Description
Förderrolle für heiße Glasplatten Die Erfindung bezieht sich auf aus einer inneren Tragwelle und einem darübergeschobenen, frei ausdehnbar gelagerten, rohrförmigen Arbeitsmantel bestehende Förderrollen für heiße Glasplatten, die insbesondere zur Verwendung in Rollenkühlöfen bestimmt sind. Diese Förderrollen sind infolge des Einflusses der hohen Temperaturen der Glasplatten und der im Kühlofen herrschenden Temperaturen starken Dehnungsbeanspruchungen unterworfen, die sich in Durchbiegungen der Rollen auswirken, welche der Ebenheit der Glasplatten nachträglich sind und die Lebensdauer der Rollen verkürzen.Conveyor roller for hot glass plates The invention relates to from an inner support shaft and a freely expandable, slid over it, tubular working jacket existing conveyor rollers for hot glass plates, in particular are intended for use in roller cooling furnaces. These conveyor rollers are a result the influence of the high temperatures of the glass plates and those in the cooling furnace Temperatures are subject to great strain, which results in deflections of the roles, which are detrimental to the flatness of the glass plates and shorten the life of the rollers.
Die Erfindung hat den Zweck, die Förderrollen so auszubilden, daß die schädlichen Durchbiegungen auf ein Mindestmaß herabgesetzt werden. Dieser Zweck wird dadurch erreicht, daß der Arbeitsmantel nur an wenigen, auf seiner Länge verteilten Stützpunkten mit der Tragwelle in Berührung steht, so daß eine möglichst geringe Wärmeübertragung auf die Tragwelle stattfindet. Einerseits wird durch die bekannte freie Dehnbarkeit des Mantels die Entstehung der die Durchbiegung hervorrufenden Spannungen verhindert, und anderseits bleibt die innere Tragwelle, da die Temperaturen wenig Einfluß auf sie haben, gerade und wirkt deshalb Durchbiegungen entgegen. Um die Tragwelle noch mehr gegen die Temperatureinflüsse zu schützen, werden gemäß der Erfindung zwischen ihr und dem Mantel Wärmeisolierungen vorgesehen. Außerdem kann die Welle in an sich bekannter Weise durch Hindurchleiten eines Kühlmittels gekühlt werden. Die Zweiteiligkeit der Walze hat den Vorteil, daß der Mantel nach Verschleiß oder Beschädigung leicht abgenommen und ausgebessert oder ersetzt werden kann.The invention has the purpose of designing the conveyor rollers so that the harmful deflections are reduced to a minimum. This purpose is achieved by the fact that the work coat is distributed over its length only to a few Support points is in contact with the support shaft, so that the lowest possible Heat transfer takes place on the support shaft. On the one hand it is known by the free extensibility of the jacket is what causes the deflection Tensions prevented, and on the other hand, the inner support shaft, because the temperatures have little influence on them, straight and therefore counteracts deflection. Around to protect the support shaft even more against the effects of temperature, are according to of the invention provided between it and the jacket thermal insulation. aside from that can the shaft in a known manner by passing a coolant be cooled. The two-part design of the roller has the advantage that the jacket is after Wear or damage can easily be removed and repaired or replaced can.
In der Zeichnung ist eine beispielsweise Ausführungsform einer Förderrolle gemäß der Erfindung im Längsschnitt dargestellt.In the drawing is an example embodiment of a conveyor roller shown according to the invention in longitudinal section.
a ist der rohrförmige Arbeitsmantel und h ist die innere Tragwelle. Zwischen den beiden sind Wärmeisolierungen c vorgesehen. Der Mantel a ist bei d lösbar nur auf einem Ende der Tragwelle befestigt, so daß er sich in der Längsrichtung frei ausdehnen und zusammenziehen kann. Der Mantel steht mit der Welle nur an wenigen Stützpunkten in Berührung, die auf der Länge des Mantels verteilt, in der gezeigten Ausführung von dessen Enden und zwei schmalen mittleren Ringrippen e gebildet werden. Die Tragwelle ist hohl, um ein Kühlmittel durchleiten zu können.a is the tubular working jacket and h is the inner support shaft. Thermal insulation c is provided between the two. The jacket a is releasably attached to only one end of the support shaft at d so that it can freely expand and contract in the longitudinal direction. The jacket is only in contact with the shaft at a few support points which are distributed along the length of the jacket and, in the embodiment shown, are formed by its ends and two narrow central annular ribs e. The support shaft is hollow so that a coolant can be passed through.
