Description

  The present invention relates to a taping device, and more particularly to a taping device for winding an insulating tape around a coil of an electric motor or a generator.

  In the conventional taping device, a coil is placed at the center of a rotating ring, which is a taping head, around a linear portion in the coil of an electric motor or a generator and the vicinity thereof, and an insulating tape is wound thereon. It is intended for extremely narrow spaces such as coil ends, curved parts, and coils that are smaller than the rotating ring. When winding the coil eccentrically from the center of the rotating ring, or when the coil cross section is rectangular and the long side is short When the difference between the sides is large, the tension of the insulating tape is greatly changed, and the insulating tape is stretched or loosened, resulting in problems of insulation quality and inability to wind.

  In order to solve this problem, the tension of the tape is generated by the friction with respect to the rotation of the tape reel, and the elongation and looseness of the tape caused by the winding position of the taping head with respect to the coil is adjusted by the rotation of the link. The rotational force of the link is transmitted to the tape reel, and the tape tension is automatically adjusted (for example, Patent Document 1).

Japanese Patent Laid-Open No. 9-77388

However, in such a taping device, the adjustment allowance for fluctuations such as tape expansion and looseness is determined by the length and rotation angle of the link. When taping the coil, it is difficult to place the coil to be wound in the vicinity of the center of the rotating ring as the taping head, and when the coil is placed eccentric from the vicinity of the center of the rotating ring, the difference in aspect ratio is large. In the case of a coil, since the amount of fluctuation such as elongation or looseness of the tape becomes large, it is necessary to enlarge the link in accordance with the amount of fluctuation, which increases the size of the rotating ring and the rotational load.
Conversely, if the taping head is downsized, the adjustment allowance for the amount of tape fluctuation decreases, and depending on the positional relationship between the coil and the rotating ring, the adjustment allowance cannot follow the amount of tape change. There were issues such as being unable to do so.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a taping device having a simple configuration capable of accurately adjusting the amount of fluctuation such as elongation or looseness of a tape. It is said.

  A taping device according to the present invention includes a rotary member having an opening for inserting a taped material to be rotatably supported on a taping base for winding a tape around the taped material, and a rotation for rotating the rotary member. Means, a tape supply means for supplying the tape from the taping substrate side, a brake belt member for pressing the tape supplied from the tape supply means to the peripheral surface of the rotating member that circulates around the taped material, and the rotation The apparatus comprises unwinding roller means for unwinding the tape from the member onto the taped material, and belt driving means for driving the brake belt member.

  According to the present invention, it is possible to obtain a taping device having a simple configuration capable of accurately adjusting the amount of fluctuation such as elongation or looseness of the tape.

Rotating ring 1, motor 7 that rotationally drives rotating ring 1, two driving rollers 10, connecting shaft 15 that simultaneously operates two driving rollers 10, control unit 20 that detects torque of motor 7, and rotation A bearing 5 that guides the rotation of the ring 1, a brake belt 8 that feeds the insulating tape 4 from the tape reel 3, a motor 14 that drives the brake belt 8 to adjust the feed amount, a guide 13 for the brake belt 8, a brake A tension spring 11 and a tension roller 9 for tensioning the belt 8 and tensioning the insulating tape 4; A roller 6 unwinding edge tape, and a frame 12 that each part is Toritsui.

The frame 12 as a taping substrate is for winding the insulating tape 8 around the coil conductor 2 as the taped material, and forms a pair having an opening 12p for inserting the coil conductor 2 as the taped material. The disk-shaped frame member 12a and the frame member 12b are configured to rotate counterclockwise in FIG. 1 about a rotation center RC eccentric from the coil conductor 2.
The insulating tape 4 supplied from the tape reel 3 attached to the frame 12 composed of the frame member 12a and the frame member 12b is driven by a motor 14 and guided by a guide roller 13 by a brake belt 8 and then the frame member 12a and the frame member. A groove provided with a U-shaped cross section provided on the peripheral surface 1a of the rotating ring 1 rotatably supported around a rotation center RC eccentric from the coil conductor 2 by a bearing 5 attached to a frame 12 made of 12b.
