"Elektrostatische Handsprit^pistole" (Ausscheidung aus P 15 77 «45.7-27)"Electrostatic handspray gun" (Elimination from P 15 77 «45.7-27)

Die Erfindung betrifft eine elektrostatische Handsprifczpiütole, bestehend aus einem sprühkopf, Vorratsbehälter und Handgriff, bei der der sprühkopf auf Hochspannungspotential liegt. The invention relates to an electrostatic handheld spray gun, consisting of a spray head, storage container and handle, in which the spray head is at high voltage potential.

Zi> sind bereits Handspritzpistolen in großer Zahl bekannt, öle besitzen, gleichgültig ob sie elektrostatisch oder mittels Druckluft betrieben werden, den erheblichen Nachteil, daß sie stets über Kabel oder Leitung mit ihrer Versorgungsquelle in Verbindung stehen müssen. Sie sind daher mehr oder weniger ortsgebunden.Zi> hand spray guns are already known in large numbers, Regardless of whether they are operated electrostatically or by means of compressed air, oils have the considerable disadvantage that they that they must always be connected to their source of supply via cable or wire. they are therefore more or less localized.

Der Erfindung liegt die Aufgabe zugrunde, eine nicht ortsgebundene Handspritzpistole verfügbar zu machen.The invention is based on the object of a non-stationary Make hand spray gun available.

Diese Aufgabe wird gemäß der Erfindung dadurch, gelöst, daß Teile der Hochspannungsquelle wie Sammler, Transformator und Wechselrichter in einer Tragtasche untergebracht sind.This object is achieved according to the invention in that Parts of the high voltage source such as collector, transformer and inverters are housed in a carrying bag.

Mit der elektrostatischen Handspritzpistole nach der Erfindung ist es möglich, unabhängig von einer ortsfesten Spannungsquelle, praktisch an jedem Ort Werkstücke auf elektrostatischem Wege mit einem Überzugsmaterial zu versehen.With the electrostatic manual spray gun according to the invention, it is possible, independently of a stationary voltage source, to provide workpieces with a coating material by electrostatic means at practically any location.

In der Figur ist ein Ausführungsbeispiel nach der Erfindung dargestellt.In the figure is an embodiment according to the invention shown.

Die Handspritzpistole besteht aus dem Sprühkopf1, dem Vorratsbehälter 2, einem isolierenden Werkstück der Hochspannungsquelle 3, einer Abschirmung 4 sowie dem Handgriff 5· Der Sprühkopf weist einen rechteckförmigen Querschnitt auf, dessen eine Längskante den Sprühspalt 6 enthält. Um die Sprühverluste so gering wie möglich zu halten, ist es zweckmäßig, den Sprühkopf aus einem isolierenden Kunststoff herzustellen. Zur Aufladung der Partikel des Überzugsmaterials befindet sich im Inneren des Sprühkopfes 1 eine Sprühelektrode 7» beispielsweise in Form eines Sprühdrahtes. Zur Erzielung kurzer Leitungsverbindungen Ist der Sprühdraht unmittelbar an das Anschlußelement der Hochspannungsquelle 3 angeschlossen. Die Sprühelektrode 7 ist vorzugsweise an den negativen Pol der Hochspannungsquelle 3 gelegt, während der positive Pol auf Erdpotential liegt.The hand spray gun consists of the spray head1, the storage container 2, an insulating workpiece of the high voltage source 3, a shield 4 and the handle 5 · The spray head has a rectangular cross-section, the one longitudinal edge contains the spray gap 6. In order to keep the spray losses as low as possible, it is advisable to use the spray head made of an insulating plastic. To charge the particles of the coating material is located in the Inside the spray head 1, a spray electrode 7 », for example in the form of a spray wire. To achieve short line connections, the spray wire is directly on the connection element the high voltage source 3 connected. The spray electrode 7 is preferably connected to the negative pole of the high voltage source 3 while the positive pole is at ground potential.

Aus der Hochspannungsquelle 3 sind der Sammler 8 und die Wechselrichter entfernt und in der Tragtasche 9 angeordnet. Die Verbindung des Hochspannungsteils in der Spritzpistole mit der Tragtasche kann über ein Kabel 10 erfolgen, das zweckmäßig für eine Spannung von 1 kV und ein.-; Frequenz von etwa 10 kHz bemessen ist. Unter Umständen ist es möglich, in die Tragtasche zugleich ein Ladegerät für den Sammler 8 vorzusehen.From the high voltage source 3, the collector 8 and the Inverter removed and arranged in the carrying bag 9. The connection of the high voltage part in the spray gun with the bag can be done via a cable 10, which is appropriate for a voltage of 1 kV and a.-; Frequency of about 10 kHz is dimensioned. Under certain circumstances it is possible to provide a charger for the collector 8 in the carrying bag at the same time.
