Description

Die Erfindung betrifft eine Einrichtung zum Vorfiltern des Feuchtwassers bei einer Druckmaschine mit mindestens einem Druckwerk.The invention relates to a device for prefiltering the fountain solution in a printing press with at least one printing unit.

Um das Feuchtwasser von Verunreinigungen, wie Farbpartikeln und Papierfasern, zu reinigen, ist eine Vorfiltereinrichtung vorgesehen, die jedem Druckwerk einer Druckmaschine zugeordnet ist. Diese Vorfiltereinrichtung ist in einem separaten Gehäuse angeordnet, das üblicherweise außerhalb der Druckmaschine angeordnet ist. Derartige separate Apparaturen hinterlassen nicht nur optisch einen negativen Eindruck, sondern behindern darüber hinaus auch das Arbeiten an der Druckmaschine.In order to clean the dampening water from impurities, such as ink particles and paper fibers, a pre-filter device is provided, which is assigned to each printing unit of a printing press. This pre-filter device is arranged in a separate housing, which is usually arranged outside the printing press. Such separate apparatuses not only leave a negative impression visually, but also hinder working on the printing press.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung vorzuschlagen, die diese Nachteile des Standes der Technik vermeidet.The invention has for its object to propose a device which avoids these disadvantages of the prior art.

Die Aufgabe wird dadurch gelöst, daß ein Vorfiltergehäuse vorgesehen ist, in dem ein Vorfilter angeordnet ist, und daß das Vorfiltergehäuse in das Druckwerk der Druckmaschine integriert ist.The object is achieved in that a pre-filter housing is provided, in which a pre-filter is arranged, and in that the pre-filter housing is integrated in the printing unit of the printing press.

Eine Weiterbildung der erfindungsgemäßen Einrichtung sieht vor, daß zumindest ein Teil einer Gehäusewand des Vorfiltergehäuses als Tür ausgebildet ist. Besonders vorteilhaft ist die Ausbildung, daß diese Tür gleichzeitig die Tür an der Bedienungsseite des Druckwerks ist. Durch diese Konstruktion wird erreicht, daß der Vorfilter von beispielsweise der Bedienungsseite her problemlos zugänglich ist. Ein Wechseln der Filtermatten ist leicht möglich.A further development of the device according to the invention provides that at least part of a housing wall of the prefilter housing is designed as a door. It is particularly advantageous that this door is also the door on the operating side of the printing unit. This construction ensures that the prefilter is easily accessible from the operator side, for example. It is easy to change the filter mats.

Gemäß einer Ausführungsform der erfindungsgemäßen Vorrichtung wird vorgeschlagen, daß der Rahmen des Vorfiltergehäuses mit elastischem Dichtungsmaterial versehen ist. Beispielsweise handelt es sich bei diesem Dichtungsmaterial um Schaumstoff.According to one embodiment of the device according to the invention, it is proposed that the frame of the prefilter housing be provided with elastic sealing material is provided. For example, this sealing material is foam.

Zusätzlich sind gemäß einer Weiterbildung der erfindungsgemäßen Einrichtung in dem Rahmen der Tür Stege eingeschweißt, die sich beim Schließen der Tür in das Dichtungsmaterial eindrücken. Durch diese Maßnahmen wird eine Isolation der wasserführenden Bereiche sichergestellt; Korrosion infolge von Verdampfen von Feuchtmittel oder von Verdunsten von Feuchtmittelzusätzen wird verhindert.In addition, according to a development of the device according to the invention, webs are welded into the frame of the door, which are pressed into the sealing material when the door is closed. These measures ensure insulation of the water-bearing areas; Corrosion due to the evaporation of dampening solution or the evaporation of dampening solution additives is prevented.

Gemäß einer weiteren Ausführungsform der erfindungsgemäßen Einrichtung ist vorgesehen, daß sich unter dem Filtergehäuse, in dem der Vorfilter angeordnet ist, ein Auffangbehälter für das Feuchtwasser befindet. Dieser Auffangbehälter ist so dimensioniert, daß sich bei Abstellen der Druckmaschine das Feuchtwasser hier sammelt.According to a further embodiment of the device according to the invention, it is provided that a collecting container for the dampening water is located under the filter housing in which the pre-filter is arranged. This collecting container is dimensioned so that the dampening water collects here when the printing machine is switched off.

Eine Weiterbildung der erfindungsgemäßen Einrichtung sieht Kanäle vor, in denen die Schläuche zur Rückleitung des Feuchtwassers von einem Feuchtwerk zum Vorfiltergehäuse verlaufen. Durch die Führung der Schläuche in den Kanälen behindern die Schläuche keine weiteren Stellemente des Druckwerkes. Weiterhin sind die Kanäle so konstruiert, daß bei der Schlauchführung keine kurzen Bögen oder Knicke auftreten. Da es bevorzugt an Knickstellen zu Ablagerungen kommt, läßt sich durch die glatte Schlauchführung eine Verschmutzung - und im Extremfall ein Zusetzen der Schläuche - weitgehend vermeiden.A further development of the device according to the invention provides channels in which the hoses for returning the dampening water run from a dampening unit to the prefilter housing. By guiding the hoses in the channels, the hoses do not hinder any further elements of the printing unit. Furthermore, the channels are designed in such a way that there are no short bends or kinks in the hose guide. Since deposits are preferred at kinks, the smooth hose routing largely prevents contamination - and in extreme cases clogging of the hoses.

In einer Weiterbildung der erfindungsgemäßen Einrichtung wird vorgeschlagen, daß die Oberseite des Vorfiltergehäuses als Wanne ausgebildet ist. Diese Wanne dient zum Auffangen von öl. Diese Kombination von Auffangwanne und Vorfiltergehäuse ist besonders einfach und kostengünstig.In a development of the device according to the invention it is proposed that the top of the prefilter housing is designed as a trough. This pan is used to collect oil. This combination of drip pan and prefilter housing is particularly simple and inexpensive.

Gemäß einer Weiterbildung der erfindungsgemäßen Vorrichtung ist vorgesehen, daß eine Leitung das Feuchtwasser von den Vorfiltern in den Druckwerken zu einem Hauptfilter führt. Ein derartiger Hauptfilter ist beispielsweise aus dem Gebrauchsmuster DE-U1 91 01 888 bekannt geworden.According to a development of the device according to the invention, it is provided that a line leads the fountain solution from the pre-filters in the printing units to a main filter. Such a main filter has become known, for example, from utility model DE-U1 91 01 888.

Gemäß einer weiteren Ausführungsform der erfindungsgemäßen Einrichtung ist vorgesehen, daß in dem Vorfilter eine Vorrichtung zur Anzeige des Feuchtmittelpegels angeordnet ist. Beispielsweise wird der Feuchtmittelpegel mittels eines Schwimmschalters kontrolliert. Üblicherweise ist ein Ansteigen des Feuchtmittelpegels ein Anzeichen dafür, daß der Filter infolge von Verunreinigungen zugesetzt ist und daß es im Bereich des Vorfilters zu einem Feuchtmittelstau kommt. Da überströmendes Feuchtmittel kurzzeitig auch vom Hauptfilter gereinigt werden kann, genügt es, wenn der Schwimmschalter eine Warnanzeige aktiviert. Da der Hauptfilter kurzzeitig die Aufgabe des Vorfilters übernehmen kann, kann das Austauschen der Filtermatten während des Betriebes der Druckmaschine erfolgen.According to a further embodiment of the device according to the invention it is provided that a device for displaying the dampening solution level is arranged in the prefilter. For example, the dampening solution level is checked using a float switch. An increase in the dampening solution level is usually an indication that the filter has become clogged due to impurities and that there is a dampening solution accumulation in the area of the pre-filter. Since overflowing dampening solution can also be briefly cleaned by the main filter, it is sufficient for the float switch to activate a warning indicator. Since the main filter can temporarily take over the task of the pre-filter, the filter mats can be replaced while the printing machine is in operation.

a cross section through the inventive device for pre-filtering.

In Fig. 1 ist ein Schnitt durch ein Druckwerk 1 einer nicht gesondert dargestellten Rollenrotationsdruckmaschine dargestellt. In dieses Druckwerk 1 ist die erfindungsgemäße Einrichtung zum Vorfiltern des Feuchtwassers integriert.In Fig. 1 is a section through a printing unit 1 of a web-fed rotary printing press, not shown separately shown. In this printing unit 1, the device according to the invention for pre-filtering the fountain solution is integrated.

Den Druckzylindern 17 ist ein oberes Feuchtwerk 2 bzw. ein unteres Feuchtwerk 3 zugeordnet. Der Rücklauf des Feuchtwassers von den Feuchtwerken 2, 3 erfolgt über Schläuche 4, die In Kanälen 5 geführt werden. Über die Schläuche 4 gelangt das zu reinigende Feuchtwasser in einen Vorfilter 6, in dem Filtermatten 8 angeordnet sind. Der Vorfilter 6 ist in dem Filtergehäuse 7 angeordnet. Dieses Filtergehäuse wird durch eine Tür 12 an der Bedienungsseite des Druckwerkes 1 abgeschlossen.An upper dampening unit 2 and a lower dampening unit 3 are assigned to the pressure cylinders 17. The return of the dampening water from the dampening units 2, 3 takes place via hoses 4, which are guided in channels 5. The dampening water to be cleaned passes through the hoses 4 into a pre-filter 6 in which filter mats 8 are arranged. The pre-filter 6 is arranged in the filter housing 7. This filter housing is closed by a door 12 on the operating side of the printing unit 1.

Unterhalb des Vorfilters 6 befindet sich ein Auffangbehälter 9, der zumindest so dimensioniert ist, daß er das aus den Feuchtwerken 2, 3 und dem Vorfilter 6 abfließende Feuchtwasser bei Maschinenstop aufnehmen kann. Über eine Sammelleitung 10 steht der Auffangbehälter 9 mit dem Hauptfilter 19 in Verbindung.Below the pre-filter 6 there is a collecting container 9 which is at least dimensioned such that it can hold the dampening water flowing out of the dampening units 2, 3 and the pre-filter 6 when the machine stops. The collecting container 9 is connected to the main filter 19 via a collecting line 10.

In dem Vorfilter 6 ist ein Pegelanzeiger 20, beispielsweise ein Schwimmschalter, angeordnet, der bei überschreiten eines gewissen Pegelstandes eine Warnanzeige aktiviert.A level indicator 20, for example a float switch, is arranged in the pre-filter 6 and activates a warning display when a certain level is exceeded.

Fig. 2 zeigt einen Längsschnitt durch die erfindungsgemäße Einrichtung zum Vorfiltern des Feuchtwasser. Die erfindungsgemäße Vorrichtung ist im unteren Bereich des Druckwerkes 1 angeordnet. Das Feuchtwasser wird von dem oberen bzw. unteren Feuchtwerk 2, 3 über Schläuche 4 in den Vorfilter 6 geleitet. Diese Schläuche 4 sind in Kanälen 5 geführt.Fig. 2 shows a longitudinal section through the device according to the invention for pre-filtering the fountain solution. The device according to the invention is arranged in the lower region of the printing unit 1. The dampening water is fed from the upper and lower dampening units 2, 3 into the prefilter 6 via hoses 4. These hoses 4 are guided in channels 5.

Der Vorfilter 6, in dem die Filtermatten 8 angeordnet sind, befindet sich in dem Filtergehäuse 7. Unterhalb des Vorfilters 6 befindet sich der Auffangbehälter 9. Von diesem Auffangbehälter 9 wird das Feuchtmittel über eine Leitung 10 zum nicht dargestellten Hauptfilter 19 geleitet.The prefilter 6, in which the filter mats 8 are arranged, is located in the filter housing 7. Below the prefilter 6, there is the collecting container 9. From this collecting container 9, the dampening solution is transferred via a Line 10 passed to the main filter 19, not shown.

Das Vorfiltergehäuse 7 wird durch eine Tür 12 abgeschlossen. Diese Tür 12 ist gleichzeitig die Tür an der Bedienungsseite des Druckwerkes 1. Der Rahmen des Vorfiltergehäuses 7, der zur Aufnahme der Tür 12 dient, ist mit elastischem Dichtungsmaterial 13 versehen. Bei diesem elastischen Dichtungsmaterial 13 handelt es sich beispielsweise um Schaumstoff. Um einen Abschluß der feuchtmittelführenden Bereiche zu erzielen, sind zusätzlich am Rahmen der Tür Stege vorgesehen, die sich beim Schließen der Tür in das Dichtungsmaterial eindrücken. Hierdurch wird eine wirkungsvolle Abdichtung der feuchtmittelführenden Bereiche erzielt. Durch öffnen der Tür 12 von der Bedienerseite her wird der Vorfilter 6 problemlos zugänglich, was beispielsweise das Wechseln der Filtermatten 8 wesentlich erleichtert.The prefilter housing 7 is closed by a door 12. This door 12 is also the door on the operating side of the printing unit 1. The frame of the pre-filter housing 7, which serves to accommodate the door 12, is provided with elastic sealing material 13. This elastic sealing material 13 is, for example, foam. In order to achieve a seal of the dampening agent-carrying areas, webs are additionally provided on the frame of the door, which are pressed into the sealing material when the door is closed. This results in an effective sealing of the areas that carry the dampening solution. By opening the door 12 from the operator side, the prefilter 6 is easily accessible, which, for example, makes changing the filter mats 8 considerably easier.

Vorteilhafterweise ist die Oberseite 15 des Vorfiltergehäuses 7 als Wanne 18 ausgebildet. Damit ist die Oberseite 15 des Vorfiltergehäuses 7 gleichzeitig dazu geeignet, aus Lagerungen austretendes öl der Zentralschmierung aufzufangen. Da die Oberseite 15 des Vorfiltergehäuses 7 somit eine Doppelfunktion erfüllt, ist diese Ausbildung besonders kostengünstig. Über einen Ablaufstutzen 16 wird das öl von der Wanne 17 abgeführt.The top 15 of the prefilter housing 7 is advantageously designed as a trough 18. Thus, the top 15 of the prefilter housing 7 is at the same time suitable for collecting oil from central lubrication escaping from bearings. Since the upper side 15 of the prefilter housing 7 thus fulfills a double function, this design is particularly cost-effective. The oil is discharged from the trough 17 via an outlet connection 16.

Fig. 3 zeigt einen Querschnitt durch die erfindungsgemäße Vorrichtung zum Vorfiltern des Feuchtwassers. Im oberen Bereich des Filtergehäuses 7 ist der Vorfilter 6 angeordnet; im unteren Bereich befindet sich der Auffangbehälter 9. Über Dichtungsmaterial 13 und in dieses Dichtungsmaterial eingreifende Stege 14, die sich an der Innenseite der Tür 12 befinden, wird eine Abschottung der feuchtmittelführenden Bereiche erzielt.Fig. 3 shows a cross section through the device according to the invention for prefiltering the fountain solution. The prefilter 6 is arranged in the upper region of the filter housing 7; The collecting container 9 is located in the lower area. Sealing material 13 and webs 14 engaging in this sealing material, which are located on the inside of the door 12, isolate the areas that carry the dampening solution.

Die feuchtmittelführenden Schläuche 4 sind durch die Seitenwand 11 des Druckwerkes 1 und danach durch Kanäle 5 geführt, so daß sie keine Stellelemente des Druckwerkes 1 behindern.The dampening agent-carrying hoses 4 are guided through the side wall 11 of the printing unit 1 and then through channels 5, so that they do not impede any control elements of the printing unit 1.

Bei der Konstruktion der Kanäle 5 ist darauf geachtet worden, daß die Schlauchführung möglichst ohne kurze Bögen und Knicke erfolgt, wodurch einer Verschmutzung - und eventuell einer Verstopfung der Schläuche - vorgebeugt wird.In the construction of the channels 5, care has been taken to ensure that the hose is routed without short bends and kinks, which prevents contamination - and possibly blockage of the hoses -.
