Abstract

The frame (1) contains a glue-applicator roller (5) rotarily driven on a center lengthwise axle (8), and a pressure roller (10) rotarily driven on a center lengthwise axle (11). A corrugated cardboard web (47) consisting of at least one covering web (50) and corrugated web (49) travels through the gap (53) between the glue-applicator and pressure rollers. A dynamometer (34) measures the actual force in the gap at right angles to the web. The height of the gap can be altered by an adjustment (36), and a regulator (43) compares the actual and nominal forces in the gap.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den Merkmalen des Anspruches 1 und durch eine Beleimungs-Vorrichtung mit den Merkmalen des Anspruches 4 gelöst. Die für eine optimale Beleimung der Spitzen der Well-Bahn erforderliche Ist-Kraft im Walzenspalt wird empirisch ermittelt.This object is achieved according to the invention by a method with the features of claim 1 and by a gluing device with the Features of claim 4 solved.

Diese Kräfte wirken nach unten. Ihnen entgegengerichtet wirken Kräfte, die einerseits im Walzenspalt 53 und andererseits an den Andrückkraft-Einstell-Einrichtungen 32, 33 entgegengerichtet nach oben angreifen. Die Summe dieser Kräfte ist also ebenfalls konstant. Die im Walzenspalt 53 auf die Wellpappe-Bahn 47 ausgeübte Ist-Kraft hängt also von den in den Andrückkraft-Einstell-Einrichtungen 32, 33 auftretenden Kräften ab. Wenn die im Walzenspalt 53 auf die Wellpappe-Bahn 47 ausgeübte Andrückkraft vergrößert werden soll, dann müssen entsprechend die in den Einrichtungen 32, 33 angreifenden Kräfte verringert werden und umgekehrt.For this purpose, the pressure drives 19 and 20 from the pressure fluid source 29 applied with a constant pressure so that it with a act constant force on the respective lever 13 or 14. This Forces and resulting from the weight of the levers 13, 14, the pressure roller 10 and the resulting forces on the levers 13, 14 are overall constant. These forces work downwards.

The the actual force exerted on the corrugated cardboard web 47 hangs in the nip 53 that is, from those occurring in the pressing force setting devices 32, 33 Forces. When the in the nip 53 on the corrugated web 47th exerted pressing force is to be increased, then must accordingly the forces acting in the devices 32, 33 are reduced and vice versa.

Von jeder Kraft-Meß-Einrichtung 34 wird die in dieser erfaßte, in der Einrichtung 32 bzw. 33 wirkende Ist-Kraft ständig über die Signal-Leitung 42 an die Regel-Einrichtung 43 gegeben und deren Summe dort mit einer vorher eingestellten Soll-Kraft verglichen. Die Einstellung dieser Soll-Kraft kann auch der Kraft entsprechen, die im Walzenspalt 53 auf die Wellpappe-Bahn 47 wirken soll. Da aus den genannten Gründen die Summe dieser Kräfte und der in den Einrichtungen 32, 33 wirkenden Kräfte konstant ist, kann in der Regel-Einrichtung 43 eine entsprechende Umrechnung erfolgen. Wenn die Summe der in jeder Kraft-Meß-Einrichtung 34 gemessenen Ist-Kräfte größer wird als die vorher eingestellte Soll-Kraft, dann heißt dies, daß die im Walzenspalt 53 wirkende Ist-Kraft zu klein geworden ist, daß also dessen Höhe a zu groß geworden ist. In diesem Fall wird aufjeden Verstell-Antrieb 40 ein Steuersignal zur Verschiebung des zugeordneten Keils 37 in der Richtung gegeben, daß die Höhe a des Walzenspaltes 53 reduziert wird, und zwar so lange, bis die in den Einrichtungen 32, 33 gemessenen Ist-Kräfte, und damit mittelbar auch die im Walzenspalt 53 wirkende Kraft, wieder dem vorher eingestellten Soll-Wert entsprechen.Each force measuring device 34 detects the force measuring device 34 in the device 32 or 33 actual force acting continuously via the signal line 42 given to the control device 43 and the sum there with a previously set target force compared. The setting of this target force can also correspond to the force exerted in the nip 53 on the corrugated web 47 should act. Because for the reasons mentioned the sum of these Forces and the forces acting in the devices 32, 33 is constant, a corresponding conversion can be carried out in the control device 43. When the sum of those measured in each force measuring device 34 Actual forces is greater than the previously set target force, then is called this is because the actual force acting in the nip 53 has become too small, that its height a has become too great. In this case everyone will Adjustment drive 40 a control signal for shifting the associated Given wedge 37 in the direction that the height a of the nip 53rd is reduced, namely until the measured in the devices 32, 33 Actual forces, and thus indirectly also those acting in the nip 53 Force, again correspond to the previously set target value.

Wenn dagegen die Summe der in jeder Kraft-Meß-Einrichtung 34 gemessenen Ist-Kräfte kleiner wird als die vorher eingestellte Soll-Kraft, dann heißt dies, daß die im Walzenspalt 53 wirkende Ist-Kraft zu groß geworden ist, daß also dessen Höhe a zu klein geworden ist. In diesem Fall wird auf jeden Verstell-Antrieb 40 ein Steuersignal zur Verschiebung des zugeordneten Keils 37 in der Richtung gegeben, daß die Höhe a des Walzenspaltes 53 vergrößert wird, und zwar so lange, bis die in den Einrichtungen 32, 33 gemessenen Ist-Kräfte und damit mittelbar auch die im Walzenspalt 53 wirkende Kraft, wieder dem vorher eingestellten Soll-Wert entsprechen.If, on the other hand, the sum of those measured in each force measuring device 34 Actual forces becomes smaller than the previously set target force, then this means that the actual force acting in the nip 53 has become too great is that its height a has become too small. In this case, is on each adjustment drive 40 has a control signal for shifting the associated one Given wedge 37 in the direction that the height a of the nip 53 is increased, and that until the devices 32, 33 measured actual forces and thus indirectly also those in the nip 53 acting force, again correspond to the previously set target value.

Die Regel-Einrichtung 43 und die Steuer-Einrichtung 45 können in der Weise miteinander verknüpft sein, daß für die Steuer-Einrichtung 45 bei Beginn eines Beleimungs-Vorganges eine Basis-Höhe a für die Wellpappe-Bahn 47 eingegeben wird, so daß der Einregelvorgang nicht zu lange dauert.The control device 43 and the control device 45 can in the Be linked together in such a way that for the control device 45 Start of a gluing process a base height a for the corrugated cardboard web 47 is entered so that the adjustment process does not take too long.

Im übrigen wird mittels des Andrück-Antriebes 19 auch die Andrück-Walze 10 nach oben abgehoben.Otherwise, the pressure roller 19 is also the pressure roller 10 lifted up.

Die in der Beleimungs-Vorrichtung beleimte Wellpappe-Bahn 47 wird in üblicher Weise einer bekannten Kaschier-Vorrichtung zugeführt, in der gegen die beleimten Spitzen 54 der Well-Bahn 49 eine weitere Deck-Bahn angelegt wird.The corrugated cardboard web 47 glued in the gluing device is shown in FIG Usually supplied to a known laminating device in which against the glued tips 54 of the corrugated sheet 49 another cover sheet is created.

Anstelle der zuvor beschriebenen Ausgestaltung kann die Regelung der Kraft im Walzenspalt 53 und damit die Steuerung der Höhe a des Walzenspaltes 53 über seine gesamte Länge auch in der Weise erfolgen, daß die von den beiden Kraft-Meß-Einrichtungen 34 der Andrückkraft-Einstell-Einrichtungen 32, 33 gemessenen Kräfte nicht aufsummiert und dann in der beschriebenen Weise weiterbehandelt werden, sondern daß sie einzeln mit dem jeweils halben Wert der Soll-Kraft im Walzenspalt 53 verglichen werden und daß dann eine entsprechende einzelne Ansteuerung der Abstands-Einstell-Vorrichtungen 36 der Andrückkraft-Einstell-Einrichtungen 32 bzw. 33 erfolgt. Auf diese Weise kann eine nicht-parallele Einstellung der Walzen 5 und 10 zueinander erfolgen, d.h. der Walzenspalt 53 hat gegebenenfalls nicht über die volle Länge die gleiche Höhe a; hiermit können aber unterschiedliche Dicken der Wellpappe-Bahn 47 über ihre Breite kompensiert werden, so daß auch über die Breite der Wellpappe-Bahn 47 keine zu geringen Andrückkräfte oder zu hohen Andrückkräfte auftreten können.Instead of the embodiment described above, the regulation of the Force in the nip 53 and thus the control of the height a of the nip 53 take place over its entire length in such a way that the of the two force measuring devices 34 of the pressing force setting devices 32, 33 measured forces are not added up and then in the described further treatment, but that they are individually with half the value of the target force in the nip 53 are compared and that then a corresponding individual control of the distance adjusting devices 36 of the pressing force adjusting devices 32 or 33. In this way, a non-parallel adjustment of the Rolls 5 and 10 occur towards each other, i.e. the nip 53 may have not the same height over the full length; hereby can different thicknesses of the corrugated cardboard web 47 compensated for their width be, so that even over the width of the corrugated web 47 no low pressing forces or excessive pressing forces can occur.
