Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping device for winding a tape on a ring-shaped winding core in multiple layers.

[0002]

2. Description of the Related Art FIG. 7 shows a conventional taping device in which a tape is wound around a ring-shaped winding core in multiple layers. In the figure, 51 is a work that is a ring-shaped winding core, 52 is a holder that fixes both ends of the work 51, and 53 is the tape 50 that is rotated on the work 51 while rotating the tape 50 in and out of the work 51. A rotating ring around which the rotating ring 53 is rotatably supported, 55 is a tape reel attached to the rotating ring 53, and 56 is an elevating frame that holds the rotating frame 54 and moves up and down. Reference numerals 57 and 57 are front and rear moving frames for moving the elevating frame 56 up and down, 58 is a horizontal moving frame for moving the front and rear moving frame 57 in the front and rear direction, and 59 is a base for moving the horizontal moving frame in the left and right direction.

Next, the operation of this taping device will be described. The rotating ring 53 is set according to the taping start position of the work 51, and the winding start end of the tape 50 is bonded to the work 51. Subsequently, while rotating the rotating ring 53, the movements of the elevating frame 56, the forward / backward moving frame 57, and the lateral moving frame 58 are controlled to move the swinging frame 54 along the shape of the work 51, and the tape reel 55 For example, the work 51 while feeding the tape 50
Wrap the tape 50 in 1/2 overlap. Then, if taping work is performed up to the end of the work 51, taping work is similarly performed for the second layer, the third layer, ...
When the taping work is completed, the tape 50 is cut from the tape reel 55, and its end portion is bonded to the work 51.

[0004]

However, if taping is performed on the ring-shaped work 51 over a number of layers by the above-described conventional taping device, the taping layer of the tape 50 wound around the work 51 becomes thick. Since the diameters of the inner peripheral surface side and the outer peripheral surface side greatly differ, the degree of overlap of the tape 50 on the outer peripheral surface side and the inner peripheral surface side of the work 51 differs. Therefore, as shown in FIG. 8, the tape 50 is thicker on the inner peripheral surface side than on the outer peripheral surface side of the work 51.
However, there is a problem in that the uniformity of the thickness of the taping layer with respect to the work 51 is impaired.

For this reason, a patch patch tape is manually attached to the outer peripheral surface side of the work 51 along the axial direction of the work 51, and the tape 50 is automatically wound on the patch applying tape so that the inner and outer peripheries of the work 51 are Although the thickness of the tape layer between them has been equalized, there has been a problem in that the work of attaching the patch patch tape requires manpower, and a smooth and quick automatic winding operation of the tape 50 cannot be performed.

The present invention has been made to solve the above problems, and when the tape is automatically wound around the ring-shaped winding core at a predetermined pitch, the inner peripheral surface side and the outer peripheral surface of the core are wound. An object of the present invention is to provide a taping device capable of automatically achieving uniform thickness of the taping layer on the side.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a revolving frame for winding a main winding tape around a ring-shaped winding core is moved along the shape of the winding core while the main winding tape is wound around the winding core at a predetermined pitch. In a taping device for winding a tape, a patch applying tape reel for feeding the patch applying tape along the outer peripheral surface side of the core and a patch applying tape reel preceding the turning frame along the outer peripheral surface side of the core. And a moving means for moving the patch pad tape reel.

[0008]

The main winding tape can be automatically wound around this winding core at a predetermined pitch by moving the revolving frame around the ring winding core along the shape of the winding core. However, due to the difference in the overlapping state of the main winding tapes, the thickness of the taping layer on the outer peripheral surface side of the winding core with a large ring diameter becomes smaller than that on the inner peripheral surface side of the winding core with a small ring diameter. .

Therefore, in this taping device, the patch applying tape reel for feeding the patch applying tape along the outer peripheral surface side of the winding core is moved by the moving means along the outer peripheral surface side of the winding core prior to the turning frame. By doing so, the patching tape is preceded by the main winding tape, and the patching tape is wound around with the main winding tape to reduce the difference in the thickness of the taping layer between the inner peripheral surface side and the outer peripheral surface side of the winding core. Made it possible to resolve it automatically.
