Abstract

A method for converting a first container stream into a second container stream that has a different width from said first container stream includes moving a container from the first container stream to a first transfer position, at the first transfer position, using a container holder of a conversion section to grip the container, to move it along a third transport direction until it arrives at a selected one of a several second transfer positions, and to then release it onto the second transport section, thereby enabling the container to join the second container stream. The second transfer positions are offset relative to each other in a direction along the second width.

First claim

The invention claimed is:

1. An apparatus for transporting containers, said apparatus comprising a transport device, said transport device comprising a first transport section, a second transport section, and a conversion section, wherein said first transport section comprises a first transfer position, wherein said conversion section comprises a plurality of second transfer positions, a container holder, and a container gripper, wherein said first transport section conveys a first container stream along a first transport direction, said first container stream having a first width, wherein said second transport section conveys a second container stream along a second transport direction, said second container stream having a second width that differs from said first width, wherein said conversion section is disposed between said first and second transport sections, wherein said conversion section is configured to pass containers at said first transport section in a controlled manner to any one of said second transfer positions, wherein said second transfer positions are distributed along a third transport direction that extends along said conversion section, wherein said container holder is movable in a controlled manner along said third transport direction between said first transfer position and any one of said second transfer positions, wherein said gripper is configured to grip a container at said first transfer position and to carry said container along said third transport direction to any one of said second transfer positions, wherein said container holder comprises an arm, wherein said container gripper is at an end of said arm, and wherein said arm is configured to swivel.

2. The apparatus of claim 1 , wherein said second transport section is a multi-track transport section comprising a plurality of tracks, each of said tracks defining a container row.

3. The apparatus of claim 1 , wherein said first transport section conveys a container stream having a first number of container tracks, wherein said second transport section comprises a second number of container tracks, wherein said second number is greater than said first number.

4. The apparatus of claim 3 , wherein said first transport section is configured to convey a single-track container stream, and wherein said second transport section is configured to convey a multi-track container stream.

5. The apparatus of claim 1 , wherein said container holder is configured to move along a velocity vector having a component directed along said first transport direction and a component directed along said second transport direction.

6. The apparatus of claim 1 , wherein said first, second and third transport directions are horizontal transport directions.

7. The apparatus of claim 1 , wherein said container holder is movable along a closed movement path on said conversion section, wherein said closed movement path comprises a portion that extends between said first transfer position and a second transfer position.

8. The apparatus of claim 1 , wherein said container holder is configured to permit controlled sideways movement of said container gripper when said container is set down at said second transfer position.

9. An apparatus for transporting containers, said apparatus comprising a transport device, said transport device comprising a first transport section, a second transport section, and a conversion section, wherein said first transport section comprises a first transfer position, wherein said conversion section comprises a plurality of second transfer positions, a container holder, and a container gripper, wherein said first transport section conveys a first container stream along a first transport direction, said first container stream having a first width, wherein said second transport section conveys a second container stream along a second transport direction, said second container stream, said second container stream having a second width that differs from said first width, wherein said conversion section is disposed between said first and second transport sections, wherein said conversion section is configured to pass containers at said first transport section in a controlled manner to any one of said second transfer positions, wherein said second transfer positions are distributed along a third transport direction that extends along said conversion section, wherein said container holder is movable in a controlled manner along said third transport direction between said first transfer position and any one of said second transfer positions, wherein said gripper is configured to grip a container at said first transfer position and to carry said container along said third transport direction to any one of said second transfer positions, and wherein said conversion section comprises a plurality of container holders, each of which is controllable to move independently of all other container holders.

10. The apparatus of claim 9 , wherein said container holder comprises a swivel arm having said container gripper at an end thereof.

11. The apparatus of claim 9 , wherein said second transport section is a multi-track transport section in which each track defines a row of containers.

12. An apparatus for transporting containers, said apparatus comprising a transport device, said transport device comprising a first transport section, a second transport section, and a conversion section, wherein said first transport section comprises a first transfer position, wherein said conversion section comprises a plurality of second transfer positions, a container holder, and a container gripper, wherein said first transport section conveys a first container stream alone a first transport direction, said first container stream having a first width, wherein said second transport section conveys a second container stream along a second transport direction, said second container stream, said second container stream having a second width that differs from said first width, wherein said conversion section is disposed between said first and second transport sections, wherein said conversion section is configured to pass containers at said first transport section in a controlled manner to any one of said second transfer positions, wherein said second transfer positions are distributed, along a third transport direction that extends along said conversion section, wherein said container holder is movable in a controlled manner along said third transport direction between said first transfer position and any one of said second transfer positions, and wherein said gripper is configured to grip a container at said first transfer position and to carry said container along said third transport direction to any one of said second transfer positions, said apparatus further comprising an electric linear motor, wherein said electric linear motor comprises a stator, wherein said container holder comprises a support guided on said stator, and wherein said container gripper is coupled to said support.

13. The apparatus of claim 12 , wherein said electric linear motor further comprises an armature, wherein said armature comprises said support.

14. The apparatus of claim 12 , wherein said container holder comprises an arm, wherein said container gripper is at an end of said arm, and wherein said arm is configured to translate relative to said support.

15. The apparatus of claim 12 , further comprising an arm configured to swivel, said arm containing a constituent of said container holder and having said container gripper at an end thereof.

16. The apparatus of claim 12 , wherein said second transport
