Description

Kompaktiervorrichtung compactor

Die Erfindung betrifft eine Kompaktiervorrichtung zum Kompaktieren leerer Behälter, insbesondere Getränkeflaschen oder -dosen aus Kunststoff oder Blech, wie Weißblech oder Aluminiumblech.The invention relates to a compacting device for compacting empty containers, in particular beverage bottles or cans made of plastic or sheet metal, such as tinplate or aluminum sheet.

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 mon- tierte 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 Zwi- schenraum der Walzen gezogen und durch die Vielzahl an Druck- undIn 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. For this purpose, each roller has a plurality of disks mounted successively 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 pulled into the interspace of the rollers and by the large number of pressure and

Schneidscheiben zusammengedrückt und zerschnitten. Dies ermöglicht insbesondere auch das Kompaktieren von leeren, geschlossenen Behältern, ohne diese vorher perforieren zu müssen.Cutting discs compressed and cut. This allows in particular the compacting of empty, closed containers without having to perforate them before.

In der DE 85 15 290 U1 ist eine gattungsgemäße Kompaktiervorrichtung beschrieben. Diese Vorrichtung besitzt mindestens eine Walze zum Zusammendrücken und Perforieren von leeren Behältern, wobei von dem Grundkörper der Walze Stiftelemente radial abragen. Die Stiftelemente sind in Aufnahmen des Walzengrundkörpers mit Presssitz eingeschlagen und mit- tels eines Metallklebers darin befestigt. Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Kom- paktiervorrichtung zur Verfügung zu stellen, mit der bei einfachem Aufbau auf sehr effektive Weise eine Kompaktierung von leeren Behältern erreicht werden kann.In DE 85 15 290 U1 a generic compacting device is described. This device has at least one roller for compressing and perforating empty containers, wherein protrude from the main body of the roller pin elements radially. The pin elements are hammered into receptacles of the roll base body and fastened therein by means of a metal adhesive. Object of the present invention is to provide a generic compact paktiervorrichtung available, with a simple structure in a very effective way, a compaction of empty containers can be achieved.

Diese Aufgabe wird durch eine Kompaktiervorrichtung gemäß Anspruch 1 gelöst.This object is achieved by a compacting apparatus according to claim 1.

Vorteilhafte Weiterbildungen sind Gegenstände der abhängigen An- sprüche.Advantageous developments are subject matter of the dependent claims.

Die erfindungsgemäße Kompaktiervorrichtung zum Kompaktieren leerer Behälter, insbesondere Getränkeflaschen oder -dosen aus Kunststoff oder Weißblech, ist dadurch gekennzeichnet, dass das mindestens eine Stiftele- ment als Hohlstift ausgeführt ist, wobei zumindest die vom Walzengrundkörper wegweisende Stirnfläche des Hohlstiftes offen ist.The compacting device according to the invention for compacting empty containers, in particular beverage bottles or cans made of plastic or tinplate, is characterized in that the at least one pin element is designed as a hollow pin, wherein at least the end face of the hollow pin facing away from the roller body is open.

Ein derartig aufgebautes Stiftelement ermöglicht es, neben einem bloßen Zusammendrücken eines Behälters im selben Vorgang auch eine Perfo- ration des Behälters zu erzielen. Vorzugsweise sind hierfür eine Vielzahl von Stiftelementen am Walzengrundkörper angeordnet. Des Weiteren begünstigt ein derartiges abstehendes Stiftelement den Einzug eines Behälters, beispielsweise in dem das Stiftelement unebene Bereiche des Behälters hintergreift und auf diese Weise den Behälter mitführt.A pin element constructed in this way makes it possible to achieve not only a mere compression of a container in the same process, but also a perforation of the container. Preferably, a plurality of pin elements are arranged on the roller base body for this purpose. Furthermore, such a projecting pin element favors the collection of a container, for example, in which the pin element engages behind uneven areas of the container and in this way carries the container.

In vorteilhafter Ausgestaltung der Erfindung weist der Walzengrundkörper eine Aufnahme auf, in die das mindestens eine Stiftelement kraftschlüssig eingesetzt ist. Durch das kraftschlüssige Einsetzen des Stiftelements in den Walzengrundkörper ist zum einen gesichert, dass bei einer Beschädi- gung oder Abnutzung einzelner Stiftelemente die betroffenen Stiftelemente auswechselbar sind. Ein Austausch des Walzengrundkörpers, insbesondere auch eine Demontage des Walzengrundkörpers, wie beim Stand der Technik erforderlich, kann entfallen. Zum anderen gewährleistet die kraftschlüssige Verbindung zwischen dem Stiftelemente und dem Walzengrundkörper auch, dass dieses den beim Zusammendrücken und Perforieren von Behältern wir- kenden Kräften standhält, ohne sich vom Walzengrundkörper zu lösen.In an advantageous embodiment of the invention, the roller base body has a receptacle into which the at least one pin element is non-positively inserted. Due to the frictional insertion of the pin element into the roller base body, it is ensured on the one hand that the affected pin elements can be exchanged in the event of damage or wear of individual pin elements. An exchange of the roller body, in particular Disassembly of the roller body, as required in the prior art, can be omitted. On the other hand, the frictional connection between the pin elements and the roll base body also ensures that it withstands the forces acting on the compression and perforation of containers without becoming detached from the roll base body.

In besonders vorteilhafter Weiterbildung der Erfindung werden als Hohlstifte Spiralspannstifte eingesetzt. Aufgrund ihrer radial-elastischen Eigenschaften ist gewährleistet, dass sich die Spiralspannstifte unter Belastungen, wie sie beim Betrieb der Kompaktiervorrichtung auftreten, nicht vom Walzengrundkörper lösen. Zum Auswechseln verschlissener Spiralspannstifte können diese einfach radial aus der Aufnahme im Walzengrundkörper herausgezogen werden, indem sie zuvor radial gestaucht wurden.In a particularly advantageous embodiment of the invention are used as hollow pins Spiralspannstifte. Due to their radial-elastic properties, it is ensured that the spiral tension pins do not come loose from the roller body under loads which occur during operation of the compacting device. To replace worn Spiralspannstifte these can simply be pulled radially out of the receptacle in the roll body by previously compressed radially.

Dadurch, dass das mindestens eine Stiftelement vom Walzengrundkörper absteht, wird der Walzengrundkörper geringer belastet. Dies ist insbesondere dann der Fall, wenn eine Vielzahl von Stiftelementen gleichmäßig am Walzengrundkörper angeordnet ist. Dies ermöglicht es für die Ausbildung des Walzengrundköpers weniger stark belastbare Materialien zu verwenden, beispielsweise einen kostengünstigen Kunststoff. Beispielsweise kann der Walzengrundkörper als ein einstückiges Kunststoff-Spritzgussteil hergestellt werden.Due to the fact that the at least one pin element protrudes from the roller base body, the roller base body is loaded less. This is the case in particular when a plurality of pin elements is arranged uniformly on the roll base body. This makes it possible to use less strong materials for the formation of the Walzengrundköpers, for example, a low-cost plastic. For example, the roll base body can be produced as a one-piece plastic injection-molded part.

Ein erster Abschnitt 6 weist jeweils mehrere solcher Aufnahmen 4 auf, die umlaufend der Walzenachse 8a, 8b gleichmäßig versetzt angeordnet sind. Bezüglich benachbarten ersten Abschnitten 6 ist ein derartiger Satz von Aufnahmen 4 um einen bestimmten Winkel versetzt, hier 15 Grad, wodurch sich eine spiralförmige Anordnung der Aufnahmen 4 entlang der Walzenachsen 8a, 8b ergibt.The first roller base body 2a and the second roller base body 2b have a substantially cylindrical shape. Further, the roller base bodies 2a, 2b are subdivided into first disc-shaped sections 6 and second disc-shaped sections 7. The first sections and the second sections 7 are arranged alternately one behind the other along a respective roller axis 8a, 8b. The roll axes 8a, 8b correspond to the axes of the shafts 22a and 22b, respectively. A first section 6 is formed with a larger diameter than a second section 7. The width of the first sections 6 and the second sections 7 are the same. In the first sections 6 receptacles 4 are formed for the reception of pin elements 3. The second sections 7 are free of such receptacles 4. A receptacle 4 is formed by a cylindrical recess in the form of a blind hole, which is aligned radially outward facing the roller axis 8a and 8b. A first section 6 has in each case a plurality of such receptacles 4, which are arranged offset uniformly circumferentially of the roll axis 8a, 8b. With respect to adjacent first sections 6, such a set of receptacles 4 is offset by a certain angle, here 15 degrees, resulting in a spiral arrangement of the receptacles 4 along the roller axes 8a, 8b.

Bis auf die ersten Abschnitte 6, die sich am jeweiligen Ende des Walzengrundkörpers 2a, 2b befinden, sind in sämtlichen Aufnahmen 4 Stiftelemente 3 eingesetzt. Die Tiefe der Aufnahmen 4 und der Durchmesser der Aufnahmen 4 sind an die entsprechenden Abmessungen der Stiftelemente 3 angepasst, so dass ein Stiftelement 3 kraftschlüssig in eine Aufnahme 4 einsetzbar ist und mit einem Endabschnitt über die Aufnahme 4 hinaussteht.Except for the first sections 6, which are located at the respective end of the roller body 2a, 2b, 4 pin elements 3 are used in all recordings. The depth of the receptacles 4 and the diameter of the receptacles 4 are adapted to the corresponding dimensions of the pin elements 3, so that a pin member 3 is non-positively inserted into a receptacle 4 and protrudes with an end portion on the receptacle 4.

Die erste Walze 1a und die zweite Walze 1b sind derart voneinander beabstandet, dass die Stiftelemente 3 der ersten Walze 1a in die Zwischenbereiche 9 zwischen zwei ersten Abschnitten 6 der zweiten Walze 1b und die Stiftelemente 3 der zweiten Walze 1b in die Zwischenbereiche 9 zwischen zwei ersten Abschnitten 6 der ersten Walze 1a eingreifen.The first roller 1a and the second roller 1b are spaced apart such that the pin elements 3 of the first roller 1a in the intermediate regions 9 between two first portions 6 of the second roller 1b and the pin elements 3 of the second roller 1b in the intermediate regions 9 between two first Engage sections 6 of the first roller 1a.

Als Stiftelement 3 wird ein handelsüblicher Spiralspannstift 3 verwendet,As a pin element 3, a commercially available spiral tension pin 3 is used,

(siehe Figuren 3a bis 3c). Der Spiralspannstift 3 besteht aus einem spiralförmig aufgewickeltem elastischen Blech, vorzugsweise einem Federblech, der, um das Einsetzen in eine Aufnahme 4 zu erleichtern an einem Ende eine konisch geformte Schräge 23 aufweist. Im montierten Zustand, siehe Figur 3b, ist der Spiralspannstift 3 zusammengedrückt und steht damit radial unter Spannung. Aufgrund dieser radialen Spannung kann ein effektiver Kraft- schluss mit dem Walzengrundkörper 2a, 2b erreicht werden. Unter Belastung im eingesetzten Zustand, siehe Figur 3c, kann sich der Spiralstift 3 weiter verformen. Ein Spiralspannstift 3 hat hier einen Durchmesser im Bereich von 5 bis 10 mm, vorzugsweise etwa 8 mm, und eine Länge im Bereich von 12 bis 30 mm, vorzugsweise etwa 21 mm.(see Figures 3a to 3c). The spiral tension pin 3 consists of a spirally wound elastic sheet metal, preferably a spring plate, which, in order to facilitate insertion into a receptacle 4 has at one end a conically shaped bevel 23. In the assembled state, see Figure 3b, the spiral tension pin 3 is compressed and is thus radially under tension. Due to this radial stress, an effective force conclusion can be achieved with the roller body 2a, 2b. Under load in the inserted state, see Figure 3c, the spiral pin 3 can deform further. A spiral tension pin 3 here has a diameter in the range of 5 to 10 mm, preferably about 8 mm, and a length in the range of 12 to 30 mm, preferably about 21 mm.

Die Antriebsvorrichtung 10, die in diesem Ausführungsbeispiel ein Elektromotor ist, ist über nicht dargestellte Zahnräder und Antriebsketten mit den Wellen 22a, 22b der Walzen 1a, 1b und der Paddelwelle 19 zu deren Antrieb verbunden. Im Betrieb führen die Walzen 1a, 1b eine gegenläufige Rotationsbewegung aus, wobei sich die erste Welle 1a im Uhrzeigersinn und die zweite Welle 1b gegen den Uhrzeigersinn dreht. Die Paddelwelle 19 und damit die Paddel 18 drehen sich gegen den Uhrzeigersinn.The drive device 10, which is an electric motor in this embodiment, is connected via not shown gears and drive chains with the shafts 22a, 22b of the rollers 1a, 1b and the paddle shaft 19 to the drive. In operation, the rollers 1a, 1b rotate in opposite directions, with the first shaft 1a rotating clockwise and the second shaft 1b rotating counterclockwise. The paddle shaft 19 and thus the paddle 18 rotate counterclockwise.

Ein leerer Behälter, der über die Eingangsöffnung 11 oder über dasAn empty container, via the inlet opening 11 or over the

Rückführblech 21 in den Bereich der Walzen 1a, 1b gelangt, wird durch die sich gegenläufig drehenden Walzen 1a, 1b in den Zwischenbereich der Walzen 1a, 1b eingezogen. Dieser Einzug wird durch die sich drehenden Paddeln 18 unterstützt, die einen leeren Behälter zusätzlich gegen die Walzen 1a, 1b pressen. Des Weiteren wird der Einzug durch die vom Walzengrundkörper 2a, 2b abstehenden Stiftelemente 3, die spiralförmig versetzt angeordnet sind, unterstützt. Im Regelfall wird der leere Behälter durch die Walzen 1a, 1b eingezogen und durch die Stiftelemente 3 und die Walzengrundkörper 2a, 2b perforiert und zusammengedrückt. Der auf diese Weise kom- paktierte Behälter wird über die Ausgangsöffnung 12 ausgegeben. Im Falle eines Nichteinzuges wird ein leerer Behälter über das Rückführblech 21 und die sich drehenden Paddel 18 erneut den Walzen 1a, 1b zugeführt.Return plate 21 passes into the region of the rollers 1a, 1b is fed by the counter-rotating rollers 1a, 1b in the intermediate region of the rollers 1a, 1b. This intake is assisted by the rotating paddles 18, which additionally press an empty container against the rollers 1a, 1b. Furthermore, the feeder is supported by the pin base elements 2a, 2b projecting from the roller body 2a, which are arranged offset in a spiral. As a rule, the empty container is drawn in by the rollers 1a, 1b and perforated and compressed by the pin elements 3 and the roller base bodies 2a, 2b. The container compacted in this way is discharged via the outlet opening 12. In the case of non-take-in, an empty container is fed again to the rollers 1a, 1b via the return plate 21 and the rotating paddles 18.

Es kann eine Abstreifvorrichtung vorgesehen sein, um das Abstreifen eines kompaktierten Behälters von den Walzen 1a, 1b zu unterstützen. Die Walzengrundkörper 2a, 2b sind hier als einstückige Kunststoff- Spritzgußteile ausgebildet. Alternativ ist beispielsweise auch die Verwendung eines Walzengrundkörpers aus Metall möglich. A stripping device may be provided to assist in stripping a compacted container from the rollers 1a, 1b. The roller base body 2a, 2b are formed here as one-piece plastic injection molded parts. Alternatively, for example, the use of a metal roll body is possible.
