Schutzabdeckung Für den Schneidwalzenbereich von AktenvernichternProtective cover for the cutting roller area of document shredders
Die Neuerung bezieht sich auf eine Schutzabdeckung nach dem Oberbegriff des Schutzanspruchs 1.The innovation relates to a protective cover according to the generic term of claim 1.
Generell bekannt ist eine derartige Schutzabdeckung beispielsweise aus der DE-P5 32 11 ?31 des gleichenSuch a protective cover is generally known, for example from DE-P5 32 11 ?31 of the same
Anmelders, allerdings dort bei einem Aktenvernichter ohne Zuführtisch.applicant, but there with a document shredder without a feed table.
Die Aufgabe der vorIiey«if;de. Neuerung besteht deshalb auch darin, bei Aktenvernichtern mit Zuführtisch eineThe purpose of the present innovation is therefore to provide a gegenübet dem bekannten Stand der Technik derart modifizierte Schutzabdeckung vorzusehen, die bei Verstopfungen und dgl. insbesondere ein Eingreifen in den Schneidwerksraum von den Zuführtischseiten her bei laufenden Schneidwalzen unmöglich macht, bzw. letztere sofort stillsetzt, wenn es dennoch versucht wird.Compared to the known state of the art, a modified protective cover should be provided which, in the event of blockages and the like, makes it impossible to reach into the cutting unit chamber from the feed table sides when the cutting rollers are running, or immediately stops the latter if it is attempted anyway.
Gelöst wird diese Aufgabe durch die in den Schutzansprüchen niedergelegten baulichen Mittel und anordnungstechnischen Maßnahmen, die im folgenden anhand eines perspektivisch in der Zeichnung dargestellten Ausführungsbeispiels im Detail näher beschrieben sind.This object is achieved by the structural means and arrangement measures laid down in the protection claims, which are described in more detail below using an embodiment shown in perspective in the drawing.
ein mit Laufrädern 2a versehenes Untergestell 2 sowie einen Aufgabetisch 3 mit Zuführband 3a für das zu vernichtende Material. Die k.'.appenf örmige, auf der Geräteoberseite 1a schwenkbar 4b angelenkte Schutzabdeckung 4 für den Schneidwalzenbereich zeichnet sicha base frame 2 provided with wheels 2a and a feed table 3 with feed belt 3a for the material to be destroyed. The cap-shaped protective cover 4 for the cutting roller area, which is pivotably 4b hinged on the top of the device 1a, is characterized by neuerungsgemäß nun vor allem dadurch aus, daß dieAccording to the new regulations, the
·&Ggr; · &Ggr;
freie Vorderkante "K" der Klappe 4 zur Bildung eines schmalen Einführspaltes "Sp" in Richtung auf die Zuführtischoberflä'che 3b hin untergezogen ist wobei die D &igr; mens ion ierung so getroffen ist, daß der zwischen der freien Kante "K", der Abkantung 4a und der Zufuhr t&igr; schöberse11e 5b gebildete E infuhr spa 11 "Sp" für dos zu vernichtende Material in etwa der durchschnittlichen Höhe eines menschlichen Handrückens entspr icht.free front edge "K" of the flap 4 is pulled downwards in the direction of the feed table surface 3b to form a narrow feed gap "Sp", the dimensioning being such that the feed gap "Sp" formed between the free edge "K", the bevel 4a and the feed table 5b for the material to be destroyed corresponds approximately to the average height of the back of a human hand.
Versucht nun also jemand insbesondere von den Seitenbegrenzungen "S" des Aufgabetisches 3 her bei einer eventuellen Verstopfung in den Schneidwerksraum zu greifen, wird die Schutzabdeckung 4 zwangsläufig stets nach oben bewegt und schaltet den Schneidwalzenantrieb dabei automatisch ab.If someone tries to reach into the cutting chamber, particularly from the side limits "S" of the feed table 3, in the event of a blockage, the protective cover 4 is inevitably always moved upwards and automatically switches off the cutting roller drive.
Letztlich gehört es noch zur baulichen Ausgestaltung des in der Zeichnung dargestellten Ausführungsbei-Spieles, daß die Klappe 4 in ihrem vorderen Bereich eine zu den Geräteseitente ilen 1b weitestgehend bündig verlaufende Abkantung 4a aufweist.Finally, the structural design of the example shown in the drawing also includes that the flap 4 has a bevel 4a in its front area that is largely flush with the side parts 1b of the device.
