Description

Spritzpistole spray gun
Die vorliegende Erfindung betrifft eine Spritzpistole zum Abgeben eines Spritzguts, insbesondere eines mit Wasser verdünnbaren und lösungsmittelhaltigen Spritzguts, wie beispielsweise Farben, Lacke, Lasuren, Grundierungen, Beizen, Holzschutzmittel oder dergleichen, umfassend ein Gehäuse, einen an dem Gehäuse angeordneten Handgriff und einen Bedienschalter zum Ein- und Ausschalten der Spritzgutabgabe.The present invention relates to a spray gun for dispensing an injection molding, in particular a water-dilutable and solvent-containing injection molding material, such as paints, varnishes, glazes, primers, stains, wood preservatives or the like, comprising a housing, arranged on the housing handle and a control switch to Switching the spray material dispensing on and off.
Spritzpistolen der eingangs genannten Art sind in verschiedensten Ausgestaltungen erhältlich. Als Spritzverfahren kommt meist das Niederdruck-Spritzverfahren zur Anwendung, bei dem es sich um ein Verfahren handelt, bei dem Spritzgut bei einem geringen Druck von etwa 0,2 bis etwa 0,5 bar und mit einem hohen Luftvolumen ab etwa 200 Liter pro Minute verspritzt wird. Dieses HVLP-Spritzverfahren erreicht wegen des geringen Überspritzens, d.h. wegen seiner geringen Sprühnebelverluste, Beschichtungsgrade bis etwa 65% und ist somit herkömmlichen Verfahren, die Beschichtungsgrade zwischen etwa 20 und etwa 35% erzielen, überlegen. Kennzeichnend für das Verfahren ist der das Spritzgut umgebende Luftkegel, der ein Überspritzen und eine Farbnebelbildung verringert. Damit ergeben sich Vorteile wie Lackeinsparung und geringe Lösungsmittelemissionen, die sich besonders umweltschonend auswirken.Spray guns of the type mentioned are available in various designs. The spraying method used is usually the low-pressure spraying method, which is a method in which sprayed material sprays at a low pressure of about 0.2 to about 0.5 bar and with a high volume of air at about 200 liters per minute becomes. This HVLP spraying process achieves low overspray, i. because of its low spray losses, coating levels up to about 65%, and thus superior to conventional processes that achieve coating levels between about 20 and about 35%. Characteristic of the method is the air surrounding the spray material, which reduces overspray and color fog. This results in advantages such as paint savings and low solvent emissions, which have a particularly environmentally friendly effect.
Fig. 5, bei der es sich um eine perspektivische Ansicht handelt, zeigt beispielsweise eine bekannte Spritzpistole der Firma Wagner, die unter der Handelsbezeichnung W850E vertrieben wird. Diese Spritzpistole, in Fig. 5 mit der Bezugsziffer 100 bezeichnet ist, umfasst ein Gehäuse 102; einen Handgriff 104, der am unteren hinteren Ende des Gehäuses 102 einteilig mit diesem ausgebildet ist; einen Bedienschalter 106, der abwärts aus einer unteren Öff- nung (nicht gezeigt) des Gehäuses 102 vorsteht und von dem Handgriff 104 in horizontaler Richtung beabstandet ist, um einen Freiraum zum Betätigen des Bedienschalters 106 zu belassen; eine Einstelleinrichtung 108 zum manuellen Einstellen der Spritzgutmenge, die von der Spritzpistole 100 pro Zeiteinheit abgegeben werden soll, wobei die Einstelleinrichtung 108 einen drehbaren Regler aufweist, der an der Rückseite des Bedienschalters 106 in dem zwischen dem Bedienschalter 106 und dem Handgriff 104 belassenen Freiraum angeordnet ist; einen Druckluftschlauch 110, welcher der Zufuhr von Druckluft dient und am hinteren Ende des Gehäuses 102 angeschlossen ist; eine Spritzdüse 112, von welcher das Spritzgut abgegeben wird und die am vorderen Ende des Gehäuses 102 angeordnet ist; und einen Spritzgutbehälter 114, der lösbar mit einer Halteeinrichtung 116 verschraubt ist, die einteilig mit dem Gehäuse 102 an der vorderen Unterseite desselben ausgebildet ist.Fig. 5, which is a perspective view, shows, for example, a known spray gun from Wagner, which is sold under the trade name W850E. This spray gun, designated by the reference numeral 100 in FIG. 5, comprises a housing 102; a handle 104 formed integrally therewith at the lower rear end of the housing 102; an operating switch 106 which descends from a lower opening (not shown) of the housing 102 protrudes and is spaced from the handle 104 in the horizontal direction to leave a space for operating the control switch 106; adjuster 108 for manually adjusting the amount of spray to be dispensed by the spray gun 100 per unit time, the adjuster 108 having a rotatable regulator located at the rear of the control switch 106 in the space left between the control switch 106 and the handle 104 ; a compressed air hose 110 which serves to supply compressed air and is connected to the rear end of the housing 102; a spray nozzle 112, from which the sprayed material is discharged and which is arranged at the front end of the housing 102; and a spray container 114 which is detachably bolted to a holding device 116 formed integrally with the housing 102 at the front lower side thereof.
Der in Fig. 5 dargestellte Aufbau der Spritzpistole 100 ist dahingehend von Nachteil, dass der Handgriff 104 von einem Benutzer nur schlecht gegriffen werden kann. Dies liegt zum Teil daran, dass der Handgriff 104 sehr dünn ausgebildet ist, um zu gewährleisten, dass ein Benutzer den Bedienschalter 106 noch mühelos erreichen kann, wozu ein hinreichend großer Freiraum zwischen dem Bedienschalter 106 und dem Handgriff 104 belassen werden muss. Dieselbe Problematik wird noch dadurch verstärkt, dass auch die Einstelleinrichtung 108 in Form des drehbaren Reglers in diesem Zwischenraum angeordnet ist, weshalb der Zwischenraum noch größer ausgebildet werden muss. Insgesamt stellt der in Fig. 5 dargestellte Aufbau der Spritzpistole 100 hinsichtlich Ergonomie und Handhabung der Spritzpistole 100 demnach keine optimale Lösung dar. Ferner sind der Bedienschalter 106, die Einstelleinrichtung 108 und die den Zwischenraum definierenden Wände des Gehäuses 102 derart ausgebildet, dass sie leicht verschmutzen können, und sind zudem nur schlecht zu reinigen. Ausgehend von diesem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, eine Spritzpistole mit einem alternativen Aufbau zu schaffen, welche die zuvor genannten Probleme zumindest teilweise behebt.The structure of the spray gun 100 shown in Fig. 5 is disadvantageous in that the handle 104 can be grasped by a user only poorly. This is in part because the handle 104 is made very thin to ensure that a user can still reach the operating switch 106 effortlessly, for which reason a sufficiently large clearance must be left between the operating switch 106 and the handle 104. The same problem is exacerbated by the fact that the adjusting device 108 is arranged in the form of the rotatable regulator in this space, so the gap must be made even larger. Overall, the structure of the spray gun 100 shown in Fig. 5 in terms of ergonomics and handling of the spray gun 100 is therefore not an optimal solution. Furthermore, the control switch 106, the adjuster 108 and the gap defining walls of the housing 102 are formed so that they easily pollute can, and are also difficult to clean. Starting from this prior art, it is an object of the present invention to provide a spray gun of an alternative construction which at least partially obviates the aforementioned problems.
Offenbarung der ErfindungDisclosure of the invention
Zur Lösung dieser Aufgabe schafft die vorliegende Erfindung eine Spritzpistole mit einem Gehäuse, einem an dem Gehäuse angeordneten Handgriff und einem Bedienschalter zum Ein- und Ausschalten der Spritzgutabgabe. Im Gegensatz zu der in Fig. 5 dargestellten bekannten Spritzpistole ist der Bedienschalter erfindungsgemäß in den Handgriff integriert, so dass Bedienschalter und Handgriff eine gemeinsame Einheit bilden. Entsprechend steht der Bedienschalter einer ergonomischen Ausbildung des Handgriffes in keiner Weise entgegen. Zudem kann ein nach außen offener Zwischenraum zwischen Bedienschalter und Handgriff eliminiert werden, so dass die erfindungsgemäße Spritzpistole weniger verschmutzt und sich einfacher reinigen lässt.To achieve this object, the present invention provides a spray gun with a housing, a arranged on the housing handle and a control switch for switching on and off the spray delivery. In contrast to the known spray gun shown in Fig. 5 of the control switch according to the invention is integrated into the handle, so that control switch and handle form a common unit. Accordingly, the control switch is not contrary to an ergonomic design of the handle in any way. In addition, an outwardly open space between the control switch and the handle can be eliminated so that the spray gun according to the invention is less polluted and easier to clean.
Gemäß einer bevorzugten Ausgestaltung der vorliegenden Erfindung umfasst die Spritzpistole eine Sprüheinheit, welche die Spritzdüse der Spritzpistole umfasst, und eine Verbindungseinrichtung zum lösbaren Verbinden der Sprüheinheit mit dem Gehäuse, wobei der Bedienschalter zumindest in demjenigen Zustand, in dem die Sprüheinheit an dem Gehäuse montiert ist, in den Handgriff integriert ist. Die Trennung der Spritzpistole von dem Gehäuse ermöglicht eine einfachere Reinigung der nach dem Gebrauch der Spritzpistole mit Spritzgut behafteten Sprüheinheit. Zudem besteht nicht die Gefahr, dass das Gehäuse während solcher Reinigungsarbeiten durch Spritzwasser oder dergleichen verschmutzt oder beschädigt wird.According to a preferred embodiment of the present invention, the spray gun comprises a spray unit, which comprises the spray nozzle of the spray gun, and a connecting device for releasably connecting the spray unit to the housing, wherein the control switch, at least in the state in which the spray unit is mounted on the housing, integrated into the handle. The separation of the spray gun from the housing allows easier cleaning of the spraying unit afflicted with sprayed material after use of the spray gun. In addition, there is no risk that the housing is dirty or damaged during such cleaning by splashing water or the like.
Bevorzugt umfasst die Spritzpistole eine Einstelleinrichtung zum manuellen Einstellen der Spritzgutmenge, die von der Spritzpistole pro Zeiteinheit abgegeben werden soll. Eine solche Einstell- einrichtung ermöglicht einen flexibleren Einsatz der Spritzpistole. Die Einstelleinrichtung ist vorteilhaft an dem Handgriff angeordnet, so dass sie für den Benutzer mühelos erreichbar ist, während er den Druckschalter betätigt. Entsprechend kann der Benutzer die pro Zeiteinheit abzugebende Spritzgutmenge während der Handhabung der Spritzpistole ohne Probleme entsprechend der aktuellen Anforderungen regeln.Preferably, the spray gun comprises an adjustment for manually adjusting the amount of spray to be delivered by the spray gun per unit time. Such an adjustment device allows a more flexible use of the spray gun. The adjustment device is advantageously arranged on the handle, so that it is easily accessible to the user while he presses the pressure switch. Accordingly, the user can regulate the quantity of spray material to be dispensed per unit time during the handling of the spray gun without any problems in accordance with the current requirements.
Noch besser ist die Einstelleinrichtung direkt am Bedienschalter positioniert, so dass der Bedienschalter und die Einstelleinrichtung eine gemeinsame Einheit bilden. Dabei ist die Einstelleinrichtung bevorzugt seitlich an einer oder besser noch an beiden Seiten am Bedienschalter vorgesehen, wodurch eine optimale Handhabbarkeit der Einstelleinrichtung erzielt wird.Even better, the setting device is positioned directly on the operating switch, so that the operating switch and the setting device form a common unit. In this case, the adjustment device is preferably provided laterally on one or better still on both sides of the operating switch, whereby an optimal handling of the adjusting device is achieved.
Die Einstelleinrichtung umfasst gemäß einer Variante der vorliegenden Erfindung einen verschiebbaren Regler, der bevorzugt derart positioniert ist, dass er etwa in Abgaberichtung des Spritzguts vor und zurück verstellbar ist. Auf diese Weise wird eine besonders ergonomische Handhabung des verschiebbaren Reglers erzielt .According to a variant of the present invention, the adjusting device comprises a displaceable regulator, which is preferably positioned such that it can be adjusted back and forth approximately in the dispensing direction of the injection molding material. In this way, a particularly ergonomic handling of the movable regulator is achieved.
Gemäß einer weiteren Variante der vorliegenden Erfindung umfasst die Einstelleinrichtung einen drehbaren Regler, der in ergonomischer Hinsicht bevorzugt in einer Richtung quer zur Abgaberichtung des Spritzguts verstellbar ist.According to a further variant of the present invention, the adjusting device comprises a rotatable regulator, which is preferably adjustable in an ergonomic respect in a direction transverse to the dispensing direction of the injection molding.
Die Einstelleinrichtung kann derart ausgebildet sein, dass die Spritzgutmenge pro Zeiteinheit in zumindest zwei Stufen oder stufenlos einstellbar ist. Die stufenweise Einstellung erleichtert die Bedienung der Einstelleinrichtung für einen nicht fachkundigen Benutzer bzw. einen Benutzer, der die Spritzpistole nur selten verwendet. Eine stufenlose Einstellung ist hinsichtlich der Flexibilität der Spritzgutabgabe von Vorteil. Gemäß einer Ausgestaltung der vorliegenden Erfindung weist die Einstelleinrichtung ferner zumindest eine Markierung auf, die eine vordefinierte Grundstellung definiert, welche einer abzugebenden vorbestimmten Spritzgutmenge pro Zeiteinheit entspricht, wobei die Einstelleinrichtung derart ausgebildet ist, dass die Spritzgutmenge ausgehend von der Grundstellung wahlweise erhöht oder verringert werden kann. Eine solche Grundstellung ist dahingehend von Vorteil, dass sie für den Benutzer eine Orientierungshilfe bezüglich der aktuellen Einstellung der Einstelleinrichtung bietet .The adjusting device can be designed such that the amount of sprayed material per unit time is adjustable in at least two stages or continuously. The stepwise adjustment facilitates the operation of the adjustment device for a non-expert user or a user who rarely uses the spray gun. A stepless adjustment is advantageous in terms of the flexibility of the spray delivery. According to one embodiment of the present invention, the adjusting further comprises at least one mark defining a predefined basic position corresponding to a predetermined amount of spray material to be dispensed per unit time, wherein the adjusting device is designed such that the spray material can be increased or decreased starting from the basic position , Such a basic position is advantageous in that it provides the user with an orientation aid with regard to the current setting of the setting device.
Bevorzugt ist die Einstelleinrichtung ferner derart ausgebildet, dass beim Erreichen der Grundstellung ein Signal ausgegeben wird, bei dem es sich bevorzugt um ein akustisches Signal handelt. Ein solches akustisches Signal kann in Form eines Klick-Geräusches bereitgestellt werden, wie es von Schaltern bekannt ist, die in anderen technischen Anwendungsgebieten verwendet werden. Derartige Klick-Geräusche können beispielsweise erzeugt werden, indem eine leicht lösbare Rastverbindung zwischen einem Vorsprung und einer Aussparung beim Durchgang durch die Grundstellung miteinander in und aus dem Eingriff kommt.Preferably, the adjusting device is further designed such that upon reaching the home position, a signal is output, which is preferably an acoustic signal.

As shown with reference to FIG. 2, the operating switch 22 is held on the spray unit 14, but it is integrated into the handle 20 of the electric unit 12 as soon as the electric unit 12 is connected to the spray unit 14, as shown in FIG is shown.
Fig. 3 ist eine vergrößerte Ansicht des in Fig. 1 mit der Bezugsziffer III gekennzeichneten kreisförmigen Abschnitts und zeigt den Bedienschalter 22 mit der in diesen integrierten Einstelleinrichtung 24 gemäß einer ersten Variante der vorliegenden Erfindung. Die Einstelleinrichtung 24 umfasst einen drehbaren Regler 36 mit einem Rädchen, das in einer in dem Druckschalter 22 ausgebildeten durchgehenden Aussparung 38 aufgenommen ist und teilweise aus dieser seitlich von beiden Seiten des Bedienschalters 22 vorsteht, so dass es von einem den Handgriff haltenden Benutzer betätigt werden kann. Dieser drehbare Regler 36 befindet sich in der Ansicht gemäß Fig. 3 in einer vordefinierten Grundstellung, die einer abzugebenden vorbestimmten Spritzgutmenge pro Zeiteinheit entspricht. Diese Grundstellung ist vorliegend durch zwei Markierungen definiert, und zwar durch eine erste strichförmige Markierung 40, die neben dem drehbaren Regler 36 etwa auf halber Höhe desselben angeordnet ist, und eine zweite strichförmige Markierung 42, die am Außenumfang des drehbaren Reglers 36 vorgesehen ist. Der drehbare Regler 36 befindet sich dann in der vordefinierten Grundstellung, wenn die erste Markierung 40 mit der zweiten Markierung 42 fluchtet, wie es in Fig. 3 gezeigt ist. Ausgehend von dieser Grundstellung kann die Spritzgutmenge, die von der Spritzpistole 10 abgegeben werden soll, wahlweise erhöht werden, indem der drehbare Regler 36 in Abwärtsrichtung gedreht wird, oder verringert werden, indem der drehbare Regler 36 in Aufwärtsrichtung gedreht wird. Eine solche vordefinierte Grundstellung des drehbaren Reglers 36, die vorliegend durch die Markierungen 40 und 42 gekennzeichnet ist, ist dahingehend von Vorteil, dass ein Benutzer die aktuelle Einstellung des drehbaren Reglers 36 anhand dieser vordefinierten Grundstellung einschätzen kann. Um dem Benutzer anzuzeigen, in welcher Richtung der drehbare Regler 36 gedreht werden muss, um die von der Spritzpistole pro Zeiteinheit abzugebende Spritzgutmenge zu erhöhen oder zu verringern, sind an dem Bedienschalter 22 oberhalb und unterhalb des drehbaren Reglers 36 zwei weitere Markierungen 44 und 46 in Form eines Pluszeichens und eines Minuszeichens vorgesehen, wobei das Pluszeichen eine Erhöhung und das Minuszeichen eine Verringerung der Spritzgutmenge pro Zeiteinheit symbolisiert.Fig. 3 is an enlarged view of the circular portion indicated by the reference numeral III in Fig. 1, showing the operating switch 22 with the integrated adjusting means 24 according to a first variant of the present invention. The adjuster 24 includes a rotatable regulator 36 having a wheel received in and partially protruding from a continuous recess 38 formed in the pressure switch 22 from both sides of the control switch 22 so that it can be actuated by a user holding the handle , This rotatable controller 36 is located in the view of FIG. 3 in a predefined basic position, which corresponds to a dispensed predetermined amount of spray material per unit time. This basic position is defined here by two markings, namely by a first line-shaped marking 40, which is arranged approximately at half the height thereof next to the rotatable regulator 36, and a second line-shaped marking 42 which is provided on the outer circumference of the rotatable regulator 36. The rotatable controller 36 is then in the predefined basic position when the first mark 40 is aligned with the second mark 42, as shown in Fig. 3. From this initial position, the amount of sprayed material to be discharged from the spray gun 10 can be selectively increased by rotating the rotary regulator 36 in the downward direction, or decreased by rotating the rotary regulator 36 in the upward direction. Such a predefined basic position of the rotatable regulator 36, which is characterized in the present case by the markings 40 and 42, is advantageous in that a user can estimate the current setting of the rotatable regulator 36 on the basis of this predefined basic position. To indicate to the user in which direction the rotatable regulator 36 has to be rotated in order to increase or decrease the amount of spray to be dispensed by the spray gun per unit time, two further markings 44 and 46 are provided on the operating switch 22 above and below the rotatable regulator 36 Form of a plus sign and a minus sign provided, the plus sign symbolizes an increase and the minus sign a reduction in the amount of sprayed material per unit of time.
Der in Fig. 3 dargestellte drehbare Regler 36 kann als mehrstufiger oder als stufenloser Regler ausgebildet sein. Ferner ist der drehbare Regler 36 bevorzugt derart ausgebildet, dass bei Erreichen der Grundstellung, welche durch die Markierungen 40 und 42 definiert wird, ein Signal ausgegeben wird, wie beispielsweise ein akustisches Signal. Bei diesem akustischen Signal kann es sich um ein Klick-Signal handeln, das durch beim Durchgang durch die Grundstellung miteinander in und aus dem Eingriff kommende Rastelemente der Einstelleinrichtung 24 erzeugt wird. Ein solches Signal erleichtert die Handhabung der Einstelleinrichtung 24.The rotatable controller 36 shown in Fig. 3 may be formed as a multi-stage or as a continuous controller. Furthermore, the rotatable controller 36 is preferably designed such that upon reaching the home position, which is defined by the markings 40 and 42, a signal is output, such as an acoustic signal. This acoustic signal may be a click signal which is generated by locking elements of the adjusting device 24 coming into and out of engagement with one another when passing through the basic position. Such a signal facilitates handling of the adjustment device 24.
Fig. 4 ist eine Ansicht ähnlich Fig. 3, die eine alternative Ausgestaltung einer Einstelleinrichtung 24 gemäß der vorliegenden Erfindung zeigt. Gemäß Fig. 4 umfasst die Einstelleinrichtung 24 einen verschiebbaren Regler 48, der, ausgehend von einer durch die Markierungen 40 und 42 definierten Grundstellung, im Wesentlichen horizontal (in Abgaberichtung des Spritzguts) vor- und zu- rückbewegt werden kann, um die von der Spritzpistole 10 abzugebende Spritzgutmenge pro Zeiteinheit zu erhöhen oder zu verringern. Markierungen 44 und 46 in Form eines Pluszeichens und eines Minuszeichens geben die hierfür erforderlichen Bewegungsrichtungen an.Fig. 4 is a view similar to Fig. 3, showing an alternative embodiment of an adjuster 24 according to the present invention. 4, the adjusting device 24 comprises a displaceable regulator 48 which, starting from a basic position defined by the markings 40 and 42, extends substantially horizontally (in the discharge direction of the injection molding material) upstream and downstream. can be moved back to increase or reduce the amount of spray to be delivered by the spray gun 10 per unit time. Marks 44 and 46 in the form of a plus sign and a minus sign indicate the movement directions required for this purpose.
