  • the knife disk 66 must be radially inserted close to the wipe roll 34 through the wipe roll 64 and must also be transported over the entire length of the wipe roll.

Der in Fig. 1 dargestellte Wickelstand 2 nach der Erfindung hat ein fahrbares Gestell 4 auf Rollen 6. Auf dem Gestell 4 befindet sich eine erste Lagervorrichtung 8 zur drehbaren Lagerung einer Vorratsrolle 10 für eine Waschtuchbahn 12, dessen Breite im wesentlichen der Breite eines zu reinigenden Rotationskörpers 14 der betreffenden Druckmaschine von Fig. 2 entspricht und dessen Länge ein vielfaches der Länge von einem auf eine Saubertuchrolle 18 gewickelten Waschtuchs 20 ist.The winding stand 2 shown in FIG. 1 according to the invention has a mobile frame 4 on rollers 6. On the frame 4 there is a first bearing device 8 for the rotatable mounting of a supply roll 10 for a washcloth web 12, the width of which essentially corresponds to the width of one to be cleaned Rotating body 14 corresponds to the relevant printing machine of FIG. 2 and its length is a multiple of the length of a wash cloth 20 wound on a cleaning cloth roll 18.

Der Rotationskörper 14 der Druckmaschine ist vorzugsweise ein Druckbildübertragungszylinder, was heute üblicherweise ein Gummituchzylinder ist, ein Gegendruckzylinder, ein Druckplattenzylinder oder eine Rolle oder Walze, beispielsweise eine Farbwerkswalze zur Übertragung von Farbe auf den Druckplattenzylinder oder eine Feuchtwerkswalze zur Übertragung von Befeuchtungsflüssigkeit auf einen der Druckwerkszylinder.The rotary body 14 of the printing press is preferably a printing image transfer cylinder, which is usually a blanket cylinder today, an impression cylinder, a printing plate cylinder or a roller or roller, for example an inking roller for transferring ink to the printing plate cylinder or a dampening roller for transferring dampening liquid to one of the printing unit cylinders.

Auf dem Gestell 4 befindet sich ferner eine zweite Lagervorrichtung 22, in welcher die Saubertuchrolle 18 mit Abstand von der Vorratsrolle 10 und parallel zu ihr angeordnet ist. An der zweiten Lagervorrichtung 22 ist eine Kurbel 24 zum Drehen der Saubertuchrolle 18 angeordnet, so daß durch Drehen der Saubertuchrolle 18 eine bestimmte Länge Waschtuch 12 von der Vorratsrolle 10 als Waschtuch 20 auf die Saubertuchrolle 18 gewickelt werden kann. Anstelle einer Handkurbel 24 könnte auch ein Motor verwendet werden.On the frame 4 there is also a second bearing device 22 in which the cleaning cloth roll 18 is arranged at a distance from the supply roll 10 and parallel to it. On the second bearing device 22, a crank 24 for rotating the cleaning cloth roll 18 is arranged, so that a certain length of washing cloth 12 can be wound from the supply roll 10 as a washing cloth 20 onto the cleaning cloth roll 18 by rotating the cleaning cloth roll 18. Instead of a hand crank 24, a motor could also be used.

Ein erstes Messer 26 dient zum Trennen des von der Vorratsrolle 10 zur Saubertuchrolle 18 sich erstreckenden Waschtuchabschnittes 28.A first knife 26 serves to separate the wash cloth section 28 which extends from the supply roll 10 to the clean cloth roll 18.

Die Saubertuchrolle 18 mit dem sauberen Waschtuchwickel 20 wird anschließend in eine Wascheinheit 30 eingesetzt, in welcher das saubere Waschtuch 20 von der Saubertuchrolle 18 über ein Andrückelement 32 auf eine Schmutztuchrolle 34 gewickelt wird, so daß ein Schmutztuchwickel 37 gebildet wird. Das Andrückelement 32 drückt das Waschtuch 20 an die Mantelfläche 35 des Zylinders 14, wenn in einer Druckluftkammer 36 ein bestimmter Luftdruck erzeugt wird, welcher auf das Andruckelement 32 wirkt. Die Höhe des Luftdruckes in der Druckluftkammer 36 des Andrückelementes 32 bestimmt die Kraft, mit welcher das Andrückelement 32 das Waschtuch 20 gegen den Zylinder 14 drückt. Das Waschtuch 20 wird in bekannter Weise mit Flüssigkeit einer Flüssigkeitsabgabevorrichtung, z.B. Düsen 38 befeuchtet. Die Wascheinheit 30 hat eine balkenförmig längliche Form von ungefähr der gleichen Länge wie der Zylinder 14 und ist mittels Bolzen 40 an einem Seitenrahmen 42 der Druckmaschine lösbar befestigt. Von den beiden Seitenrahmen 42 ist in Fig. 2 nur einer dargestellt. Die Vorderkante der Bolzen 42 liegt jeweils an einer Anschlagfläche 44 eines Trägers 46 der Wascheinheit 30 an. Die Anschlußfläche 44 zeigt vom Zylinder 14 weg. Dadurch stützt sich der vom Andrückelement 32 auf den Zylinder 14 ausgeübte Druck über die Anschlagflächen 44 an beiden stirnseitigen Enden der Wascheinheit 30 an den Bolzen 40 ab. Die Anschlagflächen 44 sind durch die nach hinten zeigenden Flächen von Aufnahmeöffnungen 48 der Träger 46 gebildet. Bei allen Druckwerken ist der Abstand "y" zwischen dem Bolzen 40 bzw. der Anschlagfläche 44 und dem Zylinder 14 gleich groß. Der Abstand "y" wird im folgenden Zylinder-Maschinenabstand genannt. Der vom Andrückelement 32 auf den Zylinder 14 ausgeübte Druck sollte bei einem bestimmten Luftdruck in der Druckluftkammer 36 immer gleich groß sein. Dies ist jedoch nicht der Fall, weil sowohl Herstellungstoleranzen der Vorrichtungsteile als auch die Elastizität des Andrückelementes 32 von Waschbalken zu Waschbalken 30 verschieden sind. In einer Druckmaschine sind meistens mehrere Waschbalken auf mehrere Zylinder verteilt angeordnet. Das Andrückelement 32 besteht vorzugsweise aus einem Band oder Schlauch aus elastischem Material, beispielsweise Gummi oder Kunststoff, geschäumtem Kunststoff oder sonstigem elastischem Material, welches von einem Halter 50 in der Wascheinheit 30 gehalten wird. Im Falle eines Schlauches bildet er selbst die Druckkammer 36. Bei einer anderen Ausführungsform können ein streifenförmiges elastisches Andrückelement und darauf wirkende, durch Druckluft betätigte Andrückkolben vorgesehen sein. Zum Ausgleich der Herstellungstoleranzen und der unterschiedlichen Flexibilität der Andrückelemente 32 zwischen verschiedenen Wascheinheiten 30 in der Weise, daß bei einem bestimmten Luftdruck auch ein ganz bestimmter Anpreßdruck am Zylinder 14 erzeugt wird, ist es erforderlich, den Halterabstand "x" zwischen dem Halter 50 und den Bolzen 40 für jede Wascheinheit 30 so einzustellen, daß bei allen Wascheinheiten bei einem bestimmten Luftdruck der gleiche Anpreßdruck des Andrückelements 32 am Zylinder 14 erzeugt wird. Dazu können Stellschrauben 52 verwendet werden, mittels welchen der Abstand des Halters 50 von einem ortsfesten Element 54 eingestellt werden kann, welches mit Bezug auf die Träger 46 ortsfest angeordnet ist oder in bestimmten Positionen positionierbar ist.The clean cloth roll 18 with the clean wash cloth roll 20 is then inserted into a washing unit 30, in which the clean wash cloth 20 is wound from the clean cloth roll 18 via a pressing element 32 onto a dirty cloth roll 34, so that a dirty cloth roll 37 is formed. The pressing element 32 presses the washcloth 20 against the outer surface 35 of the cylinder 14 when a certain air pressure is generated in a compressed air chamber 36, which acts on the pressing element 32. The level of the air pressure in the compressed air chamber 36 of the pressure element 32 determines the force with which the pressure element 32 presses the washcloth 20 against the cylinder 14. The washcloth 20 is moistened in a known manner with liquid from a liquid dispensing device, for example nozzles 38. The washing unit 30 has a bar-shaped, elongated shape of approximately the same length as the cylinder 14 and is detachably fastened to a side frame 42 of the printing press by means of bolts 40. Only one of the two side frames 42 is shown in FIG. 2. The front edge of the bolts 42 lies against a stop surface 44 of a carrier 46 of the washing unit 30. The pad 44 faces away from the cylinder 14. As a result, the pressure exerted by the pressing element 32 on the cylinder 14 is supported on the bolts 40 via the stop surfaces 44 on both front ends of the washing unit 30. The stop surfaces 44 are formed by the rear-facing surfaces of receiving openings 48 in the carrier 46. In all printing units, the distance "y" between the pin 40 or the stop surface 44 and the cylinder 14 is the same. The distance "y" becomes the following cylinder-machine distance called. The pressure exerted on the cylinder 14 by the pressing element 32 should always be the same at a certain air pressure in the compressed air chamber 36. However, this is not the case because both the manufacturing tolerances of the device parts and the elasticity of the pressing element 32 differ from wash bar to wash bar 30. In a printing press, several wash bars are usually distributed over several cylinders. The pressure element 32 preferably consists of a band or hose made of elastic material, for example rubber or plastic, foamed plastic or other elastic material, which is held by a holder 50 in the washing unit 30. In the case of a hose, it itself forms the pressure chamber 36. In another embodiment, a strip-shaped elastic pressure element and pressure pistons actuated by compressed air and acting thereon can be provided. In order to compensate for the manufacturing tolerances and the different flexibility of the pressing elements 32 between different washing units 30 in such a way that a certain contact pressure is also generated on the cylinder 14 at a certain air pressure, it is necessary to change the holder distance "x" between the holder 50 and the Adjust the bolt 40 for each washing unit 30 so that the same contact pressure of the pressing element 32 on the cylinder 14 is generated for all washing units at a certain air pressure. For this purpose, set screws 52 can be used, by means of which the distance of the holder 50 from a fixed element 54 can be set, which is arranged fixed with respect to the carrier 46 or can be positioned in certain positions.

Fig. 3 zeigt in einem Querschnitt längs der Ebene III-III von Fig. 2, daß das Andrückelement 32 anstelle die Form eines Schlauches auch die Form eines elastischen Bandes haben kann, welches zusammen mit dem Halter 50 eine Druckluftkammer 36 bildet, durch deren Druckluft das Andrückelement 32 in Richtung zum Zylinder 14 expandierbar ist.Fig. 3 shows in a cross section along the plane III-III of Fig. 2 that the pressing element 32 instead of the shape of a tube also the shape of an elastic band can have, which together with the holder 50 forms a compressed air chamber 36, by means of which compressed air the pressing element 32 can be expanded in the direction of the cylinder 14.

Ferner zeigt Fig. 3, daß das ortsfeste Element 54 mit stirnseitigen Seitenteilen 56 der Wascheinheit 30 verbunden ist. Die Seitenteile 56 können relativ zu den seitlichen Trägern 46 in Richtung zum Zylinder 14 verschiebbar und in bestimmten Positionen durch einen Bolzen 58 fixierbar sein. Dadurch kann durch Verschieben der Seitenteile 56 relativ zu den Trägern 46 der Halter 50 in Richtung zum Zylinder 14 verstellt werden, anstelle mittels der Stellschrauben 52, um den Halterabstand "x" zu verändern und um dadurch zwischen dem Andrückelement 32 und dem Zylinder 14 einen vorbestimmten Anpreßdruck zu erzeugen, korrespondierend zu einem vorbestimmten Luftdruck in der Druckluftkammer 36. Das in Fig. 3 nicht dargestellte linke stirnseitige Ende ist gleich ausgebildet wie das in Fig. 3 rechts dargestellte stirnseitige Ende, so daß an beiden stirnseitigen Enden je ein Seitenteil 56 und ein Träger 46 vorgesehen sind, die relativ zum Zylinder 14 und relativ zueinander verstellbar sind. Fig. 3 zeigt außerdem einen ersten Druckluftanschluß 60 zum schrittweisen Antrieb der Schmutztuchrolle 34 mittels Druckluft und zum Erzeugen eines vorbestimmten, vorzugsweise einstellbaren, Luftdrucks in der Druckluftkammer 36.3 also shows that the fixed element 54 is connected to front side parts 56 of the washing unit 30. The side parts 56 can be displaced relative to the side supports 46 in the direction of the cylinder 14 and can be fixed in certain positions by a bolt 58. As a result, by moving the side parts 56 relative to the carriers 46, the holder 50 can be adjusted in the direction of the cylinder 14, instead of by means of the adjusting screws 52, in order to change the holder distance "x" and thereby thereby a predetermined between the pressure element 32 and the cylinder 14 Generate contact pressure, corresponding to a predetermined air pressure in the compressed air chamber 36. The left front end, not shown in FIG. 3, is designed in the same way as the front end shown in FIG. 3 on the right, so that a side part 56 and a at each end end Carriers 46 are provided which are adjustable relative to the cylinder 14 and relative to one another. FIG. 3 also shows a first compressed air connection 60 for the step-by-step drive of the dirty tissue roller 34 by means of compressed air and for generating a predetermined, preferably adjustable, air pressure in the compressed air chamber 36.

Auf dem Gestell 4 des in Fig. 1 dargestellten Wickelstandes 2 befindet sich eine dritte Lagervorrichtung 62 zur drehbaren Lagerung einer Schmutztuchrolle 34 mit einem darauf aufgewickelten schmutzigen Waschtuch 37, welches das Waschtuch 20 der Saubertuchrolle 18 der Fig. 2 und 3 ist, nachdem es vom Zylinder 4 Schmutz abgewischt und auf die Schmutztuchrolle 34 aufgewickelt wurde.On the frame 4 of the winding stand 2 shown in Fig. 1 there is a third bearing device 62 for rotatably mounting a roll of dirty cloth 34 with a dirty wash cloth 37 wound thereon, which is the wash cloth 20 of the clean cloth roll 18 of FIGS. 2 and 3 after it has been removed Cylinder 4 dirt was wiped and wound onto the dirty cloth roll 34.

Im Gestell 4 sind Schneidmittel, beispielsweise in Form einer von einem Elektromotor 67 angetriebenen rotierenden Messerscheibe 66, untergebracht, welche durch eine Transportvorrichtung 68 längs der Schmutztuchrolle 34 motorisch bewegt werden können, um den Schmutztuch-Wickel 37 bis zur Schmutztuchrolle 34 in axialer Längsrichtung aufzuschneiden. Dabei muß die Messerscheibe 66 bis nahe auf die Schmutztuchrolle 34 durch den Schmutztuchwickel 64 radial eingeführt und auch über die gesamte Länge der Schmutztuchrolle transportiert werden. Dabei ergeben sich viereckige Schmutztuchstücke, welche eine dem Schmutztuch-Wickel 37 und damit auch eine im wesentlichen der Länge des Zylinders 14 entsprechende Länge haben. Diese Schmutztuchstücke fallen, nachdem der Schmutztuch-Wickel 37 axial aufgeschnitten wurde, entweder selbständig oder durch Unterstützung von Hand oder maschinell, auf ein unter der Schmutztuchrolle 34 angeordnetes Auffangblech 70. Da diese Schmutztuchstücke eine im wesentlichen der Länge des gereinigten Zylinders 14 entsprechende Länge haben, können sie für einen anderen Zweck verwendet werden, insbesondere zur Reinigung von Farbwerken in Farbwerks-Reinigungsanlagen der Druckmaschine, bevor sie dann entsorgt werden. Die Schmutztuchstücke der Schmutztuchrolle 34 sind zwar verschmutzt, jedoch immer noch in der Lage, von Farbwerken Farbwerksreste und andere Schmutzpartikel aufzunehmen. Für das Aufschneiden des Schmutztuch-Wickels 37 auf der Schmutztuchrolle 34 braucht die dritte Lagervorrichtung 62 nicht so ausgebildet zu sein, daß die Wickelrolle 34 gedreht werden kann. Im Gegenteil, für das Aufschneiden des Schmutztuch-Wickels 64 ist es vorteilhafter, wenn die Schmutztuchrolle 34 nicht-rotierend fixiert wird. Eine solche Dreh-Blockierung kann mittels eines Sperrstiftes 72 gemacht werden, welcher durch eine Lagerhülse 74 hindurchgeführt ist und darin die in der Lagerhülse 74 drehbar gelagerte Schmutztuchrolle 34 blockiert.In the frame 4, cutting means, for example in the form of a rotating cutter disk 66 driven by an electric motor 67, are accommodated, which can be moved by motor along the dirty-cloth roller 34 by means of a transport device 68 in order to cut open the dirty-cloth roll 37 up to the dirty-cloth roll 34 in the axial longitudinal direction. Here, the knife disk 66 must be radially inserted close to the wipe roll 34 through the wipe roll 64 and must also be transported over the entire length of the wipe roll. This results in square pieces of dirty tissue, which have a length of the dirty tissue roll 37 and thus also a length corresponding essentially to the length of the cylinder 14. After the dirty tissue roll 37 has been axially cut open, these pieces of dirty tissue fall, either independently or by support by hand or mechanically, onto a collecting plate 70 arranged under the dirty tissue roller 34. Since these dirty tissue pieces have a length which essentially corresponds to the length of the cleaned cylinder 14, they can be used for another purpose, especially for cleaning inking units in inking unit cleaning systems of the printing press before they are then disposed of. The pieces of soiled cloth of the soiled roll 34 are soiled, but are still able to receive inking unit residues and other dirt particles from inking units. The third bearing device 62 need not be designed in such a way that the winding roll 34 can be rotated for the cutting of the dirty cloth roll 37 on the dirty cloth roll 34. On the contrary, for the cutting of the dirty tissue roll 64, it is more advantageous if the dirty tissue roll 34 is fixed in a non-rotating manner. Such a rotation lock can be made by means of a locking pin 72 which is supported by a bearing sleeve 74 is passed through and blocked in the bearing sleeve 74 rotatably mounted wipe roller 34.

Falls der Schmutztuch-Wickel 37 nicht in der vorstehend beschriebenen Weise in Längsrichtung aufgeschnitten werden soll, um 4-eckige Schmutztuchstücke zu bilden, besteht durch eine vierte Lagervorrichtung 76 die Möglichkeit, eine Sammelrolle 78 drehbar zu lagern, auf welche nacheinander die schmutzigen Waschtücher 37 von mehreren Schmutztuchrollen 34 aufgewickelt werden können. Die Sammelrolle 78 kann mittels einer Handkurbel 80 von Hand oder mittels eines Motors angetrieben werden. Die Sammelrolle 78 ist vorzugsweise so ausgebildet, daß auf sie eine gleiche Menge Waschtuch gewickelt werden kann wie auf die Vorratsrolle 10, so daß sich auf der Sammelrolle 78 ein Multi-Wickel 81 bildet, welcher aus einer Vielzahl von schmutzigen Waschtüchern 37 von einer entsprechenden Vielzahl von Schmutztuchrollen 34 besteht.If the dirty tissue wrap 37 is not to be cut open lengthwise in the manner described above, in order to form quadrangular pieces of dirty tissue, there is the possibility, by means of a fourth bearing device 76, of rotatably mounting a collecting roller 78 onto which the dirty wash towels 37 are successively disposed several rolls of dirty cloth 34 can be wound up. The collecting roller 78 can be driven by means of a hand crank 80 by hand or by means of a motor. The collecting roll 78 is preferably designed so that an equal amount of washcloth can be wound on it as on the supply roll 10, so that a multi-wrap 81 is formed on the collecting roll 78, which consists of a plurality of dirty washcloths 37 of a corresponding variety of dirty cloth rolls 34.

Die erste Lagervorrichtung 8 für die Vorratsrolle 10 und die vierte Lagervorrichtung 76 für die Sammelrolle 78 sind vorzugsweise im unteren Teil des Gestells 4 parallel nebeneinander angeordnet. Die zweite Lagervorrichtung 22 für die Saubertuchrolle 18 und die dritte Lagervorrichtung 62 für die Schmutztuchrolle 34 sind vorzugsweise im oberen Bereich des Gestells 4 parallel nebeneinander und parallel über den ersten und zweiten Lagervorrichtungen 8 und 76 angeordnet.The first bearing device 8 for the supply roll 10 and the fourth bearing device 76 for the collecting roll 78 are preferably arranged parallel to one another in the lower part of the frame 4. The second bearing device 22 for the cleaning cloth roll 18 and the third bearing device 62 for the dirty cloth roll 34 are preferably arranged in the upper region of the frame 4 in parallel next to one another and in parallel above the first and second bearing devices 8 and 76.

Bisher wurde für die Entsorgung von verschmutzten Waschtüchern nicht der Wickelstand verwendet. Bisher wurde die Schmutztuchrolle 34 mit dem verschmutzten Waschtuch 37 aus der Wascheinheit 30 herausgenommen und von Hand wurde das verschmutzte Waschtuch von der Schmutztuchrolle 34 abgewickelt. Dies ergab immer einen großen Berg von verknittert aufeinanderliegenden Waschtüchern auf dem Fußboden. Solche zerknitterten Waschtücher benötigen nicht nur viel Volumen für den Transport zu einer Entsorgungsstelle, sondern die Bedienungsperson und der Fußboden wurden von den verschmutzten Waschtüchern sehr schmutzig. Dabei wurde der Fußboden feucht und es bestand Rutschgefahr. Die Schmutztücher enthalten feuchte Druckfarben und andere, teilweise ölige Verunreinigungen. Durch vorliegende Erfindung wird eine Verschmutzung der Bedienungsperson und des Fußbodens vermieden und für die Entsorgung der verschmutzten Waschtücher wird wesentlich weniger Volumen benötigt. Die verschmutzten Waschtücher benötigen sowohl dann, wenn sie auf eine Sammelrolle 78 aufgewickelt werden, als auch dann, wenn sie im Wickelstand durch die Schneidmittel 66 von der Schmutztuchrolle 34 in Längsrichtung aufgeschnitten und dann aufgeklappt werden nur sehr wenig Volumen, da die einzelnen Waschtuchlagen unzerknittert kompakt aufeinanderliegen. Die Rollen 10, 18, 34 und 78 können hohl oder massiv sein.So far, the winding stand has not been used for the disposal of dirty washcloths. So far, the dirty towel roll 34 with the dirty wash towel 37 has been removed from the washing unit 30 and the dirty wash towel has been unwound from the dirty towel roll 34 by hand. This always resulted in a large mountain of crumpled washcloths on the floor. Such crumpled washcloths not only require a lot of volume for transportation to a disposal point, but the operator and the floor became very dirty from the soiled washcloths. The floor became damp and there was a risk of slipping. The dirty wipes contain damp printing inks and other, partly oily contaminants. Contamination of the operator and the floor is avoided by the present invention and much less volume is required for the disposal of the soiled washcloths. The soiled washcloths require very little volume both when they are wound onto a collecting roll 78 and when they are cut open in the winder stand by the cutting means 66 from the dirty cloth roll 34 in the longitudinal direction and then unfolded, since the individual washcloth layers are not wrinkled and compact lie on one another. The rollers 10, 18, 34 and 78 can be hollow or solid.

Am oberen Ende des Gestells 4 ist über der Schmutztuchrolle 34 eine Eichvorrichtung 82 zum Eichen von Wascheinheiten 30 vorgesehen. Die zu eichende Wascheinheit 30, welche in Fig. 1 durch strichpunktierte Linien schematisch dargestellt ist, wird in eine Aufnahmevorrichtung 84 der Eichvorrichtung 82 "eingesetzt", wobei die Aufnahmeöffnung 48 der Träger 46 auf Bolzen 40/2 gesteckt wird, welche am Gestell 4 auf beiden Stirnseiten ähnlich den Bolzen 40 der Seitenrahmen 42 der Druckmaschine vorgesehen sind. "Einsetzen" bedeutet hier einschieben, einhängen oder hinstellen derart, daß die Wascheinheit 30 vom Gestell 4 getragen wird und relativ zum Gestell 4 automatisch in eine vorbestimmte Position gebracht wird. Eine Anschlagwand 86 der Eichvorrichtung 82 ist anstelle des Zylinders 14 vorgesehen und bildet einen ersten Referenzpunkt. Die Bolzen 40/2 des Gestells 4 sind anstelle der Bolzen 40 der Seitenrahmen 42 vorgesehen und bilden einen zweiten Referenzpunkt. Die beiden Referenzpunkte 86 und 40/2 des Wickelstandes 2 von Fig. 1 haben den gleichen Abstand voneinander wie der Zylinder 14 von den Bolzen 40 der Druckmachinen-Seitenrahmen 42. Dadurch ist es möglich, eine Vielzahl von Wascheinheiten 30 einer Druckmaschine in der Eichvorrichtung 82 so zu eichen, daß beim Einbau in die Druckmaschine alle Wascheinheiten 30 den gleichen Anpreßdruck vom Andrückelement 32 auf einen Zylinder 14 erzeugen. Dadurch ist es möglich, die einzelnen Wascheinheiten 30 untereinander auszutauschen, ohne daß ein anderer als der vorbestimmte Anpreßdruck zwischen dem Andrückelement 32 und dem betreffenden Zylinder 14 erzeugt wird. Auch beim Austausch einer Wascheinheit 30 gegen eine Ersatz-Wascheinheit 30 wird durch eine Eichung in der Eichvorrichtung 82 sichergestellt, daß auch die Ersatz-Wascheinheit 30 den gleichen Anpreßdruck zwischen dem Andrückelement 32 unter dem betreffenden Zylinder 14 erzeugt. Diese Gleichheit des Anpreßdruckes für alle Wacheinheiten 30 ist unabhängig von Materialunterschieden der Andrückelemente 32 der verschiedenen Wascheinheiten 30 und unabhängig von Unterschieden in Herstellungstoleranzen zwischen verschiedenen Wascheinheiten 30. Bei der Erzeugung des Anpreßdruckes des Anpreßelementes 32 mittels Druckluft in der Druckluftkammer 36 wird erreicht, daß bei einem vorbestimmten Druck der Druckluft ein bestimmter, bei jeder Wascheinheit gleicher Anpreßdruck des Andrückelements 36 auf den Zylinder 34 erzeugt wird. Abweichend hiervon wurde beim Stand der Technik jede Wascheinheit erst in der Druckmaschine so eingestellt, daß sich für einen bestimmten das Andrückelement 32 expandierenden Luftdruck ein bestimmter Anpreßdruck des Andrückelements 32 am Zylinder 14 ergibt. Durch diese Einstellung jeder Wascheinheit 30 auf den ihr zugeordneten Zylinder 14 war es bisher nicht möglich, die Wascheinheiten verschiedener Zylinder gegenseitig auszutauschen, ohne die Wascheinheiten 30 relativ zu jedem Zylinder neu zu justieren.At the upper end of the frame 4, a calibration device 82 for calibrating washing units 30 is provided above the dirty cloth roll 34. The washing unit 30 to be calibrated, which is shown schematically in FIG. 1 by dash-dotted lines, is “inserted” into a receiving device 84 of the calibrating device 82, the receiving opening 48 of the carrier 46 being plugged onto bolts 40/2, which are on the frame 4 two end faces similar to the bolts 40 of the side frame 42 of the printing press are provided. "Insert" here means pushing in, hanging in or putting down in such a way that the washing unit 30 is carried by the frame 4 and is automatically brought into a predetermined position relative to the frame 4. A stop wall 86 of the calibration device 82 is provided instead of the cylinder 14 and forms a first reference point. The Bolts 40/2 of the frame 4 are provided instead of the bolts 40 of the side frame 42 and form a second reference point. The two reference points 86 and 40/2 of the winding stand 2 from FIG. 1 are at the same distance from one another as the cylinder 14 from the bolts 40 of the printing machine side frames 42. This makes it possible to have a large number of washing units 30 of a printing press in the calibration device 82 To calibrate so that when installed in the printing press, all washing units 30 generate the same contact pressure from the pressing element 32 on a cylinder 14. This makes it possible to exchange the individual washing units 30 with one another without generating a pressure other than the predetermined contact pressure between the pressing element 32 and the relevant cylinder 14. Even when a washing unit 30 is replaced by a replacement washing unit 30, calibration in the calibration device 82 ensures that the replacement washing unit 30 also generates the same contact pressure between the pressing element 32 under the relevant cylinder 14. This equality of the contact pressure for all waxing units 30 is independent of the material differences of the pressing elements 32 of the different washing units 30 and independent of differences in manufacturing tolerances between different washing units 30. When the contact pressure 32 is generated by means of compressed air in the compressed air chamber 36, the contact pressure 32 achieves that at one predetermined pressure of the compressed air, a certain contact pressure of the pressing element 36 on the cylinder 34 which is the same for each washing unit is generated. Deviating from this, each washing unit in the prior art was first set in the printing press in such a way that for a specific air pressure expanding the pressure element 32, a specific contact pressure of the pressure element 32 on the cylinder 14 results. This setting of each washing unit 30 to the cylinder 14 assigned to it has not previously been the case possible to exchange the washing units of different cylinders with one another without having to readjust the washing units 30 relative to each cylinder.

Der vom Andrückelement 32 auf den Zylinder 14 ausgeübte Anpreßdruck wurde bisher mit viel Zeitaufwand dadurch gemessen, daß zwischen das Andrückelement 32 und den Zylinder 14 eine Meßplatte gelegt wurde und diese Meßplatte dann mit einem Zugmeßgerät aus dem Spalt zwischen dem Andrückelement 32 und dem Zylinder 14 herausgezogen wurde. Der Zugmeßwert war ein Maß für den Anpreßdruck. Diese Meßart kann selbstverständlich auch bei der Eichvorrichtung 82 verwendet werden. Wesentlich einfacher ist die Messung jedoch dann, wenn der erste Referenzpunkt 86 mit einer Druckmeßeinrichtung versehen wird, welche den Druck direkt der Bedienungsperson anzeigt. Vorzugsweise sind mit axialem Abstand voneinander mindestens zwei Druckmeßgeräte 88 und 90 vorgesehen. Durch die Verwendung von mindestens zwei mit axialem Abstand voneinander angeordneten Druckmeßgeräten 88 und 90 ist es möglich, sofort zu erkennen, ob der Anpreßdruck des Andrückelementes 32 über die gesamte Länge des Zylinders 14 gleichmäßig oder unterschiedlich ist, so daß eine entsprechende Druckkorrektur vorgenommen werden kann.The contact pressure exerted by the pressing element 32 on the cylinder 14 has so far been measured with a great deal of time in that a measuring plate was placed between the pressing element 32 and the cylinder 14 and this measuring plate was then pulled out of the gap between the pressing element 32 and the cylinder 14 using a tension measuring device has been. The tensile measurement was a measure of the contact pressure. This type of measurement can of course also be used with the calibration device 82. However, the measurement is much simpler if the first reference point 86 is provided with a pressure measuring device which indicates the pressure directly to the operator. At least two pressure gauges 88 and 90 are preferably provided at an axial distance from one another. By using at least two axially spaced pressure measuring devices 88 and 90, it is possible to immediately recognize whether the contact pressure of the pressing element 32 is uniform or different over the entire length of the cylinder 14, so that a corresponding pressure correction can be carried out.

In bevorzugter Ausführungsform wird das Andrückelement 32 durch den in einer Druckkammer 36 erzeugten Luftdruck gegen den Zylinder 14 gepreßt. Die dazu erforderliche Druckluft ist auch in der Eichvorrichtung 82 erforderlich, weshalb der Wickelstand 2 mit einem am Gestell 4 befestigten zweiten Druckluftanschluß 92 versehen ist. Der erste Druckluftanschluß 60 der Wascheinheit 30 wird am zweiten Druckluftanschluß 92 des Wickelstandes 2 angeschlossen, und der letztere 92 ist an eine Druckluftquelle 94 anschließbar.In a preferred embodiment, the pressure element 32 is pressed against the cylinder 14 by the air pressure generated in a pressure chamber 36. The compressed air required for this is also required in the calibration device 82, which is why the winding station 2 is provided with a second compressed air connection 92 attached to the frame 4. The first compressed air connection 60 of the washing unit 30 is connected to the second compressed air connection 92 of the winding station 2, and the latter 92 can be connected to a compressed air source 94.

Bei der in Fig. 4 gezeigten Anwendung des Wickelstandes 2 ist in ihn eine Wascheinheit 30/2 eingesetzt, welche kürzer ist als die Wascheinheit 30 von Fig. 1. Zur Überbrückung des sich dabei ergebenden Abstandes zu den an beiden Stirnseiten des Wickelstandes 2 vorgesehenen Bolzen 40/2, welche den zweiten Referenzpunkt bilden, ist ein Adapter 96 vorgesehen. Der Adapter 96 wird durch den Bolzen 40/2 positioniert und ist mit einem Bolzen 40/3 versehen, welcher in die Aufnahmeöffnng 48 der Träger 46 eingreift und die Wascheinheit 30/2 an ihrer Anschlagfläche 44 mit Bezug auf die Anschlagwand 86 positioniert.In the application of the winding stand 2 shown in FIG. 4, a washing unit 30/2 is inserted into it, which is shorter than the washing unit 30 of FIG. 1. To bridge the resulting distance from the bolts provided on both ends of the winding stand 2 40/2, which form the second reference point, an adapter 96 is provided. The adapter 96 is positioned by the bolt 40/2 and is provided with a bolt 40/3, which engages in the receiving opening 48 of the carrier 46 and positions the washing unit 30/2 on its stop surface 44 with reference to the stop wall 86.
