Description
Die Erfindung betrifft eine Vorrichtung zur Veränderung der Bahnlage einer Bedruckstoffbahn nach dem Oberbegriff von Anspruch 1.The invention relates to a device for changing the web position of a printing material web according to the preamble of claim 1.
Sowohl aus der DE 27 41 596 A1 als auch der DE 39 05 400 C2 ist es für mindestens zwei auf der Bedienseite übereinander angeordnete Druckwerke bekannt, daß das durch die Bedruckstoffbahn in der Betriebslage für einen Bedienenden verdeckte Druckwerk durch eine Lageveränderung der Bedruckstoffbahn außerhalb des Druckbetriebes unter Zuhilfenahme eines ortsveränderbaren Auftrittes für den Bedienenden zugängig ist.Both from DE 27 41 596 A1 and DE 39 05 400 C2 it is known for at least two printing units arranged one above the other on the operating side that the printing unit hidden by the printing material web in the operating position for an operator is caused by a change in the position of the printing material web outside of the printing operation is accessible to the operator with the help of a changeable appearance.
Diese Vorrichtungen arbeiten bei der Lageveränderung der Bedruckstoffbahn mit einer unveränderlichen Bahnlänge, wozu technisch und kostenaufwendige Mittel zur Bahnspeicherung und Bahnverdrängung sowie die Führung und Bewegung des in verschiedene Positionen verfahrbaren Auftrittes erforderlich sind. Zusätzliche Walzenkontakte erhöhen die Gefahr des Abschmierens der Druckfarbe einer in einer voranstehenden Druckeinheit bereits mit Farbe belegten Bedruckstoffbahn.These devices work in changing the position of the printing material web with an unchangeable web length, for which purpose technically and costly means for web storage and web displacement as well as the guidance and movement of the movement which can be moved into different positions are required. Additional roller contacts increase the risk of smearing the printing ink of a printing material web already coated with ink in a preceding printing unit.
Aus der DE 30 34 670 A1 ist ein Druckwerk, bestehend aus übereinander angeordneten Druckwerkzylindern, für eine Rollen-Rotationsdruckmaschine bekannt, in das eine zu bedruckende Bahn von einem aufsteigenden Bahnführungsabschnitt kommend über eine die Bahn umlenkende Leitwalze seitlich zwischen zwei Druckwerkzylindern einführbar ist, wobei die aufsteigende Bahn über die absenkbar ausgestaltete die Bahn umlenkende Leitwalze einen Zugang zu oberen Druckwerkzylindern ermöglicht.From DE 30 34 670 A1 a printing unit, consisting of printing unit cylinders arranged one above the other, is known for a web-fed rotary printing press, into which a web to be printed coming from an ascending web guide section can be inserted laterally between two printing unit cylinders via a guide roller deflecting the web, the ascending web via the guide roller deflecting the web allows access to upper printing unit cylinders.
Aus der EP 0 699 524 A2 ist eine Offsetdruckmaschine bekannt, dessen Zylinder und Funktionsgruppen jeweils von einem separaten Elektromotor angetrieben werden.An offset printing press is known from EP 0 699 524 A2, the cylinders and functional groups of which are each driven by a separate electric motor.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Veränderung der Bahnlage einer Bedruckstoffbahn gemäß dem Oberbegriff von Anspruch 1 zu schaffen, die kostengünstig ist und mit einfachen, wenig Platz benötigenden technischen Mitteln realisierbar ist.The invention has for its object to provide a device for changing the web position of a printing substrate web according to the preamble of claim 1, which is inexpensive and can be implemented with simple, space-saving technical means.
Die Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 realisiert.The object is achieved by the characterizing features of claim 1.
Mit Hilfe der einzeln motorisch angetriebenen Funktionsgruppen einer Rotationsdruckmaschine ist es problemlos möglich, ausgehend von einer Abwickeleinrichtung eine zusätzliche Bahnlänge zu fördern und mit dieser eine Bahnschlaufe an der jeweils gewünschten Stelle eines zu bedienenden Druckwerkes im Zusammenhang mit der Abwickelvorrichtung zu erzeugen und die Bahnschlaufe nach der Bedienung des Druckwerkes durch in Bahnlaufrichtung nachfolgende, die Bedruckstoffbahn fördernde Funktionsgruppen wieder zurückzubilden. In die Bahnschlaufe ist ein seitlich außerhalb der Bedruckstoffbahn am Gestell angelenkter Auftritt in einfacher Weise einschwenkbar. Zusätzliche Kontaktstellen der Bedruckstoffbahn mit Bahnführungselementen entstehen bis auf eine geringe drucklose Abstützung der Bahnschlaufe an Gestell- und Führungselementen nicht.With the help of the individually motor-driven functional groups of a rotary printing press, it is easily possible, starting from one To unwind an additional web length and use it to create a web loop at the desired location of a printing unit to be operated in connection with the unwinding device and to re-form the web loop after the printing unit has been operated by functional groups that follow in the web running direction and promote the printing material web. A step articulated laterally on the frame outside of the printing material web can be pivoted into the web loop in a simple manner. There are no additional contact points of the printing material web with web guiding elements apart from a slight pressure-free support of the web loop on frame and guiding elements.

Jedes Doppeldruckwerk 1; 2 besteht aus zwei Druckwerken 4; 5 bzw. 6; 7 mit jeweils einem außen liegenden Formzylinder 8 bis 11 und einem innen liegenden Übertragungszylinder 12 bis 15. Zwischen den Übertragungszylindern 12; 13 bzw. 14; 15 eines Doppeldruckwerkes 1; 2 wird im indirekten Druck jeweils eine Bedruckstoffbahn 16; 17 in einer Druckstelle gleichzeitig beiderseitig mit je einer Farbe belegt. Während ein der Druckeinheit 3 in Bahnlaufrichtung vorgeordnetes, mit einer gegen eine angetriebene Walze anstellbaren Preßwalze ausgestattetes Einzugwerk 18; 19 einzeln motorisch angetrieben ist, ist dies wahlweise für jeden Form- und Übertragungszylinder 8 bis 11; 12 bis 15, jedes Druckwerkes 4 bis 7 oder jedes Doppeldruckwerkes 1; 2 praktizierbar, wobei im ersten Fall die Zylinder nicht untereinander, im zweiten Fall jeweils der Formzylinder und der Übertragungszylinder 8 und 12; 9 und 13; 10 und 14; 11 und 15 paarweise und im dritten Fall die vier Zylinder des Doppeldruckwerkes 1; 2 in formschlüssiger Antriebsverbindung stehen.Fig. 1 shows one with two superimposed double printing units 1; 2 H-printing unit equipped in a horizontal cylinder arrangement 3. Each double printing unit 1; 2 consists of two printing units 4; 5 or 6; 7, each with an outside forme cylinder 8 to 11 and an inside transfer cylinder 12 to 15. Between the transfer cylinders 12; 13 or 14; 15 of a double printing unit 1; 2, a printing material web 16; 17 simultaneously coated with one color on both sides in a printing point. While an upstream of the printing unit 3 in the web running direction, with a feed roller 18 which can be adjusted against a driven roller; 19 is individually driven by a motor, this is optionally for each forme and transfer cylinder 8 to 11; 12 to 15, each printing unit 4 to 7 or each double printing unit 1; 2 practicable, in the first case the cylinders not with each other, in the second case the forme cylinder and the transfer cylinder 8 and 12; 9 and 13; 10 and 14; 11 and 15 in pairs and in the third case the four cylinders of the double printing unit 1; 2 are in a positive drive connection.
Analog zu den Einzugwerken 18; 19, Zylindern bzw. Druckwerken 4 bis 7 bzw. Doppeldruckwerken 1; 2 sind nicht dargestellt von einer Abwickeleinrichtung ausgehend alle nachfolgenden, die Bedruckstoffbahn 16; 17 in fester Einspannung transportierenden Funktionsgruppen unabhängig voneinander einzeln antreibbar.Analogous to the Einzugwerke 18; 19, cylinders or printing units 4 to 7 or double printing units 1; 2 are not shown, starting from an unwinding device, all subsequent ones, the printing material web 16; 17 function groups transporting them in fixed clamping can be driven independently of one another.
Während jeweils das untere Druckwerk 4 bzw. 5 für einen Bedienenden von einem gestellfesten Laufsteg 20; 21 - beispielsweise für den Wechsel einer Druckform - frei zugänglich ist, wird jeweils das obere Druckwerk 6 bzw. 7 durch die sich in ihrer als Vollinie dargestellten Betriebslage befindende Bedruckstoffbahn 16; 17 verdeckt.While in each case the lower printing unit 4 or 5 for an operator of a fixed catwalk 20; 21 - for example for changing a printing form - is freely accessible, the upper printing unit 6 or 7 is in each case by the printing material web 16; 17 covered.
Um bezüglich der Bedruckstoffbahn 16 den Zugang zu dem oberen Druckwerk 6 zu ermöglichen, fördern bei stillstehendem oberen Doppeldruckwerk 2 alle in Bahnlaufrichtung einschließlich des Einzugwerkes 19 dem Doppeldruckwerk vorgeordneten Funktionsgruppen die Bedruckstoffbahn 16 in eine vor dem unteren Druckwerk 4 frei durchhängende, gestrichelt dargestellte Bahnschlaufe 22, die lediglich auf einem weiterhin die doppelseitige Farbbelegung der Bedruckstoffbahn 17 in dem unteren Doppeldruckwerk 1 ermöglichenden Stützelement 23 aufliegt. Ist die Bahnschlaufe 22 voll ausgebildet, wird ein von der Bedruckstoffbahn 16 seitlich am Gestell angelenkter Auftritt 24 gemäß strichpunktierter Darstellung quer zur Bedruckstoffbahn 16 in die Bahnschlaufe 22 geschwenkt, so daß von dem Auftritt die Bedienung des oberen Druckwerkes 6 erfolgen kann.In order to allow access to the upper printing unit 6 with respect to the printing material web 16, when the upper double printing unit 2 is at a standstill, all functional groups upstream of the double printing unit in the web running direction including the feeding unit 19 convey the printing material web 16 into a web loop 22, which is shown in dashed lines in front of the lower printing unit 4, which rests only on a support element 23 which further enables the double-sided color assignment of the printing material web 17 in the lower double printing unit 1. If the web loop 22 is fully formed, a step 24 hinged to the side of the frame by the printing material web 16 is pivoted into the web loop 22 transversely to the printing material web 16, as shown in dash-dot line, so that the upper printing unit 6 can be operated from the step.
Nach Abschluß der Bedienung am Druckwerk 6 wird der Auftritt 24 - beispielsweise durch einen druckmittelbetriebenen Arbeitszylinderzurückgeschwenkt und nachfolgend die Bahnschlaufe 22 mittels Antriebes des Doppeldruckwerkes 2 und diesem nachgeordneter bahnfördernder Funktionsgruppen ggf. im Zusammenwirken mit der Abwickelvorrichtung zurückgebildet.After the operation on the printing unit 6 has been completed, the appearance 24 is pivoted back, for example by a pressure medium-operated working cylinder, and the web loop 22 is subsequently reduced by means of the drive of the double printing unit 2 and this downstream web-promoting functional groups, possibly in cooperation with the unwinding device.
