Abstract

Roller pairs for processing a product, containing two grinding rollers, wherein at least one roller contains at least one sensor for obtaining measured values that characterize a state of at least one of the rollers, in particular a state of a circumferential surface. The sensor has a data connection to a data transmitter designed to transmit the measured values to a data receiver in an contact-free manner. Additionally, a measuring device for insertion into a receiving opening of a roller body of a roller of a roller pair, a product-processing installation, in particular a grinding installation containing at least one roller pair, a method of operating a product-processing installation, and a method of converting and/or upgrading at least one roller body are disclosed.

First claim

The invention claimed is:

1. A grinding roller pair for processing a product, containing a first grinding roller and a second grinding roller, wherein
said first grinding roller contains at least one co-rotating sensor which co-rotates, during operation, with the first grinding roller and which obtains measured values that characterize a state of a circumferential surface of at least said first grinding roller;
the co-rotating sensor has a data connection to at least one co-rotating first data transmitter co-rotating during operation with the first grinding roller, which co-rotating first data transmitter is capable of transmitting the measured values of the at least one co-rotating sensor to a first data receiver in a contact-free manner; and
the co-rotating first data transmitter is provided on or in the same first grinding roller as the co-rotating sensor having the data connection thereto;
wherein the first grinding roller comprises a grinding roller body with at least one receiving opening and at least one measuring device which is inserted into the receiving opening, which measuring device contains at least one of the co-rotating sensors;
at least one of the at least one receiving openings extends parallel to a rotation axis of the grinding roller body and along the entire length of the grinding roller body and is arranged in an outer area of the grinding roller body; and
at least one of the co-rotating sensors is selected from the group consisting of a temperature sensor, a pressure sensor, a force sensor, a vibration sensor, a rotational speed sensor, a rotational acceleration sensor, and a gyroscopic sensor.

2. The grinding roller pair according to claim 1 , wherein the co-rotating first data transmitter is arranged on an end face of the first grinding roller.

3. The grinding roller pair according to claim 1 , wherein a plurality of said co-rotating sensors are present which have a data connection to the at least one co-rotating first data transmitter.

4. The grinding roller pair according to claim 1 , wherein the first grinding roller contains at least one multiplexer which is capable of alternately transmitting the measured values obtained by the co-rotating sensors to the co-rotating first data transmitter.

5. The grinding roller pair according to claim 1 , wherein the first grinding roller contains at least one signal converter for converting the measured values obtained by the co-rotating sensor.

6. The grinding roller pair according to claim 1 , wherein the first grinding roller contains at least one power receiver.

7. The grinding roller pair according to claim 1 , wherein said first grinding roller contains at least one printed circuit board on which there is provided at least one component selected from the group consisting of the co-rotating sensor, the at least one multiplexer, the at least one signal converter, the at least one co-rotating first data transmitter, the at least one power receiver, the at least one power generator.

8. The grinding roller pair according to claim 1 , wherein at least one of the at least one receiving openings is formed in a circumferential surface of the grinding roller body.

9. The grinding roller pair according to claim 8 , wherein said at least one measuring device is a bolt with a thread, and the receiving opening formed in a circumferential surface of the grinding roller body has a mating thread into which the thread of the bolt is screwed, during operation.

10. The grinding roller pair according to claim 1 , wherein said at least one measuring device has at least one second data transmitter and at least one second data receiver, wherein said second data transmitter and said second data receiver are capable of transmitting the measurement data obtained by the co-rotating sensor in a contact-free manner from the second data transmitter to the second data receiver.

11. A measuring device for insertion into the receiving opening of the grinding roller body of the first grinding roller of the grinding roller pair according to claim 1 , for processing a product, which measuring device has a printed circuit board and at least one of the co-rotating sensors.

12. A product-processing installation containing at least one grinding roller pair according to claim 1 .

13. A method for operating a product-processing installation according to claim 12 , comprising a step in which measured values transmitted by the co-rotating first data transmitter of said first grinding roller of the grinding roller pair are received by the first data receiver of the product-processing installation.

14. A method for converting or upgrading at least one grinding roller body of a grinding roller pair for processing a product, containing a step in which the measuring device according to claim 11 is inserted into a receiving opening in the grinding roller body which extends parallel to a rotation axis of the grinding roller body.

15. The measuring device according to claim 11 , wherein the measuring device is rod-shaped and has a longitudinal axis along which a plurality of sensors are arranged.

16. The grinding roller pair according to claim 1 , wherein the first grinding roller contains at least one power generator for powering the co-rotating sensor.

17. The grinding roller pair according to claim 10 , wherein said second data transmitter and said second data receiver are capable of transmitting the measurement data obtained by the co-rotating sensor in a contact-free manner from the second data transmitter to the second further data receiver through an interior cavity of the grinding roller body.
