The second vibration generator generates vibrations of a higher frequency compared to the first vibration generator.

Abstract: Packing unit (1) with a packing machine (2) for filling bulk materials (3) in open sacks with a sack suspension device (7), for suspending the open sacks at a filling nozzle (8-10) of a product supply device (11, 13) and filling the same with at least one bulk material. The sack suspension device is provided with at least two selectable product supply devices. The at least two product supply devices and the sack suspension device are movable relative to each other in order to select a product supply device and to suspend a sack by means of the sack suspension device at the filling nozzle of the selected product supply device and to fill bulk material in the open sack by means of the corresponding filling nozzle.

Abstract: Method and apparatus for filling bags with loose materials, wherein a package to be filled is filled by means of a filling element in a filling process. The filling process comprises a filling stage, a settling stage, and a discharge stage wherein during the filling stage, loose material is filled into the bag while admitting air and in the settling stage, a settling phase is provided for the pressure to drop and in the discharge stage, the bag is discharged from the filling element. In the settling phase, the squeezing device applies a squeezing pressure to the package so as to vent the package and to reduce the volume available to the package, until a predetermined reduction of the volume available to the package is reached, whereupon the squeezing pressure of the squeezing device on the package is reduced and the package is discharged from the filling element.
