Description

Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Führen einer Kante einer Signatur in einer Druckmaschine, insbesondere eine Vorrichtung und ein Verfahren zur Vermeidung von Knicken in der offenen Kante einer in einer Druckmaschine gefalzten Signatur bei der Übergabe der Signatur an einen anderen Abschnitt der Druckmaschine.The present invention relates to an apparatus and a method for guiding a Edge of a signature in a printing press, in particular a device and a Process for avoiding kinks in the open edge of a press folded signature when passing the signature to another section of the Printing press.

In Druckmaschinen, z. B. Offsetdruckmaschinen, in denen Materialbahnen bedruckt werden, wird die bedruckte Bahn in Signaturen geschnitten, die anschließend gefalzt werden. Eine Signatur ist ein in einer Druckmaschine von einer Bahn geschnittener Abschnitt, der einmal oder mehrmals gefalzt wird. In Fig. 6 ist eine gefalzte Signatur S gezeigt, die eine Falzkante F und eine offene Kante O aufweist. Die gefalzten Signaturen S werden zusammengetragen und zu einem fertigen Druckprodukt, z. B. einer Zeitschrift, gebunden.In printing machines, e.g. B. offset printing machines in which material webs are printed, the printed web is cut into signatures, which are then folded. A Signature is a section cut from a web in a printing press that once or is folded several times. In Fig. 6 a folded signature S is shown, which is a folded edge F and has an open edge O. The folded signatures S are gathered and to a finished printed product, e.g. B. a magazine bound.

In modernen Druckmaschinen werden der Schneidevorgang und der Falzvorgang mit hoher Geschwindigkeit durchgeführt. Alternativ ist es ebenso möglich, die Bahn zuerst zu falzen und anschließend zu schneiden. Es gibt verschiedene bekannte Vorrichtungen, in denen eine bedruckte Bahn bei hoher Geschwindigkeit exakt in relativ gleichmäßige Abschnitte geschnitten und anschließend gefalzt wird, bzw. umgekehrt.In modern printing machines, the cutting process and the folding process are carried out at high speeds Speed performed. Alternatively, it is also possible to fold the web first and then cut. There are various known devices in which one printed web at high speed exactly in relatively even sections is cut and then folded, or vice versa.

Die gefalzten Signaturen werden in der Regel mittels Bandvorrichtungen aus den Falz- und Schneidevorrichtungen heraus transportiert. Fig. 4 ist eine Querschnitts- bzw. Seitenansicht und Fig. 5 eine perspektivische Teilansicht einer Druckmaschine des Standes der Technik, in der eine gefalzte Signatur S mittels einer Bandvorrichtung T in eine Richtung D aus einer Schneide- und Falzvorrichtung M herausbefördert wird. Die Bandvorrichtung T umfasst ein Band oder mehrere Bänder B, die sich kontinuierlich in eine Richtung d bewegen, mindestens eine Seite der gefalzten Signaturen S erfassen und diese geradlinig transportieren. Eines der Bänder B der Bandvorrichtung T überlappt in der Regel die offene Kante O der gefalzten Signaturen S und ist breit genug, um zu gewährleisten, dass auch bei Schwankungen in der Breite W der gefalzten Signaturen S die offene Kante O der gefalzten Signatur S immer von dem Band B überlappt wird. Durch diese Anordnung wird sichergestellt, dass die offene Kante O von dem Band B niedergehalten wird, so dass die Ecken C der offenen Kanten O nicht umgeknickt werden können.The folded signatures are usually made from the folding and Cutters transported out. 4 is a cross-sectional side view and FIG. 5 is a partial perspective view of a printing machine of the prior art, in the one folded signature S by means of a tape device T in a direction D from a Cutting and folding device M is conveyed out. The belt device T comprises a Band or several bands B that move continuously in a direction d, Capture at least one side of the folded signatures S and rectilinearly transport. One of the bands B of the band device T usually overlaps the open one Edge O of the folded signatures S and is wide enough to ensure that even at Fluctuations in the width W of the folded signatures S the open edge O of the folded ones Signature S is always overlapped by tape B. This arrangement will ensures that the open edge O is held down by the tape B so that the Corners C of the open edges O cannot be folded.

Die in Fig. 4 gezeigte Bandvorrichtung T einer Vorrichtung des Standes der Technik übergibt die gefalzten Signaturen S an die Übergabevorrichtung 101, die sich beispielsweise in eine Richtung R1 dreht und eine Vorrichtung umfasst, mittels derer die Signatur S auf ihrer Außenoberfläche gehalten wird. Die in Fig. 4 gezeigte Signatur S wird von der Bandvorrichtung T an die Außenoberfläche der Übergabevorrichtung 101 übergeben und wird nach dem ungesteuerten Passieren eines Spalts G an ihrer Vorderkante I von einem aus der (durch die gestrichelte Linie) angedeuteten Peripherie einer sich in Richtung R2 drehenden Bremstrommel 6 heraustretenden Greifermechanismus 4, 5 ergriffen.The belt device T shown in FIG. 4 of a device of the prior art transfers the folded signatures S to the transfer device 101, which for example rotates in a direction R1 and comprises a device by means of which the signature S is opened its outer surface is held. The signature S shown in Fig. 4 is from the Transfer belt device T to the outer surface of transfer device 101 and becomes uncontrolled after passing a gap G at its leading edge I from one the periphery (indicated by the dashed line) in the direction of R2 rotating brake drum 6 gripping mechanism 4, 5 gripped.

Ein Nachteil der in Fig. 4 und 5 gezeigten bekannten Vorrichtungen zur Übergabe von gefalzten Signaturen besteht darin, dass die Ecken C der offenen Kante O der gefalzten Signaturen S während der Übergabe von der Bandvorrichtung T an die Bremstrommel 6, von der Bandvorrichtung T an die Übergabevorrichtung 101 oder von der Übergabevorrichtung 101 an eine andere Übergabevorrichtung, z. B. eine nachgeordnete Bremstrommel, häufig unerwünscht umknicken, wie anhand der in Fig. 6 gestrichelt gezeichneten Ecke C' gezeigt ist. Ein Versuch, dieses Problem zu beseitigen, besteht in der elektrostatischen Aufladung der gefalzten Signaturen S. In einer Vorrichtung des Standes der Technik passiert die Bahn einen Falzapparat und wird einmal oder mehrmals gefalzt. Anschließend wird die gefalzte Bahn durch Beaufschlagung mit einer elektrischen Spannung elektrostatisch aufgeladen und in gefalzte Signaturen S geschnitten. Aufgrund der elektrostatischen Aufladung der gefalzten Signaturen S ziehen sich die Seiten der Signatur S und damit auch die offenen Kanten O gegenseitig an und haften aneinander, wodurch die offene Kante O dicker und dadurch die Gefahr des Umknickens der offenen Kante O reduziert wird.A disadvantage of the known devices for the transfer of FIG. 4 and 5 folded signatures is that the corners C of the open edge O of the folded Signatures S during the transfer from the belt device T to the brake drum 6, from the belt device T to the transfer device 101 or from the Transfer device 101 to another transfer device, e.g. B. a subordinate Brake drum, often an unwanted bend, as shown by the dashed line in Fig. 6 drawn corner C 'is shown. One attempt to solve this problem is to electrostatic charging of the folded signatures S. In a device of the stand In technology, the web passes through a folder and is folded once or several times. The folded web is then subjected to an electrical voltage electrostatically charged and cut into folded S signatures. Due to the the sides of the signature S are electrostatically charged on the folded signatures S. and thus also the open edges O and adhere to each other, whereby the open edge O thicker and therefore the risk of the open edge O bending is reduced.

Ein Nachteil der elektrostatischen Aufladung zur Vermeidung von Umknicken besteht darin, dass die nachfolgende Bearbeitung der Signaturen S erschwert wird. Wenn z. B. eine Reihe gefalzter Signaturen S anschließend zu einer Zeitschrift zusammengetragen und geheftet werden soll, müssen die offenen Kanten O jeder gefalzten Signatur S geöffnet werden, damit eine weitere gefalzte Signatur eingefügt werden kann. Die durch die elektrostatische Aufladung hervorgerufene Anziehung an der offenen Kante O beeinträchtigt jedoch das Öffnen und Einfügen von Signaturen S. Darüber hinaus ist die elektrostatische Aufladung trotz der erhöhten Steifigkeit der offenen Kante O aufgrund der elektrostatischen Anziehung nicht zuverlässig genug, um ein Umknicken der Ecken C vollständig zu verhindern.A disadvantage of electrostatic charging to avoid twisting is that the subsequent processing of the signatures S is made more difficult. If e.g. B. a number folded signatures S are then compiled into a magazine and stapled the open edges O of each folded signature S must be opened, so that another folded signature can be inserted. The through the electrostatic However, charge-induced attraction at the open edge O affects this Opening and inserting signatures S. In addition, the electrostatic charge despite the increased stiffness of the open edge O due to the electrostatic Attraction is not reliable enough to completely fold the corners C. prevent.

Demgemäß ist es eine Aufgabe der vorliegenden Erfindung, eine Vorrichtung und ein Verfahren zu schaffen, das ohne elektrostatische Aufladung ein sicheres Führen der Kante einer Signatur ermöglicht, so dass die Gefahr eines Umknickens verringert wird.Accordingly, it is an object of the present invention, an apparatus and an Process to create a safe guiding of the edge without electrostatic charge enables a signature, so that the risk of twisting is reduced.

Diese Aufgabe wird durch die Merkmale der Ansprüche 1 und 12 gelöst.This object is solved by the features of claims 1 and 12.

Weitere Merkmale der Erfindung sind in den Unteransprüchen enthalten.Further features of the invention are contained in the subclaims.

Der Führungsmechanismus ist in der Weise ausgebildet, dass er die Bewegung der offenen Kante der gefalzten Signaturen von dem Übergabemechanismus weg über Zwischenräume zwischen Übergabemechanismen steuert und auf diese Weise ein Umknicken der offenen Kanten der gefalzten Signaturen bei der Übergabe verhindert.The guide mechanism preferably includes a plurality of all of them Narrow slits arranged across the width. The gripper devices include in the Area of the guide mechanism a variety of preferably also over their narrow fingers arranged across the entire width. Those narrow fingers of the Gripper mechanisms are designed in such a way that they pass through the narrow slots of the guide mechanism can run. The guide mechanism is in the way trained that he can see the movement of the open edge of the folded signatures from the Handover mechanism controls over spaces between handover mechanisms and in this way a folding of the open edges of the folded signatures in the Handover prevented.
