Description

Die vorstehende Erfindung betrifft ein Verfahren, mit dem es moeglich ist, automatisch Druckzylinderaufnahmewagen in die Druckelemente einzufahren.The above invention relates to a method with which it is possible to automatically move printing cylinder receiving carriages into the printing elements.

Es ist bekannt, dass Rotationsdruckmaschinen aus einer Serie von Druckelementen bestehen, die untereinander auf Abstand angeordnet sind und mit bekannten mechanischen Einrichtungen ausgeruestet sind, die es ermoeglichen, die zu bedruckende Papierbahn durch eine Vielzahl von hintereinander angeordneten Druckelementen zu bewegen. Jedes dieser Druckelemente weist in bekannter Weise eine Anpressrolle auf, welche die Aufgabe hat, die Papierbahn an einen Druckzylinder zu druecken. Jeder Druckzylinder ist in einem eigenen Aufnahmewagen gelagert und jeder Aufnahmewagen weist eine bekannte Rakelvorrichtung sowie eine Farbauftragsvorrichtung auf.It is known that rotary printing presses consist of a series of printing elements which are arranged at a distance from one another and are equipped with known mechanical devices which make it possible to move the paper web to be printed by a large number of printing elements arranged one behind the other. Each of these printing elements has a pressure roller in a known manner, which has the task of pressing the paper web against a printing cylinder. Each printing cylinder is mounted in its own receiving carriage and each receiving carriage has a known doctor device and an ink application device.

Es ist bekannt, dass bei Wechsel des Druckprogrammes, wenn z.B. vom Druck eines bestimmten Erzeugnisses auf den Druck eines anderen Erzeugnisses uebergegangen wird, die Notwendigkeit besteht, die Rotationsdruckmaschine anzuhalten, um zu ermoeglichen, die einzelnen Druckzylinderaufnahmewagen aus den Druckelementen auszufahren. Im Anschluss daran, muessen die nicht mehr zum Einsatz kommenden Druckzylinderaufnahmewagen vom zugeordneten Druckelement abtransportiert werden, und nur dann ist es moeglich, neue Druckzylinderaufnahmewagen in die Zwischenraeume, die zwischen den Druckelementen vorgesehen sind, einzufahren, um anschliessend die Aufnahmewagen mit den neuen Zylindern in die Druckeinheiten einzufahren, um nach Durchfuehrung der bisher beschriebenen Vorgaenge den Druckvorgang des neuen Erzeugnisses anzufahren.It is known that when changing the print program, if For example, from the printing of a certain product to the printing of another product, there is a need to stop the rotary printing press in order to enable the individual printing cylinder pick-up carriages to move out of the printing elements. Subsequently, the printing cylinder receiving carriages that are no longer used must be removed from the assigned pressure element, and only then is it possible to insert new printing cylinder receiving carriages into the spaces that are provided between the printing elements, and then the receiving carriages with the new cylinders into the Retract printing units in order to start the printing process of the new product after carrying out the previously described processes.

Beruecksichtigt man, dass die zu leistenden Investitionen fuer eine Druckmaschine sehr hoch sind, so wird verstaendlich, dass eine Druckerei versuchen wird, die Stillstandszeiten der Maschine auf ein Minimum zu senken, das heisst jene Stillstandszeiten, die fuer den Austausch der Druckzylinderaufnahmewagen erforderlich sind, ein Vorgang, der auch heute noch zum Grossteil von Hand durchgefuehrt wird.If one takes into account that the investments to be made for a printing press are very high, it is understandable that a printing house will try to reduce the downtimes of the press to a minimum, i.e. the downtimes which are necessary for the exchange of the printing cylinder receiving carriages Process that is still largely carried out by hand.

Es ist aus dem Stand der Technik eine Einrichtung bekannt geworden, bei der in Achse mit den Druckelementen eine Transportvorrichtung vorgesehen ist, auf der die Druckzylinderaufnahmewagen angeordnet sind, um die Wagen aus einer Wartestellung in den Zwischenraum zwischen jeweils zwei Druckelementen einzufahren und im Anschluss daran, ein Einfahren des entsprechenden Druckzylinderaufnahmewagens in das Druckelement durchzufuehren.A device has become known from the prior art, in which a transport device is provided in axis with the printing elements, on which the printing cylinder receiving carriage are arranged to move the carriage from a waiting position into the space between each two printing elements and then to drive the corresponding printing cylinder receiving carriage into the printing element.

Will man die Druckzylinder durch neue Zylinder austauschen, so werden die Zylinder durch die einzelnen Druckeinheiten hindurchgeschoben, um den anschliessenden Freiraum zwischen zwei Druckelementen zu besetzen, und im Anschluss daran durch eine Querbewegung erneut auf der Transporteinrichtung abgelagert.If you want to replace the printing cylinders with new cylinders, the cylinders are pushed through the individual printing units in order to occupy the subsequent free space between two printing elements and then deposited again on the transport device by a transverse movement.

Diese bekannte Einrichtung hat den Nachteil, dass es erforderlich ist, in Laengsrichtung der Rotationsdruckmaschine einen tiefen Kanal vorzusehen, der geeignet ist, die Bauteile fuer die Transporteinrichtung der Druckzylinderaufnahmewagen aufzunehmen.This known device has the disadvantage that it is necessary to provide a deep channel in the longitudinal direction of the rotary printing press, which channel is suitable for receiving the components for the transport device of the printing cylinder receiving carriage.

Die Notwendigkeit, einen Kanal, der sich ueber die gesamte Laenge der Rotationsdruckmaschine erstreckt, vorzusehen, bringt erhebliche Nachteile mit sich und ist technisch oft nicht durchfuehrbar, z.B. wenn die Rotationsdruckmaschine auf einem Boden montiert ist, der aus statischen Gruenden nicht veraendert werden darf.The need to provide a channel that extends over the entire length of the rotary printing machine has considerable disadvantages and is often not technically feasible, e.g. if the rotary printing press is mounted on a floor that must not be changed for static reasons.

Es ist auch eine Rotationsdruckmaschine bekanntgeworden, bei der der Versuch unternommen wurde, die Stillstandszeiten fuer das Austauschen der Druckzylinderaufnahmewagen dadurch zu vermindern, dass fuer jedes Druckelement ein doppelt ausgefuehrter Druckzylinderaufnahmewagen vorgesehen ist, das heisst ein Aufnahmewagen, der zur Aufnahme von zwei Druckzylindern, zwei Rakeleinrichtungen und zwei entsprechenden Farbauftragseinrichtungen ausgebildet ist.A rotary printing press has also become known in which an attempt has been made to reduce the downtimes for exchanging the printing cylinder receiving carriages to reduce the fact that for each printing element there is a double printing cylinder receiving carriage, that is to say a receiving carriage which is designed to receive two printing cylinders, two doctor blades and two corresponding ink application devices.

Der Nachteil dieser Ausfuehrungsform ist darin zu sehen, dass zum Einfahren eines Druckzylinderaufnahmewagens mit doppelter Breite in den Zwischenraum zwischen zwei Druckelementen dieser Freiraum in seinen Abmessungen zu verdoppeln ist, was dazu fuehrt, dass die gesamte Laenge der Rotationsdruckmaschine in unerwuenschter Weise zunimmt.The disadvantage of this embodiment is to be seen in the fact that for the insertion of a double-width impression cylinder carriage into the space between two printing elements, the size of this free space has to be doubled, which means that the entire length of the rotary printing press increases in an undesirable manner.

Des weiteren ist bei der Verwendung von Aufnahmewagen fuer zwei Druckzylinder eine gewisse Traegheit in der Verschiebebewegung festzustellen und erlaubt es nicht, im Bedarfsfall den Druckzylinderaufnahmewagen, der sich gerade in Wartestellung befindet, durch einen anderen Druckzylinderaufnahmewagen, der mit einem unterschiedlichen Druckzylinder ausgeruestet ist, auszutauschen.Furthermore, when using carriage for two printing cylinders, a certain sluggishness in the displacement movement can be determined and does not allow, if necessary, the printing cylinder receiving carriage, which is currently in the waiting position, to be replaced by another printing cylinder receiving carriage, which is equipped with a different printing cylinder.

Ein weiterer Nachteil ist darin zu sehen, dass die Aufnahmewagen fuer zwei Druckzylinder sehr schwer sind und demzufolge ein grosser Kraftaufwand fuer das Verfahren dieser Druckzylinderaufnahmewagen erforderlich ist.Another disadvantage can be seen in the fact that the receiving carriages for two printing cylinders are very heavy and consequently a great deal of effort is required to move these printing cylinder receiving carriages.

Aufgabe der vorstehenden Erfindung ist es, die Nachteile des Standes der Technik zu vermeiden und ein Verfahren vorzuschlagen, bei dem es moeglich ist, auf eine Transporteinrichtung fuer die Druckzylinderaufnahmewagen und demzufolge auch auf einen entsprechenden Aufnahmekanal fuer diese Transporteinrichtung zu verzichten und die Moeglichkeit zu schaffen, unter Vorsehung eines begrenzten Freiraumes zwischen jeweils zwei Druckelementen einen Druckzylinderaufnahmewagen in Wartestellung zu halten, und dadurch die Laenge der gesamten Rotationsdruckmaschine auf ein Minimum zu beschraenken und gleichzeitig die Moeglichkeit zu eroeffnen, den Austausch der Druckzylinderaufnahmewagen einfach und mit kurzen Zeiten durchzufuehren. Erfindungsgemaess wird diese Aufgabe durch ein Verfahren geloest, das sich dadurch gekennzeichnet, dass ein gleichzeitiges Verschieben aller Druckzylinderaufnahmewagen (A1), die sich in den Druckelementen (1,2,3) befinden, zusammen mit allen Druckzylinderaufnahmewagen (B1), die sich in Wartestellung zwischen den entsprechenden Druckelementen (1,2,3) befinden, in einer Vorschubrichtung (f) erfolgt und dass fuer das darauffolgende Auswechseln der Druckzylinderaufnahmewagen ein Verschieben der Druckzylinderaufnahmewagen (B1), die sich in den Druckelementen (1,2,3) befinden, sowie der Druckzylinderaufnahmewagen (A2), die sich in Wartestellung zwischen den Druckelementen (1,2,3) befinden, gleichzeitig und zusammen, in entgegengesetzter Bichtung (g) erfolgt. Mit der Durchfuehrung dieser pendelartigen Verschiebebewegung waehrend des Belade- oder Entladevorganges, die gleichzeitig fuer alle Druckzylinderaufnahmewagen einmal in einer Laengsrichtung der Rotationsdruckmaschine und anschliessend in der entgegengesetzten Laengsrichtung der Rotationsdruckmaschine erfolgt, wird es moeglich, den Austausch der Druckzylinderaufnahmewagen auf sehr schnelle Weise durchzufuehren, und es wird die Moeglichkeit geschaffen, Aenderungen im Druckprogramm auch in letzter Minute durchzufuehren und vor allem die Stillstandszeiten der Druckmaschine auf ein Minimum zu senken. Ferner ist es moeglich, eine in der Laengenerstreckung kurze Rotationsdruckmaschine zu bauen.The object of the above invention is to avoid the disadvantages of the prior art and a method to propose, in which it is possible to dispense with a transport device for the printing cylinder receiving carriage and consequently also with a corresponding receiving channel for this transport device and to make it possible to keep a printing cylinder receiving carriage waiting while providing for a limited space between two printing elements, and thereby to limit the length of the entire rotary printing press to a minimum and at the same time to open up the possibility of carrying out the exchange of the printing cylinder receiving carriages simply and with short times. According to the invention, this object is achieved by a method which is characterized in that a simultaneous shifting of all printing cylinder receiving carriages (A1) which are located in the printing elements (1, 2, 3) together with all printing cylinder receiving carriages (B1) which are in the waiting position are located between the corresponding printing elements (1, 2, 3) in a feed direction (f) and that for the subsequent replacement of the printing cylinder receiving carriages, the printing cylinder receiving carriages (B1) located in the printing elements (1, 2, 3) are shifted, and the printing cylinder receiving carriage (A2), which is in the waiting position between the printing elements (1, 2, 3), takes place simultaneously and together, in the opposite direction (g). With the Carrying out this pendulum-like shifting movement during the loading or unloading process, which takes place simultaneously for all printing cylinder receiving carriages once in a longitudinal direction of the rotary printing press and then in the opposite longitudinal direction of the rotary printing press, it becomes possible to carry out the exchange of the printing cylinder receiving carriages very quickly, and it will be Possibility created to make changes in the printing program also in the last minute and above all to reduce the downtimes of the printing press to a minimum. It is also possible to build a rotary printing press that is short in length.

The subject of the invention will now be described in more detail and shown in the accompanying drawings. Show it:
  • Fig. 1 three pressure elements with the associated printing cylinder receiving carriage in the working position;
  • 2 shows the printing elements before the exchange of the printing cylinder receiving carriage;

Wie der Fig. 1 zu entnehmen ist, werden die Druckelemente 1, 2 und 3 von einer zu bedruckenden Bahn 4 durchlaufen. In jedem Druckelement 1,2,3 ist ein Druckzylinderaufnahmewagen A1 angeordnet. Jeder Aufnahmewagen A1 ist in bekannter Weise mit einem Druckzylinder ausgeruestet. Ferner weist jeder Wagen A1 eine bekannte Rakeleinrichtung sowie eine bekannte Farbauftragsvorrichtung auf.1, the printing elements 1, 2 and 3 are traversed by a web 4 to be printed. A printing cylinder receiving carriage A1 is arranged in each printing element 1, 2, 3. Each receiving carriage A1 is equipped with a pressure cylinder in a known manner. Furthermore, each carriage A1 has a known doctor device and a known ink application device.

In jedem Druckelement 1,2,3 ist eine Andrueckrolle 5,6 bzw. 7 vorgesehen, die anhebbar und absenkbar ist und die Bahn 4 gegen die Druckzylinder der Aufnahmewagen A1 presst. In Fig. 1 ist die Rotationsdruckmaschine schematisch waehrend des Druckvorganges dargestellt.A pressure roller 5, 6 or 7 is provided in each pressure element 1, 2, 3, which can be raised and lowered and presses the web 4 against the pressure cylinder of the receiving carriage A1. In Fig. 1 the rotary printing press is shown schematically during the printing process.

Wie der Fig. 2 zu entnehmen ist, werden waehrend des Druckvorganges in den Druckelementen 1, 2, 3, unter Zuhilfenahme der von den Aufnahmewagen A1 gehaltenen Druckzylinder, in die vor jedem Druckelement 1,2,3 gebildeten Freiraeume bereits Druckzylinderaufnahmewagen B1 eingefahren, die sich in Wartestellung befinden. Um die Wagen A1 durch die Druckzylinderaufnahmewagen B1, die sich in Wartestellung befinden, zu ersetzen, werden die Anpresszylinder 5,6,7 einer jeden Druckeinheit 1,2,3 angehoben; im Anschluss daran werden alle Wagen A1, B1 gleichzeitig und gemeinsam sowie in der gleichen Verschieberichtung, wie durch den Pfeil f angedeutet, verfahren. Mit anderen Worten, in der Darstellung gemaess Fig. 2 werden die Aufnahmewagen A1 und B1 von links nach rechts verfahren.As can be seen in FIG. 2, during the printing process in the printing elements 1, 2, 3, with the aid of the printing cylinders held by the receiving carriages A1, printing cylinder receiving carriages B1 are already inserted into the free spaces formed in front of each printing element 1, 2, 3 are on hold. In order to replace the carriages A1 with the printing cylinder receiving carriages B1, which are in the waiting position, the Pressure cylinder 5,6,7 of each printing unit 1,2,3 raised; Subsequently, all carriages A1, B1 are moved simultaneously and together and in the same direction of displacement, as indicated by the arrow f. In other words, in the illustration according to FIG. 2, the receiving carriages A1 and B1 are moved from left to right.

Damit wird bewirkt, dass die neuen Aufnahmewagen B1 in die Druckelemente 1, 2 und 3 eingefahren werden und gleichzeitig alle Aufnahmewagen A1 in einen Freiraum verfahren werden, der auf der rechten Seite der zugeordneten Druckelemente 1, 2 und 3 angeordnet ist.This has the effect that the new receiving carriages B1 are moved into the printing elements 1, 2 and 3 and at the same time all the receiving carriages A1 are moved into a free space which is arranged on the right side of the assigned printing elements 1, 2 and 3.

Dies bedeutet, dass die Aufnahmewagen B1 sofort zur Wiederaufnahme des Druckvorganges zur Verfuegung stehen, wogegen die Aufnahmewagen A1 in Richtung der mit S gekennzeichneten Strichpunktlinien abgefoerdert werden koennen.This means that the receiving carriages B1 are immediately available for resuming the printing process, whereas the receiving carriages A1 can be conveyed in the direction of the dash-dotted lines.

Der Fig. 4 kann entnommen werden, dass, waehrend sich die Druckzylinderaufnahmewagen B1 in Arbeitsstellung befinden, entlang des Verfahrweges C neue Druckzylinderaufnahmewagen A2 auf der rechten Seite der Druckelemente 1, 2 und 3 angeordnet werden, wo diese Aufnahmewagen A2 in Wartestellung verbleiben. Soll ein Austausch der Aufnahmewagen B1 mit den Aufnahmewagen A2 erfolgen, so wird die gesamte Wagengruppe B1 und A2 in der durch den Pfeil b gezeigten Richtung verschoben, das heisst von rechts nach links. Dadurch werden saemtliche Wagen B1 gleichzeitig aus den Druckeinheiten 1, 2 und 3 ausgefahren, wogegen saemtliche Aufnahmewagen A2 in das Innere der Druckeinheiten 1, 2 und 3 verschoben werden, um dort fuer den folgenden Druckvorgang zur Verfuegung zu stehen.4 that during the printing cylinder receiving carriages B1 are in the working position, new printing cylinder receiving carriages A2 are arranged along the travel path C on the right side of the printing elements 1, 2 and 3, where these receiving carriages A2 remain in the waiting position. If there is an exchange of the pick-up carriages B1 with the pick-up carriages A2, the entire carriage group B1 and A2 is shown in the arrow b Direction shifted, that means from right to left. As a result, all of the carriages B1 are moved out of the printing units 1, 2 and 3 at the same time, whereas all of the receiving carriages A2 are moved into the interior of the printing units 1, 2 and 3 in order to be available there for the following printing process.

Im Anschluss werden die Aufnahmewagen B1, wie in Fig. 5 dargestellt, entlang der Strichpunktlinie S abgefahren. Wie der Fig. 6 zu entnehmen ist, werden die Freiraeume, die sich nunmehr auf der linken Seite der Druckeinheiten 1, 2 und 3 gebildet haben, durch neue Aufnahmewagen B2 besetzt, welche in Wartestellung verbleiben.The receiving carriages B1 are then moved along the dash-dot line S, as shown in FIG. 5. As can be seen from FIG. 6, the free spaces which have now formed on the left side of the printing units 1, 2 and 3 are occupied by new receiving carriages B2, which remain in the waiting position.

Bei Austausch der Aufnahmewagen A2 wird die gesamte Wagengruppe, bestehend aus den Aufnahmewagen A2 und den Aufnahmewagen B2, erneut in Richtung des Pfeiles f verschoben, das heisst von links nach rechts, worauf sich der Beladezyklus wiederholt.When the pick-up carriages A2 are exchanged, the entire carriage group, consisting of the pick-up carriages A2 and the pick-up carriages B2, is again moved in the direction of the arrow f, that is to say from left to right, whereupon the loading cycle is repeated.

Der Erfinder hat vorgeschlagen, waehrend des Auswechselvorganges der Druckzylinderaufnahmewagen die gesamte Wagengruppe (bestehend aus Druckzylinderaufnahmewagen im Inneren der Druckeinheiten 1, 2 und 3 sowie Ersatzwagen, die in Wartestellung vor den Druckeinheiten 1, 2 und 3 angeordnet sind) mit pendelartiger Verschiebebewegung einmal gesamthaft nach rechts und im Anschluss gesamthaft nach links zu verschieben, dabei hat der Erfinder bemerkt, dass die Einrichtungen zum Steuern sowie zum Verfahren der Aufnahmewagen ausgesprochen einfach ausgebildet sein koennen.The inventor has proposed that during the process of replacing the printing cylinder receiving carriages, the entire carriage group (consisting of printing cylinder receiving carriages inside the printing units 1, 2 and 3, as well as replacement carriages, which are arranged in the waiting position in front of the printing units 1, 2 and 3) with a pendulum-like displacement movement once to the right and then move it to the left altogether, the inventor noticed that the devices for controlling and moving the receptacles can be extremely simple.

Mit der Erfindung wird es moeglich, alle Steuer- und Antriebsvorrichtungen fuer die Druckzylinderaufnahmewagen oberhalb des Fussbodens, auf dem die Rotationsdruckmaschine montiert ist, anzuordnen, es sind keine Unterbrechungen des Bodens, z. B. in Form von Ausnehmungen oder Kanaelen, vorzusehen. Dies ist besonders vorteilhaft, wenn man beruecksichtigt, dass in einer Rotationsdruckmaschine auch Leckverluste aufgrund von Oelverlust oder Farbaustritt auftreten koennen, welche Leckverluste bei eben ausgefuehrtem Boden leichter entfernt werden koennen.With the invention, it is possible to arrange all control and drive devices for the impression cylinder carriage above the floor on which the rotary printing press is mounted. There are no interruptions in the floor, e.g. B. in the form of recesses or channels. This is particularly advantageous if one takes into account that leakage losses due to oil loss or ink leakage can also occur in a rotary printing press, which leakage losses can be removed more easily when the floor is just executed.
