Abstract

To provide a code carrier device for mounting on a material flow object, with a code carrier, which comprises a memory for storing an individual identification and a transmitter device for transmitting the identification, so that the identification can be contactlessly read by a receiver when the transmitter device and receiver are in a specific relative positional range in relation to each other, with which code carrier device the identification can be read in a simple way, it is proposed that the transmitter device has a first transmitting face and at least a second transmitting face, being transversely thereto, by means of which the identification can in each case be read, the readability being determined by the relative position between a receiver and a transmitting area.

Claims

1. A code carrier device for mounting on a material flow object, comprising

a code carrier having a memory for storing an individual identification;

and

a transmitter device for transmitting the identification, so that the identification is contactlessly readable by a receiver when the transmitter device and receiver are in a specific relative positional range in relation to each other;

wherein the transmitter device has a first transmitting face and at least a second transmitting face being arranged transversely to the first transmitting face, by means of which transmitting faces said identification is readable, respectively, the readability being determined by the relative position between a receiver and a transmitting face.

2. The code carrier device as claimed in claim 1, wherein a specific first energy flux density vector of the radiation, which is related to the first transmitting face, and a second energy flux density vector, which is related to the second transmitting face and which is in the same relationship with the second transmitting face and as the first energy flux density vector is with the first transmitting face, are transversely in relation to each other.

3. The code carrier device as claimed in claim 1, wherein a transmitter of the transmitter device which provides a transmitting face comprises a coil.

4. The code carrier device as claimed in claim 3, wherein a transmitter comprises a toroidal coil.

5. The code carrier device as claimed in claim 1, wherein an energy flux density associated with a transmitting face is node-free.

6. The code carrier device as claimed in claim 1, wherein the transmitter device is arranged in a housing.

7. The code carrier device as claimed in claim 6, wherein the first transmitting face is arranged with respect to a first lateral face of the housing and the second transmitting face is arranged with respect to a second lateral face, which is transversely in relation to the first lateral face.

8. The code carrier device as claimed in claim 7, wherein a transmitting face is oriented substantially parallel to a lateral face.

9. The code carrier device as claimed in claim 7, wherein the first lateral face and the second lateral face have a common edge.

10. The code carrier device as claimed in claim 1, wherein transmitting faces being transversely in relation to each other are formed by different transmitters of the transmitter device.

11. The code carrier device as claimed in claim 1, wherein, to provide the transmitting faces, the transmitter device comprises coils connected in parallel.

12. The code carrier device as claimed in claim 11, wherein a capacitor is connected in series with the coils.

13. The code carrier device as claimed in claim 1, wherein a housing of the code carrier device is such a way and mounted on the material flow object in such a way and the transmitting faces are oriented in such a way that the transmitting faces are arranged substantially in the possible directions of movement of the material flow object.

14. The code carrier device as claimed in claim 1, wherein the transversely arranged transmitting faces of the transmitter device are provided by a single transmitter.

15. The code carrier device as claimed in claim 14, wherein the transmitter comprises a bar coil, which is arranged in such a way that it has the same radiation characteristic transversely in relation to a first direction of movement of the material flow object as transversely in relation to a second direction of movement of the material flow object, the first and second directions of movement being transverse to each other.

16. The code carrier device as claimed in claim 1, wherein a relative position between the transmitter device and the receiver for reading the identification is determined by a linear spacing and a transverse spacing between a transmitting face and the receiver.

17. The code carrier device as claimed in claim 1, wherein the transmitter device is a passive transmitter device which is actuatable by a receiver.

18. The code carrier device as claimed in claim 17, wherein the code carrier is suppliable with energy via an electromagnetic field coupled in by a receiver.

19. The code carrier device as claimed in claim 1, wherein the code carrier is writable by means of a receiver.

20. The code carrier device as claimed in claim 19, wherein a transmitting face provides a receiving face for the writing signals for writing on the code carrier.

21. The code carrier device as claimed in claim 1, wherein a first transmitting face, a second transmitting face and a third transmitting face, which respectively are transversely in relation to one another, are provided.

22. The code carrier device as claimed in claim 1, wherein, to provide the transmitting faces, the transmitter device comprises coils connected in series.

23. The code carrier device as claimed in claim 22, wherein a capacitor is connected in series with the coils.
