Description

Die Erfindung betrifft das On-line-Behandeln in Form von Streichen, Pigmentieren oder Leimen oder sonstiger Beschichtung von laufenden Bahnen, insbesondere aus Papier oder Karton. Dabei ist die Streicheinrichtung der aus Trockenzylindern bestehenden Trockengruppe einer Papiermaschine zugeordnet.The invention relates to on-line treatment in the form of brushing, pigmenting or gluing or other coating of running webs, in particular of paper or cardboard. The coating device is assigned to the drying group consisting of drying cylinders of a paper machine.

Die Aufgabe der Erfindung ist es, eine raumsparende derartige Einrichtung anzugeben, wobei auch eine Umgehung der Beschichtungseinrichtung möglich sein soll. Dabei soll der Umgehungsweg möglichst einfach gebaut und kurz sein.The object of the invention is to provide a space-saving device of this type, it also being possible to bypass the coating device. The bypass route should be as simple as possible and short.

Gemäß der Erfindung wird gegebenenfalls nur eine geringe Vergrößerung der gesamten Maschinenlänge erforderlich, so daß sie sich insbesondere für Umbauten bestehender Papiermaschinen eignet. Es wird eine Umschaltung der Bahnführung innerhalb eines Bereichs, der höchstens zwei Durchmessern der Trockenzylinder entspricht, vorgesehen und die Streicheinrichtung praktisch oberhalb dieses Zwischenraumes angeordnet. Vor der Streicheinrichtung befinden sich dann vorzugsweise Trockner, die vorzugsweise auf der Basis von Infrarotstrahlung oder Heißluft arbeiten. Bei bestehenden Papiermaschinen ist praktisch nur nötig, zwei benachbarte Trockenzylinder zu entfernen und in dem entstehenden freien Raum die nötigen Leitrollen für die Bahn vorzusehen.According to the invention, only a slight increase in the total machine length may be required, so that it is particularly suitable for conversions to existing paper machines. The web guide is switched over within an area that corresponds to at most two diameters of the drying cylinders, and the coating device is arranged practically above this space. Dryers are then preferably located in front of the coating device, which preferably operate on the basis of infrared radiation or hot air. With existing paper machines it is practically only necessary to remove two adjacent drying cylinders and to provide the necessary guide rollers for the web in the free space that is created.

Nachfolgend wird die Erfindung anhand des in der Zeichnung dargestellten Ausführungsbeispieles erläutert.The invention is explained below using the exemplary embodiment shown in the drawing.

In der Figur sind von der Trockenzylindergruppe nur die Zylinder 46, 49 und 50 dargestellt, die in ihrer Numerierung auch ihrer zahlenmäßig fortlaufenden Nummern in der Papiermaschine entsprechen können. Die Bahnführung in dem Zwischenraum zwischen den beiden Zylindern 46 und 49 erfolgt entweder über die Leitrollen 16 und 17, falls die Streicheinrichtung umgangen wird oder über die Leitrollen 16, 18 und 19, um die Bahn der Streicheinrichtung zuzuführen. Es ist klar, daß es sich dabei vorzugsweise um Bahnen aus Papier oder Karton handelt.In the figure, only the cylinders 46, 49 and 50 of the drying cylinder group are shown, the numbering of which can also correspond to their numerical consecutive numbers in the paper machine. The web guide in the space between the two cylinders 46 and 49 takes place either via the guide rollers 16 and 17 if the coating device is bypassed or via the guide rollers 16, 18 and 19 in order to feed the web to the coating device. It is clear that these are preferably sheets of paper or cardboard.

Die Streicheinrichtung besteht hier vorzugsweise aus zwei miteinander einen Preßspalt bildenden Preßwalzen oder Bahnführungswalzen 1 und 2. Ihnen ist jeweils ein Streichauftragswerk 3 bzw. 3' zugeordnet, die im wesentlichen gleich aufgebaut und spiegelbildlich angeordnet sind. Jedes Auftragswerk kann aus einer Streichklinge oder einem ähnlich aufgebauten Halter 5 für ein Bett 7 einer Rollrakel 6 sowie einer in Bewegungsrichtung der Mantelfläche der Preßwalzen vorgeschalteten Drosselplatte 8 bestehen, wobei zwischen diesen Teilen ein Auftragsraum für die Streichmasse oder allgemein Beschichtungsmasse gebildet ist, der vorzugsweise unter überatmosphärischem Druck steht, und dem die Streichmasse aus einer Beschichtungskammer 9 zuführbar ist. Der Streicheinrichtung sind Heizeinrichtungen 51, 52 und 53 nachgeschaltet, die auf Infrarotbasis oder mit Heißluft arbeiten können.The coating device here preferably consists of two press rolls or web guide rolls 1 and 2 which form a press nip with one another. Each of them is assigned a coating application unit 3 or 3 ', which are constructed essentially identically and are arranged in mirror image. Each application unit can consist of a doctor blade or a similarly constructed holder 5 for a bed 7 of a doctor blade 6 and a throttle plate 8 connected upstream in the direction of movement of the outer surface of the press rolls, an application space for the coating slip or general coating compound being formed between these parts, which is preferably under is above atmospheric pressure, and to which the coating slip can be fed from a coating chamber 9. The coating device is followed by heating devices 51, 52 and 53 which can work on an infrared basis or with hot air.

Weitere Umlenkwalzen 21 - 23 führen dann die gestrichene und wieder vorgetrocknete Bahn den restlichen Trockenzylindern 49, 50 und folgende zu, damit die Bahn vollständig getrocknet wird.Further deflecting rollers 21-23 then feed the coated and pre-dried web to the remaining drying cylinders 49, 50 and the following, so that the web is completely dried.

Es ist klar, daß die Streicheinrichtung erst zu einem Zeitpunkt eingesetzt werden kann, wenn die Bahn bereits einen erheblichen Trockengehalt hat, der mindestens 75, vorzugsweise mindestens 80 % beträgt.It is clear that the coating device can only be used at a time when the web already has a considerable dry content, which is at least 75, preferably at least 80%.

Die Streicheinrichtung eignet sich dazu, die Bahn mit Leim zu imprägnieren oder auch mit Pigment zu beschichten. Ein Feuchtemeßgerät 40 ist zwischen die Leitrollen 16 und 18 eingebaut.The coating device is suitable for impregnating the web with glue or for coating it with pigment. A moisture meter 40 is between the idlers 16 and 18th built-in.

Die Streicheinrichtung mit den Walzen 1 und 2 ist vorzugsweise auf einem höheren Maschinenflur bzw. einem eine Etage höher angeordneten Maschinenfundament angeordnet, als sich die Trockenzylindergruppe befindet.The coating device with the rollers 1 and 2 is preferably arranged on a higher machine floor or on a machine foundation arranged one floor higher than the drying cylinder group.

Bei der erfindungsgemäßen Einrichtung hat man vorzugsweise einen sehr kurzen Weg bei der Umgehung der Streicheinrichtung, weil ja der Abstand zwischen den am zu der Streicheinrichtung führenden Zwischenraum angeordneten Trockenzylinder höchstens zwei Durchmesser derselben in der Länge - bezogen auf die Reihenanordnung der Trockenzylinder - beträgt.In the device according to the invention, there is preferably a very short way of bypassing the coating device, because the distance between the drying cylinders arranged at the space leading to the coating device is at most two diameters in length - based on the row arrangement of the drying cylinders.

Der große Vorteil der Anordnung ist auch, daß bei einem Bahnabriß - falls vorzugsweise an der Streichmaschine - die Bahn vor ihrem Neu-Einfädeln ohne weiteres in den Keller gefahren werden kann. Bei Betrieb ohne Streichmaschine verliert man bei einem Umbau nur die Heizleistung der zwei - nicht mehr vorhandenen - Trockenzylinder 47 und 48.The great advantage of the arrangement is also that in the event of a web break - if preferably on the coating machine - the web can be easily driven into the basement before it is re-threaded. When operating without a coating machine, you only lose the heating power of the two - no longer available - drying cylinders 47 and 48 during a conversion.
