Description

Die Erfindung betrifft eine Vorrichtung zum Längsfalzen einer oder mehrerer übereinanderliegender Bahnen.The invention relates to a device for longitudinally folding one or more superimposed webs.

Aus dem Fachbuch «Techniken, Systeme, Maschinen», Polygraph-Verlag, von Oscar Frey, 1979, Seite 49 ff., ist es beispielsweise bekannt, Druckträgerbahnen über einen Falztrichter zur Bildung eines Längsfalzes zu ziehen. Dabei wird die Bahn in einem Zug gefaltet, wobei die Falzkraft selbst dem Bahnzug entnommen wird. Durch die Trichtergeometrie wird die Bahn um 90° umgelenkt, was insbesondere bei mehreren Lagen zu Wegdifferenzen führt, so dass ein einwandfreier Bahnlauf nicht immer gewährleistet ist.For example, it is known from the specialist book "Techniques, Systems, Machines", Polygraph Verlag, by Oscar Frey, 1979, page 49 ff., To pull print carrier webs over a former to form a longitudinal fold. The web is folded in one go, the folding force itself being taken from the web train. Due to the funnel geometry, the web is deflected by 90 °, which leads to path differences, particularly in the case of several layers, so that a perfect web run is not always guaranteed.

Aufgabe der Erfindung ist es, die Herstellung des Längsfalzeskontinuierlich in mehreren Schritten vorzunehmen, um die besonders bei mehrbahnigem Betrieb auftretenden Laufprobleme zu eliminieren. Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Anspruchs gelöst. Vorteilhafte Weiterbifdungen ergeben sich aus den Unteransprüchen sowie aus der Beschreibung in Verbindung mit den Zeichnungen. In diesen zeigen jeweils schematisch:

  • Fig. eine Vorderansicht auf die erfindungsgemässe Längsfalzvorrichtung,
  • Fig. 2 eine Seitenansicht der Längsfalzstufen gemäss Fig. 1 und
  • Fig. 3 und 4 eine Abwicklung der X-Y-Ebene und derZ-Y-Ebene.
The object of the invention is to produce the longitudinal fold continuously in several steps in order to eliminate the running problems which occur particularly in multi-lane operation. This object is achieved by applying the features of the characterizing part of the claim. Advantageous further developments result from the subclaims and from the description in conjunction with the drawings. Each of these shows schematically:
  • 1 is a front view of the longitudinal folding device according to the invention,
  • Fig. 2 is a side view of the longitudinal folding steps according to Fig. 1 and
  • Figures 3 and 4 are a development of the XY plane and the Z-Y plane.

Die beispielsweise aus einer nicht dargestellten Druckmaschine bzw. aus dem dieser nachgeordneten Falzaufbau kommende Druckträgerbahn soll in mehreren Stufen S1 bis S5 längsgefalzt werden. Jede der Stufen S1 bis S5 umfasst ein Walzenpaar 1,1', 2, 2', 3, 3', 4, 4', 5, 5'. Zwischen diesen Walzenpaaren wird die erwähnte längs zu falzende Bahn 6, beispielsweise eine oder mehrere übereinanderliegende bedruckte Papierbahnen, in Richtung des Pfeiles 7 durchgeführt. Wie im Zusammenhang mit der Darstellung gemäss Fig. 2 angedeutet, umfasst jedes der Falzwalzenpaare 2, 2', 3, 3', 4, 4', 5, 5' mit einem Winkelprofil versehene Walzen, von denen jeweils die Walzen 2,3,4,5 oberhalb und die Walzen 2', 3', 4', 5' unterhalb der Druckträgerbahn 6 angeordnet sind. Das nicht profilierte Walzenpaar 1, 1' dient lediglich als Klemmstelle bzw. als Zugwalzenpaar. Das gleiche gilt für das hinter der Längsfalzvorrichtung angedeutete, in der Falzebene liegende Walzenpaar 8, 8', zwischen dem die bereits gefalzte Bahn 6 hindurchgeführt wird. Vorzugsweise eignet sich die erfindungsgemässe Längsfalzvorrichtung zum Falzen von mehreren Bahnen, jedoch versteht es sich, dass auch nur eine einzige Bahn 6 längsgefalzt werden kann.The print carrier web coming, for example, from a printing machine (not shown) or from the folding structure arranged downstream of it is to be longitudinally folded in several stages S1 to S5. Each of the stages S1 to S5 comprises a pair of rollers 1, 1 ', 2, 2', 3, 3 ', 4, 4', 5, 5 '. Between these pairs of rollers, the aforementioned web 6 to be folded longitudinally, for example one or more printed paper webs lying one above the other, is carried out in the direction of the arrow 7. As indicated in connection with the illustration according to FIG. 2, each of the folding roller pairs 2, 2 ', 3, 3', 4, 4 ', 5, 5' comprises rollers provided with an angular profile, of which the rollers 2, 3, 4,5 above and the rollers 2 ', 3', 4 ', 5' below the print carrier web 6 are arranged. The non-profiled pair of rollers 1, 1 'serves only as a nip or as a pair of pull rollers. The same applies to the pair of rollers 8, 8 'indicated behind the longitudinal folding device and lying in the folding plane, between which the already folded web 6 is passed. The longitudinal folding device according to the invention is preferably suitable for folding a plurality of webs, but it goes without saying that only a single web 6 can be longitudinally folded.

Wie aus Fig. 2 ersichtlich ist, sind in erfindungsgemässer Weise die einzelnen Falzstufen S2, S3, S4 und S5 höhenversetzt, d.h. sie liegen höhenmässig in unterschiedlichen Ebenen. Dadurch ergibt sich der in der Darstellung nach links abfallende Falzweg für die Bahn 6. Des weiteren lässt Fig. 2 erkennen, dass die durch die Mittelpunkte eines jeden Falzwalzenpaares verlaufenden Koordinaten ZB bis ZE nach links geneigt sind, während die Koordinate ZA senkrecht zu der einlaufenden Bahn 6 steht.As can be seen from FIG. 2, the individual folding stages S2, S3, S4 and S5 are offset in height in the manner according to the invention, that is to say they lie at different levels in terms of height. This results in the fold path for the web 6, which drops to the left in the illustration. Furthermore, FIG. 2 shows that the coordinates Z B to Z E running through the centers of each pair of fold rollers are inclined to the left, while the coordinate Z A is vertical to the incoming web 6.

Die Profilierungen der Falzwalzenpaare 2, 2' bis 5,5' zeigen, dass der Falzvorgang schrittweise von rechts nach links durchgeführt wird. Das der Erfindung zugrunde liegende Längsfalzprinzip besteht nun darin, dass bei einem vorgegebenen Abstand von einer Falzstufe zur anderen, beispielsweise von S1 zu S2, der Höhenversatz der nachfolgenden Falzstufe, d.h. des Falzwalzenpaares 2,2', bezogen auf das vorangehende Walzenpaar, hier 1, 1 um einen bestimmten Wert verändert, hier nach unten versetzt wird, und dass die durch das Falzwalzenpaar 2, 2' verlaufende senkrechte Ebene bzw.die RaumkoordinateZB um einen bestimmten Betrag geneigt, hier nach links, werden muss. Der Höhenversatz des Falzwalzenpaares 2, 2' und die Neigung der Mittelsenkrechten bzw. der Koordinate ZB müssen so gross sein, dass zwischen den Stufen, hier S1, S2, das Mass der Mittelfaser, hier M', dem Mass der zugeordneten Randfaser, hier R', entspricht. Dadurch und durch die Möglichkeit, innere Bahnspannungen während der Teilfalzvorgänge abzubauen, eignet sich das erfindungsgemässe Prinzip besonders zum Falzen mehrerer übereinanderliegender Bahnen. In der erfindungsgemässen Längsfalzvorrichtung wird die Falzkraft nicht mehr dem Bahnzug entnommen, sondern durch die Falzwalzen 2, 2' bis 5, 5' jeweils durch Druckkraft erzeugt. Die Führung der beiden Seiten der zu falzenden Bahn kann, falls dies erforderlich ist, durch Leitelemente, z. B. durch Leitbleche oder durch Walzen, vorgenommen werden. Ein derartiges Falzwerk ist in Verbindung mit einer einstellbaren Schneidvorrichtung Format-variabel, was einen weiteren Vorteil bedeutet. Besonders bei extrem breiten Druckmaschinen werden nunmehr Laufprobleme bei mehrlagigen Bahnen eliminiert. Der Sammelvorgang kann bereits vorwiegend im Wendeaufbau, der bekanntlich den Druckmaschinen jeweils nachgeordnet ist, vorgenommen werden. Zur Verdeutlichung des der Erfindung zugrunde liegenden Falzprinzips, das auch als Profilfalzprinzip bezeichnet werden kann, wurden in jedes der Falzwalzenpaare 1, l' bis 5, 5' der Falzstufen S1 bis S5 ein Koordinaten- bzw. Achsenkreuz gelegt, in dem die drei Raumachsen X, Y, Z entsprechend den einzelnen Falzstufen S1 bis S5 jeweils mit einem Index, nämlich A bis E, gekennzeichnet wurden. In dem Achsenkreuz der Falzstufe S1 ergibt sich somit die Bezeichnung XA, YA, ZA, wobei der Mittelpunkt der Achsenkreuze ausschliesslich mit einem Buchstaben, hier A, bezeichnet ist.The profiles of the folding roller pairs 2, 2 'to 5.5' show that the folding process is carried out step by step from right to left. The longitudinal folding principle on which the invention is based now consists in the fact that, given a predetermined distance from one folding stage to another, for example from S1 to S2, the height offset of the subsequent folding stage, ie of the pair of folding rollers 2, 2 ', based on the preceding pair of rollers, here 1, 1 changed by a certain value, here shifted downwards, and that the vertical plane running through the folding roller pair 2, 2 'or the spatial coordinate Z B must be inclined by a certain amount, here to the left. The height offset of the pair of folding rollers 2, 2 'and the inclination of the perpendicular bisector or the coordinate Z B must be so great that between the steps, here S1, S2, the dimension of the middle fiber, here M', the dimension of the associated edge fiber, here R '. Because of this and because of the possibility of reducing internal web tensions during the partial folding processes, the principle according to the invention is particularly suitable for folding a plurality of webs lying one above the other. In the longitudinal folding device according to the invention, the folding force is no longer removed from the web tension, but is generated by the folding rollers 2, 2 'to 5, 5' in each case by compressive force. The leadership of the two sides of the web to be folded can, if necessary, by guide elements, for. B. by baffles or by rolling. Such a folder is format-variable in conjunction with an adjustable cutting device, which means a further advantage. With extremely wide printing presses in particular, running problems with multilayer webs are now eliminated. The collecting process can already be carried out predominantly in the reversing structure, which is known to be arranged downstream of the printing press. To illustrate the folding principle underlying the invention, which can also be referred to as a profile folding principle, a coordinate or axis cross was placed in each of the folding roller pairs 1, 1 'to 5, 5' of the folding stages S1 to S5, in which the three spatial axes X , Y, Z were each identified by an index, namely A to E, corresponding to the individual folding levels S1 to S5. The designation X A , Y A , Z A thus results in the axis cross of the folding step S1, the center of the axis crosses being designated exclusively with a letter, here A.

Fig. 3 zeigt dann die Abwicklung der Bahn 6 zwischen den einzelnen Stufen S1 bis S5 in X-Y-Ebene und Fig. 4 in Z-Y-Ebene. Die Randfaser zwischen den einzelnen Stufen S1 bis S5 ist mit R, R', R", R"', R"", R""' bezeichnet. Das gleiche gilt für die Abwicklung gemäss Fig. 4, bei der ausserdem noch die Falzwinkel für die einzelnen Stufen S1 bis S5 angegeben sind.3 then shows the development of the web 6 between the individual stages S1 to S5 in the X-Y plane and FIG. 4 in the Z-Y plane. The edge fiber between the individual stages S1 to S5 is denoted by R, R ', R ", R"', R "", R "" '. The same applies to the processing according to FIG. 4, in which the folding angles for the individual stages S1 to S5 are also specified.

Aus den Abwicklungen gemäss Fig. 3 und 4 ergibt sich, dass bei einem vorbestimmten Abstand zwischen zwei Falzstufen, beispielsweise S1 und S2, zwecks Wegausgleich zwischen Bahnmitte und Bahnrand R Neigung und Höhenversatz des nachfolgenden Falzwalzenpaares, hier 2, 2', ein bestimmtes Mass betragen müssen.It follows from the developments according to FIGS. 3 and 4 that at a predetermined distance between two folding stages, for example S1 and S2, the inclination and height offset of the subsequent pair of folding rollers, here 2, 2 ', for the purpose of compensating the path between the web center and the web edge R, are a certain dimension have to.

Es ist somit erforderlich, von Stufe zu Stufe Neigung und Höhenversatz individuell zu berechnen. Vorzugsweise werden hierzu jeweils die Koordinaten im Achsenkreuz einer jeden der Stufen S1 bis S5 schrittweise berechnet. Diese Berechnung erfolgt unter Anwendung der allgemein bekannten trigonometrischen Funktionen und der Ermittlung der X-Komponenten durch die Seitenlänge im Raum.It is therefore necessary to calculate the inclination and height offset individually from level to level. For this purpose, the coordinates in the axis cross of each of the stages S1 to S5 are preferably calculated step by step. This calculation is carried out using the generally known trigonometric functions and the determination of the X components by the side length in space.

Im nachfolgenden wird unter Bezugnahme auf Fig. 3 und 4 dieser Vorgang anhand eines Ausführungsbeispiels näher verdeutlicht.This process is illustrated in more detail below with reference to FIGS. 3 and 4 using an exemplary embodiment.
