Description

Die Erfindung betrifft eine Vorrichtung zum Positionieren von vorzugsweise in einer Kombifalzmaschine bewegten blattförmigen Gegenständen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for positioning of sheet-like objects preferably moved in a combination folding machine according to the preamble of claim 1.

Bei kombinierten Taschenschwertfalzmaschinen, so genannten Kombifalzmaschinen, werden die Parallelbrüche in einer ersten Falzstation im Taschenfalzprinzip gefalzt, während die nachfolgenden Kreuzbrüche mit einem vertikal arbeitenden Falzschwert ausgeführt werden. Hierzu werden die gefalzten Bogen nach dem Parallelbruchausgang zu einer Kreuzbruchstation mittels Transportbändern schlupffrei transportiert. Um einen tatsächlich schlupffreien Transport zu gewährleisten, muss das transportierte flächige Gut niedergehalten und vertikal auf das Transportband gedrückt werden. Zur Erzeugung der hierzu erforderlichen vertikalen Anpresskraft werden sowohl Belastungskugeln als auch Führungsrollen eingesetzt. Derartige Belastungskugelsysteme sind beispielsweise aus dem deutschen Gebrauchsmuster DE 84 06 391 bekannt. In der letzten Zeit hat sich jedoch der Einsatz von Führungsrollen vermehrt durchgesetzt, die beispielsweise im deutschen Gebrauchsmuster DE 93 04 281 beschrieben sind. Diese weisen gegenüber dem Belastungskugelsystem besondere Vorteile auf, die beispielsweise darin bestehen, dass mit Führungsrollen eine spurgenaue Bogenführung erreicht werden kann.In combined pocket sword folding machines, so-called combination folding machines, the parallel breaks are folded in a first folding station in Taschenfalzprinzip, while the subsequent cross fractures are performed with a vertical folding blade. For this purpose, the folded sheets are transported after the parallel break output to a cross-break station by means of conveyor belts without slip. In order to ensure a truly slip-free transport, the transported flat material must be held down and pressed vertically onto the conveyor belt. To generate the vertical contact force required for this purpose, both load balls and guide rollers are used. Such load ball systems are for example from the German utility model DE 84 06 391 known. Recently, however, the use of guide rollers has increasingly prevailed, for example, in the German utility model DE 93 04 281 are described. These have particular advantages over the load ball system, which are, for example, that with guide rollers a true-to-sheet bowing can be achieved.

Zur exakten Falzung im Messerfalzwerk ist es notwendig, dass die dem Kreuzbruchanschlag am nächsten liegende Führungsrolle exakt positioniert ist, das heißt also, dass der Bogen "frei" zwischen dem Vorderkantenanschlag und der Führungsrolle liegt. Um dies zu gewährleisten, muss die Führungsrolle so positioniert werden, dass sich die Rolle gerade noch dreht und weder auf der Bogenhinterkante noch direkt auf dem Falzbogen steht. Eine derartige Vorrichtung ist aus der deutschen Gebrauchsmusterschrift DE 299 04 757 bekannt. Hierin wird eine Vorrichtung zum Niederhalten und Belasten von bewegten blattförmigen Gegenständen vorgeschlagen, bei der zum Niederhalten der Gegenstände eine oder mehrere Führungsrollen vorgesehen sind. Zur genauen Positionierung der Führungsrollen ist wenigstens eine dieser Führungsrollen mit einer Markierung ausgestattet.For exact folding in the knife folding, it is necessary that the guide roller closest to the cross-rupture stopper is positioned exactly, that is, so that the sheet is "free" between the leading edge stop and the guide roller. To ensure this, the guide roller must be positioned so that the roller just barely rotates and is neither on the sheet trailing edge nor directly on the folded sheet. Such a device is from the German utility model DE 299 04 757 known. Herein, a device for holding down and loading of moving sheet-like objects is proposed, in which one or more guide rollers are provided for holding down the objects. For exact positioning of the guide rollers, at least one of these guide rollers is provided with a marking.

Aus der EP 0 807 597 A2 ist eine Vorrichtung zum Positionieren von in einer Falzmaschine bewegten Bogen bekannt. Die Bogen werden von Transportbändern gegen einen Anschlag gefördert, wobei sich das obere und untere Transportband nur im Einlauf- und Auslaufbereich des Schwertfalzwerkes berühren.From the EP 0 807 597 A2 is a device for positioning in one Folding machine known moving sheet. The sheets are conveyed by conveyor belts against a stop, with the upper and lower conveyor belt touching only in the inlet and outlet area of the blade folder.

Bei heute üblichen Messerfalzwerken wird ein Bogen mit voller Produktionsgeschwindigkeit gegen einen feststehenden Anschlag gefahren. Die kinetische Energie der Bewegung spannt den Bogen wie eine Feder und wird dann als Rücksprung schlagartig frei. Beim Zurückspringen wandert der Bogen entgegen der Papierlaufrichtung, so dass seine Lage nicht mehr exakt bestimmt ist. Die Transportbänder laufen weiter und treiben den zurückgesprungenen Bogen wieder mit voller Geschwindigkeit gegen den Anschlag. Der Bogen prellt so lange, bis die Kraft der Bänder und Transporteinrichtungen in Richtung des Anschlags größer ist als die aus der Federkraft des Bogens resultierende Rückspringkraft. Nach einiger Zeit kommt der Bogen zur Ruhe und die Bänder laufen unter ihm durch. Der Bogen kann nun mit dem Schwert gefalzt werden.In today usual Messerfalzwerken is a bow with full Production speed driven against a fixed stop. The kinetic energy of the movement tightens the bow like a spring and then suddenly releases as a return. When jumping back, the sheet moves against the direction of paper travel, so that its position is no longer exactly determined. The conveyor belts continue to run and drive the returned arc back to the stop at full speed. The sheet bounces until the force of the belts and transport means in the direction of the stop is greater than the springback force resulting from the spring force of the sheet. After some time, the bow comes to rest and the tapes go under him. The bow can now be folded with the sword.

Die Dauer, die der sich nun unruhig hin und her bewegende Bogen benötigt, um plan und ausgerichtet vor dem Anschlag zu liegen, reduziert die mögliche Produktionsleistung.The time required for the now restlessly moving bow to lie flat and aligned in front of the fence reduces the potential production output.

Das "Prellen" des Bogens wird umso stärker, je weiter der Bogen zurückspringen kann, da er beim wieder nach vorne Laufen weitere Energie zugeführt bekommt.The "bouncing" of the bow becomes stronger, the further the bow can jump back, as it receives more energy when running forward again.

Zum Vermeiden des Zurückspringens des Bogens von den Anschlägen ist es bekannt, Bürsten an die Falzbogenhinterkante zur Endlagenfixierung des Falzbogens oder eine Bürstenleiste auf die Falzbogenoberseite zu stellen. Die Bürstenleiste, die die Falzbogenoberseite abbremst, ist allerdings gerade für Falzbogen mit einem geringen Flächengewicht nachteilig, da eine symmetrische Anlage und damit ein gleichmäßiges Abbremsen nur schwer möglich ist. Zudem ist die Einstellung und Positionierung der Bürsten oder Bürstenleiste zeitaufwendig.To avoid jumping back of the sheet from the stops, it is known to place brushes against the trailing edge of the trailing edge of the signature sheet or a brush strip on the folded sheet top. However, the brush strip, which slows down the folded sheet top, is disadvantageous especially for folded sheets with a low basis weight, since a symmetrical system and thus a uniform braking is difficult. In addition, the adjustment and positioning of the brush or brush strip is time-consuming.

Mit den aus dem deutschen Gebrauchsmuster DE 93 04 281 bekannten Führungsrollen lässt sich das "Prellen" des Bogens bereits in vielen Anwendungsfällen recht gut vermeiden. Bei hohen Geschwindigkeiten und großen Grammaturen reicht jedoch die Wirkung dieser Führungsrollen allein nicht mehr aus.With the from the German utility model DE 93 04 281 known guide rollers can be the bouncing of the bow already quite good in many cases. At high speeds and large grammages, however, the effect of these leadership roles alone is no longer enough.

Aufgabe der vorliegenden Erfindung ist es deshalb, eine alternative Vorrichtung zu schaffen, die die Beruhigungszeiten des Bogens beim Auftreffen auf den Anschlag eines Messerfalzwerkes auch bei hohen Geschwindigkeiten und großen Grammaturen reduziert und durch die gleichzeitig eine störungsfreie Falzung im Schwertfalzwerk erfolgen kann.Object of the present invention is therefore to provide an alternative device that reduces the settling times of the sheet when hitting the attack of a knife folding even at high speeds and large grammages and can be done by the same time trouble-free folding in the sword folder.

Diese Aufgabe wird gelöst mit einer Vorrichtung gemäß den kennzeichnenden Merkmalen von Anspruch 1.This object is achieved with a device according to the characterizing features of claim 1.

In einer bevorzugten Ausführungsform wird der Bogen zwischen einem oberen und einem unteren Transportband gegen einen Anschlag bewegt. Hierbei berühren sich das obere und untere Transportband jedoch nur im Einlauf- und Auslaufbereich des Schwertfalzwerkes. Die Hinterkante des Bogens wird gerade eben noch von den sich berührenden Transportbändern erfasst. Hierdurch wird einerseits ein Zurückprellen des Bogens vermieden und zum anderen wird gewährleistet, dass der Bogen im Schwertfalzwerk leicht, d.h. ohne Reibung zwischen Bogen und Transportbändern gefalzt werden kann.In a preferred embodiment, the sheet is moved between an upper and a lower conveyor belt against a stop. Here, however, the upper and lower conveyor belts only touch each other in the inlet and outlet areas of the blade folder. The trailing edge of the sheet is just barely covered by the touching conveyor belts. As a result, on the one hand a rebounding of the sheet is avoided and on the other hand it is ensured that the sheet in the sword folder easily, i. can be folded without friction between sheet and conveyor belts.

In einer weiteren vorteilhaften Ausführungsform ist die mindestens eine Andrückrolle formatabhängig verstellbar.In a further advantageous embodiment, the at least one pressure roller is adjustable depending on the format.

In einer besonders bevorzugten Ausführungsform sind sowohl der Vorderkantenanschlag als auch die mindestens eine Andrückrolle für die Hinterkante des Bogens auf beweglichen Schlitten befestigt. Hierdurch wird eine einfache Einstellung auf unterschiedliche Bogenformate möglich.In a particularly preferred embodiment, both the leading edge stop and the at least one pressure roller for the trailing edge of the sheet are mounted on movable carriages. This makes it easy to adjust to different sheet sizes.

Die Figuren zeigen die wesentlichen Teile von einer Ausführungsform der erfindungsgemäßen Vorrichtung 10. In den Figuren wurden dem Fachmann bekannte Elemente wie Antriebe, Kurven, Gehäuse, Steuerungen usw. nur stark vereinfacht gezeigt, wenn sie im Belieben des Fachmanns liegen.The figures show the essential parts of an embodiment of the device 10 according to the invention Elements such as drives, curves, housings, controls, etc. shown only greatly simplified, if they are at the discretion of the expert.

Die gezeigte Ausführungsform der erfindungsgemäßen Vorrichtung 10 ist Teil einer Kombifalzmaschine und ist dort dem ersten Schwertfalzwerk vorgeordnet. Kombifalzmaschinen und Schwertfalzwerke sind dem Fachmann aus dem Stand der Technik in großer Anzahl bekannt. In einer solchen Kombifalzmaschine werden die Parallelbrüche in einer ersten Falzstation im Taschenfalzprinzip gefalzt, während die nachfolgenden Kreuzbrüche mit einem vertikal arbeitenden Falzschwert ausgeführt werden. Hierzu werden die gefalzten Bogen 1 nach dem Parallelbruchausgang zu einer Kreuzbruchstation schlupffrei transportiert.The illustrated embodiment of the device 10 according to the invention is part of a combination folding machine and is there upstream of the first sword folder. Combined folding machines and knife folders are known to those skilled in the art in large numbers. In such a combination folding machine, the parallel breaks are folded in a pocket-folding principle in a first folding station, while the subsequent cross-breaks are carried out with a vertical folding blade. For this purpose, the folded sheet 1 are transported after the parallel break output to a cross-break station without slip.

Beim Ausrichten der Bogen 1 mit Vorderkanten- und Hinterkantenanschlägen im ersten Schwertfalzwerk wird der Falzbogen längsmittig zum nachfolgenden Schwertfalzwerk ausgerichtet.When aligning the sheet 1 with leading edge and trailing edge stops in the first blade folder of the folded sheet is aligned longitudinally to the subsequent blade folder.

Die Fig. 1 zeigt eine erfindungsgemäße Vorrichtung 10. Diese Vorrichtung besteht aus einer unteren Transporteinheit 3 und einer oberen Transporteinheit 4. Die untere Transporteinheit 3 weist als Transportband 3.1 ein Endlosband auf, welches an seinen beiden Enden um Umlenkrollen 3.2 geführt wird. Das Transportband 3.1 bildet so einen unteren Trum 3.3 und einen oberen Trum 3.4.The Fig. 1 shows a device according to the invention 10. This device consists of a lower transport unit 3 and an upper transport unit 4. The lower transport unit 3 has as a conveyor belt 3.1 an endless belt, which is guided at its two ends to guide rollers 3.2. The conveyor belt 3.1 thus forms a lower run 3.3 and an upper run 3.4.

Die obere Transporteinheit 4 weist als Transportband 4.1 ein Endlosband auf, welches an seinen beiden äußeren Enden um Umlenkrollen 4.2 geführt wird. Das Transportband 4.1 bildet so einen unteren Trum 4.3 und einen oberen Trum 4.4.The upper transport unit 4 has as a conveyor belt 4.1 an endless belt, which is guided at its two outer ends around pulleys 4.2. The conveyor belt 4.1 thus forms a lower run 4.3 and an upper run 4.4.

Der untere Trum 4.3 wird weiterhin rechts und links vom Vorderkantenanschlag 5.1 über Umlenkrollen 4.5.2 und 4.6.2 vom oberen Trum 3.4 des unteren Transportbandes 3.1 abgehoben, so dass sich der obere Trum 3.4 des Transportbandes 3.1 und der untere Trum 4.3 des Transportbandes 4.1 nur im Einlaufbereich A und im Auslaufbereich B berühren. Die Berührung der beiden Trume 3.4 und 4.3 in den Bereichen A und B wird unterstützt durch Andrückrollen 4.7, 4.6.3 bzw. 4.7 und 4.5.3.The lower run 4.3 is still lifted right and left of the leading edge stop 5.1 via pulleys 4.5.2 and 4.6.2 from the upper run 3.4 of the lower conveyor belt 3.1, so that the upper run 3.4 of the conveyor belt 3.1 and the lower run 4.3 of the conveyor belt 4.1 only in the inlet area A and in the outlet area B touch. The contact between the two runs 3.4 and 4.3 in the areas A and B is supported by pressure rollers 4.7, 4.6.3 or 4.7 and 4.5.3.

Wie aus Fig. 2 ersichtlich, sind die Umlenkrollen 4.5.2, die Andrückrolle 4.5.3 und der Vorderkantenanschlag 5.1 mit dem Lichttaster 5.2 an beweglichen Schlitten 4.5 befestigt. Weiterhin sind die Umlenkrollen 4.6.2, die Andrückrollen 4.6.3 und 4.6.4 an beweglichen Schlitten 4.6 befestigt. Durch eine auseinander oder gegeneinander gerichtete Bewegung der beweglichen Schlitten 4.5 und 4.6 kann somit der Vorderkantenanschlag 5.1 und die Hinterkantenpositionierung, geleitet durch die Andrückrolle 4.6.4, auf unterschiedliche Formate des Bogens 1 (wie aus den Fig. 1 und 3 ersichtlich) eingestellt werden.How out Fig. 2 can be seen, the pulleys 4.5.2, the pressure roller 4.5.3 and the Leading edge stop 5.1 with the light scanner 5.2 attached to movable carriage 4.5. Furthermore, the pulleys 4.6.2, the pressure rollers 4.6.3 and 4.6.4 attached to movable carriage 4.6. By an apart or against each other directed movement of the movable carriage 4.5 and 4.6 can thus the leading edge stop 5.1 and the trailing edge positioning, guided by the pressure roller 4.6.4, on different formats of the sheet 1 (as shown in Fig. 1 and 3 can be set).

Die Laufgeschwindigkeiten der Transportbänder 3.1 und 4.1 sind gleich.The running speeds of the conveyor belts 3.1 and 4.1 are the same.

Ein Bogen 1 wird mittels der Transportbänder 3.1 und 4.1 mit Hilfe der Andrückrollen 4.7 und 4.6.3 in Transportrichtung (Pfeil T) bis an den Vorderkantenanschlag 5.1 transportiert. Der Bogen wird stets längsmittig zum nachfolgenden Falzschwert ausgerichtet. Zur Einstellung des korrekten Bogenformates wird die eine Hälfte des Verstellweges mit dem beweglichen Schlitten 4.5 und die zweite Hälfte mit dem beweglichen Schlitten 4.6 eingestellt.A sheet 1 is transported by means of the conveyor belts 3.1 and 4.1 by means of the pressure rollers 4.7 and 4.6.3 in the transport direction (arrow T) to the front edge stop 5.1. The bow is always aligned longitudinally to the subsequent folding sword. To set the correct sheet format, one half of the adjustment path is set with the movable carriage 4.5 and the second half with the movable carriage 4.6.

Hierbei positioniert der Vorderkantenanschlag 5.1 die Bogenvorderkante und die Andrückrolle 4.6.4 des beweglichen Schlittens 4.6 die Hinterkante des Bogens 1. Hierdurch wird das Zurückspringen des Bogens 1 beim Anschlagen an den Vorderkantenanschlag 5.1 verhindert.Here, the leading edge stop 5.1 positioned the sheet leading edge and the pressure roller 4.6.4 of the movable carriage 4.6, the trailing edge of the sheet 1. This prevents the jumping back of the sheet 1 when striking the leading edge stop 5.1.

Durch diese Vorrichtung wird erreicht, dass der Bogen zum einen markierungsfrei transportiert wird, eine einfache Formatverstellung ermöglicht wird und der Bogen beim Falzvorgang nicht durch Reibungskräfte zwischen Bogen und Transportbändern beeinflusst wird.By this device it is achieved that the sheet is transported to a mark free, a simple format adjustment is made possible and the sheet during the folding process is not affected by frictional forces between the sheet and conveyor belts.
