Description

Die Erfindung betrifft eine Vorrichtung zum Querperforieren von Bahnen, vorzugsweise von Papierbahnen zur Herstellung von Säcken, mit einem rotierend angetriebenen Perforiermesser und einer Nutwalze, die beide in einem Maschinengestell gelagert sind und zwischen denen die zu perforierende Bahn hindurchläuft.The invention relates to a device for cross-perforating webs, preferably of paper webs for the production of sacks, with a rotating driven Perforating knife and a grooved roller, both in a machine frame are stored and between which the web to be perforated passes.

Beispielsweise zur Herstellung von Papiersäcken werden aus einer oder mehreren übereinanderliegend zusammengeführten Bahnen durch überlappendes Einschlagen der Seitenteile und Verkleben der einander überlappenden Bereiche Papierschläuche hergestellt, von denen sog. Schlauchabschnitte abgetrennt werden, die dann üblicherweise durch Anformen von Böden zu Papiersäcken weiterverarbeitet werden.For example, paper bags are made from one or more overlapping sheets brought together by overlapping wrapping the side parts and gluing the overlapping areas of paper tubes manufactured, from which so-called hose sections are separated, the then usually further processed by forming bottoms into paper bags become.

Dabei erfolgt das Abtrennen der Schlauchabschnitte von der zuvor hergestellten Schlauchbahn dadurch, daß diese im Abstand der Schlauchabschnitte mit Querperforationen versehen wird, so daß durch besondere Abreißvorrichtungen aufeinanderfolgend die Schlauchabschnitte von der Schlauchbahn abgerissen werden können, die üblicherweise dann zu Paketen gestapelt und der Weiterverarbeitung zu Säcken zugeführt werden.The hose sections are separated from those previously produced Tubular track in that this with transverse perforations at a distance from the tube sections is provided so that successive by special tear-off devices the tube sections are torn off the tube sheet can, which are then usually stacked into packages and further processed to be fed into sacks.

In Abhängigkeit von der Dicke der Papierbahnen oder von der Anzahl der zu perforierenden Lagen der Schlauchbahn müssen die Zähne des Perforiermessers tiefer oder weniger tief in die Nutwalze eintauchen. Weiterhin ist es wünschenswert, zum Zwecke des Einziehens der zu perforierenden Bahn das Perforiermesser und die Nutwalze soweit voneinander zu entfernen, daß ein problemloses Einziehen möglich ist.Depending on the thickness of the paper webs or on the number of perforations Layers of the tube sheet must lower the teeth of the perforating knife or dip less deep into the grooved roller. Furthermore, it is desirable to Purpose of the perforating knife and the purpose of pulling the web to be perforated To remove the grooved roller so far from each other that easy pulling in is possible is.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen, mit der sich die Eintauchtiefe der Zähne des Perforiermessers in die Nutwalze entsprechend den Erfordernissen einstellen läßt.The object of the invention is therefore a device of the type mentioned To create the way in which the depth of immersion of the teeth of the perforating knife can set the grooving roller according to the requirements.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß mindestens eine Stelleinrichtung zur Veränderung des Abstands zwischen den Drehachsen des Perforiermessers und der Nutwalze vorgesehen ist.According to the invention, this object is achieved in that at least one actuating device to change the distance between the axes of rotation of the perforating knife and the grooved roller is provided.

Auf Vorrichtungen zum Querperforieren von Bahnen werden üblicherweise auch Bahnen mit Querperforationen versehen, von denen Schlauchabschnitte zur Herstellung von Säcken unterschiedlicher Formate abgerissen werden. Entsprechend diesen unterschiedlichen Formaten muß sich auch der Abstand der Querperforationen einstellen lassen. Eine derartige Einstellung ist jedoch nur dann möglich, wenn sich die Perforiermesser gegen solche unterschiedlicher Breite austauschen lassen, so daß die Perforiermesser Hüllzylinder unterschiedlicher Durchmesser überstreichen. Je nach Abschnittlänge muß also der Hüllkreis der Perforiermessers verstellt werden. Entsprechend hierzu muß auch die Lage der Nutwalze angepaßt werden, weil sich der Abstand der Achsen voneinander ändert. Nach einer bevorzugten Ausführungsform der Erfindung ist daher vorgesehen, daß eine Stelleinrichtung in der Weise einer weiten Verstellung dient, daß sich das Perforiermesser gegen ein solches äußerer Breite austauschen läßt. Devices for cross-perforating webs are usually also Provide webs with cross perforations, of which tube sections for manufacture be torn off by bags of different formats. Corresponding The spacing of the transverse perforations must also differ from these different formats let set. Such an adjustment is only possible if the perforating knives can be exchanged for those of different widths, so that the perforating knives cover envelope cylinders of different diameters. Depending on the section length, the envelope circle of the perforating knife must be adjusted become. The position of the grooved roller must also be adapted accordingly because the distance between the axes changes. According to a preferred Embodiment of the invention is therefore provided that an actuating device serves in the way of a wide adjustment that the perforating knife can be exchanged for such an outer width.

Nach einer weiteren bevorzugten Ausführungsform ist vorgesehen, daß eine andere Stelleinrichtung in der Weise der Feineinstellung dient, daß sich die Eintauchtiefe der Zähne des Perforiermessers in die Nuten der Nutwalze einstellen läßt. Diese Stelleinrichtung ermöglicht es, das rotierende Perforiermesser und die Nutwalze so aufeinander abzustimmen, daß Bahnen unterschiedlicher Dicken bzw. unterschiedlicher Lagen in der gewünschten Weise perforiert werden können. Einlagige Bahnen sind beispielsweise dann zu perforieren, wenn sog. Staffelsäcke hergestellt werden sollen und bereits mit Querperforationen versehene flache Bahnen vor der Schlauchbildung zu einer mehrlagigen Bahn zusammengeführt werden. Eine Einstellung auf unterschiedlich dicke Bahnen ist insbesondere dann erforderlich, wenn mehrlagige Schlauchbahnen perforiert werden sollen.According to a further preferred embodiment it is provided that another Actuator in the way of fine adjustment serves that the immersion depth the teeth of the perforating knife can be set in the grooves of the grooved roller. This Actuator enables the rotating perforating knife and the grooved roller to coordinate with each other that webs of different thicknesses or different Layers can be perforated in the desired manner. Single-layer sheets are to be perforated, for example, when so-called relay bags are manufactured should be and already with cross perforations flat webs in front of the Hose formation can be merged into a multi-layer web. An attitude on tracks of different thickness is particularly necessary if multilayered tube sheets are to be perforated.

Zweckmäßigerweise überdeckt die Feineinstellung einen so großen Stellbereich, daß sich das Perforiermesser und die Nutwalze außer Eingriff miteinander bringen lassen, so daß es möglich ist, die zu perforierende Bahn bei der Einrichtung der Maschine Problemlos zwischen dem Perforiermesser und der Nutwalze einzuziehen.The fine adjustment expediently covers such a large adjustment range, that the perforating knife and the grooved roller disengage from each other leave so that it is possible to perforate the web when setting up the Machine easy to pull between the perforating knife and the grooving roller.

Zweckmäßigerweise besteht jede Stelleinrichtung aus im Maschinengestell drehbar gelagerten und feststellbaren exzentrischen Wellen.Each control device expediently consists of rotatable in the machine frame stored and lockable eccentric shafts.

Nach einer besonders bevorzugten Ausführungsform ist vorgesehen, daß die Nutwalze an zwei an den Seitenteilen des Gestells schwenkbar gelagerten Lagerhebein drehbar gelagert ist, deren identische Schwenkwinkel durch eine der Grobeinstellung dienende Exzenterwelle einstellbar sind.According to a particularly preferred embodiment it is provided that the grooved roller on two pivoted bearing jacks on the side parts of the frame is rotatably mounted, the identical swivel angle by one of the rough adjustment serving eccentric shaft are adjustable.

Die der Grobeinstellung dienende Exzenterwelle kann fluchtende Fensterausschnitte beider Lagerhebel durchsetzen und sich an identischen Seiten dieser Fensterausschnitte abstützen.The eccentric shaft used for the rough adjustment can align window cutouts push through both bearing levers and on identical sides of these window cutouts support.

Zweckmäßigerweise weisen die Exzenterwellen in den Fensterausschnitten ein Spiel auf, das die Einführung erleichtert. Dieses Spiel der Exzenterwelle in dem Fensterausschnitt läßt sich vorzugsweise durch eine Stellschraube ausgleichen, zwischen der und der Abstützstelle an dem Fensterausschnitt die Exzenterwelle festgelegt ist.The eccentric shafts expediently have window cutouts Play on, which facilitates the introduction. This game of the eccentric shaft in the Window cutout can preferably be compensated by a set screw, the eccentric shaft between the and the support point on the window cutout is set.

Nach einer weiteren bevorzugten Ausführungsform ist vorgesehen, daß die Lagerhebel schwenkbar auf einer exzentrisch im Maschinengestell gelagerten, der Feineinstellung dienenden Welle gelagert sind.According to a further preferred embodiment it is provided that the bearing levers swiveling on a fine adjustment, eccentrically mounted in the machine frame serving shaft are stored.

Schließlich können die Lager des Perforiermessers und der Nutwalze in Tragstükken vorgesehen sein, die querverschieblich im Maschinengestell geführt sind, wobei eine Einrichtung zur Seitenverstellung der Tragstücke vorgesehen ist. Diese Ausführungsform trägt dem Umstand Rechnung, daß es erforderlich sein kann, eine Seitenverstellung des Perforiermessers und der zugehörigen Nutwalze vorzunehmen.Finally, the bearings of the perforating knife and the grooved roller can be in support pieces be provided, which are guided displaceably in the machine frame, wherein a device for lateral adjustment of the support pieces is provided. This Embodiment takes account of the fact that it may be necessary to use a Lateral adjustment of the perforating knife and the associated grooving roller.
