The driving pulley 38 is connected to a motor, which is a driving source (not shown), by a belt, and can be rotated by driving the motor.

Accordingly, by rotating the drive pulley 38, the forming jig rotating means 30 and the forming jig 20 are rotated about the winding jig 11. As a result, since the forming jig 20 rotates around the winding jig 11 while the winding jig 11 and the forming jig 20 hold the flat wire W, the flat wire W can be bent.
As shown by a solid line in FIG. 2, when the forming jig 20 is positioned in a direction perpendicular to the feeding direction of the flat wire W with respect to the winding jig 11, this position is the forming jig 20. This is the initial position S at which bending is started.

As shown in FIGS. 4 and 5, when the deformed flange 13 is located at the uppermost position, the lower surface of the flat wire pressing portion 13 </ b> A of the deformed flange 13 is set to be higher than the lower surface of the flange 21 </ b> B by a predetermined dimension. Has been.
That is, a maximum gap S1 is formed between the upper surface of the flat wire W and the lower surface of the flat wire pressing portion 13A of the deformed flange 13 in order to easily feed the wire, that is, the flat wire W.
When the flat wire W is sent out, the forming jig 20 is retracted from the deformed flange 13 of the winding jig 11 as indicated by an arrow N1 in FIG.

  Further, as shown in FIG. 6, when the flat wire W is bent, when the flat wire W sent along the feed direction (in the direction orthogonal to the plane of FIG. 6) is pushed down substantially horizontally by the deformed flange 13, the deformed flange 13 rectangular wire pressing portions 13A are located at the lowest position, and at this time, the lower surface of the flange 21B and the upper surface of the rectangular wire W are in contact with each other. Further, the width dimension of the recessed groove 21D between the flanges 21B and 21C is formed to be larger than the thickness dimension of the flat wire W by a predetermined dimension as described above.

On the other hand, the gap between the lower surface of the flat wire pressing portion 13A and the upper surface of the flat wire W in the deformed flange 13 is smaller than the gap S1 in order to prevent film peeling due to the wire bulge of the bent portion R on the winding core side. It is a gap S2.
Then, when the flat wire W is bent, the forming jig 20 is advanced toward the deformed flange 13 side of the winding jig 11 as indicated by an arrow N2 in FIG.

  With respect to the flat wire W sent in the delivery direction, the deformed flange 13 is pushed down to make the flat wire W substantially horizontal by the flat wire pressing portion 13A of the deformed flange 13, and the flat wire W is bent at a predetermined angle by the forming jig 20.

Increase by pitch (thickness). At this time, the first laminated coil WC1 is placed on the upper surface of the first support member 51. Since the first laminated coil WC1 and the second laminated coil WC2 are connected by the intermediate connecting portion R as described above, the first laminated coil WC1 is also raised by the above one pitch.
As a result, since the first laminated coil WC1 is separated from the upper surface of the first support member 51 in the state as it is, by driving the support body driving means 60 for the first support member 51 and the second support member 52, The first support member 51 and the second support member 52 are raised by the one pitch, and the state where the first laminated coil WC1 is held on the upper surface of the first support member 51 is maintained.

When the second laminated coil WC2 is rolled up to the set height in step 6 and completed, the support driving means 60 for the second support member 52 is driven as shown in FIG. The second support member 52 is lowered to the initial height position to create a standby state for the completed second laminated coil WC2.
The standby state at this time is a state where the second laminated coil WC2 is not placed on the second support member 52 in FIG.

After step 7, in step 8 as an eighth step, the first laminated coil WC1 is held on the upper surface of the first support member 51 and the second laminated coil WC2 is held on the upper surface of the second support member 52 as shown in FIG.

After the transfer, the second laminated coil WC2 can be manufactured by repeating the same flat wire W feeding operation and bending work operation. During the formation of the second laminated coil WC2, the first laminated coil WC1 The upper surface of the support body 50 including the first support member 51 and the second support member 52 is rotationally slid or stopped and held. Thereby, the connection coil WC in which two rectangular tube-shaped laminated coils are continuous can be easily manufactured.

(2) Since the dividing surface D of the first support member 51 and the second support member 52 is formed at a position away from one end in the width direction of the flat wire W, when the flat wire W is sent out along the sending direction K The extension portions of the connecting portions of the rectangular wires W on the lower surfaces of the formed first laminated coil WC1 and second laminated coil WC2 are all placed on the first support member 51 or the second support member 52, thereby stabilizing. The posture can be maintained.

(3) In order for the 1st support member 51 and the 2nd support member 52 to go up and down, both the support members 51 and 52 need to be arrange | positioned above the flat wire W, On the other hand, the 1st support member 51 and The second support member 52 must support the formed first laminated coil WC1 or the second laminated coil WC2, but the upper surface of the second support member 52 is formed on the upstream side in the conveyance direction K of the flat wire W. And a flat first upper surface 52A located above the rectangular wire W, a flat second upper surface 52B on which the first laminated coil WC1 or the second laminated coil WC2 is placed, and the first upper surface 52A and the second upper surface. It has a shape having an inclined upper surface 52C connecting the 52B. Accordingly, the formed first laminated coil WC1 or second laminated coil WC2 can be placed on the second upper surface 52B in a stable posture, and the first supported coil WC1 and WC2 are supported in a state in which the first laminated coil WC1 and the second laminated coil WC2 are supported. The member 51 and the second support member 52 can be moved up and down.

(4) The bending area 50A is formed in a circular shape centered on the winding jig 11, and the size of the circular shape is determined when the first laminated coil WC1 and the second laminated coil WC2 are formed. The first laminated coil WC1 and the second laminated coil WC2 are sized so as not to interfere with the first support member 51 and the second support member 52. Accordingly, when the first laminated coil WC1 or the second laminated coil WC2 is formed, the bending work after the sending work of the flat wire W becomes the rotational motion of the flat wire W, but the circular bending work region 50A. It is possible to perform bending without interfering anywhere, and the processing can be performed smoothly.

(5) The support driving means 60 that supports the first support member 51 and the second support member 52 and is capable of moving up and down independently connects the lift vertical shafts 61 and the lift vertical shafts 61. Since the first support member 51 and the second support member 52 are supported by a plurality of lift vertical shafts 61, the connection member 65 and a vertical drive motor 67 that drives the connection member 65 are provided. The posture can be maintained.

(6) The vertical movement of the connecting member 65, that is, the raising and lowering of the first support member 51 and the second support member 52, drives the pinion fixed to the connecting member 65 by the vertical drive motor 67, and engages the rack with this pinion. Since they are combined, mechanical driving is performed, and the first support member 51 and the second support member 52 can be moved up and down reliably.

(7) When forming the second laminated coil WC2 in the bending region 50A, the first support member 51 and the second support member 52 are raised for each turn of the second laminated coil WC2 by the control of the vertical drive motor 67. It has a configuration. The second laminated coil WC2 and the first laminated coil WC1 are continuous at the connecting portion R. When the second laminated coil WC2 is wound once, the first laminated coil WC1 is also raised by one turn. Therefore, when the first support member 51 and the second support member 52 are left as they are, the laminated coil WC1 is in a lifted state, but the first support member 51 and the second support member 52 are lifted for each turn. The one laminated coil WC1 can be kept in a state of being always in contact with the first support member 51, the second support member 52, or the first and second support members 51, 52, and as a result, stable support is possible.

  For example, in the above-described embodiment, the bending region 50A for forming the first laminated coil WC1 and the second laminated coil WC2 has a circular shape, but the present invention is not limited to this, and may have a rectangular shape. In short, it is only necessary to bend the first laminated coil WC1 and the like without any trouble.

  Moreover, in the said embodiment, the division surface D of the 1st support member 51 and the 2nd support member 52 is the part which the end surface of the 1st support member 51 left | separated from the width direction one end surface of the flat wire W sent out, ie, 1st. The two support members 52 are formed so as to protrude to the first support member 51 side, but the opposite may be possible. That is, the first support member 51 is formed so as to protrude from the one end surface in the width direction of the flat wire W toward the second support member 52, and the flat wire W is sent out below the first support member 51. Good.

  Further, in the above-described embodiment, the support driving means 60 for moving the first support member 51 or the second support member 52 up and down connects the connecting member 65 connecting the two coil receiving guide shafts 62 to the vertical drive rack 66 and the pinion. However, the present invention is not limited to this. Instead of the configuration by the engagement between the vertical drive rack 66 and the pinion, the configuration may be such that the connecting member 65 is moved up and down by a cylinder (not shown).

Moreover, in the said embodiment, among the 1st support member 51 and the 2nd support member 52, the upper surface of the 2nd support member 52 is made into the 1st upper surface 52A, the 2nd upper surface 52B, and the inclined upper surface 52C, and the 2nd support member 52. However, the upper surface of the first support member 51 may be an upper surface having a similar shape.
In this way, when the second laminated coil WC2 is formed, the completed first laminated coil WC1 rotates the upper surfaces of the first support member 51 and the second support member 52 for each turn of the second laminated coil WC2. However, since the second upper surface of the first support member 51 and the second upper surface 52B of the second support member 52 have the same height, the transfer from the first support member 51 to the second support member 52 is performed. Is performed smoothly, whereby the posture of the completed first laminated coil WC1 can be held in a stable state.

  In the present invention, a rectangular wire with a rectangular cross-section is sequentially bent with one end face in the width direction on the inside and the other end face on the outside, and a first laminated coil laminated at a predetermined height is manufactured.
