Abstract

Described is a machine for printing containers such as bottles or cans, with a plurality of treatment stations, on which printing heads and if applicable further devices required for the pre-treatment and post-treatment of the containers are provided, with a carrier for a plurality of containers, which are arranged next to one another on the carrier. In the process it is provided that the carrier can be transported via a conveyor belt from one treatment station to the next, in that a plurality of treatment stations each are arranged in line next to one another substantially transversely to the conveyor belt, in that the carrier is arranged substantially transversely to the conveyor belt and in that the treatment stations and the carrier can be moved relative to one another in substantially vertical direction. Instead of the conveyor belt, a rotary device can also be provided.

Claims

1. A machine for printing containers such as bottles or cans, the machine comprising:

a conveyor belt,

a plurality of treatment stations, the plurality of treatment stations are arranged in series next to one another substantially transversely to the conveyor belt, wherein at least one of the plurality of treatment stations comprise a plurality of printing heads,

a carrier substantially arranged transversely to the conveyor belt, wherein the plurality of containers are arranged on the carrier and the carrier can be transported via the conveyor belt from one of the treatment stations to another of the treatment stations,

a lifting device, wherein the lifting device raises the carrier with the containers in a vertical direction off the conveyor belt toward a top of each of the treatment stations when the carrier is in the treatment station.

2. The machine according to claim 1, wherein the plurality of printing heads are arranged annularly about the containers.

3. The machine according to claim 2, wherein the printing heads are attached to a retaining plate annularly and are aligned with respect to one another.

4. The machine according to claim 2, wherein the plurality of printing heads comprise four to seven printing heads arranged annularly about each container in each treatment station.

5. The machine according to claim 1, further comprising turntables provided on the carrier for receiving the containers, the containers being held on the turntables through low pressure or vacuum.

6. The machine according to claim 5, wherein the carrier is hollow and further comprises laterally arranged end plates running in guides and connected to the at least one low pressure or vacuum channel such that the low pressure or vacuum can be supplied to the turntables on the carrier.

7. The machine according to claim 1, further comprising at least one fixed low pressure or vacuum channel for providing the low pressure or vacuum for holding the containers on the turntables.

8. The machine according to claim 1, further comprising a centering device, being placed onto each of the containers.

9. The machine according to claim 8, wherein the centring device is configured to be lifted off, lowered, rotated and or driven by means of a motor or rotary drive.

10. The machine according to claim 1, further comprising centering devices with motors or rotary drives being assigned to the containers, which are configured to be lifted along their longitudinal axis by the containers arranged on the carrier when the carrier is lifted.

11. The machine according to claim 1, the plurality of treatment stations are arranged in at least one row, the at least one row further comprises one or a plurality of cover/s which can be closed off if required.

12. The machine according to claim 1, the plurality of treatment stations are arranged in at least one row, the at least one row further comprises a common cover which can be closed off through the carrier.

13. The machine according to claim 1, wherein the carrier can be mechanically braced against each treatment station.

14. The machine according to claim 13, wherein the carrier can be mechanically braced against each treatment station through an eccentric clamp.

15. The machine according to claim 1, wherein the plurality of treatment stations comprise a same type of treatment stations.

16. The machine according to claim 1, wherein the treatment stations are fastened to a floor separately from the carrier.

17. The machine according to claim 1, wherein the plurality of treatment stations are arranged in two to four rows, one after the other, and each treatment station is of the same type.

18. The machine for printing containers according to claim 1, wherein the plurality of treatment stations include a pre-treatment device and a post-treatment device.

19. A machine for printing containers such as bottles or cans, the machine comprising:

a rotary device rotating about a rotary center,

a plurality of treatment stations, the plurality of treatment stations are arranged in series next to one another substantially radially to the rotary center, wherein at least one of the plurality of treatment stations comprises a plurality of printing heads,

a carrier substantially arranged radially to the rotary center, wherein a plurality of containers are arranged on the carrier and the carrier can be transported from one of the treatment stations to another of the treatment stations with the rotary device,

a lifting device, wherein the lifting device raises the carrier with the containers in a vertical condition off the rotary device toward a top of each of the treatment stations when the carrier is in the treatment station.

20. The machine for printing containers according to claim 19, wherein the plurality of treatment stations include a pre-treatment and a post-treatment of the device.
