Electronic counting of sealing cycles of an ultrasonic sealing device in a packaging machine

摘要

Packaging Machine (1) operable to produce sealed packages (8) made of heat-seal sheet packaging material (3) and containing a food product, and comprising an ultrasonic sealing device (12) including an electrical power signal source (19) operable to generate an electrical power signal (V US ); an ultrasonic transducer (20) electrically coupled to the electrical power signal source (19) to receive the electrical power signal (V US ) and responsively heat seal the sheet packaging material (3); and an electronic counter (10) operable to count the ultrasonic sealing cycles of the ultrasonic sealing device (12).
