Abstract

Process for surface treatment of hollow articles made of glass in a glass working machine. The surface treatment is effected by means of glass moulds, the walls of which in contact with the hot glass are made of porous material, wherein the medium used for separating the glass from the mould is entirely or partially, in a continuous or intermittent manner, replaced by a medium which influences chemically and/or physically the surface of the glass in a desired manner.

Description

Vergüten von HohlglasgegenständenAnnealing of hollow glass objects

Die Erfindung betrifft ein Verfahren zur Vergütung von Hohlglasgegenständen in der Glasverarbeitungsmaschine.The invention relates to a method for tempering hollow glass objects in the glass processing machine.

Die Oberfläche von Hohlglas wird vergütet, um bei gleichem Gewicht eine höhere Festigkeit der Gegenstände zu erreichen oder bei gleicher Festigkeit mit niedrigerem Gewicht und geringerer Wandstärke arbeiten zu können.The surface of hollow glass is tempered in order to achieve a higher strength of the objects with the same weight or to be able to work with the same strength with a lower weight and lower wall thickness.

Es ist bekannt, daß die Vergütung der Oberfläche während des Laufs der Hohlgläser durch einen auf dasIt is known that the coating of the surface during the run of the hollow glasses by one on the

Transportband zum Kühlofen aufgesetzten Vergütungstunnel stattfindet, in dem die durchlaufenden Glasartikel mit einem Gas behandelt werden.Conveyor belt to the tempering tunnel set up in the cooling furnace takes place, in which the glass articles passing through are treated with a gas.

Dabei ist eine genaue Bemessung und Steuerung desThereby an exact dimensioning and control of the

Vergütungsvorganges nicht möglich. Weitere Nachteile sind eine verstärkte Umweltbelästigung durch das aus den Öffnungen des Tunnels ausströmende Gas und Produktionsausfälle durch umgefallene oder sich verklemmende Hohlglasartikel, die in oder vor dem Tunnel einen Stau heißer Gläser bewirken. Die heute benutzten Tunnel zur Vergütung von Hohlglasgegenständen verringern die Übersichtlichkeit des Produktionsablaufes und erhöhen die Unfallgefahr. Bei Reihenmaschinen ergibt sich als zusätzlicher Nachteil, daß die unterschiedlichen Temperaturen der durch den Tunnel laufenden Glasgegenstände eine Vergütung nur mit großer Streuung der erzielten Festigkeitswerte zuläßt.Compensation process not possible. Further disadvantages are an increased environmental nuisance caused by the gas flowing out of the openings in the tunnel and production downtimes due to overturned or jammed hollow glass articles which cause hot glasses to jam in or in front of the tunnel. The tunnels used today for the coating of hollow glass objects reduce the clarity of the production process and increase the risk of accidents. In series machines, there is an additional disadvantage that the different temperatures caused by the Glass objects running through tunnels can only be reimbursed if the strength values achieved are widely distributed.

Es ist Aufgabe der Erfindung, diese Nachteile zu vermeiden und eine gleichmäßige Vergütung der produzierten Ware durch eine genauere Zuteilung des Vergütungsmittels bei annähernd gleicher Temperatur der Gegenstände anzustreben.It is an object of the invention to avoid these disadvantages and to strive for a uniform remuneration of the goods produced by a more precise allocation of the remuneration means at approximately the same temperature of the objects.

Dieses Ziel wird durch den Einsatz von Glasformen erreicht, deren mit dem heißen Glas in Berührung kommende Wände aus porösem Werkstoff bestehen, wobei das zur Trennung von Glas und Form benutzte Medium ganz oder teilweise, dauernd oder zeitweise ersetzt wird durch ein Medium, das die Oberfläche des Glases in der gewünschten Weise chemisch und/oder physikalisch beeinflußt.This goal is achieved through the use of glass molds, the walls of which come into contact with the hot glass and are made of porous material, the medium used for separating the glass and mold being replaced in whole or in part, permanently or temporarily by a medium that covers the surface of the glass in the desired manner chemically and / or physically influenced.

Die Vorteile dieser Erfindung sind vor allen Dingen darin zu sehen, daß die Vergütung von Hohlglasgegenständen, gesteuert und genau bemessen, schon in derThe advantages of this invention can be seen above all in the fact that the tempering of hollow glass objects, controlled and precisely measured, already in the

Produktionsmaschine unter Ausschaltung äußerer Einflüss stattfindet. Production machine takes place with the exclusion of external influences.
