Description

Die Erfindung betrifft eine Beschichtungsvorrichtung zum thermischen Beschichten, mit einer Beschichtungseinrichtung und mit einer Materialvorschubeinrichtung, wobei die Beschichtungseinrichtung eine Spritzpistole und eine Spritzpistolenhalterung aufweist, wobei die Spritzpistole mit der Spritzpistolenhalterung verbunden ist, wobei die Spritzpistole funktional wirksam mittels mindestens eines Antriebsmittels beim Beschichten um eine Achse rotierbar ist und/oder in Axialrichtung verfahrbar ist, wobei mit der Spritzpistole ein Beschichtungswerkstoff auf eine Innenfläche eines hohlen Werkstücks auftragbar ist.The invention relates to a coating device for thermal coating, with a coating device and with a material feed device, wherein the coating device comprises a spray gun and a spray gun holder, wherein the spray gun is connected to the spray gun holder, the spray gun functionally effective by means of at least one drive means when coating around an axis is rotatable and / or movable in the axial direction, wherein the spray gun, a coating material can be applied to an inner surface of a hollow workpiece.

Thermisches Beschichten umfasst Verfahren, bei denen ein Beschichtungswerkstoff innerhalb oder außerhalb einer Spritzpistole an-, auf oder abgeschmolzen und auf eine vorbereitete Werkstückfläche aufgeschleudert wird. Thermisches Beschichten umfasst unter anderem folgende Hauptverfahren: Plasmaspritzen, Hochgeschwindigkeitsflammspritzen, Pulverflammspritzen, Drahtflammspritzen, Lichtbogendrahtspritzen, Laserspritzen, Detonationsspritzen, Kaltgasspritzen.Thermal coating includes methods in which a coating material is applied, melted or melted inside or outside a spray gun and spin-coated onto a prepared workpiece surface. Thermal coating includes, but is not limited to, the following main processes: plasma spraying, high velocity flame spraying, powder flame spraying, wire flame spraying, electric arc wire spraying, laser spraying, detonation spraying, cold gas spraying.

Aus der DE 102 04 251 A1 ist eine Beschichtungsvorrichtung zum thermischen Beschichten, nämlich zum Lichtbogendrahtspritzen von Bohrungen bekannt. Die Beschichtungsvorrichtung weist eine Beschichtungseinrichtung und eine Drahtvorschubeinrichtung auf. Die Beschichtungseinrichtung weist eine Spritzpistole in Form eines hohlzylindrischen Grundkörpers auf. Der Grundkörper bildet ferner einen Teil der Drahtvorschubeinrichtung. Die Spritzpistole ist drehbar an einer Spritzpistolenhalterung angeordnet. Die Drahtvorschubeinrichtung und die Spritzpistoleneinrichtung bilden eine starre, rotierbare Baueinheit. Zur Rotation der Spritzpistole ist ein stationäres Antriebsmittel, nämlich ein Antriebsmotor vorgesehen. Die Spritzpistolenhalterung ist an einer weiteren Vorrichtung angeordnet, um die Spritzpistolenhalterung in Axialrichtung zu positionieren. Die Drahtvorschubeinrichtung weist zwei Drahtvorratsrollen auf, wobei die Drahtvorratsrollen drehbar auf Achsen am Grundkörper angeordnet sind. Auf die Drahtvorratsrollen sind Spritzdrähte aufgerollt. Die Spritzpistole weist an einem Ende einen Düsenkopf auf. Der Düsenkopf ist dabei derart gekröpft ausgebildet, so dass eine Auslassöffnung im Wesentlichen in Radialrichtung gerichtet ist. Die Spritzdrähte treten aus dem Düsenkopf in einen Abschmelzbereich ein. Die Auslassöffnung steht mit Gaskanälen in Verbindung, die an Drehdurchführungen enden. Die Drehdurchführungen sind am Umfang des Grundkörpers angeordnet. Zur Stromversorgung der Spritzdrähte sind am Umfang des Grundkörpers Schleifringe befestigt, wobei im Inneren des Grundkörpers zwischen den Schleifringen und den Spritzdrähten Verbindungen bestehen. Bei Vorschub der Spritzdrähte in den Abschmelzbereich entsteht zwischen den sich nähernden Drähten ein Lichtbogen. Die Enden der Spritzdrähte werden im Lichtbogen abgeschmolzen. Die abgeschmolzenen Metallpartikel werden mittels des Gasstroms auf die vorbereitete Innenumfangsfläche einer Bohrung geschleudert. Dadurch, dass der Grundkörper mit der Beschichtungseinrichtung und der Drahtvorschubeinrichtung rotiert wird und gleichzeitig in Axialrichtung eine Bewegung in die Bohrung hinein ausgeführt wird, wird vom Spritzstrahl die gesamte Innenumfangsfläche der Bohrung abgedeckt. Diese Beschichtungsvorrichtung hat den Nachteil, dass nur Bohrungen mit einem kleinen Durchmesser beschichtet werden können. Die Beschichtungsvorrichtung ist nicht zur Beschichtung von Werkstücken mit einem großen Innendurchmesser geeignet. Die Beschichtungsvorrichtung ist ferner unhandlich.From the DE 102 04 251 A1 is a coating device for thermal coating, namely for arc wire spraying of holes known. The coating device has a coating device and a wire feed device. The coating device has a spray gun in the form of a hollow cylindrical base body. The main body also forms part of the wire feed device. The spray gun is rotatably mounted on a spray gun mount. The wire feed device and the spray gun device form a rigid, rotatable structural unit. For the rotation of the spray gun, a stationary drive means, namely a drive motor is provided. The spray gun mount is disposed on another device to position the spray gun mount in the axial direction. The wire feed device has two wire supply rolls, wherein the wire supply rolls are rotatably arranged on axes on the base body. On the wire supply rolls spray wires are rolled up. The Spray gun has a nozzle head at one end. The nozzle head is designed so cranked, so that an outlet opening is directed substantially in the radial direction. The spray wires enter from the nozzle head in a Abschmelzbereich. The outlet port communicates with gas ducts that terminate at rotary unions. The rotary unions are arranged on the circumference of the base body. To power the spray wires slip rings are attached to the circumference of the base body, wherein exist in the interior of the body between the slip rings and the spray wires connections. When advancing the spray wires in the Abschmelzbereich arises between the approaching wires an arc. The ends of the spray wires are melted in the arc. The molten metal particles are thrown by the gas flow on the prepared inner peripheral surface of a hole. Characterized in that the base body is rotated with the coating device and the wire feed device and at the same time a movement into the bore is carried out in the axial direction, the entire inner peripheral surface of the bore is covered by the spray jet. This coating device has the disadvantage that only holes with a small diameter can be coated. The coating device is not suitable for coating workpieces with a large inner diameter. The coating device is also unwieldy.

Aus der gattungsbildenden DE 198 41 617 A1 ist eine Beschichtungsvorrichtung zum thermischen Beschichten mittels Lichtbogendrahtspritzens von Innenwänden von Hohlkörpern bekannt. Es ist eine Beschichtungseinrichtung und eine Materialvorschubeinrichtung vorgesehen. Die Beschichtungseinrichtung weist eine Spritzpistole in Form eines Brennerschafts auf. Der Brennerschaft weist an seinem einen Ende einen Innenbrenner mit einem Brennerkopf auf. An dem anderen Ende ist starr eine Materialnachschubeinrichtung mit zwei Drahthaspeln befestigt. Der auf den Drahthaspeln aufgewickelte Spritzdraht wird entsprechend dem Verbrauch dem Brennerschaft zugeführt. Der Innenbrenner ist in den Brennerschaft austauschbar eingesteckt. Am Brennerkopf werden zwei Spritzdrähte zusammengeführt, wobei zwischen den beiden Spritzdrähten ein Lichtbogen zündbar ist. Der Brennerkopf weist ferner eine Druckluftdüse auf, die radial zur Längsachse des Brennerschafts gerichtet ist.From the generic DE 198 41 617 A1 For example, a coating apparatus for thermal coating by means of arc wire spraying of inner walls of hollow bodies is known. There is provided a coating device and a material feed device. The coating device has a spray gun in the form of a burner shaft. The burner shaft has at its one end an internal burner with a burner head. At the other end a material supply device is rigidly attached with two wire reels. The wound on the wire reels sprayer is fed according to the consumption of the burner shaft. The internal burner is inserted interchangeably in the burner shaft. Two spray wires are brought together at the burner head, whereby an arc can be ignited between the two spray wires. The burner head further comprises a compressed air nozzle which is directed radially to the longitudinal axis of the burner shaft.

Die Beschichtungseinrichtung ist an einer Spritzpistolenhalterung in Form eines Halteblocks drehbar gelagert. Der Antrieb des Brennerschafts erfolgt mittels eines in den Halteblock integrierten Motors, wobei der Motor einen Riemen antreibt. Der Halteblock ist an einem Roboterarm anordbar. Der endlose Riemen ist um den Brennerschaft geschlungen. Der Brennerkopf ist austauschbar, um die Beschichtungsvorrichtung an Werkstücke mit unterschiedlichen Bohrungsdurchmessern anzupassen. Es sind dabei zum einen Werkstücke in Form eines Nutzfahrzeug-Pleuels oder Zylinderbohrungen von PKWs mit einem Durchmesser von 75 bis 100 mm beschichtbar. Zum anderen können Werkstücke mit einem Bohrungsdurchmesser von 45 bis 75 mm beschichtet werden, wie zum Beispiel Nutzfahrzeug-Synchronringe und PKW-Pleuel.The coating device is rotatably mounted on a spray gun holder in the form of a holding block. The drive of the burner shaft by means of an integrated motor in the holding block, the motor drives a belt. The holding block can be arranged on a robot arm. The endless belt is wrapped around the burner shaft. The burner head is replaceable to adapt the coating apparatus to workpieces having different bore diameters. There are on the one hand workpieces in the form of a commercial vehicle connecting rod or cylinder bores of cars with a diameter of 75 to 100 mm coatable. On the other hand, workpieces with a bore diameter of 45 to 75 mm can be coated, such as commercial vehicle synchronizer rings and car connecting rods.

Diese gattungsbildende Beschichtungsvorrichtung ist noch nicht optimal ausgebildet. Um Bohrungen mit unterschiedlichen Durchmessern beschichten zu können, muss der Brennerkopf getauscht werden. Es sind dabei lediglich Werkstücke mit Bohrungen beschichtbar, wenn der Bohrungsdurchmesser 100 mm oder weniger beträgt. Es ist ein Roboterarm notwendig, um die Beschichtungsvorrichtung axial innerhalb der Bohrung zu bewegen. Hierdurch ist die Beschichtungsvorrichtung zwar stationär einsetzbar, aber die Beschichtungsvorrichtung ist insbesondere nicht gut transportierbar und damit mobil einsetzbar. Dies ist aufwendig, wenn insbesondere nur einzelne größere Werkstücke beschichtet werden sollen. Die Werkstücke müssen daher ausgebaut werden und zu der Beschichtungsvorrichtung transportiert werden. Werkstücke mit einem großen Durchmesser, bspw. einem Durchmesser von 150 mm bis 1500 mm sind häufig nur umständlich ausbaubar und schwer transportierbar. Lagersitze von Windkraftanlagen können bspw. mit den bestehenden Beschichtungsvorrichtungen nicht im montierten Zustand an der Windkraftanlage beschichtet werden.This generic coating device is not yet optimally formed. In order to coat holes with different diameters, the burner head must be exchanged. There are only workpieces with holes coated, if the bore diameter is 100 mm or less. A robotic arm is necessary to move the coater axially within the bore. Although this makes it possible to use the coating apparatus in a stationary manner, the coating apparatus is in particular not easy to transport and thus can be used for mobile use. This is expensive, especially if only single larger workpieces to be coated. The workpieces must therefore be removed and transported to the coating device. Workpieces with a large diameter, for example. A diameter of 150 mm to 1500 mm are often only cumbersome to remove and difficult to transport. Bearing seats of wind turbines can not be coated, for example, with the existing coating devices in the mounted state on the wind turbine.

Aus der DE 38 00 448 A1 ist ein Verfahren zur Durchlaufbeschichtung von Werkstücken, nämlich von Metall-Dosenkörpern, mit einer Plastbeschichtungsanlage bekannt. Die Dosenkörper werden zunächst an einer Schweißanlage geschweißt. Anschließend an die Schweißanlage ist eine Pulverplastbeschichtungsanordnung endständig an einem Schweißarm befestigt. Die Dosenkörper werden. Die Pulverplastbeschichtungsanordnung weist mehrere Düsenanordnungen auf, wobei Pulverplastzuführleitungen vorgesehen sind und durch die Pulverplastzuführleitungen ein Kunststoffpulver ausgegeben wird. Eine beim Schweißen entstehende Längsschweißnaht wird durch den Plaststrahl beschichtet beim Durchlauf des Dosenkörpers beschichtet. Ein Abstand L zwischen dem Schweißpunkt P und dem Auftreffbereich des Plaststrahles kann verändert werden, indem die Düsenanordnung linear verschoben und geschwenkt werden. Beim Beschichten wird nicht die Spritzpistole nicht bewegt, sondern die Werkstücke, nämlich die Dosenkörper werden über den Schweißarm bewegt.From the DE 38 00 448 A1 is a method for continuous coating of workpieces, namely metal can bodies, known with a plastic coating plant. The can bodies are first welded to a welding machine. Subsequent to the welding system, a powder plastic coating arrangement is attached terminally to a welding arm. The can body become. The powder plastic coating arrangement has a plurality of nozzle assemblies, wherein powder plastic supply lines are provided and a plastic powder is discharged through the powder plastic supply lines. A longitudinal weld formed during welding is coated by the plastic jet during the passage of the can body. A distance L between the welding point P and the impact area of the plastic jet can be changed by linearly displacing and pivoting the nozzle assembly. During coating, the spray gun is not moved, but the workpieces, namely the can bodies are moved over the welding arm.

Aus der US 4,065, 059 A ist eine Spritzvorrichtung zum Reparieren der Wände eines Koksofens bekannt. Diese Spritzvorrichtung weist ein Grundgestell und einen Schlitten auf, wobei das Grundgestell ortsfest relativ zum Koksofen, wobei der Schlitten an einer Führungsschiene verfahrbar ist, um mit einem Sichtrohr das Innere des Koksofens zu erreichen. Das Sichtrohr ist nach oben und unten schwenkbar am Schlitten angeordnet, um Reperaturstellen in unterschiedlicher Höhe im Koksofen erreichen zu können. Das Sichtrohr umfasst eine Materialzuführungsleitung, wobei die Materialzuführungsleitung radial seitlich in eine Austrittsdüse mündet. Das Sichtrohr ist um seine Längsachse rotierbar und weist an seinem freien Ende seitlich ein Fenster auf. Innerhalb des Sichtrohres ist ein Spiegel vor dem Fenster angeordnet, um entsprechend die Wände des Koksofens durch das Sichtrohr begutachten zu können. Die Austrittsdüse ist dabei endseitig des Fensters angeordnet. Die Spritzvorrichtung ist dabei nicht dazu ausgelegt, die gesamte Innenfläche des Koksofens durch Rotation und axiales Verschieben zu Beschichten, sondern lediglich einzelne zu reparierende Stellen. Da das Sichtrohr nur um seine Längsachse rotierbar ist, ist die radiale Position der der Austrittsdüse zur Rotationsachse durch den Rohrdurchmesser vorgegeben.From the US 4,065,059 A is a spray device for repairing the walls of a coke oven known. This spray device comprises a base frame and a carriage, wherein the base frame stationary relative to the coke oven, wherein the carriage is movable on a guide rail to reach with a sight tube, the interior of the coke oven. The sight tube is pivotally mounted up and down on the carriage to reach repair points at different heights in the coke oven can. The sight tube comprises a material supply line, wherein the material supply line opens radially laterally into an outlet nozzle. The sight tube is rotatable about its longitudinal axis and has at its free end laterally a window. Within the sight tube, a mirror is arranged in front of the window in order to be able to examine the walls of the coke oven through the sight tube accordingly. The outlet nozzle is arranged at the end of the window. The spray device is not designed to coat the entire inner surface of the coke oven by rotation and axial displacement, but only individual points to be repaired. Since the sight tube is rotatable only about its longitudinal axis, the radial position of the outlet nozzle is predetermined to the axis of rotation by the tube diameter.

Der Erfindung liegt daher die Aufgabe zugrunde, die gattungsbildende Beschichtungsvorrichtung derart auszugestalten und weiterzubilden, so dass hohle Werkstücke mit unterschiedlichem Innendurchmesser beschichtbar sind.The invention is therefore based on the object to design the generic coating device such and further, so that hollow workpieces with different inner diameter can be coated.

Diese der Erfindung zugrunde liegende Aufgabe nun durch gelöst, dass die Spritzpistolenhalterung verstellbar ist, wobei die Spritzpistolenhalterung einen schwenkbaren Arm aufweist, wobei die Spritzpistole an dem Arm angeordnet ist, wobei die radiale Positionierung der Spritzpistole zur Achse durch Schwenken des Arms einstellbar ist, wobei die Spritzpistolenhalterung ein Grundgestell und einen Schlitten aufweist, wobei das Grundgestell ortsfest relativ zum Werkstück anordbar ist, wobei das Grundgestell eine Führungsschiene aufweist, wobei der Schlitten an der Führungsschiene verfahrbar angeordnet ist. Dies hat den Vorteil, dass Werkstücke mit unterschiedlich großen Durchmessern beschichtet werden können. Der radiale Verstellweg der Spritzpistolenhalterung beträgt insbesondere mehr als 100 mm, vorzugsweise mehr als 200 mm, weiter vorzugsweise mehr als 300 mm. Die Beschichtungsvorrichtung kann dadurch individuell an unterschiedliche Werkstücke eingestellt und angepasst werden. Insbesondere ist die Beschichtungsvorrichtung mobil einsetzbar, so dass die Werkstücke - wie bspw. Lagersitze von Windkraftanlagen - nicht ausgebaut werden müssen, sondern eine Beschichtung vor Ort beim Kunden erfolgen kann. Der Anwendungsbereich der Beschichtungsvorrichtung ist erweitert.This object of the invention is based solved by that the spray gun holder is adjustable, the spray gun holder having a pivotable arm, wherein the spray gun is disposed on the arm, wherein the radial positioning of the spray gun is adjustable to the axis by pivoting the arm, wherein the Spray gun holder having a base frame and a carriage, wherein the base frame is stationary relative to the workpiece can be arranged, wherein the base frame has a guide rail, wherein the carriage is arranged to be movable on the guide rail. This has the advantage that workpieces with different diameters can be coated. The radial displacement of the spray gun holder is in particular more than 100 mm, preferably more than 200 mm, more preferably more than 300 mm. The coating device can be adjusted and adapted individually to different workpieces. In particular, the coating apparatus is mobile, so that the workpieces - such as. Bearing seats of wind turbines - do not need to be removed, but a coating can be done on site at the customer. The scope of application of the coating device is expanded.

Die Spritzpistolenhalterung weist einen schwenkbaren Arm auf, wobei die Spritzpistole an dem Arm angeordnet ist. Der Arm mit der Spritzpistole schwenkbar. Die radiale Positionierung der Spritzpistole ist durch Schwenken des Arms einstellbar. Die Winkellage der Spritzpistole relativ zur Innenumfangsfläche ist vorzugsweise einstellbar. Vor dem Beschichten wird die Spritzpistolenhalterung zentriert, so dass mit der Spritzpistole eine Rotation um eine (Zentrums-)Achse ausführbar ist. Diese Zentrumsachse entspricht durch die Zentrierung der Symmetrieachse des Werkstücks. Die radiale Positionierung der Spritzpistole relativ zur Zentrumsachse erfolgt durch Schwenken des Arms. Bei der Rotation führt die Spritzpistole eine Rotationsbewegung mit dem eingestellten radialen Abstand zur Zentrumsachse aus.The spray gun mount has a pivotable arm with the spray gun disposed on the arm. The arm can be swiveled with the spray gun. The radial positioning of the spray gun is adjustable by pivoting the arm. The angular position of the spray gun relative to the inner peripheral surface is preferably adjustable. Before coating, the spray gun holder is centered so that a rotation about a (center) axis can be carried out with the spray gun. This center axis corresponds to the centering of the axis of symmetry of the workpiece. The radial positioning of the spray gun relative to the center axis is done by pivoting the arm. During rotation, the spray gun performs a rotational movement with the set radial distance to the center axis.

Der Arm kann mindestens zwei Armteile und mindestens zwei Gelenke aufweisen, wobei die Armteile über mindestens eines der Gelenke miteinander verbunden sind und über mindestens ein weiteres Gelenk mit der Armhalterung verbunden sind. Die radiale Positionierung und die Winkellage der Spritzpistole sind durch Schwenken der Armteile einstellbar. Der Arm kann alternativ als Parallel-Arm ausgebildet sein, wobei die Winkellage der Spritzpistole beim Schwenken nicht verändert wird.The arm may have at least two arm parts and at least two joints, wherein the arm parts are connected to each other via at least one of the joints and are connected via at least one other joint with the arm holder. The radial positioning and the angular position of the spray gun are adjustable by pivoting the arm parts. The arm may alternatively be formed as a parallel arm, wherein the angular position of the spray gun is not changed during pivoting.

Die Spritzpistole ist beim Beschichten axial verfahrbar und/oder rotierbar. Der Antrieb für den axialen Vorschub und/oder die Rotation kann elektrisch, insbesondere elektromotorisch oder pneumatisch erfolgen. Vorzugsweise wird die Beschichtung durch Rotation der Spritzpistole aufgetragen. Je nach Tiefe des Werkstückes kann die Spritzpistole dabei axial verfahren werden, so dass die gesamte Innenumfangsfläche beschichtet wird. Die Spritzpistole kann beim Beschichten eine spiralförmige Bewegung ausführen.The spray gun is axially movable during coating and / or rotatable. The drive for the axial feed and / or the rotation can be done electrically, in particular by electric motor or pneumatically. Preferably, the coating is applied by rotation of the spray gun. Depending on the depth of the workpiece, the spray gun can be moved axially, so that the entire inner peripheral surface is coated. The spray gun can perform a helical movement during coating.

Es ist denkbar, dass die Spritzpistole alternativ einen getakteten Vorschub in die Bohrung ausführt, d.h. in die Bohrung eintaucht und wieder herausgezogen wird und sodann um einen Winkelschritt gedreht wird und danach wieder eintaucht. Dies könnte solange wiederholt werden, bis die gesamte Innenumfangsfläche beschichtet ist.It is conceivable that the spray gun alternatively performs a clocked feed into the bore, i. is dipped into the hole and pulled out again and then rotated by an angular step and then immersed again. This could be repeated until the entire inner circumferential surface is coated.

Es ist denkbar, dass die Spritzpistole mit einem Verlängerungsteil verlängerbar ist. Das Verlängerungsteil kann eine Länge von bspw. 300 bis 1000 mm aufweisen. Wenn nun die Spritzpistole mit dem entsprechenden Verlängerungsteil ausgestattet ist, ermöglicht dies ein besonders tiefes Eindringen in Werkstücke mit einem kleinen Innendurchmesser. Das Verlängerungsteil kann eine Austrittsöffnung, insbesondere im Winkel von in etwa 70° zu seiner Längsrichtung aufweisen, so dass das Verlängerungsteil zum Beschichten axial in den Hohlraum des Werkstücks eingeführt werden kann.It is conceivable that the spray gun is extendable with an extension part. The extension part may have a length of, for example, 300 to 1000 mm. Now, if the spray gun is equipped with the corresponding extension part, this allows a particularly deep penetration into workpieces with a small inner diameter. The extension part can have an outlet opening, in particular at an angle of approximately 70 ° to its longitudinal direction, so that the extension part can be inserted axially into the cavity of the workpiece for coating.

Die Spritzpistolenhalterung weist ein Grundgestell und einen Schlitten auf, wobei das Grundgestell ortsfest relativ zum Werkstück anordbar ist. Das Grundgestell ist relativ zum Werkstück positionierbar. Vorzugsweise ist das Grundgestell am Werkstück abgestützt und/oder mit dem Werkstück lösbar verbunden. Das Grundgestell weist eine sich insbesondere in Axialrichtung erstreckende Führungsschiene auf. Der Schlitten ist an der Führungsschiene insbesondere horizontal verfahrbar. Der Arm ist an dem Schlitten rotierbar gelagert.The spray gun holder has a base frame and a carriage, wherein the base frame is stationary relative to the workpiece can be arranged. The base frame can be positioned relative to the workpiece. Preferably, the base frame is supported on the workpiece and / or releasably connected to the workpiece. The base frame has a guide rail extending in particular in the axial direction. The carriage is in particular movable horizontally on the guide rail. The arm is rotatably mounted on the carriage.

In besonders bevorzugter Ausgestaltung ist die Materialvorschubeinrichtung über ein flexibles Versorgungsrohr mit der Beschichtungseinrichtung verbunden, wobei innerhalb des Versorgungsrohres der Beschichtungswerkstoff förderbar ist. Dies hat den Vorteil, dass die Beschichtungsvorrichtung insbesondere mobil einsetzbar ist. Die Beschichtungseinrichtung und die Materialvorschubeinrichtung sind winklig zueinander anordbar. Dies ist vorteilhaft, da hierdurch die Beschichtungsvorrichtung auch in beengten Räumlichkeiten entsprechend flexibel aufgebaut werden kann. Beispielsweise lassen sich hierdurch Großgetriebe bspw. Lagersitze von Windkraftanlagen vor Ort im eingebauten Zustand beschichten. Das Versorgungsrohr kann als Wellrohr oder als flexibler Schlauch ausgebildet sein. Alternativ sind die Materialvorschubeinrichtung Beschichtungseinrichtung starr miteinander verbunden.In a particularly preferred embodiment, the material feed device is connected via a flexible supply pipe to the coating device, wherein the coating material can be conveyed within the supply pipe. This has the advantage that the coating device can be used in particular mobile. The coating device and the material feed device can be arranged at an angle to one another. This is advantageous, since in this way the coating device can be flexibly constructed in confined spaces. For example, this allows large gearboxes, for example, bearing seats of wind turbines to be coated locally when installed. The supply pipe may be formed as a corrugated pipe or as a flexible hose. Alternatively, the material feed device coating device are rigidly interconnected.

Die Beschichtungsvorrichtung ist vorzugsweise als Lichtbogendrahtspritzvorrichtung ausgebildet; die Materialvorschubeinrichtung weist ein entsprechendes Drahtmagazin auf. Die Materialvorschubeinrichtung dient dabei zum Fördern mindestens eines Spritzdrahtes. Die Materialschubvorrichtung weist vzw. einen Förderantrieb bspw. motorisch angetriebene Drahtförderrollen auf. Es ist denkbar, dass die Beschichtungseinrichtung einen zusätzlichen Förderantrieb zum Fördern des Spritzdrahtes aufweist. Der Förderantrieb der Materialvorschubeinrichtung wirkt im Wesentlichen schiebend und der Förderantrieb der Beschichtungseinrichtung wirkt im Wesentlichen ziehend, um einen Drahtstau wirksam zu vermeiden.The coating device is preferably designed as an arc wire spraying device; the material feed device has a corresponding wire magazine. The material feed device serves to convey at least one spray wire. The material thruster has vzw. a conveyor drive, for example, motor-driven wire feed rollers. It is conceivable that the coating device has an additional conveyor drive for conveying the spray wire. The conveyor drive of the material feed device acts essentially pushing and the conveyor drive of the coating device acts essentially pulling to effectively avoid a wire jam.

Die Materialvorschubeinrichtung weist eine Führungsschiene und einen Magazinschlitten auf, wobei der Magazinschlitten an der Führungsschiene verschiebbar ist. An dem Magazinschlitten ist das Drahtmagazin drehbar gelagert. Das Drahtmagazin ist vorzugsweise mittels eines Antriebsmittels drehbar. Das Antriebsmittel kann als Motor, insbesondere als Elektromotor ausgebildet sein oder pneumatisch oder hydraulisch wirken. Das Drahtmagazin weist zwei Drahtvorratsspulen auf. Das Drahtmagazin ist vzw. mit dem flexiblen Versorgungsrohr verbunden. Hierdurch ist der Vorschub der Spritzpistole durch Verschieben des Drahtmagazins ausgleichbar. Innerhalb des Versorgungsrohres erstrecken sich vorzugsweise zwei Spritzdrähte, eine Gaszufuhr, und ggf. elektrische Leitungen. Die Spritzdrähte werden je nach Verbrauch nachgeschoben. Die Materialvorschubeinrichtung weist vorzugsweise mindestens eine Drehdurchführung auf, wobei über die mindestens eine Drehdurchführung Gas und/oder elektrischer Strom zuführbar ist. Eine entsprechende Gasleitung erstreckt sich vorzugsweise durch das Versorgungsrohr. Die Spritzdrähte sind über elektrische Leitungen mit den entsprechenden Kontakten der Drehdurchführung verbunden.The material feed device has a guide rail and a magazine carriage, wherein the magazine carriage is displaceable on the guide rail. On the magazine slide the wire magazine is rotatably mounted. The wire magazine is preferably rotatable by means of a drive means. The drive means may be designed as a motor, in particular as an electric motor or act pneumatically or hydraulically. The wire magazine has two wire supply spools. The wire magazine is vzw. connected to the flexible supply pipe. As a result, the feed of the spray gun by moving the wire magazine compensated. Within the supply pipe preferably two spray wires, a gas supply, and possibly electrical lines extend. The spray wires are pushed back according to consumption. The material feed device preferably has at least one rotary feedthrough, wherein gas and / or electrical current can be supplied via the at least one rotary feedthrough. A corresponding gas line preferably extends through the supply pipe. The spray wires are connected via electrical lines to the corresponding contacts of the rotary feedthrough.

Es ist denkbar, dass die Spritzpistole gegen ein mechanisches Bearbeitungsgerät austauschbar ist, wobei mit dem mechanischen Bearbeitungsgerät eine mechanische Bearbeitung der Innenumfangsfläche durchführbar ist. Dies hat den Vorteil, dass eine Zentrierung nur einmal vorgenommen werden muss. Es ist sichergestellt, dass sowohl beim Beschichten als auch bei der mechanischen Bearbeitung die Spritzpistole und das mechanische Bearbeitungsgerät relativ zur gleichen Zentrumsachse rotiert und/oder axial verfahren werden.It is conceivable that the spray gun is interchangeable with a mechanical processing device, with the mechanical processing device, a mechanical processing of the inner peripheral surface is feasible. This has the advantage that a centering only needs to be done once. It is ensured that the spray gun and the mechanical processing device are rotated and / or moved axially relative to the same center axis both during coating and during mechanical processing.

Die eingangs genannten Nachteile sind daher vermieden und entsprechende Vorteile sind erzielt.The aforementioned disadvantages are therefore avoided and corresponding advantages are achieved.

Es gibt nun eine Vielzahl von Möglichkeiten, die erfindungsgemäße Beschichtungsvorrichtung auszugestalten und weiterzubilden.
