Description

Die Erfindung betrifft ein Schwertfalzwerk mit einer einem Falzschwert und einem Paar Falzwalzen zugeordneten Transporteinrichtung, durch welche eine Signatur vor dem Falzvorgang an einen Vorderkantenanschlag befördert wird.The invention relates to a sword folder with a folding blade and a pair of folding rollers associated transport device through which a signature is conveyed before the folding to a leading edge stop.

Um eine möglichst präzise Falzung einer durch eine Transporteinrichtung an ein Schwertfalzwerk herantransportierte Signatur zu ermöglichen, sind typischerweise Vorderkantenanschläge und oft Seitenkantenanschläge vorgesehen, sodass die Signatur während des Verzögerungs- oder Bremsvorgangs eine Führung erfährt und ausgerichtet entlang der durch die Geometrie des Falzschwertes vorgegebenen Koordinaten wird. Bekannte Ausführungen von Schwertfalzwerken weisen typischerweise motorisch verstellbare Anschlagträger mit fest fixierten Anschlagfingern, häufig vorgesehen für ein minimales Format der zu verarbeitenden Signaturen, auf. Schwertfalzwerke in Falzmaschinen werden insbesondere zur Erzeugung von Kreuzbrüchen verwerdet, beispielsweise in sogenannten Kombifalzmaschinen, welche sowohl wenigstens ein Taschen- als auch ein Schwertfalzwerk aufweisen.In order to enable the most accurate possible folding of a transported by a transport device to a sword folder signature, front edge stops and often side edge stops are typically provided so that the signature undergoes guidance during the deceleration or braking operation and aligned along the predetermined by the geometry of the folding blade coordinates. Known designs of Schwertfalzwerken typically have motorized stop carrier with fixed fixed stop fingers, often provided for a minimum format of the processed signatures on. Schwertfalzwerke in folding machines are verwerdet particular for the production of cross cracks, for example in so-called Kombifalzmaschinen, which have both at least one pocket and a sword folder.

Beispielsweise sind in der US 5,158,524 derartige Anschläge an einem Schwertfalzwerk offenbart. In diesem Dokument ist ein Schwertfalzwerk mit einem Vorderkantenanschlag zur Abbremsung der Bewegung eines mit einer Transporteinrichtung über den Falzspalt beförderten Bogens und mit Anschlägen zur Vermeidung einer Vertikalbewegung der Seitenkanten des Bogens während des Falzvorgangs dargestellt. Die Anschläge zur Vermeidung einer Vertikalbewegung und der Vorderkantenanschlag sind bewegbar und können zusammen bewegt werden, beispielsweise um sie vom Falzspalt im Fall einer Fehloperation zur schnellen Behebung des Problems abzuziehen.For example, US 5,158,524 discloses such stops on a knife folder. This document discloses a blade folder having a leading edge stop for slowing the movement of a sheet conveyed across the seam gap by a conveyor and stops for preventing vertical movement of the side edges of the sheet during the folding operation. The vertical motion stops and the leading edge stop are movable and can be moved together, for example, to pull them off the folding nip in the event of a misoperation to quickly fix the problem.

Insbesondere bei großen Formaten der zu falzenden Signaturen und dünnem Bedruckstoff kann es bei fest vorgesehenen und beabstandeten Anschlagfingern zu Markierungsbildung kommen. Zudem wird keine sichere Anschlagkante für die Vorderkante der Signatur gebildet, sodass bei einer heftigen Abbremsung der Signatur diese schräg über dem Falzspalt zu liegen kommen kann. Durch diese derartige Verdrehung der Signatur können Falzungenauigkeiten entstehen.Particularly in the case of large formats of the signatures to be folded and of the thin printing substrate, it is possible to form marks in the case of firmly provided and spaced stop fingers come. In addition, no secure stop edge is formed for the leading edge of the signature, so that at a sharp deceleration of the signature this can come to lie obliquely above the folding gap. By such rotation of the signature folding inaccuracies may arise.

Um eine oben angesprochene Markierungsbildung zu vermeiden und um eine sichere Arbeitsweise bei allen Formaten zu gewährleisten, werden häufig nach dem Einstellen der Seitenanschläge zusätzliche Anschlagfinger manuell, dem Format der zu falzenden Signatur entsprechend, eingebaut. Diese zusätzlichen Anschlagfinger müssen wieder ausgebaut werden, sobald die Seitenanschläge bewegt werden sollen. Eine automatische Formateinstellung ist auf diesem Wege nicht möglich.To avoid the above-mentioned marking formation and to ensure safe operation in all formats, additional stop fingers are often manually after the setting of the side stops, the format of the signature to be folded, installed. These additional stop fingers must be removed again as soon as the side stops are to be moved. An automatic format setting is not possible in this way.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Schwertfalzwerk mit einstellbaren Anschlägen zu schaffen, welches eine Anschlagkonfiguration in Abhängigkeit von Material- und Produktionsparametern ermöglicht. Insbesondere liegt der Erfindung die Aufgabe zu Grunde, dass eine automatische Einstellung vorgenommen werden kann.The invention is therefore based on the object to provide a sword folder with adjustable stops, which allows a stop configuration depending on material and production parameters. In particular, the invention is based on the object that an automatic adjustment can be made.

Diese Aufgabe wird durch ein Schwertfalzwerk mit den Merkmalen gemäß Anspruch 1 gelöst. Vorteilhafte Ausführungsformen und Weiterbildungen des erfindungsgemäßen Schwertfalzwerkes sind in den Unteransprüchen charakterisiert.This object is achieved by a sword folder with the features of claim 1. Advantageous embodiments and developments of the invention Schwertfalzwerkes are characterized in the subclaims.

Das erfindungsgemäße Schwertfalzwerk umfasst eine einem Falzschwert und einem Paar Falzwalzen zugeordnete Transporteinrichtung, durch welche eine Signatur vor dem Falzvorgang an einen Vorderkantenanschlag befördert wird. Es zeichnet sich dadurch aus, dass der Vorderkantenanschlag wenigstens einen relativ zum Falzschwert bewegbaren Anschlagträger umfasst, welcher wenigstens einen relativ zum Anschlagträger bewegbaren Anschlagfinger mit Führungsstäben aufweist.The sword folding mechanism according to the invention comprises a transport device associated with a folding blade and a pair of folding rollers, by means of which a signature is conveyed to a front edge stop before the folding operation. It is characterized in that the leading edge stop comprises at least one stop carrier which can be moved relative to the folding blade and which has at least one stop finger with guide bars movable relative to the stop carrier.

Die Konstruktion des erfindungsgemäßen Schwertfalzwerkes ist derart ausgelegt, dass der Anschlagträger und die Anschlagfinger entsprechend dem Format der zu falzenden Signatur vollautomatisch eingestellt werden können. Die Anschlagfinger sind dabei im Wesentlichen senkrecht zu der durch die Transporteinrichtung definierten Fläche bewegbar, während die Führungsstäbe im Wesentlichen parallel zur durch die Transporteinrichtung definierten Fläche liegen.The construction of the Schwertfalzwerkes invention is designed so that the stop carrier and the stop fingers can be set fully automatically according to the format of the signature to be folded. The stop fingers are in the Move substantially perpendicular to the surface defined by the transport device, while the guide rods are substantially parallel to the surface defined by the transport device.

Zusätzlich können mit besonderem Vorteil Seitenanschläge zur Ausrichtung der Signatur entlang durch die Geometrie des Falzschwertes vorgegebenen Koordinaten vorgesehen sein. Wenigstens einer der Seitenanschläge des erfindungsgemäßen Schwertfalzwerkes weist wenigstens ein Niederhalteband oberhalb und/oder ein Transportband unterhalb des Transportweges der Signatur auf. Wenigstens einer der Seitenanschläge ist relativ zum Falzschwert bewegbar, typischerweise im Wesentlichen senkrecht zur Transportrichtung der zu falzenden Signatur. Wenigstens zwischen einem Seitenanschlag und einer Führungsschiene an einem Leitblech unterhalb des Falzschwertes oberhalb und/oder unterhalb des Transportweges der Signatur sind Scherengitter vorgesehen.In addition, it is particularly advantageous to provide side stops for aligning the signature along coordinates given by the geometry of the folding blade. At least one of the side stops of the Schwertfalzwerkes invention has at least one hold-down above and / or a conveyor belt below the transport path of the signature. At least one of the side stops is movable relative to the folding blade, typically substantially perpendicular to the transport direction of the signature to be folded. At least between a side stop and a guide rail on a guide plate below the folding blade above and / or below the transport path of the signature scissor lattice are provided.

Für wenigstens einen Anschlagfinger ist eine Ruheposition und wenigstens eine aktive Position vorgesehen. In der Ruheposition gibt der Anschlagfinger den Transportweg der Signatur am Falzschwert vorbei frei, während in der aktiven Position der Anschlagfinger den Transportweg der Signatur über die Position des Falzschwertes hinaus blockiert. Wenigstens ein Abschnitt der unteren Führungsstäbe unterhalb der durch die Transportrichtung definierten Ebene und ein Abschnitt der oberen Führungsstäbe oberhalb der durch die Transportrichtung definierten Ebene verhindern eine Bewegung der Signatur aus der durch die Transportrichtung definierten Ebene heraus. Wenn mehrere Anschlagfinger vorgesehen sind, können wenigstens zwei Anschlagfinger unabhängig voneinander von der Ruheposition in eine aktive Position und zurück gebracht werden. Die Bewegung des Anschlagträgers und/oder die Bewegung wenigstens eines Anschlagfingers und/oder eines Seitenanschlags erfolgt mit besonderem Vorteil mittels wenigstens eines Aktuators. Beispielsweise kann ein geeigneter Aktuator ein ventilgesteuerter Pneumatikzylinder oder ein Servomotor sein.For at least one stop finger, a rest position and at least one active position is provided. In the rest position, the stop finger releases the transport path of the signature past the folding blade, while in the active position the stop finger blocks the transport path of the signature beyond the position of the folding blade. At least a portion of the lower guide bars below the plane defined by the transport direction and a portion of the upper guide bars above the plane defined by the transport direction prevent movement of the signature out of the plane defined by the transport direction. If a plurality of stop fingers are provided, at least two stop fingers can be independently brought from the rest position to an active position and back. The movement of the stop carrier and / or the movement of at least one stop finger and / or a side stop is carried out with particular advantage by means of at least one actuator. For example, a suitable actuator may be a valve-controlled pneumatic cylinder or a servomotor.

Besonders vorteilhaft ist zusätzlich eine Steuerungseinheit für das Schwertfalzwerk vorgesehen. Die Steuerungseinheit steuert dabei wenigstens einen Aktuator in Funktion wenigstens eines Material- oder Produktionsparameters, also eines Signaturparameters, beispielsweise des Formates, derart an, dass eine dem Format der zu falzenden Signatur entsprechende Positionierung des Anschlagträgers und/oder wenigstens eines Anschlagfingers und/oder wenigstens eines Seitenanschlages erfolgt. Durch diese Maßnahmen ist es möglich, die Markierungen an der Vorderkante der zu falzenden Signatur zu verringern. Eine automatische Einstellung der Anschläge in Abhängigkeit von Material- oder Produktionsparametern, insbesondere in Abhängigkeit des Formates der Signatur, ist ermöglicht. Durch die relativ zum Anschlagträger bewegbaren Anschlagfinger mit Führungsstäben ist es darüber hinaus möglich, eine Bewegung der Seitenkantenanschläge durchzuführen, ohne dass eine manuelle Veränderung des Vorderkantenanschlages erforderlich ist.Particularly advantageous, a control unit for the sword folder is additionally provided. The control unit controls at least one actuator in function at least one material or production parameter, ie a signature parameter, for example of the format, such that a positioning of the stop carrier and / or at least one stop finger and / or at least one side stop takes place corresponding to the format of the signature to be folded. By these measures, it is possible to reduce the markings on the leading edge of the signature to be folded. An automatic adjustment of the attacks depending on material or production parameters, in particular depending on the format of the signature, is possible. In addition, by the stop fingers with guide rods movable relative to the stop carrier, it is possible to perform a movement of the side edge stops, without requiring a manual change of the leading edge stop.

Mit besonderem Vorteil wird das erfindungsgemäße Schwertfalzwerk in einer Falzmaschine für bogenförmiges Material mit wenigstens einem Anleger, einer Transporteinrichtung, wenigstens einem Falzwerk und einer Auslage eingesetzt. Insbesondere kann die Falzmaschine dabei zusätzlich wenigstens ein Taschenfalzwerk aufweisen, also eine sogenannte Kombifalzmaschine sein.With particular advantage, the sword folder according to the invention is used in a folding machine for sheet material with at least one feeder, a transport device, at least one folding unit and a delivery. In particular, the folding machine can additionally comprise at least one pocket folder, ie a so-called combination folding machine.

Entlang der durch einen Pfeil gekennzeichneten Transportrichtung 30 gelangen Signaturen 23, wie in der Figur 1a gezeigt, in das erfindungsgemäße Schwertfalzwerk unter ein Falzschwert 22. Die zugeordneten Falzwalzen 24 sind in dieser Darstellung durch einen Teil der Transporteinrichtung verdeckt. Es ist ein Transportband 7, welches eine Bandwalze 4 und eine auf einer Vierkanttraverse 5 aufgenommene Rolle umschließt, zu sehen. Oberhalb der durch die Signatur 23 definierten Ebene ist ein Vorderkantenanschlag 2 in der Ruheposition gezeigt. Der Vorderkantenanschlag 2 weist dabei einen Anschlagträger 16 mit einem ausfahrbaren Anschlagfinger 17 auf. Der Anschlagträger 16 kann vermittels einer an einer Traverse 3 aufgenommenen Einstelleinheit 15 entlang der Transportrichtung der Signatur 23 bewegt werden. Der Vorderanschlag 2 umfasst dabei eine Führungsstabeinheit 19, welche zur Aufnehmung eines oberen Führungsstabes 19.1 und eines unteren Führungsstabes 19.2 einen ausfahrbaren Führungsstabhalter 19.3, welcher im wesentlichen senkrecht zur durch die Transportrichtung der Signatur 23 definierten Ebene bewegbar ist, aufweist. Der obere Führungsstab 19.1 und der untere Führungsstab 19.2 sind dabei derart beabstandet, dass eine Signatur 23 in den durch die Führungsstäbe 19.1 und 19.2 gebildeten Spalt eingeführt werden kann. Der obere Führungsstab 19.1 und der untere Führungsstab 19.2 passieren den Anschlagfinger 17, beispielhaft durch jeweils eine zugeordnete Ausnehmung. In anderen Worten: Die beabstandeten Führungsstäbe 19.1 und 19.2 weisen Lagerungspunkte im Führungsstabhalter 19.3 und im Anschlagfinger 17 auf, welche beide im Wesentlichen senkrecht zur durch die Transportrichtung der Signatur 23 definierten Ebene bewegbar sind. Des Weiteren ist oberhalb der durch die Transportrichtung der Signatur 23 definierten Ebene ein Scherengitter 21 und unterhalb der Ebene ein Scherengitter 13 und ein Scherengitter 20 zur Führung der Signatur vorgesehen.1 shows a schematic view of an advantageous embodiment of the invention Schwertfalzwerkes with front stops in the rest position. Along the direction of transport 30 indicated by an arrow, signatures 23, as shown in FIG. 1 a, enter the knife-folding mechanism according to the invention under a folding blade 22. The associated folding rollers 24 are concealed in this illustration by a part of the transporting device. It is a conveyor belt 7, which encloses a belt roller 4 and a roller accommodated on a square cross member 5, can be seen. Above the plane defined by the signature 23, a leading edge stop 2 is shown in the rest position. The leading edge stop 2 in this case has a stop carrier 16 with an extendable stop finger 17. The stop carrier 16 can be moved by means of an adjustment unit 15 received on a cross member 3 along the transport direction of the signature 23. The front stop 2 in this case comprises a guide rod unit 19, which for the Aufnehmung an upper guide rod 19.1 and a lower guide rod 19.2 an extendable guide rod holder 19.3, which is substantially perpendicular to the plane defined by the transport direction of the signature 23 movable. The upper guide rod 19.1 and the lower guide rod 19.2 are spaced apart such that a signature 23 can be introduced into the gap formed by the guide rods 19.1 and 19.2. The upper guide rod 19.1 and the lower guide rod 19.2 pass the stop finger 17, by way of example one associated recess. In other words, the spaced guide rods 19.1 and 19.2 have storage points in the guide rod holder 19.3 and in the stop finger 17, which are both substantially perpendicular to the plane defined by the transport direction of the signature 23 movable. Furthermore, above the plane defined by the transport direction of the signature 23 a scissors grating 21 and below the plane a scissors grille 13 and a scissor grille 20 for guiding the signature is provided.

In der Figur 1b ist im Detail der Anschlagträger 16 mit dem Anschlagfinger 17 gezeigt. Der Anschlagfinger 17 ist relativ zum Anschlagträger 16 entlang der Ausfahrrichtung 31 bewegbar. Er umfasst den Anschlag 17.1, durch welchen der obere Führungsstab 19.1 und der untere Führungsstab 19.2 passieren, einen Pneumatikzylinder 17.2 nebst einem Steuerungsventil 17.3 und Führungen 17.4 durch den Anschlagträger 16.FIG. 1 b shows in detail the stop carrier 16 with the stop finger 17. The stop finger 17 is movable relative to the stop carrier 16 along the extension direction 31. It comprises the stop 17.1, through which the upper guide rod 19.1 and the lower guide rod 19.2 pass, a pneumatic cylinder 17.2 together with a control valve 17.3 and guides 17.4 through the stop carrier 16.

Die Figur 2 zeigt schematisch eine Ansicht der vorteilhaften Ausführungsform des erfindungsgemäßen Schwertfalzwerkes mit Vorderanschlägen in einer aktiven Position. In der Figur 2a ist gezeigt, wie in einer aktiven Position des Anschlagfingers und des Führungsstabhalters 19.3 der obere Führungsstab 19.1 oberhalb der durch die Signatur 23 definierten Ebene und der untere Führungsstab 19.2 unterhalb der durch die Transportrichtung der Signatur 23 definierten Ebene zu liegen kommt. Die Signatur 23 wird in dieser aktiven Position durch den Anschlagfinger 17 des Vorderkantenanschlag 2 abgebremst und liegt vor dem eigentlichen Falzvorgang unterhalb des Falzschwertes 22. Die Position des Anschlagträgers 16, also der Abstand des Anschlagträgers 16 zum Falzschwert 22, bestimmt die Lage der Signatur 23 zum Falzschwert 22 und wird in Funktion des Formates der zu falzenden Signatur 23 eingestellt.2 shows schematically a view of the advantageous embodiment of the invention Schwertfalzwerkes with front stops in an active position. FIG. 2a shows how, in an active position of the stop finger and the guide rod holder 19.3, the upper guide rod 19.1 comes to rest below the plane defined by the signature 23 and the lower guide rod 19.2 below the plane defined by the transport direction of the signature 23. The signature 23 is decelerated in this active position by the stop finger 17 of the leading edge stop 2 and is before the actual folding below the folding blade 22. The position of the stop carrier 16, so the distance of the stop carrier 16 to the folding blade 22, determines the position of the signature 23 for Falzschwert 22 and is set in function of the format of the signature 23 to be folded.

In der Figur 2b ist im Detail der Anschlagträger 16 mit einem ausgefahrenen Anschlagfinger 17 gezeigt. Der Anschlagfinger 17 ist entlang der Ausfahrrichtung 31 relativ zum Anschlagträger 16 bewegbar. Er umfasst dabei den Anschlag 17.1, einen Pneumatikzylinder 17.2 nebst Steuerungsventil 17.3 und Führungen 17.4 durch den Anschlagträger 16. Der Anschlag 17.1 nimmt einen oberen Führungsstab 19.1 und einen unteren Führungsstab 19.2 auf.FIG. 2 b shows in detail the stop carrier 16 with an extended stop finger 17. The stop finger 17 is movable along the extension direction 31 relative to the stop carrier 16. It includes the stop 17.1, a pneumatic cylinder 17.2 together with the control valve 17.3 and guides 17.4 through the stop carrier 16. The stop 17.1 receives an upper guide rod 19.1 and a lower guide rod 19.2.

Dem Anschlagträger 16 mit Anschlagfinger 17 entsprechend, aber nicht zeichnerisch dargestellt, ist eine Führungsstabeinheit 19 derart aufgebaut, dass sie einen Führungsstabhalter 19.3, einen Pneumatikzylinder 19.4 mit Steuerungsventil 19.5 und Führungen 19.6 durch den Führungsstabträger 18 hindurch aufweist.The stop carrier 16 with stop finger 17 according to, but not shown in the drawing, a guide rod unit 19 is constructed such that it has a guide rod holder 19.3, a pneumatic cylinder 19.4 with control valve 19.5 and guides 19.6 through the guide rod carrier 18 therethrough.

In der Figur 3 ist eine schematische Draufsicht einer vorteilhaften Ausführungsform des erfindungsgemäßen Schwertfalzwerkes mit Vorderkantenanschlägen, Seitenanschlägen und Scherengittern gezeigt. Entlang der Transportrichtung 30 gelangt eine Signatur 23 mit Hilfe von Transportbändern 7 und 9.2 unter das Falzschwert 22. Der Antrieb der Transportbänder 7 und 9.2 erfolgt durch eine rotierende Bandwalze 4. Durch die Einstellung des Vorderkantenanschlags 2, eines linken Seitenkantenanschlags 9 und eines rechten Seitenkantenanschlags 10 wird relativ zum Falzschwert 22 eine präzise Positionierung der Signatur 23 vor dem eigentlichen Falzvorgang durch das Falzschwert 22 erreicht. Die Seitenteile 1, die Traverse 3 mit der Vierkanttraverse 5 und die Bandwalze 4 bilden dabei eine Art Rahmen, zu welchem der Vorderkantenanschlag 2, der linke Seitenkantenanschlag 9 und der rechte Seitenkantenanschlag 10 relativ bewegt werden. Etwa mittig zu diesem Rahmen ist ein Leitblech 6 mit Führungsschienen 8 vorgesehen. Die Transportbänder 7 und die Führungsschienen 8 bleiben bei einer Formatverstellung des Vorderkantenanschlags 2 und/oder der Seitenkantenanschläge 9 und 10 in ihrer Position unverändert. Der linke Seitenkantenanschlag 9 weist dabei bevorzugt eine Bandspannrolle 9.1, das Transportband 9.2, eine Andrückrolle 9.3, Spindelmuttern 9.4 und den eigentlichen Seitenanschlag 9.5 auf. Entsprechendes gilt für den rechten Seitenkantenanschlag 10. Der komplette linke Seitenkantenanschlag 9 ist mit Hilfe einer ersten Einstelleinheit 11.1 und einer zweiten Einstelleinheit 11.2, hier beispielhaft gezeigt mittels eines Spindelantriebs, bewegbar. Eine Einstelleinheit 11.1 bzw. 11.2 weist dabei bevorzugt einen Spindelantrieb mit Motor, Getriebe und Drehgeber auf. Beispielhaft ist in der Figur 3 ein Vorderkantenanschlag 2 mit einem Anschlagträger 16 mit beispielhaft sechs ausfahrbaren Anschlagfingern 17, wie sie bereits in den Figuren 1 und 2 beschrieben worden sind, gezeigt. Des Weiteren umfasst der Vorderkantenanschlag 2 einen Führungsstabträger 18, welcher beispielhaft sechs Führungsstabeinheiten 19 aufweist. Die Draufsicht zeigt daher sechs obere Führungsstäbe 19.1. Der Anschlagträger 16 ist beispielhaft mittels eines Spindelantriebs durch eine linke Einstelleinheit 14 und eine rechte Einstelleinheit 15 im Wesentlichen parallel zu der durch die Transportrichtung 30 definierten Richtung bewegbar. Der komplette rechte Seitenkantenanschlag 10 wird mit Hilfe einer ersten Einstelleinheit 12.1 und einer zweiten Einstelleinheit 12.2 bewegt. Beispielhaft sind hier zwei linke Einstelleinheiten 11.1 und 11.2 und zwei rechte Einstelleinheiten 12.1 und 12.2 gezeigt, im allgemeinen kann aber auch eine Konfiguration mit einer einzelnen Einstelleinheit oder mehreren Einstelleinheiten vorgesehen sein.In the figure 3 is a schematic plan view of an advantageous embodiment of the invention Schwertfalzwerkes with leading edge stops, side stops and scissors lattice shown. The drive of the conveyor belts 7 and 9.2 is effected by a rotating belt roller 4. By setting the leading edge stopper 2, a left side edge stopper 9 and a right side edge stopper 10th is achieved relative to the folding blade 22, a precise positioning of the signature 23 before the actual folding process by the folding blade 22. The side parts 1, the cross member 3 with the square cross member 5 and the band roller 4 thereby form a kind of frame to which the leading edge stopper 2, the left side edge stopper 9 and the right side edge stopper 10 are relatively moved. Approximately in the middle of this frame, a guide plate 6 is provided with guide rails 8. The conveyor belts 7 and the guide rails 8 remain unchanged at a format adjustment of the leading edge stop 2 and / or the side edge stops 9 and 10 in their position. The left side edge stop 9 in this case preferably has a belt tension pulley 9.1, the conveyor belt 9.2, a pressure roller 9.3, spindle nuts 9.4 and the actual side stop 9.5. The same applies to the right side edge stop 10. The complete left side edge stop 9 is movable by means of a first setting unit 11.1 and a second setting unit 11.2, shown here by way of example by means of a spindle drive. An adjusting unit 11.1 or 11.2 preferably has a spindle drive with motor, gear and rotary encoder. By way of example, FIG. 3 shows a front edge stop 2 with a stop carrier 16 with, by way of example, six extendable stop fingers 17, as already described in FIGS. 1 and 2. Furthermore, the leading edge stop 2 comprises a guide rod carrier 18, which by way of example has six guide rod units 19. The plan view therefore shows six upper guide rods 19.1. The stop carrier 16 is movable by way of example by means of a spindle drive by a left adjustment unit 14 and a right adjustment unit 15 substantially parallel to the direction defined by the transport direction 30. The complete right side edge stop 10 is moved by means of a first setting unit 12.1 and a second setting unit 12.2. By way of example, two left adjusting units 11.1 and 11.2 and two right adjusting units 12.1 and 12.2 are shown here, but in general a configuration with a single setting unit or a plurality of setting units may also be provided.

Zur Führung oder Stabilisierung der Signatur entlang der Transportebene sind oberhalb der durch die Transportrichtung 30 definierten Ebene und/oder unterhalb der durch die Transportrichtung 30 definierten Ebene Scherengitter vorgesehen. Beispielhaft ist in der Figur 3 ein oberes Scherengitter 21 aufgespannt zwischen einer Führungsschiene 8 und dem rechten Seitenkantenanschlag 10 gezeigt. Ein unteres Scherengitter 20 ist am Leitblech 6 und am Seitenanschlag 9.5 des linken Seitenkantenanschlags 9 gezeigt.To guide or stabilize the signature along the transport plane, scissors grids are provided above the plane defined by the transport direction 30 and / or below the plane defined by the transport direction 30. By way of example, in FIG. 3, an upper scissor lattice 21 is shown spanned between a guide rail 8 and the right-hand side edge stop 10. A lower scissor lattice 20 is shown on the baffle 6 and on the side stop 9.5 of the left side edge stop 9.

Mit anderen Worten: Die zu falzende Signatur erfährt von unten eine Unterstützung von den unteren Scherengittern 20 und den Führungsstäben 19.2 des Vorderkantenanschlags 2. Mit Hilfe der oberen Scherengitter 21 und der oberen Führungsstäbe 19.1 wird die zu falzende Signatur niedergehalten.In other words, the signature to be folded learns from below a support from the lower scissors lattices 20 and the guide rods 19.2 of the leading edge stop 2. With the help of the upper scissor lattice 21 and the upper guide rods 19.1 the signature to be folded is held down.

Für Signaturen, welche, ohne gefalzt zu werden, über die Position des Schwertfalzwerkes hinaus auf eine hier nicht gezeigte Auslage befördert werden, müssen die ausfahrbaren Anschlagfinger 17, wie in Figur 1 gezeigt, sich in der Ruheposition befinden. Zur Unterstützung der Signatur von unten sind weitere untere Scherengitter 13 vorgesehen. In der Figur 3 sind diese unteren Scherengitter 13 zusammengefaltet gezeigt. Mit Hilfe einer linken Einstelleinheit 25 und einer rechten Einstelleinheit 26, beispielhaft vermittels eines Seilantriebs mit Motor, Getriebe und Drehgeber, können diese unteren Scherengitter 13 aus ihrer Ruhelage (zusammengefaltet) in wenigstens eine Arbeitslage (ausgefaltet) gebracht werden.For signatures which, without being folded, are conveyed beyond the position of the sword folder to a delivery not shown here, the extendable stop fingers 17, as shown in FIG. 1, must be in the rest position. To support the signature from below further lower scissor grille 13 are provided. In the figure 3, these lower scissor lattice 13 are shown folded. By means of a left adjustment unit 25 and a right adjustment unit 26, by way of example by means of a cable drive with motor, gearbox and shaft encoder, these lower scissor latches 13 can be brought from their rest position (folded) into at least one working position (unfolded).

Eine automatische Einstellung in Funktion von Signaturparametern oder Produktionsparametern kann mit dem erfindungsgemäßen Schwertfalzwerk wie folgt erreicht werden: Eine hier nicht in den Figuren gezeigte Steuerungseinheit verfügt beispielsweise nach Eingabe oder Messung über die entsprechenden Parameter. Mittels entsprechender Wirkverbindungen zu den Einstelleinheiten 11.1, 11.2, 12.1 und 12.2 kann der linke Seitenkantenanschlag 9 und der rechte Seitenkantenanschlag 10 in eine gewünschte Position, insbesondere dem Format der Signatur entsprechend, bewegt werden. Der Anschlagträger 16 des Vorderkantenanschlags 2 kann mit Hilfe der linken Einstelleinheit 14 und der rechten Einstelleinheit 15, welche in Wirkverbindung mit der Steuerungseinheit stehen, mit eingefahrenen Anschlagfingern 17 in die erforderliche Position gebracht werden. Abhängig von der Breite der zu falzenden Signatur und unabhängig voneinander können Anschlagfinger 17 mit Führungsstabeinheiten 19 gleichzeitig bewegt werden und von der Ruheposition in eine aktive Position gebracht werden.An automatic setting as a function of signature parameters or production parameters can be achieved with the sword folder according to the invention as follows: A control unit, not shown here in the figures, has the corresponding parameters after input or measurement, for example. By means of corresponding active connections to the setting units 11.1, 11.2, 12.1 and 12.2, the left side edge stop 9 and the right side edge stop 10 can be moved to a desired position, in particular the format of the signature. The stop carrier 16 of the leading edge stop 2 can be brought into the required position with retracted stop fingers 17 by means of the left adjustment unit 14 and the right adjustment unit 15, which are in operative connection with the control unit. Depending on the width of the signature to be folded and independently of each other, stop fingers 17 can be simultaneously moved with guide bar units 19 and brought from the rest position into an active position.

Die Figur 4 zeigt ein Detail der schematischen Ansicht der Seitenanschläge nebst Scherengittern des erfindungsgemäßen Schwertfalzwerkes entlang der durch die Transportrichtung definierten Ebene. Die Figur 4 zeigt beispielhaft eine spiegelsymmetrische Anordnung. Die Falzung einer Signatur 23 erfolgt durch die Bewegung des Falzschwertes 22 in der Symmetrieebene in Richtung auf die Falzwalzen 24. Zwischen Leitblech 6 und linkem Seitenkantenanschlag 9 sowie zwischen Leitblech 6 und rechtem Seitenkantenanschlag 10 ist jeweils ein unteres Scherengitter 20 aufgenommen. Der linke Seitenkantenanschlag 9 steht in Wirkverbindung mit einer zweiten Einstelleinheit 11.2, welche an einem Seitenteil 1 aufgenommen ist, und ist bewegbar. Entsprechend steht der rechte Seitenkantenanschlag 10 in Wirkverbindung mit einer zweiten Einstelleinheit 12.2, welche an einem Seitenteil 1 aufgenommen ist, und ist bewegbar. Zwischen dem linken Seitenkantenanschlag 9 und einer Führungsschiene 8 ist ein oberes Scherengitter 21 gespannt, während zwischen dem rechten Seitenkantenanschlag 10 und der Führungsschiene 8 ein oberes Scherengitter 21 aufgenommen ist.FIG. 4 shows a detail of the schematic view of the side stops together with the lattice grates of the sword folder according to the invention along the plane defined by the transport direction. FIG. 4 shows by way of example a mirror-symmetrical arrangement. The folding of a signature 23 takes place by the movement of the folding blade 22 in the plane of symmetry in the direction of the folding rollers 24. Between baffle 6 and left side edge stopper 9 and between baffle 6 and right side edge stop 10 each a lower scissors lattice 20 is added. The left side edge stop 9 is operatively connected to a second setting unit 11.2, which is received on a side part 1, and is movable. Accordingly, the right side edge stop 10 is operatively connected to a second setting unit 12. 2 received on a side part 1 and is movable. Between the left side edge stopper 9 and a guide rail 8, an upper scissor lattice 21 is tensioned, while between the right side edge stop 10 and the guide rail 8, an upper scissors lattice 21 is received.

Die Figur 5 stellt ein Detail der schematischen Ansicht der Vorderanschläge und Scherengitter des erfindungsgemäßen Schwertfalzwerks entlang der durch die Transportrichtung definierten Ebene dar. Beispielhaft ist hier wiederum eine symmetrische Ausführungsform gezeigt. In der Nähe der Symmetrieebene ist das Falzschwert 22 mit den zugehörigen Falzwalzen 24 angeordnet. Die Figur 5 zeigt den Anschlagträger 16 mit beispielhaft sechs Anschlagfingern 17, wobei zwei Anschlagfinger 17 aufgefahrene Anschläge 17.1 in einer aktiven Position aufweisen. Unterhalb der durch die Lage der Signatur 23 unterhalb des Falzschwertes 22 definierten Ebene befindet sich ein unteres Scherengitter 13 in einer Ruhelage. Auf der anderen Seite der Symmetrieebene sind Anschlagfinger 17 mit Anschlägen 17.1 in der Ruheposition gezeigt. Das zugeordnete untere Scherengitter 13 ist hier beispielhaft in einer aktiven Position gezeigt. Mittels eines Seiles 29 und einer linken Einstelleinheit 25 bzw. einer rechten Einstelleinheit 26 können die unteren Scherengitter 13 bewegt, also aus- oder eingefahren werden.FIG. 5 shows a detail of the schematic view of the front stops and the lattice grates of the sword folder according to the invention along the plane defined by the transport direction. By way of example, a symmetrical embodiment is again shown by way of example. In the vicinity of the plane of symmetry, the folding blade 22 is arranged with the associated folding rollers 24. FIG. 5 shows the stop carrier 16 with, for example, six stop fingers 17, wherein two stop fingers 17 have raised stops 17.1 in an active position. Below the plane defined by the position of the signature 23 below the folding blade 22 is a lower scissor lattice 13 in a rest position. On the other side of the plane of symmetry stop fingers 17 are shown with stops 17.1 in the rest position. The associated lower cutter lattice 13 is shown here in an active position by way of example. By means of a cable 29 and a left adjustment unit 25 and a right adjustment unit 26, the lower scissor lattice 13 can be moved, so off or retracted.
