Definitions
- the present invention relates to an apparatus and a method for welding and separating packaging materials for packaging with a combined ultrasonic welding apparatus and cutting apparatus, which is used in particular in tubular bag machines.
- an elongated closed tube is usually produced from a film via a forming shoulder, one end of which is sealed by means of an ultrasonic welding device comprising a sonotrode and an anvil by a transverse sealing seam.
- the packaging material is welded between the sonotrode and the anvil by touching the two parts. After filling, the tube is then over the filling area by a further transverse sealing seam to a

- the device for this purpose has an ultrasonic welding device with a sonotrode and an anvil for sealing the packaging material, wherein the sonotrode is rotatable about a first axis of rotation and the anvil is rotatable about a second axis of rotation.
- the device has a cutting device with at least one knife for separating the packaging material, which is arranged in the anvil.
- the at least one knife is arranged on the anvil such that a
- the device also comprises an adjusting device which adjusts the position of the knife in the anvil in the radial direction of the anvil.
- the blade position can be easily adapted to the oscillation amplitude of the sonotrode in accordance with the packaging material to be separated.
- changeover times of the device are substantially reduced, which contributes to increased cost efficiency of the production.
- the knife has an additional cutting edge to a
- the knife is only slightly, in particular by 5 ⁇ to 50 ⁇ , preferably 10 .mu.m to 20 ⁇ , from one of the sonotrode facing surface of the anvil ago.
- the knife can introduce the packaging material by this amount to the sonotrode, the high-frequency vibration of the packaging material at the cutting edge of the knife without a contact force between
- an anvil surface of the sonotrode is planar and without
- the knife is fixedly mounted in the cutting device.
- an elastic element between the blade and the anvil for vibration decoupling between sonotrode and anvil can be omitted, which contributes to the further simplification and cost reduction of the device. It also simplifies the replacement and adjustment of the knife.
- the cutting device is preferably between a first
- the invention relates to a method for welding and separating a
- a reliable sealing and contactless and wear-free separation of the packaging material according to the invention is achieved in that positioned in a first process step of the packaging material between a sonotrode and an anvil of an ultrasonic welding device and a bottom seam of a preceding pack is sealed. Subsequently, the
- the sonotrode vibrates the packaging material so that the packaging material is severed by the knife. It is in each position of
- a cutting force of the cutting device is smaller than a sealing force of the ultrasonic welding device. This contributes to an improved seal quality of the head and foot seams of the packages.
- the knife is preferably adjustable, so that the size of the minimum distance to the
- Vibration amplitude of the sonotrode and can be adjusted and adjusted according to the material thickness and material properties of the packaging material. Short description of the drawing
- Figure 1 is a schematic sectional view of the invention
- Figure 2 is a schematic sectional view of the device of FIG.
- Figure 3 is a schematic sectional view of the device of FIG.
- Figure 4 is an enlarged schematic sectional view of
- the device 1 for welding and separating a packaging material 4 comprises an ultrasonic welding device 2 with a sonotrode 3 and an anvil 5, between which the packaging material 4 forming a preceding package 14 and a subsequent package 15 a direction indicated by an arrow conveying direction F is passed.
- the sonotrode 3 is rotatable about a first axis of rotation X and the anvil 5 is rotatable about a second axis of rotation Y.
- a cutting device 6 is arranged with a knife 7 and an adjusting device 9, by means of which the knife 7 is fixed and set in the radial direction of the anvil 5.
- the cutting device 6 is arranged between a first sealing area 12 and a second sealing area 13 of the anvil 5.
- the knife 7 is facing one of the sonotrode 3
- a minimum distance S between a cutting edge 8 of the blade 7 and a roof point 20 of the sonotrode 3 is maintained at a maximum deflection of the sonotrode 3, which is symbolized by a dashed line.
- This minimum distance S is preferably in a range of 5 ⁇ to 50 ⁇ .
- FIGS. 1 to 3 The welding and separating of the packaging material 4 of a packaging takes place in three steps or positions, which are illustrated in FIGS. 1 to 3.
- first a foot seam 16 of the preceding package 14 is attached to the first
- Sonotrode 3 a rotation about its axis of rotation X in the direction of an arrow P1 and the anvil 5 a rotation about its axis of rotation Y in the direction of an arrow P2 according to the example shown in Figure 4 each of 8 °.
- Rotation of the anvil 5 is raised or guided by the knife 7 in the direction of the sonotrode 3 and rests on the cutting edge 8.
- the packaging material 4 is severed between the roof point 20 and the cutting edge 8 of the knife, wherein the minimum distance S is set to be smaller or at most equal to a material thickness of the packaging material, so that no mechanical contact between the sonotrode 3 and the knife 7 he follows.
- a top seam 17 of a subsequent package 15 is sealed on the second sealing area 13.
- the sonotrode 3 and the anvil 5 each perform a further rotation of 8 ° about their axis of rotation X or Y in the direction of arrow P1 or P2 and seal between the sonotrode 3 and the anvil 5, the top seam 17 of the subsequent package 15th
- the device according to the invention can be used on conventional rotary
- Tubular bag machines can be used or retrofitted and allows the contact-free and wear-free separation of the packaging material with minimal cutting forces, which are lower than the sealing forces for producing the head and foot seams. Due to the minimal rotational movements of the ultrasound Sealing tools are very short work record and a correspondingly high production throughput achievable.
