Leimauftrags-Vorrichtung fur einseitig kaschierte WellpappeGlue application device for single-sided laminated corrugated cardboard

Die Erfindung betrifft eine Leimauftrags-Vorrichtung nach dem Oberbegriff des Anspruches 1.
5The invention relates to a glue application device according to the preamble of claim 1.
5

Bei derartigen bekannten Leimauftrags-Vorrichtungen erfolgt das Andrükken der Wellpappe-Bahn gegen die Leim-Aufiragswalze mittels Andrückwalzen oder Andrückschuhen. Dies birgt die Gefahr in sich, daß bei nicht exaktem Rundlauf der Andrückwalze die Wellpappe-Bahn unterschiedlich stark gegen die Auftragswalze angedrückt wird und damit eine unterschiedliche Beleimung der Spitzen der gewellten Papierbahn erfolgt. Es ist außerordentlich schwierig, den Spalt zwischen der Andrückwalze und der Leim-Auftragswalze über die volle Walzenbreite exakt einzustellen. Die Höhenverstellung der Andrückwalze bei Änderung der Papierqualität oder bei Änderung der Flute ist aufwendig. Die Gefahr einer Quetschung der einzelnen Wellen der gewellten Papierbahn ist verhältnismäßig groß, da nur eine Linienanlage der gewellten Papierbahn an der Auftragswalze gegeben ist. Weiterhin ist eine Geräuschentwicklung nicht zu unterbinden.In such known glue application devices, the corrugated cardboard web is pressed against the glue application roller by means of pressure rollers or pressure shoes. This entails the risk that if the pressure roller does not run exactly true, the corrugated cardboard web is pressed against the application roller with varying degrees of force, resulting in different gluing of the tips of the corrugated paper web. It is extremely difficult to set the gap between the pressure roller and the glue application roller exactly across the entire width of the roller. Adjusting the height of the pressure roller when the paper quality or the flute changes is complex. The risk of crushing the individual waves of the corrugated paper web is relatively high, since the corrugated paper web only contacts the application roller in a linear manner. Furthermore, noise cannot be prevented.

Auch das Andrücken der Wellpappe-Bahn mittels sogenannter Andrückschuhe birgt eine Reihe von Problemen in sich, beispielsweise verhältnismäßig starken Verschleiß, Vibrationen und unterschiedliche Anpreßkräfte.Pressing the corrugated cardboard web using so-called pressure shoes also entails a number of problems, such as relatively high wear, vibrations and different contact forces.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Leimauftrags-Vorrichtung zu schaffen, mittels derer auf einfache Weise eine gleichmäßige, weitgehend verschleißfreie Andrückung einer Wellpappe-Bahn an die Leim-Auftragswalze möglich ist.The invention is therefore based on the object of creating a glue application device by means of which a uniform, largely wear-free pressing of a corrugated cardboard web onto the glue application roller is possible in a simple manner.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale im Kennzeichnungsteil des Anspruches 1 gelöst. Über die erfindungsgemäßen Maßnahmen ist eine gleichmäßige Anpressung über die volle Arbeitsbreite, d. h. über die volle Breite der Wellpappe-Bahn möglich. Es kann eine definierte Umschlingung zwischen Wellpappe-Bahn und Leim-Auftragswalze erreicht werden, so daß insbesondere die Flächenpressung niedrig ist. Dadurch, daß die Wellpappe-Bahn großflächig am Untertrum des Bandes anliegt, treten keine Vibrationen auf, so daß auch die Geräuschentwicklung minimiert wird.
10This object is achieved according to the invention by the features in the characterizing part of claim 1. The measures according to the invention enable uniform pressure to be applied over the full working width, ie over the full width of the corrugated cardboard web. A defined wrap between the corrugated cardboard web and the glue application roller can be achieved, so that the surface pressure in particular is low. Because the corrugated cardboard web lies against the lower run of the belt over a large area, no vibrations occur, so that noise is also minimized.

Die Unteransprüche geben vorteilhafte Ausgestaltungen wieder.The subclaims reflect advantageous embodiments.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung, die eine Leimauftrags-Vorrichtung in schematischer Darstellung in Seitenansicht zeigt.Further features, advantages and details of the invention emerge from the following description of an embodiment with reference to the drawing, which shows a glue application device in a schematic representation in side view.

Die in der Zeichnung dargestellte Leimauftrags-Vorrichtung weist einen Leim-Behälter 1 und eine in diesen eintauchende Leim-Auftragswalze 2 auf, an der eine Abquetschwalze 3 anliegt, die einen Spalt zur Leim-Auftragswalze 2 begrenzt, so daß durch die Einstellung der Abquetschwalze 3 die Dicke der Schicht an Leim 4 auf der Auftragswalze 2 bestimmt wird. An der Abquetschwalze 3 und der Auftragswalze 2 liegen Rakeln 5, an. Der mittels den Rakeln 5, 6 abgestreifte Leim 4 tropft in den Leim-Behälter 1.The glue application device shown in the drawing has a glue container 1 and a glue application roller 2 which is immersed in the latter and against which a squeegee roller 3 is located, which defines a gap to the glue application roller 2, so that the thickness of the layer of glue 4 on the application roller 2 is determined by the setting of the squeegee roller 3. Squeegees 5, 6 are located on the squeegee roller 3 and the application roller 2. The glue 4 scraped off by the squeegees 5, 6 drips into the glue container 1.

Oberhalb der Auftragswalze 2 befindet sich eine Andruck-Einrichtung 8, mittels der eine einseitig kaschierte Wellpappe-Bahn 9 gegen die Auf-Above the application roller 2 there is a pressure device 8, by means of which a corrugated cardboard web 9 laminated on one side is pressed against the application roller.

tragswalze 2 gedrückt wird. Die Wellpappe-Bahn 9 weist eine gewellte Papierbahn 10 und eine Kaschierbahn 11, ebenfalls aus Papier, auf. Die Wellpappe-Bahn 9 ist in einer üblichen Maschine zur Herstellung von einseitig kaschierter Wellpappe hergestellt worden, wie sie beispielsweise aus der DE 195 36 007 Al (entsprechend GB 2 305 675 B) bekannt ist.The corrugated cardboard web 9 has a corrugated paper web 10 and a laminated web 11, also made of paper. The corrugated cardboard web 9 has been produced in a conventional machine for producing single-sided laminated corrugated cardboard, as is known for example from DE 195 36 007 A1 (corresponding to GB 2 305 675 B).

Die Wellpappe-Bahn 9 wird so über die Auftragswalze 2 geführt, daß die untenliegenden Spitzen 12 der gewellten Papierbahn 10 auf der Auftragswalze 2 beleimt werden, so daß die Wellpappe-Bahn 9 in einer in Arbeitsrichtung 13 nachgeordneten Vorrichtung beispielsweise mit einer unteren Deckbahn kaschiert oder mit einer weiteren Wellpappe-Bahn zusammengeführt und verbunden werden kann. Derartige Vorrichtungen sind beispielsweise aus der PCT-Anmeldung EP 99/04 147 bekannt. An der Berührungsstelle 14 zwischen den Spitzen 12 der Wellpappe-Bahn 9 und der Auftragswalze 2 entspricht die Drehrichtung 15 und die Geschwindigkeit der Auftragswalze 2 der Richtung und Geschwindigkeit der Wellpappe-Bahn 9 in Arbeitsrichtung 13.The corrugated cardboard web 9 is guided over the application roller 2 in such a way that the lower tips 12 of the corrugated paper web 10 are glued on the application roller 2, so that the corrugated cardboard web 9 can be laminated with a lower cover sheet or brought together and connected with another corrugated cardboard web in a device arranged downstream in the working direction 13. Such devices are known, for example, from the PCT application EP 99/04 147. At the contact point 14 between the tips 12 of the corrugated cardboard web 9 and the application roller 2, the direction of rotation 15 and the speed of the application roller 2 correspond to the direction and speed of the corrugated cardboard web 9 in the working direction 13.

Die Andruck-Einrichtung 8 weist einen Rahmen 16 auf, der auf der Einlaufseite 17 der Wellpappe-Bahn 9 um eine Achse 18 schwenkbar ist. Um diese Achse 18 ist auch eine Umlenkrolle 19 drehbar gelagert.The pressure device 8 has a frame 16 which can be pivoted about an axis 18 on the inlet side 17 of the corrugated cardboard web 9. A deflection roller 19 is also rotatably mounted about this axis 18.

An der Auslaufseite 20 der Wellpappe-Bahn 9 ist am Rahmen 16 eine Antriebsrolle 21 gelagert, die mittels eines nicht dargestellten, am Rahmen 16 angebrachten Servo-Antriebs antreibbar ist. Etwa in der Mitte des im wesentlichen horizontal angeordneten Rahmen 16 ist eine im wesentlichen in der Horizontalen und/oder der Vertikalen verstellbare Spannwalze 22 gelagert. Um die Umlenkrolle 19, die Antriebsrolle 21 und die Spannwalze 22On the outlet side 20 of the corrugated cardboard web 9, a drive roller 21 is mounted on the frame 16, which can be driven by means of a servo drive (not shown) attached to the frame 16. Approximately in the middle of the essentially horizontally arranged frame 16, a tension roller 22 is mounted, which can be adjusted essentially horizontally and/or vertically. In order to move the deflection roller 19, the drive roller 21 and the tension roller 22

ist ein endloses Band 23 gefuhrt. Die Rollen 19, 21 und die Walze 22 erstrecken sich über die volle Breite des Bandes 23. Das Band 23 ist bevorzugt als Sieb-Band ausgeführt. Bevorzugt weist es also eine Vielzahl von verhältnismäßig kleinen öffnungen auf, die aus einer geschlossenen Bandfläche ausgestanzt sein können. Das Band kann aber auch gewebt oder gewirkt sein. Als Werkstoff kommt insbesondere ein geeigneter Kunststoff in Betracht, beispielsweise Polyester oder Polyamid. Die mit ihrer Kaschierbahn 11 gegen das Untertrum 24 des Bandes 23 anliegende Wellpappe-Bahn 9 wird mit ihren Spitzen 12 gegen die Auftragswalze 2 gedrückt.an endless belt 23 is guided. The rollers 19, 21 and the roller 22 extend over the full width of the belt 23. The belt 23 is preferably designed as a screen belt. It therefore preferably has a large number of relatively small openings that can be punched out of a closed belt surface. The belt can also be woven or knitted. A suitable plastic, for example polyester or polyamide, is particularly suitable as the material. The corrugated cardboard web 9, which rests with its lamination web 11 against the lower run 24 of the belt 23, is pressed with its tips 12 against the application roller 2.

Zur Außerbetriebsetzung der Andruck-Einrichtung 8 kann der Rahmen 16 um die Achse 18 in die in der Zeichnung gestrichelt dargestellte Position hochgeschwenkt werden. In der Arbeitsstellung kann der Rahmen 16 fest verriegelt sein. Eine Regelung der Spannung des Bandes 23 erfolgt über die Spannwalze 22.To deactivate the pressure device 8, the frame 16 can be pivoted up about the axis 18 into the position shown in dashed lines in the drawing. In the working position, the frame 16 can be firmly locked. The tension of the belt 23 is regulated via the tension roller 22.

Zur Reinigung des Bandes 23, und zwar insbesondere des Sieb-Bandes 23, von Leim, insbesondere im Randbereich, sind innerhalb des Bandes 23 am Rahmen 16 Wasserdüsen 25 vorgesehen.
20For cleaning the belt 23, and in particular the sieve belt 23, of glue, in particular in the edge area, water nozzles 25 are provided within the belt 23 on the frame 16.
