Abstract

The blade (5) is used in combination with a lower blade and is held by a device assembled of a base (1), an adjusting mechanism (2), and the holding unit (4) exceeding from a transversally positioned element (3). An infrared sensor (6) is integrated in the element (3) in order to measure the temperature created when the unit is operated. The sensor element (6) or several of them belonging to several blade units can be connected to a display device.

Description

Die Erfindung betrifft Kreismesserhalter in Längsschneidemaschinen mit einem in einem Messerkopf gelagertem Kreismesser. Derartige gattungsgemäße Kreismesserhalter sind in vielfachen Bauformen bekannt, wie z.B. Messerhalter für den Scherenschnitt in der Ausführung gemäss EP 0 925 159 oder für den Quetschschnitt in der Ausführung gemäss DE 20 2004 001 889 beschrieben.The invention relates to circular knife holder in longitudinal cutting machines with a knife blade mounted in a circular blade. Such generic circular knife holder are known in multiple designs, such as knife holder for the paper cutting in the embodiment according to EP 0 925 159 or for the squish in the execution according to DE 20 2004 001 889 described.

Es besteht hierbei das generelle Problem, den Verschleiss der Messerschneiden zu überwachen, um das Messer rechtzeitig auszuwechseln, bevor eine unzulässige Schnittqualität zu Materialausschuß führt.It Here is the general problem, the wear of the knife edges to monitor to replace the knife in time, before an impermissible cut quality leads to material rejection.

In der DE-GM 299 15 564 ist hierzu eine präventive Überwachungseinrichtung beschrieben, wobei im wesentlichen durch Messung der Umdrehungszahl die Laufzeit der Messer erfasst und überwacht wird. Über einen Rechner sind dabei die Standzeiten je nach zu schneidendem Material erfasst.In DE-GM 299 15 564 a preventive monitoring device is described for this purpose, essentially by measuring the number of revolutions of the runtime the knife is detected and monitored becomes. about A computer is the service life depending on the cutting Material recorded.

Diese Einrichtung weist den Nachteil auf, daß bedienerseitige individuelle Einstellungen des Kreismessers, wie z.B. Eintauchtiefe und Einstelldruck im Scherenschnittsystem nicht erfasst werden, die jedoch einen wesentlichen Einfluss auf den Verschleiss der Messerschneide haben.These Device has the disadvantage that the user-side individual Settings of the circular knife, such as Immersion depth and set pressure in the paper cutting system, but which are essential Influence on the wear of the knife edge have.

Der Erfindung liegt die Aufgabe zu Grunde, diesen Nachteil zu beheben.Of the Invention is based on the object to remedy this disadvantage.

Die Lösung dieser Aufgabe geht von dem Grundgedanken aus, eine direkte Verschleisserkennung im Vorhinein durch berührungslose Temperaturmessung der Messerschneide zu erhalten, da durch den Verschleiß die erhöhte Reibung einen Temperaturanstieg bewirkt. Hierzu wird der Messerhalter mit einem Infrarotmeßkopf versehen, der mit einer separaten Elektronik verbunden ist.The solution This task is based on the basic idea of direct wear detection in advance by non-contact To get temperature measurement of the knife edge, as due to the wear, the increased friction causes a temperature increase. For this purpose, the knife holder with an infrared measuring head provided, which is connected to a separate electronics.

In der Zeichnung sind zwei Ausführungsbeispiele näher erläutert. Es zeigt:In the drawing are two embodiments explained in more detail. It shows:

1 einen Kreismesserhalter für den Scherenschnitt mit Temperaturmesseinrichtung, 1 a circular knife holder for paper cutting with temperature measuring device,

2 einen Kreismesserhalter für den Quetschschnitt mit Temperaturmesseinrichtung. 2 a circular knife holder for the squish with temperature measuring device.

In 1 ist ein Kreismesserhalter für den Scherenschnitt gemäß EP 0 925 159 in der Seitenansicht dargestellt. Dieser besteht im wesentlichen aus einem Grundkörper 1, einem Stellantrieb 2 und daran über eine Traverse 3 befestigtem Messerkopf 4 mit darin gelagertem Kreismesser 5 als Obermesser, welches mit einem hier nicht dargestellten Untermesser zusammenarbeitet. An der Traverse 3 ist ein Infrarotmeßkopf 6 befestigt, dessen Temperatursensor in geringem Abstand axial zur Messerschneide des Kreismessers steht. Über ein Verbindungskabel 7 ist der Meßkopf eines oder mehrerer Messerhalter permanent oder steckbar mit einer zentralen, progammierbaren Meßelektronik mit LCD-Display verbunden. Nach Einsatz eines neuen Kreismessers und Erreichen einer konstanten Betriebstemperatur wird lediglich eine erhöhte Fehler-Sollwert-Temperatur eingegeben, die über die Anzeige z.B. visuell überwacht werden kann oder bei Erreichen optisch oder akustisch angezeigt wird.In 1 is a circular knife holder for paper cutting according to EP 0 925 159 shown in the side view. This consists essentially of a basic body 1 , an actuator 2 and about a traverse 3 attached knife head 4 with circular knife stored therein 5 as an upper knife, which cooperates with a lower knife, not shown here. At the Traverse 3 is an infrared probe 6 attached, the temperature sensor is at a small distance axially to the knife edge of the circular blade. Via a connection cable 7 the measuring head of one or more knife holder is permanently or pluggable connected to a central, programmable measuring electronics with LCD display. After using a new circular blade and reaching a constant operating temperature only an increased error setpoint temperature is entered, which can be visually monitored via the display, for example, or visually or acoustically displayed when it reaches.

In 2 ist die Seitenansicht eines Kreismesserhalters für den Quetschschnitt gemäß DE 20 2004 001 889 dargestellt. Dieser besteht im wesentlichen aus einem Grundkörper 1 und darin geführten Führungsstangen 2.1/2, die einerseits mit einem Kolben im Zylinder 3 und andererseits mit einer Traverse 4 fest verbunden sind, welche den Messerkopf 5 mit darin gelagertem Quetschmesser 6 trägt. Am Grundkörper 1 ist ein Infrarotmeßkopf 7 befestigt, dessen Temperatursensor in geringem Abstand radial zur Messerschneide des Kreismessers steht. Über ein Verbindungskabel 8 ist der Meßkopf eines oder mehrerer Messerhalter permanent oder steckbar mit einer zentralen, progammierbaren Meßelektronik mit LCD-Display verbunden.In 2 is the side view of a circular knife holder for the squish according to DE 20 2004 001 889 shown. This consists essentially of a basic body 1 and guide rods guided therein 2.1 / 2, on the one hand with a piston in the cylinder 3 and on the other hand with a crossbar 4 are firmly connected, which the cutterhead 5 with a crushing knife stored therein 6 wearing. At the base body 1 is an infrared probe 7 attached, the temperature sensor is at a small distance radially to the knife edge of the circular blade. Via a connection cable 8th the measuring head of one or more knife holder is permanently or pluggable connected to a central, programmable measuring electronics with LCD display.
