Description

Die Erfindung bezieht sich auf solche Spritzapparate für Malerarbeiten, bei denen ein Tropfenfänger und eine Farbrücklaufleitung zum Farbbehälter vorhanden ist. Es gibt Tropfenfänger an Spritzapparaten, die aus einer senkrecht zum Farbstrahl stehenden Wand gebildet werden, in welcher sich eine zentrale Öffnung befindet. Mit diesem nach Art eines Auffangschildes wirkenden Tropfenfänger wird erreicht, daß nur der mittlere Teil des Farbstrahles frei austreten kann. Die Tropfen, die im Streukegel entstehen, fallen zu Boden. Der Zweck dieser bekannten Vorrichtung ist, einen stets gleichbreiten Streifen zu erhalten. Bekannt sind auch Spritzapparate mit Tropfenfänger zum Auffangen der aus dem Farbröhrchen überquellenden Tropfen. Gegenüber den bekannten Vorrichtungen besteht die vorliegende Erfindung darin, daß in der Richtung der Streukegelachse ein den Streukegel fast in seiner ganzen Länge umgebender Mantel verstellbar und abnehmbar angeordnet ist. In diesem Mantel werden alle innerhalb des Streukegels sich bildenden größeren Tröpfchen abgefangen, da sie infolge ihrer Schwere nicht mehr wie die zerstäubten, feinen Farbteilchen von der Luft getragen werden. Die beim Arbeiten mit Farbzerstäubern ohne Tropfenfänger durch die Tropfen entstehenden Verunreinigungen werden somit gemäß der Erfindung durch das Auffangen der Farbentropfen vermieden. Die Tropfenbildung im Streukegel eines Farbzerstäubers kann aus verschiedenen Ursachen sehr stark auftreten.The invention relates to such spray guns for painting, in which a drip catcher and a paint return line to the paint container are available. It are drip catchers on spray guns, which are perpendicular to the paint jet Wall are formed in which there is a central opening. With this after Type of a collecting shield acting drip catcher is achieved that only the middle one Part of the ink jet can escape freely. The drops that appear in the scattering cone fall to the ground. The purpose of this known device is to always have a strip of the same width to obtain. Also known are spray guns with drip catchers to collect the out drops overflowing the paint tube. Compared to the known devices, the present invention is that in the direction of the axis of the scattering cone, it surrounds the scattering cone over almost its entire length Coat is adjustable and removable. In this mantle all that are formed within the scattering cone are larger droplets are caught, because due to their weight they no longer atomize like the ones fine paint particles are carried by the air. The one when working with paint atomizers Without a drip catcher, impurities arising from the drops are thus avoided according to the invention by collecting the paint drops. the Droplet formation in the scattering cone of a paint atomizer can have various causes occur very strongly.

Auf der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform dargestellt.The subject of the invention is shown in an exemplary embodiment in the drawing shown.

Der mit einem Handgriff versehene Farbbehälterkopf e trägt einen Fuß /, an welchem das Luftrohr g wie auch das Farbrohr h verstellbar befestigt sind. Der fest oder verstellbar und lösbar angebrachte Tropfenfänger hat die Form eines kreisförmigen Mantels a, der in Richtung der Streukegelachse liegt, den Streukegel umschließt und fast die ganze Länge des Streukegels einnimmt. Der Mantel α hat vorn einen nach innen gerichteten Bordrand b. Unter dem inneren Ende des Mantels α befindet sich eine Schale c zum Aufnehmen der zurücklaufenden Farbe, die von dieser durch mehrere Rohrstutzen d in den Flüssigkeitsbehältern zurückgeleitet wird. Diese Vorrichtung hat außer der Reinlichkeit auch noch den hauptsächlichen Vorteil, daß sehr viel an Flüssigkeitsmaterial gespart wird, weil ein Abtropfen nicht mehr vorkommen kann. Außerdem bringt diese Vorrichtung den Vorteil einer gleichmäßigen Spritzarbeit mit sich, weil durch die Öffnung des Rohr-Stutzens α hindurch sich nur die Kernpartie des Streukegels, welche eine gleichmäßig feine Zerstäubung auf die zu bespritzende Fläche oder Gegenstand abgibt, auswirken kann. Die Farbauffang- und Rückleitung in den Behälter ist so angebracht, daß man mit dem Apparat ohne irgendwelche Umstellung auch in die Höhe spritzen kann, was bei der Dekorationsmalerei besonders wertvoll in Erscheinung tritt. The paint container head e , which is provided with a handle, carries a foot / to which the air tube g as well as the paint tube h are adjustably attached. The fixed or adjustable and detachable attached drip catcher has the shape of a circular jacket a, which lies in the direction of the scattering cone axis, encloses the scattering cone and takes up almost the entire length of the scattering cone. The jacket α has an inwardly directed rim b at the front. Under the inner end of the jacket α is a bowl c for receiving the returning paint, which is returned from this through a plurality of pipe sockets d in the liquid container. In addition to its cleanliness, this device also has the main advantage that a great deal of liquid material is saved because dripping can no longer occur. In addition, this device has the advantage of uniform spraying because only the core part of the scattering cone, which emits an evenly fine atomization on the surface or object to be sprayed, can have an effect through the opening of the pipe socket α. The paint collection and return line in the container is attached in such a way that the apparatus can also be used to spray upwards without any adjustment, which is particularly valuable in decorative painting.
