Description

Die Erfindung betrifft eine Lackiervorrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a painting device according to the preamble of patent claim 1.

Eine derartige Lackiervorrichtung ist aus der DE-A-33 24 096 bekannt. Es handelt sich hierbei um eine stationär an einer Druckmaschine angeordnete Lackiervorrichtung (auch als "Lackierwerk" bezeichnet), bei der die dort vorgesehenen drei Walzen ausgebildet sind als Schöpfwalze, die das aufzutragende Medium einem Vorratsbehälter entnimmt, als Dosierwalze, die die Menge dieses Mediums dosiert, und als Auftragswalze, die das Medium auf den Druckzylinder überträgt.Such a painting device is known from DE-A-33 24 096. It is a coating device (also referred to as a "coating unit") arranged in a stationary position on a printing press, in which the three rollers provided there are designed as a scoop roller, which takes the medium to be applied from a storage container, as a metering roller, which doses the amount of this medium , and as an application roller that transfers the medium to the printing cylinder.

Bei dieser Lackiervorrichtung werden die Walzen in Arbeitsposition, also beim Auftragen des Mediums, vom Antrieb der Druckmaschine beaufschlagt, also mit diesem zwangsgekoppelt; in der Ruheposition ist das Lackierwerk vom Druckzylinder entkoppelt, gegebenenfalls kann über einen separaten Antrieb eine Rotation der Walzen sichergestellt werden, um das Antrocknen des Mediums zu verhindern.In this coating device, the rollers in the working position, that is to say when the medium is being applied, are acted upon by the drive of the printing press, that is to say they are positively coupled to it; In the rest position, the coating unit is decoupled from the printing cylinder; if necessary, the rollers can be rotated via a separate drive to prevent the medium from drying.

Zur Gewährleistung eines feinen, qualitativ hochwertigen Lackauftrages auf den Druckzylinder (auf das zu beschichtende Gut), bedarf es feinfühliger Einstellmöglichkeiten, um eine möglichst genau dosierbare Menge des Mediums möglichst gleichmäßig auf dem zu beschichtenden Gut auf dem Druckzylinder zu verteilen. Hierüber sind in der vorgenannten Druckschrift keine Angaben gemacht.To ensure a fine, high-quality coating application on the printing cylinder (on the material to be coated), sensitive adjustment options are required in order to distribute an amount of the medium that can be dosed as precisely as possible on the material to be coated on the printing cylinder. About this no information is given in the aforementioned publication.

Die stationäre Zuordnung einer solchen Lackiervorrichtung an dem Druckzylinder einer Druckmaschine ist darüber hinaus apparativ aufwendig und wird auch nur gelegentlich benötigt, so daß der Nutzen der entsprechenden Investition nicht optimal ist.The stationary assignment of such a coating device to the printing cylinder of a printing press is also expensive in terms of equipment and is only occasionally required, so that the benefit of the corresponding investment is not optimal.

Aufgabe der Erfindung ist es daher, eine solche Lackiervorrichtung derart auszubilden, daß ein rationellerer Einsatz gewährleistet ist und insbesondere dabei zuverlässige Einstellmöglichkeiten des Anpreßdruckes der Auftragwalze an den Druckzylinder erreicht werden.The object of the invention is therefore to design such a coating device in such a way that more rational use is ensured and in particular reliable setting options for the contact pressure of the application roller on the printing cylinder are achieved.

Erfindungsgemäß wird diese Aufgabe durch den kennzeichnenden Teil des Patentanspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing part of patent claim 1.

Aus dieser Lösung ergeben sich folgende Vorteile:The advantages of this solution are as follows:

Als Baueinheit ist die Lackiervorrichtung einfach an eine vorhandene Druckmaschine, also in definiertem Abstand zum Druckzylinder anbringbar, was nur wenige Minuten Montage erfordert. Bei Dispersionslack bis 4 g pro m² Auftragsdicke sind hierbei keinerlei zusätzliche Trocknungsanlagen erforderlich, erst danach muß eine IR-Trocknungsanlage nachgeschaltet werden. Es können ansonsten Dispersions- und UV-Lacke verwendet werden, bei letzteren ist mit entsprechender UV-Trocknung zu arbeiten. Da keine Auftragsdüsen verwendet werden, ist ein gleichmäßiger Lackauftrag und eine konstante Lackmengenzufuhr bei einfachster Einstellung gesichert.As a structural unit, the coating device can simply be attached to an existing printing press, that is to say at a defined distance from the printing cylinder, which requires only a few minutes of assembly. In the case of dispersion varnish up to 4 g per m² application thickness, no additional drying systems are required, only then an IR drying system must be connected. Otherwise, dispersion and UV varnishes can be used, with the latter you have to work with appropriate UV drying. Since no application nozzles are used, an even application of varnish and a constant amount of varnish is ensured with the simplest setting.

Der Bedienungsaufwand ist daher auf ein Minimum reduziert, die Vorrichtung arbeitet weitgehend wartungsfrei und bei der Druckmaschine selbst sind keinerlei Änderungen erforderlich; insbesondere bleiben alle Sicherheitsvorrichtungen komplett erhalten, auch die volle Druckleistung der vorgeschalteten Druckmaschine wird nicht beeinträchtigt.The operating effort is therefore reduced to a minimum, the device works largely maintenance-free and no changes are necessary in the printing press itself; in particular, all safety devices are completely preserved, and the full printing performance of the upstream printing machine is not impaired.

Die erfindungsgemäße Konzeption zur Steuerung des Anpreßdruckes der Auftragswalze an den Druckzylinder schafft somit die Möglichkeit eines zuverlässigen Betriebes, auch bei der gewünschten Ausführung der Lackiervorrichtung als separate Baueinheit, wo es infolge der nicht-stationären Zuordnung von Lackiervorrichtung zu Druckzylinder besonders auf die feinfühlige Steuerung dieses Anpreßdruckes zur Erzielung von qualitativ hochwertigen Druckergebnissen ankommt.The concept according to the invention for controlling the contact pressure of the application roller on the printing cylinder thus creates the possibility of reliable operation, even with the desired execution of the coating device as a separate structural unit, where, due to the non-stationary assignment of the coating device to the printing cylinder, it is particularly important for the sensitive control of this contact pressure arrives to achieve high quality printing results.

Eine vorteilhafte Ausgestaltung der erfindungsgemäßen Lackiervorrichtung wird anhand der Zeichnung näher erläutert:An advantageous embodiment of the painting device according to the invention is explained in more detail with reference to the drawing:

Die Lackiervorrichtung besteht aus einem Gehäuse aus Aluminium, in dem drei walzen mit zueinander parallelen Achsen so gelagert sind, daß sie miteinander linienförmigen Kontakt haben können, nämlich eine Auftragwalze 10, eine Dosierwalze 11 und eine Schöpfwalze 12.The painting device consists of a housing made of aluminum, in which three rollers with axially parallel axes are mounted so that they can have linear contact with one another, namely an application roller 10, a metering roller 11 and a scoop roller 12.

Die Auftragwalze 10 ist mit der Dosierwalze 11 in einem gemeinsamen, schlittenartigen Walzenstuhl 20 gelagert, der seinerseits im Gehäuse gehalten ist. Der Walzenstuhl 20 wird über eine Exzenterwelle 21 von einem ersten Hilfsmotor 21A beaufschlagt, derart, daß die Bewegung der Exzenterwelle 21 zu einer Verschiebung des Walzenstuhls 20 relativ zum Eindruckzylinder 40 der Druckmaschine führt. Über eine Rändelschraube 21B kann dabei die Exzentrizität der Exzenterwelle und damit der Walzenstuhlhub verändert werden, womit eine leichte Einstellung des Anpreßdruckes der Auftragwalze 10 an den Druckzylinder 40 möglich ist.The application roller 10 is mounted with the metering roller 11 in a common, sled-like roller mill 20, which in turn is held in the housing. The roller mill 20 is acted upon by a first auxiliary motor 21A via an eccentric shaft 21, such that the movement of the eccentric shaft 21 leads to a displacement of the roller mill 20 relative to the impression cylinder 40 of the printing press. The eccentricity of the eccentric shaft and thus the roller mill stroke can be changed by means of a knurled screw 21B, whereby an easy adjustment of the contact pressure of the application roller 10 against the pressure cylinder 40 is possible.

Die Dosierwalze 11 kann in ihrer Relativposition zur Auftragwalze 10 ebenfalls durch ein Rändelrad 21C beeinflußt werden und damit die Lackmenge bestimmt werden.The metering roller 11 can also be influenced in its position relative to the applicator roller 10 by a knurled wheel 21C and thus the amount of paint can be determined.

Die Verbindung zwischen der Dosierwalze 11 und der Lackwanne 13 am Boden des Lackierwerksgehäuses stellt die Schöpfwalze 12 her, die an einem Exzenterhebel 14 gehalten ist, über den die Lack-Wulstmenge eingestellt werden kann, also die Menge des sich oberhalb des Spaltes zwischen Auftragwalze 10 und Dosierwalze 11 bildenden Lackreservoirs, eingestellt werden kann.The connection between the metering roller 11 and the coating pan 13 at the bottom of the coating unit housing is produced by the scoop roller 12, which is held on an eccentric lever 14 by means of which the amount of coating bead can be adjusted, i.e. the amount of the gap between the application roller 10 and Metering roller 11 forming paint reservoirs can be adjusted.

Die beschriebenen Einstellmöglichkeiten ergeben einen feinen dosierbaren Lackauftrag auf den Druckzylinder 40.The setting options described result in a fine, meterable coating of paint on the printing cylinder 40.

Zum Antrieb der Walzen 10-12 sind Möglichkeiten vorgesehen, die im praktischen Betrieb (wie weiter unten näher erläutert) sich ergänzen:Options are provided for driving the rollers 10-12, which complement one another in practical operation (as explained in more detail below):

Die Auftragwalze 10 ist über einen Freilauf mit einem Zahnrad verbunden, das mit dem gestrichelt dargestellten Zahnrad kämmt, das seinerseits vom Antrieb der Druckmaschine angetrieben wird. Solange die Druckmaschine läuft und der Druckzylinder 40 rotiert, wird über diese starre Zahnradkoppelung also auch die Walzenkombination des Lackierwerkes bewegt.The application roller 10 is connected via a freewheel to a gear which meshes with the gear shown in dashed lines, which in turn is driven by the drive of the printing press. As long as the printing press is running and the printing cylinder 40 is rotating, the roller combination of the coating unit is also moved via this rigid gear coupling.

Die Dosierwalze 11 ist mit einem nicht dargestellten zweiten Hilfsmotor verbunden, der ebenfalls über einen Freilauf mit der Dosierwalze in Verbindung steht, so daß die Dosierwalze und über die anderen (nicht dargestellten) die Walzen verbindenden Zahnräder die Walzenanordnung in Betrieb gehalten werden kann, auch wenn der Antrieb der Druckmaschine steht. Dadurch kann erreich werden, daß auch bei Arbeitsunterbrechungen das Antrocknen des Lackes an den Walzen und den diesen zugeordneten Rakeln verhindert wird.The metering roller 11 is connected to a second auxiliary motor, not shown, which is also connected to the metering roller via a freewheel, so that the metering roller and the other gear wheels (not shown) connecting the rollers can keep the roller arrangement in operation, even if the drive of the printing machine is stopped. It can thereby be achieved that the drying of the lacquer on the rollers and the doctor blades associated therewith is prevented even when work is interrupted.

Die Lackwanne 13, in die die Schöpfwalze 12 eintaucht, ist mit einer Sicherheitswanne 13A verbunden, in die von oben ein Schlauch 13B eintaucht, der die Verbindung zu einem oberhalb des Lackniveaus angeordneten Lackvorratsbehälter 13C herstellt. Der Lackvorratsbehälter 13C ist luftdicht abgeschlossen, so daß der Zulauf von Lack in die Sicherheitswanne 13A und somit in die Lackwanne 13 nur erfolgen kann, wenn das Niveau des Lackes in der Lackwanne 13 unterhalb der Austrittsöffnung des in die Sicherheitswanne 13A ragenden Schlauchendes liegt, da nur dann Außenluft durch den Schlauch 13B in den Lackvorratsbehälter 13C gelangen kann.The paint trough 13, into which the scoop roller 12 is immersed, is connected to a safety trough 13A, into which a hose 13B is immersed from above, which connects to a paint storage container 13C arranged above the paint level. The paint reservoir 13C is hermetically sealed, so that the supply of paint into the safety trough 13A and thus into the paint trough 13 can only take place if the level of the paint in the paint trough 13 is below the outlet opening of the hose end projecting into the safety trough 13A, since only then outside air can pass through the hose 13B into the paint reservoir 13C.

Die Arbeitsweise der Lackiervorrichtung wird nun im folgenden beschrieben:The operation of the painting device is now described in the following:

Bei laufender Druckmaschine werden die Walzen von dem gestrichelt dargestellten Zahnrad des Druckmaschinenantriebs mitgenommen, wobei durch eine geeignete Einstellung der Exzenterwelle dafür gesorgt ist, daß der Walzenstuhl 20 sich in dem einen Totpunkt seines Hubes befindet, in dem die Auftragwalze 10 mit dem durch die Exzentrizität der Exzenterwelle vorgebbaren Anpreßdruck auf den Druckzylinder 40 wirkt. In an sich bekannter Weise wird dann von der Schöpfwalze 12 von der Lackwanne 13 über die Dosierwalze 11 eine bestimmte Menge Lack zur Auftragwalze gefördert, die dann auf auf dem Druckzylinder befindliche zu beschichtende Druckerzeugnis aufgetragen wird. Soll dieser Beschichtungsvorgang unterbrochen werden, so erhält der erste Hilfsmotor 21A ein entsprechendes Steuersignal, worauf er über die Exzenterwelle 21 den Walzenstuhl 20 in dessen anderen Totpunkt bewegt, in dem die Auftragwalze 10 keinen Funktionskontakt mehr mit dem Druckzylinder 40 hat, also keine Beschichtung stattfindet. Der Hub des Walzenstuhls 20 ist jedoch in aller Regel zu gering, so daß die Zahnradkoppelung zwischen dem Druckmaschinenantrieb und der Auftragwalze bestehen bleibt, daß die Lackiervorrichtung also in Bewegung bleibt.When the printing press is running, the rollers are taken along by the gearwheel of the printing press drive, which is shown in dashed lines, whereby a suitable setting of the eccentric shaft ensures that the roller mill 20 is in the one dead center of its stroke, in which the application roller 10 with the the eccentricity of the eccentric shaft predetermined pressure acts on the pressure cylinder 40. In a manner known per se, the scoop roller 12 then conveys from the coating pan 13 via the metering roller 11 a certain amount of coating material to the application roller, which is then applied to the printed product to be coated on the printing cylinder. If this coating process is to be interrupted, the first auxiliary motor 21A receives a corresponding control signal, whereupon it moves the roller mill 20 via the eccentric shaft 21 to its other dead center, in which the application roller 10 no longer has a functional contact with the printing cylinder 40, that is to say no coating takes place. However, the stroke of the roller mill 20 is generally too small, so that the gear coupling between the printing press drive and the application roller remains, so that the coating device remains in motion.

Der Lackauftrag auf den Druckzylinder 40 kann also während des Betriebs der Druckmaschine einfach durch Betätigung des Hilfsmotors 21A gesteuert werden.The coating application to the printing cylinder 40 can thus be controlled simply by operating the auxiliary motor 21A during the operation of the printing press.

Beim Stillstand der Druckmaschine wird natürlich auch die Lackiervorrichtung nicht mehr über die gekoppelten Zahnräder vom Antrieb der Druckmaschine in Bewegung versetzt, in diesem Falle wird so verfahren, daß zunächst der Hilfsmotor 21A den Walzenstuhl 20 wieder in seinen hinteren Totpunkt verfährt, so daß der Kontakt zwischen Auftragwalze und Druckzylinder aufgehoben wird, und daß sich dann der zweite Hilfsmotor zuschaltet, der die Dosierwalze 11 und damit über die (nicht dargestellten) Zahnradverbindungen die gesamte Walzenanordnung antreibt, was infolge des Freilaufs zwischen den beiden Zahnrädern der Auftragwalze 10 und dem Druckmaschinenantrieb möglich ist. Die Drehzahl des zweiten Hilfsmotors ist dabei so bestimmt, daß die Lackiervorrichtung sozusagen im "Leerlauf" genügend Lack aus der Lackwanne 13 fördert, um einen ständigen Lackaustausch auf den Walzenoberflächen zu bewirken, der das Antrocknen des Lackes verhindert.When the printing machine is at a standstill, the painting device is of course no longer set in motion by the drive of the printing machine via the coupled gearwheels, in this case the procedure is such that first the auxiliary motor 21A moves the roller mill 20 back to its dead center, so that the contact between Application roller and impression cylinder is lifted, and that then the second auxiliary motor switches on, which drives the metering roller 11 and thus via the gear connections (not shown) the entire roller arrangement, which is possible as a result of the freewheeling between the two gears of the application roller 10 and the printing press drive. The speed of the second auxiliary motor is determined so that the painting device promotes enough paint, so to speak, in "idle" from the paint tub 13 to cause a constant paint exchange on the roller surfaces, which prevents the paint from drying.
