As an example of a sheet having a frame welded thereto, as shown in FIG. 6, a cosmetic such as a paste-like cosmetic 12 contained in a main body 11 of a compact container is always used in an appropriate amount. An adjustment filter provided so as to cover the upper surface of 12 can be exemplified. This filter for adjustment has a structure in which the peripheral end of the mesh sheet 1 is welded to the frame 2, and the cosmetic 12 is puffed through the mesh sheet 1.

びアンビル４で前記調整用フィルタを製造してみた。In an ultrasonic welding apparatus required for manufacturing such an adjustment filter, a horn and an anvil must be formed in accordance with a welding portion of the adjustment filter to be welded. In this case, as shown in FIG. As described above, the anvil 4 is formed in a flat plate shape, and the horn 3 is formed in a cylindrical shape corresponding to the frame 2, and the pressing surface S of the front end pressing portion 3a is formed as a plane parallel to the peripheral end surface of the sheet 1. Normally, the pressing surface S is vertically pressed and contacted with the peripheral end of the sheet 1 from directly above and ultrasonically welded, and the inventor of the present application manufactures the adjustment filter using the horn 3 and the anvil 4 described above. I tried to.

題点が生じた。However, when an adjustment filter was manufactured using such a horn 3 and an anvil 4, as shown in FIG. 7, the sheet 1 was entirely raised or depressed at the center of the frame 2 as shown in FIG. As a result, there arises a problem that the original function as described above cannot be obtained as an adjustment filter.
本発明は、このような問題点に鑑みなされたものであ
り、枠体にシートを緊張した状態で張設できる超音波溶
着用金型及びその金型を用いた超音波溶着方法の提供を
目的としている。The present invention has been made in view of such problems, and an object of the present invention is to provide an ultrasonic welding mold that can stretch a sheet to a frame body in a tensioned state and an ultrasonic welding method using the mold. And
本発明は、かかる従来の問題点を解決するために次な
る構成とした。The present invention has the following configuration in order to solve such a conventional problem.

では前記シート１に対して相対摺動不能であり、また、
前記枠体２は伸縮性を有する材料で形成され、枠体２と
この枠体２に接する前記相手方の金型とが相対摺動可能
であるものとした。That is, first, in an ultrasonic welding mold in which the sheet 1 is welded by overlapping the sheet 1 on the frame 2 and sandwiching the sheet 1 with a counterpart mold to be opposed, the ultrasonic welding mold corresponds to the shape of the frame 2. The pressing portion is formed in an annular shape, and the pressing portion S is provided with a pressing surface S which is inclined in a direction away from the other mold as it proceeds radially inward, and presses the sheet 1 and the frame 2. In the state, it cannot slide relative to the sheet 1, and
The frame 2 is formed of a material having elasticity, and the frame 2 and the opposite mold in contact with the frame 2 are relatively slidable.
ここで、超音波溶着用金型としては、ホーン３及びア
ンビル４と称される２種類のものがあり、これらが超音
波溶着装置において金型対を形成する。よって、本発明
において、相手方の金型がアンビル４である場合には、
本発明の金型はホーン３であり、相手方の金型がホーン
３である場合には、本発明の金型はアンビル４である。
そして、本発明が実施される場合、ホーン３の挾圧部3a
に挾圧面Ｓを形成するのがより好適である。Here, there are two types of ultrasonic welding molds called a horn 3 and an anvil 4, and these form a mold pair in the ultrasonic welding apparatus. Therefore, in the present invention, when the mold of the other party is the anvil 4,
The mold of the present invention is the horn 3, and when the counterpart mold is the horn 3, the mold of the present invention is the anvil 4.
When the present invention is carried out, the pressing portion 3a of the horn 3 is used.
It is more preferable to form the clamping surface S on the surface.
なお、挾圧面Ｓとしては、傾斜した曲面で形成される
場合も含む。The clamping surface S includes a case where the clamping surface S is formed by an inclined curved surface.
また、第２に、挾圧部（3aまたは4a）の全体に傾斜し
た挾圧面Ｓを形成するのではなく、挾圧部（3aまたは4
a）に環状突起５を設け、この環状突起５の内面を傾斜
した挾圧面Ｓとして形成する。Second, instead of forming an inclined clamping surface S over the entire clamping portion (3a or 4a), the clamping portion (3a or 4a) is not formed.
The annular projection 5 is provided in a), and the inner surface of the annular projection 5 is formed as an inclined pressing surface S.
この第２の金型においても、超音波溶着装置のホーン
３である場合と、アンビル４である場合との２種類ある
のは、第１の金型の場合と同様である。Also in this second mold, there are two types, that is, the case of the horn 3 of the ultrasonic welding device and the case of the anvil 4, as in the case of the first mold.
また、この第２の金型を使用して枠体２にシート１を

径を前記傾斜した挾圧面Ｓの外側周端縁の径より小さく
して、その内側段部6aが前記挾圧面Ｓに対向するように
しておく。When the sheet 1 is welded to the frame 2 using the second mold, an annular groove 6 is formed in the frame 2 in correspondence with the annular projection 5 of the mold. The inner diameter of the annular groove 6 of the body is made smaller than the diameter of the outer peripheral edge of the inclined pressing surface S so that the inner step 6a faces the pressing surface S.
そして、いずれの金型の場合でも、枠体２を相手方の
金型側にしてこの枠体２にシート１を重ね、前記相手方
の金型と前記超音波溶着用金型とで挾圧して、超音波振
動により枠体２にシート１を張り付ける。In any case, the sheet 1 is placed on the frame 2 with the frame 2 facing the other mold, and the sheet is sandwiched between the other mold and the ultrasonic welding mold. The sheet 1 is attached to the frame 2 by ultrasonic vibration.
〔作用〕 まず、第１の金型を使用した場合の作用について説明

下動自在に設置されているものとする。[Operation] First, the operation when the first mold is used will be described. For the sake of simplicity, in each of the following embodiments, the mold according to the invention is the horn 3 and the other mold is used. The description will be made assuming that the type is the anvil 4. Here, it is assumed that the anvil 4 is fixedly installed below and the horn 3 is installed so as to be movable up and down.
アンビル４上に枠体２を載置し、枠体２にシート１を

に傾斜させた挾圧面Ｓを設けてあるので、押圧力Ｐは第
２図に示すようにシート１と枠体２に垂直な垂直分力P1
とホーンの内方へと向かう水平分力P2とに分けられ、こ
れら各分力がシート１と枠体２とに作用する。The frame 2 is placed on the anvil 4, the sheet 1 is placed on the frame 2, the horn 3 is lowered, and the horn 3 and the anvil 4 sandwich the frame 2 and the sheet 1. Here, since the pressing portion 3a of the horn 3 is provided with a pressing surface S which is inclined inward in a direction away from the anvil 4, the pressing force P is applied to the seat 1 and the frame as shown in FIG. Vertical component P1 perpendicular to 2
And is divided into a horizontal force P 2 towards the inside of the horn, each of these component forces acting on the seat 1 and the frame 2.
ここで、挾圧面Ｓとシート１との間に摩擦がなけれ
ば、シート１と枠体２とは前記水平分力P2によりいずれ
も内方へと押し縮められるが、挾圧面Ｓとシート１との
間に摩擦力が生ずるため、シート１は挾圧面Ｓに一体に
保持されたままとなる。Here, if there is no friction between the挾圧surface S and the sheet 1, although the sheet 1 and the frame 2 is shortened press both inwardly by the horizontal component force P 2,挾圧surface S and the sheet 1 , A frictional force is generated between the sheet 1 and the sheet 1, so that the sheet 1 remains held integrally on the pressing surface S.
一方、シート１と枠体２との接触部分では超音波振動
による摩擦熱で両者が溶融し、いわば潤滑剤が介在した
状態となっているため、シート１と枠体２との間の摩擦

て、ホーン３による押圧を解除すると、枠体２が元の状
態に広がるので、シート１は外側に向かって均等に引っ
張られ、シート１が枠体２に緊張して平坦に張設され
る。On the other hand, in the contact portion between the sheet 1 and the frame 2, the two are melted by frictional heat due to the ultrasonic vibration and the lubricant is interposed, so that the frictional force between the sheet 1 and the frame 2 is increased. is small, only the frame body 2 by the horizontal component force P 2 is contracted inwardly, the sheet 1 is welded to the frame body 2 in this state. Therefore, when the pressing by the horn 3 is released, the frame 2 spreads to its original state, so that the sheet 1 is evenly pulled outward, and the sheet 1 is tensioned to the frame 2 and stretched flat.
なお、溶着すべきシート１は予め枠体２の大きさに裁

裁断されるようにしてもよい。The sheet 1 to be welded may be cut into the size of the frame 2 and then welded. However, one large sheet 1 is welded to the frame 2 and then the size of the frame 2 is reduced. The sheet may be cut into pieces. For this purpose, a cutter may be attached to the horn 3 so that the sheet 1 is cut at the same time as the horn 3 is pressed.
次に、第２の金型を使用して溶着する場合の作用につ
