摘要:
The invention relates to an apparatus for cutting a packaging material (4) for a package, comprising an ultrasonic welding device (2) that includes a sonotrode (3) and an anvil (5) for sealing the packaging material (4), the sonotrode (3) being rotatable about a first axis of rotation (X) and the anvil (5) being rotatable about a second axis of rotation (Y). The apparatus further comprises a cutting device (6) which includes at least one knife (7) for cutting the packaging material (4) and which is arranged within the anvil (5). The invention is characterized in that the knife (7) has a blade (8) with a cutting edge (28) that includes at least two tips (33, 35) and at least two curved sections (22) interconnecting the two tips (33, 35).
摘要:
A device and a method is proposed whereupon the device for processing a packing material using ultrasound comprises the following elements: at least one sonotrode (10), at least one anvil (12), whereupon a gap is constructed between sonotrode (10) and anvil (12) through which the packing material can be passed for the purpose of ultrasonically sealing a packing material, at least one adjustment means (50) that adjusts the gap (s) between sonotrode (10) and anvil (12), at least one generator (70) that changes an input voltage into an output voltage, which a converter (74) transforms into mechanical oscillations in order to generate ultrasonic oscillations on the sonotrode (10), whereupon a regulation device and/or control device (78) is arranged to regulate or control the gap (s) between sonotrode (10) and anvil (12) depending on at least one electric variable (P,E,R) that acts on the sonotrode (10).

The invention relates to an apparatus for welding and separating a packaging material (8), comprising an ultrasonic welding apparatus (2) having a sonotrode (3) with at least one sonotrode segment (3a), and an anvil (4) with at least one anvil segment (4a), and a combined cutting and tensioning device (5), wherein the sonotrode (3) can be rotated about a first rotational axis, and wherein the anvil (4) can be rotated about a second rotational axis. The cutting and tensioning device (5) is integrated in the ultrasonic welding apparatus (2), wherein initially, the cutting and tensioning device (5) tensions the fed packaging material (8), cutting it thereafter in a tensioned state with a blade (6).
