- the front stop 302 may be a pivotally mounted member that reciprocates between a raised position 302.1 and a lowered position 302.2. In the raised position 302.1, the front stop 302 brakes the movement of the signature 400 to delay it until it is substantially adjacent to the following signature 401. The front stop 302 may then pivot to the lowered position 302.2 so as not to slow the movement of the signature 400 any longer so that the signatures 400, 401 may continue to move as a signature pair.

- the grippers 503 access the signatures 400 from the conveyor belt 300 by means of a conventional gripping mechanism.
- the second cylinder 502 is disposed substantially parallel to the first cylinder 501 with a center-to-center distance which allows the grippers 503 of the first cylinder 501 and the grippers 504 of the second cylinder 502 to cooperate.

- the signatures 400 and 401 are deposited on the common tape path 630, one on top of the other and not in the front end-to-back arrangement. This is advantageous because, when folding two signatures, the signatures are interlaced, which is also known as a "mom-and-dad” arrangement. This "mom-and-dad” arrangement can also be achieved with other delay mechanisms described above.
- the throughput of a printing press can be further improved by z.

Description
Die vorliegende Erfindung betrifft eine Einrichtung zur Erzeugung eines Längsfalzes gemäss dem Oberbegriff des Anspruches 1 sowie eine Verwendung nach Anspruch 7.The present invention relates to a device for producing a Längsfalzes according to the preamble of
Eine solche Einrichtung ist z.B. aus der
In der Druckindustrie wird die Geschwindigkeit, mit der Druckexemplare erzeugt werden können, laufend erhöht. Die Druck-, Gestaltungs-, Falz- und Schneidvorgänge werden häufig von einer sich im Dauerbetrieb befindlichen Maschine ausgeführt, wobei eine Bahn aus blankem Papier von einer Rolle zugeführt und ein gedrucktes, geschnittenes und gefalztes, oft als Signatur bezeichnetes Produkt ausgelegt wird. Beispielsweise bewegt sich eine Bahn in dem Prozeß zu einem fertigen Produkt durch eine Reihe von Bearbeitungseinheiten, wie u. a. durch die Druckwerke, den Trockner, die Kühleinheit, den Falzapparat und die Stapeleinrichtung. Eine dieser Bearbeitungseinheiten im Falzapparat ist eine Einrichtung zum Erzeugen eines zweiten Längsfalzes.In the printing industry, the speed at which print copies can be produced is constantly being increased. The printing, shaping, folding and cutting operations are often performed by a continuous machine, feeding a blank paper web from a roll and laying out a printed, cut and folded product, often referred to as a signature. For example, a web in the process moves to a finished product through a series of processing units, such as the like. a. through the printing units, the dryer, the cooling unit, the folder and the stacker. One of these processing units in the folder is a device for producing a second longitudinal fold.
Das Erzeugen eines zweiten Längsfalzes in Bahnlaufrichtung erfolgt z. B., nachdem die Signatur oder der Bogen von der Bahn abgeschnitten worden ist. Die Signatur kann also schon gefalzt worden sein, bevor sie den zweiten Längsfalz erhält. Gewöhnlich wird der zweite Längsfalz ausgeführt, indem z. B. die Signaturen nacheinander einem Falzmechanismus zugeführt werden, der sich auf die jeweilige Signatur herab bewegt und diese durch einen Schlitz und zwischen aufnahmebereite Walzen treibt, welche die Signatur falzen. Normalerweise werden die Signaturen, die mit einem zweiten Längsfalz versehen werden sollen, in einem 50%igen Arbeitszyklus präsentiert, d. h., daß einer Signatur von einer spezifischen Länge ein Abstand von ungefähr der gleichen Länge folgt, bis die nächste Signatur erscheint. Somit bewegt sich der Falzmechanismus auf Signaturen herab, die in der Hälfte der Zeit des Arbeitszyklus präsentiert werden.The generation of a second longitudinal fold in the web running direction z. B. after the signature or the sheet has been cut from the web. So the signature can already have been folded before it receives the second longitudinal fold. Usually, the second longitudinal fold is carried out by z. B. the signatures are successively supplied to a folding mechanism, which moves down to the respective signature and this drives through a slot and between recording ready rollers, which fold the signature. Normally, the signatures to be provided with a second longitudinal fold are presented in a 50% duty cycle, ie a signature of a specific length follows a distance of approximately the same length until the next signature appears. Thus, the folding mechanism moves down to signatures presented in half the time of the work cycle.
Mechanismen zum Erzeugen eines zweiten Längsfalzes sind im Stand der Technik bekannt. Beispielsweise offenbart
Der Prozeß der Erzeugung eines zweiten Längsfalzes ist jedoch bezüglich der Geschwindigkeit abhängig von den Geschwindigkeiten, mit welchen die Mechanismen und Signaturen bei einem 50%igen Arbeitszyklus, wie oben erwähnt, gehandhabt werden können. Um höhere Geschwindigkeiten zu erzielen, können zwei separate Falzeinrichtungen für den zweiten Längsfalz in einem Falzapparat vorgesehen und z. B. so angeordnet sein, daß jede Falzeinrichtung jede zweite Signatur falzt. Dieses Konzept erfordert jedoch zusätzliche Kosten und mehr Bauraum, so daß es bei vielen Kleineren Druckmaschinen nicht realisierbar ist und deren Geschwindigkeitspotential einschränkt.However, the process of creating a second longitudinal fold is speed dependent on the rates at which the mechanisms and signatures can be handled at a 50% duty cycle as mentioned above. To achieve higher speeds, two separate folding devices for the second longitudinal fold can be provided in a folder and z. B. be arranged so that each folding device folds every second signature. However, this concept requires additional costs and more space, so that it is not feasible in many smaller printing machines and limits their speed potential.
Es ist eine Aufgabe der vorliegenden Erfindung, eine Falzeinrichtung für den zweiten Längsfalz und ein Verfahren zu schaffen, wobei aus einem Signaturstrom ausgewählte Signaturen verzögert werden, um Signaturgruppen, wie z. B. Signaturpaare zu bilden, die dann durch ein Falzmesser von entsprechender Größe gefalzt werden, und wobei die Geschwindigkeit, mit der die Signaturen befördert werden, und die Falzgeschwindigkeit aufgrund der Bildung der Signaturgruppen variiert werden können.It is an object of the present invention to provide a folding device for the second longitudinal fold and a method wherein signatures selected from a signature stream are delayed in order to form signature groups such. To form signature pairs, which are then folded by a folding blade of appropriate size, and wherein the speed at which the signatures are conveyed, and the folding speed due to the formation of the signature groups can be varied.
Somit wird gemäß dem Verfahren und der Einrichtung nach vorliegender Erfindung eine höhere Signaturdurchlaufleistung erreicht, da mit einer einzigen Einrichtung zum Erzeugen eines zweiten Längsfalzes nur ein Falzzyklus für mehrere Signaturen ausgeführt wird. Die Signaturen werden beispielsweise zu Paaren gruppiert, dann wird mit einem einzigen Falzmesser von geeigneter Länge, z. B. einem verlängerten Falzmesser, ein zweiter Längsfalz in der Gruppe von Signaturen erzeugt. Die erfindungsgemäße Falzeinrichtung kann also Signaturpaare und somit eine größere Anzahl von Signaturen bei einem 50%igen Arbeitszyklus aufnehmen, wobei die Signaturdurchlaufleistung gesteigert wird. Die Einrichtung gemäß vorliegender Erfindung ist verwendbar in Falzapparaten oder Planoauslegern, in denen durch einen Falzmechanismus ein Querfalz in einem Bogen oder einer Signatur erzeugt werden soll.Thus, according to the method and apparatus of the present invention, a higher signature throughput is achieved since only one fold cycle for multiple signatures is performed with a single means for creating a second longitudinal fold. The signatures are grouped into pairs, for example, then with a single folding blade of suitable length, z. As an extended folding blade, a second longitudinal fold in the group of signatures generated. The folding device according to the invention can thus record signature pairs and thus a larger number of signatures in a 50% duty cycle, the signature throughput is increased. The device according to the present invention is usable in folders or Planoauslegern in which by a folding mechanism, a transverse fold is to be generated in a sheet or a signature.
Der Prozeß der Erzeugung des zweiten Längsfalzes gemäß vorliegender Erfindung umfaßt z. B. das Verzögern von wechselweise bewegten Signaturen auf ihrem Weg zur Einrichtung für den zweiten Längsfalz, so daß jede zweite Signatur zurückbewegt wird und ein kleinerer Zwischenraum hinter ihr und ein größerer Zwischenraum vor ihr entsteht. Dieser größere Zwischenraum ermöglicht es, daß ein Falzmechanismus z. B. einen 50%igen Arbeitszyklus aufrecht erhalten kann, während die Anzahl der Signaturen, die in einem gegebenen Zeitraum mit einem zweiten Längsfalz versehen werden, erhöht wird, oder während die Falzgeschwindigkeit bei der gleichen Anzahl von in einem gegebenen Zeitraum zu falzenden Signaturen reduziert wird oder eine Kombination von beiden Möglichkeiten angewandt wird. Die Signaturen, welche gleichzeitig bearbeitet werden, werden z. B. durch einen Verzögerungsprozeß zu Paaren zusammengebracht. Ein geeigneter Signaturverzögerungsmechanismus kann jedoch die Signaturen nach Wunsch gruppieren, um sie auf den Prozeß, mit dem zweiten Längsfalz versehen zu werden, vorzubereiten.The process of producing the second longitudinal fold according to the present invention comprises e.g. Example, the delay of alternately moving signatures on their way to the device for the second longitudinal fold, so that every second signature is moved back and a smaller gap behind it and a larger gap in front of it arises. This larger gap allows a folding mechanism z. B. can maintain a 50% duty cycle while increasing the number of signatures provided with a second longitudinal fold in a given period of time, or while reducing the folding speed for the same number of signatures to be folded in a given period of time or a combination of both. The signatures, which are processed simultaneously, are z. B. brought together by a delay process into pairs. However, a suitable signature delay mechanism may group the signatures as desired to prepare them for the process of being provided with the second longitudinal fold.
Somit sieht ein Ausführungsbeispiel der vorliegenden Erfindung ein Falzmesser zur Erzeugung eines zweiten Längsfalzes vor, das ungefähr zweimal die Länge einer einzelnen Signatur besitzt. Durch Steuerung der Geschwindigkeit, mit welcher der Signaturstrom dem Falzmesser zugefährt wird, und durch Verzögern gewisser Signaturen wird eine Gruppierung von Signaturen, z. B. ein Paar, gebildet, und beide Signaturen werden gleichzeitig durch ein einziges Falzmesser mit dem zweiten Längsfalz versehen, ohne daß sich die Falzgeschwindigkeit des Falzmessers erhöht.Thus, one embodiment of the present invention provides a folding blade for creating a second longitudinal fold approximately twice the length of a single signature. By controlling the speed at which the signature stream is fed to the folding blade and by delaying certain signatures becomes a grouping of signatures, e.g. As a pair formed, and both signatures are provided simultaneously by a single folding blade with the second longitudinal fold, without increasing the folding speed of the folding blade.
Die Einrichtung zur Erzeugung eines zweiten Längsfalzes kann auch ein System zum Ausgleich der dynamischen Kräfte umfassen, die durch die Bewegung des Falzmessers entstehen, wie dies in dem

Die von den Schneidzylindern 210 kommenden Signaturen 400 können z. B. durch ein Schaufelrad 220 abgebremst und dann auf einen Förderer 300 zur weiteren Bearbeitung plaziert werden. Oft umfaßt die weitere Bearbeitung der Signaturen 400 den Vorgang, daß diese mit einem zweiten Längsfalz versehen werden. Zu diesem Zweck werden die Signaturen 400 vom Förderer 300 nacheinander in eine Falzeinrichtung 240 für den zweiten Längsfalz befördert. In
Die Falzeinrichtung 240 umfaßt z. B. einen in senkrechter Richtung befestigten Rahmen 100 mit zwei horizontalen Lagerungen, die sich beide auf der gleichen Ebene befinden und Kugellager 102, 102' besitzen, in denen zwei mittige Drehachsen 20a, 30a senkrecht zum Rahmen 100 und parallel zueinander gelagert sind. Das Falzmesser 10 ist durch Gelenkarme 25 und 35 mit Drehkörpern 20 und 30, die sich jeweils um die Drehachsen 20a und 30a drehen, verbunden. Das Drehen der Drehkörper 20 und 30 bewirkt ein Hin- und Herbewegen des für den Falzvorgang verwendeten Falzmessers 10 auf einem senkrechten Pfad 22. Wenn sich das Felzmesser 10 in einer erhabenen Position befindet, bewegen sich die Signaturen 400 unter das Falzmesser 10 in Position. Dann bewegt sich das Falzmesser 10 auf die Signaturen herab und erzeugt in diesen zwischen den Zylindern 150 einen Längsfalz.The
Wie in
Die Falzeinrichtung gemäß vorliegender Erfindung umfaßt ein Falzmesser 10 von geeigneter Länge, um Signaturgruppierungen, wie z. B. zwei Signaturen, die sich in einer Vorderende-zu-Rückenende-Anordnung befinden, mit einem zweiten Längsfalz zu versehen. So können beispielsweise zwei Signaturen 400 in die Falzeinrichtung 240 eintreten und mittels des Falzmessers 10 gleichzeitig mit einem zweiten Längsfalz versehen werden. Die Gruppierungen können wechselweise erfolgen und die Länge des Falzmessers 10 kann jeweils entsprechend angepaßt werden.The folding device according to the present invention comprises a
Gemäß vorliegender Erfindung werden Signaturen 400 in einer Falzeinrichtung für den zweiten Längsfalz in Gruppen gefalzt, z. B. paarweise und nicht individuell, wie dies aus dem Stand der Technik bekannt ist. Die Signaturen 400 werden gewöhnlich z. B. von Schneidzylindern in gleichmäßig beabstandeter Anordnung zugeführt. Wie im folgenden naher beschrieben ist, wird die Zuführgeschwindigkeit der von den stromaufwärtigen Bearbeitungseinheiten zur erfindungsgemäßen Falzeinrichtung beförderten Signaturen 400 geändert, um mehrere Signaturen gleichzeitig dem Falzmesser 10 zuzuführen, wobei das Falzmesser 10 seine Falzgeschwindigkeit beibehält oder reduziert.According to the present invention,
Beim Zeitabstand T5 befinden sich drei Signaturen 400 (numeriert mit 1, 2 und 3) noch in ihrem ursprünglichen Abstand voneinander. Jedoch zwischen Zeitabstand T5 und T6 wird die Signatur 1 gemäß vorliegender Erfindung verzögert, so daß sich z. B. mit Signatur 2 ein Signaturpaar bildet. Alle Signaturen bewegen sich dann bis zum Zeitabstand T9 fort. Zwischen den Zeitabständen T9 und T10 wird jedoch Signatur 3 verzögert und ein weiteres Paar mit Signatur 4 gebildet. Obschon in
Beim Zeitabstand T10 sind die Signaturpaare 1-2 und 3-4 gebildet und befinden sich in einem Abstand voneinander derart, daß zwischen zwei Signaturpaaren ein "Paar" von Leerräumen liegt. Beim Zeitabstand T11 beginnt die Falzeinrichtung 240, in dem Paar 1-2 einen zweiten Längsfalz zu erzeugen, während das Paar 3-4 und die einzelnen Signaturen 5 und 6 sich weiterhin auf das Falzmesser 10 zu bewegen. Beim Zeitabstand T12 ist das Falzen des Signaturpaares 1-2 etwa zur Hälfte ausgeführt. Beim Zeitabstand T13 ist das Falzmesser 10 soweit angehoben, daß sich das Signaturpaar 3-4 nähern und sich somit der Signaturstrom fortsetzen kann, wie dies bei den Zeitabständen T14 und T15 dargestellt ist, usw. Wenn also bei ausgewählten Signaturen eine Verzögerung veranlaßt wird, wie das abwechselnde Verzögern der Signaturen 400 zur Bildung von Signaturpaaren, z. B. Signaturpaare 1-2, 3-4, usw., dann ist der Leerraum zwischen jedem Paar von Signaturen 400 nicht vorhanden oder minimal. Es gibt z. B. im wesentlichen keinen Leerraum zwischen den Signaturpaaren 1-2, 3-4, 5-6 usw. Die Signaturpaare werden jeweils der erfindungsgemäßen Falzeinrichtung unterbreitet, um zusammen, d. h. als Paare, einen zweiten Längsfalz zu erhalten.At the time interval T10, the signature pairs 1-2 and 3-4 are formed and are at a distance from each other such that a "pair" of voids lies between two signature pairs. At the time interval T11, the
Durch das Verzögern ausgewählter Signaturen 400, um Signaturgruppierungen, wie z. B. Paare zu bilden, ergeben sich mehrere Vorteile. Wenn beispielsweise die Zuführgeschwindigkeit der Signaturen 400 zur Falzeinrichtung 240 konstant gehalten wird und ausgewählte Signaturen 400 werden verzögert, um Paare zu bilden, kann die Falzgeschwindigkeit des erfindungsgemäßen Falzmessers 10 um 50% reduziert werden, während die gleiche Durchlaufleistung wie bei einem herkömmlichen Falzmesser für einzelne Signaturen fortbesteht. Dies ist so, weil Signaturpaare in der Hälfte der Frequenz, mit welcher individuelle Signaturen 400 (vor der Verzögerung) dem Falzmesser 10 zum individuellen Falzen unterbreitet werden, am Falzmesser 10 ankommen. Alternativ kann die Falzgeschwindigkeit des Falzmessers 10 aufrechterhalten oder teilweise reduziert werden, wenn dies mit einer entsprechenden Erhöhung der Zuführgeschwindigkeit der Signaturen 400 einher geht.By delaying selected
Wenn z. B. die Falzgeschwindigkeit des Falzmessers 10 aufrechterhalten wird und Signaturpaare mit einem Verzögerungsmechanismus gemäß vorliegender Erfindung gebildet werden, kann die Zuführgeschwindigkeit der Signaturen 400 und damit die Durchlaufleistung der Falzeinrichtung 240 verdoppelt werden. In solch einem Fall bleibt die Falzeinrichtung 240 bei einem 50%igen Arbeitszyklus (d. h., daß den Längen der Signaturpaare gleiche Längen von Leerräumen zwischen den Signaturpaaren folgen).Gemäß vorliegender Erfindung kann durch Verzögern ausgewählter Signaturen 400, die sich gruppieren und mit einer einzigen Falzbewegung gefalzt werden, tatsächlich jegliche Kombination von Zuführgeschwindigkeitserhöhung für Signaturen 400 und entsprechender Reduzierung der Falzgeschwindigkeit des Falzmessers 10 erzielt werden. Beispielsweise würde eine Erhöhung der Zuführgeschwindigkeit von 100% auf 150% eine Reduzierung der Falzgeschwindigkeit von 100% auf 75% bewirken, wenn das Falzmesser 10 in einem 50%igen Arbeitszyklus betätigt wird. Es ist auch möglich, in einem anderen als einem 50%igen Arbeitszyklus zuzuführen, indem die Geschwindigkeiten aller Signaturen geändert werden.If z. B. the folding speed of the
Wenn beispielsweise ein Signaturstrom mit einem Signaturpaar, dem ein Leerraum von der Länge einer einzigen Signatur folgt, einen 67%igen Arbeitszyklus hat, so falzt das Falzmesser 10 zwei Signaturen 400 in einem Drittel des Arbeitszyklus und wird dann um zwei Drittel des Arbeitszyklus verzögert, während sich zwei weitere Signaturen 400 (d. h. ein Signaturpaar) in Position unter das Falzmesser 10 bewegen.For example, if a signature stream having a pair of signatures followed by a single signature length space has a 67% duty cycle, the
In diesem Fall kann ein Falzmesser 10 konstruiert werden, das z. B. den Falzvorgang durch im Stand der Technik wohlbekannte zykloidische Bewegung in weniger als 50% des verfügbaren Arbeitszyklus vollendet. Somit kann das Förderband 300 das Signaturpaar in den zwei Dritteln des Zyklus, in denen das Messer über der Signatur verweilt, ein Signaturpaar in seine Position unter das Falzmesser 10 transportieren, während das Falzen in dem verbleibenden Drittel des Zyklus stattfindet und sich ein folgendes Signaturpaar dem Falzmesser 10 nähert.In this case, a
Wie oben angedeutet, umfaßt das Bearbeiten eines Stroms von Signaturen 400 in der Falzeinrichtung zur Erzeugung eines zweiten Längsfalzes gemäß vorliegender Erfindung das Verzögern auserwählter Signaturen 400 durch, z. B. einen Verzögerungsmechanismus 250 (siehe
Es können außer dem in
Beim Betrieb der Falzeinrichtung wird eine Signatur 400, die durch den ersten Zylinder 501 von stromaufwärtigen Bearbeitungseinheiten in herkömmlicher Weise übernommen wird, beispielsweise vom Greifer 503.1 an den Greifer 504.1 des zweiten Zylinders 502 übergeben. Die Umfänge der Zylinder 501, 502 sind von entsprechender Dimension, so daß z. B. bei aufeinanderfolgenden Umdrehungen die Greifer 503 des ersten Zylinders 501 mit einem anderen Greifer 504 des zweiten Zylinders 502 zusammenwirken, wie dies bei den bekannten Greifer-zu-Greifer Übergabeverfahren der Fall ist. Somit übergibt der Greifer 504.1 des zweiten Zylinders 502 die Signatur an den Greifer 503.2 des ersten Zylinders 501. Dann kann der erste Zylinder 501 zwei Signaturen auf dem Förderer 300 in einer Vorderende-Rückenende-Anordnung ablegen, d. h., im wesentlichen ohne Zwischenraum zwischen dem offenen Vorderende einer Signatur 400 und dem Rückenende einer vorhergehenden Signatur 400. Die Signaturen 400 treten also in die Falzeinrichtung 240 ein, um gemeinsam gemäß der vorliegenden Erfindung mit dem zweiten Längsfalz versehen zu werden.During operation of the folding device, a
Der erste Zylinder 501 oder der zweite Zylinder 502 kann z. B. auch eine geringe Umdrehungsexzentrizität aufweisen, so daß bei der Übertragung der Signatur von einem Zylinder auf den anderen der Greifer auf dem Zylinder, auf den die Signatur übertragen wird, sich schneller bewegt als der Greifer auf dem Zylinder, von dem die Signatur abgenommen wird. Beispielsweise bewegt sich bei der Übertragung der Signatur von Greifer 503.4 auf Greifer 504.2 der Greifer 504.2 etwas schneller als der Greifer 503.4.The
Beim Betrieb des in
Die Durchlaufleistung einer Druckmaschine kann noch weiter verbessert werden, indem z. B. ein Signaturstrom entweder vor oder nach der Bildung der oben beschriebenen Gruppierungen von Signaturen 400 geteilt wird und jeder der geteilten Signaturströme in einer erfindungsgemäßen separaten Falzeinrichtung 240 zur Erzeugung eines zweiten Längsfalzes bearbeitet wird. Somit kann die Falzgeschwindigkeit z. B. vervierfacht werden, wenn der Signaturstrom geteilt wird und von jedem Strom eine paarweise Signaturgruppierung einem separaten Falzmesser 10 zugeführt wird, wobei jedes der beiden Falzmesser 10 mit der Falzgeschwindigkeit, wie sie vor der Verzögerung herrschte, betrieben wird.The throughput of a printing press can be further improved by z.
