Description

Die Erfindung bezieht sich auf eine Schleifvorrichtung zum Planschleifen der Stirnränder an Konservengläsern u. dgl., wobei der auf schraubenförmig gewundenen Druckfedern gebettete Schleifring durch den Gegendruck des Werkstückes solche Bewegungen ausführen kann, die der Flächengestaltung des Stirnrandes entsprechen, so daß es möglich ist, auch solche Gläser bzw. Ränder zu schleifen, die nicht im Winkel von 900 zur Zylinderfläche des Werkstückes stehen. Dadurch wird erreicht, daß derart mißgestaltete Gläser, die bisher als Bruch weggeworfen wurden, als brauchbare Gläser Verwendung finden können.The invention relates to a grinding device for flat grinding the end edges of canning jars and the like, whereby the slip ring, which is mounted on helically wound compression springs, can execute movements due to the counterpressure of the workpiece which correspond to the surface design of the end edge, so that it is also possible to grind such glasses or edges that are not at an angle of 90 ° to the cylindrical surface of the workpiece. It is thereby achieved that such misshapen glasses, which were previously thrown away as breakage, can be used as usable glasses.

Schleifvorrichtungen zum Schleifen der Mündungsränder an Konservengläser, bei denen das Werkstück universal gelagert ist und sich schräg einstellen kann, sowie auch solche Einrichtungen mit elastisch abgefederten Werkzeugen werden als bekannt vorausgesetzt. Diesen an sich bekannten Einrichtungen gegenüber weist der Erfindungsgegenstand gemäß der Erfindung wesent- liehe Verbesserungen und wirtschaftliche Vorteile auf. Durch die eigenartige Lagerung und Anordnung des Schleifringes kann er bei seiner elastischen Beweglichkeit jeder Unebenheit des mißgestalteten ■ Werkstückes folgen und plan schleifen. Des weiteren ermöglicht diese Einrichtung es auch, vier- und mehrspindlige Maschinen zu verwenden, wozu nur eine einzige Arbeitskraft notwendig ist.Grinding devices for grinding the mouth edges of canning jars where the workpiece is stored universally and can be set at an angle, as well as such devices with resiliently sprung tools are assumed to be known. In relation to these per se known devices, the subject matter of the invention has essential borrowed improvements and economic benefits. Due to the strange storage and the arrangement of the slip ring, with its elastic mobility, it can handle any unevenness Follow the misshapen ■ workpiece and grind flat. Furthermore enables this facility also makes it possible to use four-spindle and multi-spindle machines, for which only a single worker is required is.

In der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform veranschaulicht. In the drawing, the subject matter of the invention is illustrated in an exemplary embodiment.

Abb. ι zeigt den Schleifkopf mit dem daran befestigten und federnd angeordneten Schleifring. Fig. Ι shows the grinding head with the attached and resiliently arranged slip ring.

Abb. 2 stellt das Arbeitsstück dar.
Gemäß der Erfindung besteht die Einrichtung aus dem Schleifkopf 1, an dessen Flansch 2 der Schleifringträger 3 befestigt ist. Die zu dem Träger gehörende Muffe 4 ist auf den Bolzen 5 gleitbar gelagert. Zwischen Träger 3 und Muffe 4 werden auf den Bolzen 5 schraubenartig gewundene Druckfedern 6, deren Widerlager die Teile 3 und 4 bilden, angeordnet. Der Schleifring 7 ist mit der Muffe 4 fest verbunden. Um das Schleifgut bequem an die Schleifflächen heranführen zu können, ist in dem Schleifkopf 1 ein Durchbruch 8 vorgesehen.Fig. 2 shows the work piece.
According to the invention, the device consists of the grinding head 1, on the flange 2 of which the slip ring carrier 3 is attached. The sleeve 4 belonging to the carrier is slidably mounted on the bolt 5. Between the carrier 3 and the sleeve 4, helically wound compression springs 6, the abutments of which form the parts 3 and 4, are arranged on the bolts 5. The slip ring 7 is firmly connected to the sleeve 4. In order to be able to bring the material to be sanded comfortably to the sanding surfaces, an opening 8 is provided in the sanding head 1.

Der Vorgang beim Schleifen ist folgender: Das Arbeitsstück wird in ein Spannlager gelegt und darin festgehalten, wobei die zu schleifende Fläche gegen den Schleifring gepreßt wird, so daß dieser unter Einwirkung der Druckfeder nunmehr gegen das festliegende Arbeitsstück drückt. Nachdem die Maschine dann in Gang gesetzt ist, bleibt der Schleifdruck während der ganzen Schleifdauer der gleiche. Eine besondere Bedienung oder Wartung ist hierbei nicht erforderlich, vielmehr kann ein Arbeiter mehrere Maschinen gleichzeitig bedienen.The process of grinding is as follows: The workpiece is placed in a radial insert ball bearing placed and held in it, with the surface to be ground pressed against the slip ring is, so that this under the action of the compression spring now against the fixed Work piece presses. After the machine is started, the grinding pressure remains during the entire grinding time the same. Special operation or maintenance is not required here, rather, one worker can operate several machines at the same time.

Vergleichende Versuche haben ergeben, daß mit der Schleifvorrichtung gemäß der Erfindung, das Vierfache der bisherigen Leistangen anderer Maschinen erzielt wurde.Comparative tests have shown that with the grinding device according to the invention, four times the previous performance of other machines was achieved.
