Abstract

An apparatus and method are presented for removing container covers within a controlled environment enclosure without using gloves. The apparatus comprises an articulated arm apparatus and a gripping apparatus and can further comprise a controller. The articulated arm apparatus can be configurable for holding and moving a container in three dimensions; and the gripping apparatus can be configured for gripping a container cover sealing the container. The method comprises moving the container using the articulated arm apparatus while holding a gripping area of the container cover substantially stationary using the gripping apparatus. The apparatus can further comprise a sensor configured for supplying information to the controller for determining the location of the container cover gripping area and an orientation of the container cover. The method can further comprise inspecting the container cover using the sensor. The container can be moved along a path and within a space determined by the controller.

First claim

What is claimed is:

1. A method for removing within a controlled aseptic environment enclosure a container cover from a sealed container, the sealed container sealed by the container cover, the method comprising moving the container while holding a gripping area of the container cover stationary wherein moving the container comprises holding the container with an articulated arm apparatus disposed within the controlled aseptic environment; and removing the container cover is achieved by moving the container with respect to the gripping area during a first manipulation of the articulated arm apparatus.

2. The method of claim 1 , further comprising positioning along a trajectory the sealed container within a reach of a gripping apparatus disposed within the controlled environment by a second manipulation of the articulated arm apparatus; and gripping the gripping area with the gripping apparatus.

3. The method of claim 2 , wherein the positioning the sealed container comprises placing the gripping area of the container cover between two gripping elements of the gripping apparatus, the first and second of the two gripping elements respectively comprising first and second mutually parallel and mutually engagable grip surfaces.

4. The method of claim 3 , further comprising rotating at least one of the gripping elements.

5. The method of claim 4 , wherein the positioning the gripping area between the two gripping elements comprises placing the gripping area proximate and facing the first grip surface.

6. The method of claim 5 , wherein the rotating at least one of the gripping elements comprises moving the second of the two gripping elements in a plane parallel to the first grip surface.

7. The method of claim 6 , wherein the positioning further comprises straightening the gripping area if the gripping area is bent toward the first grip surface by contacting to the first grip surface to one of the gripping area and a part of the cover in contact with the gripping area.

8. The method of claim 7 , wherein the moving the second gripping element comprises straightening the gripping area if the gripping area is bent toward the second gripping element by contacting the second grip surface to the other of the gripping area and the part of the cover in contact with the gripping area.

9. The method of claim 2 , further comprising at least one of lowering the container and rotating the container about an axis in a plane, defined by the cover by a third manipulation of the articulated arm apparatus.

10. The method of claim 9 , wherein the at least one of rotating and raising the gripping area is to an extent that allows the gripping apparatus to remain clear of the container during the removing the container cover.

11. The method of claim 2 , wherein the removing the container cover is removing the container cover simultaneously along two edges of the container.

12. The method of claim 2 , wherein the first manipulation of the articulated arm apparatus comprises moving the container with respect to the gripping apparatus.

13. The method of claim 12 , where in the moving the container with respect to the gripping apparatus comprises moving the container along a predetermined path within a predetermined space.

14. The method of claim 13 , wherein at least one of the predetermined path and the predetermined space is determined using a controller.

15. The method of claim 13 , wherein the predetermined path is a circular path.

16. The method of claim 2 , wherein the moving the container with respect to the gripping apparatus comprises moving the container diagonally with respect to the gripping apparatus.

17. The method of claim 2 , wherein the trajectory is based on information obtained from a sensor.

18. The method of claim 17 , wherein the information comprises at least one of position information and orientation information about the gripping area.

19. The method of claim 2 , further comprising inspecting the container cover using a sensor.

20. The method of claim 19 , further comprising
selecting an alternative gripping area of the container cover based on the inspecting;
gripping the alternative gripping area with the gripping apparatus; and
removing the container cover by moving the container.

21. The method of claim 2 , further comprising moving the gripping apparatus away from an operational area of the articulated arm apparatus after removing the container cover.
