Abstract

A method for securing a closure on a cylindrical container (such as a pharmaceutical vial) includes: positioning a closure in a first position, the closure being substantially centered via a centering assembly along an axis that is generally normal to the closure; translating the substantially centered closure along the axis to a second position; positioning a cylindrical container, the container being substantially centered via the centering assembly along the axis; translating the substantially centered closure along the axis to a third position in which it is adjacent the substantially centered container; and relatively rotating the closure and the container to secure the closure to the container. With such a method, both the closure and the cylinder can be centered along the axis, thereby registering them with each other for reliable securing.

Claims

1. A method for securing a closure on a cylindrical container, comprising:

positioning a closure in a first position, the closure being substantially centered via a centering assembly along an axis that is generally normal to the closure;

translating the substantially centered closure along the axis to a second position;

positioning a cylindrical container, the container being substantially centered via the centering assembly along the axis;

translating the substantially centered closure along the axis to a third position in which it is adjacent the substantially centered container; and

relatively rotating the closure and the container to secure the closure to the container;

wherein the step of positioning the closure comprises positioning the closure on a stage, and wherein the step of positioning the cylindrical container comprises positioning the container on the stage.

2. The method defined in claim 1, wherein the step of relatively rotating the closure and the container comprises rotating the stage and the container while maintaining the closure substantially stationary.

3. The method defined in claim 1, wherein the step of positioning the closure further comprises depositing the closure within a confined region on the stage and urging the closure within the confined region to the first position.

4. The method defined in claim 3, wherein the step of urging the closure comprises rotating a plurality of clamps with arcuate edges into contact with the closure, each of the clamps being rotated about a respective clamp axis of rotation that is parallel to and offset from the axis that is normal to the closure.

5. The method defined in claim 1, wherein the step of translating the closure comprises capturing the substantially centered closure on the stage and raising the substantially centered closure from the stage with an elevator.

6. The method defined in claim 5, wherein the capturing step comprises applying suction to the closure.

7. The method defined in claim 6, further comprising the step of maintaining suction on the closure after the step of translating the closure to a third position.

8. The method defined in claim 1, wherein the step of positioning the container further comprises depositing the container within a confined region on the stage and urging the container within the confined region to the substantially central position.

9. The method defined in claim 8, wherein the step of urging the container comprises rotating a plurality of clamps with arcuate edges into contact with the container, each of the clamps being rotated about a respective clamp axis of rotation that is parallel to and offset from the axis that is normal to the closure.

10. The method defined in claim 1, wherein further comprising the step of receiving the closure on the stage from a chute that exits into the main stage.

11. A method for securing a closure on a cylindrical container, comprising:

positioning a closure in a first position on a positioning stage, the closure being substantially centered via centering members of a centering assembly along an axis that is generally normal to the closure;

translating the substantially centered closure along the axis to a second position;

positioning a cylindrical container on the positioning stage, the container being substantially centered via the centering members of the centering assembly along the axis;

translating the substantially centered closure along the axis to a third position in which it is adjacent the substantially centered container; and

relatively rotating the closure and the container to secure the closure to the container.

12. The method defined in claim 11, wherein the step of relatively rotating the closure and the container comprises rotating the positioning stage and the container while maintaining the closure substantially stationary.

13. The method defined in claim 11, wherein the step of positioning the closure further comprises depositing the closure within a confined region on the positioning stage and urging the closure within the confined region to the first position.

14. The method defined in claim 13, wherein the centering members comprise a plurality of clamps with arcuate edges, and wherein the step of urging the closure comprises rotating the plurality of clamps into contact with the closure, each of the clamps being rotated about a respective clamp axis of rotation that is parallel to and offset from the axis that is normal to the closure.

15. The method defined in claim 11, wherein the step of translating the closure comprises capturing the substantially centered closure on the positioning stage and raising the substantially centered closure from the positioning stage with an elevator.

16. The method defined in claim 15, wherein the capturing step comprises applying suction to the closure.

17. The method defined in claim 16, further comprising the step of maintaining suction on the closure after the step of translating the closure to a third position.

18. The method defined in claim 11, wherein the step of positioning the container further comprises depositing the container within a confined region on the stage and urging the container within the confined region to the substantially central position.

19. The method defined in claim 18, wherein the centering members comprise a plurality of clamps with arcuate edges, and wherein the step of urging the container comprises rotating the clamps into contact with the container, each of the clamps being rotated about a respective clamp axis of rotation that is parallel to and offset from the axis that is normal to the closure.

20. The method defined in claim 11, wherein further comprising the step of receiving the closure on the stage from a chute that exits into the main stage.
