Abstract
Description
Die Erfindung ist auf ein Verfahren und eine Anlage zur Aufbereitung von Bildröhren, insbesondere von Farbbildröhren, gerichtet, wobei die aus ver schiedenen Glasteilen, dem Konus und dem Schirm, die mit einem Glaslot mit einander verklebt sind, sowie aus verschiedenen metallischen Bestandteilen zu sammengesetzten Bildröhren in ihre einzelnen Bestandteile voneinander ge trennt werden.The invention relates to a method and a plant for the preparation of Picture tubes, especially of color picture tubes, directed, the ver various glass parts, the cone and the shade, which are covered with a glass solder are glued to each other, as well as from different metallic components composed picture tubes in their individual components from each other be separated.
Bildröhren, die überwiegend aus Glas bestehen, und zwar aus unterschiedlichen Glassorten, beispielsweise aus dem Bleioxid enthaltenden Konusglas und dem Bariumoxid und Strontiumoxid enthaltenden Schirmglas, müssen, wenn sie einer Wiederverwertung zugeführt werden sollen, zu sortenreinen Glasproduk ten voneinander getrennt werden, wobei auch die restlichen vorwiegend metal lischen Bestandteile abzutrennen sind.Picture tubes, which consist predominantly of glass, from different Glass types, for example from the cone glass containing lead oxide and the Screen glass containing barium oxide and strontium oxide, if necessary are to be recycled into single-product glass products ten are separated from each other, with the rest predominantly metal components are to be separated.
Bei einem aus der DE-OS 41 30 531 bekannten Verfahren, das die Rückgewin nung der metallischen Wertstoffe zum Ziel hat, werden die Bildröhren zunächst zerkleinert und dann durch verschiedene trockene Aufbereitungsstufen, wie bei spielsweise Siebung, Attrition, Magnetscheidung, Sichtung, in metallische Wertstoffe und ein das Glas enthaltendes Mischprodukt getrennt. Eine weiter gehende Trennung des Glasmischprodukts wird nicht durchgeführt.In a method known from DE-OS 41 30 531, the recovery The aim of the first step is to create the metallic recyclables crushed and then through various dry preparation stages, as with for example screening, attrition, magnetic separation, sighting, in metallic Recyclables and a mixed product containing the glass separately. Another one ongoing separation of the glass mixed product is not carried out.
Das bekannte Verfahren nach der DE-OS 39 01 842 und der DE-OS 40 03 497 (Zusatz zur DE-OS 39 01 842) vermeidet die Entstehung eines Glasmischpro dukts dadurch, daß vor einer späteren Zerkleinerung zunächst mittels einer Trennscheibe (z. B. einer Diamantscheibe) das Schirmglas vom Konusglas ab getrennt und beide Glassorten getrennt weiterbehandelt werden. Das Ergebnis dieses Verfahrens sind dann sortenreine Glasprodukte. Nachteilig ist aber bei diesem Verfahren, daß jede Bildröhre einzeln manuell aufgeschnitten (gesägt) werden muß und - bei Verwendung einer Diamantscheibe - das zum Trennen mit Diamantscheiben benötigte Wasser in die Glasprodukte eingebracht wird, so daß zunächst eine weitere trockene Behandlung (Aufbereitung) erschwert wird.The known method according to DE-OS 39 01 842 and DE-OS 40 03 497 (Addition to DE-OS 39 01 842) avoids the formation of a glass mixing pro ducts in that, before a later comminution, first by means of a Cutting disc (e.g. a diamond disc) the screen glass from the cone glass separately and both types of glass are processed separately. The result this process is then pure glass products. A disadvantage is this process that each picture tube individually cut open (sawn) must be and - when using a diamond wheel - that to separate water required with diamond disks is introduced into the glass products, so that further dry treatment (reprocessing) is difficult at first becomes.
Es ist Aufgabe der Erfindung, ein Verfahren und eine Vorrichtung zu schaffen, mit dem bzw. mit der eine sortenreine Trennung der Glasanteile von Bildröhren ohne aufwendiges manuelles Arbeiten möglich ist.It is an object of the invention to provide a method and a device with or with which a separate separation of the glass parts from picture tubes is possible without time-consuming manual work.
Diese Aufgabe wird verfahrensmäßig gelöst mit den Maßnahmen des Kenn zeichnungsteils des Anspruchs 1 und anlagenmäßig mit den Merkmalen des Kennzeichnungsteils des Anspruchs 4.This task is solved procedurally with the measures of the Kenn Drawing part of claim 1 and plant with the features of Labeling part of claim 4.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen ange geben.Advantageous embodiments of the invention are set out in the dependent claims give.
Bei dem erfindungsgemäßen Verfahren werden die Bildröhren ungetrennt in einer entsprechenden Vorrichtung, beispielsweise einem Durchlaufofen, auf eine Temperatur aufgeheizt, die unterhalb der Erweichungspunkte der Glasteile liegt, so daß diese noch formstabil bleiben. Die Temperatur ist aber so hoch ge wählt, daß sie oberhalb des Erweichungspunktes des Glaslotes liegt, mit dem die Glasteile miteinander verklebt sind, so daß die Klebkraft des Glaslotes redu ziert und das Schirmglas vom Konusglas abgetrennt werden kann. Die hierzu erforderliche äußere Krafteinwirkung kann senkrecht zur Klebenaht durch eine Zugkraft oder parallel zur Klebenaht durch eine Scherkraft aufgebracht werden und kann erfindungsgemäß in besonders vorteilhafter Weise durch das Eigenge wicht des abzutrennenden Glasteils aufgebracht werden. In the method according to the invention, the picture tubes are separated into a corresponding device, for example a continuous furnace a temperature is heated below the softening points of the glass parts lies, so that they remain dimensionally stable. But the temperature is so high chooses that it lies above the softening point of the glass solder with which the glass parts are glued together so that the adhesive strength of the glass solder redu adorned and the screen glass can be separated from the cone glass. The for this required external force can be applied perpendicular to the adhesive seam by a Tensile force or parallel to the adhesive seam by a shear force and can according to the invention in a particularly advantageous manner by Eigenge importance of the glass part to be separated.
Bei der Aufheizung in einem Durchlaufofen können gemäß der Erfindung bei spielsweise die Bildröhren an einer Transportvorrichtung aufgehängt und lang sam durch den Ofen transportiert werden, wobei die Transportgeschwindigkeit so geregelt eingestellt ist, daß die Bildröhren entsprechend einer vorgegebenen Kurve aufgeheizt und später abgekühlt werden, wodurch ein unerwünschtes Zerplatzen der Glasteile durch thermische Spannungen verhindert wird. Inner halb des Ofens fällt dann das untere Glasteil infolge seines Eigengewichts vom aufgehängten übrigen Rest ab. Beide Glasteile werden dann durch die Trans portvorrichtung aus dem Ofen ausgetragen. Vorteilhaft ist hierbei insbesondere, daß damit auch die Möglichkeit besteht, in einfacher Weise die getrennten Glasteile weiterhin getrennt zu behandeln und somit den Durchlaufofen als Sortiergerät zu nutzen.When heating in a continuous furnace can according to the invention for example, the picture tubes hung on a transport device and long sam are transported through the furnace, the transport speed is set so that the picture tubes correspond to a predetermined one Curve can be heated and later cooled, creating an undesirable Bursting of the glass parts is prevented by thermal stresses. Inner half of the furnace then the lower glass part falls off due to its own weight suspended remaining rest. Both parts of the glass are then trans port device discharged from the oven. It is particularly advantageous here that it is also possible to easily separate the Glass parts continue to be treated separately and thus the continuous furnace as To use sorting device.
Falls das Eigengewicht zu einem Lösen der Klebverbindung nicht ausreicht, ist es auch möglich, innerhalb des Ofens eine fest installierte Vorrichtung zur Einwirkung einer Kraft auf die Glasteile an der Stelle im Ofen anzuordnen, an der die Glasteile die vorgegebene Temperatur erreicht haben, oder es ist auch möglich, die Vorrichtung zum Lösen der Klebverbindung an der Transportein richtung so anzuordnen, daß sie mit den Bildröhren durch den Ofen geführt wird, wobei jeder Lösevorrichtung dann mindestens eine Bildröhre zugeordnet ist.If the dead weight is not sufficient to loosen the adhesive connection, it is also possible to have a permanently installed device for To place a force on the glass parts at the location in the furnace the glass parts have reached the specified temperature, or it is too possible, the device for releasing the adhesive connection on the Transporttein Arrange direction so that they are guided through the oven with the picture tubes is, each release device then assigned at least one picture tube is.
Anstelle des Durchlaufofens kann gemäß der Erfindung zur Aufheizung der Bildröhren auch beispielsweise ein Kammerofen verwendet werden, in dem die Bildröhren eingebracht und aufgeheizt werden und in dem dann das Lösen der Klebverbindungen durch eine entsprechende Vorrichtung erfolgt oder aber, das Lösen der Klebverbindung erfolgt nach dem Herausnehmen der aufgeheizten Bildröhren außerhalb des Ofens.Instead of the continuous furnace according to the invention for heating the Picture tubes can also be used, for example, a chamber furnace in which the Picture tubes are inserted and heated and then in the dissolving of the Adhesive connections are made by an appropriate device or else that The adhesive connection is released after removing the heated one Picture tubes outside the furnace.
