Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Längsschneiden von Bedruckstoffen in Bogen- und Rollenmaschinen mit einer Schneidvorrichtung, die als Kreismesser ausgebildet ist, dem eine rotierende Trommel gegenüberliegt, die mit einer ihre Trommelfläche ganz oder teilweise bedeckenden Auflage versehen ist, auf der der Bedruckstoff während des Schneidvorgangs aufliegt.The invention relates to a device for slitting of substrates in sheet and roll machines with one Cutting device, which is designed as a circular knife, opposite a rotating drum with a their drum surface covering all or part of the drum is provided on which the substrate during the Cutting process rests.
Bei einer bekannten Vorrichtung der angegebenen Art hat das Kreismesser eine leicht gerundete Schneide und wird, während es mit einer der Transportgeschwindigkeit des Bedruckstoffes entsprechenden Umfangsgeschwindigkeit rotiert, mit hohem Druck gegen ein unter dem Bedruckstoff auf der Trommel aufgespanntes Schneidblech oder Schneidband mit gehärteter Oberfläche, beispielsweise aus Stahl, gedrückt. Dabei wird der Bedruckstoff durch Auseinanderquetschen zerschnitten. Bedingt durch den für das Auseinanderquetschen des Bedruckstoffs erforderlichen hohen Druck nutzt sich das Messer vergleichsweise schnell ab und muß daher in relativ kurzen Zeitabständen ausgewechselt werden. Außerdem wird durch den Druck auch die Gegenfläche, also das Schneidblech oder das Schneidband, mit der Zeit zerstört und unbrauchbar. Bei Bogenschneidmaschinen hat diese Vorrichtung zudem den Nachteil, daß das Messer bei höherer Geschwindigkeit zum Springen neigt und abheben kann, wenn es nach Durchlaufen des Greiferkanals auf die Anlauffläche der Gegenfläche trifft und dort einen Stoß erhält.In a known device of the type specified Circular knives have a slightly rounded edge and will, while it with one of the transport speed of the substrate corresponding peripheral speed rotates with high pressure against an under the substrate on the drum clamped cutting plate or cutting tape with hardened Surface, for example made of steel, pressed. Here the substrate is cut by squeezing it apart. Due to the for squeezing the This uses the high pressure required for the substrate Knives comparatively quickly and must therefore be relatively be replaced at short intervals. Besides, will due to the pressure also the counter surface, i.e. the cutting plate or the cutting tape, destroyed over time and unusable. In the case of sheet-cutting machines, this device also has the disadvantage that the knife at higher speed tends to jump and can take off when it passes through of the gripper channel on the contact surface of the counter surface hits and receives a shock there.
Bei einer anderen bekannten Vorrichtung zum Längsschneiden von Bedruckstoffen an Druckmaschinen wird ein kreisförmiges, scharf geschliffenes Messer während des Rotierens mit einer Seitenfläche gegen ein feststehendes zweites Messer oder eine scharfe Kante, die beispielsweise durch eine Nut in der Trommel gebildet ist, gedrückt. Während die Schneide und die Kante oder die beiden Schneiden aneinander vorbeigleiten, wird der Bedruckstoff abgeschert. Als nachteilig bei dieser Vorrichtung hat sich herausgestellt, daß immer zwei Schneidkanten nachgeschliffen und die beiden Schneidkanten jeweils genau zueinander passend eingestellt werden müssen. Dies ist zeitaufwendig, so daß Produktionszeit verloren geht. Bei Bogenmaschinen tritt das zusätzliche Problem auf, daß die beiden Schneidkanten nach dem Durchlaufen des Greiferkanals aufgrund seitlicher Verlagerung aufeinanderstoßen und sich dabei gegenseitig beschädigen können.In another known device for slitting of printing materials on printing machines is a circular, sharpened knife while rotating with a side surface against a fixed second knife or a sharp edge, for example through a groove is formed in the drum. During the cutting edge and the edge or the two cutting edges together gliding past, the substrate is sheared off. As a disadvantage with this device it has been found that always sharpened two cutting edges and the two Cutting edges are precisely adjusted to each other Need to become. This is time consuming, so production time get lost. In the case of sheet-fed machines, this is additional Problem on that the two cutting edges after the Passing through the gripper channel due to lateral displacement collide and damage each other can.
Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art zu schaffen, die die genannten Nachteile vermeidet, schnell und einfach justierbar ist und dessen Messer eine lange Standzeit erreicht.The object of the invention is a device of the beginning to create the type mentioned, which avoids the disadvantages mentioned, is quickly and easily adjustable and its knife reached a long service life.
Die Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Patentanspruches 1 gelöst. The object is achieved by a device with the Features of claim 1 solved.
Die erfindungsgemäße Vorrichtung ist besonders leicht einstellbar, weil lediglich das Messer auf das entsprechende Schneidmaß des Bedruckstoffs eingestellt werden muß. Ein Anpassen an eine zweite Schneidkante entfällt. Das Messer verschleißt wesentlich weniger und kann nicht beschädigt werden, da es nicht an eine Gegenfläche gepreßt wird und auch nicht mit einer anderen scharfkantigen Fläche in Berührung kommt. Das Messer bewegt sich entweder frei in einer schon vorhandenen passenden Nut in der Auflage oder in einer Nut, die sich durch das Einschneiden der Schneide des Messers in die aus einem relativ weichen Material bestehenden Auflage bereits nach wenigen Umläufen unterhalb des Schneidebereichs in der Auflage gebildet hat. Das Messer kommt dann lediglich noch mit dein zu schneidenden Bedruckstoff in Kontakt und muß daher viel seltener nachgeschliffen werden. Durch das einfache und rasche Einstellen des Messers auf das gewünschte Schneidmaß wird die Rüstzeit der Maschine verkürzt. Dadurch und durch die längeren Standzeit des Messers wird die Produktionsgeschwindigkeit erhöht. Mit der erfindungsgemäßen Vorrichtung wird außerdem eine gute Qualität des Schnitts des Bedruckstoffs erzielt, da das Messer mit hoher Drehgeschwindigkeit und entgegen der Transportrichtung, ähnlich wie eine Kreissäge, rotiert.The device according to the invention is particularly easy to adjust, because only the knife on the corresponding Cutting dimension of the substrate must be set. A There is no need to adapt to a second cutting edge. The knife wears much less and cannot be damaged as it is not pressed against a counter surface and also with another sharp-edged surface in Touch comes. The knife either moves in freely an existing matching groove in the edition or in a groove formed by cutting the cutting edge of the knife in a relatively soft material existing circulation after just a few rounds of the cutting area in the support. The knife then only comes with yours to be cut Substrate in contact and therefore has to be reground much less often will. Through the simple and quick setting of the knife to the desired cutting dimension becomes the set-up time the machine is shortened. Because of this and through the longer ones The service life of the knife becomes the production speed elevated. With the device according to the invention is also achieves a good quality of the cut of the substrate, since the knife with high rotational speed and counter the direction of transport, similar to a circular saw, rotates.
Besonders geeignet ist eine Auflage, die aus einem weichen Material wie beispielsweise Gummi, Schaumstoff, einem weichen Kunststoff oder ähnlichem Material besteht. Diese Materialen bieten dem Messer wenig Widerstand, so daß es sich schon nach wenigen Umläufen eine Nut einschneiden kann, in der es geführt wird. Das Material der Auflage ist einerseits so weich, daß die Schneide bei einer Berührung mit ihr nicht abgenutzt oder beschädigt werden kann, andererseits aber auch so stabil, daß die Schultern der Nut eine Stütze für den Bedruckstoff bilden. Dies hat den Vorteil, daß die Auflage sich für jede Position des Messers eignet und nicht besonders angepaßt werden muß. A pad made of a soft material is particularly suitable Material such as rubber, foam, a soft Plastic or similar material is made. This Materials offer little resistance to the knife, so it cut a groove after just a few turns in which it is conducted. The material of the edition is on the one hand so soft that the cutting edge when touched with it cannot be worn or damaged, on the other hand but also so stable that the shoulders of the groove form a support for the substrate. This has the advantage that the pad is for every position of the knife is suitable and does not have to be specially adapted.
Erfindungsgemäß ist auch vorgesehen, daß die Auflage aus mehreren, übereinander angeordneten Schichten besteht, wobei die Schichten aus dem gleichen oder jeweils aus unterschiedlichem Material bestehen kann.According to the invention it is also provided that the edition consists of several layers arranged one above the other, where the layers are made of the same or each different material can exist.
Nach einem weiteren Vorschlag der Erfindung kann der Trommelbezug als Auflage ausgebildet sein. Die Auflage kann aber auch als Matte oder als Band auf der Trommel aufgespannt sein. Bei einer besonders vorteilhaften Ausgestaltung der Erfindung kann die Auflage auf einer Trägerschicht aufgebracht sein. Auf diese Weise läßt sich die Auflage besonders schnell und sicher auf die Trommel aufspannen. Vorzugsweise besteht eine solche Trägerschicht aus Metall. Die Metallschicht bietet einen Schutz für den Fall, daß das Messer versehentlich zu tief eingestellt wird und nach Durchschneiden der Auflage in den Trommelbezug eindringt und diesen beschädigt.According to a further proposal of the invention, the drum cover be designed as a pad. The edition can but also stretched as a mat or as a band on the drum be. In a particularly advantageous embodiment the invention can rest on a support layer be upset. In this way, the edition can clamp onto the drum particularly quickly and safely. Such a carrier layer preferably consists of metal. The metal layer offers protection in the event that Knife is accidentally set too low and after Cutting through the pad penetrates the drum cover and damaged it.
In einer weiteren erfindungsgemäßen Ausgestaltung ist vorgesehen, daß der Bedruckstoff entlang seiner Schnittflächen auf der Auflage mittels Vakuum festgehalten wird. Dazu sind Öffnungen in der Auflage vorgesehen, die an einer Saugeinrichtung angeschlossen sind.In a further embodiment according to the invention, that the printing material along its cut surfaces is held on the pad by means of vacuum. To do this Openings provided in the support, which are connected to a suction device are connected.
