Abstract

A system having a material sensor system coupled to a material tank is provided. The material tank is configured to receive a quantity of the material and output a flow of the material. The material sensor system includes a float system coupled to an inner surface of the material tank. The float system includes a float configured float within a float cavity. The material sensor system includes a switch coupled to an outer surface of the material tank. The switch is communicatively coupled to the float system through a wall of the material tank, and the switch is configured to send one or more signals to a control system when the float engages the switch.

First claim

The invention claimed is:

1. A material supply system, comprising:
a material sensor system coupled to a material tank configured to receive a material and output a flow of the material toward a spray component via pressurization within the material tank, wherein the material sensor system comprises:
a float system coupled to an inner surface of a wall of the material tank, wherein the float system comprises a float configured to float within a float cavity; and
a switch coupled to an outer surface of the wall of the material tank, wherein the switch is communicatively coupled to the float system through the wall of the material tank, and the wall of the material tank extends continuously between the float system and the switch to isolate the switch from an interior of the material tank;

a material mixer configured to receive the flow of the material from the material tank; and
a control system communicatively coupled to the material sensor system and to the material mixer, wherein the control system is configured to receive one or more signals from the material sensor system, and wherein the control system is configured to regulate operation of the material mixer based on the one or more signals.

2. The material supply system of claim 1 , wherein the switch is a pneumatic switch.

3. The material supply system of claim 1 , wherein the switch is configured to send the one or more signals to the control system when a quantity of the material within the material tank falls below a threshold level.

4. The material supply system of claim 1 , wherein the material to a material mixer is fluidly coupled between the material tank and the spray component.

5. The material supply system of claim 1 , wherein the material comprises paint, ink, water, resin, varnish, catalyst, one or more stains, one or more acids, solvent, or a combination thereof, wherein the material tank is configured to output the flow of the material to the material mixer, wherein the material mixer is fluidly coupled between the material tank and the spray component.

6. The material supply system of claim 1 , wherein the float is a first float, wherein the float system comprises a second float, wherein a magnet is disposed between the first float and the second float to structurally separate the first float from the second float, and wherein the switch is configured to send the one or more signals when the magnet engages the switch.

7. The material supply system of claim 1 , wherein the float system comprises a magnet disposed within an interior of the float.

8. The material supply system of claim 7 , wherein the switch is configured to send the one or more signals to the control system when the magnet engages the switch.

9. The material supply system of claim 1 , wherein the material sensor system is a first material sensor system, and the material supply system comprises a second material sensor system coupled to the material tank.

10. The material supply system of claim 9 , wherein the first and second material sensor systems are configured to send control signals to the control system corresponding to a quantity of the material within the material tank.

11. A material supply system, comprising:
a material tank configured to receive a material and output a flow of the material toward a spray component via pressurization within the material tank;
a material sensor system coupled to the material tank, wherein the material sensor system comprises:
a float system coupled to an inner surface of a wall of the material tank, wherein the float system comprises a float configured to float within a float cavity; and
a switch coupled to an outer surface of the wall of the material tank, wherein the switch is communicatively coupled to the float system through the wall of the material tank, wherein the wall of the material tank extends continuously between the float system and the switch to structurally separate the float system and the switch from one another, wherein the switch is configured to output one or more signals comprising information associated with the flow of the material;

a material mixer configured to receive the flow of the material from the material tank; and
a control system communicatively coupled to the material sensor system and to the material mixer, wherein the control system is configured to receive the one or more signals from the switch, wherein the control system is configured to determine a quantity of the material within the material tank based on the one or more signals and to adjust operation of the material mixer based on the quantity of the material within the material tank.

12. The material supply system of claim 11 , wherein the control system is configured to operate the material mixer to adjust blending of the material within the material mixer based on the quantity of the material within the material tank.

13. The material supply system of claim 11 , wherein the material mixer is configured to receive an additional flow of an additional material from an additional material tank, and the control system is configured to operate the material mixer to adjust blending of the material and the additional material within the material mixer based on the quantity of the material within the material tank.

14. The material supply system of claim 11 , wherein the control system is configured to terminate the flow of the material from the material tank to the material mixer based on the one or more signals.

15. The material supply system of claim 11 , wherein the switch is configured to send the one or more signals when the quantity of the material within the material tank falls below a threshold level.

16. The material supply system of claim 11 , wherein the float is a first float, wherein the float system comprises a second float, wherein a magnet is disposed between the first float and the second float to structurally separate the first float from the second float, and wherein the switch is configured to send the one or more signals when the magnet engages the switch.

17. The material supply system of claim 11 , wherein the float is one of a plurality of floats of the float system, wherein the float system comprises a magnet, and wherein the magnet is surrounded and sealed by the plurality of floats.

18. A material supply system, comprising:
