Abstract

A laboratory sample distribution system is presented. The laboratory sample distribution system comprises an optical inspection device adapted to optically inspect items that need to be optically inspected, at least one mirror device, a driver adapted to move the items to be optically inspected and to move the at least one mirror device, and a control device configured to move an item to be optically inspected relative to the optical inspection device by controlling the driver such that a field of view of the optical inspection device is extended.

First claim

We claim:

1. A laboratory sample distribution system, the laboratory sample distribution system comprising:
a transport plane;
an optical inspection device adapted to optically inspect items that need to be optically inspected;
at least one mirror device used to view portions of the items that need to be optically inspected that would not be visible without the at least one mirror device, wherein the at least one mirror device comprises a base portion comprising a bottom surface for moving over the transport plane of the laboratory sample distribution system and a mirror, wherein the mirror comprises a first mirror segment and a second mirror segment and the base portion comprises a first base portion segment holding the first mirror segment and a second base portion segment holding the second mirror segment, wherein the mirror device comprises a joint connecting the first base portion segment to the second base portion segment such that the first base portion segment and/or the second base portion segment are rotatable around the joint and wherein the first base portion segment and the second base portion segment are configured to be moved on the transport plane by the driver;
a driver adapted to move the items that need to be optically inspected independently from the at least one mirror device on the transport plane; and
a control device configured to move the items that needs to be optically inspected relative to the optical inspection device by controlling the driver.

2. The laboratory sample distribution system according to claim 1 , wherein the mirror is oriented perpendicular to the bottom surface.

3. The laboratory sample distribution system according to claim 1 , wherein the mirror is an angled mirror with respect to an axis perpendicular to the bottom surface.

4. The laboratory sample distribution system according to claim 1 , further comprising,
a number of sample container carriers adapted to carry a respective sample container, wherein the sample containers are the items that need to be optically inspected.

5. The laboratory sample distribution system according to claim 4 , wherein the driver is adapted to move the sample container carriers and the mirror device on the transport plane.

6. The laboratory sample distribution system according to claim 4 , wherein the control device is configured to control the movement of the sample container carriers on top of the transport plane by controlling the driver such that the sample container carriers move along corresponding transport paths and is configured to control the movement of the mirror device on top of the transport plane by controlling the driver such that the mirror device moves to a mirror position on the transport plane.

7. The laboratory sample distribution system according to claim 4 , further comprising,
a scanning device forming the optical inspection device configured to scan a barcode or other information placed on a sample container carried by a sample container carrier that is placed at a scanning position on the transport plane, wherein the scanning position is located on the transport plane between the scanning device and a mirror position.

8. The laboratory sample distribution system according to claim 1 , the mirror device comprises a magnetically active device for interaction with a magnetic field generated by the driver formed as electromagnetic actuators such that a magnetic drive force is applied to the mirror device.

9. The laboratory sample distribution system according to claim 1 , wherein the control device is configured to drive the mirror device such that it is rotated on the transport plane.

10. The laboratory sample distribution system according to claim 7 , wherein the scanning device and/or the mirror is/are configured to allow a 360° view of the scanning device on the sample container at the scanning position.

11. The laboratory sample distribution system according to claim 7 , wherein the control device is configured to move the number of sample container carriers, each carrying a sample container successively to and away from the scanning position.

12. The laboratory sample distribution system according to claim 4 , wherein the driver is formed as electromagnetic actuators located below the transport plane and controllable by the control device and the sample container carriers each comprise a magnetically active device for interaction with a magnetic field generated by the electromagnetic actuators such that a magnetic drive force is applied to the sample container carriers.

13. A laboratory automation system, the laboratory automation system comprising:
a number of laboratory stations; and
a laboratory sample distribution system according to claim 1 .

14. A laboratory sample distribution system, the laboratory sample distribution system comprising:
a transport plane;
an optical inspection device adapted to optically inspect items that need to be optically inspected;
at least one mirror device used to view portions of the items that need to be optically inspected that would not be visible without the at least one mirror device, wherein the at least one mirror device comprises a base portion comprising a bottom surface for moving over the transport plane of the laboratory sample distribution system and a mirror;
a driver adapted to move the items that need to be optically inspected independently from the at least one mirror device on the transport plane, wherein the driver is adapted to move the sample container carriers and the mirror device on the transport plane;
a number of sample container carriers adapted to carry a sample container, wherein the sample containers are the items that need to be optically inspected; and
a control device configured to move the items that needs to be optically inspected relative to the optical inspection device by controlling the driver, wherein the control device is configured to control the movement of the sample container carriers on top of the transport plane by controlling the driver such that the sample container carriers move along corresponding transport paths and is configured to control the movement of the mirror device on top of the transport plane by controlling the driver such that the mirror device moves to a mirror position on the transport plane.
