Abstract

The invention relates to an in-house track-bound transporting system with self-propelling carriages that move on rails. The system has stoppers to prevent said carriages from crossing over open rail ends or track borders, and the system is provided with stops. The stoppers collide with the stops in order to prevent a crossing-over, said stops having first and second fixed stop elements. The stoppers can be moved between a first crossing-over position and a second crossing-over position such that the first stop elements can be crossed over in the first crossing-over position of the stoppers, and the second stop elements can be crossed over in the second crossing-over position of the stoppers, wherein the first stop elements cannot be crossed over in the second crossing-over position of the stoppers, and the second stop elements cannot be crossed over in the first crossing-over position of the stoppers.

Claims

1. In-plant rail-bound transport system having shuttles which travel on rails, wherein the system comprises:

stops and stop bars that interact with each other to secure against the shuttles overrunning of open rail ends or boundaries of travel paths, wherein the stop bars engage the stops to prevent overrunning of the open rail ends or boundaries of travel paths;

wherein the stops have first and second immoveable stop elements and wherein the stop bars are able to move between a first overrunning position and a second overrunning position, wherein the first stop elements can be overrun in the first overrunning position of the stop bars, the second stop elements can be overrun in the second overrunning position of the stop bars; and

wherein the first stop elements cannot be overrun in the second overrunning position of the stop bars and that the second stop elements cannot be overrun in the first overrunning position of the stop bars.

2. Transport system as claimed in claim 1, wherein the stop bars are disposed on the vehicles and the stops are disposed on the rails.

3. Transport system as claimed in claim 1 wherein the first and second stop elements are spaced apart from each other in a longitudinal direction of the rail path.

4. Transport system as claimed in claim 1 wherein the stop bars are formed as driven stops which can move between the first overrunning position and the second overrunning position.

5. Transport system as claimed in claim 4, wherein the driven stops can move about a pivot axis oriented in a travel direction of the shuffles.

6. Transport system as claimed in claim 4 wherein the driven stops can move between the first overrunning position and a second overrunning position by at least 20°

and at most 90°

about a pivot axis oriented in a travel direction of the shuttles.

7. Transport system as claimed in claim 1 wherein the stop bars are formed as spring-loaded stops on both sides in a travel direction of the shuttles.

8. Transport system as claimed in claim 1 wherein the stop bars are provided with a brake lining which interacts with an inclined braking surface on one of the stop elements to brake the shuttle in the corresponding non-overrunning position.

9. Transport system as claimed in claim 8, wherein the inclined braking surface is disposed on the first stop element and extends approximately vertically and is formed by an inclined plane which increases laterally in a direction of travel of the shuttle towards an end of the rail.

10. Transport system as claimed in claim 9 wherein the rails are formed as essentially C-shaped profiled rails defining an opening in a profile of the rail wherein the opening in the profile of the rail is disposed inwards and downwards in such a way that the stop bars disposed on the vehicles can protrude into the profile of the rail and interact with stop elements disposed inside the profile of the rail.

11. Transport system as claimed in claim 2 wherein the first and second stop elements are spaced apart from each other in a longitudinal direction of the rail path.

12. Transport system as claimed in claim 11 wherein the stop bars are formed as driven stops which can move between the first overrunning position and the second overrunning position.

13. Transport system as claimed in claim 12 wherein the driven stops can move about a pivot axis oriented in a travel direction of the shuttles.

14. Transport system as claimed in claim 13 wherein the driven stops can move between the first overrunning position and a second overrunning position by at least 20°

and at most 90°

about a pivot axis oriented in the travel direction of the shuttles.

15. Transport system as claimed in claim 12 wherein the driven stops can move between the first overrunning position and a second overrunning position by at least 20°

and at most 90°

about a pivot axis oriented in a travel direction of the shuttles.

16. Transport system as claimed in claim 5 wherein the driven stops can move between the first overrunning position and a second overrunning position by at least 20°

and at most 90°

about a pivot axis oriented in the travel direction of the shuttles.

17. Transport system as claimed in claim 2 wherein the stop bars are formed as driven stops which can move between the first overrunning position and the second overrunning position.

18. Transport system as claimed in claim 17 wherein the driven stops can move about a pivot axis oriented in a travel direction of the shuttles.

19. Transport system as claimed in claim 18 wherein the driven stops can move between the first overrunning position and a second overrunning position by at least 20°

and at most 90°

about a pivot axis oriented in the travel direction of the shuttles.

20. Transport system as claimed in claim 17 wherein the driven stops can move between the first overrunning position and a second overrunning position by at least 20°

and at most 90°

about a pivot axis oriented in a travel direction of the shuttles.

21. Transport system as claimed in claim 2 wherein the rails are formed as essentially C-shaped profiled rails defining an opening in a profile of the rail wherein the opening in the profile of the rail is disposed inwards and downwards in such a way that the stop bars disposed on the vehicles can protrude into the profile of the rail and interact with stop elements disposed inside the profile of the rail.
