Ultrasonic welding device and ultrasonic welding method for controlling continuous ultrasonic welding processes

Ultrasonic processing method of an ultrasonic processing device, comprising:

• an ultrasonic generator, a converter and at least one sonotrode with an oppositely arranged counter tool, which are spaced from each other by a gap, wherein the sonotrode or the counter tool is arranged rotatably and comprises an even or an uneven circumferential surface, a controlling/regulating module integrated in a signal processing of the ultrasonic generator so that with respect to the ultrasonic generator a plurality of generator data is processible in the ultrasonic generator, especially an electric voltage U, an electric current I, an actual amplitude Aist and/or an actual generator power Pist, wherein the ultrasonic processing method comprises the following steps:
• a. determining an angular speed (step I) of the rotatably arranged counter tool or the rotatably arranged sonotrode,
• b. detecting (step II) at least one data set of the plurality of generator data,
• c. comparing a power actual value Pist with a power reference value Psoll of the ultrasonic generator in a gap regulator and specifying a position reference value POSsoll of the sonotrode with respect to the counter tool and/or
• d. comparing a power actual value Pist with a power reference value Psoll of the ultrasonic generator and specifying an amplitude reference value in the ultrasonic generator for adjusting the power reference value Psoll of the ultrasonic generator.
