Description
Verfahren und Einrichtung zum innenlackieren von Konservendosen u. dgl. Gefäßen. Das Überziehen des Weißblechs von Konservendosen u. dgl. geschieht bisher gewöhnlich bei unverarbeitetem Blech durch Aufstreichen oder Aufwalzen des flüssigen Lackes, bei gelöteten Rümpfen mit oder ohne Böden aber durch Eintauchen in die Lackflüssigkeit oder durch Spritzen. Das Aufwalzverfahren ist gut, hat aber den Nachteil, daß beim nachträglichen Löten der Lack in der Nähe der Lötstelle verbrennt. Das Eintauchen der Rümpfe ergibt einen guten Lacküberzug, dagegen ist der Lackverbrauch sehr hoch, da die Dosen unnötigerweise auf beiden Seiten lackiert werden. Das allgemein übliche Spritzverfahren hat erhebliche Nachteile, vor allem den, daß der Lacküberzug niemals gleichmäßig ausfällt. Das gleichfalls versuchte Lackieren der Doseninnenflächen durch umlaufende Wischer leidet daran, daß die erforderliche Gleichmäßigkeit des Lacküberzuges auf dem Blech zu wünschen übrig läßt.Method and device for the interior painting of cans and. like vessels. The tinplate of cans and the like is coated hitherto usually on unprocessed sheet metal by brushing or rolling the liquid varnish, but in the case of soldered hulls with or without bottoms by immersion into the paint liquid or by spraying. The roll-on process is good, but has the disadvantage that during subsequent soldering the paint burns near the soldering point. Immersing the hulls results in a good coat of paint, but the paint consumption is on the other hand very high as the cans are unnecessarily painted on both sides. That in general Conventional spraying processes have considerable disadvantages, especially that the paint coating never turns out evenly. The also attempted painting of the inside of the can by rotating wiper suffers from the fact that the required evenness of the Lacquer coating on the sheet leaves something to be desired.
Den geschilderten Mängeln abzuhelfen, ist die Erfindung bestimmt, die gewissermaßen eine kleine Druckmaschine im Innern des gelöteten Rumpfes arbeiten läßt, um durch unmittelbares Auftragen die Innenseite leerer Dosen mit oder ohne Böden mit einer Lack-oder Farbschicht zu versehen.To remedy the deficiencies described, the invention is intended to which, as it were, work a small printing machine inside the soldered hull lets you apply directly to the inside of empty cans with or without To provide floors with a layer of lacquer or paint.
Auf der Zeichnung ist die Erfindung beispielsweise veranschaulicht :durch einen Querschnitt, Abb. r, einen teilweisen Längsschnitt, Abb. z.The invention is illustrated by way of example in the drawing : through a cross-section, fig. r, a partial longitudinal section, fig. z.
Über fliegend gelagerte Walzen wird die zu behandelnde Dose gestülpt. Die eine der Walzen, s, eine Stahlwalze, entnimmt den Lack einem flachen Trog t, um die benachbarte Gummiwalze g, wie bei einer Druckmaschine, mit einer dünnen Lackschicht zu versehen. Eine dritte äußere Walze a, die mittels eines Hebels lc verstellbar ist, drückt die Innenseite der Dose d fest gegen die Gummiwalze g. Werden die Walzeng, s zwangläufig von außen her umgetrieben, so läuft der Dosenrumpf um und wird innen gleichmäßig mit einer Lackschicht überzogen.The can to be treated is placed over overhung rollers. One of the rollers, s, a steel roller, takes the paint from a shallow trough t, around the neighboring rubber roller g, like on a printing machine, with a thin layer of varnish to provide. A third outer roller a, which is adjustable by means of a lever lc is, the inside of the can d presses firmly against the rubber roller g. Will the rollers s inevitably driven around from the outside, so the can body revolves and becomes inside evenly coated with a layer of varnish.
Nach Abheben der Walzea läßt sich die behandelte Dose entfernen und durch eine andere ersetzen usf.After lifting off the roller, the treated can can be removed and replace with another, etc.
