Packaging fluidic goods (liquids or dry goods), the machine output is often limited by the spillage behaviour of the filling good. If filled but not yet closed containers are transported intermittently through the machine the filling good oscillates. In the most unfavourable situation this causes the good to pour over the container’s edge which leads to rejects and machine standstills.

The determination and use of suitable motion profiles considering the specific conditions such as rheological properties of the product and the container geometry is a possibility to reduce the maximum splash height and thereby to increase the productivity of the packaging machine. The optimisation of the container motion is important for improvement of existing packaging machines for liquids and dry goods and for the development of new ones.

The optimisation is carried out using numerical calculations (computing fluid dynamic, numerical optimisation using equivalent models). In addition, experimental studies on drive testing equipment are used to investigate practical conditions. The drive test equipment permits a free choice of motion profiles to verify the numerical calculations. For the evaluation of the product behaviour a high-speed-camera is used.

Aims of the research are:

  • development of a methodology for optimisation of the motion of containers with fluidic goods,
  • creation of a calculation programme depicting the vibrations of fluidic goods,
  • determination of the influence of essential parameters on the vibration behaviour and
  • definition of a procedure for the determination of the machine configuration
