Abstract

A rail-led conveying device includes a conveying vehicle with at least three runner rollers for rolling conveying along a rail guide. Rotation planes of the at least three runner rollers are arranged at an angle of greater than 0° and smaller than 180° relative to one another. The associated conveying installation includes a plurality of such conveying devices as well as a corresponding rail guidance with a rail body. The rail body includes a rail body longitudinal section with three runner surfaces that are arranged on the outer periphery of the rail body and are for the at least three runner rollers of the conveying device. The surface normals of the three runner surfaces are arranged at an angle to one another of greater than 0° and smaller than 180°.

First claim

The invention claimed is:

1. A rail-led conveying vehicle with at least one first, second and third runner rollers that are each rotatably mounted about a pivot, for rolling conveying along a rail guidance, wherein:
rotation planes of the at least one first, second and third runner rollers are arranged at an angle of greater than 0° and smaller than 180° relative to one another,
the conveying vehicle comprises a first limb and a second limb, as well as a connection section connecting the first and second limbs to one another, wherein the first and second limbs and the connection section enclose a rail receiving space, and
at least two first runner rollers are arranged on the first limb one after the other in a conveying direction of the conveying vehicle, at least one second runner roller is arranged on the second limb, and at least one third runner roller is arranged on the connection section, in a rotatably mounted manner.

2. The conveying vehicle according to claim 1 , wherein the rail receiving space is open at one side and is for receiving a rail body, on which rail body the runner rollers can roll, and the at least one first, second and third runner rollers is arranged on the conveying vehicle such that their rotation planes intersect in the rail receiving space.

3. The conveying vehicle according to claim 1 , wherein a conveying element for holding a goods piece is arranged on the connection section.

4. The conveying vehicle according to claim 3 , wherein the conveying element is a holding clip.

5. The conveying vehicle according to claim 1 , wherein a contact element for creating a contact to a driver for the purpose of driving the conveying vehicle by way of the driver is arranged on the conveying vehicle.

6. A conveying installation comprising a plurality of rail-led conveying vehicles according to claim 1 , as well as a rail guidance with a rail body, wherein:
the rail body forms at least one rail body longitudinal section with at least three runner surfaces that are arranged on the outer periphery of the rail body and are for the at least one first, second and third runner rollers of the conveying vehicle, and the surface normals of the at least three runner surfaces are arranged at an angle of greater than 0° and smaller than 180° to one another.

7. The conveying installation according to claim 6 , wherein the rail body longitudinal section has a symmetrical cross section.

8. The conveying installation according to claim 6 , wherein the rail body longitudinal section is a hexagonal profile with six profile surfaces, and the at least three runner surfaces are formed by profile surfaces.

9. The conveying installation according to claim 8 , wherein adjacent profile surfaces in each case are arranged at an angle of 120° to one another.

10. The conveying installation according to claim 6 , wherein the at least three runner surfaces are formed by three profile surfaces that are arranged at angles to one another.

11. The conveying installation according to claim 6 , wherein the rail body comprises at least two rail body longitudinal sections with a different profile cross section.

12. The conveying installation according to claim 11 , wherein the rail body comprises a further rail body longitudinal section, which is designed as a round profile.

13. The conveying installation according to claim 6 , wherein the conveying vehicle laterally encompasses the rail body with the first and second limbs and the at least one first, second and third runner rollers are led in a rolling manner on the runner surfaces of the rail body.

14. The conveying installation according to claim 6 , wherein the conveying installation is a hanging conveyor, in which the piece goods at least in sections can be conveyed in a hanging manner.

15. The conveying installation according to claim 6 , wherein the conveying installation is a gravity conveyor, in which the piece goods can be conveyed along at least one conveying path section in a manner driven by gravity.

16. The conveying installation according to claim 6 , wherein the first and second limbs and the connection section of the conveying vehicle in the hanging conveying form a rail receiving space that is open to the top and is for receiving the rail body, and the connection section is arranged below the rail body.

17. The conveying installation according to claim 6 , wherein the rail body and the conveying vehicle are designed such that a torque acting on the conveying vehicle can be dissipated onto the rail body in a manner uniformly distributed over the at least one first, second and third runner rollers.
