Description
Vorrichtung zum mindestens teilweisen Trennen von kontinuierlich bewegtem Streifenmaterial aus Papier od. dgl. Die Erfindung betrifft eine Vorrichtung zum mindestens teilweisen Trennen von kontinuierlich bewegtem Streifenmaterial aus Papier od. dgl. mit einer Messerwalze, deren mit einem Gegenwerkzeug zusammenwirkende Messer nachgiebig angeordnet sind.Device for at least partial separation of continuously moving Strip material made of paper od. The like. The invention relates to a device for at least partially separating continuously moving strip material made of paper od. The like. With a knife roller, whose knife interacting with a counter tool are resiliently arranged.
Bei den bekannten Vorrichtungen dieser Art sind ein oder mehrere Messer gewöhnlich weitgehend starr an der Messerwalze befestigt, beispielsweise in Schlitze der Messerwalze eingesetzt. Die Messer arbeiten entweder mit entsprechenden Messern einer Gegenwalze zusammen, so daß sich ein Scherenschnitt ergibt, oder es sind elastische bzw. elastisch gelagerte Widerlager in einer Gegenwalze vorhanden, um einen Druckschnitt auszuführen.In the known devices of this type are one or more knives usually largely rigidly attached to the knife roller, for example in slots the knife roller used. The knives either work with appropriate knives a counter roller together, so that there is a scissors cut, or they are elastic or elastically mounted abutments in an opposing roller to make a pressure cut to execute.
Weiter ist eine Messerleiste bekannt, die mittels einer Feder nachgiebig verstellbar ist, um eine .günstige Schnittführung zwischen dem Werkzeug und Gegenwerkzeug zu erzielen.A male connector is also known which is resilient by means of a spring is adjustable in order to achieve a favorable cut between the tool and the counter-tool to achieve.
Die Aufgabe der Erfindung liegt darin, eine einfache Vorrichtung zum Schneiden von Papierbahnen od. dgl. zu schaffen, die sich insbesondere zum Schneiden von weichem Papier eignet, wie es für Gesichtstücher, Handtücher und als Toilettenpapier benutzt wird.The object of the invention is to provide a simple device for To create cutting of paper webs or the like, which are particularly suitable for cutting of soft paper as it is suitable for facial tissues, hand towels and as toilet paper is used.
Gemäß der Erfindung dient als Gegenwerkzeug für das Messer der Messerwelle die zylindrische Oberfläche einer Führungswalze, und das über seine Einspannstelle vorstehende freie Ende des Messers ist derart biegsam, daß es im Bereich des Walzenspaltes unter Druck mit der Oberfläche der Führungswalze in Kontakt ist.According to the invention, the knife shaft serves as a counter tool for the knife the cylindrical surface of a guide roller, and that via its clamping point protruding free end of the knife is so flexible that it is in the area of the nip is in contact with the surface of the guide roller under pressure.
Diese Ausführung der Vorrichtung beruht auf der Erkenntnis, daß es nicht notwendig ist, für ein Messer einer Messerwalze, das von der Einspannstelle nach außen ragt, ein nachgiebiges Gegenlager vorzusehen. Es genügt als Gegenwerkzeug eine Führungswalze, deren Oberfläche nicht nachgiebig ist, wenn durch das Einspannen des Messers eine gewisse Biegsamkeit gewährleistet ist. Kommt die Schneide des Messers bei entsprechender Einstellung mit der Führungswalze in Berührung, so lassen sich sehr hohe Drücke erzeugen. Ein Brechen des Messers ist trotzdem nicht zu befürchten, weil sich die ganze Messerklinge infolge der auskragenden Lagerung biegen kann. Die geringfügigen Durchbiegungen des Messers gleichen auch kleine Ungenauigkeiten aus.This embodiment of the device is based on the knowledge that it is not necessary for a knife of a knife roller, which is from the clamping point protrudes outwards to provide a resilient counter bearing. It is sufficient as a counter-tool a guide roller, the surface of which is not compliant when it is chucked a certain flexibility of the knife is guaranteed. Comes the edge of the knife with the appropriate setting in contact with the guide roller, so can generate very high pressures. Breaking the knife is still not to be feared, because the entire knife blade can bend due to the protruding bearing. The slight deflection of the knife also compensates for minor inaccuracies the end.
Es ist jedoch zusätzlich möglich, ein einfaches, etwas elastisches Gegenwerkzeug vorzusehen, indem die Führungswalze als Widerlager von ihrer Einspannstelle auskragend eine Leiste aufweist. Bei dieser Ausbildung des Widerlagers, das also wie das Messer eingespannt ist, addieren sich die Biegungen von Messer und Widerlager bei gegenseitiger Berührung.However, it is also possible to use a simple, somewhat elastic Provide counter tool by using the guide roller as an abutment from its clamping point has a cantilevered bar. With this training of the abutment, that is as the knife is clamped, the bends of knife and abutment add up when touching each other.
Die Vorrichtung gemäß der Erfindung ist auch sehr vorteilhaft beim Schneiden von Schmirgelpapier. Hierbei läuft die Schmirgelbahn mit ihrer Schmirgelseite über die Führungsrolle, wobei also das Messer auf die Rückseite der Schmirgelpapierbahn einwirkt. Dadurch wird das Messer beim Schneiden vom Schmirgelstoff kaum beeinträchtigt und bleibt lange scharf.The device according to the invention is also very advantageous in Cutting sandpaper. Here the emery track runs with its emery side over the guide roller, with the knife on the back of the sandpaper web acts. As a result, the knife is hardly affected by the abrasive material when cutting and stays sharp for a long time.
Als weiterer Vorteil hat sich gezeigt, daß der Schneidvorgang auch noch ausreichend sauber vor sich geht, selbst wenn die Messerschneide nicht mehr ganz scharf ist. Das Schleifen des Messers kann also in größeren Abständen vorgenommen werden.Another advantage has been shown that the cutting process too is still sufficiently clean, even if the knife edge is no longer is very sharp. The knife can therefore be sharpened at longer intervals will.
In der Zeichnung ist die Erfindung veranschaulicht. Es zeigt F i g. 1 eine Teilansicht einer Schneidvorrichtung, F i g. 2 einen Schnitt nach der Linie 2-2 in F i g. 1, F i g. 3 einen Schnitt durch die Messerwalze nach der Linie 3-3 in F i g. 1, F i g. 4 einen Schnitt durch eine Führungswalze. Die in F i g. 1 und 2 dargestellte Schneidvorrichtung enthält eine Messerwalze 11 und eine Führungswalze 12. Eine Papierbahn 13 wird mittels der Walzen 29, 30 von einer Vorratsspule abgezogen und in Pfeilrichtung über die Führungswalze 12 geführt. Die Papierbahn 13 wird leicht gespannt gehalten, damit sie sich satt an die glatt geschliffene Oberfläche der Führungswalze 12 anlegt, die mit solcher Drehzahl angetrieben wird, daß ihre Umfangsgeschwindigkeit der Laufgeschwindigkeit der Papierbahn entspricht.The invention is illustrated in the drawing. It shows F i g. 1 shows a partial view of a cutting device, FIG. 2 shows a section along line 2-2 in FIG. 1, Fig. 3 shows a section through the knife roller along line 3-3 in FIG. 1, Fig. 4 shows a section through a guide roller. The in F i g. The cutting device shown in FIGS. 1 and 2 contains a knife roller 11 and a guide roller 12. A paper web 13 is drawn off from a supply reel by means of the rollers 29, 30 and guided over the guide roller 12 in the direction of the arrow. The paper web 13 is kept slightly tensioned so that it lies snugly against the smoothly sanded surface of the guide roller 12, which is driven at such a speed that its peripheral speed corresponds to the running speed of the paper web.
Die Messerwalze 11 und die Führungswalze 12 sind in einem Traggestell gelagert, das ebenfalls höhere Beanspruchungen aufnehmen kann.The knife roller 11 and the guide roller 12 are in a support frame stored, which can also take higher loads.
Die gegenläufig zur Führungswalze 12 angetriebene Messerwalze trägt beim dargestellten Ausführungsbeispiel drei Messer 18 und ist so gegenüber der Führungswalze 12 angeordnet, daß die Messerschneiden 14 im Spaltbereich zwischen den Walzen längs einer Querlinie in die Papierbahn 13 eindringen, die etwas hinter der Linie liegt, an der die Papierbahn 13 auf die Führungswalze aufläuft.The knife roller driven in the opposite direction to the guide roller 12 carries in the illustrated embodiment, three knives 18 and is opposite the guide roller 12 arranged that the knife edges 14 longitudinally in the gap area between the rollers penetrate a transverse line into the paper web 13, which lies slightly behind the line, at which the paper web 13 runs onto the guide roller.
Die drei Messer 18 sind gleichmäßig über den Umfang der Messerwalzen verteilt und in Richtung von Sehnen ihres kreisförmigen Querschnitts angeordnet, so daß also die drei Messer in einem Winkelabstand von 120° liegen. Die Messer bestehen vorzugsweise aus Werkzeugstahl. Die Schneide kann auch durch einen Hartmetallstreifen 19 gebildet werden.The three knives 18 are evenly spaced around the circumference of the knife rollers distributed and arranged in the direction of tendons of their circular cross-section, so that the three knives are at an angular distance of 120 °. The knives exist preferably made of tool steel. The cutting edge can also be cut through a hard metal strip 19 are formed.
Wie aus F i g. 3 ersichtlich ist, sind die Messer 18, die sich über die ganze Messerwalzenbreite erstrecken, mit ihrem Messerrücken durch Kopfschrauben 20 an der Messerwalze befestigt. Die Messer haben so große Bohrungen für den Durchgang der Kopfschrauben 20, daß ein Einstellen der Messer gegenüber der Führungswalze 12 möglich ist. Dieses Einstellen wird durch Stellschrauben 23 erleichtert, die auf den Messerrücken einwirken. Nach dem Einstellen werden die Messer festgezogen. Die Kopfschrauben 20 wirken über eine Druckschiene 21 auf die Messer 18 ein. Unter den Messern 18 befindet sich eine Auflageschiene 24. Ferner ist der Boden des Einschnitts in der Messerwalze unter dem freien, von der Schiene 24 bis zur Messerschneide 14 reichenden Messerteil nach außen abfallend ausgebildet, so daß das Messer, gegebenenfalls ohne Benutzung der Schiene 24, sich genügend nach unten biegen kann.As shown in FIG. 3 can be seen are the knives 18 that are about extend the entire width of the knife roller, with its knife back through cap screws 20 attached to the knife roller. The knives have such large holes for the passage of the head screws 20 that an adjustment of the knife relative to the guide roller 12 is possible. This adjustment is facilitated by adjusting screws 23, the act on the back of the knife. After adjusting, the knives are tightened. The head screws 20 act on the knives 18 via a pressure rail 21. Under The knives 18 are provided with a support rail 24. The bottom of the incision is also located in the knife roller under the free one, from the rail 24 to the knife edge 14 reaching knife part sloping outwards so that the knife, if necessary without using the rail 24, can bend down sufficiently.
Beim Arbeiten der Schneidvorrichtung laufen die Messerwalze 11 und die Führungswalze 12 in der durch Pfeile angedeuteten Richtung um. Sobald ein Messer 18 sich der Führungswalze nähert, drückt die Schneide 14 durch die Papierbahn 13 durch und kommt mit der Oberfläche der Führungswalze 12 in Berührung. Die Einstellung der Messerschneiden wird so vorgenommen, daß diese Berührung der Messerschneide 14 kürz vor der engsten Stelle des Walzenspaltes stattfindet. Während sich also das Messer bis zur engsten Stelle des Walzenspaltes weiterbewegt, biegt sich das Messer durch. Für einen fortschreitenden Schnitt, wobei also das Messer mit der Führungswalze über ihre Breite hinweg nacheinander in Berührung kommt, wird kein gerades Messer, sondern ein schraubenförmig gewundenes Messer benutzt.When the cutting device is working, the knife roller 11 and run the guide roller 12 in the direction indicated by arrows. As soon as a knife 18 approaches the guide roller, the cutting edge 14 presses through the paper web 13 and comes into contact with the surface of the guide roller 12. The setting the knife edge is made so that this touch of the knife edge 14 takes place shortly before the narrowest point of the nip. So while If the knife moves to the narrowest point of the nip, it bends Knife through. For a progressive cut, i.e. the knife with the Guide roller comes into contact one after the other across its width, will not be straight knife, but a helically wound knife is used.
Bei dem dargestellten Ausführungsbeispiel sind die Messerschneiden 14 in Abständen mit Einschnitten versehen (F i g. 1), so daß die durchlaufende Papierbahn in Querrichtung nicht völlig durchschnitten wird und in Rollenform wieder aufgewickelt werden kann. Statt dessen kann auch die Führungswalze 12 axial verteilte Umfangsrillen aufweisen. Diese Umfangsrillen können auch schraubenförmig verlaufen. Selbstverständlich ist es aber auch möglich, die einzelnen Abschnitte der Bahn völlig abzutrennen. In diesem Fall sind die einzelnen Abschnitte in bekannter Weise von der Führungswalze 12 abzunehmen.In the illustrated embodiment, the knife edges 14 provided with incisions at intervals (FIG. 1), so that the paper web running through is not completely cut in the transverse direction and wound up again in roll form can be. Instead of this, the guide roller 12 can also have axially distributed circumferential grooves exhibit. These circumferential grooves can also run helically. Of course but it is also possible to completely separate the individual sections of the web. In this case, the individual sections are in a known manner from the guide roller 12 to decrease.
F i g. 4 veranschaulicht eine Führungswalze 12a mit einer als Widerlager dienenden Leiste 26, deren Außenfläche 26 a der zylindrischen Fläche der Führungswalze 12 a angepaßt ist. Die Leiste 26 ist wie das Messer 18 auskragend mittels Kopfschrauben 27 an der Führungswalze 12a befestigt.F i g. 4 illustrates a guide roller 12a with one as an abutment serving bar 26, the outer surface 26 a of the cylindrical surface of the guide roller 12 a is adapted. The bar 26 is like the knife 18 cantilevered by means of cap screws 27 attached to the guide roller 12a.
Drei Leisten 26 sind entsprechend der Anzahl der Messer 18 der Messerwalze 11"am Umfang der Führungswalze 12a so verteilt, daß die Messerschneiden 14 beim Betrieb der Vorrichtung mit dem auskragenden, also federnden Teil der Streifen 26 in kommen. Beim Auftreffen ' der Messerschneiden addieren sich also die Biegungen von Messer und Widerlager.Three strips 26 are distributed according to the number of knives 18 of the knife roller 11 ″ on the circumference of the guide roller 12a so that the knife edges 14 come in with the cantilevered, i.e. resilient part of the strips 26 when the device is operated so the bends of the knife and abutment.
