Lösung solution
Ausgehend von den bekannten Verfahren wird nach der Erfindung vorgeschlagen, dass der Zustand zwischen Untermesser und Untermesserträger gemessen wird. Zwischen Untermesser und Untermesserträger sind die Messelemente einerseits sehr nah am Scherpunkt zwischen Untermesser und Scherzylinder - also an der zur Beurteilung des Betriebszustands wichtigsten und sensibelsten Stelle des Schneidzeugs, andererseits aber von allen beweglichen Teilen und von der Flächenware getrennt und vor Einflüssen im Betrieb der Schermaschine Starting from the known methods, it is proposed according to the invention that the condition between the lower blade and the lower blade carrier is measured. Between the lower blade and the lower blade carrier, the measuring elements are on the one hand very close to the point of shear between the lower blade and the shear cylinder - ie the most important and sensitive point of the cutting tool, but also separated from all moving parts and the fabric and from influences during operation of the shearing machine

Diese Schwingungen sind die Ursache der charakteristischen Geräusche, anhand derer im Stand der Technik das In a method according to the invention, the measurement preferably comprises a vibration measurement. The mechanical sliding of the shear coils on the Lower blade generates during the shear operation vibrations that continue in the components of the cutting tool. These vibrations are the cause of the characteristic noise, based on which in the prior art

Anhand der von den Drucksensoren 10, dem Beschleunigungssensor 1 1 und dem Temperatursensor 12 gemessenen Werte sowie anhand des Antriebsmoments und der Drehzahl des Scherzylinders 3 wird der Zustand des Schneidzeugs 1 im statischen und dynamischen Betrieb erfasst, in einer Maschinensteuerung gespeichert, von dieser über ein Mobilfunknetz an einen Server übermittelt und dort mittels eines Expertensystems interpretiert. Die Maschinensteuerung, das Mobilfunknetz und der Server sind nicht dargestellt. Based on the values measured by the pressure sensors 10, the acceleration sensor 11 and the temperature sensor 12, as well as the drive torque and the rotational speed of the shearing cylinder 3, the state of the cutting tool 1 is detected in static and dynamic operation, stored in a machine control system, via a mobile radio network transmitted to a server and interpreted there by means of an expert system. The machine control, the mobile network and the server are not shown.
Basierend auf der Interpretation der Zustandswerte ermittelt das Expertensystem Einstellparameter zur Optimierung der Schneidleistung und des generellen Zustande des Schneidzeugs 1 und übermittelt diese zurück an die Based on the interpretation of the state values, the expert system determines adjustment parameters for optimizing the cutting performance and the general state of the cutting tool 1 and transmits these back to the
Maschinensteuerung. Die Maschinensteuerung ändert anhand der Machine control. The machine control changes on the basis of
Einstellparameter automatisch die Drehzahl des Scherzylinders 3, die Setting parameters automatically the speed of the shear cylinder 3, the
