Description

Die Erfindung betrifft eine Vorrichtung zum Positionieren der Hinterkante von vorzugsweise in einer Kombifalzmaschine bewegten blattförmigen Gegenständen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for positioning the trailing edge 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.

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 Bürstenleisten 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 trailing edge of the signature. The brush strip that slows down the folded sheet top, however, 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 brushes or brush strips 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 besteht die Rücklaufsperre aus einer Scheibe mit Verzahnung, die an der Führungsrolle angebracht ist und die mit einer an einer drehbaren Schwinge angebrachten Rätsche zusammenwirkt. Bei dieser Ausgestaltung wird der zurückspringende Bogen aufgrund der entstehenden Gleitreibung zwischen Rolle und Bogen wesentlich schneller beruhigt. Der Bogen wird also durch eine erhöhte Reibung abgebremst.In a preferred embodiment, the backstop consists of a disc with toothing, which is attached to the guide roller and which cooperates with a mounted on a rotatable rocker ratchet. In this embodiment, the recessed arc is calmed much faster due to the resulting sliding friction between roller and bow. The bow is thus slowed down by increased friction.

In einer weiteren vorteilhaften Ausführungsform ist an der Schwinge, an der die Führungsrolle gelagert ist, eine Rückschlagfeder befestigt, deren Eintauchtiefe unterhalb des Transportbandes liegt. Durch diese Rückschlagfeder wird das Zurückprallen des Bogens formschlüssig verhindert.In a further advantageous embodiment, a return spring is attached to the rocker on which the guide roller is mounted, whose immersion depth is below the conveyor belt. By this return spring the rebounding of the sheet is positively prevented.

Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen dargelegt.Further advantageous embodiments are set forth in the subclaims.

In den Fig. 1a und 1b ist der prinzipielle Aufbau einer Vorrichtung gemäß dem Stand der Technik gezeigt.1a and 1b, the basic structure of a device according to the prior art is shown.

Die Rolle 6 treibt zusammen mit dem Transportband 4 den Bogen 2 gegen den Anschlag 5. Der Bogen 2 schlägt an, verformt sich wie eine Feder und gibt dann die gespeicherte Energie als Sprungkraft gegen die Transportrichtung ab. Der zwischen Rolle 6 und Band 4 entstehende Keil soll den Bogen abbremsen.The roller 6 drives together with the conveyor belt 4 the sheet 2 against the stop 5. The sheet 2 strikes, deforms like a spring and then outputs the stored energy as a bounce against the transport direction. The resulting between roller 6 and 4 band wedge is to slow down the bow.

Die heute verwendeten Rollen 6 sind, um den Bogentransport zu verbessern und keine Markierungen zu erzeugen, sehr leichtgängig und haben eine sehr geringe Masse. Diese Vorteile beim Bogentransport sind beim Bogen Abbremsen von Nachteil. Der zurückspringende Bogen 2 wölbt sich auf und hebt die Rolle 6 ab. Da die Rolle 6 kaum Rollwiderstand und Masse hat, kehrt sich nun die Drehrichtung um. Der Bogen 2 wird nur noch mit Rollreibung gebremst. Ein stärkeres Andrücken der Rolle 6, um das Abheben zu vermeiden, verursacht in vielen Fällen Markierungen auf dem Bogen 2. Diese Markierungen sind unerwünscht und sollen vermieden werden.The roles used today 6 are to improve the sheet transport and produce no marks, very smooth and have a very low mass. These advantages in sheet transport are braking at the bow of disadvantage. The recessed sheet 2 buckles up and lifts off the roller 6. Since the roller 6 hardly has rolling resistance and mass, now reverses the direction of rotation. The sheet 2 is braked only with rolling friction. A stronger pressing of the roller 6, to avoid the lifting, in many cases causes marks on the sheet 2. These marks are undesirable and should be avoided.

In den Fig. 2a und 2b ist eine erste erfindungsgemäße Ausführungsform dargestellt.FIGS. 2a and 2b show a first embodiment according to the invention.

Die Rolle 6 wird an einer Schwinge 12 gelagert. Die Schwinge 12 ist drehbar gelagert an einem nicht dargestellten Gestell und durch eine Feder nach unten belastet. Wird nun ein Bogen in Bogenlaufrichtung (Pfeil T) transportiert, hebt sich die Rolle 6 leicht an, treibt den Bogen 2 nach vorne und senkt sich wieder auf das Band 4, wenn die Hinterkante des Falzbogens die Rolle durchlaufen hat. An der Rolle 6 ist eine Einrichtung angebracht, die die Umkehr der Drehrichtung unmöglich macht. Bei der vorliegenden Ausführung sind dies eine Scheibe mit Verzahnung 9 und eine Rätsche 11, die an einem Hebel 15 befestigt ist. Der Hebel 15 ist an seinem anderen Ende an der Schwinge 12 befestigt. Die Form der Verzahnung ermöglicht der Rolle 6 nur die Drehung in Bogenlaufrichtung. Der zurückspringende Bogen 2 hebt zwar immer noch die Rolle 6 ab, diese kann jedoch die Drehrichtung nicht umkehren; der Bogen 2 wird mit Gleitreibung zwischen Rolle und Falzbogen, und nicht mit Rollreibung, gebremst. Die Gleitreibung ist um den Faktor 3 höher.The roller 6 is mounted on a rocker 12. The rocker 12 is rotatably mounted on a frame, not shown, and loaded by a spring down. If a sheet is then transported in the direction of sheet travel (arrow T), the roll 6 rises slightly, drives the sheet 2 forward and sinks back onto the strip 4 when the trailing edge of the folded sheet has passed through the roll. On the roller 6, a device is attached, which makes the reversal of the direction of rotation impossible. In the present embodiment, these are a disc with teeth 9 and a Rätsche 11, which is attached to a lever 15. The lever 15 is fixed at its other end to the rocker 12. The shape of the toothing allows the roller 6 only the rotation in the sheet running direction. Although the recoil sheet 2 still lifts off the roller 6, but this can not reverse the direction of rotation; The sheet 2 is braked with sliding friction between roller and folded sheet, and not with rolling friction. The sliding friction is higher by a factor of 3.

In den Figuren 3a und 3b ist eine weitere erfindungsgemäße Ausführungsform dargestellt.FIGS. 3 a and 3 b show a further embodiment according to the invention.

An der Schwinge 12 ist eine Rückschlagsfeder 13 befestigt. Wird nun ein Bogen in Bogenlaufrichtung transportiert, hebt sich die Feder und lässt den Bogen passieren. Hat die Hinterkante des Bogens die Rückschlagfeder passiert, senkt diese sich ab und der Anschlag senkt sich so weit, dass er tiefer als das Band 4 ist und somit den zurückspringenden Bogen nicht passieren lässt. Die Eintauchtiefe der Feder 13 wird durch den Bolzen 14 nach unten begrenzt. Der Anschlag der Feder ist kurz vor dem Berührungspunkt der Rolle angebracht. Die Rolle ist somit leichter zu positionieren und die Rückschlagfeder erhält die Möglichkeit, nach unten zu schwenken, bevor der Bogen zurückkommt.On the rocker 12, a return spring 13 is attached. Now, when a sheet is transported in sheet travel direction, the spring lifts and lets the bow pass. If the trailing edge of the bow passes the return spring, it lowers and the stop sinks so low that it is deeper than the tape 4 and thus does not let the receding sheet pass. The immersion depth of the spring 13 is limited by the bolt 14 down. The stop of the spring is mounted just before the point of contact of the roller. The roller is thus easier to position and the return spring is given the opportunity to pivot down before the bow comes back.

In beiden Ausführungsformen ist eine sichere Abbremsung und Positionierung auch von schweren Bogen bei hoher Verarbeitungsgeschwindigkeit gewährleistet.In both embodiments, a secure braking and positioning of heavy sheets at high processing speed is guaranteed.
