Description

Die vorliegende Erfindung befasst sich mit einer Vorrich­tung zum auswechselbaren Anschliessen eines Abschnittes eines Doseninnenbearbeitungsarmes an diesen Arm und eine Verwendung der Vorrichtung zum Anschliessen eines Dosen­nahtbeschichtungskopfes.The present invention relates to a device for the interchangeable connection of a section of a can processing arm to this arm and a use of the device for connecting a can seam coating head.

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.

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 dies nach dem Wortlaut nach minde­stens einem der Ansprüche, insbesondere nach Anspruch 1, gelöst.According to the invention, this is solved according to the wording according to at least one of the claims, in particular 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 auf­ weisen, 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 that they have plug connections have, which are inserted into each other when merging the contact surfaces.

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 re­ lativ 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 deflection of the section re in the inserted state is possible relative to the arm. 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.

Die erfindungsgemässe Vorrichtung wird anschliessend bei­speilsweise anhand von Figuren beschrieben. Es zeigen:

  • Fig. 1 einen Längsquerschnitt der erfindungsgemässen Vorrichtung,
  • Fig. 2 eine Aufsicht auf eine Kontaktfläche eines Ab­schnittes gemäss der Linie A-A von Fig. 1,
  • Fig. 3 Teile eines Bajonettverschlusses als Verriege­lungsorgan und
  • Fig. 4 einen rutschgesicherten Stecker als Verriege­lungsorgan.
The device according to the invention is then described, for example, with reference to figures. Show it:
  • 1 shows a longitudinal cross section of the device according to the invention,
  • 2 is a plan view of a contact surface of a section along the line AA of FIG. 1,
  • Fig. 3 parts of a bayonet lock as a locking member and
  • Fig. 4 shows a non-slip plug as a locking member.

Fig. 1 ist eine Schnellkupplung zwischen einem Sprüh­arm 1 und einem Anschlussarm 2 einer Dosennahtbeschich­tungsanlage. Sowohl am Sprüharm 1 wie auch am Anschluss­arm 2 sind stirnseitig Kontaktflächen 3 und 4 vorgesehen, die zusammengepresst sind.Fig. 1 is a quick coupling between a spray arm 1 and a connecting arm 2 of a can seam coating system. Contact surfaces 3 and 4, which are pressed together, are provided on the front of both the spray arm 1 and the connecting arm 2.

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 seat 5 of the connecting arm 2, a union nut 8 is rotatably arranged, which engages with an internal thread 10 in an external thread 12 of the spray arm 1. The knobs 9 projecting from the union nut can be pushed over the external thread 12 of the spray arm 1, for example, by being arranged in a resilient manner, for example through axial slots on the union nut 8.

Zu- und Abführleitungen 6 zwischen Sprüharm 1 und An­schlussarm 2 sind dichtend über die Kontaktflächen 3 und 4 verbunden.Supply and discharge lines 6 between spray arm 1 and connecting arm 2 are connected in a sealing manner via contact surfaces 3 and 4.

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 union nut 8 is loosened until the two contact surfaces 3 and 4 can be separated from the spray arm 1 and the connecting arm 2. The spray arm 1, which has been used, for example, to coat larger areas, is now removed and replaced, for example, by a spray arm, for coating smaller areas. The new spray arm 1 is placed with its contact surface 3 on the contact surface 4 of the connecting arm 2. Now the union nut 8 is screwed in and the two contact surfaces 3 and 4 are pressed.

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 on each of the contact surfaces 3 and 4 ensure that the two contact surfaces 3 and 4 must be placed against one another in such a way that the corresponding feed and discharge lines 6 are aligned with one another before they can be pressed. After the new spray arm 1 has been locked by the union nut 8, the line connections are made operationally reliable, such as sealing, by the tensile action of the union nut 8, and the new spray arm 1 can be put into operation.

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 contact surface 3 comprises a sealing ring 16 on its periphery. An electrical connection 6e is established by a commercially available plug socket and a corresponding sleeve in the opposite contact surface. A line 6a is, for example, a light guide. Line 6b is provided for the transport of powder coatings and air, line 6c for the suction of the non-adhering powder. Line 6d for the supply of wet paint is provided in order to enable a powder coating head to be exchanged for a wet paint coating head as a section. The line 6f is provided in order to ventilate a section of a coating head with high-voltage electrodes so that they do not become encrusted with coating medium. For the seal of the connection of the lines 6b, c, d, f, a seal 18 is provided at their mouths in the surfaces 3 or 4, which ensure the connections in a sealed manner.

Wenn nun der Sprüharm mit der Kontaktfläche 3 auf die entsprechende Kontaktfläche des Anschlussarmes gesteckt wird, werden die Positionierstifte 14 in die entspre­chenden Aussparungen in der Kontaktfläche des Anschluss­armes geführt. 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 contact surface 3 is now plugged onto the corresponding contact surface of the connection arm, the positioning pins 14 are guided into the corresponding recesses in the contact surface of the connection arm. Due to the positioning effect of the pins / recesses, corresponding lines 6 are aligned on the contact surfaces and become operationally reliable when locking, e.g. sealing, connected.

In den Fig. 3 und 4 werden weitere Möglichkeiten für das Anschliessen eines Abschnittes an einem Arm durch eine Schnellkupplung dargestellt.3 and 4 show further possibilities for connecting a section to an arm by means of a quick coupling.

In Fig. 3 wird ein Abschnitt 21 an einem Arm 22 unter Verwendung eines Bajonettverschlusses verriegelt. 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 portion 21 is locked to an arm 22 using a bayonet catch. A pin 26 of section 21 is inserted through an insertion recess 27 into a guide 28 of a collar 25 of arm 22. By rotating the section 21, the pin 26 slides along the guide 28 and the two contact surfaces 23 and 24 are pressed together. The pin 26 is fixed in the end position shown in FIG. 3 by means of a terminal recess in the guide 28, as a result of which the two contact surfaces 23 and 24 remain pressed.

In Fig. 4 wird eine Steckverbindung zwischen einem Ab­schnitt 31 und einem Arm 32 dargestellt. Ein Stecker 36 des Abschnittes 31 wird in eine Muffe 35 des Armes 32 eingeführt, bis die Kontaktflächen 33 und 34 aufeinander­treffen. Die Oberfläche 37 des Steckers 36 wie auch die Innenseite 38 der Muffe 35 sind mit einem Material be­schichtet, welches einen hohen Oberflächenreibungswider­stand aufweist. Bedingt durch diesen hohen Oberflächen­reibungswiderstand lassen sich Stecker 36 und Muffe 35 aus der in Fig. 4 gezeigten verriegelten Position nur durch äussere Anwendung von Kraft, beispielsweise durch äusseres Auseinanderziehen der beiden Elemente, entrie­geln.4 shows a plug connection between a section 31 and an arm 32. A plug 36 of the section 31 is inserted into a sleeve 35 of the arm 32 until the contact surfaces 33 and 34 meet. The surface 37 of the plug 36 as well The inside 38 of the sleeve 35 is coated with a material which has a high surface friction resistance. Due to this high surface friction resistance, plug 36 and sleeve 35 can only be unlocked from the locked position shown in FIG. 4 by external application of force, for example by external pulling apart of the two elements.

Die erfindungsgemässe Vorrichtung ist generell auf jeg­liche Art von Innenbearbeitungsanlagen anwendbar, wo die Notwendigkeit des auswechselbaren Anschliessens eines Armabschnittes besteht.The device according to the invention is generally applicable to any type of internal machining system where there is a need to interchangeably connect an arm section.
