Abstract

A method for processing containers includes periodically causing a reversible transporter to periodically transition between rotating in a first direction and rotating in a second direction that is opposite the first direction. When rotating in the first direction, the transporter feeds containers to a first processing region. When rotating in the second direction, the transporter feeds containers to a second processing region. Each processing region has as at least one processing position.

Claims

1. A method for processing containers, said method comprising receiving containers at a container inlet, moving said containers into container mounts of a reversible transporter, rotating said reversible transporter about a machine axis thereof, bringing said containers to processing positions that do not move with said reversible transporter, processing said containers at said processing positions, and after processing said containers, conveying said containers to a container outlet, wherein rotating said reversible transporter comprises periodically causing said reversible transporter to transition between rotating in a first direction and rotating in a second direction that is opposite said first direction, wherein rotating said reversible transporter in said first direction comprises feeding containers that are to be processed to a first processing region having at least one processing position, wherein rotating said reversible transporter in said second direction comprises feeding containers that are to be processed to a second processing region having at least one processing position, and, while processing containers at said first processing region, using said reversible transporter to feed containers that are to be processed into said second processing region.

2. The method of claim 1, further comprising disengaging a container from said reversible transporter prior to processing said container.

3. The method of claim 1, further comprising, while feeding containers that are to be processed into said first processing region, conveying containers that have already been processed at said first processing region to said container outlet.

4. The method of claim 1, further comprising selecting said reversible transporter to comprise a transport star comprising container mounts on a periphery thereof, wherein said container mounts are disposed at equal angular distances from one another relative to a machine axis.

5. The method of claim 4, further comprising selecting said container mounts to be container pockets, wherein said container pockets open in a peripheral direction.

6. The method of claim 4, further comprising selecting said container mounts to be container grippers, wherein said container grippers open in a peripheral direction.

7. The method of any one of claims 2, wherein disengaging a container from said reversible transporter prior to processing said container comprises raising said container out of engagement with said reversible transporter.

8. The method of claim 1, wherein said first processing region comprises plural processing positions, said method further comprising processing containers at said plural processing regions in parallel.

9. The method of claim 1, further comprising determining that the number of containers transferred into container mounts of said transporter is equal to the number of processing positions so that each processing position has one container to process, and restraining further feeding of containers.

10. The method of claim 1, further comprising pre-processing said containers at said first processing region, and, following said pre-processing, processing said containers at said second processing region.

11. An apparatus comprising a container-processing machine for processing containers, wherein said container-processing machine comprises a transporter, wherein said transporter comprises container mounts, wherein said transporter is rotatable about a machine axis in either a first direction or a second direction, wherein said transporter conveys containers that are to be processed and that have been fed through a container inlet to processing positions that do not move with said transporter, wherein said transporter conveys containers that have been processed from said processing positions to a container outlet, wherein, when said transporter rotates in said first direction, containers follow a first container path between said container inlet and said container outlet, wherein, when said transporter rotates in said second direction, containers follow a second container path between said container inlet and said container outlet, wherein said first container path traverses a first processing region, wherein said second container path traverses a second processing region, wherein said first and second processing regions comprise said processing positions, and wherein said first and second processing regions are on opposite sides of a mid-plane of said transporter.

12. The apparatus of claim 11, further comprising a machine controller, wherein said machine controller is configured to control said container processing machine, and wherein said controller is configured to periodically reverse rotation of said transporter.

13. The apparatus of claim 11, wherein each processing position comprises a lifter, wherein said lifter is configured to raise a container, and wherein said lifter is configured to disengage said container from said transporter.

14. The apparatus of claim 13, wherein each processing position comprises a container carrier, wherein said lifter controls said container carrier, wherein said lifter causes said container carriers to move between a lower position and an upper position for lifting and lowering said container.

15. The apparatus of claim 14, wherein said container carrier comprises a suspender sized to engage a neck ring of a container.

16. The apparatus of claim 14, wherein said container carrier comprises a support surface sized to engage a base of a container.

17. The apparatus of claim 11, wherein said transporter comprises a star having container mounts around a periphery thereof, wherein said container mounts comprise container pockets, wherein said container mounts are distributed around said periphery according to a pitch angle, wherein each container mount is separated from adjacent container mounts by said pitch angle.

18. The apparatus of claim 11, wherein said first and second processing regions comprise equal numbers of processing positions.

19. The apparatus of claim 17, wherein said processing positions are distributed around said periphery according to said pitch angle, wherein each processing positions is separated from adjacent processing positions by said pitch angle.

20. The apparatus of claim 11, further comprising a transport belt, wherein said transport belt comprises a first section that forms said container inlet and a second section that forms said container outlet, wherein said transport belt extends beneath said transporter.

21. The apparatus of claim 11, wherein at least one of said processing positions comprises a filling position.
