To give a dosed feed of a fluid especially to a rotary printing press or varnishing machine, a liquid lubricant is fed at intervals on to the mantle surface of the application roller (15), before the chamber scraper system (16) in the direction of roller rotation, and at its sealing system (25). Each chamber scraper has an adjacent lubricator (17), with a feed pipe (18) and a switch valve (19) coupled to a control unit (20) or pulse generator.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Dosieren eines flüssigen Mediums in einer Verarbeitungsmaschine/ insbesondere in einer Rotationsdruckmaschine oder einer Lackiermaschine, nach den Oberbegriffen der unabhängigen Ansprüche.The invention relates to a method and a device for dosing a liquid medium in a processing machine / in particular in a rotary printing machine or a coating machine, according to the preambles of the independent claims.

[Stand der Technik][State of the art]

Eine Dosiervorrichtung dieser Art ist aus EP 0 071 180 A1 bekannt. Die Dosiervorrichtung besteht aus einem Kammerrakel, im Wesentlichen aus einem Gehäuse mit Seitenwänden und am Gehäuse angeordneten Rakelblättern gebildet, wobei ein erstes Rakelblatt als Arbeitsrakelblatt und ein zweites Rakelblatt als Schließrakelblatt angeordnet sind. Die Dosiervorrichtung enthält ferner eine Auftragwalze, auf der sich das Rakelsystem abstützt, so dass mit dem Gehäuse eine Kammer eingeschlossen ist. In die Kammer wird ein zu dosierendes flüssiges Medium mittels Zulauf eingespeist und überschüssiges Medium mittels Rücklaufleitung abgeführt.A metering device of this type is known from EP 0 071 180 A1. The metering device consists of a chambered doctor blade, essentially formed from a housing with side walls and doctor blades arranged on the housing, a first doctor blade being arranged as a working doctor blade and a second doctor blade being arranged as a closing doctor blade. The metering device also contains an applicator roller on which the doctor system is supported, so that a chamber is enclosed with the housing. A liquid medium to be dosed is fed into the chamber by means of an inlet and excess medium is discharged by means of a return line.

Aus EP 0 401 250 B1 ist ein Dosiersystem als Rakelsystem bekannt, dass im Bereich der Stirnseiten seitlich angeordnete und die Gehäusekammer verschließende Dichtungselemente (Seitendichtungen) aufweist. Die Dichtungselemente sind der Krümmung der zugeordneten Auftragwalze angepasst und bestehen aus elastischem bzw. elastomeren Material.EP 0 401 250 B1 discloses a metering system as a doctor blade system which has sealing elements (side seals) which are arranged laterally in the region of the end faces and close the housing chamber. The sealing elements are adapted to the curvature of the assigned application roller and consist of elastic or elastomeric material.

Weiterhin ist aus US-A 5,150,651 ein Dosiersystem als Rakelsystem mit Kammerrakel und zugeordneter Aniloxwalze bekannt. Dabei weist das Kammerrakel innerhalb der gebildeten Kammer zur Aufnahme von flüssigen Medien angeordnete Seitendichtungen auf. Diese Seitendichtungen weisen der benachbarten Walze zugeordnete, als Schmiertaschen wirkende Vertiefungen auf. Jede Schmierstofftasche ist zur Versorgung mit einer Schmierflüssigkeit mit einer Zuführleitung und einer Rücklaufleitung versehen.Furthermore, a metering system is known from US Pat. No. 5,150,651 as a doctor blade system with a chamber doctor blade and an associated anilox roller. The chambered doctor blade has side seals arranged within the chamber formed for receiving liquid media. These side seals have depressions that act as lubrication pockets and are assigned to the adjacent roller. Each lubricant pocket is for the supply of a lubricant provided with a feed line and a return line.

Aus DE 197 29 977 A1 ist ein Offsetdruckwerk zum Lackieren von Bedruckstoffen bekannt. Hierbei die Dosiervorrichtung durch ein Kammerrakelsystem und eine Auftragwalze gebildet, wobei das Kammerrakelsystem Seitendichtungen aufweist. Die Auftragwalze ist mit einem eine Druck-/Lackform tragenden Plattenzylinder in Kontakt und dem Plattenzylinder ist ein Gummituchzylinder benachbart zugeordnet.From DE 197 29 977 A1 an offset printing unit for coating printing materials is known. Here, the metering device is formed by a chambered doctor blade system and an application roller, the chambered doctor blade system having side seals. The applicator roller is in contact with a plate cylinder carrying a printing / lacquer form and a blanket cylinder is assigned adjacent to the plate cylinder.

Von Nachteil ist bei derartigen Ausbildungen, dass insbesondere an den Kontaktflächen von Seitendichtungen und zugeordneter Auftragwalze, abhängig von der Anpresskraft der Seitendichtungen, Reibungsmomente entstehen. Zusätzlich entstehen Reibungsmomente an den Kontaktflächen von Rakelblatt und zugeordneter Auftragwalze. Beim Auftreten von Reibungsmomenten tritt stets eine Energieumwandlung von irreversiblem Charakter auf, d.h. es entsteht primär Wärme sowie Abrieb.A disadvantage of such designs is that, in particular on the contact surfaces of side seals and the associated application roller, frictional moments occur, depending on the contact pressure of the side seals. In addition, there are moments of friction on the contact surfaces of the doctor blade and the associated applicator roller. When friction moments occur, an energy conversion of irreversible character always occurs, i.e. there is primarily heat and abrasion.

Bei Reduzierung des Anpressdruckes an den Kontaktflächen besteht die Gefahr, dass Leckagen auftreten und das zu verarbeitende Medium unkontrolliert in die Verarbeitungsmaschine austritt. Bei einer Versorgung von Schmierstofftaschen mit einem Schmierstoff besteht die Gefahr, dass der Schmierstoff sich mit dem zu verarbeitenden Medien vermischt.
Ist der Schmierstoff und das zu verarbeitende Medium identisch, so besteht die Gefahr, dass das zu verarbeitende Medium, insbesondere an den Seitendichtungen und Rakelblättern, teilweise auch am Gehäuse des Kammerrakels antrocknet bzw. auskristallisiert. Dabei treten an den Seitendichtungen Leckagen mit den bereits oben genannten Nachteilen auf, die Seitendichtungen altern frühzeitig und an den Rakelblättern und den Dichtungen tritt ein frühzeitiger Verschleiß auf.If the contact pressure on the contact surfaces is reduced, there is a risk that leakages will occur and the medium to be processed will escape into the processing machine in an uncontrolled manner. When lubricant bags are supplied with a lubricant, there is a risk that the lubricant will mix with the media to be processed.
If the lubricant and the medium to be processed are identical, there is a risk that the medium to be processed, in particular on the side seals and doctor blades, will also partially dry or crystallize on the housing of the chamber doctor blade. Leakage occurs on the side seals with the disadvantages already mentioned above, the side seals age prematurely and on the doctor blades and the seals there is premature wear.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art zu schaffen, die die genannten Nachteile vermeiden, die insbesondere im Bereich von Dichtungen und Rakelblättern eines eine Auftragwalze enthaltenden Dosiersystems ein verschleißarmes Dosieren gestatten und die Reibungsmomente spürbar reduzieren.The invention has for its object to provide a method and a device of the type mentioned, which avoid the disadvantages mentioned, which allow wear-free metering, in particular in the area of seals and doctor blades, and reduce the frictional moments noticeably.

Die Aufgabe wird erfindungsgemäß durch die Ausbildungsmerkmale der unabhängigen Ansprüche gelöst. Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.The object is achieved according to the invention by the training features of the independent claims. Further developments result from the dependent claims.

Ein erster Vorteil der Erfindung ist darin begründet, dass die Reibungsmomente an den Dichtungen (Dichtungssystemen) sowie den Rakelblättern, insbesondere im Bereich der den Dichtungssystemen benachbarten Rakelblätter, durch den Einsatz eines flüssigen Schmierstoffes reduziert ist.A first advantage of the invention is based on the fact that the frictional moments on the seals (sealing systems) and the doctor blades, in particular in the area of the doctor blades adjacent to the sealing systems, is reduced by the use of a liquid lubricant.

Vorteilhaft ist weiterhin, dass das Antrocknen bzw. Auskristallisieren des zu verarbeitenden flüssigen Mediums an den Rakelblättern und Dichtungssystemen spürbar vermeidbar ist. Damit ist auch die Dosierqualität des zu verarbeitenden flüssigen Mediums verbesserbar.It is also advantageous that the drying or crystallization of the liquid medium to be processed on the doctor blades and sealing systems is noticeably avoidable. This also improves the dosing quality of the liquid medium to be processed.

Ein weiterer Vorteil besteht darin, dass die Wärmeentwicklung in den Kontaktbereichen des Rakelsystems mit der zugeordneten Auftragwalze gering ist. Dies ist insbesondere bei höheren Umgebungstemperaturen, bedingt durch beispielsweise dem Rakelsystem benachbarte Trocknereinrichtungen und/oder bei hohen zu verarbeitenden Auflagen, vorteilhaft.Another advantage is that the heat development in the contact areas of the doctor system with the associated applicator roller is low. This is particularly advantageous at higher ambient temperatures, for example due to dryer devices adjacent to the doctor system and / or in the case of long runs to be processed.

Weiterhin ist von Vorteil, dass das Dosiersystem in Folge des reduzierbaren Verschleißes an den Dichtungssystemen und Rakelblättern höhere Standzeiten erzielt. Zusätzlich sind die Maschinenstandzeiten, beispielsweise bedingt durch Reinigungs- und Servicetätigkeiten, reduzierbar.Another advantage is that the metering system due to the wear on the sealing systems and Doctor blades have a longer service life. In addition, the machine downtimes can be reduced, for example due to cleaning and service activities.

Gemäß Figur 1 besteht eine in Reihenbauweise erstellte Bogenrotationsdruckmaschinen aus mehreren Druckwerken 1, gebildet aus Plattenzylinder 8 und Gummituchzylinder 9 sowie zumindest einem Farbwerk. In Förderrichtung 14 des Bogenmaterials folgen ein erstes Lackwerk 2, beispielsweise zwei Trocknereinrichtungen 4 und wenigstens ein zweites Lackwerk 3. Dem zweiten Beschichtungswerk 3 folgt ein Ausleger 5, welcher zumindest ein endlos umlaufendes Fördersystem 7 und einen Auslegerstapel 6 aufweist.According to FIG. 1, a sheet-fed rotary printing press produced in series consists of several printing units 1, formed from plate cylinder 8 and blanket cylinder 9 and at least one inking unit. A first coating unit 2, for example two drying devices 4 and at least one second coating unit 3, follow in the conveying direction 14 of the sheet material. The second coating unit 3 is followed by a delivery unit 5, which has at least one endless conveyor system 7 and a delivery stack 6.

Die Lackwerke 2, 3 weisen jeweils einen Formzylinder 12 sowie je eine Dosiervorrichtung 13 auf. Der Bogentransport wird mittels Bogenführungszylinder, speziell Transfertrommeln 10 und Druckzylinder 11, realisiert.The coating units 2, 3 each have a forme cylinder 12 and a metering device 13. The sheet is transported by means of sheet guiding cylinders, especially transfer drums 10 and printing cylinders 11.

Jede Dosiervorrichtung 13 weist eine Auftragwalze 15, insbesondere eine Rasterwalze auf, welche mit einem Kammerrakelsystem 16 gekoppelt ist. Das Kammerrakelsystem 16 weist ein sich achsparallel zur Auftragwalze 15 erstreckendes Gehäuse für die Aufnahme eines zu verarbeitenden flüssigen Mediums, beispielsweise Lack, auf und besteht ferner aus einem ersten Rakelblatt 24 (Schließrakel) und einem zweiten Rakelblatt 23 (Arbeitsrakel) sowie jeweils die derart gebildete Gehäusekammer seitlich begrenzenden Dichtungssystemen 25.Each metering device 13 has an application roller 15, in particular an anilox roller, which is coupled to a chamber doctor blade system 16. The chambered doctor blade system 16 has a housing extending axially parallel to the applicator roller 15 for receiving a liquid medium to be processed, for example lacquer, and furthermore consists of a first doctor blade 24 (closing doctor blade) and a second doctor blade 23 (working doctor blade) and the housing chamber formed in this way laterally delimiting sealing systems 25.

Die Rakelblätter 23, 24 stützen sich auf dem Walzenmantel der Auftragwalze 15 ab und das Kammerrakelsystem 16 ist mit wenigstens einer Zuführ- und einer Rücklaufleitung (Umlaufleitungssystem) für das zu verarbeitende flüssige Medium, beispielsweise Dispersionslack, gekoppelt.The doctor blades 23, 24 are supported on the roller jacket of the applicator roller 15 and the chamber doctor blade system 16 is coupled to at least one feed line and one return line (circulation line system) for the liquid medium to be processed, for example dispersion lacquer.

Das Kammerrakelsystem 16 weist Dichtungssysteme 25 auf, welche das Kammergehäuse begrenzen und mit der Auftragwalze 15 in Kontakt sind. Diese Kontaktstellen stellen Schmierstellen dar, denen jeweils ein Schmierstoffgeber 17, bevorzugt mit der Austrittsöffnung auf die Auftragwalze 15 gerichtet, benachbart zugeordnet ist.The chambered doctor blade system 16 has sealing systems 25 which limit the chamber housing and are in contact with the application roller 15. These contact points represent lubrication points to which a lubricant dispenser 17, preferably directed with the outlet opening onto the application roller 15, is assigned adjacent.

Bevorzugt ist in Drehrichtung der Auftragwalze 15 vor dem ersten Rakelblatt 24 (Schließrakel) des Kammerrakelsystems 16 wenigstens ein Schmierstoffgeber 17 angeordnet, welcher stets einem Dichtungssystem 25 (Schmierstelle) des Kammerrakelsystems 16 benachbart zugeordnet ist. D. h. jeder Schmierstelle ist ein Schmierstoffgeber 17 zugeordnet. Bevorzugt ist das Kammerrakelsystem 16 an beiden Enden mit zwei Dichtungssystemen 25 ausgebildet, so dass je ein Schmierstoffgeber 17 einem Dichtungssystem 25 benachbart zugeordnet sind.Preferably, in the direction of rotation of the application roller 15, at least one lubricant dispenser 17 is arranged in front of the first doctor blade 24 (closing doctor) of the chamber doctor system 16, which is always associated with a sealing system 25 (lubrication point) of the chamber doctor system 16. I.e. a lubricator 17 is assigned to each lubrication point. The chambered doctor blade system 16 is preferably formed at both ends with two sealing systems 25, so that one lubricant dispenser 17 is assigned to each sealing system 25.

Es sind weiterhin Kammerrakelsysteme 16 mit innerhalb der Gehäusekammer angeordneten Dichtungen bekannt (z.B. US 4 796 528). Bei derartigen Ausbildungen des Kammerrakelsystems 16 sind jedem endseitig angeordneten Dichtungssystem 25 sowie den innerhalb der Gehäusekammer angeordneten Dichtungen (Dichtungssystem 25) jeweils ein Schmierstoffgeber 17 benachbart zugeordnet. Bevorzugt sind die Schmierstoffgeber 17 mit einer
gestellfesten, achsparallel zur Auftragwalze 15 angeordneten Traverse 27 getriebetechnisch als Schubgelenk gepaart. Die Schmierstoffgeber 17 sind dabei in axialer Bewegungsrichtung 26 entlang der Traverse 27 verschiebbar. In einer weiteren Ausbildung sind die Schmierstoffgeber 17 zusätzlich um die Traverse 27 schwenkbar, so dass der Neigungswinkel jedes Schmierstoffgebers 17 zur Auftragwalze 15 bzw. zum Kammerrakelsystem 16 einstellbar ist. Alternativ zur Traverse 27 sind die Schmierstoffgeber 17 auch an einer Maschinenverschutzung (Innenseite) verschiebbar und schwenkbar anordenbar.Chamber doctor blade systems 16 with seals arranged inside the housing chamber are also known (for example US Pat. No. 4,796 528). In such configurations of the chambered doctor blade system 16, a lubricator 17 is assigned adjacent to each sealing system 25 arranged at the end and to the seals (sealing system 25) arranged within the housing chamber. The lubricators 17 are preferred with a
frame-fixed, axially parallel to the applicator roller 15 arranged traverse 27 paired technically as a sliding joint. The lubricant dispensers 17 can be displaced in the axial direction of movement 26 along the cross member 27. In a further embodiment, the lubricant dispensers 17 can additionally be pivoted about the cross member 27, so that the angle of inclination of each lubricant dispenser 17 to the application roller 15 or to the chambered doctor blade system 16 can be adjusted. As an alternative to the traverse 27, the lubricant dispensers 17 can also be slidably and pivotably arranged on a machine cover (inside).

An den Austrittsöffnungen der Schmierstoffgeber 17 ist der flüssige Schmierstoff, insbesondere ein Fluid, beispielsweise Wasser, kontinuierlich in sehr geringen Mengen oder bevorzugt in Intervallen auf den Walzenmantel der Auftragwalze 15 im Bereich der Kontaktstellen der Dichtungssysteme 25 abgebbar.At the outlet openings of the lubricant dispensers 17, the liquid lubricant, in particular a fluid, for example water, can be dispensed continuously in very small quantities or preferably at intervals onto the roller jacket of the application roller 15 in the region of the contact points of the sealing systems 25.

Jeder Schmierstoffgeber 17 ist mit einem Leitungssystem 18 gekoppelt, welches je ein Schaltventil 19 aufweist. Jedes Schaltventil 19 ist mit einer Steuerung 20 verbunden. Bevorzugt ist das Schaltventil 19 ein Impulsmagnetventil, welches mit einem Elektroimpuls von einigen Millisekunden (≤ 50 ms) betreibbar ist. Als Steuerung 20 ist bevorzugt eine Maschinensteuerung, alternativ ist ebenso ein Impulsgenerator, einsetzbar. Für die Schmierstoffversorgung von jedem Schmierstoffgeber 17 ist jedem Schaltventil 19 ein Zuführstrang 21 vorgeordnet und die Zuführstränge 21 weisen einen zentralen Anschluss 22 für den flüssigen Schmierstoff auf.Each lubricant dispenser 17 is coupled to a line system 18, which each has a switching valve 19. Each switching valve 19 is connected to a controller 20. The switching valve 19 is preferably a pulse solenoid valve which can be operated with an electrical pulse of a few milliseconds (50 50 ms). A machine controller is preferably used as the controller 20, alternatively a pulse generator can also be used. For the supply of lubricant to each lubricator 17, each switching valve 19 is preceded by a feed line 21 and the feed lines 21 have a central connection 22 for the liquid lubricant.

In einer weiteren Ausbildung ist jeder Schmierstoffgeber 17 mittels Leitungssystem 18 mit wenigstens einer zeitlich steuerbaren Pumpe (statt des Schaltventils 19) verbunden. Eine derartige Pumpe steuert sämtliche Schmierstoffgeber 17 oder alternativ ist jeder Schmierstoffgeber 17 mittels Leitungssystem 18 mit je einer zeitlich steuerbaren Pumpe ausführbar. Die Pumpe bzw. Pumpen ist bzw. sind mit einer Steuerung 20 verbunden. Die Steuerung 20 ist bevorzugt eine Maschinensteuerung oder ein Impulsgenerator. Der oder den Pumpen ist wenigstens ein Zuführstrang 21 mit einem Anschluss 22 vorgeordnet.In a further embodiment, each lubricator 17 is connected by means of a line system 18 to at least one time-controllable pump (instead of the switching valve 19). Such a pump controls all lubricant dispensers 17 or, alternatively, each lubricant dispenser 17 can be implemented by means of line system 18, each with a time-controllable pump. The pump or pumps is or are connected to a controller 20. The controller 20 is preferably a machine controller or a pulse generator. At least one feed line 21 with a connection 22 is arranged upstream of the pump or pumps.

Der Anschluss 22 ist bevorzugt mit einem Leitungssystem für einen flüssigen Schmierstoff verbindbar. An diesem Anschluss 22 ist der flüssige Schmierstoff, beispielsweise Wasser, einspeisbar. In einer weiteren Ausbildung ist der Anschluss 22 mit einem Feinfilter und/oder einem Druckregler und/oder einer Schmierstoffumlaufabsperrung gekoppelt.The connection 22 can preferably be connected to a line system for a liquid lubricant. The liquid lubricant, for example water, can be fed in at this connection 22. In a further embodiment, the connection 22 is coupled to a fine filter and / or a pressure regulator and / or a lubricant circulation shut-off.

Der flüssige Schmierstoff ist je nach dem zu verarbeitenden flüssigen Medium auszuwählen. Bevorzugt ist ein zum Schmierstoff kompatibles Fluid einsetzbar. Ist beispielsweise das zu verarbeitende Medium ein wässriger Dispersionslack, so ist bevorzugt als flüssiger Schmierstoff Wasser oder ein zum zu verarbeitenden Medium anderes verträgliches Fluid einsetzbar.The liquid lubricant should be selected depending on the liquid medium to be processed. A fluid that is compatible with the lubricant can preferably be used. For example, if the medium to be processed is an aqueous dispersion lacquer, water or a fluid which is compatible with the medium to be processed is preferably used as the liquid lubricant.

Der einsetzbare flüssige Schmierstoff dient der Reduzierung der Reibungsmomente an den Kontaktstellen von Rakelblättern 23, 24 und den Dichtungssystemen 25 mit der Auftragwalze 15 und ist gleichzeitig zum zu verarbeitenden flüssigen Medium kompatibel.The liquid lubricant that can be used serves to reduce the frictional moments at the contact points of doctor blades 23, 24 and the sealing systems 25 with the application roller 15 and is at the same time compatible with the liquid medium to be processed.

Das Verfahren und die Vorrichtung ist nicht auf das beschriebene Beispiel in einem Lackwerk 2,3 beschränkt. Vielmehr sind das Verfahren und die Vorrichtung auch in einem Offsetdruckwerk 1 einsetzbar. Hierzu ist analog zu DE 197 29 977 A1 die Dosiervorrichtung 13, gebildet aus Auftragwalze 15 und Kammerrakelsystem 16, dem Plattenzylinder 8 zugeordnet. Das Farbwerk des Offsetdruckwerkes 1 ist inaktiv und die bevorzugt gerasterte Auftragwalze 15 ist mit dem Plattenzylinder 8 in Kontakt. Je nach den Platzverhältnissen sind die Schmierstoffgeber 17 in Drehrichtung der Auftragwalze 15 vor oder nach dem Kammerrakelsystem 16, den Dichtungssystemen 25 zugeordnet, angeordnet. Das zu verarbeitende flüssige Medium wird dann von der Auftragwalze 15 an den Plattenzylinder 8 und von diesem an den Gummituchzylinder 9 übertragen.The method and device is not based on that described Example limited in a coating unit 2.3. Rather, the method and the device can also be used in an offset printing unit 1. For this purpose, analogously to DE 197 29 977 A1, the metering device 13, formed from the application roller 15 and chamber doctor blade system 16, is assigned to the plate cylinder 8. The inking unit of the offset printing unit 1 is inactive and the preferably rastered application roller 15 is in contact with the plate cylinder 8. Depending on the space available, the lubricant dispensers 17 are arranged in the direction of rotation of the application roller 15 before or after the chambered doctor blade system 16, assigned to the sealing systems 25. The liquid medium to be processed is then transferred from the application roller 15 to the plate cylinder 8 and from there to the blanket cylinder 9.

Die Wirkungsweise ist wie folgt: Im Druck-/Lackbetrieb sind die Schmierstoffgeber 17 den jeweiligen Dichtungssystemen 25 benachbart zugeordnet. Über den Anschluss 22 wird ein flüssiger Schmierstoff über die Zuführstränge 21 an die Schaltventile 19 oder Pumpen eingespeist, wobei die Schaltventile 19 oder die Pumpen mittels Steuerung 20 über die Leitungssysteme 18 den flüssigen Schmierstoff in Intervallen (intermittierend) an die Schmierstoffgeber 17 zuführen.The mode of operation is as follows: in the printing / coating operation, the lubricant dispensers 17 are assigned adjacent to the respective sealing systems 25. Via the connection 22, a liquid lubricant is fed via the feed lines 21 to the switching valves 19 or pumps, the switching valves 19 or the pumps supplying the liquid lubricant to the lubricator 17 at intervals (intermittently) by means of the control system 20 via the line systems 18.

An den Schmierstoffgebern 17 wird der flüssige Schmierstoff in Tropfenform oder als Sprühstrahl ausgetrieben und trifft auf die rotierende Auftragwalze 15, bevorzugt in Drehrichtung der Auftragwalze vor dem ersten Rakelblatt 24, auf.At the lubricant dispensers 17, the liquid lubricant is expelled in the form of drops or as a spray jet and strikes the rotating application roller 15, preferably in the direction of rotation of the application roller in front of the first doctor blade 24.

Durch die Zuführung des flüssigen Schmiermittels, vorzugsweise Wasser, wird das von der bevorzugt gerasterten Auftragwalze 15 geführte flüssige Medium, insbesondere Lack, im Bereich der Dichtungssysteme 25 geringfügig verdünnt. Dies bewirkt jedoch keine Beeinträchtigung des flüssigen Mediums bzw. der Dosier- bzw. Beschichtungsqualität. Vielmehr reduziert der flüssige Schmierstoff das Aufbauen und Aushärten des flüssigen Mediums im Bereich der Dichtungssysteme 25 sowie der Rakelblätter 23, 24.By supplying the liquid lubricant, preferably water, the liquid medium, in particular paint, guided by the preferably rastered application roller 15 is slightly diluted in the area of the sealing systems 25. However, this does not impair the liquid medium or the dosing or coating quality. Rather, the liquid lubricant the build-up and hardening of the liquid medium in the area of the sealing systems 25 and the doctor blades 23, 24.

Weiterhin wird die Funktionsfähigkeit der Kontaktstellen an den Dichtungssystemen 25 sowie den Rakelblättern 23, 24 in Verbindung mit der Auftragwalze 15 gewährleistet und der Verschleiß reduziert. Ebenso ist eine Kühlung der oben genannten Kontaktstellen erreichbar, was insbesondere bei benachbarten, aktivierten Trocknereinrichtungen 4 vorteilhaft ist.Furthermore, the functionality of the contact points on the sealing systems 25 and the doctor blades 23, 24 in connection with the application roller 15 is ensured and wear is reduced. Cooling of the abovementioned contact points can also be achieved, which is particularly advantageous in the case of adjacent, activated dryer devices 4.

Das Verfahren zum Dosieren eines flüssigen Mediums in einer Verarbeitungsmaschine enthaltend eine Auftragwalze und eine der Auftragwalze zugeordnetes Kammerrakelsystem geht davon aus, dass an den Schmierstellen, gebildet durch je ein Dichtungssystem 25 und dem Walzenmantel einer Auftragwalze 15, die Schmierstellen bevorzugt mit relativ kleinen, einstellbaren Schmierstoffmengen eines flüssigen Schmierstoffes versorgt werden.The method for dosing a liquid medium in a processing machine containing an applicator roller and a chambered doctor blade system assigned to the applicator roller assumes that at the lubrication points, formed by a sealing system 25 and the roller jacket of an applicator roller 15, the lubrication points preferably with relatively small, adjustable amounts of lubricant of a liquid lubricant.

Bevorzugt erfolgt die Versorgung mit flüssigem Schmierstoff in Drehrichtung der Auftragwalze 15 auf deren Mantelfläche vor dem Kammerrakelsystem 16 im Bereich der Dichtungssysteme 25. In einer bevorzugten Weiterbildung wird der Schmierstoff auf die Mantelfläche der Auftragwalze 15 in Intervallen (intermittierend) zugeführt. Alternativ ist der flüssige Schmierstoff in Drehrichtung der Auftragwalze 15 auf deren Mantelfläche auch nach dem Kammerrakelsystem 16 im Bereich der Dichtungssysteme 25 zuführbar.Liquid lubricant is preferably supplied in the direction of rotation of the application roller 15 on its outer surface in front of the chambered doctor blade system 16 in the area of the sealing systems 25. In a preferred development, the lubricant is supplied to the outer surface of the application roller 15 at intervals (intermittently). Alternatively, the liquid lubricant can be supplied in the direction of rotation of the application roller 15 on its outer surface, also after the doctor blade system 16 in the region of the sealing systems 25.

Alternativ ist ebenso eine kontinuierliche Schmierstoffversorgung realisierbar, wobei - bedingt durch die relativ geringe benötigte Menge an Schmierstoff - die intermittierende Schmierstoffversorgung bevorzugt wird.
Bei beiden Arbeitsverfahren (intermittierende oder kontinuierliche Zuführung) liegt das Prinzip einer Durchlaufschmierung vor, d.h. es erfolgt keine Schmierstoffrückführung.Alternatively, a continuous supply of lubricant can also be implemented, whereby - due to the relatively small amount of lubricant required - the intermittent one Lubricant supply is preferred.
The principle of continuous lubrication applies to both working methods (intermittent or continuous feeding), ie there is no return of lubricant.
