Description

Die vorstehende Erfindung betrifft einen einstellbaren Aufnahmewagen fuer einen Druckzylinder. Es ist bekannt, dass in Rotationsdruckmaschi-nen 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 Aufnahemwagen fuer Druckzylinder U-foermige Gestalt auf und an den oberen Enden der parallel angeordneten Arme der U-foermigen Vorrichtungen, sind Lager zur Aufnahme der Endzapfen des Druckzylinders vorgesehen. Einer der Endzapfen des Druckzylinders ist mit einem Antriebsmittel bestueckt, 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 ermoeglicht wird. In der Druckmaschine treten aber erhebliche maschinenbautechnische Probleme auf, wenn die nutzbare Laenge des Druckzylinders veraendert werden muss, d.h. wenn ein Druckzylinder mit einer bestimmten Laenge durch einen kuerzerenoder laengeren Druckzylinder in der Maschine ersetzt werden soll. In diesem Falle ist es unumgaenglich, den Druckzylinder mit den entsprechenden Lagern auszubauen. Auf die Endzapfen des kuerzeren Druckzylinders werden hochpraezise Verlaengerungs- und Lagerhuelsen aufgesteckt, die von den Lagern des Wagens aufgenommen werden. Im Anschluss daran, wird der so vorbereitete kuerzere Druckzylinder erneut in die Maschine eingefahren. Es ist fuer einen Fachman einleuchtend, dass einmal die Montage der Verlaengerungshuelsen auf den Zapfen der kuerzeren Druckzylinder einen erheblichen maschinenbaulichen Aufwand mit sich bringt, besonders wenn man beruecksichtigt, dass die Druckzylinder hoechster Praezision drehen muessen. Daraus folgt, dass die Verlaengerungshuelsen aeusserst praezise bearbeitet werden muessen und diese Bearbeitung einen erheblichen Kostenfaktor darstellt. Hierbei ist zu beruecksichtigen, dass fuer alle Druckzylinder aufgrund ihrer unterschiedlichen Laengenabmessungen, mehrere verschiedenlange i Verlaengerungshuelsen bereitstellen.The above invention relates to an adjustable receiving carriage for a printing cylinder. 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 carriage for printing cylinders has a U-shaped configuration and bearings for receiving the end journals of the printing cylinder are provided at the upper ends of the arms of the U-shaped devices arranged in parallel. One of the end journals of the pressure cylinder is equipped with a drive means, for example a gearwheel, which is connected to a corresponding drive wheel of the Main drive of the printing press is connectable. 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, ie if a printing cylinder with a specific length is to be replaced by a shorter or longer printing cylinder in the press. In this case it is essential to remove the pressure cylinder with the appropriate bearings. High-precision extension and bearing sleeves are attached to 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 specialist that the assembly of the extension sleeves on the journals of the shorter pressure cylinders involves considerable mechanical engineering work, especially when one takes into account that the pressure cylinders have to turn with the highest precision. It follows that the extension sleeves have to be processed very precisely and this processing represents a considerable cost factor. It should be taken into account here that, due to their different length dimensions, all printing cylinders provide several different lengths of extension sleeves.

Es ist weiterhin zu beruecksichtigen, dass, auch wenn die Verlaengerungs- und Lagerhuelsen hochpraezise bearbeitet sind, die Steifigkeit eines solchen Zylinders erheblich abnimmt, je mehr die Laenge des verwendeten Druckzylinders gegenueber der Breite der Rotationsdruckmaschine abnimmt.It must also be taken into account that, even if the extension and bearing sleeves are machined very precisely, the stiffness of such a cylinder decreases considerably the more the length of the printing cylinder used decreases compared to the width of the rotary printing press.

Aufgabe der vorstehenden Erfindung ist es, einen neuen Aufnahmewagen fuer einen Druckzylinder der beschriebenen Art zu schaffen, der hauptsaechlich mit einer Rotationsdruckmaschine in Verwendung kommt, der es ermoeglicht, Druckzylinder mit unterschiedlichen Laengen zu verwenden, ohne die Notwendigkeit, den Druckzylinder mit Verlaengerungs- und Aufnahmehuelsen zu bestuecken. Es soll ferner ein rascher Austausch der Druckzylinder ohne grossen Montageaufwand, sowie eine direkte Lagerung der Druckzylinder, unabhaengig von ihrer Laenge moeglich sein. Ferner soll die Moeglichkeit einer raschen und beliebigen Lageeinstellung 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, moeglich sein.The object of the above invention is to create a new receiving carriage for a printing cylinder of the type described, which mainly comes into use with a rotary printing machine, which makes it possible to use printing cylinders of different lengths, without the need to use the printing cylinder with extension and receiving sleeves to equip. 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. Furthermore, the possibility of a quick and arbitrary position adjustment 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, should be possible.

Die erfindungsgemaesse Aufgabe wird dadurch geloest, dass der Aufnahmewagen parallel zur Laengsachse des Druckzylinders ausgerichtete Gleitfuehrungen aufweist, die verschiebbar Aufnahmevorrichtungen fuer die Lager, sowie die Endzapfen des Druckzylinders aufnehmen.The object according to the invention is achieved in that the receiving carriage has sliding guides oriented parallel to the longitudinal axis of the printing cylinder, which slide receptacles for the bearings and the end pins of the printing cylinder.

In vorteilhafter Weise nehmen die Endzapfen der Druckzylinder eine Verlaengerungsbuechse auf, die lediglich zur Aufnhame von Verbindungsmitteln vorgesehen ist, jedoch keine Lager- und Stuetzfunktion erfuellt, sondern lediglich zum Einstellen und Positionieren des Druckzylinders im Inneren der Maschine, sowie fuer die Verbindung des Zylinders mit einer Antriebsvorrichtung, die Bestandteil des zentralen Antriebssystems der Maschine ist, vorgesehen ist.The end journals of the pressure cylinders advantageously take one Extension sleeve, which is only intended to receive connecting means, but does not perform a storage and support function, but only for adjusting and positioning the pressure cylinder inside the machine, as well as for connecting the cylinder to a drive device, which is part of the central drive system of the machine is provided.

Weitere Vorteile und Merkmale der Erfindung koennen der nun folgenden Beschreibung, den Unteranspruechen und der beigefuegten Zeichnung entnommen werden.Further advantages and features of the invention can be found in the following description, the subclaims and the accompanying drawing.

Die erfindungsgemaesse Vorrichtung wird nun anhand eines Ausfuehrungsbeispieles genauer beschrieben und in der einzigen Zeichnung dargestellt, in der der erfindungsgemaesse Aufnahmewagen fuer die Lagerung des Druckzylinders teilweise in Ansicht und teilweise im Schnitt darstellt 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 the mounting of 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 Laufraedern 3 und 4 auf Gleisen 5 verfahrbar ist, die senkrecht zu den Seitenwangen 6 und 7 der Maschine ausgerichtet sind. In Uebereinstimmung mit den Gleisen 5, weist die Wange 7 eine Ausnehmung zum Einfuehren des Wagens 1 in die Maschine auf, wogegen die gegenueberliegende Wange 6 der Druckmaschine eine Oeffnung 8 aufweist, zum Durchfuehren des verlaengerten Verbindungsstueckes 19, das im Anschluss noch genauer beschrieben wird.As can be seen from the figure, the carriage, identified overall by 1, consists of a frame 2 which can be moved by means of running wheels 3 and 4 on rails 5 which are aligned perpendicular to the side walls 6 and 7 of the machine. In accordance with the tracks 5, the cheek 7 has a recess for inserting the carriage 1 into the machine, whereas the opposite cheek 6 of the printing machine has an opening 8 for carrying out the extended connecting piece 19, which will be described in more detail below.

An seiner Oberseite weist der Wagen 1 parallele Geitfuehrungen 9 auf, wie diese z.B. aus dem Werkzeugmaschinenbau her bekannt sind. Diese Gleitfuehrungen nehmen verschiebbar Aufnahmevorrichtungen 10 und 11 auf, die in Richtung des Pfeiles f laengs der parallelen Geitfuehrungen 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 those e.g. are known from machine tool manufacturing. These sliding guides slidably accommodate receiving devices 10 and 11 which can be moved in the direction of the 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 Verlaengerung 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 Verlaengerung 17a bzw. 18a weist ferner eine weitere zapfenartige Verlaengerung 17b bzw 18b auf, die eine Verlaengerungshuelse 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 a lengthening sleeve 19 or 20 which is fixedly connected to the pin 17b, 18b. A screw 21 or 22 is used for this purpose.

Die Verlaengerungen 19 und 20 haben keinerlei Lager- und Stuetzfunktion zu erfuellen und werden im Anschluss noch genauer beschrieben.The extensions 19 and 20 have no storage and support functions to be performed and are described in more detail below.

Die Lagerboecke 12 bzw. 13, zusammen mit den Aufnahmevorrichtungen 10 und 11 koennen entlang der Gleitfuehrungen 9 in Richtung des Pfeiles f verschoben werden und ermoeglichen somit ein Anpassen an die sich aendernde Laenge (I) der Druckzylinder 16, sowie ein beliebiges Positionieren des Druckzylinders 16 auf dem Wagen 1 und somit in der Druckmaschine. Ferner koennen die Lagerboecke 12 bzw. 13 eine schematisch durch Strichpunktlinien angedeutete, nach unten gerichtete Verlaengerungskonsole 23 und 24 aufweisen. Jede nach unten gerichtete Veraengerungskonsote 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, ueber welches bei Drehbewegung ein Verschieben der Aufnahmevorrichtungen 10 und 11, sowie der Lagerboecke 12 bzw. 13 erfolgt. Somit koennen diese Bauteile entlang der parallelen Geitfuehrungen 9 in der gewuenschten Lage positioniert werden. In naheliegender Weise kann jede Aufnahmevorrichtung fest auf den Gleifuehrungen 9, z.B. unter Verwendung von Spannschrauben oder aehnlichen Hilfsmitteln, wie Spannklauen festgespannt werden.The bearing blocks 12 and 13, together with the receiving devices 10 and 11, can be displaced along the slide guides 9 in the direction of the 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 pedestals 12 and 13 can be shown schematically Show dashed lines, downward extension bracket 23 and 24. Each downward constriction 23, 24 is operatively connected to a threaded spindle 25 or 26, each of which can be driven in the direction of the arrow (g). For this purpose, each threaded spindle 25 or 26 is operatively connected in a known manner, not shown, with a handwheel, via which the receiving devices 10 and 11, as well as the bearing pedestals 12 and 13, are displaced during rotary movement. These components can thus be positioned along the parallel sliding guides 9 in the desired position. In an obvious manner, each receiving device can be firmly clamped on the slide guides 9, for example using clamping screws or similar aids such as clamping claws.

Wie bereits vorher beschrieben, ist sowohl die Verlaengerung 17b des Endzapfens 17, als auch die Verlaengerung 18b des Endzapfens 18 des Druckzylinders 16 mit Verlaengerungshuelsen 19 und 20 bestueckt. Wie der Zeichnung deutlich zu entnehmen ist, haben die Verlaengerungshuelsen 19 und 20 aber keinerlei Stuetz- oder Lagerfunktion. Die auf der linken Seite der Zeichnung dargestellte Verlaengerung 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 ueber das zentrale Antriebssystem der Druckmaschine angetrieben und versetzt somit den Druckzylinder 16 in Drehbewegung. Zu diesem Zweck ist die Verlaengerung 19 fest mit der Verlaengerung 17b des Endzapfens 17, z.B. unter Zuhilfenahme einer durchgehenden Spannschraube 21 verbunden und, zwischen dem Verlaengerungstueck 17b des Endzapfens 17 und dem Ende der Verlaengerungshuelse 19 ist ein Verbindungskeil 29 eingesetzt. Auch die Verlaengerung 18b des Endzapfens 18 ist mit einer nicht tragenden Verlaengerungshuelse 20 verbunden und auch in diesem Falle findet fuer die feste Verbindung mit dem Endzapfen 18 eine Schraube und ein Keil 30 Verwendung. Das freie Ende der Verlaengerungshuelse 20 ist mit einer Drehvorrichtung 31 wirkverbunden. Diese Drehvorrichtung 31 hat die Aufgabe, den Druckzylinder 16 in seiner Winkelstellung zu positionieren, um zu gewaehrleisten, dass ueber gesamte Laenge der Druckmaschine saemtliche Druckzylinder einwandfrei untereinander ausgerichtet sind (Quereinstellung).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 clearly be seen in the drawing, the extension sleeves 19 and 20 have no support or storage function. The extension 19 shown on the left-hand side of the drawing accommodates a gearwheel 27 at its end which, for example, is brought into operative connection with a further gearwheel 28. The gear 28 is driven via 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 the extension 17b of the end pin 17, for example with the aid of a continuous tension screw 21, and between the extension piece 17b of the end pin 17 and the end of the extension sleeve 19 a connecting wedge 29 is inserted. 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 (transverse adjustment).

Wie der beigefuegten Zeichnung zu entnehmen ist, wird der Druckzylinder 16 in unmittelbarer Naehe seiner Endzapfen gelagert, und somit ist das entstehende Biegemoment wesentich 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 Gleitfuehrungen 9 des Wagens 1 verschoben und positioniert werden und der Austausch eines Druckzylinders 16 mit einem Druckzylinder, der andere Laengenabmessungen (1) aufweist, erfolgt schnell und ohne die Notwendigkeit, aufwendige und zeitraubende Montagearbeiten durchzufuehren.As can be seen from the attached 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 shifted 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 different length dimensions (1) takes place quickly and without the need for complex and time-consuming To carry out assembly work.

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