Ein derartiges Falzwerk ist beispielsweise aus der DE 31 47 064 bekannt. Dabei ist zwischen zwei Seitenwänden eine Mehrzahl von Falzwalzen angeordnet, mit deren Hilfe ein einlaufendes Falzprodukt gefalzt wird. Am Ausgang des Falzwerkes ist darüber hinaus, wie bei Falzwerken üblich, eine sogenannte Ausführwalze angeordnet, die das gefalzte Produkt aus dem Falzwerk ausführt bzw. der nächsten Bearbeitungsstation zuführt. Der Ausführwalze vorgelagert ist üblicherweise ein Messerwellenpaar, mit dessen Hilfe ein Zuschnitt oder eine Perforierung des Falzproduktes erreicht werden kann. In dieser bekannten Anordnung ist also dem Messerwellenpaar in Papierlaufrichtung eine Ausführwalze nachgeordnet, die neben dem bloßen Zweck des Ausführens der Falzprodukte auch dazu benutzt werden kann, eine Ritz-, Schneide- oder Perforiereinrichtung zu tragen.Such a folder is known for example from DE 31 47 064. It is a plurality of folding rollers arranged between two side walls, with the help of them an incoming folded product is folded. At the exit of the folder, as usual with folding units, a so-called delivery roller is arranged, which is the folded Executes product from the folder or feeds it to the next processing station. The The leading roller is usually a pair of knife shafts, with the help of which Cutting or perforation of the folded product can be achieved. In this Known arrangement is a pair of knife shafts in the paper running direction Subordinate roller, which in addition to the mere purpose of executing the Folded products can also be used to make a score, cut or Perforator to wear.

Derartige Falzmaschinen haben jedoch den Nachteil, dass sie, bedingt durch den festen Einbau der Ausführwalzen in die Gehäusewände, nicht verändert werden können, sodass eine Anpassung des Falzwerkes auf unterschiedliche Kundenbedürfnisse nur schwer möglich ist.Such folding machines have the disadvantage, however, that they, due to the fixed Installation of the delivery rollers in the housing walls, can not be changed so that it is difficult to adapt the folder to different customer needs is possible.

Aufgabe der vorliegenden Erfindung ist es daher, die Variabilität eines Falzwerkes zu steigern.The object of the present invention is therefore to increase the variability of a folding unit increase.

Vorteilhafte Ausführungsformen und Weiterbildungen sind Gegenstand der nachgeordneten Ansprüche.
Das Vorsehen von Ausnehmungen in den Seitenwänden des Falzwerkes, die zur Aufnahme eines Bearbeitungselementes geeignet sind, hat eine Reihe von Vorteilen; denn damit wird es nun möglich, am Ausgang des Falzwerkes individuelle Bearbeitungsstationen vorzusehen. In den Ausnehmungen können unterschiedliche Einsätze angebracht werden, die den jeweiligen Anforderungen entsprechen.Advantageous embodiments and further developments are the subject of the subordinate claims.
The provision of recesses in the side walls of the folding mechanism, which are suitable for receiving a processing element, has a number of advantages; because it is now possible to provide individual processing stations at the exit of the folder. Different inserts can be fitted in the recesses to meet the respective requirements.

In einer bevorzugten Ausführungsform sind die beiden Ausnehmungen in den Seitenwänden einander gegenüber angebracht und weisen eine im wesentlichen gleiche Form auf. Zwischen den Ausnehmungen der Seitenwände wird ein Einsatz angebracht, der in Papierlaufrichtung schwenkbar ist. Sofern das Bearbeitungselement eine Ausführwalze ist, lässt sich diese durch einfache Schwenkung in Papierlaufrichtung ausklappen. Dies erleichtert den Zugang zu den dahinterliegenden Messerwellen erheblich, sodass deren Bestückung leicht geändert werden kann.In a preferred embodiment, the two recesses in the Sidewalls attached to each other and have a substantially the same Shape up. An insert is attached between the recesses in the side walls is pivotable in the paper running direction. If the processing element is a delivery roller it can be folded out by simply swiveling it in the direction of the paper. This makes it considerably easier to access the knife shafts behind, so that Equipment can be changed easily.

In Fig. 1 ist schematisch in perspektivischer Ansicht ein Ausschnitt eines erfindungsgemäßen Falzwerkes 10 gezeigt. Das Falzwerk 10 weist zwei einander gegenüberliegende Seitenwände 12 und 14 auf, an denen eine Mehrzahl von Walzen drehbar gelagert ist, von denen die Messerwellen 16 und 18 gezeigt ist. Die beiden Seitenwände 12 und 14 sind mit jeweils einer Ausnehmung 15, 17 versehen, so daß beidseitig in die jeweilige Ausnehmung passend ein Bearbeitungselement eingefügt werden kann. Obwohl die Form der Ausnehmungen 15 und 17 unterschiedlich sein kann, ist es vorteilhaft, wenn die Form der einander gegenüberliegenden Ausnehmungen gleich ist.In Fig. 1 is a schematic perspective view of a section of a Folding unit 10 according to the invention shown. The folder 10 has two each other opposite side walls 12 and 14 on which a plurality of rollers is rotatably supported, of which the cutter shafts 16 and 18 is shown. The two Side walls 12 and 14 are each provided with a recess 15, 17 so that a processing element can be inserted on both sides into the respective recess can. Although the shape of the recesses 15 and 17 can be different, it is advantageous if the shape of the opposing recesses is the same.

In Fig. 2 ist schematisch perspektivisch das erfindungsgemäße Falzwerk mit einem eingesetzten Bearbeitungselement 20 gezeigt. Das Bearbeitungselement 20 weist dabei zwei Seitenwände 22 und 24 auf, die in die Ausnehmungen 15 und 17 der Seitenteile 12 und 14 eingesetzt sind. Im vorliegendenden Beispiel weist die Bearbeitungsstation eine sogenannte Ausführwalze 26 auf, die das Papier in Papierlaufrichtung A ausführt und gegebenenfalls einer weiteren Bearbeitungsstation zuführt. Wie in Fig. 1 bereits gezeigt liegen hinter der Ausführwalze 26, also entgegen der Papierlaufrichtung, weitere Walzen, insbesondere die Messerwalzen 16 und 18, bei denen es erforderlich ist, die Bestückung in regelmäßigen Abständen zu überprüfen und gegebenenfalls zu ändern. Erfindungsgemäß ist es daher besonders vorteilhaft, die Bearbeitungsstation 20 so an den Rahmenteilen 12 und 14 des Falzwerkes zu befestigen, dass diese durch eine einfache Schwenkbewegung weggeklappt werden kann, so daß nach dem Wegschwenken der Zugang zu den Messerwellen 16 und 18 freigegeben wird.In Fig. 2 is a perspective view of the folder according to the invention with a used processing element 20 shown. The processing element 20 has two side walls 22 and 24, which in the recesses 15 and 17 of the side parts 12th and 14 are used. In the present example, the processing station has one so-called delivery roller 26, which executes the paper in the paper running direction A and optionally feeds another processing station. As already shown in Fig. 1 are further rollers behind the delivery roller 26, i.e. counter to the paper running direction, especially the knife rollers 16 and 18, where it is necessary to equip the check at regular intervals and change if necessary. According to the invention it is therefore particularly advantageous to process the processing station 20 on the frame parts 12 and 14 of the folder to attach that by a simple swivel movement can be folded away so that after swinging away access to the Knife shafts 16 and 18 is released.

In der schematischen Seitenansicht in Fig. 3 ist die Seitenwand 14 eines erfindungsgemäßen Falzwerkes 10 gezeigt. In der Seitenwand 14 ist die Ausnehmung 17 vorgesehen, in welche das Bearbeitungselement 20 um die Achse 28 schwenkbar eingebracht ist. Das Bearbeitungselement 20 weist eine Seitenwand 24 auf, die so geformt ist, daß sie in der Ausnehmung 17 Platz findet. Weiterhin ist in dem Bearbeitungselement 20 eine Ausführwalze 26 vorgesehen. Exemplarisch sind drei Schwenkpositionen S1, S2 und S3 des Bearbeitungselementes 20 gezeigt. Dabei repräsentiert die Schwenkposition S1 die vollständig in das Falzwerk eingebrachte Bearbeitungsstation 20. In dieser Position läßt sich die Bearbeitungsstation auch fest mit dem Walzwerk verbinden. Insbesondere zum Freigeben des Zuganges zu dem Messerwellenpaar 16, 18 läßt sich die Bearbeitungsstation 20 um die Achse 28 in Papierlaufrichtung, z. B. in die beiden Position S2 und S3 schwenken. Dabei kann eine Rasterung vorgesehen werden, die das Bearbeitungselement 20 in definierten Rasterabständen zwischen der Schwenkposition S1 und S3 hält. Außerdem kann das Element 20 auch mit Hilfe eines rasterlosen Mechanismus geschwenkt werden, der insbesondere ein Arretieren in den Schwenkpositionen S1 und S3 zuläßt. Sobald das Bearbeitungselement 20 in die Rasterposition S3 ausgeschwenkt ist, ist der Zugang zu dem Messerwellenpaar 16 und 18 frei.In the schematic side view in FIG. 3, the side wall 14 is one Folding unit 10 according to the invention shown. The recess 17 is in the side wall 14 provided, in which the machining element 20 is pivotable about the axis 28 is introduced. The processing element 20 has a side wall 24 which is shaped in this way is that it fits 17 in the recess. Furthermore is in the processing element 20 an output roller 26 is provided. Three swivel positions S1, S2 are exemplary and S3 of the processing element 20 are shown. The swivel position represents S1 the processing station 20 completely inserted into the folder. In this position the processing station is also firmly connected to the rolling mill. Especially for The processing station can be released for access to the pair of knife shafts 16, 18 20 about the axis 28 in the paper running direction, for. B. in the two positions S2 and S3 swing. In this case, a grid can be provided, which is the processing element 20 holds at defined grid intervals between the pivot position S1 and S3. In addition, the element 20 can also be pivoted using a rasterless mechanism be, which in particular allows locking in the pivot positions S1 and S3. As soon as the processing element 20 is pivoted into the grid position S3, the Access to the pair of cutter shafts 16 and 18 free.

Damit bietet das erfindungsgemäße Falzwerk den besonderen Vorteil, daß die Bestückung an den Messerwellen leicht geändert werden kann bzw. auch für andere Arbeiten ein erleichterter Zugriff möglich ist. Nach den Einstellarbeiten an dem Messerwellenpaar 16 und 18 wird die Arretierung des Bearbeitungselementes 20 wieder ausgerastet und das Bearbeitungselement wieder von der Position S3 in die Position S 1 zurück geschwenkt. Das Bearbeitungselement wird in dieser Position arretiert, insbesondere verschraubt und der Antrieb der Ausführwalze 26 wieder aktiviert. Dies kann beispielsweise dadurch erfolgen, daß die Ausführwalze 26 mit einem seitlichen Zahnrad versehen ist, welches in seinen Eingriffen positioniert wird. The folding mechanism according to the invention thus offers the particular advantage that the loading can be easily changed on the cutter shafts or for other work easier access is possible. After the adjustment work on the pair of knife shafts 16 and 18, the locking of the processing element 20 is disengaged again and that Machining element swung back from position S3 to position S1. The processing element is locked in this position, in particular screwed and the drive of the feed roller 26 is reactivated. This can be done, for example take place that the delivery roller 26 is provided with a side gear, which in his interventions are positioned.

Neben dem schwenkbaren Bearbeitungselement 20 kann das erfindungsgemäße Falzwerk auch eine Traverse 30 aufweisen. Auf diese Traverse 30 werden üblicherweise Zusatzelemente wie beispielsweise Abstreifer und Lichttaster aufgebracht. Vorteilhafter Weise wird die über dem Bearbeitungselement 20 liegende Traverse 30 ebenfalls schwenkbar ausgestattet, so daß auch mit dem Schwenken der Traverse 30 die Einstellarbeiten an den Messerwellen und an der Traverse selbst erleichtert werden können.In addition to the pivotable processing element 20, the folding unit according to the invention can also have a traverse 30. On this traverse 30 are usually Additional elements such as wipers and light sensors applied. More advantageous The crossbeam 30 lying over the processing element 20 also becomes like this equipped pivotable, so that even with the pivoting of the traverse 30 Adjustment work on the knife shafts and on the crossbar itself can be facilitated.

In einem weiteren Ausführungsbeispiel ist das erfindungsgemäße Falzwerk in Seitenansicht in Fig. 4 gezeigt. In der Seitenwand 14 des Falzwerkes ist ein Messerwellenpaar 16 und 18 drehbar gelagert, sowie eine Ausnehmung 17 vorgesehen, in welche ein Bearbeitungselement 32 eingesetzt ist, das eine Seitenwand 34, sowie ein Messerwellenpaar 36, 38 aufweist. Darüber hinaus ist in der Bearbeitungsstation 32 eine Ausführwalze 40 vorgesehen, die dazu dient, den aus dem Falzwerk auslaufenden Papierbogen auszuführen. Die Seitenwand 34 des Bearbeitungselementes 32 ist so geformt, daß sie in die Ausnehmung 17 der Seitenwand des Falzwerkes eingeführt und dort arretiert werden kann. Sie kann hierzu insbesondere einen Vorsprung aufweisen, der in die Ausnehmung 17 eingreift. Mit einem derartig ausgestalteten Bearbeitungselement 32 läßt sich die Variabilität des Falzwerkes deutlich steigern, da das nachgelagerte Messerwellenpaar 36 und 38 zusätzliche Bearbeitungselemente aufnehmen können, mit denen zusätzliche Nuten, Ritzen oder Perforierungen eingebracht werden können. Darüber hinaus ergibt sich in dieser Konstellation der Vorteil, daß sich das Bearbeitungselement 32 je nach Bedarf auch noch nachträglich an das Falzwerk anbringen läßt. Um den Abstand zwischen den Messerwellen des zweiten nachgelagerten Messerwellenpaares 36, 38 einstellen zu können, kann eine zusätzliche nachträglich, einzubauenden Walzenspalteinstellvorrichtung (nicht gezeigt) vorgesehen werden.In a further exemplary embodiment, the folding mechanism according to the invention is in Side view shown in Fig. 4. In the side wall 14 of the folder is a Knife shaft pair 16 and 18 rotatably supported, and a recess 17 is provided in which a processing element 32 is used, the one side wall 34, and a Knife shaft pair 36, 38 has. In addition, in the processing station 32 Delivery roller 40 is provided, which is used to run out of the folder Execute sheets of paper. The side wall 34 of the processing element 32 is shaped that they are inserted into the recess 17 of the side wall of the folder and locked there can be. For this purpose, it can have, in particular, a projection which extends into the Recess 17 engages. With a processing element 32 configured in this way the variability of the folding unit increases significantly since the downstream one Knife shaft pair 36 and 38 can accommodate additional machining elements with which additional grooves, crevices or perforations can be introduced. About that In addition, in this constellation there is the advantage that the processing element 32 can also be retrofitted to the folding unit as required. To the distance between the knife shafts of the second downstream pair of knife shafts 36, 38 To be able to adjust, an additional can be installed later Roll gap adjustment device (not shown) can be provided.

Eine weitere Ausgestaltung des erfindungsgemäßen Falzwerkes ist in Seitenansicht in Fig. 5 gezeigt. Eine Seitenwand 14 des Falzwerkes weist eine Ausnehmung 17 auf, in welcher ein Bearbeitungselement 42 eingebracht ist, dessen Seitenwand 44 so geformt ist, daß sie in die Ausnehmung 17 eingeführt und dort arretiert werden kann. Das Bearbeitungselement 42 weist zwei nachgelagerte Messerwellen 36 und 38 auf, die, wie in den vorhergehenden Beispielen bereits beschrieben, die Variabilität des Falzwerkes deutlich steigern. In der Seitenwand des Bearbeitungselementes 42 ist weiterhin eine Ausnehmung 46 vorgesehen, in welche wiederum ein weiteres Bearbeitungselement 20, bevorzugt schwenkbar eingebracht werden kann. Ein solches modular aufgebautes erfindungsgemäßes Falzwerk kann den jeweiligen Bedürfnissen optimal angepaßt werden, da es im Prinzip möglich ist, eine beliebige Anzahl von Bearbeitungsstationen 42 nacheinander vorzusehen, von denen jede ein nachgelagertes Messerwellenpaar 36, 38 trägt. Am Ausgang des Falzwerkes wird bevorzugt in die Ausnehmung 46 des letzten Bearbeitungselementes 42 ein um die Schwenkachse 28 drehbar gelagertes Bearbeitungselement 20 eingebracht, welches eine Ausführwalze 26 aufweist.A further embodiment of the folding unit according to the invention is shown in side view in Fig. 5 shown. A side wall 14 of the folding mechanism has a recess 17 in which incorporates a processing element 42 whose side wall 44 is shaped in such a way that it can be inserted into the recess 17 and locked there. The Processing element 42 has two downstream knife shafts 36 and 38 which, as in FIG The variability of the folding unit already described in the previous examples increase significantly. In the side wall of the processing element 42 there is still one Recess 46 is provided, in which in turn a further processing element 20, can preferably be introduced pivotably. Such a modular structure folder according to the invention can be optimally adapted to the respective needs, since in principle it is possible to have any number of processing stations 42 to be provided in succession, each of which is a downstream pair of knife shafts 36, 38 wearing. At the exit of the folder is preferably in the recess 46 of the last Processing element 42 a rotatably mounted about the pivot axis 28 Machining element 20 introduced, which has an execution roller 26.

Zur Optimierung des Antriebes eines Falzwerks ist es bereits bekannt, wie in Fig. 6 gezeigt, eine Getriebeplatte 48 vorzusehen. Hierzu wird der Schaft 21 der Falzwalze 19 über eine Kupplung 50 mit einer Antriebswelle 51 verbunden, die ihrerseits über eine Lagerung ortsfest mit einer Getriebeplatte 48 verbunden ist. Durch eine Getriebeplatte 48 hindurchgeführt. Über das außen anliegende Zahnrad 52 kann die Falzwalze 19 angetrieben werden.To optimize the drive of a folding unit, it is already known, as in FIG. 6 shown to provide a gear plate 48. For this purpose, the shaft 21 of the folding roller 19 connected via a clutch 50 to a drive shaft 51, which in turn via a Storage is fixedly connected to a gear plate 48. Through a gear plate 48 passed through. The folding roller 19 can be driven via the external gear 52 become.

Wie in Fig. 7 gezeigt, sind auf der Getriebeplatte 48 eine Vielzahl von Bohrungen vorgesehen, durch die die Falzwalzen 52a - 52j über ineinandergreifende Zahnräder angetrieben werden können. Da jede der Falzwalzen 52a - 52j über eine Kupplung, beispielsweise eine Kreuzscheibenkupplung, mit der Getriebeplatte 48 verbunden ist, ist es möglich, über die Kupplungen die veränderlichen Achs-Einstellabstände zwischen den Falzwalzen und Messerwellen zu kompensieren. In Hinblick auf den Antrieb ist das Messerwellenpaar 54 an denselben Antrieb 56 gekoppelt wie die Falzwalzen 52a - 52j, die üblicherweise über einen Zahnräderzug verbunden sind. Erfindungsgemäß wird die Getriebeplatte 48 nun so ausgeführt, dass die in den Seitenwänden modular und/oder schwenkbar vorgesehenen Messerwellen 16 und 18 sowie die schwenkbar angeordnete Ausführwalze 26 außerhalb der Getriebeplatte 48 angeordnet sind. Der Antrieb für die außerhalb der Getriebeplatte liegenden Wellen und Walzen kann mit einem Bänder-, Ketten- oder Zahnriemenantrieb erfolgen, der ein Kopplungselement 60, insbesondere ein Kopplungszahnrad beispielsweise in Richtung des angegebenen Pfades direkt antreibt. Das Kopplungszahnrad 60 steht dabei unmittelbar in Wirkverbindung mit einem Antriebszahnrad für die Messerwelle 18, das seinerseits wiederum die übrigen Zahnräder der Walzen und Wellen des Moduls antreiben kann. Damit ist gewährleistet, dass die Messerwellen 54, 16 und 18 synchron zueinander angetrieben werden. Außerdem wird durch diese Konstruktion ermöglicht, dass die Vorteile der Verwendung einer Getriebeplatte, auch bei der erfindungsgemäßen modularen Bauweise Verwendung finden können. Den synchronen bzw. aufeinander abgestimmten Antrieb der Walzen im Grundteil des Falzwerkes und der Walzen im Modul- bzw. Schwenkteil des Falzwerkes kann man allerdings auch dadurch erzielen, dass jeweils eigene Antriebe vorgesehen werden, die über eine Steuereinheit miteinander gekoppelt bzw. aufeinander abgestimmt werden. So kann beispielsweise für den Antrieb des Messerwellenpaares 54 und der Falzwalzen 52a-52j ein eigener Antrieb verwendet werden, während die Messerwellen 16, 18 und die schwenkbare Ausführwalze 26 zusammen oder jede für sich von einem eigenen Antrieb angetrieben wird, der dann bevorzugt als steuerbarer Servomotor ausgeführt ist. Die Abstimmung des Gesamtantriebs kann dann über eine eigene Antriebssteuerung erfolgen, die auch in die Gesamtmaschinensteuerung integriert sein kann.As shown in FIG. 7, a plurality of bores are provided on the gear plate 48, through which the folding rollers 52a-52j can be driven via intermeshing gear wheels. Since each of the folding rollers 52a-52j is connected to the gear plate 48 via a coupling, for example a cross-plate coupling, it is possible to compensate for the variable axis setting distances between the folding rollers and knife shafts. With regard to the drive, the pair of cutter shafts 54 is coupled to the same drive 56 as the folding rollers 52a-52j, which are usually connected via a gear train. According to the invention, the gear plate 48 is now designed such that the knife shafts 16 and 18, which are provided modularly and / or pivotably in the side walls, and the pivoting delivery roller 26 are arranged outside the gear plate 48. The drive for the shafts and rollers lying outside the gear plate can be carried out with a belt, chain or toothed belt drive, which drives a coupling element 60, in particular a coupling gearwheel, for example in the direction of the specified path. The coupling gear 60 is directly operatively connected to a drive gear for the cutter shaft 18, which in turn can drive the other gears of the rollers and shafts of the module. This ensures that the cutter shafts 54, 16 and 18 are driven synchronously with one another. It also made possible by this design is that the benefits of using a gear plate can also be used in the inventive modular design. The synchronous or coordinated drive of the rollers in the base part of the folding unit and the rollers in the module or swivel part of the folding unit can, however, also be achieved by providing separate drives which are coupled with one another or coordinated with one another via a control unit. For example, a separate drive can be used to drive the pair of cutter shafts 54 and the folding rollers 52a-52j, while the cutter shafts 16, 18 and the pivotable feed roller 26 are driven together or each by its own drive, which is then preferably a controllable servo motor is executed. The overall drive can then be tuned via its own drive control, which can also be integrated into the overall machine control.

Das erfindungsgemäße Falzwerk kann in einer oder mehrere Kombinationen der in den Beispielen der in den Figuren 1 - 7 dargestellten Ausführungsmöglichkeiten in einer Falzmaschine vorgesehen werden, sodass die Variabilität der Falzmaschine erheblich gesteigert, sowie die Zugänglichkeit zu den Messerwellen bzw. nachgelagerten Messerwellenpaaren erheblich vereinfacht wird. Damit vereinfacht sich auch die Einstellbarkeit des Messerwellenpaares erheblich.The folder according to the invention can be in one or more combinations of those in the Examples of the possible embodiments shown in FIGS. 1-7 in a Folding machine are provided so that the variability of the folding machine is considerable increased, as well as accessibility to the knife shafts or downstream Knife shaft pairs is considerably simplified. This also simplifies the Adjustability of the pair of knife shafts considerably.

Die einzelnen Walzen werden üblicherweise durch Zahnräder angetrieben, wobei die Enden der Walzen selbst als Zahnräder ausgeführt sein können, die entweder ineinander greifen oder über Zwischenzahnräder verbunden sind. Das Ein- und Auskoppeln der Antriebe der Walzen erfolgt somit üblicherweise durch das Ausheben des Zahnrades aus dem Eingriff. The individual rollers are usually driven by gears, the Ends of the rollers themselves can be designed as gear wheels, which either interlock grab or are connected via intermediate gears. The coupling and decoupling of the The rollers are thus usually driven by lifting the gear wheel the intervention.
