Description

Die Erfindung betrifft eine Einzugsvorrichtung für Rollen-Rotationsdruckmaschinen zum Einziehen von Materialbahnen mit einem aus flexiblem Vollmaterial bestehenden Einzugselement, das seitlich des Einzugsweges für die Materialbahn entlang einer rohrförmigen Führung verschiebbar ist.The invention relates to a feed device for web-fed rotary printing presses for pulling material webs with a feed element made of flexible solid material, which is displaceable along the tubular guide along the feed path for the material web.

Aus der DE-Patentschrift 2241 127 ist eine Vorrichtung zum Einziehen von Materialbahnen in Rotationsdruckmaschinen bekannt, bei der längs unterschiedlicher seitlicher Einzugswege, die durch außerhalb des Walzenbereichs liegende Führungen und Weichen gebildet sind, entweder ein aus flexiblem Vollmaterial bestehendes Einzugselement endlicher Längenausdehnung in Form eines flachen, durchgehenden Stahlbandes oder eine vielgliedrige Rollenkette in den Führungen entlang des eingestellten Einzugsweges verschiebbar ist. Bedingt durch die Form bzw. Ausgestaltung dieser Einzugselemente ist eine Biegung, abgesehen von einer gewissen Verwindungsmöglichkeit, nur in einer Ebene senkrecht zur Längserstreckung möglich, so daß komplizierte Einzugswege, wie z. B. durch den Wendestangenaufbau, hierdurch praktisch nicht realisiert werden können.From DE-Patent 2241 127 a device for pulling material webs in rotary printing presses is known, in which along different lateral feed paths, which are formed by guides and switches located outside the roller area, either a feed element made of flexible solid material of finite length extension in the form of a flat one , continuous steel belt or a multi-link roller chain in the guides along the set feed path is displaceable. Due to the shape or design of these feed elements, a bend, apart from a certain twisting possibility, is only possible in one plane perpendicular to the longitudinal extension, so that complicated feed paths, such as. B. by the turning bar structure, this can not be practically realized.

Die Aufgabe der Erfindung ist es, die bekannte Einzugsvorrichtung für Rollen-Rotationsdruckmaschinen der eingangs definierten Art so weiterzubilden, daß auch sehr komplizierte, d. h. stark verwundene Einzugswege realisierbar sind.The object of the invention is to develop the known feed device for web-fed rotary printing presses of the type defined at the outset in such a way that even very complicated, i.e. H. heavily twisted feed paths can be realized.

Diese Aufgabe wird bei der Erfindung dadurch gelöst, daß das Einzugselement einen runden oder polygonalen Massivquerschnitt aufweist, so daß der Biegewiderstand in allen Richtungen quer zur Längsachse des Einzugselements annähernd gleich groß ist.This object is achieved in the invention in that the pull-in element has a round or polygonal solid cross-section, so that the bending resistance is approximately the same in all directions transverse to the longitudinal axis of the pull-in element.

Durch das in allen Richtungen biegbare erfindungsgemäße Einzugselement können die Führungen erfindungsgemäße Einzugselement können die Führungen für das Einzugselement zur Festlegung des Einzugsweges individuell und ohne richtungsmäßige Einschränkungen entsprechend den vorhandenen räumlichen Gegebenheiten einer Druckmaschine gewählt werden.Due to the pull-in element according to the invention, which can be bent in all directions, the guides according to the invention can select the guides for the pull-in element to determine the feed path individually and without directional restrictions in accordance with the available spatial conditions of a printing press.

Fig. 1 zeigt eine bekannte Rollen-Offsetrotationsdruckmaschine, in der die vielfältigen und zum Teil äußerst komplizierten Bahnführungen gezeigt sind. Die in Druckwerken 1, 2, 3 und 4 bedruckten, von Rollensternen 5, 6, 7, 8 zugeführten Papierbahnen 9, 10, 11, 12 werden über nicht näher bezeichnete Führungs- und Wendestangen nach entsprechender Längsteilung einer Falzvorrichtung 13 zugeführt, in der die Zuschneidung und Falzung der bedruckten Bahnen 9 bis 12 vorgenommen wird. Entsprechend den jeweiligen Anforderungen bezüglich der zu druckenden Farben auf der Vorder- und Rückseite der Papierbahnen 9 bis 12 erfolgt der Einzug der Papierbahnen 9 bis 12 zwischen bestimmten, nicht näher bezeichneten Zylindern der Druckwerke 1 bis 4. Der Übersicht halber wurde bei der in Fig. 1 gezeigten Druckmaschine darauf verzichtet, Druck- und Feuchtwerke sowie weitere notwendige Einrichtungen darzustellen. Mit Fig. 1 soll veranschaulicht werden, in welch mannigfaltiger und komplizierter Art bei modernen Druckmaschinen, deren Umfang häufig über ein Vielfaches der in Fig. 1 gezeigten Maschine hinausgeht, die Papierbahnführungen möglich sind.Fig. 1 shows a known web offset printing press, in which the varied and sometimes extremely complicated web guides are shown. The paper webs 9, 10, 11, 12 printed in printing units 1, 2, 3 and 4, fed by roller stars 5, 6, 7, 8, are fed via guide and turning bars (not further specified) after a corresponding longitudinal division of a folding device 13, in which the The printed sheets 9 to 12 are cut and folded. In accordance with the respective requirements with regard to the colors to be printed on the front and back of the paper webs 9 to 12, the paper webs 9 to 12 are drawn in between certain cylinders of the printing units 1 to 4, which are not described in any more detail. 1 shown printing machine does not represent printing and dampening units and other necessary facilities. 1 is intended to illustrate the varied and complicated nature of the paper web guides in modern printing presses, the scope of which often exceeds a multiple of the machine shown in FIG. 1.

Besonders bei Bahnrissen ergeben sich bei derartigen Maschinen schwerwiegende Störungen. Um die Einzugswege für ein Einzugselement den jeweiligen gegebenen örtlichen Verhältnissen anpassen zu können, wird gemäß der Erfindung das in Fig. 2 und 3 gezeigte als Einzugselement dienende Zugseil 14 verwendet. Anstelle eines Seils oder einer Spirale mit rundem Querschnitt kann auch ein Einzugselement mit einem polygonalem Querschnitt verwendet werden. Wesentlich ist es, daß das Einzugselement nach allen Seiten biegbar ist, so daß keine Einengung der möglichen Einzugswege durch die Form des Einzugselements entsteht.In the case of web breaks in particular, such machines result in serious malfunctions. In order to be able to adapt the pull-in paths for a pull-in element to the given local conditions, the pulling cable 14 shown in FIGS. 2 and 3 serves as the pull-in element. Instead of a rope or a spiral with a round cross-section, a pull-in element with a polygonal cross-section can also be used. It is essential that the pull-in element is bendable on all sides so that the possible pull-in paths are not restricted by the shape of the pull-in element.

Das Zugseil 14 wird in einem Führungsrohr 15, das entsprechend den gewünschten Einzugswegen in der Druckmaschine verlegt ist, geführt.The pull cable 14 is guided in a guide tube 15 which is laid in the printing press in accordance with the desired feed paths.

Das Zugseil 14 weist einen Schlepphaken 16 auf, der durch in den Führungsrohren 15 vorgesehene Schlitze 17 herausragt und an den die einzuziehende Papierbahn gegebenenfalls über ein Seil angehängt werden kann.The traction cable 14 has a drag hook 16 which protrudes through slots 17 provided in the guide tubes 15 and to which the paper web to be drawn in can optionally be attached via a cable.

An Unterbrechungen zwischen verschiedenen Führungsrohren 15 greift mindestens ein Friktionsräderpaar 20, 21 an. Mindestens ein Rad, hier das Rad 21, besteht aus einer Rolle, z. B. aus Hartgummi, die durch eine Druckfeder 22 gegen das Zugseil 14 gepreßt wird. Dadurch ist eine sichere Führung des Zugseils 14 gewährleistet, wobei zwischen mehreren Friktionsräderpaaren eine Synchronisierung infolge der Schlupfmöglichkeit nicht erforderlich ist.At least one pair of friction wheels 20, 21 acts on interruptions between different guide tubes 15. At least one wheel, here the wheel 21, consists of a role, for. B. from Hard rubber, which is pressed by a compression spring 22 against the pull cable 14. This ensures reliable guidance of the traction cable 14, wherein synchronization between several pairs of friction wheels is not necessary due to the possibility of slipping.

Durch herkömmliche Befestigungslaschen 18 werden die Führungsrohre 15 an einer Maschinenseitenwand 19 oder an einer anderen gestellfesten Halterung in der Druckmaschine fixiert.The guide tubes 15 are fixed to a machine side wall 19 or to another frame-fixed holder in the printing press by means of conventional fastening tabs 18.

Fig. 4 zeigt in Weiterbildung der Erfindung eine Weiche 23, mit deren Hilfe das in einem Führungsrohr 24 geführte Einzugselement wahlweise in ein Führungsrohr 25 oder ein Führungsrohr 26 eingebracht werden kann. Für diese Steuerung wird ein mit einem Drehteller 27 verbundener Pneumatikzylinder 28 verwendet, der um einen Schwenkzapfen 29 drehbar ist.4 shows, in a further development of the invention, a switch 23 with the aid of which the pull-in element guided in a guide tube 24 can optionally be introduced into a guide tube 25 or a guide tube 26. A pneumatic cylinder 28, which is connected to a turntable 27 and can be rotated about a pivot pin 29, is used for this control.

Fig. 5 zeigt eine erweiterte Wahlmöglichkeit. Die hier gezeigte Weiche 30 bietet dem in dem Führungsrohr 31 ankommenden Einzugselement drei Wege an, nämlich das Führungsrohr 32, das Führungsrohr 33 oder das Führungsrohr 34, an. Die Auswahl der Wege erfolgt durch die Einstellung eines Drehtellers 35, der durch einen doppeltwirkenden Pneumatikzylinder 36 in drei Stellungen gebracht werden kann. Bei der dargestellten Stellung in Fig. 5 wird das Einzugselement geradlinig von dem Führungsrohr 31 zu dem Führungsrohr 33 geführt. In der linken Stellung des Pneumatikzylinders 36 erfolgt eine Weiterleitung zu dem Führungsrohr 32 und in der rechten Stellung zu dem Führungsrohr 34. Der zweiteilige, durch ein Zwischenstück 37 geteilte Pneumatikzylinder 36 ist zur Ausgleichung der Längendifferenz um einen Schwenkzapfen 38 drehbar.Fig. 5 shows an expanded option. The switch 30 shown here offers the pull-in element arriving in the guide tube 31 three ways, namely the guide tube 32, the guide tube 33 or the guide tube 34. The paths are selected by setting a turntable 35, which can be brought into three positions by a double-acting pneumatic cylinder 36. In the position shown in FIG. 5, the pull-in element is guided in a straight line from the guide tube 31 to the guide tube 33. In the left position of the pneumatic cylinder 36 there is a forwarding to the guide tube 32 and in the right position to the guide tube 34. The two-part pneumatic cylinder 36, which is divided by an intermediate piece 37, can be rotated about a pivot pin 38 to compensate for the length difference.

Fig. 6, 7 und 8 zeigen die Führungsmöglichkeit des Einzugselements 14 bzw. die Anordnung der Führungsrohre 15 um bzw. zwischen Seitenwänden 39 und 40 liegende Wendestangen 41 und 42. Bedingt durch die vorteilhafte Querschnittsform des Zugseils 14 ist eine individuelle Führung in verschiedensten Richtungen, Ebenen und Krümmungsradien möglich.6, 7 and 8 show the possibility of guiding the pull-in element 14 or the arrangement of the guide tubes 15 around or between turning walls 41 and 42 lying between side walls 39 and 40. Due to the advantageous cross-sectional shape of the pulling cable 14, individual guiding in various directions is possible, Planes and radii of curvature possible.

Fig. und 10 zeigen schematisch in Vorder-und Seitenansicht eine Antriebsvorrichtung für das Zugseil 14. In dieser wird das zwischen Führungsrohren 43 und 44 freiliegende Führungsseil 14 zwischen durch Zahnräder 45, 46 und 47 antreibbare Reibräder 48, 49 und einem Reibrad 50 in Längsrichtung angetrieben, d. h. geschoben. Durch die Reibräder 48, 49 wird dabei das Zugseil 14 um einen Teil des Umfangs des Reibrades 50 geführt, wodurch die Reib- und somit die Vorschubwirkung bezogen auf eine tangentiale Seilführung wesentlich verbessert wird. Durch entsprechende Vertiefungen - vorzugsweise mit halbkreisförmigem Querschnitt - am Umfang der Reibräder 48,49,50 für die Zugseilführung wird eine zusätzliche Verbesserung erzielt. Die Zahnräder 45, 46, 47 werden durch einen Motor 51 angetrieben.FIGS. 10 and 10 schematically show front and side views of a drive device for the pull cable 14. In this, the guide cable 14, which is exposed between guide tubes 43 and 44, is driven in the longitudinal direction between friction wheels 48, 49, which can be driven by gear wheels 45, 46 and 47, and a friction wheel 50 , d. H. pushed. The traction cable 14 is guided through part of the circumference of the friction wheel 50 by the friction wheels 48, 49, as a result of which the friction and thus the feed effect with respect to tangential cable guidance is significantly improved. Appropriate recesses - preferably with a semicircular cross-section - on the circumference of the friction wheels 48, 49, 50 for the traction cable guide provide an additional improvement. The gears 45, 46, 47 are driven by a motor 51.

In den Fig. 11 und 12 ist eine zweite Antriebsvorrichtung gezeigt, in der der zwischen Führungsrohren 52, 53 verlaufende Abschnitt des Zugseils 14 durch Reibräderpaare 54, 56 und 55, 57 antreibbar ist. Diese werden mit Hilfe eines Motors 58 über Zahnräder 59, 60, 61, 62 und 63 in Drehung versetzt.11 and 12 show a second drive device in which the section of the pulling cable 14 running between guide tubes 52, 53 can be driven by pairs of friction wheels 54, 56 and 55, 57. These are set in rotation by means of a motor 58 via gear wheels 59, 60, 61, 62 and 63.

Eine besonders wirkungsvolle Antriebsvorrichtung ist in den Fig. 13 und 14 dargestellt, mit der ein hohes Schubmoment auf das Zugseil übertragbar ist. Das z. B. aus einem Führungsrohr 64 austretende und in ein Führungsrohr 65 einlaufende Führungsseil 14 ist um ein Reibrad 71 geführt, an dessen Peripherie zwei Reibräder 70, 72 angeordnet sind. Die Reibräder 70, 71, 72 sind über Zahnräder 66, 67, 68 durch einen Motor 69 antreibbar. Zur besseren Seilführung ist um das Reibrad 71 ein Leitapparat 73 in Form eines Leitmantels vorgesehen. Durch die Umschlingung des Reibrades 71 wirkt sich die Funktion ef'''' bei der Berechnung des Reibwertes aus, wobei e die Basis des natürlichen Logarithmus, u, den materialspezifischen Reibwert und x den Umschlingungswinkel bedeutet.A particularly effective drive device is shown in FIGS. 13 and 14, with which a high thrust torque can be transmitted to the pull rope. The Z. B. emerging from a guide tube 64 and entering a guide tube 65 guide rope 14 is guided around a friction wheel 71, on the periphery of which two friction wheels 70, 72 are arranged. The friction wheels 70, 71, 72 can be driven by a motor 69 via gear wheels 66, 67, 68. For better cable guidance, a guide device 73 in the form of a guide jacket is provided around the friction wheel 71. By wrapping the friction wheel 71, the function ef '' '' has an effect on the calculation of the coefficient of friction, where e is the basis of the natural logarithm, u, the material-specific coefficient of friction and x the angle of wrap.
