Abstract

A container treatment apparatus includes a transport apparatus for transporting containers along a predetermined transport path, wherein the transport apparatus has at least one transport device ( 100 ) for transporting the containers ( 100 ) and at least one container treatment device ( 150 ) for treating the container in a predetermined manner, wherein the transport devices include a rotatable carrier on which a plurality of holding elements ( 40 ) for holding at least one container is arranged. The container treatment device is arranged to treat the containers transported by the transport device and the holding element is rotatable such that the container held by the holding element is rotatable with respect to its longitudinal direction and the container treatment apparatus includes a monitoring device for monitoring the rotational movement of the containers.

First claim

The invention claimed is:

1. A container treatment apparatus comprising a transport apparatus for transporting containers along a predetermined transport path, wherein the transport apparatus comprises at least one transport device for transporting the containers and at least one container treatment device for treating the container in a predetermined manner, wherein said transport device comprises a carrier on which a plurality of holding elements for holding at least one container is arranged,
wherein
the container treatment device is arranged to handle the containers transported by the transport device and the holding element is rotatable such that the container held by said holding element is rotatable with respect to its longitudinal direction and the container treatment apparatus comprises monitoring device for monitoring the rotational movement of the containers.

2. The container treatment apparatus according to claim 1 ,
wherein
these holding elements are movable relative to the carrier in such a way that a distance between two containers immediately following one another on the transport path is variable.

3. The container treatment apparatus according to claim 1 ,
wherein
the container treatment device is configured to treat an outer surface of the containers.

4. The container treatment apparatus according to claim 1 ,
wherein
the transport device has at least one drive device, configured to rotate the containers held by the holding elements with respect to their longitudinal axis, wherein the at least one drive device generates the rotary movement of the containers without contact and/or by magnetic forces.

5. The container treatment apparatus according to claim 1 ,
wherein
the container treatment device is selected from a group of container treatment devices which includes container outer surface treatment devices, container inner surface treatment devices, container inspection devices, container printing devices, and container marking devices.

6. The container treatment apparatus according to claim 1 ,
wherein
the container treatment apparatus comprises a monitoring device configured for monitoring the rotational movement of the containers.

7. The container treatment apparatus according to claim 6 ,
wherein
the monitoring device comprises a sensor device configured for detecting a magnetic flux, an image recording device and/or at least one coil.

8. The container treatment apparatus according to claim 4 ,
wherein
the drive device comprises a rotor coupled to the holding element, on which rotor a plurality of magnets is arranged, and a stator, on which a plurality of magnets or magnetic elements is also arranged.

9. The container treatment apparatus according to claim 4 ,
wherein
the drive device comprises a rotor coupled to the holding elements and a stator, wherein the rotor and/or the stator is made of or comprises a material having a high magnetic permeability, wherein said material is selected from a group of materials consisting of iron, mu-metal (NiFe), nanocrystalline metals and amorphous metals and/or the permeability number of the material is greater than 200.

10. The container treatment apparatus according to claim 9 ,
wherein
the stator is rectilinear and/or the magnets or magnetic elements of the stator extend along a straight direction.

11. The container treatment apparatus according to claim 8 ,
wherein
magnets or magnetic elements of the rotor and/or of the stator extend at least in sections obliquely with respect to a direction which is parallel to the axis of rotation of the holding element.

12. A method for treating containers, wherein the containers are transported along a predetermined transport path by a transport apparatus and wherein the transport apparatus has at least one transport device for transporting the containers and wherein at least one container treatment device treats the containers in a predetermined manner, wherein this transport device has a carrier, on which a plurality of holding elements are arranged which hold the containers,
wherein
the container treatment device treats the containers transported by the transport device and during this treatment the containers held by the holding elements are rotated at least at times with respect to a longitudinal direction of the containers, and a monitoring device monitors the rotary movement of the containers.

13. The method according to claim 12 ,
wherein
these holding elements are moved relative to the carrier in such a way that a distance between two containers immediately following one another on the transport path is changed.

14. The method according to claim 12 , wherein
the container treatment device treats the containers while the containers are transported along a substantially straight transport path section.

15. The method according to claim 12 ,
wherein
the rotary movement of the containers is smoothed and/or vibration damping is performed by eddy currents.
