Description

Die Erfindung betrifft eine Schneidvorrichtung zum Schneiden einer Materialbahn in einer Falzmaschine, mit einem Zylinder, der wenigstens ein Schneidmesser aufnimmt, das mit einem Gegenwerkzeug zusammenwirkt um die genannte Materialbahn in Querrichtung zu Schneiden, wobei der genannte Zylinder wenigstens ein Perforierungsmesser oder ein Quetschmesser aufnimmt, das die Materialbahn an einer bestimmten Stelle in wenigstens einem Bereich ihrer Breite zur Bildung eines ersten Querfalzes in der Materialbahn perforiert oder quetscht.The invention relates to a cutting device for cutting a material web in a folding machine, comprising a cylinder which receives at least one cutting knife, which cooperates with a counter tool to cut said material web in the transverse direction, said cylinder accommodating at least one perforating knife or a crushing knife, the perforating or squeezing the web at a particular location in at least a portion of its width to form a first transverse fold in the web.

Eine Schneidvorrichtung dieser Art ist im Stand der Technik aus der DE-A-19927920 bekannt geworden. Diese weist zwei achsparallele und sich gegeneinander drehende Zylinder auf, zwischen denen die zu bearbeitende Materialbahn hindurchläuft. Die beiden Zylinder sind mit Schneidmesser und Schneidgegenmesser sowie Perforierungsmesser und Perforierungsgegenmesser ausgerüstet, um die Materialbahn nacheinander zu schneiden und zu perforieren. Beim Schneiden als auch beim Perforieren ist immer ein bestimmtes Werkzeugpaar miteinander in Eingriff. In einer ersten Stellung der beiden Zylinder erfolgt ein Abtrennen der Materialbahn wobei diese zwischen einem Schneidmesser und einem Schneidgegenmesser auf ihrer gesamten Breite geklemmt wird. In einer zweiten Stellung wird die Materialbahn vom zweiten Werkzeugpaar perforiert. Dazu wird die Materialbahn von dem Perforierungsmesser und dem zugeordneten Perforierungsgegenmesser bearbeitet. Bei dieser Schneidvorrichtung besteht die Schwierigkeit, dass eine Umstellung auf ein anderes Format nur mit sehr hohem Aufwand möglich wäre.A cutting device of this type is known in the art from DE-A-19927920 known. This has two axially parallel and against each other rotating cylinder, between which passes through the material web to be processed. The two cylinders are equipped with a cutting knife and a cutter, as well as perforation knives and perforation counterparts, in order to cut and perforate the material web in succession. When cutting and perforating a certain pair of tools is always engaged. In a first position of the two cylinders, a separation of the material web takes place, wherein these between a cutting blade and a cutting blade is clamped over its entire width. In a second position, the material web is perforated by the second pair of tools. For this purpose, the material web is processed by the perforation knife and the associated Perforierungsgegenmesser. In this cutting device, there is the difficulty that a conversion to another format would be possible only with great effort.

Der Erfindung liegt die Aufgabe zugrunde, eine Schneidvorrichtung der genannten Art zu schaffen, die eine wesentlich einfachere Umstellung auf andere Formate ermöglicht.The invention has for its object to provide a cutting device of the type mentioned, which allows a much easier conversion to other formats.

Die Aufgabe ist gemäss Anspruch 1 dadurch gelöst, dass das Gegenwerkzeug ein feststehendes Gegenmesser ist, das mit dem Schneidmesser und dem Perforierungsmesser oder dem Quetschmesser nacheinander in Eingriff gelangt. Bei der erfindungsgemässen Schneidvorrichtung ist lediglich ein Zylinder vorgesehen. Die Werkzeuge dieses Zylinders gelangen zum Schneiden und zum Perforieren mit dem gemeinsamen feststehenden Gegenmesser in Eingriff. Das feststehende Gegenmesser wird somit zum Schneiden als auch zum Perforieren verwendet. Für eine Umstellung auf ein anderes Format muss bei der erfindungsgemässen Schneidvorrichtung lediglich die Einbaulage des gesamten Einschubes angepasst und die dazu korrespondierende formatgerechte Drehzahl eingestellt werden. Ein Umrüsten bleibt auch dann besonders einfach, wenn gemäss einer Weiterbildung der Erfindung der Zylinder mehrere Positionen aufweist, an denen wahlweise Schneid- oder Perforierungsmesser angeordnet werden können. Da lediglich ein Zylinder erforderlich ist, ist die erfindungsgemässe Schneidvorrichtung zudem wesentlich einfacher im Aufbau und kann kostengünstiger hergestellt werden.The object is achieved according to claim 1, characterized in that the counter-tool is a fixed counter blade, which successively engages with the cutting blade and the perforation or the crushing knife. In the inventive cutting device, only one cylinder is provided. The tools of this cylinder come for cutting and perforating with the common fixed counter blade engaged. The fixed counter knife is thus used for cutting as well as for perforating. For a conversion to another format, only the installation position of the entire insert must be adjusted in the inventive cutting device and the corresponding format-appropriate speed can be adjusted. Retooling remains particularly easy even if according to an embodiment of the invention, the cylinder has a plurality of positions at which optional cutting or perforation can be arranged. Since only one cylinder is required, the inventive cutting device is also much simpler in construction and can be produced more cheaply.

Ein Schnitt sowie eine Perforierung mit höherer Qualität bei gleichzeitiger Verminderung der Maschinenbelastung und Erhöhung der Standzeit ist dann erreichbar, wenn gemäss einer Weiterbildung der Erfindung wenigstens das Schneidmesser die Materialbahn mittels einer schräg stehenden Wirkungslinie mit einem Scherenschnitt trennt. Bei einem solchen Scherenschnitt ist nur ein Teil des Messers im Eingriff mit der Materialbahn. Im Gegensatz zum bekannten Quetschschnitt, der bei der zum Stand der Technik genannten Schneidvorrichtung verwendet wird, ist nur ein Teil des Schneidmessers im Eingriff mit der Materialbahn und dem Gegenmesser und somit wird nicht die gesamte Materialbahnbreite gleichzeitig durchgetrennt. Der Scherenschnitt hat auch den Vorteil, dass die Qualität der geschnittenen Bögen wesentlich höher ist. Bei einem solchen Schnitt lassen sich Fransen vermeiden und die Entstehung von Papierstaub wird wesentlich vermindertA cut and a perforation with higher quality while reducing the machine load and increase the service life can be achieved if, according to a development of the invention, at least the cutting blade separates the material web by means of an oblique line of action with a paper cut. In such a paper cut only a part of the knife is in engagement with the material web. In contrast to the known squeezing cut, which is used in the prior art cutting device, only a part of the cutting blade is in engagement with the material web and the counter knife and thus not the entire web width is cut simultaneously. The paper cut also has the advantage that the quality of the cut sheets is much higher. With such a cut, fringes can be avoided and the generation of paper dust is significantly reduced

Unter Perforierungsmesser wird hier auch ein Messer verstanden, bei welchem die Materialbahn lediglich gequetscht und damit für den Querfalz vorbereitet wird. Die Perforation bzw. die Quetschung muss nicht zwingend über den gesamten Bereich der Materialbahn erfolgen. Es kann auch ein segmentiertes Werkzeug eingesetzt werden. In einer besonderen Ausführungsform kann zudem das Perforierungsmesser auch mit einer unregelmässigen Teilung versehen sein. Damit kann die Materialbahn bzw. die Papierbahn in bestimmten Bereichen, beispielsweise in ihrer Bahnmitte geschnitten werden. Die restliche Papierbahnbreite kann perforiert werden. Zur Vorbereitung des Querfalzes kann zudem die Materialbahn auch in einem Teilbereich gequetscht werden. Denkbar ist hier auch eine Kombination von Perforierung und Quetschung.Perforating knife is here also understood to mean a knife in which the material web is merely squeezed and thus prepared for the transverse fold. The perforation or crushing does not necessarily have to take place over the entire area of the material web. It can also be used a segmented tool. In a particular embodiment, moreover, the perforation knife can also be provided with an irregular division. Thus, the web or the web can be cut in certain areas, for example in its middle of the track. The remaining paper web width can be perforated. In addition, to prepare the transverse fold, the material web can also be squeezed in a partial area. Conceivable here is a combination of perforation and contusion.

Die in Fig. 1 gezeigte Schneidvorrichtung 10 weist einen Zylinder 2 auf, der vorzugsweise als Einschubzylinder ausgebildet ist und der in Richtung des Pfeiles 9 um eine Achse A angetrieben ist. Dieser Zylinder 2 arbeitet mit einem feststehenden Gegenmesser 4 zusammen. Der Zylinder 2 und das Gegenmesser 4 dienen zum Schneiden und Perforieren einer Materialbahn 1, insbesondere einer Papierbahn, die in Richtung des Pfeiles 8 zwischen dem Zylinder 2 und dem Gegenmesser 4 hindurchläuft. Die Materialbahn 1 wird zu Bogen 7 geschnitten, von denen einer in Fig. 6 gezeigt ist. Diese Bogen 7 weisen eine Perforation P auf, entlang der in einer nicht gezeigten und an sich bekannten Falzvorrichtung ein Querfalz gebildet wird. Die Perforation P kann auch eine sonstige Schwächung oder eine Quetschung sein.In the Fig. 1 shown cutting device 10 has a cylinder 2, which is preferably designed as a slide-in cylinder and which is driven in the direction of arrow 9 about an axis A. This cylinder 2 works with a fixed counter knife 4 together. The cylinder 2 and the counter knife 4 are used for cutting and perforating a material web 1, in particular a paper web, which passes in the direction of the arrow 8 between the cylinder 2 and the counter knife 4. The material web 1 is cut into sheets 7, one of which in Fig. 6 is shown. These sheets 7 have a perforation P along which a transverse fold is formed in a folding device not shown and known per se. The perforation P may also be some other weakening or pinching.

Der Zylinder 2 weist gemäss Fig. 1 ein Schneidmesser 3 sowie ein Perforierungsmesser 5 auf, die wie ersichtlich 180° gegeneinander versetzt und am Umfang 6 des Zylinders 2 angeordnet sind. In der Fig. 1 ist das Schneidmesser 3 mit dem Gegenmesser 4 in Eingriff. In der gezeigten Stellung wird somit die Materialbahn 1 quer durchgetrennt. Nach einer Drehung um 180° gelangt das Perforierungsmesser 5 in Eingriff mit dem Gegenmesser 4 und perforiert die Materialbahn 1. Das Gegenmesser 4 kommt somit nacheinander mit dem Schneidmesser 3 und dem Perforierungsmesser 5 in Eingriff. Für die beiden Messer 3 und 5 ist somit ein gemeinsames und feststehendes Gegenmesser 4 vorgesehen. Die mit der Schneidvorrichtung 10 von der Materialbahn 1 abgetrennten Bogen 7 weisen somit mittig eine Perforation P auf. Die Perforation P muss nicht zwingend über die gesamte Breite B des Bogens 7 erfolgen. Ein Querfalz wird auch bereits durch eine Teilperforation, einen Teilschnitt oder durch eine Quetschung ermöglicht.The cylinder 2 has according Fig. 1 a cutting blade 3 and a perforation 5 on which, as shown offset 180 ° to each other and are arranged on the circumference 6 of the cylinder 2. In the Fig. 1 the cutting blade 3 with the counter knife 4 is engaged. In the position shown thus the material web 1 is severed transversely. After a rotation of 180 °, the perforating blade 5 comes into engagement with the counter knife 4 and perforates the material web 1. The counter knife 4 thus comes successively with the cutting blade 3 and the perforation 5 in engagement. For the two knives 3 and 5 is thus a common and fixed counter knife 4 is provided. The separated with the cutting device 10 of the web 1 sheet 7 thus have a center perforation P on. The perforation P need not necessarily take place over the entire width B of the sheet 7. A transverse fold is already made possible by a partial perforation, a partial section or by a pinch.

Bei der in Fig. 2 gezeigten Schneidvorrichtung 10' ist ein Zylinder 2' mit einem Schneidmesser 3 sowie einem Perforierungsmesser 5 vorgesehen. Die beiden Messer 3 und 5 sind aber wie ersichtlich um weniger als 180° zueinander versetzt. Mit dem Zylinder 2' werden von der Materialbahn 1 Bogen abgeschnitten, bei denen die Perforation P in Längsrichtung gesehen aussermittig verläuft. Die Bogenaufteilung ist somit ungleich und dient beispielsweise zur Bildung eines Greiffalzes, an dem der Bogen in einer Öffnungstrommel geöffnet werden kann.At the in Fig. 2 shown cutting device 10 ', a cylinder 2' with a cutting blade 3 and a perforation 5 is provided. But the two blades 3 and 5 are as shown offset by less than 180 ° to each other. With the cylinder 2 'are cut from the web 1 sheet in which the perforation P seen in the longitudinal direction is eccentric. The sheet division is thus unequal and serves, for example, to form a gripping salt on which the sheet can be opened in an opening drum.

Der Zylinder 2 kann auch mehrere Perforierungsmesser 5 aufweisen, wie dies in Fig. 7b gezeigt ist. Dieser Zylinder 2'' weist jeweils um 90° versetzt ein Schneidmesser 3 sowie drei Perforierungsmesser 5 auf. Von der Materialbahn 1 werden mit diesem Zylinder 2'' Bogen 7' abgetrennt, die drei Perforierungen P aufweisen. Die Perforierungsmesser 5 sowie das Schneidmesser 3 sind vorzugsweise auswechselbar in Nuten 11 befestigt. Der Zylinder 2 gemäss Fig. 6b kann somit durch Entfernen von zwei Perforierungsmessern 5 erhalten werden. Selbstverständlich kann ohne weiteres der Zylinder 2 zum Zylinder 2'' umgerüstet werden. Möglich ist hier auch eine Ausführung mit einem Schneidmesser 3 sowie einem Perforierungsmesser 5, wobei beide Messer um 90° zueinander versetzt sind.The cylinder 2 may also have a plurality of perforating blades 5, as shown in FIG Fig. 7b is shown. This cylinder 2 '', offset by 90 °, has a cutting blade 3 and three perforation blades 5. From the material web 1 'with this cylinder 2''arc7' separated, having three perforations P. The Perforierungsmesser 5 and the cutting blade 3 are preferably removably mounted in grooves 11. The cylinder 2 according Fig. 6b can thus be obtained by removing two Perforierungsmessern 5. Of course, the cylinder 2 can be converted to the cylinder 2 '' without further ado. Also possible here is a design with a cutting blade 3 and a perforation blade 5, wherein both blades are offset by 90 ° to each other.

Der Schneidzylinder 2 arbeitet gemäss den Fig. 3 bis 5 mit einer schrägstehenden Wirklinie. Die durchlaufende Materialbahn 1 wird damit nicht schlagartig auf der gesamten Breite bearbeitet, sondern die Bearbeitung erfolgt in einer um einen bestimmten Winkelbetrag zur Laufrichtung 8 geneigten Wirkungslinie. Dies ergibt verglichen mit einer Quetschung eine reduzierte Belastung, eine verbesserte Perforation und durch die abwälzende Bewegung eine reduzierte Anregung der Maschine. Dies führt insgesamt zu einer verbesserten Qualität und gleichzeitig zu einer erhöhten Standzeit des Perforierungsmessers 5 sowie des Gegenmessers 4. Die Fig. 3 und 4 illustrieren die Schrägstellung des Zylinders 2 zur Laufrichtung 8 der Materialbahn 1. Der Winkel α der Schrägstellung ist hier aus zeichnerischen Gründen wesentlich grösser als vorgesehen gezeichnet. Der Winkel α ist vorzugsweise kleiner als 1°. Die Fig. 5 zeigt deutlich, wie Einschnitt S an einem Rand 12 der Materialbahn 1 durch einen sich allmählich und kontinuierlich vergrössernden Einschnitt S' gebildet wird. Das Schneidmesser 3 bzw. das Perforierungsmesser 5 ist somit jeweils nur über einen kurzen Bereich mit der Materialbahn 1 in Eingriff. Dieser Bereich verläuft quer zur Laufrichtung gemäss Pfeil 8 in Querrichtung gemäss Pfeil 13. Das Schneidmesser 3 bzw. das Perforierungsmesser 5 kann auch in an sich bekannter Weise leicht spiralförmig auf dem Zylinder 2 angeordnet sein. Dies ist an sich bekannt und es wird hierzu auf das Polygraph-Handbuch von Wolfgang Walenski, Seite 55, 1991 Polygraph Verlag GmbH, Frankfurt am Main verwiesen.The cutting cylinder 2 operates according to the Fig. 3 to 5 with a sloping line of action. The continuous material web 1 is thus not abruptly processed on the entire width, but the processing takes place in a by a certain angle to the direction of 8 inclined line of action. This results in a reduced load, an improved perforation and by the rolling motion a reduced excitation of the machine compared to a crushing. Overall, this leads to an improved quality and at the same time to an increased service life of the perforation blade 5 and the counter knife 4 3 and 4 illustrate the inclination of the cylinder 2 to the direction 8 of the material web 1. The angle α of the inclination is drawn here for reasons of drawing much larger than intended. The angle α is preferably less than 1 °. The Fig. 5 clearly shows how incision S is formed at an edge 12 of the material web 1 by a gradually and continuously increasing incision S '. The cutting blade 3 or the perforation blade 5 is thus in each case only over a short area with the material web 1 in engagement. This region extends transversely to the direction of arrow 8 in the transverse direction as indicated by arrow 13. The cutting blade 3 and the perforation 5 can also be arranged slightly helical on the cylinder 2 in a conventional manner. This is known per se and reference is made to the Polygraph Handbook by Wolfgang Walenski, page 55, 1991 Polygraph Verlag GmbH, Frankfurt am Main.
