Description

Die vorstehende Erfindung betrifft einen einstellbaren Aufnahmewagen für einen Druckzylinder.The above invention relates to an adjustable receiving carriage for a printing cylinder.

Es ist bekannt, dass in Rotationsdruckmaschinen Druckzylinder zum Einsatz kommen, die unter Verwendung geeigneter Aufnahmewagen, die auf Gleisen verschiebbar angeordnet sind, in das Druckwerk der Rotationsdruckmaschine eingefahren werden. Hierzu weist die Oberseite der bekannten Aufnahmewagen für Druckzylinder U-förmige Gestalt auf und an den oberen Enden der parallel angeordneten Arme der U-förmigen Vorrichtungen, sind Lager zur Aufnahme der Endzapfen des Druckzylinders vorgesehen. Einer der Endzapfen des Druckzylinders ist mit einem Antriebsmittel bestückt, z. B. einem Zahnrad, das mit einem entsprechenden Antriebsrad des Hauptantriebes der Druckmaschine verbindbar ist. Die bekannten Aufnahmewagen haben sich seit langer Zeit als durchaus tauglich erwiesen, da durch ihren Einsatz ein schnelles Austauschen des Druckzylinders in der Rotationsdruckmaschine ermöglicht wird. In der Druckmaschine treten aber erhebliche maschinenbautechnische Probleme auf, wenn die nutzbare Länge des Druckzylinders verändert werden muss, d. h. wenn ein Druckzylinder mit einer bestimmten Länge durch einen kürzeren oder längeren Druckzylinder in der Maschine ersetzt werden soll. In diesem Falle ist es unumgänglich, den Druckzylinder mit den entsprechenden Lagern auszubauen. Auf die Endzapfen des kürzeren Druckzylinders werden hochpräzise Verlängerungs- und Lagerhülsen aufgesteckt, die von den Lagern des Wagens aufgenommen werden. Im Anschluss daran, wird der so vorbereitete kürzere Druckzylinder erneut in die Maschine eingefahren. Es ist für einen Fachmann einleuchtend, dass einmal die Montage der Verlängerungshülsen auf den Zapfen der kürzeren Druckzylinder einen erheblichen maschinenbaulichen Aufwand mit sich bringt, besonders wenn man berücksichtigt, dass die Druckzylinder höchster Präzision drehen müssen. Daraus folgt, dass die Verlängerungshülsen äusserst präzise bearbeitet werden müssen und diese Bearbeitung einen erheblichen Kostenfaktor darstellt. Hierbei ist zu berücksichtigen, dass für alle Druckzylinder aufgrund ihrer unterschiedlichen Längenabmessungen, mehrere verschieden lange Verlängerungshülsen bereitstehen.It is known that printing cylinders are used in rotary printing presses which are moved into the printing unit of the rotary printing press using suitable receiving carriages which are arranged displaceably on tracks. For this purpose, the top of the known receiving carriages for printing cylinders has a U-shaped configuration and at the upper ends of the parallel arms of the U-shaped devices, bearings are provided for receiving the end journals of the printing cylinder. One of the end journals of the impression cylinder is equipped with a drive means, e.g. B. a gear that can be connected to a corresponding drive wheel of the main drive of the printing press. The known pick-up carriages have proven to be quite suitable for a long time, since their use enables the printing cylinder to be exchanged quickly in the rotary printing press. However, considerable mechanical engineering problems arise in the printing press if the usable length of the printing cylinder has to be changed, i. H. if a printing cylinder with a certain length is to be replaced by a shorter or longer printing cylinder in the machine. In this case, it is essential to remove the pressure cylinder with the appropriate bearings. High-precision extension and bearing sleeves are plugged onto the end journals of the shorter pressure cylinder and are taken up by the bearings of the carriage. Subsequently, the shorter pressure cylinder prepared in this way is retracted into the machine. It is obvious to a person skilled in the art that once the extension sleeves are mounted on the pins of the shorter printing cylinders, this entails a considerable amount of mechanical engineering work, especially when one takes into account that the printing cylinders have to rotate with the highest precision. It follows that the extension sleeves have to be machined extremely precisely and this machining represents a considerable cost factor. It must be taken into account here that several different length extension sleeves are available for all printing cylinders due to their different length dimensions.

Es ist weiterhin zu berücksichtigen, dass, auch wenn die Verlängerungs- und Lagerhülsen hochpräzise bearbeitet sind, die Steifigkeit eines solchen Zylinders erheblich abnimmt, je mehr die Länge des verwendeten Druckzylinders gegenüber der Breite der Rotationsdruckmaschine abnimmt.It should also be taken into account that, even if the extension and bearing sleeves are machined with high precision, the stiffness of such a cylinder decreases considerably, the more the length of the printing cylinder used decreases in relation to the width of the rotary printing press.

Aus der US-A-3 625145 ist ein bekannter Aufnahmewagen für einen Druckzylinder beschrieben, der als vollständige Druckeinheit ausgebildet ist. Neben einem kompletten Farbwerk weist der Wagen auch eine Rakelvorrichtung für den Druckzylinder auf.From US-A-3 625145 a known receiving carriage for a printing cylinder is described, which is designed as a complete printing unit. In addition to a complete inking unit, the carriage also has a squeegee device for the printing cylinder.

Da die bekannte Vorrichtung als vollständige, eigenständige Druckeinheit ausgebildet ist, die während des Betriebs der Druckmaschine in diese eingefahren wird und in der Maschine verbleibt, ist sie nicht geeignet, austauschbare Druckzylinder mit unterschiedlicher Länge, unter Verwendung eines einfachen Aufnahmewagens und unter Vorsehung verschiebbarer Lagerungen in die Druckmaschine zu Montagezwecken einzufahren oder zu entnehmen.Since the known device is designed as a complete, independent printing unit, which is retracted into the printing press during operation and remains in the press, it is not suitable for replaceable printing cylinders of different lengths, using a simple pick-up carriage and with provision for displaceable bearings in retract or remove the press for assembly purposes.

Dies ist auch nicht Aufgabe des bekannten Wagens, der dazu dient, ein vollständiges Druckwerk in eine Rotationsmaschine einzufahren. Bei der bekannten Vorrichtung verbleibt der Wagen während des gesamten Druckvorganges in der Maschine.This is also not the task of the known carriage, which is used to drive a complete printing unit into a rotary machine. In the known device, the carriage remains in the machine during the entire printing process.

Aufgabe der vorstehenden Erfindung ist es, einen neuen Aufnahmewagen für einen Druckzylinder der beschriebenen Art zu schaffen, der bei einer Rotationsdruckmaschine in Verwendung kommt und der es ermöglicht, Druckzylinder mit unterschiedlichen Längen zu verwenden ohne die Notwendigkeit, den Druckzylinder mit Verlängerungs- und Aufnahmehülsen zu bestücken. Es soll ferner ein rascher Austausch der Druckzylinder ohne grossen Montageaufwand sowie eine direkte Lagerung der Druckzylinder, unabhängig von ihrer Länge, möglich sein.The object of the above invention is to provide a new receiving carriage for a printing cylinder of the type described, which is used in a rotary printing press and which enables printing cylinders of different lengths to be used without the need to equip the printing cylinder with extension and receiving sleeves . It should also be possible to quickly replace the printing cylinders without great assembly effort and to store the printing cylinders directly, regardless of their length.

Die erfindungsgemässe Aufgabe wird dadurch gelöst, dass parallel zur Längsachse des Druckzylinders 16 Gleitführungen 9 vorgesehen sind, die darauf verschiebbare Aufnahmevorrichtungen 10, 11 für die Lagerung 12-15 der Endzapfen 17, 18 des Druckzylinders 16 tragen.The object according to the invention is achieved in that slide guides 9 are provided parallel to the longitudinal axis of the printing cylinder 16, and carry sliding devices 10, 11 thereon for the mounting 12-15 of the end journals 17, 18 of the printing cylinder 16.

Wünschenswert ist es ferner, die Möglichkeit zu schaffen, eine rasche und beliebige Lagereinstellung des Druckzylinders, sowie eine einfache Verbindung mit den Antriebsmitteln der Maschine unter Einsatz einfacher und billiger Bauteile und unter Einsatz eines baulich sehr einfachen Wagens zu ermöglichen.It is also desirable to be able to quickly and arbitrarily adjust the position of the printing cylinder, as well as a simple connection to the drive means of the machine using simple and inexpensive components and using a structurally very simple carriage.

Weitere Vorteile und Merkmale können der nun folgenden Beschreibung, den Unteransprüchen und den beigefügten Zeichnungen entnommen werden.Further advantages and features can be found in the following description, the subclaims and the accompanying drawings.

In vorteilhafter Weise nehmen die Endzapfen der Druckzylinder eine Verlängerungshülse auf, die lediglich zur Aufnahme von Verbindungsmitteln vorgesehen ist, jedoch keine Lager- und Stützfunktion erfüllt, sondern lediglich zum Einstellen und Positionieren des Druckzylinders im Inneren der Maschine, sowie für die Verbindung des Zylinders mit einer Antriebsvorrichtung, die Bestandteil des zentralen Antriebssystems der Maschine ist, vorgesehen ist.Advantageously, the end journals of the printing cylinders receive an extension sleeve, which is provided only for receiving connecting means, but does not have a storage and support function, but only for adjusting and positioning the printing cylinder inside the machine, and for connecting the cylinder to one Drive device, which is part of the central drive system of the machine, is provided.

Die erfindungsgemässe Vorrichtung wird nun anhand eines Ausführungsbeispieles genauer beschrieben und in der einzigen Zeichnung dargestellt, in der der erfindungsgemässe Aufnahmewagen für die Lagerung des Druckzylinders teilweise in Ansicht und teilweise im Schnitt dargestellt ist.The device according to the invention will now be described in more detail using an exemplary embodiment and shown in the single drawing, in which the receiving carriage according to the invention for mounting the printing cylinder is shown partly in view and partly in section.

Wie der Figur zu entnehmen ist, besteht der gesamthaft mit 1 gekennzeichnete Wagen aus einem Rahmen 2, der mittels Laufrädern 3 und 4 auf Gleisen 5 verfahrbar ist, die senkrecht zu den Seitenwagen 6 und 7 der Maschine ausgerichtet sind. In Übereinstimmung mit den Gleisen 5, weist die Wange 7 eine Ausnehmung zum Einführen des Wagens 1 in die Maschine auf, wogegen die gegenüberliegende Wange 6 der Druckmaschine eine Öffnung 8 aufweist, zum Durchführen des verlängerten Verbindungsstückes 19, das im Anschluss noch genauer beschrieben wird.As can be seen from the figure, the carriage, identified as a whole by 1, consists of a frame 2 which is supported by wheels 3 and 4 Tracks 5 is movable, which are aligned perpendicular to the side car 6 and 7 of the machine. In accordance with the tracks 5, the cheek 7 has a recess for the insertion of the carriage 1 into the machine, whereas the opposite cheek 6 of the printing machine has an opening 8 for the passage of the extended connecting piece 19, which will be described in more detail below.

An seiner Oberseite weist der Wagen 1 parallele Gleitführungen 9 auf, wie diese z.B. aus dem Werkzeugmaschinenbau her bekannt sind. Diese Gleitführungen nehmen verschiebbar Aufnahmevorrichtungen 10 und 11 auf, die in Richtung des Pfeiles f längs der parallelen Gleitführungen 9 bewegbar sind. Jede Aufnahmevorrichtung 10, 11 nimmt einen bekannten Lagerbock 12 bzw. 13 auf, der ein Kugellager 14 bzw. 15 aufnimmt.On its upper side, the carriage 1 has parallel sliding guides 9, such as these e.g. are known from machine tool manufacturing. These sliding guides slidably receive receiving devices 10 and 11 which can be moved in the direction of arrow f along the parallel sliding guides 9. Each receiving device 10, 11 receives a known bearing block 12 or 13, which receives a ball bearing 14 or 15.

Jeder Druckzylinder 16 weist einen Endzapfen 17 bzw. 18 auf, dessen Verlängerung 17a bzw. 18a vom Laufring 14 bzw. 15 des Kugellagers aufgenommen werden.Each pressure cylinder 16 has an end pin 17 or 18, the extension 17a or 18a of which is received by the race 14 or 15 of the ball bearing.

Jede Verlängerung 17a bzw. 18a weist ferner eine weitere zapfenartige Verlängerung 17b bzw. 18b auf, die eine Verlängerungshülse 19 bzw. 20 aufnimmt, die fest mit dem Zapfen 17b, 18b verbunden ist. Zu diesem Zweck findet eine Schraube 21 bzw. 22 Verwendung.Each extension 17a or 18a also has a further pin-like extension 17b or 18b which receives an extension sleeve 19 or 20 which is fixedly connected to the pin 17b, 18b. A screw 21 or 22 is used for this purpose.

Die Verlängerungen 19 und 20 haben keinerlei Lager- und Stützfunktion zu erfüllen und werden im Anschluss noch genauer beschrieben.The extensions 19 and 20 do not have any storage and support functions and are described in more detail below.

Die Lagerböcke 12 bzw. 13, zusammen mit den Aufnahmevorrichtungen 10 und 11 können entlang der Gleitführungen 9 in Richtung des Pfeiles f verschoben werden und ermöglichen somit ein Anpassen an die sich ändernde Länge I der Druckzylinder 16, sowie ein beliebiges Positionieren des Druckzylinders 16 auf dem Wagen 1 und somit in der Druckmaschine. Ferner können die Lagerböcke 12 bzw. 13 eine schematisch durch Strichpunktlinien angedeutete, nach unten gerichtete Verlängerungskonsole 23 und 24 aufweisen. Jede nach unten gerichtete Verlängerungskonsole 23, 24 steht mit einer Gewindespindel 25 bzw. 26 in Wirkverbindung, von denen jede in Richtung des Pfeiles g antreibbar ist. Jede Gewindespindel 25 bzw. 26 steht zu diesem Zweck in bekannter, nicht dargestellter Weise, mit einem Handrad in Wirkverbindung, über welches bei Drehbewegung ein Verschieben der Aufnahmevorrichtungen 10 und 11, sowie der Lagerböcke 12 bzw. 13 erfolgt. Somit können diese Bauteile entlang der parallelen Gleitführungen 9 in der gewünschten Lage positioniert werden. In naheliegender Weise kann jede Aufnahmevorrichtung fest auf den Gleitführungen 9, z. B. unter Verwendung von Spannschrauben oder ähnlichen Hilfsmitteln, wie Spannklauen, festgespannt werden.The bearing blocks 12 and 13, together with the receiving devices 10 and 11 can be moved along the slide guides 9 in the direction of arrow f and thus allow adaptation to the changing length I of the printing cylinder 16, as well as any positioning of the printing cylinder 16 on the Carriage 1 and thus in the printing press. Furthermore, the bearing blocks 12 and 13 can have an extension bracket 23 and 24, which is indicated schematically by broken lines and points downward. Each downward extension bracket 23, 24 is operatively connected to a threaded spindle 25 or 26, each of which can be driven in the direction of arrow g. For this purpose, each threaded spindle 25 or 26 is operatively connected in a known manner, not shown, to a handwheel, via which the receiving devices 10 and 11 and the bearing blocks 12 and 13 are displaced when the rotary movement occurs. These components can thus be positioned in the desired position along the parallel sliding guides 9. In an obvious manner, each receiving device can be fixed on the slide guides 9, z. B. using clamping screws or similar tools, such as clamping claws.

Wie bereits vorher beschrieben, ist sowohl die Verlängerung 17b des Endzapfens 17, als auch die Verlängerung 18b des Endzapfens 18 des Druckzylinders 16 mit Verlängerungshülsen 19 und 20 bestückt. Wie der Zeichnung deutlich zu entnehmen ist, haben die Verlängerungshülsen 19 und 20 aber keinerlei Stütz- oder Lagerfunktion. Die auf / der linken Seite der Zeichnung dargestellte Verlängerung 19 nimmt an ihrem Ende ein Zahnrad 27 auf, das z.B. mit einem weiteren Zahnrad 28 in Wirkverbindung gebracht wird. Das Zahnrad 28 wird über das zentrale Antriebssystem der Druckmaschine angetrieben und versetzt somit den Druckzylinder, 16 in Drehbewegung. Zu diesem Zweck ist die Verlängerung 19 fest mit der Verlängerung 17b des Endzapfens 17, z.B. unter Zuhilfenahme einer durchgehenden Spannschraube 21 verbunden und zwischen dem Verlängerungsstück 17b des Endzapfens 17 und dem Ende der Verlängerungshülse 19 ist ein Verbindungskeil 29 eingesetzt.As already described above, both the extension 17b of the end pin 17 and the extension 18b of the end pin 18 of the pressure cylinder 16 are equipped with extension sleeves 19 and 20. As can be clearly seen in the drawing, the extension sleeves 19 and 20 have no support or bearing function. The extension 19 shown on the left side of the drawing receives at its end a gear 27 which e.g. is brought into operative connection with a further gear wheel 28. The gear 28 is driven by the central drive system of the printing press and thus sets the printing cylinder 16 in rotary motion. For this purpose the extension 19 is fixed to the extension 17b of the end pin 17, e.g. connected with the aid of a continuous clamping screw 21 and a connecting wedge 29 is inserted between the extension piece 17b of the end pin 17 and the end of the extension sleeve 19.

Auch die Verlängerung 18b des Endzapfens 18 ist mit einer nicht tragenden Verlängerungshülse 20 verbunden und auch in diesem Falle findet für die feste Verbindung mit dem Endzapfen 18 eine Schraube und ein Keil 30 Verwendung. Das freie Ende der Verlängerungshülse 20 ist mit einer Drehvorrichtung 31 wirkverbunden. Diese Drehvorrichtung 31 hat die Aufgabe, den Druckzylinder 16 in seiner Winkelstellung zu positionieren, um zu gewährleisten, dass über gesamte Länge der Druckmaschine sämtliche Druckzylinder einwandfrei untereinander ausgerichtet sind (Register).The extension 18b of the end pin 18 is also connected to a non-load-bearing extension sleeve 20 and also in this case a screw and a wedge 30 are used for the fixed connection to the end pin 18. The free end of the extension sleeve 20 is operatively connected to a rotating device 31. This rotating device 31 has the task of positioning the printing cylinder 16 in its angular position in order to ensure that all printing cylinders are perfectly aligned with one another over the entire length of the printing press (register).

Wie der beigefügten Zeichnung zu entnehmen ist, wird der Druckzylinder 16 in unmittelbarer Nähe seiner Endzapfen gelagert, und somit ist das entstehende Biegemoment wesentlich kleiner als im Falle der bisher bekanntgewordenen Aufnahme- und Lagervorrichtungen, die bisher an den Stirnenden der bekannten Aufnahmewagen vorgesehen waren. Entsprechend der vorstehenden Erfindung kann der Druckzylinder 16 beliebig auf den Gleitführungen 9 des Wagens 1 verschoben und positioniert werden und der Austausch eines Druckzylinders 16 mit einem Druckzylinder, der andere Längenabmessungen I aufweist, erfolgt schnell und ohne die Notwendigkeit, aufwendige und zeitraubende Montagearbeiten durchzuführen.As can be seen from the accompanying drawing, the pressure cylinder 16 is mounted in the immediate vicinity of its end journals, and thus the resulting bending moment is considerably smaller than in the case of the previously known receiving and storage devices which were previously provided on the ends of the known receiving carriages. According to the above invention, the pressure cylinder 16 can be moved and positioned as desired on the slide guides 9 of the carriage 1 and the exchange of a pressure cylinder 16 with a pressure cylinder which has other length dimensions I takes place quickly and without the need to carry out complex and time-consuming assembly work.

Somit wird der Wirkungsgrad der Druckmaschine erheblich verbessert. Ferner erfordert die Bearbeitung der Verlängerungshülse 19 und 20 einen wesentlich geringeren Aufwand, da diese Bauteile keinerlei Lagerfunktion zu erfüllen haben, sondern lediglich für die Übertragung der Drehbewegung an den Druckzylinder 16, sowie für die Quereinstellung vorgesehen sind.This significantly improves the efficiency of the printing press. Furthermore, the processing of the extension sleeve 19 and 20 requires considerably less effort, since these components have no bearing function to fulfill, but are only provided for the transmission of the rotary movement to the pressure cylinder 16 and for the transverse adjustment.
