Abstract
Description
Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device according to the generic term of claim 1.
Eine gattungsgemäße Vorrichtung ist bekannt aus Streichanlagen innerhalb einer Papier – Herstellungs- und/oder -Veredelungsmaschine. Dorf wird eine laufende Papier- oder Kartonbahn beispielsweise mit Streichfarbe (pigmenthaltige, wässrige Suspension), Stärke oder einer Imprägnierlösung versehen.A generic device is known from coating systems within a paper manufacturing and / or finishing machine. Dorf, for example, is using a running paper or cardboard web Coating color (pigmented, watery Suspension), starch or an impregnation solution.
Beim indirekten Auftrag wird das genannte Medium auf die Oberfläche einer Walze oder auch eines umlaufenden flexiblen Bandes aufgebracht, um von da aus auf die Faserstoffbahn übertragen zu werden.With an indirect order, this will be named medium on the surface applied to a roller or a rotating flexible belt, to be transferred from there to the fibrous web.
Oftmals erfolgt dieses indirekte Auftragen simultan auf beide Bahnseiten, wobei zwei solcher Walzen oder Bänder miteinander einen Nip bilden, durch den die Faserstoffbahn läuft und das aufgebrachte Medium empfängt.This is often done indirectly Apply simultaneously to both sides of the web, using two such rollers or ribbons together form a nip through which the fibrous web runs and the applied medium receives.
Es ist aber auch möglich nur eine der beiden Bahnseiten zu beschichten. In diesem Fall wird das nicht benutzte Auftragswerk einfach von der Auftragswalze abgeschwenkt.But it is also only possible to coat one of the two sides of the web. In this case it won't used application unit simply swung away from the application roller.
Genauso ist es auch möglich, eine Bahnseite indirekt, wie eben beschrieben, und die andere Seite auf direktem Wege zu beschichten.It is also possible to use one Track side indirectly, as just described, and the other side on to coat directly.
Nachdem die Faserstoffbahn das Auftragsmedium empfangen hat, läuft diese einer Umlenkeinrichtung zu.After the fibrous web is the application medium received, is running this to a deflection device.
Dabei ist eine relativ lange freie Strecke, die als freier Bahnzug bezeichnet wird, zu überwinden. In dieser freien Strecke neigt die Bahn besonders zum Flattern und zur Faltenbildung.There is a relatively long free one To cover the route known as the free train. In this free stretch, the train tends to flutter and for wrinkling.
Bei bekannten Maschinen ist vor allem aus konstruktiven Gründen der Abstand, also der freie Bahnzug, mindestens doppelt so groß, wie der Durchmesser der Auftragswalze misst.In known machines, above all for design reasons the distance, i.e. the free path, at least twice as large as the diameter the application roller measures.
Der Erfindung liegt die Aufgabe zugrunde, mit einer geeigneten Vorrichtung den freien Bahnzug zu verkürzen und dadurch die Bahn besser als bisher stabilisieren zu können.The invention is based, with a suitable device to shorten the free web train and thereby being able to stabilize the railway better than before.
Erfindungsgemäß wird die Aufgabe durch die im Anspruch 1 genannten Merkmale gelöst.According to the invention, the object is achieved by solved in claim 1 features.
Die Bahnumlenkeinrichtung rückt durch die erfindungsgemäß ausgeführte Konstruktion näher an die betreffende Auftragswalze, von der die Bahn das Auftragsmedium empfangen hat, heran.The web deflector moves through the construction carried out according to the invention closer to the relevant application roller from which the web receives the application medium has.
Neben einem verkürzten, freien Bahnzug und geringerem Platzbedarf wird das Flattern der Bahn und deren Faltenbildung vermieden, zumindest aber minimiert.In addition to a shortened, free train and less Space requirements prevent the web from fluttering and wrinkling, at least minimized.
Ein weiterer Vorteil besteht im verringerten Aufwand für die Bereitstellung einer Tragkonstruktion der Bahnumlenkeinrichtung, da diese Tragfunktion mit vom Tragbalken des Auftragsaggregates übernommen wird.Another advantage is the reduced effort for the Provision of a supporting structure for the web deflection device, since this supporting function is also taken over by the supporting beam of the application unit becomes.
In Ausgestaltung der Erfindung ist vorgesehen, dass der Abstand zwischen der Auftragswalze und der Bahnumlenkeinrichtung – gemessen von der Mittelachse der Auftragswalze – kleiner als 2 × D, vorzugsweise nur 1,5 × D beträgt, wobei D der Durchmesser der Auftragswalze ist.In an embodiment of the invention provided that the distance between the applicator roller and the Web deflection device - measured from the central axis of the application roller - less than 2 × D, preferably only 1.5 × D is, where D is the diameter of the applicator roller.
Es soll erwähnt sein, dass die Bahnumlenkeinrichtung ein sogenannter, handelsüblicher Airturn oder Aircan ist, der mit seinen Heißluftstrahlen die frisch beschichtete Bahn ohne diese zu beschädigen berührungslos führt, d.h. stützt und umlenkt und gleichzeitig auch vortrocknet.It should be mentioned that the web deflection device a so-called, commercially available Airturn or Aircan is the one that is freshly coated with its hot air jets Non-contact web without damaging it leads, i.e. supports and redirects and pre-dries at the same time.
Die erfindungsgemäße Vorrichtung ist überall dort einsetzbar, wo beengte Raumverhältnisse, vor allem bei Umbauten von bestehenden Papier- und/oder Streichmaschinen herrschen oder wo besonders zugempfindliche (altpapierhaltige) Papiere zu behandeln sind.The device according to the invention is everywhere there can be used where space is limited especially when converting existing paper and / or coating machines prevail or where particularly sensitive (waste paper) papers are to be treated.

It is only approx 1.5 × D, resulting in better web guidance than previously achievable.
