Description
Technisches Gebiet:Technical area:
Die Erfindung betrifft eine Vorrichtung zum Aufschneiden und Entfernen von Etiketten an PET-Getränkeflaschen.The invention relates to a device for cutting and removing labels on PET beverage bottles.
Stand der Technik:State of the art:
Nach dem bekannten Stand der Technik werden die entleerten PET-Getränkeflaschen über Sammelstationen eingesammelt und in zentralen Aufbereitungsanlagen recycelt. Dabei werden die Flaschen in einem Schritt mit den Etiketten und den Verschlüssen zerkleinert. Das erfolgt in sogenannten Schreddern.According to the known state of the art, the emptied PET beverage bottles are collected via collecting stations and recycled in central processing plants. The bottles are shredded in one step with the labels and caps. This is done in so-called shredding.
Die verwendeten Flaschen bestehen aber aus unterschiedlichem Material. Der Flaschenkörper besteht aus PET (Polyethylenterephthalat), der Verschluss besteht in der Regel aus Polypropylen (PP) oder einem ähnlichen Kunststoff und die Etiketten sind aus Folienmaterial, meist HDPE-Material und bedruckt, teils aufgeschrumpft oder aufgeklebt, auf dem Flaschenkörper. Nach dem Schreddern der Flaschen erhält man einen Mix aus verschiedenen Materialien.However, the bottles used are made of different materials. The bottle body is made of PET (polyethylene terephthalate), the closure is usually made of polypropylene (PP) or similar plastic and the labels are made of film material, mostly HDPE material and printed, partly shrunk or glued, on the bottle body. After shredding the bottles you get a mix of different materials.
Der so erhaltene Mix aus verschiedensten Materialien muss nun in einem aufwändigen Verfahren getrennt werden. Dabei gelingt es nicht immer, die erforderliche Reinheit des Materiales zu erhalten, die zur Herstellung neuer Flaschen aus dem recycelten Material erforderlich ist.The resulting mix of different materials now has to be separated in a complex process. It is not always possible to obtain the required purity of the material required to make new bottles from the recycled material.
Zur Lösung dieser Probleme sind bereits einige Verfahren bekannt. In der Patentschrift
Die oben genannten Verfahren haben jedoch Nachteile. Zum einen sind sie für die Großindustrielle Anwendung konzipiert und haben deshalb den Nachteil, dass sie sehr umfangreich, technisch sehr aufwendig und damit teuer sind. Zum andern sind sie nicht für eine einfache, billige Herstellung und Anwendung geeignet.However, the above methods have disadvantages. First, they are designed for large-scale industrial application and therefore have the disadvantage that they are very large, technically very complex and therefore expensive. On the other hand, they are not suitable for simple, cheap manufacture and application.
In der Offenlegungsschrift
Der Erfindung liegen folgende Probleme zugrunde:
- 1. Die Trennung der verschiedenen Materialien (PET, PP, HDPE), die in verschiedenen Arbeitsgängen nach der Zerkleinerung der Flaschen stattfindet, ist sehr aufwändig und fehlerbehaftet.
- 2. Eine Trennung der Materialien zu einem frühestmöglichen Zeitpunkt des Recycle-Prozesses ist möglich, wenn die Verschlüsse und die Etiketten vor dem Schreddern der PET-Flaschen entfernt werden.
- 3. Während die Verschlusskappen leicht von Hand entfernt werden können, sind die Etiketten äußerst fest mit dem Flaschenkörper verbunden. Sie können nur entfernt werden, wenn sie aufgerissen oder aufgeschnitten werden.
- 4. Ein Aufschneiden der Etiketten von Hand, mit einem scharfen Messer oder ähnlichem Werkzeug, ist extrem schwierig und extrem verletzungsanfällig, weshalb dieses Verfahren relativ selten angewendet wird.
- 5. Mit einfachsten technischen Mitteln soll ein brauchbares Gerät geschaffen werden, das die Technik radikal reduziert und als Laser ist ein billiger handelsüblicher Laser mit einer geringen Leistung von 5 Watt eingesetzt.
- 1. The separation of the different materials (PET, PP, HDPE), which takes place in different operations after the crushing of the bottles, is very complex and error-prone.
- 2. Separation of the materials at the earliest possible stage of the recycle process is possible if the closures and labels are removed prior to shredding the PET bottles.
- 3. While the caps can easily be removed by hand, the labels are extremely tightly connected to the body of the bottle. They can only be removed if they are ripped open or cut open.
- 4. Cutting the labels by hand with a sharp knife or similar tool is extremely difficult and extremely prone to injury, which is why this method is relatively rarely used.
- 5. With the simplest technical means to create a useful device that reduces the technology radically and as a laser is a cheap commercial laser used with a low power of 5 watts.
Diese Aufgabe, die Trennung der verschiedenen Materialien einer PET-Getränkeflaschen vor der Zerkleinerung mit dem Schredder, wird erfindungsgemäß durch die kennzeichnenden Merkmale der Schutzansprüche 1–3 gelöst.This object, the separation of the different materials of a PET beverage bottles before shredding with the shredder, is achieved by the characterizing features of the claims 1-3.

Vorteile der Erfindung:Advantages of the invention:
Der wesentliche Vorteil der Erfindung ist, dass die erfindungsgemäße Vorrichtung zum Aufschneiden und Entfernen von Etiketten an PET-Flaschen, in kleinmaßstäblichen Verhältnissen gefertigt und eingesetzt werden kann. Die Vorrichtung lässt sich an dezentralen Sammelstellen kostengünstig aufstellen und die Trennung der verschiedenen Materialien erfolgt zu einem sehr frühen Zeitpunkt des Recycele-Prozess.The essential advantage of the invention is that the device according to the invention for cutting and removing labels on PET bottles can be manufactured and used in small-scale ratios. The device can be set up at decentralized collection points inexpensively and the separation of the different materials takes place at a very early stage of the recycle process.
Durch einen nachgeschalteten Schredder kann das sortenreine Material geschreddert und in sog. Big-Bags abgefüllt werden. Das reduziert die Transportkosten und bringt bessere Erlöse beim Verkauf des recycelten Materiales, da dieses bereits sortenrein getrennt ist.By a downstream shredder, the unmixed material can be shredded and filled into so-called big bags. This reduces the transport costs and brings better proceeds when selling the recycled material, since this is already separated by type.
