Definitions
- the invention relates to a filter device for the fountain solution circulation of an offset printing press.
- Dampening agents are used in offset printing to moisten those parts of the surfaces of the printing plates where inking is to be prevented.
- Moisturizers usually consist of water with a number of additives for adjusting the surface tension, the PH value, the corrosion behavior, etc. An important component is usually alcohol. Other additives are used to determine the pH value for controlling algae, fungi, bacteria, preventing corrosion, etc.
- Fountain solutions of this type usually pass through a circuit with a dampening solution container, a supply line, a system for moistening the printing cylinder of the machine, a return for excess dampening solution and at least one filter device in the return region (such as in US-A-5,622,620 ).
- the dampening solution is more or less freed of impurities, in particular of air dust, paper dust and ink particles. Because a thorough filtration of the dampening solution offers the opportunity to use it repeatedly in the circulation and thus to reduce the costs for the production of new dampening solution and the disposal of the spent dampening solution, partially multi-stage filter systems are used.
- a known filter system shows and describes the DE 199 55 624 A1 ,
- the EP 0 180 541 A1 describes a method and a system for cleaning a printing form, wherein a printing forme is cleaned with a high-pressure water jet.
- the refluxing water is filtered in a filter unit, flows to a container and is sucked up again in a closed circuit.
- the filter system comprises a stretched over two guide rollers endless screen which carries a disposable paper filter belt. One of the rollers is driven by a motor.
- the filter belt is withdrawn from a supply roll, passes through a guide roller on the wire and falls at the other end into a container.
- the invention is therefore an object of the invention to provide a filter device of the above type, which allows for relatively low maintenance and material costs, a permanent and effective cleaning of the dampening solution.
- the filter device is a ring belt filter device comprising a filter belt which is advanceable according to the saturation with dirt particles, wherein the filter belt between a supply station and a collecting station is transportable, and Filter belt U-shaped herumgsPolt around the lower peripheral portion of a trommerlartigen, lying, rotatable arrangement.
- the rotatable assembly is preferably formed of two end disks and a number of these coaxially connecting spacer rods.
- the filter belt Due to its U-shaped arrangement, the filter belt forms a type of pan or trough into which the dampening solution can be introduced.
- the filter band is surrounded at the bottom by a perforated support band, which has a firmer consistency than the filter band and this is supported with respect to the weight of the dampening solution to be filtered.
- the support band is preferably an endless belt which can be transported around rollers in the lower and in the middle to upper region of the circular end discs.
- rollers in the lower and in the middle to upper region of the circular end discs Preferably, two lower and two upper rollers are provided.
- the support band is preferably formed as a link belt, possibly also as a perforated plastic band.
- the ring band filter device according to the invention is particularly suitable as a pre-filter in conjunction with one or two further filters.
- a dirt separation of 50 - 70% is sufficient to relieve the subsequent filter stages.
- the use of a filter fleece from the roll is the most cost effective solution in terms of material consumption. With acceptable dimensions, depending on the pressure conditions, filter material can be stored on the feed roll for about 2-6 weeks, during which time largely automatic operation of the pre-filter is possible.
- the single FIGURE is a schematic perspective view of a filter device according to the invention.
- 10 denotes a cylinder group of a printing press
- the lower roller dampening solution from a dip tank 12 receives and transmits to the other rollers.
- Excess dampening solution runs from the immersion tank 12 via a line 14 in an intermediate container 16.
- a valve 18 in the conduit 14 allows adjustment of the amount of fountain solution flowing through the conduit 14.
- the filter device 24 has as a central component a rotatable, horizontal, perforated drum 26, around the lower portion of which a filter belt 28 is laid, which extends from a supply roll 30 to a collecting roll 32 and from the supply roll to the collecting roll stepwise or continuously corresponding to the entering contamination of the filter material can be advanced.
- the line 20, which emanates from the intermediate container 16 enters the interior of the drum 26.
- the pump 22 therefore pumps the dampening solution from the intermediate container 16 into the drum 26, and from there it penetrates through the perforated drum wall and the material of the filter belt 28 into a collecting container 34 located below the drum.
- an endless support belt 36 is provided, which is wrapped around two respective lower rollers 38, 40 and two upper rollers 42, 44 right and left of the drum according to the drawing.
- This endless support belt 36 is for example a link belt made of plastic or wire, but may also be a perforated plastic film or the like.
- the support belt 36 may form the drive for the arrangement of drum and filter belt, but may also be taken by them.
- the dampening solution penetrates through the perforated drum, the filter belt and the support band on its way into the collecting container 34.
- a filter bag 54 as a further filter device for the dampening solution, which can form the next, finer filter stage. From the dampening solution tank 50, the dampening solution can be conveyed back into the immersion tank 12 via a valve 56, a line 58 and a pump 60.
- the ring band filter device according to the invention is particularly suitable as a pre-filter stage for a 2- or even 3-stage filter system.
- This pre-filter stage should be arranged as close as possible to the dirt entry in the printing unit. It allows automatic, gradual or continuous switching of the filter belt as a function of the saturation with dirt particles.
- the increase of dampening solution within the drum can be used as a measure of the contamination of the filter belt, so that the switching of the filter belt can be controlled automatically.
- a filter stage can then be mounted, for example, in the fountain solution tank, a filter bag at the end of the entering into the tank return pipe.
- a fine filter stage in the form of a pressure filter element in the dampening solution bypass line can be provided as the third filter stage.

Abstract
Description
Die Erfindung betrifft eine Filtervorrichtung für den Feuchtmittelkreislauf einer Offset-Druckmaschine.The invention relates to a filter device for the fountain solution circulation of an offset printing press.
Feuchtmittel werden beim Offset-Druck verwendet zum Befeuchten derjenigen Teile der Oberflächen der Druckplatten, an denen das Annehmen der Farbe verhindert werden soll. Feuchtmittel bestehen in der Regel aus Wasser mit einer Reihe von Zusätzen zur Einstellung der Oberflächenspannung, des PH-Wertes, des Korrosionsverhaltens etc.. Wichtiger Bestandteil ist zumeist Alkohol. Andere Zusatzmittel dienen zur Bestimmung des PH-Wertes zur Bekämpfung von Algen, Pilzen, Bakterien, zur Verhinderung von Korrosion etc..Dampening agents are used in offset printing to moisten those parts of the surfaces of the printing plates where inking is to be prevented. Moisturizers usually consist of water with a number of additives for adjusting the surface tension, the PH value, the corrosion behavior, etc. An important component is usually alcohol. Other additives are used to determine the pH value for controlling algae, fungi, bacteria, preventing corrosion, etc.
Feuchtmittel dieser Art durchlaufen zumeist einen Kreislauf mit einem Feuchtmittelbehälter, einem Vorlauf, einem System zur Befeuchtung des Druckzylinders der Maschine, einem Rücklauf für überschüssiges Feuchtmittel und wenigstens einer Filtereinrichtung im Rücklaufbereich (wie z.B. in
Durch die Filtereinrichtung wird das Feuchtmittel mehr oder weniger von Verunreinigungen befreit, insbesondere von Luftstaub, Papierstaub und Druckfarbenpartikeln. Weil eine gründliche Filtration des Feuchtmittels die Möglichkeit bietet, dieses im Kreislauf wiederholt zu verwenden und damit die Kosten für die Herstellung neuen Feuchtmittels und die Entsorgung des verbrauchten Feuchtmittels zu verringern, werden teilweise auch mehrstufige Filtersysteme eingesetzt. Ein bekanntes Filtersystem zeigt und beschreibt die
Mit Hilfe eines wirksamen Filtersystems ist es durchaus möglich, die Standzeit eines üblichen Feuchtmittels auf das Zwei- oder Dreifache zu verlängern. Andererseits muß auch berücksichtigt werden, daß sich der Kosten- und Wartungsaufwand für das verwendete Filtersystem in angemessenen Grenzen halten muß.With the help of an effective filter system, it is quite possible, the service life of a usual dampening solution to two or three times to extend. On the other hand, it must also be considered that the cost and maintenance of the filter system used must be kept within reasonable limits.
Die
Der Erfindung liegt daher die Aufgabe zugrunde, eine Filtervorrichtung der obigen Art zu schaffen, die bei verhältnismäßig geringen Wartungs- und Materialkosten eine dauerhafte und wirksame Reinigung des Feuchtmittels ermöglicht.The invention is therefore an object of the invention to provide a filter device of the above type, which allows for relatively low maintenance and material costs, a permanent and effective cleaning of the dampening solution.
Diese Aufgabe wird erfindungsgemäß bei einer Filtervorrichtung der obigen Art dadurch gelöst, daß die Filtervorrichtung eine Ringband-Filtereinrichtung ist, die ein Filterband umfaßt, das entsprechend der Sättigung mit Schmutzpartikeln vorrückbar ist, wobei das Filterband zwischen einer Vorratsstation und einer Sammelstation transportierbar ist, und das Filterband U-förmig um den unteren Umfangsbereich einer trommerlartigen, liegenden, drehbaren Anordnung herumgsführt ist.This object is achieved in a filter device of the above type in that the filter device is a ring belt filter device comprising a filter belt which is advanceable according to the saturation with dirt particles, wherein the filter belt between a supply station and a collecting station is transportable, and Filter belt U-shaped herumgsführt around the lower peripheral portion of a trommerlartigen, lying, rotatable arrangement.
Die drehbare Anordnung ist vorzugsweise aus zwei Stirnscheiben und einer Anzahl von diese koaxial verbindenden Abstandsstangen gebildet.The rotatable assembly is preferably formed of two end disks and a number of these coaxially connecting spacer rods.
Aufgrund seiner U-förmigen Anordnung bildet das Filterband eine Art von Wanne oder Mulde, in die das Feuchtmittel eingeleitet werden kann.Due to its U-shaped arrangement, the filter belt forms a type of pan or trough into which the dampening solution can be introduced.
Vorzugsweise wird das Filterband unten durch ein perforiertes Stützband umfangen, das eine festere Konsistenz aufweist als das Filterband und dieses in bezug auf das Gewicht des zu filternden Feuchtmittels abstützt.Preferably, the filter band is surrounded at the bottom by a perforated support band, which has a firmer consistency than the filter band and this is supported with respect to the weight of the dampening solution to be filtered.
Das Stützband ist vorzugsweise ein Endlosband, das um Rollen im unteren sowie im mittleren bis oberen Bereich der kreisförmigen Stirnscheiben transportierbar ist. Vorzugsweise sind zwei untere und zwei obere Rollen vorgesehen.The support band is preferably an endless belt which can be transported around rollers in the lower and in the middle to upper region of the circular end discs. Preferably, two lower and two upper rollers are provided.
Da das Stützband flüssigkeits-durchlässig sein muß, ist das Stützband vorzugsweise als Gliederband, gegebenenfalls auch als gelochtes Kunststoffband ausgebildet.Since the support band must be liquid-permeable, the support band is preferably formed as a link belt, possibly also as a perforated plastic band.
Die erfindungsgemäße Ringband-Filtereinrichtung eignet sich insbesondere als Vorfilter in Verbindung mit einem oder zwei weiteren Filtern. In diesem Falle reicht eine Schmutzabscheidung von 50 - 70 % aus, um die nachfolgenden Filterstufen zu entlasten. Die Verwendung eines Filtervlies von der Rolle stellt die kostengünstigste Lösung in Bezug auf den Materialverbrauch dar. Bei akzeptablen Abmessungen kann in Abhängigkeit von den Druckbedingungen Filtermaterial für ca. 2-6 Wochen auf der Zufuhrrolle vorgehalten werden, so daß während dieser Zeit ein weitgehend automatischer Betrieb des Vorfilters möglich ist.The ring band filter device according to the invention is particularly suitable as a pre-filter in conjunction with one or two further filters. In this case, a dirt separation of 50 - 70% is sufficient to relieve the subsequent filter stages. The use of a filter fleece from the roll is the most cost effective solution in terms of material consumption. With acceptable dimensions, depending on the pressure conditions, filter material can be stored on the feed roll for about 2-6 weeks, during which time largely automatic operation of the pre-filter is possible.
Im folgenden werden bevorzugte Ausführungsbeispiele der Erfindung anhand der beigefügten Zeichnung näher erläutert.In the following preferred embodiments of the invention will be described with reference to the accompanying drawings.
Die einzige Figur ist eine schematische perspektivische Darstellung einer erfindungsgemäßen Filtervorrichtung.The single FIGURE is a schematic perspective view of a filter device according to the invention.
In der Zeichnung ist mit 10 eine Zylindergruppe einer Druckmaschine bezeichnet, deren untere Walze Feuchtmittel aus einer Tauchwanne 12 aufnimmt und auf die anderen Walzen überträgt. Überschüssiges Feuchtmittel läuft von der Tauchwanne 12 über eine Leitung 14 in einen Zwischenbehälter 16. Ein Ventil 18 in der Leitung 14 ermöglicht eine Einstellung der Feuchtmittelmenge, die durch die Leitung 14 strömt.In the drawing, 10 denotes a cylinder group of a printing press, the lower roller dampening solution from a
Über eine weitere Leitung 20, in die eine Pumpe 22 integriert ist, wird Feuchtmittel aus dem Zwischenbehälter 16 in eine Filtereinrichtung 24 überführt. Die Filtereinrichtung 24 weist als zentrales Bauteil eine drehbare, waagerechte, perforierte Trommel 26 auf, um deren unteren Bereich ein Filterband 28 herumgelegt ist, das sich von einer Vorratsrolle 30 bis zu einer Sammelrolle 32 erstreckt und von der Vorratsrolle zur Sammelrolle schrittweise oder kontinuierlich entsprechend der eintretenden Verschmutzung des Filtermaterials vorgerückt werden kann.Via a
In der Zeichnung ist zumindest schematisch angedeutet, daß die Leitung 20, die von dem Zwischenbehälter 16 ausgeht, in das Innere der Trommel 26 eintritt. Die Pumpe 22 pumpt daher das Feuchtmittel aus dem Zwischenbehälter 16 in die Trommel 26, und von hier aus dringt es durch die perforierte Trommelwand und das Material des Filterbandes 28 hindurch in einen unterhalb der Trommel befindlichen Sammelbehälter 34.In the drawing, at least schematically indicated that the
Zur Abstützung des Filterbandes an der Unterseite der Trommel ist ein endloses Stützband 36 vorgesehen, das um jeweils zwei untere Rollen 38, 40 und zwei obere Rollen 42, 44 rechts und links der Trommel gemäß der Zeichnung herumgelegt ist. Dieses endlose Stützband 36 ist beispielsweise ein Gliederband aus Kunststoff oder Draht, kann aber auch eine perforierte Kunststoffolie oder dergleichen sein. Das Stützband 36 kann den Antrieb für die Anordnung aus Trommel und Filterband bilden, kann aber auch ggf. durch diese mitgenommen werden. Das Feuchtmittel dringt auf seinem Weg in den Sammelbehälter 34 durch die perforierte Trommel, das Filterband und das Stützband hindurch.To support the filter belt at the bottom of the drum, an
Von dem Sammelbehälter 34 aus gelangt das nunmehr gefilterte Feuchtmittel durch eine aufsteigende Leitung 46 mit Hilfe einer Pumpe 48 in einen Feuchtmitteltank 50. Am unteren Ende der Leitung 46 befindet sich ein Ventil 52. Innerhalb des Feuchtmitteltanks 50 befindet sich am Ende der Leitung 46 ein Filterbeutel 54 als weitere Filtereinrichtung für das Feuchtmittel, die die nächste, feinere Filterstufe bilden kann. Von dem Feuchtmitteltank 50 aus kann das Feuchtmittel über ein Ventil 56, eine Leitung 58 und eine Pumpe 60 wiederum in die Tauchwanne 12 zurückbefördert werden.From the collecting container 34 from the now filtered dampening passes through an
Wie oben erwähnt wurde, eignet sich die erfindungsgemäße Ringband-Filtereinrichtung insbesondere als Vorfilterstufe für ein 2- oder sogar 3-stufiges Filtersystem. Diese Vorfilterstufe sollte möglichst dicht hinter dem Schmutzeintrag in dem Druckwerk angeordnet werden. Sie ermöglicht eine automatische, schrittwelse oder kontinuierliche Weiterschaltung des Filterbandes in Abhängigkeit von der Sättigung mit Schmutzpartikeln.As mentioned above, the ring band filter device according to the invention is particularly suitable as a pre-filter stage for a 2- or even 3-stage filter system. This pre-filter stage should be arranged as close as possible to the dirt entry in the printing unit. It allows automatic, gradual or continuous switching of the filter belt as a function of the saturation with dirt particles.
Der Anstieg des Feuchtmittels innerhalb der Trommel kann als Maßstab für die Verschmutzung des Filterbandes verwendet werden, so daß die Weiterschaltung des Filterbandes automatisch gesteuert werden kann. Als weitere Filterstufe kann dann beispielsweise im Feuchtmitteltank ein Filterbeutel am Ende des in den Tank eintretenden Rücklaufrohres angebracht sein. Als dritte Filterstufe kann darüber hinaus eine Feinfilterstufe in Form eines Druckfilterelements in der Feuchtmittel-Bypass-Leitung vorgesehen werden.The increase of dampening solution within the drum can be used as a measure of the contamination of the filter belt, so that the switching of the filter belt can be controlled automatically. As a further filter stage can then be mounted, for example, in the fountain solution tank, a filter bag at the end of the entering into the tank return pipe. In addition, a fine filter stage in the form of a pressure filter element in the dampening solution bypass line can be provided as the third filter stage.
