Der Druck, mit dem das Reinigungsmedium über den Auslass der wenigstens einen Düse in Richtung des Werkstückträgers ausgebracht wird, ist unter anderem abhängig von der Art der zu behandelnden Werkstücke und kann bis zu 10 bar und mehr betragen.The term "treatment" below means both a cleaning treatment of the workpieces using a liquid cleaning medium and a drying treatment using a gaseous medium. The term "treatment medium" is thus to be understood below as meaning either a liquid cleaning medium, for example water with cleaning additives, preferably cleaning additives based on lye, or a gaseous drying medium, for example air. The pressure with which the cleaning medium is discharged via the outlet of the at least one nozzle in the direction of the workpiece carrier, inter alia, depends on the type of workpieces to be treated and can be up to 10 bar and more.
Der Behandlungsbehälter kann druckfest ausgebildet sein, um die Erzeugung eines Unterdrucks während des Reinigungs- oder Trocknungsprozesses zu ermöglichen, und kann einen verschließbaren oder regelbaren Ablauf für das Reinigungsmedium aufweisen, um die Herstellung eines die Werkstücke umgebenden Reinigungsbades in dem Behandlungsbehälter zu ermöglichen.The treatment container may be pressure-resistant to allow the generation of a negative pressure during the cleaning or drying process, and may have a closable or controllable flow for the cleaning medium to allow the preparation of a cleaning bath surrounding the workpieces in the treatment vessel.
Bei Vorrichtungen nach dem Stand der Technik, bei denen eine Düsenvorrichtung und ein Werkstückträger während des Behandlungsprozesses relativ zueinander um eine gemeinsame Rotationsachse rotieren oder relativ zueinander um die gemeinsame Rotationsachse schwenken, durchläuft die Düse bezogen auf den Werkstückträger eine vorgegebene Kreisbahn, wenn Werkstückträger und/oder Düsenvorrichtung vollständig um 360° rotieoder einen vorgegebenen Abschnitt einer Kreisbahn, wenn Werkstückträger und/oder Düsenvorrichtung in einem vorgegebenen Winkelbereich um die Rotationsachse geschwenkt werden. Es gibt damit Bereiche des durch den Werkstückträger aufgenommenen Werkstücks oder Werkstückkorbes, die nie unmittelbar dem besonders behandlungsaktiven, d.h. reinigungs- oder trocknungsaktiven, Strahl des Behandlungsmediums ausgesetzt sind. Darüber hinaus trifft der Strahl des Behandlungsmediums bei den bekannten Vorrichtungen stets unter dem gleichen Winkel auf die gleichen Abschnitte des Werkstücks oder Werkstückkorbes und wird bei einer rotierenden Relativbewegung des Werkstückträgers und der Düse stets mit der gleichen Geschwindigkeit über gleiche Abschnitte des Werkstückes/Werkstückkorbes geführt.In devices according to the prior art, in which a nozzle device and a workpiece carrier rotate relative to each other during the treatment process about a common axis of rotation or pivot about the common axis of rotation relative to each other, the nozzle passes through a predetermined orbit with respect to the workpiece carrier, if workpiece carrier and / or Nozzle device completely rotatable by 360 ° a predetermined portion of a circular path when workpiece carrier and / or nozzle device are pivoted in a predetermined angular range about the axis of rotation. There are thus areas of the work piece carrier received by the workpiece or workpiece basket, which are never directly exposed to the particularly treatment-active, ie cleaning or drying active, beam of the treatment medium. In addition, in the known devices the jet of the treatment medium always strikes the same sections of the workpiece or workpiece basket at the same angle and is always guided at the same speed over identical sections of the workpiece / workpiece basket during a rotating relative movement of the workpiece carrier and the nozzle.
Die erfindungsgemäße Vorrichtung, bei der eine relative Schwenkbewegung zwischen dem Düsenauslass und dem Werkstückträger um eine Achse parallel zu der Rotationsachse möglich ist, ermöglicht im Vergleich zu bisherigen Vorrichtungen ein effektiveres Behandlungsverfahren bei geringerem Ressourcenaufwand.The inventive device, in which a relative pivoting movement between the nozzle outlet and the workpiece carrier about an axis parallel to the axis of rotation is possible, compared to previous devices allows a more effective treatment process with less resource consumption.
Die Anordnung der Düse und des Werkstückträgers derart, dass die Düse und der Werkstückträger bzw. eine Aufnahmevorrichtung des Werkstückträgers relativ zueinander um eine parallel zu der Rotationsachse verlaufende Achse schwenkbar gelagert sind, ermöglicht eine Variation des Auftreffwinkels zwischen einem aus der Düse austretenden Strahl des Behandlungsmediums und einem durch den Werkstückträger aufgenommen Werkstück/Werkstückkorb in Richtung der rotierenden Relativbewegung zwischen Werkstückträger und Düse.The arrangement of the nozzle and the workpiece carrier such that the nozzle and the workpiece carrier or a receiving device of the workpiece carrier are mounted pivotably relative to each other about an axis parallel to the axis of rotation axis allows a variation of the angle of incidence between a jet emerging from the nozzle of the treatment medium and a workpiece / workpiece basket received by the workpiece carrier in the direction of the rotating relative movement between workpiece carrier and nozzle.
Die schwenkende Relativbewegung zwischen Düsenauslass und Werkstückträger ist bei einer Ausführungsform der erfindungsgemäßen Behandlungsvorrichtung dadurch möglich, dass die Düse an einem Düsenrohr angeordnet ist, das um eine Achse parallel zur Rotationsachse des Werkstückträgers bzw. der Düsenvorrichtung schwenkbar gelagert ist. Bei einer weiteren Ausführungsform der Erfindung ist vorgesehen, dass eine Werkstückaufnahmevorrichtung des Werkstückträgers schwenkbar um eine parallel zur Rotationsachse verlaufende Achse schwenkbar gelagert ist. Darüber hinaus besteht auch die Möglichkeit, die Düse selbst schwenkbar an dem Düsenrohr zu lagern, um eine solche relative Schwenkbewegung zwischen dem Düsenauslass und dem Werkstückträger bzw. der Werkstückaufnahmevorrichtung um eine Achse parallel zu der Rotationsachse zu ermöglichen.The pivoting relative movement between the nozzle outlet and the workpiece carrier is possible in one embodiment of the treatment device according to the invention in that the nozzle is arranged on a nozzle tube which is pivotably mounted about an axis parallel to the axis of rotation of the workpiece carrier or the nozzle device. In a further embodiment of the invention it is provided that a workpiece receiving device of the workpiece carrier is pivotally mounted pivotably about an axis extending parallel to the axis of rotation axis. In addition, there is also the possibility of pivotally supporting the nozzle itself on the nozzle tube in order to allow such a relative pivoting movement between the nozzle outlet and the workpiece carrier or the workpiece receiving device about an axis parallel to the axis of rotation.

Die Düsenvorrichtung 2 gemäß
Darüber hinaus genügt es, für die Düsenvorrichtung 2 nur ein im Wesentlichen parallel zu der Rotationsachse A-A verlaufendes Düsenrohr 22 mit Düsen 4 vorzusehen, weshalb eines der beiden Rohre in
Bei der Vorrichtung gemäß
Der Werkstückträger 3 dient zur Aufnahme eines zu reinigenden Werkstückes 5 oder eines Werkstückkorbes 5 mit darin angeordneten Werkstücken, wobei die Werkstücke in dem Werkstückkorb 5 entweder Schüttgut oder vereinzelte Werkstücke sein können.
Mit x wird nachfolgend die Richtung der Rotationsachse A-A bezeichnet, und mit α wird nachfolgend ein Winkel bezeichnet, den eine den Düsenauslass 41 verlängernde Gerade bzw. ein aus dem Düsenauslass 41 der Düse 4 austretender Behandlungsstrahl, der in
Bei bekannten Vorrichtungen sind die Düsenauslässe 41 der Düsen 4 so angeordnet, dass die Behandlungsstrahlen zentral auf die Rotationsachse A-A gerichtet sind, so dass für diese bekannten Vorrichtungen γ = 0 gilt.In known devices, the
Während des mit der Vorrichtung gemäß
Neben dieser relativen Rotationsbewegung zwischen Düsenvorrichtung 2 bzw. Düse 4 und Werkstückträger 3 ermöglicht die zu Zwecken der Veranschaulichung dargestellte Behandlungsvorrichtung eine lineare Relativbewegung zwischen den Düsen 4 bzw. den Düsenauslässen 41 und dem Werkstückträger 3 bzw. dem durch den Werkstückträger 3 aufgenommenen Werkstück/Werkstückkorb 5 in Richtung der Rotationsachse A-A.In addition to this relative rotational movement between
Diese lineare Relativbewegung wird bei der Behandlungsvorrichtung gemäß
Durch die relative Beweglichkeit zwischen Düsenauslass 41 und Werkstückträger 3 in Richtung der Rotationsachse A-A ist ein deutlich vergrößerter Bereich vorhanden, der unmittelbar über die Düsen 4 mit Behandlungsmedium beaufschlagt werden kann. Während der rotierenden Relativbewegung zwischen Düse 4 und Werkstückträger 3 werden die Düse 4 und der Werkstückträger 3 vorzugsweise periodisch in Richtung der Rotationsachse hin- und herbewegt, was nachfolgend erläutert wird.Due to the relative mobility between the
Mit x0 sei bezugnehmend auf
Während des Behandlungsverfahrens wird die Düse 4 bzw. der Düsenauslass 41 relativ zu dem Werkstück/Werkstückkorb 5 um diesen Hub Δx periodisch hin- und herbewegt. Dieser periodischen linearen Relativbewegung überlagert sich die rotierende Relativbewegung zwischen dem durch den Werkstückträger 3 aufgenommenen Werkstück/Werkstückkorb 5 und der Düse 4.
Im Gegensatz zu Vorrichtungen, bei denen die Düse 4 unabhängig von der Winkelposition der relativen Rotation zwischen Düse 4 und Werkstück 5 in Richtung der Rotationsachse A-A immer die Position x0 einnimmt, überstreicht der Reinigungsstrahl bei der erläuterten Behandlungsvorrichtung betrachtet über mehrere Umdrehungen einen wesentlich größeren Bereich des Werkstückes/Werkstückkorbes 5. Hierdurch können gegenüber herkömmlichen Vorrichtungen sogar Reinigungsdüsen eingespart werden, was in der eingangs erläuterten Weise zu einem verringerten Ressourcenaufwand führt. Darüber hinaus führt die Tatsache, dass der Reinigungsstrahl in x-Richtung periodisch seine Richtung ändert, zu einem zusätzlichen behandlungsaktiven Effekt, insbesondere während eines Reinigungsverfahrens, bei dem Reinigungsflüssigkeit aus den Düsen auf das Werkstück/den Werkstückkorb 5 abgegeben wird. Die Geschwindigkeit, mit der die Düse 4 und das Werkstück/der Werkstückkorb 5 relativ zueinander in Richtung der Rotationsachse A-A hin- und herbewegt werden, kann bis zum Umkehrpunkt der Oszillationsbewegung jeweils konstant sein. Darüber hinaus besteht auch die Möglichkeit, diese Geschwindigkeit der relativen Linearbewegung zwischen der Düse 4 und dem Werkstück /Werkstückkorb 5 innerhalb eines Bewegungszyklusses zu variieren.In contrast to devices in which the

Der verschiebbare Abschnitt 222 weist einen geringeren Durchmesser als der feste Abschnitt 221 auf und ist mit einem Ende innerhalb des festen Abschnittes 221 angeordnet. Der verschiebbare Abschnitt 222 weist an diesem einen Ende einen Ansatz bzw. einen Flansch 225 auf, wobei dieser Ansatz 225 in Verbindung mit Ansätzen bzw. Flanschen des festen Rohrabschnittes 221 dazu dient, die Verschiebung des zweiten Rohrabschnittes 222 innerhalb des ersten Rohrabschnittes 221 zu begrenzen. Der Abstand der beiden Flansche bzw. Ansätze 223, 224 des festen Rohrabschnittes 221 bestimmt den Hub der linearen Relativbewegung der Düsen 4 bzw. Düsenauslässe 41 relativ zu dem Werkstück/Werkstückkorb 5 in Richtung der Rotationsachse A-A.The
Insbesondere zur Verstärkung des Reinigungseffektes bei Durchführung einer Reinigungsbehandlung kann die Rotationsgeschwindigkeit, mit welcher die Düse 4 und das Werkstück/der Werkstückkorb 5 relativ zueinander rotieren, variieren. Diese Variation der Winkelgeschwindigkeit dϕ/dt erfolgt vorzugsweise periodisch, wie in

Die Auslenkung des Düsenrohres 22, durch die die einzelnen Düsen 4 um die Achse B-B geschwenkt werden, führt zum Einen dazu, dass sich der Auftreffwinkel, unter dem ein aus einer Düse 4 austretender Behandlungsstrahl auf eine Oberfläche des Werkstücks/Werkstückkorbes 5 trifft, ändert. Insbesondere bei Durchführung eines Reinigungsverfahrens resultiert hieraus ein positiver Reinigungseffekt, da beispielsweise Verunreinigungen in Aussparungen von Werkstücken manchmal erst dann entfernt werden können, wenn der Reinigungsstrahl unter einem Winkel ungleich 90° auf das Werkstück auftrifft. Darüber hinaus führt die Schwenkbewegung der Düsen 4 in Bezug auf das Werkstück/den Werkstückträger 5 dazu, dass mittels einer einzelnen Düse 4 ein größerer Behandlungsbereich auf dem Werkstück 5 erreicht wird, wodurch gegebenenfalls Düsen 4 im Vergleich zu herkömmlichen Behandlungsvorrichtungen eingespart werden können.The deflection of the

Während der rotierenden Relativbewegung zwischen Düse und Werkstück 5 wird die Düsenvorrichtung 2 periodisch ausgelenkt, um die Düse 4 periodisch relativ zu dem Werkstück/Werkstückkorb 5 zu schwenken.

Die Düsenvorrichtung 2 mit den Düsen 4 kann dabei ebenfalls um die Rotationsachse A-A rotieren oder kann starr bleiben.If, in this treatment device, the

Die erfindungsgemäße Vorrichtung ermöglicht ein Behandlungsverfahren, bei dem ein Winkel, unter dem ein Behandlungsmedium auf das Werkstück auftrifft und/oder eine Geschwindigkeit, mit der der Behandlungsstrahl über das Werkstück geführt wird, permanent variiert, wodurch ein besonders behandlungsaktiver Effekt erzielt wird. Es wird damit eine permanente vektorielle Änderung der Richtung, in welcher ein Behandlungsstrahl das Werkstück überstreicht, und/oder des Winkels, unter welchem der Behandlungsstrahl auf das Werkstück auftrifft, erreicht, wodurch auch Werkstücke mit komplizierten Oberflächengeometrien effektiv gereinigt werden können.The device according to the invention makes possible a treatment method in which an angle at which a treatment medium impinges on the workpiece and / or a speed, with which the treatment beam is guided over the workpiece, permanently varied, whereby a particularly treatment-active effect is achieved. It is thus achieved a permanent vectorial change in the direction in which a treatment beam passes over the workpiece, and / or the angle at which the treatment beam impinges on the workpiece, whereby workpieces with complicated surface geometries can be effectively cleaned.
