An Independent claim is included for a method of folding signatures using the machine.

Description

Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Falzen von Signaturen gemäß dem Oberbegriff der Ansprüche 1 und 9.The present invention relates to an apparatus and a method for folding Signatures according to the preamble of claims 1 and 9.

In Rollenrotationsdruckmaschinen wird eine Materialbahn, z. B. eine Papierbahn, bedruckt und anschließend in einem Falzapparat der Druckmaschine weiter bearbeitet. In einem Falzapparat können in einem fertig bedruckten Produkt bestimmte gewünschte Falzarten erzeugt werden. In der Regel ist ferner eine Schneideeinheit vorgesehen, in der die Bahn in einzelne Signaturen geschnitten wird. Oft müssen sowohl die Bahn als Ganzes als auch die von der Bahn geschnittenen Signaturen gefalzt werden.In web-fed rotary printing machines, a material web, e.g. B. a paper web, printed and then further processed in a folder of the printing press. In one Folders can have certain desired types of folds in a finished printed product be generated. As a rule, a cutting unit is also provided, in which the web in cut individual signatures. Often, both the train as a whole and the signatures cut from the web.

In der US 5,030,193 ist ein Falzapparat beschrieben, der eine erste Falzeinrichtung zur Bildung eines ersten Falzes in einer Materialbahn entlang deren Laufbahn bildet. Dieser erste Falz wird erzeugt, indem die Bahn über einen dreieckigen, ortsfesten Falztrichter geführt und anschließend zwischen einem Zugwalzenpaar hindurch geführt wird, so dass der Falz fixiert wird. Anschließend wird die Bahn an einem Schneidezylinder in Signaturen geschnitten, die dann von einem Falzmesserzylinder einem Falzklappenzylinder zugeführt werden. Ein Falzmesser des Falzmesserzylinders schiebt die Signatur in eine Falzklappe des Falzklappenzylinders, so dass ein quer zum ersten Falz verlaufender zweiter Falz gebildet wird. Anschließend werden die Signaturen einer dritten Falzeinrichtung zugeführt. Diese umfasst eine Bandanordnung, welche die Signaturen erfasst und durch die dritte Falzeinrichtung transportiert. Die Bandanordnung verläuft in der dritten Falzeinrichtung geradlinig. An den Seiten der Bänder sind jedoch zwei ortsfeste Falztrichter vorgesehen, welche die Seiten der in die dritte Falzeinrichtung einlaufenden Signatur kontaktieren. Diese Falztrichter konvergieren in einem Winkel zu den Bändern, so dass die Außenkantenabschnitte der Signatur nach oben gelenkt werden und auf diese Weise der dritte Falz gebildet wird.In US 5,030,193 a folder is described which a first folding device for Forming a first fold in a web of material along its path. This The first fold is created by passing the web over a triangular, stationary former guided and then passed between a pair of pull rollers, so that the fold is fixed. Then the web is signed on a cutting cylinder cut, which are then fed from a folding knife cylinder to a folding jaw cylinder become. A folding knife of the folding knife cylinder pushes the signature into a folding flap of the jaw cylinder, so that a second fold running transverse to the first fold is formed. The signatures are then fed to a third folding device. This includes a band arrangement that captures the signatures and through the third Folded device transported. The belt arrangement runs in the third folding device straightforward. However, two stationary hoppers are provided on the sides of the belts, which contact the sides of the signature entering the third folder. These formers converge at an angle to the tapes so that the Outer edge portions of the signature are directed upwards and in this way the third fold is formed.

Die erste Falzeinrichtung der o. g. Schrift hat den Nachteil, dass sie nur schwer oder sogar gar nicht zum Falzen von Signaturen eingesetzt werden kann; eine Bahn muss über den Falztrichter geführt werden. Ein Nachteil der zweiten Falzeinrichtung besteht darin, dass viele bewegliche Teile nötig sind, und der Nachteil der dritten Falzeinrichtung besteht in einer komplizierten Konstruktion, bei der eine Vielzahl von Bändern unterschiedlicher Länge erforderlich sind.The first folder of the above. Writing has the disadvantage that it is difficult or even difficult cannot be used to fold signatures at all; a train has to cross the The former is guided. A disadvantage of the second folding device is that many moving parts are necessary, and the disadvantage of the third folding device is a complicated construction in which a large number of bands different Length are required.

Für eine Druckmaschine, die mit Höchstgeschwindigkeit läuft, muss meist mehr als eine bekannte Schwertfalzvorrichtung vorgesehen sein. Daher muss der Signaturenstrom in vielen Fällen aufgeteilt und abgebremst werden, wozu wiederum Zusatzvorrichtungen wie Umlenkeinrichtungen, Bremsabschnitte und Zusammenführeinrichtungen nötig sind. Diese Zusatzvorrichtungen erhöhen die Gefahr von Unregelmäßigkeiten im Falzvorgang, da die Signaturen von verschiedenen Vorrichtungen gehandhabt werden und dabei exakt in ihrer Position gehalten werden müssen.For a printing press that runs at top speed, usually more than one is required known sword folding device can be provided. Therefore, the signature stream in divided and slowed down in many cases, for which purpose additional devices such as Deflection devices, braking sections and merging devices are necessary. This Additional devices increase the risk of irregularities in the folding process, since the Signatures can be handled by different devices and exactly in theirs Position must be held.

Es ist eine Aufgabe der vorliegenden Erfindung, eine vereinfachte Vorrichtung und ein Verfahren zum Falzen von Signaturen zu schaffen, bei denen die Gefahr von Beschädigungen der Signaturen reduziert wird.It is an object of the present invention, a simplified device and a To create procedures for folding signatures where there is a risk of Damage to the signatures is reduced.

Eine erfindungsgemäße Vorrichtung zum Falzen von Signaturen umfasst hierzu eine erste Transportvorrichtung zum Transportieren eines ersten Teils einer Signatur und eine neben der ersten Transportvorrichtung angeordnete zweite Transportvorrichtung zum Transportieren eines zweiten Teils der Signatur, wobei die zweite Transportvorrichtung bezüglich der ersten Transportvorrichtung in der Weise schräg verläuft, dass der zweite Teil der Signatur in Richtung des ersten Teils der Signatur bewegt wird.For this purpose, an inventive device for folding signatures comprises a first one Transport device for transporting a first part of a signature and one next to it the second transport device arranged to the Transporting a second part of the signature, the second transport device with respect to the first transport device in such a way that the second Part of the signature is moved in the direction of the first part of the signature.

Die erste und zweite Transportvorrichtung umfassen vorzugsweise Bänder, die den jeweiligen Teil der Signatur von oben und unten erfassen. The first and second transport devices preferably comprise belts that cover the capture each part of the signature from above and below.

Da die zweite Transportvorrichtung schräg in Richtung der ersten Transportvorrichtung läuft, wird die Signatur im Bereich zwischen dem ersten Teil und dem zweiten Teil nach oben bewegt, so dass ein Falz gebildet wird.Since the second transport device is inclined towards the first transport device is running, the signature is in the area between the first part and the second part moved upwards, so that a fold is formed.

Die Falzvorrichtung umfasst ferner vorzugsweise eine Führung oder mehrere Führungen, in welche die Signaturen nach dem Verlassen der ersten und zweiten Transportvorrichtung einlaufen. Nach dem Verlassen der Führungen kann die gefalzte Signatur beispielsweise von einer Vielzahl von vertikal verlaufenden Transportbändern befördert werden.The folding device preferably further comprises one or more guides, in which the signatures after leaving the first and second transport device break in. After leaving the guides, the folded signature can, for example can be transported by a variety of vertical conveyor belts.

The second transport device can comprise an inclined belt section, which is followed by a straight band section, the straight Band section is preferably arranged upstream of the guide.

Der schräge Bandabschnitt läuft vorzugsweise mit einer etwas höheren Geschwindigkeit als die erste Transportvorrichtung. Auf diese Weise können der erste Teil und der zweite Teil der Signatur während der Bildung des Falzes mit derselben Geschwindigkeit in dieselbe Richtung bewegt werden.The sloping belt section preferably runs at a somewhat higher speed than the first transport device. In this way, the first part and the second Part of the signature during the formation of the fold at the same speed in move in the same direction.

Das erfindungsgemäße Verfahren zum Falzen von Signaturen sieht vor, dass ein erster Teil einer Signatur in eine erste Richtung transportiert wird und ein zweiter Teil der Signatur in eine zweite Richtung transportiert wird, wobei die zweite Richtung auf die erste Richtung zu schräg verläuft, so dass sich in der Signatur ein Falz bildet.The method according to the invention for folding signatures provides that a first part a signature is transported in a first direction and a second part of the signature in a second direction is transported, the second direction being in the first direction runs too sloping so that a fold forms in the signature.

Ferner kann vorgesehen sein, dass der Falz zwischen einem Zugwalzenpaar hindurchgeführt wird, das einen Bandspalt bildet. Nach dem Transportieren der Signatur kann diese ferner über eine Führung bewegt werden.It can also be provided that the fold between a pair of pull rollers is passed through, which forms a band gap. After transporting the signature it can also be moved via a guide.

Das Transportieren des zweiten Teils der Signatur erfolgt vorzugsweise mit einer etwas höheren Geschwindigkeit als das Transportieren des ersten Teils. The transport of the second part of the signature is preferably carried out with something higher speed than transporting the first part.

Das Transportieren erfolgt vorzugsweise mittels Bändern, die den jeweiligen Teil der Signatur von oben und unten erfassen.The transport is preferably carried out by means of belts that the respective part of the Capture signature from above and below.

The arrows 18, 24 and 26 and the tape running direction 20 are all parallel to one another.

Die erste Transportvorrichtung 15 umfasst ein Band 25, das sich in die Richtung des Pfeils 26 bewegt, die der Richtung des Pfeils 18 entspricht. Die erste Transportvorrichtung 15 umfasst ferner ein aus Gründen der Übersichtlichkeit nicht dargestelltes oberes Band, das die Oberseite des Signaturenteils B erfasst, während die Signatur 2 durch die erste Transportvorrichtung 15 geführt wird. Auf diese Weise wird der Signaturenteil B sicher erfasst und in die durch den Pfeil 26 angedeutete Richtung geführt.The first transport device 15 comprises a belt 25 which extends in the direction of the arrow 26 moves, which corresponds to the direction of arrow 18. The first transport device 15 also includes an upper band, not shown for reasons of clarity, the the top of the signature part B captured while the signature 2 by the first Transport device 15 is guided. In this way, the signature part B is secure detected and guided in the direction indicated by arrow 26.

Die zweite Transportvorrichtung 16 umfasst, wie in Fig. 1 gezeigt ist, einen schräg verlaufenden oberen Bandabschnitt 30, der eine erste Walze 31, eine zweite Walze 32, eine dritte Walze 33 und eine vierte Walze 34 umfasst. Zwischen der ersten und zweiten Walze 31, 32 sind zurückziehbare Bänder 35, zwischen der zweiten und dritten Walze 32, 33 nicht zurückziehbare Bänder 36 und zwischen der dritten und vierten Walze sind weitere zurückziehbare Bänder 37 angeordnet. Alle diese Bänder 35, 36, 37 verlaufen schräg auf die erste Transportvorrichtung 15 zu, so dass sie wie der untere Bandabschnitt 21 in die Richtung 22 laufen.As shown in FIG. 1, the second transport device 16 comprises an oblique one extending upper belt section 30, which a first roller 31, a second roller 32, a includes third roller 33 and a fourth roller 34. Between the first and second rollers 31, 32 are retractable belts 35 between the second and third rollers 32, 33 non-retractable belts 36 and between the third and fourth rollers are others retractable tapes 37 arranged. All of these bands 35, 36, 37 run at an angle the first transport device 15 so that it, like the lower belt section 21, into the Walk towards 22.

Der obere Bandabschnitt 30 ist in der Regel direkt über dem unteren Bandabschnitt 21 angeordnet.The upper band section 30 is usually directly above the lower band section 21 arranged.

Der erste, gerade verlaufende untere Bandabschnitt 20 ist demgemäß in einem Abstand 40 zum Band 25 angeordnet. Der Signaturenteil A einer auf dem Bandabschnitt 21 und der ersten Transportvorrichtung 15 beförderten Signatur wird durch die zurückziehbaren Bänder 35 sofort an den schräg verlaufenden Bandabschnitt 21 übergeben.The first, straight lower band section 20 is accordingly at a distance 40 arranged to band 25.

Die schräg verlaufenden Bandabschnitte 21 und 30 bewegen anschließend den Signaturenteil A auf den Signaturenteil B zu, da sich der schräg verlaufende Bandabschnitt 21 in der Position 43 an das Band 25 annähert. In der Position 43 ist der Abstand zwischen den Bändern 21 und 25 geringer als der Abstand 40. Der zweite gerade Bandabschnitt 23 ist ebenfalls in einem Abstand 41 zum Band 25 angeordnet, wobei der Abstand 41 vorzugsweise kleiner ist als der Abstand 40.The sloping band sections 21 and 30 then move the Signature part A towards signature part B, since the sloping band section 21 in position 43 approximates band 25. In position 43 is the distance between the belts 21 and 25 less than the distance 40. The second straight belt section 23 is also arranged at a distance 41 from the band 25, the distance 41 is preferably smaller than the distance 40.

Fig. 3 zeigt die Wirkung, welche das Konvergieren der Transportvorrichtungen 15 und 16 auf die Signaturen 2 hat. Ein Teil der Signaturenteile B bewegt sich innerhalb der ersten Transportvorrichtung 15 in die Richtung 26. Ein Teil der Signaturenteile A wird zwischen den schräg verlaufenden Bandabschnitten 21 und 30 in die Richtung 22 bewegt, die bezüglich der (zueinander parallelen) Richtungen 26 und 18 schräg verläuft. Auf diese Weise entsteht zwischen den beiden geführten Signaturenteilen A und B ein Falz 50.3 shows the effect of converging the transport devices 15 and 16 on the signatures 2. A part of the signature parts B moves within the first Transport device 15 in the direction 26. A part of the signature parts A is between the inclined belt portions 21 and 30 in the direction 22 that with respect to the (parallel to each other) directions 26 and 18. To this A fold 50 is thus created between the two signature parts A and B that are guided.

Alle Bänder laufen auf Walzen, die von Motoren angetrieben werden. Die Bandabschnitte 21 und 30 werden dabei jedoch etwas schneller bewegt als das Band 25, so dass der Signaturenteil A mit derselben Geschwindigkeit in die Richtung 18 bewegt wird wie der Signaturenteil B in die Richtung 26 bewegt wird. Wenn x der Winkel zwischen der Richtung 22 und der Richtung 26 und v die Geschwindigkeit des Bands 25 ist, so laufen die Bänder 22 und 30 mit einer Geschwindigkeit, die ungefähr v/cos x beträgt.All belts run on rollers that are driven by motors. However, the tape sections 21 and 30 are moved somewhat faster than the tape 25, so that the signature part A is moved in the direction 18 at the same speed as the signature part B is moved in the direction 26. If x is the angle between the direction 22 and the direction 26 and v is the speed of the belt 25, the belts 22 and 30 run at a speed which is approximately v / cos x .

Nach Bildung der Falze 50 können diese durch eine Fixierungsvorrichtung 60 fixiert werden, die ein Band 61 und ein Band 62 umfasst. Der Falz 50 kann gegen das Band 61 laufen, das sich mit derselben Geschwindigkeit wie das Band 25 bewegt, und wird in einen zwischen dem Band 61 und dem Band 62 gebildeten Spalt 63 bewegt. Dieser Spalt 63 unterstützt die Fixierung des Falzes 50. Anschließend wird die aus der ersten und zweiten Transportvorrichtung 15, 16 heraus laufende Signatur 2 durch die Bänder 61 und 62 weiter transportiert und läuft in einen Falztrichterbereich 70 ein, der hier als eine statische Führung dargestellt ist. Diese statische Führung vollendet den Falz, indem sie die Abschnitte A und B der über die statische Führung geführten Signatur 2 gegeneinander drückt. Anstelle einer statischen Führung kann jedoch zur Vollendung des Falzes auch eine dynamische Falzwalze oder eine Falzbandanordnung vorgesehen sein.After the folds 50 have been formed, they can be fixed by a fixing device 60 comprising a band 61 and a band 62. The fold 50 can against the band 61st run, which moves at the same speed as the belt 25, and is in one gap 63 formed between the belt 61 and the belt 62 moves. This gap 63 supports the fixation of the fold 50. Then the first and second Transport device 15, 16 signature 2 running out through the belts 61 and 62 further transports and runs into a former area 70, which here as a static Leadership is shown. This static guidance completes the fold by doing the Sections A and B of the signature 2 guided over the static guide against one another presses. Instead of static guidance, one can also be used to complete the fold dynamic folding roller or a folding belt arrangement can be provided.

Nach dem Verlassen des Falzbereichs 70 kann die gefalzte Signatur von weiteren Transportbändern 80 transportiert werden.After leaving the folding area 70, the folded signature can be used by others Conveyor belts 80 are transported.

Obwohl die beschriebene erste und zweite Transportvorrichtung Bänder umfasst, können auch andere Arten von Transportvorrichtungen vorgesehen sein, die einen festes Erfassen der Signaturen ermöglichen, beispielsweise eine Reihe von eng aneinandergrenzenden Walzen. Die Vorrichtung, die hier als erste Transportvorrichtung bezeichnet wurde, muss jedoch auch nicht als eine einzige Vorrichtung ausgebildet sein, die gerade verläuft, sondern kann z. B. einen ersten und einen zweiten Abschnitt umfassen, die in einem unterschiedlichen Winkel angeordnet sind. Beide Transportvorrichtungen können z. B. in ihrem zweiten Abschnitt schräg auf eine Mittelachse zu laufen. Die Bezeichnung "schräg verlaufend" bedeutet also nur, dass eine der Transportvorrichtungen bezüglich der anderen schräg verläuft.Although the described first and second transport devices comprise belts, other types of transport devices can also be provided which provide a firm grasp of signatures, for example a series of closely adjacent ones Rollers. The device, which was referred to here as the first transport device, must but also not be designed as a single device that runs straight, but can e.g. B. comprise a first and a second section, which in one different angles are arranged. Both transport devices can e.g. B. in its second section to run obliquely on a central axis. The term "oblique So "just" means that one of the transport devices is relative to the other runs obliquely.

Weiterhin kann es vorgesehen sein, dass die Bänder zum Transport des ersten Teils B und/oder des zweiten Teils A der Signaturen 2 durch Saugbänder gebildet werden, wie sie z. B. von Anlegern von Bogenrotationsdruckmaschinen her bekannt sind. Furthermore, it can be provided that the belts for transporting the first part B and / or the second part A of the signatures 2 are formed by suction tapes, as they are e.g. B. from investors of sheet-fed rotary printing presses are known.
