Definitions
- roller applicators with these characteristics have been in use for a long time and are therefore generally known. Such devices have to meet certain conditions: The application roller and the counter roller must be completely rigid so that a uniform coating of the material passing through is guaranteed over the entire web width. This condition is met in the known applicators by appropriate dimensioning of the diameter and wall thickness of the applicator roller and the counter roller.
- the counter roller being part of a set of three rollers counter roller set, in which the roller counter in rolling contact with it two rigid press rolls at a short distance and at least approximately horizontal level next to each other on the guide and bearing blocks are vertically movable together with the counter roll and adjustable with the desired pressure on the applicator roll.
- the counter roller is supported against bending, so that a uniform coating of the material passing through is guaranteed over the entire web width.
- this roller arrangement has the disadvantage that the counter-roller can practically not be removed separately from the roller set and exchanged for another one.
- the counter roller should not come into contact with the coating liquid. Their width must therefore be matched to the width of the sheet or sheet material to be coated. When the counter roll protrudes laterally beyond the material surface to be coated, its edges become coated with the coating liquid contaminated, this contamination being transferred to subsequent rollers.
- the surface of the counter roll must have a more or less hard to soft elastic surface adapted to the coating substance. Since various types of sheet or sheet-like materials are to be coated with different substances with such an application unit, it is necessary that a number of counter-rollers with different widths are available. Of course, the counter roller must be interchangeably mounted in the applicator.
- the invention is therefore based on the object of improving a roller applicator of the type defined in the introduction to the description and in the preamble of claim 1 in such a way that the deficiencies described of the known applicator mechanisms of this type are eliminated.
- the counter-roller should be light, be able to be kept available in a large number of designs with different surfaces and in different widths at the lowest possible cost, and be easy and quick to replace without great effort in manual work and technical aids.
- the accumulation wave of the coating liquid should be kept as short as possible before the inlet between the application roller and the material web to be coated, which improves the uniformity of the coating.
- a trough 3 for receiving a coating liquid is arranged in the lower region on a trough support 2 and a scoop roller 4 immersed in the trough 3 is mounted above it.
- the position of the tub support 2 is vertically adjustable by means of a hand spindle 5 .
- the tub 3 is easily removable on the tub support 2 and is exchangeably attached to another tub.
- the scoop roller 4 has a structured surface. It is associated with a doctor device 6 for wiping off excess coating liquid.
- the side walls 1 of the machine frame each have a vertical guide and bearing block 7 .
- application roller 8 is adjustably supported against the scoop roller.
- a counter-roller set is arranged above it, which can be moved by means of a plurality of cylinder drives in the vertical guide of the guide and bearing blocks 7 against the application roller 8 .
- the counter-roller set consists of three rollers, namely two shape-identical, rigid press rollers 9 , 10 , which are mounted parallel and next to each other in a horizontal plane at a slightly greater distance above the applicator roller 8 and one between the applicator roller 8 and the two press rollers 9 , 10 mounted counter roller 11 .
- the counter roll 11 is guided at both ends between the vertical bearing plates 13, which are each part of which is arranged on the guide blocks 7 mountings for the counter-roller. 11 It has a stub axle 14 with a central depression at each end. In each of them there is a front bearing ball 15 which rotates with the counter roller 11 on the adjacent bearing plate 13 of the holder.
- the brackets for the counter roller 11 each consist of two movably connected parts, namely a bracket part 16 fastened to the adjacent guide and bearing block 7 and a device on the free inside of which is rotatably mounted about an axis 17 which runs parallel to the counter roller 11 and at a distance from the latter for lateral guidance and Lift the counter roller 11 from its working position.
- Each of these at both ends of the counter roll 11 provided means for laterally guiding and lifting of the counter-roller 11 has a around the axis 17 pivotally mounted on Konsolteil 16, oriented perpendicular to the axis 17 of the bearing plate eighteenth
- Konsolteil 16 oriented perpendicular to the axis 17 of the bearing plate eighteenth
- two bearing journals 19 , 20 with conventional ball bearings 19a , 20a are arranged, the axes of which are directed parallel to the counter roller 11 and on which these rests with their stub axles 14 .
- the bearing plate 18 is designed as a central part of a two-armed lever pivotable about the axis 17 .
- the short lever arm 21 is connected by a tension spring 22 to a downward arm 23 fastened to the bracket part 16 .
- the long lever arm opposite the short lever arm forms an operating lever 24 .
- the guide and bearing blocks 7 holding the counter-roller set 9 , 10 , 11 are vertically movable by means of several cylinder drives on the side walls 1 of the machine frame, so that the counter-roller set 9 , 10 , 11 from the applicator roller 8 or from the web running over it 12 of the material to be coated can be lifted off. Then, after depressing the operating lever 24, the counter roller 11 can be easily removed and another one inserted.
- the counter roller 11 consists of a light core tube 11a , which is closed at both ends by end walls 11b with the stub axles 14 and is surrounded by a jacket 11c made of a different material.
- the jacket 11c can, depending on the type the coating liquid and / or the material to be coated consist of more or less soft rubber, plastic or other material. Its surface can be smooth or textured. It can also be more or less shorter than the core tube 11a , its length depending on the width of the material web or sheet to be coated.
- the counter-roller 11 is practically not subjected to bending, since it bears under the rigid pressure rollers 9 , 10 over the entire length of its jacket 11c and is pressed only by this onto the web of the material to be coated which runs over the application roller. It only has to withstand the pressure of the press rolls 9 , 10 without permanent deformation. Therefore, compared to the counter rolls in the known applicators, it can be built much more easily and, in terms of production costs, considerably cheaper. It is therefore much cheaper to keep a larger range of counter-rollers with different surfaces and different shell widths available. Due to the low weight, the replacement of the counter rollers can be carried out effortlessly with little manual work, even without technical aids.

Abstract
Description
Die Erfindung betrifft ein Walzen-Auftragwerk zum Beschichten von durchlaufendem bahn- oder tafelförmigem Material mit einem in flüssigem Zustand aufzutragenden Beschichtungsmittel, wobei
- im unteren Bereich zwischen zwei Seitenwänden eines Maschinengestells über einer Wanne zur Bereithaltung der aufzutragenden Beschichtungsflüssigkeit eine in diese eintauchende Schöpfwalze und darüber eine auf der Schöpfwalze abrollende Auftragwalze gelagert sind und
- über der Auftragwalze wenigstens eine die zu beschichtende Materialbahn oder -tafel gegen die Auftragwalze niederdrückende und auf dieser abrollende Gegenwalze auswechselbar zwischen zwei an den Seitenwänden des Maschinengestells angeordneten Führungs- und Lagerblöcken gelagert ist, deren Abstand zur Auftragwalze veränderbar ist.
- in the lower region between two side walls of a machine frame, above a trough for holding the coating liquid to be applied, a scoop roller which is immersed in it and above which an application roller rolling on the scoop roller are stored and
- Above the applicator roller, at least one counter-roller, which presses the material web or sheet to be coated against the applicator roller and rolls on it, is interchangeably mounted between two guide and bearing blocks arranged on the side walls of the machine frame, the distance from which can be changed from the applicator roller.
Walzen-Auftragwerke mit diesen Merkmalen sind bereits seit langem im Gebrauch und daher allgemein bekannt. Solche Vorrichtungen haben bestimmte Bedingungen zu erfüllen:
Die Auftragwalze und die Gegenwalze müssen völlig biegesteif sein, damit eine über die ganze Bahnbreite gleichmäßige Beschichtung des durchlaufenden Materials gewährleistet ist. Diese Bedingung wird bei den bekannten Auftragwerken durch entsprechende Dimensionierung der Durchmesser und der Wandstärken der Auftragwalze und der Gegenwalze erfüllt.Roller applicators with these characteristics have been in use for a long time and are therefore generally known. Such devices have to meet certain conditions:
The application roller and the counter roller must be completely rigid so that a uniform coating of the material passing through is guaranteed over the entire web width. This condition is met in the known applicators by appropriate dimensioning of the diameter and wall thickness of the applicator roller and the counter roller.
Aus der DE-PS 272 473 geht eine Maschine zum Bedrucken von Stoffen (Geweben, Papier o.dgl.) in Bahnen hervor, wobei die Gegenwalze Bestandteil eines aus drei Walzen bestehenden Gegenwalzen-Satzes ist, in dem über der Gegenwalze in Rollkontakt mit dieser zwei biegesteife Preßwalzen in geringem Abstand und wenigstens annähernd waagerechter Ebene nebeneinander an den Führungs- und Lagerblöcken gemeinsam mit der Gegenwalze vertikal beweglich und mit gewünschtem Druck auf die Auftragwalze einstellbar gelagert sind. Damit ist zwar die Gegenwalze gegen Durchbiegen abgestützt, so daß eine über die ganze Bahnbreite gleichmäßige Beschichtung des durchlaufenden Materials gewährleistet ist. Dieser Walzenanordnung haftet aber der Nachteil an, daß die Gegenwalze praktisch nicht separat aus dem Walzensatz herausgenommen und gegen eine andere ausgetauscht werden kann.From DE-PS 272 473 a machine for printing on fabrics (fabrics, paper or the like) emerges in webs, the counter roller being part of a set of three rollers counter roller set, in which the roller counter in rolling contact with it two rigid press rolls at a short distance and at least approximately horizontal level next to each other on the guide and bearing blocks are vertically movable together with the counter roll and adjustable with the desired pressure on the applicator roll. Thus, the counter roller is supported against bending, so that a uniform coating of the material passing through is guaranteed over the entire web width. However, this roller arrangement has the disadvantage that the counter-roller can practically not be removed separately from the roller set and exchanged for another one.
Die Gegenwalze soll mit der Beschichtungsflüssigkeit nicht in Berührung kommen. Ihre Breite muß daher mit der Breite des zu beschichtenden bahn- oder tafelförmigen Materials abgestimmt sein. Wenn die Gegenwalze seitlich über die zu beschichtende Materialfläche hinausragt, werden ihre Ränder mit der Beschichtungsflüssigkeit verunreinigt, wobei diese Verunreinigung auf nachfolgende Walzen übertragen wird.The counter roller should not come into contact with the coating liquid. Their width must therefore be matched to the width of the sheet or sheet material to be coated. When the counter roll protrudes laterally beyond the material surface to be coated, its edges become coated with the coating liquid contaminated, this contamination being transferred to subsequent rollers.
Die Oberfläche der Gegenwalze muß eine der Beschichtungssubstanz angepaßte mehr oder weniger harte bis weichelastische Oberfläche haben. Da mit einem solchen Auftragwerk verschiedenartige bahn- oder tafelförmige Materialien mit verschiedenen Substanzen beschichtet werden sollen, ist es erforderlich, daß eine Reihe von Gegenwalzen mit einerseits verschiedenen Breiten verfügbar ist. Dabei muß natürlich die Gegenwalze auswechselbar im Auftragwerk gelagert sein.The surface of the counter roll must have a more or less hard to soft elastic surface adapted to the coating substance. Since various types of sheet or sheet-like materials are to be coated with different substances with such an application unit, it is necessary that a number of counter-rollers with different widths are available. Of course, the counter roller must be interchangeably mounted in the applicator.
Daraus ergibt sich eine Reihe von Unvollkommenheiten bei den bekannten Auftragwerken:
Es ist ein erheblicher Aufwand an manueller Arbeit und technischen Hilfsmitteln erforderlich, um die Gegenwalze auszuwechseln, die wegen der üblicherweise erforderlichen Formstabilität sehr schwer ist.
Die Verfügbarkeit einer Reihe von Gegenwalzen mit verschiedenen Oberflächen und verschiedenen Breiten ist sehr kostspielig, dies um so mehr, je vielseitiger die Einsatzmöglichkeiten eines solchen Auftragwerkes sein sollen.
Eine Gegenwalze mit verhältnismäßig großem Durchmesser bewirkt eine lange Stauwelle der Beschichtungsflüssigkeit vor dem Einlauf zwischen Auftragwalze und der unter der Gegenwalze anliegenden Materialbahn. Dadurch wird die Gleichmäßigkeit der Beschichtung beeinträchtigt.This results in a number of imperfections in the known commissioned works:
A considerable amount of manual work and technical aids are required to complete the Replace counter roll, which is very difficult due to the usually required dimensional stability.
The availability of a number of counter rolls with different surfaces and different widths is very expensive, and the more varied the possible uses of such a coating unit, the more so.
A counter roller with a relatively large diameter causes a long accumulation wave of the coating liquid before the inlet between the application roller and the material web lying under the counter roller. This affects the uniformity of the coating.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Walzen-Auftragwerk der in der Beschreibungseinleitung und im Oberbegriff des Anspruchs 1 definierten Gattung so zu verbessern, daß die beschriebenen Mängel der bekannten Auftragwerke dieser Art beseitigt sind. Insbesondere soll die Gegenwalze leicht sein, in einer Vielzahl von Ausführungen mit verschiedenen Oberflächen und in verschiedenen Breiten bei geringstmöglichem Kostenaufwand verfügbar gehalten werden können sowie einfach und schnell ohne großen Aufwand an manueller Arbeit und technischen Hilfsmitteln auswechselbar sein. Dabei soll die Stauwelle der Beschichtungsflüssigkeit vor dem Einlauf zwischen der Auftragwalze und der zu beschichtenden Materialbahn möglichst kurz gehalten werden, was die Gleichmäßigkeit der Beschichtung verbessert.The invention is therefore based on the object of improving a roller applicator of the type defined in the introduction to the description and in the preamble of
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein solches Auftragwerk mit den Merkmalen gemäß dem kennzeichnenden Teil des Anspruchs 1 ausgestattet ist.
Weitere Einzelheiten der Erfindung und alternative Detail-Lösungsvorschläge gehen aus den Ansprüchen 2 bis 10 hervor.The stated object is achieved in that such an application is equipped with the features according to the characterizing part of

Zwischen zwei Seitenwänden 1 eines Maschinengestells sind im unteren Bereich auf einem Wannenträger 2 eine Wanne 3 zur Aufnahme einer Beschichtungsflüssigkeit angeordnet und darüber eine in die Wanne 3 eintauchende Schöpfwalze 4 gelagert. Die Position des Wannenträgers 2 ist mittels Handspindel 5 vertikal verstellbar. Die Wanne 3 ist auf dem Wannenträger 2 leicht abnehmbar und gegen eine andere Wanne austauschbar befestigt. Die Schöpfwalze 4 hat eine strukturierte Oberfläche. Ihrist eine Rakeleinrichtung 6 zum Abstreifen überschüssiger Beschichtungsflüssigkeit zugeordnet.Between two
Oberhalb der Schöpfwalze 4 haben die Seitenwände 1 des Maschinengestells je einen vertikalen Führungs- und Lagerblock 7. In dessen unterem Bereich ist eine auf der Schöpfwalze 4 abrollende Auftragwalze 8 gegen die Schöpfwalze 4 verstellbar gelagert. Darüber ist ein Gegenwalzen-Satz angeordnet, der mittels mehrerer Zylindertriebe in der vertikalen Führung der Führungs- und Lagerblöcke 7 gegen die Auftragwalze 8 beweglich ist.
Der Gegenwalzen-Satz besteht aus drei Walzen, nämlich aus zwei formgleichen, biegesteifen Preßwalzen 9, 10, die in geringem Abstand parallel nebeneinander in waagerechter Ebene in etwas größerem Abstand über der Auftragwalze 8 gelagert sind und einer zwischen der Auftragwalze 8 und den beiden Preßwalzen 9, 10 gelagerten Gegenwalze 11. Diese wird von den beiden Preßwalzen 9, 10 gegen die Auftragwalze 8 niedergedrückt, wobei sie einerseits unter den Preßwalzen 9, 10 und andererseits auf der über die Auftragwalze 8 laufenden Bahn 12 des zu beschichtenden Materials abrollt.Above the
The counter-roller set consists of three rollers, namely two shape-identical,
Die Gegenwalze 11 ist an beiden Stirnseiten zwischen senkrechten Lagerscheiben 13 geführt, die jeweils Bestandteil der an den Führungsblöcken 7 angeordneten Halterungen für die Gegenwalze 11 sind. Sie hat an jedem Stirnende einen Achsstummel 14 mit einer zentralen Vertiefung. Darin befindet sich je eine Stirnlager-Kugel 15, die sich mit der Gegenwalze 11 an der benachbarten Lagerscheibe 13 der Halterung dreht.The
Die Halterungen für die Gegenwalze 11 bestehen jeweils aus zwei beweglich miteinander verbundenen Teilen, nämlich einem an dem benachbarten Führungs- und Lagerblock 7 befestigten Konsolteil 16 und einer an dessen freier Innenseite um eine parallel zur Gegenwalze 11 im Abstand von dieser verlaufende Achse 17 drehbar gelagerten Einrichtung zur seitlichen Führung und zum Ausheben der Gegenwalze 11 aus ihrer Arbeitsposition. Jede dieser an beiden Stirnenden der Gegenwalze 11 vorgesehenen Einrichtungen zum seitlichen Führen und Ausheben der Gegenwalze 11 hat eine um die Achse 17 am Konsolteil 16 schwenkbar gelagerte, senkrecht zur Achse 17 gerichtete Lagerplatte 18. An dieser sind auf der der Gegenwalze 11 zugewandten Seite im Bereich des benachbarten Achsstummels 14 die Lagerscheibe 13 und darunter in geringem Abstand nebeneinander zwei Lagerzapfen 19, 20 mit handelsüblichen Kugellagern 19a, 20a angeordnet, deren Achsen parallel zur Gegenwalze 11 gerichtet sind und auf denen diese mit ihren Achsstummeln 14 ruht.The brackets for the
Die Lagerplatte 18 ist als Mittelteil eines zweiarmigen um die Achse 17 schwenkbaren Hebels ausgebildet. Der kurze Hebelarm 21 ist durch eine Zugfeder 22 mit einem am Konsolteil 16 befestigten, nach unten gerichteten Ausleger 23 verbunden. Der dem kurzen Hebelarm gegenüber befindliche lange Hebelarm bildet einen Bedienungshebel 24.
Die den Gegenwalzen-Satz 9, 10, 11 haltenden Führungs- und Lagerblöcke 7 sind mittels mehrerer Zylindertriebe an den Seitenwänden 1 des Maschinengestells vertikal beweglich, womit der Gegenwalzen-Satz 9, 10, 11 von der Auftragwalze 8 bzw. von der darüber laufenden Bahn 12 des zu beschichtenden Materials abgehoben werden kann. Dann läßt sich nach Niederdrücken des Bedienungshebels 24 die Gegenwalze 11 leicht herausnehmen und eine andere einsetzen.The bearing

Bei diesem Ausführungsbeispiel besteht die Gegenwalze 11 aus einem leichten Kernrohr 11a, welches an beiden Enden durch Stirnwände 11b mit den Achsstummeln 14 verschlossen und von einem Mantel 11c aus einem anderen Material umgeben ist. Der Mantel 11c kann je nach Art der Beschichtungsflüssigkeit und/oder des zu beschichtenden Materials aus mehr oder weniger weichem Gummi, Kunststoff oder anderem Material bestehen. Seine Oberfläche kann glatt oder strukturiert sein. Er kann auch mehr oder weniger kürzer als das Kernrohr 11a sein, wobei sich seine Länge nach der Breite der zu beschichtenden Materialbahn oder -tafel richtet.In this embodiment, the
Die Gegenwalze 11 wird praktisch nicht auf Biegung beansprucht, da sie in der ganzen Länge ihres Mantels 11c unter den biegesteifen Preßwalzen 9, 10 anliegt und nur durch diese auf die über die Auftragwalze laufende Bahn des zu beschichtenden Materials niedergedrückt wird. Sie hat lediglich dem Druck der Preßwalzen 9, 10 ohne bleibende Verformung standzuhalten. Daher kann sie im Vergleich zu den Gegenwalzen in den bekannten Auftragwerken sehr viel leichter und hinsichtlich Herstellungskosten ganz erheblich billiger gebaut werden. Daher ist die Bereithaltung eines größeren Sortimentes von Gegenwalzen mit verschiedenen Oberflächen und verschiedenen Mantelbreiten auch sehr viel billiger.
Wegen des geringen Gewichtes kann das Auswechseln der Gegenwalzen mit geringem Aufwand an manueller Arbeit auch ohne technische Hilfsmittel mühelos durchgeführt werden.The counter-roller 11 is practically not subjected to bending, since it bears under the
Due to the low weight, the replacement of the counter rollers can be carried out effortlessly with little manual work, even without technical aids.
