Abstract

A shredder (12) for materials (16) such as documents, packaging or the like is connected to a vibration compacter (13) to form a unit (11). Apart from a cutting mechanism (14), the particles (17) fall into a container (20) which is clamped onto a vibrating frame (28) and stands on a roller conveyor (36). Compaction to one third of the usual particle body is possible. The vibration generator functions horizontally in one axis. <IMAGE>

Description

Derartige Vorrichtungen, die häufig auch Aktenvernichter genannt werden, dienen zum Zerkleinern von Dokumenten, jedoch auch von anderem Material, wie Abfallpapier, Verpackungen oder dergleichen. Sie haben ein Schneidwerk zum Zerkleinern des Materials. Insbesondere bei größeren Zerkleinerungsvorrichtungen macht das Volumen des zerkleinerten Materials bei Lagerung und Abtransport Probleme. Es ist daher bereits vorgeschlagen worden (siehe DE-A-34 12 307) an eine Zerkleinerungsvorrichtung unmittelbar eine Ballenpresse anzuschließen. Ballenpressen sind jedoch bau- und platzaufwendig und erfordern einen hohen Bedienungsaufwand.Such devices, which are often also called document shredders, are used to shred documents, but also other materials, such as waste paper, packaging or the like. You have a cutting unit to shred the material. The volume of the shredded material poses problems during storage and removal, particularly in the case of larger shredding devices. It has therefore already been proposed (see DE-A-34 12 307) to connect a baler directly to a comminution device. However, balers are construction and space consuming and require a lot of effort.

Es ist bereits eine dem Oberbegriff des Anspruchs 1 entsprechende Vorrichtung mit einer Abfallmühle mit Absackvorrichtung aus der DE-A-23 55 032 bekanntgeworden, bei der in ein schubkarrenartig fahrbares Sachstativ ein flexibler Sack eingehängt werden kann. Das Sackstativ ist an einem Rahmen anbringbar, der in vertikale Vibrationsbewegung gesetzt werden kann. Dadurch soll eine gute Packung des zerteilten Abfalls im Sack gewährleistet sein.A device corresponding to the preamble of claim 1 with a waste mill with a bagging device has already become known from DE-A-23 55 032, in which a flexible bag can be hung in a wheelbarrow-like traveling tripod. The bag tripod can be attached to a frame that can be set to vibrate vertically. This is supposed to ensure a good packing of the divided waste in the sack.

Aufgabe der Erfindung ist es, eine besonders für Dokumentenzerkleinerung geeignete, verbesserte Kombination aus Aktenvernichter und Vibrationsverdichter zu schaffen.The object of the invention is to provide an improved combination of document shredder and vibration compressor which is particularly suitable for document shredding.

Diese Aufgabe wird durch den Anspruch 1 gelöst.This object is solved by claim 1.

Obwohl kaum zu erwarten war, daß so leichtes Material wie beispielsweise Papierpartikel sich durch Vibration verdichten läßt, und eher noch eine Volumenvergrößerung durch Auflösen der z.T. beim Zerschneiden zusammengepreßten Partikellagen zu befürchten gewesen wäre, hat sich gezeigt, daß durch die horizontale Vibrationsverdichtung erstaunlicherweise eine Verdichtung auf etwa ein Drittel gegenüber dem unverdichteten Zustand möglich ist. Damit kommt aber das zerkleinerte Material in einen Raumgewichtsbereich von etwa 200 Kilogramm je Kubikmeter, der Lagerung und Transport rentabel macht. Ein Gebinde aus so verdichtetem zerkleinerten Material in einer üblichen Größe von ca. 70 x 70 x 60 cm hat danach eine Masse von etwa 60 kg, so daß es gerade noch handhabbar ist.Although it was hardly to be expected that such light material such as paper particles could be compressed by vibration, and rather an increase in volume by dissolving the partially. When cutting compressed layers of particles would have been to be feared, it has been shown that the horizontal vibration compression surprisingly enables compression to about a third compared to the undensified state. However, this means that the shredded material comes into a density range of around 200 kilograms per cubic meter, which makes storage and transport profitable. A container made of shredded material compacted in this way in a customary size of approx. 70 x 70 x 60 cm then has a mass of approximately 60 kg, so that it can just about be handled.

Vorteilhaft kann der Vibrationsverdichter mit der Zerkleinerungsvorrichtung eine Baueinheit bilden. Dies ist auch deswegen vorteilhaft, weil bei frei zusammengestellten Maschinen durch die Vibrationen eine gegenseitige Verschiebung der Einzelgeräte zu befürchten wäre. Der Vibrationsverdichter sollte möglichst unterhalb der Zerkleinerungsvorrichtung und insbesondere unterhalb von dessen Auswurföffnung angeordnet sein, so daß das zerkleinerte Gut unmittelbar in den Vibrationsverdichter gelangt. Dieser nimmt einen in Vibration versetzten Behälter auf, beispielsweise einen Karton aus wiederverwertetem Material (Recycle-Karton), der als Einwegbehälter zusammen mit seinem Inhalt, dem zerkleinerten Material gelagert und entsorgt werden kann. Es ist aber auch möglich, einen Dauerbehälter vorzusehen, der z. B. einen Papier- oder Kunststoffsack aufnimmt, in dem die Verdichtung stattfindet. Die Entnahme dieses Sackes kann dann entweder durch eine Tür in dem Behälter oder durch Entnahme und Umkippen des Behälters nach Verschließen des Sackes geschehen.The vibration compressor can advantageously form a structural unit with the comminution device. This is also advantageous because, in the case of freely assembled machines, the vibrations would have to fear a mutual displacement of the individual devices. The vibratory compactor should, if possible, be arranged below the comminution device and in particular below its ejection opening, so that the comminuted material reaches the vibratory compactor directly. This holds a vibrated container, for example a box made from recycled material (recycled cardboard), which can be stored and disposed of as a disposable container together with its contents, the shredded material. But it is also possible to provide a permanent container, the z. B. receives a paper or plastic sack in which the compression takes place. This sack can then be removed either through a door in the container or by removing and tipping over the container after the sack has been closed.

Es ist festgestellt worden, daß die Verdichtung mit zunehmender Füllhöhe in dem Behälter progressiv zunimmt. Offensichtlich wirkt das Gewicht des verdichteten Zerkleinerungsgutes auf die unteren Lagen komprimierend. Es ist dementsprechend vorteilhaft, wenn der Behälter eine Höhe hat, die seinen horizontalen Abmessungen etwa entspricht oder größer ist. Er sollte also nicht zu flach sein, um diese Wirkung zu fördern.It has been found that the compression increases progressively with increasing fill level in the container. Obviously, the weight of the compacted material has a compressing effect on the lower layers. Accordingly, it is advantageous if the container has a height that approximately corresponds to its horizontal dimensions or is greater. So it should not be too flat to promote this effect.

Der Behälter könnte an dem Vibrationsmechanismus unmittelbar angebracht sein. Vorzugsweise ist er jedoch von einer Halterung an dem Vibrationsmechanismus erfaßbar und kann vorzugsweise mit seinen unteren Seitenkannten daran eingespannt werden.The container could be attached directly to the vibration mechanism. However, it can preferably be grasped by a holder on the vibration mechanism and can preferably be clamped to it with its lower side edges.

Damit der Vibrationsmechanismus nicht das gesamte Gewicht des Behälters und des verdichteten Gutes aufzunehmen hat, kann er auf einer Bewegungsbahn, beispielsweise einer in Vibrationsrichtung wirksamen Rollenbahn oder einer Kugelführungsbahn stehen. Trotz seiner Randeinspannung kann, insbesondere bei Kartonbehältern, sich der Boden infolge seiner Durchbiegung auf den Rollen abstützen und belastet somit den Vibrationsmechanismus nicht mit dem gesamten Gewicht. Die Halterung sollte den Behälter relativ spielfrei erfassen, um bei der Vibration keine Relativbewegung zwischen der Halterung und dem Behälter zuzulassen, die diesen beschädigen könnte.So that the vibration mechanism does not have to take up the entire weight of the container and the compacted material, it can stand on a movement path, for example a roller track effective in the direction of vibration or a ball guide track. Despite its edge clamping, especially with cardboard containers, the base can be supported on the rollers due to its deflection and therefore does not burden the vibration mechanism with the entire weight. The holder should grip the container relatively free of play, so as to not allow any relative movement between the holder and the container during vibration, which could damage it.

Als Vibrationserzeuger kann ein üblicher Schwingungserzeuger verwendet werden, beispielsweise ein Elektro-Getriebemotor, dessen Antriebswelle über einen Exzenter auf den Vibrationsmechanismus, beispielsweise einen mit seinen Halterungen U-förmig den Behälterbereich umfassenden Rahmen, einwirkt.A conventional vibration generator can be used as the vibration generator, for example an electric geared motor, the drive shaft of which acts via an eccentric on the vibration mechanism, for example a frame which surrounds the container area with its holders in a U-shape.

Ein Hub zwischen 10 und 50 mm, vorzugsweise bei ca. 25 mm hat sich als vorteilhaft erwiesen und eine Vibrationsfrequenz zwischen 200 und 500 Zyklen je Minute, vorzugsweise bei 300 Zyklen je Minute.A stroke between 10 and 50 mm, preferably around 25 mm, has proven to be advantageous and a vibration frequency between 200 and 500 cycles per minute, preferably at 300 cycles per minute.

An den Vibrationsverdichter kann eine Zuführ- oder Abführstrecke für die Behälter bzw. ihren z.B. in Säcke verpackten verdichteten Inhalt angeschlossen werden. Dabei sind auch motorisch angetriebene Förderbänder oder Rollenbahnen möglich. Bei größerem Anfall von Material ist dies vorteilhaft. Es ist jedoch auch bei kleineren Einheiten möglich, die Behälter von Hand zu bewegen oder in der Bewegungsbahn entsprechende Ausnehmungen vorzusehen, um dort die Tragholme von Hubwagen oder Stapelladern einzufahren und die Behälter so an- und abzutransportieren.A feed or discharge path for the containers or their e.g. packed contents packed in sacks. Motorized conveyor belts or roller conveyors are also possible. This is advantageous when there is a large amount of material. However, it is also possible in the case of smaller units to move the containers by hand or to provide corresponding recesses in the movement path in order to retract the carrying struts of pallet trucks or stackers and to transport the containers in and out.

Die Erfindung hat zahlreiche Vorteile. Sie erfordert zwingend kein schwer zu entsorgendes Verpackungs- oder Hilfsmaterial, beispielsweise Spannbänder, wie bei Ballenpressen. Die Behälter können in der Form, in der sie nach der Verdichtung vorliegen, sofort entnommen werden. Es ist keine Expansion zu befürchten, wie beispielsweise nach dem Entnehmen der Ballen aus Ballenpressen. Deshalb können auch Papiersäcke zur Anwendung kommen. Der Behälter hat lediglich die Funktion, die Materialpartikel zusammenzuhalten und sie transportfähig zu machen. Es hat sich auch gezeigt, daß trotz der Vibration kaum Staub nach außen dringt. Die durch den Behälter oder Sack allseitig umschlossene, verdichtete Einheit verschmutzt auch die Umgebung nicht durch abfallende Einzelpartikel. Es wird vor allem ein wesentlich höherer Ausstoß der Gesamteinheit Zerkleinerungsvorrichtung/Vibrationsverdichter gegenüber beispielsweise einer Einheit Zerkleinerungsvorrichtung/Ballenpresse erzielt. Die Ballenpresse hat einen wesentlich höheren Handhabungsaufwand , beispielsweise für das Einlegen und Bedienen der Spanngurte, das Entnehmen etc.. Während dieser Zeiten kann die Zerkleinerungsvorrichtung nicht laufen, so daß die Laufzeit der Zerkleinerungsvorrichtung auf fast nur die Hälfte der Gesamtarbeitszeit beschränkt ist. Bei der Erfindung kann dagegen durch die geringere Entnahme- und Beschickungszeit für die Behälter die Zerkleinerungsvorrichtung einen wesentlich höheren prozentualen Anteil an effektiver Arbeitszeit haben, so daß der Ausstoß größer wird. Das Verhältnis bewegt sich dort bei drei zu eins, d.h. in einer Stunde kann die Zerkleinerungsvorrichtung 45 Minuten laufen und nur 15 Minuten dauert das Entnehmen der gefüllten Behälter und das Neubeschicken mit leeren Behältern. Dadurch kann der Ausstoß gegenüber der Kombination mit Ballenpresse wesentlich erhöht werden. Im Normalfall liegt der Ausstoß ca. 50 % höher. Bei automatischem Behälterwechsel ist eine Erhöhung bis zu 80 % ohne weiteres zu erreichen.The invention has numerous advantages. It does not require any packaging or auxiliary material that is difficult to dispose of, for example tensioning straps, such as balers. The containers can be removed immediately in the form in which they are after compaction. There is no fear of expansion, such as after removing the bales from balers. Therefore, paper bags can also be used. The container only has the function of holding the material particles together and making them transportable. It has also been shown that, despite the vibration, hardly any dust escapes. The compacted unit, which is enclosed on all sides by the container or sack, also does not pollute the environment with falling individual particles. Above all, there will be a much higher output of the entire unit Shredding device / vibration compactor compared to, for example, a shredding device / baler unit. The baler has a much higher handling effort, for example for inserting and operating the tension belts, removing etc. During these times, the shredding device can not run, so that the running time of the shredding device is limited to almost half of the total working time. In the case of the invention, on the other hand, due to the shorter removal and loading time for the containers, the comminution device can have a substantially higher percentage of effective working time, so that the output increases. The ratio is three to one, ie the shredder can run for 45 minutes in one hour and it takes only 15 minutes to remove the filled containers and refill them with empty containers. This can significantly increase the output compared to the combination with a baler. Normally the output is about 50% higher. With an automatic container change, an increase of up to 80% can easily be achieved.

Die Vibrationsverdichtung eignet sich insbesondere für Partikel, weil diese unter den bei der Vibration auftretenden Kräften sich gegeneinander verschieben, ohne aber wesentliche Verformungen zu erleiden, wie dies beispielsweise bei Streifen der Fall wäre. Deswegen ist ein Partikelschnitt bevorzugt, bei dem üblicherweise die Längen- und Breitenabmessungen in der gleichen Größenordnung liegen, wobei die genauen Längen/Breitenverhältnisse auch von der Absolutgröße der Partikel abhängen. Schmalere Partikel sind normalerweise etwas gestreckter als breitere.Vibration compression is particularly suitable for particles because they move against one another under the forces that occur during the vibration, but without suffering significant deformations, as would be the case, for example, with strips. For this reason, a particle cut is preferred in which the length and width dimensions are usually of the same order of magnitude, the exact length / width ratios also depending on the absolute size of the particles. Narrower particles are usually somewhat elongated than wider ones.

Der Vibrationsverdichter und gegebenenfalls auch die Zerkleinerungsvorrichtung kann über einen die Füllhöhe am Vibrationsverdichter abfühlenden Fühler steuerbar sein. Die Bedienungsperson braucht dann nicht darauf zu achten, ob der Behälter überfüllt wird. Wenn er voll ist, wird die Zerkleinerungsvorrichtung einfach abgeschaltet. Bei automatischen Anlagen könnte dadurch sogar ein automatischer Behälterwechsel eingeleitet werden, was mit Kartonbehältern durchaus möglich wäre.The vibration compressor and possibly also the comminution device can control the filling level on the vibration compressor sensing sensors can be controlled. The operator then need not pay attention to whether the container is overfilled. When it is full, the shredder is simply switched off. In the case of automatic systems, this could even initiate an automatic container change, which would certainly be possible with cardboard containers.

Zwischen Dauerbehältern, Einwegbehältern und Säcken sind auch alle Zwischenlösungen möglich. So könnte beispielsweise ein aus relativ dünnem Material bestehender Behälter auch in einen nur einen Teil der Höhe ausmachenden Dauerbehälter eingesetzt werden, der die Vibrationsbewegungen großflächiger auf den eingesetzten Einwegbehälter überträgt.All intermediate solutions are also possible between permanent containers, disposable containers and sacks. For example, a container made of relatively thin material could also be inserted into a permanent container that only accounts for part of the height and which transfers the vibration movements over a large area to the disposable container used.

Es sei bemerkt, daß Vibrationsvorrichtungen allgemein bekannt sind. So sind beispielsweise aus der DE-A-30 30 639, der DE-B-1 252 049 und der DE-A-38 37 686 Vibratoren und Schwingsysteme bekannt, die üblicherweise zum Antrieb von Rüttelsieben o.dgl. eingesetzt werden. Auch zum Verdichten von Beton, Erden oder dergleichen werden Vibratoren allgemein eingesetzt.It should be noted that vibrating devices are well known. For example, vibrators and vibration systems are known from DE-A-30 30 639, DE-B-1 252 049 and DE-A-38 37 686, which are commonly used to drive vibrating screens or the like. be used. Vibrators are also generally used for compacting concrete, earth or the like.

Die in Fig. 1 dargestellte Einheit 11 besteht aus einer Zerkleinerungsvorrichtung 12 und einem Vibrationsverdichter 13. Die Zerkleinerungsvorrichtung 12 enthält ein von einem nicht dargestellten Elektromotor angetriebenes Schneidwerk 14, dessen Schneidwalzen aus wechselweise ineinander eingreifenden und miteinander zusammenwirkenden Schneidscheiben bestehen. Sie können an ihrem Umfang Ausnehmungen haben oder insgesamt sternförmig ausgebildet sein, um bei ihrem gegenläufigen Antrieb die über einen Zuführtisch 15 eingebrachten Materialien 16, wie Dokumente, Bücher, Verpackungskartons o.dgl. nicht nur in Streifen zu zerschneiden, sondern diese auch längs zu trennen, so daß Partikel entstehen, deren Länge in der gleichen Größenordnung liegt wie ihre Breite.The unit 11 shown in FIG. 1 consists of a comminution device 12 and a vibration compressor 13. The comminution device 12 contains a cutting mechanism 14 driven by an electric motor, not shown, the cutting rollers of which consist of mutually interlocking and interacting cutting disks. They can have recesses on their circumference or be designed in a star shape overall, in order to drive the materials 16 introduced via a feed table 15, such as documents, books, packaging boxes or the like, in the opposite direction. not only to cut into strips, but also to separate them lengthways so that particles are formed whose length is of the same order of magnitude as their width.

Die entstehenden Partikel 17 können, da die Materialien meist in Form von Blattlagen eingegeben werden, ebenfalls Lagen von Einzelblatt-Partikeln sein, die durch den Schneidvorgang teilweise auch zusammengepreßt und ineinander verzahnt sind. Sie fallen durch eine Ausgabeöffnung 18 aus der Zerkleinerungsvorrichtung nach unten heraus in einen Behälter 20, der in einem Aufnahmeraum 19 des Vibrationsverdichters 13 steht.The resulting particles 17, since the materials are mostly entered in the form of sheet layers, can also be layers of single sheet particles, which are also partially compressed and interlocked by the cutting process. They fall down through an output opening 18 from the comminution device into a container 20 which is located in a receiving space 19 of the vibration compressor 13.

Der Vibrationsverdichter hat einen Maschinenrahmen 21, der auf dem Boden steht und auf dessen Oberseite die Zerkleinerungsvorrichtung 12 fest montiert ist, so daß beide Maschinen eine zusammenhängende Einheit bilden. In dem Rahmen ist zwischen Vertikalholmen 22 ein Vibrations- oder Schwingungserzeuger 23 angebracht, der aus einem Elektro-Getriebemotor 12 besteht, an dessen Ausgangswelle 25 ein Exzenter 26 montiert ist, der eine Kurbelschwinge 27 antreibt. Sie steht mit einem eine Halterung 29 für den Behälter 20 bildenden Seitenholm eines Schwingrahmens 28 gelenkig in Verbindung, so daß bei Drehung der Welle der Schwingrahmen insgesamt in eine einachsige Vibration oder Schwingung versetzt wird, deren Bewegungsrichtung horizontal und in Fig. 1 senkrecht zur Zeichenebene gerichtet ist.The vibration compactor has a machine frame 21 which stands on the floor and on the top of which the comminution device 12 is fixedly mounted, so that both machines form a coherent unit. In the frame, a vibration or vibration generator 23 is attached between vertical bars 22 and consists of an electric gear motor 12, on the output shaft 25 of which an eccentric 26 is mounted, which drives a crank arm 27. It is connected in an articulated manner to a side member of a swinging frame 28 which forms a holder 29 for the container 20, so that when the shaft rotates, the whole of the swinging frame is set in a uniaxial vibration or oscillation, the direction of movement of which is horizontal and in FIG is.

Der Schwingrahmen 28 besteht aus zwei zueinander parallelen Halterungen 29 und diese verbindenden Verbindungsstangen 30, die zu beiden Seiten des Vibrationserzeugers 23 verlaufen und in Führungen 31 verschiebbar geführt sind, so daß sie die beschriebene Schwingbewegung ausführen können. Die beiden Halterungen kragen senkrecht zu den Verbindungstangen so aus, daß sie einen einseitig offenen Rahmen bilden und den Behälter 20 im Bereich seiner unteren Seitenkannten zwischen sich aufnehmen und festklemmen. Zu diesem Zweck ist die in Fig. 2 linke Halterung auf den Verbindungsstangen verschiebbar geführt. Federn 32 drücken die Halterung 29 zur Maschinenmitte hin und spannen so den Behälter 20 ein.The oscillating frame 28 consists of two mutually parallel brackets 29 and connecting rods 30 connecting them, which extend on both sides of the vibration generator 23 and are guided in guides 31 so that they can carry out the described oscillating movement. The two brackets protrude perpendicular to the connecting rods so that they form a frame open on one side and receive and clamp the container 20 in the area of its lower side edges between them. For this purpose, the left bracket in Fig. 2 is slidably guided on the connecting rods. Springs 32 press the holder 29 towards the center of the machine and thus clamp the container 20.

Es ist angedeutet, daß über eine an einem Holm des Rahmens 21 angebrachte Öffnungsmechanik 33 die linke Halterung 29 im Öffnungssinne, d.h. in Fig. 2 nach links, gezogen werden kann, wenn eine den Arbeitsraum 19 aus Sicherheitsgründen verschließende Tür 34 geöffnet wird. Die Öffnungsmechanik 33 ist als ein Bowdenzug dargestellt, der beim Öffnen der Tür die Halterung 29 entgegen der Kraft der Feden 32 öffnet, so daß der Behälter 20 dann automatisch freigegeben wird. Da die Tür 34 auch einen nicht dargestellten Sicherheitsschalter betätigt, der den Vibrationsverdichter und gegebenenfalls auch die Zerkleinerungsvorrichtung nur dann in Betrieb setzt, wenn die Tür geschlossen ist, ist für einen sicheren und störungsfreien Betrieb gesorgt.It is indicated that the left bracket 29 can be pulled in the opening direction, ie to the left in FIG. 2, via an opening mechanism 33 attached to a spar of the frame 21 when a door 34 closing the work space 19 for safety reasons is opened. The opening mechanism 33 is shown as a Bowden cable when the door is opened the holder 29 opens against the force of the springs 32, so that the container 20 is then automatically released. Since the door 34 also actuates a safety switch, not shown, which only starts the vibration compressor and possibly also the comminution device when the door is closed, safe and trouble-free operation is ensured.

Unterhalb des Behälters 20 sind auf dem Boden oder an Quertraversen 35 des Rahmens Rollenbahnen 36 angebracht, deren Rollen 37 eine Abrollrichtung parallel zur Schwingungsrichtung haben. Sie bilden eine Standebene 38 für den Behälter 20, auf der sich dessen Boden abstützen kann. Durch die Rollen 37 kann er sich unter den durch die Halterungen 29 übertragenen Vibrationskräften entsprechend bewegen. Die Vibrations- oder Schwing-Hübe können einstellbar sein. Ein Schwingungserzeuger der dargestellten und beschriebenen Art ist bevorzugt, weil mit ihm ein relativ großer, von der in Schwingung zu versetzenden Masse unabhängiger Hub erzeugt werden kann. Es sind jedoch auch andere Schwingungserzeuger, beispielsweise vom Unwucht-Typ, möglich.Below the container 20, roller conveyors 36 are mounted on the floor or on cross members 35 of the frame, the rollers 37 of which have a rolling direction parallel to the direction of vibration. They form a standing level 38 for the container 20 on which the bottom thereof can be supported. The rollers 37 enable it to move accordingly under the vibration forces transmitted through the brackets 29. The vibration or swing strokes can be adjustable. A vibration generator of the type shown and described is preferred because it can be used to generate a relatively large stroke which is independent of the mass to be vibrated. However, other vibration generators, for example of the unbalance type, are also possible.

Für den Fall einer automatischen Entnahme wäre es auch möglich, statt der Rollenbahnen 36 Kugelführungsbahnen einzusetzen, die auch eine Bewegung parallel zu den Halterungen 29 ermöglichen, um die Behälter auch in Richtung der Tür verschieben zu können. Im vorliegenden Fall entstehen jedoch zwischen den Rollenbahnen 36 Lücken, in die eine Gabel eines Hubwagens oder eines Stapelladers eingreifen kann, um einen Behälter von der Rollenbahn abzuheben und durch die Tür 34 zu entnehmen.In the case of an automatic removal, it would also be possible to use ball guide tracks instead of the roller tracks 36, which also allow movement parallel to the holders 29 in order to be able to also move the containers in the direction of the door. In the present case, however, there are gaps between the roller conveyors 36, into which a fork of a lifting truck or a stacking loader can engage in order to lift a container from the roller conveyor and remove it through the door 34.

Die Figuren 3 und 4 zeigen eine entsprechend aufgebaute Einheit, die jedoch durch seitlich angrenzende Rollenbahnen 39 vervollständigt ist, auf denen leere Behälter 20 antransportiert und gefüllte abrtansportiert weden können. In diesem Falle können sie durch seitliche Öffnungen des Rahmens 21 in den den Arbeitsraum 19 hinein- und hinaustransportiert werden. In diesem Falle wäre es zweckmäßig, beide Halterungen 29 absenkbar oder abschwenkbar zu gestalten, so daß die Behälter in Höhe der Standebene 38 hinein- und hinausgeschoben werden können.FIGS. 3 and 4 show a correspondingly constructed unit, which, however, is arranged by laterally adjacent roller tracks 39 is completed, on which empty containers 20 can be transported and filled can be transported away. In this case, they can be transported into and out of the work space 19 through lateral openings in the frame 21. In this case, it would be expedient to make both holders 29 lowerable or pivotable so that the containers can be pushed in and out at the level 38.

Die Einheit arbeitet wie folgt:
Vor Beginn des Betriebes wird ein Behälter 20 auf die Standebene 38 aufgestellt. Bei dem Behälter kann es sich um einen oben offenen Karton handeln, dessen Deckellaschen 40 außen an die Seitenwände herangeklappt und an ihren unteren Ecken durch Aufreißlaschen 41 miteinander verbunden sind (Fig. 1). Es ist jedoch auch möglich, einen öfter einzusetzenden Dauerbehälter zu verwenden, in den ein Papier- oder Kunststoffsack eingelegt ist, dessen öffnungsnahe Bereiche über die Behälteraußenseiten nach unten gezogen sind, d.h. etwa wie die in Fig. 1 dargestellten Deckelteile 40.
The unit works as follows:
Before the start of operation, a container 20 is placed on the stand level 38. The container can be a cardboard box open at the top, the cover flaps 40 of which are folded out onto the side walls on the outside and are connected to one another at their lower corners by tear-open flaps 41 (FIG. 1). However, it is also possible to use a permanent container to be used more often, in which a paper or plastic sack is inserted, the regions of which close to the opening are pulled downward over the outside of the container, ie approximately like the cover parts 40 shown in FIG. 1.

Nach Schließen der Tür 34 gibt die Öffnungsmechanik 33 die Halterung 29 frei, die nach dem anfänglichen Öffnen der Tür unter Spannung der Federn 32 in Öffnungsposition gebracht worden war. Dadurch wird der untere, bodennahe Bereich der Seitenwände des Behälters 20 zwischen den Halterungen 29 eingespannt, und zwar unter der gleichmäßigen Spannkraft der Federn 32. Die Einheit ist nunmehr betriebsbereit.After closing the door 34, the opening mechanism 33 releases the holder 29, which had been brought into the open position after the initial opening of the door under tension of the springs 32. As a result, the lower, near-ground area of the side walls of the container 20 is clamped between the brackets 29, namely under the uniform clamping force of the springs 32. The unit is now ready for operation.

Über den Eingabetisch 15 werden die zu zerkleinerten Materialien 16 eingeschoben. Der Tisch kann auch ein Förderband enthalten. Im Schneidwerk 14 werden die Materialien in Partikel 17 zerlegt und fallen durch die untere Ausgabeöffnung 18 der Zerkleinerungsvorrichtung 12 in den Behälter 20. Zugleich mit der Inbetriebsetzung der Zerkleinerungsvorrichtung 12 wurde der Schwingungserzeuger 23 in Gang gesetzt, so daß über den Exzenter 26 und die Kurbelschwinge 27 der Schwingrahmen 28 in Schwingungsrichtung (Teil 42 in Fig. 2) in Schwingung versetzt wird. Die in den Behälter fallenden Partikel werden durch die horizontale einachsige Schwingung soweit ausgerichtet, daß sie eine wesentlich dichtere Schüttung einnehmen als nach ihrem Hineinfallen in den Behälter. Durch die Vibration wird auch der Sicherheitseffekt noch weiter erhöht, weil auf dem Originalmaterial nebeneinanderliegende Partikel, die meist auch benachbart in den Behälter hineinfallen, gegeneinander verschoben und damit ein Wieder-Zusammenfügen erschwert wird.The materials 16, which have been comminuted, are inserted over the input table 15. The table can also contain a conveyor belt. In the cutting unit 14, the materials are broken down into particles 17 and fall through the lower discharge opening 18 the shredding device 12 into the container 20. Simultaneously with the commissioning of the shredding device 12, the vibration generator 23 was started so that the eccentric 26 and the crank arm 27 cause the vibration frame 28 to vibrate in the direction of vibration (part 42 in FIG. 2) . The horizontal uniaxial vibration aligns the particles falling into the container to such an extent that they take up a much denser bed than after they fell into the container. The vibration also increases the safety effect because particles lying next to each other on the original material, which usually also fall into the container adjacent to one another, are shifted against each other and thus difficult to reassemble.

Es bildet sich so ein relativ dichtes Schüttgut, das mit ca. 200 Kilogramm je Kubikmeter vergleichbar dicht ist. Insbesondere im unteren Teil wirken die darüberliegenden Partikel ebenfalls verdichtend. Über einen Füllstandsfühler 44, der als optischer, Ultraschallfühler oder über eine Wiegezelle in Abhängigkeit von dem Behältergewicht arbeiten kann, wird die Füllhöhe überwacht und nach Füllung des Behälters das Gerät einschließlich der Zerkleinerungsvorrichtung abgeschaltet. Dabei kann der Vibrationsverdichter 13 noch eine Zeit nachlaufen, um die Verdichtung zu vervollständigen. Die Bedienungsperson kann nun die Tür 34 öffnen, wodurch über die Öffnungsmechanik 33 die Halterung 29 geöffnet wird und der Behälter nunmehr von Hand oder mit einem Hubstapler entnommen werden kann. Er wird dann durch Hochklappen der Deckelteile 40 nach Aufreißen der Laschen 41 geschlossen und kann so gelagert oder einer Altpapieraufbereitung zugeführt werden.A relatively dense bulk material is formed that is comparatively dense at around 200 kilograms per cubic meter. In the lower part in particular, the particles above also have a densifying effect. The fill level is monitored via a fill level sensor 44, which can function as an optical, ultrasonic sensor or via a weighing cell depending on the container weight, and the device including the comminution device is switched off after the container has been filled. The vibration compressor 13 can run a while longer to complete the compression. The operator can now open the door 34, whereby the holder 29 is opened via the opening mechanism 33 and the container can now be removed by hand or with a forklift. It is then closed by folding up the lid parts 40 after the tabs 41 are torn open and can thus be stored or fed to a waste paper processing facility.

Auch das Einsetzen eines neuen Behälters geht sehr schnell und nach Schließen der Tür kann die Vorrichtung bereits wieder betrieben werden.The insertion of a new container is also very quick and after closing the door, the device can be operated again.

Eine weitere Steigerung der anteiligen Nutz-Arbeitszeit der Einheit kann erreicht werden, wenn nach Fig. 3 und 4. die Behälterbeschickung über Rollenbahnen praktisch im Durchlauf erfolgt. Die motorisch angetriebenen Rollenbahnen können von den Ein- bzw. Ausschaltimpulsen der Einheit betrieben werden, so daß der Bediener sich um die Behälterbeschickung und Entnahme selbst gar nicht mehr zu kümmern hat. In diesem Falle würde auch die Klemmung der Behälter durch die Halterungen durch elektrischen und pneumatischen Antrieb bewirkt werden.A further increase in the proportionate useful working time of the unit can be achieved if, according to FIGS. 3 and 4, the container is loaded practically in one pass via roller conveyors. The motor-driven roller conveyors can be operated by the switch-on or switch-off pulses of the unit, so that the operator no longer has to take care of the container loading and removal himself. In this case, the containers would also be clamped by the holders by means of electrical and pneumatic drives.

Im Falle, daß als Aufbewahrung für die zerkleinerten Materialien Papier- oder Kunststoffsäcke verwendet werden, wird der Behälter nach seiner Entnahme und nach Schließen des Sackes umgekippt oder einseitig geöffnet und der gefüllte Sack entnommen. Dabei kann zur Beschleunigung der Betriebsbereitschaft ein zweiter Behälter schon wieder in das Gerät eingesetzt sein. Es wäre aber auch möglich, einen Behälter im wesentlichen fest in den Vibrationsverdichter einzubauen und ihn mit einer Öffnungsklappe zu versehen, über die ein Sack oder Behälter direkt entnommen werden kann.In the case that paper or plastic sacks are used as storage for the shredded materials, the container is tipped over after its removal and after the sack is closed or opened on one side and the filled sack is removed. In order to accelerate the operational readiness, a second container can already be inserted into the device again. However, it would also be possible to install a container essentially firmly in the vibration compressor and to provide it with an opening flap, via which a sack or container can be removed directly.

Der Hub und die Vibrationsfrequenz hängen auch von der Partikelgröße ab. So sollte der Hub bei größeren Partikeln größer gewählt werden, damit sichergestellt wird, daß die Partikel sich auf ein möglichst minimales Volumen ausrichten.The stroke and vibration frequency also depend on the particle size. For larger particles, the stroke should be chosen larger to ensure that the particles align themselves with the smallest possible volume.
