Description

Stand der TechnikState of the art

Die vorliegende Erfindung betrifft ein handgehaltenes Auftraggerät gemäß dem Oberbegriff vom Anspruch 1.The present invention relates to a hand-held applicator according to the preamble of claim 1.

Handgehaltene Auftraggeräte sind im Stand der Technik in unterschiedlichen Ausgestaltungen bekannt. Sie können zum Auftragen von flüssigen Materialien dienen, wie beispielsweise zum Auftragen einer Farbe, eines Lackes, einer Lasur, einer Grundierung, einer Beize, eines Holzschutzmittels oder dergleichen. Ebenso können sie zum Auftragen pastöser Medien ausgebildet sein, insbesondere zum Auftragen einer Spachtelmasse, einer Dichtungsmasse oder dergleichen.Hand-held applicators are known in the art in various configurations. They may be used to apply liquid materials such as paint, varnish, glaze, primer, stain, wood preservative or the like. Likewise, they can be designed for applying pasty media, in particular for applying a filler, a sealant or the like.

Beispielsweise ist auf Markt unter der Produktbezeichnung "Roller King" ein handgehaltenes Farbauftraggerät erhältlich, das ein Griffteil, ein daran gehaltenes Auftragteil in Form einer Farbwalze und ein mit dem Auftragteil fluidtechnisch verbindbares Farbreservoir umfasst. Das Farbreservoir ist direkt oberhalb der Farbwalze positioniert, so dass der Farbwalze die in dem Farbreservoir aufgenommene Farbe automatisch unter dem Einfluss der Schwerkraft zugeführt wird. Dieser Aufbau ist allerdings dahingehend von Nachteil, dass die Farbzufuhr beim Streichen über Kopf nicht gewährleistet werden kann. Darüber hinaus muss das Farbreservoir mit einem Trichter befüllt werden, was in der Praxis sehr umständlich ist.For example, on the market under the product name "Roller King" a hand-held inking device is available, which comprises a handle portion, a job held in the form of a paint roller and fluidly connected to the order part color reservoir. The ink reservoir is positioned directly above the inking roller so that the inking roller is automatically supplied with the ink received in the ink reservoir under the influence of gravity. However, this structure is disadvantageous to the extent that the ink supply when stroking over head can not be guaranteed. In addition, the ink reservoir must be filled with a funnel, which is very cumbersome in practice.

Bei einer weiteren bekannten Ausgestaltung, die von der Firma Wagner GmbH unter der Produktbezeichnung "Handi-Roller" angeboten wird, ist das Farbreservoir in das stielförmig ausgebildete Griffteil integriert, wobei die in dem Farbreservoir befindliche Farbe mit Hilfe eines über ein manuelles Pumpsystem betätigbares, auf den Aufnahmeraum des Farbreservoirs wirkendes Presselement zur Farbwalze gefördert werden kann. Ein Nachteil eines solchen Aufbaus besteht darin, dass der Druckspeicher des Pumpsystems ein großes Volumen einnimmt. Ferner ist die manuelle Betätigung des Pumpsystems sehr mühsam. Darüber hinaus variiert der Druck, weshalb keine gleichmäßige Farbabgabe an die Farbwalze gewährleistet werden kann.In a further known embodiment, which is offered by the company Wagner GmbH under the product name "Handi-Roller", the ink reservoir is integrated into the handle-shaped grip part, wherein the ink contained in the ink reservoir with the aid of a manual pumping system actuated on the receiving space of the ink reservoir acting pressing element can be promoted to the ink roller. A disadvantage of such a construction is that the pressure accumulator of the pumping system occupies a large volume. Furthermore, the manual operation of the pumping system is very tedious. In addition, the pressure varies, which is why no uniform ink delivery to the inking roller can be ensured.

Darüber hinaus sind so genannte Silikonspritzen bekannt, die ein Griffteil, ein an dem Griffteil lösbar aufgenommenes Reservoir in Form einer Silikonwechselkartusche, ein an dem Reservoir gehaltenes und als Düse ausgebildetes Auftragteil und ein von außen auf das Reservoir wirkendes Presselement umfassen, das manuell betätigbar ist und mit dem das in dem Reservoir enthaltene Material durch eine Reservoiröffnung in die Düse gedrückt werden kann. Ein Nachteil dieses Aufbaus besteht darin, dass die manuelle Betätigung des Presselementes sehr mühsam ist. Ferner ist viel Erfahrung mit dem Umgang der Silikonspritze erforderlich, um eine gleichmäßige Silikonabgabe zu realisieren. Darüber hinaus steht ein Pressstab, über den das Presselement bewegt wird, bei noch vollständig gefüllter Silikonwechselkartusche weit nach außen vor, was bei manchen Anwendungsfällen problematisch sein kann.In addition, so-called silicone syringes are known, which comprise a handle part, a releasably received on the handle reservoir in the form of a silicone change cartridge, a held on the reservoir and designed as a nozzle application part and an externally acting on the reservoir pressing member which is manually operable and with which the material contained in the reservoir can be pushed through a reservoir opening in the nozzle. A disadvantage of this structure is that the manual operation of the pressing element is very tedious. Furthermore, much experience with the handling of the silicone syringe is required to realize a uniform silicone release. In addition, a pressing rod, over which the pressing element is moved, is still far outward with the silicone exchange cartridge still completely filled, which can be problematic in some applications.

The US 2005/0238412 A1 relates to an electric toothbrush with integrated dispenser for supplying toothpaste.

Die WO 2009/088539 A1 offenbart ein Auftraggerät gemäß dem Oberbegriff vom Anspruch 1.The WO 2009/088539 A1 discloses an applicator according to the preamble of claim 1.

Ausgehend von diesem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, ein handgehaltenes Auftraggerät der eingangs genannten Art mit alternativem Aufbau zu schaffen, das flexibel und bequem handhabbar ist, das kleine Abmessungen aufweist und bei dem eine gleichmäßige Farbabgabe an das Auftragteil gewährleistet ist.Based on this prior art, it is an object of the present invention to provide a hand-held applicator of the type mentioned above with an alternative structure, which is flexible and easy to handle, which has small dimensions and in which a uniform color output is guaranteed to the application part.

Zur Lösung dieser Aufgabe schafft die vorliegende Erfindung ein handgehaltenes Auftraggerät der eingangs genannten Art, das dadurch gekennzeichnet ist, dass eine mit dem Motor drehbare Gewindespindel vorgesehen ist, die das Presselement wahlweise vor oder zurück bewegt, um das Material zum Auftragteil zu fördern oder das Reservoir mit neuem Material zu befüllen.To achieve this object, the present invention provides a hand-held applicator of the type mentioned, which is characterized in that a rotatable with the motor threaded spindle is provided which selectively moves the pressing element back or forth to promote the material to the application part or the reservoir to fill with new material.

Wird die Gewindespindel in die eine Richtung gedreht, so wird das in dem Reservoir befindliche Material durch die Reservoiröffnung zum Auftragteil gefördert. Das Fördervolumen kann dabei konstant gehalten oder bedarfsgerecht variiert werden, indem die Drehzahl der Gewindespindel entsprechend eingestellt wird. Wird die Gewindespindel bei zumindest teilweise entleertem Reservoir hingegen in die andere Richtung gedreht, so entsteht ein Unterdruck, unter dessen Wirkung sich das Reservoir mit neuem Material befüllen lässt, indem dieses beispielsweise über eine Schlauchleitung mit einem externen Materialreservoir verbunden wird. Da die Gewindespindel motorisch angetrieben wird, ist die Handhabung des erfindungsgemäßen Auftraggeräts sehr bequem und einfach. Darüber hinaus lässt sich der Volumenstrom des dem Auftragteil zuzuführenden Materials präzise einstellen.If the threaded spindle is rotated in one direction, the material in the reservoir is conveyed through the reservoir opening to the application part. The delivery volume can be kept constant or varied as needed by the speed of the threaded spindle is adjusted accordingly. If, however, the threaded spindle is rotated in the other direction when the reservoir is at least partially empty, a negative pressure is created under the action of which the reservoir can be filled with new material, for example by connecting it to an external material reservoir via a hose line. Since the threaded spindle is driven by a motor, the handling of the applicator device according to the invention is very convenient and simple. In addition, the volume flow of the material to be supplied to the application part can be precisely adjusted.

Gemäß einer Ausgestaltung der vorliegenden Erfindung sind die Gewindespindel und das Presselement in dem Aufnahmeraum des Reservoirs angeordnet, wobei das Presselement dichtend an der Wandung des Aufnahmeraums anliegt, und das Presselement ist im Gewindeangriff mit der Gewindespindel drehfest in Bezug auf den Aufnahmeraum angeordnet, so dass es bei Drehung der Gewindespindel in Abhängigkeit von ihrer Drehrichtung im Aufnahmeraum vor oder zurück bewegt wird. Die Anordnung der Gewindespindel innerhalb des Aufnahmeraums des Reservoirs ist dahingehend von Vorteil, dass nur sehr wenig Bauraum erforderlich ist.According to one embodiment of the present invention, the threaded spindle and the pressing member are arranged in the receiving space of the reservoir, wherein the pressing member sealingly abuts against the wall of the receiving space, and the pressing member is rotatably arranged in threaded engagement with the threaded spindle with respect to the receiving space, so that upon rotation of the threaded spindle, depending on its direction of rotation in the receiving space is moved back or forth. The arrangement of the threaded spindle within the receiving space of the reservoir is advantageous in that only very little space is required.

Die Gewindespindel ist bevorzugt an dem Reservoir gelagert, wodurch ein sehr kompakter und stabiler Aufbau erzielt wird.The threaded spindle is preferably mounted on the reservoir, whereby a very compact and stable construction is achieved.

Das Reservoir ist vorteilhaft lösbar an dem Auftraggerät gehalten, wodurch insbesondere Reparatur-, Austausch- und Reinigungsarbeiten vereinfacht werden.The reservoir is advantageously releasably held on the applicator, which in particular repair, replacement and cleaning operations are simplified.

Bevorzugt sind die Gewindespindel und der Motor über eine drehfeste Verbindung lösbar miteinander verbunden, wodurch die Montage und die Demontage des Reservoirs vereinfacht wird.Preferably, the threaded spindle and the motor via a rotationally fixed connection are detachably connected to each other, whereby the assembly and disassembly of the reservoir is simplified.

Gemäß einer Ausgestaltung der vorliegenden Erfindung ist das Reservoir fluidtechnisch wahlweise mit dem Auftragteil oder mit einem externen Farbreservoir verbindbar.According to one embodiment of the present invention, the reservoir is fluidly connectable either with the application part or with an external ink reservoir.

Insbesondere ist ein Ventil zum wahlweisen Öffnen einer der beiden Fluidverbindungen oder zum Sperren beider Fluidverbindungen vorgesehen, wodurch die Handhabung des Auftraggeräts stark vereinfacht wird.In particular, a valve for selectively opening one of the two fluid connections or for blocking both fluid connections is provided, whereby the handling of the applicator is greatly simplified.

Bevorzugt ist ein Betätigungsschalter vorgesehen, mit dem die Drehrichtung des Motors umkehrbar ist und/oder die Drehzahl des Motors regelbar ist und/oder das Ventil betätigbar ist.Preferably, an actuating switch is provided with which the direction of rotation of the motor is reversible and / or the speed of the motor is adjustable and / or the valve is actuated.

Das Auftraggerät kann mit einer autarken Energiequelle versehen sein und/oder einen Netzstecker zum Verbinden des Auftraggerätes mit einer externen Energiequelle aufweisen, um den Motor mit Strom zu versorgen.The applicator may be provided with a self-sufficient power source and / or may have a power plug for connecting the applicator to an external power source to power the motor.

Gemäß einer Ausgestaltung der vorliegenden Erfindung ist fluidtechnisch vor dem Auftragteil ein Verteiler vorgesehen, der das von dem Reservoir kommende Material dem Auftragteil zeitgleich an verschiedenen Stellen zuführt.According to one embodiment of the present invention, a distributor is provided in fluid technology in front of the application part, which supplies the material coming from the reservoir to the application part at different points at the same time.

Figur 1 zeigt ein handgehaltenes Auftraggerät 10 gemäß einer ersten Ausführungsform der vorliegenden Erfindung, das zum Auftragen von Farbe dient. Das Auftraggerät 10 umfasst ein Griffteil 12, ein am freien Ende des Griffteils 12 angeordnetes Gehäuse 14, ein an dem Gehäuse 14 drehbar gelagertes Auftragteil 16 in Form einer Farbwalze, ein in dem Gehäuse 14 aufgenommenes Reservoir 18, das fluidtechnisch mit dem Auftragteil 16 verbunden ist und einen Aufnahmeraum 20 zur Aufnahme der aufzutragenden Farbe definiert, und einen fluidtechnisch zwischen dem Auftragteil 16 und dem Reservoir 18 angeordneten Verteiler 22, der ebenfalls an dem Gehäuse 14 positioniert ist. FIG. 1 shows a hand-held applicator 10 according to a first embodiment of the present invention, which is for applying paint. The application device 10 comprises a grip part 12, a housing 14 arranged at the free end of the handle part 12, an application part 16 rotatably mounted on the housing 14 in the form of a paint roller, a reservoir 18 accommodated in the housing 14 and fluidly connected to the application part 16 and a receiving space 20 for receiving the paint to be applied, and a fluidly disposed between the applicator 16 and the reservoir 18 manifold 22, which is also positioned on the housing 14.

Das Reservoir 16, das lösbar in dem Gehäuse 14 aufgenommen ist, umfasst ein im Wesentlichen hohlzylindrisches Reservoirgehäuse 24, das den Aufnahmeraum 20 definiert. Durch das Reservoirgehäuse 24 erstreckt sich mittig eine Gewindespindel 26, die an dem Reservoirgehäuse 26 mittels einer Spindellagerung 28 drehbar gelagert ist. In dem Reservoirgehäuse 26 ist ein auf den Aufnahmeraum 20 wirkendes Presselement 30 aufgenommen, das im Gewindeeingriff mit der Gewindespindel 26 drehfest in Bezug auf das Reservoirgehäuse 24 angeordnet ist, so dass es bei Drehung der Gewindespindel 26 in Abhängigkeit von ihrer Drehrichtung im Aufnahmeraum 20 in Richtung der Pfeile 32, 34 vor oder zurückbewegt wird. Die Drehung der Gewindespindel 26 wird über einen Motor 36 realisiert, der innerhalb des Gehäuses 14 angeordnet ist. Eine in das Innere des Gehäuses 14 weisende Reservoiröffnung 38 ist fluidtechnisch mit einer Leitung 40 verbunden, die sich in eine Zuführleitung 42 und in eine Nachfüllleitung 44 verzweigt. Die Zuführleitung 42 ist fluid-technisch mit dem Verteiler 22 verbunden. Die Nachfülleitung 44 mündet in einem von dem Gehäuse 14 auswärts vorstehenden Nachfüllstutzen 46, an den zum Nachfüllen des Reservoirs 18 eine Schlauchleitung angeschlossen werden kann, wie es nachfolgend noch näher erläutert wird. Als Verzweigungspunkt der Leitungen 40, 42 und 44 ist ein Ventil 48 angeordnet, das wahlweise die Zuführleitung 42 oder die Nachfüllleitung 44 sperrt. In gesperrtem Zustand der Zuführleitung 42 kann Farbe entsprechend von der Nachfüllleitung 44 über die Leitung 40 in das Reservoir 18 strömen und umgekehrt. Sperrt das Ventil 48 hingegen die Nachfüllleitung 44, so kann Farbe aus dem Reservoir 18 über die Leitung 40 und die Zuführleitung 42 in den Verteiler 22 strömen.The reservoir 16, which is removably received in the housing 14, includes a substantially hollow cylindrical reservoir housing 24 defining the receiving space 20. Through the reservoir housing 24 extends centrally a threaded spindle 26 which is rotatably mounted on the reservoir housing 26 by means of a spindle bearing 28. In the reservoir housing 26, a force acting on the receiving space 20 pressing member 30 is received, the rotationally fixed in threaded engagement with the threaded spindle 26 with respect to the Reservoir housing 24 is arranged so that it is on rotation of the threaded spindle 26 in response to its direction of rotation in the receiving space 20 in the direction of arrows 32, 34 is moved forward or back. The rotation of the threaded spindle 26 is realized via a motor 36 which is arranged within the housing 14. A reservoir opening 38 pointing into the interior of the housing 14 is fluidly connected to a line 40 which branches into a supply line 42 and into a refill line 44. The supply line 42 is fluid-technically connected to the manifold 22. The refill line 44 discharges into a refilling nozzle 46 projecting outward from the housing 14, to which a hose line can be connected for refilling the reservoir 18, as will be explained in more detail below. As a branch point of the lines 40, 42 and 44, a valve 48 is arranged, which selectively blocks the supply line 42 or the refill 44. In the locked state of the supply line 42, ink can accordingly flow from the refill line 44 via the line 40 into the reservoir 18 and vice versa. On the other hand, if the valve 48 blocks the refill line 44, paint can flow from the reservoir 18 via the line 40 and the supply line 42 into the distributor 22.

Die Zuführleitung 42 mündet in einen Verteilerraum 50 einer Farbverteilerleiste 52 des Verteilers 22. Die Farbverteilerleiste 52 weist an ihrer dem Auftragteil 16 zugewandten Seite eine Reihe von Verteileröffnungen 54 auf, die in den Verteilerraum 50 eingeleitete Farbe gleichmäßig über die gesamte Länge des Auftragteils 16 an dem Außenumfang des Auftragteils 16 abgeben. Zum Ein- und Ausschalten des Auftraggerätes 10 ist am Griffteil 12 ein Druckschalter 56 vorgesehen. Zum Ansteuern des Motors 36 ist ebenfalls am Griffteil 12 ein Schiebeschalter 58 positioniert. Über den Schiebeschalter 58 lassen sich sowohl die Drehrichtung als auch die Drehzahl des Motors 36 einstellen.The feed line 42 opens into a distributor chamber 50 of a paint distributor strip 52 of the distributor 22. The color distributor strip 52 has, on its side facing the application part 16, a series of distributor openings 54, the paint introduced into the distributor chamber 50 uniformly over the entire length of the application member 16 on the Output outer circumference of the order part 16. To turn on and off the applicator 10, a pressure switch 56 is provided on the handle part 12. For driving the motor 36, a slide switch 58 is also positioned on the handle part 12. Both the direction of rotation and the speed of the motor 36 can be adjusted via the slide switch 58.

Zur Durchführung von Malerarbeiten wird bei mit Farbe gefülltem Reservoir 18 das Auftraggerät 10 in einem ersten Schritt durch Drücken des Druckschalters 56 eingeschaltet. Daraufhin wird die Nachfüllleitung 44 mithilfe des Ventils 48 gesperrt. Wird nun der Schiebeschalter 58 vorwärts in Richtung des Gehäuses 14 bewegt, so wird der Motor 36 in derjenigen Drehrichtung angetrieben, in der das Presselement 30 aus der in Figur 1 dargestellten Stellung in Richtung des Pfeils 32 bewegt wird. Durch die Bewegung des Presselementes 30 wird innerhalb des Aufnahmeraums 20 ein Druck aufgebaut, so dass die in den Reservoir 18 enthaltene Farbe durch die Reservoiröffnung 38 in die Leitung 40 und von dort aus durch die Zuführleitung 42 in den Verteilerraum 50 der Farbverteilerleiste 52 strömt. Die Farbe verlässt den Verteilerraum 50 durch die Verteileröffnungen 54, wobei die Farbe gleichmäßig über die gesamte Länge des Auftragteils 16 an dessen Außenumfang abgegeben wird. Die durch die Federelemente XY erzeugte Vorspannung wird die Farbverteilerleiste 52 dabei gleichmäßig an das Auftragteil 16 angedrückt. Die an das Auftragteil 16 abgegebene Farbe kann nunmehr durch Abrollen des Auftragteils 16 auf einer Fläche eines zu streichenden Objekts an das Objekt abgegeben werden.To carry out painting work, when the reservoir 18 is filled with ink, the applicator 10 is switched on in a first step by pressing the pressure switch 56. Thereafter, the refill line 44 is disabled by means of the valve 48. Now, if the slide switch 58 is moved forward in the direction of the housing 14, the motor 36 is driven in the direction of rotation in which the pressing member 30 from the in FIG. 1 shown position in the direction of the arrow 32 is moved. As a result of the movement of the pressing element 30, a pressure is built up within the receiving space 20, so that the ink contained in the reservoir 18 flows through the reservoir opening 38 into the line 40 and from there through the feed line 42 into the distributor space 50 of the color distributor strip 52. The paint leaves the distributor space 50 through the distributor openings 54, the paint being dispensed uniformly over the entire length of the applicator 16 on its outer periphery. The bias generated by the spring elements XY the paint distribution strip 52 is pressed evenly to the application part 16. The output to the application part 16 color can now by unrolling the applicator 16 on a surface of an object to be painted are delivered to the object.

Zum Nachfüllen des Reservoirs 18 mit frischer Farbe wird ein freies Ende eines nicht näher dargestellten Schlauches an den auswärts von dem Gehäuse 14 des Auftraggerätes 10 vorstehenden Nachfüllstutzen 46 angeschlossen. Das andere freie Ende des Schlauches wird in ein externes Farbreservoir getunkt, wie beispielsweise in einen Farbeimer. Daraufhin wird unter Betätigung des Ventils 48 die Zuführleitung 42 gesperrt und die Nachfüllleitung 44 freigegeben. Wird nunmehr der Schiebeschalter 58 vom Gehäuse 14 wegbewegt, so wird der Motor 36 derart angetrieben, dass sich das Presselement 30 innerhalb des Aufnahmeraums 20 des Reservoirs 18 in Richtung des Pfeils 34 bewegt. Durch den hierbei entstehenden Unterdruck wird Farbe aus dem externen Farbreservoir durch den Schlauch, die Nachfüllleitung 44 und die Leitung 40 in das Reservoir 18 gesaugt, bis das Presselement 30 die in Figur 1 dargestellte Ausgangsstellung erreicht hat. Das Reservoir 18 ist nunmehr gefüllt. In einem weiteren Schritt wird der Schlauch von dem Nachfüllstutzen 46 abgezogen und die Nachfüllleitung 44 unter Betätigung des Ventils 48 gesperrt. Anschließend können die Streicharbeiten in der zuvor beschriebenen Art und Weise fortgesetzt werden.To refill the reservoir 18 with fresh paint, a free end of a hose not shown is connected to the outwardly of the housing 14 of the applicator 10 projecting refill 46. The other free end of the tube is dipped in an external color reservoir, such as a paint bucket. Then, the supply line 42 is blocked and the refill line 44 released by actuation of the valve 48. Now, the slide switch 58 is moved away from the housing 14, the motor 36 is driven so that the pressing member 30 moves within the receiving space 20 of the reservoir 18 in the direction of the arrow 34. As a result of the resulting negative pressure, ink is drawn from the external ink reservoir through the hose, the refill line 44 and the line 40 into the reservoir 18 until the pressing element 30 reaches the position indicated in FIG FIG. 1 has reached the initial position shown. The reservoir 18 is now filled. In a further step, the hose is withdrawn from the refill nozzle 46 and the refill line 44 is blocked by actuation of the valve 48. Subsequently, the coating work can be continued in the manner described above.
