Abstract

A glass sorting apparatus for the removal of non-glass components from a mixture includes a slide on which the parts are moved in a discrete fashion such that they can be individually identified when moving over a slide window through which light is passed and the slide has a gate arranged downstream of the window which gate is momentarily opened when a non-glass part is identified by the light such that the non-glass part is discharged through the gate so as to be separated from the mixture.

Description

Die Erfindung betrifft eine Aussonderungseinrichtung einer Glas-Sortieranlage, die zum Aussondern von Nicht-Glas oder von mit Nicht-Glas-Resten behafteten Glasteilen dient.The invention relates to a sorting device of a glass sorting system, which is used for separating non-glass or glass parts contaminated with non-glass residues.

Im Zuge des steigenden Umweltbewußtseins, wie auch der Energieeinsparung, ist man allgemein bestrebt, gebrauchte Materialien wieder aufzuarbeiten. Dies ist auch bei Glas der Fall, das einen wertvollen Abfallstoff darstellt, in den zu seiner Herstellung schon verhältnismäßig viel Ener­gie aufgewandt wurde. Glas und Glasabfälle werden daher bereits in größerem Maße gesammelt, um es einer Wiederver­wertung zuführen zu können.In the course of increasing environmental awareness, as well as energy saving, efforts are generally being made to recycle used materials. This is also the case with glass, which is a valuable waste material in which a relatively large amount of energy has already been used to manufacture it. Glass and glass waste are therefore already being collected to a large extent so that they can be recycled.

Dieses Altglas trifft in Form von Scherben und Flaschen in stark verunreinigtem und mit anderen Materialien durchsetz­ten Zustand beim Glasverwerter ein. Es muß daher, vor seiner Verwertung, von den Verunreinigungen befreit und im allemeinen auch nach den verschiedenen Glassorten und Glas­farben sortiert werden. Die Erfindung betrifft eine Entfer­nung von Verunreinigungen aus dem Glas beziehungsweise das Aussondern von Nicht-Glas und mit Nicht-Glas-Resten behafte­ten Glasteilen aus dem Glasgemenge.This waste glass arrives at the glass recycling company in the form of broken glass and bottles in a highly contaminated and interspersed state. Before it is used, it must therefore be freed of impurities and, in general, sorted according to the different types of glass and glass colors. The invention relates to the removal of impurities from the glass or the separation of non-glass and glass parts with non-glass residues from the glass batch.

Außerordentlich störend wirken sich Keramik- und Tonanteile bei dem Altglasgemenge aus, die sich auch immer wieder in größerem Maße in solchen Glasabfällen befinden. Dies rührt daher, weil vom Verbraucher, der die Glasabfälle zu den Glas-Sammelstellen bringt, irrtümlicherweise Keramik und Tonwaren gleichgestellt werden mit Glas und Glaswaren. Ver­unreinigungen sind aber auch Metallanteile, sei es nun in Form von aufgeklebten Metallfolien, von Überresten von Schraubverschlüssen oder auch von Bügelverschlüssen. Ande­rerseits finden sich bei derartigen Glasabfällen für die Wiederverwertung nicht störende aufgeklebte Papieretiketten oder sonstige leicht brennbare organische Bestandteile.Ceramic and clay components in the waste glass batch have an extremely disruptive effect, and are repeatedly found to a large extent in such glass waste. This is because the consumer who brings the glass waste to the glass collection points mistakenly equates ceramics and pottery with glass and glassware. Impurities are also metal components, be it in the form of glued-on metal foils, remnants of screw closures or clip closures. On the other hand, in the case of glass waste of this type, there are paper labels or other easily flammable organic constituents which are not annoying for recycling.

Um diese störenden Materialien aus dem Glasgemenge zu ent­fernen, war bisher nur die Möglichkeit gegeben, das über ein Förderband herangeführte Gemenge manuell zu sortieren beziehungsweise die störenden Materialien auszusondern. Zwar wurden Versuche zum maschinellen Sortieren des Glas­gemenges durchgeführt, jedoch führten diese Versuche nicht zum Erfolg. Dies einerseits, weil es nicht gelang, die störenden Bestandteile gezielt aus dem Glasgemenge zu ent­fernen und andererseits, weil die eingesetzten Sensoren nur bedingt fähig waren, Nicht-Glas von Glasbestandteilen zu unterscheiden.In order to remove these interfering materials from the glass batch, it was previously only possible to manually sort the batch that was brought in via a conveyor belt or to separate the interfering materials. Attempts to machine the glass batch have been carried out, but these attempts have not been successful. This is on the one hand because it was not possible to remove the disruptive components from the glass batch and on the other hand because the sensors used were only able to distinguish non-glass from glass components to a limited extent.

Zum Erkennen von Glas beziehungsweise von Nicht-Glas bietet sich das Durchleuchten der Materialien an, da sämtliche störenden Materialien undurchsichtig sind. Zu bedenken ist allerdings, daß auch mit Papier beklebtes Glas nicht mehr durchsichtig ist, also auch ausgeschieden wird, obwohl es, wie oben angeführt, die Glasverwertung nicht stört. Gerade aber mit Papieretiketten etc. beklebte Gläser bilden einen Großteil des Glasgemenges, so daß beim Versuch dieser maschinellen Aussonderung viel zu viel Glas zusammen mit den tatsächlichen Verunreinigungen ausgeschieden wurde.In order to recognize glass or non-glass, it is advisable to examine the materials, since all the disruptive materials are opaque. It should be borne in mind, however, that glass stuck to paper is no longer transparent, so it is also eliminated, although, as mentioned above, it does not interfere with glass recycling. Glasses stuck with paper labels etc. form a large part of the glass batch, so that when attempting this mechanical separation, far too much glass was removed together with the actual impurities.

Aufgabe der Erfindung ist es daher, eine Einrichtung anzu­geben, die es ermöglicht, die störenden Materialien auszu­sondern, ohne allzu viele brauchbare Glasbestandteile dem Glasgemenge zu entnehmen. Erreicht wird dies nach der Erfin­dung durch eine zwischen eine das Glasgemenge zuführende Zuführeinrichtung und eine wegführende Abführeinrichtung eingefügte Rutsche, an deren Ende eine nach unten weg­schwenkbare Klappe angeordnet ist, sowie eine die Rutsche zwischen sich aufnehmende, quer zur Transportrichtung des Glasgemenges angeordnete, die Klappenbewegung steuernde, Licht-Sende- und -Empfangsvorrichtung.The object of the invention is therefore to provide a device which makes it possible to separate out the disruptive materials without removing too many usable glass components from the glass batch. This is achieved according to the invention by a slide inserted between a feed device feeding the batch of glass and a discharge device leading away, at the end of which a flap which can be pivoted downward is arranged, and a slide which accommodates the slide between itself and which is arranged transversely to the transport direction of the batch and controls the flap movement , Light transmitting and receiving device.

Bei der Einrichtung nach der Erfindung wird das zu sortie­rende Glasgemenge über eine Rutsche geleitet, wobei die einzelnenn Bestandteile dieses Gemenges vereinzelt werden. Hiedurch ist es möglich, die Bestandteile dieses Gemenges mittels der Licht-Sende- und -Empfangsvorrichtung zu iden­tifizieren, also zu klassifizieren nach Glas- und sonstigen Bestandteilen. Befindet sich hierbei Nicht-Glas im Gemenge, wird über die Licht-Sende- und -Empfangsvorrichtung die Klappe so gesteuert, daß nach einer der Materialgeschwin­digkeit auf der Rutsche entsprechenden Zeitspanne die Klappe geöffnet wird, dieser Nicht-Glas-Bestandteil also aus dem Glasgemenge entfernt wird. Selbstverständlich werden beim Öffnen der Klappe auch Glasbestandteile aus dem Glasgemenge entfernt, jedoch nur in einem in der Praxis bedeutungslosen Maße. Sollten sich bei diesem ausgeschiede­nen Gemenge noch beachtliche Glasbestandteile befinden, so kann die Aussonderung ohne Schwierigkeiten nochmals wieder­holt werden.In the device according to the invention, the batch of glass to be sorted is passed over a slide, the individual components of this batch being separated. In this way it is possible to identify the components of this batch by means of the light transmitting and receiving device, that is, to classify them according to glass and other components. If there is non-glass in the batch, the flap is controlled via the light-transmitting and receiving device in such a way that the flap is opened after a period of time corresponding to the material speed on the slide, so this non-glass component is removed from the batch of glass becomes. Of course, when the flap is opened, glass components from the Batch of glass removed, but only to an insignificant extent in practice. If there are still significant glass components in this separated batch, the rejection can be repeated again without difficulty.

Das Erkennen von Nicht-Glas durch die Licht-Sende- und -Empfangsvorrichtung kann durch die Wahl der Licht-Wellen­länge beeinflußt werden. Nach der Erfindung ist hierzu nicht nur der sichtbare Anteil des Lichts, sondern auch der Ultraviolett-Anteil wie auch der Infrarot-Anteil zu verwer­ten. So kann es für manche Sortieraufgaben zweckmäßig sein, den Ultraviolett-Anteil zwischen 300 nm und 380 nm, der im wesentlichen also dem Bereich UV-A entspricht, eingesetzt werden, insbesondere um Spezialgläser voneinander zu trennen. Gerade aber für das übliche Altglas empfiehlt sich eine Wellenlänge, die im nahen Infrarot liegt, da diese Wellenlänge wohl aufgeklebte Papieretiketten, nicht aber Metallanteile durchdringt. Dadurch passieren mit Papier beklebte Glasanteile die Aussonderungseinrichtung nach der Erfindung, nicht aber mit Metall behaftete Glasanteile. Besonders gute Ergebnisse lassen sich unter Verwendung von Laserlicht erzielen, insbesondere dann, wenn die Licht­empfangsvorrichtung aus einer Mehrzahl von nebeneinander angeordneten Lichtwandlern gebildet ist und das Laserlicht durch Glasfasern über diese Lichtwandler geführt wird. Als Lichtwandler kommen sowohl Fotozellen, Fotoelemente, Foto­dioden wie auch Fotowiderstände in Frage, jeweils für den angewendeten Frequenzbereich.The detection of non-glass by the light transmitting and receiving device can be influenced by the choice of the light wavelength. According to the invention, not only the visible part of the light but also the ultraviolet part as well as the infrared part is to be used for this purpose. For some sorting tasks it can be useful to use the ultraviolet component between 300 nm and 380 nm, which essentially corresponds to the UV-A range, especially to separate special glasses. However, a wavelength that is in the near infrared is particularly recommended for conventional waste glass, since this wavelength penetrates paper labels that are stuck on, but does not penetrate metal parts. As a result, glass portions glued to paper pass through the separating device according to the invention, but not glass portions containing metal. Particularly good results can be achieved using laser light, in particular when the light receiving device is formed from a plurality of light converters arranged next to one another and the laser light is guided through glass fibers via these light converters. Both photo cells, photo elements, photo diodes and photo resistors can be used as light converters, each for the frequency range used.

Um eine gegenseitige Beeinflussung der Lichtwandler zu ver­meiden, werden sie zweckmäßigerweise im Grund von licht­abschattenden Röhren angeordnet.In order to avoid mutual interference between the light converters, they are expediently arranged in the base of light-shading tubes.

Tatsächlich haben mit einer derartigen Einrichtung durchge­führte Versuche gezeigt, daß es mit ihr möglich ist, sehr exakt und mit lediglich geringen Glasanteilen Nicht-Glas aus einem Glasgemenge zu trennen, so daß das so sortierte Glas unschwer einer Wiederverwertung zugeführt werden kann.In fact, tests carried out with such a device have shown that it is possible with it to separate non-glass from a glass batch very precisely and with only small glass fractions, so that the glass sorted in this way can be easily recycled.

Auf der Zeichnung ist schematisch eine derartige Aussonde­rungseinrichtung dargestellt, und zwar zeigen:

  • Fig. 1 eine Anordnungsskizze und
  • Fig. 2 die Draufsicht auf eine Lichtempfangs­vorrichtung.
Such a sorting device is shown schematically in the drawing, namely:
  • Fig. 1 is a layout sketch and
  • Fig. 2 is a plan view of a light receiving device.

Über eine Zuführvorrichtung 1 wird Glasgemenge einer Rutsche 2 zugeleitet, auf der es über eine Klappe 3 zu einer wegführenden Abführeinrichtung 4 rutscht. Umfangen wird die Rutsche 2 von einer Licht-Sende- und -Empfangsvor­richtung 5, 6. Um einer Verfälschung der Aussage vorzubeu­gen, kann es zweckmäßig sein, die Licht-Sendevorrichtung unterhalb der Rutsche 2 und die Licht-Empfangsvorrichtung oberhalb von ihr anzuordnen. Die Rutsche 2 weist einen durchsichtigen Teil 7 auf, der von Licht der Licht-Sende- und -Empfangsvorrichtung 5, 6 durchstrahlt wird. Der Licht-­mEpfangsteil besteht, wie Fig. 2 zeigt, aus einer Mehrzahl von Lichtwandlern 8, die so neben und hintereinander ange­ordnet sind, daß mit Sicherheit die unter- beziehungsweise oberhalb vorbeirutschenden Bestandteile des Glasgemenges erfaßt werden.Mixture of glass is fed to a chute 2, on which it slides via a flap 3 to a discharge device 4 leading away. The chute 2 is encompassed by a light transmitting and receiving device 5, 6. In order to prevent the statement from being falsified, it may be expedient to arrange the light transmitting device below the chute 2 and the light receiving device above it. The slide 2 has a transparent part 7, which is irradiated by light from the light transmitting and receiving device 5, 6. The light-m Ep trapping part, as shown in FIG. 2, consists of a plurality of light converters 8, which are arranged next to and one behind the other so that the components of the batch of glass sliding below or above are detected with certainty.

Das über die Zuführeinrichtung 1 herangeführte Glasgemenge rutscht auf der Rutsche 2 vereinzelt in Richtung auf die Abführeinrichtung 4 und passiert hierbei die Licht-Sende- und Empfangsvorrichtung 5, 6. Befindet sich Nicht-Glas unter dem zugeführten Glasgemenge, so wird mit einer der Rutschgeschwindigkeit des Glasgemenges entsprechenden Ver­zögerungszeit schlagartig die Klappe 3, beispielsweise durch einen Elektromagneten, geöffnet, so daß dieser Nicht-Glas-Bestandteil in einen Abfallbehälter 9 fallen oder einer nochmaligen Sortierung zugeleitet werden kann. Glasanteile hingegen rutschen auf der Rutsche 2 über die Klappe 3 hinweg und gelangen in die wegführende Abführein­richtung 4 zur weiteren Verwendung.The batch of glass brought up via the feed device 1 occasionally slides on the slide 2 in the direction of the discharge device 4 and passes the light-transmitting and receiving device 5, 6. If there is non-glass under the batch of glass being fed in, one of the slipping speeds becomes Glass batch corresponding delay time suddenly opened the flap 3, for example by an electromagnet, so that this Non-glass component can fall into a waste container 9 or be re-sorted. Glass parts, on the other hand, slide on the slide 2 over the flap 3 and reach the discharge device 4 leading away for further use.
