Description
Rotierender Zweikomponentensprühkopf für elektrostatische Lackiervorrichtungen Die Erfindung betrifft einen rotierenden Zweikomponentensprühkopf für elektrostatische Lackiervorrichtungen mit getrennten Zuführungen der Komponenten.Rotating two-component spray head for electrostatic painting devices The invention relates to a rotating two-component spray head for electrostatic Painting devices with separate feeds for the components.
Ein bekannter Sprühkopf besteht aus einer Scheibe, die um eine lotrechte oder etwas gegen die Lotrechte geneigte Achse rotiert. Die eine Lackkomponente wird der Oberseite, die andere Lackkomponente der Unterseite der Sprühscheibe zugeführt, so daß die beiden Komponenten sich erst an der scharfen Sprühkonte vereinigen. Der Förderweg der zu lackierenden Werkstücke ist um die Sprühscheibe herumgeführt.A well-known spray head consists of a disk around a vertical or something rotates against the perpendicular axis. The one paint component will the top, the other paint component is fed to the bottom of the spray disc, so that the two components only combine at the sharp spray profile. Of the The conveying path of the workpieces to be painted is guided around the spray disc.
Mit dieser Anordnung bereitet es Schwierigkeiten, Werkstücke von oben her zu lackieren, auch dann, wenn man eine Sprühglocke der bekannten Art verwenden würde, deren Innenseite die eine Lackkomponente, deren Außenseite die andere Lackkomponente zugeführt wird.With this arrangement, it is difficult to get workpieces from above to paint, even if you use a spray bell of the known type the inside of which would be one lacquer component, the outside of which the other lacquer component is fed.
Diesem Mangel wird erfindungsgemäß dadurch abgeholfen, daß der Sprühkopf aus zwei mit derselben Drehzahl rotierenden gleichartigen Sprühglocken besteht, von denen die eine gleichachsig innerhalb der anderen angeordnet ist und jede eine Zuführung für eine der Komponenten aufweist.This deficiency is remedied according to the invention in that the spray head consists of two spray bells of the same type rotating at the same speed, one of which is coaxially arranged within the other and each one Having feed for one of the components.
Die beiden Lackkomponenten vereinigen sich erst am Werkstück oder auf ihrem Fluge dorthin. Das letzte geschieht um so früher, je kleiner der Unterschied der Glockendurchmesser ist. Da die Umfangsgeschwindigkeiten der beiden Glocken nicht zu sehr voneinander abweichen sollen, ist auch aus diesem Grunde ein nicht zu großer Unterschied der Glockendurchmesser erwünscht.The two paint components only combine on the workpiece or on their flight there. The smaller the difference, the earlier the latter happens is the bell diameter. Since the peripheral speeds of the two bells are not should deviate too much from one another is, for this reason too, not too great Difference in bell diameter is desirable.
Es ist zweckmäßig, wenn sich die beiden Glocken axial etwas gegeneinander einstellen lassen. Auf diese Weise kann man den Sprühkopf an die Eigenschaften der jeweils verwendeten Lacke bzw. ihrer Komponenten anpassen.It is useful if the two bells are axially slightly opposite one another have it adjusted. In this way you can adjust the properties of the spray head Adapt the lacquers used or their components.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.
Die Sprühglocke besteht aus der größeren Glocke 2 und -der kleineren Glocke 3, die beide mittels weniger Stege 4 starr miteinander verbunden sind. Die eine Lackkomponente fließt der äußeren Glocke 2 durch ein Rohr 5, die andere Lackkomponente der inneren Glocke 3 durch ein Rohr 6 zu. Die Sprühkanten 21 und 22 der beiden Glocken 2 und 3 liegen in derselben zur Glockenachse 1 senkrechten Ebene, können aber auch in verschiedenen Ebenen eingestellt werden. Dazu ist eine axiale Verschiebbarkeit der Glocken 2 und 3 gegeneinander dadurch möglich, daß man den Hals der inneren Glocke 3 zweiteilig ausführt und beide Teile je mit einem Gewinde (Innen- und Außengewinde) versieht.The spray bell consists of the larger bell 2 and the smaller one Bell 3, both of which are rigidly connected to one another by means of fewer webs 4. the one paint component flows from the outer bell 2 through a pipe 5, the other paint component the inner bell 3 through a pipe 6 to. The spray edges 21 and 22 of the two bells 2 and 3 lie in the same plane perpendicular to the bell axis 1, but they can also can be set in different levels. There is also an axial displaceability the bells 2 and 3 against each other possible by having the neck of the inner Bell 3 is made in two parts and both parts each with a thread (internal and external thread) provides.
Die Öffnungen zwischen den Stegen 4 sind möglichst groß gehalten, damit die Zufuhr der Lackkomponente zur äußeren Glocke 2 nicht behindert wird.The openings between the webs 4 are kept as large as possible, so that the supply of the paint component to the outer bell 2 is not hindered.
