Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren 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 and a method for transverse perforation of webs, preferably of paper webs for the production of bags, with a rotary driven perforating knife and a grooved roller, both of which are mounted in a machine frame and between which passes through the web to be perforated.

Beispielsweise zur Herstellung von Papiersäcken werden aus einer oder mehreren übereinander liegend zusammengeführten Bahnen durch überlappendes Einschlagen der Seitenteile und Verkleben der einander überlappenden Bereiche Papierschläuche hergestellt, von denen so genannte Schlauchabschnitte abgetrennt werden, die dann üblicherweise durch Anformen von Böden zu Papiersäcken weiterverarbeitet werden.For example, for the production of paper sacks paper hoses are produced from one or more superimposed merged webs by overlapping the side parts and bonding the overlapping areas of which so-called tube sections are separated, which are then usually further processed by molding soils to paper sacks.

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.In this case, the separation of the tube sections of the previously prepared tubular web is characterized in that it is provided at a distance of the tube sections with transverse perforations, so that by special tear-off devices successively the tube sections can be demolished by the tube web, which is then usually stacked into packages and further processing to sacks be supplied.

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 layers of the tubular web to be perforated, the teeth of the web must Immerse perforator deeper or less deep in the grooved roller. Further, for the purpose of drawing the web to be perforated, it is desirable to remove the perforating blade and the grooved roll from each other so far as to allow easy feeding.

Die US 2,148,863 zeigt eine Vorrichtung zum Versehen einer Folienbahn mit Perforationen, die allerdings der Belüftung der mit einer solchen Folienbahn verpackten Gütern dienen und keine Querperforation zum späteren Abreißen von Schlauchstücken von Schlauchbahnen darstellen. Dementsprechend ist eine Walze vorgesehen, deren Oberfläche mit Nadeln versehen ist, welche in die Folienbahn, die über eine Gegendruckwalze läuft, eintauchen. Die Achse der Gegendruckwalze ist verstellbar, um so die Eintauchtiefe der Nadeln in die Folienbahn verändern zu können.US Pat. No. 2,148,863 shows a device for providing a film web with perforations, which, however, serve for the ventilation of the goods packed with such a film web and do not represent a transverse perforation for the later tearing off of hose pieces of tubular webs. Accordingly, a roller is provided, the surface of which is provided with needles, which dip into the film web, which runs over a counter-pressure roller. The axis of the platen roller is adjustable so as to be able to change the depth of immersion of the needles in the film web.

Insbesondere US 2,748,863 offenbart eine Vorrichtung zum Perforieren von Bahnen zur Herstellung von Säcken mit einem rotierend angetriebenen Perforiermesser und einer Nutwalze, die beide in Maschinengestell gelagert sind und zwischen denen die zu perforierende Bahn hindurch läuft, wobei mindestens eine Stelleinrichtung zur Veränderung des Abstands zwischen den Drehachsen des Perforiermessers und der Nutwalze vorgesehen ist, wobei die Stelleinrichtung in der Weise einer weiten Verstellung dient.In particular, US 2,748,863 discloses a device for perforating webs for the production of bags with a rotary driven perforator and a grooved roller, both of which are mounted in machine frame and between which runs the web to be perforated, wherein at least one adjusting means for varying the distance between the axes of rotation the perforating blade and the grooved roller is provided, wherein the adjusting device serves in the manner of a wide adjustment.

US 2,748,863 offenbart auch ein Verfahren zur Einstellung in einer Vorrichtung zum Perforieren von Bahnen zur Herstellung von Säcken mit einem rotierend angetriebenen Perforiermesser und einer Nutwelze, die beide in einem Maschinengestell gelagert sind und zwischen denen die zu perforierende Bahn hindurchläuft, wobei mit mindestens einer Stelleinrichtung der Abstand zwischen den Drehachsen des Perforiermessers und der Nutwalze verändert wird, mit welcher die Lage der Nutwalze auf die Durchmesser der Zylinder angepasst wird, wobei mit einer Stelleinrichtung eine weite Verstellung vorgenommen wird.US 2,748,863 also discloses a method of adjustment in a device for perforating webs for producing bags with a rotary driven perforator and a Nutwelze, both of which are mounted in a machine frame and between which passes through the web to be perforated, wherein at least one adjusting device of Distance between the axes of rotation of the Perforiermessers and the groove roller is changed, with which the position of the grooved roller is adapted to the diameter of the cylinder, wherein with a setting device a wide adjustment is made.

Auf Vorrichtungen zum Querperforieren von Bahnen werden üblicherweise auch Bahnen mit Querperforationen versehen, von denen Schlauchabschnitte zur Herstellung von Säcken unterschiedlicher Formate abgerissen werden.On devices for transverse perforation of webs also usually provided with transverse perforations webs, of which tube sections are torn off for the production of bags of different formats.

Die Aufgabe der vorliegenden Erfindung ist es eine Vorrichtung vorzuschlagen, bei der sich gemäß des gewünschten Formates der späteren Säcke der Abstand der Querperforationen einstellen lässt.The object of the present invention is to propose a device in which the distance of the transverse perforations can be set according to the desired format of the later sacks.

Die Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 und durch einem Verfahren mit den Merkmalen des Anspruchs 9.The object is achieved by a device having the features of claim 1 and by a method having the features of claim 9.

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. Erfindungsgemäß ist daher vorgesehen, dass eine Stelleinrichtung in der Weise einer weiten Verstellung dient, dass sich das Perforiermesser gegen ein solches äußerer Breite austauschen lässt.However, such an adjustment is only possible if the perforating blades can be exchanged for such different widths, so that the perforating blades cover enveloping cylinders of different diameters. Depending on the section length, the enveloping circle of the perforating blade must be adjusted. Accordingly, the position of the groove roller must be adjusted because the distance between the axes change from each other. The invention is therefore intended that a Serving means in the manner of a wide adjustment is that the perforator can be replaced with 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 adjusting device is used in the manner of fine adjustment, that can be set the immersion depth of the teeth of the Perforiermessers in the grooves of the grooved roller. This adjusting device makes it possible to match the rotating perforating blade and the grooved roller to one another so that webs of different thicknesses or different layers can be perforated in the desired manner. Single-layer webs are to be perforated, for example, when so-called staggered sacks are to be produced and flat webs already provided with transverse perforations are brought together before the hose formation to form a multilayer web. A setting on different thickness webs is particularly necessary when multi-layer tubular webs 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.Conveniently, the fine adjustment covers such a large adjustment range that the perforating blade and the grooved roller can be disengaged from each other so that it is possible to easily retract the web to be perforated when setting up the machine between the perforating blade and the grooved roller.

Zweckmäßigerweise besteht jede Stelleinrichtung aus im Maschinengestell drehbar gelagerten und feststellbaren exzentrischen Wellen.Conveniently, each actuator consists of rotatably mounted and lockable eccentric shafts in the machine frame.

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 is rotatably mounted on two bearing levers pivotally mounted on the side parts of the frame, whose identical pivoting angle can be adjusted by means of an eccentric shaft serving for coarse adjustment.

Die der Grobeinstellung dienende Exzenterwelle kann fluchtende Fensterausschnitte beider Lagerhebel durchsetzen und sich an identischen Seiten dieser Fensterausschnitte abstützen.Serving the coarse adjustment eccentric shaft can pass through the aligned cutouts of both bearing levers and be supported on identical sides of these windows.

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.Conveniently, the eccentric shafts in the window openings on a game that facilitates the introduction. This game of eccentric shaft in the Window cutout can preferably be compensated by an adjusting screw, between which and the support point on the window pane, the eccentric shaft is fixed.

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 are pivotally mounted on an eccentrically mounted in the machine frame, the fine adjustment serving shaft.

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 Perforiermessers and the grooved roll may be provided in Tragstükken which are guided transversely displaceable in the machine frame, wherein means for lateral adjustment of the support pieces is provided. This embodiment takes into account the fact that it may be necessary to make a lateral adjustment of the Perforiermessers and the associated groove roller.

In ihren unteren Bereichen sind die Tragstücke 3, 4 mit Zapfen 7, 8 versehen, die ebenfalls entsprechende Durchbrüche der Seitenteile 1, 2 durchsetzen. Zur Aussteiffung können die Tragstücke 3, 4 durch nicht dargestellte Traversen miteinander verbunden sein. Zur Seiteneinstellung der Tragstücke ist an dem Seitenteil 1 ein mit einem Drehknopf versehenes Wellenstück 9 drehbar, aber axial unverschieblich gelagert, dessen Endbereich mit einem Gewinde versehen ist und in eine Gewindebohrung des Tragstücks 3 eingeschraubt ist, so daß durch Betätigung des Drehknopfs eine Seitenverstellung der Tragstücke 3, 4 relativ zu den Seitengestellen 1, 2 möglich ist.On the plate-shaped side parts 1, 2 of the machine frame plate-shaped supporting pieces 3, 4 are supported. These support pieces are provided in their upper regions fixed with aligned pipe sections 5, 6, which are guided displaceably in these adapted openings of the side parts 1, 2. In their lower areas, the supporting pieces 3, 4 are provided with pins 7, 8, which also pass through corresponding openings of the side parts 1, 2. For Aussteiffung the support pieces 3, 4 may be interconnected by trusses, not shown.

The perforator 10 is equipped with a sawtooth-like cutting edge. On the tube piece 6 superior shaft journal of the rotatably mounted Perforiermessers 10, a pulley 11 is keyed, which is driven by a belt or toothed belt 12.

In den Tragstücken 3, 4 ist eine der Feineinstellung dienende Exzenterwelle 13 gelagert, deren rechtes Ende das rechte Seitengestell 1 in einer Bohrung durchsetzt. Endseitig ist auf die Exzenterwelle 13 zu deren Verstellung ein Betätigungshebel 14 aufgesetzt. Auf der Exzenterwelle 13 sind zwei Hebel 15, 16 schwenkbar gelagert, an deren oberen Enden die endseitigen Wellenzapfen der frei drehbaren Nutwalze 17 gelagert sind. Die Nutwalze 17 ist mit Ringnuten versehen, in die die Zähne des Perforiermessers 10 eintauchen können. Die Hebel 15, 16 sind in ihrem mittleren Bereich zwischen der Lagerung der Nutwalze 17 und der Lagerung auf der Exzenterwelle 13 mit einem etwa rechteckigen fensterartigen Durchbruch 20 versehen. Diesen Durchbruch 20 durchsetzt eine Exzenterwelle 21, die in der darstellten Weise in den Seitengestellen 1, 2 drehbar gelagert ist. In abgewinkelte Konsolen 22 der Hebel 15, 16 sind Stellschrauben 23 eingeschraubt, deren verbreiterten tellerartigen Köpfe sich auf der Exenterwelle 21 abstützen und diese zwischen sich und einer Seite der Fensterausschnitte 20 spielfrei einfassen.In the support pieces 3, 4 a fine adjustment serving eccentric shaft 13 is mounted, whose right end passes through the right side frame 1 in a hole. End side, an actuating lever 14 is placed on the eccentric shaft 13 for the adjustment thereof. On the eccentric shaft 13, two levers 15, 16 are pivotally mounted, at the upper ends of the end-side shaft journals of the freely rotatable groove roller 17 are mounted. The groove roller 17 is provided with annular grooves into which the teeth of the perforating 10 can dip. The levers 15, 16 are provided in their middle region between the storage of the grooved roll 17 and the bearing on the eccentric shaft 13 with an approximately rectangular window-like opening 20. This breakthrough 20 passes through an eccentric shaft 21 which is rotatably supported in the illustrated frames in the side frames 1, 2. In angled brackets 22 of the levers 15, 16 screws 23 are screwed, the widened plate-like heads are supported on the eccentric shaft 21 and this free play between itself and one side of the window cutouts 20.

Die Exenterwelle 21 weist, wie insbesondere aus Fig. 2 ersichtlich ist, eine große Exzentrizität auf, so daß durch deren Drehung das Perforiermesser 10 in und außer Eingriff mit der Nutwalze gebracht werden kann.The eccentric shaft 21 has, as shown particularly in FIG. 2 can be seen, a large eccentricity, so that by the rotation of the perforator 10 can be brought into and out of engagement with the grooved roller.

Nach einer Voreinstellung durch die Exenterwelle 21 kann eine Feineinstellung der Eintauchtiefe des Perforiermessers 10 in die Ringnuten der Nutwalzen 17 durch Drehung der Exenterwelle 13 erfolgen, die eine geringere Exzentrizität aufweist.After presetting by the eccentric shaft 21, a fine adjustment of the immersion depth of the Perforiermessers 10 in the annular grooves of the grooved rollers 17 by rotation of the eccentric shaft 13 take place, which has a lower eccentricity.

Die der Grobeinstellung dienende Exenterwelle 21 ist durch einen Betätigungshebel 25 verdrehbar, der auf ihrem das Seitengestell 1 durchsetzenden Wellenzapfen befestigt ist.The coarse adjustment serving eccentric shaft 21 is rotated by an actuating lever 25 which is fixed on its side frame 1 passing through shaft journals.

Die jeweils durch die Exenterwellen 13 und 21 eingestellte Exzentrizität läßt sich durch Klemmstücke 26, 27 fixieren. Das Klemmstück 26 ist durch ein Halteteil mit dem Seitengestell 1 verbunden, während das Klemmstück 27 ein Halteteil 28 aufweist, das das Seitengestell 1 in einem Durchbruch durchsetzt und an dem Tragstück 3 befestigt ist.The eccentricity set by the eccentric shafts 13 and 21 can be fixed by clamping pieces 26, 27. The clamping piece 26 is connected by a holding part with the side frame 1, while the clamping piece 27 has a holding part 28 which passes through the side frame 1 in an opening and is secured to the support piece 3.

In Fig. 2 ist der Durchlauf der zu perforierenden Bahn 30 durch die Vorrichtung schematisch angedeutet. Der Drehkreis des Perforiermessers 10 ist durch einen Hüllkreis 31 dargestellt.In Fig. 2, the passage of the web 30 to be perforated is schematically indicated by the device. The turning circle of the perforating blade 10 is represented by an enveloping circle 31.

Das Perforiermesser 10 ist in üblicher Weise durch Messerträger 33 auf der Messerwelle 34 befestigt.The perforating blade 10 is fixed in the usual way by blade carrier 33 on the blade shaft 34.

Durch entsprechende Auswahl der Messerträger 33 kann der wirksame Durchmesser des Hüllkreises der Messer den Abschnittlängen der zu perforierenden Bahn angepaßt werden. Die Anpassung kann durch den Einbau breiterer oder schmalerer Perforiermesser oder aber auch durch Anpassung der Messerträger 33 an den radialen Abstand der Perforiermesserschneiden von der Drehachse erfolgen.By appropriate selection of the knife carrier 33, the effective diameter of the enveloping circle of the knives can be adapted to the section lengths of the web to be perforated. The adaptation can be done by installing wider or narrower perforating or by adjusting the blade carrier 33 to the radial distance of the Perforiermesserschneiden from the axis of rotation.
