Description

Die Erfindung betrifft eine Vorrichtung zum Trennen von Kunststoffprodukten mit unterschiedlichen Erweichungs­ punkten gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for separating Plastic products with different softening score according to the preamble of claim 1.

Die Trennung von zerkleinerten Kunststoffabfällen mit höheren und niedrigen spezifischen Gewichten als eine Waschflüssigkeit ist in der DE-PS 28 04 729 beschrieben. Hier erfolgt die Trenn­ ung in einem Schwimm-Sink-Verfahren.The separation of shredded plastic waste with higher and low specific weights as a washing liquid is described in DE-PS 28 04 729. The separation takes place here in a swim-sink process.

Demgegenüber fallen verschmutzte, unterschiedliche Kunststoff­ produkte an, deren spezifische Gewichte so eng beieinander lie­ gen, daß eine Schwimm-Sink-Trennung nach der Zerkleinerung nicht möglich ist. So fallen verschmutzte Kunststoff-Formteile, wie Flaschen, Kästen od. dgl. an, die aus Polyester (PET) und Poly­ vinylchlorid (PVC) bestehen. Beide Materialien haben nahezu gleiche spez. Gewichte.In contrast, dirty, different plastics fall products whose specific weights were so close together gene that a swim-sink separation after crushing is not is possible. So dirty plastic moldings fall, like Bottles, boxes or the like. Made of polyester (PET) and poly vinyl chloride (PVC) exist. Both materials have almost same spec. Weights.

Zur Trennung derartiger Materialien (wobei auch andere Kombi­ nationen denkbar sind) wurden diese vor dem Recycling auf För­ derbänder aufgegeben und dort manuell getrennt. Aufgrund mensch­ licher Fehler ist auch hier eine 100%ige Trennung nicht mög­ lich. Um die Fehlerquellen zu verringern, wurde ein Röntgen­ strahlen-Verfahren eingesetzt. Die Strahlen können Chloride enthaltende Teile erfassen und somit PVC von PET trennen. Ab­ gesehen von den hohen Kosten und der Strahlengefährdung für das Personal ist auch hier eine 100%ige Trennung nicht möglich. Sind z. B. die Formteile mit Aufkleber versehen, dann können die Strahlen das Kunststoffmaterial nicht erfassen, so daß es wie Materialien ohne Chloridanteile behandelt wird.For the separation of such materials (although other combinations  nations are conceivable) these were recycled to För derband abandoned and separated there manually. Because of human 100% separation is not possible here either Lich. To reduce the sources of error, an X-ray was taken radiation process used. The rays can be chlorides Detect contained parts and thus separate PVC from PET. From seen from the high cost and exposure to radiation for here, too, the staff cannot be separated 100%. Are z. B. provide the moldings with stickers, then you can the rays do not capture the plastic material, so that it how materials without chloride are treated.

Aus der DE 37 22 777 A1 ist eine Einrichtung zum Aussortieren thermoplastischer Kunststoffteile aus einem Gemengestrom mit einem beheizten, umlaufenden Stahlband bekannt. Teile der Kunst­ stoffpartikel kleben an dem Stahlband fest. Die nicht festgekleb­ ten Teilchen werden ausgesondert. Bei dieser bekannten Einrichtung werden die zu trennenden Kunststoffteile durch eine Kaskadenan­ ordnung stufenförmig transportiert. Die Kaskade verursacht nicht nur einen hohen Investitionsaufwand, auch kann mit ihr nicht verhindert werden, daß Teile des zu trennenden Kunststoffes immer auf der Oberfläche des Gemengestromes verbleiben und folglich diese Teile nicht an die Oberfläche des Stahlbandes gelangen. Eine sichere Trennung ist somit nicht gegeben.DE 37 22 777 A1 describes a device for sorting out thermoplastic parts from a batch flow with a heated, rotating steel belt known. Parts of art Fabric particles stick to the steel belt. The not stuck Particles are separated out. With this known device the plastic parts to be separated are cascaded order transported in stages. The cascade doesn't cause only a high investment, also can not with it be prevented that parts of the plastic to be separated always remain on the surface of the batch flow and consequently this Parts do not reach the surface of the steel belt. A there is no safe separation.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mit der unterschiedliche Kunststoffprodukte absolut sicher voneinander getrennt werden können.The invention has for its object a device create with which different plastic products absolutely can be safely separated from each other.

Diese Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst. This object is achieved with the features of patent claim 1.  

Ist die Temperatur des Stahlbandes so eingestellt, daß die Kunststoffteilchen mit dem niedrigen Erweichungspunkt an der Oberfläche des Stahlbandes anhaften, so können sich die Kunst­ stoffteilchen mit dem höheren Erweichungspunkt frei darüber bewegen und an einem Ende des Stahlbandes abgeführt werden. Die am Stahlband anhaftenden Kunststoffteilchen werden von diesem am anderen Ende des Stahlbandes abgenommen. Dies be­ deutet, daß z. B. PVC-Teilchen anhaften und sich somit die PET- Teilchen frei bewegen können. Dabei wird die Temperatur der Unterlage so eingestellt, daß der an sich bekannte Plastifi­ zierpunkt gerade erreicht wird und demzufolge dieses Material, nach der Abtrennung der anderen Komponente, ohne Schwierigkeiten von der Unterlage abgeschabt werden kann.Is the temperature of the steel strip set so that the Plastic particles with the low softening point on the Stick to the surface of the steel strip, so the art can particles with the higher softening point freely above move and be removed at one end of the steel belt. The plastic particles adhering to the steel strip are from removed from the other end of the steel strip. This be indicates that e.g. B. PVC particles stick and thus the PET Particles can move freely. The temperature of the Document set so that the well-known plastifi decorative point is just reached and therefore this material, after separating the other component, without difficulty can be scraped off the surface.

Mittels der Vibratoren werden die freifließenden Kunststoffteil­ chen ständig aufgerüttelt und damit laufend umgeschichtet. Mit dieser Maßnahme wird erreicht, daß nahezu alle Teilchen mit dem niedrigen Erweichungspunkt an die beheizte Oberfläche des Stahl­ bandes gelangen und dort anhaften.Using the vibrators, the free-flowing plastic parts chen constantly shaken and thus continuously shifted. With This measure ensures that almost all particles with the low softening point to the heated surface of the steel bandes arrive and adhere there.

Eine vorteilhafte Beheizung des Stahlbandes kann aus einem mit Breitdüsen versehenen Heißluftkasten bestehen, der unterhalb des Ober­ trums des Stahlbandes angeordnet und mit einer Heißluftleitung verbunden ist. An advantageous heating of the steel strip can be done with a Wide-nozzle hot air box exist, the one below the top strums of the steel strip arranged and connected to a hot air line is.  

Die Erfindung ist nicht an das beschriebene Beispiel, Trennung von PET- und PVC-Teilchen, gebunden. So lassen sich auch andere Materialien, wie Polystyrol (PS) oder die Kombination PVC/PS von PET trennen. Auch können Heißkleber (HOT-MELT) von PET ge­ trennt werden.The invention is not related to the example described, separation of PET and PVC particles. This is how others can be Materials such as polystyrene (PS) or the combination PVC / PS separate from PET. Hot glue (HOT-MELT) from PET can also be used be separated.

Die Erfindung wird durch eine in der Zeichnung dargestellte Ausführungsform nachfolgend erläutert.The invention is illustrated by one in the drawing illustrated embodiment explained below.

Als Trennvorrichtung 33 ist ein über Umlenkrollen 35, 36 umlaufen­ des Stahlband 34 vorgesehen.A steel belt 34 is provided as a separating device 33 which runs around deflection rollers 35 , 36 .

Die Umlenkrollen 35, 36 sind in Wellen 37, 38 mit Lagern 39, 40 abgestützt. Mittels eines Motors 41 wird das Stahlband 34 mit einer Laufrichtung gemäß Pfeil 42 angetrieben. Unterhalb des Obertrums des Stahlbandes 34 ist ein Heißluftkasten 43 vorgesehen, der an eine Heißluftleitung 44 angeschlossen ist. Im oberen Teil des Heißluftkastens 43 sind Breit- Luftdüsen 45 zum Beheizen des Stahlbandes 4 angeordnet. Im Bereich zwischen den beiden Umlenkrollen 35, 36 befindet sich oberhalb des Stahlbandes 34 ein Aufgabevorrichtung 46 mit vorgeschaltetem Silo 46a , mittels der die zerkleinerten, gereinigten und getrockneten unterschiedlichen Kunststoffprodukte auf das Stahlband 34 in dünner Schicht aufgegeben werden. Unterhalb der Achse "B" befinden sich einerseits die Auffangvorrichtung 47 für die PET-Teilchen 48 und andererseits die Abnahmevorrichtung 49 mit dem Schaber 50 für die PVC-Teilchen 58. Die gesamte Vorrichtung 33 ist mittels Stützen 53, 54 auf zwei Unwucht-Vibratoren 51, 52 abgestützt. Diese sind so eingestellt, daß die frei fliegenden PET-Teilchen 48 eine Transport­ richtung gemäß Pfeil 53 erhalten. Vibration und Lage der Einrichtung 33 können derart eingestellt werden, daß sich die PET-Teilchen mittels vorbestimmter Wurfparabeln über das Stahlband bewegen. Somit wird erreicht, daß alle PVC-Teilchen 58 Kontakt mit dem heißen Stahlband 34 bekommen und dort anhaften. Folglich kann die Trenn­ vorrichtung 33 so gefahren werden, daß aus der Leitung 55 nur PET- Teilchen entnommen werden. Die 100%ige Trennung von PET- und PVC-Teilchen (oder anderen Komponenten) wird somit infolge der verschiedenen Bewegungsrichtungen beider Materialien auf dem Stahlband 34 erreicht.The deflection rollers 35 , 36 are supported in shafts 37 , 38 with bearings 39 , 40 . The steel belt 34 is driven by a motor 41 with a running direction according to arrow 42 . A hot air box 43 , which is connected to a hot air line 44 , is provided below the upper run of the steel strip 34 . Wide air nozzles 45 for heating the steel strip 4 are arranged in the upper part of the hot air box 43 . In the area between the two deflection rollers 35 , 36 , above the steel belt 34, there is a feed device 46 with an upstream silo 46 a, by means of which the shredded, cleaned and dried different plastic products are fed onto the steel belt 34 in a thin layer. Below the axis "B" are on the one hand the collecting device 47 for the PET particles 48 and on the other hand the removal device 49 with the scraper 50 for the PVC particles 58 . The entire device 33 is supported on two unbalance vibrators 51 , 52 by means of supports 53 , 54 . These are set so that the free-flying PET particles 48 receive a transport direction according to arrow 53 . Vibration and position of the device 33 can be adjusted in such a way that the PET particles move over the steel strip by means of predetermined throwing parabolas. This ensures that all PVC particles 58 come into contact with the hot steel strip 34 and adhere there. Consequently, the separation device 33 can be operated so that only PET particles are removed from the line 55 . The 100% separation of PET and PVC particles (or other components) is thus achieved due to the different directions of movement of both materials on the steel belt 34 .
