Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil winding device for winding a coil often used in a high voltage winding of a molded transformer.

[0002]

2. Description of the Related Art A strip coil has a thickness of 1 mm or less and a width of 100.
It is formed by stacking strip conductors of about mm in the radial direction with an insulating film sandwiched between them and winding them for a specified number of turns, and then stacking them in the axial direction and connecting them in series to form a single unit. It is used in high voltage windings. The insulation film that insulates between the strip conductors is as thin as several tens of μm, so if a foreign object of this thickness gets into the strip coil, the insulation film will be damaged and the insulation strength will drop extremely, resulting in an insulation test. This may cause a dielectric breakdown at the time, or cause a serious problem that this portion is burned when a voltage is applied to the mold transformer by short-circuiting between the strip conductors. Therefore, great care is taken to prevent foreign matter from entering the winding of the coil.

In the conventional coil winding device, a felt cleaner belt is kept in contact with the coil conductor on the path line of the coil conductor from the coil reel of the coil conductor to the coil frame of the coil coil so that foreign matter can be attached to the coil conductor. When it adheres, it is wiped off with this cleaner belt. The cleaner belt is equipped with the tip of the felt wound in a roll on one shaft on the other shaft and rotating this shaft to wind it little by little to move the part that comes into contact with the strip conductor so that it always becomes a strip conductor. Is in contact with a fresh cleaner belt and this winding is done manually by the winding operator.

[0004]

Since the worker manually winds the cleaner belt, the worker forgets that the cleaner belt is too dirty and the foreign matter removing function is deteriorated or the foreign matter is attached. There is a problem in that the strip conductor may be scratched.

An object of the present invention is to solve such a problem, to automatically move the cleaner belt, and also to automatically remove foreign matter adhering to the cleaner belt, thereby maintaining a constant foreign matter removing function. It is an object of the present invention to provide a strip coil winding machine equipped with a foreign matter removing device capable of performing the above.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a winding frame of a strip conductor having a predetermined thickness and width, which is wound in a radial direction so as to form a strip coil. To a coil winding frame, the strip coil winding apparatus is provided with at least one foreign matter removing device that is installed in a strip conductor path line and that removes foreign matter that comes into contact with the strip conductor and adheres to the strip conductor. Ring-shaped cleaner belts arranged on both sides of the strip conductor, belt rollers for rotating these cleaner belts, driving mechanism for driving the belt rollers, and contact with the strip conductor and the cleaner belt from both sides with a predetermined pressure Belt press to let, and
A foreign matter suction device is provided at a position on the opposite side of the belt retainer in the vicinity of the belt cleaner to suck foreign matter adhering to the cleaner belt.

[0007]

In the structure of the present invention, a ring-shaped cleaner belt is provided which is arranged on both sides of a strip conductor and which is rotated by a belt roller driven by a drive mechanism. The cleaner belt and the strip conductor are sandwiched by the belt retainer from both sides. The foreign matter adhered to the strip conductor is transferred to the cleaner belt by contacting it with a predetermined pressure at, and the cleaner belt is rotated by the belt roller so that the foreign matter is not concentrated in one place or scratched on the strip conductor. In addition, the foreign matter suction device is provided on the side opposite to the position where the belt retainer is provided, and the foreign matter adhering to the cleaner belt is sucked up, so that the cleaner belt in contact with the strip conductor is held in a state in which the foreign matter is not adhered.

EXAMPLES The present invention will be described below based on examples.
FIG. 1 is an elevational view of a strip coil winding device showing an embodiment of the present invention. In this figure, the coil winding device 100
Is a strip conductor 5 wound in a coil and carried in from the manufacturer.
The winding conductor 11 for mounting the winding conductor 11, the winding machine 11 for mounting the winding reel 1 of the winding coil, and the pass line through which the winding conductor 5 passes between the coil winding frame 1 and the winding conductor winding 4 mounted on the winding machine. A plurality of undesignated rollers provided in the middle of 50, two sets of the foreign matter removing device 3 and the strip conductor 5 provided in the middle of the pass line 50 are inserted between the windings as the strip coil 2 And an insulating film supply device 6 for supplying an insulating film for maintaining insulation between the strip conductors 5. The motors and transmission mechanisms that drive these are hidden in the device and are not shown.

When the coil bobbin 1 rotates, the strip conductor 5
The insulating film 61 and the insulating film 61 are wound up and stacked in the radial direction. After winding a predetermined number of turns, end treatment is performed so as not to rewind, and then the coil 2 is removed from the coil winding frame 1 and another coil 1 is newly wound. The foreign matter attached to the strip conductor 5 is removed by the two foreign matter removing devices 3. The foreign matter on the insulating film 61 is removed by a foreign matter removing device (not shown) provided in the insulating film supply device 6.

FIG. 2 is a partial perspective view showing details of the foreign matter removing device 3 of FIG. In this figure, the foreign matter removing device 3 is composed of a pair of devices provided above and below the strip conductor 5, and the above device will be described. The foreign substance removing device 3 is composed of a ring-shaped felt provided in contact with the strip conductor 5. A cleaner belt 31 for removing foreign matters attached to the belt, a pair of belt rollers 32 for rotating the cleaner belt 31, a belt holder 34 for pressing the cleaner belt 31 against the linear conductor 5, and a cleaner belt 31 provided on the opposite side of the belt holder 34 It includes a suction device 35 for sucking the adhering foreign matter, and a drive mechanism 38 including a motor 36 for driving the belt roller and a transmission unit 37. The structure of the suction device 35 after the illustration is omitted. As described above, the configuration below the foreign matter removing device 3 is also symmetrical to the above configuration.

The strip conductor 5 and the cleaner belt 31 move as shown by arrows in the figure. The moving speed of the strip conductor 5 is 20 to 3
It is about 0 m / s. On the other hand, the cleaner belt 31
The moving speed of the cleaner belt 31 may be much slower.
The speed may be such that foreign matter attached to the strip conductor 5 moves to such an extent that the foreign matter does not penetrate between the strip conductor 5 and the cleaner belt 31 and damage the strip conductor 5. As described above, in the conventional apparatus, it is sufficient that the worker intermittently moves the cleaner belt.

When the foreign matter adhering to the linear conductor 5 moves to the cleaner belt 31, it moves with the movement of the cleaner belt 31 and reaches the tip of the sucker 35. In this portion, since the speed of the air sucked into the sucker 35 is high, the foreign matter adhered to the cleaner belt 31 is separated from the cleaner belt 31 and sucked therein. The foreign matter that could not be removed here is also removed before coming out from the tip of the suction device 35 on the opposite side, and the cleaner belt 31 coming out from here is in a clean state with no foreign matter attached.

Therefore, the cleaner belt 31 immediately before coming into contact with the strip conductor 5 is always maintained in a clean state, so that stable winding work can be continued for a long period of time. In addition, since the worker does not need to move the cleaner belt, the worker can concentrate on other work, and forgetting to move the cleaner belt causes foreign matter adhering to the cleaner belt 5 to get in between. The strip conductor 5 is not damaged.

Although the foreign matter removing device 3 is provided at two locations in FIG. 1, it may be provided at only one location if the foreign matter removing function is sufficient. Further, the shape of the sucking portion of the sucking device 35 is shown in FIG.
It does not stick to a shape with a wide tip as shown in Fig. 2 and Fig. 2. Various types can be used like the suction section of a commonly used vacuum cleaner, and it is also possible to adopt a configuration that hits the cleaner belt 31 or gives vibration to ensure the detachment of foreign matter. It is possible.

As the drive mechanism 38, a dedicated motor 36 and a transmission unit 37 are shown in FIG. 2, but the cleaner belt 31 may be moved at a low speed as described above, and therefore the rotation speed of the belt roller may be small. Therefore, since the power for driving them is small, a drive mechanism different from that shown in the drawing can be adopted. In any case, it is possible to adopt any configuration including the above-mentioned configuration of the suction unit 35, which is not shown, within a range not deviating from the object of the present invention.

[0016]

As described above, the present invention has a ring-shaped cleaner which is arranged on both sides of a strip conductor passing through a pass line which is a passage through which the strip conductor passes and which is rotated by a belt roller driven by a drive mechanism. A belt is provided, and the cleaner belt and the strip conductor are sandwiched from both sides by a belt presser and brought into contact with each other at a predetermined pressure to wipe off foreign matter adhering to the strip conductor with the cleaner belt and rotate the cleaner belt with a belt roller. This prevents foreign matter from concentrating in one place and from being scratched by the foreign matter, and by installing a foreign matter suction device on the side opposite to the position where the belt retainer is installed, the foreign matter adhering to the cleaner belt can be absorbed. , Keep the cleaner belt immediately before contacting the strip conductor Since the foreign matter removal function can be stably maintained for a long period of time, there is no risk of foreign matter entering the strip coil or damaging the strip conductor, and the reliability of the strip coil and, by extension, the mold transformer in which this strip coil is adopted. The effect of contributing to the improvement of the property is obtained.
