Description

Die Erfindung bezieht sich auf eine Spritzpistole zum Versprühen von Farben und ähnlichen viskosen Medien, die pneumatisch oder elektrisch antreibbar ist, bestehend aus einem Pistolengehäuse zur Aufnahme der den Antrieb, die Vermischung und/oder die Dosierung bewirkenden Bauteile der Spritzpistole, einem von dem Pistolengehäuse abstehenden Griffstück und einem an dem Pistolengehäuse abnehmbar befestigten Vorratsbehälter zur Aufnahme des zu verarbeitenden Mediums, wobei dieses über einen vorzugsweise mit einem Steigrohr versehenen Zuführungskanal aus dem Vorratsbehälter in das Pistolengehäuse der Spritzpistole einführbar ist.The invention relates to a spray gun for spraying paints and similar viscous media which is pneumatically or electrically driven, consisting of a gun housing for receiving the drive, the mixing and / or the dosage causing components of the spray gun, a projecting from the gun body Handle and a removably attached to the gun housing reservoir for receiving the medium to be processed, which is introduced via a preferably provided with a riser feed channel from the reservoir into the gun housing of the spray gun.

Spritzpistolen dieser Bauart sind in zahlreichen unterschiedlichen Ausgestaltungen bekannt und haben sich in der Praxis auch bewährt. Um ein Medium verarbeiten zu können, ist bei diesen Spritzpistolen der Vorratsbehälter von dem Pistolengehäuse abzunehmen und dieser ist entsprechend zu befüllen. Dies ist mitunter zeitaufwendig, auch kann Farbe oder ein anderes Medium dabei leicht verschüttet werden. Des Weiteren sind bei einem Wechsel des zu verarbeitenden Mediums oftmals umfangreiche Reinigungsarbeiten unumgänglich, die ebenfalls Zeit in Anspruch nehmen. Vor allem aber ist bei diesen Spritzpistolen von Nachteil, dass die Viskosität des in den Vorratsbehälter eingebrachten Mediums den jeweiligen konstruktiven Figurationen des Spritzgerätes, mittels dem das Medium versprüht werden soll, anzupassen ist. Dies erfordert Sachkenntnis und Geschick. Eine optimale Arbeitsweise ist somit oftmals mit den bekannten Spritzpistolen nicht zu erzielen.Spray guns of this type are known in numerous different configurations and have also proven themselves in practice. In order to be able to process a medium, in these spray guns the reservoir must be removed from the gun body and this must be filled accordingly. This is sometimes time consuming, also color or other medium can be easily spilled. Furthermore, when changing the medium to be processed often extensive cleaning work is inevitable, which also take time. Above all, however, is disadvantageous in these spray guns that the viscosity of the introduced into the reservoir medium to the respective structural Figurationen of the sprayer, by means of which the medium is to be sprayed, is to be adjusted. This requires expertise and skill. An optimal mode of operation is therefore often not possible with the known spray guns.

Aufgabe der Erfindung ist es daher, eine Spritzpistole der vorgenannten Gattung in der Weise auszugestalten, dass an dieser ohne Weiteres und in kurzer Zeit Vorratsbehälter unterschiedlicher Gestaltung betriebssicher angebracht werden können, die mit einem Medium befüllt sind, das an die einzusetzende Spritzpistole und/oder die auszuführenden Arbeiten angepasst ist und unmittelbar nach dem Anbringen an dem Pistolengehäuse verarbeitet werden kann. Rüstzeiten sollen demnach nahezu entfallen, auch sollen keine Reinigungsarbeiten vorzunehmen sein, vielmehr soll nach einem Arbeitsgang der Vorratsbehälter einfach abgenommen und wieder verschlossen werden können.The object of the invention is therefore to design a spray gun of the aforementioned type in such a way that can be attached to this easily and in a short time reservoir of different design reliable, which are filled with a medium to be used to the spray gun and / or is adapted to work to be performed and can be processed immediately after attachment to the gun body. Set-up times are therefore almost eliminated, and no cleaning should be done, but should be easily removed after a single operation of the reservoir and closed again.

Gemäß der Erfindung wird dies bei einer Spritzpistole der vorgenannten Art dadurch erreicht, dass der Vorratsbehälter als ein an die Spritzpistole angepasstes und auf diese abgestimmtes Aufnahmebehältnis, insbesondere in Form einer speziellen Farbdose oder eines Farbbeutels,ausgebildet ist und dass das Aufnahmebehältnis unmittelbar an einem vorzugsweise als Deckel oder Platte gestalteten durch einen Steg an dem Pistolengehäuse und/oder durch einen Steg an dem Griffstück gehaltenen Ansatzstück oder mittels an dem Ansatzstück abgestützter Spannglieder an diesem befestigbar ist.According to the invention, this is achieved in a spray gun of the aforementioned type in that the reservoir is designed as a matched to the spray gun and adapted to this receptacle, in particular in the form of a special paint can or a color bag, and that the receptacle directly to a preferably as Lid or plate designed by a web on the gun body and / or by a web on the handle held extension piece or by means of the extension piece supported tendons can be attached thereto.

In einfacher Ausgestaltung kann das Aufnahmebehältnis in Form einer metallischen Farbdose ausgebildet und mittels eines in deren der Dosenöffnung zugeordneten Randbereich vorgesehenen unmittelbar in ein in dem Ansatzstück vorgesehenes Innengewinde einschraubbar sein.In a simple embodiment, the receptacle may be formed in the form of a metallic paint can and be screwed by means provided in the edge opening of the associated can opening directly into a provided in the extension female thread.

Nach einer andersartigen Ausführung kann das Aufnahmebehältnis in seinem dem Ansatzstück zugekehrten Endbereich mit einem radial überstehenden Bund versehen sein, das Ansatzstück kann ein Innengewinde aufweisen und zur Verspannung des Aufnahmebehältnisses mit dem Ansatzstück kann ein als Spannring ausgebildetes Spannglied vorgesehen sein, das unmittelbar oder mittels radial nach innen abstehender auf den Bund einwirkender Spannarme gegen das Ansatzstück und/oder eine in dieses eingesetzte Dichtung pressbar ist.According to another embodiment, the receptacle may be provided in its end piece facing the end portion with a radially projecting collar, the extension piece may have an internal thread and for clamping the receptacle with the extension piece may be provided as a clamping ring clamping member may be provided directly or by means of radially inside projecting on the collar acting clamping arms against the extension piece and / or a seal used in this is pressed.

Das zur Verspannung des Aufnahmebehältnisses vorgesehene Spannglied kann auch als Hohlkörper zur Aufnahme des Aufnahmebehältnisses ausgebildet sein.The tensioning of the receptacle provided clamping member may also be formed as a hollow body for receiving the receptacle.

Nach einer Weiterbildung ist vorgesehen, das Aufnahmebehältnis mit einem vorzugsweise zentrisch angeordneten und in eine in dessen Boden eingeformte Vertiefung eingreifenden Steigrohr zu versehen, das unmittelbar an dem Verschlussdeckel des Aufnahmebehältnisses angeformt und in das das Steigrohr der Spritzpistole beim Anschluss des Aufnahmebehältnisses an diese einführbar ist, wobei das Aufnahmebehältnis mit einem oder mehreren lose eingelegten Mischkörpern versehen sein sollte.According to a further development, it is provided to provide the receptacle with a preferably centrally arranged and engaging in a recess formed in the bottom recess riser, which is formed directly on the closure lid of the receptacle and in which the riser of the spray gun when connecting the receptacle to this is inserted wherein the receptacle should be provided with one or more loosely inserted mixed bodies.

Zum Ausgleich unterschiedlicher Höhen von Aufnahmebehältnissen ist es angezeigt, ein oder mehrere auf diese aufrastbare Fußstücke vorzusehen, mittels denen die Standfläche des Aufnahmebehältnisses an die Standfläche des Griffstückes anpassbar ist, es ist aber auch möglich, das Aufnahmbehältnis in seiner Höhe auf die Standfläche des Griffstücks abzustimmen oder das Griffstück derart in seiner Lage veränderbar zu gestalten, dass die Standflächen des Aufnahmebehältnisses und des Griffstückes in einer Ebene verlaufen.To compensate for different heights of receptacles, it is appropriate to provide one or more aufrastbare this foot pieces, by means of which the footprint of the receptacle is adaptable to the footprint of the handle, but it is also possible to tune the receptacle in its height to the base of the handle or to make the handle so changeable in its position that the base surfaces of the receptacle and the handle extend in a plane.

Nach einer weiteren Ausführungsvarianten kann das Vorratsbehältnis aus einem elastisch verformbaren Beutel aus einem elastischen Kunststoffwerkstoff als Aufnahmebehältnis bestehen, der in dem dem Ansatzstück des Pistolengehäuses zugekehrten Ende mit einem stabilen planen Abschlussflansch versehen ist, und der Beutel sollte in einen Stützkörper eingesetzt sein, der mittels eines in dessen oberen Endbereich vorgesehenen Außengewindes in ein in dem Ansatzstück vorgesehenes Innengewinde einschraubbar und zwischen dem Stützkörper und dem Ansatzstück sollte ein überstehender Rand des Abschlussflansches einspannbar sein.According to a further embodiment, the storage container may consist of an elastically deformable bag made of an elastic plastic material as a receptacle, which is provided in the end of the gun body end piece with a stable flat end flange, and the bag should be inserted into a supporting body by means of a in the upper end region provided external thread in a provided in the extension female thread and between the support body and the extension piece should be a projecting edge of the end flange can be clamped.

Bei einer durch Druckluft betätigbaren Spritzpistole ist es angebracht, den Innenraum des Beutels und/oder den Raum zwischen dem Stützkörper und dem Beutel über gesonderte Kanäle an den Luftführungskanal im Pistolengehäuse der Spritzpistole anzuschließen, so dass durch den sich aufbauenden Luftdruck das zu verarbeitende Medium dem Pistolengehäuse zugeführt wird.In an air operated spray gun, it is appropriate, the interior of the bag and / or the space between the support body and the bag via separate channels to the air duct in the gun body of the spray gun connect, so that the medium to be processed is supplied to the gun housing by the building up air pressure.

Zweckmäßig ist es des Weiteren, das Steigrohr z.B. mittels Ansatzstücken oder Zwischenstücken in seiner Länge an die Höhe des Vorratsbehältnisses anzupassen und das Aufnahmebehältnis jeweils über eine plattenförmig ausgebildete Dichtung an dem Ansatzstück abzustützen, die mit zumindest einer in Richtung des Aufnahmebehältnisses abstehenden umlaufenden Dichtlippe versehen sein sollte, die innen am Rand der Öffnung des Aufnahmebehältnisses anliegen sollte.It is furthermore expedient to connect the riser pipe, e.g. to adapt by means of lugs or spacers in its length to the height of the storage container and the receptacle each support a plate-shaped seal on the extension piece, which should be provided with at least one circumferential sealing lip projecting in the direction of the receptacle inside the edge of the opening of the receptacle should be present.

Wird eine Spritzpistole gemäß der Erfindung ausgebildet, so ist es möglich, auf sehr einfache Weise und in kurzer Zeit gesonderte auch in der Gestaltung und den Abmessungen sehr unterschiedliche Aufnahmebehältnisse an dem Pistolengehäuse anzubringen, die ein zur unmittelbaren Verarbeitung vorgesehenes Medium enthalten können. Vorbereitende Arbeiten, wie z.B. die Einstellung der Viskosität, sind demnach nicht mehr erforderlich, vielmehr kann das zu verarbeitende Medium bereits bei der Herstellung optimal auf das jeweilige Arbeitsgerät und den Verwendungszweck abgestimmt werden.If a spray gun according to the invention is formed, then it is possible to attach in a very simple manner and in a short time separate also in the design and dimensions very different receptacles on the gun body, which may contain a provided for immediate processing medium. Preparatory work, such as the adjustment of the viscosity, are therefore no longer necessary, but the medium to be processed can be optimally matched to the particular working device and the intended use already during production.

Des Weiteren ist von Vorteil, dass bei Verwendung der vorschlagsgemäß gestalteten Spritzpistole nahezu keine Umfüllungen des zu verarbeitenden Mediums und/oder Reinigungsarbeiten vorzunehmen sind. Das Aufnahmebehältnis kann nämlich unmittelbar nach Beendigung eines Arbeitsvorganges leicht von dem Pistolengehäuse abgenommen und gegebenenfalls mit dem Originaldeckel verschlossen oder entsorgt werden. Rüstzeiten entfallen somit nahezu vollständig. Bei einfacher Handhabung wird auf diese Weise das Verarbeiten von Medien unterschiedlicher Konsistenz ohne zusätzlichen Arbeitsaufwand in einem erheblichen Maße erleichtert.Furthermore, it is advantageous that, when using the spray gun of the proposed design, virtually no transfers of the medium to be processed and / or cleaning work are to be carried out. The receptacle can namely easily removed immediately after completion of a procedure from the gun body and optionally closed or disposed of with the original cover. Set-up times are thus almost completely eliminated. With easy handling, the processing of media of different consistency is facilitated in this way to a considerable extent without additional work.
