Description

Die Erfindung betrifft ein Kreuzbruchmodul sowie eine Falzmaschine mit den Merkmalen der Oberbegriffe der Patentansprüche 1 bzw. 2.The invention relates to a cross-rupture module and a folding machine with the features of the preambles of claims 1 and 2 respectively.

Aus der FR 1.207. 587 ist eine Falzmaschine bekannt, die ein Kreuzbruchmodul aufweist, das ein sich in Kreuzbrucheinlaufrichtung eines Bogens erstreckendes Kreuzbruch-Falzschwert umfasst, das einen einlaufenden und mit seiner voreilenden Kante an einer Endanschlageinrichtung anliegenden Bogen in den Falzwalzenspalt eines Falzwalzenpaares einschlägt, das unter dem Kreuzbruch-Falzschwert angeordnet ist, wodurch der Bogen gefalzt wird. Der gefalzte Bogen wird dann senkrecht zur Kreuzbrucheinlaufrichtung aus dem Kreuzbruchmodul einem Dreibruchmodul zugeführt, das ein sich in Dreibrucheinlaufrichtung erstreckendes Dreibruch-Falzschwert umfasst, das den aus dem Kreuzbruchmodul kommenden Bogen in zwei unterhalb des Dreibruch-Falzschwertes angeordnete Falzwalzen einschlägt, wodurch der Bogen senkrecht zu der Falzung im Kreuzbruchmodul noch einmal gefalzt wird.From the FR 1.207. 587 a folding machine is known which comprises a cross-rupture module, which comprises a cross-fold in the direction of cross-arch extending cross-fold blade, which an incoming and with its leading edge abuts a Endanschlageinrichtung sheet in the Falzwalzenspalt a pair of folding rolls arranged under the cross-folding blade is, whereby the bow is folded. The folded sheet is then fed perpendicularly to the direction of the cross-fold from the cross-rupture module to a three-prong module comprising a three-pronged folding blade extending in the three-prong direction, which strikes the sheet coming from the cross-rupture module into two folding rollers arranged below the three-pronged sheet, whereby the sheet is perpendicular to the sheet Fold in the cross-rupture module is folded again.

Zur Anpassung an die Bogenlänge sind die Falzwalzen und das Falzschwert des Dreibruchmoduls quer zur Dreibrucheinlaufrichtung verstellbar, damit ein in das Dreibruchmodul einlaufender Bogen entlang seiner sich in Dreibrucheinlaufrichtung verlaufenden Mittellinie gefalzt werden kann.In order to adapt to the arc length, the folding rollers and the folding blade of the three-prong module are adjustable transversely to the three-prong input direction, so that a sheet entering the tri-unit module can be folded along its center line running in the three-prong input direction.

Die Länge des in Bogeneinlaufrichtung festgelegten Falzschwerts des Kreuzbruchmoduls ist auf die Länge des größten zu falzenden Bogens ausgelegt, so dass sich das Falzschwert immer im Wesentlichen über das ganze Kreuzbruchmodul erstreckt. Auch wenn ein kurzer Bogen in dem Kreuzbruchmodul gefalzt wird, muss sich dieser bis zum Anschlag an die Endanschlageinrichtung unter der gesamten Länge des Falzschwertes bewegen. Der Weg des Bogen, den der Bogen unter dem Falzschwert zurücklegen muss, ist somit sehr weit, so dass das Falzschwert erst relativ spät ausgelöst werden kann. Hierdurch wird jedoch die Arbeitsgeschwindigkeit einer Falzmaschine beschränkt.The length of the folded blade of the cross-rupture module determined in the sheet feed direction is designed for the length of the largest sheet to be folded, so that the folding blade always extends essentially over the entire cross-rupture module. Even if a short arc is folded in the cross-rupture module, this must move all the way to the stop against the Endanschlageinrichtung under the entire length of the folding blade. The path of the arc, which the bow must cover under the folding sword, is thus very far, so that the folding sword can be triggered relatively late. As a result, however, the operating speed of a folding machine is limited.

Aus der DE 101 19 415 A1 ist ein Kreuzbruchmodul bekannt, das anschließend an den Bogenauslauf des Kreuzbruchmoduls eine Bogenauflageeinrichtung aufweist, die von mehreren im Abstand zueinander angeordneten Transportbändern gebildet wird, die eine gemeinsame einlaufseitig angetriebene Bandwalze sowie eine dem Einlauf abgewandte Bandwalze umlaufen. Die oberen Trums der Transportbänder bilden eine Transportebene. Ein oberhalb der Transportebene angeordnetes Kreuzbruch-Falzschwert dient zum Einschlagen eines an einem Endanschlag anliegenden Bogens zwischen zwei Falzwalzen, die unterhalb der Bogenauflageeinrichtung angeordnet sind. Der Bogen wird beim Einlaufen in das Kreuzbruchmodul zu dem Endanschlag durch eine Niederhalteeinrichtung niedergehalten. Zur Anpassung an die Bogenlänge ist die Endanschlageinrichtung in Bogeneinlaufrichtung verstellbar. Das Falzschwert erstreckt sich jedoch wie bei dem aus der FR 1.207. 587 bekannten Kreuzbruchmodul im Wesentlichen über das ganze Kreuzbruchmodul, so dass ein kurzer Bogen auch bei diesem Kreuzbruchmodul einen relativ langen Weg unter dem Falzschwert zurücklegen muss, wodurch die Arbeitsgeschwindigkeit beschränkt wird.From the DE 101 19 415 A1 a cross-rupture module is known, which subsequently comprises a sheet support device on the sheet outlet of the cross-rupture module, which is formed by a plurality of mutually spaced conveyor belts, which rotate a common intake side driven belt roller and a belt drum facing away from the inlet. The upper runs of the conveyor belts form a transport plane. A cross-folded folding blade arranged above the transport plane serves for driving in a sheet resting against an end stop between two folding rollers which are arranged below the sheet-receiving device. The bow is held down when entering the cross-rupture module to the end stop by a hold-down device. To adapt to the arc length, the Endanschlageinrichtung is adjustable in the sheet inlet direction. The folding sword, however, extends as in the from the FR 1.207. 587 known cross-break module substantially over the entire cross-break module, so that a short arc must cover a relatively long path under the folding blade also in this cross-break module, whereby the operating speed is limited.

Aus der DE 4 329 688 C1 ist eine Falzschwertanordnung für Schwertfalzwerke bekannt, die ein in Bogeneinlaufrichtung verstellbares Falzschwert aufweist.From the DE 4 329 688 C1 a folding blade arrangement for Schwertfalzwerke is known, which has an adjustable in the sheet feed direction folding blade.

Der Erfindung liegt die Aufgabe zugrunde, mit einfachen Mitteln ein Kreuzbruchmodul zu schaffen, das eine hohe Arbeitsgeschwindigkeit einer Falzmaschine ermöglicht.The invention has for its object to provide a simple means a cross-break module, which allows a high operating speed of a folding machine.

Diese Aufgabe wird durch ein Kreuzbruchmodul mit den Merkmalen des Patentanspruchs 1 gelöst. Eine Falzmaschine, in der das erfindungsgemäße Kreuzbruchmodul eingesetzt wird, ist Gegenstand des Patentanspruchs 2.This object is achieved by a cross-rupture module having the features of patent claim 1. A folding machine in which the cross-fold module according to the invention is used, is the subject of claim 2.

Bei dem erfindungsgemäßen Kreuzbruchmodul ist sowohl die Endanschlageinrichtung als auch das Kreuzbruch-Falzschwert in Kreuzbrucheinlaufrichtung verstellbar. Hierdurch ist es möglich, den in den Kreuzbruch einlaufenden Bogen so zu positionieren, dass er in dem Dreibruch längs seiner in Dreibrucheinlaufrichtung verlaufenden Mittellinie oder einer anderen Falzlinie (z.B. für Altar oder Zick-Zackfalz) gefalzt werden kann. Das Kreuzbruch-Falzschwert kann so verstellt werden, dass sein hinteres Ende über der nacheilenden Kante des Bogens liegt. Hierdurch ist der Weg, den der Bogen unter dem Kreuzbruch-Falzschwert zurücklegen muss, minimal. Das Kreuzbruch-Falzschwert kann daher früh ausgelöst werden. Dies ermöglicht eine hohe Arbeitsgeschwindigkeit einer Falzmaschine.In the case of the cross-rupture module according to the invention, both the end stop device and the cross-rupture folding blade can be adjusted in the direction of cross-fold entry. This makes it possible to position the sheet entering the cross-fold so that it can be folded in the three-prong along its center line running in the three-prong direction or another fold line (eg for altar or zig-zag fold). The cross-fold can be adjusted so that its rear end lies over the trailing edge of the arch. As a result, the path that the arc must travel under the cross-fold blade is minimal. The Crossbreadfolding sword can therefore be triggered early. This allows a high operating speed of a folding machine.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der beigefügten Zeichnungen beschrieben. Es zeigen

  • Fig.1 schematisch eine Seitenansicht der Hauptbauelemente eines Kreuzbruchmoduls einer Falzmaschine, das zur Falzung eines langen Bogens eingestellt ist,

An embodiment of the invention will be described below with reference to the accompanying drawings. Show it
  • 1 schematically shows a side view of the main components of a cross-rupture module of a folding machine, which is set for folding a long sheet,
  • 2 shows the cross-rupture module of Fig. 1 in a setting for folding a short bow.

Das Kreuzbruchmodul 10 einer Falzmaschine weist wie das aus der DE 101 19 415 A1 bekannte Kreuzbruchmodul mehrere parallel in seitlichem Abstand zueinander angeordnete Transportbänder 12 auf, die eine dem Bogenauslauf des Kreuzbruchmoduls 10 zugewandte, angetriebene Bandwalze 14 und ein dem Kreuzbruchmodul 10 abgewandte Bandwalze 16 umlaufen. Die oberen Trums 13 der nebeneinander angeordneten Transportbänder 12 liegen in einer Transportebene TE.The cross-rupture module 10 of a folding machine has like that from the DE 101 19 415 A1 Known Kreuzbruchmodul several parallel spaced laterally spaced conveyor belts 12, which rotate around the sheet outlet of the cross-break module 10, driven belt roller 14 and the cross-break module 10 facing away from the belt roller 16. The upper strands 13 of the juxtaposed conveyor belts 12 lie in a transport plane TE.

Oberhalb der Transportebene TE ist eine Niederhalteeinrichtung 18 angeordnet, durch die ein in Kreuzbrucheinlaufrichtung KB einlaufender Bogen niedergehalten wird, bis er an einem in Kreuzbrucheinlaufrichtung KB verstellbaren Endanschlag 24 anschlägt. Die Niederhalteeinrichtung 18 wird von wenigstens zwei in seitlichem Abstand parallel zueinander angeordneten, sich in Kreuzbrucheinlaufrichtung KB erstreckenden Niederhalteleisten 20 gebildet, an deren Unterseite Bürsten 22 angeordnet sind, die den einlaufenden Bogen niederhalten und auch eine seitliche Verschiebung des einlaufenden Bogens verhindern.Above the transport plane TE, a hold-down device 18 is arranged, by means of which a sheet entering the cross-fold entry direction KB is held down until it abuts against an end stop 24 which can be adjusted in the direction of the cross-fold entry direction KB. The hold-down device 18 is formed by at least two laterally spaced parallel, extending in Kreuzbrucheinlaufrichtung KB hold-down 20, at the bottom brushes 22 are arranged to hold down the incoming sheet and also prevent lateral displacement of the incoming sheet.

In der Mitte des Kreuzbruchmoduls 10 ist oberhalb der Transportebene TE ein sich in Kreuzbrucheinlaufrichtung erstreckendes Kreuzbruch-Falzschwert 26 angeordnet, durch das ein Bogen durch die Transportebene TE hindurch zwischen ein Falzwalzenpaar (nicht gezeigt) eingeschlagen wird, durch die der Bogen gefalzt wird. Anschließend an das Falzwalzenpaar kann ein Messerwalzenpaar (nicht gezeigt) angeordnet sein.In the middle of the cross-rupture module 10 above the transport plane TE is a cross-fold directional folding blade 26 extending in Kreuzbrucheinlaufrichtung is arranged, through which a sheet through the transport plane TE between a pair of folding rollers (not shown) is taken, folded by the bow becomes. Subsequent to the folding roller pair, a knife roller pair (not shown) may be arranged.

Ein in dem Kreuzbruchmodul 10 gefalzter Bogen 10 wird senkrecht zu der Kreuzbrucheinlaufrichtung KB in einer Dreibrucheinlaufrichtung DB in einen Dreibruch befördert, der in Fig. 1 und 2 durch sein Dreibruch-Falzschwert 28 angedeutet wird.A folded in the cross-break module 10 sheet 10 is conveyed perpendicular to the Kreuzbrucheinlaufrichtung KB in a Dreibrucheinlaufrichtung DB in a triplet, which is indicated in Fig. 1 and 2 by its three-way folding blade 28.

Sowohl das Kreuzbruch-Falzschwert 26 als auch der Endanschlag 24 sind in Kreuzbrucheinlaufrichtung durch geeignete Antriebe oder manuell verstellbar, wie dies durch die Doppelpfeile angedeutet ist.Both the cross-fold blade 26 and the end stop 24 are in Kreuzbrucheinlaufrichtung by suitable drives or manually adjustable, as indicated by the double arrows.

Fig. 1 zeigt die Einstellung des Kreuzbruch-Falzschwerts 26 und des Endanschlag 24 zur Falzung eines langen Bogens 30 mit der Länge L1. Der Endanschlag 24 ist so eingestellt, dass die in Dreibrucheinlaufrichtung DB verlaufende, in der Falzschwertebene FE des Dreibruch-Falzschwertes 28 liegende Mittellinie oder eine andere Falzlinie des Bogens 30 auf Höhe des Dreibruch-Falzschwertes 28 liegt, so dass der Bogen 30 anschließend an die Falzung in dem Kreuzbruchmodul 10 durch das Dreibruch-Falzschwert 28 in dem Dreibruch entlang dieser Mittelinie oder anderen Falzlinie gefalzt wird.Fig. 1 shows the setting of the cross-fold blade 26 and the end stop 24 for folding a long sheet 30 with the length L1. The end stop 24 is adjusted so that the center line running in the three-printhead feed direction DB and lying in the folding level FE of the three-prong folding bar 28 or another fold line of the sheet 30 is at the level of the three-prong folding bar 28, so that the sheet 30 adjoins the fold in the cross-rupture module 10 is folded by the tri-fold rollover blade 28 in the tristate along this centerline or other fold line.

Das Kreuzbruch-Falzschwert 26 ist so eingestellt, dass sein stromaufwärtiges, d.h. hinteres, dem Bogeneinlauf des Kreuzbruchmoduls 10 zugewandtes Ende 27 oberhalb der nacheilenden Bogenkante eines einlaufenden Bogens 30 liegt. Der Weg des Bogens 30, den er unter dem Kreuzbruch-Falzschwert 26 zurücklegen muss, entspricht somit lediglich seiner Bogenlänge L1.The cross-fold knife 26 is set so that its upstream, i. behind, the sheet inlet of the cross-rupture module 10 facing end 27 above the trailing edge of an incoming sheet bow 30 lies. The path of the arc 30, which he must cover under the cross-folding sword 26, thus corresponds only to its arc length L1.

In Fig. 2 sind der Endanschlag 24 und das Kreuzbruch-Falzschwert 26 auf die gleiche Weise zur Falzung eines kurzen Bogens 32 mit einer Länge L2 so eingestellt , dass die in Dreibrucheinlaufrichtung verlaufende Mittellinie des Bogens 32 auf Höhe des Dreibruch-Falzschwertes 28 liegt und das hintere, dem Bogeneinlauf des Kreuzbruchmoduls 10 zugewandte Ende 27 des Kreuzbruch-Falzschwertes 26 oberhalb der nacheilenden Bogenkante eines einlaufenden Bogens 32 liegt. Der Weg des Bogens 32, den er unter dem Kreuzbruch-Falzschwert 26 zurücklegen muss, entspricht somit der kurzen Bogenlänge L2.In Fig. 2, the end stop 24 and the cross-fold blade 26 are set in the same manner for folding a short sheet 32 with a length L2 that the running in Drerupucheinlaufrichtung center line of the sheet 32 is at the level of the three-way folding blade 28 and the rear, the sheet inlet of the cross-rupture module 10 facing the end 27 of the cross-folded folding blade 26 above the trailing edge of an incoming arch sheet 32 is located. The path of the bow 32, which he must cover under the cross-folding sword 26, thus corresponds to the short arc length L2.
