Patent No. 5360731

In the conventional technique, the worker takes out the stack formed by stacking the plurality of heat exchanger fins 113 along the stack pin 129 of the stacker 126 to a predetermined height from the stacker 126. Therefore, there has been a strong demand for improving work efficiency and eliminating work mistakes in the work of taking out the stack from the stacker 126.

Therefore, the present invention has been made to solve the above problems, and the purpose thereof is to perform a series of operations from pressing of the heat exchanger fins to removal of the heat exchanger fin aggregates in a fully automatic manner to improve work efficiency. It is an object of the present invention to provide a fin integrated body manufacturing apparatus for heat exchanger fins, which enables improvement and elimination of work mistakes.

The applicant has conducted research earnestly and, as a result, has come up with a configuration that can achieve the above-mentioned purpose. That is, the present invention is a press device that forms a fin for a heat exchanger having a cutout or a through hole through which a heat exchange tube is inserted by pressing a thin metal plate, and the press device formed by the press device. A plurality of stack pins that enter the cutout portion or the through hole to accumulate the heat exchanger fins are provided so that the stackable table is erected and the heat exchanger fins formed by the pressing device are integrated. Between a stack position for obtaining a fin stack, a take-out position for integrally taking out the fin stack and the stack pin having a predetermined stacking height at the stack position from the table, and a standby position for standing by immediately before the stack position. And a table circulating device for circulatingly moving the table, and at the take-out position, the fin stack and the front part from the table. A fin stack take-out device for taking out the stack pin as a unit, separating the stack pin from the taken-out fin stack, and re-standing the separated stack pin on the table at the standby position. A fin integrated body manufacturing apparatus for a heat exchanger fin.

By adopting this configuration, a series of operations from pressing the heat exchanger fins to taking out the heat exchanger fin aggregates can be performed fully automatically. As a result, work efficiency can be improved, and work errors due to human work can be eliminated.

Further, a stacking height sensor for detecting that the stacking height of the fin stack at the stacking position has reached a predetermined stacking height, and the stacking pin is erected on the table at the standby position. Stack pin standing confirmation means for confirming is further provided, and the table circulation device has 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 stacking body has reached a predetermined stacking height, and the stacking pin standing confirmation means sets the stacking pin upright on the table at the standby position. If it is confirmed that the rotation driving device is driven, it is preferable to drive the rotation driving device to control the table to move to the next position.

According to this configuration, the stacking height of the heat exchanger fin assembly supplied from the press machine and inserted into the stack pins can be made uniform, and the heat exchanger fins supplied from the press machine can be reliably secured. It is possible to insert the stack pin into the stack pin, and it is possible to prevent defective products from being generated in the fin assembly.

In addition, a fin support that supports a bottom surface of the heat exchanger fins is provided on an upper surface of the table in an arrangement that crosses a plane area of the table, and the fin support is provided at the stack position. It is preferable that an elevating device that slides in the height direction is provided at a side position of the table and a position below the table.

As a result, when the heat exchanger fins supplied from the press machine are inserted into the stack pins, the drop from the top end of the stack pin to the fin support is greatly reduced compared to the drop from the top end of the stack pin to the top surface of the table. The heat exchanger fins can be prevented from being deformed, and the quality of the heat exchanger fin assembly can be improved.

Further, at the end of the pressing device on the side of the stack position, a fin supporting mechanism at the time of stacking that supports the fin stack at the landing position of the fins for the heat exchanger at the time of stacking the fin stack is installed on the fin stack. It is preferably provided so as to be able to move toward and away from it.

With these, the fins for the heat exchanger can be integrated in a state of being aligned along the stack pins during the integration of the fin assembly. Further, since the fin supporting mechanism at the time of stacking can be moved toward and away from the fin stack, it is possible to retract the fin supporting mechanism at the time of stacking from the fin stack after stacking the fin stack at the stacking position. Therefore, when the table is moved from the stack position to the next position, the fin supporting mechanism does not get in the way during stacking.

Further, it is preferable that the table further includes a fin holding mechanism that is located at both end portions of the fin stack and that holds down the fin stack.

Further, the fin pressing mechanism includes a fin pressing body that presses down the fin stack, and a switching control unit that controls switching between a pressed state and a non-pressed down state of the fin stack by the fin pressing body. At the stack position, the switching control unit causes the fin pressing body to be in a non-pressed state until the stacking of the fin stacks is completed, and rotates the table from the stack position to the take-out position. Before that, the fin pressing body is put into a pressed state, and at the take-out position, only the fin holding body on the side of the fin stack take-out device is put into a non-pressed state and moved from the standby position to the stack position. In the meantime, it is more preferable that all the fin pressing bodies are in the non-pressed state.

With these, it is possible to prevent the fin assembly from collapsing when the table on which the fin assembly is placed rotates. Further, at the take-out position, the fin pressing body on the side of the fin stack take-out device is in a non-pressed state, so that the fin press body does not interfere with the work when the fin stack is taken out.

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

(1st Embodiment)
1 and 2 show the overall configuration of a fin integrated body manufacturing apparatus for heat exchanger fins according to the present embodiment. A fin integrated body manufacturing apparatus 100 for a heat exchanger fin according to the present embodiment (hereinafter, simply referred to as a fin integrated body manufacturing apparatus 100) is a pressing apparatus for forming a heat exchanger fin 14 from a thin plate 12 supplied from a material supply unit 10. 20, a table circulation device 30 that conveys the fin assembly 15 formed by accumulating the heat exchanger fins 14, a fin assembly extraction device 40 that extracts the fin assembly 15, and a central control unit for controlling these operations. And an operation control unit 50.

The material supply unit 10 has 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. Since the material supply unit 10 in the present embodiment may have a known configuration, detailed description thereof will be omitted here.

The pressing device 20 has a mold device 22 arranged therein, presses the thin plate 12 supplied from the material supply part 10, and forms a metal strip 13 having a notch or a through hole through which a heat exchange tube is inserted. After that, the heat exchanger fins 14 are formed. The mold device 22 has an upper die set 22A and a lower die set 22B, and one of the upper die set 22A and the lower die set 22B is provided so as to be movable toward and away from the other. . The metal strip 13 sent out from the mold device 22 is formed into the heat exchanger fins 14 in each of the width direction and the sending direction by an inter-row slit device and a cut-off device (not shown). The heat exchanger fins 14 thus formed are adsorbed and held by the adsorbing portion 24 provided at the most downstream position of the die device 22, and the table circulation device 30 provided at a position adjacent to the downstream side of the press device 20. Sent to.

The table circulation device 30 according to the present embodiment has a table 36 mounted on the upper surface of a table holding plate 34 that can be rotated by a motor 32 as a rotation drive device along the rotation direction. The drive control of the motor 32 is executed by the central operation control unit 50.

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

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

The stack position SP (stack position) is a position directly below the adsorption 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 where the fin stack 15 of the heat exchanger fins 14 is obtained by stacking the stacker 31 (table 36) until the size is reached. The buffer position BP (buffer position) is a position for sending out the fin assembly 15 of the heat exchanger fins 14 accumulated in the stacker 31 at the stacking position SP to a predetermined stacking height from the stack position SP and making it stand by.

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

As shown in FIGS. 3 and 4, the first spacers 33A and the stack pin holders 38 are arranged in a scattered manner on the upper surface of the table 36 of the stacker 31 in this embodiment. On the upper surface of the first spacer 33A, there is attached a fin support 35 whose both end portions are protruded outside the table 36 so as to cross the plane 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 insertion plane position of the stack pin 37 is hollow (through hole) are placed in the order described. As shown in FIG. 3, the first spacer 33A is provided at a position lateral to the second spacer 33B so as to sandwich the second spacer 33B.

Also, a plurality of stack pins 37 can be inserted into and removed from the stack pin holder 38. Whether or not the stack pin 37 is erected with respect to the stack pin holder 38 is confirmed by confirming that the operation control program of the fin integrated body extracting device 40, which will be described later, executes a series of operations without causing an error. It is possible to confirm by (a stack pin standing confirmation means). Here, the series of operations means that the fin stack 15 and the stack pin 37 are removed from the stack pin holder 38, then the fin stack 15 and the stack pin 37 are separated, and only the stack pin 37 is returned to the stack pin holder 38. Up to processing.

As another specific example of the stack pin standing confirmation means, a stack pin sensor may be provided 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 dropped onto the stack pins 37 from the adsorption portion 24 of the press device 20, and the heat exchanger fins 14 are sequentially stacked along the stack pins 37 to form the fin stack 15. Become. The fin stack 15 is supported by the first spacer 33A and the fin support 35 with the bottom surface thereof having a gap S between it and the top surface of the table 36.

Further, an elevating device 60 for moving the fin support 35 in the height direction of the stack pin 37 is provided at the stack position SP of the present embodiment (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 area of the stacker 31 (table 36) which is a lateral position of the stacker 31 (below the table holding plate 34 in the present embodiment). ). The elevating device 60 in the present embodiment is a mode in which the fin support body 35 is raised and lowered while being held by a plate-shaped body, but it is also possible to have a configuration in which both end portions of the fin support body 35 are grasped by graspable portions that can be raised and lowered. . This is advantageous in that the fin support 35 and the fin assembly 15 can be slid along the stack pin 37 in a stable state.

The lifting / lowering device 60 in the present embodiment controls the lifting / lowering operation by the central operation control unit 50 with one cycle from the time of sending the stacker 31 to the stack position SP to the time of sending the stacker 31 to the buffer position BP. In addition, in order to detect that the height of the fin stack 15 accumulated on the fin support 35 has reached a preset height in either the lifting device 60 or the fin stack extraction device 40 described later. (Not shown) is provided. The optical sensor can employ a known configuration including a measurement light irradiation unit and a light receiving sensor. When the optical sensor according to the present embodiment detects that the measurement 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. , The form for transmitting the accumulated height arrival detection signal to the central operation control unit 50 is adopted.

At the start of the stacking process when stacking the heat exchanger fins 14 on the stacker 31 along the stack pins 37 at the stack position SP, the central operation control unit 50 causes the fin support 35 and the stack pin guide plate 39 to move to the stack pins 37. The operation of the elevating device 60 is controlled so as to elevate it. The fin support 35 and the stack pin guide plate 39 are lifted to the stacking start position near the upper end of the stack pin 37 and near the upper end of the stack pin 37.

In this way, the fins for heat exchanger 14 at the stack position SP are released from the suction section 24 by bringing the position of the fin support 35 at the time of starting stacking along the stack pins 37 close to the suction section 24 of the press device 20. The head of the heat exchanger fins 14 thus formed can be reduced. Therefore, deformation of the heat exchanger fins 14 when the heat exchanger fins 14 released from the adsorption portion 24 land 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 planar position of the tip of the stack pin 37 can be adjusted to the correct position.

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

The central operation control unit 50 reaches the predetermined stacking height where the stacking height of the fin stack 15 is set in advance, and the stack pins 37 stand up on all the stack pin holders 38 of the table 36 at the standby position WP. If it is detected that the motor 32 is installed, 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. Here, the central operation control unit 50 (corresponding to the stack pin upright confirmation means) confirms that the operation control program of the fin stack take-out device 40 has executed a series of operations without causing an error, and thus the standby state is achieved. 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, with respect to the fin assembly 15 in the table 36 at the buffer position BP, the process of inserting the guide rod or the refrigerant pipe (neither is shown) into the through hole in which the stack pin 37 is not inserted is central. It is executed by the operation control unit 50. By thus inserting the guide rod or the refrigerant pipe into the fin stack 15 in which the stack pin 37 is inserted, the fin stack 15 when the table 36 rotates from the buffer position BP to the take-out position RP. It is possible to prevent the falling of.

The fin stacks 15 along the stack pins 37 are stacked at a predetermined stacking height on the stacker 31 sent from the buffer position BP to the take-out position RP. The central operation control unit 50 issues an instruction to the fin stack take-out device 40 arranged at the take-out position RP to take out the fin stack 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 stack takeout device 40 according to the present embodiment has an upper end holding portion 41 that holds the upper end portion of the stack pin 37 and a lower end holding portion 42 that holds the lower end portion of the stack pin 37. And a vertical movement mechanism 43 for vertically moving the upper end sandwiching portion 41 and the lower end sandwiching portion 42, and a horizontal moving mechanism 44 for horizontally moving the upper end sandwiching portion 41 and the lower end sandwiching portion 42. 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 periphery of the lower end portion of the stack pin 37. The operation of the fin stack extraction device 40 is controlled by the central operation control unit 50. A fin support 46 is attached to the upper side of the lower end holding portion 42.

In response to an instruction from the central operation control unit 50, the horizontal movement mechanism 44 is operated to bring the fin stack extraction device 40 close to the fin stack 15 (FIG. 5A). The central operation control unit 50 continues to open the upper end clamping unit 41 and the lower end clamping unit 42 to the position of the stack pin 37, closes the upper end clamping unit 41, and clamps only the upper end of the stack pin 37 (Fig. 5B). At this time, the lowermost bottom surface of the fin assembly 15 is held by the fin support 46.

Next, the central operation control unit 50 operates the vertical movement mechanism 43, raises only the upper end holding unit 41, and extracts only the stack pin 37 from the stack pin holder 38 (FIG. 5C). Next, the central operation control unit 50 closes the lower end clamping unit 42 to clamp the lower end portion of the stack pin 37, and activates the horizontal movement mechanism 44 to clamp the upper end portion and the lower end portion of the stack pin 37. 15 is moved in a direction away from the other fin assembly 15 (FIG. 5D).

As described above, the fin stack take-out device 40 holds the upper end and the lower end of the stack pin 37, and the fin stack 15 inserted in the stack pin 37 is integrated with the stack pin 37 in the table 36 ( Pull out from the stack pin holder 38).

The fin stack 15 that is pulled out from the table 36 together with the stack pin 37 is placed sideways on a conveyor 70 serving as a transport unit (FIG. 6A). The fin stack 15 in which the stack pins 37 are inserted is placed with 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 end sandwiching unit 42 from the sandwiched state, and moves the lower end sandwiching unit 42 in the direction of separating it from the fin stack 15 (upper side in FIG. 6B) (FIG. 6B).

Then, as shown in FIG. 6C, the central operation control unit 50 causes the stack pin 37 not to be pulled out from the upper end of the fin stack 15 (a state in which the stack pin 37 is guided in the through hole of the fin stack 15). ), The lower end of the stack pin 37 is held by 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 immediately 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, and the upper opening of the stack pin holder 38 is aligned. The opening size is formed larger than the lower opening size. As a result, the stack pin 37 can be correctly returned to its original position. In this way, when the stack pin 37 is re-installed on the stack pin holder 38, the stroke amount of the operating part such as an actuator (not shown) attached to the arm of the fin assembly take-out device 40 is changed to the operating part monitoring means or the operating part monitoring means. The central operation control unit 50 is monitoring.

In the present embodiment, the operating part monitoring means for monitoring the stroke amount of the operating part or the central operation control part 50 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 unit or the central operation control unit 50 does not normally end the series of operations in the fin stacking device 40 (removing the stack pin). It was possible to judge that the installation 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 at the standby position WP, and the stack height of the fin stack 15 at the stack position SP. When it is detected that the stack height has reached the predetermined stacking height, the motor 32 is driven to circulate each stacker 31 in the table circulating device 30 to the next position.

By repeatedly executing the above operation, the heat exchanger fins 14 supplied from the press device 20 can be made into a fin integrated body 15 and sequentially sent to the next process, which can be carried out fully automatically.

As described above, according to the fin assembly manufacturing apparatus 100 for the heat exchanger fins of the present embodiment, the table circulation device 30, the fin assembly extraction device 40, and the central operation control unit 50 cause the table 36 to be stacked. The heat exchanger fins 14 sent from the press device 20 are sequentially sent to the next position (process) as a fin integrated body 15 while being cyclically moved between the SP, the buffer position BP, the take-out position RP, and the standby position WP. The processing can be done automatically.

According to the configuration of the fin assembly manufacturing apparatus 100 for heat exchanger fins in the present embodiment, the fins for heat exchanger 14 are manufactured, the fin assembly 15 is formed by integrating the fins 14, and the formed fin assembly 15 is next A series of processes sent to the process can be automated. As a result, it is possible to manufacture the fin integrated body 15 of the fin 14 for the heat exchanger, which is extremely efficient, without causing a problem such as a handling error of the fin integrated body 15 due to manual intervention.

The feature is that 90 is provided.

The fin pressing mechanism 80 is for pressing the fin stack 15 accumulated on the upper surface of the table 36, and is located at both end positions of the fin stack 15 (both ends in the longitudinal direction when the fin stack 15 is viewed in plan). ) To hold down the fin assembly 15. The fin pressing mechanism 80 according to the present embodiment includes a fin pressing body 82 that presses the fin integrated body 15 by contacting both end positions of the fin integrated body 15 and a state in which the fin integrated body 15 is pressed by the fin pressing body 82 and is not pressed. The rotation motor 84 is provided as a switching control unit that controls switching between the dented state and the dented state. The operation of the rotation motor 84 is controlled by the central operation control unit 50. The rotation motor 84 rotates the fin pressing body 82 between a state in which the fin pressing body 82 is erected with respect to the upper surface of the table 36 and a state in which the fin pressing body 82 is horizontal with the upper surface of the table 36. Switching control is performed between the non-pressed state.

The operation of the fin holding mechanism 80 will be described. 9 to 11 are plan views of relevant parts for explaining the operation of the fin pressing mechanism 80 at the respective positions. Here, the operation at each position (position) of the fin pressing mechanism 80 arranged on the table 36 at the stack position SP in FIG. 9 will be described.

At the stack position SP, as shown in FIG. 9, in the fin holding mechanism 80, the fin holding body 82 is erected in a direction orthogonal to the upper surface of the table 36. By thus setting the fin pressing body 82 upright on the upper surface of the table 36, the fin pressing body 82 does not get in the way when the fin stacking body 15 is stacked.

When the height of the fin stacks 15 stacked on the upper surface of the table 36 at the stack position SP reaches a preset height, the central operation control unit 50 sets the table 36 at SP in FIG. Then, the rotation motor 84 is operated to rotate the fin pressing body 82 so as to be parallel (horizontal) to the upper surface of the table 36. In this way, by holding the fin stack 15 with the fin pressing bodies 82 so that the fin stack 15 is sandwiched from both ends of the fin stack 15, the fin stack 15 is prevented from collapsing when the table 36 is rotated. it can.

While the table 36 rotates and stands by at the buffer position BP, as shown in the table 36 in FIG. 10, the state in which both end positions of the fin stack 15 are held by the fin pressing body 82 is maintained. To be done. At the buffer position BP, the quality of the fin assembly 15 can be checked, the stack pin 37 can be pulled out, and the guide rod or the refrigerant pipe can be inserted. When the fin pressing body 82 rotates from the buffer position BP to the take-out position RP, both end positions of the fin stack 15 are held.

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 fin integrated body taking-out device 40 side, and the fin holding body 82. Is made to stand on the upper surface of the table 36. This is convenient because the fin pressing body 82 does not get in the way when the fin stack 15 is taken out by the fin stack take-out device 40 at the take-out position RP.

Then, when the removal process of all the fin stacks 15 at the removal position RP is completed, the central operation control unit 50 moves the table 36 at the removal position RP to the standby position WP. In the table 36 that has moved to the standby position WP, the central operation control unit 50 rotates so that all the fin retainers 82 (on both sides of the fin stack 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 at the standby position WP, it is assumed that all the stack pins 37 are erected and that all the fin pressing bodies 82 are erected on the upper surface of the table 36. It is also possible to set a moving condition to the position SP.

Next, the fin support mechanism 90 for stacking will be described. As shown in FIGS. 12 and 13, the fin supporting mechanism 90 at the time of stacking according to the present embodiment is attached to the suction portion 24 and is provided so as to be able to move toward and away from the fin stack 15 from above the fin stack 15. The integrated fin support mechanism 90 in this embodiment has a vertical movement mechanism 92, a rotation mechanism 94, and a fin support body 98.

The vertical movement mechanism 92 is for moving the fin support 98 in the height direction of the fin assembly 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 98 rotates in a horizontal plane and can move toward and away from the fin stack 15. The operations of the vertical movement mechanism 92 and the rotation mechanism 94 are controlled by the central operation control unit 50. Although an air cylinder is used as the vertical movement mechanism 92 and the rotation mechanism 94 here, another power mechanism in which a drive chain or a drive belt is wound around a sprocket or pulley rotated by a motor is used as the vertical movement mechanism 92 and the rotation mechanism 94. It can also be adopted.

The operation of the stacking fin support mechanism 90 will be described with reference to FIGS. 14 to 17. Here, for simplicity of description, the fin holding mechanism 80 is not shown in FIGS. 14 to 17. FIG. 14A shows a state immediately after the table 36 on which the stack pins 37 are erected has rotated from the standby position WP to the stack position SP. At this time, the stacking fin support mechanism 90 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 located on the side opposite to the side where the fin stack body 15 is formed.

Before starting the stacking process of the fin assembly 15 on the stack pin 37, the central operation control unit 50 performs a process of raising the lifting device 60 to lift the fin support 35 and the stack pin guide plate 39. Simultaneously with or immediately before or after this, the central operation control unit 50 extends the vertical movement mechanism 92 to separate the fin support 98 from the suction unit 24 (approaches the fin support 35) (FIG. 14B).

Next, the central operation control unit 50 operates the rotating mechanism 94 to rotate the fin support 98 connected to the rotating shaft 96 of the rotating mechanism 94 to the side where the fin stack 15 is formed (FIG. 15A). Next, the central operation control unit 50 integrates the heat exchanger fins 14 along the stack pins 37 to form the fin assembly 15. At this time, the central operation control unit 50 gradually lowers the position of the elevating device 60 as shown in FIG. 15B, and the heat exchanger fins 14 dropped from the adsorption unit 24 are always at the landing position where the fin support body 98 is on standby. I am trying to collect.

As shown in FIG. 16A, when the fin stack 15 reaches a predetermined stacking height, the lifting device 60 returns to the original standby position. Then, the central operation control unit 50 rotates the rotating mechanism 94 as shown in FIG. 16B to bring the fin support 98 away from the fin stack 15. Before separating the fin support 98 from the fin stack 15, it is preferable that the central operation control unit 50 actuate the fin pressing mechanism 80 so that the fin presser 82 presses the fin stack 15 from both sides. Next, as shown in FIG. 17, the central operation control unit 50 contracts the vertical movement mechanism 92 to move it closer to the suction unit 24 together with the fin support 98 (separate to a position above the fin stack 15) to stack the tables 36. Send from position SP to buffer position BP.

As described above, by additionally providing the configurations of the fin pressing mechanism 80 and the fin supporting mechanism 90 for stacking, the stacking state of the fin stack 15 is disturbed during stacking of the fin stack 15 and rotation of the table 36. Is advantageous 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 described 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 the stack position SP, the take-out position RP, and the standby position WP.

Further, in the present embodiment, the height dimension of the fin stack 15 stacked in the stacker 31 at the stack position SP is measured by the optical sensor provided in the lifting device 60, but this embodiment is described. It is not limited to. It is also possible to employ a mode in which a weight sensor that measures 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.

In the above embodiment, the table 36 of the stacker 31 is provided with the first spacers 33A and the second spacers 33B having different heights, but the spacers may have the same height. Further, it is also possible to adopt a mode 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 mode, the fin support 35 may be lifted by the lifting device 60 at the stack position SP. Further, at the take-out position RP, a lifter (not shown) for raising the fin support body 35 is provided in the fin stack take-out device 40, and the fin support body 35 is lifted from the upper surface of the table 36 by the lifter so that the lower end holding portion 42 enters. It is sufficient to form the gap S for this 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 of the fin assembly 15 where the stack pin 37 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 assembly 15 to separate the stack pin 37 and the fin assembly 15, the guide rod insertion machine GRM into the fin assembly 15 guides the guide rod. The GR may be attached together.

As for the process of pulling out the stack pin 37 and inserting the guide rod GR using the guide rod inserting machine GRM, known methods as shown in FIGS. 18A, 18B and 18C can be used. When pulling out the stack pin 37 from the fin stack 15 to separate the stack pin 37 from the fin stack 15, the guide rod insertion machine GRM to the fin stack 15 may also be used to mount the guide rod GR. For example, the buffer position BP can be omitted. This is advantageous in that the manufacturing cost of the fin assembly manufacturing apparatus 100 for heat exchanger fins 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.

In the second embodiment, the fin holding mechanism 80 includes a fin holding body 82, a rotation motor 84 for rotating the fin holding body 82, and the central operation control unit 50. It is not limited. The central operation control unit 50 employs a configuration in which the fin pressing body 82 is moved toward and away from both sides of the fin stack 15 by the switching control unit to switch between the pressed state and the non-pressed state of the fin stack 15. You can also

Further, in the second embodiment, the configuration having the fin holding mechanism 80 and the fin supporting mechanism 90 at the time of stacking is described, but only one of the fin holding mechanism 80 and the fin supporting mechanism at stack 90 is set to the first. It can also be added to the embodiment.

Furthermore, it is also possible to employ a configuration in which the configurations of the present embodiment and the configurations of the various modifications described above are appropriately combined.
