Abstract

An acoustic force assisted painting system has a housing, at least one nozzle and at least one acoustic emitter. The housing has a conduit for receiving paint from an external source into the housing. The at least one nozzle is disposed in the housing. The at least one nozzle has an inlet that is fluidly connected to the conduit to receive paint from the conduit. The at least one nozzle has an outlet that dispenses paint. The least one acoustic emitter is disposed in the housing at a location downstream of the inlet with respect to the conduit.

First claim

What is claimed is:

1. An acoustic force assisted painting system comprising:
a housing having a conduit for receiving paint from an external source into the housing, the housing having at least one acoustic chamber having at plurality of side walls defining an open space of the at least one acoustic chamber;
at least one nozzle disposed in the housing, the at least one nozzle having an inlet that is fluidly connected to the conduit to receive paint from the conduit, the at least one nozzle having an outlet that dispenses paint; and
at least one acoustic emitter supported on at least one side wall of the plurality of sidewalls at a location downstream of the inlet with respect to the conduit, the at least one acoustic emitter being configured to emit an acoustic force from the at least one acoustic chamber past the open space towards the nozzle;
wherein the at least one acoustic emitter is positioned closer to the outlet than to the inlet of the at least one nozzle;
wherein the at least one nozzle includes a plurality of nozzles, each of the plurality of nozzles having a respective inlet that is fluidly connected to the conduit that receives paint;
wherein the plurality of nozzles extends through the open space of the acoustic chamber;
wherein the acoustic chamber includes an upstream side wall and a downstream side wall, the downstream side wall being positioned closer to respective outlets of the plurality of nozzles than to the respective inlets, and the at least one acoustic emitter being positioned on the downstream side wall;
wherein the downstream side wall of the acoustic chamber includes a plurality of openings, each of the openings receiving one of the outlets of the plurality of nozzles;
wherein each of the plurality of openings extend into a plurality of channels that each open to an exterior of the housing.

2. The acoustic force assisted painting system according to claim 1 , wherein the plurality of nozzles are arranged in an array of successive rows and columns within the housing.

3. The acoustic force assisted painting system according to claim 2 , wherein
the at least one acoustic emitter includes a plurality of acoustic emitters arranged in successive rows in the acoustic chamber, each of the acoustic emitters corresponding to one of the successive rows of the nozzles.

4. The acoustic force assisted painting system according to claim 2 , wherein
the at least one acoustic emitter includes a plurality of acoustic emitters arranged in successive rows in the acoustic chamber, each of the acoustic emitters corresponding to more than one of the successive rows of the nozzles.

5. The acoustic force assisted painting system according to claim 4 , wherein
the housing includes a paint reservoir that receives paint from the conduit, the housing further including a plurality of walls extending from the paint reservoir to the acoustic chambers, the plurality of walls forming a plurality of sub-reservoirs for storing paint and a plurality of acoustic sub-chamber.

6. The acoustic force assisted painting system according to claim 5 , wherein
each of the acoustic sub-chamber includes a plurality of nozzles extending therethrough.

7. The acoustic force assisted painting system according to claim 6 , wherein
each of the acoustic sub-chamber includes a single acoustic emitter of the plurality of acoustic emitters.

8. The acoustic force assisted painting system according to claim 6 , wherein
each of the acoustic sub-chamber includes more than one acoustic emitter of the plurality of acoustic emitters.

9. The acoustic force assisted painting system according to claim 8 , wherein
each of the acoustic sub-chamber includes four acoustic emitters arranged to be separated by 90 degree angles.

10. The acoustic force assisted painting system according to claim 1 , wherein the at least one acoustic emitter is positioned upstream of the outlets at a location within the vicinity of the outlets.

11. The acoustic force assisted painting system according to claim 10 , wherein
the at least one acoustic emitter includes an acoustic transducer.

12. The acoustic force assisted painting system according to claim 3 , wherein
the plurality of acoustic emitters includes a plurality of acoustic transducers.

13. The acoustic force assisted painting system according to claim 1 , wherein the housing includes a first airflow channel extending through the plurality of channels in a first direction to enable external air to flow through the plurality of channels in the first direction, and the housing includes a second airflow channel extending through the plurality of channels in a second direction that is transverse to the first direction to enable external air to flow in the second direction.

14. The acoustic force assisted painting system according to claim 1 , wherein
the at least one acoustic transmitter is spaced from the at least one nozzle.
