Abstract

In a transport device for transporting containers, the transport device includes at least one transport unit movable along a curved track for transporting at least one container in response to a drive unit, the transport unit having a transport component mobile on the track and a receiver device for holding at least one container wherein the receiver device is constructed and arranged to be aligned in response and in relation to at least one movement force imparted upon the receiver device or the container as a result of movement of the transport unit.

Claims

1. A transport device for transporting containers, the transport device comprising:

at least one transport unit movable along a curved track for transporting at least one container in response to a drive unit, the transport unit having a transport component mobile on the track; and

,

a receiver device for holding at least one container, wherein the receiver device is constructed and arranged to be aligned in response and in relation to at least one movement force imparted upon the receiver device or the container as a result of movement of the transport unit, wherein the at least one movement force includes at least one of a centrifugal force in response to a transport movement on a curved track or an acceleration force in response to a change in transport speed, wherein the at least one container has an inertia or weight, and wherein the centrifugal force at least partly comprises the inertia or weight of the container or is a result of a vectorial sum of the centrifugal and acceleration forces.

2. A transport device according to claim 1, wherein the receiver device is constructed and arranged to align the body of the container while the container is deformable in a direction transverse to its longitudinal axis.

3. The transport device according to claim 1, wherein the receiver device can be swivelled about at least one first axis.

4. The transport device according to claim 3, wherein the receiver device can be swivelled about a second axis.

5. The transport device according to claim 1, wherein the receiving unit is constructed and arranged so that the alignment of the receiving unit substantially deflects the at least one movement force to a movement force directed along the longitudinal axis of the container.

6. A transport device according to claim 1, wherein the receiver device is constructed and arranged to automatically align the container.

7. A transport device according to claim 1, wherein the receiver device is constructed and arranged to be aligned by an alignment device.

8. A transport device according to claim 7, wherein the alignment device comprises at least one servo motor which is in contact with both the transport component and the receiver device.

9. A transport device according to claim 7, wherein the alignment device comprises sections that represent a control curve.

10. A transport device according to claim 1, wherein the receiver device is constructed and arranged to be aligned automatically in sections and guided in sections.

11. A transport device according to claim 1, wherein the transport device is a transport star.

12. A transport device according to claim 1, wherein the transport device is a blow wheel.

13. A transport device according to claim 1, wherein the transport device is a shuttle system.

14. A method for transporting containers comprising:

moving a transport unit for transporting at least one container along at least one curved track, wherein the transport unit moves in response to a drive unit, and wherein the transport unit has a transport component mobile on the track; and

,

holding the at least one container in a receiving unit; and

,

aligning the receiving unit in response at least one movement force imparted on the container or receiving unit, wherein the at least one movement force imparted on the container or receiving unit results from movement of the transport unit, wherein the at least one movement force includes at least one of a centrifugal force in response to a transport movement on the curved track or an acceleration force in response to a change in transport speed, wherein the at least one container has an inertia or weight, and wherein the centrifugal force at least partly comprises the inertia or weight of the container or is a result of a vectorial sum of the centrifugal and acceleration forces.

15. A transport device for transporting containers, the transport device comprising:

at least one transport unit movable along a curved track for transporting at least one container in response to a drive unit, the transport unit having a transport component mobile on the track; and

a receiver device for holding at least one container, wherein the receiver device is constructed and arranged to be aligned in response and in relation to at least one movement force imparted upon the receiver device or the container as a result of movement of the transport unit, wherein the force includes at least one of a centrifugal force in response to a transport movement on a curved track or an acceleration force in response to a change in transport speed, wherein the receiver device can be swivelled about at least one first axis, and wherein the receiver device can be swivelled about a second axis.
