Abstract

The punching device has a rotating pressing element for a stepwise- operating shallow punch press which cooperates with a continuously operating rotary printing machine. In order to achieve higher operating speeds at acceptable constructional expenditure with such a device and at the same time to guarantee a constant web tension in the entire installation, it is proposed according to the invention that the rotating pressing element be designed as a cone (2) rolling over a punching plate (3) and that for stopping the printing, paper or foil web (1), which is necessary during the punching process in the punching region, compensating rollers (4) be provided in a manner known per se in web parts, running in opposite directions, upstream and downstream of the punching device, which compensating rollers can both be set at a speed corresponding to the web speed. <IMAGE>

Description

Die Erfindung betrifft eine Stanzvorrichtung gemäß Ober­begriff des Patentanspruchs 1.The invention relates to a punching device according to the preamble of patent claim 1.

Aus der Praxis bekannte Flachstanzen weisen entweder Flach- oder Walzenpreßelemente auf. Diese haben den Nachteil, daß sie mit steigender Arbeitsgeschwindigkeit einen komplizierteren Antrieb benötigen.Flat punches known from practice have either flat or roller press elements. These have the disadvantage that they require a more complicated drive with increasing working speed.

Der Erfindung liegt die Aufgabe zugrunde, eine Stanzvor­richtung der eingangs genannten Art so auszubilden, daß mit vertretbarem konstruktiven Aufwand höhere Arbeitsge­schwindigkeiten erreichbar sind und dabei eine konstante Bahnspannung in der gesamten Anlage gewährleistet ist.The invention has for its object to provide a punching device of the type mentioned so that higher working speeds can be achieved with reasonable design effort and a constant web tension is ensured in the entire system.

Diese Aufgabe wird erfindungsgemäß mit den im Kenn­zeichen des Patentanspruchs 1 angegebenen Merkmalen gelöst.This object is achieved with the features specified in the characterizing part of patent claim 1.

Die weitere Ausbildung des Erfindungsgegenstandes geht aus dem Unteranspruch hervor.The further development of the subject matter of the invention follows from the subclaim.

Der mit der Erfindung erzielte Vorteil ist in der ein­fachen Konstruktion der Vorrichtung und der damit er­reichbaren höheren Arbeitsgeschwindigkeit und konstanten Bahnspannung zu sehen.The advantage achieved with the invention can be seen in the simple construction of the device and the higher working speed and constant web tension that can be achieved thereby.

Ein Ausführungsbeispiel der Erfindung ist in der Zeich­nung dargestellt und wird nachstehend anhand einer ein­zigen Figur beschrieben, die eine perspektivische Prin­zipdarstellung der Stanzvorrichtung einschließlich der ihr vor- und nachgeordneten, über Tänzerwalzen geführten Bahnschleifen zeigt. Auf eine Darstellung der Rotations­druckmaschine, mit der die Stanzvorrichtung zusammenar­beitet, ist verzichtet worden.An embodiment of the invention is shown in the drawing and is described below with reference to a single figure, which shows a perspective schematic representation of the punching device including the upstream and downstream web loops guided over dancer rolls. An illustration of the rotary printing press with which the punching device works has been dispensed with.

Eine Druck-, Papier- oder Folienbahn 1 durchläuft eine Stanzvorrichtung, die aus einer Stanzplatte 3 und einem rotierenden Preßelement besteht, wobei letzteres von einem Kegel 3 gebildet ist, der sich auf der Stanzplatte 3 abrollt. Der Kegel 2 ist an einer Achse 11 gelagert und diese fest mit einer zu ihr senkrechten Achse 13 verbunden, deren Antrieb über ein Kegelgetriebe 18, 19 von einem Motor 22 erfolgt. Der Kegel 2 beschreibt beim Abrollen eine Kreisbahn auf einem Ring 12 und rollt über die Stanzplatte 3 in einem in der Zeichnung mit dem Win­kel α bezeichneten Bereich. Für den während des Stanz­vorganges im Stanzbereich erforderlichen Stillstand der Bahn 1 sind in gegenläufigen Bahnteilen vor und nach der Stanzvorrichtung Tänzerwalzen 4 vorgesehen, die gemein­sam mit einer der Bahngeschwindigkeit entsprechenden Ge­schwindigkeit verstellbar sind. Zu diesem Zweck sind die Tänzerwalzen 4 an einem von einem Doppelkurbelgetriebe 6, 7 hin und her bewegbaren Kreuzkopf 5 angeordnet, wobei das Kurbelgetriebe 7 über eine Hubverstellvorrichtung 9 mit einem von einem Kurvenmechanismus 10 angetriebenen Kreuzkopf 8 verbunden ist. Die Kreuzköpfe 5 und 8 sind in Linearführungen 20 bzw. 21 geführt. Der den Antrieb des Kegels 2 besorgende Motor 22 treibt über Zahnräder 14, 15, 16, 17 den Kurvenmechanismus 10 an und er ist gleichzeitig auch dazu vorgesehen, über ein Kettenrad 23 die hier nicht dargestellte Rotationsdruckmaschine anzutreiben. Ein Druck- und Stanzformatwechsel erfolgt durch Aus­wechseln eines Zahnrades 24 in einer Wechselradschiene.A printing, paper or film web 1 passes through a punching device which consists of a punching plate 3 and a rotating press element, the latter being formed by a cone 3 which rolls on the punching plate 3. The cone 2 is mounted on an axis 11 and this is firmly connected to an axis 13 which is perpendicular to it and is driven by a motor 22 via a bevel gear 18, 19. When rolling, the cone 2 describes a circular path on a ring 12 and rolls over the punching plate 3 in a region designated by the angle α in the drawing. For the standstill of the web 1 during the punching process in the punching area, dancer rollers 4 are provided in opposite web parts before and after the punching device, which can be adjusted together with a speed corresponding to the web speed. For this purpose, the dancer rollers 4 are arranged on a crosshead 5 movable back and forth by a double crank mechanism 6, 7, the crank mechanism 7 being connected via a stroke adjustment device 9 to a crosshead 8 driven by a cam mechanism 10. The cross heads 5 and 8 are guided in linear guides 20 and 21, respectively. The motor 22 which drives the cone 2 drives the cam mechanism 10 via gearwheels 14, 15, 16, 17 and is at the same time also provided for driving the rotary printing press, not shown here, via a chain wheel 23. A change of printing and punching format takes place by exchanging a toothed wheel 24 in a changing wheel rail.
