Die Erfindung betrifft zunächst ein Verfahren zum Betrieb eines Schneidzeugs mit einem um eine Längsachse rotierenden Scherzylinder und auf dem Scherzylinder angebrachten Scherspiralen, mit einem Untermesserträger, der ein parallel zu der Längsachse verlaufendes Untermesser trägt, wobei ein Zustand des Schneidzeugs gemessen wird, und wobei an jeder Scherspirale ein Scherpunkt, in dem ein zwischen Scherspirale und Untermesser geführtes Schnittgut tangential zu dem Scherzylinder abgeschert wird, kontinuierlich von einem Einlaufende zu einem Auslaufende des Untermessers wandert. Weiterhin betrifft die Erfindung ein Schneidzeug gemäss Oberbegriff von Anspruch 13.The invention relates first to a method for operating a cutting tool with a shear cylinder rotating about a longitudinal axis and with shear spirals mounted on the shear cylinder, with a lower blade carrier which carries a lower blade extending parallel to the longitudinal axis, a condition of the cutting tool being measured, and with each Shear spiral a shear point at which a cut material guided between the shear spiral and the lower blade is sheared tangentially to the shear cylinder and migrates continuously from an inlet end to an outlet end of the lower blade. The invention also relates to a cutting tool according to the preamble of
Solche Verfahren und Schneidzeuge werden zum Scheren der Oberfläche von Flächenware wie Textilien, Teppichen, Fellen und Pelzen verwendet, um insbesondere eine gleichmäßige Florhöhe bzw. Faserlänge zu erzeugen. Das Schneidzeug mit den auf den Scherzylinder aufgezogenen helixförmigen Scherspiralen wird als Einheit in eine Schermaschine eingebaut. Im Betrieb der Schermaschine rotiert der Scherzylinder mit den Scherspiralen tangential gegen das Untermesser. Die Scherspiralen laufen über die Schneidkante des Untermessers und bilden entlang der Schneidbahn an der Unterkante einen fortlaufenden Scherenschnitt. Die Flächenware wird über einen Schertisch der Schermaschine derart an die Schneidkante herangeführt, dass über die gewünschte Florhöhe überstehende Faseranteile zwischen Scherspirale und Untermesser geführt und abgetrennt werden.Such methods and cutting tools are used to shear the surface of flat goods such as textiles, carpets, hides and furs in order to produce, in particular, a uniform pile height or fiber length. The cutting tool with the helical shear spirals drawn onto the shear cylinder is installed as a unit in a shearing machine. When the shearing machine is in operation, the shear cylinder with the shear spirals rotates tangentially against the lower blade. The shear spirals run over the cutting edge of the lower knife and form a continuous scissor cut along the cutting path at the lower edge. The flat goods are brought up to the cutting edge via a shear table of the shearing machine in such a way that fiber portions protruding over the desired pile height are guided between the shear spiral and the lower blade and cut off.
Der Betriebszustand des Schneidzeugs wird in den bekannten Verfahren im Wesentlichen durch das Bedienpersonal anhand von Schnittproben, der durch das Zusammenwirken von Scherzylinder und Untermesser entstandenen Laufbahn und von anhand von charakteristischen Laufgeräuschen der Schermaschine beurteilt. Korrekturen nimmt das Bedienpersonal zumeist manuell vor, insbesondere wird die Position des Untermessers zum Scherzylinder durch Spannbügel, Stellschrauben oder andere mechanische Verstelleinrichtungen eingestellt.In the known methods, the operating state of the cutting tool is essentially assessed by the operating personnel on the basis of cutting samples, the career created by the interaction of the shear cylinder and lower blade, and on the basis of characteristic running noises of the shearing machine. The operating personnel usually make corrections manually; in particular, the position of the lower blade in relation to the shear cylinder is set by means of clamping brackets, adjusting screws or other mechanical adjustment devices.
Im Hintergrund der Erfindung schlägt
Wissenschaftliche Untersuchungen betreffen die Temperatur des Untermessers und die Schallemissionen der Schneidmaschine.Scientific investigations concern the temperature of the lower blade and the noise emissions of the cutting machine.
Der Erfindung liegt die Aufgabe zugrunde, den Betriebszustand des Schneidzeugs zu messen.The invention is based on the object of measuring the operating state of the cutting tool.
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 geschützt.Based on the known method, it is proposed according to the invention that the state between the lower blade and the lower blade carrier is measured. Between the lower knife and the lower knife carrier, the measuring elements are on the one hand very close to the shear point between the lower knife and the shear cylinder - i.e. at the most important and sensitive point of the cutting tool for assessing the operating condition, but on the other hand they are separated from all moving parts and from the flat goods and protected from influences during the operation of the shearing machine .
Vorzugsweise umfasst in einem erfindungsgemäßen Verfahren die Messung eine Schwingungsmessung. Das mechanische Abgleiten der Scherspiralen auf dem Untermesser erzeugt während des Scherbetriebes Schwingungen die sich in den Bauteilen des Schneidzeuges fortsetzen. Diese Schwingungen sind die Ursache der charakteristischen Geräusche, anhand derer im Stand der Technik das Bedienpersonal den Betriebszustand beurteilt.In a method according to the invention, the measurement preferably comprises a vibration measurement. The mechanical sliding of the shear spirals on the The lower blade generates vibrations during the shearing operation, which continue in the components of the cutting tool. These vibrations are the cause of the characteristic noises on the basis of which the operating personnel assess the operating status in the prior art.
Anhand der Schwingungsmuster lässt sich die Wuchtgüte des Scherzylinders, die Anzahl der Spiralen und deren Hiebausprägung auf dem Scherzylinder bestimmen. Zudem können anhand charakteristischer Schwingungsbilder betriebskritische Zustände wie gelockerte Scherspiralen frühzeitig erkannt werden, bevor weitere Schäden am Schneidzeug entstehen.The balance quality of the shear cylinder, the number of spirals and their impact on the shear cylinder can be determined on the basis of the vibration pattern. In addition, operating-critical conditions such as loosened shear spirals can be recognized at an early stage on the basis of characteristic vibration patterns, before further damage occurs to the cutting tool.
Weiter vorzugsweise wird in einem solchen erfindungsgemäßen Verfahren die Schwingung an dem Einlaufende gemessen. Als Einlaufende wird das Ende des Untermessers in Längsrichtung des Scherzylinders bezeichnet, an dem die Scherspiralen im Betrieb erstmalig mit dem Untermesser zusammenwirken. Durch Kontakte zum Untermesser sind an dieser Stelle die Scherspiralen besonders bruchgefährdet.In such a method according to the invention, the vibration at the inlet end is also preferably measured. The end of the lower blade in the longitudinal direction of the shear cylinder, at which the shear spirals interact with the lower blade for the first time during operation, is referred to as the inlet end. The shear spirals are particularly vulnerable to breakage at this point due to contact with the lower blade.
Vorzugsweise umfasst in einem erfindungsgemäßen Verfahren die Messung eine Temperaturmessung. Das Untermesser wird im Betrieb der Schermaschine durch die Reibung im Scherpunkt zwischen Untermesser und den Scherspiralen. erwärmt. Hier können Temperaturen weit über 100 °C entstehen, die zur Beeinträchtigung der Flächenware und zur Zerstörung des Untermessers führen. Die Temperatur ist also ein wesentliches Merkmal eines optimal wirkenden Schneidzeuges. Zu hohe Temperaturen am Untermesser können insbesondere entstehen durch zu hohe Anpresskräfte zwischen Untermesser und Scherspirale, eine zu breite Laufbahn der Scherspiralen auf dem Untermesser, mangelnde oder fehlende Schmierung der Berührungslinie auf dem Untermesser und durch zu hohe Schnittgeschwindigkeiten am Scherzylinder.In a method according to the invention, the measurement preferably comprises a temperature measurement. The lower blade is in operation of the shearing machine by the friction in the shear point between the lower blade and the shear spirals. warmed up. Temperatures well above 100 ° C can arise here, which can impair the fabric and destroy the bottom blade. The temperature is therefore an essential characteristic of a cutting tool that works optimally. Temperatures that are too high on the lower blade can result from excessive contact pressure between the lower blade and the shear spiral, too wide a track of the shear spirals on the lower blade, insufficient or missing lubrication of the contact line on the lower blade and excessive cutting speeds on the shear cylinder.
Weiter vorzugsweise wird in einem solchen erfindungsgemäßen Verfahren die Temperatur an dem Auslaufende gemessen. An dieser Stelle wirkt sich mangelnde Schmierung zuerst aus.In such a method according to the invention, the temperature at the outlet end is also preferably measured. This is where insufficient lubrication takes effect first.
Vorzugsweise umfasst in einem erfindungsgemäßen Verfahren die Messung eine Kraftmessung. Über die Druckkraft zwischen Untermesser und Untermesserträger werden statische Fehleinstellungen in der Lage des Scherzylinders zum Untermesser und Abweichungen der Längsachse des Scherzylinders horizontal oder vertikal von der parallelen Lage zur Schneidbahn identifiziert. Die Messung der Druckkräfte vereinfacht Einstellarbeiten bei Erstinbetriebnahme, Wartung, Instandhaltung und Wiederinbetriebnahme nach Reparaturen und Maschinenstillstandzeiten.In a method according to the invention, the measurement preferably comprises a force measurement. Static incorrect settings in the position of the shear cylinder in relation to the lower blade and deviations in the longitudinal axis of the shear cylinder horizontally or vertically from the position parallel to the cutting path are identified via the pressure force between the lower knife and the lower knife carrier. The measurement of the pressure forces simplifies setting work for initial commissioning, maintenance, servicing and recommissioning after repairs and machine downtimes.
Die dynamische Messung der Druckkräfte ermöglicht eine Beurteilung des Zustands des Schneidzeugs im laufenden Betrieb. In Kombination mit den gemessenen Werten aus Temperaturveränderung, Körperschall und Drehmoment lassen sich präzise Daten zum Schneidverhalten bis hin zum Servicebedarf ermitteln.The dynamic measurement of the pressure forces enables the condition of the cutting tool to be assessed during operation. In combination with the measured values from temperature change, structure-borne noise and torque, precise data on cutting behavior and service requirements can be determined.
Weiter vorzugsweise wird in einem solchen erfindungsgemäßen Verfahren die Kraft am Einlaufende, am Auslaufende sowie zwischen Einlaufende und Auslaufende gemessen. Die Kombination dieser drei Messwerte ermöglicht Aussagen zur Parallelität von Scherzylinder und Untermesser sowie zur Krümmung der Schneidbahn. Durch Messungen der Kraft an weiteren Stellen kann der Zustand des Schneidzeugs genauer beschrieben werden.In such a method according to the invention, the force is also preferably measured at the inlet end, at the outlet end and between the inlet end and the outlet end. The combination of these three measured values enables statements to be made about the parallelism of the shear cylinder and lower knife as well as the curvature of the cutting path. The condition of the cutting tool can be described more precisely by measuring the force at other points.
Vorzugsweise wird in einem erfindungsgemäßen Verfahren der gemessene Zustand an eine Auswerteeinrichtung übermittelt. Die Übermittlung in eine gemeinsame Auswerteeinrichtung ermöglicht die Korrelation verschiedener Messwerte, die Speicherung von Messwerten und damit die Analyse von zeitlichen Entwicklungen sowie die Erstellung von Prognosen.In a method according to the invention, the measured state is preferably transmitted to an evaluation device. The transmission to a common evaluation device enables the correlation of different measured values, the storage of measured values and thus the analysis of developments over time as well as the creation of forecasts.
Weiter vorzugsweise wird in einem solchen erfindungsgemäßen Verfahren der Zustand analog oder digital drahtlos übermittelt. Die drahtlose Übermittlung insbesondere über ein Mobilfunknetz an einen zentralen Server erlaubt die Nutzung einer in Industriestaaten flächendeckend vorhandenen Infrastruktur.In such a method according to the invention, the state is further preferably transmitted in an analog or digital manner in a wireless manner. The wireless transmission, in particular via a cellular network to a central server, allows the use of an infrastructure that is available across the board in industrialized countries.
Vorzugsweise wertet weiterhin in einem solchen erfindungsgemäßen Verfahren die Auswerteeinrichtung den Zustand aus und erstellt eine Anweisung zum Ändern einer geometrischen Position des Scherzylinders und/oder des Untermessers. Die vorliegenden Messdaten und die daraus gewonnenen Handlungsanweisungen für das Bedienpersonal können zur Ausgabe am Bildschirm einer Maschinensteuerung aufbereitet werden. Anhand der Messdaten können statische und dynamische Betriebszustände beschrieben und visualisiert werden.Preferably, in such a method according to the invention, the evaluation device further evaluates the state and creates an instruction for changing a geometric position of the shear cylinder and / or the lower cutter. The existing measurement data and the instructions for the operating personnel obtained from them can be prepared for output on the screen of a machine control system. Static and dynamic operating states can be described and visualized on the basis of the measurement data.
Weiter vorzugsweise wird in einem solchen erfindungsgemäßen Verfahren die Position automatisch geändert. Die Maschinensteuerung kann mit diesen Messdaten auf definierte Sollzustände regeln und den Betrieb der Maschine in festgelegten Grenzen halten.The position is further preferably changed automatically in such a method according to the invention. With this measurement data, the machine control can regulate to defined target states and keep the operation of the machine within defined limits.
Vorzugsweise wird in einem erfindungsgemäßen Verfahren ein Antriebsmoment zum Rotieren des Scherzylinders gemessen und in die Auswertung einbezogen. Der Scherzylinder wird in üblichen Schermaschinen durch einen Elektromotor angetrieben. Die Antriebsleistung wird durch einen Umrichter gesteuert bzw. geregelt, der häufig Abweichungen oder Schwankungen im Leistungsbedarf erfasst, dokumentiert und zur weiteren Verarbeitung bereitstellt. Diese Daten lassen sich über Hard- und Softwareschnittstellen schnell und einfach auslesen und erlauben - insbesondere in Kombination mit den zuvor beschriebenen Messungen von Schwingungszuständen, Temperatur und Druckkraft zwischen Untermesser und Untermesserträger - umfangreiche Rückschlüsse auf den Betriebszustand.In a method according to the invention, a drive torque for rotating the shear cylinder is preferably measured and included in the evaluation. In conventional clippers, the shear cylinder is driven by an electric motor. The drive power is controlled or regulated by a converter, which frequently records deviations or fluctuations in the power requirement, documents them and makes them available for further processing. These data can be read out quickly and easily via hardware and software interfaces and allow - especially in combination with the measurements of vibration states, temperature and compressive force between the lower blade and the lower blade carrier described above - extensive conclusions to be drawn about the operating status.
