Abstract

In a mail processing system that delivers articles to delivery locations a first transport vehicle at a first loading point is loaded with a first article, and guided along a first delivery path to a first delivery location. A second transport vehicle at a second loading point is loaded with a second article, and guided along a second delivery path to a second delivery location. Depending on a determination of whether the first and second transport vehicles deliver the first and second articles to the respective first and second delivery locations, the method returns an empty transport vehicle to the nearest one of the loading points and bypasses one of the first and second loading points for a still loaded transport vehicle. This allows to minimize the number of transport vehicles within the system.

Claims

1. A method of delivering articles to predetermined delivery locations within a mail processing system, comprising:

loading, a first transport vehicle at a first loading point with a first article;

guiding the first transport vehicle along a first delivery path towards a first delivery location;

loading a second transport vehicle at a second loading point with a second article;

guiding the second transport vehicle along a second delivery path towards a second delivery location;

determining if the first transport vehicle delivers the first article at the first delivery location and if the second transport vehicle delivers the second article at the second delivery location;

guiding the first transport vehicle to the second loading point if it delivered the first article at the first delivery location, and the second transport vehicle to the first loading point if it delivered the second article at the second delivery location, and

guiding the first transport vehicle to the second delivery location if it did not deliver the first article at the first delivery location, and the second transport vehicle to the first delivery location if it did not deliver the second article at the second delivery location.

2. The method of claim 1, wherein the first and second loading points are at different locations within the mail processing system.

3. The method of claim 1, wherein guiding the first transport vehicle to the second delivery location if it did not deliver the first article at the first delivery location includes by-passing the second loading point, and wherein guiding the second transport vehicle to the first delivery location if it did not deliver the second article at the second delivery location includes by-passing the first loading point.

4. The method of claim 1, further comprising vertically diverting the first and second transport vehicles.

5. The method of claim 1, further comprising vertically merging the first and second transport vehicles.

6. The method of claim 1, further comprising re-circling the first and second transport vehicles if an article cannot be delivered.

7. The method of claim 1, further comprising sorting exception articles using an exception line.

8. A method of delivering articles to predetermined delivery locations within a mail processing system, comprising:

inserting a first article at a first loading point into a first delivery path, and a second article at a second loading point into a second delivery path;

transporting the first and second articles towards the first and second delivery locations, respectively;

by-passing the first delivery location if the first delivery location does not include a destination address that corresponds to an address of the first article; and

by-passing the second delivery location if the second delivery location does not include that corresponds to an address of the second article.

9. The method of claim 8, further comprising transporting the first article to the second delivery location after by-passing the first delivery location, and the second article to the first delivery location after by-passing the second delivery location.

10. The method of claim 8, further comprising by-passing the first loading point after by-passing the second delivery location, and by-passing the second loading point after by-passing the first delivery location.
