Filling device

A filling device for dosing a defined amount of loose-type material, comprising:

• a filling unit with a basic body rotating symmetrically around an axis of rotation;
• and
• a control device having two controlling arms,
• wherein the basic body has, passing through it, at least one inlet section extending in the axial direction of the axis of rotation, a dosing channel section having a defined volume and a dosing channel comprising an outlet section,
• wherein the dosing channel has a dosing channel section inlet and a dosing channel section outlet,
• wherein the basic body comprises at a first end a first intake unit for a storage receptacle for loose-type material arranged on the filling unit and at an end opposite the first end, a second intake unit for an intake receptacle for loose-type material arranged on the filling unit,
• wherein the basic body possesses two controlling arm guides for accommodating the controlling arms displaceable in the controlling arm guides of the controlling device, wherein a first controlling arm of the two controlling arms has a dosing channel section inlet opening associated with the dosing channel section inlet and a second controlling arm of the two controlling arms has a dosing channel section outlet opening associated with the dosing channel section outlet,
• wherein the control device can be selectively brought into different shift positions by displacement, wherein the shift position is an inlet position in which, when the control device is brought there, the dosing channel section inlet opening releases the dosing channel section inlet associated with it to fill the dosing channel, and at the same time, the dosing channel section outlet is closed, and wherein the shift position is an outlet position in which, when the control device is brought there, the dosing channel section inlet is closed and at the same time the dosing channel section outlet opening releases the dosing channel section outlet associated with it,
• wherein the basic body is formed in several parts, wherein the basic body has a dosing channel body rotatable around the axis of rotation, the body possessing a plurality of dosing channel sections with different defined volumes, and
• wherein each of the plurality of dosing channel sections with different defined volumes can be locked in the dosing channel of the basic body by rotation around the axis of rotation,
• wherein the filling device further comprises an energy storing device in the form of a spring arranged between the basic body and the control device that provides a common biasing force to the first controlling arm and the second controlling arm, and
• wherein the first controlling arm and the second controlling arm move in synchronization with one another between the different shift positions by displacement of the energy storing device.
