Description

Die Erfindung bezieht sich auf ein Verfahren nach dem Oberbegriff des Hauptanspruchs sowie auf eine Vorrich­ tung bzw. Elemente und deren Anordnung zur Verfahrens­ durchführung. The invention relates to a method according to the Preamble of the main claim as well as a device device or elements and their arrangement for the process execution.  

Bei bekannten Aktenvernichtern der hier nach dem An­ spruchsoberbegriff zur Rede stehenden Art ist es bis­ lang üblich, die Abtastung des Füllungsgrades beim in das Untergestell eingehängten Abfallsammelsackes mecha­ nisch, und zwar mittels einer an der Schneidwerksun­ terseite angeordneten Pendelklappe vorzunehmen, die mit dem Schneidwalzenantrieb schaltungsmäßig derart gekop­ pelt ist, daß bei einer voreingestellten Klappenaus­ lenkung, bedingt durch den sich seitlich ausbreitenden Schnittgutkegel, eine selbsttätige Antriebsabschaltung erfolgt, bevor dieser Kegel in den Schnittgutaustritts­ spalt hineinreicht. Mehrfaches Rütteln am Abfallsammel­ sack oder Abflachen der Kegelspitze von Hand um einen größeren Füllungsgrad zu erzielen kann in der Praxis aber dazu führen, daß sich geschnittenes Material auch hinter der Pendelklappe anstaut und deren für die Antriebsab­ schaltung notwendige Auslenkung blockiert, so daß sich der gesamte Schnittgutaustrittsschacht vollsetzen und das Schneidwerk vor allem bei kurzzeitigem Rückwärts­ lauf schwer beschädigen kann.In known document shredders here after the it is up to long usual, the sampling of the degree of filling when in the base of the waste collection bag mecha niche, by means of one at the cutting unit underside arranged swing flap to make with in terms of circuitry, the cutting roller drive is coupled in this way pelt is that at a preset flap steering, due to the laterally spreading Clippings cone, an automatic drive shutdown occurs before this cone enters the clippings gap extends into it. Multiple shaking on the waste collection sack or flatten the cone tip by hand around you In practice, however, it is possible to achieve a greater degree of filling cause material to be cut behind of the pendulum flap and theirs for the drives circuit necessary deflection blocked, so that complete the entire clippings outlet and the cutting unit, especially when reversing briefly can seriously damage the barrel.

Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, Mittel und Wege zu finden, die die zuletzt ge­ nannten Nachteile und damit verbundenen Gefahren trotz manueller Eingriffe in die automatische "Sack-voll"- Anzeige gar nicht erst entstehen lassen. The object of the present invention is therefore in finding ways and means that the last ge named disadvantages and associated dangers despite manual intervention in the automatic "bag full" - Don't let the ad appear.  

Gelöst wird diese Aufgabe durch die in den Patentan­ sprüchen angegebenen Verfahrensmerkmale und baulichen sowie anordnungstechnischen Maßnahmen.This problem is solved by the in the patent procedural features and structural characteristics as well as arrangement-related measures.

Die Zeichnung zeigt weitestgehend schematisch die er­ finderische Lösung an einem Aktenvernichter in längs­ geschnittener Seitenansicht.The drawing largely shows the he resourceful solution on a shredder in lengthways cut side view.

Das neue Verfahren der "Sack-voll"-Anzeige mit gleich­ zeitiger Antriebsabschaltung der Schneidwalzen 3 funk­ tioniert gemäß Darstellung in der Zeichnungsfigur nun wie folgt:The new process of the "bag full" display with simultaneous drive shutdown of the cutting rollers 3 now functions as shown in the drawing figure as follows:

  • a) Sobald der sich zur Schneidwerksunterseite 2 hin aufbauende Schnittgutkegel 7 bzw. eine seiner Flanken 7 a in einen vorbestimmten Ab­ stand "A" zum Sensor 8 a des Näherungsschal­ ters 8 gelangt, wird dieser bedämpft und der Antrieb der Schneidwalzen 3 damit abgeschal­ tet.a) As soon as the cutting material cone 7 building up towards the cutting unit underside 2 or one of its flanks 7 a reaches the sensor 8 a of the proximity switch 8 in a predetermined position "A" , this is damped and the drive of the cutting rollers 3 is thus switched off.
  • b) Ein manuelles Glätten der im Querschnitt ke­ gelförmigen "Schnittgutleiste" 7 führt zwar nach wie vor zu einem Wiederanlauf des Schneid­ werks, jedoch nur solange bis sich auf der neuen Ebene I oder II im Abfallsammelsack 5 wieder ein Kegel 7 aufbaut und erneut ab­ schaltet. Der Kegel 7 kann also niemals mehr in den Austrittsspalt "Sp" hineinwachsen und die eingangs erwähnten Störungen bzw. Be­ schädigungen herbeiführen.b) A manual smoothing of the cross-sectionally ke-shaped "clippings strip" 7 still leads to a restart of the cutting unit, but only until a cone 7 builds up on the new level I or II in the waste collection bag 5 and switches off again . The cone 7 can never grow into the exit gap "Sp" and cause the disturbances or loading mentioned above.

Vorrichtungsgemäß zeichnet sich die Erfindung dabei aus durch einen an der Unterseite 2 des Schneidwerksauf­ satzes 1 angeordneten Infrarotschalter 8 mit zum Schneid­ spalt "Sp" zwischen Schneidwalzen 3 und Abstreifern 4 hin gerichtetem Sensor 8 a, wobei dieser Schalter 8 seitlich zum Schneidspalt "Sp" versetzt und aus der Horizontalen zum Abfallsammelsack 5 hin geneigt in einer Halterung 9 an der Schneidwerksunterseite 2 sitzt. Die Neigung des Schalters 8 ist dabei derart zu wählen, daß seine Bedämpfungsfläche d.h. die Stirnfläche des Sen­ sors 8 a des Schalters 8 in etwa parallel zur der sich unterhalb des Schneidspalts "Sp" aufbauenden Flanke 7 a der im Querschnitt kegelförmigen Schnittgutleiste 7 verläuft.Device according to the invention is distinguished here by a arranged on the bottom 2 of the Schneidwerksauf set 1 Infrared switch 8 with a gap for cutting "Sp" between the cutting rollers 3 and scrapers 4 out directional sensor 8 a, which switch laterally offset 8 for cutting gap "Sp" and is inclined from the horizontal towards the waste collection bag 5 in a holder 9 on the underside 2 of the cutting unit. The inclination of the switch 8 is to be selected such that its damping surface, ie the end face of the sensor 8 a of the switch 8 , runs approximately parallel to the edge 7 a of the conical cross section of the clippings strip 7 which is below the cutting gap “Sp” .
