Description of the Related Art As a means for welding a thermoplastic resin film, heating means such as a hot plate seal, an impulse seal, a high frequency welder, an ultrasonic seal, a hot air seal, and a hot core seal are used. However, when it is necessary to perform an intermittent seal in which the seal portion and the non-seal portion are alternately mixed, instead of entirely applying the seal portion, the thermoplastic resin is not necessarily used. Not all film welding means are applicable. That is, among the welding means of the thermoplastic resin film, the heating means such as the hot plate seal, the high frequency welder, and the impulse seal are often apt to accumulate heat, which causes an abnormal temperature rise locally. However, in some cases, the film may be damaged, such as when the film is perforated, which is not suitable for partial heating. Further, heating means such as an ultrasonic seal, a hot air seal, and a hot-coating seal cause less damage to the film than the above-mentioned heating means and are excellent in terms of heat shrinkage, but The appearance after heat sealing of the sonic seal is most preferable. A conventional method of intermittently sealing a thermoplastic film using these heating means is to intermittently insert a heat source at the seal interface, or to perform a physical vertical movement of the heat source. However, the operation was extremely complicated.

An object of the present invention is to provide a method for intermittently welding a thermoplastic film by ultrasonic heating means.

Based on the signal, the welding means is intermittently operated so as to cause heat generation welding when the ultrasonic oscillation is turned on and non-welding when the ultrasonic oscillation is turned off. This is an intermittent heat welding method for a sheet, which is characterized by heat-welding a weldable adherend.

An ON-OFF oscillation signal is generated by some method such as a sequence or a combination of a timing cam and a limit switch, and this is sent to an ultrasonic oscillator, thereby operating the welding apparatus. Thus, intermittent welding can be easily performed without performing a troublesome operation such as intermittently inserting a heat source into the seal interface or physically moving the heat source up and down.

[FIG. 3] is an explanatory view of an apparatus for explaining the present invention. The thermoplastic resin sheets 2 and 2'which are adherends are fed from one side to the other side of the gap between the horn 1 and the welding roller-3.
The welding roller 3 presses the adherend against the horn 1 by means of a spring or the like. The horn 1 is connected to the ultrasonic wave oscillating device 4 and is sent from the ultrasonic wave oscillating device 4.
It vibrates by the N-OFF ultrasonic signal. The ON-OFF ultrasonic wave signal sent to the ultrasonic wave oscillating device 4 is generated by some oscillating means such as a crystal oscillator, a sequence, or a combination of a timing cam and a limit switch, and this is converted into an electric signal, for example. It is converted and transmitted to the ultrasonic oscillator. In such a device, the thermoplastic resin sheet 2, 2'which is the adherend vibrates intermittently by the horn 1 while it is in the gap between the horn 1 and the welding roller-3. Is applied to the adherend and vibration energy is intermittently applied to the adherend, and the thermoplastic resin sheet is welded by the welding roller.

Therefore, the size of the welded portions or the distance between the welded portions can be easily changed.

An ON-OFF signal generated by some kind of oscillating means is sent to an ultrasonic oscillator, and the thermoplastic synthetic resin sheet is intermittently welded by intermittently oscillating, and its operation is extremely simple. Especially, the welding time can be freely controlled by adjusting the ON-OFF signal.
With such an effect, the size of the welded portions, the distance between the welded portions, and the like can be easily changed. By this method, a sheet having a free intermittent welded portion can be easily manufactured.
