Abstract

A container-treatment machine having plural treatment stations for treating containers includes a transport element that rotates about a vertical machine axis, thereby moving the treatment stations circumferentially. A first transfer star supplies untreated containers simultaneously to corresponding treatment stations that are next to each other in the circumferential direction. A second transfer star removes treated containers simultaneously from corresponding treatment stations.

First claim

The invention claimed is:

1. An apparatus comprising a container-treatment machine, said container-treatment machine comprising a transport element, a plurality of treatment stations, a first transfer star, a second transfer star, a first transfer position, a second transfer position, and a first lifting device, wherein said transport element rotates about a vertical machine-axis, wherein said treatment stations are configured to treat containers, wherein said plurality of treatment stations rotates with said transport element, wherein said first transfer star supplies untreated containers to said transport element, wherein said second transfer star discharges treated containers from said transport element, wherein said first transfer star is configured in such a way that two untreated containers are simultaneously supplied to first and second treatment stations from said plurality of treatment stations, wherein said first and second treatment stations succeed one another in a circumferential direction of said transport element such that no treatment station is present between said first and second treatment stations, wherein said first lifting device is associated with said first transfer star, and wherein said first lifting device is configured for simultaneously lifting two untreated containers from said first and second transfer positions to said treatment stations.

2. The apparatus of claim 1 , wherein said first transfer star is configured such that said two untreated containers are simultaneously positioned beneath said first and second treatment stations in a single supply step.

3. The apparatus of claim 1 , wherein said first lifting device is stationary.

4. The apparatus of claim 1 , wherein said second transfer star comprises first and second transfer-star receptacles and wherein said second transfer star is configured such that said first transfer-star receptacle is positioned vertically beneath said first treatment station and said second transfer-star receptacle is positioned vertically beneath said second treatment station.

5. The apparatus of claim 1 , further comprising a second lifting device, wherein said second lifting device is associated with said second transfer star, wherein said second lifting device is configured to simultaneously transfer first and second treated containers to container receptacles of said second transfer star, wherein said second lifting device is configured to simultaneously lower first and second treated containers from said first and second treatment stations of said transport element to said first and second transfer positions.

6. The apparatus of claim 5 , wherein said second lifting device is stationary.

7. The apparatus of claim 1 , wherein said first transfer star comprises first recesses around a periphery thereof, said first recesses configured to operate as container receptacles for engaging untreated containers that are to be supplied, and wherein said second transfer star comprises second recesses around a periphery thereof, said second recesses comprising container receptacles, said second recesses being configured to operate as container receptacles for engaging treated containers to be discharged.

8. The apparatus of claim 1 , further comprising a delivery level and a treatment level above said delivery level, wherein supply of containers by said first transfer star takes place on said delivery level, wherein treatment of containers at said treatment stations takes place on said treatment level, and wherein discharge of containers by said second transfer star takes place on said delivery level.

9. The apparatus of claim 8 , further comprising a second lifting device, wherein said first lifting device lifts untreated containers from said delivery level to said treatment level, and wherein said second lifting device lowers treated containers from said treatment level to said delivery level.

10. The apparatus of claim 1 , wherein said treatment stations each comprise a holder for holding containers in a raised position.

11. The apparatus of claim 1 , wherein said transport element is configured to be driven independently of said first transport star, wherein said first transport star is configured to be driven independently of said second transport star, and wherein said second transport star is configured to be driven independently of said transport element.

12. The apparatus of claim 1 , wherein said first transport star is configured to alternately be indexed and intermittently driven, wherein said transport element is configured to alternately be indexed and intermittently driven, and wherein said second transfer star is configured to alternately be indexed or intermittently driven.

13. The apparatus of claim 1 , further comprising a second lifting device, wherein each of said first and second lifting devices comprises a neck-ring holder configured to at last partially encompass a container beneath a neck ring thereof.

14. The apparatus of claim 1 , further comprising a second lifting device, each of which is configured to transport containers in a vertical direction, wherein said first lifting device is configured to travel radially relative to a vertical axis of a container arranged at said first lifting device, and wherein said second lifting device is configured to travel radially relative to a vertical axis of a container arranged at said second lifting device.

15. The apparatus of claim 1 , further comprising a transporter running beneath said first and second transfer stars, wherein said transporter supplies untreated containers to said first transfer star and receives treated containers discharged from said second transfer star.

16. The apparatus of claim 1 , wherein said treatment stations comprise filling stations.

17. The apparatus of claim 1 , wherein said treatment stations comprise inspection stations.

18. The apparatus of claim 1 , wherein said treatment stations comprise cleaning stations.

19. A method for operating a container-treatment machine that comprises a transport element that rotates about a vertical machine axis and that has a plurality of treatment stations for treating containers, a first transfer star for supplying untreated containers to said transport element, a first lifting device associated with said first transfer star, a first transfer position, a second transfer position, and a second transfer star for discharging treated containers from said transport element, said method comprising supplying untreated containers to corresponding treatment stations that succeed one another in a circumferential direction of said transport element, causing said first lifting device to simultaneously lift two untreated containers from said first and second transfer positions to said treatment stations, and discharging treated containers from corresponding treatment stations that succeed one another in said circumferential direction of the transport element, wherein said untreated containers are supplied simultaneously to said corresponding treatment stations, and wherein said treated containers are discharged simultaneously from said corresponding treatment stations.
