pin, the drop from the upper end of the stack pin to the fin support is significantly larger than the drop from the upper end of the stack pin to the upper surface of the table. This can be reduced to prevent deformation of the heat exchanger fins, which also contributes to improving the quality of the heat exchanger fin aggregate.

Further, at the end of the press device on the side of the stack position, an integrated fin support mechanism that supports the fin aggregate at the landing position of the heat exchanger fins when the fin aggregate is integrated is attached to the fin aggregate. On the other hand, it is preferable that it is provided so as to be able to move in contact with each other.

Further, the integrated fin support mechanism includes a fin support body that supports the fin integrated body, and a vertical movement mechanism that moves the fin support body in the height direction from an end portion of the press device on the side of the stack position. It is more preferable to have a rotation mechanism attached to the tip of the vertical movement mechanism and rotating the fin support body in a horizontal plane.

As a result, when the fins are integrated, the heat exchanger fins can be integrated along the stack pins. In addition, since the fin support mechanism at the time of integration can be moved in contact with and detached from the fin aggregate, it is possible to retract the fin support mechanism at the time of integration from the fin aggregate after accumulating the fin aggregate at the stack position. The fin support mechanism does not get in the way when moving the table from the stack position to the next position.

Further, it is preferable that the table is located at both ends of the fin aggregate and further has a fin pressing mechanism for pressing the fin aggregate.

Further, the fin pressing mechanism has a fin pressing body that presses the fin integrated body, and a switching control unit that switches between a pressed state and a non-pressed state of the fin integrated body by the fin pressing body. At the stack position, the switching control unit puts the fin holding body in a non-holding state and rotates the table from the stack position to the taking-out position until the accumulation of the fin integrated bodies is completed. Before, the fin holding body is put into a pressed state, and at the taking-out position, only the fin holding body on the side of the fin integrated taking-out device is put into a non-holding state, and the fin holding body is moved from the standby position to the stack position. In the meantime, it is more preferable to put all the fin pressing bodies in a non-pressing state.

As a result, it is possible to prevent the fin aggregate from collapsing when the table on which the fin aggregate is placed rotates. Further, by setting the fin holding body on the fin collecting device taking-out position to the non-holding state at the taking-out position, the fin holding body does not interfere with the work when taking out the fin collecting body.

According to the present invention, a series of operations from pressing the heat exchanger fins to taking out the fin aggregate in which the heat exchanger fins are laminated can be performed fully automatically, and the manufacturing efficiency of the fin aggregate can be improved. At the same time, it becomes possible to prevent the occurrence of defective products due to human error.

The fin integrated manufacturing apparatus for the fins for the heat exchanger according to the present embodiment will be described in detail based on the embodiment.

(First Embodiment)
1 and 2 show the overall configuration of the fin integrated manufacturing apparatus for heat exchanger fins according to the present embodiment. The fin aggregate manufacturing apparatus 100 for heat exchanger fins (hereinafter, simply referred to as fin aggregate manufacturing apparatus 100) in the present embodiment is a press apparatus for forming heat exchanger fins 14 from a thin plate 12 supplied from a material supply unit 10. 20 The operation control unit 50 is provided.

The material supply unit 10 has an anchorer 10A in which an unprocessed metal thin plate 12 such as aluminum is wound in a coil shape, and a feeder 10B for unwinding the thin plate 12 from the anchorer 10A at a predetermined timing. Since the material supply unit 10 in the present embodiment may adopt a known configuration, detailed description here will be omitted.

In the press device 20, the mold device 22 is arranged inside, the thin plate 12 supplied from the material supply unit 10 is press-processed, and the metal strip 13 having a notch or a through hole through which the heat exchange tube is inserted is formed. The fin 14 for the heat exchanger is formed through the above. The mold device 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 as to be movable in contact with the other. .. The metal strip 13 sent out from the mold device 22 is separated into pieces by an inter-row slit device and a cutoff device (not shown) in each of the width direction and the sending direction, and is formed in the heat exchanger fin 14. The heat exchanger fin 14 thus formed is sucked and held by a suction portion 24 provided at the most downstream position of the mold device 22, and the table circulation device 30 provided at an adjacent position on the downstream side of the press device 20. Is sent to.

In the table circulation device 30 of the present embodiment, the table 36 is attached to the upper surface of the table holding plate 34, which can be rotated by the motor 32 as a rotation drive device, along the rotation direction. The drive control of the motor 32 is executed by the central motion control unit 50.

The table holding plate 34 is formed in a disk shape having a rotation axis at the center. The table 36 is attached to the table holding board 34 at four points along the outer circumference of the table holding board 34 at equal intervals (90 degree intervals about the axis of rotation in the horizontal plane). Since table mounting holes (not shown) are formed at predetermined intervals on the upper surface of the table holding board 34 of the present embodiment along the outer peripheral edge, the table 36 is taken at an arbitrary position of the table holding board 34. It can be attached. The rotating shaft of the table holding plate 34 is directly connected to the output shaft of the motor 32 via a speed reducer or directly.

When the motor 32 is rotationally driven by the instruction of the central operation control unit 50, the table holding board 34 rotates around the axis of rotation, and each table 36 has four positions, a stack position SP, a buffer position BP, a take-out position RP, and a standby position WP. It will be circularly moved within the position of.

The stack position SP (stack position) is a position directly below the suction portion 24 of the press device 20 and has a predetermined height along the stack pin 37 in which the heat exchanger fins 14 from the press device 20 are erected on the table 36. It is a position to obtain the fin integrated body 15 of the heat exchanger fins 14 by accumulating them on the stacker 31 (table 36) until the dimensions are reached. The buffer position BP (buffer position) is a position for sending out the fin integrated body 15 of the heat exchanger fins 14 accumulated in the stacker 31 at a predetermined integrated height at the stack position SP from the stack position SP and making them stand by.

The take-out position RP (take-out position) is a position immediately after the buffer position BP, and the fin integrated body 15 having a predetermined stacking height at the stack position SP is sent out together with the stack pin 37, and the fin integrated body 15 is taken out. Is. The standby position WP (standby position) is a position following the take-out position RP, and is a position in which the stack pin 37 stands by again at a predetermined position on the table 36 at a position immediately before the stack position SP.

As shown in FIGS. 3 and 4, the first spacer 33A and the stack pin holder 38 are scatteredly arranged on the upper surface of the table 36 of the stacker 31 in the present embodiment. A fin support 35 having both ends protruding outward of the table 36 is attached to the upper surface of the first spacer 33A so as to cross the plane region of the table 36. The second spacer 33B and the stack pin guide plate 39, each of which has a hollow (through hole) in the insertion plane position of the stack pin 37, are placed on the upper surface of the stack pin holder 38 in the order described. As shown in FIG. 3, the first spacer 33A is provided so as to sandwich the second spacer 33B at a lateral position of the second spacer 33B.

Further, a plurality of stack pins 37 can be inserted and removed from the stack pin holder 38. To confirm whether or not the stack pin 37 is erected with respect to the stack pin holder 38, it is confirmed that the operation control program of the fin aggregate take-out device 40, which will be described later, has executed a series of operations without causing an error. It is possible by confirming (corresponding to the stack pin standing confirmation means). Here, the series of operations is that after the fin integrated body 15 is pulled out from the stack pin holder 38 together with the stack pin 37, the fin integrated body 15 and the stack pin 37 are separated, and only the stack pin 37 is returned to the stack pin holder 38. Refers to the processing up to.

As another specific example of the stack pin standing confirmation means, a stack pin sensor may be arranged on the stack pin holder 38. In this case, the confirmation information of the standing state of the stack pin 37 on 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 dropped from the suction portion 24 of the press device 20 onto the stack pin 37, and the heat exchanger fins 14 are sequentially integrated along the stack pin 37 to form the fin integrated body 15. Become. The fin integrated body 15 is supported by the first spacer 33A and the fin support 35 in a state where the bottom surface thereof has a gap S between the bottom surface and the top surface of the table 36.

Further, the stack position SP of the present embodiment is provided with an elevating device 60 for moving the fin support 35 in the height direction of the stack pin 37 (see FIGS. 1 and 2). The elevating device 60 is located below the moving surface of the stacker 31 at a position outside the plane region of the stacker 31 (table 36), which is a lateral position of the stacker 31 (in this embodiment, a position below the table holding plate 34). ). The elevating device 60 in the present embodiment is in the form of elevating and lowering while the fin support 35 is held by a plate-shaped body, but it is also possible to have a configuration in which both ends of the fin support 35 are gripped by a grip portion that can be elevated and lowered. .. This is convenient in that the fin support 35 and the fin integrated body 15 can be slid and moved along the stack pin 37 in a stable state.

In the elevating device 60 in the present embodiment, the elevating operation is controlled by the central operation control unit 50 in one cycle from the time when the stacker 31 is sent to the stack position SP to the time when the stacker 31 is sent out to the buffer position BP. Further, in order to detect that the height of the fin integrated body 15 integrated in the fin support 35 has reached a preset height in either the elevating device 60 or the fin integrated body taking-out device 40 described later. An optical sensor (not shown) is provided. As the optical sensor, a known configuration of a measurement light irradiation unit and a light receiving sensor can be adopted. When the optical sensor in the present embodiment detects that the measured light emitted from the measurement light irradiation unit is blocked by the fin integrated body 15 when the integrated height of the fin integrated body 15 reaches a predetermined height. , A mode is adopted in which an integrated height arrival detection signal is transmitted to the central motion control unit 50.

At the start of the integration process when the heat exchanger fins 14 are integrated in the stacker 31 along the stack pin 37 at the stack position SP, the central operation control unit 50 puts the fin support 35 and the stack pin guide plate 39 on the stack pin 37. The operation of the elevating device 60 is controlled so as to be raised along the line. The fin support 35 and the stack pin guide plate 39 are raised to a position near the upper end portion of the stack pin 37 and to an accumulation start position near the upper end portion of the stack pin 37.

In this way, the heat exchanger fins 14 are released from the suction portion 24 by bringing the position of the fin support 35 at the time when the stacking is started along the stack pin 37 at the stack position SP closer to the suction portion 24 of the press device 20. The head of the heat exchanger fin 14 can be reduced. Therefore, the deformation of the heat exchanger fin 14 when the heat exchanger fin 14 released from the suction portion 24 lands on the fin support 35 is prevented. Furthermore, by guiding the tip (upper end) of the stack pin 37 at a position as high as possible, the plane position of the tip of the stack pin 37 can be aligned with the correct position.

The central motion control unit 50 gradually slides the height positions of the fin support 35 and the stack pin guide plate 39 according to the height of the fin integrated 15 of the heat exchanger fin 14 on the stack pin 37. The operation of the elevating device 60 is controlled so as to approach the table 36 side. Further, when the central motion control unit 50 determines that the height of the fin integrated body 15 to the stack pin 37 has reached a predetermined integrated height by receiving the integrated height arrival detection signal transmitted from the optical sensor, the elevating device The 60 is lowered to the initial position, which is a position below the moving surface of the stacker 31. As a result, the elevating device 60 does not interfere with the table circulation device 30 when the table circulation device 30 is operated.

In the central operation control unit 50, the stack pin 37 stands on all the stack pin holders 38 of the table 36 in the standby position WP, and the stack height of the fin stack 15 reaches a predetermined stack height set in advance. When it is detected that the motor 32 is installed, a process of 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 out to the next position (position). Here, the central operation control unit 50 (corresponding to the stack pin standing confirmation means) confirms that the operation control program of the fin integrated take-out device 40 has executed a series of operations without causing an error, thereby waiting. It is confirmed that the stack pins 37 are erected on all the stack pin holders 38 of the table 36 at the position WP.

In the present embodiment, the process of inserting the guide rod or the refrigerant pipe (neither of them) into the through hole through which the stack pin 37 is not inserted is central to the fin integrated body 15 in the table 36 of the buffer position BP. It is executed by the operation control unit 50. By inserting the guide rod or the refrigerant pipe into the fin integrated body 15 in which the stack pin 37 is inserted in this way, the fin integrated body 15 when the table 36 rotates from the buffer position BP to the take-out position RP. Can be prevented from collapsing.

The fin stack 15 along the stack pin 37 is stacked at a predetermined stack height in the stacker 31 sent out from the buffer position BP to the take-out position RP. The central operation control unit 50 issues an instruction to the fin aggregate take-out device 40 deployed at the take-out position RP to take out the fin aggregate 15 together with the stack pin 37 from the table 36 of the stacker 31 at the take-out position.

As shown in FIGS. 4 and 5, the fin integrated take-out device 40 in the present embodiment has an upper end holding portion 41 that sandwiches the upper end portion of the stack pin 37 and a lower end holding portion 42 that sandwiches the lower end portion of the stack pin 37. It has a vertical movement mechanism 43 for moving the upper end holding portion 41 and the lower end holding portion 42 up and down, and a horizontal moving mechanism 44 for moving the upper end holding portion 41 and the lower end holding portion 42 in the horizontal direction. Here, the upper end portion and the lower end portion of the stack pin 37 are concepts including the periphery of the upper end portion and the lower end portion of the stack pin 37. The operation of the fin integrated take-out device 40 is controlled by the central operation control unit 50. Further, a fin support 46 is attached to the upper side of the lower end holding portion 42.

The horizontal movement mechanism 44 is operated according to the instruction from the central motion control unit 50 to bring the fin integrated take-out device 40 closer to the fin integrated body 15 (FIG. 5A). The central operation control unit 50 continuously advances the upper end holding portion 41 and the lower end holding portion 42 in an open state to the position of the stack pin 37, closes the upper end holding portion 41, and holds only the upper end portion of the stack pin 37 (FIG. FIG. 5B). At this time, the bottom surface of the lowermost portion of the fin integrated body 15 is held by the fin support 46.

Next, the central motion control unit 50 operates the vertical movement mechanism 43, raises only the upper end holding portion 41, and pulls out only the stack pin 37 from the stack pin holder 38 (FIG. 5C). Next, the central motion control unit 50 closes the lower end holding portion 42 to sandwich the lower end portion of the stack pin 37, and operates the horizontal movement mechanism 44 to sandwich the upper end portion and the lower end portion of the stack pin 37. 15 is moved away from the other fin aggregates 15 (FIG. 5D).

In this way, the fin integrated body taking-out device 40 sandwiches the upper end portion and the lower end portion of the stack pin 37, respectively, and the fin integrated body 15 inserted through the stack pin 37 is integrated with the stack pin 37 as described in the table 36 ( Pull it out from the stack pin holder 38).

The fin aggregate 15 pulled out from the table 36 together with the stack pin 37 is placed sideways on the conveyor 70 as a transport unit (FIG. 6A). The fin integrated body 15 through which the stack pin 37 is inserted is placed with the stack pin 37 in a state parallel to the upper surface (ground surface) of the conveyor 70. Next, the central motion control unit 50 releases the pinching of the lower end holding portion 42, and moves the lower end holding portion 42 in the direction of separating from the fin integrated body 15 (upper side in FIG. 6B) (FIG. 6B).

Then, as shown in FIG. 6C, the central operation control unit 50 is at a position where the stack pin 37 is not pulled out from the upper end portion of the fin integrated body 15 (a state in which the stack pin 37 is guided in the through hole of the fin integrated body 15). ) Holds the lower end of the stack pin 37 in the lower end holding 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 has been pulled out.

A stack pin guide plate 39 is arranged at a position directly above the stack pin holder 38 in the present embodiment. The stack pin guide plate 39 is provided with a through hole 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. The opening size is formed to be larger than the lower opening size. This allows the stack pin 37 to be correctly returned to its original position. When the stack pin 37 is re-established on the stack pin holder 38 in this way, the stroke amount of the actuating portion such as an actuator (not shown) attached to the arm of the fin integrated take-out device 40 is measured by the actuating portion monitoring means or the actuating portion monitoring means. The central motion control unit 50 is monitoring.

In the present embodiment, the operating unit monitoring means or the central operation control unit 50 that monitors the stroke amount of the operating unit corresponds to the stack pin standing confirmation means. When the measured stroke amount of the operating unit does not reach the predetermined stroke amount, the operating unit monitoring means or the central operation control unit 50 does not normally complete a series of operations in the fin aggregate extraction device 40 (re-stacking of the stack pin). It can be judged that the erection was not done correctly).

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 the integrated height of the fin integrated body 15 in the stack position SP. When it is detected that the height has reached a predetermined integrated height, the motor 32 is driven to circulate and move each stacker 31 in the table circulation device 30 to the next position.

By repeatedly executing the above operations, it is possible to fully automatically perform the process of converting the heat exchanger fins 14 supplied from the press device 20 into the fin integrated body 15 and sequentially sending them to the next process.

As described above, according to the fin integrated manufacturing device 100 for the fins for the heat exchanger in the present embodiment, the table 36 is placed in the stack position by the table circulation device 30, the fin integrated body taking-out device 40, and the central operation control unit 50. While circulating and moving between the SP, the buffer position BP, the take-out position RP, and the standby position WP, the heat exchanger fins 14 sent out from the press device 20 are made into fin aggregates 15 and sequentially sent out to the next position (process). Processing can be performed automatically.

According to the configuration of the fin integrated body manufacturing apparatus 100 for heat exchanger fins in the present embodiment, the fin integrated body 15 for manufacturing the heat exchanger fins 14 and the fin integrated body 15 in which the fin integrated bodies 15 are integrated is formed, and the formed fin integrated body 15 is next. It is possible to automate a series of processes to be sent to the process. This makes it possible to manufacture the fin aggregate 15 of the fins 14 for heat exchangers, which is extremely efficient, without causing problems such as handling mistakes of the fin aggregates 15 due to manual intervention.

(Second Embodiment)
7 and 8 show a fin integrated manufacturing apparatus for heat exchanger fins according to the present embodiment. In the present embodiment, for the same configuration as that of the first embodiment, the reference numerals used in the first embodiment are illustrated, and detailed description thereof will be omitted here. In the present embodiment, the fin pressing mechanism 80 is provided on the upper surface of each table 36, and the fin supporting mechanism for integration is provided on the suction portion 24 which is the end portion of the press device 20 on the side of the stack position SP. It is characteristic that 90 is provided.

The fin holding mechanism 80 is for holding the fin integrated body 15 integrated on the upper surface of the table 36, and is located at both ends of the fin integrated body 15 (both ends in the longitudinal direction when the fin integrated body 15 is viewed in a plan view). ) Is provided so as to hold down the fin aggregate 15. The fin pressing mechanism 80 in the present embodiment has a fin pressing body 82 that abuts against the positions of both ends of the fin collecting body 15 and presses the fin collecting body 15, and the fin collecting body 15 is in a pressed state and is not pressed by the fin pressing body 82. It has a rotation motor 84 as a switching control unit that switches and controls the crowded state. The operation of the rotary motor 84 is controlled by the central operation control unit 50. The rotation motor 84 rotates the fin holding body 82 between a state in which the fin holding body 82 is erected with respect to the upper surface of the table 36 and a state in which the fin holding body 82 is horizontal to the upper surface of the table 36. Switching control is performed between the non-pressed state and the non-pressed state.

The operation of the fin pressing mechanism 80 will be described. 9 to 11 are plan views of a main part for explaining the operation of the fin pressing mechanism 80 at each position. Here, the operation of the fin pressing mechanism 80 arranged on the table 36 at the stack position SP in FIG. 9 will be described at each position.

At the stack position SP, as shown in FIG. 9, the fin pressing mechanism 80 is in a state where the fin pressing body 82 stands upright in the direction orthogonal to the upper surface of the table 36. By making the fin holding body 82 stand upright on the upper surface of the table 36 in this way, the fin holding body 82 does not get in the way when the fin collecting bodies 15 are piled up.

When the height of the fin integrated body 15 integrated on the upper surface of the table 36 at the stack position SP reaches a preset height, the central motion control unit 50 is as shown in the table 36 in the SP of FIG. The rotation motor 84 is operated to rotate the fin holding body 82 so as to be parallel to (horizontally) the upper surface of the table 36. By pressing the fin aggregate 15 with the fin retainer 82 so as to sandwich the fin aggregate 15 from both ends of the fin aggregate 15 in this way, it is possible to prevent the fin aggregate 15 from collapsing when the table 36 is rotated. can.

While the table 36 rotates and waits at the buffer position BP, as shown in the table 36 in FIG. 10, the fin holding body 82 maintains the state in which both end positions of the fin integrated body 15 are sandwiched. Will be done. At the buffer position BP, the quality of the fin integrated body 15 can be confirmed, the stack pin 37 can be pulled out, and the guide rod or the refrigerant pipe can be inserted. Then, even when rotating from the buffer position BP to the take-out position RP, the state in which both end positions of the fin integrated body 15 are sandwiched by the fin holding body 82 is maintained.

Then, as shown in FIG. 11, in the table 36 at the take-out position RP, the central operation control unit 50 operates only the rotation motor 84 of the fin holding mechanism 80 on the side of the fin integrated body taking-out device 40, and the fin holding body 82 Is placed upright on the upper surface of the table 36. By doing so, the fin holding body 82 does not get in the way when the fin collecting body 15 is taken out by the fin collecting body taking out device 40 at the taking out position RP, which is convenient.

Then, when the extraction processing of all the fin integrated bodies 15 in the extraction position RP is completed, the central operation control unit 50 moves the table 36 of the extraction position RP to the standby position WP. In the table 36 that has moved to the standby position WP, the central motion control unit 50 is rotated so that all the fin holding bodies 82 (on both sides of the fin integrated body 15) stand upright on the upper surface of the table 36 in an orthogonal state. The dynamic motor 84 is rotated at an appropriate timing.

In the present embodiment, in the table 36 of the standby position WP, it is stacked that all the stack pins 37 are erected and all the fin holding bodies 82 are erected on the upper surface of the table 36. It can also be a condition for moving to the position SP.

Next, the fin support mechanism 90 for integration will be described. As shown in FIGS. 12 and 13, the fin support mechanism 90 at the time of integration in the present embodiment is attached to the suction portion 24 and is provided so as to be movable in contact with and detachable from the upper side of the fin accumulation body 15. The integrated fin support mechanism 90 in the present embodiment has a vertical movement mechanism 92, a rotation mechanism 94, and a fin support body 98.

The vertical movement mechanism 92 is for making the fin support body 98 movable in the height direction of the fin integrated body 15, and a fluid cylinder such as an air cylinder can be preferably used. 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 that can rotate in a horizontal plane can be preferably used. A fin support 98 is attached to the rotation shaft 96 of the rotation mechanism 94. That is, the fin support body 98 rotates in the horizontal plane and can move in contact with the fin integrated 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 in which a drive chain or a drive belt is hung on a sprocket or pulley rotated by a motor is applied to the vertical movement mechanism 92 and the rotation mechanism 94. It can also be adopted.

The operation of the fin support mechanism 90 for integration will be described with reference to FIGS. 14 to 17. Here, for the sake of simplicity, the display of the fin pressing mechanism 80 is omitted in FIGS. 14 to 17. FIG. 14A shows a state immediately after the table 36 on which the stack pin 37 is erected has rotated from the standby position WP to the stack position SP. At this time, the fin support mechanism 90 for integration is in a state in which the vertical movement mechanism 92 is contracted, and the rotation mechanism 94 is in a state in which the fin support body 98 is positioned on the side opposite to the formation side of the fin accumulation body 15.

Before starting the stacking process of the fin integrated body 15 on the stack pin 37, the central motion control unit 50 raises the elevating device 60 to lift the fin support 35 and the stack pin guide plate 39. At the same time, immediately before or immediately after this, the central motion control unit 50 extends the vertical movement mechanism 92 to separate the fin support 98 from the suction unit 24 (approach the fin support 35) (FIG. 14B).

Next, the central motion control unit 50 operates the rotation mechanism 94 to rotate the fin support 98 connected to the rotation shaft 96 of the rotation mechanism 94 to the side where the fin integrated body 15 is formed (FIG. 15A). Next, the central motion control unit 50 integrates the heat exchanger fins 14 along the stack pins 37 to form the fin integrated body 15. At this time, the central motion control unit 50 gradually lowers the position of the elevating device 60 as shown in FIG. 15B, and the heat exchanger fin 14 dropped from the suction unit 24 is always placed at the landing position where the fin support body 98 stands by. I am trying to accumulate.

As shown in FIG. 16A, when the fin integrated body 15 reaches a predetermined integrated height, the elevating device 60 returns to the original standby position. Then, the central motion control unit 50 rotates the rotation mechanism 94 as shown in FIG. 16B so that the fin support body 98 is separated from the fin integrated body 15. Before the fin support body 98 is separated from the fin integrated body 15, it is preferable that the central motion control unit 50 operates the fin holding mechanism 80 so that the fin holding body 82 presses the fin collecting body 15 from both sides. Next, as shown in FIG. 17, the central motion control unit 50 contracts the vertical movement mechanism 92 to approach the suction unit 24 together with the fin support 98 (separate from the upper position of the fin aggregate 15), and stacks the table 36. It is sent from the position SP to the buffer position BP.

As described above, by additionally providing the fin holding mechanism 80 and the fin support mechanism 90 for integration, the integrated state of the fin integrated body 15 is disturbed when the fin integrated body 15 is integrated and when the table 36 is rotated. It is convenient in that it can prevent.

Although the present invention has been described in detail above based on the embodiments, the present invention is not limited to the embodiments shown above, and many modifications can be made without departing from the spirit of the invention. Of course. For example, in the present embodiment, the configuration in which the four tables 36 are attached to the table holding plate 34 is illustrated, but at least three tables 36 may be attached in the circumferential direction of the table holding plate 34. That is, the table circulation device 30 may have at least a stack position SP, a take-out position RP, and a standby position WP.

Further, in the present embodiment, the measurement of the height dimension of the fin integrated body 15 integrated in the stacker 31 at the stack position SP is described by the optical sensor provided in the elevating device 60. Not limited to. It is also possible to adopt a form in which a weight sensor for measuring the mass of the fin integrated body 15 is provided instead of the optical sensor, and the height dimension of the fin integrated body 15 is calculated by measuring the weight of the fin integrated body 15.

Further, in the above embodiment, the first spacer 33A and the second spacer 33B having different heights are arranged on the table 36 of the stacker 31, but spacers having the same height can also be used. Further, it is also possible to adopt a form in which the stack pin holder 38 and the fin support 35 are directly arranged on the upper surface of the table 36 without disposing the first spacer 33A and the second spacer 33B. In the case of this embodiment, the fin support 35 may be raised by the elevating device 60 at the stack position SP. Further, in the take-out position RP, a lifter (not shown) for lifting the fin support 35 is arranged in the fin integrated body take-out device 40, and the fin support 35 is lifted from the upper surface of the table 36 by the lifter to allow the lower end holding portion 42 to enter. It suffices to form a gap S for the purpose. The operation of the lifter can be controlled by the central operation control unit 50.

Further, in the present embodiment, the step of inserting the guide rod into the through hole into which the stack pin 37 of the fin integrated body 15 is not inserted is executed at the buffer position BP, but this step can be omitted. In this case, as shown in FIG. 18, when the stack pin 37 is pulled out from the fin integrated body 15 to separate the stack pin 37 and the fin integrated body 15, the guide rod is inserted into the fin integrated body 15 by the guide rod insertion machine GRM. GR may be attached at the same time.

For the extraction of the stack pin 37 and the insertion process of the guide rod GR using the guide rod insertion machine GRM, a known method as shown in FIGS. 18A, 18B, and 18C can be used. When the stack pin 37 is pulled out from the fin integrated body 15 to separate the stack pin 37 and the fin integrated body 15, the guide rod GR is also attached to the fin integrated body 15 by the guide rod inserting machine GRM. If this is the case, the buffer position BP can be omitted. This is advantageous in that the manufacturing cost of the fin integrated manufacturing apparatus 100 for the fins for the heat exchanger can be suppressed. Further, the step of mounting the guide rod GR on the fin integrated body 15 can be performed together with the step of mounting the refrigerant pipe on the fin integrated body 15.

Further, in the second embodiment, the fin pressing mechanism 80 includes a fin pressing body 82, a rotation motor 84 for rotating the fin pressing body 82, and a central motion control unit 50. Not limited. A configuration is adopted in which the central motion control unit 50 switches between the pressed state and the non-pressed state of the fin integrated body 15 by moving the fin pressing body 82 to and from both sides of the fin integrated body 15 by the switching control unit. You can also do it.

Then, in the second embodiment, the configuration having the fin pressing mechanism 80 and the integrated fin supporting mechanism 90 is described, but only one of the fin pressing mechanism 80 and the integrated fin supporting mechanism 90 is the first. It can also be added to the embodiment.

Further, a configuration in which the configuration in the present embodiment and the configurations in the above various modifications are appropriately combined can be adopted.
