Wendestangenanordnung und Verfahren zum Umlenken einer WarenbahnTurning bar arrangement and method for deflecting a web
Die Erfindung betrifft eine Wendestangenanordnung und Verfahren zum Umlenken einer Warenbahn gemäß dem Oberbegriff des Anspruches 1 , 2, 10 oder 11.The invention relates to a turning bar arrangement and method for deflecting a web according to the preamble of claim 1, 2, 10 or 11.
In Rotationsdruckmaschinen werden im allgemeinen Materialbahnen, insbesondere Papierbahnen bedruckt, deren Breite ein Vielfaches der Breite des fertigen Druckerzeugnisses beträgt. Um aus der bedruckten Bahn das fertige Druckerzeugnis herzustellen, ist es notwendig, diese Bahn in eine Mehrzahl von Teilbahnen zu zerschneiden, die zunächst parallel zueinander geführt werden, die aber übereinandergelegt werden müssen, um dann zum fertigen Druckerzeugnis, meist durch Falzen in Längs- und Querrichtung und Querschneiden, weiterverarbeitet zu werden. Beim Querschneiden der übereinandergelegten Materialbahnen ist es wichtig, dass Druckseiten auf den einzelnen Materialbahnen exakt in Phase zueinander ausgerichtet sind, so dass beim Querschneiden alle Materialbahnen jeweils an einer Grenze zwischen zwei Seiten durchtrennt werden. Zu diesem Zweck werden Registerwalzen eingesetzt, deren Verstellbarkeit es ermöglicht, die Länge des Weges einer Materialbahn durch die Wendestangenanordnung jeweils so einzustellen, dass auf den verschiedenen Bahnen Seiten, die zu einer Signatur verarbeitet werden sollen, exakt übereinander zu liegen kommen.In rotary printing machines, material webs, in particular paper webs, are printed in general, the width of which is a multiple of the width of the finished printed product. In order to produce the finished printed product from the printed web, it is necessary to cut this web into a plurality of partial webs, which are initially guided parallel to one another, but which have to be placed one above the other, in order to then produce the finished printed product, usually by folding lengthways and Cross direction and cross cutting to be processed. When cross-cutting the superimposed material webs, it is important that the printed pages on the individual material webs are exactly in phase with each other so that when cross-cutting all material webs are cut at a border between two sides. For this purpose, register rollers are used, the adjustability of which makes it possible to adjust the length of the path of a material web through the turning bar arrangement in such a way that pages which are to be processed for a signature come to lie exactly one above the other on the various webs.
Ein Beispiel einer solchen Wendestangenanordnung ist aus US 37 34 487 A bekannt. Diese Wendestangenanordnung umfasst eine erste Wendestange, die quer zu einer Zufuhrrichtung der umzulenkenden Materialbahn verschiebbar ist, sowie zwei Registerwalzen und eine Registerwalze. Die Registerwalze ist in einer unterhalb der Wendestange liegenden Ebene verschiebbar. Wenn eine große Zahl von Materialbahnen übereinandergelegt werden soll, so wird hierzu ein Stapel von übereinander angeordneten Wendestangenanordnungen eingesetzt. Es genügt jedoch bereits eine geringe Zahl von übereinanderzulegenden Materialbahnen, damit dieser Stapel bei der bekannten Wendestangenanordnung übermannshoch wird, was ihre Wartung und das Einziehen der Materialbahnen bei einem Auftragswechsel erheblich verkompliziert.An example of such a turning bar arrangement is known from US 37 34 487 A. This turning bar arrangement comprises a first turning bar, which is displaceable transversely to a feed direction of the material web to be deflected, as well as two register rollers and one register roller. The register roller can be moved in a plane below the turning bar. If a large number of material webs are to be placed on top of one another, a stack of one above the other is used for this purpose Turning bar arrangements used. However, a small number of material webs to be placed one on top of the other is already sufficient for this stack to be man-high in the known turning bar arrangement, which considerably complicates their maintenance and the drawing in of the material webs when a job is changed.
Durch die DE 38 16 900 A1 ist eine Einrichtung zum Versetzen von schmalen Papierbahnen in Form von Teilpapierbahnen bekanntgeworden.DE 38 16 900 A1 has disclosed a device for moving narrow paper webs in the form of partial paper webs.
Die DE-AS 17 61 899 zeigt höhenversetzte Wendestangen.DE-AS 17 61 899 shows vertically offset turning bars.
Die US 37 34 487 A zeigt zwei dreieckartig angeordnete Wendestangen, von denen eine Materialbahn auf eine Registerwalze führbar ist.The US 37 34 487 A shows two triangularly arranged turning bars, of which a material web can be guided on a register roller.
Die EP 07 84 590 B1 zeigt eine Wendeeinrichtung, bei der eine Führungswalze und die Wendestangen unterschiedlichen Durchmesser aufweisen. Die unter 90° zueinander angeordneten Wendestangen weisen gleichen Durchmesser auf.EP 07 84 590 B1 shows a turning device in which a guide roller and the turning bars have different diameters. The turning bars arranged at 90 ° to each other have the same diameter.
Der Erfindung liegt die Aufgabe zugrunde, eine Wendestangenanordnung und Verfahren zum Umlenken einer Warenbahn zu schaffen.The invention has for its object to provide a turning bar arrangement and method for deflecting a web.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 , 2, 10 oder 11 gelöst.The object is achieved by the features of claim 1, 2, 10 or 11.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass die Bauhöhe der Wendestangenanordnung klein gehalten werden kann, so dass die Zahl der Wendestangenanordnungen, die innerhalb einer vorgegebenen Bauhöhe übereinander montiert werden können, vergrößert ist. So kann die Zahl von Materialbahnen, die in einem Stapel von Wendestangenanordnungen übereinandergelegt werden können, vergrößert werden, ohne dass dafür der Stapel eine Höhe haben muss, die es einer Bedienungsperson schwierig macht, einzelne Wendestangenanordnungen des Stapels zu erreichen, um diese zu warten oder eine Materialbahn einzuziehen.The advantages that can be achieved with the invention consist in particular in that the overall height of the turning bar arrangement can be kept small, so that the number of turning bar arrangements that can be mounted one above the other within a predetermined overall height is increased. In this way, the number of material webs that can be superimposed in a stack of turning bar arrangements can be increased without the stack having to have a height that is one Makes it difficult for the operator to reach individual turn bar arrangements of the stack in order to maintain them or to draw in a material web.
Ein zwischen der ersten Wendestange und der Registerwalze verlaufender Abschnitt der Bahn definiert eine erste Ebene, die bei den herkömmlichen Wendestangenanordnungen im wesentlichen horizontal ist. Da die Wendestange und die Registerwalze, betrachtet aus einer zu dieser Ebene senkrechten Richtung, nicht überlappen, können sie, betrachtet aus einer zu der Ebene parallelen Richtung, überlappend angeordnet werden, so dass die Bauhöhe reduziert werden kann.A portion of the web extending between the first turner bar and the registration roller defines a first plane which is substantially horizontal in the conventional turner bar assemblies. Since the turning bar and the register roller, viewed from a direction perpendicular to this plane, do not overlap, they can be arranged to overlap, viewed from a direction parallel to the plane, so that the overall height can be reduced.
Eine besonders effektive Nutzung des zur Verfügung stehenden Bauvolumens ergibt sich, wenn die erste Wendestange und die Registerwaize auf einer gleichen Seite dieser ersten Ebene angeordnet sind.A particularly effective use of the available construction volume results if the first turning bar and the register roller are arranged on the same side of this first level.
Wenn die Registerwaize einen größeren Durchmesser als die erste Umlenkstange aufweist, so kann die um die Umlenkstange und die Registerwalze herumgeführte Materialbahn die Umlenkstange kreuzend abgeführt werden, ohne dass hierfür zusätzliche Umlenkelemente erforderlich sind.If the register roller has a larger diameter than the first deflecting rod, the material web which is guided around the deflecting rod and the register roller can be removed crossing the deflecting rod without additional deflecting elements being required for this.
Für eine Wendestangenanordnung mit zur Einlaufrichtung der Bahn paralleler Auslaufrichtung wird eine zweite Wendestange benötigt, und die Materialbahn ist zweckmäßigerweise der Reihe nach um die erste Wendestange, die Registerwalze und die zweite Wendestange herumschlingbar.A second turning bar is required for a turning bar arrangement with an outlet direction parallel to the running-in direction of the web, and the material web can expediently be looped around the first turning bar, the register roller and the second turning bar.
Wenn wenigstens eine der zwei Wendestangen aus einer zu der anderen Wendestange parallelen Orientierung in eine orthogonale Orientierung umstellbar ist, so erlaubt dies, die Wendestangenanordnung wahlweise mit paralleler oder mit antiparalleler Ein- und Auslaufrichtung zu betreiben. Eine schnelle und exakte Umstellung der Orientierung der umstellbaren Wendestange wird erreicht, wenn die Wendestange um eine Achse drehbar ist, die die Wendestange in einem Abstand von einem ihrer Längsenden schneidet, und an diesem Längsende eine Markierung angebracht ist, die in der parallelen bzw. der orthogonalen Orientierung mit jeweils einer von zwei komplementären Markierungen an einem Träger der Wendestange in Deckung bringbar ist. So genügt es, beim Umstellen der Wendestange die Deckungsgleichheit der Markierungen zu überprüfen, um sicher zu sein, dass die Wendestange exakt winkeleingestellt ist.If at least one of the two turning bars can be converted from an orientation parallel to the other turning bar into an orthogonal orientation, this allows the turning bar arrangement to be operated either with a parallel or with an anti-parallel inlet and outlet direction. A quick and exact change in the orientation of the reversible turning bar is achieved if the turning bar is rotatable about an axis that intersects the turning bar at a distance from one of its longitudinal ends, and a mark is attached to this longitudinal end that is in the parallel or orthogonal orientation with one of two complementary markings on a support of the turning bar can be made to coincide. It is therefore sufficient to check the congruence of the markings when moving the turning bar to be sure that the turning bar is set precisely at the angle.
Zusätzlich vereinfacht ist das exakte Einstellen der Wendestange dann, wenn die Markierungen eine Raumform aufweisen und in formschlüssigen Eingriff bringbar sind. Bei einer solchen Konstruktion garantiert bereits der Eingriff der Markierungen eine exakte Ausrichtung der Wendestange, ohne dass die Ausrichtung von einer Bedienungsperson aufwendig überprüft werden muss.The exact setting of the turning bar is also simplified when the markings have a spatial shape and can be brought into positive engagement. With such a construction, the engagement of the markings already guarantees an exact alignment of the turning bar without the alignment having to be checked laboriously by an operator.

The second turning bar 06 has at its longitudinal end 11 a complementary marking in the form of a recess which is shaped in such a way that it enables a positive engagement of one of the markings 13. By suitably adjusting the position of the markings 13 it can be ensured that the second turning bar 06 in its position shown in FIG. 1 is exactly parallel to the first turning bar 07 or, after pivoting the second turning bar 06 by 180 ° about the axis of the shaft 09 and engage the markings 13 is oriented exactly orthogonal to the first turning bar 07.
Die Träger 03; 04 weisen jeweils einen Anschlußstutzen 08 für Druckluft auf, die durch Bohrungen im Träger 03 oder 04 in die Wendestange 06 bzw. 07 geleitet wird und durch Bohrungen an der Umfangsfläche der Wendestange 06 bzw. 07 austritt, um ein Luftkissen zwischen der Wendestange 06; 07 und einer um sie herumgeschlungenen Materialbahn 22 zu bilden.The carrier 03; 04 each have a connection piece 08 for compressed air which is passed through bores in the carrier 03 or 04 into the turning bar 06 or 07 and exits through bores on the peripheral surface of the turning bar 06 or 07 in order to provide an air cushion between the turning bar 06; 07 and a material web wrapped around it 22 form.
Jeweils seitlich außerhalb der Seitengestelle 01 sind auf der Seite der ersten Wendestange 07 eine Registerwalze 14 und auf der Seite der zweiten Wendestange 06 eine Umlenkwalzenanordnung 16 montiert. Die Registerwalze 14 ist an einem an einer Schiene 17 verschiebbaren Gleitstein 18 montiert. Ein mit dem Gleitstein 18 fest verbundener Gewindekörper 19 ist mit einer Gewindestange 21 im Eingriff, die durch einen (nicht dargestellten) Motor drehantreibbar ist, um die Registerwalze 14 in Richtung des Doppelpfeils P zu verschieben. Die Registerwalze 18 ist außerhalb jeweils einer von dem jeweiligen Seitengestell zugehöriger Druckeinheiten festgelegten Ebene und außerhalb eines zwischen den Ebenen liegenden Raumes angeordnet.A register roller 14 is mounted on the side of the first turning bar 07 and on the side of the second turning bar 06 a deflecting roller arrangement 16 is mounted laterally outside the side frames 01. The register roller 14 is mounted on a sliding block 18 which can be displaced on a rail 17. A threaded body 19 which is fixedly connected to the sliding block 18 is in engagement with a threaded rod 21 which can be driven in rotation by a motor (not shown) in order to shift the register roller 14 in the direction of the double arrow P. The register roller 18 is arranged outside a level defined by the respective side frame associated printing units and outside a space lying between the levels.
Die Materialbahn 22 ist in der Fig. 1 transparent dargestellt; lediglich ihre Ränder sind durch dick durchgezogene Linien herausgehoben. Die Materialbahn 22 ist der Reihe nach um die zweite Wendestange 06, die Umlenkwalzenanordnung 16, die Registerwalze 14 und die erste Wendestange 07 herumgeschlungen. Für die Zwecke der vorliegenden Beschreibung wird angenommen, dass sie in Richtung eines Pfeils T bewegt wird; selbstverständlich wäre auch eine Bewegung in entgegengesetzter Richtung möglich. Ein einlaufender Abschnitt 23 erstreckt sich vom Eingang der Wendestangenanordnung bis zur zweiten Wendestange 06. Wie insbesondere in Fig. 2 zu erkennen ist, umschlingt die Materialbahn 22 die zweite Wendestange 06 von oben nach unten, erreicht die Umlenkwalzenanordnung 16, wird dort um 180° umgelenkt und verläuft in einem geringen Abstand von der Unterseite der zweiten Wendestange 06 quer durch die gesamte Wendestangenanordnung bis hin zur Oberseite der Registerwaize 14. Von der Unterseite der Registerwalze 14 erstreckt sich ein Abschnitt 26 der Materialbahn 22 in einer Ebene E zur Unterseite der ersten Wendestange 07. Die Materialbahn 22 umschlingt die erste Wendestange 07 von unten nach oben, so dass ein auslaufender Abschnitt 24 der Materialbahn 22 schließlich ausgehend von der Oberseite der Wendestange 07 die Wendestangenanordnung verlässt. Wie man leicht sieht, ermöglicht die Anordnung der Umlenkwalzenanordnung 16 und der Registerwalze 14 seitlich versetzt jenseits der Seitengestelle 01 und außerhalb des Bewegungsbereiches der Wendestangen 06, 07 entlang der Führungsprofile 02, die Bauhöhe der Wendestangenanordnung gering zu halten. Da der Durchmesser der Registerwalze 14 größer als der der ersten Wendestange 07 ist, können beide auf der gleichen Seite der Ebene E angeordnet sein, was zu einer weiteren Reduzierung der Bauhöhe beiträgt. Da sowohl die Registerwalze 14 als auch die erste Wendestange 07 oberhalb der Ebene E liegen, die durch den sich zwischen Registerwalze 14 und erster Wendestange 07 erstreckenden Abschnitt 26 der Materialbahn 22 definiert ist, kann der Höhenunterschied zwischen einlaufendem und auslaufendem Abschnitt 23, 24 noch geringer gehalten werden, als es der Bauhöhe der Wendestangenanordnung entspricht.The material web 22 is shown transparently in FIG. 1; only their edges are highlighted by thick solid lines. The material web 22 is wound in order around the second turning bar 06, the deflecting roller arrangement 16, the register roller 14 and the first turning bar 07. For the purposes of the present description, it is assumed that it is moved in the direction of an arrow T; of course, movement in the opposite direction would also be possible. An incoming section 23 extends from the entrance of the turning bar arrangement to the second turning bar 06. As can be seen in particular in FIG. 2, the material web 22 wraps around the second turning bar 06 from top to bottom, reaches the deflecting roller arrangement 16, is deflected there by 180 ° and runs at a short distance from the underside of the second turning bar 06 across the entire turning bar arrangement to the top of the register roller 14. A section 26 of the material web 22 extends in a plane E to the underside of the first turning bar 07 from the bottom of the register roller 14 The material web 22 wraps around the first turning bar 07 from bottom to top, so that a tapering section 24 of the material web 22 finally leaves the turning bar arrangement starting from the top of the turning bar 07. As can be easily seen, the arrangement of the deflection roller arrangement 16 and the register roller 14 laterally offset beyond the side frames 01 and outside the range of movement of the turning bars 06, 07 along the guide profiles 02 enables the overall height of the turning bar arrangement to be kept low. Since the diameter of the register roller 14 is larger than that of the first turning bar 07, both can be arranged on the same side of the plane E, which contributes to a further reduction in the overall height. Since both the register roller 14 and the first turning bar 07 lie above the plane E, which is defined by the section 26 of the material web 22 extending between the register roller 14 and the first turning bar 07, the height difference between the incoming and outgoing section 23, 24 can be even smaller be kept as it corresponds to the height of the turning bar arrangement.
Fig. 3 zeigt stark schematisiert einen Stapel, in dem eine Mehrzahl von Wendestangenanordnungen 27 vom in Fig. 1 und 2 gezeigten Typ übereinander angeordnet sind, gesehen aus Richtung des Pfeils IV in Fig. 1. Der Stapel umfasst hier vier übereinanderliegende Wendestangenanordnungen 27, ihre Zahl kann aber auch größer oder kleiner sein. Jeder Wendestangenanordnung 27 ist eine Spannwalzenanordnung 28 zum Gespannthalten zweiter Materialbahnen 22; 29 zugeordnet, die von einer (nicht gezeigten) Schneideinrichtung parallel zugeführt werden. Die Materialbahn 22 wird über die Wendestangenanordnung 27 zu einer ersten Umlenkwalze 31 geführt, die zweite Materialbahn 29 geht von der Spannwalzenanordnung 28 direkt zu einer Umlenkwalze 32. Mit Hilfe der Wendestangenanordnung 27 wird der seitliche Versatz zwischen den zwei Materialbahnen 22; 29 ausgeglichen, so dass diese mit exakt überlappenden Rändern und, durch geeignete Einstellung der Position der Registerwalze 14, auch in Phase miteinander einem (nicht gezeigten) Falzapparat zum Falzen und Schneiden zugeführt werden können. Fig. 4 zeigt eine zweite Ausgestaltung der Wendestangenanordnung, gesehen in der gleichen Perspektive wie in Fig. 2. Bei der Ausgestaltung der Fig. 4 wird der einlaufende Abschnitt 23 der Materialbahn 22 an die Unterseite der zweiten Wendestange 06 herangeführt, umschlingt diese von unten nach oben, umrundet dann von oben nach unten eine Umlenkwalze 33, die die Umlenkwalzenanordnung 16 aus Fig. 2 ersetzt, erreicht die in Richtung des Pfeils P verschiebbare Registerwalze 14 und verläuft von dort an wie mit Bezug auf Fig. 2 beschrieben. Der Höhenunterschied zwischen einlaufendem und auslaufendem Abschnitt 23 bzw. 24 ist bei dieser Variante minimal.FIG. 3 shows, in a highly schematic manner, a stack in which a plurality of turning bar arrangements 27 of the type shown in FIGS. 1 and 2 are arranged one above the other, viewed from the direction of arrow IV in FIG. 1. The stack here comprises four superposed turning bar arrangements 27, their However, the number can also be larger or smaller. Each turning bar arrangement 27 is a tensioning roller arrangement 28 for tensioning second material webs 22; 29 assigned, which are fed in parallel by a cutting device (not shown). The material web 22 is guided via the turning bar arrangement 27 to a first deflecting roller 31, the second material web 29 goes from the tensioning roller arrangement 28 directly to a deflecting roller 32. With the help of the turning rod arrangement 27, the lateral offset between the two material webs 22; 29 compensated so that they can be fed with a precisely overlapping edges and, by suitably adjusting the position of the register roller 14, also in phase with one another (not shown) for folding and cutting. FIG. 4 shows a second embodiment of the turning bar arrangement, seen in the same perspective as in FIG. 2. In the embodiment of FIG. 4, the incoming section 23 of the material web 22 is brought up to the underside of the second turning bar 06 and wraps around it from below above, then circles from top to bottom a deflecting roller 33, which replaces the deflecting roller arrangement 16 from FIG. 2, reaches the register roller 14, which is displaceable in the direction of arrow P, and runs from there as described with reference to FIG. 2. The height difference between the incoming and outgoing sections 23 and 24 is minimal in this variant.
Fig. 5 zeigt eine Ansicht einer dritten Ausgestaltung der Wendestangenordnung in einer Perspektive analog der der Fig. 2 und 4. Wie bereits bei der zweiten Ausgestaltung der Fig. 4 sind hier Elemente, die Elementen der ersten Ausgestaltung entsprechen und mit Bezug auf Fig. 1 und 2 bereits beschrieben sind, mit gleichem Bezugszeichen bezeichnet und nicht erneut beschrieben. Bei dieser dritten Ausgestaltung ist die Bauhöhe der Wendestangenanordnung weiter reduziert, indem beide Wendestangen 06; 07 in einer gleichen Ebene E angeordnet sind. Einlaufender und auslaufender Abschnitt 23; 24 befinden sich auf gleichem Niveau. Die (in der Fig. 5 nicht sichtbaren) Träger 03; 04 sind an einem einzigen Führungsprofil 02 montiert. Während bei den zwei zuvor beschriebenen Varianten die zwei Wendestangen 06; 07 beliebig nahe aneinander herangerückt werden können und sogar übereinander hinweg verschoben werden können, ist dies bei der Variante der Fig. 5 nicht möglich. Eine wesentliche Einschränkung in der Brauchbarkeit ist damit jedoch nicht verbunden, da Materialbahnen 22, die mit Hilfe der Wendestangenanordnung übereinandergelegt werden sollen, in den meisten Fällen aus einer einheitlichen Bahn durch Längsschneiden erhaltene Teilbahnen sind, die, um sie übereinander legen zu können, um wenigstens ihre eigene Breite verschoben werden müssen. Der hierfür erforderliche Abstand der Wendestangen 06; 07 kann auch bei dieser dritten Ausgestaltung leicht eingestellt werden. Um die Ausgestaltung der Fig. 5 zum Parallelverschieben einer Bahn wahlweise in entgegengesetzte Richtungen gebrauchen zu können, genügt es, dass beide Wendestangen 06; 07 so wie mit Bezug auf Fig. 1 für die zweite Wendestange 06 beschrieben, umstellbar sind, so dass die Wendestangenanordnung in ihr Spiegelbild überführbar ist.FIG. 5 shows a view of a third embodiment of the turning bar arrangement in a perspective analogous to that of FIGS. 2 and 4. As in the second embodiment of FIG. 4, here are elements that correspond to elements of the first embodiment and with reference to FIG. 1 and 2 have already been described, are designated by the same reference symbol and are not described again. In this third embodiment, the overall height of the turning bar arrangement is further reduced by both turning bars 06; 07 are arranged in the same plane E. Incoming and outgoing section 23; 24 are on the same level. The carrier 03 (not visible in FIG. 5); 04 are mounted on a single guide profile 02. While in the two variants described above, the two turning bars 06; 07 can be moved as close to one another as desired and can even be moved one above the other, this is not possible in the variant of FIG. 5. However, this does not imply a significant limitation in usability, since material webs 22 which are to be superimposed with the aid of the turning bar arrangement are in most cases partial webs obtained from a uniform web by longitudinal cutting, which, in order to be able to overlay them, are at least their own width need to be shifted. The required distance between the turning bars 06; 07 can also be easily adjusted in this third embodiment. In order to be able to use the configuration of FIG. 5 for shifting a web in parallel in either direction, it suffices that both turning bars 06; 07 as with reference to Fig. 1 for the second turning bar 06 are described, convertible so that the turning bar arrangement can be converted into its mirror image.
Alle Wendestangen 06; 07, Umlenkstangen 16; 33 und die Registenvalzen 14 sind vorzugsweise als Kragarm ausgebildet, d. h. lediglich ein Ende ist gelagert. All turning bars 06; 07, deflecting rods 16; 33 and the register tabs 14 are preferably designed as a cantilever arm, ie only one end is supported.
