Abstract
Description
Die Erfindung betrifft eine Behandlungstrommel zur Aufnahme von Kleinteilen, die einer Flüssigkeitsbehandlung zur Reinigung oder zur Beschichtung in einer Behandlungsmaschine zu unterziehen sind. Es sind hierbei galvanische Beschichtungen und Lackbeschichtungen in gleicher Weise möglich.The The invention relates to a treatment drum for holding small parts, that of a liquid treatment for cleaning or coating in a processing machine to undergo. There are galvanic coatings and Lacquer coatings in the same way possible.

Behandlungstrommeln der vorstehend genannten Art werden üblicherweise in Blechkonstruktionen hergestellt, wobei sowohl der Zylindermantel als auch der Trommelboden aus gelochtem Stahlblech bestehen. Hierbei ist das Lochmuster an die zu behandelnden Kleinteile in der Weise anzupassen, daß die Lochgröße geringer ist als der geringste Querschnitt der Kleinteile. Während bei Flüssigkeitsbehandlungsschritten, wie dem Waschen und dem Entölen, eine relativ geringe Lochgröße weitgehend unproblematisch bleibt, besteht beim Tauchlackieren das Problem, daß kleine Löcher sich zunehmend mit Lack zusetzen können. Einfache Möglichkeiten zum Reinigen der zugesetzten Löcher sind nicht gegeben.treatment drums of the type mentioned above are usually used in sheet metal constructions produced, with both the cylinder jacket and the drum bottom Made of perforated sheet steel. Here is the hole pattern to adjust the small parts to be treated in such a way that the hole size is smaller is considered the smallest cross section of the hardware. While at Liquid treatment steps, like washing and de-oiling, a relatively small hole size largely unproblematic remains, there is the problem with dip coating that small Holes themselves increasingly can clog with paint. Simple possibilities for cleaning the added holes are not given.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine neuartige Behandlungstrommel bereitzustellen, in der ein günstiger Flüssigkeitszutritt durch den Trommelmantel zu den Kleinteilen gegeben ist, wobei eine einfache Reinigung der Trommel möglich sein soll. Die Lösung hierfür besteht in einer Behandlungstrommel der eingangs genannten Art, umfassend einen Trommelboden und einen flüssigkeitsdurchlässigen Trommelmantel, wobei der Trommelmantel aus parallelen ringförmig auf dem Trommelboden angeordneten Stäben sowie einem ringförmigen mit den Stäben verbundenen oberen Trommelrand besteht. Bevorzugt ist vorgesehen, daß die Zwischenräume zwischen den Stäben durch eine Gitterstruktur abgedeckt sind. Hierzu ist insbesondere vorgesehen, daß ein zylindrischer Gittereinsatz in Anlage mit den Stäben innen in den Trommelmantel eingesetzt ist. Der erfindungsgemäße Trommelmantel aus parallel angeordneten Stäben neigt viel weniger als Lochblechstrukturen zum Zusetzen, da sich zwischen den Stäben Schlitze großer Erstreckung ausbilden. Bei der Verwendung von Kleinteilen geringer Größe wird bevorzugt der Zwischenraum zwischen den Stäben durch eine Gitterstruktur abgedeckt, wobei ein zylindrischer Gittermantel außen um die Stäbe herumgelegt sein kann oder aber bevorzugt innen in Anlage mit den Stäben in den Zylindermantel eingesetzt wird. Hierbei kann sich unter Fliehkrafteinfluß der Gittereinsatz an die Stäbe anlegen. Der Gittereinsatz kann einen eigenen Gitterboden aufweisen, der auf dem Trommelboden aufliegt. Um ein gutes Umwälzen bei gegebenenfalls schräggestellter Trommel sicherzustellen und ein Festhaken von Kleinteilen im unteren Kantenbereich der Trommel zu vermeiden ist insbesondere vorgesehen, daß ein Übergangsbereich vom zylindrischen Trommelmantel zum Trommelboden hin ausgeführt ist, bevorzugt ein Konusbereich oder ein gerundeter Übergang. Ein konischer Übergangsbereich kann vorzugsweise mit radial angeordneten Keilen außen abgestützt sein, die sich innen an einzelne Gitterstäbe anlegen oder mit diesen fest verbunden sind. Der für die Handhabung der Trommel durch Greifermittel notwenige obere Trommelrand ist vorzugsweise durch ein nach außen offenes zu einem Kreis gebogenen U-Profil gebildet, mit dem die oberen Enden der Gitterstäbe fest verbunden sind. Sofern die Trommel am unteren Rand gehalten und/oder angetrieben wird, kann in Ergänzung ein unterer Trommelrand in gleicher Weise aus einem nach außen offenen zum Kreis gebogenen U-Profil bestehen, der mit einem Trommelboden und/oder den unteren Enden der Gitterstäbe verbunden ist.Of these, The present invention is based on the object, to provide a novel treatment drum in which a cheaper liquid access is given by the drum shell to the small parts, with a easy cleaning of the drum possible should be. The solution for this exists in a treatment drum of the type mentioned, comprising a drum base and a liquid-permeable drum shell, wherein the drum shell of parallel annularly arranged on the drum base rods and an annular associated with the bars upper drum edge exists. It is preferably provided that the spaces between the bars are covered by a grid structure. This is especially true provided that a cylindrical grid insert in contact with the bars inside the drum shell is used. The drum shell of the invention from parallel arranged rods Tends much less than perforated sheet structures to clog, since between the bars Slits big Train extension. Smaller when using small parts Size is Preferably, the gap between the bars through a grid structure covered, wherein a cylindrical grid shell outside the Wrapped around bars can be in or in preference with the bars in the inside Cylinder jacket is used. This can be under the influence of centrifugal lattice use to the bars invest. The grid insert can have its own grid floor, which rests on the drum base. To bring about a good circulation possibly inclined To ensure drum and a hooking of small parts in the bottom To avoid edge region of the drum is provided in particular, that a transitional area is executed from the cylindrical drum shell towards the drum bottom, preferably a cone region or a rounded transition. A conical transition area can preferably be supported externally with radially arranged wedges, which create internal to individual bars or with these firmly are connected. The for the handling of the drum by gripper means necessary upper drum edge is preferably by an outwardly open to a circle curved U-shaped profile, with which the upper ends of the bars are fixed are connected. Unless the drum is held at the bottom and / or can be driven in addition to one lower drum edge in the same way from an outwardly open consist of a circle bent U-profile, with a drum bottom and / or the lower ends of the grid bars is connected.
