Description
Die Erfindung bezieht sich auf ein Verfahren nach dem Oberbegriff des Hauptanspruchs sowie auf eine Vorrichtung bzw. Elemente und deren Anordnung zur Verfahrensdurchführung.The invention relates to a method according to the preamble of the main claim and one Device or elements and their arrangement for Procedure execution.
Bei bekannten Aktenvernichtern der hier zur Rede stehenden Art ist es, wie z.B. die DE-PS 33 12 991 zeigt, bislang üblich, die Abtastung des Füllungs grades beim in das Untergestell eingehängten Abfall sammelsackes mechanisch mittels einer an der Schneid werksunterseite angeordneten Pendelklappe vorzunehmen, die mit dem Schneidwalzenantrieb schaltungsmäßig derartig gekoppelt ist, daß bei einer voreingestellten Klappenauslenkung, bedingt durch die sich seitlich ausbreitende Schnittgutschüttung, eine selbsttätige Antriebsabschaltung erfolgt, bevor die Spitze dieser Schüttung in den Schnittgutaustrittsspalt hineinreicht. Mehrfaches Rütteln am Abfallsammelsack oder Ab flachen dieser Spitze von Hand, um einen größeren Füllungsgrad zu erzielen, hat bislang in der Praxis aber oft dazu geführt, daß sich geschnittenes Material auch hinter der Pendelklappe anstaut und deren für die Antriebsabschaltung notwendige Auslenkung blockiert, so daß sich der gesamte Schnittgutaustritts schacht vollsetzen und das Schneidwerk vor allem bei kurzzeitigem Rückwärtslauf schwer beschädigt werden konnte.Known document shredders here it is standing type, e.g. DE-PS 33 12 991 shows, so far usual, the scanning of the filling degrees with the waste suspended in the base collection bag mechanically by means of a cutting to carry out the pendulum flap arranged at the factory, the circuit with the cutting roller drive is coupled such that at a preset Flap deflection caused by the side spreading clippings, an automatic Drive shutdown occurs before the top of this Fill into the clippings outlet gap. Repeated shaking on the waste collection bag or Ab flatten this tip by hand to make a larger one Achieving a degree of filling has so far been in practice but often resulted in cut material also accumulates behind the pendulum flap and its deflection necessary for the drive switch-off blocked so that the entire clippings exit Fill the shaft and above all the cutting unit badly damaged during a short reverse run could be.
Die Aufgabe der vorliegenden Erfindung besteht deshalb auch darin, ein Verfahren und eine bauliche Anordnung zu schaffen, die nicht manipulierbar ist und den Walzenantrieb stets sicher abschaltet, wenn eine vorbestimmte Höhe der Schnittgutschüttung erreicht worden ist. The object of the present invention is therefore also in a process and a structural Creating arrangement that cannot be manipulated and always safely switches off the roller drive, if a predetermined height of the clippings has been achieved.
Gelöst wird diese Aufgabe durch die in den Patent ansprüchen angegebenen Verfahrensmerkmale und bau lichen sowie anordnungstechnischen Maßnahmen.This task is solved by the in the patent Process features and construction specified claims and technical measures.
Die Zeichnung zeigt weitestgehend schematisch die neue Lösung an einem Aktenvernichter in längs geschnittener Seitenansicht.The drawing shows the largely schematically new solution on a shredder in longitudinal cut side view.
Das neue Verfahren der "Sack-voll"-Anzeige mit gleichzeitiger Antriebsabschaltung der Schneidwalzen 3 funktioniert gemäß Darstellung in der Zeichnungs figur nun wie folgt:The new process of the "bag full" display with simultaneous drive shutdown of the cutting rollers 3 now works as follows in the drawing:
- a) Sobald die sich zur Schneidwerksunter seite 2 hin aufbauende Schnittgutschüttung 7 bzw. eine ihrer Flanken 7 a in einen vorbestimmten Abstand "A" zum Sensor 8 a des Näherungsschalters 8 gelangt, wird dieser bedämpft und der Antrieb der Schneid walzen 3 damit abgeschaltet.a) As soon as the cutting bed 7 building up to the cutting unit lower side 2 or one of its flanks 7 a reaches the sensor 8 a of the proximity switch 8 at a predetermined distance "A" , this is damped and the drive of the cutting rollers 3 thus switched off.
- b) Ein manuelles Glätten der im Querschnitt etwa dreieckförmigen Schüttung 7 führt zwar nach wie vor zu einem Wiederanlauf des Schneidwerks, jedoch nur solange, bis sich auf der neuen Ebene I oder II im Abfallsammelsack 5 wieder eine Schüttung 7 aufbaut und den Antrieb erneut abschaltet. Die Schüttung 7 kann also niemals mehr in den Austrittsspalt "Sp" hineinwachsen und die eingangs erwähnten Störungen bzw. Beschädigungen herbeiführen.b) Manual smoothing of the bed 7 , which is approximately triangular in cross section, still leads to a restart of the cutting unit, but only until a bed 7 is built up again on the new level I or II in the waste collection bag 5 and the drive is switched off again. The bed 7 can therefore never again grow into the outlet gap "Sp" and cause the disturbances or damage mentioned at the outset.
Vorrichtungsgemäß zeichnet sich die Erfindung dabei aus durch einen an der Unterseite 2 des Schneid werksaufsatzes 1 angeordneten Infrarotschalter 8, der seitlich zum Schneidspalt (Sp) versetzt und aus der Horizontalen zum Abfallsammelsack 5 hin geneigt in einer Halterung 9 o.ä. an der Schneid werksunterseite 2 angeordnet ist. Die Neigung des Schalters 8 ist dabei derart zu wählen, daß die Bedämpfungsfläche, d.h. die Stirnfläche des Sensors 8 a des Schalters 8 annähernd parallel zu der sich unterhalb des Schneidspaltes Sp aufbauenden Flanke 7 a der im Querschnitt etwa dreieckförmigen Schnitt gutschüttung 7 verläuft.According to the device, the invention is characterized by an infrared switch 8 arranged on the underside 2 of the cutting attachment 1 , which is laterally offset from the cutting gap (Sp) and inclined from the horizontal towards the waste collection bag 5 in a holder 9 or the like. is arranged on the cutting unit underside 2 . The inclination of the switch 8 is to be selected such that the damping surface, ie the end face of the sensor 8 a of the switch 8, runs approximately parallel to the flank 7 a, which is built up below the cutting gap Sp and is approximately triangular in cross section 7 .
