【考案の詳細な説明】 ［産業上の利用分野］ 本考案は、熱可塑性樹脂よりなる重合シート状被加工物
等を連続的に溶着する超音波溶着機に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an ultrasonic welding machine for continuously welding a polymerized sheet-shaped workpiece or the like made of a thermoplastic resin.

［従来技術］ 従来、この種の超音波加工機は加工用ホーンが被加工物
に対して直角方向に超音波振動し、その振動方向と平行
な軸線の周りに回転するようにされ、前記加工用ホーン

被加工物の送りを滑かにするために加工用ホーンと被加
工物の間に摩擦係数の小さな耐熱フィルム等を介在する
方法が提案されている。[Prior Art] Conventionally, in this type of ultrasonic processing machine, a processing horn ultrasonically vibrates in a direction perpendicular to a workpiece and is rotated around an axis parallel to the vibration direction. The pressure roller is arranged so as to be orthogonal to the center of rotation of the machined surface of the working horn in the radial direction, and at the same speed as the pressure roller on the feed side of the pressing roller for the purpose of improving straightness. It is composed of a feed roller that rotates in the same direction. Also,
A method has been proposed in which a heat-resistant film having a small coefficient of friction is interposed between the processing horn and the workpiece in order to smoothly feed the workpiece.

加工物の縁部から外れてしまうという問題点があった。[Problems to be solved by the invention] However, in such a method, since the rotation speed of the processing horn on the processing surface is largely different between the outer circumference and the inner circumference, processing with a narrow welding width or a work piece with a small friction resistance is performed. However, the welding width is wide, and wrinkles and wrinkles on the work piece due to the speed difference occur on the work piece with large friction resistance, and the friction resistance decreases due to the ultrasonic vibration action. There is a problem that the work piece is easy to move, and particularly when the work piece is welded along the edge part of the work piece, the pressure roller is disengaged from the edge part of the work piece.

本考案は、上述した問題点を解決するためになされたも

工物のずれを防ぐことによる作業性の向上にある。The present invention has been made in order to solve the above-mentioned problems, and a first object of the present invention is to provide a work piece that is polymerized by providing a pressing roller for temporary welding just before a pressure roller for welding. By integrating before welding, the wrinkles and twists of the work piece are minimized. The second purpose is to improve workability by preventing deviation of the work piece.

ローラを備えている。[Means for Solving the Problems] In order to achieve this object, the ultrasonic processing machine of the present invention is provided with a pressing roller for temporary welding on the workpiece feeding side of the pressure roller.

［作用］ 上記の構成を有する本考案は、重合シート状被加工物等

After the solidification, main welding is performed with a pressure roller.
