Box carrier

1. A system for transporting open boxes along a direction of travel in a packaging machine, said system including a plurality of box carriers disposed in said packaging machine, each box carrier being movable along the direction of travel, each box carrier having at least one contact surface for contacting and supporting an open box, each box carrier having its own, separate dedicated vacuum reservoir permanently attached to said contact surface and movable therewith, each box carrier having at least one suction opening extending through said contact surface and fluidically connected to said vacuum reservoir for holding said box against said contact surface by suction as the box carrier is moving such that each box carrier maintains negative pressure on its own with the box carrier's separate dedicated vacuum reservoir.

2. The system as defined in claim 1 , wherein the contact surface has a plurality of suction openings.

3. The system as defined in claim 1 , wherein said system includes at least one venting station disposed along said direction for drawing a vacuum in each vacuum reservoir and at least one ventilating station disposed along said direction for relieving said vacuum in each vacuum reservoir, whereby as said each box carrier is transported along said direction, a valve on said box carrier is actuated by said venting station to create a vacuum in said reservoir for holding said box against said support surface, and actuated by said ventilation station to relieve vacuum in said reservoir for releasing said box from said support surface.

4. The system as defined in claim 3 , wherein said valve is a touch check valve for sensing said venting or ventilating stations.

5. The system as defined in claim 3 , wherein the contact surface has a plurality of suction openings.

6. The system as defined in claim 4 , wherein the contact surface has a plurality of suction openings.

7. The system as defined in claim 1 , wherein a position stop is provided on said contact surface.

8. The system as defined in claim 2 , wherein a position stop is provided on said contact surface.

9. The system as defined in claim 3 , wherein a position stop is provided on said contact surface.

10. A method for closing an open box, transported by a system as defined by claim 1 , having the steps of closing the open box with a closing device while holding the open box against said contact surface with said at least one suction opening.

11. A method for closing an open box, transported by a system as defined by claim 2 , having the steps of closing the open box with a closing device while holding the open box against said contact surface with said plurality of suction openings.

12. A method for closing an open box, transported by a system as defined by claim 3 , having the steps of closing the open box with a closing device while holding the open box against said contact surface with said at least one suction opening.

13. A method for closing an open box, transported by a system as defined by claim 4 , having the steps of closing the open box with a closing device while holding the open box against said contact surface with said at least one suction opening.

14. A method for closing an open box, transported by a system as defined by claim 5 , having the steps of closing the open box with a closing device while holding the open box against said contact surface with said plurality of suction openings.

15. A method for closing an open box, transported by a system as defined by claim 6 , having the steps of closing the open box with a closing device while holding the open box against said contact surface with said plurality of suction openings.

16. A method for closing an open box, transported by a system as defined by claim 7 , having the steps of closing the open box with a closing device while holding the open box against said contact surface with said at least one suction opening.

17. A method for closing an open box, transported by a system as defined by claim 8 , having the steps of closing the open box with a closing device while holding the open box against said contact surface with said plurality of suction openings.

18. A method for closing an open box, transported by a system as defined by claim 9 , having the steps of closing the open box with a closing device while holding the open box against said contact surface with said at least one suction opening.

19. The system of claim 1 , further comprising a conveyor, each of the plurality of box carriers being disposed on the conveyor, the conveyor configured to move the plurality of boxes along the direction of travel.

20. The system of claim 19 , wherein the direction of travel includes direction along both a curved section of the conveyor and a straight section of the conveyor.

21. The system of claim 19 , wherein the number of box carriers on the conveyor is equivalent to the number of boxes being moved along the direction of travel.

22. A system for transporting open boxes along a direction of travel in a packaging machine, said system including a plurality of box carriers disposed in said packaging machine, each box carrier being movable along the direction of travel, each box carrier having at least one contact surface for contacting and supporting an open box, each box carrier having its own, separate dedicated vacuum reservoir permanently attached to said contact surface and movable therewith, each box carrier having at least one suction opening extending through said contact surface and fluidically connected to said vacuum reservoir for holding said box against said contact surface by suction as the box carrier is moving, and wherein the vacuum reservoir includes a valve adapted to be activated for venting and ventilating said vacuum reservoir thereby holding or releasing said box from said contact surface.
