Description

Die Erfindimg betrifft eine Vorrichtung zum Aufbringen von Schutzüberzügen aus Lack ο. dgl. ,auf die Längsnähte im Innern von Konservendosenrümpfen. The invention relates to a device for applying protective coatings made of paint ο. Like., on the longitudinal seams inside the can bodies.

Um die durch eine Fördervorrichtung auf einem Dorn vorwärts bewegten Dosenrümpfe während ihres Vorwärtsschiebens schnell mit Schutzüberzügen ,auf den Längsnähten im Innern versehen zu können, ist gemäß der Er-Around the can bodies moved forward by a conveyor on a mandrel quickly with protective covers on the longitudinal seams in the To be able to provide the inside is according to the

ό findung in dem Dorn auf der Unterseite eine Aussparung für eine schwenkbar gelagerte Auftragsrolle derart angeordnet, daß sie durch ihr Gewicht beim Vorbeiwandern eines Rumpfes innen auf dessen Innennaht entlangό finding in the spike on the underside of a Recess for a pivotally mounted application roller arranged so that it goes through their weight when walking past a fuselage along the inside of the inner seam

'5 rollt, -und außerhalb der Bewegungsbahn der Dosenrümpfe ist eine Zubringevorrichtung vorgesehen, auf die sich die Auftragsrolle in den Zwischenräumen zwischen je zwei aufeinanderfolgenden Rümpfen abstützt, wodurch die Lackübertragung von der Zubringevorrichtung auf die Auftragsrolle erfolgt.'5 rolls, -and outside the path of movement of the can body is a feeding device provided on which the application roll in the spaces between two consecutive Supports hulls, whereby the paint is transferred from the feeder to the application roll.

Es ist zweckmäßig, die Zubringerolle anzutreiben, damit sie während der Berührung mit der Auftragsrolle diese in Drehung versetzen und auf ihrem Umfang mit genügend Auftragslack versehen kann. Sobald die Auftragsrolle beim Vorwärtsbewegen eines Dosenrumpfes durch diesen angehoben wird, legt sie sich auf die Innenseite der Längsnaht und überzieht diese mit der Schutzschicht.It is convenient to drive the feed roller so that it is in contact set it in rotation with the application roll and with enough on its circumference Can provide application paint. As soon as the application roll when moving a can body forward is lifted by this, it lies on the inside of the longitudinal seam and covers this with the protective layer.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

In einer Maschine zur Herstellung von Dosenrümpfen, wie sie beispielsweise für die Anfertigung von Konservendosen Anwendung findet, ist ein sog. schwebender Dorn 1 angeordnet, auf dem die fertigen Rümpfe 2 mit Abständen voneinander mittels einer Förder-In a machine for the production of can bodies, such as those used for the Production of cans is used, a so-called floating mandrel 1 is arranged, on which the finished hulls 2 are spaced apart by means of a conveyor

vorrichtung 3, 4 vorwärts geschoben werden. Der schwebende Dorn 1, der in bekannter Weise von abwechselnd gehobenen und senkten Tragbolzen gehalten wird, besteig der Lackierstation lediglich aus einem arm 5, an dessen Unterseite 6 zwei Auft: rollen 7 angeordnet sind.device 3, 4 are pushed forward. The floating mandrel 1, known in Way is held by alternately raised and lowered support bolts, climb the painting station only consists of an arm 5, on the underside 6 of which two Auft: rollers 7 are arranged.

Diese Auftragsrollen 7 sind mittels Lenker 8 in einigem Abstand voneinander in Augen 9 gelagert. Jede Rolle 7 ist am Umfang mit einer Rille ι ο versehen, die der äußeren Form der Innenseite der Längsnaht in den vorbeiwandernden Dosenrümpfen 2 entsprechend gestaltet ist. Unterhalb der Auftragsrollen 7 ist ein Vorratsbehälter 11 für den Überzugslack o. dgl. vorgesehen. In Lagern 12 eines Vorratsbehälters 11 sind um Zapfen 13 zwei in der Bewegungsrichtung der Dosenrümpfe hintereinanderliegeKde ZubringeiOlIen I4drehbar angeordnet, die mit ihren unteren Hälften in die im Behälter 11 befindliche flüssige Überzugsmasse 'eintauchen. Die beiden Zapfen 13 tragen Kettenräder 15, über die eine gemeinsame Kette 16 zum gleichmäßigen und gemeinsamen Antrieb der Rollen 14 gelegt ist. Die Rollen 14 und 7 liegen in der gleichen Ebene mit der Achse der vorwärts wandernden Dosenrümpfe, wobei die Rollen 7 oberhalb der Rollen 14 so angeordnet sind, daß die Auftragsrollen 7 durch ihr Gewicht auf den Zubringerrollen 14 aufliegen, wenn nicht ein Dosenrumpf zwischen ihnen liegt. Die angetriebenen Zubringerrollen 14, die sich außerhalb der Bewegungsbahn der vorbeiwandernden Dosenrümpfe 2 befinden, übertragen dabei die Überzugsmasse auf die Rollen 7. Sobald ein Dosenrumpf beim Vorwärtswandern mit seinem vorderen Rande die erste Auftragsrolle 7 erreicht, wird diese vonThese application rolls 7 are at a certain distance from one another in eyes 9 by means of links 8 stored. Each roller 7 is provided on the circumference with a groove ι ο that of the outer shape the inside of the longitudinal seam in the can bodies 2 moving past designed accordingly is. Below the application rolls 7 is a storage container 11 for the coating varnish or the like. Provided. In bearings 12 of a storage container 11 are around pin 13 two in The direction of movement of the can bodies can be rotated one behind the other arranged, the lower halves of the liquid in the container 11 Immerse the coating compound '. The two pins 13 carry sprockets 15, over which a common Chain 16 is laid for the uniform and common drive of the rollers 14. The rollers 14 and 7 lie in the same plane with the axis of the forward traveling Can bodies, the rollers 7 being arranged above the rollers 14 so that the application rollers 7 rest on the feed rollers 14 by their weight, if not a can body lies between them. The driven feeder rollers 14, which located outside the path of movement of the can bodies 2 moving past, transferred while the coating mass on the rollers 7. As soon as a can body when moving forward reaches the first application roller 7 with its front edge, this is of

der zugehörigen Zubringerrolle 14 abgehoben, und sie legt sich von innen an die Dosennaht an. Beim Vorbeiwandern eines Rumpfes 2 rträgt diese Rolle 7 den auf ihren Um-',ng aufgetragenen Überzugsstoff auf die osennaht. Der gleiche Vorgang wiederholt sich beim Vorbeigang des Dosenrumpfes 2 an der zweiten Rolle 7, wodurch ein gleichmäßiger dichter Überzug erzielt wird.the associated feeder roller 14 is lifted and it lies against the can seam from the inside at. When a fuselage 2 rbears past, this role 7 carries the on its um- ', ng applied covering material on the sewing seam. Repeat the same process when the can body 2 passes the second roller 7, whereby a more even dense coating is achieved.

Nach dem Überziehen der Dosenrumpfnähte im Innern werden die Dosenrümpfe durch eine 5c endlose Förderkette aus der Vorrichtung entfernt. After the inside of the can body seams have been pulled over the can body through a 5c endless conveyor chain removed from the device.
