Description

Die Erfindung betrifft einen Falzapparat mit einem Schneidleisten und Nutenbalken aufweisenden Punktur- und Falzmesserzylinder, an dem ein mit Messern ausgestatteter Schneidzylinder angestellt ist, und einem dem Punktur- und Falzmesserzylinder nachgeordneten Falzklappenzylinder.The invention relates to a folding apparatus with a cutting and folding bar having puncture and folding knife cylinder, on which a cutting cylinder equipped with knives is employed, and a folding jaw cylinder arranged downstream of the puncturing and folding knife cylinder.

Aus dem Fachbuch "Atlas des Zeitungs- und Illustrationsdruckes" von Alexander Braun, Polygraphverlag, Frankfurt am Main, 1960, Seite 69 ist ein Falzapparat der vorangehend beschriebenen Gattung bekannt. Im gleichen Fachbuch (Seite 75, rechte Spalte) wird auch darauf hingewiesen, daß in Falzapparaten beim Auftreten von sogenannten Stoppern eine Gefahr für die Steuerorgane besteht, weshalb beispielsweise automatisch wirkende Sicherheitskupplungen im Antrieb des Falzapparates dafür sorgen, daß die Falzzylindergruppe und gleichzeitig der Antriebsmotor der Maschine abgeschaltet werden. Derartige Stopper oder auch sonstige Papieranhäufungen bzw. ein Papierstau kann insbesondere zwischen dem Punktur- und Falzmesserzylinder und dem Falzklappenzylinder auftreten da beispielsweise sich die zugeschnittenen auf dem Punktur- und Falzmesserzylinder befindlichen und nur durch Punkturen bzw. Nadeln gehaltenen Druckexemplare lösen können, wobei ein gelöstes Exemplar durch nachfolgende Exemplare weggerissen werden kann, wodurch es zu einem Stau bzw. zu einer Papieranhäufung in dem Spalt zwischen Falzklappenzylinder und Punktur- und Falzmesserzylinder (Zentrale A) kommt, was, wie vorangehend dargelegt, zu Beschädigungen führen kann. Auch durch Umschlagen der Bogen kann es zu derartigen Problemen kommen. Zur Vermeidung der vorgenannten Gefahren ist es auch allgemein bekannt, beim Auftreten von Stoppern oder Papierstau, einen Zylinder abzuschwenken, so daß der Spalt zwischen Punktur- und Falzmesserzylinder und Falzklappenzylinder ausreichend groß wird. Die Überwachung und das Verschwenken eines Zylinders ist jedoch relativ aufwendig und die Ansprechzeit außerdem verhältnismäßig lang.A folder of the type described above is known from the specialist book "Atlas of Newspaper and Illustration Printing" by Alexander Braun, Polygraph Verlag, Frankfurt am Main, 1960, page 69. In the same technical book (page 75, right column) it is also pointed out that in the folders there is a danger to the control elements when so-called stoppers occur, which is why, for example, automatically acting safety clutches in the drive of the folder ensure that the folding cylinder group and at the same time the drive motor of the Machine be switched off. Such stoppers or other accumulations of paper or a paper jam can occur in particular between the puncture and folding knife cylinder and the folding jaw cylinder since, for example, the printed copies which are cut on the puncturing and folding knife cylinder and held only by punctures or needles can be released, with one released copy can be torn away by subsequent copies, resulting in a jam or an accumulation of paper in the gap between the folding jaw cylinder and the puncture and folding knife cylinder (center A), which, as explained above, can lead to damage. Turning the sheets over can also cause such problems. To avoid the aforementioned dangers, it is also generally known to pivot a cylinder when stoppers or paper jams occur, so that the gap between the puncturing and folding knife cylinder and folding jaw cylinder becomes sufficiently large. However, monitoring and pivoting a cylinder is relatively complex and the response time is also relatively long.

Aufgabe der vorliegenden Erfindung ist es, mit einfachen und kostengünstigen Mitteln die Gefahren bzw. Folgen von Stoppern oder eines Papierstaues zu vermeiden. Diese Aufgabe wird dadurch gelöst, daß zwischen in Umfangsrichtung benachbarten Falzklappen des Falzklappenzylinders jeweils sich auch in Achsrichtung des Falzklappenzylinders erstreckende Gruben oder Abflachungen vorgesehen sind, in der Weise, daß beim Überrollen des Spaltes zwischen dem Falzklappenzylinder und dem Punktur- und Falzmesserzylinder jeweils eine Schneidleiste bzw. ein Nutenbalken einer Grube oder einer Abflachung gegenüberliegt. Es ist vorteilhaft die Gruben oder Abflachungen mittels elastischen Elementen abzudecken, die vorzugsweise nebeneinander liegend angeordnet sind. Diese Elemente können aus Federbandstahl oder aus einem geeigneten elastischen Kunststoff hergestellt werden. Ohne die Verschwenkung eines Zylinders können gemäß der Erfindung also die durch Papierstau oder Stopper auftretenden Gefahren eliminiert werden, da durch die Gruben oder Abflachungen zwischen den Falzklappen des Falzklappenzylinders quasi eine Spaltvergrößerung auftritt, durch die sich der Papierstau ohne weiteres hindurchbewegen kann. Werden die Gruben oder Abflachungen durch die elastischen Elemente abgedeckt, so können diese im Falle eines Stoppers oder einer Papieranhäufung soweit nachgeben, so daß es zu keiner Beschädigung kommt.The object of the present invention is to avoid the dangers or consequences of stoppers or a paper jam using simple and inexpensive means. This object is achieved in that in the circumferential direction adjacent jaws of the jaw cylinder also pits or flats extending in the axial direction of the jaw cylinder are provided, in such a way that when the gap between the jaw cylinder and the puncture and folding knife cylinder a cutting bar or respectively a grooved bar is opposite a pit or a flat. It is advantageous to cover the pits or flats by means of elastic elements, which are preferably arranged next to one another. These elements can be made from spring steel or from a suitable elastic plastic. Without the pivoting of a cylinder, the dangers arising from paper jams or stoppers can thus be eliminated according to the invention, since the pits or flattenings between the jaws of the jaw cylinder virtually increase the gap through which the paper jam can easily move. If the pits or flattened areas are covered by the elastic elements, they can yield in the event of a stopper or a pile of paper so that there is no damage.

Da die Punktur- und Falzmesserzylinder üblicherweise mit einer Durchmesserverstellung versehen bzw. ausgerüstet sind, die in exzentrisch gelagerten Bolzen geführt ist, können im Falle eines Papierstaus in der Zentrale zwischen Falzklappenzylinder und Punktur- und Falzmesserzylinder diese Segmente nachgeben. Im Bereich des bzw. der Nutenbalken hingegen ist bedingt durch die Funktion des Nutenbalkens eine stabile Bauweise erforderlich. Bekanntlich muß der Nutenbalken ein Widerlager bzw. eine Abstützung für die Abschneidleiste bieten, wenn mit Hilfe des Schneidmessers im Schneidzylinder jeweils ein Bogen geschnitten wird. Da der Bereich des Nutenbalkens bzw. der Schneidleiste stets zwischen zwei Falzklappen des benachbarten Falzklappenzylinders den gemeinsamen Spalt der beiden Zylinder überrollt, kann in erfindungsgemäßer Weise das durch Papierhäufung oder Stopper auftretende Problem mit der Erfindung in überraschend einfacher und wirkungsvoller Weise gelöst werden.Since the puncture and folding knife cylinders are usually provided or equipped with a diameter adjustment which is guided in eccentrically mounted bolts, these segments can yield in the event of a paper jam in the center between the jaw cylinder and the puncturing and folding knife cylinders. In the area of the grooved bar or bars, however, a stable construction is required due to the function of the grooved bar. As is known, the grooved bar must provide an abutment or a support for the cutting bar if an arc is cut in each case with the aid of the cutting knife in the cutting cylinder. Since the area of the grooved bar or the cutting bar always rolls over the common gap of the two cylinders between two folding jaws of the adjacent folding jaw cylinder, the problem arising from paper accumulation or stoppers can be solved in accordance with the invention with the Invention be solved in a surprisingly simple and effective manner.

Dem in Fig. 1 dargestellten Falzapparat 1 wird eine Bedruckstoffbahn 2 über Zugwalzen 3, 4 in üblicher Weise zugeführt. Die Bedruckstoffbahn 2 gelangt zwischen einen Schneidzylinder 5 und einen Punktur- und Falzmesserzylinder 6. Der Schneidzylinder 5 weist hier zwei gegenüberliegende Messer 7 auf. Der Punktur- und Falzmesserzylinder 6 ist an seiner Peripherie mit mehreren Schneidleisten 8 und Punkturen 9 ausgestattet. Selbstverständlich können auch im Rahmen der Erfindung anstelle der Punkturen 9 Greifer verwendet werden, um jeweils den Anfang der zugeführten Bedruckstoffbahn 2 zu erfassen, bevor jeweils der Zuschnitt eines Exemplares zwischen einem Messer 7 und einer Schneidleiste 8 erfolgt. Im hier dargestellten Ausführungsbeispiel nicht dargestellte, aus der Bedruckstoffbahn 2 zugeschnittene Exemplare werden über einen entsprechenden Umfangsbereich des Punktur- und Falzmesserzylinders 6 geführt, wonach mit Hilfe der Falzmesser 10 des Punktur- und Falzmesserzylinders 6 die Falzbildung erfolgt, in dem die Falzmesser 10 die auf dem Punktur- und Falzmesserzylinder 6 liegenden Exemplare in Falzklappen 13 des benachbarten bzw. nachgeordneten Falzklappenzylinders 12 stoßen. Die gefalzten Exemplare gelangen dann in üblicher Weise entlang eines Pfeiles 15 in ein Schaufelrad 14 und von diesem auf eine Bandleitung 16.The folding apparatus 1 shown in FIG. 1 is fed a printing material web 2 via pulling rollers 3, 4 in the usual way. The printing material web 2 comes between a cutting cylinder 5 and a puncturing and folding knife cylinder 6. The cutting cylinder 5 has two opposite knives 7 here. The puncture and folding knife cylinder 6 is equipped on its periphery with several cutting strips 8 and punctures 9. Of course, instead of the punctures 9, grippers can also be used within the scope of the invention in order to grasp the beginning of the supplied printing material web 2 each time before a copy is cut between a knife 7 and a cutting bar 8. In the embodiment shown here, not shown, cut from the printing material web 2, specimens are guided over a corresponding circumferential area of the puncturing and folding knife cylinder 6, after which, with the help of the folding knife 10 of the puncturing and folding knife cylinder 6, the folding takes place, in which the folding knife 10 is on the Puncture and folding knife cylinders 6 encounter specimens lying in jaws 13 of the adjacent or subordinate jaw cylinder 12. The folded ones Specimens then get in the usual way along an arrow 15 into a paddle wheel 14 and from there onto a belt line 16.

Wie bereits beschrieben, kann im Bereich der Zentrale A zwischen den Zylindern 6 und 12 ein Papierstau auftreten, der eventuell eine Beschädigung an den Zylindern 6, 12 hervorrufen würde, wenn sich dieser zwischen den Zylindern 6, 12 hindurchbewegt. Da üblicherweise die bei 17 angedeutete Durchmesserverstellung eine Vergrößerung des Spaltes zwischen den Zylindern 6, 12 ermöglicht, wie vorangehend beschrieben wurde, ist in diesen Bereichen die Gefahr einer Beschädigung quasi gebannt.As already described, a paper jam may occur in the area of the center A between the cylinders 6 and 12, which would possibly cause damage to the cylinders 6, 12 if it moves between the cylinders 6, 12. Since the diameter adjustment indicated at 17 usually enables an enlargement of the gap between the cylinders 6, 12, as described above, the risk of damage is virtually eliminated in these areas.

Hingegen im Bereich einer jeden Schneidleiste 8, die durch Nutenbalken bzw. Nutenbalken 11 jeweils gestützt sind, ist eine derartige Vergrößerung des Spaltes zwischen den Zylindern 6, 12 bei bekannten Falzapparaten nicht möglich, denn die Schneidleisten 8 und Nutenwalzen 11 können nicht "nachgiebig" ausgebildet werden, infolge der Funktion, die sie erfüllen müssen. Hierdurch entsteht eine erhebliche Gefahr, daß beim Durchgang des Papierstaues zwischen den Zylindern 6, 12 zu einem Zeitpunkt, zu dem die Schneidleisten 8 bzw. Nutenbalken 11 den Spalt durchlaufen, Teile des Falzapparates 1 zerstört werden können. Erfindungsgemäß wird deshalb in den den Schneidleisten 8 bzw. Nutenbalken 11 gegenüberliegenden Bereichen (das ist jeweils der Bereich zwischen benachbarten Falzklappen 13), der Mantel des Falzklappenzylinders mit Gruben 18 oder mit Abflachungen 20 versehen, wie die Fig. 3, 4 zeigen. Dadurch ergibt sich beim Überlaufen der Gruben 18 bzw. der Abflachungen 20 jeweils auch eine Vergrößerung des Spaltes zwischen den Zylindern 6, 12, so daß der Papierstau gefahrlos den Spalt zwischen den Zylindern 6, 12 passieren kann.In contrast, in the area of each cutting bar 8, which are each supported by grooved bars or grooved bars 11, such an enlargement of the gap between the cylinders 6, 12 is not possible with known folding apparatuses, because the cutting bars 8 and grooved rollers 11 cannot be “compliant” due to the function they have to perform. This creates a considerable risk that parts of the folder 1 can be destroyed when the paper jam passes between the cylinders 6, 12 at a time when the cutting bars 8 or grooved bars 11 pass through the gap. According to the invention, therefore, in the areas opposite the cutting strips 8 or grooved bars 11 (this is in each case the area between adjacent folding jaws 13), the jacket of the folding jaw cylinder is provided with pits 18 or with flats 20, as FIGS. 3, 4 show. This results in an enlargement of the gap between the cylinders 6, 12 when the pits 18 or the flats 20 overflow, so that the paper jam can safely pass the gap between the cylinders 6, 12.

Falls die kreiszylindrische Mantelkontur des Falzklappenzylinders 12 beibehalten werden soll, können die Gruben 18 bzw. die Abflachungen 20 mit elastischen Abdeckelementen 19, 21 versehen werden, beispielsweise in Form von nebeneinander liegenden Elementen aus Federbandstahl oder aus einem geeignet elastischen Kunststoff, so daß die in Längsrichtung des Falzklappenzylinders 12 verlaufenden Gruben 18 bzw. Abflachungen 20 quasi überbrückt werden. Die jeweils dreifach vorhandenen Teile 13, 18, 19 wurden in Fig. 1 nur einmal aus Platzgründen mit Bezugszeichen vesehen.If the circular cylindrical jacket contour of the jaw cylinder 12 is to be maintained, the pits 18 or the flats 20 can be provided with elastic cover elements 19, 21, for example in the form of adjacent elements made of spring steel or from a suitable elastic plastic, so that the pits 18 or flats 20 extending in the longitudinal direction of the jaw cylinder 12 are virtually bridged. The parts 13, 18, 19 which are present in triplicate were only provided once in FIG. 1 with reference numerals for reasons of space.

Die Länge der Gruben 18 bzw. der Abflachungen 20 in Umfangsrichtung des Falzklappenzylinders 12 gesehen, kann durch Versuche ermittelt werden oder es kann der längstmöglichste Umfangsabschnitt jeweils zwischen zwei benachbarten Falzklappen 13 zur Erzeugung der Gruben 18 herangezogen werden, wie dies etwa bei der Ausführung gemäß Fig. 4 der Fall ist. Dadurch ist sichergestellt, daß in jedem Fall auftretende Stopper oder Papieranhäufungen den Spalt zwischen den Zylindern 6, 12 passieren können, ohne daß eine Beschädigungsgefahr auftritt.The length of the pits 18 or of the flats 20 in the circumferential direction of the jaw cylinder 12 can be determined by experiment or the longest possible circumferential section between two adjacent jaws 13 can be used to produce the pits 18, as is the case, for example, in the embodiment according to FIG 4 is the case. This ensures that any stoppers or accumulations of paper that occur can pass through the gap between the cylinders 6, 12 without the risk of damage.
