Description

Vorrichtung zum Kompaktieren von Hohlkörpern, insbesondere  Device for compacting hollow bodies, in particular
Getränkeblechdosen  beverage cans
Die vorliegende Erfindung betrifft eine Vorrichtung zum Kompaktieren von Hohlkörpern, insbesondere von Getränkeblechdosen, gemäß dem Oberbegriff des Anspruchs 1. The present invention relates to a device for compacting hollow bodies, in particular beverage tin cans, according to the preamble of claim 1.
Vorrichtungen zum Kompaktieren von Hohlkörpern sind aus dem Stand der Technik in vielfältigen Ausführungen bekannt. Bei diesen Vorrichtungen arbeitet häufig eine Walze gegen ein Gegenlager, wobei zwischen diesen beiden Bauteilen ein Einzugsspalt für die zu kompaktierenden Hohlkörper besteht. Von der Walze ragen radial Einzugselemente ab, die zum einen der Verbesserung des Einzugs und zum anderen der Kompaktierung der Hohlkörper dienen. In den meisten Fällen ist das Gegenlager eine andere Walze. Das Gegenlager kann aber auch durch ein z.B. plattenförmiges Bauteil gebildet sein, das eine ebene oder gewölbte Widerlagerfläche aufweist. Devices for compacting hollow bodies are known from the prior art in various designs. In these devices, a roller often works against an abutment, between these two components there is a pull-in gap for the hollow body to be compacted. From the roller protrude radially catchment elements, which serve on the one hand to improve the collection and on the other hand, the compaction of the hollow body. In most cases, the anvil is another roller. The anvil can also be replaced by a e.g. plate-shaped member may be formed, which has a flat or curved abutment surface.
Beispiele für Vorrichtungen zum Kompaktieren von Hohlkörpern sind in der DE 85 15 290 U1 , DE 201 11 752 U1 , DE 10 2006 036 145 A1 , DE 20 2008 012 248 U1 , DE 101 14 686 C1 , DE 103 25 368 B4, DE 200 23 690 111 und DE 10 2006 033 617 A1 zu finden, Examples of devices for compacting hollow bodies are described in DE 85 15 290 U1, DE 201 11 752 U1, DE 10 2006 036 145 A1, DE 20 2008 012 248 U1, DE 101 14 686 C1, DE 103 25 368 B4, DE 200 23 690 111 and DE 10 2006 033 617 A1,
In der DE 103 25 368 B4 ist eine Kompaktiervorrichtung offenbart, die zwei gegenläufig antreibbare Walzen umfasst, die parallel in einem Abstand zueinander angeordnet und derart ausgebildet sind, dass leere Behälter zwischen ihnen zerschnitten und zusammengedrückt werden. Zu diesem Zweck weist jede Walze mehrere entlang einer Walzenachse hintereinander montiere Scheiben auf. Ein Teil der Scheiben ist als Druckscheibe ausgebildet, der andere Teil der Scheiben als Schneidscheibe. Des Weiteren sind die Walzen derart angeordnet, dass Scheiben der einen Walze in die Zwischenräume zwischen den Scheiben der anderen Walze eingreifen. Durch eine gegenläufige Bewegung der Walzen wird ein leerer Behälter in den Zwischenraum der Walzen gezogen und durch die Vielzahl von Druck- und Schneidscheiben zusammengedrückt und zerschnitten. Dies ermöglicht insbesondere auch das Kompaktieren von leeren, geschlossenen Behältern, ohne dieser vorher perforieren zu müssen. Die Einzugselemente dieser Walzen sind durch die Zähne der Schneidscheiben gebildet, die in Umlaufrichtung der Walzen hakenförmig ausgebildet sind. In DE 103 25 368 B4 a compacting device is disclosed which comprises two counter-drivable rollers, which are arranged in parallel at a distance from each other and designed such that empty containers are cut and compressed between them. To this end For example, each roll has a plurality of disks mounted one behind the other along a roll axis. One part of the disks is designed as a pressure disk, the other part of the disks as a cutting disk. Furthermore, the rollers are arranged such that discs of one roller engage in the spaces between the discs of the other roller. By an opposite movement of the rollers, an empty container is drawn into the space between the rollers and compressed by the plurality of pressure and cutting discs and cut. This allows in particular the compacting of empty, closed containers, without having to perforate this before. The intake elements of these rollers are formed by the teeth of the cutting discs, which are hook-shaped in the direction of rotation of the rollers.
Eine Kompaktiervorrichtung gemäß DE 85 15 290 U1 besitzt ebenfalls ein gegenläufig angetriebenes Walzenpaar, wobei von dem Grundkörper der Walzen als Einzugselemente Stiftelemente radial abragen. A compacting device according to DE 85 15 290 U1 also has a counter-rotating pair of rollers, projecting radially from the main body of the rollers as feeder elements pin elements.
In der DE 200 23 690 U1 wird eine gattungsgemäße Vorrichtung zum Kompaktieren von leeren Getränkebehältern beschrieben. Diese Vorrichtung besitzt eine sich im Wesentlichen trichterförmig verjüngende Förderstrecke, in die die Getränkebehälter einlaufen und unter der Wirkung von die Förderstrecke seitlich begrenzenden Einrichtungen zum Fördern und Zusammenpressen eine sukzessive Kompaktierung erfahren. Dabei bestehen die Einrichtungen zum Fördern und Zusammenpressen der Getränkebehälter aus mit Trommelmotoren angetriebenen Walzen. Als Einzugselemente besitzen diese Walzen mehrere auf ihrem Umfang verteilte, schneidenförmige Erhöhungen, die parallel zueinander ausgerichtet sind und sich über die gesamte Länge der Walzen erstrecken. Anstelle dieser schneidenartigen Erhöhungen können die Walzen auch mit von ihrem Grundkörper abragenden Stiften oder Spikes versehen sein. Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Vorrichtung zum Kompaktieren zur Verfügung zu stellen, die mit Einzugselementen ausgestattet ist, die neben einem effektiven Einzug auch eine effektive Kompaktierarbeit leisten. In DE 200 23 690 U1 a generic device for compacting empty beverage containers is described. This device has a substantially funnel-shaped tapered conveyor line, in which run the beverage containers and undergo a successive compaction under the action of the conveying path laterally limiting means for conveying and compressing. In this case, the means for conveying and compressing the beverage container from driven with drum motors rollers. As feeder elements, these rollers have a plurality of circumferentially distributed, blade-shaped elevations which are aligned parallel to each other and extend over the entire length of the rollers. Instead of these blade-like elevations, the rollers can also be provided with protruding from their base pins or spikes. Object of the present invention is to provide a generic device for compacting available, which is equipped with feeder elements, which also perform an effective Kompaktierarbeit in addition to an effective feeder.
Diese Aufgabe wird erfindungsgemäß mit einer Vorrichtung gelöst, die die Merkmale des Anspruchs 1 aufweist. This object is achieved with a device having the features of claim 1.
Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unter- ansprüche. Advantageous developments of the invention are the subject of the subclaims.
Es hat sich überraschender Weise gezeigt, dass gattungsgemäße Vorrichtungen, bei denen die Einzugselemente durch Leisten gebildet sind, die von einem geradlinigen Verlauf abweichen, nämlich wellenförmig verlaufen, mit einem sehr effektiven Einzug der zu verdichtenden Hohlkörper in den Einzugsspalt zwischen der Walze und ihrem Gegenlager arbeiten. Darüber hinaus verlassen im Ergebnis stark kompaktierte Hohlkörper die erfindungsgemäße Vorrichtung. Als besonders effektiv im oben genannten Sinne haben sich Einzugselemente herausgestellt, die durch zickzackförmig verlaufende Leisten gebildet sind. It has surprisingly been found that generic devices in which the catchment elements are formed by strips that deviate from a straight course, namely wavy, work with a very effective collection of the hollow body to be compacted in the nip between the roller and its abutment , In addition, as a result, highly compacted hollow bodies leave the device according to the invention. Induction elements which have been formed by zigzag-shaped strips have proven to be particularly effective in the above-mentioned sense.
Die Walze einer erfindungsgemäßen Vorrichtung arbeitet gegen ein Gegenlager. Dieses kann z. B. eine ebene oder gewölbte Widerlagerfläche eines plattenförmigen Bauteils sein. Bevorzugt ist jedoch, dass das Gegenlager eine zweite, parallel zur ersten Walze ausgerichtete Walze ist, die zudem in bevorzugter Weise identisch mit der ersten Walze ausgebildet ist. Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert. In der dazugehörigen Zeichnung zeigt: Fig. 1 eine schematische Seitenansicht einer erfindungsgemäßen Vorrichtung, The roller of a device according to the invention works against an abutment. This can be z. B. be a flat or curved abutment surface of a plate-shaped component. However, it is preferred that the abutment is a second, aligned parallel to the first roller roller, which is also preferably formed identical to the first roller. The invention will be explained in more detail below with reference to an embodiment. In the accompanying drawing shows: 1 is a schematic side view of a device according to the invention,

Die in der Zeichnung dargestellte Vorrichtung 1 dient der Kompaktie- rung von Getränkeblechdosen. Sie weist ein Gehäuse 2 auf, welches zwei parallel zueinander angeordnete Walzen 3 und 4 sowie ein Zuführflügelrad 5 aufnimmt. Außen am Gehäuse 2 ist ein Elektromotor 6 angeordnet, der über nicht dargestellte Zahnräder und Antriebsketten die beiden Walzen 3 und 4 gegenläufig in Richtung der Pfeile 7 und 8 sowie das Zuführflügelrad 5 in Richtung des Pfeiles 9, also in Gegenuhrzeigerrichtung, antreibt. Zwischen den beiden Walzen 3 und 4 besteht ein Einzugsspalt 23. The apparatus 1 shown in the drawing is used for compacting beverage tin cans. It has a housing 2 which accommodates two rollers 3 and 4 arranged parallel to one another and a feed impeller 5. Outside the housing 2, an electric motor 6 is arranged, the not shown gears and drive chains, the two rollers 3 and 4 in opposite directions in the direction of arrows 7 and 8 and the Zuführflügelrad 5 in the direction of arrow 9, ie in the counterclockwise direction, drives. Between the two rollers 3 and 4 there is a pull-in gap 23rd
Die Walzen 3, 4 besitzen einen zylindrischen Grundkörper 10, von dessen Enden beidseitig zentrisch Lager- und Antriebszapfen 11 axial abragen. Vom Grundkörper 10 der Walzen 3, 4 ragt weiterhin eine Vielzahl von parallel zueinander ausgerichteten Leisten 12 radial ab. Die Leisten 12 haben eine Zickzackform und erstrecken sich in Längsrichtung der Walzen 3, 4 über deren gesamter Länge. The rollers 3, 4 have a cylindrical base body 10, from the ends of both sides centric bearing and drive pin 11 protrude axially. From the main body 10 of the rollers 3, 4 further projects a plurality of parallel aligned strips 12 radially from. The strips 12 have a zigzag shape and extend in the longitudinal direction of the rollers 3, 4 over their entire length.
Die Walzen 3, 4 bestehen aus Metall und sind durch spanende Formgebung hergestellt. In diesem Herstellungsprozess wird zunächst ein Vollzy- linder mit dem Durchmesser d ( s. Fig. 4) gedreht, von dem anschließend die Lager- und Antriebszapfen 11 beidseitig abgedreht werden. Die Herstellung der Leisten 12 erfolgt durch Fräsen aus dem zuvor gedrehten Vollzylinder. An dieser Stelle sei erwähnt, dass der Einzugsspalt 23 zwischen den Durchmessern d der Walzen 3 und 4 gebildet ist, d.h., die Leisten 12 der beiden Walzen 3 und 4 kämmen nicht miteinander. In diesem Ausführungsbeispiel beträgt der Einzugsspalt 23 1 ,5 mm bei einem Durchmesser d der Walzen 3 und 4 von 63 mm. The rollers 3, 4 are made of metal and are produced by machining. In this production process, first a full cylinder with the diameter d (see Fig. 4) is rotated, from which subsequently the bearing and drive pins 11 are turned off on both sides. The production the last 12 is made by milling from the previously rotated solid cylinder. At this point it should be mentioned that the pull-in gap 23 is formed between the diameters d of the rollers 3 and 4, ie, the strips 12 of the two rollers 3 and 4 do not mesh with each other. In this embodiment, the pull-in gap 23 1, 5 mm at a diameter d of the rollers 3 and 4 of 63 mm.
Wie aus den Fig. 3 und 4 hervorgeht, haben die Leisten 12 die Form eines symmetrischen Trapezes, d.h., die beiden Seitenflanken 13 und 14 jeder Leiste 12 haben einen gleichen Neigungswinkel und verjüngen sich nach außen, wo sie in eine Kopffläche 15 auslaufen, die auf dem Durchmesser d liegt und somit aufgrund ihrer geringen Erstreckung in Umfangsrichtung im Wesentlichen eben ist, wobei die Übergänge von den Seitenflanken 13 und 14 zu der Kopffläche 15 scharfkantig sind. Die Leisten 12 sind gleichmäßig verteilt auf dem Umfang der Walzen 3 und 4 angeordnet. Nach der spanenden Bearbeitung der Walzen 3 und 4 werden diese abschließend oberflächengehärtet. As is apparent from Figs. 3 and 4, the strips 12 have the shape of a symmetrical trapezium, ie, the two side edges 13 and 14 of each bar 12 have a same angle of inclination and taper outward, where they leak into a head surface 15, the is on the diameter d and thus substantially flat due to their small extent in the circumferential direction, wherein the transitions from the side edges 13 and 14 to the top surface 15 are sharp-edged. The strips 12 are evenly distributed on the circumference of the rollers 3 and 4 are arranged. After the machining of the rollers 3 and 4, these are finally surface-hardened.
Das Zuführflügelrad 5 besitzt eine zentrale Welle 16, über die es beid- seitig am Gehäuse 2 drehbar gelagert ist. Drehfest verbunden mit der Welle 16 sind beidseitig an deren Endbereichen angeordnete Flansche 17, an denen drei jeweils im Abstand von ca. 120° angeordnete Flügel 18 befestigt sind. Diese Flügel 18 bestehen aus abgekanteten Blechen. Das Zuführflügelrad 5 dient zum einen der Zufuhr der zu kompaktierenden Getränkedosen zu den Walzen 3 und 4 und, in Zusammenwirken mit einem Retourblech 19, der Rückführung von zunächst nicht kompaktieren Getränkedosen zu den Walzen 3 und 4, was weiter unten näher beschrieben wird. Das Retourblech 19 ist konzentrisch zur Welle 16 des Zuführflügelrades 5 angeordnet und besitzt einen etwas größeren Durchmesser als der Durchmesser der Flügel 18. Es erstreckt sich von einem Bereich angrenzend an die Walze 4 bis zu einem Bereich oberhalb der Welle 16 des Zuführflügelrades 5. Ebenfalls im Gehäuse 2 angeordnet ist ein Zuführblech 20, welches mit seinem einen Ende am Gehäuse 2 befestigt ist und schräg nach unten bis in die Nähe der Walze 3 geführt ist. Das Retourblech 19 und das Zuführblech 20 erstrecken sich im Wesentlichen über die gesamte Länge der Walzen 3 und 4. Aus Übersichtgründen sind das Zuführblech 20, das Retourblech 19 sowie ein Flügel 18 des Zuführflügelrades 5 in Fig. 2 weggelassen worden. The Zuführflügelrad 5 has a central shaft 16, via which it is rotatably mounted on both sides of the housing 2. Rotationally connected to the shaft 16 are arranged on both sides at their end portions flanges 17, to which three each arranged at a distance of about 120 ° wings 18 are attached. These wings 18 consist of folded sheets. The Zuführflügelrad 5 serves for a supply of the compacted to beverage cans to the rollers 3 and 4 and, in cooperation with a return plate 19, the return of initially non-compacted beverage cans to the rollers 3 and 4, which will be described in more detail below. The return plate 19 is arranged concentrically with the shaft 16 of the Zuführflügelrades 5 and has a slightly larger diameter than the diameter of the wings 18. It extends from a region adjacent to the roller 4 to an area above the shaft 16 of the Zuführflügelrades. 5 Also arranged in the housing 2 is a feed plate 20, which is fastened with its one end to the housing 2 and is guided obliquely downwards to the vicinity of the roller 3. The return plate 19 and the feed plate 20 extend substantially over the entire length of the rollers 3 and 4. For reasons of clarity, the feed plate 20, the return plate 19 and a wing 18 of the Zuführflügelrades 5 have been omitted in Fig. 2.
Das Gehäuse 2 ist an seinem oberen Ende mit einer Eingabeöffnung 21 und an seinem unteren Ende mit einer Ausgabeöffnung 22 versehen, die in der Zeichnung nur symbolisch dargestellt sind. The housing 2 is provided at its upper end with an input port 21 and at its lower end with a discharge opening 22, which are shown only symbolically in the drawing.
Die Arbeitsweise der oben beschriebenen Vorrichtung 1 wird nachstehend näher erläutert. The operation of the device 1 described above will be explained in more detail below.
In die Vorrichtung 1 über die Eingabeöffnung 21 eingegebene Getränkedosen gelangen unter Schwerkraftwirkung über das Zuführblech 20 in den Bereich der beiden Walzen 3 und 4. Da diese sich in Richtung der Pfeile 7 bzw. 8 gegenläufig bewegen, werden die Getränkedosen in den zwischen den beiden Walzen 3 und 4 gebildeten Einzugsspalt 23 eingezogen. Dieser Einzug wird durch das Zuführflügelrad 5 unterstützt. Die Enden 24 der Flügel 18 sind so abgewinkelt, dass sie im Bereich der Walzen 3, 4 einen Druck auf die Getränkedosen ausüben, der in Richtung des Einzugsspalts 23 gerichtet ist. Im Einzugsspalt 23 werden die eingezogenen Getränkedosen platt gedrückt und gleichzeitig aufgrund der scharfkantigen Übergänge zwischen den Seitenflanken 13, 14 und den Kopfflächen 15 der Leisten 12 eingeschnitten, so dass Pfandlogos oder ähnliche Sicherheitskennzeichen zerstört werden, um einen Missbrauch zu verhindern. In the device 1 via the input port 21 entered beverage cans reach under gravity through the feed plate 20 in the region of the two rollers 3 and 4. Since these move in the direction of the arrows 7 and 8 in opposite directions, the beverage cans in between the two rolls 3 and 4 formed feed nip 23 retracted. This intake is supported by the Zuführflügelrad 5. The ends 24 of the wings 18 are angled so that they exert pressure in the region of the rollers 3, 4 on the beverage cans, which is directed in the direction of the intake gap 23. In the nip 23, the drawn beverage cans are flattened and simultaneously cut due to the sharp-edged transitions between the side edges 13, 14 and the top surfaces 15 of the strips 12 so that pledge logos or similar security marks are destroyed to prevent misuse.
Die zwischen den Walzen 3, 4 platt gedrückten Getränkedosen fallen unten durch die Ausgabeöffnung 22 in einen nicht dargestellten Sammelbe- hälter. Im ersten Anlauf nicht zwischen die Walzen 3 und 4 eingezogene Getränkedosen werden von den Flügeln 18 des Zuführflügelrades 5 mitgenommen und von diesen am Retourblech 19 entlang geführt, so dass sie schließlich über das Zuführblech 20 wieder in den Bereich der Walzen 3 und 4 gelangen. The flat pressed between the rollers 3, 4 beverage cans fall down through the discharge opening 22 in a collection, not shown. container. Beverage cans not drawn in between the rollers 3 and 4 during the first start are taken along by the wings 18 of the feed impeller 5 and guided along them on the return plate 19, so that they finally return to the area of the rollers 3 and 4 via the feed plate 20.
