Abstract

The rotary atomizer has a spray element detachably mounted on a rotating shaft (4). For locking of the shaft, a locking bolt (14) movable between two positions is mounted in the atomizer. In one of its positions the locking bolt engages with a locking hole (12) formed in or on the shaft to prevent its rotation in the shaft bearing unit (1), and in its other position allows the shaft to rotate. The locking bolt is movable from the released position into the locked position against the force of a return spring (20).

Description

Die Erfindung betrifft einen Rotationszerstäuber für eine Beschichtungsvorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a rotary atomizer for a coating device according to the preamble of claim 1.

Das aus einem Glockenteller bestehende Absprühelement bekannter Rotationszerstäuber ist in das freie offene Ende einer von einer Luftturbine angetriebenen Hohlwelle geschraubt, deren Lagereinheit mit der Turbine innerhalb der äußeren Gehäuseabdeckung des Zerstäubers eine modulare Baueinheit bildet (DE 4306800 A). Diese Baueinheit ist nach Abnehmen der Gehäuseabdeckung.zugänglich und mit der Hohlwelle und dem Glockenteller von den anderen Bestandteilen des Zerstäubers lösbar.The spraying element consisting of a bell plate is more well known Rotary atomizer is one of one in the free open end Screwed air turbine driven hollow shaft, its bearing unit with the turbine inside the outer casing cover of the Atomizer forms a modular unit (DE 4306800 A). This The unit is accessible after removing the housing cover and with the hollow shaft and the bell cup from the other components of the atomizer detachable.

Der Glockenteller muß bekanntlich von Zeit zu Zeit gewechselt oder gereinigt oder aus sonstigen Gründen aus der Hohlwelle herausgeschraubt werden. Zur Ermöglichung dieser Relativdrehung mußte die Hohlwelle bisher mit einem von außen angesetzten Gabelschlüssel oder sonstigen Werkzeug festgehalten werden. Die Bereitstellung und Handhabung dieses externen Werkzeugs ist nicht nur umständlich, mühsam und zeitraubend, sondern es besteht auch die Gefahr einer Beschädigung benachbarter Teile wie Lenkluftring und Gehäuse und des Glockentellers selbst sowie der Wellenlagerung durch die punktuelle Hebelbelastung mit dem Gabelschlüssel. Bei manchen Zerstäubern müssen außerdem zunächst weitere Teile abgebaut werden, damit das Werkzeug an der vorgesehenen Stelle der Welle angesetzt werden kann, wobei es zu Verschmutzungen der freigelegten Bereiche kommen kann.As is well known, the bell plate has to be changed from time to time or cleaned or unscrewed from the hollow shaft for other reasons become. To enable this relative rotation previously had to use the hollow shaft with an external wrench or other tools. The Provision and handling of this external tool is not only cumbersome, tedious and time consuming, but it exists also the risk of damage to neighboring parts such as Steering air ring and housing and the bell cup itself and the Shaft bearings through the selective lever loading with the open-ended wrench. With some atomizers you also need to start other parts are removed so that the tool on the intended Place of the shaft can be attached, causing contamination the exposed areas can come.

Aufgabe der Erfindung ist die Schaffung eines Rotationszerstäubers, dessen Absprühelement ohne die genannten Gefahren schneller und einfacher als bisher an der drehbar gelagerten Welle montiert und abmontiert werden kann. The object of the invention is to create a rotary atomizer, its spray element faster without the dangers mentioned and easier than before on the rotatably mounted shaft can be assembled and disassembled.

Diese Aufgabe wird durch die Merkmale der Patentansprüche gelöst.This object is solved by the features of the claims.

Durch die Erfindung wird ein externes Werkzeug überflüssig. Statt dessen kann die Welle auf einfachste Weise durch Betätigen des Arretiergliedes z.B. mit einem Finger einer Hand in ihrer Lagereinheit blockiert werden, wenn beispielsweise mit der anderen Hand der Glockenteller heraus- oder eingeschraubt werden soll. Die Betätigung des Arretiergliedes ist durch eine ggf. verschließbare Öffnung oder über Zwischenbetätigungsglieder auch von außerhalb des Zerstäubers her möglich. Insbesondere kann die Betätigung des Arretiergliedes auch automatisch erfolgen, beispielsweise pneumatisch mit Hilfe eines angesteuerten Ventils oder durch einen sonstigen Antrieb.The invention eliminates the need for an external tool. Instead, the shaft can be actuated in the simplest way of the locking member e.g. with a finger of a hand in hers Storage unit can be blocked, for example, with the other Hand of the bell plate can be screwed out or screwed in should. The actuation of the locking member is through an optionally closable opening or via intermediate actuators also possible from outside the atomizer. In particular can also operate the locking member automatically take place, for example pneumatically with the help of a controlled Valve or by another drive.

Die Arretierung kann zweckmäßig im Bereich des Axiallagers der Welle erfolgen. Durch die Arretierung ohne Werkzeug entfällt die Gefahr von Beschädigungen im Bereich des Glockentellers und des Lenkluftrings, des Zerstäubers sowie der Wellenlagerung. Außerdem werden neue konstruktive Möglichkeiten für die Anordnung des Glockentellers auf der Welle sowie für Modifikationen am Lenkluftring eröffnet.The lock can be useful in the area of the thrust bearing Wave. By locking without tools, the Risk of damage in the area of the bell plate and the Steering air rings, the atomizer and the shaft bearing. Moreover are new constructive possibilities for the arrangement of the bell plate on the shaft and for modifications on Steering air ring opened.

In Fig. 1 A ist eine Lagereinheit 1 eines Rotationszerstäubers dargestellt, die in der an sich bekannten und üblichen Weise mit dem im Bereich 2 befindlichen Luftturbinenmotor eine modulare Baueinheit bildet. In der Lagereinheit 1 rotiert luftgelagert die ebenfalls an sich übliche Hohlwelle 4, die an dem in Fig. 1 rechten Ende von einer Abdeckplatte 6 der Lagereinheit 1 eingeschlossen ist, während sie auf der entgegengesetzten Seite mit ihrem freien Ende 8 aus der Lagereinheit herausragt. Durch die Abdeckplatte 6 hindurch wird die Lager- und Turbineneinheit mit der erforderlichen Druckluft versorgt (Öffnungen hierfür sind in Fig. 2 zu sehen). Zum Einschrauben des (nicht dargestellten) Glockentellers hat die Hohlwelle 4 in ihrem freistehenden Ende 8 an der mit 9 bezeichneten Stelle ein Innengewinde. Bei 10 befindet sich die Stelle, wo bei bekannten Zerstäubern ein Werkzeug zum Festhalten der Welle angesetzt werden kann. Für Sonderfälle kann es zweckmäßig sein, diese Möglichkeit auch bei dem hier beschriebenen Zerstäuber beizubehalten.In Fig. 1 A is a storage unit 1 of a rotary atomizer shown in the known and usual manner with a modular turbine engine located in area 2 Unit forms. Air bearing rotates in the bearing unit 1 the hollow shaft 4, which is also conventional per se, which is connected to the shaft shown in right end enclosed by a cover plate 6 of the storage unit 1 is while using on the opposite side its free end 8 protrudes from the storage unit. Through the Cover plate 6 is the bearing and turbine unit with the required compressed air (openings for this are in Fig. 2 can be seen). For screwing in the (not shown) Bell plates have the hollow shaft 4 in its free-standing end 8 an internal thread at the point labeled 9. Located at 10 the place where a tool with known atomizers can be used to hold the shaft. For special cases it may be useful to do this with the one described here Maintain atomizer.

An ihrem in der Abdeckplatte 6 befindlichen Ende hat die Hohlwelle 4 in ihrer zylindrischen Wand die in Fig. 2 als Beispiel dargestellten vier Löcher 12, die in einer gemeinsamen radialen Ebene (der Schnittebene der Fig. 2) gleichmäßig um den Wellenumfang verteilt sind.At its end in the cover plate 6 has the hollow shaft 4 in its cylindrical wall that in Fig. 2 as an example shown four holes 12 in a common radial Plane (the section plane of Fig. 2) evenly around the shaft circumference are distributed.

Zum Eingriff in eines der Löcher 12 ist in der Abdeckplatte 6 ein mit seiner Achse linear radial in der genannten Ebene, also senkrecht zur Wellenachse verschiebbarer Arretierbolzen 14 der dargestellten abgestuften z. B. zylindrischen Form gelagert. Der abgestufte Bolzen 14 hat ein dünneres Endteil 15, mit dem er in die Löcher 12 paßt, und ein dickeres Schaftteil 16, mit dem er in einer entsprechend bemessenen, die Abdeckplatte 6 quer zu der Wellenachse bis zum Wellenumfang durchsetzenden Radialbohrung 18 gleitend geführt ist. Die Radialbohrung 18 ist darstellungsgemäß so abgestuft, daß sie an der Welle 4 den dem Endteil 15 entsprechenden geringeren Durchmesser hat und angrenzend an diese Abstufung mit dem Endteil 15 einen Ringspalt bildet, in dem eine spiralförmige Druckfeder 20 sitzt. Diese Druckfeder drückt gegen die Abstufungen der Bohrung 18 und des Bolzens 14 und hält ihn dadurch normalerweise in seiner Freigabestellung gemäß Fig. 1 A außerhalb der Welle 4. Gegen die Kraft der Feder 20 kann der Bolzen 14 beispielsweise durch Fingerdruck auf seinen Betätigungskopf 17 in seine Blockierstellung gemäß Fig. 1 B gedrückt werden. Eine in dem Bolzen 14 sitzende, in einem Begrenzungsspalt 22 in der Abdeckplatte 6 verschiebbare Schraube 23 verhindert ein Herausfallen des Bolzens 14 aus der Bohrung 18 und kann andererseits dessen Bewegung in Richtung zu der Hohlwelle 4 begrenzen.To engage in one of the holes 12, the cover plate 6 one with its axis linearly radial in the named plane, that is Locking bolt 14 which is displaceable perpendicular to the shaft axis illustrated graded z. B. stored cylindrical shape. The stepped bolt 14 has a thinner end portion 15, with which it in the holes 12 fits, and a thicker shaft portion 16 with which it in a correspondingly dimensioned, the cover plate 6 transverse to the Radial bore 18 penetrating the shaft axis up to the shaft circumference is slidably guided. The radial bore 18 is as shown graded so that they correspond to the end part 15 on the shaft 4 has a smaller diameter and is adjacent to this gradation with the end part 15 forms an annular gap in which a spiral compression spring 20 is seated. This compression spring presses against the gradations of the bore 18 and the bolt 14 and holds it thereby normally in its release position according to FIG. 1A outside the shaft 4. Against the force of the spring 20, the Bolt 14, for example, by finger pressure on its actuating head 17 pressed into its blocking position according to FIG. 1B become. One sitting in the bolt 14, in a limiting gap 22 prevents slidable screw 23 in the cover plate 6 falling out of the bolt 14 from the bore 18 and on the other hand limit its movement towards the hollow shaft 4.
