Description

Die Erfindung bezieht sich auf eine Papier-Transporteinrichtung zwischen einem nach dem Tintenstrahlprinzip arbeitenden Plotter für grossflächige Papierbogen, einem Überleitteil und einem anschliessenden Falter sowie auf ein Verfahren zum Betrieb einer solchen Papiertransporteinrichtung.The invention relates to a paper transport device between an inkjet-based plotter for large areas Sheets of paper, a transfer part and a subsequent folder as well to a method for operating such a paper transport device.

Die handelsüblichen Platten zur Bedruckung grossflächiger Papierbogen arbeiten nach dem xerographischen Verfahren, welches eine kontinuierliche Blattausgabe ermöglicht, was für den nachfolgenden Faltvorgang im online-Betrieb zweckmässig ist. The commercially available plates for printing large sheets of paper work according to the xerographic process, which is a continuous Sheet output enables what for the subsequent folding process in online operation is appropriate.

Technische Verbesserungen bei Druckvorgängen im Tintenstrahlverfahren erlauben es zunehmend, auch grossflächige Papierbogen rationell zu bedrucken. Für den nachfolgenden "online" Anschluss eines Falters ist der unumgängliche zeilenweise und damit ruckartige Vorschub des Plotters bei der Blattausgabe nachteilig.Technical improvements in inkjet printing increasingly make it possible to rationally print even large sheets of paper. For the subsequent "online" connection of a folder is the inevitable line by line and thus jerky feed of the plotter the sheet issue disadvantageous.

Die mit der Erfindung zu lösende Aufgabe besteht darin, Mittel anzugeben, die erlauben einen tintenstrahldruckenden Plotter direkt an einen Falter anzuschliessen, ohne dass dieser in einem für die Faltvorgänge ungünstigen Moment anhalten muss.The object to be achieved with the invention is to specify means they allow an inkjet printing plotter directly to one Connect moths without them being unfavorable for the folding processes Moment must stop.

Die Erfindung mit der dieses Problem gelöst wird ergibt sich aus dem kennzeichnenden Teil der Ansprüche 1 und 8.The invention with which this problem is solved results from the characterizing part of claims 1 and 8.

Dadurch ist es möglich, den Falter mit kontinuierlicher Arbeitsgeschwindigkeit zu betreiben, unabhängig von der ruckweisen Papierbogen-Ausgabe des Plotters.This makes it possible to use the moth at a continuous working speed to operate, regardless of the jerky paper sheet output of the plotter.

Die Papiertransporteinrichtung dient zur Zufuhr von relativ grossflächigen Papierbogen 3 von einem Plotter 1 zu einer Faltmaschine, nachfolgend kurz Falter genannt. Eine Ausführungsform eines derartigen Falters geht beispielsweise aus der EP 0 587 531 hervor.The paper transport device is used to feed relatively large areas Sheet of paper 3 from a plotter 1 to a folding machine, below for short called moth. An embodiment of such a folder is possible for example from EP 0 587 531.

Ein Papierbogen 3, der durch an sich bekanntes Tintenstrahldruck-Verfahren im Plotter bedruckt wird, gelangt über eine V-förmige Einlaufschleuse 4 auf die Oberseite eines tischförmigen Überleitteiles 7. Der untere Teil der Einlaufschleuse 4 wird durch eine beweglich gelagerte Klappe 5 gebildet. Der Einlauf der Papiervorderkante wird durch einen Sensor 6 überwacht. Bei einer Weiterbewegung des Papierbogens 3 in Richtung des Pfeiles A gelangt das Papierband 3 in den Bereich einer Fixierklemme 10 und eines anschliessenden Sensors 13.A sheet of paper 3, which is produced by an ink jet printing method known per se printed in the plotter is passed through a V-shaped inlet lock 4 on top of a table-shaped transfer part 7. The lower one Part of the inlet lock 4 is by a movably mounted flap 5 formed. The entry of the leading edge of the paper is by a sensor 6 monitors. With a further movement of the paper sheet 3 in the direction arrow A, the paper tape 3 reaches the area of a fixing clamp 10 and a subsequent sensor 13.

Da der Druck des Papierbogens 3 zeilenweise und daher die Papiervorschubbewegung ruckartig erfolgt - was durch das Tintenstrahldruck-Verfahren systembedingt ist - müssen Rückhalteorgane vorgesehen werden, um den Papierbogen 3 dem Falter 2 kontinuierlich zuführen zu können, da der Faltvorgang nicht beliebig unterbrochen werden kann. Um dies zu erreichen, ist die Bildung einer Papierschlaufe 9 vorgesehen. Die Papierschlaufe 9 wird dadurch gebildet, dass die sich nahe beim Einlassbereich des Überleitteiles 7 befindliche elektromagnetisch betätigbare, als Rückhalteorgane wirkende Fixierklemme 10 von einem durch einen Sensor 13 beeinflusste Steuereinrichtung in Klemmposition gebracht wird und somit den Papierbogen 3 auf dem Überleitteil 7 festgeklemmt wird. Gleichzeitig gelangt die Klappe 5 in ihre abgesenkte Lage, wie dies aus Fig.2 ersichtlich ist.Since the printing of the paper sheet 3 line by line and therefore the paper feed movement jerky - what happens through the inkjet printing process is due to the system - retention devices must be provided, in order to be able to feed the sheet of paper 3 to the folder 2 continuously, since the folding process cannot be interrupted at will. To do this to achieve, the formation of a paper loop 9 is provided. The paper loop 9 is formed by the fact that it is close to the inlet area the transfer part 7 located electromagnetically operable as Retaining organs fixing clamp 10 by a sensor 13 influenced control device is brought into the clamping position and thus the paper sheet 3 is clamped on the transfer part 7. At the same time, the flap 5 comes into its lowered position, like this Fig. 2 can be seen.

Da vom Printer 1 ruckweise ständig ein Papiervorschub stattfindet, bildet sich eine Schlaufe 9. Sobald die Papierschlaufe 9 eine vorbestimmte maximale Länge erreicht hat (Fig.3), wird dies von einem Sensor 12 festgestellt. Die Steuereinrichtung bewirkt nun, dass die Fixierklemme 10 gelöst wird und eine Anpressrolle 14 von oben auf die ihr gegenüberliegende Antriebswelle 16 abgesenkt wird für den Papiertransport.Since the printer 1 jerkily takes a paper feed, forms a loop 9. As soon as the paper loop 9 a predetermined maximum Has reached length (Figure 3), this is determined by a sensor 12. The control device now causes the fixing clamp 10 to be released and a pressure roller 14 from above onto the opposite one Drive shaft 16 is lowered for paper transport.

Die unteren Rollen der Antriebsrollen-Paare 8 werden gemeinsam, vorzugsweise durch einen Zahnriemen kontinuierlich durch einen separaten Antrieb angetrieben. Die oberen Rollen der Antriebsrollen-Paare 8 liegen ohne eigenen Antrieb auf dem dazwischen befindlichen Papierband auf.The lower rollers of the drive roller pairs 8 are together, preferably through a toothed belt continuously through a separate one Drive driven. The upper rollers of the drive roller pairs 8 are located without its own drive on the paper tape in between.

Nachdem der Falter 2 gestartet ist, wird der Papierbogen 3 dem Falter 2 mit einer auf die Antriebsgeschwindigkeit des Falters 2 abgestimmten Geschwindigkeit zugeführt, wobei der Schlaufenvorrat kontinuierlich aufgebraucht wird. Sobald die Papierschlaufe 9 eine vorbestimmte Minimalgrösse erreicht hat, stellt dies ein weiterer Sensor 18 fest. Die Steuereinrichtung bewirkt nun, dass der Falter 2 stoppt, bis der Sensor 12 wieder eine grosse Schlaufenbildung feststellt. Der Unterbruch des Falterbetriebes wird allenfalls mittels Verzögerungsmitteln so gesteuert, dass er nicht in einer für den Faltvorgang kritischen Arbeitsphase unterbrochen wird. Der beschriebene Vorgang der Faltenbildung wiederholt sich bis zum Papierbogen-Ende, worauf wieder die in Fig.1 beschriebene Situation vorliegt und die Klappe 5 angehoben wird.After the folder 2 has started, the paper sheet 3 becomes the folder 2 with a speed matched to the drive speed of the folder 2 fed, the loop supply continuously used up becomes. As soon as the paper loop 9 has a predetermined minimum size has reached, another sensor 18 detects this. The control device now causes the folder 2 to stop until the sensor 12 is one again large loop formation. The interruption of the butterfly business is controlled at most by means of delay means so that it is not in a critical work phase for the folding process is interrupted. The The process of wrinkling described is repeated until the end of the paper sheet, whereupon the situation described in FIG. 1 is again present and the flap 5 is raised.

Eine Ausführungsvariante besteht darin, dass die Transportrollen-Paare 8 nicht von einem separaten Antrieb, sondern direkt vom Falter 2 angetrieben werden. Sobald der Sensor das Bogenende feststellt, wird die Faltergeschwindigkeit erhöht - also wesentlich über die durchschnittliche Plottergeschwindigkeit. Für den nächsten Papierbogen 3 wird die Klappe 5 wieder angehoben und es liegt die Ausgangssituation analog zu Fig. 1 vor.One embodiment variant is that the transport roller pairs 8 not from a separate drive, but driven directly from folder 2 become. As soon as the sensor detects the end of the sheet, the speed of the butterfly changes increased - significantly above the average plotter speed. For the next sheet of paper 3, the flap 5 raised again and the starting situation is analogous to FIG. 1.

In Fig.4 ist eine weitere Ausführungsvariante dargestellt. Die Schlaufenbildung 9 erfolgt in gleicher Weise, wie im Zusammenhang mit den Fig.2 und 3 beschrieben wurde. Die Transportrollen 16' und 8' werden durch einen separaten Antrieb so angetrieben, gesteuert durch die Sensoren 12 und 13, dass die Papierschlaufe 9 zwischen einer minimalen und einer maximalen Länge pendelt. Die Transportrollen-Paare 8 werden direkt vom Falter 2 angetrieben. Dabei kann sich ein weiterer Papiervorrat in Form einer zweiten Papierschlaufe 20 bilden, die sich gegenüber dem Überleitteil 7 vorzugsweise nach oben erstreckt. Sobald der Sensor 6 das Papierbogen-Ende feststellt, wird der Falter 2 auf hohe Faltgeschwindigkeit geschaltet, die höher ist als die durchschnittliche Plottergeschwindigkeit. Die Klappe 5 wird in ihre Ausgangslage angehoben. Ein nächster Papierbogen 3 kann zugeführt und geklemmt werden, wie dies im Zusammenhang mit Fig. 1 und 2 bereits beschrieben wurde.A further embodiment variant is shown in FIG. The loop formation 9 takes place in the same way as in connection with FIG. 2 and 3 has been described. The transport rollers 16 'and 8' are through a separate drive so driven, controlled by the sensors 12 and 13 that the paper loop 9 between a minimum and a maximum Length commutes. The transport roller pairs 8 are directly from Moth 2 driven. Another paper supply can take shape form a second paper loop 20, which is opposite the transfer part 7 preferably extends upwards. Once the sensor 6 the paper sheet end determines, the folder 2 is switched to high folding speed, which is higher than the average plotter speed. The Flap 5 is raised to its initial position. Another sheet of paper 3 can be fed and clamped as related to 1 and 2 have already been described.

Eine weitere Ausführungsform ist in Fig.5 dargestellt, Hier ist die Faltgeschwindigkeit im wesentlichen auf die mittlere Plottergeschwindigkeit abgestimmt. Alle Transportrollen-Paare 8 auf dem Überleitteil 7 transportieren ruckweise mittels eines separaten Antriebes. Wie bereits im Zusammenhang mit den Fig. 2 und 3 beschrieben, pendelt die Länge der Papierschlaufe 9 zwischen einer minimalen und einer maximalen Länge. Vor den kontinuierlich drehenden Antriebsrollen 22 des Falters 2 bildet sich anschliessend an den Überleitteil 7 eine nach unten ragende Schlaufe 24 zum Ausgleich der ruckartig zugeführten Papierbewegungen. Sobald der Sensor 6 das Papierbogenende feststellt, schaltet die Steuereinrichtung den Falter 2 auf hohe Faltgeschwindigkeit, die höher ist als die durchschnittliche Plottergeschwindigkeit. Bei einem nächsten Papierbogen wiederholen sich die Einzugsvorgänge, wie im Zusammenhang mit den Fig.1-3 beschrieben wurde.Another embodiment is shown in Figure 5, here is the folding speed essentially matched to the average plotter speed. Transport all pairs of transport rollers 8 on the transfer part 7 jerkily by means of a separate drive. As already related described with FIGS. 2 and 3, the length of the paper loop oscillates 9 between a minimum and a maximum length. Before Continuously rotating drive rollers 22 of the folder 2 then form to the transfer part 7 a downwardly projecting loop 24 for Compensation for jerky paper movements. Once the sensor 6 detects the paper sheet end, the control device switches the folder 2 to high folding speed, which is higher than the average Plotter speed. Repeat the next sheet of paper the pull-in processes, as described in connection with Fig.1-3 has been.

Die Papierschlaufen 9, 20 und 24 könnten sich wahlweise nach unten oder nach oben wölben.The paper loops 9, 20 and 24 could be either down or arch upwards.

In Fig. 5 ist eine weitere Ausführungsvariante dargestellt. Der Falter 2 befindet sich vorerst im Ruhezustand und die Klappe 5 nimmt ihre obere Endlage ein. Bei der Papierausgabe des Plotters 1 gelangt die Papiervorderkante am Sensor 6 vorbei auf den Ueberleitteil 7. Der Sensor 6 bewirkt, dass ein als Rückhalteorgan ausgebildetes Rollenpaar 26 am Eintrittsbereich des Ueberleitteils 7 startet. Den Antrieb des Rollenpaares 26 erfolgt durch einen unabhängigen Antrieb, wobei die Antriebsgeschwindigkeit geringer ist als die Blattausgabegeschwindigkeit des Plotters 1. Sobald die Blattvorderkante in den Bereich des Sensors 13 gelangt, stoppt der Antrieb des Rollenpaares 26. Die Klappe 5 schwenkt nach unten, worauf sich eine Papierschlaufe 9 bildet. 5 shows a further embodiment variant. The moth 2 is located is initially in the idle state and the flap 5 takes its upper End position. When the plotter 1 outputs paper, the leading edge of the paper arrives past the sensor 6 to the transfer part 7. The sensor 6 causes that a pair of rollers 26 designed as a retaining member at the entry area of the transfer part 7 starts. The roller pair 26 is driven through an independent drive, the drive speed is lower than the sheet output speed of the plotter 1. As soon as the If the leading edge of the sheet reaches the area of the sensor 13, the drive stops of the pair of rollers 26. The flap 5 swings down, whereupon one Paper loop 9 forms.

Sobald der Sensor 12 die Maximallänge der Schlaufe 9 feststellt, startet sowohl der Antrieb der Rollen 26 als auch der Antrieb des Falters. Das Papierband 3 gelangt dann in den Bereich der Rollen 8 und wird mit der Falterarbeitsgeschwindigkeit dem Falter 2 zugeführt. Die Rollen 26 werden dabei durch ihre Ueberholkupplungen lose mitgedreht. Als Folge des Papierbandtransporters in Richtung A verkürzt sich sodann die Schlaufe 9 bis der Sensor 18 die Minimalgrösse der Schlaufe 9 feststellt. Der Antrieb der Rollen 8 sowie der Antrieb des Falters stoppen bis die Schlaufe 9 wieder die durch den Sensor 12 festgestellte Maximallänge erreicht hat. Hierauf wiederholen sich die Vorgänge analog, wie sie im Zusammenhang mit den Fig. 1-3 beschrieben wurden.As soon as the sensor 12 determines the maximum length of the loop 9, starts both the drive of the rollers 26 and the drive of the folder. The Paper tape 3 then gets into the area of the rollers 8 and is with the Butterfly working speed fed to the folder 2. The rollers 26 are loosely rotated by their overrunning clutches. As a result of The paper belt transporter in direction A then shortens the loop 9 until the sensor 18 detects the minimum size of the loop 9. The drive the rollers 8 and the drive of the folder stop until the loop 9 again has reached the maximum length determined by the sensor 12. hereupon the processes are repeated analogously as they are in connection with 1-3 have been described.

Die Erfindung ist mit den obigen Ausführungsbeispielen ausreichend dargetan. Sie könnte jedoch beispielsweise mit einem anderen Plotter als einem Tintenstrahlprinzip funktioniereen. Selbstverständlich könnte die Schlaufe des herankommenden Papierbogens statt nach unten auch nach oben ausgerichtete sein. Im Prinzip könnte auch auf die bewegliche Klappe 5 verzichtet werden oder sie könnte durch ein anderes Mittel ersetzt sein.The invention is sufficiently demonstrated with the above exemplary embodiments. However, you could, for example, use a plotter other than one Inkjet principle work. Of course that could Loop the approaching paper sheet down instead of down be aligned above. In principle, it could also be on the movable flap 5 can be waived or it could be replaced by another means his.

Auch anstelle der Sensoren 6, 12, 18 könnten andere Mittel vorgesehen sein, so zum Beispiel entsprechende Schrittmotoren oder Zeitmesseinrichtungen, durch welche die Länge des zum Plotter vorstehenden Papierbogens bestimmt werden könnte.Other means could also be provided instead of the sensors 6, 12, 18 be, for example, corresponding stepper motors or timing devices, by which the length of the sheet of paper protruding from the plotter could be determined.
