Definitions
- the present invention relates to a method for joining a longitudinal seam of a flexible packaging, and more particularly to a method for joining a
- the present invention relates to a longitudinal seam joining device of a tubular bag machine for applying the method according to the invention.
- Tubular bag machines are produced by means of conventional ultrasound in the range of 20 to 40 kHz joint connections to packaging.
- Packaging material hose separated into individual tubular bags by cutting function.
- Conventional ultrasound systems exist in the known methods
- the heat generation in the packaging material is based on internal friction and
- the sound is introduced into the joining zone usually perpendicular to
- DT 1704204 A a method for joining plastic parts based on focused ultrasound is known.
- the ultrasonic waves generated by a vibrator with a frequency above 100 kHz are bundled by the vibrator geometry or a focusing device and transmitted through a liquid medium to the joint.
- the sound waves conducted through the liquid medium excite a diaphragm to vibrate, which is pressed onto the plastic parts to be welded.
- DE 10 2008 044 370 A1 describes a device and a method for connecting components by means of focused ultrasound.
- the waveguide is thereby either by a metallic solid material made cone-shaped element or formed from a liquid or gel-filled membrane.
- the present invention thus relates to a method for joining a
- Packing materials a frequency range of 0.1 MHz to 5 MHz, preferably from 0.5 MHz to 2 MHz used.

- the sound conductor is forming a progressive
- Wave field off A significant advantage is that the sound conductor does not have to be designed resonantly, quasi exist in terms of its design no restrictions, as is known from conventional ultrasound ago. This means that the effective surface of the ultrasonic application can be optimally adapted to the geometry to be joined, in this case the sealed seam. By given focusing devices (lens, geometry of the ultrasonic transducer), a focusing of the sound waves is achieved. The sound conductor is much more compact compared to the geometric extension of the conventional
- the ultrasound applicator can be fixed at any desired location.
- the attachment can be made very close to the joint, thus this variant shown is much stiffer than it is possible with an attachment in the node vibration.

- Vibration excitation occurs in the audible frequency range and the high frequencies in the air but also in the machine parts very quickly damped and do not spread over long distances.
- Conventional ultrasound systems oscillate after switching off the power supply for about 350 ms. This represents a potential danger spot for the operator, since even in the emergency stop case there is no immediate standstill of the vibrating structure.

- the ultrasonic energy is precisely introduced into the joint area. Due to the focusing devices (lens, geometry of the ceramic) a focusing of the sound waves is achieved.
- the sound conductor is thus much more compact compared to the geometric extent of the conventional sonotrode and is not put into resonance vibrations. This feature allows you to create smaller assemblies and significantly reduces manufacturing costs.
