Description

Die Erfindung betrifft eine Vorrichtung zum Verschwenken und Justieren einer Funktionseinheit innerhalb einer Streichmaschine zum Auftragen eines flüssigen bis pastösen Mediums auf eine laufende Oberfläche, wobei die laufende Oberfläche bei direktem Auftrag die Oberfläche einer Papier-, Karton- oder anderen Faserstoffbahn und bei indirektem Auftrag die Oberfläche eines Übertragselementes, beispielsweise eine Auftragswalze ist, welches das Auftragsmedium an die Oberfläche der Faserstoffbahn überträgt.The invention relates to a device for pivoting and adjusting a functional unit within a coating machine for applying a liquid to pasty medium on a running surface, the running surface for direct application, the surface of a paper, cardboard or other fibrous web and indirect application, the surface a transfer element, for example an applicator roll, which transfers the application medium to the surface of the fibrous web.

Bekanntermaßen ist es erforderlich, eine Funktionseinheit (z.B. eine Auftragseinrichtung oder eine Rakeleinrichtung) innerhalb einer Streichmaschine verschwenkbar anzuordnen, um eine Betriebs- bzw. Bereitschaftsposition und eine Serviceposition für Reinigung und Wartung der Funktionseinheit erreichen zu können. Außerdem ist es erforderlich eine bestimmte Feineinstellung, beispielsweise eine Winkeleinstellung vorzunehmen, z.B. um den Auftragswinkel des flüssigen oder pastösen Mediums auf die laufende Oberfläche oder den Anstellwinkel eines Rakelelementes in Abhängigkeit vom Material der Faserstoffbahn, der Art des Mediums, der Laufgeschwindigkeit der Bahn oder dergleichen Betriebsparamtern einzustellen.As is known, it is necessary to pivotally position a functional unit (e.g., applicator or squeegee device) within a coater to achieve a service and readiness position and service position for cleaning and maintaining the functional unit. In addition, it is necessary to make a certain fine adjustment, for example an angle adjustment, e.g. to adjust the application angle of the liquid or pasty medium on the running surface or the angle of attack of a doctor element depending on the material of the fibrous web, the type of medium, the running speed of the web or the like Betriebssparamtern.

Bisher erfolgte das Verschwenken der Funktionseinheit mit einem Elektrohubzylinder, mit dem das Verschwenken sowie auch eine Feineinstellung möglich war. Dieser Elektrohubzylinder war allerdings schwierig zu händeln, nur aufwändig ansteuerbar, schwierig zu warten und fiel außerdem häufig aus.So far, the pivoting of the functional unit with a Elektrohubzylinder, with the pivoting and a fine adjustment was possible. However, this Elektrohubzylinder was difficult to handle, only consuming to control, difficult to maintain and also fell out frequently.

Für das Verschwenken und die Feineinstellung wurden auch separat voneinander angeordnete und betriebene Elemente, mit jeweils eigenen Schwenkhebeln, eingesetzt. Dies bedeutete einen sehr hohen Platzbedarf und hohen apparatetechnischen und Ansteuerungs- Aufwand.For pivoting and fine adjustment also separately arranged and operated elements were used, each with its own pivoting levers. This meant a very high space requirement and high equipment engineering and Ansteuerungs- effort.

Demgegenüber ist es Aufgabe der Erfindung, eine Vorrichtung anzugeben, die kostengünstiger herstellbar, platzsparend und einfacher ansteuerbar ist und darüberhinaus betriebssicher arbeitet.In contrast, it is an object of the invention to provide a device which is less expensive to produce, space-saving and easier to control and also works reliable.

Diese Aufgabe wird erfindungsgemäß bei einer gattungsgemäßen Vorrichtung dadurch gelöst, dass ein an sich bekannter Hydraulikzylinder zum Verschwenken der Funktionseinheit in eine Betriebs- bzw. Bereitschaftsposition und eine abgeschwenkte Service - bzw. Reinigungsposition vorgesehen ist, wobei im ausgefahrenen Zustand des Hydraulikzylinders die Betriebs- bzw. Bereitschaftsposition und im eingefahrenen Zustand des Hydraulikzylinders eine Service- bzw. Reinigungsposition einstellbar ist, und wobei auf den Hydraulikzylinder in dessen axialer Verlängerung ein an sich bekanntes Spindelhubelement aufgesetzt ist, welches die Feinjustierung der Funktionseinheit übernimmt.This object is achieved in a generic device in that a known hydraulic cylinder for pivoting the functional unit is provided in an operating or standby position and a pivoted service - or cleaning position, wherein in the extended state of the hydraulic cylinder operating or Standby position and in the retracted state of the hydraulic cylinder, a service or cleaning position is adjustable, and wherein a per se known Spindelhubelement is placed on the hydraulic cylinder in the axial extension, which takes over the fine adjustment of the functional unit.

Eine solche Vorrichtung zeichnet sich durch kostengünstige Herstellung, einfache Ansteuerbarkeit, betriebssicheres Arbeiten und auch einfache Wartung aus. Die zur Verschwenkung und zur Feinjustierung vorgesehenen Elemente sind jeweils handelsübliche Bauteile, die bisher nur separat eingesetzt wurden.Such a device is characterized by cost-effective production, easy controllability, reliable operation and easy maintenance. The provided for pivoting and fine adjustment elements are each commercially available components that were previously used only separately.

Die Erfinder haben erkannt, dass durch die erfindungsgemäße Kombination beider Bauteile zu einer einzigen Verstellvorrichtung eine sehr kompakte und vor allem Platz sparende Vorrichtung geschaffen werden kann.The inventors have recognized that a very compact and above all space-saving device can be created by the inventive combination of both components to a single adjustment.

Die Erfindung lässt sich vor allem in Streichmaschinen einsetzen, wo als Funktionseinheit ein Auftragswerk zum Aufbringen des Mediums und/oder eine in Laufrichtung der laufenden Oberfläche nachgeordnete Rakeleinrichtung zum Abrakeln oder nur Egalisieren des aufgebrachten Mediums vorgesehen ist.The invention can be used above all in coating machines, where as a functional unit a commissioning unit for applying the medium and / or a downstream in the running direction of the running surface doctor device for doctoring or only leveling of the applied medium is provided.

In Ausgestaltung der Erfindung kann es zweckmäßig sein, wenn das Spindelhubelement eine Gewindespindel aufweist, welche in die Kolbenstange des Hydraulikzylinders an dessen Stangenkopf eingeschraubt ist. In die Kolbenstange braucht dann nur ein entsprechendes Gegengewinde eingearbeitet werden. Auf einfachste Weise wird so eine kompakte Verstellvorrichtung geschaffen.In an embodiment of the invention, it may be expedient if the Spindelhubelement has a threaded spindle which is screwed into the piston rod of the hydraulic cylinder at the rod end. In the piston rod then only a corresponding mating thread needs to be incorporated. On easiest way a compact adjustment is created.

Ein Alternative dazu kann auch darin bestehen, dass die Spindel des Spindelhubelementes am Zylinderboden des Hydraulikzylinders befestigt ist.
Eine weitere Alternative kann auch darin bestehen, dass das Spindelhubelement nicht am Kopfteil in die Kolbenstange des Hydraulikzylinders eingeschraubt ist, sondern mit Hilfe eines Zwischenstückes oder Flansches am Boden des Hydraulikzylinders befestigt ist. Die gesamte Verstelleinheit weist dann an beiden Enden je ein Gelenkauge auf.An alternative to this may also be that the spindle of the Spindelhubelementes is attached to the cylinder bottom of the hydraulic cylinder.
Another alternative may also be that the Spindelhubelement is not screwed to the head part in the piston rod of the hydraulic cylinder, but is fixed by means of an intermediate piece or flange at the bottom of the hydraulic cylinder. The entire adjustment then has at both ends depending on a joint eye.

Eine sehr einfache Lösung für das Verschwenken der Funktionseinheit besteht darin, dass der Hydraulikzylinder einschließlich des aufgesetzten Spindelhubelementes einerseits an einer ersten Lagerstelle, die sich an einem Schwenkhebel des Tragkörpers der Funktionseinheit oder an einem Stuhlungsteil der Streichmaschine befindet und andererseits an einer zweiten Lagerstelle, die sich direkt an der Funktionseinheit befindet, gelenkig gelagert ist. Zusätzliche Schwenkhebel, wie beim Stand der Technik bei getrennter Ausführung, sind hierbei nicht notwendig.A very simple solution for pivoting the functional unit is that the hydraulic cylinder including the attached Spindelhubelementes on the one hand at a first bearing point, which is located on a pivot lever of the support body of the functional unit or on a Funging part of the coating machine and on the other hand at a second bearing point, the located directly on the functional unit, is articulated. Additional pivoting levers, as in the prior art in separate execution, are not necessary here.

Sehr zweckmäßig ist es, wenn im Rahmen der Erfindung die vom Spindelhubelement vorzunehmende Feinjustierung der Funktionseinheit, zur Einstellung des Auftragswinkels für das vom Auftragswerk abzugebende Mediums vorgesehen ist. Dabei spielt es keine Rolle welcher Art das Auftragswerk ist. Am geeignetsten sind kontaktlos wirkende Auftragswerke, wie sogenannte Düsenauftragswerke, mit denen ein freier und ungestützter Strahl, aber auch ein im freien Fall abgegebener Vorhang auf die oftmals bis zu 12m breite und schnelllaufende Oberfläche (Auftragselemet, z. B. Auftragswalze bei indirektem Auftrag oder Faserstoffbahn bei direktem Auftrag) aufgebracht werden soll.It is very useful if, within the scope of the invention, the fine adjustment of the functional unit to be made by the spindle lifting element is provided for adjusting the application angle for the medium to be delivered by the applicator. It does not matter what kind the commission is. Most suitable are non-contact applicators, such as so-called nozzle applicators, with which a free and unsupported beam, but also a free-fall curtain on the often up to 12m wide and high-speed surface (Auftragselemet, eg applicator roll for indirect application or fibrous web for direct order) should be applied.

Ein weitere zweckmäßige Feinjustierung mit dem aufgesetzten Spindelhubelement kann im Rahmen der Erfindung auch zur Einstellung des Anstellwinkels des in der Rakeleinrichtung eingesetzten Rakelelementes dienen.Another useful fine adjustment with the attached Spindelhubelement can also serve to adjust the angle of attack of the doctor blade used in the doctor device in the context of the invention.

In Ausgestaltung der Erfindung kann vorgesehen sein, dass das aufgesetzteSpindelhubelement motorisch oder per Hand über ein Handrad, eine Kurbel oder eine Ratsche betätigbar ist. Das Betätigen kann aufgrund seiner Anordnung am Kopf des Hydraulikzylinders leicht von der Bedienerseite her erfolgen.In an embodiment of the invention it can be provided that the attached Spindelhubelement motor or by hand via a handwheel, a crank or a ratchet is actuated. The operation can be done easily from the operator side due to its location on the head of the hydraulic cylinder.

Die Erfindung soll im Folgenden an Hand der beigefügten Figuren näher erläutert werden:The invention will be explained in more detail below with reference to the attached figures:

In Figur 1 ist die erfindungsgemäße Verstelleinrichtung 1 dargestellt. Sie besteht aus einer Kombination aus einem handelsüblichen Hydraulikzylinder 2, wobei in axialer Verlängerung des Hydraulikzylinders 2 ein ebenso handelsübliches Spindelhubelement 3 zur Verstellung einer Funktionseinheit 4 aufgesetzt ist.FIG. 1 shows the adjusting device 1 according to the invention. It consists of a combination of a commercially available hydraulic cylinder 2, wherein in the axial extension of the hydraulic cylinder 2, a commercially available Spindelhubelement 3 is placed for adjusting a functional unit 4.

Der Hydraulikzylinder 2 besteht wiederum aus dem Hohlzylinder 2a mit seinem Zylinderboden 2b und einer aus dem Inneren des Hohlzylinders 2a ausfahrbaren Kolbenstange 2c. Verbunden ist das Spindelhubelement 3 mit dem Kopf 2d der Kolbenstange 2c des Hydraulikzylinders 2, wobei die Spindel 3a des Spindelhubelementes 3 in ein eingearbeitetes Gegengewinde 2f der Kolbenstange 2c des Hydraulikzylinders 2 eingeschraubt ist. Mit 2g ist eine erste und mit 2g' eine zweite Lagerstelle - bzw. Anlenkstelle des Hydraulikzylinders 2 bezeichnet. Beide Lagerstellen befinden sich auf derselben Achse x. Die Lagerstelle 2g befindet sich in einem sogenannten Gelenkauge 2h, während die zweite Lagerstelle 2g' sich in einer Gelenkgabel 2i befindet.The hydraulic cylinder 2 in turn consists of the hollow cylinder 2 a with its cylinder base 2 b and a piston rod 2 c which can be extended from the interior of the hollow cylinder 2 a. Connected is the Spindelhubelement 3 with the head 2d of the piston rod 2c of the hydraulic cylinder 2, wherein the spindle 3a of the Spindelhubelementes 3 is screwed into an incorporated mating thread 2f of the piston rod 2c of the hydraulic cylinder 2. 2g designates a first and 2g 'a second bearing point or articulation point of the hydraulic cylinder 2. Both Bearings are on the same axis x. The bearing 2g is located in a so-called joint eye 2h, while the second bearing 2g 'is located in a yoke 2i.

Das Spindelhubelement weist auch eine Winkelanzeige 3b auf, die zur Feinjustierung bzw. zur Einstellung eines gewünschten Winkels der Funktionseinheit 4 gegenüber der laufenden Oberfläche 5 nutzbar ist. Beispielsweise lässt sich damit einfacher der Auftragswinkel bei einem Auftragswerk oder ein Anpresswinkel eines verwendeten Rakelelementes, z.B. einer Rakelklinge einstellen.The screw jack also has an angle indicator 3b, which can be used for fine adjustment or for setting a desired angle of the functional unit 4 with respect to the running surface 5. For example, this makes it easier to measure the application angle at a commissioned unit or a contact angle of a doctor element used, e.g. set a doctor blade.

Eine weitere, allerdings nicht dargestellte Ausführung wäre denkbar, indem das Spindelhubelement nicht am Kopf 2d angeschraubt, sondern über ein nicht dargestelltes Zwischenstück oder einen Flansch am anderen Endes des Hydraulikzylinders, und zwar am Boden 2b, befestigt würde. Hierbei ist das Spindelehubelement ebenfalls in axialer Verlängerung aufgesetzt. Anstelle der in Figur 1 gezeigten Gelenkgabel 2i wäre dann an dieser Stelle ebenfalls ein Gelenkauge 2h angebracht.Another, but not shown embodiment would be conceivable by the Spindelhubelement not screwed to the head 2d, but via an unillustrated adapter or a flange at the other end of the hydraulic cylinder, namely at the bottom 2b, would be attached. Here, the Spindelehubelement is also placed in the axial extension. Instead of the joint fork 2i shown in FIG. 1, a joint eye 2h would then also be attached at this point.

In der Figur 2 ist als Funktionseinheit 4 innerhalb einer Streichmaschine ein Düsenauftragswerk 4.1 dargestellt, welches sich gerade in Bereitschafts- bzw. Betriebsposition I befindet. Das Auftragswerk 4.1. ist einer laufenden Oberfläche 5 zugeordnet, die im Beispiel die Oberfläche einer drehenden Stützwalze 5' sein soll, über die in Laufrichtung L im Betrieb der Streichmaschine eine Faserstoffbahn 6, bestehend aus Papier oder Karton läuft. Diese Bahn 6 soll mit einem flüssigen bis pastösen Medium M, beispielsweise pigmenthaltige Streichfarbe, beschichtet werden. Mit 4.2 ist die Düse des Auftragswerkes 4.1. bezeichnet, die in der Betriebsposition I annähernd radial zur Faserstoffbahn 6 hin (bei direktem Auftrag bzw. bei indirektem Auftrag auf eine Auftragswalze 5", die in einem nicht dargestellten Nip das Medium an die Faserstoffbahn abgibt) gerichtet ist. Für abspritzendes Medium M ist neben bzw. unterhalb der Düse 4.2 außerdem noch eine Auffangwanne 4.3 vorhanden, die in der Betriebsposition annähernd senkrecht steht. In dieser in Figur 2 gezeigten Bereitschafts- bzw. Betriebsposition I befindet sich der Hydraulikzylinder 2 im ausgefahrenen Zustand.In the figure 2 is shown as a functional unit 4 within a coating machine, a nozzle applicator 4.1, which is currently in standby or operating position I. The commissioned work 4.1. is associated with a running surface 5, which should be in the example, the surface of a rotating support roller 5 ', over which runs in the direction L in the operation of the coating machine, a fibrous web 6, consisting of paper or cardboard. This web 6 should be coated with a liquid to pasty medium M, for example, pigment-containing coating color. 4.2, the nozzle of the commissioned work 4.1. is denoted in the operating position I approximately radially to the fibrous web 6 toward (direct order or indirect order on an applicator roll 5 ", which emits the medium in a nip, not shown, the medium to the fibrous web.) For ejecting medium M is next In addition, there is also a collecting trough 4.3, which is approximately vertical in the operating position, below the nozzle 4.2 In this standby or operating position I shown in FIG extended state.

Gelagert ist der Hydraulikzylinder 2 bzw. die gesamte Verstelleinrichtung 1 zum Einen an einer ersten Lagerstelle 2g. Diese erste Lagerstelle 2g befindet sich in Nähe des Zylinderbodens 2b an einem Schwenkhebel 7 des Tragkörpers bzw. einem Stuhlungsteil 8 der Funktionseinheit 4 bzw. der Streichmaschine. Zum Anderen ist die Verstelleinrichtung 1 auch an einer zweiten Lagerstelle 2g' gelagert, die sich entgegengesetzt zur ersten Lagerstelle 2g direkt an der Funktionseinheit 4 und in Nähe des Spindelhubelementes 3 befindet. Die Lagerstellen 2g und 2g' befinden sich auf ein und derselben Achse x.The hydraulic cylinder 2 or the entire adjusting device 1 is stored on the one hand at a first bearing 2g. This first bearing 2g is located in the vicinity of the cylinder base 2b on a pivoting lever 7 of the supporting body or a stiffening part 8 of the functional unit 4 or the coating machine. On the other hand, the adjusting device 1 is also mounted on a second bearing 2g ', which is opposite to the first bearing 2g directly to the functional unit 4 and in the vicinity of the Spindelhubelementes 3. The bearings 2g and 2g 'are located on one and the same axis x.

Die Einstellung des gewünschten Auftragswinkels α wird im Beispiel mit dem Spindelhubelement 3, und zwar per Hand, über ein nicht dargestelltes Handrad vorgenommen. In der Figur 2 ist die mögliche Einstellrichtung mit einem gebogten Doppelpfeil oberhalb der Düse 4.2 dargestellt. Eine Winkelanzeige 3b erleichtert die genaue Einstellung.The setting of the desired job angle α is made in the example with the Spindelhubelement 3, by hand, via a handwheel, not shown. FIG. 2 shows the possible adjustment direction with a curved double arrow above the nozzle 4.2. An angle indicator 3b facilitates the exact adjustment.

Wird der Hydraulikzylinder dagegen eingefahren, so wie in Figur 3 dargestellt, so dreht sich das gesamte Auftragswerk 4.1 und die Düse 4.2 in Uhrzeigerrichtung nach unten, so dass von der Bedienseite B her das Reinigen oder Servicearbeiten für einzelne Bauteile, wie die annähernd nun waagerecht stehende Düse 4.2 und die Auffangwanne 4.3 möglich sind. Das Auftragswerk 4.1 befindet sich also in ServicePosition II.If, however, the hydraulic cylinder is retracted, as shown in FIG. 3, then the entire applicator unit 4.1 and nozzle 4.2 rotate clockwise downwards, so that cleaning or service work for individual components, such as the approximately horizontal position, is performed from the operating side B. Nozzle 4.2 and the drip tray 4.3 are possible. The commissioned work 4.1 is therefore in ServicePosition II.

Die übrigen Bauteile entsprechen jenen, die bei Figur 2 erläutert wurden und sollen hier deshalb nicht erneut beschrieben werden.The other components correspond to those which have been explained in FIG. 2 and will therefore not be described again here.
