Abstract

According to the invention, individually controlled movable workpiece carriers for the components are provided, or in addition to a work conveyor path for the workpiece carriers, a path for temporary parking is provided for a separate multitude of workpiece carriers.

First claim

The invention claimed is:

1. A transport system comprising:
a multitude of workpiece carriers, wherein the multitude of workpiece carriers are positioned along a working path associated with a rail;
a plurality of output means connected to the rail at respective locations and to provide a respective output path for each workpiece carrier of the multitude of workpiece carriers out of the working path into a respective non-working path, wherein along each non-working path at least one other workpiece carrier is positioned;
a plurality of input means connected to the rail at respective locations different from the respective locations at which the plurality of output means are connected and to provide a respective input path for each other workpiece carrier out of the respective non-working path into the working path; and
a controller to:
drive a respective other workpiece carrier along the respective non-working path and an associated input path into the working path; and
drive at least one workpiece carrier of the multitude of workpiece carriers along the working path and along an associated output path into the respective non-working path.

2. The transport system according to claim 1 , wherein each of the plurality of output means and each of the plurality of input means comprise a rail switch.

3. The transport system according to claim 1 , wherein one of the plurality of output means provides a given workpiece carrier of the multitude of workpiece carriers access to a workpiece carrier parking path.

4. The transport system according to claim 3 , wherein the workpiece carrier parking path corresponds to a dead end.

5. The transport system according to claim 3 , wherein the workpiece carrier parking path is associated with a corresponding bypass.

6. The transport system according to claim 1 , wherein each of the multitude of workpiece carriers comprise a holding area and each workpiece carrier positioned along a corresponding non-working path comprises a holding area, wherein each holding area of the multitude of workpiece carriers is one of different and same from each workpiece carrier positioned along the corresponding non-working path.

7. The transport system according to claim 1 , wherein the controller is to individually control a position of each workpiece carrier of the multitude of workpiece carriers and each other workpiece carrier positioned along a corresponding non-working path.

8. The transport system according to claim 7 , wherein the controller is to continuously assign adjustable stopping points to each workpiece carrier of the multitude of workpiece carriers.

9. The transport system according to claim 7 , wherein the controller is to monitor positions of each workpiece carrier of the multitude of workpiece carriers and to maintain a cleared safety corridor around each workpiece carrier of the multitude of workpiece carriers, wherein the size of the safety corridor is based on a motion speed.

10. The transport system according to claim 7 , wherein the controller is to detect when a given workpiece carrier is taken out of a given path and/or inserted into the given path, and to one of deactivate and activate a drive associated with the given workpiece carrier.

11. The transport system according to claim 1 , wherein a given workpiece carrier is designed to be one of removable from and insertable into the given path without destruction, wherein the given path comprises one of the working-path and the non-working path.

12. The transport system according to claim 1 , wherein each workpiece carrier of the multitude of workpiece carriers is associated with a magnetic drive, the magnetic drive being controllable by the controller to adjust a position of a respective workpiece carrier of the multitude of workpiece carriers.

13. The transport system according to claim 1 , wherein a device for arranging a carrier adapter on a holding area is provided.

14. The transport system according to claim 1 ,
wherein each of the plurality of output means is connected to a respective bypass associated with a corresponding non-working path, and
wherein each of the plurality of input means is connected to the respective bypass associated with the corresponding non-working path.

15. The transport system according to claim 14 , further comprising:
a camera one of disposed above and below the working path associated with the rail; and
image analysis means to recognize a type of workpiece carrier of at least one workpiece carrier of the multitude of workpiece carriers positioned along the working path.

16. The transport system according to claim 1 ,
wherein the working path corresponds to a plurality of working paths, and
wherein each workpiece carrier of the multitude of workpiece carriers is configured to move along a respective working path of the plurality of working paths.

17. The transport system according to claim 1 , wherein each of the plurality of input means and the plurality of output means are connected to a respective bypass associated with a corresponding non-working path.

18. The transport system according to claim 17 , wherein each bypass comprises a rail.

19. The transport system according to claim 18 , wherein the rail is circulating rail.

20. The transport system according to claim 1 , wherein the controller sets a given corridor around each workpiece carrier of the multitude of workpiece carriers.

21. The transport system according to claim 20 , wherein a size of the given corridor for each workpiece carrier of the multitude of workpiece carriers is based on a given position associated with each workpiece of the multitude of workpiece carriers.

22. The transport system according to claim 20 , wherein the size of the given corridor of the at least one workpiece carrier of the multitude of workpiece carriers is greater when the at least one workpiece carrier is positioned along the working path at a given instance of time relative to when the at least one workpiece carrier is positioned along the respective non-working path at another instance of time.
