The new, slimline ULTRAPACK AMG ultrasonic generator from Herrmann Ultraschall with its innovative fieldbus concept fits perfectly into the slimline electrical control room of the coffee capsule packaging machine at Crailsheim-based packaging specialist Schubert.
In 48 stations, filter fleeces are welded into the capsule bases (ultrasonically clawed). The ultrasound is supplied by 24 generators, each of which supplies two oscillating structures. The new ULTRAPACK AMG with innovative cooling concept not only has an output of 1,200 watts, but also monitors and regulates the welding parameters independently. Integration into the machine control system via fieldbus interfaces enables the exchange of process data in real time.
Herrmann Ultraschall shows under the keyword „smart & connected“ In addition to the generator, the company will also present its transverse and longitudinal seaming modules and demonstrate the wide range of applications in the food industry. The focus is on the Coffee industry. In addition to filter materials, the lid foil can also be welded onto coffee capsules, and flavour valves and predetermined breaking points can be attached to bulk packs.
Bonding nonwovens with PP or PP with ultrasound
When combining typical packaging material made of PP or PE with so-called nonwoven materials, ultrasound can be used to create the desired bond quickly and reproducibly: for example, when sealing filter fleece, perforated films or filter papers in coffee capsules. At up to 250 degrees, the PET filter fleece has a higher melting point than the PP material of the capsule, which reacts more quickly to the ultrasound, becomes viscous and flows behind the PET.
