Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for winding a convex pole type iron core, and in particular to a method for winding a convex pole type iron core in a manner that prevents the winding from collapsing when winding the convex pole type core of rotating equipment. The present invention relates to a method of winding a convex pole type iron core.

[Prior art and problems to be solved by the invention] Conventionally, when a winding machine is used to wind a convex pole iron core of a rotating device, the flyer arm generally does not wind the winding due to the nature of the winding machine. Windings are sequentially applied around the outer periphery of the convex pole iron core to be applied. Therefore, for example, when the rotor core 1-1 has a winding region 2-1 having a rectangular cross-sectional shape in the winding direction as shown in the cross-sectional view of FIG. The wire rod 3 may be repeatedly wound in a sequentially laminated manner from one end of the winding region 2-1 to the other end.

However, when the opening in the winding direction of the wire 3 is narrow or the winding area has a complicated shape, it is difficult to wind the wire 3 in the winding area 2-1 having a rectangular cross-sectional shape. If the winding method is similar, it will not be possible to wind the wire in an orderly manner. As a result, the occupation rate of the wire becomes small and the winding state becomes unstable, resulting in the problem that loose wires sometimes occur. For example, the fourth
As shown in Figure B, if there is a lateral spread in the bottom part of the winding area 2-2 provided on the rotor core 1-2, the winding area 2-2 is sequentially spread from one end to the other from the bottom part of the winding area 2-2. If the wire material 3 is repeatedly wound in a layered manner toward the ends, there is a problem in that a bulge occurs in the central part at the top as shown in the figure, and furthermore, the winding wire collapses and a so-called loose wire occurs. Ta.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention divides the winding area into a plurality of block layers when winding a convex pole iron core of a rotating device, When winding each block layer in the divided winding area, a method is adopted in which both ends of each block layer are wound in a so-called embankment manner, and then the central portion is wound, thereby achieving orderly winding. It consists in applying lines. Therefore, the method for winding a convex pole core of the present invention requires a mounting base for mounting the convex pole core to be wound, and a coaxial and axial direction of the convex pole core attached to the mounting base. a flyer arm arranged so as to be relatively movable, the flyer arm being rotated around the outer periphery of the convex pole core to wind the convex pole core. In the winding method, the winding area for winding the wire around the convex pole iron core is divided into a plurality of block layers, and the flyer arm is used to wind each block from the lowest block layer of each of the divided block layers. By first forming a plurality of winding layers on the side blocks at both ends of the layer and then winding them, and then winding the central block, the process is repeated for a predetermined number of block layers for each block layer, thereby creating a convex pole iron core. The wire is wound by forming a plurality of block layers in the winding region of the wire.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figure 1 is a winding diagram showing the winding method of the present invention, Figure 2 is a winding diagram showing the winding method of the present invention;
FIG. 1 is a block diagram of a winding machine using the winding method of the present invention shown in FIG. 1. FIG. 3 shows an application example using the winding method of the present invention shown in FIG.

In the figure, 1-1 to 1-5 are rotor cores, 2-1
2 to 2-5 are winding areas, 3 is a wire rod, 4 is a guide, 5 is a flyer arm, and 6 is a winding head.

In FIG. 1, the numbers "1" to "15" in the winding region 2-3 provided on the rotor core 1-3 in the figure indicate the winding order. The winding order number “1” to “1”
5'', the winding method of the present invention divides the winding area 2-3 into a plurality of block layers. 3”, “4” to “6”, “7” to “9”, “10” to “12” and “1”
It is divided into five block layers consisting of 3" to 15" blocks.Hereinafter, the "block layers" will be simply referred to as "layers" for ease of expression. When winding a wire, the winding wire is wound in layers starting from the lowest layer with a height corresponding to a single winding diameter.
If it is necessary to express the term "winding layer" in this specification, it will be referred to as a "winding layer" to distinguish it from the above-mentioned "block layer". Then, each divided layer is further divided into an end block (hereinafter referred to as an end part for simplicity) and a central part block (hereinafter referred to as a center part for simplicity), and the end parts on both sides are wound first. After turning, wrap the center part.
That is, after first winding the ends of each layer to create a so-called embankment and fixing the wire in a manner that prevents the winding from collapsing, etc., the wire is embedded in the center and wound so that it becomes almost flat. ing. For this reason, it is possible to wind the wire in an orderly manner without creating a bulge in the central portion of the winding shown in FIG. 4B as in the conventional case.

In FIG. 2, the rotor core 1-4 in the figure constitutes a convex pole type iron core, and a wire 3, for example, a magnet wire, is wound by a flyer arm 5 along the dotted lines according to the winding order number shown in FIG. It is wound in the winding area 2-4 shown by. The flyer arm 5 is attached to a winding head 6 of a winding machine (not shown) in the manner shown. For this reason, the flyer arm 5 follows the rotation of the winding head 6 and moves around the outer periphery of the rotor core 1-4 in a circular arc while winding the wire 3 in the winding area shown by the dotted line inside the rotor core 1-4. Wind it 2-4. At this time, the position of the winding head 6 is controlled by a servo system using a microphone processor in order to wind the wire 3 in a position matching the winding order number shown in FIG. In this control, the program origin shown in FIG. 1, for example, the right end position in the winding area 2-3 shown in FIG. After the wire 3 is wound around the rotor core 1-4 a predetermined number of times, it is configured to automatically move to the position of the next winding order number. At this time, the number of windings at each winding order position may be determined by calculation, but it is better to find the number of windings that can provide the optimum winding by experiment. Fine winding control becomes possible. Note that the guide 4 in the figure is used to prevent the wire 3 from protruding outside the winding area 2-4 when the flyer arm 5 is used to wind the wire.

Next, the winding control will be explained in detail using FIG. 3.

FIG. 3 shows a first
This shows the state in which the layers, that is, blocks "1" to "3" in FIG. 1, are wound.

As the first step, at the “0 mm” position shown in the diagram,
That is, the wire is wound 40 turns in such a manner that a plurality of winding layers are present at the position corresponding to block "1" in FIG. 1 (the origin of the program shown in FIG. 2). The state of the winding is shown in the figure "1" in the winding area 2-5.

As a second step, the wire is wound 40 turns at the "40 mm" position shown in the figure (the position corresponding to block "2"). The state of the winding is shown in the figure "2" in the winding area 2-5.

As the third step, move it to the “0mm” position shown in the diagram.
Immediately after winding 40 turns, move to the “20mm” position shown in the diagram.
It is wound 20 turns. The state of the winding is shown at "3" in FIG. 3 in the winding area 2-5. In the third step, the wire was wound for 40 turns at the initially indicated "0 mm" position to obtain a winding mode that gave a good winding condition based on the experimental results. If the wire is wound at the "0 mm" position shown in FIG. 3, the result will be the same as when the wire is wound at the "3" position shown in FIG. It goes without saying that
When winding around block "1" and then winding around block "2", there will be a so-called crossing line, and when winding block "3" afterwards, there will be a crossing line. However, since the crossing wire is one wire and there is some slack, there is no problem even if the wire is overlapped. in this way,
Similarly, for the second layer, third layer...
After winding each layer in the form of building embankments at both ends, the central portion is wound, and the number of turns to be wound at each position is determined as appropriate by taking into account conditions such as the shape of the winding area 2-5 and the winding position. By setting the optimal value determined by , it becomes possible to wind a good winding wire.

〔Effect of the invention〕

As explained above, according to the present invention, when winding a convex pole iron core of a rotating device, the winding area is divided into a plurality of layers, and a so-called embankment is built on both ends of each of the divided layers. Since the winding process is repeated in sequence, such as winding the wire in the central part and then winding the central part, it is possible to wind the wire in a manner that matches the shape of the winding area, and it is possible to perform the winding in an orderly manner. Therefore, it is possible to provide a stable winding with a large occupation rate.
