Abstract
The invention relates to a punch for a tableting machine. The punch preferably has a measuring device that can function in an energy self-sufficient manner independently of the power supply to the tableting machine. Furthermore, the invention relates to a tableting machine comprising the above-mentioned punch and a method for monitoring a tableting machine with the punch according to the invention during operation.
Claims18
A punch for a tableting machine comprising:
- a measuring device that is energy self-sufficient and can function independently of a power supply to the tableting machine, wherein the measuring device is incorporated inside a punch body and comprises a first sensor for recording a force and a second sensor for recording an acceleration of the punch,
- wherein the measuring device comprises a communication unit, a memory unit, an energy storage unit and a computing unit,
- wherein the computing unit comprises a processor unit adapted to process measured values obtained as raw data to obtain processed measured values,
- wherein the communication unit is configured for a wireless transmission of the processed measured values, to a control unit of the tableting machine,
- wherein the control unit is configured to receive the processed measured values, during and/or after compression procedures,
- wherein the control unit is further configured to perform an analysis of the processed measured values and to adjust operating parameters of the tableting machine, when the analysis of the processed measured values indicates a defective compression procedure,
- and wherein the analysis of the processed measured values takes place online (directly) during operation of the tableting machine without the punch having to be removed from the tableting machine.
