Description of the Related Art A relatively small product, such as a battery, is wrapped in a single film or a plurality of films simultaneously and successively, cut into product units, and then packed by shrinking the film. It has taken root. As one example, a packaging process of a plurality of batteries is shown in FIG. (A) A predetermined number of batteries 1 are placed on one side of the film 2, (B) the other side of the film 2 is folded back, (C) the joined portion of the film 2 is welded, and unnecessary parts are cut and discarded ,
(D) The batteries in the tube-shaped film 2 'are cut off by a predetermined number, and (E) the film is shrunk to complete a packed product form.

As shown in FIG. 4, one example of the ultrasonic welder is an ultrasonic transmitter 12, a horn 13 for concentrating the energy of the ultrasonic wave at its tip, and a roller-type receiving device for pressing the film in cooperation with the horn. A jig 14 is provided to weld the film by frictional heat generated in the pinching portion by ultrasonic energy concentrated on the tip of the horn, and to blow and remove unnecessary portions of the film. At this time,
To reliably transfer the film between the vibrating horn tip and the nip, the roller-type receiving jig 14 includes a coil spring 17.

A problem that the The optimum clamping pressure cannot be neglected by the influence of room temperature, humidity, etc. in addition to the film material and the film pressure. recent years,
Due to environmental problems, the film material has been replaced with PET resin, and it has been required to finely adjust the clamping pressure. Depending on the coil spring, such adjustment of the optimal clamping pressure may be required. It's getting harder. The present invention seeks to provide an ultrasonic welder that can always maintain an optimum clamping pressure.

More specifically, as shown in FIGS. 1 and 2, a film 11 and a table 11 to which a battery 1 mounted thereon is transferred are provided, and an ultrasonic transmitter 12 is provided above the film. At the lower part of the horn 13, a roller type receiving jig 14 which opposes the horn and presses the film 2 in cooperation with the horn is provided. These horns and receiving jigs are made of high strength metal such as cemented carbide. The roller-type receiving jig 14 is rotationally driven by a motor (not shown) in synchronization with the film feed speed, and is pressed against the horn 13 by the air pressure of the air cylinder 15.
