Abstract

A method of measuring a nozzle deflection at the time of jetting is provided. The method includes rotating a nozzle; inserting a spout of the nozzle into a container through an opening of the container; ejecting liquid from the nozzle inside the container; and measuring a nozzle deflection outside the container while the nozzle is rotating and ejecting the liquid.

First claim

What is claimed is:

1. A method of measuring a nozzle deflection, comprising:
rotating a nozzle having a cylindrical shaft body and a spout located at a distal end portion of the shaft body;
inserting the spout into a tank-shaped container through an opening of the container, the opening having a radius larger than a sum of a radius of the shaft body and a maximum allowable deflection amount of the nozzle;
ejecting liquid from the nozzle in a state where the spout is disposed inside the container; and
measuring a nozzle deflection outside the container while the nozzle is rotating and ejecting the liquid in a state where the spout is disposed inside the container.

2. The method of measuring a nozzle deflection according to claim 1 , further comprising:
bouncing the liquid ejected from the nozzle at an inside wall surface of the container; and
colliding the bounced liquid with a folded back portion arranged entire circumference of the opening.

3. The method of measuring a nozzle deflection according to claim 1 , further comprising:
discharging the liquid ejected from the nozzle out of the container.

4. The method of measuring a nozzle deflection according to claim 1 , wherein the measuring the nozzle deflection includes measuring the nozzle deflection in a non-contact manner.

5. The method of measuring a nozzle deflection according to claim 4 , wherein the measuring the nozzle deflection includes measuring the nozzle deflection by using a laser.

6. The method of measuring a nozzle deflection according to claim 3 , wherein the discharging the liquid includes discharging the liquid ejected from the nozzle out of discharge port of the container by gravity.

7. The method of measuring a nozzle deflection according to claim 1 , wherein the ejecting liquid includes ejecting liquid having a pressure of between 2 to 250 MPa from the nozzle inside the container.

8. The method of measuring a nozzle deflection according to claim 2 , further comprising:
discharging the liquid ejected from the nozzle out of the container.

9. The method of measuring a nozzle deflection according to claim 2 , wherein the measuring the nozzle deflection includes measuring the nozzle deflection in a non-contact manner.

10. The method of measuring a nozzle deflection according to claim 3 , wherein the measuring the nozzle deflection includes measuring the nozzle deflection in a non-contact manner.

11. The method of measuring a nozzle deflection according to claim 9 , wherein the measuring the nozzle deflection includes measuring the nozzle deflection by using a laser.

12. The method of measuring a nozzle deflection according to claim 10 , wherein the measuring the nozzle deflection includes measuring the nozzle deflection by using a laser.

13. The method of measuring a nozzle deflection according to claim 8 , wherein the discharging the liquid includes discharging the liquid ejected from the nozzle out of discharge port of the container by gravity.

14. The method of measuring a nozzle deflection according to claim 2 , wherein the ejecting liquid includes ejecting liquid having a pressure of between 2 to 250 MPa from the nozzle inside the container.

15. The method of measuring a nozzle deflection according to claim 3 , wherein the ejecting liquid includes ejecting liquid having a pressure of between 2 to 250 MPa from the nozzle inside the container.

16. The method of measuring a nozzle deflection according to claim 4 , wherein the ejecting liquid includes ejecting liquid having a pressure of between 2 to 250 MPa from the nozzle inside the container.

17. The method of measuring a nozzle deflection according to claim 5 , wherein the ejecting liquid includes ejecting liquid having a pressure of between 2 to 250 MPa from the nozzle inside the container.
