Description

Die Erfindung betrifft eine Messerwalze mit mindestens einem Folienmesser, das an einem mehrteiligen Walzenkörper befestigbar ist, der an seinem Umfang Saugöffnungen und mit diesen verbundene, in Längsrichtung verlaufende Saugkanäle aufweist.The invention relates to a knife roller with at least one foil knife, which can be fastened to a multi-part roller body which has suction openings on its circumference and suction channels connected to them and running in the longitudinal direction.

Eine Messerwalze der genannten Art ist z.B. aus der US-PS 4 537 588 bekannt. Sie dient bei der Herstellung von Fensterbriefumschlägen zum Ausschneiden des Fensters. Während der Briefumschlagrohling von der Messerwalze zu einer weiteren Bearbeitungsstation transportiert wird, muß die Messerwalze das durch den Fensterausschnitt entstandene Abfallstück zunächst noch eine gewisse Zeit lang festhalten und dann in einen Absaugtrichter abgeben. Hierzu weist die Messerwalze Saugöffnungen auf, die über einen Saugkanal mit Vakuum beaufschlagbar sind.A knife roller of the type mentioned is e.g. known from U.S. Patent 4,537,588. It is used in the production of window envelopes to cut out the window. While the envelope blank is being transported from the knife roller to another processing station, the knife roller must first hold the piece of waste created by the window cutout for a certain time and then discharge it into a suction funnel. For this purpose, the knife roller has suction openings which can be subjected to a vacuum via a suction channel.

Der Erfindung liegt die Aufgabe zugrunde, eine Messerwalze für die Briefumschlagherstellung und andere Anwendungsfälle so zu gestalten, daß sie möglichst vielseitig verwendbar und vor allem auch in der Lage ist, mehr als nur ein einziges Abfallstück sicher und zuverlässig zu entsorgen.The invention has for its object a knife roller to design for envelope production and other applications in such a way that it is as versatile as possible and, above all, able to safely and reliably dispose of more than just a single piece of waste.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß Saugöffnungen in mehreren Sauglochreihen sowie in Umfangsrichtung versetzt vorgesehen sind, daß jeweils ein Saugkanal jeder Sauglochreihe zugeordnet ist und daß mindestens ein Saugluftsteuerkanal und mindestens eine verstellbare Saugluftsteuerscheibe vorgesehen sind, mit deren Hilfe der Saugluftsteuerkanal wahlweise mit den verschiedenen Saugkanälen, Sauglochreihen und deren Saugöffnungen verbindbar ist.To achieve this object, the invention provides that suction openings are provided in several rows of suction holes and offset in the circumferential direction, that one suction channel is assigned to each row of suction holes and that at least one suction air control channel and at least one adjustable suction air control disk are provided, with the aid of which the suction air control channel can optionally be used with the various suction channels, rows of suction holes and their suction openings can be connected.

Die besagten Maßnahmen gestatten es, z.B. bei Verwendung von zwölf Sauglochreihen und entsprechend vielen Saugkanälen, von drei Saugluftsteuerkanälen und von zwei stirnseitig angeordneten Saugluftsteuerscheiben drei verschiedene Abfallstücke sicher und zuverlässig zu entsorgen, die über den Umfang der Messerwalze verteilt sind und wegtransportiert sowie im richtigen Augenblick abgegeben werden müssen. Vorteilhaft ist es dabei ferner, daß mit Hilfe von Saugöffnungen in dem bzw. den Folienmessern jeweils nur die benötigten Saugöffnungen der verschiedenen Sauglochreihen mit Vakuum beaufschlagt werden, während die anderen Saugöffnungen abgedeckt sind.The said measures allow, e.g. When using twelve rows of suction holes and a corresponding number of suction channels, three suction air control channels and two suction air control disks on the front, three different waste pieces can be safely and reliably disposed of, which are distributed over the circumference of the knife roller and have to be transported away and dispensed at the right moment. It is furthermore advantageous that with the aid of suction openings in the film knife (s) only the required suction openings of the various rows of suction holes are subjected to vacuum, while the other suction openings are covered.

Eine Saugluftsteuerung in der beschriebenen Form läßt sich durchführen unabhängig davon, ob die Folienmesser mit Hilfe von Magnetleisten oder mit Hilfe einer mechanischen Spann- und Befestigungsvorrichtung am mehrteiligen Walzenkörper gehalten werden.Suction control in the form described can be carried out regardless of whether the foil knives are held on the multi-part roller body with the aid of magnetic strips or with the aid of a mechanical tensioning and fastening device.

Die Schneidstation 1a gemäß Fig. 2 dient zur Bearbeitung von Briefumschlagrohlingen 4a, wobei eine Schneidleiste 3a als Gegenwerkzeug für die Messerwalze 2 vorgesehen ist. Auch hier ist die Schneidleiste 3a zusammen mit ihrem Träger 5 in Richtung der Pfeile auf die Messerwalze 2 hin und von dieser weg verstellbar. Zur Übernahme und zum Transport des Briefumschlagrohlings 4a weist die Messerwalze 2 eine Saugleiste 6 (Fig. 3) mit Saugöffnungen 7 auf, wobei die Saugleiste 6 in ihrer Phasenlage zur zu- und abführenden Walze 8, 9 winkelmäßig fest angeordnet ist.The cutting station 1a according to FIG. 2 is used for processing envelope blanks 4a, a cutting bar 3a being provided as a counter-tool for the knife roller 2. Here, too, the cutting bar 3a can be adjusted together with its carrier 5 in the direction of the arrows towards the knife roller 2 and away from it. To take over and transport the envelope blank 4a, the knife roller 2 has a suction bar 6 (FIG. 3) with suction openings 7, the suction bar 6 being angularly arranged in its phase position relative to the feed and discharge roller 8, 9.

Der von der Saugleiste 6 ergriffene Briefumschlagrohling 4a wird längs einer Kreisbahn unter dem Gegenwerkzeug bzw. der Schneidleiste 3a hindurchgeführt, wobei ein Fenster ausgeschnitten wird. Der Fensterausschnitt bzw. das Abfallstück wird mittels Sauglauft innerhalb der Fenstermesserperipherie gehalten und schließlich in einen Absaugtrichter 10 abgegeben, während der Briefumschlagrohling 4a von der abführenden Walze 9 weiter transportiert wird.The envelope blank 4a gripped by the suction bar 6 is passed along a circular path under the counter tool or the cutting bar 3a, a window being cut out. The window cutout or the waste piece is held within the window knife periphery by means of suction and finally discharged into a suction funnel 10, while the envelope blank 4a is transported further by the discharging roller 9.
