Abstract

Disclosed is an object feeder system configured for arrangement in a three dimensional scanner, the system comprising: an object feeder scanning plate assembly comprising a number of tracks, wherein each track adapted to hold at least one object holder, wherein said tracks are configured to extend within the plate assembly from a parking area towards a scanning area, and where each object holder is configured for retaining an object to be scanned in the scanner for obtaining a three dimensional representation of the object, and wherein the object feeder system further comprises means for moving the at least one object holder in the at least one track.

First claim

The invention claimed is:

1. An object feeder system configured for arrangement in a three dimensional scanner, the system comprising:
an object feeder scanning plate assembly comprising a number of tracks, wherein each track is adapted to hold at least one object holder, wherein said tracks are configured to extend within the plate assembly from a parking area towards a scanning area, and where each of the at least one object holder is configured for retaining an object to be scanned in the scanner for obtaining a three dimensional representation of the object; and
means for moving the at least one object holder in its track;
wherein the plate assembly comprises a fixture plate and a core plate arranged substantially coaxially relative to each other, where the fixture plate has an opening in its center in which the core plate is arranged; and
wherein the fixture plate comprises an outer track portion of each of the tracks, and where the core plate comprises one inner track portion, which is configured to align with each of the outer track portions in turn, such that one complete track from the outer edge of the plate assembly to the centre of the plate assembly can be arranged at a time.

2. The object feeder system according to claim 1 , wherein the parking area is located at an outer edge of the plate assembly.

3. The object feeder system according to claim 1 , wherein the scanning area is substantially at the centre of the plate assembly.

4. The object feeder system according to claim 1 , wherein the object feeder scanning plate assembly further comprises a base plate arranged as a base for both the fixture plate and the core plate, and where the base plate is adapted to be mounted on an axis in a 3D scanner.

5. The object feeder system according to claim 4 , wherein each outer track portion in the fixture plate comprises a recess on the side of the fixture plate facing the base plate.

6. The object feeder system according to claim 4 , wherein the inner track portion in the core plate comprises a recess on the side of the core plate facing the base plate.

7. The object feeder system according to claim 4 , wherein the base plate comprises a magnet including a permanent magnet or an electromagnet.

8. The object feeder system according to claim 1 , wherein the at least one object holder is secured in the tracks, so that the at least one object holder cannot be removed from the tracks and thereby from the plate assembly, when the plate assembly and the at least one object holder are assembled and configured for normal use.

9. The object feeder system according to claim 1 , wherein the plate assembly is adapted to comprise a number of object holders in such a manner that there remains a free space on the plate assembly, where there are no tracks and therefore never any object holders, such that there is visual access to the scanning area across the part of the plate where there are no tracks and no object holders.

10. The object feeder system according to claim 1 , wherein the at least one object holder is made of a magnetic material.

11. The object feeder system according to claim 1 , wherein the means for moving the at least one object holder comprises an object feeder arm assembly.

12. The object feeder system according to claim 11 , wherein the object feeder arm assembly comprises a first arm configured for moving the at least one object holder one at a time.

13. The object feeder system according to claim 12 , wherein the first arm comprises a head member comprising an electromagnet, which is adapted to be turned on when the first arm starts contacting one of the at least one object holder to move it from the scanning area to the parking area of the plate assembly.

14. The object feeder system according to claim 11 , wherein the arm assembly further comprises a second arm configured for locking the fixture plate in a specific position.

15. The object feeder system according to claim 1 , wherein the object feeder system is configured for removable insertion into the scanner.

16. A three dimensional scanner configured for insertion of the object feeder system according to claim 1 .

17. The object feeder system according to claim 1 , wherein each of the tracks comprises a groove formed in the object feeder scanning plate.
