Abstract

In a method of distributing packages according to addresses, headings or the like applied to their surfaces by means of a separating and conveying device, it is provided that along a conveying path all surface portions of each previously separated package are scanned optically, for each package images are obtained from the surface portions of the package and, for further evaluation, the images are displayed simultaneously or approximately simultaneously. For each package, one or a plurality of the images are selected, and each selected image is assigned a sorting information for the distribution of the package corresponding to that image.

Claims

1. A method of distributing multisurface packages by a separating and conveying device according to an address applied to a package surface, comprising the following steps:

(a) individually conveying the packages in a transporting direction along a conveying path;

(b) optically scanning each surface of each package, including an optical scanning of an underside of each package through a gap in said conveying path;

said scanning step including rough-scanning at least some of the package surfaces;

(c) based on step (b), obtaining, at least approximately simultaneously, an image of all package surfaces of each package on a single monitor having six partial image regions;

(d) selecting, for each package, a package surface based on all surface images obtained in step (c);

(e) fine-scanning the package surface selected in step (d);

(f) based on step (e), obtaining an at least partial image of the selected surface; and

(g) assigning to the image of the selected package surface a sorting information for distributing the package corresponding to the image.

2. A method according to claim 1, wherein the images are displayed on one or a plurality of monitors for joint evaluation.

3. A method according to claim 1, wherein in the first step (b), a linear camera with high resolution scans the underside of the package through the gap in the conveying path.

4. A method according to claim 1, wherein still pictures of the rough scanning are employed.

5. A method according to claim 1, wherein the images from the rough scanning are supplied to an automatic character recognition device which evaluates the images and selects a surface portion for fine scanning only if the images obtained by rough scanning are rejected.

6. A method according to claim 1, wherein the image of the finely scanned surface is fed to an automatic character recognition device.

7. A method according to claim 6, wherein images rejected by the automatic character recognition device are fed to a video coding devices for the input of correct addresses.

8. A method according to claim 7, characterized in that sorting means which are electrically connected with the character recognition device sort the packages as a function of their addresses.

9. A method according to claim 7, wherein a code is associated with the address and is applied to the packages.

10. A method according to claim 1, wherein moving pictures of the rough scanning are used.

11. An apparatus for recognizing an address on a surface of multisurface packages;

comprising

(a) a conveyor for consecutively advancing the packages along a conveying path;

(b) a gap provided in the conveying path over which the packages are moved;

(c) optical scanning means for optically scanning all surfaces of each package;

said optical scanning means including means for scanning an underside of each package through said gap;

said optical scanning means including means for rough-scanning at least some of the package surfaces;

(d) displaying means for at least approximately simultaneously displaying images of all surfaces of each package;

said displaying means being formed of a single monitor having six partial image regions; and

(e) means for fine-scanning a region of a selected image and for obtaining an image of the region with a predetermined resolution.

12. An apparatus according to claim 11, said optical scanning means comprising six cameras for optically scanning all surface portions.

13. An apparatus according to claim 11, said means for scanning an underside comprising a linear camera with high resolution.

14. An apparatus according to claim 11, further in that automatic character recognition means are for the association of distribution codes with the addresses.

15. An apparatus according to claim 11, further comprising a video coding device for assigning distribution codes to the addresses.
