Description

Die Erfindung betrifft eine Falzmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a folding machine according to the preamble of patent claim 1.

Eine solche Falzmaschine kommt in der Regel zum Erzeugen diverser, komplexer Druckprodukte zum Einsatz, da sie in der Lage ist, senkrecht zueinander stehende Falzbrüche zu erzeugen. Den beiden Schwertfalzwerken ist normalerweise ein Taschenfalzwerk vorgeschaltet, das zunächst eine oder mehrere parallele Falzungen eines Bogens durchführt. Danach folgen die beiden Schwertfalzwerke. Das erste Schwertfalzwerk falzt den Bogen senkrecht zu den Falzungen im Taschenfalzwerk. Das zweite Schwertfalzwerk falzt den Bogen senkrecht zu den Falzungen des ersten Schwertfalzwerks beziehungsweise parallel zu den Falzungen des Taschenfalzwerkes.Such a folding machine is usually used for producing diverse, complex printed products, since it is able to produce mutually perpendicular fold breaks. The two Schwertfalzwerken is usually preceded by a pocket folder, which initially performs one or more parallel folds of a bow. Then follow the two sword folders. The first knife folds the sheet perpendicular to the folds in the pocket folder. The second blade folder folds the sheet perpendicular to the folds of the first knife folder or parallel to the folds of the pocket folder.

Bei den bekannten gattungsgemäßen Falzmaschinen sind die Taschenfalzwerke, sowie die zwei Schwertfalzwerke starr und zueinander unverschiebbar angeordnet, wobei ggf. eine Messerwelle am ersten Schwertfalzwerk gelagert ist. Aus diesem Grund ist es erforderlich, den Bogenanschlag des ersten Schwertfalzwerkes abhängig von der Bogenlänge so einzustellen, dass die Bogenmitte immer auf Höhe der Falzlinie des zweiten Schwertfalzwerkes liegt. Bei der Falzung von kurzen Bögen liegt daher die nachlaufende Bogenkante des einlaufenden Bogens in Bogenlaufrichtung nach der hinteren Kante des Falzschwertes. Der Bogenweg ist daher relativ lang, wodurch die Arbeitsgeschwindigkeit der Falzmaschine verringert wird. Darüber hinaus ist es aufgrund der starren Anordnung der beiden Schwertfalzwerke zueinander nicht möglich, unterschiedliche außermittige Falzungen in dem zweiten Schwertfalzwerk durchzuführen.In the known generic folding machines the Taschenfalzwerke, and the two Schwertfalzwerke are rigid and mutually immovable, with possibly a knife shaft is mounted on the first sword folder. For this reason, it is necessary to set the sheet stop of the first sword folder depending on the sheet length so that the center of the sheet is always equal to the fold line of the second blade folder. When folding short sheets, therefore, the trailing sheet edge of the incoming sheet is in the sheet running direction to the rear edge of the folding blade. The sheet path is therefore relatively long, whereby the operating speed of the folding machine is reduced. In addition, it is not possible due to the rigid arrangement of the two Schwertfalzwerke each other to perform different eccentric folds in the second blade folder.

Die FR 1 207 587 A beschreibt eine Falzmaschine mit den Merkmalen des Oberbegriffs des Patentanspruchs 1, wobei keinem der beiden Falzwerke eine Messerwelle nachgeordnet ist.The FR 1 207 587 A describes a folding machine with the features of the preamble of claim 1, wherein neither of the two folders is a knife shaft downstream.

Der Erfindung liegt die Aufgabe zugrunde, mit konstruktiv einfachen Mitteln eine vielseitige Falzmaschine mit hoher Arbeitsgeschwindigkeit zu schaffen.The invention has for its object to provide a versatile folding machine with high working speed with structurally simple means.

Diese Aufgabe wird durch eine Falzmaschine mit den Merkmalen des Patentanspruchs 1 gelöst. Eine vorteilhafte Weiterbildung der erfindungsgemäßen Falzmaschine ist Gegenstand des Patentanspruchs 2.This object is achieved by a folding machine with the features of claim 1. An advantageous development of the folding machine according to the invention is the subject of claim 2.

Dadurch, dass das zweite Schwertfalzwerk relativ zum ersten Schwertfalzwerk verschoben werden kann, kann das Spektrum der möglichen Falzmuster der Falzmaschine erweitert werden. Es können beispielsweise außermittige Falzungen, wie zum Beispiel ein Wickelfalz oder Zick-Zackfalz in dem zweiten Schwertfalzwerk erzeugt werden.The fact that the second sword folder can be moved relative to the first sword folder, the spectrum of possible folding patterns of the folding machine can be extended. For example, eccentric folds, such as a winding fold or zig-zag fold, may be produced in the second knife folder.

Darüber hinaus kann durch die Möglichkeit der Verschiebung des zweiten Schwertfalzwerkes das Leistungspotential einer Falzmaschine voll ausgeschöpft werden. Dies ist dann der Fall, wenn ein aus einem Taschenfalzwerk einlaufender Bogen nur so weit unter das erste Falzschwert läuft, bis die Hinterkante des ersten Falzschwertes die nachlaufende Bogenkante bei der Falzung erfassen kann. Würde der Bogen weiter unter das erste Falzschwert laufen, müsste für einen Falzzyklus die für den zusätzlichen Verfahrweg benötigte Zeit mit einbezogen werden. Bei der erfindungsgemäßen Falzmaschine wird zur Optimierung der Falzgeschwindigkeit daher der zu falzende Bogen nur so weit unter das erste Falzschwert verfahren, bis die Hinterkante des ersten Falzschwertes und die Hinterkante des Bogens übereinander liegen. Die Falzlinie des zweiten Falzschwertes wird dann durch Verfahren des zweiten Schwertfalzwerkes in Flucht zur Bogenmitte gebracht.In addition, the power potential of a folding machine can be fully exploited by the possibility of shifting the second sword folder. This is the case when an incoming from a pocket folder arc runs only so far under the first folding blade until the trailing edge of the first folding blade can detect the trailing edge of the sheet in the fold. If the sheet continued to run under the first folding blade, the time required for the additional travel would have to be included for a folding cycle. In the folding machine according to the invention, therefore, the sheet to be folded is moved only so far under the first folding blade to optimize the folding speed until the trailing edge of the first folding blade and the trailing edge of the sheet are one above the other. The fold line of the second folding blade is then brought by the process of the second sword folder in alignment to the center of the sheet.

Da dem ersten Schwertfalzwerk ein Messerwellenpaar nachgeordnet ist, das in dem zweiten Schwertfalzwerk gelagert ist, wird gewährleistet, dass ein auf die Schwertmitte des zweiten Falzschwertes eingestelltes Schneidwerkzeug auf dem Messerwellenpaar immer exakt zur Schwertlinie stehen bleibt. Wäre das Messerwellenpaar nicht in dem zweiten Schwertfalzwerk gelagert, sondern wie üblich in dem ersten Schwertfalzwerk, würden sich die Schwertlinie und die Messerlinie bei Verfahren des zweiten Schwerfalzwerkes relativ zueinander bewegen und die Messer müssten um den Verfahrweg manuell korrigiert werden.Since the first sword folding a knife shaft pair is arranged downstream, which is mounted in the second sword folder, it is ensured that a set on the sword center of the second folding blade cutting tool on the knife shaft pair always remains exactly to the sword line. If the pair of knife shafts were not stored in the second blade folder, but as usual in the first blade folder, the blade line and the blade line would move relative to each other during the second heavy folder process and the blades would have to be manually corrected for the travel distance.

Bei der bevorzugten Ausführungsform ist das zweite Schwertfalzwerk in eine Servicestellung aus der Falzmaschine herausfahrbar, in der die Messerwellen frei zugänglich sind. Hierdurch wird ein Ein- beziehungsweise Ausbau der schweren Messerwellen erleichtert.In the preferred embodiment, the second sword folder is moved out into a service position from the folding machine, in which the blade shafts are freely accessible. As a result, an installation or removal of heavy knife shafts is facilitated.

Die in den Fig. 1 bis 5 gezeigte Falzmaschine 10 weist ein erstes Schwertfalzwerk 12 auf, das in Bogenlaufrichtung BL einem Taschenfalzwerk (nicht gezeigt) nachgeordnet ist. Ein aus dem Taschenfalzwerk einlaufender Bogen 20 kommt auf einer Bogenauflageeinrichtung (nicht gezeigt) in einer Bogenauflageebene BE1 zum Liegen, wobei er mit seiner voreilenden Kante 18 an einem quer zur Bogenlaufrichtung BL angeordneten Bogenanschlag 18 anschlägt, der in Bogenlaufrichtung BL verstellbar ist. Oberhalb der Bogenauflageebene BE1 befindet sich auf bekannte Weise ein Falzschwert 16, das eine senkrechte Hubbewegung durchführt, um den Bogen 20 zwischen zwei unterhalb der Bogenauflageebene BE1 vorgesehene Falzwalzen (nicht gezeigt) einzuschlagen. Nach Durchlauf durch die Falzwalzen wird der Bogen senkrecht zur Bogenlaufrichtung BL aus dem ersten Schwertfalzwerk 12 durch eine Bogenabgabeeinrichtung 36 zu einem zweiten Schwertfalzwerk 14 befördert, das dem ersten Schwertfalzwerk 12 nachgeordnet ist. Wie es in den Fig. 1 und 2 schematisch gezeigt ist, kommt der Bogen 20 als gefalzter Bogen 22 in der Bogenauflageebene BE2 einer zweiten Bogenauflageeinrichtung (nicht gezeigt) des zweiten Schwertfalzwerkes 14 zum Liegen. Oberhalb der Bogenauflageebene BE2 ist ein zweites Falzschwert 24 angeordnet, dessen Schwertlinie senkrecht zur Schwertlinie des ersten Falzschwertes 16 verläuft. Unterhalb des zweiten Falzschwertes 24 ist ein Falzwalzenpaar 26 angeordnet, in das der gefalzte Bogen 22 durch das Falzschwert 24 eingeschlagen wird. Unterhalb des Falzwalzenpaares 26 sind weitere Falzwalzen 28 zur Beförderung des Bogens 22 aus dem zweiten Schwertfalzwerk 14 vorgesehen. Wie es in den Fig. 1 und 2 zu erkennen ist, ist das zweite Schwertfalzwerk 14 in einem Rahmen 30 angeordnet, an dessen Unterseite Führungen 32 vorgesehen sind, die auf Führungsschienen 34 laufen, die senkrecht zur Schwertlinie des zweiten Falzschwertes 24, das heißt senkrecht zur Bogenauslaufrichtung des aus der ersten Bogenabgabeeinrichtung 36 des ersten Schwertfalzwerks 12 auslaufenden Bogens angeordnet sind.The in the Fig. 1 to 5 Folding machine 10 shown has a first blade folder 12, which is arranged in the sheet running direction BL a pocket folder (not shown). An incoming from the Taschenfalzwerk sheet 20 comes on a sheet support device (not shown) in a sheet support plane BE1 to lie, where he with its leading edge 18 abuts a sheet stop 18 arranged transversely to the direction of sheet travel BL, which is adjustable in sheet travel direction BL. Above the sheet support plane BE1 is located in a known manner a folding blade 16 which performs a vertical lifting movement to beat the sheet 20 between two provided below the sheet support plane BE1 folding rollers (not shown). After passing through the folding rollers, the sheet is conveyed perpendicularly to the sheet running direction BL from the first blade folder 12 through a sheet delivery device 36 to a second blade folder 14, which is the first sword folding unit 12 downstream. As it is in the Fig. 1 and 2 is shown schematically, the sheet 20 comes as a folded sheet 22 in the sheet support plane BE2 a second sheet support device (not shown) of the second sword folder 14 to lie. Above the sheet support plane BE2 a second folding blade 24 is arranged, the sword line is perpendicular to the sword line of the first folding blade 16. Below the second folding blade 24, a folding roller pair 26 is arranged, in which the folded sheet 22 is hammered by the folding blade 24. Below the Falzwalzenpaares 26 more folding rollers 28 are provided for conveying the sheet 22 from the second blade folder 14. As it is in the Fig. 1 and 2 can be seen, the second blade folder 14 is disposed in a frame 30, on the underside guides 32 are provided which run on guide rails 34 which are perpendicular to the sword line of the second folding blade 24, that is perpendicular to the sheet discharge direction of the first sheet delivery device 36 of first sword folder 12 expiring bow are arranged.

Aufgrund der Führungen 32 und der Führungsschienen 34 kann das zweite Schwertfalzwerk 14 senkrecht zur Bogenauslaufrichtung horizontal verfahren werden, wie dies durch den Doppelpfeil DP angedeutet ist.Due to the guides 32 and the guide rails 34, the second blade folder 14 can be moved horizontally perpendicular to the sheet discharge direction, as indicated by the double arrow DP.

Die Fig. 1 zeigt die Positionen des zweiten Schwertfalzwerks 14 zur Falzung eines relativ kurzen Bogens 20. Hierzu wird der Bogenanschlag 18 so eingestellt, dass die nacheilende Kante des Bogens 20 und die Hinterkante des Falzschwertes 16 übereinander liegen. Das zweite Schwertfalzwerk 14 ist so verfahren, dass die Schwertlinie SL des zweiten Falzschwertes 24 auf Höhe der Bogenmitte BM des Bogens 20 liegt. Diese Einstellung des Bogenanschlags 18 und des zweiten Schwertfalzwerks 14 ermöglicht es, dass der Bogen 20 nur so weit in das erste Schwertfalzwerk 12 eingefahren wird, dass seine gesamte Länge von dem Falzschwert 16 beaufschlagt werden kann. Dies ist dann der Fall, wenn die hintere Kante des ersten Falzschwertes 16 und die nacheilende Kante des Bogens 20 übereinander liegen.The Fig. 1 shows the positions of the second blade folder 14 for folding a relatively short sheet 20. For this purpose, the sheet stop 18 is set so that the trailing edge of the sheet 20 and the trailing edge of the folding blade 16 are superimposed. The second sword folder 14 is moved so that the sword line SL of the second folding blade 24 is at the level of the arc center BM of the sheet 20. This setting of the sheet stopper 18 and the second blade folder 14 makes it possible that the sheet 20 is retracted only so far in the first blade folder 12, that its entire length can be acted upon by the folding blade 16. This is the case when the trailing edge of the first folding blade 16 and the trailing edge of the sheet 20 are superimposed.

Fig. 2 zeigt die Einstellung des Bogenanschlags 18 des zweiten Schwertfalzwerks 14 für die Bearbeitung eines langen Bogens 20. Auch hier ist der Bogenanschlag 18 so eingestellt, dass die nacheilende Kante des Bogens 20 auf Höhe der hinteren Kante des ersten Falzschwertes 16 liegt. Das zweite Schwertfalzwerk 14 ist so verfahren, dass die Schwertlinie SL mit der Bogenmitte BM übereinstimmt. Fig. 2 shows the setting of the sheet stop 18 of the second blade folder 14 for the processing of a long sheet 20. Again, the sheet stop 18 is set so that the trailing edge of the sheet 20 is equal to the rear edge of the first folding blade 16. The second blade folder 14 is moved so that the sword line SL coincides with the arc center BM.

In den Fig. 3 bis 5 sind zum Zweck einer besseren Übersichtlichkeit nur Elemente unterhalb der Bogenauflageebene BE1 und BE2 gezeigt. Wie es in den Fig. 3 und 5 zu erkennen ist, sind zwei Führungsschienen 34a, 34b parallel und im Abstand zueinander angeordnet, auf denen der Rahmen 30 des zweiten Schwertfalzwerkes 14 mit Hilfe der Führungen 32 geführt ist. In dem zweiten Schwertfalzwerk 14 ist der Bogenabgabeeinrichtung 36 gegenüberliegend ein Messerwellenpaar 38 in dem Rahmen 30 gelagert. Auf den Messerwellen des Messerwellenpaares 38 sind auf bekannte Weise Schneid- oder Perforierwerkzeuge angebracht. Ein aus dem ersten Schwertfalzwerk 12 auslaufender Bogen 22 wird zwischen die Messerwellen des Messerwellenpaares 38 hindurchgeführt, bevor er auf die Bogenauflageeinrichtung (nicht gezeigt) des zweiten Schwertfalzwerkes 14 aufgelegt wird. Wie es in Fig. 5 gezeigt ist, kann das zweite Schwertfalzwerk 14 entlang der Führungsschienen 34a, 34b so weit aus der Falzmaschine 10 verfahren werden, bis das Messerwellenpaar 38 von außen zugänglich ist. Wenn sich das Schwertfalzwerk 14 in dieser Serviceposition befindet, ist ein leichter Ein- beziehungsweise Ausbau des Messerwellenpaares 38 aus dem Rahmen 30 möglich.In the Fig. 3 to 5 For the sake of clarity, only elements below the sheet support plane BE1 and BE2 are shown. As it is in the Fig. 3 and 5 can be seen, two guide rails 34a, 34b are arranged parallel to and at a distance from each other, on which the frame 30 of the second sword folder 14 by means of the guides 32 is guided. In the second sword folder 14 of the sheet delivery device 36 opposite a pair of knife shafts 38 is mounted in the frame 30. On the knife shafts of the knife shaft pair 38 cutting or perforating tools are mounted in a known manner. An expiring from the first sword folder 12 sheet 22 is passed between the blade shafts of the pair of knife shafts 38 before it is placed on the sheet support device (not shown) of the second blade folder 14. As it is in Fig. 5 is shown, the second sword folder 14 along the guide rails 34a, 34b so far from the folding machine 10 are moved until the pair of knife shafts 38 is accessible from the outside. If the sword folder 14 is in this service position, an easy installation or removal of the cutter shaft pair 38 from the frame 30 is possible.

Das Verfahren des zweiten Schwertfalzwerkes 14 entlang der Führungsschienen 34a, 34b kann manuell oder motorisch über bekannte Führungs- beziehungsweise Antriebselemente realisiert werden.The method of the second sword folder 14 along the guide rails 34a, 34b can be realized manually or by motor via known guide or drive elements.
