1. A device for removing caps from vessels, said device comprising:
- first vessel holding means for holding a first vessel therein;
a cap holding means adjacent said first vessel holding means, said cap holding means including holding elements for holding a cap of the first vessel;
moving means coupled to said cap holding means for moving the cap holding means in a direction which is parallel to an axis of the first vessel, and for rotating the cap holding means around the axis of the first vessel wherein said moving means comprises a threaded rod attached to said cap holding means, said threaded rod being engaged in a rotatable nut;
said device further comprisingholding means for selectively holding the rotatable nut, thereby selectively preventing the rotatable nut from rotating, thereby enabling selective conversion of a rotation of the threaded rod into linear movement of the cap holding means.

Abstract
Device for pulling out or twisting off caps from vessels, wherein the vessel is held, and the cap is removed by means of a cap-holding device; the cap-holding device executes both a linear movement in direction of the vessel axis as well as a rotating movement around the vessel axis. The cap-holding device advantageously has several clamping jaws that are pressed against the circumference of the cap.

21. A device for removing caps from vessels, said device comprising:
-
first vessel holding means for holding a first vessel therein; a cap holding means adjacent said first vessel holding means, said cap holding means including holding elements for holding a cap of the first vessel; moving means coupled to said cap holding means for moving the cap holding means in a direction which is parallel to an axis of the first vessel, and for rotating the cap holding means around the axis of the first vessel, wherein the holding elements of the cap holding means comprise at least two clamping jaws having a space therebetween, each of said at least two clamping jaws being movable from a first position to a second position by a drive means, wherein the space between the at least two clamping jaws when the clamping jaws are in the first position is larger than a diameter of the cap whereby the cap can be disposed in the space, and wherein, when the at least two clamping jaws are moved to the second position, the at least two clamping jaws engage an outer circumference of the cap, wherein an edge of each of the clamping jaws includes a toothed portion thereupon, said toothed portion for engaging the cap, and wherein each toothed portion comprises a plurality of individual teeth, with the individual teeth decreasing in size from a first side of the edge to a second side of the edge.

22. A device for removing caps from vessels, said device comprising:
-
first vessel holding means for holding a first vessel therein; a cap holding means adjacent said first vessel holding means, said cap holding means including holding elements for holding a cap of the first vessel; moving means coupled to said cap holding means for moving the cap holding means in a direction which is parallel to an axis of the first vessel, and for rotating the cap holding means around the axis of the first vessel; and a second vessel holding means configured to move at least the first vessel and a second vessel with respect to said cap holding means, such that when the first vessel holding means is disposed below the cap holding means, the second vessel holding means is disposed to receive the second vessel therebetween, and wherein the first and second vessel holding means can be moved through movement of a common rotating arm, thereby moving the first and second vessels relative to said cap holding means.

23. A device for removing caps from vessels, said device comprising:
-
first vessel holding means for holding a first vessel therein; a cap holding means adjacent said first vessel holding means, said cap holding means including holding elements for holding a cap of the first vessel; moving means coupled to said cap holding means for moving the cap holding means in a direction which is parallel to an axis of the first vessel, and for rotating the cap holding means around the axis of the first vessel; and a grabbing means for grabbing and moving the first vessel from a rack to the first vessel holding means.

24. A method for removing caps from vessels, said method comprising the steps of:
-
holding a vessel in a vessel holder; holding a cap of the vessel in a cap holding device; linearly and rotatingly moving the cap holding device through actuation of a moving means, thereby removing the cap from the vessel, wherein said step of pulling the vessel from a rack comprises steps of engaging the vessel with a grabbing means at a first pressure; relieving the first pressure and moving the grabbing means in a direction whereby the grabbing means engages the vessel and an upper portion thereof, under an upper edge thereof. - View Dependent Claims (25, 26, 27)
