Packaging machine and method for introducing bulk materials into containers

A method for filling bulk materials into packages by means of a packaging machine having a rotary machine frame and a plurality of filling spouts distributed over the circumference, so as to fill bulk materials into packages while the machine frame is rotating;

• wherein a machine silo is configured at the machine frame and has a storage volume for storing a quantity of bulk materials sufficient for filling a plurality of packages;
• wherein the machine silo fills bulk materials into the packages through the filling spout;
• wherein at least one material supply with a controlled closing member is attributed to the machine silo so as to feed bulk materials to the machine silo;
• and a control device controls a controller of the closing member of the material supply dependent on the fill level in the machine silo, to reduce the height of fall of the bulk materials while the bulk materials are being fed into the machine silo or to avoid a free fall of the bulk materials during the feeding of bulk materials into the machine silo in continuous operation;
• wherein a free cross section of a feed opening of the material supply is inversely proportional to the fill level.

A packaging machine for filling bulk materials into packages, comprising:

• a rotatable machine frame and a plurality of filling spouts distributed over the circumference so as to fill bulk materials into packages while the machine frame is rotating;
• wherein a machine silo is configured at the machine frame and has a storage volume for storing a quantity of bulk materials for filling a plurality of packages;
• wherein bulk materials can be filled into the associated packages from the machine silo through the filling spout;
• wherein the machine silo is connected with a material supply having a controllable closing member for feeding bulk materials to the machine silo;
• said machine silo is provided with at least one sensor for determining a fill level of bulk material in the silo;
• and
• a control device is provided with which to control at least one of the closing member of the material supply dependent on the fill level, reducing the height of fall of the bulk materials while the bulk materials are being fed to the machine silo, and avoiding a free fall of the bulk materials during the feeding of bulk materials into the machine silo in continuous operation;
• wherein the control device actively controls the position of the closing member as a function of a sensor signal of said at least one sensor, such that a varying amount of bulk material is supplied based on the position of the closing member.
