Description

Mit Endlospapier arbeitende elektrofotografische Druckeinrichtungen, wie sie z.B. aus der europäischen Patentanmeldung 0 154 695 bekannt sind, könen sowohl Rollenpapier als auch Stapelware bedrucken. Sie bedienen sich zur Papierführung mit Transportraupen, die in eine entsprechend gelochte Hilfsspur am Papierrand (Remaliner) eingreifen.Continuous paper electrophotographic printing equipment such as from the European patent application 0 154 695 are known, both roll paper and Print batch goods. They use the paper guide Transport caterpillars in a correspondingly perforated auxiliary track intervene at the paper edge (remaliner).

Das Bedrucken von Leporellopapier mit seitlich angeordneter Perforation ist technisch ausgereift und bewährt. Nachteilig ist jedoch, daß Papiere in jedem Fall konfektioniert werden müssen, ein zusätzlicher Papieranteil für die Lochspur bei der Beschaffung bezahlt und zudem diese Spur im Rahmen der Nachverarbeitung in der Regel wieder weggeschnitten und entsorgt wird. Hieraus ergeben sich im Zusammenhang mit der Transportlochspur deutlich erhöht Kosten für den Anwender.Printing on Leporello paper with a laterally arranged one Perforation is technically mature and proven. Disadvantageous is, however, that papers are always made up need, an additional paper portion for the hole track paid for the procurement and also this track as part of Post processing generally cut away and disposed of becomes. This results in connection with the Transport hole track significantly increases costs for the user.

In der Papiernachverarbeitungstechnik sind transportlochfreie Bahnführungen bekannt, welche meist in Verbindung mit aktiven Regeleinheiten (Drehrahmen) und perforierte Rollenware mit sehr hohen Zugspannungen exakt transportieren. Dieses Transportieren ist z.B. notwendig, wenn unmittelbar nach dem Verlassen der Druckeinrichtung die Randspur entfernt wird.In paper post-processing technology there are no transport holes Track guides are known, which are mostly in connection with active Control units (rotating frame) and perforated roll goods with transport very high tensile stresses exactly. This transportation is e.g. necessary if immediately after leaving the edge of the printing device is removed.

Bei Endlospapier verarbeiteten Datendruckern ist es generell notwendig, die Papierbahn sowohl bezüglich ihrer Geschwindigkeit, als auch hinsichtlich der seitlichen Lage exakt zu fuhren und so mit dem Druckwerk zu synchronisieren, daß die erforderliche Passergenauigkeit vom Druckbild zum Papier erreicht wird.It is general with data printers processed necessary the paper web both in terms of their speed, as well as the lateral position and to synchronize with the printing unit so that the required Registration accuracy achieved from print image to paper becomes.

Aus diesem Grunde war es bisher üblich, für elektrofotografische Druckeinrichtungen, die mit Endlospapier arbeiten, Papierbahnen zu verwenden, die seitliche Perforationen aufweisen.For this reason, it was previously common for electrophotographic Printing devices that work with continuous paper, paper webs to be used which have lateral perforations.

Aus den beschriebenen Grüden schränkt dies jedoch die Funktionsfähigkeit der elektrofotografischen Druckeinrichtung stark ein.For the reasons described, however, this limits the functionality the electrophotographic printing device strong one.

Wird in derartigen Druckeinrichtungen als Papierantrieb ein Friktionsantrieb verwendet, wie er z.B. in der beschriebenen Papiernachverarbeitungstechnik verwendet wird, so besteht die Gefahr, daß bei der Verwendung von Leporellopapier an den Querperforationen der Druckseiten die Perforation reißt. Andererseits ist es notwendig, die Endlospapier verarbeitenden Datendrucker so auszugestalten, daß sie sowohl perforiertes als auch unperforiertes Papier sowie perforierte und unperforierte Stapelware bewältigen.Used as a paper drive in such printing devices Friction drive, as used e.g. in the described Paper post-processing technology is used, so there is Risk that when using Leporello paper to the Cross perforations of the printed pages tear the perforation. On the other hand it is necessary to process the continuous forms To design data printers so that they are both perforated as well as imperforate paper and perforated and imperforate Master batch goods.

Aus der US-A-4 919 318 ist eine Druckvorrichtung zur Verarbeitung von länglichen Aufzeichnungsträgern bekannt, die einen Friktionsantrieb für den Aufzeichnungsträger aufweist sowie eine den Aufzeichnungsträger dem Friktionsantrieb zuführende Papierzuführeinrichtung. Diese Papierzuführeinrichtung enthält eine den Aufzeichnungsträger durch Zwangsführung an einer Ausrichtkante ausrichtende Vorzentriereinrichtung.From US-A-4 919 318 is a printing device for processing known from elongated record carriers that has a friction drive for the recording medium as well as a the record carrier the friction drive feeding paper feeder. This paper feeder contains a the record carrier by positive control pre-centering device aligned on an alignment edge.

Es ist weiterhin aus der DE-U-92 18 167.8 ein elektrofotografisches Druckgerät mit einer Anordnung zum automatischen Zuführen eines bandförmigen Aufzeichnungsträgers bekannt. Im Zuführkanal zur Fixierstation befindet sich ein mechanischer Bandspeicher in Form eines Schlaufenziehers, der die Aufgabe hat, den Papierlauf zu stabilisieren.It is also an electrophotographic from DE-U-92 18 167.8 Pressure device with an automatic arrangement Feeding a tape-shaped recording medium known. in the There is a mechanical feed channel to the fuser Tape storage in the form of a loop puller that does the job has to stabilize the paper flow.

Aufgabe der Erfindung ist es deshalb, eine Druckeinrichtung zur Verarbeitung von bandförmigen Aufzeichnungstägern bereitzustellen, bei der der bandförmige Aufzeichnungsträger mit Friktion angetrieben wird. Die Druckvorrichtung soll dabei perforiertes als auch unperforiertes Papier verarbeiten können. Ein weiteres Ziel der Erfindung ist es, für die Druckvorrichtung eine Papierführung für den bandförmigen Aufzeichnungsträger bereitzustellen, geeignet ist sowohl Rollenpapier als auch Stapelware in der geforderten Genauigkeit mit dem Druckwerk zu synchronisieren, ohne daß hierzu Transportlöcher als Führung benötigt werden.The object of the invention is therefore a printing device to provide for the processing of tape-shaped recording media, in which the tape-shaped recording medium is driven with friction. The printing device should Process perforated and imperforate paper can. Another object of the invention is for Printing device a paper guide for the tape-shaped recording medium both roll paper is suitable as well as stacked goods with the required accuracy to synchronize the printing unit without any transport holes are needed as a guide.

Diese Ziele der Erfindung werden gemäß den Merkmalen der Patentansprüche 1 und 10 gelöst.These objects of the invention are according to the features of the claims 1 and 10 solved.

Die erfindungsgemäße Druckeinrichtung ermöglicht die Verarbeitung von perforiertem und unperforiertem Papier mit hoher Positionsgenauigkeit. Die bei der Verwendung von perforiertem Papier auftretende Rißgefahr ist wesentlich reduziert. Die erfindungsgemäße Vorrichtung ist insbesondere geeignet zur Verwendung von Dokumenten-Druckeinrichtungen, bei denen bandförmige Aufzeichnungsträger geschnitten zu Einzelblättern vereinzelt und zu Dokumenten zusammengefaßt werden.The printing device according to the invention enables processing of perforated and imperforate paper with high Positional accuracy. The when using perforated The risk of tearing paper is significantly reduced. The The device according to the invention is particularly suitable for Use of document printing devices in which band-shaped Record carriers cut into single sheets isolated and combined into documents.

Eine Ausführungsform der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden beispielsweise näher beschrieben. Es zeigen

  • Figur 1 eine schematische Funktionsdarstellung einer Druckvorrichtung mit Friktionsantrieb zur Verarbeitung von Endlospapier und
  • Figur 2 eine schematische Darstellung einer Bahnvorzentriereinrichtung mit schräggestellten Friktionsrollen.
    • An embodiment of the invention is shown in the drawings and is described in more detail below, for example. Show it
  • Figure 1 is a schematic functional representation of a printing device with a friction drive for processing continuous paper and
  • Figure 2 is a schematic representation of a web pre-centering device with inclined friction rollers.

    • Die in den Figuren dargestellte Druckvorrichtung mit Friktionsantrieb zur Verarbeitung von bandförmigen Aufzeichnungsträgern A weist ein eigentliches Druckaggregat DA auf, das z.B. entsprechend der europäischen Patentanmeldung 0 154 695 ausgebildet sein kann und eine Papierzuführeinrichtung PZ. Das Druckaggregat DA ist zur Verarbeitung von Rollen- oder als Stapelware konfigurierten bandförmigen Aufzeichnungsträgern A ausgebildet. Es weist einen Friktionsantrieb aus zwei Friktionswalzen auf, zwischen denen der Aufzeichnungsträger hindurchgeführt wird. Zugeführt wird der bandförmige Aufzeichnungsträger A über eine Papierzuführeinrichtung PZ und zwar in der folgenden Weise. In einer Papiereingabeeinrichtung 1 wird das Endlospapier, das als vorgefaltetes Leporellopapier konfektioniert ist, jedoch keine seitlichen Transportlöcher aufweist, zunächst ohne wesentlichen Bahnzug über zwei feststehende Achsen 2 (Papierteiler) umgelenkt bzw. abgebremst. Die feststehenden Achsen 2 arbeiten sowohl als leichte Bremse als auch als Papierteiler, um z.B. mitgenommene Bahnlagen voneinander zu trennen. In einer Bahnvorzentrierung 3 wird die Papierbahn umgelenkt (ca. 90°) und mit Hilfe zweier schräggestellter, sich in Friktionskontakt mit dem Aufzeichnungsträger A befindlicher Friktionsrollen 4 (Figur 2) gegen eine linke Bahnbegrenzung 5 in Form eines Anschlages geschoben. Die Lage der Papierbahn bzw. des Aufzeichnungsträgers A wird also durch die Anlage der Bahnkante an der linken Bahnbegrenzung des Papierkanales der Papierzufuhreinrichtung bestimmt. Es ist jedoch auch möglich, durch entsprechende Anordnung der Rollen 4 die rechte Bahnbegrenzung zu verwenden.The pressure device with friction drive shown in the figures for processing tape-shaped recording media A has an actual printing unit DA, which e.g. according to European patent application 0 154 695 can be formed and a paper feed device PZ. The printing unit DA is for processing rolls or Configured in the form of stacks of tapes A trained. It has a friction drive made up of two Friction rollers on between which the record carrier is passed through. The tape-shaped recording medium is fed A via a paper feed device PZ and in the following way. In a paper input device 1 becomes the fanfold paper that serves as pre-folded fanfold paper is assembled, but no lateral transport holes exhibits, initially without substantial web tension two fixed axles 2 (paper divider) deflected or braked. The fixed axes 2 work both as light brake as well as a paper divider to e.g. taken away Separate web layers. In a web pre-centering 3 the paper web is deflected (approx. 90 °) and with Help two inclined, in frictional contact with the friction medium 4 located on the recording medium A (Figure 2) against a left web boundary 5 in the form of a stop pushed. The position of the paper web or the recording medium A is thus created by the creation of the web edge on the left path boundary of the paper channel of the paper feed device certainly. However, it is also possible to go through corresponding arrangement of the rollers 4 the right lane limitation to use.

    Nach der Bahnvorzentrierung über die Bahnvorzentriereinrichtung der Figur 2 wird durch eine Bahnbremse die Zugspannung in der Papierbahn A erhöht. Dabei ist es wichtig, daß die Papierbahn A nur in Transportrichtung und nicht schräg oder unsymmetrisch gebremst wird. Dies kann z.B. durch eine Unterdruckbremse 6 mit zugeordneter Vakuumpumpe 7 erfolgen. Durch die Zugspannung richtet sich die Papierbahn A im Antrieb 8 aus und sucht sich eine mittige Lage. Der Antrieb 8 der Papierführung ist als Friktionsantrieb mit möglichst wenig Schlupf bzw. gleichbleibenden Reibwert für die Lebensdauer ausgelegt, er enthält hierzu zwei Friktionswalzen 13, zwischen den der Aufzeichnungsträger hindurchgeführt wird.After web pre-centering using the web pre-centering device the figure 2 is the train tension by a train brake increased in paper web A. It is important that the paper web A only in the direction of transport and not at an angle or asymmetrically is braked. This can e.g. by a vacuum brake 6 with an assigned vacuum pump 7. By the tension is directed towards the paper web A in the drive 8 and looks for a central location. The drive 8 of the paper guide is as a friction drive with as little as possible Slip or constant coefficient of friction for the service life designed, for this purpose it contains two friction rollers 13, between which the record carrier is passed through.

    Je höcher die Zugspannung, desto geringer sind die seitlichen Pendelbewegungen der Bahn A und umgekehrt. Dieser Zusammenhang gilt auch fuhr die Ebenheit der Papierbahn A.The higher the tension, the lower the side Pendulum movements of web A and vice versa. This connection the flatness of paper web A also applies.

    Hinter der Unterdruckbremse 6 angeordnete Umlenkrollen 9 bilden eine Stabilisierungszone, in der der Papierlauf der Papierbahn A stabilisiert wird. Antriebsseitige Drifteinflüsse auf die Papierbahn bzw. auf die Anlage der Papierbahn an der Bahnbegrenzung 5 in der Bahnvorzentriereinrichtung 3 werden dadurch stark reduziert. Die Wirkung der Stabilisierungsrollen 9 ist bei möglichst großer Umschlingung (große Berührflächen) und mit Treibbelegen auf den Rollen besonders effektiv.Form deflection rollers 9 arranged behind the vacuum brake 6 a stabilization zone in which the paper path of the paper web A is stabilized. Drift influences on the drive side on the paper web or on the layout of the paper web on the Path limitation 5 in the web precenter 3 thereby greatly reduced. The effect of the stabilizing rollers 9 is with the largest possible wrap (large contact surfaces) and particularly effective with drift receipts on the reels.

    In der Stabilisierungszone ist ein mechanischer Bandspeicher in Form eines Schlaufenziehers 10 angeordnet, mit zwei feststehenden und einer Pendelwalze, die entgegen einer Feder bewegt wird. Der Schlaufenzieher hält die Papierbahn A bei Start-Stop bedingtem Rückwärtstransport unter Spannung. Er verhindert ein Zerreißen des Aufzeichnungsträgers. Die Zugspannung in der Papierbahn A liegt für diesen Fall etwas unter der sonst üblichen Spannung und ist über den gesamten Arbeitsbereich des Schlaufenziehers 10 bis zum Anschlag 5 annähernd konstant. Nach Durchlaufen des Schlaufenzierhers 10 wird die Papierbahn A dem Friktionsantrieb 8 des Druckaggregates DA zugeführt.There is a mechanical tape storage in the stabilization zone arranged in the form of a loop puller 10, with two fixed and a pendulum roller that moves against a spring becomes. The loop puller maintains paper web A. Start-stop caused reverse transport under tension. He prevents the recording medium from tearing. The tension in this case, paper web A is slightly below the usual voltage and is over the entire work area of the loop puller 10 up to the stop 5 approximately constant. After passing through the loop decorator 10, the paper web A fed to the friction drive 8 of the printing unit DA.

    Wird die Druckeinrichtung mit Rollenpapier betrieben, das von einer Rolle 11 abgezogen wird, ist es günstig, die Rolle 11 wie dargestellt separat anzutreiben bzw. zu bremsen. Der Antrieb der Rolle 11 bzw. deren Bremse wird so gesteuert, daß sich zwischen Rolle 11 und Papierangabe 1 eine definierte Schlaufe 12 bildet, die als mechanischer Papierspeicher dient. Der Einzug in die Bahnvorzentrierung 3 findet damit unter ähnlichen Bedingungen statt, wie bei einem Betrieb von Endlospapierstapeln der Papiereingabe 1. Zusammenfassend läßt sich die Endlospapierführung funktionell in folgende Schritte unterteilen: Papiereingabe über Rolle oder Stapeln mit folgender Bahnvorzentrierung durch seitliche Papieranlage in einer Bahnvorzentriereinrichtung. Erhöhen der Zugspannung mit Hilfe einer Bahnbremse. Stabilisierung der Aufzeichnungsträgerbahn in einer Bahnstabilisierungseinrichtung mit gerichteter Rückwirkung. Durchlaufen eines Schlaufenziehers, um das Zerreissen der Aufzeichnungsträgerbahn im Start-Stop-Betrieb zu verhindern und Transport der Aufzeichnungsträgerbahn durch die Druckeinrichtung in einem Friktionsantrieb. If the printing device is operated with roll paper, which by a roll 11 is withdrawn, it is convenient to roll 11 to drive or brake separately as shown. The drive the roller 11 or its brake is controlled so that a defined between roll 11 and paper specification 1 Loop 12 forms that as a mechanical paper storage serves. The move into the pre-centering 3 takes place under conditions similar to those of an operation of Continuous paper stacks of paper input 1. In summary lets the continuous paper guide is functional in the following steps divide: paper input via roll or stack with the following Web pre-centering through lateral paper feed in one Web pre-centering device. Increase the tension with Help of a train brake. Stabilization of the record carrier web in a web stabilization device with directed Retroactive effect. Going through a loop puller to do that Tear the record carrier web in start-stop mode to prevent and transport the record carrier through the printing device in a friction drive.
