Description

Verfahren zum Auftragen einer Schutzschicht auf die Innenseite von Blechdosenrümpfen Die Erfindung betrifft ein Verfahren zum Auftragen einer Schutzschicht .auf die Innenseite von Blechdo-senrümpfen, mit dessien Hilfe ,es möglich ist, eine außerordentlich große Anzahl von Dosenrürmpfen im Dauerbetrieb schnell, sicher und gleichmäßig auf der Innenseite mit einem Streifen Lack o. dgl. * zu versehen. Das neue Verfahren, das ;auch auf Dosenrümpfe anwendbar ist, _die bis ,auf die Längsnaht innen bereits mit einer Schutzschicht ausgekleidet sind, besteht darin, daß die Dosenrümpfe in Achsenrichtung mit Abständen über einen an der Unterseite eine vorstehende Auftragsbürste o. dgl. aufweisenden Dorn geführt werden, und daß. die Schutzschichtmasse fortlaufend ,an die Auftragsbürste durch eine diese Bürste berührend;, umlaufende, parallel. unter dem Dorn angeordnete und in einen Vorratsbehälter @eintauchende, schraubenförmig gestaltete Streichleiste o. dgl. übertragen wird, wobei diese Streichleiste mit einer solchen Geschwindigkeit in Drehung versetzt wird, daß ihre Berührungsstelle mit der Bürste während des Betriebes stets zwischen zwei aufeinanderfolgenden, auf dem Dorn verschiebbaren Dosenrümpfen liegt und mit diesen entsprechend mitwandert.Method of applying a protective layer to the inside of Tin can bodies The invention relates to a method for applying a protective layer .on the inside of tin can bodies, with the help of which it is possible to create a extremely large number of can bodies in continuous operation quickly, safely and to be provided evenly on the inside with a strip of lacquer or the like *. That new process, which; can also be used on can bodies, _the up to, on the longitudinal seam are already lined inside with a protective layer, is that the Can bodies in the axial direction with spacings over a protruding one on the underside Application brush o. The like. Having mandrel are performed, and that. the protective layer mass continuous, touching the application brush with one of these brushes;, circumferential, parallel. arranged under the mandrel and immersed in a storage container @, Helical shaped squeegee or the like is transferred, this squeegee is set in rotation at such a speed that their point of contact with the brush during operation always between two consecutive ones the mandrel is displaceable can bodies and moves with them accordingly.

In Fig. r der Zeichnung ist ein Teil des Dosenrumpfes dargestellt, der .auf der Innenseite nur bis zu den Linien a reichenden Schutzschicht b versehen ist. Zwischen den Linien a liegt die durch die ineinander verfalzten Blechkanten gebildete Längsnaht c, .die nach dem neuen Verfahren mit einem Schutzschichtstreifen versehen werden soll. Dabei ist der Schutzschichtstreifen so breit zu wählen, daß er bis zu den Linien ,a reicht.In Fig. R of the drawing part of the can body is shown, the .on the inside only up to the lines a reaching protective layer b provided is. Between the lines a lies the sheet metal edges folded into one another formed longitudinal seam c,. die after the new process with a protective layer strip should be provided. The protective layer strip is to be chosen so wide that he reaches to the lines, a.

In den Fig.2 und 3 der Zeichnung ist in Seitenansicht und im Schnitt nach der Linie 3-1 aus Fig. 2 eine zur Ausübung des neuen Verfahrens geeignete Vorrichtung als Beispiel dargestellt.In FIGS. 2 and 3 of the drawing, a device suitable for carrying out the new method is shown as an example in a side view and in section along the line 3-1 from FIG.

Mit d ist ein Dorn bezeichnet, über denz. B. aus Schwarzblech hergestellte Dosenrümpfe e in gewissen Abständen durch einen Mitnehmerförderer f, g fortlaufend vorwärtsgeschoben werden. In einer Aussparung h an der Unterseite des Dornes d ist :eine Bürstz i eingesetzt, deren Borsten k über die untre Begrenzung des Dornes.(I um ein Geringes vorstehen.A mandrel is designated by d, over which. B. can bodies made of black plate e are continuously pushed forward at certain intervals by a driver conveyor f, g . In a recess h on the underside of the mandrel d: a brush i is inserted, the bristles k of which protrude slightly beyond the lower limit of the mandrel (I).

Parallel zu dem Dorn d und unter diesem ist eine Auftragsvorriehtung angeordnet, die aus einer .auf einer Welle it befestigt°n" schraubenförmig gestalteten Streichleiste tn. und aus einem Vorratsbehälter p mit eingefüllter Schutzschichtmasse o besteht. Durch eine Kette g wird die Wellen der Streichleistern in Drehung versetzt, und zwar mit einer solchen Geschwindigkeit, daß die Berührungsstelle zwischen der Streichleiste in und den Borsten k der Bürstet sich stets zwischen zwei aufeinanderfolgenden, über der. Dorn #-l verschiebbaren Dosenrümpfen e befindet und mit diesen entsprechend mitwandert. Die von der Streichleiste »t mitgenommene Sehutzschichtmasse wird auf die Unterseite der Borsten k aufgetragen und von diesen an die Innenseite der vorbei@vandzrnden Dosenrümpfee in Form eines Streifens abgegeben.In parallel with the mandrel d and below it is an order device arranged, which is formed from a .on a shaft it attached ° n "helical Squeegee tn. and from a storage container p with a protective layer compound filled in o exists. The shafts of the coating strips are set in rotation by a chain g, and with such a speed that the point of contact between the The brushing strip in and the bristles k the brush is always between two successive, above the. Dorn # -l displaceable can bodies e located and with these accordingly migrates with. The protective layer mass carried along by the trowel is on applied to the underside of the bristles k and from these to the inside of the past @ vandzrnden Canned body delivered in the form of a strip.

Die Breite der Bürste i ii#älilt man entsprechend der Breite des zu erzeug; nden Schutzstreifens in der Dose.The width of the brush is adjusted according to the width of the generate; the protective strip in the can.
