Abstract
Description
Die Erfindung betrifft ein Dosiersystem für eine Beschichtungsvorrichtung gemäß dem Oberbegriff der unabhängigen Patentansprüche 1 und 3.The invention relates to a metering system for a coating device according to the preamble of the independent claims 1 and 3.
Insbesondere handelt es sich um ein Dosiersystem für an Robotern oder sonstigen Beschichtungsmaschinen montierte Zerstäuber für die Serienbeschichtung von Werkstücken wie beispielsweise Fahrzeugkarossen. Bekannte Beschichtungsmaschinen dieser Art oder deren Zerstäuber enthalten mechanisch von einem elektromechanischen Spindelantrieb betätigte Dosierzylinder (
Es sind zwar auch schon Zerstäuber mit hydraulisch angetriebenen Kolben-Zylindereinheiten bekannt (
Probleme hinsichtlich Dosiergenauigkeit und Dynamik ergeben sich auch bei anderen bekannten Zerstäubern mit Zylinderbehältern für das Beschichtungsmaterial, deren Kolben durch Druckluft angetrieben wird (

Aufgabe der Erfindung ist, ein einfaches, kompakt zu bauendes Dosiersystem der betrachteten Gattung anzugeben, das mit hoher Dosiergenauigkeit und bei Sollwertänderungen mit höchstmöglicher Dynamik arbeitet.The object of the invention is to provide a simple, compact to be built dosing of the type considered, which works with high dosing accuracy and setpoint changes with the highest possible dynamics.
Diese Aufgabe wird durch das in den Patentansprüchen angegebene Dosiersystem gelöst.This object is achieved by the metering system specified in the claims.
Im Gegensatz zu bekannten Dosierzylindern mit Druckluftantrieb wirkt erfindungsgemäß die erste Antriebseinrichtung, vorzugsweise eine pneumatische oder mechanische Druckeinrichtung, nur als Vorspanneinrichtung für den Kolbenantrieb. Die eigentliche Dosierung erfolgt durch das Zugelement, das nur eine zu dem Vorspanndruck entgegengesetzte Kraft auf den Kolben ausübt und dessen durch diesen Vordruck bewirkte Bewegung in genau dem gewünschten Maße zulässt. Da alle mechanischen Übertragungselemente zwischen dem Kolben und der die Ausflussmenge des Beschichtungsmaterials bestimmenden mechanischen zweiten Antriebseinrichtung unter ständiger Zugbelastung stehen, entfallen die Toleranzen der bekannten elektromechanischen Kolbenantriebe, so dass sich eine wesentlich genauere Dosierung ergibt. Zugleich folgt das System aufgrund des Vordrucks direkt, schlupffrei und schnell auch sprunghaften Sollwertänderungen.In contrast to known metering cylinders with compressed air drive, according to the invention, the first drive device, preferably a pneumatic or mechanical pressure device, acts only as a pretensioning device for the piston drive. The actual dosage is carried out by the tension element, which exerts only a force opposite to the biasing force on the piston and its caused by this form allows movement in exactly the desired extent. Since all mechanical transmission elements between the piston and the outflow of the coating material determining mechanical second drive means are under constant tensile load, eliminating the tolerances of the known electromechanical piston actuators, so that there is a much more accurate metering. At the same time, the system follows directly due to the form directly, slip-free and fast also sudden set point changes.
Aufgrund der möglichen kompakten Bauweise eignet sich das hier beschriebene Dosiersystem besonders vorteilhaft für den Einbau in Zerstäuber und räumlich begrenzte Bereiche von Beschichtungsmaschinen.Due to the possible compact design, the metering system described here is particularly advantageous for installation in atomizers and spatially limited areas of coating machines.
An dem in der Zeichnung schematisch und vereinfacht dargestellten Ausführungsbeispiel wird die Erfindung näher erläutert.The invention is explained in more detail in the exemplary embodiment illustrated schematically and simplified in the drawing.
Das dargestellte Dosiersystem enthält einen zylinderartigen Behälter 1, in dem ein Kolben 2 längs der Zylinderachse verschiebbar gelagert ist. Der Kolben 2 unterteilt den Behälterinnenraum in einen ersten Bereich 4 für die Antriebsenergie des Systems auf der in der Zeichnung oberen Seite und einen zweiten Bereich 3, in dem sich das zu dosierende Beschichtungsmaterial wie z. B. Farblack befindet. Als Antriebsmedium kann zweckmäßig Druckluft dienen, die von einer Quelle 5 durch einen Lufteinlass 10 kommend bei dem dargestellten Beispiel den ersten Behälterbereich 4 unter Druck setzt, dadurch den Kolben 2 in Richtung zu dem zweiten Behälterbereich 3 beaufschlagt und folglich das System in dieser Kraftrichtung vorspannt. Statt Druckluft können auch andere gasförmige oder auch flüssige Druckmedien verwendet werden, die im Gegensatz etwa zu den mit Dosierflüssigkeit arbeitenden bekannten Systemen nicht dosiert zugeführt werden müssen. Statt eines Druckmediums kann zur Erzeugung der Antriebs- oder Vorspannkraft für den Kolben aber auch eine mechanische Druck- oder Zugeinrichtung insbesondere mit einer Feder vorgesehen sein.The dosing system shown contains a cylinder-like container 1, in which a
An einer unkontrollierten Bewegung aufgrund der bei dem dargestellten Beispiel vorgesehenen Druckbeaufschlagung wird der Kolben 2 von einem auf der Seite des ersten Bereiches 4 an dem Kolben angreifenden flexiblen Zugelement 6 gehindert, bei dem es sich um ein zugfestes und nicht längselastisches oder dehnbares Draht-, Flachband- oder Kettenglied od. dgl. aus Metall oder Kunststoff handeln kann. Das Zugelement 6 ist durch eine Öffnung 11 aus dem Behälter 1 herausgeführt und kann außerhalb des Behälters über Rollen 12, 12' in eine zweckmäßige Richtung beispielsweise parallel zur Bewegungsrichtung des Kolbens 2 umgelenkt werden. Das Zugelement 6 hat die Funktion, dem Kolbendruck zur Steuerung der Kolbenbewegung entsprechend der gewünschten Ausflussmenge nachzugeben, und ist zu diesem Zweck an seinem dem Kolben 2 abgewandten Ende mit einer programmgesteuerten elektromechanischen Antriebseinheit 7 verbunden. Bei dem dargestellten Beispiel ist das flexible Zugelement 6 an dem Gewinderad 13 einer Spindel 14 befestigt, die von einem Servomotor oder sonstigen programmgesteuerten elektrischen Motor 15 angetrieben wird. Der Motor 15 ist umsteuerbar, so dass beim Zurückfahren des Kolbens 2 in Richtung zum ersten Bereich 4 nach Beendigung eines Beschichtungsvorgangs das Zugelement 6 im entsprechenden Maße wieder aus dem Behälter 1 herausgezogen werden kann.In an uncontrolled movement due to the pressure applied in the illustrated example, the
Statt der Linear- oder translatorischen Antriebseinheit 7 des dargestellten Beispiels können auch andere Einrichtungen zur Steuerung der Folgebewegung des Zugelements 6 dienen, beispielsweise eine rotatorische Antriebseinheit mit einem Aufrollmechanismus zum Auf- und Abwickeln des Zugelements 6 während der Hin- und Herbewegung des Kolbens 2 in dem Behälter 1.Instead of the linear or translatory drive unit 7 of the illustrated example, other means for controlling the following movement of the
Wenn der Behälterbereich 4 unter Druck gesetzt werden soll, muss er gegen die Umgebung des Behälters abgedichtet sein. Zur Abdichtung an der Stelle der Herausführung des Zugelementes 6 aus dem Behälter 1 kann es genügen, beispielsweise einen das Zugelement bildenden Runddraht durch eine Dichtmanschette an der Öffnung 11 zu führen. In anderen Fällen kann es aber zweckmäßiger sein, auf eine Abdichtung der Herausführung 11 zu verzichten, auch um dem Zugelement 6 eine möglichst freie Bewegung zu ermöglichen, und dessen Weg bis zum Kolben 2 gegen die Umgebung offen, also druckfrei zu gestalten. Bei dem dargestellten Beispiel ist das Zugelement 6 zu diesem Zweck von einer längs der Bewegungsrichtung des Kolbens 2 beweglichen, beispielsweise balgartigen Umhüllung 17 umschlossen, die gegen den unter Druck setzbaren Behälterbereich 4 abdichtend an ihrem einen Ende an dem Kolben 2 und an ihrem anderen Ende an der die Herausführungsöffnung 11 umgebenden Wand des Behälters 1 befestigt ist.If the
In Abwandlung des beschriebenen Beispiels bestehen auch andere Möglichkeiten für die Druckbeaufschlagung des Kolbens in dem ersten Behälterbereich 4. Statt den Behälterbereich 4 selbst unter Druck zu setzen, kann man beispielsweise auch einen unter Druck setzbaren und dadurch expandierenden Balg od. dgl. einbauen, der den Kolben 2 in Richtung zu dem zweiten Behälterbereich 3 drückt.In a modification of the example described, there are other possibilities for pressurizing the piston in the
Der das Beschichtungsmaterial enthaltende Behälterbereich 3 hat eine Materialauslassöffnung 19, an die eine zu dem Zerstäubungsorgan 20 des Zerstäubers, in den der Behälter 1 und vorzugsweise auch die anderen Bestandteile des Dosiersystems einschließlich der Antriebseinheit 7 vorteilhaft eingebaut sein können, führende Leitung angeschlossen ist. Das Zerstäubungsorgan 20 kann beispielsweise der Glockenteller eines elektrostatischen Rotationszerstäubers oder die Düse eines Luftzerstäubers od. dgl. sein.The container area 3 containing the coating material has a material outlet opening 19, to which a line leading to the atomizing device 20 of the atomizer, into which the container 1 and preferably also the other components of the metering system including the drive unit 7 can be advantageously installed, is connected. The atomizing member 20 may be, for example, the bell cup of an electrostatic rotary atomizer or the nozzle of an air atomizer or the like.
Nach Beendigung eines Beschichtungsvorgangs, bei dem der Kolben 2 den Behälterbereich 3 ganz oder teilweise entleert hat, wird er wieder in seine Ausgangsstellung zurückgeschoben. Das kann durch den Druck des Farb- oder sonstigen Beschichtungsmaterials bewirkt werden, das beim Einfüllvorgang u. U. durch die Auslassöffnung 19, vorzugsweise aber durch eine zusätzliche in den Bereich 3 führende Einlassöffnung gemäß dem Pfeil 21 in den Behälter 1 geleitet wird. Das Zugelement 6 wird im gleichen Maße von der Antriebseinheit 7 zurückgezogen. Eine andere Möglichkeit besteht darin, dass die Antriebseinheit 7 den Kolben 2 gegen den auch beim Einfüllvorgang wirkenden Druck der Quelle 5 zurückzieht, wobei sich der dadurch freiwerdende Bereich 3 mit dem Beschichtungsmaterial füllt.After completion of a coating process in which the
