Description
Die Erfindung betrifft eine Druckmaschine zum Bedrucken von Bogen, insbesondere mit einem Farbwerk, sowie mit Druckwerkszylindern in Form eines Plattenzylinders, eines Gummituchzylinders und eines Druckzylinders, mit einer einen Vorratsbehälter und eine betriebsmäßig mit dessen Inhalt versorgbare Sprühdüse umfassenden Sprühvorrichtung zum Austrag von Abstandstoffpartikeln, die zur Ausbildung eines gegenseitigen Abstandes zwischen Bogen in einem gestapelten Zustand derselben vorgesehen sind, wobei der Austrag auf einen der Druckwerkszylinder oder auf die Bogen erfolgt.The invention relates to a printing machine for printing sheets, in particular with an inking unit, as well as with printing unit cylinders in the form a plate cylinder, a blanket cylinder and an impression cylinder, with one a storage container and one operationally with its contents supplyable spray nozzle comprising spray device for the discharge of Spacer particles that form a mutual distance are provided between sheets in a stacked state thereof, the discharge on one of the printing unit cylinders or on the sheets he follows.
Eine derartige Druckmaschine ist beispielsweise aus der Druckschrift
DE 43 41 566 A1 bekannt. Bei der hierin offenbarten Sprühvorrichtung ist der
Vorratsbehälter derselben mit den Abstandstoffpartikeln befüllt. Diese werden
betriebsmäßig über eine Düse auf eine entweder an einem Bogen oder an
einem Druckwerkszylinder vorgesehene Zielfläche ausgeblasen, wo die
Abstandstoffpartikel sodann eine Trennmittelschicht ausbilden.Such a printing press is, for example, from the
Bei einer der offenbarten Varianten ist zusätzlich zu einer die Abstandstoffpartikel auf eine Zielfläche blasenden Düse eine weitere Düse vorgesehen, die ein und dieselbe Zielfläche mit einem Befeuchtungsmittel besprüht. Dabei ist hinsichtlich der Abstandstoffpartikel und des Befeuchtungsmittels eine derartige Stoffauswahl getroffen, daß sich die auf die Zielfläche aufgetragene Trennmittelschicht biologisch abbaut.In one of the variants disclosed, in addition to one Spacer particles on a target blowing nozzle another nozzle provided the same target area with a humidifier sprayed. It is with regard to the spacer particles and Humidifier made such a selection of materials that the Biologically degrades the release agent layer applied to the target surface.
Letzteres ist zwar für die vorliegende Erfindung nicht von Bedeutung, doch durch den Austrag eines Befeuchtungsmittels auf die mit den Abstandstoffpartikeln besprühte Zielfläche ergibt sich als wünschenswerte Nebenwirkung eine Reduzierung der Anzahl von vagabundierenden Abstandstoffpartikeln.The latter is not important for the present invention, but it is by dispensing a humidifier on the with the Target area sprayed with spacer particles is found to be desirable Side effect is a reduction in the number of strolling Spacer particles.
Aus der Druckschrift JP Hei 5-85074 A ist es bekannt, einen bedruckten Bogen mit einer wässrigen Emulsion aus Wachs und einem Alkohol-Fettsäuren-Ester zu überziehen. Diese Emulsion wird gleichmäßig und flächig auf die gesamte Oberfläche des zuvor bedruckten Bogens aufgebracht. Nachteilig dabei ist, daß insbesondere bei großformatigen Druckbogen erhebliche Mengen der genannten Emulsion benötigt werden und daß sich beim Stapeln solcher flächig bestrichenen Druckbogen keine Luftpolster zwischen den einzelnen Bogen ausbilden können. Dies erschwert insbesondere eine kantengenaue Stapelbildung.From JP Hei 5-85074 A it is known to have a printed sheet with an aqueous emulsion of wax and an alcohol-fatty acid ester to cover. This emulsion becomes even and flat on the whole Surface of the previously printed sheet applied. The disadvantage here is that especially in the case of large-format printed sheets, considerable amounts of mentioned emulsion are needed and that when stacking such flat printed sheets no air cushions between the individual Can form arches. This complicates in particular an edge-precise Stacking.
Der Erfindung liegt die Aufgabe zugrunde, die eingangs genannte Druckmaschine so auszugestalten, daß beim Austrag von Abstandstoffpartikeln mittels einer Sprühvorrichtung eine Staubbildung vermieden wird.The invention has for its object the aforementioned To design printing press so that when removing spacer particles dust formation is avoided by means of a spray device.
Zur Lösung dieser Aufgabe ist die genannte Druckmaschine ausgestattet mit einem Vorratsbehälter, dessen Inhalt eine Sprühflüssigkeit in Form einer die Abstandstoffpartikel enthaltenden wäßrigen Suspension darstellt, die der Sprühdüse mittels einer Pumpe zuführbar ist, mit zwei zueinander parallel angeordneten, einen Spalt bildenden Walzen, mittels welcher ein aus der Sprühdüse austretender Sprühkegel begrenzbar ist und mit einer den beiden Walzen zugeordneten Reinigungsvorrichtung, mittels welcher an den Walzen haftende Reste der Suspension von den Walzen entfernbar und in den Vorratsbehälter zurückführbar sind. Diese Lösung hat überdies gegenüber dem aus der genannten Druckschrift JP Hei 5-85074 A bekannten Verfahren den Vorteil einer punktuellen Verteilung von Abstandstoffpartikeln auf den Bogen, so daß sich bei deren Stapelung Luftpolster zwischen den Bogen ausbilden können.To solve this problem, the printing press is equipped with a storage container, the content of which is a spray liquid in the form of a Aqueous suspension containing spacer particles, which the Spray nozzle can be fed by means of a pump, with two parallel to each other arranged, forming a gap, by means of which one of the Spray nozzle emerging spray cone can be limited and with one of the two Cleaning device associated with rollers, by means of which on the rollers adhering residues of the suspension removable from the rollers and in the Storage containers are recyclable. This solution also has over the known from the document JP Hei 5-85074 A known the Advantage of a selective distribution of spacer particles on the sheet, so that when they are stacked, air cushions form between the sheets can.
Des weiteren ist bevorzugt, vorgesehen, daß die Sprühdüse schwenkbar ist, wobei durch Schwenken der Sprühdüse das Auftragen der Sprühflüssigkeit unterbrochen werden kann.Furthermore, it is preferred to provide that the spray nozzle is pivotable, by applying the spray liquid by swiveling the spray nozzle can be interrupted.
In weiterer Ausgestaltung ist vorgesehen, daß die Walzen zueinander parallel verschiebbar angeordnet sind, um den zwischen ihnen liegenden Spalt schließen zu können und somit das Auftragen der Sprühflüssigkeit zu unterbrechen.In a further embodiment it is provided that the rollers are parallel to one another are slidably arranged around the gap between them to be able to close and thus the application of the spray liquid interrupt.
Die Erfindung ist nachfolgend unter Bezugnahme auf die beigefügten Zeichnungen näher erläutert.The invention is hereinafter with reference to the accompanying Drawings explained in more detail.

Eine nach dem in Fig. 1 wiedergegebenen Funktionsprinzip arbeitende
Sprühvorrichtung 40 bzw. 40' findet Verwendung in einer Druckmaschine zum
Bedrucken von Bogen, die insbesondere gemäß den Figuren 3a und 3b
ausgebildet ist, welche schematisch jeweils jenen Teil der Druckmaschine
wiedergeben, in welchem sich an ein Druckwerk 25 ein Ausleger 21 anschließt.
Das Druckwerk 25 umfaßt einen Druckzylinder 12, einen Gummituchzylinder 15
und einen Plattenzylinder 16, um den ein Farbwerk 18 und im Falle eines
Betriebes der Druckmaschine im Naß-Offsetverfahren ein Feuchtwerk 17
gruppiert sind. Ein jeweiliger Bogen 1 wird dem Druckzylinder 12 mittels eines
Bogenführungszylinders 19 zugeführt.A working according to the functional principle shown in Fig. 1
Für die Anordnung der Sprühvorrichtung 40 bzw. 40' in der Druckmaschine
besteht eine Reihe von Möglichkeiten. Hiervon sind zwei in den Figuren 3a und
3b gezeigt. In Fig. 3a ist eine Anordnung vorgesehen, bei welcher die
ausgetragene Sprühflüssigkeit unmittelbar auf die frisch bedruckte Seite des
jeweiligen Bogens auftrifft. Bei einer Anordnung gemäß Fig. 3b ist eine
Sprühvorrichtung 40' nach dem Funktionsprinzip der Sprühvorrichtung 40
gemäß Fig. 1 so angeordnet, daß die ausgetragene Sprühflüssigkeit auf einen
Bereich des Druckzylinders 12 auftrifft, auf den sich im Verlauf der Drehung
desselben an diesen seitens des Bogenführungszylinders 19 übergebene
Bogen 1 auflegen. Hierbei erfolgt ein Auftrag der Sprühflüssigkeit auf die
Bogen 1 indirekt über den Druckzylinder 12 auf die der frisch bedruckten Seite
gegenüberliegende Seite der Bogen 1.For the arrangement of the
Wie in Fig. 1 schematisch dargestellt, umfaßt die Sprühvorrichtung 40 im
einzelnen Düsen 41, denen einerseits Druckluft über eine entsprechende
Druckluftleitung 48 und andererseits die Sprühflüssigkeit über eine
Sprühstoffleitung 49 zugeführt werden. Die Sprühflüssigkeit ist eine wässrige
Suspension, die Abstandstoffpartikel und in weiterer Ausgestaltung einen in
Wasser gelösten Klebstoff enthält, wobei die Abstandstoffpartikel des weiteren
bevorzugt mittels eines Wachses gebildet sind. Die über die
Sprühstoffleitung 49 zugeführte Sprühflüssigkeit wird aus einem
Vorratsbehälter 46 mittels einer Pumpe 47 abgesaugt. Zur Begrenzung eines
an einer jeweiligen Düse 41 entstehenden Sprühkegels ist eine bevorzugt aus
zwei Walzen 42 und 43 gebildete Begrenzungsvorrichtung vorgesehen. Die
Anordnung der beiden Walzen 42 und 43 erfolgt derart, daß sich ein Spalt
zwischen ihnen ausbildet, durch den ein Teil des Sprühkegels hindurchtreten
kann. Um zu verhindern, daß an den Mantelflächen der Walzen 42 und 43
abgelagerte Reste der Sprühflüssigkeit den Spalt verstopfen, werden die
beiden Walzen 42 und 43 gedreht und abgerakelt. Dabei wird die Drehrichtung
so gewählt, daß sich die beiden Mantelflächen im Bereich des Spalts
entgegengesetzt zur Sprührichtung drehen.As shown schematically in Fig. 1, the
Eine Reinigungsvorrichtung für die Walzen 42 und 43, die in der in Figur 1
gezeigten Anordnung aus Rakeln 44 und 45 besteht, reinigt die Walzen 42 und
43 von anhaftenden Resten der Sprühflüssigkeit und führt diese in den
Vorratsbehälter 46 zurück.A cleaning device for the
Die den Spalt zwischen den beiden Walzen 42 und 43 passierende Menge der
Sprühflüssigkeit kann neben der Einstellung von Sprühparametern, wie
Druckluftmenge oder Menge der den Sprühdüsen zugeführten Sprühflüssigkeit,
durch die Breite des genannten Spalts gesteuert werden. Hierzu sind die
Walzen 42 und 43 zueinander verstellbar angeordnet. Neben einer parallelen
Verschiebung der beiden Walzen 42 und 43 zueinander, die eine konstante
Breite des Spalts über die gesamte Länge der Walzen 42 und 43 ergibt, ist
auch denkbar, durch eine entsprechende Verschiebung einer der Walzen 42
und 43 eine unterschiedliche Breite des Spaltes über die Druckmaschinenbreite
einzustellen. Zur Abschaltung beziehungsweise Unterbrechung des
Sprühkegels gibt es außer der Abschaltung der Pumpe 47 beziehungsweise
der Druckluft 48 die in Figur 2a gezeigte Möglichkeit, die Sprühdüsen so zu
schwenken, daß von diesen abgegebene Sprühkegel nicht auf den Spalt
treffen. Hierbei wird jedoch zweckmäßigerweise sichergestellt, daß die
Sprühflüssigkeit in den Vorratsbehälter 46 gelangt. Im vorliegenden Beispiel
wird dies dadurch erreicht, daß sich die Sprühdüsen 41 innerhalb des
Vorratsbehälters 46 befinden und nach dem Schwenken beispielsweise auf
eine Seitenwand desselben gerichtet sind. Eine weitere Möglichkeit besteht
darin, den von den beiden Walzen 42 und 43 gebildeten Spalt zu schließen,
indem diese aufeinander zu bewegt werden, wie dies schematisch in Figur 2b
gezeigt ist.The amount of the passing through the gap between the two
Durch entsprechendes Unterbrechen des Sprühkegels ist insbesondere
erreichbar, daß beispielsweise ein Besprühen von Greifereinrichtungen
verhindert wird, mittels welcher die Bogen 1 transportiert werden.By appropriately interrupting the spray cone is particularly
achievable that, for example, spraying gripper devices
is prevented by means of which the
