Description

DEUTSCHESGERMAN

Bei gewissen Arten von Malen durch Spritzen, insbesondere in Fällen, in denen sehr dicke Farben verwendet werden, erfolgt die Farbzufuhr zu der Spritzpistole über einen Schlauch, der unmittelbar an eine elektromotorisch angetriebene Farbpumpe mit einem Füllbehälter angeschlossen ist, der an der Einlaßöffnung der Pumpe angebracht ist. Das Anlassen und Abstellen des Elektromotors erfolgt gewöhnlich mittels eines an der Spritzpistole angeordneten Schalters. Beim Spritzen wird zuerst der Motor angelassen und danach der Abzug der Spritzpistole eingedrückt. Wenn das Spritzen aufhören soll, werden diese Schritte in umgekehrter Reihenfolge ausgeführt. Dieses Verfahren hat jedoch mehrere Nachteile. Einerseits wird die Pistole durch das Gewicht des Schalters schwerer und dadurch die Arbeit für den Spritzer mühsamer, andererseits besteht immer die Gefahr elektrischer Überschläge zu der Spritzpistole, insbesondere weil die Farben, die mittels solcher Einrichtungen gespritzt werden, Wasser enthalten. Schließlich bedeutet das Anlassen und Abstellen des Motors einen zusätzlichen Arbeitsschritt, der eine gewisse Zeit erfordert. Nachdem der Motor angelassen und bevor er abgestellt worden ist, gibt es gewisse Augenblicke, während denen die Pumpe gegen eine vollkommen geschlossene Leitung arbeiten muß, wobei der Druck im Farbschlauch außerordentlich gesteigert wird. Gleichzeitig wird die Pumpenabnutzung wesentlich erhöht. Würde der Spritzer, was oft vorkommt, das Spritzen nur kurz unterbrechen wollen, vielleicht nur einige wenige Minuten, geschieht es oft, daß er es unterläßt, den Pumpenmotor abzustellen. Es entsteht dann ein besonders hoher Druck im Farbschlauch, der ja zu einem gewissen Grade elastisch ist. Wenn der Spritzer dann den Pistolenabzug eindrückt, um das Spritzen wieder zu beginnen, kommt im ersten Augenblick vielleicht eine doppelt so große Farbmenge als im nächsten Augenblick, wenn der Druck wieder nur von der Leistung der Pumpe bestimmt wird. Daß eine solche ungleichmäßige Farbzufuhr auf das Spritzresultat unvorteilhaft einwirkt, ist selbstverständlich.In certain types of painting by spraying, especially in cases where very thick paints are used are, the paint is supplied to the spray gun via a hose that is directly connected to a Electrically driven paint pump is connected to a filling container, which is at the inlet opening attached to the pump. The starting and stopping of the electric motor is usually done by means of a switch arranged on the spray gun. When spraying, the engine is started first and then the trigger of the spray gun depressed. If you want to stop spraying, these will Steps performed in reverse order. However, this method has several disadvantages. On the one hand the weight of the switch makes the gun heavier and thus the work for the sprayer more laborious, on the other hand there is always the risk of electrical flashovers to the spray gun, in particular because the paints that are sprayed by means of such devices contain water. In the end Starting and stopping the engine means an additional work step, which is a certain Takes time. After the engine has been started and before it has been switched off, there are certain moments during which the pump must work against a completely closed line, whereby the pressure in the paint hose is increased extraordinarily. At the same time, the pump wear becomes significant elevated. If the splash, which often happens, would only want to interrupt the spraying briefly, maybe only for a few minutes, it often happens that he fails to turn off the pump motor. It arises then a particularly high pressure in the paint hose, which is elastic to a certain extent is. Then when the splash pulls the gun trigger to start spraying again, it comes in the first moment perhaps twice as much color as in the next moment when the Pressure is again only determined by the performance of the pump. That such an uneven supply of paint has an unfavorable effect on the spraying result, of course.

Gemäß der Erfindung werden diese sämtlichen Nachteile dadurch beseitigt, daß der Abzug der Spritzpistole beim Eindrücken eine Druckerhöhung in einem an den Druckluftkanal der Spritzpistole angeschlossenen, nach einem Druckknopfschalter für die Bedienung der Farbzufuhr führenden Luftschlauch bewirkt.According to the invention, all of these disadvantages are eliminated in that the deduction of the Spray gun, when pushed in, increases the pressure in one connected to the compressed air channel of the spray gun, after a push-button switch for the operation of the paint supply leading air hose causes.

luft nach dem Luftkanalsystem 4 der Spritzpistole. air to the air duct system 4 of the spray gun.

Das Luftkanalsystem 4 ist durch einen Druckluftschlauch 5 an eine nicht gezeigte Druckluftquelle angeschlossen und durch einen Anschlußnippel 6 über einen Luftschlauch 7 an einen Druckknopfschalter 8 für einen Pumpenmotor 9 angeschlossen, der eine Farbpumpe 10 zur Förderung von Farbe von einem Füllbehälter 11 über einen Farbschlauch 12 zu einer Farbverteildüse 15 der Farbpistole 1 antreibt.The air duct system 4 is connected to a compressed air source (not shown) by a compressed air hose 5 and through a connection nipple 6 via an air hose 7 to a push-button switch 8 for a pump motor 9 connected to a paint pump 10 for delivering paint from a Filling container 11 drives via a paint hose 12 to a paint distribution nozzle 15 of paint gun 1.

Der Abzug 2 ist mit einer den Farbzufluß regelnden Farbnadel 13 gelenkig verbunden.The trigger 2 is connected in an articulated manner to a paint needle 13 which regulates the flow of paint.

Die Wirkungsweise der Vorrichtung ist folgende: Wenn der Pistolenabzug 2 eingedrückt wird, betätigt er außer der Farbnadel 13 auch das Luftventil 3. Die Druckluft für die Feinverteilung der Farbe strömt dann durch einen Luftkanal 14 im oberen Teil der Pistole 1 nach der Verteiler düse, und da der Schlauch 7 am Nippel 6 an diesen Luftkanal angeschlossen ist, wird auch Druckluft nach dem Druckknopfschalter 8 geführt, der den Pumpenmotor 9 anläßt, der die Farbpumpe 10 antreibt, die über den Farbschlauch 12 Farbe für die Spritzpistole 1 liefert. Wenn der Abzug freigegeben wird, werden sowohl die Farbzufuhr als auch das Luftventil 3 geschlossen. Der Luftkanal 14, an den der Luftschlauch 7 über den Nippel 6 angeschlossen ist, wird dann von Druckluft entleert, da dieser Luftkanal über die Verteilerdüse mit der freien Luft Verbindung hat. Wenn kein Druck mehr im Luftschlauch 7 herrscht, wird der Druckknopfschalter 8 ausgeschaltet (der Druckknopfschalter ist der-The mode of operation of the device is as follows: When the gun trigger 2 is depressed, actuated Besides the paint needle 13, he also has the air valve 3. The compressed air for the fine distribution of the paint flows then through an air duct 14 in the upper part of the gun 1 after the distributor nozzle, and there the hose 7 is connected to this air duct at the nipple 6, compressed air is also supplied after the push-button switch 8 out, which starts the pump motor 9, which drives the paint pump 10, which via the paint hose 12 Paint for the spray gun 1 supplies. When the print is released, both the ink supply and the the air valve 3 is also closed. The air duct 14 to which the air hose 7 is connected via the nipple 6 is then emptied by compressed air, as this air channel via the distributor nozzle with the free Has air connection. When there is no longer any pressure in the air hose 7, the push-button switch is activated 8 switched off (the push-button switch is
