Abstract

A high rotation atomizer (1) functioning with inner charging comprises, in a known manner, a high-voltage circuit (3) which generates a high voltage that can be applied to a bell cup (6), from a low voltage. In a known manner, this high-voltage circuit (3) comprises a measuring resistor (14) in a circuit path between the turbine casing (7) of the turbine driving the bell cup (6) and ground. A first measuring voltage can be tapped at this first measuring resistor (14), which voltage is a measure for the voltage applied at the turbine casing (7). According to the invention, a second measuring resistor (10) is placed in a circuit path between the turbine casing (7) and ground. A second measuring voltage is tapped at this resistor, which is likewise a measure for the voltage applied at the turbine casing (7). If the information gained from the two measuring voltages deviates too strongly from each other, then the control device (13) triggers an error signal. By this means, the safety of the entire system is increased.

Description

Mit Innenaufladung arbeitender Hochrotationszerstäuber  With internal charging working high rotation atomizer
Die Erfindung betrifft einen mit Innenaufladung arbeitenden Hochrotationszerstäuber mit a) einem Außengehäuse; b) einem drehbar gelagerten Glockenteller; einer in einem Turbinengehäuse angeordneten Turbine, welche den Glockenteller in Drehung versetzt; einer Hochspannungschaltung, welcher eine niedrige The invention relates to a working with internal high-speed rotary atomizer with a) an outer casing; b) a rotatably mounted bell plate; a turbine housing disposed in a turbine housing, which sets the bell cup in rotation; a high voltage circuit, which has a low
Spannung zuführbar ist und die an einem Ausgang,  Voltage is supplied and at an output,
der mit dem Glockenteller, der Turbine und dem Turbinengehäuse elektrisch verbunden ist, eine Hochspannung erzeugt und umfasst : da) eine Hochspannungskaskade; einen Messwiderstand, der in einem zwischen dem Turbinengehäuse und Masse liegenden Strompfad liegt und an dem eine erste Messspannung abgreifbar ist, die ein Maß für die am Turbinen gehäuse liegende Spannung ist. Praktisch alle auf dem Markt befindlichen, derzeit bekannten Hochrotationszerstäuber, die mit Innenau'fladung arbeiten, besitzen diese Bauweise, so däss ein druckschriftlicher Nachweis entbehrlich ist. HochrotationsZerstäuber weisen aufgrund der in ihnen vorliegenden Hochspannung ein gewisses Gefahrenpotential auf und müssen daher sorgfältig überwacht werden. Eine Gefahr kann beispielsweise darin bestehen, dass sich das Turbinengehäuse, welches im Betrieb auf der hohen Spannung liegt, nach dem Abschalten der Hochspannungsschaltung nicht rasch und/ oder vollständig genug entlädt, sodass noch eine potentiell gefährliche Hochspannung an ihm verbleibt . which is electrically connected to the bell cup, the turbine and the turbine housing, generates a high voltage and comprises: da) a high voltage cascade; a measuring resistor which is located in a current path lying between the turbine housing and ground and to which a first measuring voltage can be tapped, which is a measure of the turbine housing lying voltage. Practically all on the market, currently known Hochrotationszerstäuber that work with Innenau'fladung own this construction, so that a printed documentary proof is unnecessary. High-rotation atomizers have a certain potential danger due to the high voltage present in them and must therefore be carefully monitored. For example, a hazard may be that the turbine housing, which is at high voltage during operation, does not discharge rapidly and / or completely enough after the high voltage circuit is turned off, leaving a potentially dangerous high voltage on it.
Aus diesem Grunde besitzen die bekannten Hochrotations- zerstäuber der eingangs genannten Art in ihrer Hochspan- nungsschaltung den oben genannten Messwiderstand. Im For this reason, the known high-speed rotary atomizers of the type mentioned in their high-voltage circuit have the above-mentioned measuring resistor. in the
Betrieb, also bei eingeschalteter Hochspannungsschaltung, wird die an ihm abfallende erste Messspannung zur Regelung der Hochspannung genutzt. Nach dem Abschalten der Hochspannungsschaltung dient die erste Messpannung zur Feststellung der Rest-Hochspannung, die noch am Turbinengehäuse liegt, also als Sicherheitsmassnahme .  Operation, ie with the high-voltage circuit switched on, the first measuring voltage dropping across it is used to control the high voltage. After switching off the high voltage circuit, the first measuring voltage is used to determine the residual high voltage, which is still on the turbine housing, so as a security measure.
Diese Sicherheitsmassnahme ist zwar im Allgemeinen hoch wirksam; generell besteht jedoch das Bedürfnis, das This safety measure is generally highly effective; Generally, however, there is a need, the
Risikopotential, das von einem Hochrotationszerstäuber ausgeht, weiter zu reduzieren. Risk potential, which emanates from a high-rotation atomizer, further reduce.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass e) ein weiterer Messwiderstand vorgesehen ist, der This object is achieved in that e) another measuring resistor is provided, the
ebenfalls in einem vom Turbinengehäuse zur Masse führenden Strompfad liegt und an dem eine zweite Mess- spannung abgreifbar ist, welche ein Maß für  is also located in a current path leading from the turbine housing to the ground and on which a second measuring voltage can be tapped, which is a measure of
die am Turbinengehäuse liegenden Spannung ist; f) eine Steuereinrichtung vorgesehen ist, welcher die  the voltage lying on the turbine housing is; f) a control device is provided, which the
beiden Messspannungen zuführbar sind und die bei  Both measuring voltages are supplied and the at
Überschreiten eines Maximalwerts der Differenz dieser MessSpannungen ein Störsignal abgibt . Erfindungsgemäß wird also eine redundante Überwachung der am Turbinengehäuse und an allen mit diesem elektrisch verbundenen, elektrisch leitenden Bauteilen liegenden Spannung geschaffen, die unabhängig von der bereits vorhandenen HochspannungsSchaltung ist. Wird in diesem zweiten Messkanal eine zu hohe Abweichung von der im ersten Messkanal gewonnenen Information über die Exceeding a maximum value of the difference of these measuring voltages emits an interference signal. Thus, according to the invention, a redundant monitoring of the voltage applied to the turbine housing and to all the electrically conductive components electrically connected thereto is created, which is independent of the already existing high-voltage circuit. Is in this second measuring channel too high a deviation from the information obtained in the first measuring channel on the
Spannung am Turbinengehäuse festgestellt, wird sofort ein Störsignal abgegeben. Durch diese redundante Maßnahme lässt sich die Sicherheit des Bedienungspersonales und der gesamten Anlage erheblich erhöhen. Voltage detected on the turbine housing, an interference signal is emitted immediately. This redundant measure can significantly increase the safety of the operating personnel and the entire system.
Durch das Störsignal der Steuereinrichtung ist vorzugsweise ein optisches oder akustisches Fehlersig- nal auslösbar. Hierdurch wird das Bedienungspersonal unverzüglich auf das Vorliegen einer Gefahr aufmerksam gemacht, so dass dieses sich aus dem Gefahrenbereich entfernen und/oder andere geeignet Massnahmen ergreifen kann. By the interference signal of the control device preferably an optical or acoustic Fehlerig- signal is triggered. As a result, the operator is immediately alerted to the presence of a hazard so that it can move away from the danger area and / or take other suitable measures.
Zweckmäßig ist ferner, wenn durch das Störsignal der Steuereinrichtung die Spannungszufuhr zur Hochspannungsschaltung abschaltbar ist. Diese Maßnahme reduziert die von einem fehlerhaften Hochrotationszer- stäuber ausgehende Gefahr erheblich. It is also expedient if the voltage supply to the high-voltage circuit can be switched off by the interference signal of the control device. This measure considerably reduces the danger emanating from a faulty high-speed rotary atomizer.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert; die ein- zige Figur zeigt schematisch im Schnitt den Kopfbereich eines Hochrotationszerstäubers. An embodiment of the invention will be explained in more detail with reference to the drawing; the single figure shows schematically in section the head area of a high rotation atomizer.
Der insgesamt mit dem Bezugszeichen 1 gekennzeichnete Hochrotationszerstäuber besitzt ein Außengehäuse 2, in dem die nachfolgend beschriebenen Elemente untergebracht sind: The Hochrotationszerstäuber designated overall by the reference numeral 1 has an outer housing 2, in which the elements described below are housed:
Mit dem Bezugszeichen 3 ist eine Hochspannungschaltung bezeichnet, wie sie grundsätzlich aus dem Stande der Technik bekannt ist. Diese erzeugt mit Hilfe einer schematisch dargestellten Hochspannungskaskade 15 aus einer niedrigen, mittelfrequenten WechselSpannung , beispielsweise 24 bis 36 V und 35 kHz, die ihr über die Leitung 4 zugeführt wird, eine Hochspannung, wie sie zum Betrieb eines Hochrotationszerstäubers erforderlich ist. Diese wird über eine Leitung 5 an einen Glockenteller 6 gelegt. Der Glockenteller 6 wird in bekannter Weise von einer Turbine in Drehung versetzt, die in einem in der Zeichnung erkennbaren Turbinengehäuse 7 gelagert ist . Bei mit Innenaufladung arbeitenden Hochrotationszerstäubern liegt dieselbe Hochspannung im Betrieb an der Turbine und am Turbinengehäuse 7. The reference numeral 3 designates a high voltage circuit, as it is known in principle from the prior art. This generates by means of a high-voltage cascade 15 shown schematically from a low, medium-frequency AC voltage, for example 24 to 36 V and 35 kHz, which is supplied via the line 4, a high voltage, as required for the operation of a high-rotation atomizer. This is placed via a line 5 to a bell plate 6. The bell cup 6 is rotated in a known manner by a turbine, which is mounted in a recognizable in the drawing turbine housing 7. When working with internal high-speed rotary atomizers the same high voltage is in operation at the turbine and the turbine housing. 7
Nicht dargestellt sind die pneumatischen Leitungen, die zum Betrieb der Turbine erforderlich sind, sowie die Leitung, über welche die zu versprühende Farbe dem Glockenteller 6 zugespeist wird. Diese Leitungen sind dem Fachmann bekannt . Die Hochspannungschaltung 3 enthält, wie dies ebenfalls dem Stande der Technik entspricht, einen Messwiderstand 14. Dieser ist in der Zeichnung nur schematisch angedeutet. Not shown are the pneumatic lines that are required to operate the turbine, as well as the line through which the color to be sprayed is fed to the bell cup 6. These lines are known in the art. The high voltage circuit 3 contains, as well corresponds to the prior art, a measuring resistor 14. This is indicated only schematically in the drawing.
Ein Anschluss dieses Messwiderstandes 14 ist über eine Leitung 9 mit Masse verbunden, der andere über eine Leitung 8 mit dem Turbinengehäuse 7. Die am Messwiderstand 14 abfallende erste Messspannung wird durch eine ebenfalls in der Hochspannungsschaltung 3 vorgesehene Uberwachungs- schaltung ermittelt. Nach dieser ersten Messpannung wird im Betrieb die an den Glockenteller 6 gelegte Hochspannung geregelt. Nach dem Abschalten der HochspannungsSchaltung 3 werden bei Überschreiten eines bestimmten Wertes dieser ersten Messspannung weitere Maßnahmen auslöst. Auch diese Vorgänge sind dem Fachmann bekannt und brauchen daher hier nicht näher beschrieben zu werden. One terminal of this measuring resistor 14 is connected via a line 9 to ground, the other via a line 8 to the turbine housing 7. The falling on the measuring resistor 14 first measuring voltage is determined by a likewise provided in the high-voltage circuit 3 Uberwachungs- circuit. After this first measuring voltage, the high voltage applied to the bell cup 6 is regulated during operation. After switching off the high voltage circuit 3, further measures are triggered when a certain value of this first measuring voltage is exceeded. These processes are known in the art and therefore need not be described in detail here.
Nicht beim Stande der Technik vorhanden dagegen ist Not in the state of the art available, however, is
ein zweiter Messwiderstand 10, der an einem Anschluss ebenfalls mit dem Turbinengehäuse 7 über eine Leitung a second measuring resistor 10, which at a connection also with the turbine housing 7 via a line
11 und an dem anderen Anschluss über eine Leitung 12 mit Masse verbunden ist. Die an dem zweiten Messwiderstand 10 abfallende zweite Messspannung ist daher ebenfalls ein Maß für die Spannung, die am Turbinengehäuse 7 liegt. 11 and at the other terminal is connected via a line 12 to ground. The falling at the second measuring resistor 10 second measuring voltage is therefore also a measure of the voltage, which is located on the turbine housing 7.
Einer Steuereinrichtung 13 werden sowohl die erste als auch die zweite Messspannung zugeführt. Sie vergleicht die über zwei Messkanäle gewonnenen Informationen miteinander. Weichen diese im Ergebnis über einen bestimmten Maximalwert hinaus voneinander ab, so bedeutet dies, dass ein Fehler in einem der beiden Messkanäle vorliegt. A control device 13 is supplied with both the first and the second measuring voltage. It compares the information obtained via two measuring channels with each other. If these deviate from each other in the result beyond a certain maximum value, this means that an error exists in one of the two measuring channels.
In diesem Falle wird ein Störsignal erzeugt, welches das Bedienungspersonal warnt und dieses zu geeigneten Massnahmen veranlasst . Ausserdem kann die Hochspannung automatisch abgeschaltet werden. Stellt die Steuereinrichtung 13 oder die Uberwachungs- Schaltung in der Hochspannungsschaltung 3 einen zu hohen Wert der Spannung am Turbinengehäuse 7 fest, so gibt sie ebenfalls ein geeignetes Störsignal ab, mit dem im Wesentlichen dieselben Wirkungen verbunden sein können, wie oben beschrieben. In this case, an interference signal is generated, which warns the operator and causes it to take appropriate measures. In addition, the high voltage can be switched off automatically. Does the controller 13 or the monitoring Circuit in the high-voltage circuit 3 fixed too high a value of the voltage on the turbine housing 7, so it also emits a suitable noise signal, with the substantially the same effects can be connected, as described above.
