Abstract

PURPOSE:To prevent the damage of a coil by providing a presser made of a projection having a plurality of notches in which a coil is engaged on the pressing surface of a pressing plate. CONSTITUTION:After upper and lower coils 9A, 9B are suspended on a coil feeding jig, the jig is engaged with a coil inserting device. When a pressing plate 3 is then slid downward, the coil 9A is pressed only by the plate 3, the coil 9B is pressed by pressers 12A and 12B, and the upper and lower coils are suspended and fed to the coil inserting device without contact with each other. Then, when the jig is removed, the coil feeding is completed. As described above, the pressers are provided on the pressing plate to feed the coil affected by a force each other when the coils of plural layers having a crossing point are suspended and fed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a coil transfer jig for transferring a coil to a coil insertion device for inserting a coil of a rotating electric machine into an iron core slot.

Conventional configuration and its problems In recent years, when inserting a coil in a rotating electrical machine into a core slot, a single-winding machine is used to wind a coil in a predetermined shape in advance, and the coil is suspended and inserted into a coil transfer jig. However, after transferring this to a coil insertion device, it is inserted into the core slot.

The conventional coil transfer jig as described above will be described below with reference to the drawings.

FIGS. 1 and 2 show the structure of a conventional coil transfer jig. In FIGS. 1 and 2, reference numeral 1 denotes bottles arranged in a cylindrical shape at predetermined intervals, and one end of which is fixed to a fixed quartet 2. 3 is a suppression plate that has a plurality of notches 3A inside and is slidable along the bottle 1. Note that a shaft 4 is attached to the fixed plate 2 on the opposite side to the attachment surface of the bottle 1.

On the other hand, the coil insertion device has a blade 5 as shown in FIG. 3a.
．． Wedge guide 6, base 7. It consists of a stripper 8. A plurality of blades 5 are arranged in a cylindrical shape at predetermined intervals on the base 7, and one end is fixed to the base 7. A slipper 8 having a plurality of notches that engages with the blade 5 is arranged inside the slipper 8 and is capable of sliding along the blade 5. A wedge guide 6 is fixed to the fundamental tone 7 on the outside of the blade 5 in the same manner as the blade 5.

The operation of the coil transfer jig constructed as described above and an example of the coil insertion force method will be described below.

First, if the coil is suspended and transferred to the coil transfer jig, the coil 9 wound on the winding frame by the winding machine is transferred by combining the winding frame and the coil transfer jig, or the coil 9 is transferred to the winding frame This is done by a method such as binding the coil 9 wound on the winding frame with a ribbon or the like and removing it from the winding frame, and then manually transferring and destroying the coil 9 to a coil transfer jig. .

To transfer the coil 9 from the coil transfer jig to the coil insertion device, while holding the coil 9 and the shaft 4 of the coil transfer jig by hand, insert the coil transfer jig as shown in FIG. Push down the bottle 1 along the outer peripheral surface of the blade 5 of the coil insertion device until the wedge guide 6 and the bottle 1 are combined. Next, as shown in FIG. 3, by pressing down the pressing plate 3 to the tip of the wedge guide 6, the coil 9 is transferred from the coil transfer jig to the coil insertion device. Thereafter, the coil transfer jig is pulled up along the outer peripheral surface of the blade 5 of the coil insertion device, and the coil transfer jig is removed.

Next, the core guide 10 is fitted into and supported at the tip of the blade 5 of the coil insertion device. By aligning the inner circumferential surface of the stator core 11 with the outer circumferential surfaces of the core guide 10 and the blades 5,
The stator core 11 is inserted up to the wedge guide 6 and fixed. Next, slide the stripper 8 upward to push up the coil 9 and move the stator core 1 as shown in FIGS. 3C and 3D.
1, the coil 9 is inserted into the slot 11A. During this process, the core guide 1o is pushed upward and removed automatically or manually. After inserting the coil 9 into the slot 11A of the stator core 11, the stripper 8 is pulled back to its original position and the stator core 11 is pulled out from the blade 5, thereby completing the coil insertion process.

However, with the above configuration, if the coils 9 do not intersect as shown in FIG. 4, the coils 9 can be transferred to the coil insertion device well, but as shown in FIG. If there is a crossing point, good transfer cannot be performed. For example, upper coil 9A and lower coil 9B
If they intersect, the pressing force of the suppression plate 3 is transmitted to the upper coil 9A, and then to the lower mlll coil 9B.

Therefore, the lower coil 9B is pushed down by the upper coil 9A, and when the volume of the coil 9 increases, the upper coil 9B
The disadvantage is that the coil 9 is damaged at the intersection of the 4111 coil 9A and the Do1 law coil 9B, or at the contact surface between the coil 9A and the pressing plate 3, making it impossible to carry out a good coil transfer.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, the present invention provides a coil transfer jig that can transfer coils to a coil insertion device well even when there is a crossing point between the coils.

Structure of the Invention In order to achieve this object, the coil transfer jig of the present invention has the following features:
The coil is equipped with a presser consisting of a protrusion having a plurality of notches into which one coil is completely fitted on the pressing surface of the pressing plate, and by independently providing a pressing surface that presses the upper coil and the lower coil. Even when there is a crossing point between the coils, no pressing force is applied between the coils, so that good coil transfer can be achieved.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

6 to 8 show an example of the structure of the coil transfer jig of the present invention. In FIG. 6, reference numeral 1 denotes bottles arranged in a cylindrical shape at predetermined intervals, and one end of which is fixed to a fixing plate 2. A shaft 4 is attached to the fixed plate 2 on the side opposite to the attachment surface of the bottle 1. 3 has a plurality of notches 3A inside,
This is a suppression plate that can be slid along the bin 1. On the bottle 1 side surface of the suppressor plate 3, a suppressor 12A having a plurality of protrusions on the outside of the pin 1 and a suppressor 12B having a plurality of notches on the inside of the pin 1 are arranged at predetermined positions on the presser plate 3. is fixed in position, and slides according to the movement of the suppression plate 3. As shown in FIG. 7, the presser 12A and the presser 12B are formed so as to press only the lower coil 9B.

As shown in Figure 8a, the upper coil 9 is placed on the coil transfer jig.
A. After suspending the lower coil 9B, place the coil transfer jig on the coil insertion side! i, V (engaged). Next, as shown in FIG.
Then, the upper coil and the lower coil are transferred to the coil insertion device 1°'t by 1°IW without contacting each other.

Thereafter, the coil transfer is completed by removing the coil transfer jig.

Effects of the Invention As described above, the present invention has a feature that, by providing a presser on the press plate, the coils receive force from each other even when multi-layer coils having mutually intersecting points are suspended and transferred. It can be transferred without any trouble. Therefore, the coil is not damaged and good coil transfer can be achieved, which has significant practical effects.
