木兄、明はプラスチックの超音波溶着力法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION Kinoe and Akira are concerned with the ultrasonic welding force method for plastics.
従来の超音波溶着方法は筒知のように、重ね合わせた級
浴着プラスチックに対して、重ね合わせWIK対して片

ど一組、即ち2個を浴着する場合が多く、捷れに薄噛・
ノート状の場合、3個以上の浴着が行なわれてきた。The conventional ultrasonic welding method, as in Tsutsuchi, was to apply ultrasonic vibration energy and static pressure to the stacked WIK from one edge of the stacked WIK. If we look at the details more closely, we can see that most of the overlapping bath kimonos are worn in one set, that is, in many cases, two pieces, and they are loose, thin, and loose.
In the case of notebook-shaped yukata, three or more yukata have been used.

った。However, the welding means is the piece 11+ of the garment to be bathed.
111d was pressed against the base 7, and ultrasonic imaging energy was supplied from the counterpart 111i to bathe the overlapping surfaces. In the case of a thin sorted bath kimono, since the object to be welded is thin, it is necessary to use an ultrasonic energy supply method, for example, to make the bath kimono into a knurling shape. However, there were some difficulties with the finished shape.
最近のプラスチック溶着の応用分野は1111広がり、

り形状にも難かあった。Recently, the application fields of plastic welding have expanded by 1111.
Moreover, high precision and tube quality are required, and from this point of view, conventional methods are not satisfactory. The reason for this is due to the method of supplying ultrasonic vibration energy only on one side.
Unfortunately, the behavior of the welded material on the opposite side to the supply side is unstable. In other words, when it is the same, the bathed green object vibrates in phase IIη, or when it is the same, the ultrasonic wave is supplied 0111 and vibrates, and the other side is Ii'z+, or in the case of the same bathing kimono. However, there was some variation. There was also a tendency for interpolation when there was a thin sheet-like initial offset surface. There were also some difficulties with the finished shape.

良い。The present invention is constructed as described above, and both plastics /-/, /-2 to be welded are positively supplied with ultrasonic vibration energy from both sides and are also subjected to static pressure. Once L7 is reached, a phenomenon occurs in the overlapping surfaces of the plastics where they try to collide with each other, and that energy is definitely consumed by the overlapping surfaces, resulting in a mess. What is important here is that when the ultrasonic frequencies on both sides are the same, the phase of the vibration must be in-phase for efficient bathing. This is particularly effective when it comes to plastic dimensions. In other words, a correlation meter between the thickness direction dimension of the plastic to be welded and the ultrasonic frequency has an effect on the welding (7) and the groove. Therefore, it is better to use a high frequency for thin materials and a low frequency for thick materials. .
