Feinschnitt-Schneidwerk für Aktenvernichter Fine-cut cutter for document shredders
Die Erfindung betrifft ein Feinschnitt-Schneidwerk für einen Aktenvernichter, insbesondere für einen Büro-Aktenvernichter, insbesondere für die Verwendung als Dokumentenvernichter für Akten und Dokumente aus Papier und dergleichen Materialien, die in einer hohen Sicherheitsstufe zerkleinert werden müssen.The invention relates to a fine-cutting cutter for a document shredder, in particular for an office document shredder, in particular for use as a document shredder for files and documents made of paper and similar materials which have to be shredded in a high security level.
Bekannte Schneidwerke für Aktenvernichter, die besagte Akten und Dokumente in hohen Sicherheitsstufen vernichten (zerkleinern), sind in der Regel mit einem Partikelschnitt-Schneidwerk ausgestattet. Diese Schneidwerke sind so aufgebaut, dass die Schneidscheiben der Schneidwalzen in ihrer Umfangsfläche (Mantelfläche) jeweils mehrere, radial gerichtete Aussparungen derart aufweisen, dass Schneidlücken entstehen. Zwei mit ihrer jeweiligen Längsachse parallel zueinander angeordnete und mit ihren jeweiligen Schneidscheiben auf Lücke stehende, teilweise ineinander greifende, also kämmende Schneidwalzen bilden einKnown cutting units for document shredders, which destroy (shred) said files and documents in high security levels, are usually equipped with a particle cutting unit. These cutting units are constructed in such a way that the cutting disks of the cutting rollers each have a plurality of radially directed cutouts in their circumferential surface (lateral surface) in such a way that cutting gaps arise. Two cutting rollers, which are arranged parallel to one another with their respective longitudinal axes and have gaps with their respective cutting disks, partially intermeshing, that is to say meshing, form one
BESTATIGUNGSKOPIE Schneidwerk. Aufgrund dessen, dass an der Umfangsfläche jeder Schneidscheibe nur ein Bereich von 360 Grad zur Verfügung steht, kann mit derart konzipierten Aktenvernichtern maximal eine minimale Partikelgröße erzielt werden, die der Sicherheitsstufe 5 entspricht.BESTATIGUNGSKOPIE Cutting. Due to the fact that only an area of 360 degrees is available on the circumferential surface of each cutting disc, a maximum particle size corresponding to security level 5 can be achieved with document shredders designed in this way.
Um eine Partikelschnittgröße zu erhalten, die kleiner ist als die vorgenannten Angaben, sind am Markt des Weiteren Lösungen bekannt, bei denen insbesondere mehrere Blatt des zu vernichtenden Materials einem Fräser zugeführt und zerkleinert werden.In order to obtain a particle cut size that is smaller than the aforementioned information, solutions are also known on the market in which, in particular, several sheets of the material to be shredded are fed to a milling cutter and comminuted.
Nachteilig am bekannten Stand der Technik ist, dass bei der erstgenannten Methodik selbst ein erhöhter technischer Aufwand nicht zu kleineren Partikeln führt. Auch wenn die Partikelgröße in der Breite durch schmälere Schneidscheiben und Lücken verkleinert werden kann, ist mit bekannter Schneidengeometrie eine Verkürzung der Partikellänge bisher nicht erzielbar. Bei der zweitgenannten Methodik, dem Fräsen, erhält man zwar kleinere Partikelgrößen, nahezu staubartige Partikel, jedoch ist der hohe technische Aufwand ein wesentlicher Nachteil. Zudem kann nicht vermieden werden das von den zerkleinerten Dokumenten Reststücke unzerkleinert übrig bleiben, die nicht der Sicherheitsstufe 5 entsprechen.A disadvantage of the known prior art is that even an increased technical outlay does not lead to smaller particles in the first-mentioned methodology. Even if the particle size can be reduced in width by narrower cutting disks and gaps, it has not been possible to shorten the particle length with known cutting edge geometry. With the second method, milling, one obtains smaller particle sizes, almost dust-like particles, but the high technical effort is a major disadvantage. In addition, it cannot be avoided that remnants of the shredded documents remain uncrushed that do not correspond to security level 5.
Daher besteht die Aufgabe der Erfindung darin, ein Schneidwerk für Aktenvernichter zu schaffen, mit dem ein Feinschnitt realisierbar ist, also eine Partikelgröße besser als die Sicherheitsstufe 5 erreicht werden kann, wobei der fertigungstechnische Aufwand für dieses Schneidwerk zudem gering zu halten ist.Therefore, the object of the invention is to provide a cutter for document shredders with which a fine cut is feasible, that is, a particle size better than security level 5 can be achieved, the manufacturing outlay for this cutting device also being kept low.

Die Schneidwalzen eines jeden der beiden Schneidwerke 30, 40 sind in an sich bekannter Art angeordnet. Dem ersten Schneidwerk 30 ist, in im Wesentlichen vertikaler Ausrichtung, ein zweites Schneidwerk 40 nachgeordnet; hier im Speziellen unterhalb vom ersten, so dass das durch den ersten Schnitt erzeugte Schnittgut, die Partikel, unmittelbar folgend im zweiten Schneidwerk ein zweites Mal quer und zudem möglichst häufig geschnitten werden können.BESTATIGUNGSKOPIE the cutting rollers 41 and 42 of the second cutting unit 40 of the new fine-cutting unit 1 are shown. The cutting rollers of each of the two cutting units 30, 40 are arranged in a manner known per se. A second cutting device 40 is arranged downstream of the first cutting device 30 in a substantially vertical orientation; here in particular below the first, so that the clippings generated by the first cut, the particles, can be cut transversely and immediately as often as possible immediately afterwards in the second cutting unit.
Das unter dem ersten Schneidwerk 30 angeordnete zweite Schneidwerk 40 ist derart vorgesehen, dass die gedachte, quer verlaufende Verbindungslinie zwischen den Längsachsen der jeweiligen Schneidwalzen-Paare 31 , 32 und 41 , 42 im Wesentlichen zueinander parallel liegen.
