  The problem to be solved is that in the conventional edgewise coil winding device, the tip of the flat wire 10 is tentatively fixed beforehand by tangling the tip of the flat wire 10 to the set screw provided on the weight 9 side in advance. After winding, the rectangular wire 10 behind the coil is manually cut, and the core shafts 71 and 72 are pulled upward together with the weight 9, and the coil wound with the heating jig is heated and melted. After the attachment, the wound coil 17 is taken out from the core shafts 71 and 72, and manpower is required for manufacturing the edgewise coil, and the workability is deteriorated.

The present invention includes a vertically disposed rotating shaft that rotates using a motor as a drive source, and a core shaft having an elliptical cross section that is loosely fitted from above into a hole drilled in the axial direction of the rotating shaft; It consists of a weight attached to the upper part of the core shaft, and a flat wire sent from the lateral direction so that the wire surface is along the upper end surface of the rotary shaft is the upper end surface of the rotary shaft and the upper part of the core shaft. An edgewise coil winding apparatus that winds a rectangular wire around the core shaft while pushing the core shaft upward together with the weight by rotating the rotary shaft. The flat wire on the rotary plate provided coaxially with the rotary shaft is sent at the tip of the flat wire sent from the lateral direction so that the wire surface is along the upper end surface of the rotary shaft arranged vertically. Means for clamping to a first clamper pivotally attached to one end of the side, and Means for peeling off the coating on the surface of the flat wire in the front portion that is being ramped, and rotating the rotating plate by a predetermined angle so that the flat wire is formed in the upper end surface of the rotating shaft and the hole drilled in the axial direction of the rotating shaft from above Means for clamping to a second clamper provided on the core shaft side by sandwiching it between the loosely mounted core shaft and pressing it against the core shaft and pressing it against the core shaft And means for rotating the rotating shaft to push the core shaft upward along with the weight while winding the flat wire around the core shaft, and peeling the coating on the surface of the rectangular wire at the rear part of the wound coil. Means for pressing the electrodes against the peeled portion at the back and the peeled portion at the front of the wound coil to fuse the coil by energization, and a rectangular wire behind the wound coil. Is clamped to the first clamper and It means for cutting the flat wire of the other party of the ramp portion, so that by pulling up on the winding core shaft upwardly provided with means for taking out the wound coil.

  According to the present invention, the manufacture of the edgewise coil can be performed with full automation.

  FIG. 1 shows a basic configuration example of a winding device in which an edgewise coil having an elliptical cross section is wound.

  Here, the winding device has a predetermined tensile force applied to the winding device main body 20 installed on the gantry 1 and the rectangular wire 10 attached to the bobbin 22 supported so as to be able to rotate on the support member 21 on the fixed side. And a wire material supply unit 23 that supplies the winding device body 20 to the winding device main body 20 and a tension fluctuation mitigation mechanism unit 24 that relieves fluctuations in winding tension when winding the rectangular wire in the winding device main body 20.

  As shown in FIG. 2, the winding device main body 20 is screwed to a rotating shaft 3 that is rotatably disposed in a vertical direction by a bearing 2 screwed to the upper portion of the gantry 1 and a lower portion of the gantry 1. A pulse motor 4, a coupling 5 that connects the rotary shaft 3 and the rotary shaft 41 of the pulse motor 4, and a hole 6 having a flat circular cross section that is formed in the axial direction of the rotary shaft 3, respectively, from above. It is composed of two core shafts 71 and 72 that are loosely inserted with the spacer 18 in between (see FIG. 3), and a weight 9 mounted on the upper part of the pair of core shafts 71 and 72.

  Further, the upper end surface of the rotation shaft is used as a coil receiving surface, and a receiving table 11 is disposed so that the receiving surface of the flat wire 10 is positioned at a position parallel to the surface. A weight 12 is provided on the receiving table 11 with a guide 13. The tension mechanism 14 attached so as to be movable up and down is provided in the supply system of the flat wire 10, and the flat wire 10 sent from a wire supply unit (not shown) between the receiving base 11 and the weight 12 has a thickness. It is designed to generate tension during winding by sandwiching in the direction.

  The cradle 11 in the tension mechanism unit 14 is rotatably mounted by a bearing 15 screwed onto the gantry 1 so that the tensioned rectangular wire 10 can be smoothly fed out.

  As the tension fluctuation mitigating mechanism 24, a moving pulley 27 is provided by the wire 10 that is provided between the wire supply unit 23 and the winding device main body 20 and is fed from the bobbin 22 through a pair of rollers 25 and 26 provided on the fixed side. It has a structure to suspend. Then, one end of the chain 29 is attached to the mounting member 28 of the movable pulley 27, the other end of the chain 29 is freely placed on the floor surface 30, and the chain 29 is pulled by a tensile force acting on the flat wire 10 when the coil is wound. At the same time, the moving pulley 27 rises, and the rectangular wire 10 is sent out when the torque due to the weight of the chain 29 and the moving pulley 27 reaches the torque for rotating the bobbin 22.

  In the winding apparatus configured as described above, the starting end of the flat wire 10 that is sent in the lateral direction along the coil receiving surface (upper end face) of the rotating shaft 3 is placed on the weight 9. When the rotating shaft 3 is rotated at a constant speed after being sandwiched between the coil receiving surface of the rotating shaft 3 and the weight 9 by its own weight, the core shafts 71 and 72 together with the weight 9 are rotated according to the rotation. The rectangular wire 10 is wound around the pair of core shafts 71 and 72 in a state in which a constant winding tension is applied by the tension mechanism unit 14 while pushing up.

  In this case, as shown in FIG. 5, when winding the edgewise coil 17 having an elliptical cross section, the winding speed of the rectangular wire 10 changes due to the difference between the major axis and the minor axis, and the tension varies. However, according to the fluctuation, the moving pulley 27 in the tension fluctuation reducing mechanism unit 24 is appropriately raised and lowered together with the chain 29 to absorb and relax the fluctuation of the tension, and depends on the weight of the chain 29 and the moving pulley 27. The torque is always held so as to be a torque for rotating the bobbin 22.

  In this way, even if the rotational speed of the rotary shaft 3 is increased, the length of the chain 29 suspended by the upper and lower movements of the movable pulley 27 suspended on the flat wire 10 changes, and the flat angle depends on the weight at that time. The fluctuation of the tension in which the wire 10 is pulled or loosened is absorbed and relaxed with good responsiveness, and the edgewise coil 17 having an elliptical cross section can be wound with a constant winding tension.

  Further, the structure of the winding device main body 20 is such that the supplied flat wire 10 is sandwiched between the coil receiving surface and the flat wire previously wound around the core shafts 71 and 72 to rotate the rotating shaft 3. Accordingly, while pushing up the core shafts 71 and 72 together with the weight 9, the coil is pressed with its own weight and wound with good adhesion. There is a possibility that the winding of the coil may be disrupted due to disturbance in winding of the coil without being successfully sandwiched between the coil receiving surface 10 and the flat wire wound on the core shafts 71 and 72 previously.

  Therefore, as shown in FIG. 1, a mechanism unit 31 is provided for tilting the core shafts 71 and 72 together with the weight 9 in the direction opposite to the supply side of the flat wire 10.

  Here, a piston / cylinder mechanism 33 that moves the magnet 32 forward and backward is adopted as the tilting mechanism portion 31 so that the magnet 32 is attracted to the weight 9 and pulled.

  As shown in FIG. 4, when the winding core shafts 71 and 72 are inclined so that a gap s is formed on the supply side of the flat wire 10 when the coil is wound by the inclination mechanism portion 31, the supplied flat wire 10 is It becomes easy to be drawn into the gap s, and the coil can be wound up without collapsing the tight winding.

  At that time, the coil is effectively pressed by the dead weight of the weight 9 without a gap on the inclined side of the core shafts 71 and 72 so that the winding can be performed with good adhesion.

  In such an edgewise coil winding device, in the present invention, in particular, the following measures are taken so that the winding of the edgewise coil can be performed fully automatically without requiring manual operation. Yes.
