Abstract

In a longitudinal folding device for a web of printing material on a folding apparatus of a web-fed rotary printing machine, which has a former mounted rotatably in relation to the machine side walls at a pivot point, the pivot point has previously been arranged on the rear side of the former. During a swivel movement of the former, the former roller arranged above the former and the former inlet rollers arranged on both sides of the former nose had to be guided. <??>By placing the pivot point on the side of the web of printing material facing away from the former - preferably near to the intersection of two straight lines, the first of which extends perpendicular to the former inclination through its upper end and the second of which extends perpendicular through the lower end of the former - the vertical offset of the former nose and the displacement of the upper end is minimised to such an extent that the need for guiding is obviated. <IMAGE>

Description

Die Erfindung betrifft eine Längsfalzvorrichtung für eine Bedruckstoffbahn an einem Falzapparat einer Rollenrotations-­Druckmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a longitudinal folding device for a printing material web on a folder of a web-fed rotary printing press according to the preamble of patent claim 1.

Aus A. Braun, Atlas des Zeitungs- und Illustrationsdruckes, Frankfurt/Main 1960, Seite 66 ist eine gattungsgemäße Längsfalzvorrichtung bekannt, deren Falztrichter in einem gewissen Winkelbereich verschwenkbar ist. Für eine einwandfreie Funktion eines Falztrichters ist es erforderlich, daß dessen oberes Ende bei geringem Abstand möglichst tangential auf die Peripherie einer oberhalb des Falztrichters angeordnete angetriebene Trichterwalze gerichtet ist (siehe Abb. 81 II) und daß dessen als Trichternase bezeichnetes unteres Ende sich stets knapp oberhalb der Achshöhe eines Paares parallel angeordneter Trichtereinlaufwalzen befindet (siehe Abb. 81 III). Wenn nun bestimmte Produktionsarten eine Verlagerung der Trichternase in horizontaler Richtung erfordern und diese durch eine Verschwenkung des Falztrichters erreicht wird, so ergibt sich bei bekannten Anordnungen der Nachteil einer beträchtlichen vertikalen Verlagerung der Trichternase und einer horizontalen Verlagerung des oberen Endes des Falztrichters. Diese Abweichungen mußten bislang mit einer aufwendigen Nachführung der Trichterwalzen und/oder der Trichtereinlaufwalze korrigiert werden.From A. Braun, Atlas of Newspaper and Illustration Printing, Frankfurt / Main 1960, page 66, a generic longitudinal folding device is known, the former of which can be pivoted within a certain angular range. For the correct functioning of a former, it is necessary that the upper end of it, at a short distance, is directed as tangentially as possible to the periphery of a driven former roller arranged above the former (see Fig. 81 II) and that its lower end, known as the former nose, is always just above the axle height of a pair of funnel inlet rollers arranged in parallel (see Fig. 81 III). If certain types of production now require a displacement of the former in the horizontal direction and this is achieved by pivoting the former, then known arrangements have the disadvantage of a considerable vertical displacement of the former and a horizontal displacement of the upper end of the former. Up to now, these deviations had to be corrected with a complex tracking of the funnel rollers and / or the funnel inlet roller.

Der Erfindung liegt die Aufgabe zugrunde, eine Längsfalzvorrichtung zu schaffen, die diese Nachteile vermeidet.The invention has for its object to provide a longitudinal folding device which avoids these disadvantages.

Diese Aufgabe wird durch den kennzeichnenden Teil des Patentanspruchs 1 gelöst. Eine Verlagerung des Schwenkpunktes des Falztrichters, der bei allen bekannten Ausführungen auf dessen Rückseite angeordnet ist, auf die Vorderseite, d.h. auf die dem Falztrichter abgewandte Seite der Bedruckstoffbahn, bewirkt eine deutliche Verminderung der eingangs erwähnten unerwünschten Verlagerungen der Trichternase und des oberen Trichterendes, so daß sich eine Nachführung der Walzen erübrigt.This object is achieved by the characterizing part of patent claim 1. A displacement of the pivot point of the former, which is arranged on the back of all known designs, on the front, ie on the side of the printing material web facing away from the former, results in a significant reduction in the undesirable mentioned at the beginning Displacements of the funnel nose and the upper end of the funnel, so that there is no need to adjust the rollers.

Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the invention can be found in the subclaims.

Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnungen beschrieben.

  • Fig. 1 zeigt eine Seitenansicht auf Falztrichter und Schwenkhebel,
  • Fig. 2 eine Vorderansicht dazu und
  • Fig. 3 eine vorteilhafte Ausgestaltung eines Details aus Fig. 1.
An exemplary embodiment of the invention is described below with reference to the drawings.
  • 1 shows a side view of the former and the pivot lever,
  • Fig. 2 is a front view of this and
  • 3 shows an advantageous embodiment of a detail from FIG. 1.

In Fig. 1 ist eine Bedruckstoffbahn 1 gezeigt, die in einer Längsfalzvorrichtung eines Falzapparates einer nicht näher dargestellten Rollenrotations- Druckmaschine über eine Leitwalze 2 und eine angetriebene Trichterwalze 3 einem Falztrichter 4 zugeführt wird. Nachdem die Bedruckstoffbahn 1 über das spitz zulaufende untere Ende des Falztrichters 4, das als Trichternase 5 bezeichnet wird, in Längsrichtung gefalzt ist, wird sie zwischen den beiderseits der Trichternase 5 parallel zueinander angeordneten Trichtereinlaufwalzen 6 hindurchgeführt, wobei der entstandene Falz zusammengedrückt und somit in seiner Form stabilisiert wird.1 shows a printing material web 1, which is fed to a folding former 4 in a longitudinal folding device of a folding apparatus of a web-fed rotary printing press, not shown, via a guide roller 2 and a driven former roller 3. After the printing material web 1 is folded in the longitudinal direction over the tapering lower end of the former 4, which is referred to as the former nose 5, it is guided between the former inlet rollers 6 arranged parallel to one another on both sides of the former nose 5, the resulting fold being compressed and thus in it Shape is stabilized.

Gemäß der Erfindung ist der Falztrichter 4 gegenüber den in Fig. 2 angedeuteten Maschinenseitenwänden 7 derart drehbar gelagert, daß der Schwenkpunkt S auf der dem Falztrichter 4 abgewandten Seite der Bedruckstoffbahn 1 angeordnet ist.According to the invention, the former 4 is rotatably supported relative to the machine side walls 7 indicated in FIG. 2 in such a way that the pivot point S is arranged on the side of the printing material web 1 facing away from the former 4.

In einer vorteilhaften Weiterbildung liegt der Schwenkpunkt S nahe am Schnittpunkt zweier Gerader 8 und 9. Die erste Gerade 8 verläuft durch das obere Ende der Falztrichterkante 10 und steht senkrecht auf deren Schräge, die durch den Neigungswinkel ß definiert ist. Die zweite Gerade 9 verläuft senkrecht (bezüglich einer zum Maschinenfundament parallelen Horizontalen) durch das untere Ende des Falztrichters 4, d.h. durch die Trichternase 5.In an advantageous development, the pivot point S is close to the intersection of two straight lines 8 and 9. The first straight line 8 runs through the upper end of the former edge 10 and is perpendicular on their slope, which is defined by the angle of inclination ß. The second straight line 9 runs vertically (with respect to a horizontal parallel to the machine foundation) through the lower end of the former 4, ie through the former nose 5.

Im günstigsten Fall liegt der Schwenkpunkt S genau im Schnittpunkt der Geraden 8 und 9. Wie die an den Fußpunkten der Geraden 8 und 9 angedeuteten Kreisbögen zeigen, bewirkt diese Anordnung bei einer Verdrehung des Falztrichters 4 um den Schwenkpunkt S folgende Vorteile:In the best case, the pivot point S lies exactly at the intersection of the straight lines 8 and 9. As the circular arcs indicated at the base points of the straight lines 8 and 9 show, this arrangement brings about the following advantages when the former 4 is rotated about the pivot point S:

An der Trichternase 5 ist ein relativ großer horizontaler Verstellweg auf einer annähernd zu den Achsen der Trichtereinlaufwalzen 6 parallelen Bahn möglich. Die Trichternase 5 verändert ihre Höhe dabei kaum; sie entfernt sich nur um einen vernachlässigbar kleinen Weg aus der Mitte der Trichtereinlaufwalzen 6. Eine vertikale Nachführung der Trichtereinlaufwalzen 6 wird somit überflüssig.A relatively large horizontal adjustment path is possible on the funnel nose 5 on a path approximately parallel to the axes of the funnel inlet rollers 6. The funnel nose 5 hardly changes its height; it only moves a negligibly small distance from the center of the hopper inlet rollers 6. Vertical tracking of the hopper inlet rollers 6 is therefore unnecessary.

Das obere Ende des Falztrichters 4 bewegt sich auf einer annähernd zur Falztrichterkante 10 parallelen Bahn; die Falztrichterkante 10 ist dabei weiterhin weitestgehend tangential auf die Peripherie der Trichterwalze 3 gerichtet. Eine Nachführung der Trichterwalze 3 entfällt somit.The upper end of the former 4 moves on a path approximately parallel to the former edge 10; the former 10 is still largely tangential to the periphery of the former roll 3. A tracking of the hopper roller 3 is therefore not necessary.

Baulich realisiert ist diese Lage des Schwenkpunktes S im Ausführungsbeispiel durch zwei Schwenkhebel 11, die nahe der Innenseiten der Maschinenseitenwände 7 parallel zu diesen bewegbar angeordnet sind. Die Schwenkhebel 11 weisen an einem Ende an ihrer der Maschinenseitenwand 7 zugewandten Außenseite jeweils einen Bolzen 12 auf, der von einer in der jeweiligen Maschinenseitenwand 7 vorgesehenen Lagerbohrung 13 aufgenommen wird. Am anderen Ende, das in seitlicher Projektion (Fig. 1) hinter dem Falztrichter liegt, sind beide Schwenkhebel 11 durch eine an ihrer Innenseite befestigte Stange 14 verbunden. An der Rückseite des Falztrichters 4 ist wenigstens eine Halterung 15 vorgesehen, die die Stange 14 umgreift und mittels derer sich der Falztricher 4 auf der Stange 14 abstützt.This position of the pivot point S is structurally realized in the exemplary embodiment by means of two pivot levers 11 which are arranged to be movable parallel to the inner sides of the machine side walls 7. At one end, the pivot levers 11 each have a bolt 12 on their outer side facing the machine side wall 7, which is received by a bearing bore 13 provided in the respective machine side wall 7. At the other end, which lies behind the folding former in a lateral projection (FIG. 1), both pivot levers 11 are connected by a rod 14 fastened to their inside. At the rear of the former 4, at least one holder 15 is provided, which engages around the rod 14 and by means of which the former 4 is supported on the rod 14.

In einer vorteilhaften Weiterbildung ist der Falztrichter 4 mittig in zwei Hälften 4 a und 4 b geteilt (Fig. 2). Jede der Hälften 4 a, 4 b weist an ihrer Rückseite eine Halterung 15 a, 15 b auf, die jeweils die Stange 14 umgreift. Die Halterungen 15 a, 15 b weisen zwei gegenläufig schrägstehende langlochartige Durchbrüche 16 auf. In der Stange 14 ist auf Höhe der Durchbrüche 16 je ein Bolzen 17 verankert, der in den jeweiligen Durchbruch 16 hineinragt.In an advantageous development, the former 4 is divided in the middle into two halves 4 a and 4 b (FIG. 2). Each of the halves 4 a, 4 b has on its back a holder 15 a, 15 b, which engages around the rod 14. The brackets 15 a, 15 b have two obliquely obliquely slotted perforations 16. A bolt 17, which projects into the respective opening 16, is anchored in the rod 14 at the level of the openings 16.

Alternativ dazu können die Halterungen 15 a, b auch Innengewinde mit entgegengesetzter Gewindesteigung und die Stange 14 zwei entsprechende mit einem Außengewinde entgegengesetzter Steigung versehene Abschnitte aufweisen.As an alternative to this, the brackets 15 a, b can also have internal threads with an opposite thread pitch and the rod 14 can have two corresponding sections provided with an external thread of opposite pitch.

Durch eine Drehung der Stange 14 werden - wie in Fig. 3 angedeutet - die Halterungen 15 a und 15 b auseinandergespreizt oder bei gegenläufiger Drehung der Stange 14 enger zusammengeführt. Mit dieser Einrichtung läßt sich in vorteilhafter Weise die Neigung der beiden Trichterhälften 4 a, 4 b verstellen. Eine solche Winkelverstellung des Trichterflankenwinkels α ist bei einer geringfügigen Verschwenkung des Falztrichters 4 nicht erforderlich; jede größere Verstellung, bei der sich der Winkel ß, den die Falztrichterkante 10 mit der Horizontalen einschließt, wesentlich ändert, erfordert jedoch eine Anpassung des Trichterflankenwinkels α. Dieser wird - wie Fig. 2 zeigt - in frontaler Projektion an der Spitze eine Trichterhälfte 4 a, 4 b gemessen zwischen Trichtermitte und Außenkante einer Hälfte.By rotating the rod 14 - as indicated in Fig. 3 - the brackets 15 a and 15 b spread apart or brought closer together in the opposite rotation of the rod 14. With this device, the inclination of the two funnel halves 4 a, 4 b can be adjusted in an advantageous manner. Such an angular adjustment of the former flank angle α is not necessary with a slight pivoting of the former 4; however, any major adjustment at which the angle β, which the former edge 10 includes with the horizontal, changes significantly, requires an adjustment of the former flank angle α. As shown in FIG. 2, this is measured in a frontal projection at the top of a funnel half 4 a, 4 b between the funnel center and the outer edge of a half.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung dienen die Schwenkhebel 11 gleichzeitig als Träger weiterer Zusatzaggregate. Hierzu ist zwischen den Schwenkhebeln 11 auf der Vorderseite des Trichters eine weitere Stange 18 senkrecht zur Falztrichterkante 10 verschiebbar angebracht. Auf dieser Stange 18 ist ein Schneid-, Sick- oder Perforierrad 19 angeordnet, das im Bedarfsfall an den Falztrichter 4 anstellbar ist und die Bedruckstoffbahn 1 in Höhe der Falztrichterkante 10 schneidet, sickt oder perforiert.In a further advantageous embodiment of the invention, the pivot levers 11 serve at the same time as carriers for further additional units. For this purpose, a further rod 18 is slidably mounted perpendicular to the former edge 10 between the pivot levers 11 on the front of the former. A cutting, beading or perforating wheel 19 is arranged on this rod 18, which can be adjusted to the former 4 if necessary and cuts, corrugates or perforates the printing material web 1 at the level of the former 10.

Die Verschwenkung des Falztrichters 4 erfolgt durch eine mit einem Zwischengelenk versehene Spindelstange 20, die mit einem Ende an einer Halterung 21 an der Rückseite des Falztrichters 4 angelenkt ist und die an ihrem anderen Ende ein Gewinde aufweist, auf dem eine in einem Lagerbock 22 axial gehaltene Mutter 23 sitzt. Eine Verdrehung der Mutter 23 bewirkt eine Verschwenkung des Falztrichters.The pivoting of the former 4 is effected by a spindle rod 20 provided with an intermediate joint, which is articulated at one end to a holder 21 on the rear side of the former 4 and which has a thread at its other end, on which one is held axially in a bearing block 22 Mother 23 is sitting. A rotation of the nut 23 causes the former to pivot.

Mit einer an ihrer Außenseite eine Verzahnung aufweisenden Mutter, an der ein Ritzel eines Stellmotors angreift, ist eine Verschwenkung des Falztrichters auch in einfacher Weise von einem zentralen Stellpult steuerbar.With a nut having teeth on its outside, on which a pinion of an actuator engages, a pivoting of the former can also be controlled in a simple manner from a central control panel.
