Abstract

A feed device (22), which has a plurality of compartments (23) inclined slightly towards the rear relative to the vertical, is provided for shredding computer printouts which are in the form of web piles (26) folded in a zigzag manner. The webs (17) are drawn from the piles (26) located in said compartments via the web guide (33) formed by the respective front edge of the compartment. A projection (29) formed by a wire bar holds the pile back when it is pulled along upwards during the drawing-off. <IMAGE>

Description

Während normalerweise einem Dokumentenvernichter die Dokumente, und darunter sind Flachmaterialien und Schriftgut beliebiger Art zu verstehen, in einzelnen Blättern oder Stapeln zugeführt werden, kommt es häufig vor, daß ganze Stapel von in gefalzten Lagen vorliegenden Flachmaterialbahnen, beispielsweise Ausdrucke von Datenverarbeitungsanlagen, wegen ihrer Vertraulichkeit vernichtet werden sollen. Nicht immer sind die Aktenvernichter dazu eingerichtet, die Stapel im Stück zu vernichten.While documents are normally fed to a document shredder, and this includes flat materials and documents of any kind, in individual sheets or stacks, it often happens that entire stacks of flat material webs in folded layers, for example printouts from data processing systems, are kept confidential to be destroyed. The shredders are not always set up to shred the stacks in one piece.

Aufgabe der Erfindung ist es daher, eine Zuführeinrichtung für Dokumentenvernichter zu schaffen, mit der störungsfrei die Bahnen in Folge zugeführt werden können.The object of the invention is therefore to provide a feed device for document shredders with which the webs can be fed in succession without interference.

Dazu ist nach der Erfindung wenigstens ein Fach vorgesehen, in das ein Stapel einlegbar ist und aus der über eine Bahnführung eine Bahn abgezogen werden kann.For this purpose, according to the invention, at least one compartment is provided, into which a stack can be inserted and from which a web can be drawn off via a web guide.

Dieses Fach ist vorteilhaft so angeordnet, daß der Stapel mit einer geringen Neigung von der Abziehseite, also vom Einführschlitz des Aktenvernichters weg, jedoch ziemlich steil steht. Dadurch liegt er zwar einerseits definiert an einer Anlageseite an, während auf der anderen Seite abgezogen bzw. "abgestapelt" wird, er nimmt aber trotzdem nicht viel Platz ein. Dadurch können auch mehrere Fächer hintereinander angeordnet sein.This compartment is advantageously arranged so that the stack with a slight inclination from the pull-off side, ie away from the insertion slot of the document shredder, is rather steep. As a result, it lies on one side of the system in a defined manner while being pulled or "stacked" on the other side, but it still does not take up much space. This means that several compartments can also be arranged one behind the other.

Die Bahn wird vorzugsweise über die an die Einführöffnung angrenzende obere vordere Kante abgezogen. Im Fall mehrerer beschickter Fächer laufen die Bahnen dann über das andere Fach hinweg und gemeinsam in den Dokumentenvernichter.The web is preferably drawn off over the upper front edge adjoining the insertion opening. In the case of several loaded compartments, the webs then run over the other compartment and together in the document shredder.

Dieser zieht durch seinen Eingriff mit der Bahn diese sicher ein.By engaging with the train, the latter pulls it in safely.

Insbesondere bei EDV-Druckmaterial kommt es in den aus zick-zack-gefalzten Lagen bestehenden Stapeln oft zu Verhakungen im Randbereich, beispielsweise an den perforierten Rändern. Dies kann dazu führen, daß der Stapel beim Abziehen hochgerissen wird und aus der Einführöffnung herausschnellt. Aus diesem Grunde ist vorzugsweise im Bereich der Einführöffnung ein über die Anlageseite vorstehender Vorsprung vorgesehen, an dem dann die obere Stapelkante anschlägt. Dadurch ist ausreichender Widerstand vorhanden, daß sich die Verhakung lösen kann.In the case of computer print material in particular, the stacks consisting of zigzag-folded layers often get caught in the edge area, for example on the perforated edges. This can result in the stack being torn up when it is pulled off and snapping out of the insertion opening. For this reason, a projection projecting beyond the contact side is preferably provided in the region of the insertion opening, against which the upper stack edge then strikes. As a result, there is sufficient resistance that the hooking can come loose.

Die Zuführeinrichtung kann mit einem oder mehreren Fächern als zusammenhängende Baueinheit vorgesehen sein, die an der Oberseite eines Aktenvernichters angebracht werden kann, beispielsweise durch Einstecken in Schlitze oder Öffnungen. Es ist jedoch auch möglich, das Fach aus einzelnen plattenförmigen Elementen aufzubauen.The feed device can be provided with one or more compartments as a coherent structural unit which can be attached to the top of a document shredder, for example by inserting it into slots or openings. However, it is also possible to construct the compartment from individual plate-shaped elements.

Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und der Zeichnung hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführunbgen darstellen können, für die hier Schutz beansprucht wird.These and other features of preferred developments of the invention are evident from the claims and also from the description and the drawing, the individual features being implemented individually or in groups in the form of subcombinations in the embodiment of the invention and in other fields, and can represent advantageous and protectable versions for which protection is claimed here.

Die einzige Zeichnungsfigur zeigt eine teilgeschnittene Seitenansicht einer Zuführeinrichtung an einem Dokumentenvernichter.The only drawing figure shows a partially sectioned side view of a feed device on a document shredder.

Ein Dokumentenvernichter 11 hat an seinem Gehäuse eine obere Ablagefläche 12 und einen Einführtrichter 13, aus dem ein schmaler Einführschlitz 14 zu einem Schneidwerk 15 führt. Das aus zwei Schneidwalzen 16 bestehende Schneidwerk kann ein ein- oder mehrlagiges Flachmaterial 17 einziehen und in Streifen oder Partikel 18 zerkleinern.A document shredder 11 has on its housing an upper storage surface 12 and an insertion funnel 13, from which a narrow insertion slot 14 leads to a cutting unit 15. The cutting unit consisting of two cutting rollers 16 can draw in a single or multi-layer flat material 17 and comminute it into strips or particles 18.

An der Ablagefläche sind mehrere parallel zueinander und zum Einführschlitz 15 verlaufende Schlitze 19 vorgesehen, die normalerweise durch Einsteckleisten 20 verschlossen sind, deren Oberseite eine Dokumentenablage bildet. Aus zweien dieser Schlitze sind die Leisten 20 entfernt, und es sind Einsteckfüsse 21 einer Zuführeinrichtung 22 darin eingesteckt.Provided on the storage surface are a plurality of slots 19 which run parallel to one another and to the insertion slot 15 and which are normally closed by insert strips 20, the upper side of which forms a document storage area. The strips 20 are removed from two of these slots, and insertion feet 21 of a feed device 22 are inserted therein.

Die Zuführeinrichtung besteht aus einer Drahtkonstruktion, die drei Fächer 23 abgrenzt, die unten durch Draht-Bodenstreben 24 abgegrenzt sind. Die Fächer stehen beim Ausführungsbeispiel unter einem Winkel von 10° gegen über der Vertikalen nach hinten geneigt. Dieser Neigungswinkel kann zwischen 5 und 45°, vorzugsweise zwischen 10 und 20° betragen. Je geringer er ist, um so raumsparender lassen sich mehrere Fächer anordnen. Er muß jedoch so groß sein daß sich eine eindeutige Anlageseite 25 bildet, an der ein Stapel 26 aus zick-zack-gefalzten Lagen einer Flachmaterialbahn daran anlegen kann, der im übrigen auf seiner unteren Stapelkante 27 steht.The feed device consists of a wire construction, which delimits three compartments 23, which are delimited below by wire floor struts 24. In the exemplary embodiment, the compartments are inclined at an angle of 10 ° to the rear relative to the vertical. This angle of inclination can be between 5 and 45 °, preferably between 10 and 20 °. The smaller it is, the more space can be arranged in several compartments. However, it must be so large that a clear contact side 25 is formed, on which a stack 26 of zigzag folded Layers of a flat material web can create it, which is otherwise on its lower stack edge 27.

Die Anlageseite wird von senkrechten Drahtsprossen gebildet. Sie ist von einem aus etwas dickeren Draht bestehenden Rahmen 28 am Außenumfang umgeben, und zwar auf der zum Fach gerichteten Seite. Dadurch bildet der obere Holm 29 des Rahmens 28 einen Vorsprung, der über die Anlageseite in das Fach hineinragt, und zwar im Bereich der Einführöffnung 30 des Fachs 23. Die oberen, parallel zum Holm 29 verlaufenden Teile der die Anlageseite bildenden Sprossen 31 bilden zusammen mit dem Holm eine Bahnführung, über die die Bahn 17 durch die Einführöffnung 30 abgezogen wird. Von dort aus verläuft sie schräg nach unten in den Einführschlitz 14.The plant side is formed by vertical wire rungs. It is surrounded by a somewhat thicker wire frame 28 on the outer circumference, on the side facing the compartment. As a result, the upper spar 29 of the frame 28 forms a projection which projects into the compartment via the contact side, in the region of the insertion opening 30 of the compartment 23. The upper parts of the rungs 31 forming the contact side, which run parallel to the spar 29, form together with a web guide, through which the web 17 is drawn off through the insertion opening 30. From there, it runs obliquely down into the insertion slot 14.

Seitenbügel 32 versteifen die Baueinheit aus drei Fächern und führen den Stapel seitlich.Side brackets 32 stiffen the assembly from three compartments and guide the stack laterally.

Der Rahmen 28 hat auch einen Bodenholm 34, der, wie aus der Zeichnung zu sehen ist, den Stapel , wenn er auf den Bodenstreben 24 steht, etwas nach vorn von der Anlageseite 25 hinweg krümmt. Mehrere Fächer können gleichzeitig mit Stapeln 26 beschickt werden, wobei jeweils die hinteren Bahnen über die Einführöffnungen 30 der vorderen Fächer 23 verlaufen, um dann über die vorderste Bahnführung 33 hinweg mehrlagig abwärts zu laufen. Jeder Stapel kann auch aus mehrlagigen Bahnen bestehen kann.The frame 28 also has a floor spar 34 which, as can be seen from the drawing, bends the stack somewhat forwardly from the contact side 25 when it stands on the floor struts 24. A plurality of compartments can be loaded with stacks 26 at the same time, the rear webs each running over the insertion openings 30 of the front compartments 23, in order then to run downwards in multiple layers over the front web guide 33. Each stack can also consist of multilayered webs.

Die Zuführeinrichtung kann leicht an- und abgebaut werden, indem zwei Leisten 20 entfernt werden und die Füsse 21 in die Schlitze 19 eingesteckt werden. Die einzelnen Fächer werden dann mit Stapeln durch die Einführöffnungen 30 von oben her beschickt und der Bahnanfang über die jeweilige Fachoberkante, die die Bahnführung 33 bildet, gezogen und in den Einführschlitz 14 eingeführt.The feed device can be easily attached and removed by removing two strips 20 and inserting the feet 21 into the slots 19. The individual compartments are then loaded with stacks through the insertion openings 30 from above, and the beginning of the web is pulled over the respective upper edge, which forms the web guide 33, and inserted into the insertion slot 14.

Wenn das Schneidwerk 15 die Bahnen erfaßt hat, läuft die weitere Vernichtung automatisch ab, indem sich Lage für Lage selbst abzieht. In dem mittleren Fach 23 ist dargestellt, daß sich eine Verhakung gebildet hat. Die nach oben abgezogene Bahn 17 zieht daher den Stapel nach oben, der an seiner Anlageseite 25 nach oben geschoben wird. Er schlägt dann mit seiner oberen Stapelkante 40 an dem Holm bzw. Vorsprung 29 an, so daß jetzt ein ausreichender Widerstand vorhanden ist, um die Verhakung zu lösen. Der Stapel rutscht dann wieder nach unten in seine Ausgangslage.When the cutting unit 15 has grasped the webs, the further destruction takes place automatically, by stripping itself layer by layer. In the middle compartment 23 it is shown that a hook has formed. The upwardly drawn web 17 therefore pulls up the stack which is pushed upwards on its contact side 25. It then strikes with its upper stack edge 40 on the spar or projection 29, so that there is now sufficient resistance to release the hooking. The stack then slides back down to its starting position.

An dem linken Stapel ist zu erkennen, daß er sich, wenn er normal auf den Bodenstreben 24 steht, infolge des unteren Holms 34 etwas nach vorn neigt, so daß der Abzugwinkel etwas stumpfer wird und damit anfängliche Verhakungen im unteren Bereich leichter gelöst werden.It can be seen from the stack on the left that, when it is standing normally on the floor struts 24, it tilts somewhat forward as a result of the lower spar 34, so that the pull-off angle becomes somewhat obtuse and initial catches in the lower region are thus more easily released.

Im vorliegenden Fall sind nur zwei der drei Fächer beschickt. Bei Beschickung auch des dritten Faches würde die dritte Bahn über die anderen hinweglaufen.In the present case, only two of the three compartments are loaded. If the third compartment were also loaded, the third run would run over the others.

Die Ausführung als Drahtkonstruktion ist recht stabil und bietet guten Einblick in den jeweiligen Füllstand. Es könnte jedoch auch eine Fachkonstruktion aus anderem Material, z.B. Kunststoff, verwendet werden. Ein großer Vorteil ist, daß durch die Zuführeinrichtung andere Teile des Dokumentenvernichters, beispielsweise die Vorderseite, frei bleiben. Wenn man nämlich den Stapel vor dem Dokumentenvernichter anordnen würde, um von dort aus einzuziehen, dann würden wichtige Bedienungselemente, beispielsweise die Entleerungstür, blockiert werden, und der Betrieb würde gestört werden. Die hier beschriebene Zuführeinrichtung stört nicht. Wenn man die Vordertür zur Entleerung des Abfallbehälters öffnet, so bleibt der Dokumentenvernichter aufgrund der integrierten Sicherheitsabschaltung stehen, läuft aber nach dem Schließen der Tür automatisch wieder an, ohne daß es irgendeines weiteren Handgriffes bedürfte. Die Zuführeinrichtung stört auch nicht bei Verwendung des Aktenvernichters für Einzelblätter und kann deswegen auch permanent angebracht bleiben. Sogar während des laufenden Bahnvernichtungsbetriebes können zusätzlich Einzelblätter in den freien Einführtrichter eingebracht werden.The design as a wire construction is quite stable and offers good insight into the respective level. However, a specialist construction made of a different material, e.g. Plastic. A great advantage is that other parts of the document shredder, for example the front, remain free through the feed device. If the stack were to be placed in front of the document shredder to move in from there, then important operating elements, for example the emptying door, would be blocked and the operation would be disrupted. The feed device described here does not interfere. If you open the front door to empty the waste container, the document shredder stops due to the integrated safety shutdown, but starts again automatically after the door is closed without any further action being required. The feeder does not interfere with the use of the shredder for single sheets and can therefore remain permanently attached. Even while the web is being destroyed, additional sheets can be fed into the free insertion funnel.

Es ist daher auch möglich, ein oder mehrere Fächer, z.B. in flacherer Neigung, in die obere Gehäusebegrenzung mit einzuformen, die dann eine etwa sägezahnartige Ausbildung bekommen würde.It is therefore also possible to include one or more compartments, for example with a flatter slope, in the upper housing boundary, which would then have an approximately sawtooth-like design.

Vorteilhaft ist es auch, daß die von den Bodenstreben 24 gebildete Unterkante des Fachs einen gewissen Winkel gegenüber der durch die Anlageseite 25 bestimmten Stapelebene hat. Dadurch stößt der Stapel beim Einführen und bei jeder durch das Abziehen bedingten Bewegung schräg auf, so daß sich eventuelle Stapelverhakungen leicht lösen.It is also advantageous that the lower edge of the compartment formed by the floor struts 24 has a certain angle with respect to the stacking plane determined by the contact side 25. As a result, the stack slants openly during insertion and with every movement caused by the pulling off, so that any stacking hooks can easily be released.
