Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for manufacturing a coil for a magnetic levitation railway which constitutes an armature of a linear motor in a magnetic levitation railway.

[0002]

2. Description of the Related Art A conventional magnetic levitation railway coil of this type is a coil formed by winding a cable around a reel (not shown) as disclosed in, for example, Japanese Patent Laid-Open No. 3-124253. Since it is attached to the panel while being pushed out from the reel, if it is wound in multiple layers in order to secure the required number of windings, it tends to collapse. Therefore, the required number of turns is secured by increasing the number of axial stages of the coil by winding the coil in one layer.

However, increasing the number of coils in the axial direction in this manner increases the distance between the track on which the coil is mounted and the railway vehicle when used as a magnetic levitation railway coil. , It is necessary to reduce the vehicle width or widen the track spacing. However, reducing the vehicle width means lowering the transportation efficiency, and widening the track interval leads to an increase in construction cost.

In order to increase the number of windings without increasing the axial dimension of the coil, the windings should be increased in the radial direction of the coil.
That is, it is effective to increase the number of layers. Therefore, in Japanese Patent Application No. 2001-353747 filed by the same applicant as this application as prior art, the number of windings can be increased without increasing the axial dimension of the coil by adopting the configuration described below. Has been presented.

FIG. 6 is a front view showing the structure of a magnetic levitation railway coil in the prior art, FIG. 7 is a perspective view showing the structure of the coil housing member in FIG. 6, and FIG. 8 is a cable in the coil housing member in FIG. It is sectional drawing which shows the process of winding and forming a coil. In the figure, reference numeral 1 denotes a plurality of coil accommodating members arranged side by side, and a seat portion 1a, a winding core portion 1b projecting from a central portion of the seat portion 1a, and a predetermined interval around the winding core portion 1b. It is configured by an outer frame portion 1c formed so as to surround it and a coil housing portion 1d formed by being partitioned between the winding core portion 1b and the outer frame portion 1c. Reference numeral 2 denotes a plurality of coils housed in the coil housing portion 1d of each of the coil housing members 1 and having the same phase connected to each other via the transition portion 2a.

Next, the winding procedure of the coil 2 constructed as above will be described with reference to FIG. First, as shown in FIG. 8 (B), the winding start portion 2b of the coil 2 is drawn into the coil housing portion 1d, and is wound while the outer peripheral side is regulated by the outer frame portion 1c. As shown in), the first step is wound inward. Subsequently, in the second stage, as shown in FIG. 8E, while the winding core portion 1b is regulated on the inner peripheral side,
As shown in (F) and (G), the first coil is wound from the inner circumference side to the outer circumference side, and finally, as shown in FIG. 8 (G), the winding end portion 2c is pulled out from the coil housing portion 1d. 2 is completed. Then, the second coil accommodation member 1 is provided with a gap between the winding end portion 2e and the transition portion 2a, with two gaps left therebetween.
The coil 2 is drawn into the coil housing portion 1d and wound in the same manner as described above to sequentially form the coils 2 for the same phase.

[0007]

As described above, the conventional magnetic levitation railway coil has a number of windings in the radial direction of the coil 2,
That is, by increasing the number of layers, the required number of turns is ensured without increasing the axial dimension of the coil 2. However, in the coil housing portion 1d partitioned by the core portion 1b and the outer frame portion 1c, the outer frame portion 1c regulates the outer peripheral side from the outer peripheral side toward the inner peripheral side. Since the inner peripheral side is regulated by the portion 1b and the inner peripheral side is wound toward the outer peripheral side, it is not easy to mold a cable having relatively high rigidity, and it is very troublesome. However, there is a problem that productivity is deteriorated due to the increase in cost.

It is sequentially caught in the 1st side. Then, the n-layer coil member groups a ₂ and b ₁ were simultaneously formed and taken out from the inner side to the outer side on the second stage of the first winding frame 11 and the first stage of the second winding frame 11, respectively. The central portion of the cable 17 is left as a connecting portion w connecting the coil member groups a ₂ and b ₁ . Both coil member groups a ₂ and b formed in this way
₁ is fixed to the winding frame 11 in the same manner as the case of the coil member group a ₁ .

Thereafter, similarly to the case of the coil member groups a ₂ and b ₁ , the second stage of the second winding frame 11, the first stage of the third winding frame 11 and the second stage of the third winding frame 11 are carried out. The coil member groups b ₂ , c ₁ are wound by simultaneously winding the first stage of the fourth winding frame 11 and the second stage of the fourth winding frame 11 and the first stage of the fifth winding frame 11, respectively. Coil member groups c ₂ and d ₁ and coil member groups d ₂ and e ₁ are formed, respectively, and a crossover portion is provided between the coil member groups b ₂ and c _1, between c ₂ and d _{1, and} between d ₂ and e ₁ , respectively. w is left.

, Each coil 28 is connected by a transition portion w, and lead wires 1 are formed at both ends.

The coil 27 is attached to each reel 11 as described above.
When each is formed, the drum 16 is first removed from the rotary table 15, and then each winding frame 11 is removed together with the coil 27 as shown in FIG. And FIG.
After separating each winding frame 11 as shown in (B), the flange portion 13 of the winding frame 11 is attached to the winding drum 1 (not shown).

Although not shown, each of the coils 27 is fixed to a predetermined position on the wall surface of the track concrete of the magnetic levitation railway in a state of being connected to each other via the crossover w.

As described above, according to the first embodiment, the reels 11 are alternately driven to rotate in opposite directions via the rotary table 15, so that the reels 11 adjacent to each other are adjacent to each other. , The cable 17 stretched by applying a predetermined tension by the cable tensioning mechanism 24 is wound, and at the same time, it is wound in the rotation direction from the inner side to the outer side by a predetermined number of layers, and this is sequentially repeated, whereby each reel 11 is wound. 2 in the axial direction
Since the coil 27 is formed by winding a predetermined number of layers, the coil 27 can be easily formed, and the workability and the productivity can be improved.

Further, when the cable 17 is wound around the winding frame 11, the pressing roller 26 presses the cable 17 toward the center of the winding frame 11, so that the winding of the cable 17 does not swell and is more reliable. As a result, the reliability can be improved. Further, the distance between both ends of the cable 17 stretched around the cable tension mechanism 24 is maintained at the distance between the two adjacent stages of both reels 11 around which the cable 17 is wound by the distance maintaining mechanism 25. Therefore, the winding of the cable 17 can be surely performed at a predetermined position, and the reliability can be improved.

Embodiment 2. In this embodiment, a residual length detection sensor (not shown) that sequentially detects the remaining length of the U-shaped cable 17 from the length in which the cable 17 is wound is arranged in the pulley 19 in the first embodiment. The amount of tension applied to the cable 17 is controlled by rotating the rotating lever 18 according to the detected remaining length and changing the position of the tension roller 20. That is, when the tension is increased, the cable 17 is tightly and tightly wound, so that the length of the crossover portion w left at the end becomes long, and when the tension is decreased, the cable 17 is slightly loosely wound. Therefore, since the length of the crossover w becomes short, this relationship is used to reduce the tension when the remaining length is detected to be long according to the remaining length of the cable 17, and when the remaining length is short. If it is detected, the tension is largely controlled.

As described above, according to the second embodiment, when the cable 17 is wound around the winding frame 11, the remaining length of the cable 17 is sequentially detected, and the remaining length of the cable 17 is applied to the cable 17. Since the magnitude of the applied tension is controlled, the lengths of the crossovers w can be made equal to each other, so that each coil 27 is placed at a predetermined position on the wall surface of the track concrete of the magnetic levitation railway. When fixing each to
Since the length of the crossover w is short, it is not necessary to add another line, and it is not necessary to process a surplus line because the length is too long, so workability is improved and productivity is improved. You can

In the above construction, the remaining length is detected from the length of the cable wound on the side of the winding frame 11, but the present invention is not limited to this, and the rotary table 1 is not limited to this.
It is needless to say that it is possible to detect the remaining length by sequentially detecting the interval between the vehicle 5 and the carriage 22 and to obtain the same effect as the above.
