Description

Die vorstehende Erfindung betrifft eine Einrichtung zum automatischen Einfuehren einer Papierbahn in eine Wendestangenvorrichtung, die zwischen einer Schneidvorrichtung und dem Falz- und Heftapparat einer Druckmaschine angeordnet sind.The above invention relates to a device for automatically inserting a paper web into a turning bar device, which are arranged between a cutting device and the folder and stapler of a printing press.

Es ist dem Fachmann bekannt, dass nach der Schneidvorrichtung, mit der die Papierbahn (die z. B. in einer Rotationsdruckmaschine bedruckt wurde) in einzelne Baender aufgetrennt wird und vor einem Falz- und Heftapparat, der am Ende der Rotationsdruckmaschine angeordnet ist, sogenannte Wendestangen vorgesehen sind.It is known to the person skilled in the art that after the cutting device with which the paper web (which was printed, for example, in a rotary printing press) is cut into individual strips and before a folding and stitching apparatus which is arranged at the end of the rotary printing press, so-called turning bars are provided.

Diese Wendestangen bestehen im wesentlichen aus orientierbaren und in ihrer Lage einstellbaren Rollen, die die Aufgabe haben, den einzelnen Papierbaendern nach der Schneidvorrichtung unterschiedliche Bewegungsrichtungen zu verleihen und nach dem Schnitt ein geordnetes Zusammenfuegen der Papierbahnen zu ermoeglichen, um dadurch vor der Falz- und Hefteinrichtung eine Vielzahl von parallel zueinander angeordneten Papierbahnen zu erhalten, die in der gewuenschten Reihenfolge und Anordnung zueinander liegen.These turning bars consist essentially of orientable and positionally adjustable rollers, which have the task of giving the individual paper strips different directions of movement after the cutting device and, after the cut, of allowing the paper webs to be joined together in order to provide one in front of the folding and stitching device To obtain a large number of paper webs arranged parallel to one another, which lie in the desired sequence and arrangement with respect to one another.

Es ist dem Fachmann weiter bekannt, dass das Einfuehren der getrennten, einzelnen Papierbahnen, in die Wendestangenvorrichtung, einen grossen Zeitaufwand sowie mehrere Arbeitskraefte bedingt, da es erforderlich ist, jede einzelne Papierbahn um eine zugeordnete Rolle der Wendestangenvorrichtung zu legen und die Papierbahnen um mehrere Umlenkrollen und Ausgleichsrollen zu fuehren, die erforderlich sind, um eine genaue und sichere Fuehrung jeder einzelnen Papierbahn bis zum Heft- und Falzapparat zu gewaehrleisten.It is further known to the person skilled in the art that the introduction of the separate, individual paper webs, in the turning bar device, a large amount of time and several manpower, since it is necessary to put each individual paper web around an assigned role of the turning bar device and to guide the paper webs around several deflection rollers and compensating rollers, which are required to achieve a to ensure precise and safe guidance of each individual paper web up to the stapling and folding apparatus.

Es ist daher verstaendlich, dass jeder Abriss der Papierbahn und jeder neue Einfaedelvorgang der Papierbahnen in die Wendestangenvorrichtung, wegen der zahlreichen von Hand vorzunehmenden Vorgaenge in nachteiliger Weise die Fertigungskosten der Zeitschrift beeinflusst.It is therefore understandable that each tear off of the paper web and each new threading process of the paper webs into the turning bar device, because of the numerous manual operations, adversely affects the production costs of the magazine.

Aufgabe der vorstehenden Erfindung ist es, die Nachteile des Standes der Technik zu vermeiden und eine Vorrichtung vorzuschlagen, mit der die Papierbahnen von der Schneidvorrichtung bis zum Falz- und Heftapparat automatisch in die Wendestangenvorrichtung einfuehrbar sind.The object of the above invention is to avoid the disadvantages of the prior art and to propose a device with which the paper webs from the cutting device to the folder and stapler can be automatically introduced into the turning bar device.

Diese Aufgabe wird erfindungsgemaess dadurch erreicht, dass jeder Wendestange eine Kette, ein Seil oder ein aehnliches Zugmittel zugeordnet ist, das einen geschlossenen Ring bildet und sich teilweise entlang der Bewegungsbahn des Papierstreifens von der Schneidvorrichtung bis zum Falz- und Heftapparat erstreckt, und dass jede Kette oder jedes Seil mit einem steuerbaren Antriebsmittel in Verbindung steht und Einrichtungen zum Klemmen des Randes der einzufuehrenden Papierbahn aufweist.This object is achieved according to the invention in that each turning bar is assigned a chain, a rope or a similar traction device, which forms a closed ring and extends partially along the path of movement of the paper strip from the cutting device to the folder and stapler, and that each chain or each Rope is connected to a controllable drive means and has devices for clamping the edge of the paper web to be inserted.

Mit einer Vorrichtung dieser Art ist es moeglich, die einzelnen Papierbahnen automatisch um die einzelnen Wendestangen herum in die Vorrichtung einzufuehren. Dies kann durch einen einzigen Bedienungsmann erfolgen. Es ist lediglich erforderlich, die einzelnen Papierbahnen zu erfassen und deren Rand mit den, an den einzelnen Ketten oder Zugseilen angeordneten Klemmvorrichtungen zu verbinden, um somit durch Antrieb der Kette oder des Zugseils die Papierbahnen in die einzelnen Wendestangenvorrichtungen einzufuehren.With a device of this type, it is possible to automatically insert the individual paper webs into the device around the individual turning bars. This can be done by a single operator. It is only necessary to grasp the individual paper webs and to connect their edge to the clamping devices arranged on the individual chains or pulling ropes, in order to thus introduce the paper webs into the individual turning bar devices by driving the chain or the pulling rope.

Die erfindungsgemaesse Vorrichtung wird nun genauer beschrieben und anhand eines Ausfuehrungsbeispiels in den Zeichnungen dargestellt.The device according to the invention will now be described in more detail and illustrated in the drawings using an exemplary embodiment.

Es zeigen:

  • Fig. 2 das rechte Teilstueck der Wendestangenvorrichtung mit dem Falzapparat;
  • Fig. 3 das linke Teilstueck der Wendestangenvorrichtung mit Ausgleichs- und Umlenkrollen;
  • Fig. 4 eine Seitenansicht der Wendestangenvorrichtung.
Show it:
  • Figure 1 shows the central piece of a turning bar device, equipped with the feed devices according to the invention.
  • Figure 2 shows the right part of the turning bar device with the folder.
  • 3 shows the left part of the turning bar device with compensating and deflecting rollers;
  • Fig. 4 is a side view of the turning bar device.

Wie der Fig. 1 zu entnehmen ist, ist die gesamthaft mit 1 gekennzeichnete Wendestangenvorrichtung zwischen einer bekannten Schneidvorrichtung 2 und einem Falzapparat 3 (nicht dargestellt) angeordnet.As can be seen from FIG. 1, the turning bar device, identified overall by 1, is arranged between a known cutting device 2 and a folder 3 (not shown).

Durch die Schneidvorrichtung 2 wird die bedruckte Papierbahn in einzelne Papierstreifen, die zueinander parallel liegen, aufgeteilt. Die Anzahl der Papierstreifen ist veraenderbar. Die aufgetrennten Papierstreifen sind in der Zeichnung mit 4,5,6,7,8,9 gekennzeichnet.By means of the cutting device 2, the printed paper web is divided into individual paper strips which are parallel to one another. The number of paper strips can be changed. The separated paper strips are marked in the drawing with 4,5,6,7,8,9.

Nach der Schneidvorrichtung 2 ist fuer jeden Papierstreifen eine Wendestange 10,11,12,13,14 bzw. 15 vorgesehen. In bekannter Weise besteht jede Wendestange (10 bis 15) aus einer Rolle, die in verschiedenen Lagen angeordnet werden kann (fuer die Wendestangengruppe 10 ist die zugeordnete Rolle mit 16 gekennzeichnet). Unter Verwendung dieser, in ihrer Lage einstellbar vorgesehenen Rollen, ist es moeglich, die Laufrichtung der Papierbahnen zu aendern, so koennen diese Bahnen z.B. in Horizontalrichtung nach rechts oder in Horizontalrichtung nach links umgelenkt werden.After the cutting device 2, a turning bar 10, 11, 12, 13, 14 and 15 is provided for each paper strip. In a known manner, each turning bar (10 to 15) consists of a roll that can be arranged in different positions (for the turning bar group 10, the assigned roll is identified by 16). Using these rolls, which can be adjusted in their position, it is possible to change the running direction of the paper webs, so these webs can e.g. in the horizontal direction to the right or in the horizontal direction to the left.

Die Papierstreifen 4 bis 9 werden nach den Wendestangen 10 bis 15 um Ausgleichs- und Umlenkzylinder gefuehrt, die mit 17,18,19,20,21 und 22 gekennzeichnet sind. Diese Umlenk- und Ausgleichszylinder haben die Aufgabe, den zugeordneten Papierstreifen praezise und gesteuert durch die gesamte Wendestangenvorrichtung zu fuehren, um zu ermoeglichen, dass am Ende der Wendestangenvorrichtung alle Papierstreifen in geordneter Reihenfolge vorliegen, parallel zueinander angeordnet sind und dem Falz- und Heftapparat 3 zufuehrbar sind.The paper strips 4 to 9 are guided after the turning bars 10 to 15 around compensating and deflecting cylinders, which are identified by 17, 18, 19, 20, 21 and 22. These deflection and compensation cylinders have the task of guiding the assigned paper strip precisely and in a controlled manner through the entire turning bar device in order to enable that at the end of the turning bar device all paper strips are in an ordered order, are arranged parallel to one another and can be fed to the folding and stitching apparatus 3.

Jeder Wendstangenvorrichtung sind zwischen der Schneidevorrichtung 2 und dem Falz- und Heftapparat 3 Ausgleichs- und Umlenkzylinder zugeordnet, Einrichtungen, die an sich fuer Wendestangenvorrichtungen bekannt sind. Waehrend vor dem Einlauf der Wendestangenvorrichtung 1 ueblicherweise die Schneidvorrichtung 2 vorgesehen ist, ist am Auslauf der Wendestangenvorrichtung 1 in bekannter Weise ein Falz- und Heftapparat 3 vorgesehen, der nicht genauer dargestellt ist.Each turning bar device between the cutting device 2 and the folder and stapler 3 compensating and deflecting cylinders are assigned, devices that are known per se for turning bar devices. While the cutting device 2 is usually provided in front of the entry of the turning bar device 1, a folding and stapling device 3 is provided at the outlet of the turning bar device 1, which is not shown in more detail.

Um die Papierstreifen 4 bis 9 automatisch in die Wenstangenvorrichtung 1 einfuehren zu koennen und die Papierstreifen automatisch um die entsprechenden Rollen 10 bis 15 der Wendestangen sowie um die entsprechenden Ausgleichszylinder 17 bis 22 und die Umlenk- und Ausgleichszylinder, die fuer derartige Einrichtungen bekannt sind, zu legen, ist erfindungsgemaess vorgesehen, dass entlang der Bewegungsbahn der Papierstreifen 4 bis 9 im Inneren der Wendestangenvorrichtung 10,11,12,13,14,15 Ketten oder Zugseilen angeordnet sind.In order to be able to automatically insert the paper strips 4 to 9 into the Wenstangenvorrichtung 1 and the paper strips automatically around the corresponding rollers 10 to 15 of the turning bars as well as around the corresponding compensation cylinders 17 to 22 and the deflection and compensation cylinders, which are known for such devices it is provided according to the invention that chains or traction cables are arranged along the movement path of the paper strips 4 to 9 inside the turning bar device 10, 11, 12, 13, 14, 15.

Diese Zugmittel 24,25,26,27,28 und 29 sind in den Zeichnungen schematisch mit unterschiedlich gestrichelten Linien dargestellt.These traction means 24, 25, 26, 27, 28 and 29 are shown schematically in the drawings with different lines Lines shown.

Die Ketten oder Seile 24 - 29 bilden jeweils einen geschlossenen Kreis. In den beigefuegten Zeichnungen ist dargestellt, dass die Wendestangenvorrichtung 1 einen ersten Seilzug 24 aufweist, dem ein Seilzug 25, ein Seilzug 26, ein Seilzug 27, ein Seilzug 28 und ein Seilzug 29 folgen. Jeder Seilzug 24 - 29 erstreckt sich in Form eines geschlossenen Kreises von einer Stelle, die nach der Schneidvorrichtung 2 vorgesehen ist, bis zu einer Stelle, die vor der Falz- und Hefteinrichtung 3 zu liegen kommt.The chains or ropes 24-29 each form a closed circle. The attached drawings show that the turning bar device 1 has a first cable 24, which is followed by a cable 25, a cable 26, a cable 27, a cable 28 and a cable 29. Each cable 24 - 29 extends in the form of a closed circle from a point which is provided after the cutting device 2 to a point which comes to lie in front of the folding and stitching device 3.

Wenn man beruecksichtigt, dass sich das Funktionsprinzip der einzelnen Seilzuege 24 - 29, die als geschlossener Ring angeordnet sind, in gleicher Weise fuer jede einzelne Wendestange 10 - 15 wiederholt, ist verstaendlich, dass im folgenden Text nur ein Seilzug 26 genauer beschrieben wird.If one takes into account that the functional principle of the individual cable pulls 24 - 29, which are arranged as a closed ring, is repeated in the same way for each individual turning bar 10 - 15, it is understandable that only one cable pull 26 is described in more detail in the text below.

Wie den Zeichnungen 1, 2 und 3 zu entnehmen ist, ist der Seilzug 26 so angeordnet, dass er einen geschlossenen Kreis bildet, der sich entlang der gesamten Bewegungsbahn des Papierstreifens (von der Schneidvorrichtung 2 bis zum Falz- und Heftapparat 3) erstreckt. In der Naehe der Wendestangengruppe 12 wird das Zugseil 26 unter Verwendung von genuteten Laufraedern 30 gefuehrt. Das Zugseil 26 verlaeuft dann nach rechts und wird von Umlenkraedern 31 gefuehrt, um sich weiter auf die rechte Seite der Wendestangenvorrichtung zu erstrecken. Wie der Fig. 2 zu entnehmen ist, wird das Zugseil 26 ueber ein Laufrad 32 gefuehrt, das mit einer Ausgleichsvorrichtung 19 verbunden ist, um nach einem genuteten Fuehrungsrad 23 die Falz- und Heftvorrichtung 3 zu erreichen.As can be seen from the drawings 1, 2 and 3, the cable 26 is arranged so that it forms a closed circle which extends along the entire path of movement of the paper strip (from the cutting device 2 to the folder and stapler 3). In the vicinity of the turning bar group 12, the pull cable 26 is guided using grooved wheels 30. The pull cable 26 then runs to the right and is guided by deflection wheels 31 in order to extend further to the right side of the turning bar device. How to Fig. 2 too can be seen, the pull rope 26 is guided over an impeller 32 which is connected to a compensating device 19 in order to reach the folding and stapling device 3 after a grooved guide wheel 23.

Anschliessend unter Zuhilfenahme von Laufrollen 34 und 35 sowie Umlenkrollen 36 wird das Zugseil 26 auf der Aussenseite der Wendestangenvorrichtung nach oben umgelenkt, und nach einem Umlenkrad 36 durchquert das Zugseil in Horizontalrichtung die Oberseite der Wendestangenvorrichtung, um auf die linke Seite der Wendstangenvorrichtung (Fig. 3) zu gelangen. Nach Verlassen der Umlenkraeder 38 und 39 sowie nach Verlassen eines Fuehrungsrades 40 und einer Gruppe von Ausgleichsraedern 41, erreicht das Zugseil 26 erneut die Umlenkraeder 30.Subsequently, with the aid of rollers 34 and 35 and deflection rollers 36, the pull cable 26 on the outside of the turning bar device is deflected upward, and after a deflection wheel 36, the pull rope crosses the top side of the turning bar device in the horizontal direction in order to move to the left side of the turning bar device (FIG. 3 ) to get. After leaving the deflection wheels 38 and 39 and after leaving a guide wheel 40 and a group of compensating wheels 41, the traction cable 26 again reaches the deflection wheels 30.

Durch diesen geschlossenen Kreislauf, der durch die Umlenkraeder und Ausgleichsraeder 30 - 41 festgelegt wird, ist es moeglich, mit dem Zugseil 26 die gesamte Bewegungsbahn des bedruckten Papierstreifens in der Wendestangenvorrichtung 1 abzufahren, das heisst von der Schneidvorrichtung 2 bis zum Falz- und Heftapparat 3.Due to this closed circuit, which is determined by the deflection wheels and compensating wheels 30-41, it is possible to traverse the entire trajectory of the printed paper strip in the turning bar device 1 with the pull rope 26, that is to say from the cutting device 2 to the folding and stitching device 3 .

Mit besonderem Vorteil ist vorgesehen, dass z. B. das Umlenkrad 40 unter Zwischenschaltung eines Federmittels 42 (oder eines Pneumatikzylinders) gelagert ist. Diese Bauteile haben die Aufgabe als Daempfungs- und Ausgleichsmittel fuer das Zugseil oder die Kette 26 zu wirken.It is particularly advantageous that z. B. the deflection wheel 40 is mounted with the interposition of a spring means 42 (or a pneumatic cylinder). These components have the task of damping and compensating means for the traction cable or chain 26 Act.

Um dem Zugseil oder der Kette 26 eine Bewegung in der gewuenschten Richtung und mit der gewuenschten Geschwindigkeit zu verleihen, ist es vorteilhfat, die Kette 26 ueber einen steuerbaren Motor, z. B. unter Zwischenschaltung eines Umlenkrades 43 anzutreiben. Natuerlich koennen auch andere Antriebe vorgesehen sein.In order to give the traction rope or chain 26 a movement in the desired direction and at the desired speed, it is advantageous to use a controllable motor, e.g. B. with the interposition of a deflection wheel 43. Of course, other drives can also be provided.

Was den Antrieb des Zugseils 26 anbetrifft, so scheint eine guenstige Ausfuehrungsform darin zu bestehen, dass der Antrieb des Zugseils mechanisch von der Antriebsvorrichtung fuer den Papiervorlauf der Rotationsdruckmaschine abgeleitet wird, wobei die Moeglichkeit einer unabhaengigen Steuerung vorgesehen sein sollte.As far as the drive of the pull cable 26 is concerned, a favorable embodiment seems to be that the drive of the pull cable is derived mechanically from the drive device for the paper feed of the rotary printing press, whereby the possibility of independent control should be provided.

Um in optimaler Weise den fuer die Fuehrung und Lagerung der Zugseile 24,25,26,27,28 und 29 notwendigen Raum zu nuetzen, ist vorgesehen, dass in der Naehe der Vorschubrollen 34,35 des Falz- und Heftapparats eine Haelfte der Zugseile 24,25 und 26 nach rechts umgelenkt wird, um dann die Oberseite der Wendestangenvorrichtung 1 zu erreichen, wogegen die Zugseile 27, 28, 29 nach links umgelenkt werden, um die Unterseite der Wendestangenvorrichtungen zu erreichen.In order to optimally use the space required for guiding and storing the pull cables 24, 25, 26, 27, 28 and 29, provision is made for a half of the pull cables 24 to be provided in the vicinity of the feed rollers 34, 35 of the folder and stapler , 25 and 26 is deflected to the right in order to then reach the top of the turning bar device 1, whereas the pulling cables 27, 28, 29 are turned to the left in order to reach the bottom of the turning bar devices.

Jedes Zugseil 24,25,26,27,28 und 29 weist eine Anzahl von Klemmvorrichtungen 24',25',26',27',28' und 29' auf, die es ermoeglichen, den jeweiligen vorderen Rand der Papierstreifen 4, 5, 6,7, 8 und 9, die automatisch in die Wendestangenvorrichtung 1 einzufuehren sind, zu klemmen. Durch Antrieb der Zugseile koennen somit die Papierstreifen 4 - 9 von der Schneidvorrichtung 2 zum Falz- und Heftapparat 3 gefoerdert werden.Each traction cable 24, 25, 26, 27, 28 and 29 has a number of clamping devices 24 ', 25', 26 ', 27', 28 'and 29' which enable the respective front edge of the Clamp paper strips 4, 5, 6,7, 8 and 9, which are to be inserted automatically into the turning bar device 1. By driving the pulling ropes, the paper strips 4 - 9 can thus be conveyed from the cutting device 2 to the folder and stapler 3.

Um ein Loesen zwischen den nicht dargestellten Klemmeinrichtungen und den Papierbahnen 4 bis 9 zu erreichen, ist nach den Zufuehrrollen 34, 35 eine Vorrichtung zum Oeffnen der zangenfoermigen Klemmeinrichtungen vorzusehen. Diese Vorrichtung koennte z. B. aus einer Kurvenscheibe oder einer Steuerkufe bestehen, die auf das bewegliche Teil der Klemmzange einwirkt, um diese zu oeffnen, damit der Vorderrand des eingezogenen Papierstreifens freigegeben wird.In order to achieve a loosening between the clamping devices (not shown) and the paper webs 4 to 9, a device for opening the pincer-shaped clamping devices must be provided after the feed rollers 34, 35.
