Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Querschneiden einer kontinuierlich vorbewegten Pa- r>r> pierbahn in Stücke gleicher, vorher bestimmter Länge mit gesondert an einer umlaufenden Messerwalze sitzenden Schneidelementen, welche die über die Umfangsfläche einer ebenfalls umlaufenden Gegenschneidwalze geführte Papierbahn zerschneiden, wobei h|> an der Gegenschneidwalze in gleichen Abständen bewegliche, mit den Kanten der Schneidelemente zusammenwirkende Schneidunterlagen vorgesehen sind.The invention relates to a device for cross-cutting a continuously vorbewegten patent r> r> pierbahn in pieces of equal, predetermined length separately seated on a revolving knife roll cutting elements, which cut the guided over the peripheral surface of a likewise rotating counter-cutting roll paper web, h | > Movable cutting pads that interact with the edges of the cutting elements are provided on the counter-cutting roller at equal intervals.
Bei einer bekannten Vorrichtung der eingangs ge- *>Γ> nannten Art sind den spitzen Kanten der Schneidelemente gegenüberliegend nachgiebige Schneidunterlagen angeordnet, die stets parallel zu den Schneidkanten der Schneidelemente angeordnet sein sollen. Treten jedoch — wie im Betrieb üblich — hohe Schneidkräfte auf, dann können diesen die Schneidunterlagen örtlich nachgeben, so daß ihre parallele Ausrichtung zu den Schneidkanten nicht gewahrt bleibtIn a known device of the overall *>Γ> type called are arranged the pointed edges of the cutting elements opposite resilient cutting surfaces, which should always be arranged in parallel to the cutting edges of the cutting elements. However, if high cutting forces occur - as is customary in operation - then the cutting pads can give way locally so that their parallel alignment to the cutting edges is not maintained
Ausgehend von diesem Stande der Technik ist es Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art zu schaffen, die auch bei hohen Schneidkräften eine exakt parallele Ausrichtung der Schneidkanten zu den Schneidunterlagen ermöglichtBased on this prior art, it is the object of the invention to provide a device of the initially called type to create an exactly parallel alignment of the even with high cutting forces Allows cutting edges to the cutting pads
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schneidunterlagen um einen von der Gegenschneidwalze getragenen Lagerzapfen in einer zu der Gegenschneidwalze radialen Ebene schwenkbar angebracht sind, wobei der Lagerzapfen in der Symmetrieebene der Gegenschneidwalze und senkrecht zum Radius der Gegenschneidwalze angeordnet istAccording to the invention, this object is achieved by that the cutting pads around a bearing journal carried by the counter-cutting roller in one of the Counter-cutting roller are mounted pivotably in the radial plane, the bearing journal in the plane of symmetry of the counter-cutting roller and perpendicular to the Radius of the counter-cutting roller is arranged
Es ist zwar eine weitere Vorrichtung zum Zerschneiden eines fortlaufenden Papierbandes bekannt (US-PS 34 25 307), bei der ein Schneidkopf, der an seinen vier Ecken vier Schneidelemente aufweist, mittels einer Lagerwelle schwenkbar gelagert ist. Dieser Aufbau unterscheidet sich jedoch grundsätzlich vom Gegenstand der Erfindung, bei dem nicht die Messerwalze, sondern die Gegenschneidwalze eine Schwenkbewegung durchführen kann. Durch die erfindungsgemäße Anordnung ergeben sich eine Reihe von Vorteilen, die insbesondere darin liegen, daß jede Schneidunterlage auf einem festen, massiven Lagerzapfen so angebracht ist, daß sie eine Schwenkbewegung um diesen durchführen kann und somit selbsttätig immer der zugehörigen Schneidkante folgt und hierbei exakt parallel zu dieser ausgerichtet bleibt. Diese Schwenkbewegung ist auch bei größeren Schneidkräften möglich, da der Lagerzapfen massiv aufgebaut wird und erst dann seine Funktion nicht mehr erfüllen kann, wenn er bei extremen Kräften aus seiner Halterung herausgerissen wird. Dies gilt auch für die anderen Teile des Schwenkmechanismus, insbesondere die Schneidunterlage und für Haltezapfen, die Gegenstand weiterer Ausgestaltungen der Erfindung sind. Schließlich läßt sich auch das Ausmaß der jeweiligen Schwenkbewegung sehr genau einstellen, indem das Spiel der Haltezapfen in entsprechender Weise ausgelegt wird.There is a further device for cutting a continuous paper tape known (US-PS 34 25 307), in which a cutting head, which has four cutting elements at its four corners, by means of a Bearing shaft is pivotably mounted. However, this structure is fundamentally different from the object of the invention, in which not the knife roller, but the counter-cutting roller has a pivoting movement can perform. The inventive arrangement results in a number of advantages that in particular lie in the fact that each cutting pad is mounted on a solid, solid bearing pin is that it can perform a pivoting movement around it and thus always automatically associated cutting edge follows and remains aligned exactly parallel to this. This pivoting movement is also possible with larger cutting forces, since the bearing journal is built up solid and only can then no longer fulfill its function if it is torn out of its holder under extreme forces will. This also applies to the other parts of the swivel mechanism, in particular the cutting pad and for retaining pins that are the subject of further embodiments of the invention. Finally lets the extent of the respective pivoting movement can also be adjusted very precisely by the play of the Retaining pin is designed in a corresponding manner.

Im folgenden ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben. Darin zeigtIn the following an embodiment of the invention is described with reference to the drawing. In it shows
Fig. 1 eine teilweise im Schnitt dargestellte Vorderansicht der Vorrichtung,Fig. 1 is a partially sectioned front view the device,
Fig. 2 eine teilweise im Schnitt gezeigte Seitenansicht der Vorrichtung undFig. 2 is a side view partially shown in section the device and
F i g. 3 eine Ansicht im Schnitt entlang der Linie 111-111 in F i g. 2.F i g. 3 is a sectional view taken along line 111-111 in Fig. 2.
Die dargestellte Vorrichtung weist eine Messerwalze und eine Gegenschneidwalze auf.The device shown has a knife roller and a counter-cutting roller.
Die Messerwalze hat eine mittig angeordnete Nabe 1 mit beiderseits daran angesetzten Wellenzapfen 2, 3. Die Nabe 1 hat beispielsweise sechs in gleichmäßigen gegenseitigen Abständen parallel zur Achse der Wellenzapfen verlaufende Nuten 4. In jeder Nut 4 ist ein quadratischen Querschnitt aufweisender Schneidstab 5 mittels Klemmen 6 und 7 befestigt.The knife roller has a centrally arranged hub 1 with shaft journals 2, 3 attached to it on both sides. The hub 1 has, for example, six equally spaced parallel to the axis of the Grooves 4 running through shaft journals. In each groove 4 there is a cutting rod 5 with a square cross-section attached by means of clamps 6 and 7.
Die Länge und der Durchmesser der Wellenzapfen 2 und 3 sind so bemessen, daß diese sich beim Aufsetzen der einzelnen Schneidstäbe oder Messer 5 auf die Gegenschneidwalze etwas durchzubiegen vermögen.The length and the diameter of the shaft journals 2 and 3 are dimensioned so that they are when placed of the individual cutting rods or knives 5 are able to bend a little on the counter-cutting roller.
Die Wellenzapfen sind mit ihren Enden mittelsThe shaft journals are by means of their ends
Pendelkugellagern 10, 11 in Lagerböcken 8 bzw. 9 gelagert Die Messerwalze ist mittels eines etwa am Wellenzapfen 3 angreifenden Antriebs mit einer bestimmten Drehzahl antreibbar.Self-aligning ball bearings 10, 11 in bearing blocks 8 and 9, respectively Shaft journal 3 attacking drive can be driven at a certain speed.
Die Gegenschneidwalze 12 hat ein Mittelstück 13, an welchem eine Anzahl von Haltesegrnenten 14 befestigt ist. Die Haltesegmente 14 tragen jeweils einen Lagerzapfen 15 und zwei zylindrische Haltezapfen 16, 17. Eine Schneidunterlage 18 stützt sich mit einer halbzylindrischen Hohlfläche auf dem Lagerzapfen 15 i< > ab und isi mit zwei zylindrischen Bohrungen auf die Haltezapfen 16,17 aufgeschoben. Der Durchmesser der Bohrungen ist etwas größer als der der Haltezapfen, so daß die Schneidunterlage 18 eine Pendelbewegung um den Lagerzapfen 15 ausführen kann. Die Gegenschneidwalze hat eine Mittelbohrung für die Aufnahme einer Welle 19, über welche sie mit einer bestimmten Drehzahl antreibbar istThe counter-cutting roller 12 has a center piece 13 to which a number of retaining segments 14 are attached is. The holding segments 14 each carry a bearing pin 15 and two cylindrical holding pins 16, 17. A cutting pad 18 is supported with a semi-cylindrical hollow surface on the bearing pin 15 i < > from and isi pushed onto the retaining pins 16, 17 with two cylindrical bores. The diameter of the The bore is slightly larger than that of the retaining pin, see above that the cutting pad 18 can perform a pendulum movement about the bearing pin 15. The counter cutting roller has a central hole for receiving a shaft 19, via which it is with a certain Speed is drivable
Die beschriebene Vorrichtung arbeitet in folgender Weise: Ein fortlaufendes Papierband 20 wird über eine _>« Zubringerrolle 21 der Gegenschneidwalze 12 zugeführt. Die dem Papierband 20 von der Zubringerrolle 21 erteilte Zulaufgeschwindigkeit ist etwas kleiner als die Umfangsgeschwindigkeit der Gegenschneidwalze 12 und derart auf die Umlaufgeschwindigkeit der Messer- 2 > walze abgestimmt, daß dessen Schneidelementen oder Messern jeweils ein Stück des Papierbandes von der gewünschten Länge zugeführt wird.The device described works in the following way: A continuous paper tape 20 is over a _> « Feeder roller 21 of the counter-cutting roller 12 is supplied. The paper tape 20 from the feed roller 21 The given feed speed is somewhat lower than the peripheral speed of the counter-cutting roller 12 and so on the rotational speed of the knife 2> roller matched that its cutting elements or knives each have a piece of the paper tape from the desired length is fed.
Das Papier ist durch über nicht dargestellte Bohrungen in den Außenflächen der Haltesegmente 14 i< > ausgeübten Unterdruck in Anlage an der Gegenschneidwalze 12 gehalten. Dabei entsteht zwischen dem Papier und der Gegenschneidwalze zunächst ein gewisser Schlupf, bis jeweils ein Stück des Bandes abgeschnitten ist welches sich dann mit der Umfangsgeschwindigkeit der Gegenschneidwalze weiterbewegt, so daß sich zwischen den einzelnen abgeschnittenen Stücken jeweils ein gewisser Abstand ergibt (F i g. 2).The paper is through bores, not shown, in the outer surfaces of the holding segments 14 i < > The negative pressure exerted is held in contact with the counter-cutting roller 12. This arises between the Paper and the counter-cutting roller initially have a certain amount of slippage, until each a piece of tape is cut off which then continues to move at the peripheral speed of the counter-cutting roller, see above that there is a certain distance between the individual cut pieces (FIG. 2).
Je nach der Dicke des zu schneidenden Papiers sind die Schneiden der Messer 5 auf einen Radius OA einzustellen, welcher zwar veränderlich, in jedem Falle jedoch etwas größer ist als der Abstand OB von der Achse der Messerwalze zur Umfangsfläche der Gegenschneidwalze. Dieser geringfügige Abstandsunterschied wird durch eine leichte Durchbiegung der Wellenzapfen 2 und 3 ausgeglichen.Depending on the thickness of the paper to be cut, the cutting edges of the knives 5 are to be set to a radius OA which, although variable, is in any case somewhat greater than the distance OB from the axis of the knife roller to the circumferential surface of the counter-cutting roller. This slight difference in distance is compensated for by a slight deflection of the shaft journals 2 and 3.
Sofern die Achsen der Messerwalze und der Gegenschneidwalze nicht genau parallel zueinander sind, können die Schneidunterlagen 18 derart um ihre Lagerzapfen 15 schwenken, daß ihre Außenflächen sich genau parallel zu den Schneiden der Messer 5 ausrichten. Auf diese Weise setzen dann die Messer 5 mit ihren Schneiden über die gesamte Länge derselben auf den Schneidunterlagen 18 auf, so daß die aufeinander folgenden Stücke des Papierbandes glatt und sicher abgeschnitten werden.Unless the axes of the knife roller and the counter-cutting roller are exactly parallel to each other are, the cutting pads 18 can pivot about their journals 15 so that their outer surfaces Align exactly parallel to the cutting edges of the knives 5. In this way the knives 5 with their cutting over the entire length of the same on the cutting pads 18 so that the successive pieces of paper tape can be cut off smoothly and safely.
Die Messerwalze und die Gegenschneidwalze drehen sich mit der gleichen Umfangsgeschwindigkeit, und die Abstände der Messer in Umfangsrichtung der Messerwalze sind gleich denen der Schneidunterlagen in Umfangsrichtung der Gegenschneidwalze.The knife roller and the counter-cutting roller rotate at the same peripheral speed, and the The distances between the knives in the circumferential direction of the knife roller are the same as those of the cutting pads in Circumferential direction of the counter-cutting roller.
