Claims

1. A conveying member with an actuating device for a conveyor, comprising:
a conveying element that forms a main surface, and at least one roller mechanism with at least one roller that comprises a physical roller pivot, wherein the roller mechanism comprises a roller holder, the roller pivot is fastened to the roller holder, the roller holder can interact with the actuating device, the roller holder is arranged on the conveying element and the roller holder is designed such that the roller pivot is movable by the actuating device relative to the main surface of the conveying element at least between a first position and a second position which is spatially different than the first position with regard to a distance to the main surface,
wherein in the first as well as in the second position of the roller pivot, the roller projects at least partly beyond the main surface of the conveying element and, in the first position of the roller pivot, the roller is in an arrested position, and in the second position of the roller pivot, the roller is in a freewheel position, wherein in the arrested position, the roller is arrested with respect to a rotation relative to the main surface and in the freewheel position the roller is freely rotating.
2. The conveying member with an actuating device according to claim 1, wherein the roller holder is designed such that in a drive position of the roller, the roller is driven in the roller holder and at least partly projects beyond the main surface of the conveying element.
3. The conveying member with an actuating device according to claim 1, wherein the actuating device comprises at least one rail that is spatially fixed in at least one position with respect to the conveyor, the at least one rail supporting the roller pivot and pressing the roller pivot relative to the conveying element.
4. The conveying member with an actuating device according to claim 1, wherein the roller holder includes a guide for a translatory displacement of the roller pivot between the first and second positions.
5. The conveying member with an actuating device according to claim 4, wherein the translatory displacement is aligned essentially orthogonally to the main surface.
6. The conveying member with an actuating device according to claim 1, wherein the roller mechanism comprises an arresting device and the roller in the arrested position lies on the arresting device in the direction of gravity.
7. The conveying member with an actuating device according to claim 6, wherein the arresting device is designed as a braking frame that comprises an opening corresponding to a contour of the roller, wherein the roller in the arrested position lies on the braking frame in a manner reaching into the opening in the direction of gravity and by way of this projects partly into the opening in the direction of gravity.
8. The conveying member with an actuating device according to claim 7, wherein the braking frame is rigidly fastened to the roller mechanism and is designed in a stationary manner with respect to the conveying element.
9. The conveying member with an actuating device according to claim 1, wherein the roller holder is designed such that a spatial position of the roller in the arrested position lies further to the bottom than in the freewheel position and the roller in the arrested position lies furthest to the bottom compared to all other positions of the roller.
10. The conveying member with an actuating device according to claim 1, wherein the roller mechanism comprises an adjusting mechanism which is designed such that the roller is capable of assuming different spatial lateral positions transversely to the conveying direction of the conveyor.
11. The conveying member comprising a conveying member with an actuating device according to claim 1, wherein the roller pivot can be vertically moved relative to the main surface of the conveying element between at least two positions which are spatially different from one another, by way of the actuating device.
12. The conveying member according to claim 11, wherein the arrangement and design of the actuating device is such that in the freewheel position of the roller, the actuating device directly or indirectly supports the roller pivot counter to the direction of gravity and the roller is freely rotating thereby.
13. The conveying member according to claim 11, wherein the conveying member comprises an upper stop for the roller pivot, said upper stop being designed and arranged in a manner such that in the freewheel position, the actuating device is capable of directly or indirectly pressing the roller pivot against the upper stop counter to the direction of gravity.
14. The conveying member according to claim 1, wherein, in the drive position, the running surface of the roller can be in frictional contact with a rolling guide, wherein the rolling guide in particular is encompassed by the actuating device.
15. The conveying member according to claim 11, wherein the conveyor is designed as one of a plate chain conveyor and a mat chain conveyor.
