Es ist eine Einrichtung zur Erzeugung von Streifen aus Kunststoff, z.B. Kunststoffplatten aus geschäumtem Kunststoff, also z.B. Schaumstoff bekannt. Diese Einrichtung besteht aus zwei einander gegenüberliegend an einem Rahmen angebrachten drehbaren Wellen, die mehrere senkrecht stehende Kreismesser aufweisen. Mit Hilfe dieser Einrichtung ist es möglich aus Schaumstoffplatten Streifen herzustellen. Diese Streifen werden von einem dieser Schneideinrichtung nachgeordneten Transportband zu einer sogenannten Schneidmühle gefördert. Derartige Schneidmühlen sind bekannt. Sie sind unter dem Gesichtspunkt des Umweltschutzes äußerst bedenklich, da sie laut sind und zum Betrieb einen hohen Energiebedarf erfordern; auch ist bei der Zerkleinerung der Kunststoffstreifen eine hohe Staubentwicklung festzustellen. Derartiger Staub kann nicht verarbeitet werden, sondern muß als nichtverwertbarer Abfall behandelt werden und belastet somit die Mülldeponien. Ein weiterer wesentlicher Nachteil besteht darin, daß mit einer derartigen Schneidmühle keine vorher bestimmbare einheitliche Größe der Schaumstoffstücke, seien es Stäbchen oder Würfel, erzeugt werden kann. It is a device for producing strips Plastic, e.g. Foam plastic sheets Plastic, e.g. Foam known. This facility consists of two opposite each other on a frame attached rotatable shafts that have several vertical Have circular knives. With the help of this facility it is possible to produce strips from foam sheets. These Strips are made by one of these cutters downstream conveyor belt to a so-called Cutting mill promoted. Such cutting mills are known. They are extreme from an environmental point of view questionable because they are noisy and high for operation Require energy; is also the size reduction Plastic strips detect a high level of dust. Such dust cannot be processed, but must be treated as non-recyclable waste and contaminated thus the landfills. Another major disadvantage is that with such a cutting mill none predeterminable uniform size of the foam pieces, be it chopsticks or cubes.  

Dies beruht im wesentlichen darauf, daß die in der Schneidmühle befindlichen Schaumstoffteilchen oder Schaumstoffstücke so lange bearbeitet werden, bis sie durch ein in der Schneidmühle eingesetztes Sieb fallen.This is mainly due to the fact that the Cutting foam foam or Pieces of foam are processed until they are through a sieve inserted in the granulator falls.

Zur Vermeidung dieser Nachteile, besteht die erfindungsgemäße Vorrichtung zum Zerkleinern von Kunststoffteilen, insbesondere geschäumtem Kunststoff, wie z.B. Schaumstoff, die die nach dem Stand der Technik bekannte Schneidmühle ersetzen soll, aus einer rotierenden Halterung, die ein umlaufendes Messerband aufweist. Die rotierende Halterung, die beispielsweise in Form einer Welle ausgebildet sein kann, weist im einzelnen zwei drehbare Achsen zur Aufnahme des Messerbandes auf, wobei mindestens eine Achse einen Antrieb für das Messerband besitzt. Nach einer vorteilhaften Ausführungsform ist der Abstand zwischen den beiden Achsen veränderbar, wodurch das Einspannen des Messerbandes bzw. das Nachspannen ermöglicht wird.To avoid these disadvantages, there is the inventive Device for crushing plastic parts, in particular foamed plastic, such as Foam that the after Known prior art is intended to replace a cutting mill a rotating holder that has a revolving knife belt having. The rotating bracket, for example in The shape of a wave can be configured in detail two rotatable axes for receiving the knife band, whereby at least one axis drives the knife belt owns. According to an advantageous embodiment, the Distance between the two axes can be changed, which means that Clamping the knife band or re-tensioning allows becomes.

Nach einer weiteren vorteilhaften Ausführungsform wird die Halterung durch einen Antrieb in Rotation versetzt, der rechts- und linksläufig ausgebildet ist, so daß bei Einsatz eines beidseitig angeschliffenen Messerbandes eine erhöhte Standzeit der Vorrichtung erreicht wird.According to a further advantageous embodiment, the Bracket set in rotation by a drive which is formed clockwise and counterclockwise, so that when used of a knife belt ground on both sides increased Tool life is reached.

Gegenstand der Erfindung ist auch der Anbau der Vorrichtung zur Zerkleinerung von Kunststoffteilen, insbesondere Kunststoff, wie z.B. Schaumstoff an eine Einrichtung zur Erzeugung von Streifen aus Kunststoff, die, wie eingangs beschrieben, aus zwei an einem Rahmen einander gegenüberliegend angeordneter sich gegenläufig drehender Wellen besteht, die jeweils mehrere parallel zueinander angeordnete Kreismesser aufweisen. The invention also relates to the mounting of the device for shredding plastic parts, in particular Plastic, e.g. Foam to a device for Production of strips of plastic, which, as at the beginning described, two from each other on a frame oppositely arranged, rotating in opposite directions Waves exist, each several parallel to each other have arranged circular knives.  

Dieser Schneideinrichtung nachgeordnet ist ein Transportband, an das sich die erfindungsgemäße Vorrichtung zum Zerkleinern von Kunststoffteilen anschließt.A conveyor belt is arranged downstream of this cutting device, to which the inventive device for crushing of plastic parts.

In der Zeichnung ist eine beispielsweise Ausführungsform dargestellt.In the drawing is an example embodiment shown.

Die Zeichnung zeigt die gesamte Vorrichtung in einer Draufsicht. Die Vorrichtung selbst besteht aus einem insgesamt mit 1 bezeichneten Rahmen, der eine Schneideinrichtung 2 aufweist, die aus zwei einander gegenüberliegend angeordneten rotierenden Wellen 3, 4 besteht, die jeweils mit mehreren parallel zueinander angeordneten Kreismessern 5, 6 versehen sind. Mit Hilfe dieser Schneideinrichtung werden beispielsweise in Richtung des Pfeiles X eingeführte Kunststoffplatten zu Streifen zerschnitten. Diese Streifen werden von einem dieser Schneideinrichtung 2 nachgeordneten Transportband 7 aufgenommen und der erfindungsgemäßen Vorrichtung zur Zerkleinerung von Kunststoffteilen, insbesondere geschäumten Kunststoff, wie z.B. Schaumstoff zugeführt. Diese mit 8 bezeichnete Vorrichtung besteht aus einer drehbar im Rahmen 1 gelagerten Halterung 9, in Form beispielsweise einer Welle, die zwei mit Abstand zueinander angeordnete Achsen 10 und 11 aufweist, die jeweils ein Rad 12, 13 zur Aufnahme des Messerbandes 14 besitzen. Die Achse 11, die durch den Motor 15 angetrieben wird, ist von der Achse 9 in einem Langloch 16 längsverschieblich gehalten, so daß der Abstand zwischen den beiden Achsen 10 und 11 veränderbar ist. Hierdurch wird das Einspannen des Messerbandes 14 erleichtert bzw. dessen Nachspannen ermöglicht. The drawing shows the entire device in a plan view. The device itself consists of a frame, generally designated 1 , which has a cutting device 2 , which consists of two rotating shafts 3, 4 arranged opposite one another, each of which is provided with a plurality of circular knives 5 , 6 arranged parallel to one another. With the help of this cutting device, for example, plastic plates inserted in the direction of the arrow X are cut into strips. These strips are picked up by a conveyor belt 7 arranged downstream of this cutting device 2 and fed to the device according to the invention for comminuting plastic parts, in particular foamed plastic, such as foam. This designated 8 device consists of a rotatably mounted in the frame 1 bracket 9 , for example in the form of a shaft which has two spaced axes 10 and 11 , each having a wheel 12 , 13 for receiving the knife belt 14 .
