Abstract

Films are sealed between a sealing roll(6) and a heating roll(1), movement of the latter towards the former being produced through a linear guide(2). Pressure is exerted on the heating roll by a drive system(8,8.1,8.2) acting through the linear guide, the pressure being directed normal to the line contact between both rolls. A swiveling bearing between the heating roll(1) and the linear guide(2) compensates for small movements of the heating roll about an imaginary axis(7) between both rolls(1,6) and comprises a circular arc guide(4) and/or one or more bearing rollers(5). A central bearing roller(5) engages with one side of the guide and two further bearing rollers engage with the opposite side. Bearing rollers(5) are mounted in a housing onto which pressure is applied by a servomotor(8) which rotates a spindle(8.1) pressing a nut(8.2) onto a spring. The spring is connected to the linear guide and forms a cardan type joint relative to the nut.

Beschreibung des Ausführungsbeispielsdescription of the embodiment

Eine Heizwalze 1 wird über ein Linearführungssystem 2 geführt. An dem Linearführungssystem 2 ist eine gabelförmige Heizwalzenlagerung 3 über eine Kreisbogenführung 4 und den Lagerollen 5 winkelbeweglich um die in der Tangentialebene zwischen Heiz- und Siegelwalze 6 liegende fiktive Drehachse 7 gelagert. Die Krafteinleitung in das Linearführungssystem 2 erfolgt über einen numerisch gesteuerten Servomotor 8. Eine mit dem Servomotor 8 gekoppelte Planetenrollspindel bzw. Kugelrollspindel 8.1 steht in Eingriff mit einer Spindelmutter 8.2, die wiederum mit einem Membran-Federelement 9 gekoppelt ist.A heating roller 1 is via a linear guide system 2 guided. On the linear guide system 2 is a fork-shaped heat roller bearing 3 over a circular arc guide 4 and the storage rolls 5 angularly movable around the in the tangential plane between heating and sealing roller 6 lying fictional axis of rotation 7 stored. The introduction of force into the linear guide system 2 via a numerically controlled servomotor 8th , One with the servomotor 8th coupled planetary roller spindle or ball screw 8.1 is engaged with a spindle nut 8.2 , in turn, with a diaphragm spring element 9 is coupled.

Der Servomotor 8 bewegt die Heizwalze 1 über das Linearführungssystem 2 in derselben Richtung, in der auch die Heizwalze 1 in Normalenrichtung Kraft auf die in Linienberührung mit der Heizwalze 1 stehenden Siegelwalze 2 ausübt. Diese Krafteinleitung in Normalenrichtung erfolgt unmittelbar, das heißt ohne Verwendung aufwendiger Umlenk- bzw. Hebelmechanismen. Um dennoch Bewegungen um die effektive Drehachse 7 ausgleichen zu können, ist zwischen Linearführungssystem 2 und der gabelförmigen Heizwalzenlagerung 3 eine Schwenklagerung, bestehend aus Kreisbogenführung 4 mit Lagerollen 5, vorgesehen. Hierzu ist die Kreisbogenführung 4 starr mit der Heizwalzenlagerung 3 verbunden. Die Verbindung zwischen Heizwalzenlagerung 3 und Linearführungssystem 2 erfolgt nun durch die Lagerollen 5.The servomotor 8th moves the heating roller 1 over the linear guide system 2 in the same direction, in which also the heating roller 1 in the normal direction force on in line contact with the heating roller 1 standing seal roller 2 exercises. This application of force in the normal direction is immediate, that is without the use of complex deflection or lever mechanisms. Nevertheless, movements around the effective axis of rotation 7 to be able to compensate is between linear guide system 2 and the forked heat roller bearing 3 a pivot bearing, consisting of circular arc guide 4 with bearing rollers 5 , intended. For this purpose, the circular arc guide 4 rigid with the heat roller bearing 3 connected. The connection between heat roller bearing 3 and linear guide system 2 Now takes place through the bearing rollers 5 ,

Die Lagerollen 5 sind in einem nicht näher bezeichneten Gehäuse drehbar gelagert, welches fester Bestandteil des Linearführungssystems 2 ist. Die Lagerollen 5 sind im Eingriff mit der Kreisbogenführung 4, das heißt sie werden durch diese geführt. Dadurch wird eine geringe Schwenkbewegung der Heizwalzenlagerung 3 bzw. der Heizwalze 1 gegenüber dem Linearführungssystem 2 zugelassen. Vorzugsweise ist die Kreisbogenführung 4 so ausgestaltet, dass der Kreisbogen nach unten hin, das heißt in Richtung zur Heizwalze 1, gebogen ist. Vorzugsweise handelt es sich um insgesamt sechs Lagerollen 5, jeweils drei auf Vorder- und Hinterseite der Heizwalzenlagerung 3 ausgebildet. Auf der Rückseite der Heizwalzenlagerung 3 ist ebenfalls eine in der Figur nicht sichtbare Kreisbogenführung fest mit der Heizwalzenlagerung 3 verbinden. Pro Kreisbogenführung 4 ist nun eine mittig angeordnete Lagerlagerolle 5 vorgesehen, die in Eingriff mit dem unteren Teil der Führung der Kreisbogenführung 4 steht, das heißt mit der zur Heizwalze 1 hin orientierten Führung. Links und rechts von der gedachten Mittelachse sind pro Führung nun zwei weitere Lagerollen 5 angebracht, die im Eingriff mit dem nach oben hin, das heißt von der Heizwalze 1 weg orientierten Kreisbogenführung 4 stehen. Die beiden oberen Lagerollen 5 weisen vorzugsweise denselben Abstand zur Oberfläche der Heizwalze 1 auf. Die über die Kreisbogenführung 4 realisierte Schwenklagerung der Heizwalze 1 ermöglicht die Ausbildung einer vollkommen gleichmäßigen, geschlossenen Kontaktlinie zwischen Heizwalze 1 und Siegelwalze 6. Reibungseffekte durch axiale Relativbewegungen zwischen Heizwalze 1 und Siegelwalze 6 können sich hierbei aufgrund der Schwenkachsenlage unmittelbar an der Wirkstelle zwischen Heizwalze 1 und Siegelwalze 6 nicht auswirken.The bearing rollers 5 are rotatably mounted in a housing unspecified, which is an integral part of the linear guide system 2 is. The bearing rollers 5 are engaged with the circular arc guide 4 that is, they are guided by them. As a result, a small pivoting movement of the Heizwalzenlagerung 3 or the heating roller 1 opposite the linear guide system 2 authorized. Preferably, the circular arc guide 4 so outraged tet that the arc down, that is towards the heating roller 1 , is bent. Preferably, there are a total of six bearing rollers 5 , three each on the front and rear side of the heat roller bearing 3 educated. On the back of the heated roller bearing 3 is also not visible in the figure circular arc guide fixed to the Heizwalzenlagerung 3 connect. Per circular arc guide 4 is now a centrally located bearing roller 5 provided, which engage with the lower part of the guide of the circular arc guide 4 stands, that is with the heat roller 1 oriented leadership. Left and right of the imaginary center axis are now two more bearing roles per guide 5 attached, which engages with the upwards, that is from the heating roller 1 path oriented circular arc guide 4 stand. The two upper bearing rollers 5 preferably have the same distance to the surface of the heating roller 1 on. The over the circular arc guide 4 realized pivot bearing of the heating roller 1 allows the formation of a perfectly uniform, closed contact line between the heating roller 1 and sealing roller 6 , Friction effects due to axial relative movements between heat roller 1 and sealing roller 6 may be due to the pivot axis position directly at the point of action between the heating roller 1 and sealing roller 6 do not affect.

Die Krafteinleitung in das Linearführungssystem 2 lässt sich anhand 2 näher erläutern. Die Spindel 8.1 des Servomotors 8 (beispielsweise eine Planetenrollspindel bzw. alternativ eine Kugelrollspindel) wirkt über die Spindelmutter 8.2 auf das Membran-Federelement 9 ein. Das Membran-Federelement 9 ist fest mit dem Gehäuse verbunden, das der Lagerung der Lagerollen 5 dient. Zudem besteht das Linearführungssystem 2 aus beispielhaft zwei Führungen, um eine Linearbewegung des Gehäuses vom Aufbringen einer Kraft in Normalenrichtung auf die Heizwalze 1 zu ermöglichen. Das Membran-Federelement 9 wandelt einerseits die Wegamplitude der Spindelmutter 8.2 in die erforderliche Anpresskraft zwischen Heizwalze 1 und Siegelwalze 6 um. Auf der anderen Seite dient das Membran-Federelement 9 zur Drehmomentenabstützung bzw. zur kardanischen Lagerung der Spindelmutter 8.2.The introduction of force into the linear guide system 2 can be based on 2 explain in more detail. The spindle 8.1 of the servomotor 8th (For example, a planetary roller spindle or alternatively a ball screw) acts on the spindle nut 8.2 on the diaphragm spring element 9 one. The membrane spring element 9 is firmly connected to the housing, which is the storage of the bearing rollers 5 serves. In addition, there is the linear guide system 2 by way of example two guides to a linear movement of the housing by applying a force in the normal direction to the heating roller 1 to enable. The membrane spring element 9 on the one hand converts the path amplitude of the spindle nut 8.2 in the required contact force between heat roller 1 and sealing roller 6 around. On the other side is the diaphragm spring element 9 for torque support or for cardanic mounting of the spindle nut 8.2 ,

Zur Konstanthaltung des Siegeldrucks muss, abhängig von der Oberflächenstruktur bzw. der Winkellage der Siegelwalze 6 die entsprechende Kraftamplitude generiert werden. Hierzu wird dem Membran-Federelement 9 unter Berücksichtigung der Federkennlinie ein entsprechender Federweg aufgeprägt. Vorzugsweise wird hierzu ein Druckregelkreis bzw. Drucksteuerkreis implementiert wie beispielsweise in der DE 100 52 218 A14 gezeigt. Hierzu sind nicht dargestellte Druckerfassungssensoren anzuordnen, dessen Ausgangssignal einer Druckregelung bzw. Drucksteuerung zuzuführen ist. Die Druckregelung bzw. -steuerung steuert den Servomotor 8 im Sinne eines gewünschten Drucks an.To keep the sealing pressure constant, depending on the surface structure or the angular position of the sealing roller 6 the corresponding force amplitude can be generated. For this purpose, the membrane spring element 9 imprinted a corresponding spring travel taking into account the spring characteristic. Preferably, for this purpose, a pressure control loop or pressure control circuit is implemented, for example in the US Pat DE 100 52 218 A14 shown. For this purpose, pressure detection sensors not shown are to be arranged, whose output signal is to be supplied to a pressure control or pressure control. The pressure control controls the servomotor 8th in the sense of a desired pressure.
