Abstract
Method and apparatus for filling bags wherein bags are filled one by one with a filling material and thereafter closed by means of an oscillating structure of an ultrasonic welding device. A parameter for the oscillating behavior of the oscillating structure is determined at no-load between closing two bags.
Claims11
A method for filling bags wherein bags are filled one by one with a filling material and thereafter closed by means of an oscillating structure of an ultrasonic welding device, wherein a parameter for the oscillating behavior of the oscillating structure is determined at no-load between closing two bags and wherein at least one checking device is provided for verifying if no bag is present, and wherein a measure of the oscillating behavior of the oscillating structure is determined during the filling of a bag.
A method for filling bags wherein bags are filled one by one with a filling material and thereafter closed by means of an oscillating structure of an ultrasonic welding device, wherein a parameter for the oscillating behavior of the oscillating structure is determined at no-load between closing two bags and wherein at least one checking device is provided for verifying if no bag is present, and wherein a measurement value for the oscillating behavior is derived by way of at least one electric measurement value, and wherein the measurement value for the oscillating behavior is derived from:
- a) the phase position at no-load;
- or
- b) the frequency at no-load;
- or
- c) the phase position and the frequency at no-load.
