Abstract

The doctor roll has a rotating roll (14) in a roll bed (12), both of which extend transversely across the width of the machine. A device (20) bears against the back of the roll bed in order to press the roll against a coating roller (8) or directly against the web of prod. as it passes over a support roll. The doctor roll and the roll bed form part of a modular system such that the roll can be exchanged with another of different dia., and the roll bed can be correspondingly exchanged for another so that the axes of rolls of different dia. take up the same position relative to the carrier beam (10).

Description

Die Erfindung betrifft eine Rollrakel-Baugruppe mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen. Bekanntlich dient eine Rollrakel in einer Streichmaschine, die zum Beschichten einer laufenden Bahn (z.B. Papierbahn) dient, in erster Linie als Dosierelement. Dabei wird die Rollrakel mit einer genau einstellbaren Anpreßkraft gegen eine Auftragswalze oder unmittelbar gegen die über eine Stützwalze laufende Bahn angedrückt, so daß von der zuvor aufgetragenen flüssigen Beschichtungsmasse nur ein Teil auf der Auftragswalze bzw. auf der Bahn verbleibt, wobei der überschüssige Flüssigkeitsanteil zurückgewiesen wird.The invention relates to a doctor blade assembly with the in The preamble of claim 1 features specified. generally known serves a doctor blade in a coating machine, which is used for Coating a running web (e.g. paper web) is used in primarily as a dosing element. The roller squeegee is included a precisely adjustable contact pressure against an application roller or directly against the web running over a backup roller pressed so that of the previously applied liquid coating composition only a part on the application roller or on the web remains, with the excess liquid portion is rejected.

Eine bekannte Rollrakel-Baugruppe ist beschrieben in DE 43 08 302 A1 (PA 05053).A known roller doctor blade assembly is described in DE 43 08 302 A1 (PA 05053).

Der Erfindung liegt die Aufgabe zugrunde, die bekannte Rollrakel-Baugruppe dahingehend weiterzuentwickeln, daß ein drehbarer Rakelstab, der einen vorgegebenen Außendurchmesser aufweist, ausgetauscht werden kann gegen einen Rakelstab mit einem anderen Durchmesser; ein solcher Austausch soll möglichst rasch und mit möglichst geringem Aufwand möglich sein.The invention has for its object the known doctor blade assembly to further develop that a rotatable Doctor rod, which has a predetermined outer diameter, can be exchanged for a doctor rod with a other diameter; such an exchange should be as possible be possible quickly and with as little effort as possible.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmale gelöst.This object is achieved by the in the characterizing part of the claim 1 specified features solved.

Ein wichtiger Erfindungsgedanke besteht darin, daß nach dem Austausch eines Rakelstabes gegen einen anderen mit abweichendem Durchmesser die Drehachse des "neuen" Rakelstabes sich in der gleichen Position relativ zum Tragbalken befindet wie die Drehachse des bisherigen Rakelstabes. Dadurch gewinnt man den Vorteil, daß die Position des Rakelstab-Antriebes unverändert bleibt. An important idea of the invention is that after the Exchange of a doctor rod for another with a different one The axis of rotation of the "new" doctor rod is in the same position relative to the support beam as that Rotation axis of the previous doctor rod. This way you win the Advantage that the position of the doctor rod drive remains unchanged remains.

Gemäß Anspruch 2 wird zusätzlich dafür gesorgt, daß auch die Position der Anpreßvorrichtung unverändert bleibt.According to claim 2, it is also ensured that the Position of the pressing device remains unchanged.

Weitere zweckmäßige Maßnahmen sind in den zusätzlichen Unteransprüchen angegeben.Further appropriate measures are in the additional subclaims specified.

Ausführungsbeispiele der Erfindung sind in den beigefügten schematischen Querschnitten (Figuren 1 und 2) dargestellt.Embodiments of the invention are in the accompanying schematic cross sections (Figures 1 and 2) shown.

Die Figur 1 zeigt mit vollen Linien eine Rollrakel-Baugruppe mit Rakelstab 14 mit einem relativ großen Rakelstab-Durchmesser D. Zusätzlich ist dort mit strichpunktierten Linien eine geänderte Rollrakel-Baugruppe (Rakelstab 14') mit kleinerem Rakelstab-Durchmesser d dargestellt. Wie man sieht unterscheiden sich die beiden Rollrakel-Baugruppen in nur sehr wenigen Details. Insbesondere sind die Positionen der Drehachsen der beiden Rakelstäbe 14 und 14', bezogen auf den Tragkörper 10, deckungsgleich. Ebenso befindet sich in beiden Varianten die rückwärtige Außenseite 9 des jeweiligen Rakelbettes 12 im gleichen Abstand vom Tragkörper 10.FIG. 1 shows a roller doctor blade assembly with solid lines with doctor rod 14 with a relatively large doctor rod diameter D. In addition there is with dash-dotted lines a modified roller doctor blade assembly (doctor rod 14 ') with smaller doctor rod diameter d shown. As you can see the two roller doctor blade assemblies differ only very much few details. In particular, the positions of the axes of rotation of the two doctor rods 14 and 14 ', based on the Support body 10, congruent. Also located in both Variants the rear outside 9 of the respective doctor bed 12 at the same distance from the supporting body 10.

Eines der wesentlichen Elemente der Rollrakel-Baugruppe ist der schon erwähnte (und nur teilweise sichtbare) Tragkörper 10, der sich quer durch die Maschine erstreckt. Er ist in bekannter Weise relativ zu der Walze 8 verschwenkbar. Die Walze 8 kann eine Auftragswalze sein, auf der ein Streichmassefilm gebildet wird, den die Walze an einer nicht sichtbaren Stelle auf eine Papierbahn überträgt. Die Walze 8 kann jedoch auch die zu beschichtende Papierbahn unmittelbar an der Rollrakel-Baugruppe vorbeiführen. In dem schon erwähnten Rakelbett 12 ist ein Rakelstab 14 drehbar gelagert. Das Rakelbett 12 ist mittels einer Fußleiste 16, welche hier die Form einer Klinge aufweist, und mittels eines aufblasbaren Klemmschlauches 18 im Tragkörper 10 befestigt. Abweichend hiervon kann auch ein einteiliges Rakelbett mit angeformter Fußleiste verwendet werden. Bei Druckentlastung des Klemmschlauches 18 kann das Rakelbett 12 zusammen mit dem Rakelstab 14 und der Fußleiste 16 aus dem Tragkörper 10 entfernt werden. One of the essential elements of the squeegee assembly is the already mentioned (and only partially visible) support body 10, which extends across the machine. He is well known Way pivotable relative to the roller 8. The roller 8 can be an applicator roller on which a coating film is formed, the roller in an invisible place transferred to a paper web. However, the roller 8 can also the paper web to be coated directly on the roll doctor assembly lead past. In the doctor bed 12 already mentioned a doctor rod 14 is rotatably mounted. The doctor bed 12 is by means of a baseboard 16, which here is in the form of a blade has, and by means of an inflatable clamping hose 18 in Support body 10 attached. Deviating from this can also be a one-piece Doctor bed with molded skirting board can be used. With pressure relief of the clamping hose 18, the doctor bed can 12 together with the doctor bar 14 and the baseboard 16 from the Support body 10 are removed.

Weitere bekannte Elemente sind eine Anpreßvorrichtung mit einem ebenfalls aufblasbaren Druckschlauch 20, der in einer Andrückleiste 22 abgestützt ist. Diese ist ihrerseits mittels zahlreicher über die Bahnbreite verteilt angeordneten und einzeln verstellbaren Spindeln 24 gegen den Tragkörper 10 abgestützt. Diese Einrichtung dient in bekannter Weise zum Erzielen eines möglichst gleichmäßigen Querprofils der Dicke der aufgetragenen Beschichtung.Other known elements are a pressing device with a also inflatable pressure hose 20, which is in a pressure bar 22 is supported. This in turn is by means of numerous and arranged individually across the width of the web adjustable spindles 24 supported against the support body 10. This device is used to achieve in a known manner a cross section of the thickness of the, which is as uniform as possible applied coating.

Nahe dem oberen Ende der rückwärtigen Außenseite 9 kann ein zusätzlicher Druckschlauch 26 vorgesehen sein, um die Flanken des Rakelbettes an den Rakelstab zu drücken (Abdichten der Schmiernuten).Near the upper end of the rear outer side 9, a additional pressure hose 26 may be provided around the flanks of the doctor bed against the doctor rod (sealing the Lubrication).

Will man beispielsweise anstelle des Rakelstabes 14 mit Durchmesser D einen Rakelstab 14' mit kleineren Durchmesser d einsetzen, so braucht man im wesentlichen (außer dem Rakelstab) nur das Rakelbett 12 gegen das Rakelbett 12' auszutauschen. In der Regel unterscheiden sich die beiden Rakelbetten 12 und 12' (außer durch die unterschiedlichen Lagerdurchmesser) nur durch die unterschiedlichen, bei 12 und 12' angedeuteten oberen Begrenzungsflächen. Da sich bei einem solchen Rakelstabwechsel der Abstand zwischen der Walze 8 und dem Tragkörper 10 ändert, müssen in der Regel auch die Formatschilde 30 durch solche mit geänderten Abmessungen ausgetauscht werden; oder man entfernt vom Formatschild 30 ein Verlängerungsstück 30a. Bei der Stauleiste 28 können wahlweise die in den Ansprüchen 3, 4 oder 5 angegebenen Maßnahmen getroffen werden.If you want, for example, instead of the doctor rod 14 with a diameter D insert a doctor rod 14 'with a smaller diameter d, so essentially you need (except the doctor rod) only to replace the doctor bed 12 with the doctor bed 12 '. In the two doctor beds 12 and 12 'generally differ (except due to the different bearing diameters) only through the different upper boundary surfaces indicated at 12 and 12 '. Because with such a doctor bar change the distance between the roller 8 and the support body 10 changes, usually also have the format plates 30 with such changed dimensions are exchanged; or you remove an extension piece 30a from the format label 30. In the Storage bar 28 can either in claims 3, 4 or 5 specified measures are taken.

Es sei noch erwähnt, daß das Rakelbett 12 mit dem Rakelstab 14, die Stauleiste 28 und die Formatschilde 30 eine Auftragskammer begrenzen, in welche ein Zuführkanal 32 für die flüssige Beschichtungsmasse einmündet.It should also be mentioned that the doctor bed 12 with the doctor rod 14, the storage bar 28 and the format plates 30 an order chamber limit in which a feed channel 32 for the liquid Coating mass flows out.

In Figur 2 sind die unveränderten Bauelemente mit den gleichen Bezugszahlen versehen wie in Figur 1. Es ist hier ein Rakelstab 14" mit noch weiter verkleinertem Durchmesser eingebaut, zusammen mit einem daran angepaßten Rakelbett 12" und mit einer verlängerten Fußleiste 16'. Der zusätzliche Druckschlauch 26 bleibt in diesem Fall wirkungslos. Dargestellt ist noch eine verkürzte Stauleiste 28. Die ebenfalls angepaßten Formatschilde sind in Figur 2 weggelassen.In Figure 2, the unchanged components are the same Reference numbers as in Figure 1. Here is a doctor rod 14 "with an even smaller diameter installed, together with a matching doctor blade bed 12 "and with an extended skirting board 16 '. The additional pressure hose 26 remains ineffective in this case. Is shown another shortened storage bar 28. The also adapted Format labels are omitted in Figure 2.
