Abstract

A system and method of micro dosing containers on a conveying system is disclosed. The system includes a supply tank to maintain suspended solids in a mixture; a dosing assembly to inject micro-doses of the mixture into bottles; a recirculation assembly to circulate the mixture from the supply tank to the dosing assembly and back to the supply tank; a power and controls operation assembly to supply the system with power, to provide the system with electromechanical control and/or to provide a user interface; and a stand to hold at least the supply tank, the portable dosing assembly, the recirculation assembly and/or the power and/or controls operation assembly.

First claim

We claim:

1. A system comprising:
a supply tank for holding a homogenous micro dose blend suspension;
a sensor that detects a position of a pre-filled vessel;
a dosing assembly comprising a dosing pump that injects the suspension into a pre-filled vessel after the sensor detects the position of the pre-filled vessel;
a recirculation assembly that can circulate the suspension from the supply tank to the dosing pump and back to the supply tank using the sensor that detects the position of the pre-filled vessel, the recirculation assembly being fluidly coupled to the supply tank and the dosing assembly;
a power and controls operation assembly to supply the system with power, to provide the system with electromechanical control and to provide a user interface; and
a dosing stand to hold the supply tank, the dosing assembly, the recirculation assembly and the power and controls operation assembly.

2. The system of claim 1 , wherein the dosing stand is portable and comprises at least two wheels for tilt and two legs for securing the dosing stand in a working position.

3. The system of claim 1 , wherein the dosing stand comprises a hose rack for securing an umbilical bundle.

4. The system of claim 1 , wherein the supply tank comprises an agitator that mixes the suspension, wherein the agitator keeps the micro dose blend in suspension.

5. The system of claim 4 , wherein the agitator comprises a variable-frequency drive motor for controlling the rotational speed of the agitator.

6. The system of claim 1 , wherein the supply tank comprises a hinged lid for adding the suspension and cleaning.

7. The system of claim 6 , wherein the hinged lid comprises at least three sealed ports comprising a discharge outlet, a return inlet, and a filtered vent.

8. The system of claim 1 , wherein the recirculation assembly comprises a peristaltic pump for drawing the suspension from the supply tank and pumping the suspension to the dosing assembly.

9. The system of claim 8 , wherein the peristaltic pump comprises a variable-frequency drive motor for controlling the rotational speed of the peristaltic pump.

10. The system of claim 1 , wherein the recirculation assembly comprises an umbilical bundle for fluid and wiring transport.

11. The system of claim 10 , wherein the umbilical bundle comprises:
a dose supply tube fluidly coupled to the supply tank and the dosing assembly, wherein the dose supply tube supplies the suspension from the supply tank to the dosing assembly;
a dose return tube fluidly coupled to the dosing assembly and the supply tank, wherein the dose return tube returns the suspension that is not injected into the pre-filled vessel from the dosing assembly to the supply tank; and
a bottle sensor cable for automating an electromechanical control of the sensor.

12. The system of claim 1 , wherein the dosing assembly comprises a mobile stand for holding the pre-filled vessel.

13. The system of claim 1 , wherein the dosing pump is positioned on a support stand coupled to the dosing stand.

14. The system of claim 1 , wherein the dosing pump further comprises a servo controller to inject a desired amount of suspension into the pre-filled vessel by controlling one or more of a position and a speed of the dosing pump.

15. The system of claim 1 , wherein the sensor comprises a bottle sensor photo eye for detecting an opening of the pre-filled vessel.

16. The system of claim 1 , wherein the power and controls operation assembly comprises a power supply.

17. The system of claim 1 , wherein the power and controls operation assembly comprises a compact logic programmable logic controller for providing the system with electromechanical control.

18. The system of claim 1 , wherein the power and controls operation assembly comprises a human-machine interface (HMI) control panel for providing a user interface.

19. The system of claim 18 , wherein the HMI control panel comprises an operating and monitoring screen for user-controlled operation and monitoring.
