Description

  The present invention relates to a winding device and a winding method for an edgewise coil used as various coil members for in-vehicle devices and electronic devices.

  An edgewise coil in which rectangular wires are wound vertically has the advantage of a square cross section and a high space factor, and is useful for reducing the size and efficiency of the device. A winding device for winding an edgewise coil in a bobbinless manner is described in, for example, Patent Document 1, and a wire rod is rolled into a rectangular shape at a rolling part and the wire rod feed direction is regulated by passing it through a lead-out hole of a wire rod guide. However, it is made to curve in the shape of a coil on the inclined surface of the coil forming portion arranged to face the lead-out hole of the wire. A block body provided with an inclined surface or an inclined groove or a roller having a circumferential groove is used for the coil forming portion.

  At this time, the coil pitch forming portion disposed above the wire rod guide deflects the feed angle of the wire rod to be bent to form a predetermined pitch. Further, the supply of the wire is monitored by the control unit, and when a wire length corresponding to a predetermined number of turns is supplied, the wire is cut with a cutter. Thus, the manufacture of a circular coil is facilitated by carrying out a series of steps of using a wire rod as a coil having a predetermined shape with one apparatus.

  Patent Document 2 discloses an apparatus for forming an edgewise coil having a shape including a bent portion and a non-bent portion. This apparatus includes a feeding mechanism that feeds a wire corresponding to a non-bending portion, a bending jig that bends the wire while rotating the winding, and a side support that supports the side of the non-bending portion of the winding. A synchronization mechanism is provided so that the side support portion rotates synchronously with the winding. Since the side support portion supports the non-bending portion of the winding, deformation of the winding due to inertia is prevented and workability is improved even when the winding speed of the winding is high.

  However, in the apparatus described in Patent Document 1, the coil track is free after the wire rod fed out from the lead-out hole of the wire rod guide is brought into contact with the inclined surface of the coil forming portion, and the coil shape is free. It does not have means to arrange and hold. Further, as the number of coil turns increases, the inertial force also increases, so that the position after winding varies according to the number of turns, and the winding diameter varies, resulting in poor alignment. Further, the coil forming portion has a simple structure that is shaped and bent following the inclined surface of the block body or the inclined surface of the roller groove, and is not suitable for non-circular coil shapes other than circular coils.

  On the other hand, the apparatus described in Patent Document 2 is provided with a side support portion in order to avoid the coil being free. Therefore, when the bending portion (corner portion) is formed and bent, the winding formed by inertia force is deformed, and when the non-bending portion is fed by the feeding mechanism, the occurrence of vibration in the non-bending portion is suppressed. be able to.

  However, the apparatus of Patent Document 2 requires a large number of side surface support portions in order to always support the coil side surface during forming bending and feeding. Specifically, the outer side of the coil is supported by the rotation support block for the long side and the rotation support block for the short side to suppress vibration during rotation, while the long side bending stopper block and the short side bending stopper are provided. It is provided at a stop position after bending, and further rotation of the coil is restricted at the stop position after bending. Furthermore, a mechanism is provided that allows the long-side bending stopper block and the short-side bending stopper to advance and retreat out of the rotation area so as not to interfere with the flow line of the coil, and the device configuration tends to be complicated.

  Therefore, the present invention can form a non-circular edgewise coil into a desired shape without deteriorating the alignment even when the number of turns increases, and does not require complicated equipment or procedures. An object of the present invention is to provide a winding device and a winding method capable of manufacturing a simple coil relatively easily.

The winding mechanism 1 shown in FIG. 1 bends the supplied wire W into a corresponding shape at a portion corresponding to the semicircular portion C1 of the edgewise coil C, and sends the portion corresponding to the straight portion C2 without being processed. By repeating this, a predetermined coil shape is obtained. The details will be described next.

  1A and 1B, a winding mechanism 1 includes a main shaft 2 that can rotate and move in an axial direction (up and down movement in the figure), and a core metal 3 that is disposed around the lower end portion of the main shaft 2. And a clamp member 4 that is positioned below the core bar 3 and is provided integrally with the main shaft 2 to form a clamp mechanism for the wire rod W, and a revolving roller 5 for winding the wire rod disposed on the outer periphery of the core bar 3. have. The main shaft 2 is connected to a drive motor 21 and is driven up and down integrally with the clamp member 4 or is driven to rotate around the shaft. The revolution roller 5 is driven by the drive motor 51 via the transmission gear 52 and can revolve around the main shaft 2.

  The core metal 3 is an annular body having a through hole 31 through which the main shaft 2 is inserted at the center, and is screwed to the lower end portion of the cylindrical member 33 fixed to the lower surface of the fixed base B. A substantially disc-shaped clamp member 4, which will be described later in detail, is integrally provided at the tip of the main shaft 2 that protrudes downward from the through hole 31 of the core metal 3, and moves up and down together with the main shaft 2 to clamp the wire. Alternatively, the wire rod is fed by rotating 90 degrees. The core metal 3 has a lower surface outer peripheral portion projecting downward in a stepped manner to form an annular convex portion 32, while the clamp member 4 has an upper surface outer peripheral portion recessed in a stepped manner and is engaged with the annular convex portion 32. An annular recess 41 is formed. The wire W is supplied between the cored bar 3 and the clamp member 4, and is sandwiched between the engaging portions of the outer peripheral annular protrusion 32 and the annular recess 41 at the illustrated clamp position.

  The revolution roller (winding roller) 5 has a substantially trapezoidal cross-sectional shape with its lower end projecting outward in a flange shape, and the lower side surface projecting to the inner periphery is held between the clamp member 4 and the cored bar 3. It is in contact with the wire W. The revolving roller 5 is fixed to the lower surface of the cylindrical body 53 that is rotatably supported on the outer periphery of the cylindrical member 33, and is driven to rotate 180 degrees via the transmission gear 52. FIG. 3A is a top view of the winding mechanism 1, and the wire W is supplied between the cored bar 3 and the revolving roller 5, and the revolving roller 5 is connected to the cored bar 3 as the cylindrical body 53 rotates. The state of revolving around the main shaft 2 along the outer periphery is shown.

  FIG. 3B is another side view of the winding mechanism 1. The wire supplied from the feeding mechanism 11 of FIG. 2 is wound around the cored bar 3 by driving the revolving roller 5, and the wound coil is A mode that the lower coil receiving part 12 hold | maintains is shown typically. The coil receiver 12 includes a coil tray 12a and a spring member 12b that urges the coil tray 12a upward. The coil receiver 12 is lowered by its own weight as the coil is wound. The coil tray 12a is provided so as to be movable in the horizontal direction by the driving device 12c, and when the wire W is fed, the coil wound together with the coil tray 12a is slid sideways. Thereby, the alignment state of the edgewise coil C after shaping | molding can be maintained.

Next, details of wire rod clamping by the clamp member 4 and winding by the revolving roller 5 will be described. FIG. 4A is a diagram schematically showing the positions and operations of the clamp member 4 and the revolving roller 5 with respect to the cored bar 3. The annular convex portion 32 of the core metal 3 is engaged with the annular concave portion 41 of the clamp member 4 to form a U-shaped groove 6 that opens to the outer periphery. The wire W is held. As shown in FIG. 4B, the clamp member 4 is connected to the lower end of the main shaft 2 and has a substantially circular plate shape that expands radially outward with a step, and includes a thick circular central portion 42 and a thin outer peripheral edge portion. And an annular recess 41 is formed outside the circular central portion 42. The groove bottom of the U-shaped groove 6, that is, the side surface of the circular central portion 42 of the clamp member 4 is formed with a predetermined curvature corresponding to the winding shape of the edgewise coil C.

  In the clamp member 4, the upper surface of the thin outer peripheral edge portion is a pressing portion 4 a for the wire W, and a part of the outer periphery is cut out along the circular central portion 42 to form a non-pressing portion 4 b. The non-pressing portion 4b is formed on the side opposite to the side where the revolving roller 5 revolves and winds the wire W. In addition, the angle α formed by the outer circumferential arc-shaped portion serving as the pressing portion 4a is set to be larger than 180 degrees at which the revolving roller 5 revolves so that the winding of the wire W is not hindered.

  In FIG. 4A, the clamp member 4 is lifted together with the main shaft 2 and is pressed against the metal core 3, and the clamp member 4 is moved downward along with the main shaft 2 and is unclamped at two positions allowing the wire W to be fed. Controlled. When the clamp member 4 is at the unclamping position, the wire W is fed at a predetermined feed amount in the direction of the arrow in the figure as shown in FIG. Thereafter, when the revolving roller 5 is revolved 180 degrees along the core metal 3 with the clamp member 4 as a clamping position, the sent wire W is bent into a semicircular shape by the revolving roller 5, and the semicircular portion of the edgewise coil C C1 is formed. This winding image is shown in FIG.

  Here, as shown in FIG. 5A, the outer diameter of the clamp member 4 is larger than the inner diameter of the semicircular portion C1 of the edgewise coil C. Therefore, as shown in FIG. 5C, when the wire W is wound spirally, the clamp member 4 and the R-shaped winding portion of the edgewise coil C interfere with each other when the wire W is fed. Become. Therefore, in the present invention, a part of the outer peripheral edge portion of the clamp member 4 is cut out (dotted line portion in the figure) to form a non-pressing portion 4b that does not interfere with the coil. Since the clamp member 4 can rotate 90 degrees together with the main shaft 2, the non-pressing portion 4 b is arranged on the side opposite to the orbit of the revolving roller at the time of winding shown in FIG. Thereafter, when the wire W is fed, the clamp member 4 is rotated 90 degrees to a position where the non-pressing portion 4b is parallel to the feed direction of the wire W as shown in FIG. Oppose to C2. By carrying out the feeding of the wire W in this state, it is possible to remove the coil that has been wound up and to subsequently wind it up.

  The winding method of the edgewise coil C by the winding device having the above configuration will be described with reference to the schematic diagrams of FIGS. Here, the description will focus on the driving of the clamp member 4 and the revolution roller 5, which are the main parts of the winding mechanism 1, and the feeding of the wire W by the feeding mechanism 11. The figure is a downward view of the winding mechanism 1 of FIG. 1, and the clamp member 4 and the revolving roller 5 illustrate the lower end surface. First, in the step 1) of FIG. 6, the wire W supplied from the feed mechanism 11 of FIG. 2 is set in the winding mechanism 1 (wire set). At this time, the linear wire W is in contact with the revolving roller 5 at the original position, and the U-shaped groove 6 formed in the outer peripheral portion of the cored bar 3 and the clamp member 4 at the opposite position (see FIG. 4A). Arranged to pass through.

  Next, in the step 2), the wire W for a predetermined length is sent out (wire feed 1). Specifically, the wire W corresponding to the length of the semicircular portion C1 and the straight portion C2 of the edgewise coil C is advanced to the predetermined position with respect to the set position of 1) in the direction of the arrow in the figure (feed amount: L). Supply. When supplying the wire W, the clamp member 4 is lowered together with the main shaft 2 by the drive motor 21 to be in an unclamped state. After supplying the wire W, the clamp member 4 is lifted together with the main shaft 2 by the drive motor 21, and the wire W is sandwiched between the core metal 3 and the clamp member 4 to be in a clamped state.

  Thereafter, in step 3), the revolving roller 5 is driven by the drive motor 51 and revolved 180 degrees along the outer periphery of the cored bar 3 to wind up the wire W (180 ° bending 1). At this time, the wire W bent by the revolving roller 5 is held in the U-shaped groove 6 between the pressing portion 4a of the outer peripheral edge portion of the clamp member 4 and the annular convex portion 32 of the opposite core metal 3, and has a groove shape. Wrapped in a semi-circle along. After the winding, in step 4), the clamp member 4 is lowered to perform unclamping, and the revolving roller 5 is revolved 180 degrees to the original position (roller return 1). As a result, one semicircular portion C1 and straight portion C2 of the edgewise coil C are formed.

  In the steps 5) to 8) of FIG. 7, the other semicircular portion C1 and straight portion C2 of the edgewise coil C are formed. First, in the step 5), the wire W for a predetermined length is sent again with the clamp member 4 in the unclamping position (wire feed 2). Specifically, the wire W is advanced to the predetermined position with respect to the set position of 1) in the direction of the arrow in the figure (feed amount: 2L), and corresponds to the length of the semicircular portion C1 and the straight portion C2 of the edgewise coil C. Is supplied again. After supplying the wire W, the clamp member 4 is brought into a clamped state.

  In the step 6), the revolving roller 5 is driven and revolved 180 degrees along the outer periphery of the cored bar 3 to wind the wire W (180 ° bending 2). As a result, another pair of other circular portions C1 is wound up at a position facing the circular portion C1 formed in the step 3) in FIG. 6, and one turn (first step) of the oval edgewise coil C is taken up. ) Is formed. Next, in order to form the second and subsequent stages, in step 7), the clamp member 4 is brought into an unclamped state, and the revolving roller 5 is revolved 180 degrees to the original position (roller return 2).

  Thereafter, in the step 8), the clamp member 4 is rotated 90 degrees using the drive motor 51 (clamp rotation 1). This is because, after the step 7), the edgewise coil C has the first 1/2 turn and the next 1/2 turn of the first stage positioned above and below the clamp member 4. The wire rod W is rotated in advance so as not to interfere with the clamp member 4 when the wire W is fed. At this time, the non-pressing portion 4b of the clamp member 4 is rotated to a position parallel to the feeding direction of the wire W, and here, the straight line of the edgewise coil C positioned above the clamp member 4 (lower side in the figure). It is made to oppose part C2.

  In this state, the second and subsequent stages of the edgewise coil C are formed by the steps 9) to 12 in FIG. In the step 9), first, the wire W for a predetermined length is sent again with the clamp member 4 in the unclamping position (wire feed 3). Specifically, the wire W corresponding to the length of the semicircular portion C1 and the straight portion C2 of the edgewise coil C is advanced in the direction of the arrow in the figure to the predetermined position with respect to the set position of 1) (feed amount: 3L). Is supplied again. After supplying the wire W, the clamp member 4 is brought into a clamped state.

  As described above, when the turn is switched, the edgewise coil C wound in a predetermined shape with the supply of the wire is shifted in the horizontal direction and detached from the U-shaped groove 6 formed by the core metal 3 and the clamp member 4. become. The detached edgewise coil C is received while the coil receiving tray 12a of the coil receiving portion 12 shown in FIG. 3 follows the horizontal direction. As the number of turns increases, the coil tray 12a gradually descends and receives the wound edgewise coil C, so that the alignment of the formed coil can be maintained and high quality can be maintained.

  Next, in the step 10), the clamp member 4 is rotated 90 degrees using the drive motor 51 to return to the original position (clamp rotation 2). This is because after the wire W is fed, the pressing portion 4a of the clamp member 4 is set to a position along the track of the revolving roller 5 and is wound again. In the step 11), the revolving roller 5 is driven and revolved 180 degrees along the outer periphery of the cored bar 3 to wind the wire W (180 ° bending 3). In step 12), the revolving roller 5 is revolved 180 degrees to the original position (roller return 3).

  By repeating this process, the second and subsequent stages of the edgewise coil C are similarly formed. Therefore, by repeatedly performing the supply and winding operation of the wire W so as to obtain the desired number of turns, the non-circular edgewise coil C having a desired number of stages can be wound with good alignment as shown in FIG. it can. In particular, since the clamp member 4 is provided so as to be rotatable and vertically movable, the wire W is sandwiched in the U-shaped groove 6 formed by the core metal 3 and the clamp member 4, and the wire W is rotated by the rotation of the revolving roller 5. The semicircular portion C1 of the edgewise coil C can be formed into a desired shape with good reproducibility by being wound around the bottom of the groove 6, and the wire W can be fed without interference with the wound edgewise coil C.

  Further, as shown in FIG. 3, the wound edgewise coil C is held by the coil receiving portion 12 that descends by its own weight, and can be moved horizontally together with the coil receiving portion 12 when feeding the wire W. High quality products can be manufactured efficiently.

  In the above embodiment, the edgewise coil C is an oval having a semicircular portion C1 and a straight portion C2. However, the edgewise coil C is not limited to a semicircular shape, but may be an ellipse or any other noncircular shape having a curved portion and a straight portion. The present invention can be applied and the same effect can be obtained.

  As described above, according to the winding device and winding method of the present invention, a non-circular edgewise coil can be formed without variation in winding diameter, and a coil having excellent alignment even when the number of turns increases is manufactured. Can do. Such an edgewise coil can be suitably used as a coil member for an electronic device, a control device, a power supply device, or a driving device used for various applications such as in-vehicle use or home appliances.
