It is movably attached to.

The fitting portion 38 of the rotating member 30 is rotatably fitted in the mounting hole 29 of the adjusting member 28. The converter section 20 is fixed by being pressed from four directions by the eccentric cam 40 which is a holding means attached to the rotating member 30. A screw portion 46 is integrally formed with the eccentric cam 40, and the rotating member 30 is fixed by a bolt 42.
The screw portion 46 is inserted into the holding member 44 fixed to the. A driver slot 48 formed at the tip of the screw portion 46 is provided so as to be easily rotatable, and is fixedly attached by a nut 50. The adjusting member 28 includes a fitting portion 38 of the rotating member 30.

Next, the mounting position adjusting method of this embodiment will be described. First, the converter unit 20 of the ultrasonic welding device 10 is inserted into the rotating member 30 and the like, and the fixing members 54 and 5 are inserted.
The booster portion 22 is fixed to the mounting member 12 by 5.
Then, the eccentric cam 40 is rotated by a screwdriver or the like to be pressed against the side surface of the converter unit 20 so that the center C of the converter unit 20 substantially coincides with the virtual attachment center axis P of the ultrasonic welding device 10. Press and fix. Further, the anvil 18 is also mounted on the mounting member 12 and fixed so that its center coincides with the mounting central axis P. Thereafter, the rotating member 30 is rotated, and the rotating member 30 is stopped at the position where the parallelism between the facing portions of the horn 16 and the anvil 18 is maximized, and then the fixing screw 52 is tightened in that state. The rotating member 30 is fixed.

The principle by which the mounting position can be adjusted in this way will be described with reference to FIG. In the ultrasonic fusing apparatus 10 of this embodiment, substantially the central portion of the booster portion 22 is fixed by the fixing members 54 and 55, and the horn 16 is swung with reference to this fixing portion, and thus the anvil 18 and the anvil 18 are formed. The position should be set so that the facing parts of are exactly parallel. Therefore, the optimum position of the tip end surface of the horn 16 with respect to the anvil 18 is determined by moving the attachment position of the converter portion 20 which is another fixed portion. Here, assuming an actual mounting center C of the converter 20 and a rotating center axis R of the rotating member 30 with respect to an ideal mounting center axis P where the horn 16 and the anvil 18 face each other accurately, Converter centered on the dynamic center axis R
By rotating 0 by the rotating member 30, the center C of the converter 20 should be able to be located at the point K closest to the mounting center axis P. As a result, it is possible to adjust to an extremely small error KP with respect to the initial installation error δ of the converter 20.
Further, when the deviation ξ between the mounting center axis P and the rotating center axis R of the rotating member 30 is extremely small with respect to the error δ, no matter how much the rotating member 30 is rotated, the mounting center axis P and the converter 20 can be rotated. The error δ from the central axis C of does not become small. In this case, the rotating member 30 is rotated so that the direction in which the error δ occurs is approximately aligned with the direction of the key groove 32, and the adjusting screw 51 is rotated.
Thus, the adjusting member 28 is moved in parallel to move the central axis C of the converter 20 in parallel to the mounting central axis P to adjust the position. Further, when the position is adjusted more accurately after the above-mentioned adjustment, the fine adjustment is performed by the adjusting screw 51. still,
Here, the case where the mounting central axis P and the central axis C of the converter 20 coincide with each other has been described as the case where the horn 16 and the anvil 18 have the best parallelism. Since the positional relationship with the rotating member 30 is influenced, the rotating member 30 is observed while checking the parallelism between the horn 16 and the anvil 18 in the actual adjustment.
To rotate.

According to this embodiment, it is possible to accurately adjust the error of the mounting position only by rotating the rotating member 30, and it is possible to greatly reduce the number of steps required for the adjustment work. . Further, since the adjusting member 28 is provided so as to be movable in parallel and the converter 20 can also be moved linearly with the adjusting screw 51, an error that cannot be adjusted only by turning can be accurately fine-tuned by linear adjustment in one direction. It is possible.
