Description

Die Erfindung bezieht sich auf eine Einrichtung zum Reinigen eines an einer Stahlstichdruckmaschine befindlichen Wischzylinders mit einem Behälter für das Reinigungsmittel, mit an diesem befindlichem Einlauf für das Reinigungsmittel, einer mit einer Pumpe versehenen Einrichtung zum Regenieren des Reinigungsmittels und einem an dem Reinigungsmittelbehälter befindlichen Einlauf für das regenierte Reinigungsmittel.The invention relates to a device for cleaning a wiping cylinder located on a steel engraving printing press with a container for the cleaning agent, with an inlet for the cleaning agent located thereon, a device provided with a pump for regenerating the cleaning agent and an inlet for the cleaning agent container regenerated detergent.

Eine Einrichtung der umrissenen Art ist aufgrund der DE-AS 12 29 547 bekannt. Diese Einrichtung besitzt eine Klärkammer zum Zwecke des Regenerierens des Reinigungsmittels, Diese Klärkammer ist jedoch bei dem außerordentlich hohen Anfall an Farbstoffen, welche beim Reinigen des Formzylinders von Stahlstichdruckmaschinen anfallen, nur in recht unvollkommener Weise geeignet, das sogenannte Wischmittel zum Reinigen des Formzylinders zu regenieren, sofern die Klärkammer - was unter praktischen Bedingungen immer gegeben ist - nicht allzu große Abmessungen aufweisen soll. Dadurch, daß die Größe der Klärkammer unter praktischen Bedingungen begrenzt ist, wird das Reinigungsmittel durch eine Klärkammer nur unvollkommen gereinigt, was wiederum bedeutet, daß sie sich sehr schnell mit Farbe anreichert und nur relativ kurze Zeit verwendet werden kann.A device of the outlined type is known from DE-AS 12 29 547. This device has a clarifying chamber for the purpose of regenerating the cleaning agent. However, this clarifying chamber is only in a rather imperfect way to regenerate the so-called wiping agent for cleaning the forming cylinder given the extraordinarily high amount of dyes which arise when cleaning the form cylinder of steel engraving printing machines. provided that the clarification chamber - which is always the case under practical conditions - should not have too large dimensions. Because the size of the clarification chamber is limited under practical conditions, the cleaning agent is only incompletely cleaned by a clarification chamber, which in turn means that it accumulates with color very quickly and can only be used for a relatively short time.

Wegen des sehr hohen Anteils von Farbe ist die Kapazität der Klärkammer sehr schnell erschöpft, weshalb die Klärkammer in relativ kurzen zeitlichen Intervallen gereinigt werden muß. Dies bedeutet einen fortlaufenden hohen Bedienungsaufwand. Analoges gilt für die Verwendung von Durchlauffiltern. Diese Filter setzen sich beim Betrieb der Einrichtung sehr schnell zu, so daß auch diese Filter in recht kurzen zeitlichen Intervallen gewechselt werden müssen,Because of the very high proportion of color, the capacity of the clarification chamber is exhausted very quickly, which is why the clarification chamber must be cleaned in relatively short time intervals. This means an ongoing high operating effort. The same applies to the use of flow filters. These filters clog up very quickly when the device is in operation, so that these filters also have to be changed at very short time intervals,

Es besteht daher die Aufgabe, die Standzeit des Reinigungsmittels zu verlängern,There is therefore the task of extending the service life of the cleaning agent,

Diese Aufgabe wird durch das in den Patentansprüchen umrissene Patentbegehren gelöst.This object is achieved by the patent request outlined in the patent claims.

Durch die erfindungsgemäße Verwendung eines Separators zum Reinigen des Reinigungsmittels wird dieses während des Laufes der Stahlstichdruckmaschine kontinuierlich gereinigt. Dabei ist der Reinigungseffekt wesentlich größer als mit Hilfe der bisher verwendeten Klärkammern oder Durchlauffilter. Das Reinigen verstopfter Filter oder Klärkammern wird vollkommen vermieden. Desgleichen wird die Standzeit des Reinigungsmittels, d.h. diejenige Zeit, in welcher das Reinigungsmittel seinerseits rein genug ist, um den Wischzylinder der Stahlstichdruckmaschine zu reinigen, wesentlich verlängert, Die kurzen Zeiten, welche notwendig sind, um den Separator selbst zu-reinigen, sind sehr kurz, Aufgrund der ebenfalls vorgeschlagenen Schaltung werden diese Zeiten zudem noch dadurch überbrückt, daß relativ gut gereinigtes Reinigungsmittel umgewälzt werden kann, wohingegen relativ schlecht gereinigtes Reinigungsmittel für diesen kurzen Zeitraum nicht verwendet wird, Die Zeiten, in welchen der Separator selbst gereinigt wird, werden bei Verwendung eines sogenannten selbstreinigenden Separators noch um ein weiteres verkürzt, Auf diese Weise wird ein vollkommen kontinuierlicher Betrieb der Wischeinrichtung und damit der Stahlstichdruckmaschine selbst erzielt, Die erfindungsgemäße Einrichtung ist in einer den Erfindungsgedanken nicht begrenzenden Weise in einem Ausführungsbeispiel in der beigefügten Fig. schematisch abgebildet. In der Fig. sind im vorliegenden Zusammenhang nicht wesentliche Maschinenteile wegen einer übersichtlicheren Darstellungsweise nicht gezeichnet, da sie dem Fachmann ohnehin hinreichend bekannt sind,The inventive use of a separator for cleaning the cleaning agent cleans it continuously while the steel engraving printing press is running. The cleaning effect is much greater than with the help of the clarification chambers or flow filters used so far. The cleaning of clogged filters or clarification chambers is completely avoided. Likewise, the service life of the cleaning agent, ie the time in which the cleaning agent itself is clean enough to clean the wiping cylinder of the steel engraving printing machine, is significantly extended. The short times required to clean the separator itself are very short Due to the circuit also proposed, these times are also bridged by the fact that relatively well cleaned cleaning agent can be circulated, whereas relatively poorly cleaned cleaning agent is not used for this short period of time. The times in which the separator itself is cleaned become in use of a so-called self-cleaning separator is shortened even further. In this way, a completely continuous operation of the wiping device and thus of the steel engraving printing machine itself is achieved, The device according to the invention is shown schematically in an exemplary embodiment in the attached FIG. In a manner that does not limit the inventive concept. In the present context, machine parts that are not essential are not shown in the figure because of a clearer representation, since they are already sufficiently known to the person skilled in the art

Zum Reinigen des Formzylinders 1 einer Stahlstichdruckmaschine zum Herstellen von Wertscheinen, beispielsweise Banknoten oder Briefmarken, berührt ein Wischzylinder 2 die Oberfläche des Formzylinders 1. Der Wischzylinder kann dabei angetrieben sein und derart umlaufen, daß er an der Berührungsstelle von Formzylinder und Wischzylinder zu der Oberfläche des Formzylinders 1 gegenläufig oder gleichläufig umläuft.For cleaning the forme cylinder 1 of a steel engraving printing machine for producing notes of value, for example banknotes or stamps, a wiper cylinder 2 touches the surface of the forme cylinder 1. The wiper cylinder can be driven and revolve in such a way that it touches the surface of the forme cylinder and wiper cylinder Forme cylinder 1 rotates in the opposite or the same direction.

Der Wischzylinder 2 ist mindestens teilweise von einem Behälter 3 für die Aufnahme der Reinigungsflüssigkeit umgeben. Diese Reinigungsflüssigkeit wird in Fachkreisen weitgehend auch als "Wischflüssigkeit" bezeichnet. An dem Behälter 3 sind mindestens zwei Ablaufstellen 4 und 5 vorgesehen, mit deren Hilfe die in dem Behälter 3 anstehende Reinigungsflüssigkeit 6 ablaufen kann. Vom Boden 7 des Behälters 3 ist die Ablaufstelle 4 um den Abstand 8 und die Ablaufstelle 5 um den Abstand 9 entfernt, Der Abstand 8 kann auch das Maß Null annehmen, so daß die Ablaufstelle 4 an der untersten Stelle des Behälters 3 liegt, Auf diese Weise sind die Ablaufstellen auch untereinander so angeordnet, daß sie die Reinigungsflüssigkeit 6 aus unterschiedlichen Niveaus aus dem Behälter 3 abführen können.The wiping cylinder 2 is at least partially surrounded by a container 3 for holding the cleaning liquid. This cleaning liquid is largely referred to in specialist circles as "wiping liquid". At least two drain points 4 and 5 are provided on the container 3, with the aid of which the cleaning liquid 6 present in the container 3 can drain off. From the bottom 7 of the container 3, the drainage point 4 is at a distance of 8 and the drainage point 5 is at a distance of 9, the distance 8 can also be zero, so that the drainage point 4 is at the lowest point of the container 3, on this The drainage points are also arranged one below the other in such a way that they can discharge the cleaning liquid 6 from the container 3 from different levels.

Der Ablaufstelle 4 ist eine Leitung 10 und der Ablaufstelle 5 eine Leitung 11 zugeordnet. Die Leitungen 10 und 11 sind mit dem ersten Dreiwegeventil 12 verbunden, -während eine Pumpe 13 zwischen dem ersten Dreiwegeventil 12 und dem zweiten Dreiwegeventil 14 angeordnet ist. Zwischen dem zweiten Dreiwegeventil 14 und der Zulaufstelle 15 für das regenerierte Reinigungsmittel ist ein mehrere Komponenten eineskolloidalen Flüssigkeitsgemisches oder Flüssigkeit-Feststoffgemisches mit Hilfe der Fliehkraft arbeitender, nach Art einer Zentrifuge umlaufender Separator 16 angeordnet, welcher ein sogenannter selbstreinigender Separator sein kann, Vom Seperator 16 führt eine Leitung 17 zu der Zulaufstelle 15. Aufgrund der Verbindungsleitungen ist der Separator 16 nicht allein zwischen der Pumpe 13 oder den Dreiwegeventilen 12 und 14 und der Zulaufstelle 15, sondern auch zwischen der Ablaufstelle 4 und der Zulaufstelle 15 angeordnet, Ferner führt eine Leitung 18 von dem zweiten Dreiwegeventil 14 zu der Leitung 17. Zwischen dem Separator 16 und der Einmündung der Leitung 18 in die Leitung 17 ist ein Absperrventil 19 angebracht.A drain 10 is assigned to drain 4 and a drain 11 to drain 5. The lines 10 and 11 are connected to the first three-way valve 12, while a pump 13 is arranged between the first three-way valve 12 and the second three-way valve 14. Between the second three-way valve 14 and the inlet point 15 for the regenerated cleaning agent, a plurality of components of a colloidal liquid mixture or liquid-solid mixture is arranged by centrifugal force and operates in the manner of a centrifuge, which separator 16 can be a so-called self-cleaning separator a line 17 to the inlet point 15. Because of the connecting lines, the separator 16 is not only arranged between the pump 13 or the three-way valves 12 and 14 and the inlet point 15, but also between the outlet point 4 and the inlet point 15. Furthermore, a line 18 leads from the second three-way valve 14 to the line 17. A shut-off valve 19 is attached between the separator 16 and the confluence of the line 18 into the line 17.

Während des normalen Betriebsablaufes läuft die Reini- gungsflüssigkeit aus dem Behälter 3 über die Ablaufstelle 4 in die Leitung 10, passiert das erste Dreiwegeventil 12 bei einer Ventilstellung derart, daß die Leitung 11 gesperrt ist, gelangt danach in die Pumpe 13, dann in das zweite Dreiwegeventil 14, welches so geschaltet ist, daß die Leitung 18 gesperrt ist, um danach dem Separator 16 zuzulaufen. Dort wird das Reinigungsmittel seinerseits gereinigt, Nach dem Reinigungsvorgang läuft das gereinigte Reinigungsmittel durch das geöffnete Ventil 19 und die Leitung 17 an die Zulaufstelle 15, um in gereinigter Förm wieder ih den Behälter 3 eintreten zu können.During the normal operating sequence, the cleaning liquid runs from the container 3 via the drainage point 4 into the line 10, passes the first three-way valve 12 with a valve position such that the line 11 is blocked, then passes into the pump 13, then into the second Three-way valve 14, which is switched so that the line 18 is blocked to then run to the separator 16. The cleaning agent is in turn cleaned there. After the cleaning process, the cleaned cleaning agent runs through the opened valve 19 and the line 17 to the inlet point 15 in order to be able to re-enter the container 3 in a cleaned form.

Wenn der Separator seinerseits gereinigt werden soll, was relativ kurze Zeit insbesondere dann beansprucht, Wenn es ein selbstreinigender Separator ist, wird das Dreiwegeventil 12 derart verstellt, daß es die Leitung 11-mit der Pumpe 13 verbindet und den Durchfluß durch die Leitung 10 sperrt. Das zweite Dreiwegeventil 14 wird gleichzeitig derart verstellt, daß es die Pumpe 13 mit der Leitung 18 verbindet und den Zulauf zum Separator 16 sperrt, während das Ventil 19 ebenfalls gesperrt wird. Auf diese Weise wird die Reinigungsflüssigkeit für den kurzen Zeitraum des Reinigens des Seperators an einer relativ weit oben gelegenen Stelle des Behälters 3 entnommen. Dies ist eine Stelle, an der relativ reines Reinigungsmittel in dem Behälter 3 ansteht im Gegensatz zu der Position der Ablaufstelle 4, an welcher relativ verschmutztes Reinigungsmittel anzutreffen ist.If the separator itself is to be cleaned, which takes a relatively short time, particularly if it is a self-cleaning separator, the three-way valve 12 is adjusted such that it connects the line 11 to the pump 13 and blocks the flow through the line 10. The second three-way valve 14 is simultaneously adjusted in such a way that it connects the pump 13 to the line 18 and blocks the inlet to the separator 16, while the valve 19 is also blocked. In this way, the cleaning liquid is removed from the container 3 at a relatively high point for the short period of time for cleaning the separator. This is a point at which relatively pure cleaning agent is present in the container 3, in contrast to the position of the drainage point 4 at which relatively dirty cleaning agent can be found.

Wenn die Ventile in dem zuletzt genannten Sinne verstellt worden sind, kann der Separator 16 schnell gereinigt werden. Nach der Reinigung des Separators werden die Dreiwegeventile 12 und 14 sowie das Ventil 19 wieder umgestellt, damit der ursprüngliche Kreislauf des Reinigungsmittels wieder eingehalten werden kann.If the valves have been adjusted in the latter sense, the separator 16 can be cleaned quickly. After cleaning the separator, the three-way valves 12 and 14 and the valve 19 are switched over again so that the original circuit of the cleaning agent can be maintained again.
