Abstract

A scraping device for a rotary press comprising at least one scraping element for scraping pellets located on a die plate of the rotary press to an outlet, wherein the at least one scraping element has at least one identification and/or position unit having identification and/or position data relating to the at least one scraping element, and wherein the scraping device further comprises a read and/or write unit which is designed to communicate with the at least one identification and/or position unit in order to read the identification and/or position data from the at least one identification and/or position unit. The invention also relates to a rotary press and a corresponding method.

First claim

The invention claimed is:

1. A scraping device for a rotary press for scraping pellets ( 66 ) located on a die plate ( 24 ) of the rotary press, comprising a plurality of scraping elements ( 62 ), the plurality of scraping elements differing in their size and only one of which is used at a time during operation, characterized in that the plurality of scraping elements ( 62 ) have at least one identification and position unit ( 84 ) having identification and position data relating to the one of the plurality of scraping elements ( 62 ) which is used at a time during operation and which is located at a predetermined stationary position above the die plate, the scraping device further comprises a read and write unit ( 86 ) which is designed to communicate with the at least one identification and position unit ( 84 ) in order to read the identification and position data from the at least one identification and position unit ( 84 ), the at least one identification and position unit ( 84 ) comprising at least one position sensor, which detects the position of the one scraping element ( 62 ) used at a time during operation and which is located at a predetermined stationary position above the die plate ( 24 ) and the scraping device further including position means by which the one scraping element ( 62 ) located above the die plate can be automatically brought into a position above the die plate in dependence upon a position detected by the at least one position sensor.

2. The scraping device according to claim 1 , characterized in that the at least one identification and position unit ( 84 ) comprises at least one transmitting and receiving unit, and the read and write unit ( 86 ) also comprises a transmitting and receiving unit by means of which the read and write unit ( 86 ) for reading out the identification and position data wirelessly communicates with the at least one transmitting and receiving unit of the at least one identification and position unit ( 84 ).

3. The scraping device according to claim 1 , characterized in that the read and write unit ( 86 ) is further designed to match the identification and position data with production parameter.

4. The scraping device according to claim 3 , characterized in that the read and write unit ( 86 ) is configured to output a warning message and a control signal when the comparison of the production parameters with the identification and position data outside a predetermined deviation.

5. The scraping device according to claim 4 , characterized in that the warning message comprises a visual and/or acoustic signal.

6. The scraping device according to claim 4 , characterized in that the control signal is configured to automatically influence operating process of the rotary press.
