Description
Die Erfindung, wie sie im Anspruch 1 definiert ist, bezieht sich auf einen Aktenvernichter, insbesondere einen sogenannten Büroaktenvernichter, mit einem Aufsatz zur Aufnahme und Zuführung von Schriftgut, insbesondere von Knüllmaterial, z.B. in Papierkörben und dergleichen Behältnissen gesammeltes Knüllpapier.The invention as defined in
In der Praxis sind Aktenvernichter bekannt, die auch für das Schreddern von sogenanntem Knüllmaterial einsetzbar sind. Zusätzlich zu einem Zuführspalt für blattartiges Material besitzen diese Aktenvernichter einen von oben her auf dessen Gehäuseoberteil aufgesetzten Materialsammelbehälter für die Aufnahme von Knüllmaterial. Zudem weisen diese Aktenvernichter in der Regel einen schrankartigen oder schrankähnlichen Unterbau auf, auf den das Gehäuseoberteil mitsamt dem aufgesetzten Materialsammelbehälter angeordnet ist.Shredders are known in practice, which can also be used for shredding so-called crumb material. In addition to a feed gap for sheet-like material, these document shredders have a material collecting container mounted on top of the housing upper part for receiving crumb material. In addition, these document shredders usually have a cabinet-like or cabinet-like base on which the upper housing part is arranged together with the attached material collection container.
Diese Aktenvernichter, die in Fachkreisen üblicherweise als Etagen- oder Großaktenvernichter bezeichnet werden, finden auf Büroetagen bzw. Großraumbüros Anwendung, also dort, wo ein den Gerätekosten entsprechendes großes Volumen an Knüllmaterial anfällt.
Mitarbeiter kleinerer Büroeinheiten müssen das bei ihnen anfallende Knüllpapier sammeln und von Zeit zu Zeit zu einem Sammelpunkt bringen, wodurch mitunter nicht unerhebliche Büronebenzeiten anfallen sowie zusätzlicher Platz für die Sammelbehälter benötigt wird.These document shredders, which are usually referred to in professional circles as a floor or large-scale shredder, find application on office floors or open-plan offices, ie where a large volume of crumb material corresponding to the device costs.
Employees of smaller office units need to collect their crumpled paper and bring it from time to time to a collection point, which sometimes incurs insignificant bureau life and additional space is needed for the collection container.
Ferner sind Aktenvernichter dieser Art aus der DE-A-2 335 344 und der GB-A-2 095 579 bekannt, welche wahlweise mit einem Aufsatz zur Aufnahme und Zuführung von insbesondere geknülltem Schriftgut, wie es in Papierkörben anfällt, betrieben werden kann.Furthermore, document shredders of this type are known from DE-A-2 335 344 and GB-A-2 095 579, which can optionally be operated with an attachment for receiving and feeding in particular wrinkled documents, as obtained in wastebaskets.
Die Aufgabe der Erfindung besteht nun darin, einen Aktenvernichter, insbesondere einen sogenannten Büroaktenvernichter derart zu gestalten, dass unter Einhaltung der für Büroaktenvernichter geltenden Sicherheitsvorschriften, ein zügiges Schreddern des in den Aufsatz eingefüllten, dem Schneidwerk zugeführten Knüllmaterials gesichert ist, insbesondere wesentliche Betriebsunterbrechungen durch angestautes Material vermieden werden.The object of the invention is therefore to design a document shredder, in particular a so-called office shredder so that, while maintaining the existing office shredder security regulations, a speedy shredding of the filled into the essay, the cutting unit supplied crumb is secured, in particular essential business interruptions by accumulated material be avoided.
Die Aufgabe löst ein Aktenvernichter mit einem Aufsatz zur Aufnahme und Zuführung von Schriftgut, insbesondere für sogenanntes Knüllmaterial, der gemäß den Merkmalen des Patentanspruches 1 ausgebildet ist; die Patentansprüche 2 bis 10 offenbaren Weiterbildungen und vorteilhaften Ausführungsvarianten des Erfindungsgegenstandes.The object is achieved by a document shredder with an attachment for receiving and feeding documents, in particular for so-called crumpling material, according to the features of
Die Erfindung geht aus von einem Aktenvernichter mit einem Aufsatz zur Aufnahme und Zuführung von Schriftgut, wobei der Aktenvernichter ein Gehäuse, welches aus einem Gehäuseunterteil und einem Gehäuseoberteil besteht, aufweist sowie ein im oberen Bereich des Gehäuses angeordnetes Schneidwerk, mit Schneidwalzen und Abstreifern nebst einem zugeordneten Antriebsaggregat sowie Schalt- und Steuerungsmittel, und wobei oberhalb des Schneidwerkes im vorderen Bereich des Gehäuseoberteiles ein Zuführspalt vorgesehen ist und das Gehäuseunterteil Mittel zum Sammeln des zerkleinerten Materials enthält oder aufnimmt. Neu an diesem Aktenvernichter mit wahlweise aufsetzbaren Aufsatz ist, dass oberhalb des Schneidwerkes die obere Fläche des Gehäuseoberteiles ein wahlweise herausnehmbares und wieder einsetzbares Gehäuseabschnittsteil besitzt, und dass vom Schneidwerk ausgehend bis zur geöffneten oberen Fläche hinreichend ein Zuführschacht vorgesehen ist, und dass der geöffnete Bereich der oberen Fläche von einem auf das Gehäuseoberteil aufgesetzten Aufsatz überdeckt wird, dessen untere Fläche im wesentlichen und insbesondere im besagten Überdeckungsbereich geöffnet ist, wobei der Innenraum des Aufsatzes und der Zuführschacht einen gemeinsamen Aufnahmeraum bilden, und dass im Aufsatz integriert ein nicht rotierender Materialschieber angeordnet ist.The invention relates to a document shredder with an attachment for receiving and feeding documents, the shredder a housing, which consists of a lower housing part and a housing upper part, and a arranged in the upper region of the housing cutter, with cutting rollers and scrapers together with an associated Drive unit and switching and control means, and wherein above the cutting mechanism in the front region of the upper housing part, a feed gap is provided and the lower housing part contains or receives means for collecting the comminuted material. New to this document shredder with optional attachable attachment is that above the cutting unit, the upper surface of the housing upper part has an optionally removable and reusable housing portion part, and that starting from the cutting mechanism to the open upper surface sufficiently a feed chute is provided, and that the open area of the top surface is covered by an attached to the upper housing part essay, the lower surface is opened substantially and in particular in said overlay region, wherein the interior of the article and the feed chute form a common receiving space, and that integrated in the essay a non-rotating material slide is arranged.
Die Vorteile der Erfindung liegen vor allem darin, dass unter Einhaltung der Sicherheitsvorschriften ein zügiges Schreddern des in den Aufsatz eingefüllten, dem Schneidwerk zugeführten Knüllmaterials ohne wesentliche Betriebsunterbrechungen gesichert ist.The advantages of the invention are, above all, that while adhering to the safety regulations, rapid shredding of the crimped material introduced into the attachment and fed to the cutting mechanism is secured without significant interruptions in operation.
Der neue Aufsatz für einen Aktenvernichter, der besagtes, sogenanntes Knüllpapier aufnimmt und dem Schneidwerk zuführt, ist dabei derart gestaltet, dass einerseits ein unbeabsichtigtes Eingreifen mit der Hand, durch den Aufnahmeraum des Aufsatzes hindurch, in das laufende Schneidwerk hinein nicht erfolgen kann, andererseits jedoch im Aufnahmeraum des Aufsatzes und/oder im dem Schneidwerk vorgelagerten Zuführschacht verklemmtes, momentan sich nicht bewegendes Knüllmaterial für das weitere Nachrutschen zum Schneidwerk hin aufgelockert wird und gleichzeitig bzw. unmittelbar anschließend - oder vorausgehend - in Richtung zum Schneidwerk hin schiebbar ist, und zwar bei laufendem Schneidwerk. Auch dies ist ein wesentlicher Vorteil des Erfindungsgegenstandes gegenüber bekannten Lösungen. Durch eine vom Antrieb des Schneidwerkes getrennte Betätigung das Materialschiebers ist einerseits ein fortlaufender Wechsel zwischen Auflockern und Andrücken des Abfallmaterials möglich und zudem ermöglicht der neue Aufsatz mit Materialschieber erstmals ein dosiertes Anpressen des Knüllpapiers in Richtung zum Schneidwerk. Die durchsichtige Frontfläche des Aufsatzes ermöglicht zusammen mit dem neuartigen Materialschieber ein effektives Bedienen des Aktenvernichters.The new essay for a shredder, which receives said so-called crumpled paper and feeds the cutting unit, is designed such that on the one hand inadvertent intervention by hand, through the receiving space of the essay through, can not be done in the current cutting mechanism, on the other hand in the receiving space of the essay and / or in the cutting unit upstream feed chute jammed, currently not moving crumb material is loosened for further slipping towards the cutting and at the same time or immediately afterwards - or in advance - towards the cutting unit pushed towards, while running cutting. This too is one significant advantage of the subject invention over known solutions. By a separate from the drive of the cutting operation of the material slide on the one hand, a continuous change between loosening and pressing the waste material possible and also allows the new essay with material shifter for the first time a metered pressing the crumpled paper toward the cutting unit. The transparent front surface of the attachment, together with the new material slide, enables effective operation of the shredder.
In Weiterbildung der Erfindung ist vorgesehen, dass der Materialschieber aus zwei seitlich im Aufsatz angeordneten Schenkeln besteht, die zur Frontfläche hin durch eine Leiste, die im wesentlichen parallel zu den Drehachsen der Schneidwalzen ausgerichtet angeordnet ist, miteinander verbunden sind.In development of the invention it is provided that the material slide consists of two laterally arranged in the essay legs, which are connected to the front surface by a bar, which is arranged aligned substantially parallel to the axes of rotation of the cutting rollers with each other.
Gemäß einer Ausführung ist der Materialschieber translatorisch verschiebbar gelagert. Nach einer anderen Ausführung kann der Materialschieber jedoch schwenkbar gelagert sein. Welche Ausführung gewählt wird hängt vom hauptsächlich vorgesehenen Einsatz ab; bei großvolumigen Knüllpapier wird eher der schwenkbare Materialschieber eingesetzt werden, letztendlich ist es jedoch eine Entscheidung des Anwenders.According to one embodiment, the material slider is mounted translationally displaceable. According to another embodiment, however, the material slider may be pivotally mounted. Which version is chosen depends on the mainly intended use; with large-volume crumpled paper, the pivoting material slider is more likely to be used, but ultimately it is a decision of the user.
Nach weiteren Ausführungsbeispielen ist vorgesehen, dass die Schenkel des Materialschiebers in bzw. an den Seitenflächen des Aufsatzes verschiebbar geführt angeordnet oder die Schenkel mit ihren anderen Enden jeweils an einem Drehlager befestigt sind, wobei letzterem eine Betätigungswelle zugeordnet ist, die vorzugsweise aus der Seitenfläche des Aufsatzes herausragt und im Wesentlichen von dort betätigbar ist.
Der Materialschieber wird bevorzugt als einteiliger Bügel gefertigt.According to further embodiments, it is provided that the legs of the material slide arranged displaceably guided in or on the side surfaces of the attachment or the legs with their other Ends are each attached to a rotary bearing, wherein the latter is associated with an actuating shaft, which preferably protrudes from the side surface of the attachment and can be actuated substantially from there.
The material slider is preferably made as a one-piece bracket.
Nach einer anderen speziellen Weiterbildung ist vorgesehen, dass der im Gehäuseoberteil vorgesehene Zuführschacht von seitlichen Wänden, einer vorderen Begrenzungsfläche und einer nach vorn zum Schneidwerk hin geneigten hinteren Begrenzungsfläche gebildet ist, wobei die hintere Begrenzungsfläche mit geringem Abstand vor der äußeren Umfangslinie der hinteren Schneidwalze endet und die gedachte Verlängerung der im Wesentlichen ebenen hinteren Begrenzungsfläche die hintere Schneidwalze an deren äußerer Umfangslinie im Wesentlichen tangiert und, wobei die hintere Begrenzungsfläche zugleich der untere Anschlag für die Bewegung des Materialschiebers ist.
Zudem ist im Speziellen noch vorgesehen, dass die gedachte Verlängerung der Bewegungsbahn, auf der das Mittelteil des verschiebbaren Materialschiebers, insbesondere die Leiste, bewegt wird, im Wesentlichen durch den Überlappungsbereich der Schneidwalzen verläuft.According to another specific development, it is provided that the provided in the upper housing part feed chute is formed by side walls, a front boundary surface and a front towards the cutting unit inclined rear boundary surface, the rear boundary surface ends at a small distance in front of the outer peripheral line of the rear cutting roller and the imaginary extension of the substantially planar rear boundary surface substantially tangentially engages the rear cutting roller on its outer circumferential line, and the rear boundary surface is at the same time the lower stop for the movement of the material slider.
In addition, it is also specifically provided that the imaginary extension of the movement path on which the middle part of the displaceable material slider, in particular the strip, is moved, extends essentially through the overlapping region of the cutting rollers.
Eine andere Ausführungsvariante sieht vor, dass die Begrenzungsfläche des Zuführspaltes und die vordere Begrenzungsfläche des Zuführschachtes ein gemeinsames Bauteil sind.Another embodiment provides that the boundary surface of the feed gap and the front boundary surface of the feed chute are a common component.

Die Darstellungen in den Figuren 1 und 2 sind zur besseren Veranschaulichung der Erfindung nur zum Teil geschnitten dargestellt.
Die Figur 1 zeigt einen Teilbereich eines Aktenvernichters 1. In dem Gehäuseunterteil 2 mit Fronttür 3 ist in dessen oberen Bereich ein Schneidwerk 6 mit Schneidwalzen 6a und 6b sowie zugeordneten Abstreifern 6c angeordnet, wobei dem Schneidwerk 6 ein Antriebsaggregat 5 zugeordnet ist. Das Schneidwerk 6 wird hier von einem von oben her auf das Gehäuseunterteil 2 aufgesetztem Gehäuseoberteil 4 im wesentlichen abgedeckt. Im vorderen Bereich 4a des Gehäuseoberteiles 4 ist ein Zuführspalt 7 mit Begrenzungsflächen 7a und 7b angeordnet, durch welchen blattartiges Material zum Zerkleinern dem Schneidwerk zugeführt werden kann.
Oberhalb des Schneidwerkes 6 ist bis zur oberen Fläche 4b des Gehäuseoberteiles 4 hin ein Zuführschacht 8 vorgesehen, der nach vorn durch eine vordere Begrenzungsfläche 9 und nach hinten durch eine hintere, zum Schneidwerk 6 hin geneigte Begrenzungsfläche 10 sowie durch in dieser Figur nicht dargestellte seitliche Wände 25 und 26, siehe Fig. 2, begrenzt ist. Oberhalb dieses Zuführschachtes 8 ist auf dem Gehäuseoberteil 4 ein Aufsatz 11 aufgesetzt, wobei in dem überdeckten Bereich die obere Fläche 4b des Gehäuseoberteiles 4 durch Herausnahme eines hier nicht dargestellten Gehäuseabschnittes zum Innenraum des Aufsatzes hin geöffnet ist. In besagtem Überdeckungsbereich ist eine untere Fläche 16 des aufgesetzten Aufsatzes 11 ebenfalls im wesentlichen geöffnet, so dass in den Innenraum des Aufsatzes 11 eingeschüttetes, sogenanntes Knüllmaterial von dem mit den Begrenzungswänden 13, 14, 15, 24 und 9, 10, 25, 26 gebildeten gemeinsamen Aufnahmeraum aus gezielt zum Schneidwerk 6 rutschen und durch selbiges in Streifen oder Partikel geschnitten werden kann. Um eine im wesentlichen störungsfreie Zufuhr des Knüllmateriales zum Schneidwerk zu gewährleisten, ist die besagte hintere Begrenzungsfläche 10 des Zuführschachtes 8, von der Oberkante des Gehäuseoberteiles 4 ausgehend zum Schneidwerk hin geneigt angeordnet. In Abhängigkeit von der Größe der Knäuel des Knüllmateriales kann es aber trotzdem zur Unterbrechung der Zuführung des Knüllmateriales zum Schneidwerk hin kommen.
Um dieses Problem mit kostengünstigen Mitteln zu lösen, sieht dieses Ausführungsbeispiel der Erfindung im Speziellen vor, dass im Innenraum des Aufsatzes 11 ein Materialschieber 17 angeordnet ist, welcher durch Betätigung, von oben herkommend das besagte Knüllmaterial in Richtung des Materialeinzugsspaltes 6d des Schneidwerkes 6 schiebt und notfalls an mindestens eine der Schneidwalzen 6a, 6b andrückt, so dass selbige das Knüllmaterial in Richtung Materialeinzugsspalt 6d mitreißt.The illustrations in FIGS. 1 and 2 are shown only partially in section to better illustrate the invention.
