Description

Die Erfindung betrifft eine Vorrichtung zum Waschen des Zylinders einer Druckmaschine mit Hilfe einer Wascheinrichtung, vorzugsweise einer Waschwalze, der in einem Kreislauf ein Waschmittel zugeführt wird, wobei in dem Kreislauf zwischen dem Auslaß und dem Einlaß des Waschmittels der Wascheinrichtung eine Reinigungsvorrichtung für das verschmutzte Waschmittel vorgesehen ist.The invention relates to a device for washing the cylinder of a printing press with the aid of a washing device, preferably a washing roller, to which a detergent is fed in a circuit, a cleaning device for the soiled detergent being provided in the circuit between the outlet and the inlet of the detergent of the washing device is.

Bei bekannten derartigen Waschvorrichtungen wird das verschmutzte Waschmittel überlicherweise mit Hilfe eines mechanischen Filters gereinigt. Hieran ist es aber insbesondere nachteilig, daß das verschmutzte Lösemittel des Waschmittels nur zum Teil durch das Filter gereinigt werden kann. Kleinere Farbpartikel gelangen nämlich wieder in den Kreislauf und setzen daher die Steuerventile, Sprühdüsen, Fittings usf. nach kurzer Zeit außer Funktion. Auch ist es nachteilig, daß mechanische Filteranlagen einen sehr hohen Wartungsaufwand bedingen. Zudem ist das Lösemittel nur für eine begrenzte Zeit einsetzbar und muß in Intervallen gewechselt werden. Nachteilig an diesem Stand der Technik ist es auch, daß das verbrauchte, nicht mehr filterbare Lösemittel durch Sondermüll entsorgt werden muß. Ein weiterer Nachteil besteht darin, daß das mechanische Filter, das aus einer Anhäufung von Faservlies besteht, das mit dem Lösemittel durchtränkt ist, ebenfalls durch Sondermüll entsorgt werden muß.In known washing devices of this type, the dirty detergent is usually cleaned with the aid of a mechanical filter. However, this is particularly disadvantageous in that the soiled solvent of the detergent can only be partially cleaned by the filter. Smaller paint particles come back into the circuit and therefore put the control valves, spray nozzles, fittings etc. out of operation after a short time. It is also disadvantageous that mechanical filter systems require a very high level of maintenance. In addition, the solvent can only be used for a limited time and must be changed at intervals. It is also a disadvantage of this prior art that the used solvent, which can no longer be filtered, must be disposed of as special waste. Another disadvantage is that the mechanical filter, which consists of an accumulation of nonwoven fabric soaked in the solvent, also has to be disposed of in hazardous waste.

Die Erfindung vermeidet diese Nachteile. Ihr liegt die Aufgabe zugrunde, eine Vorrichtung mit den eingangs genannten Merkmalen vorzuschlagen, die sich durch einen fühlbar verringerten Wartungsaufwand auszeichnet, wobei insbesondere Entsorgungsprobleme fühlbar entfallen sollen.The invention avoids these disadvantages. It is based on the object of proposing a device with the features mentioned at the outset, which can be felt by one characterized by reduced maintenance, in particular disposal problems should be felt.

Aus den Patent Abstracts of Japan Vo. 14, No. 271 (M-983)(4214), 12.06.90; JP-A-02-78552 (Dainippon Printing) 19.03.1990 ist eine Vorrichtung zur Reinigung eines Tiefdruckzylinders in einer Druckmaschine bekannt. Danach wird das Lösemittel durch Destillation wieder aufbereitet. Eine Vorrichtung und ein Verfahren zum Waschen einer Offset-Druckmaschine ist aus Dokument US-A-4015307 bekannt.From the Patent Abstracts of Japan Vo. 14, No. 271 (M-983) (4214), 06/12/90; JP-A-02-78552 (Dainippon Printing) March 19, 1990 discloses a device for cleaning an intaglio cylinder in a printing press. The solvent is then reprocessed by distillation. An apparatus and a method for washing an offset printing machine is known from document US-A-4015307.

Zur Losung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die Reinigungsvorrichtung als Destillationsgerät ausgebildet ist, dem ein Sammelbehälter für das verschmutzte Waschmittel vorgeschaltet ist und ein Sammelbehälter für das destillierte Waschmittel nachgeschaltet ist.To achieve this object, the invention is characterized in that the cleaning device is designed as a distillation device, which is preceded by a collecting container for the soiled detergent and a collecting container for the distilled detergent is connected downstream.

Das verschmutzte Waschmittel wird also in dem Kreislauf erfindungsgemäß destilliert, so daß praktisch vollständig gereinigtes Waschmittel (Lösemittel) wieder in den Kreislauf gelangt. Ggf. wird der Lösemittelvorrat über eine geeignete Steuerung mit frischem Lösemittel (Naschmittel) ergänzt, um den Verlusten an Lösemittel durch Verdunsten Rechnung zu tragen. Die Rückstände der Destillation werden von Zeit zu Zeit entsorgt, wobei nur verhältnismäßig geringe Volumina anfallen, weil es sich hierbei um weitgehend eingedickte Rückstände (Farbschlamm) handelt. In der Regel genügt eine Einmalfüllung von Waschmittel.The soiled detergent is thus distilled in the circuit according to the invention, so that virtually completely cleaned detergent (solvent) gets back into the circuit. Possibly. the solvent supply is supplemented with a suitable control system with fresh solvent (sweetener) to take account of the loss of solvent due to evaporation. The residues from the distillation are disposed of from time to time, whereby only relatively small volumes are generated because these are largely thickened residues (colored sludge). As a rule, a single fill of detergent is sufficient.

Die beiden Sammelbehälter kompensieren die Durchlaufzeit des Mediums durch das Destillationsgerät, die einige Stunden betragen kann und stellen somit einen konstanten Waschmittelfluß sicher.The two collection containers compensate for the throughput time of the medium through the distillation device, which can be a few hours, and thus ensure a constant flow of detergent.

Eine geeignete Steuerung oder Regelung ist vorgesehen, die dafür sorgt, daß der Nascheinrichtung (Waschwalze) stets gereinigtes Waschmittel in ausreichender Menge zur Verfügung steht. Teile dieser Steuerung sind Schwimmer, die dafür sorgen, daß die Volumina an Waschmittel in den Sammelbehältern nicht unter ein bestimmtes Niveau absinken.A suitable control or regulation is provided which ensures that the detergent device (washing roller) is always provided with a sufficient amount of cleaned detergent. Parts of this control are floats, which ensure that the volumes of detergent in the collection containers do not drop below a certain level.

Bei einer Mehrfarben-Druckmaschine (Rotations-Druckmaschine) genügt eine erfindungsgemäße Reinigungsvorrichtung für alle Druckwerke der Maschine.In the case of a multicolor printing machine (rotary printing machine), a cleaning device according to the invention is sufficient for all printing units of the machine.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels näher erläutert, aus dem sich weitere wichtige Merkmale ergeben. Es zeigt:

Fig. 1 -
schematisch die wesentlichen Bauelemente einer erfindungsgemäßen Vorrichtung;
Fig. 2 -
die Vorrichtung bei einer Mehrfarben-Druckmaschine.
The invention is explained in more detail below on the basis of an exemplary embodiment from which further important features result. It shows:
Fig. 1 -
schematically the essential components of a device according to the invention;
Fig. 2 -
the device in a multi-color printing press.

Zunächst wird anhand von Fig. 1 das Prinzip der erfindungsgemäßen Vorrichtung erläutert.First, the principle of the device according to the invention is explained with reference to FIG. 1.

Ein Gummizylinder 1 ist vorgesehen, dessen Umfang mit Hilfe einer Waschwalze 2 gereinigt werden kann. Die Waschwalze befindet sich in einem Behälter 3. Über eine Sprühdüse 4 wird die Waschwalze mit einem geeigneten Waschmittelgemisch befeuchtet, wodurch der Gummizylinder gereinigt wird. Fig. 1 zeigt auch einen Aulaß 5, durch den das mit Schmutzpartikel beladene Waschmittelgemisch den Behälter 3 und damit die Wascheinrichtung in Richtung des Pfeiles 6 verläßt.A rubber cylinder 1 is provided, the circumference of which can be cleaned with the aid of a washing roller 2. The washing roller is located in a container 3. The washing roller is moistened with a suitable detergent mixture via a spray nozzle 4, as a result of which the rubber cylinder is cleaned. Fig. 1 also shows an outlet 5 through which the detergent mixture loaded with dirt particles leaves the container 3 and thus the washing device in the direction of arrow 6.

Das verschmutzte Waschmittel gelangt dann in einen Sammelbehälter 7, dem ein Schwimmer 8 und eine Pumpe 9 zugeordnet sind. Es verläßt dann den sammelbehälter 7 über eine Leitung 10 mit einem Volumenzähler 11 und gelangt in ein Destillationsgerät 12.The dirty detergent then passes into a collecting container 7, to which a float 8 and a pump 9 are assigned. It then leaves the collecting container 7 via a line 10 with a volume meter 11 and reaches a distillation device 12.

Dort wird das Waschmittel destilliert und das Destillat gelangt, wie durch die Pfeile 13 angedeutet, über eine Leitung 14 in Richtung des Pfeiles 15 zu einem Frischmittel-Sammelbehälter 16. Auch diesem Sammelbehälter 16 sind ein Schwimmer 17 und eine Pumpe 18 zugeordnet.There, the detergent is distilled and the distillate reaches, as indicated by the arrows 13, via a line 14 in the direction of the arrow 15 to a fresh agent collecting container 16. A float 17 and a pump 18 are also assigned to this collecting container 16.

Von dort gelangt das gereinigte Waschmittel über eine Leitung 19 in Richtung des Pfeiles 20 wieder zum Einlaß des Behälters 3, wobei in der Leitung 19 ein Steuerventil 21 vorgesehen ist.From there, the cleaned detergent reaches the inlet of the container 3 again via a line 19 in the direction of the arrow 20, a control valve 21 being provided in the line 19.

Das vorstehend skizzierte Prinzip wird auch bei einer Mehrfarben-Rotations-Druckmaschine verwirklicht, wie sie in Fig. 2 skizziert ist. Daraus ist auch ersichtlich, daß jedes der Druckwerke der Maschine über geeignete Zweigleitungen 19a mit dem gereinigten Waschmittel (Frischmittel) versorgt wird und über weitere Zweigleitungen 22a, die in eine gemeinsame Sammelleitung 22 einmünden, wird die erfindungsgemäße Reinigungsvorrichtung mit dem Sammelbehälter 7, dem Destillationsgerät 12 und dem Sammelbehälter 16 vorsorgt.The principle outlined above is also implemented in a multicolor rotary printing press, as outlined in FIG. 2. It can also be seen from this that each of the printing units of the machine is supplied with the cleaned detergent (fresh agent) via suitable branch lines 19a and the cleaning device according to the invention with the collecting container 7, the distillation device 12, is connected via further branch lines 22a, which open into a common collecting line 22 and the collection container 16 provides.

Es ist somit ersichtlich, daß das verschmutzte Waschmittel (Lösemittel) von Farbresten, Papierstaub, Papierresten, Wasser und Kalk völlig sauber gereinigt und getrennt wird. Es steht somit immer absolut sauberes Lösemittel zur Verfügung und kann wieder benutzt werden. Auch bedarf diese Methode keinerlei Fremdentsorgung. Die (trockenen oder vorzugsweise noch flüssigen) Rückstände im Gerät 12 können vielmehr als Industriemüll entsorgt werden; sie sind kein Sondermüll.It can thus be seen that the soiled detergent (solvent) is completely cleanly cleaned of color residues, paper dust, paper residues, water and lime and separated. Absolutely clean solvent is therefore always available and can be used again. This method also does not require any external disposal. The (dry or preferably still liquid) residues in the device 12 can rather be disposed of as industrial waste; they are not hazardous waste.

Das Destillationsgerät 12 wird vorzugsweise über geeignete Schlangen elektrisch beheizt, die sowohl den Boden wie auch die Wände des Geräts erwärmen. Die Dämpfe gelangen dann durch die Leitung 14 in den Sammelbehälter 16. Es handelt sich um eine fraktionierte Destillation und im Sammelbehälter 16 werden die Fraktionen wieder gemischt. Es sei in diesem Zusammenhang erwähnt, daß es sich um ein Waschmittel auf der Basis von Kohlenwasserstoffen handelt.The distillation device 12 is preferably electrically heated by means of suitable coils which heat both the floor and the walls of the device. The vapors then arrive through line 14 into the collecting tank 16. It is a fractional distillation and the fractions are mixed again in the collecting tank 16. It should be mentioned in this connection that it is a detergent based on hydrocarbons.

Ein weiterer wichtiger Vorteil besteht darin, daß das verwendete Wasser - nach dem ersten Durchlauf -kalkfrei ist, weil es sich um destilliertes Wasser handelt, die insoweit empfindlichen Teile der Waschvorrichtung, insbesondere die Sprühdüsen, können also nicht mehr verkalken und die Anlage zeichnet sich auch aus diesem Grunde durch eine fühlbar verlängerte Lebensdauer und einen wesentlich verringerten Wartungsaufwand aus.Another important advantage is that the water used - after the first pass - is lime-free, because it is distilled water, so the sensitive parts of the washing device, especially the spray nozzles, can no longer calcify and the system also stands out For this reason, it has a noticeably longer service life and significantly reduced maintenance.

Wichtig ist es auch, daß die eigentliche Waschvorrichtung ohne ein Waschtuch auskommt, damit das Waschmittel in einem Kreislauf wieder zurückfließen kann. Bei Verwendung eines Waschtuchs, wie dies bei einigen Waschvorrichtungen der Fall ist, würde das Waschmittel im Waschtuch verbleiben, was aus den geschilderten Gründen nachteilig wäre.It is also important that the actual washing device does not need a washcloth so that the detergent can flow back in a cycle. When using a washcloth, as is the case with some washing devices, the detergent would remain in the washcloth, which would be disadvantageous for the reasons described.

Das Destillationsgerät benötigt bei einer Menge von etwa 80 Litern an Waschmittel ca. 6 bis 7 Stunden zum Destillieren. Aus diesem Grunde wird dem Destillationsgerät 12 der Sammelbehälter 16 nachgeschaltet, in dem sich ausreichend frisches Waschmittel ansammeln kann, das dann über die Pumpe 18 den Sprühdüsen 4 wieder zugeführt wird. Der Sammelbehälter 7 dient dazu, eine ausreichende Menge an verbrauchtem Waschmittel anzusammeln, bis dieses, gesteuert über das Ventil 11, in das Gerät 12 gegeben wird, sobald das Gerät für einen neuen Destillationsvorgang wieder bereit ist.With a quantity of about 80 liters of detergent, the distillation unit takes about 6 to 7 hours to distill. For this reason, the distillation device 12 is followed by the collection container 16, in which sufficient fresh detergent can accumulate, which is then returned to the spray nozzles 4 via the pump 18. The collecting container 7 serves to accumulate a sufficient amount of used detergent until it, controlled by the valve 11, is added to the device 12 as soon as the device is ready for a new distillation process.

Es wäre aber auch denkbar, das Gerät 12 so auszulegen, daß mit ihm kontinierlich destilliert werden kann.However, it would also be conceivable to design the device 12 in such a way that it can be distilled continuously.
