Description

Vorrichtung zum Verbinden der Pechkittklötze mit den zu schleifenden Glasstücken durch Erwärmung. Optische Gläser, die in größerer Anzahl auf Schalen (Köpfen) gemeinsam geschliffen und poliert werden sollen, werden zuvor mit sogenannten Kittklötzen versehen, mittels deren sie an der sogenannten Kittschale befestigt werden.Device for connecting the blocks of pitch cement with those to be ground Glass pieces by heating. Optical glasses that are placed in large numbers on bowls (Heads) are to be ground and polished together, are beforehand with so-called Provided putty blocks, by means of which they are attached to the so-called putty shell will.

Eines der hierbei am häufigsten angewendeten Verfahren besteht darin, daß man die Gläser auf eine beheizte Platte legt und dann ein Stück Pech auf das Glas bringt; die Wärme der,beheizten Platte bewirkt dann, daß das Pechstück sich innig mit dem Glas verbindet. Hierbei werden jedoch die Gläser häufig übermäßig stark erhitzt, erhalten dadurch Spannung und springen dann bei der späteren Bearbeitung.One of the most common methods used here is to that you put the glasses on a heated plate and then a piece of pitch on the Glass brings; the heat of the heated plate then causes the piece of pitch to move connects intimately with the glass. In doing so, however, the glasses often become excessive strongly heated, thereby receiving tension and then jumping during later processing.

Die vorliegende Erfindung betrifft nun eine Vorrichtung, bei der das Befestigen der Kittklötze am Glas in einer mehr zwangläufigen, kontrollierbaren Art geschieht, die nebenbei das Arbeitsverfahren noch vereinfacht.The present invention relates to a device in which the Attaching the putty blocks to the glass in a more compulsive, controllable manner Art happens, which also simplifies the work process.

Die Vorrichtung besteht aus einer Wärmeplatte w, die irgendwie, z. B. elektrisch oder mit Gas, beheizt wird; über die Platte hin bewegt sich von einem Ende zum andern eine endlose weitmaschige Transportkette k, die in bekannter Weise durch ein Räderwerk angetrieben wird. Die Glieder der Kette bilden auf dem Wärmetisch allseitig begrenzte Abschnitte; Felder, in welche die Arbeiterin die Gläser g mit den lose daraufliegenden Kittklötzen stellt. Die Transportkette nimmt nun diese Gläser bei ihrer Bewegung über den Wärmetisch .mit, und` dieHitze derPlatte und die Schnelligkeit der Kettenbewegung wird so eingerichtet, daß die Kittklötze mit den Gläsern richtig verschmolzen sind, wenn sie das andere Ende der Wärmeplatte erreichen. Hier nimmt eineArbeiterin die fertiggekitteten Gläser von der Wärmeplatte. Man kann natürlich auch eine gewisse Anzahl von Gläsern mit lose daraufliegenden Kittklötzen in flache Kästchen tun und diese dann mit der Transportkette über den Wärmetisch bewegen lassen.The device consists of a heat plate w which somehow, e.g. B. is heated electrically or with gas; moves across the plate from one The end to the other is an endless, wide-meshed transport chain k, which is carried out in a known manner is driven by a gear train. The links of the chain form on the heating table sections delimited on all sides; Fields in which the worker takes the glasses the loose putty blocks on top. The transport chain now takes this Glasses as they move over the heating table .with, and` the heat of the plate and the speed of the chain movement is set up so that the putty blocks with The glasses are properly fused when they reach the other end of the hot plate reach. Here a worker takes the cemented glasses from the hotplate. You can of course also have a certain number of glasses loosely on top Put putty blocks in flat boxes and then use the transport chain over the Let the heat table move.

An Stelle der Transportkette kann selbstverständlich auch irgendein anderes- ähnliches Beförderungsmittel dienen, z. B. ein ,endloses Band laus Metallgeflecht, auf das dann die Gläser mit den Kittklötzen gelegt werden.Instead of the transport chain, any serve other similar means of transport, z. B. an endless band of metal mesh, on which the glasses with the putty blocks are then placed.

Der Wärmetisch mitsamt der Transportvorrichtung kann zweckmäßig mit einer an beiden Enden offenen Haube überdeckt werden, welche die unnötige Wärmestrahlung dämpft und gleichzeitig ermöglicht, den entstehenden Pechdunst abzusaugen.The heating table together with the transport device can expediently with a hood open at both ends to be covered, which prevents the unnecessary heat radiation dampens and at the same time enables the resulting pitch vapor to be sucked off.
