Abstract
Description
Die Erfindung betrifft ein Schwertfalzwerk mit einer einem Falzschwert und einem Paar Falzwalzen zugeordneten Transporteinrichtung, durch welche eine Signatur vor der Falzung in einer Transportebene an eine Anschlagträgereinheit befördert werden kann.The invention relates to a sword folder with a folding blade and a pair of folding rollers associated transport means by which a signature can be conveyed to a stop carrier unit before folding in a transport plane.
Um eine möglichst präzise Falzung einer durch eine Transporteinrichtung an ein Schwertfalzwerk herantransportierte Signatur zu ermöglichen, sind typischerweise ein Vorderkantenanschlag und 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, um zwischen die Transporteinrichtung in den Transportweg der Signatur zu gelangen. Schwertfalzwerke in Falzrnaschinen werden insbesondere zur Erzeugung von Kreuzbrüchen verwendet, 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, typically a leading edge stop and side edge stops are 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 motor-adjustable stop carrier with fixed fixed stop fingers, often provided for a minimum format of the signatures to be processed, in order to get between the transport device in the transport path of the signature. Schwertfalzwerke Falzrnaschinen be used in particular for the production of cross fractures, for example in so-called combination folding machines, which have both at least one pocket and a Schwertfalzwerk.

Im Dokument
Insbesondere bei großen Formaten der zu falzenden Signaturen und dünnem Bedruckstoff kann es bei fest vorgesehenen und beabstandeten Anschlagfingern eines Vorderkantenanschlags 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 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, marking formation can occur in the case of firmly provided and spaced stop fingers of a leading edge stop. 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. This twisting of the signature can cause folding inaccuracies.
Um eine oben angesprochene Markierungsbildung zu vermeiden und um eine sichere Arbeitsweise bei allen Formaten zu gewährleisten, werden häufig bei gängigen Falzmaschinen 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 Einstellung, insbesondere zur Berücksichtigung des Formates der Signatur, ist auf diesem Wege nicht möglich.In order to avoid the above-mentioned marking formation and to ensure safe operation in all formats, additional stop fingers are often manually in the folding machines after adjusting 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 adjustment, in particular to take account of the format of the signature, is not possible in this way.
Der Erfindung liegt daher die Aufgabe zu Grunde, ein Schwertfalzwerk mit einem Vorderanschlag zu schaffen, welches Markierungsbildung und Falzungenauigkeiten durch Verdrehungen der Signatur verringert. Insbesondere liegt der Erfindung die Aufgabe zu Grunde, dass eine automatische Einstellung einer Anschlagskonfiguration in Abhängigkeit von Material- und Produktionsparametern ermöglicht werden soll.The invention is therefore based on the object to provide a blade folder with a front stop, which reduces marking formation and folding inaccuracies by distortions of the signature. In particular, the invention is based on the object that an automatic adjustment of a stop configuration is to be made possible depending on material and production parameters.
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
Das erfindungsgemäße Schwertfalzwerk umfasst eine einem Falzschwert und einem Paar Falzwalzen zugeordnete Transporteinrichtung, durch welche wenigstens eine Signatur vor dem Falzvorgang in einer Transportebene an eine Anschlagträgereinheit befördert werden kann. Es zeichnet sich dadurch aus, dass die Anschlagträgereinheit relativ zum Falzschwert im Wesentlichen parallel zur Transportebene bewegbar ist und wenigstens einen sich von zumindest der Positionslinie des Falzschwertes bis zu einer extremen Seitenkantenlinie durchgehend erstreckenden Vorderkantenanschlag aufweist, welcher im Wesentlichen senkrecht zur Transportebene bewegbar ist. Eine Transporteinrichtung kann dabei beispielsweise Transportrollen oder Transportbänder umfassen. Eine extreme Seitenkantenlinie wird beispielsweise durch eine maximal zu verarbeitende Signaturbreite bestimmt.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 at least one signature can be conveyed to a stop carrier unit in a transport plane before the folding operation. It is characterized in that the stop carrier unit is movable relative to the folding blade substantially parallel to the transport plane and at least one of at least the position line of the folding blade has up to an extreme side edge line continuously extending leading edge stop, which is movable substantially perpendicular to the transport plane. A transport device may include, for example, transport rollers or conveyor belts. An extreme side edge line is determined, for example, by a maximum signature width to be processed.
Für den bevorzugten Fall, dass unterhalb der Transportebene die Transporteinrichtung Transportbänder umfasst, welche durchgehend bis zu einer dem Schwertfalzwerk nachgeordneten Auslage verlaufen, damit auch ohne Kreuzbruchfalzung eine Passage der Signatur bequem und einfach möglich ist, ist es besonders vorteilhaft, dass eine Gruppe von Umlenkrollen für die Transportbänder zur Umleitung der Transportbänder am Vorderkantenanschlag entlang der von der Transportebene abgewandten Seite vorbei vorgesehen wird.For the preferred case, that below the transport plane, the transport device comprises conveyor belts, which extend continuously to a downstream of the sword folder delivery, so even without Kreuzbruchfalzung a passage of the signature is easily and easily possible, it is particularly advantageous that a group of pulleys for the conveyor belts for redirecting the conveyor belts on the leading edge stop along the side facing away from the transport plane side is provided.
Die Konstruktion des erfindungsgemäßen Schwertfalzwerkes ist bevorzugt derart ausgelegt, dass die Anschlagträgereinheit wenigstens einen im Wesentlichen senkrecht zur Positionslinie des Falzschwertes bewegbaren Seitenanschlagschlitten mit Seitenanschlägen zur Ausrichtung der Signatur entlang durch die Geometrie des Falzschwertes vorgegebenen Koordinaten aufweist. Bevorzugt ist dabei wenigstens einer der Seitenanschläge im Wesentlichen senkrecht zur Transportebene bewegbar und kann von einer Ruheposition in wenigstens eine aktive Position und zurück überführt werden. Entsprechend dem Format der zu falzenden Signatur können die Anschlagträgereinheit und/oder der Seitenanschlagsschlitten nebst den Seitenanschlägen vollautomatisch eingestellt werden.The construction of the Schwertfalzwerkes invention is preferably designed such that the stop carrier unit has at least one substantially perpendicular to the position line of the folding blade movable Seitenanschlagschlitten with side stops for aligning the signature along predetermined by the geometry of the folding blade coordinates. Preferably, at least one of the side stops is movable substantially perpendicular to the transport plane and can be transferred from a rest position into at least one active position and back. According to the format of the signature to be folded, the stop carrier unit and / or the side stop slide together with the side stops can be adjusted fully automatically.
Es ist besonders vorteilhaft, wenn zusätzlich wenigstens ein Niederhalteband oberhalb der Transportebene vorgesehen ist. Zweckmäßig wird dann eine zugeordnete Gruppe von Umlenkrollen zur Umleitung des Niederhaltebands am Vorderkantenanschlag vorbei entlang der von der Transportebene abgewandten Seite vorgesehen.It is particularly advantageous if additionally at least one hold-down band is provided above the transport plane. Appropriately, then an associated group of pulleys for redirecting the hold-down belt on the leading edge stop over along the side facing away from the transport plane side is provided.
Eine zusammengehörige Gruppe von Umlenkrollen für ein Transportband bzw. Niederhalteband ist typischerweise am Seitenanschlagsschlitten aufgenommen. Das zugeordnete Transportband bzw. Niederhalteband kann entsprechend der Bewegung des Seitenanschlagschlittens translatiert oder gleichsinnig verschoben werden. Besonders vorteilhaft ist es, wenn wenigstens eine Umlenkrolle in einer bestimmten Gruppe von Umlenkrollen im Wesentlichen senkrecht zur Transportebene bewegbar ist. Dadurch kann das zugeordnete Transportband bzw. Niederhalteband gestrafft werden, wenn sich die besagte Umlenkrolle in einer ersten Position befindet, und entspannt werden, wenn sich die Umlenkrolle in einer zweiten Position befindet, sodass eine Translation oder Verschiebung des Transportbandes gleichsinnig mit dem Seitenanschlagsschlitten erfolgen kann.An associated group of pulleys for a conveyor belt or hold-down belt is typically received on the side stop carriage. The associated conveyor belt or hold-down belt can be translated according to the movement of the side stop slide or moved in the same direction. It is particularly advantageous if at least one deflection roller in a certain group of deflection rollers is movable substantially perpendicular to the transport plane. Thereby, the associated conveyor belt or hold-down band can be tightened when the said deflection roller is in a first position and relaxed when the deflection roller is in a second position, so that a translation or displacement of the conveyor belt can take place in the same direction as the side stop carriage.
Insbesondere aufgrund der nicht vernachlässigbaren Ausdehnung oder Breite des Seitenanschlagsschlittens ist vorteilhafterweise vorgesehen, dass wenigstens ein Seitenanschlag auf dem Seitenanschlagsschlitten für einen ersten Bereich und wenigstens ein Seitenanschlag für einen zweiten Bereich möglicher Positionen zwischen einer minimalen und einer maximalen Position des Seitenanschlagsschlittens vorgesehen sind. Je nach Position des Seitenanschlagsschlittens relativ zum Falzschwert kann also ein erster Seitenanschlag oder ein zweiter Seitenanschlag zum Einsatz kommen. Bevorzugt ist wenigstens ein Seitenanschlag an einer Gruppe von Umlenkrollen an der dem Falzschwert zugewandten Seiten und/oder wenigstens ein Seitenanschlag an wenigstens einer Gruppe von Umlenkrollen an der dem Falzschwert abgewandten Seite aufgenommen. Diese Maßnahme trägt wiederum in vorteilhafter Weise der nicht vernachlässigbaren Breite der Umlenkrollen und zugeordneten Transportbänder bzw. Niederhaltebänder Rechnung, so dass eine durchgängige Variation des Formates von einem minimalen zu einem maximalen erzielt werden kann.In particular, due to the non-negligible extent or width of the side stop carriage, it is advantageously provided that at least one side stop is provided on the side stop carriage for a first region and at least one side stop for a second region of possible positions between a minimum and a maximum position of the side stop carriage. Depending on the position of the Seitenanschlagsschlittens relative to the folding blade so a first side stop or a second side stop can be used. Preferably, at least one side stop is received on a group of deflection rollers on the sides facing the folding blade and / or at least one side stop is received on at least one group of deflection rollers on the side facing away from the folding blade. This measure in turn advantageously takes into account the non-negligible width of the deflection rollers and associated conveyor belts or hold-down belts, so that a continuous variation of the format from a minimum to a maximum can be achieved.
Es ist zweckmäßig, die Bewegung der Anschlagträgereinheit und/oder die Bewegung des Vorderkantenanschlags und/oder die Bewegung wenigstens einer der Seitenanschläge mittels eines Aktuators zu erzeugen. Beispielsweise kann ein geeigneter Aktuator ein ventilgesteuerter Pneumatikzylinder oder ein Servomotor sein.It is expedient to generate the movement of the stop carrier unit and / or the movement of the leading edge stop and / or the movement of at least one of the side stops by means of an actuator. For example, a suitable actuator may be a valve-controlled pneumatic cylinder or a servomotor.
Besonders vorteilhaft ist zusätzlich das Schwertfalzwerk mit einer Steuerungseinheit zu versehen. Die Steuerungseinheit steuert dabei wenigstens einen Aktuator in Funktion wenigstens eines Signaturparameters, beispielsweise des Formates, eines Material- oder Produktionsparameters derart an, dass eine dem Format der zu falzenden Signatur entsprechende Positionierung der Anschlagträgereinheit und/oder des Vorderkantenanschlags und/oder wenigstens eines Seitenanschlags erfolgt. Durch diese Maßnahmen ist es möglich, die Markierungen an der Vorderkante der zu falzenden Signatur zu verringern. Falzungenauigkeiten durch Verdrehung der Signatur werden vermieden. Eine automatische Einstellung der Anschläge in Abhängigkeit von Material- oder Produktionsparameter in eine bestimmte Anschlagskonfiguration, insbesondere in Abhängigkeit des Formates der Signatur, ist dadurch möglich. Durch die Integration der Seitenanschläge und des Vorderkantenanschlags in eine Anschlagträgereinheit werden Kollisionen zwischen den Seitenanschlägen und dem Vorderkantenanschlag bei Veränderung ihrer Position zueinander vermieden. Die Seitenanschläge können bevorzugt 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 wenigstens eines Seitenanschlags erfolgt mit besonderem Vorteil mittels eines Aktuators.In addition, it is particularly advantageous to provide the blade folder with a control unit. In this case, the control unit controls at least one actuator as a function of at least one signature parameter, for example of the format, of a material or production parameter in such a way that the stop carrier unit and / or the front edge stop and / or at least one side stop are positioned in accordance with 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. Folding inaccuracies by twisting the signature are avoided. An automatic adjustment of the attacks depending on material or production parameters in a particular stop configuration, in particular depending on the format of the signature, is possible. The integration of the side stops and the leading edge stop in a stop carrier unit collisions between the side stops and the leading edge stop are avoided when changing their position to each other. The side stops can preferably be brought independently 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 at least one side stop is carried out with particular advantage by means of an actuator.
Beispielsweise kann ein geeigneter Aktuator ein ventilgesteuerter Pneumatikzylinder oder ein Servomotor sein.For example, a suitable actuator may be a valve-controlled pneumatic cylinder or a servomotor.

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 Vorderkantenanschlags und/oder wenigstens eines Seitenanschlagsschlittens und/oder wenigstens eines Seitenanschlages erfolgt. Durch diese Maßnahmen ist es möglich, die Markierungen an der Vorderkante der zu falzenden Signatur und Falzungenauigkeiten durch Verdrehung der 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 jedem Transportband zugeordneten Gruppen von Umlenkrollen ist es darüber hinaus möglich, eine Bewegung der Seitenkantenanschläge und der Transportbänder durchzuführen, ohne dass eine manuelle Veränderung des durchgehenden Vorderkantenanschlages erforderlich ist.Particularly advantageous, a control unit for the Schwerfalzwerk is additionally provided. The control unit controls at least one actuator as a function of 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 leading edge stop and / or at least one corresponding to the format of the signature to be folded Side stop carriage and / or at least one side stop takes place. By these measures, it is possible to reduce the markings on the leading edge of the signature to be folded and folding inaccuracies by twisting the signature. An automatic adjustment of the Stops depending on material or production parameters, in particular depending on the format of the signature, is possible. By the groups of pulleys associated with each conveyor, it is also possible to perform a movement of the side edge stops and the conveyor belts without the need to manually change the continuous 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.
