1. A transport device, comprising:

at least one transport unit; and

a transport track comprising a plurality of transport segments arranged consecutively in the longitudinal direction to form a long stator linear motor, having a starting point and an ending point, along which the at least one transport unit can be moved in the longitudinal direction along a movement path predefined by the transport segments,

the plurality of transport segments comprising at least one curved transport segment having a curved movement path that is located in a two-dimensional plane, the two-dimensional plane defining a movement plane in which the at least one transport unit can be moved along an entirety of the transport track,

a transition segment including a continuous-flow conveyor having a longitudinal axis, adjoining the starting point or the ending point of the transport track in the longitudinal direction, for transporting the at least one transport unit in a direction of movement extending along the longitudinal axis,

wherein the continuous-flow conveyor is provided to move the at least one transport unit in the direction of movement at least sectionally in a conveying plane deviating from the movement plane of the transport track, and

wherein a steady transition between the movement plane of the transport track and the conveying plane of the continuous-flow conveyor is provided for a movement of the at least one transport unit without jerk in the region between the transport track and the transition segment.

2. The transport device according to claim 1 , wherein the conveying plane in the direction of the longitudinal axis of the continuous-flow conveyor is parallel to the movement plane at least sectionally.

3. The transport device according to claim 1 , wherein the conveying plane is rotated in the direction of movement at least sectionally by a certain rotational angle about the longitudinal axis of the continuous-flow conveyor.

4. The transport device according to claim 2 , wherein the longitudinal axis of the continuous-flow conveyor comprises at least one of a straight section or a curve section.

5. The transport device according to claim 4 , wherein the curve section is at least sectionally curved about an axis of curvature that is normal to the longitudinal axis.

6. The transport device according to claim 1 , wherein the longitudinal axis of the continuous-flow conveyor has a continuous course of curvature for the movement of the at least one transport unit without jerk along the continuous-flow conveyor.

7. The transport device according to claim 1 , wherein at least one further transition segment including a continuous-flow conveyor is provided adjoining the transition segment in the direction of movement.

8. The transport device according to claim 1 , wherein the starting point or the ending point of the transport track, or a starting point or an ending point of a further transport track adjoins the transition segment in the direction of movement.

9. The transport device according to claim 1 , wherein the continuous-flow conveyor comprises at least one holding device for holding the at least one transport unit on the continuous-flow conveyor in one of a force-fit or form-locked manner.

10. The transport device according to claim 9 , wherein the at least one holding device has ferromagnetic properties and cooperates with drive magnets of the at least one transport unit so as to hold the at least one transport unit in a force-fit manner.

11. The transport device according to claim 9 , wherein the at least one holding device comprises at least one receiving unit, which cooperates with at least one corresponding receiving element arranged on the at least one transport unit so as to hold the at least one transport unit on the continuous-flow conveyor in a form-locked manner.

12. The transport device according to claim 1 , wherein drive coils, which are arranged at a distance from one another in the longitudinal direction and of which each has a coil axis, are arranged on the transport segments, and

wherein the coil axes of all drive coils of all transport segments of the transport track being located in a shared two-dimensional coil plane that one of: corresponds to the movement plane of the transport track or is arranged parallel to the movement plane of the transport track.
