Description
Die Vorliegende Erfindung betrifft eine Vorrichtung für die Doseninnenbearbeitung mit einem Dosenninnenbearbeitungsarm, umfassend einen Anschlussarm und einen Abschnitt mit Sprühkopf für die Innenbeschichtung von Dosen sowie eine Verwendung der Vorrichtung zum Anschliessen eines Dosennahtbeschichtungskopfes an einem Arm einer Dosennahtinnenbeschichtungsanlage.The present invention relates to an apparatus for internal can processing with an internal canning arm, comprising a connecting arm and a section with a spray head for the internal coating of cans, and to a use of the apparatus for connecting a can seam coating head to an arm of an internal seam coating system.
Bei Doseninnenbeschichtungsanlagen werden zum Beschichten verschiedene Sprühköpfe resp. Sprüharme, sowohl für die Applikation von Pulverlacken wie auch von Nasslacken, verwendet. Allgemeiner muss des öfteren bei Doseninnenbearbeitungsanlagen, wie z.B. auch bei Anlagen für die Verschmelzung von aufgetragenem Pulver am Doseninnern, die Arbeitsstation am ins Doseninnere einragenden Arm ausgewechselt werden.In the case of interior coating systems for cans, various spray heads or Spray arms, used for the application of powder coatings as well as wet coatings. More generally, internal canning systems, such as also in systems for melting applied powder on the inside of the can, the work station on the arm protruding into the inside of the can can be replaced.
Bei heute verwendeten Doseninnenbeschichtungsanlagen sind die Sprüharme wohl auswechselbar. Allerdings dauert der Auswechselvorgang relativ lange, da alle Zu- und Abführleitungen für das Beschichtungsmedium, für Luft, für Strom usw. einzeln getrennt, resp. wieder verbunden werden müssen, bevor der neue Sprüharmabschnitt auf den Arm der Beschichtungsanlage aufgesteckt und dort verriegelt werden kann.In the case of interior can coating systems used today, the spray arms are probably interchangeable. However, the replacement process takes a relatively long time, since all supply and discharge lines for the coating medium, for air, for electricity etc. are individually separated, or. must be reconnected before the new spray arm section can be attached to the arm of the coating system and locked there.
So ist beispielsweise in der DE-OS 2 236 140 eine konventionelle Doseninnenbeschichtungsanlage beschrieben, wie sie noch aus einer Reihe von ähnlich gelagerten Patentschriften oder technischen Veröffentlichungen bekannt ist. Falls nun in der beschriebenen Beschichtungsanlage beispielsweise ein anderes Beschichtungsmedium auf die Doseninnenseite appliziert werden muss, ist dies normalerweise mit dem selben Sprühkopf nicht möglich, womit bei Beschichtungsanlagen der in der DE-OS 2 236 140 beschriebenen Art auf komplizierte und zeitintensive Art und Weise der gesamte Sprüharm abmontiert werden muss, um durch einen anderen Arm ersetzt zu werden.For example, DE-OS 2 236 140 describes a conventional internal coating system for cans as is known from a number of similarly arranged patents or technical publications. If, for example, another coating medium has to be applied to the inside of the can in the coating system described, this is normally not possible with the same spray head, which means that the whole of the coating systems of the type described in DE-OS 2 236 140 in a complicated and time-consuming manner Spray arm must be removed to be replaced by another arm.
In der DE-A 3 215 372 wird eine Steckverbindung für medizinische und zahntechnische Geräte beschrieben, wobei sowohl elektrische Steckverbindungen als auch Schlauchverbindungen steckbar herzustellen sind. Zwischengeschaltet zwischen den beiden zu verbindenden Teilen ist eine gelochte Kunststoffscheibe angeordnet, die als Dichtungsscheibe dient, wobei je ein Steckende von einer der zu verbindenden Leitungen durch ein entsprechendes Loch der Scheibe hindurch in einen Trichter am anderen Steckende hindurchragt, wobei der Trichter dichtend an die Scheibe gepresst wird. Diese für medizinische und zahntechnische Verhältnisse wohl geeignete Steckverbindung ist in ihrem Aufbau recht kompliziert und dürfte als Steckverbindung für das schnelle Auswechseln von Doseninnenbeschichtungsarmen kaum geeignet sein. Die bei der Beschichtung verwendeten Medien, wie Nasslacke, Pulverlacke, etc. stellen sehr hohe Anforderungen an einen Anschluss des Beschichtungsarmes an die Beschichtungsanlage, was sich ja deutlich auch aus der doch massiven Konstruktion zeigt, wie sie in der DE-OS 2 236 140 vorgeschlagen wird.DE-A 3 215 372 describes a plug-in connection for medical and dental technology devices, both electrical plug-in connections and hose connections being pluggable. Interposed between the two parts to be connected is a perforated plastic washer, which serves as a sealing washer, with one plug end of each of the lines to be connected protruding through a corresponding hole in the washer and into a funnel at the other plug end, the funnel sealing against the washer is pressed. This connector, which is well suited for medical and dental technology, is quite complicated in its structure and should hardly be suitable as a connector for the quick replacement of inner coating arms. The media used in the coating, such as wet paints, powder coatings, etc., place very high demands on connecting the coating arm to the coating system, which is clearly evident from the massive construction, as proposed in DE-OS 2 236 140 becomes.
Die Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zu schaffen, die das schnelle Auswechseln eines solchen Abschnittes in einer Doseninnenbearbeitungsanlage ermöglicht.The object of the present invention is therefore to provide a device which enables the rapid replacement of such a section in an internal can processing system.
Erfindungsgemäss wird diese Aufgabe nach dem Wortlaut gemäss Anspruch 1 gelöst.According to the invention, this object is achieved according to the wording according to claim 1.
Eine erfindungsgemässe Vorrichtung umfasst dabei vorzugsweise je eine ebene oder gekrümmte Kontaktfläche am Abschnitt, wie beispielsweise am Sprüharm, und am Arm der Anlage, auf den der Abschnitt angeschlossen wird, sowie mindestens ein Verriegelungsorgan, das die Kontaktflächen zusammenpresst.A device according to the invention preferably comprises a flat or curved contact surface on the section, such as on the spray arm, and on the arm of the system to which the section is connected, and at least one locking element that presses the contact surfaces together.
Damit der auswechselbare Abschnitt, wie beispielsweise der Sprüharm, positionsrichtig auf den Arm der Doseninnenbearbeitungsanlage angeschlossen wird, sind weiter vorzugsweise an den Kontaktflächen Positionierorgane vorgesehen, die das verriegelnde Betätigen des Verriegelungsorganes nur in einer vorgegebenen Relativposition der beiden Flächen zulassen.So that the interchangeable section, such as the spray arm, is connected in the correct position to the arm of the can processing system, positioning elements are further preferably provided on the contact surfaces, which allow the locking actuation of the locking element only in a predetermined relative position of the two surfaces.
Beim Anschliessen des Abschnittes, wie des Sprüharmes an den Arm der Doseninnenbearbeitungsanlage, ist es wichtig, dass auch die Verbindung der Zu- und Abführleitungen, wie beispielsweise für das Beschichtungsmedium, für Strom, für Messgeräteanschlüsse usw., erstellt wird. Dies wird nun dadurch erreicht, dass die Anschlüsse zwischen Arm und dem Abschnitt durch die Verriegelung mittels des Verriegelungsorganes betriebssicher verbunden werden. Dies beispielsweise dadurch, dass die Leitungen entweder beim positionsrichtigen Zusammenführen der Kontaktflächen dichtend aneinanderliegen oder dass sie Steckverbindungen aufweisen, die beim Zusammenführen der Kontaktflächen ineinandergesteckt werden.When connecting the section, such as the spray arm, to the arm of the can processing system, it is important that the connection of the supply and discharge lines, such as for the coating medium, for electricity, for measuring device connections, etc., is also established. This is now achieved in that the connections between the arm and the section are connected in an operationally reliable manner by the locking by means of the locking member. This is done, for example, in that the lines either lie tightly against one another when the contact surfaces are brought together in the correct position, or in that they have plug connections, which are inserted into each other when the contact surfaces are brought together.
Beim raschen Auswechseln des Abschnittes kann es vorkommen, dass die Kontaktflächen verunreinigt sind, so dass ein dichtes Zusammenpressen der beiden Kontaktflächen erschwert wird. Deshalb und zur Erstellung einer federnden Verriegelung wird weiter vorgeschlagen, mindestens einen Dichtungsring, beispielsweise an der Peripherie einer der Kontaktflächen, anzuordnen, um durch die Verriegelung die Flächen in der Trennebene dichtend zu verbinden. In diesem Fall brauchen die Kontaktflächen im verpressten Zustand nicht direkt aufeinanderzuliegen.When the section is exchanged quickly, it can happen that the contact surfaces are contaminated, so that a tight compression of the two contact surfaces is made more difficult. For this reason and to create a resilient locking, it is further proposed to arrange at least one sealing ring, for example on the periphery of one of the contact surfaces, in order to seal the surfaces in the parting plane by the locking. In this case, the contact surfaces do not need to lie directly on top of one another in the pressed state.
Um die Kontaktflächen gegeneinander zu verpressen, wird einfacherweise vorgeschlagen, eine Ueberwurfmutter als Verriegelungsorgan zu verwenden. Vorzugsweise ist diese Ueberwurfmutter derart ausgestaltet, dass bereits ein Drehen um einen relativ kleinen Winkel die Verriegelung garantiert.In order to press the contact surfaces against one another, it is simply proposed to use a union nut as a locking member. This union nut is preferably designed in such a way that turning it by a relatively small angle guarantees the locking.
In einer weiteren Ausführungsvariante wird vorgeschlagen, einen Bajonettverschluss einzusetzen mit dem Verriegelungsorgan als Teil davon.In a further embodiment variant, it is proposed to use a bayonet lock with the locking member as part of it.
In einer weiteren Ausführungsvariante wird vorgeschlagen, das Verriegelungsorgan als rutschgesicherten Stecker auszubilden. Dabei muss die Länge des Steckers resp. der dazu korrespondierenden Muffe derart ausgebildet sein, dass im gesteckten Zustand keine Auslenkung des Abschnittes relativ zum Arm möglich ist. Vorzugsweise wird dabei entweder die Oberfläche des Steckers oder die Innenseite der Muffe mit einem Material mit hoher Oberflächenreibung ausgebildet, dass ein möglichst hoher Reibungswiderstand zwischen Muffe und Stecker entsteht. Bei dem Material kann es sich beispielsweise um Kunststoff oder um kautschukartige Materialien handeln. Ein Auseinanderziehen von Muffe und Stecker ist nur durch die Einwirkung einer äusseren Kraft möglich.In a further embodiment variant, it is proposed to design the locking member as a non-slip plug. The length of the plug or. of the corresponding sleeve can be designed such that no displacement of the section relative in the inserted state to the arm is possible. Preferably, either the surface of the connector or the inside of the sleeve is formed with a material with high surface friction, so that the highest possible frictional resistance between the sleeve and connector. The material can be plastic or rubber-like materials, for example. The sleeve and plug can only be pulled apart by the action of an external force.
Die erfindungsgemässe Vorrichtung eignet sich insbesondere zum Anschliessen eines Dosennahtbeschichtungskopfes als Abschnitt an einen Arm einer Doseninnenbeschichtungsanlage.The device according to the invention is particularly suitable for connecting a can seam coating head as a section to an arm of a can coating system.

Auf einem Gleitsitz 5 des Anschlussarmes 2 ist eine Ueberwurfmutter 8 drehbar angeordnet, die mit einem Innengewinde 10 in ein Aussengewinde 12 des Sprüharmes 1 eingreift. Die an der Ueberwurfmutter vorstehenden Noppen 9 können beispielsweise derart über das Aussengewinde 12 des Sprüharmes 1 geschoben werden, indem sie federnd, beispielsweise durch achsiale Schlitze an der Ueberwurfmutter 8, angeordnet sind.On a sliding

Beim Auswechseln des Sprüharmes 1 wird die Ueberwurfmutter 8 gelöst, bis sich die beiden Kontaktflächen 3 und 4 von Sprüharm 1 und Anschlussarm 2 trennen lassen. Der Sprüharm 1, welcher beispielsweise für die Beschichtung grösserer Flächen gedient hat, wird nun entfernt und beispielsweise durch einen Sprüharm, für die Beschichtung von kleineren Flächen, ersetzt. Der neue Sprüharm 1 wird mit seiner Kontaktfläche 3 an die Kontaktfläche 4 des Anschlussarmes 2 gelegt. Nun wird die Ueberwurfmutter 8 eingeschraubt und die beiden Kontaktflächen 3 und 4 verpresst.When the spray arm 1 is replaced, the
Durch Positionierstifte 14 (Fig. 2) und entsprechende Bohrungen je an den Kontaktflächen 3 und 4 wird sichergestellt, dass die beiden Kontaktflächen 3 und 4, bevor sie verpresst werden können, derart aneinandergelegt werden müssen, dass die entsprechenden Zu- und Abführleitungen 6 aufeinanderfluchten. Nach Verriegelung des neuen Sprüharmes 1 durch die Ueberwurfmutter 8 sind die Leitungsverbindungen durch Zugwirkung der Ueberwurfmutter 8 betriebssicher, wie dichtend, erstellt, und der neue Sprüharm 1 kann in Betrieb genommen werden.Positioning pins 14 (FIG. 2) and corresponding bores each on the
Wie aus Fig. 2 ersichtlich, umfasst die Kontaktfläche 3 an ihrer Peripherie einen Dichtungsring 16. Eine elektrische Verbindung 6e wird durch eine handelsübliche Steckbuchse und eine entsprechende Muffe in der gegenüberliegenden Kontaktfläche erstellt. Bei einer Leitung 6a handelt es sich beispielsweise um einen Lichtleiter. Leitung 6b ist für den Transport von Pulverlacken und Beförderungsluft vorgesehen, Leitung 6c für die Absaugung des nicht haftenden Pulvers. Leitung 6d für die Zufuhr von Nasslack ist vorgesehen, um zu ermöglichen,einen Pulverbeschichtungs- gegen einen Nasslackbeschichtungskopf als Abschnitt auszuwechseln. Die Leitung 6f ist vorgesehen, um an einem Beschichtungskopf als Abschnitt mit Hochspannungselektroden letztere zu umlüften, damit sie nicht durch Beschichtungsmedium verkrusten. Für die Dichtung der Verbindung der Leitungen 6b, c, d, f sind an ihren Mündungen in die Flächen 3 oder 4 je eine Dichtung 18 vorgesehen, die die Verbindungen dichtend sicherstellen.As can be seen from FIG. 2, the

Aufgrund der Positionierwirkung der Stifte/Aussparungen fluchten entsprechende Leitungen 6 an den Kontaktflächen und werden beim Verriegeln betriebssicher, z.B. dichtend, verbunden.If the spray arm with the

Ein Stift 26 des Abschnittes 21 wird durch eine Einführaussparung 27 in eine Führung 28 eines Ueberwurfringes 25 des Armes 22 eingeführt. Durch Drehen des Abschnittes 21 gleitet der Stift 26 entlang der Führung 28, und die beiden Kontaktflächen 23 und 24 werden aneinandergepresst. Durch eine endständige Aussparung in der Führung 28 wird der Stift 26 in der in Fig. 3 gezeigten Endstellung fixiert, wodurch die beiden Kontaktflächen 23 und 24 verpresst bleiben.In Fig. 3, a
