Description

Detailed Description of the Invention

Industrial application fields

  The present invention relates to a winding device for winding an edgewise coil.

  Conventionally, as a winding device that obtains an edgewise coil by winding a flat wire in the width direction, a fixed piece is attached to a circular core shaft that is rotationally driven by a motor so as to rotate integrally with the winding core. A presser piece that slides in the axial direction by a slide drive mechanism is provided on the shaft, and the flat wire that is sent with a certain tension applied by sandwiching the flat wire between the plates is fixed in the axial direction by the presser piece. A flat wire is wound around the core shaft between the fixed piece and the presser piece while applying pressure (see, for example, Patent Document 1).

  Japanese Patent Laying-Open No. 2001-71078 (see configuration in FIG. 2)

  In such a winding device, the fixed piece is removed from the core shaft, and the edgewise coil wound around the core shaft is pulled out. Since the edgewise coil is firmly wound around the core shaft while applying the pressing force in the axial direction by the presser piece to the coming rectangular wire, the wound edgewise coil can be removed from the core shaft. It has become difficult.

  Further, in a conventional winding device configured in the same manner as described above, a horizontal hole is made in one end portion of the core shaft, and a slit is cut in the axial direction from the hole to the other end. As a structure, by bending the core shaft so as to narrow the slit after winding the coil, the edgewise coil wound around the core shaft can be easily extracted (for example, a patent) Reference 2).

  Japanese Patent Laid-Open No. 2002-184639 (refer to the configuration of 11A and 11B in FIG. 1)

Problems to be solved by the invention

  The problem to be solved is that the presser piece that slides in the axial direction is provided on the core shaft, and the fixed piece is moved back and forth so that a constant pressing force is always applied according to the winding state of the flat wire. In order to wind the rectangular wire around the winding core shaft between the presser piece, a slide drive mechanism for retracting the presser piece according to the winding state of the flat wire is required, and the winding device The configuration is complicated.

  And in the conventional winding device, after winding the edgewise coil, the fixed piece screwed to the core shaft is removed, and then the edgewise coil is removed from the core shaft. Is complicated, and it is difficult to remove the edgewise coil firmly wound around the core axis.

  In addition, a slit is formed in the axial direction of the core shaft so that the edgewise coil wound around the core shaft can be easily removed, and the core shaft is narrowed so that the slit is narrowed. If the edgewise coil is pulled out by bending, the slit is formed and the rigidity of the core shaft itself is lost, making it impossible to wind the edgewise coil firmly. There is a problem of end.

Means for solving the problem

  The present invention is a winding device for winding an edgewise coil, and with a simple configuration, the edgewise coil can be firmly wound around a core shaft and can be easily removed. I try to take measures that I can do.

  Specifically, a rotating shaft that is vertically arranged and rotates with a motor as a driving source, and two that are inserted from above into a plurality of holes that are formed at intervals in the axial direction of the rotating shaft. The winding shaft is composed of a core shaft and a weight attached to the upper portion of each of the core shafts provided in a pair, and a rectangular wire sent in the horizontal direction is rotated along the upper end surface of the rotating shaft. A rectangular wire is wound around the core shaft while being sandwiched between the upper end surface of the shaft and the weight and pushing up the core shaft together with the weight by rotation of the rotating shaft.

  In particular, in order to obtain a structure that can further increase the rigidity of each of the core shafts provided in a pair during coil winding, a hole with a flat cross-sectional shape is formed in the axial direction of the rotary shaft provided vertically The two core shafts are inserted into the hole portions from above, and the spacers are inserted in the gaps between the core shafts so as to be freely inserted and removed.

  In the winding device according to the present invention, as shown in FIG. 1, a rotating shaft 3 whose main body portion is rotatably arranged in a vertical direction by a bearing 2 screwed to the upper portion of the gantry 1; The pulse motor 4 screwed to the lower part of the gantry 1, the coupling 5 that connects the rotary shaft 3 and the rotary shaft 41 of the pulse motor 4, and the axial direction of the rotary shaft 3 are formed at intervals from each other. The two core shafts 71 and 72 that are loosely inserted into the holes 61 and 62 (see FIG. 2) from above and the upper portions of the pair of core shafts 71 and 72 are detachably mounted by the set screw 8. And a weight 9 (see FIG. 3).

  Further, the upper end surface of the rotating shaft 3 is used as a coil receiving surface, and a receiving table 11 is disposed so that the receiving surface of the flat wire 10 comes to be horizontal with the coil receiving surface. A weight 12 is guided on the receiving table 11. 13 is provided in the supply system of the flat wire 10, and the flat wire 10 is sandwiched between the cradle 11 and the weight 12 in the thickness direction so that it can be wound. Tension is generated.

  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.

  Therefore, the tension mechanism 14 can apply a constant tension to the flat wire 10 with a simple structure and without any variation.

  A pressing member 16 that restricts the flat wire 10 to the upper end surface of the rotating shaft 3 is provided in the vicinity of the upper end surface of the rotating shaft 3 so as to suppress pulsation in the thickness direction of the sent flat wire 10. ing.

  In the winding device having such a configuration, a constant tension is applied by the tension mechanism unit 14 and is pressed by the pressing member 16 to be fed in the lateral direction along the coil receiving surface (upper end surface) of the rotating shaft 3. The rectangular wire 10 is tentatively fastened with a screw 19 provided on the side surface of the weight 9 and the rectangular wire 10 is attached to the coil receiving surface of the rotating shaft 3 and the weight 9 by the dead weight of the weight 9. When the rotary shaft 3 is rotated after being sandwiched between the two, a rectangular wire is wound around the pair of core shafts 71 and 72 while pushing up the core shafts 71 and 72 together with the weight 9 according to the rotation. 10 is wound.

  When the desired edgewise coil 17 is obtained by winding a predetermined number of the rectangular wires 10, the pair of core shafts 71 and 72 around which the edgewise coil 17 is wound are placed above the rotating shaft 3 together with the weight 9. Pull out. In this state, the edgewise coil 17 is heat-sealed by being set in the heat-sealing jig of the next process.

  After the fusion, as shown in FIG. 4, the edgewise coils 17 are wound around the pair of core shafts 71 and 72 to which the weight 9 is attached, and the core shafts 71 and 72 can be freely moved. The edgewise coil 17 can be easily pulled out by applying an external force F from both sides to the end portion and bending it in the opposite direction to create a gap between the core shafts 71 and 72 and the edgewise coil 17. .

  Further, when the rectangular wire 10 is wound with a relatively strong tension, each of the core shafts 71 and 72 is not bent so that the pair of core shafts 71 and 72 provided with a gap therebetween is not bent. In the case where the rigidity is increased, the set screw 8 is loosened and the weight 9 is removed, and then an external force is applied to the free end portions of the core shafts 71 and 72 so as to narrow the gap, thereby the edge. The width coil 17 can be easily extracted.

  FIG. 5 shows an edgewise coil 17 wound by a winding device according to the invention.

  6 and 7 show other examples of the configuration of the winding device according to the present invention.

  Here, in particular, when the edgewise coil 17 can be easily pulled out by bending the winding cores 71 and 72, a pair is formed when the rectangular wire 10 is wound with a relatively strong tension. In order to prevent the provided winding shafts 71 and 72 from being bent, a hole 6 having a flat cross section is formed in the axial direction of the rotary shaft 3 provided vertically, and the holes 6 are respectively formed in the holes 6. After the two core shafts 71 and 72 are inserted from above, the spacer 18 is removably inserted into the gap between the core shafts 71 and 72.

  According to such a structure, when the flat wire 10 is wound, since the space between the core shafts 71 and 72 provided in a pair is compensated by the spacer 18, the core shafts 71 and 72 do not bend, The rectangular wire 10 to which a relatively strong tension is applied can be wound firmly.

  After the winding, the pair of core shafts 71 and 72 and the spacer 18 around which the edgewise coil 17 is wound are pulled out above the rotating shaft 3 together with the weight 9, and after the heat fusion, the spacer The edgewise coil 17 can be easily pulled out by pulling 18 downward and deflecting the free end portions of the core shafts 71 and 72 in opposite directions.
