Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for winding a coil, such as a coil for a transformer, in which a winding coil section and a winding coil section are alternately arranged, using a vertical shaft winding machine. and devices.

Generally, such a coil is made by repeatedly winding a winding coil part 2 and a winding coil part 3 around a winding core 1 of the coil in an alternating and continuous manner to form a coil circuit a, as shown in FIG. 1 of the accompanying drawings. are doing. Conventionally, as shown in FIG. 2, the winding of the unwinding coil part 3 of the coil is performed by temporarily winding b around the circumference of the winding core 1 of the coil by winding rotation C, and then By unwinding and rotating only the winding core 1 d without rotating the temporary unwinding coil part 3' which has been temporarily wound b, the temporary unwinding coil part 3' is unwound and the unwinding coil part 3 is unwound. In this way, the unwinding coil part 3 is formed, and then the next winding coil part 2 is formed again by the winding rotation c.
The winding method used was to wind up the wire.

According to such a winding method, in addition to requiring a large space in the pre-unwinding coil section 3' for pre-winding b, it is also necessary to separate the winding rotation c and the unwinding rotation d which is reversed thereto. It has many disadvantages, such as the need to repeat the process many times alternately, and the need for a lot of time to reload the temporary unwinding coil section 3' into the unwinding coil section 3. Traditional winding methods had.

The present invention improves the drawbacks of the conventional methods as described above, and uses a vertical shaft winding machine that only winds and rotates the vertical shaft winding and reduces the space required for the pre-unwinding coil section. It is an object of the present invention to provide a method for winding a coil and an apparatus therefor.

In order to achieve this object, the present invention provides a winding method in which a conductor of a length necessary for winding a winding coil section is placed in a radial direction on the outer periphery of a winding coil section preceding the winding coil section. The final end of the conductor of the pre-unwound coil part is temporarily wound by rotating in the same direction as the winding of the pre-wound coil part to form a pre-unwound coil part, and the final end of the conductor of the pre-unwound coil part is wound on the winding core. a step of guiding the unwinding coil section to a position where it is to be installed, rotating in the same direction as the above rotation direction, and winding and moving the tentatively wound conductor of the temporarily unwinding coil section to a predetermined installation position of the unwinding coil section; The device for carrying out this winding method is a temporary winding device that rotates together with the rotating table at a predetermined position without moving up and down, and is set so that the winding core passes through the center of the rotating table. A guide part is provided, and the temporary winding guide part is rotatable with respect to the rotary ring, which rotates with the rotary table at a predetermined position without moving up and down, and to either the inner diameter or the outer diameter side of the rotary ring. An adjustment ring provided,

It is characterized by being comprised of a connecting plate that connects the plates so that they can approach and separate from each other in the circumferential direction.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings showing one embodiment of the apparatus of the present invention.

In FIG. 3 of the accompanying drawings showing an example of a state in which the temporary winding guide section according to the present invention is set in a vertical shaft winding machine, the winding core 10 of the coil is attached to the rotary table 11 of the winding machine at its lower part, The rotary table 11 is attached to the output shaft of a drive device 12, and this drive device 12 is attached to a rotary table mount 13. This rotary table mounting base 13 is provided with a female ball screw (not shown) that is driven by the drive device 12, and a male ball screw 1 that is engaged with this female ball screw.
4 is supported by a fixed part, for example, the bottom of a pit 16, via a bearing 15 provided at its lower end, and the rotary table mount 13 moves up and down by the rotation of the female ball screw.

On the other hand, a support 19 with a roller 18 attached thereto is fixed on a scaffold 17 above the pit 16, and the winding core 10 is formed of a rotating ring 20, etc., through which the core 10 passes through the center. A tentative winding guide section 21 is rotatably supported on the support column 19. As the winding advances, the rotary table mount 13 is slid up and down in the direction of arrow g by the male ball screw 14 to move the winding core 10 up and down.

Furthermore, since the tentative winding guide section 21 composed of the rotary ring 20 and the like needs to rotate integrally with the rotary table 11 without moving up and down, The storage rod 22 and the transmission rod 23, which has its upper end set in the rotation ring 20, is inserted into the transmission rod storage rod 22, and is configured to be able to move up and down (as indicated by the arrow f), allow the winding core 10 and the rotation table to be connected to each other. 1
It is held by the rotary ring 20 so as to rotate integrally with the rotation of the rotary table 11 without moving up and down despite the first-class vertical slide.
Therefore, the winding rotation c of the rotary table 11 is caused by the rotation of the transmission rod storage rod 22 set on the rotary table 11.
is transmitted to the rotary ring 20 by the transmission rod 23, and the tentative winding guide section 21 composed of the rotary ring 20 etc. is transmitted to the rotary table 11 of the vertical shaft winding machine.
It is designed to rotate in sync with the

Next, FIGS. 4 and 5 show an embodiment of the winding device according to the present invention, in particular, the temporary winding guide portion 21 thereof.
In the figure, reference numeral 10 indicates the winding core of the coil, 2 indicates the winding coil portion, and 3
3'' is a temporary unwinding coil portion that is temporarily wound before forming the unwinding coil portion 3, and 18 is a roller, which are the same as shown in FIGS. 1 to 3. It is the same as the one with the sign.

Now, to explain in detail the configuration of the temporary winding guide section 21, there is an adjustment ring 24 on the inner diameter side of the rotary ring 20 that rotates to adjust the relative position with the rotary ring 20, and two links 25. is held by a pin 26 at its center, and a fixed bearing 2 set in the rotating ring 20.
7 and the moving bearing 2 set in the adjustment ring 24.
8, one end of each is pin-coupled by a pin 29, and the other ends of both links 25 are
Each of them is pin-coupled to a separate coil receiving plate 30 by a pin 29.

Since the temporary winding guide section 21 of the invention is configured in this manner, in order to adjust the coil receiving plate 30 in accordance with the coil outer diameter k, the adjustment ring 24 is moved i and the link 25 is This is done by moving j. In addition, two coil receiving plates 30 are connected to a link 25 whose intermediate portion is connected by a pin.
is held by pins 3 provided on each coil receiving plate 30.
This is done by a connecting plate 32 which has a sliding groove formed in the circumferential direction through which the coil receiving plate 30 slides. The adjustment ring 24 is tightened and fixed to the rotary ring 20 by the holding plate 33 and the set screw 34, thereby holding and fixing the coil receiving plate 30 in a fixed position. In addition, each coil receiving plate 30 is formed with a receiving part 35 on which the temporary unwinding coil part 3'' is placed in the radial direction and facing outward.

The device of the present invention is constructed as described above, and the winding method will be explained next along with the operation of the device of the present invention.

When winding of the winding coil portion 2 around the winding core 10 of the coil is completed, the coil conductor 36 is placed onto the receiving portion 35 of the coil receiving plate 30 by the winding rotation c of the vertical shaft winding machine, which is the same rotational direction. Winding is performed in the radial direction, and a temporary unwinding coil part 3'' having the same length as the conductor length of the unwinding coil part 3 is temporarily wound.Next, the coil conductor 36 at the final end of the temporary unwinding coil part 3'' is wound. The winding core 10 is fixed at the installation position of the unwinding coil part 3 on the winding core 10 so as to be slidable with respect to the rotation of the winding core, and in this state, the vertical shaft winding machine is driven to move the winding core 10 in the same rotation direction. Winding rotation Rotates in direction c.
In this way, the winding core 10 at the final end of the coil conductor 36
By rotating under the fixation that can freely slide upward, the temporarily unwound coil part 3'' is placed on the coil winding core 10 from the final end side to the starting end side of the temporarily unwound coil part 3'', that is, , the coils are sequentially moved toward the continuous part with the preceding winding coil part 2, and winding of the winding down coil part 3 is completed.

The present invention uses such a winding method and operation to wind a coil in which the winding coil parts 2 and the winding coil parts 3 are arranged alternately, for example, the winding work of the winding coil part of a transformer coil. By making the rotation direction of the core the same, it is possible to increase the speed, and by setting the temporary unwinding part not in the axial direction of the core,
Since the temporary winding is performed in the radial direction on the outer diameter of the preceding winding coil section, the space for temporary winding can be extremely small.Furthermore, the temporary winding guide section does not move up and down, and the temporary winding is performed as described above. The present invention has many remarkable effects, such as winding work being carried out in the radial direction, which allows the winding work to be done at the same height, thereby stabilizing the work posture.

In the above embodiment, the direction of rotation of the winding rotation is indicated by the arrow c, but of course the direction is not limited to this, and the direction opposite to this, that is, the direction indicated by the arrow in FIG. It may be provided in the d direction, or it may be provided on the outer diameter side of the adjustment ring. In either case, there is no difference in the winding method, device, or effect from the effect of the above embodiment.
