Abstract

A filling device includes a first component and a second component. The first component includes a dosing cylinder having a high-viscosity material arranged therein. The second component includes a workpiece carrier and a receiving carrier. The receiving carrier is moveably connected to the workpiece carrier. The movement v of the receiving carrier during the filling process is determined by both the dynamic pressure exerted by the material and by a counterforce G generated by a unit having a pressurized fluid.

First claim

What is claimed is:

1. A device for filling in particular a high-viscosity material into filling containers, comprising:
a first component comprising a material container with at least one dispensing nozzle;
a second component comprising at least one carrier for receiving the filling containers, wherein the carrier is movably arranged relative to the first component through the dynamic pressure of the material generated during dispensing;
a unit having pressurized fluid for exerting a defined counterforce to the movement of the carrier caused by the dynamic pressure, wherein pressurized fluid from the unit for exerting the counterforce only results in the same movable arrangement of the carrier relative to the first component as the movable arrangement of the carrier relative to the first component through the dynamic pressure of the material generated during dispensing.

2. The device in accordance with claim 1 , wherein the device comprises two or more dispensing nozzles.

3. The device in accordance with claim 1 , wherein the unit for exerting the defined counterforce comprise at least one controller for open-loop control of the counterforce as a function of at least one parameter.

4. The device in accordance with claim 3 , wherein the unit comprises a measuring device for measuring the path travelled by the carrier from the start of the fill cycle.

5. The device in accordance with claim 4 , wherein the unit is a proportional pneumatic unit for setting the counterforce.

6. The device in accordance with claim 1 , wherein the device has a closed-loop control that regulates the dispensing pressure in the material container as a function of the fill time of the filling containers.

7. A method for filling particularly a high-viscosity material into filling containers, comprising:
a) exerting a dispensing pressure for purpose of dispensing the material from a material container into filling containers; and
b) moving of the filling containers under the dynamic pressure generated by the material flowing into the filling containers, wherein a defined counterforce is exerted against the movement of the filling containers, said movement being caused by the dynamic pressure during filling of the filling containers, wherein exertion of the counterforce only results in movement of the filling containers being the same movement of the filling containers under the dynamic pressure generated by the material flowing into the filling containers during dispensing of the material.

8. The method in accordance with claim 7 , wherein the material is dispensed through several dispensing nozzles in parallel.

9. The method in accordance with claim 7 , wherein the counterforce in step b) is open-loop or closed-loop controlled as a function of a measurement parameter.

10. The method in accordance with claim 9 , wherein the counterforce in step b) is open-loop or closed-loop controlled as a function of the path travelled by the filling containers during the filling process.

11. The method in accordance with claim 10 , wherein a maximum path travelled by the filling containers during the filling process is pre-set.

12. The method in accordance with claim 11 , wherein the speed of the filling containers during the filling process is determined by the dynamic pressure and the exerted counterforce.

13. The method in accordance with claim 12 , wherein the dispensing pressure is closed-loop controlled as a function of the dispensing time during filling of the filling containers between two different fill cycles.

14. A device for filling in particular a high-viscosity material into filling containers, comprising:
a first component having a material container with at least one dispensing nozzle;
a second component having at least one carrier for receiving the filling containers, wherein the carrier is movably arranged relative to the first component through the dynamic pressure of the material generated during dispensing; further wherein a defined counterforce is exerted by a unit having pressurized fluid to the movement of the carrier caused by the dynamic pressure, wherein exertion of the counterforce by the pressurized fluid of the unit only results in the same movable arrangement of the carrier relative to the first component as the movable arrangement of the carrier relative to the first component through the dynamic pressure of the material generated during dispensing,
at least one controller for open-loop control of the counterforce as a function of at least one parameter, and
a measuring device for measuring the path travelled by the carrier from the start of the fill cycle.

15. The device of claim 14 , wherein the unit is a proportional pneumatic unit for setting the counterforce.

16. The device of claim 15 , wherein the device has a closed-loop control that regulates the dispensing pressure in the material container as a function of the fill time of the filling containers.

17. The device of claim 16 , wherein the device comprises two or more dispensing nozzles.
