The flat tube 2 is inserted into the tube insertion groove 1a and is brought into close contact with and joined by the springback force of the fin collar 1d.

  Next, a heat exchanger manufacturing method and a heat exchanger manufacturing apparatus according to Embodiment 1 of the present invention will be specifically described with reference to FIGS. 2 is a diagram conceptually showing the configuration of the main part of the heat exchanger manufacturing apparatus according to Embodiment 1 of the present invention, and FIG. 3 is a trajectory diagram for explaining the operation of the movable positioning member shown in FIG. is there. In the figure, a heat exchanger manufacturing apparatus includes a punch device 3 for cutting a fin molded body 11 connected in a sheet shape or a hoop shape processed so that a large number of individual fins 1 are continuous, into individual fins 1; A fin insertion member 4 rotatably provided on a drum 7 as a rotating body, which will be described later, and individual fins cut by the punch device 3 so as to face the punch device 3 in conjunction with the punch device 3. 1 is provided, and positioning means 5 for holding the fin 1 on the fin insertion member 4 while positioning the fin 1 is provided.

  The fin molded body 11 is previously processed into a shape in which the individual fins 1 in FIG. 1 are connected in the vertical direction in the figure. The punch device 3 is configured using a punch 31 and a die 32, and a single piece of fin 1 is obtained by cutting a predetermined portion of the conveyed fin molded body 11. A holding member 6 (not shown) that holds the plurality of tubes 2 on the table 60 at predetermined intervals is installed at a predetermined position below the punch device 3. Between the punch device 3 and the table 60, continuously in the direction of arrow E by a motor (not shown) around an axis O parallel to the direction orthogonal to the extending direction of the tube 2 held by the holding member 6, or A drum 7 which is a rotating body that is driven to rotate intermittently is provided.

In the illustrated example, four fin insertion members 4 are provided at equiangular positions at positions A, B, C, and D so as to be rotatable around an axis P parallel to the axis O on the outer periphery of the drum 7. ing. And the fin insertion member 4 becomes a horizontal attitude | position in the example of the figure which receives and holds the fin 1 cut | disconnected in the position which opposes the punch apparatus 3 at the position. In the process of approaching the tube 2 held by the holding member 6, the fin insertion member driving means (not shown) is interlocked with the rotation of the drum 7 so that the held fin 1 is fitted to the outer peripheral surface of the tube 2. And is driven to rotate.

  The fin insertion member driving means (not shown) is configured to be driven by a motor (not shown), for example, or is configured to use a cam mechanism similar to that disclosed in Patent Document 1. be able to. The positioning means 5 which is one of the characteristic portions of the present invention is that the fin insertion member 4 is rotated when the fin insertion member 4 is rotated in the horizontal direction when receiving the fin 1 cut at the position A in FIG. A positioning projection 51 that projects from the outer peripheral surface of the drum 7 in the vicinity of the tip of the rotation locus and guides one end of the fin 1 (the left end in FIG. 2), and guides the other end of the fin 1 at that time. And a movable positioning member 52 attached to the drum 7 so as to be able to rotate around the inner end in the circumferential direction of the drum 7 as an axis Q, and the movable positioning member 52 is attached to the pipe 2 at a predetermined time. The cam 53 (shown in FIG. 3) is configured to rotate so as not to interfere with the fin 1 formed.

  In the figure, the positioning protrusion 51, the movable positioning member 52, and the cam 53 are all schematically shown, and the shape of the positioning protrusion 51 and the movable positioning member 52 is, for example, one of the opposed long sides of the fin 1. Further, a plate shape along most of the other shape, a plate partially along two or more spaced apart, or a cylindrical rod may be used. Assuming that the left-right direction of the fin 1 at the position A in FIG. 2 is the X-axis and the front-back direction of the drawing is the Y-axis, the positioning projection 51 and the movable positioning member 52 are positioned in the X-axis direction. For example, positioning can be performed by providing at least one protrusion (not shown) that enters the tube insertion groove 1a (shown in FIG. 1) on the surface of the positioning protrusion 51 that faces the movable positioning member 52.

  In order to reliably receive and accurately position the fin 1 that is lowered so as to fall from the punching device 3, the upper portion of the figure is widened with respect to the shape of the fin 1 in the positioning protrusion 51 or the movable positioning member 52. It is desirable to provide an inclined or smooth guide curved surface formed as described above. Moreover, it is preferable to form the surfaces of the positioning protrusion 51 and the movable positioning member 52 using a material that easily slides, for example, a resin material.

  Next, the operation of the first embodiment configured as described above will be described. When the fin molded body 11 is conveyed in the right direction in the drawing and supplied to a predetermined position of the punch device 3, the punch 31 descends in the direction of arrow F from above, and the punch 31 and the die 32 form the individual fins 1. Disconnect. After the cut fin 1 passes through the gap of the die 32, it is held in a state of being positioned by the positioning protrusion 51 and the movable positioning member 52 with respect to the fin insertion member 4 provided on the drum 7. In addition, the fin 1 is hold | maintained by the vacuum suction using a negative pressure with respect to the fin insertion member 4 (illustration omitted). The tube 2 is held on the table 60 by a holding device 6 (not shown) so that the major axis direction of the cross section is vertical, and is moved at a predetermined speed in the arrow G direction.

  As shown in FIGS. 3A to 3C, the movable positioning member 52 is moved from the position of the uppermost end shown in FIG. 2A to the position of the lowermost end C by the rotation of the drum 7. Rotated by the cam 53 interlocked with the drum 7 and rotated to a position where it does not interfere with the fin 1 already inserted into the tube 2. The operation of the movable positioning member 52 by the cam 53 constitutes a retraction process of the positioning means 5. The fin insertion member 4 is erected with the rotation of the drum 7 from A to B, and is held by the rotational force of the drum 7 when the drum 7 moves to the lowermost position of B to C. The fins 1 are vertically mounted on the outer peripheral surface of the tube 2 held on the table 60 so as to be arranged in parallel with each other at a predetermined interval. The tube 2 is moved continuously or intermittently in the direction of arrow G at a preset speed or pitch, and the interval between adjacent fins is determined by the setting.

  After the fin 1 is inserted into the tube 2, the movable positioning member 52 is rotated to the initial positioning position before moving to the position A at the uppermost end. Further, after the fin insertion member 4 is rotated counterclockwise from the position of FIG. 3C (the position of C in FIG. 2) and retracted to a position where it does not interfere with the fin 1 attached to the tube 2. A series of operations are driven by a cam (not shown) so as to be in a posture facing the punching device 3 at the position A after passing through the positions D and D. Then, by repeating the process of attaching one fin 1 to the tube 2 by rotating the drum 7, the heat exchanger shown in FIG. 1 having the desired number of fins 1 attached can be obtained. In addition, after the said fin insertion member 4 hold | maintains the fin 1, operation | movement itself fitted to the pipe | tube 2 is the same as that of the well-known technique described in the said patent document 1, etc., for example.

  As described above, according to the manufacturing method of the heat exchanger of the first embodiment, in the fin holding process, the individual fins 11 are individually separated from the fin moldings 11 that are processed so that a large number of individual fins 1 are formed in a sheet or hoop shape. The positioning includes the operation of receiving the individual fins 1 immediately after cutting from the punching device 3 and holding them with respect to the fin insertion member 4 while being positioned by the positioning means 5 in conjunction with the punching device 3 for obtaining the fins 1. Since one piece can be inserted into the flat tube 2 at a predetermined position without mistake, an effect is obtained that a heat exchanger free from fin deformation or pitch disturbance can be manufactured at a desired pitch.

  Further, according to the heat exchanger manufacturing apparatus of the first embodiment, the fins 1 obtained by cutting the fin-shaped body 11 in which the individual fins 1 are connected in a sheet or hoop shape one by one by the punching device 3 are movable. Since the fin insertion member 4 is held while being positioned by the positioning means 5 including the positioning member 52 and the positioning projection 51, the occurrence of defective products due to the deformation of the fin 1 or the disturbance of the fin pitch is suppressed, and the performance is stable. A high-performance heat exchanger can be manufactured in a short time and with high quality. Therefore, a high-efficiency heat exchanger with improved yield and improved heat exchange efficiency can be obtained, and energy can be saved. Here, since the positioning means 5 is constituted by the positioning protrusion 51, the movable positioning member 52, and the cam 53, the driving source of the movable positioning member 52 can be shared with the driving source of the drum 7.

Embodiment 2. FIG.

The upper and lower drive positioning members 55a and 55b are held so as to be held opposite to each other, and the vertical drive positioning members 55a and 55b are configured to move up and down following the movement of the push piece 56 provided on the punch 31. Has been.

  Protrusions (not shown) for positioning the fins 1 in the XY directions are formed on the opposing surfaces of the vertical drive positioning members 55a and 55b in the same manner as in the first embodiment, and are cut by the punch device 3. After receiving the fin 1, the fin 1 is positioned with respect to the fin insertion member 4 and then held by the fin insertion member 4. Other configurations are the same as those of the first embodiment.

  In the third embodiment configured as described above, as shown in FIG. 6A → FIG. 6B, as the punch 31 descends, the vertical drive positioning is performed by the push piece 56 attached to the punch 31. The members 55a and 55b are lowered, and the fin 1 is transferred to the fin insertion member 4 while being positioned just before the fin insertion member 4. Here, although the vertical drive positioning members 55a and 55b are divided into two parts, they may be connected at the front and rear portions in the transport direction (left and right direction in the figure) and driven by one push piece (not shown). ). In addition, after the fin 1 is cut, the vertical drive positioning members 55a and 55b are also raised as the punch 31 is raised.

  The fin insertion member 4 provided on the drum 7 holding the fin 1 rotates in the clockwise direction in the figure by rotating the drum 7 by a motor or the like (not shown). When the vertical drive positioning members 55a and 55b are moved to a position where the fin 1 can be positioned until just before the fin insertion member 4, the vertical movement positioning members 55a and 55b are raised and interfered with the fin insertion member 4 that rotates.

In the figure, the vertical drive positioning members 55a and 55b constituting the positioning means 5A are driven in the vertical direction by one push piece 56A that is moved up and down by a drive unit (not shown) independent of the punch 31. In the fourth embodiment, before the punch 31 is lowered and the fin 1 is cut, the vertical drive positioning members 55a and 55b are lowered by the push piece 56A, and the fin 1 is positioned until just before the fin insertion member 4. , And operates so as to be transferred to the fin insertion member 4 Although the vertical drive positioning members 55a and 55b are divided into two parts, they may be connected to each other at the front and rear parts in the transport direction to form one part. Other configurations are the same as those of the third embodiment.

  In the fourth embodiment configured as described above, the fin insertion member 4 provided on the drum 7 holding the fin 1 rotates and moves by rotating the drum 7 by a motor or the like (not shown). When the vertical drive positioning members 55a and 55b are moved to a position where the fins 1 can be positioned just before the fin insertion member 4, the vertical drive positioning members 55a and 55b rise because they interfere with the fin insertion member 4 that rotates. Then, after moving to a position where it does not interfere, the drum 7 is rotated, the fin insertion member 4 is moved to the lowermost end, and the fin 1 is inserted perpendicularly to the tubes 2 arranged on the table 60.

For example, the push piece 56A is positioned on the fin molded body 11 or on both sides. It may be. Moreover, what is necessary is just to select suitably the drive device (illustration omitted) of a movable positioning member according to the cutting | disconnection space | interval of the fin molded object 11, such as an air cylinder, a motor, a solenoid actuator, for example.

  According to the fourth embodiment configured as described above, since the vertical drive of the punch 31 and the vertical drive positioning members 55a and 55b shown in the third embodiment are not dependent, the fin 1 is held by the fin insertion member 4. Then, the vertical drive positioning members 55a and 55b can be raised at an arbitrary timing, which leads to a reduction in production time and equipment costs. In addition, since the vertical drive positioning members 55a and 55b have their own drive units, it is easy to adjust the equipment.

  It should be noted that within the scope of the present invention, a part or all of each embodiment can be freely combined, or each embodiment can be appropriately modified or omitted. For example, the drum 7 is not necessarily limited to a cylindrical one, and for example, a plurality of frame materials can be combined to form a rotating body. The movable positioning member 52 or the vertical drive positioning members 55a and 55b may be retracted in the center direction of the drum 7 (the direction of the axis O). Needless to say, various modifications and changes can be made.
