Bei bekannten Lackieranlagen für Fahrzeugkarosserien in der Großserienproduktion werden die zu lackierenden Fahrzeugkarosserien taktweise oder kontinuierlich längs einer Vorschubstrecke gefördert, an der Reinigungseinrichtungen, Lackiereinrichtungen für Füller, Kontrollstationen für die Füllerlackierung, Durchlauftrockner für die Trocknung der Füllerlackierung, weitere Reinigungseinrichtungen, Lackiereinrichtungen für Decklack, Kontrollstationen für die Decklackierung und Durchlauftrockner für die Decklackierung sequentiell aufeinanderfolgen. Dabei ist die in jeder dieser aufeinanderfolgenden Stationen zur Verfügung stehende Bearbeitungszeit durch die kontinuierliche Fördergeschwindigkeit bzw. durch die Taktzeit bei getakteter Förderung für alle Fahrzeugkarosserien in derselben Weise vorgegeben. Die kontinuierliche Fördergeschwindigkeit bzw. die bei taktweiser Förderung vorgegebene Taktzeit muss sich daher nach der Bearbeitungszeit richten, welche in der bearbeitungsintensivsten Bearbeitungsstation für den bearbeitungsintensivsten Fahrzeugkarosserietyp benötigt wird. Dies kann dazu führen, dass die kontinuierliche Fördergeschwindigkeit auf einen ineffizient niedrigen bzw. die Taktzeit auf einen ineffizient hohen Wert eingestellt werden müssen.In known paint shops for vehicle bodies in mass production, the vehicle bodies to be painted are cyclically or continuously conveyed along a feed line, at the cleaning facilities, painting facilities for fillers, control stations for the surfacer coat, continuous dryer for drying the surfacer coat, other cleaning equipment, painting equipment for topcoat, control stations for sequentially follow the topcoat and top coat dryers. The processing time available in each of these successive stations is predetermined in the same way by the continuous conveying speed or by the cycle time with clocked conveying for all vehicle bodies. The continuous conveying speed or the cycle time specified in the case of cyclical conveying must therefore be based on the processing time which is required in the machining-intensive processing station for the machining-intensive vehicle body type. This may mean that the continuous conveying speed must be set to an inefficiently low or the cycle time to an inefficiently high value.

Aus der EP 0 108 289 B1 ist eine Vorrichtung zum Lackieren von Fahrzeugkarosserien mit einer eine Anzahl von Karosserien hintereinander längs einer Vorschubstrecke bewegenden Transporteinrichtung und mit längs der Vorschubstrecke stationär angeordneten Bearbeitungsgeräten, welche die vorbeibewegten Karosserien bearbeiten, bekannt, wobei seitlich der Vorschubstrecke mindestens zwei Stellplätze für die Karosserien vorgesehen sind, jedem Stellplatz eine Verschiebeeinrichtung zugeordnet ist, welche eine Karosserie von der Vorschubstrecke quer zu dieser auf den Stellplatz und nach einer Verweildauer auf diesem wieder quer zur Vorschubstrecke auf diese zurücktransportiert, wobei ferner auf dem Stellplatz Bearbeitungsgeräte angeordnet sind, welche die stationär auf dem Stellplatz verweilende Karosserie bearbeiten, und wobei die Karosserie auf dem Stellplatz die Vorschubstrecke freigibt, so dass längs der Vorschubstrecke Karosserien an dem Stellplatz vorbeitransportiert werden können. Diese bekannte Vorrichtung zum Lackieren von Kraftfahrzeugkarosserien erlaubt es, einzelne Fahrzeugkarosserien für einzelne, besonders komplizierte und aufwendige Bearbeitungsschritte, insbesondere für die Innenraumlackierung von Kraftfahrzeugkarosserien, aus der Vorschubstrecke auszuschleusen und nach der Durchführung des besonders komplizierten Bearbeitungsschrittes wieder in die Vorschubstrecke einzuschleusen. Hierbei wird jedoch nur ein spezieller Teil der Lackiervorgänge auf dem Stellplatz seitlich neben der Vorschubstrecke ausgeführt, während alle übrigen Lackiervorgänge mittels der längs der Vorschubstrecke angeordneten Bearbeitungsgeräte durchgeführt werden. Das Problem, dass die Fördergeschwindigkeit bzw. die Taktzeit der Förderung längs der Vorschubstrecke an den bearbeitungsintensivsten Fahrzeugkarosserietyp angepasst werden müssen, bleibt also auch bei dieser bekannten Vorrichtung zur Lackierung von Kraftfahrzeugkarosserien bestehen.From the EP 0 108 289 B1 is a device for painting vehicle bodies with a number of bodies in a row along one Feed line moving transport device and along the feed line stationary processing equipment, which edit the passing bodies, known, wherein the feed path at least two parking spaces are provided for the bodies, each pitch is assigned a displacement device which a body of the feed path transverse to this the pitch and after a dwell time on this back transversely to the feed distance transported back to this, further being arranged on the pitch processing equipment, which edit the stationary on the pitch lingering body, and the body on the pitch releases the feed path, so that along the Feed line bodies can be transported past the parking space. This known device for painting motor vehicle bodies makes it possible to eject individual vehicle bodies for individual, particularly complicated and complex processing steps, in particular for the interior painting of motor vehicle bodies, from the feed path and to feed them back into the feed path after the particularly complicated processing step has been carried out. In this case, however, only a special part of the painting processes on the parking space is carried out laterally next to the feed path, while all other painting operations are carried out by means of the processing devices arranged along the feed path. The problem that the conveying speed or the cycle time of the promotion must be adjusted along the feed path to the most processing-intensive vehicle body type, so also in this known device for painting motor vehicle bodies.

Der Artikel von Siegfried Klemm: "Vollautomatische Füller-Applikation mit Lackierrobotern", JOT Journal für Oberflächentechnik, [Online] Nr. 3/2002, März 2003, Seiten 50-53 , XP002386146 offenbart eine Lackieranlage für Fahrzeugkarosserien in der Großserienproduktion, bei der Fahrzeugkarosserien in vier aufeinanderfolgenden Lackierzonen zunächst außen und dann innen mit einem Füller lackiert werden, wobei der Lack im Taktbetrieb appliziert werden kann.The article of Siegfried Klemm: "Fully Automatic Filler Application with Painting Robots", JOT Journal for Surface Technology, [Online] No. 3/2002, March 2003, pages 50-53 , XP002386146 discloses a painting system for vehicle bodies in mass production, in which vehicle bodies are painted in four successive painting zones first outside and then inside with a filler, the paint can be applied in clock mode.

Die CH 424 553 A offenbart eine Anlage zum Spritzlackieren und Trocknen von Kraftfahrzeugen bei Reparaturlackierungen, bei der die Kraftfahrzeuge in einem Spritzraum mittels auf Schienen seitlich hin und her verschiebbarer Förderbänder je nach Lackierumfang entweder in die linke Spur oder die rechte Spur sich anschließender Trockenräume eingebracht werden können.The CH 424 553 A discloses a system for spray painting and drying of motor vehicles in refinish, in which the motor vehicles can be introduced in a spray room by means of rails laterally displaceable conveyor belts depending on the Lackierumfang either in the left lane or the right track subsequent drying spaces.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Lackieranlage für Fahrzeugkarosserien in der Großserienproduktion der eingangs genannten Art zu schaffen, welche auch dann effizient arbeitet, wenn der Lackieranlage in gemischter Folge Fahrzeugkarosserien von verschiedenen Fahrzeugkarosserietypen zugeführt werden, welche deutlich unterschiedliche Bearbeitungszeiten für die Lackierung benötigen.The present invention has for its object to provide a paint shop for vehicle bodies in mass production of the type mentioned, which also works efficiently when the paint shop in mixed sequence vehicle bodies are supplied by different vehicle body types, which require significantly different processing times for painting.

Diese Aufgabe wird durch eine Lackieranlage gemäß Anspruch 1 gelöst.This object is achieved by a paint shop according to claim 1.

Der erfindungsgemäßen Lösung liegt somit das Konzept zugrunde, die komplette Innen- und Außenlackierung einer Fahrzeugkarosserie mit Füller, die komplette Innen- und Außenlackierung einer Fahrzeugkarosserie mit Decklack und/oder die komplette Innen- und Außenlackierung einer Fahrzeugkarosserie mit Decklack-Basislack in einem einzigen Arbeitsschritt in einer einzigen Lackierbox vollautomatisch durchzuführen, wobei die Verweilzeit jeder Fahrzeugkarosserie in der Lackierbox jeweils in Abhängigkeit von dem Fahrzeugkarosserietyp und von der Art des Lackiervorgangs (Füller, Decklack oder Decklack-Basislack) vorgegeben ist und sich somit von Fahrzeugkarosserietyp zu Fahrzeugkarosserietyp um einen beliebigen Faktor unterscheiden kann, ohne dass hierdurch die Effizienz der Lackieranlage beeinträchtigt wird.The solution according to the invention is thus based on the concept of the complete interior and exterior painting of a vehicle body with filler, the complete interior and exterior painting of a vehicle body with topcoat and / or the complete interior and exterior painting of a vehicle body with topcoat basecoat in a single step a single Lackierbox perform fully automatic, wherein the residence time of each vehicle body in the Lackierbox each depending on the vehicle body type and type of painting (filler, topcoat or topcoat basecoat) is predetermined and thus may differ from vehicle body type to vehicle body type by any factor without affecting the efficiency of the paint shop.

Dabei wird in der Regel eine kleine Fahrzeugkarosserie eine kurze Verweilzeit in der Lackierbox aufweisen, während eine größere Fahrzeugkarosserie eine längere Verweilzeit in der Lackierbox aufweisen wird.As a rule, a small vehicle body will have a short residence time in the paint booth, while a larger vehicle body will have a longer residence time in the paint booth.

Die in der Praxis notwendigen Unterschiede der Verweilzeiten (bei jeweils gleicher Lackiervorgangsart) können bis zu einem Faktor 2 betragen.The necessary differences in the residence times in practice (each with the same Lackiervorgangsart) can be up to a factor of 2.

Besonders große fahrzeugkarosserietypspezifische Unterschiede in den erforderlichen Verweilzeiten treten bei der Lackierung von Transporterfahrzeugen auf, welche - in Abhängigkeit vom jeweiligen Radstand - stark unterschiedliche Laderaumgrößen und somit deutliche Unterschiede in der Größe der jeweils zu lackierenden Fläche aufweisen.Particularly large vehicle body type-specific differences in the required residence times occur in the painting of van vehicles, which - depending on the wheelbase - have very different load compartment sizes and thus significant differences in the size of each surface to be painted.

Durch die Durchführung der kompletten Innen- und Außenlackierung einer Fahrzeugkarosserie in jeweils einer einzigen Lackierbox entfallen die Förderzeiten zwischen verschiedenen Lackierstationen einer Lackierlinie.By carrying out the complete interior and exterior painting of a vehicle body in each case in a single Lackierbox accounts for the delivery times between different painting a Lackierlinie.

Außerdem ist eine Vermessung des Standortes einer zu lackierenden Fahrzeugkarosserie nur einmal und nicht mehrfach, in mehreren aufeinanderfolgenden Lackierstationen für dieselbe Lackart, erforderlich.In addition, a survey of the location of a vehicle body to be painted is only once and not several times, in several successive Lackierstationen for the same Lackart required.

Besonders günstig ist es, wenn der Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack mindestens zwei Lackierboxen umfasst, welche individuell und flexibel, je nach dem gerade bestehenden Bedarf, mit Fahrzeugkarosserien von unterschiedlichen Fahrzeugkarosserietypen belegt werden können.It is particularly advantageous if the painting section for filler and / or topcoat and / or topcoat basecoat comprises at least two paint booths, which can be individually and flexibly, depending on the current needs, with vehicle bodies of different vehicle body types occupied.

Durch die Optimierung der Anzahl parallel zueinander betreibbarer Lackierboxen und durch Optimierung der Anzahl der Lackierautomaten in jeder Lackierbox kann die Effizienz der erfindungsgemäßen Lackieranlage im Vergleich zum klassischen Linienkonzept, bei welchem die Lackierautomaten längs einer von allen Fahrzeugkarosserien durchlaufenen Vorschubstrecke angeordnet sind, deutlich erhöht werden.By optimizing the number of paint booths that can be operated in parallel and by optimizing the number of paint sprayers in each paint booth, the efficiency of the paint shop according to the invention can be reduced compared to the classic line concept in which the paint booths are longitudinal one of all vehicle bodies traversed feed distance are arranged to be significantly increased.

Vorzugsweise ist vorgesehen, dass die Lackierung sämtlicher Fahrzeugkarosserien, welche dem Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack zugeführt werden, in einer Lackierbox durchgeführt wird, und dass kein Lackiervorgang mit Füller und/oder Decklack und/oder Decklack-Basislack außerhalb einer solchen Lackierbox, an einer klassischen Lackierlinie, durchgeführt wird.It is preferably provided that the painting of all vehicle bodies, which are supplied to the coating section for filler and / or topcoat and / or topcoat basecoat, is carried out in a Lackierbox, and that no painting process with filler and / or topcoat and / or topcoat basecoat outside of such a Lackierbox, on a classic paint line, is performed.

Ferner werden die Fahrzeugkarosserien vorzugsweise für die Lackierung innerhalb der Lackierbox stillgesetzt.Furthermore, the vehicle bodies are preferably stopped for painting within the Lackierbox.

Bei Verwendung mehrerer parallel geschalteter Lackierboxen ergibt sich der zusätzliche Vorteil, dass bei einer Reduzierung der Stückzahl der Fahrzeugkarosserien, welche pro Zeiteinheit in dem Lackierabschnitt zu lackieren sind, einzelne Lackierboxen stillgelegt werden können, wodurch der Energie- und Instandhaltungsaufwand deutlich reduziert wird, während eine solche zeitweise Stillegung von Lackierabschnitten beim klassischen Linienkonzept einer Lackieranlage nicht möglich ist.When using several parallel connected Lackierboxen there is the additional advantage that with a reduction in the number of vehicle bodies, which are to be painted per unit time in the painting, individual Lackierboxen can be shut down, whereby the energy and maintenance costs is significantly reduced, while such temporary shutdown of paint sections is not possible with the classic line concept of a paint shop.

Umgekehrt kann die Bearbeitungskapazität des Lackierabschnittes für eine Erhöhung der Stückzahl der Fahrzeugkarosserien, welche in dem Lackierabschnitt pro Zeiteinheit zu lackieren sind, durch den Anbau bzw. die Inbetriebnahme weiterer parallel geschalteter Lackierboxen in einfacher und flexibler Weise erweitert werden.Conversely, the processing capacity of the Lackierabschnittes for an increase in the number of vehicle bodies, which are to be painted in the Lackierabschnitt per unit time, be extended by the cultivation or commissioning of other parallel-connected Lackierboxen in a simple and flexible manner.

Dadurch, dass der Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack mehrere parallel zueinander betriebene, voneinander unabhängige Lackierboxen aufweist, ist auch im Falle von Störungen einzelner Lackierboxen eine hohe technische Verfügbarkeit des Lackierabschnitts als Ganzem gegeben.The fact that the painting section for filler and / or topcoat and / or topcoat basecoat has several parallel operated, independent paint booths, a high technical availability of Lackierabschnitts is given as a whole in the event of disturbances of individual Lackierboxen.

Bei einem Fahrzeugkarosserietypwechsel genügt es, die in einer einzigen Lackierbox vorhandenen Lackierautomaten, beispielsweise durch ein Teach-In-Verfahren, für den neuen Fahrzeugkarosserietyp neu zu programmieren und anschließend die in dieser einen Lackierbox neu erstellten Programme auf die entsprechenden Lackierautomaten der übrigen Lackierboxen zu übertragen. Dabei kann die erforderliche Neuprogrammierung in einer Lackierbox durchgeführt werden, während der normale Lackierbetrieb in den übrigen Lackierboxen ungestört weiterläuft. Beim klassischen Linienkonzept ist hingegen bei einem Fahrzeugkarosserietypwechsel und der hierfür erforderlichen Neuprogrammierung der Lackierautomaten stets die ganze Lackierlinie betroffen.In a vehicle body type change, it is sufficient to reprogram the existing in a single Lackierbox paint machines, for example, by a teach-in procedure for the new vehicle body type and then to transfer the newly created in this one Lackierbox programs on the corresponding coating machines of other Lackierboxen. In this case, the required reprogramming can be carried out in a Lackierbox, while the normal painting continues to run undisturbed in the other Lackierboxen. In the classic line concept, however, the entire paint line is always affected in a vehicle body type change and the requisite reprogramming of the painting machines.

Eine besonders effiziente Nutzung der Lackierkapazitäten in dem Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack wird erzielt, wenn in der mindestens einen Lackierbox dieses Lackierabschnitts sowohl eine vollautomatische Füller-Lackierung als auch eine vollautomatische Decklack-Lackierung und/oder eine vollautomatische Decklack-Basislackierung durchführbar ist. In diesem Fall kann die Lackierbox, je nach Bedarf, mit einer mit dem Füller zu lackierenden Fahrzeugkarosserie oder mit einer mit dem Decklack oder dem Decklack-Basislack zu lackierenden Fahrzeugkarosserie belegt werden, so dass jede frei werdende Lackierbox sofort mit der nächsten dem Lackierabschnitt zugeführten Fahrzeugkarosserie beschickt werden kann, unabhängig davon, ob diese Fahrzeugkarosserie bereits mit der Füllerlackierung versehen ist oder nicht.A particularly efficient use of the coating capacities in the coating section for filler and / or topcoat and / or topcoat basecoat is achieved if in the at least one painting this Lackierabschnitts both a fully automatic filler painting and a fully automatic topcoat paint and / or a fully automatic Topcoat basecoat is feasible. In this case, the Lackierbox, as required, are covered with a to be painted with the filler vehicle body or with the topcoat or topcoat base paint to be painted vehicle body, so that each vacant paint box immediately with the next supplied to the painting vehicle body can be charged, regardless of whether this vehicle body is already provided with the filler coat or not.

Die Verweilzeit in der mindestens einen Lackierbox ist vorzugsweise für jeden Fahrzeugkarosserietyp und für jeden Lackiervorgangstyp fest vorgegeben.The residence time in the at least one painting box is preferably fixed for each vehicle body type and for each type of painting operation.

Bei einer bevorzugten Ausgestaltung der Erfindung ist ferner vorgesehen, dass die Lackieranlage eine Karosserieverteileinrichtung umfasst, welcher in dem Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack lackierte Fahrzeugkarosserien zugeführt werden und von welcher Fahrzeugkarosserien wahlweise in einen von mindestens zwei verschiedenen Durchlauftrocknern abgegeben werden. Hierdurch ist es möglich, in demselben Lackierabschnitt die Lackierung der Fahrzeugkarosserien sowohl mit Füller als auch mit Decklack und/oder mit Decklack-Basislack durchzuführen und die so lackierten Fahrzeugkarosserien anschließend flexibel auf verschiedene Durchlauftrockner zu verteilen, welche jeweils für den Trocknungsvorgang einer bestimmten Lackierungsart optimal abgestimmt sind.In a preferred embodiment of the invention, it is further provided that the paint shop comprises a body distribution device, which are supplied in the painting section for filler and / or topcoat and / or topcoat basecoat painted vehicle bodies and delivered from which vehicle bodies either in one of at least two different continuous dryers become. This makes it possible to carry out the painting of the vehicle bodies both with filler and topcoat and / or topcoat basecoat in the same Lackierabschnitt and then distribute the vehicle bodies so flexibly on different continuous dryers, which optimally matched respectively for the drying process of a particular Lackierungsart are.

Besonders günstig ist, wenn die Fahrzeugkarosserien von der Karosserieverteileinrichtung wahlweise in einen von mindestens drei Durchlauftrocknern abgegeben werden.It is particularly advantageous if the vehicle bodies are delivered by the body distribution device either in one of at least three continuous driers.

Insbesondere kann vorgesehen sein, dass die Fahrzeugkarosserien von der Karosserieverteileinrichtung einem Füller-Durchlauftrockner zuführbar sind.In particular, it can be provided that the vehicle bodies can be fed from the body distribution device to a filler through-flow dryer.

Alternativ oder ergänzend hierzu kann vorgesehen sein, dass die Fahrzeugkarosserien von der Karosserieverteileinrichtung einem Decklack-Durchlauftrockner zuführbar sind.Alternatively or additionally, it can be provided that the vehicle bodies can be fed from the body distribution device to a top-coat continuous-flow dryer.

Alternativ oder ergänzend hierzu kann ferner vorgesehen sein, dass die Fahrzeugkarosserien von der Karosserieverteileinrichtung einem Decklack-Basislack-Zwischen-Durchlauftrockner zuführbar sind.As an alternative or in addition to this, it can further be provided that the vehicle bodies can be fed from the body distribution device to a topcoat-basecoat intermediate through-flow dryer.

Unter einem Decklack-Basislack ist dabei ein Lack zu verstehen, welcher nach dem Füllerauftrag als farbgebende Schicht aufgetragen wird.Under a topcoat basecoat is understood to mean a paint, which is applied after the filler application as a coloring layer.

Ein solcher Decklack-Basislack kann beispielsweise ein Metallic-Lack sein.Such a topcoat basecoat may for example be a metallic paint.

Unter einem Durchlauftrockner ist in dieser Beschreibung und in den beigefügten Ansprüchen ein Trockner zu verstehen, durch welchen die Fahrzeugkarosserien kontinuierlich oder taktweise hindurchgefördert werden, wobei sich jeweils mehrere Fahrzeugkarosserien gleichzeitig hintereinander in demselben Trockner befinden. Der Begriff Durchlauftrockner umfasst insbesondere auch sogenannte "A-Trockner" (also solche, die am Eingang und am Ausgang eine Aufzugsschleuse aufweisen).In this description and in the appended claims, a continuous-flow drier is to be understood as meaning a drier through which the vehicle bodies are conveyed continuously or intermittently, wherein in each case several vehicle bodies are located one after the other in the same drier. In particular, the term continuous dryer also includes so-called "A dryers" (ie those which have an elevator lock at the entrance and at the exit).

Bei der erfindungsgemäßen Lackieranlage können der Füller-Durchlauftrockner und der Decklack-Durchlauftrockner voneinander verschiedene, jeweils auf die Trocknung der Füllerlackierung bzw. der Decklackierung abgestimmte Durchlauftrockner sein.In the painting installation according to the invention, the continuous through-flow dryer and the topcoat continuous dryer can be different from one another, in each case matched to the drying of the surfacer or the topcoat continuous dryer.

Es ist aber auch ohne weiteres denkbar, dass der Füller-Durchlauftrockner und der Decklack-Durchlauftrockner miteinander identisch sind, d.h. dass die Fahrzeugkarosserien nach der Füllerlackierung denselben Durchlauftrockner durchlaufen wie nach der Decklackierung.However, it is also readily conceivable that the filler through-drier and top-coat continuous drier are identical to one another, i. that the vehicle bodies run through the same through-drier after the filler coat as after the top coat.

Ferner ist es von Vorteil, wenn die Lackieranlage eine stromaufwärts von der Karosserieverteileinrichtung angeordnete Kontrollstation umfasst. Eine solche, von den Fahrzeugkarosserien vor der Karosserieverteileinrichtung durchlaufene Kontrollstation kann dazu genutzt werden, nach allen Lackaufträgen, die an einer Fahrzeugkarosserie erfolgen, jeweils vor dem Trocknen eine Kontrolle der Lackierqualität durchzuführen, so dass nur eine gemeinsame Kontrollstation benötigt wird, um sowohl die Füllerlackierung als auch die Decklackierung, die Decklack-Basislackierung und die Klarlackierung zu kontrollieren, während im Gegensatz hierzu bei einer klassischen Linien-Lackieranlage je eine separate Kontrollstation für die Füllerlackierung, für die Decklackierung bzw. die Decklack-Basislackierung und für die Klarlackierung erforderlich ist.Furthermore, it is advantageous if the paint shop comprises a control station arranged upstream of the body distribution device. Such, From the vehicle bodies in front of the body distribution device passed control station can be used to perform after all paint jobs that take place on a vehicle body, each before drying a control of Lackierqualität, so that only a common control station is required to both the surfacer and the top coat to control the top coat basecoat and the clearcoat, whereas in contrast to a classic line painting plant, a separate control station for the surfacer coat, for the topcoat or the topcoat basecoat and for the clearcoat is required.

Bei einer bevorzugten Ausgestaltung der erfindungsgemäßen Lackieranlage ist vorgesehen, dass die Lackieranlage einen Klarlack-Lackierabschnitt umfasst, der mindestens eine Klarlackierbox umfasst, in welcher eine vollautomatische Innen- und Außenlackierung mit Klarlack von Fahrzeugkarosserien von mindestens zwei verschiedenen Fahrzeugkarosserietypen durchführbar ist. Durch die Umsetzung des Lackierboxen-Konzepts auch im Klarlack-Lackierabschnitt werden die Vorteile höherer Flexibilität und effizienterer Ausnutzung der Lackieranlage, welche vorstehend im Zusammenhang mit dem Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack beschrieben worden sind, auch in Bezug auf den Klarlack-Läckierabschnitt erreicht.In a preferred refinement of the painting installation according to the invention, it is provided that the painting installation comprises a clearcoat painting section which comprises at least one clearcoat box in which a fully automatic interior and exterior painting with clearcoat of vehicle bodies of at least two different vehicle body types can be carried out. By implementing the painting box concept also in the clearcoat painting section, the advantages of greater flexibility and more efficient utilization of the painting installation, which have been described above in connection with the painting section for surfacer and / or topcoat and / or topcoat basecoat, also with reference to reaches the clearcoat section.

Insbesondere kann vorgesehen sein, dass auch die Verweilzeit der Fahrzeugkarosserien in der mindestens einen Klarlackierbox fahrzeugkarosserietypspezifisch vorgegeben ist.In particular, it can be provided that the dwell time of the vehicle bodies in the at least one clear-lacquer box is also specified vehicle-body type-specific.

Aus den vorstehend bereits im Zusammenhang mit den Lackierboxen des Lackierabschnitts für Füller und/oder Decklack und/oder Decklack-Basislack angegebenen Gründen ist es ferner von Vorteil, wenn der Klarlack-Lackierabschnitt mindestens zwei Klarlackierboxen umfasst, welche parallel zueinander und unabhängig voneinander betreibbar sind.From the above already in connection with the Lackierabschnitts for Lackierabschnitts for filler and / or topcoat and / or topcoat basecoat For reasons given, it is furthermore advantageous if the clearcoat section comprises at least two clear-lacquer boxes which are operable in parallel and independently of one another.

Bei einer bevorzugten Ausgestaltung der Lackieranlage ist ferner vorgesehen, dass die Fahrzeugkarosserien, die mit Klarlack lackiert werden sollen, aus dem Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack durch einen Decklack-Basislack-Zwischentrockner in den Klarlack-Lackierabschnitt gefördert werden. Auf diese Weise ist es möglich, den Aufbau und die Betriebsweise des Decklack-Basislack-Zwischentrockners optimal auf die Trocknung des vor dem Klarlack aufgetragenen Decklack-Basislacks abzustimmen.In a preferred refinement of the painting installation, it is further provided that the vehicle bodies which are to be coated with clearcoat are conveyed from the coating section for filler and / or topcoat and / or topcoat basecoat to the clearcoat section by a topcoat basecoat intermediate dryer , In this way, it is possible to optimally match the structure and the mode of operation of the top coat basecoat intermediate dryer to the drying of the topcoat basecoat applied before the clearcoat.

Ferner kann vorgesehen sein, dass die mit Klarlack lackierten Fahrzeugkarosserien von dem Klarlack-Lackierabschnitt zu einer Karbsserieverteileinrichtung gefördert werden, von welcher Fahrzeugkarosserien wahlweise in einen von mindestens zwei verschiedenen Durchlauftrocknern abgegeben werden. Auf diese Weise ist es möglich, ein und dieselbe Karosserieverteileinrichtung sowohl für die Verteilung der Fahrzeugkarosserien auf die nachfolgenden Durchlauftrockner nach dem Durchlaufen des Lackierabschnitts für Füller und/oder Decklack und/oder Decklack-Basislack als auch für die Weiterförderung der Fahrzeugkarosserien zu dem Decklack-Durchlauftrockner nach dem Durchlaufen des Klarlackierabschnitts zu verwenden.Furthermore, it can be provided that the vehicle bodies painted with clear varnish are conveyed from the clearcoat painting section to a carburizing distribution device, from which vehicle bodies are optionally delivered to one of at least two different continuous driers. In this way it is possible, one and the same body distribution device both for the distribution of the vehicle bodies on the subsequent continuous dryer after passing through the painting section for filler and / or topcoat and / or topcoat basecoat as well as for the further promotion of the vehicle bodies to the topcoat continuous dryer after passing through the clearcoat section.

Ferner kann vorgesehen sein, dass die Lackieranlage einen Füller-Durchlauftrockner umfasst, wobei die Fahrzeugkarosserien, die den Füller-Durchlauftrockner durchlaufen haben, dem Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack zugeführt werden. Bei einer solchen Ausgestaltung der erfindungsgemäßen Lackieranlage wird der Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack also nach der Füllerlackierung und der Trocknung der Füllerlackierung erneut von den Fahrzeugkarosserien durchlaufen, so dass in demselben Lackierabschnitt sowohl die Füllerlackierung als auch die Lackierung mit Decklack bzw. mit Decklack-Basislack durchgeführt werden können, wodurch dieser Lackierabschnitt besonders effizient genutzt werden kann.Furthermore, it can be provided that the painting installation comprises a filler through-flow dryer, wherein the vehicle bodies, which have passed through the filler through-flow dryer, are supplied to the painting section for filler and / or topcoat and / or topcoat basecoat. In such an embodiment of the painting according to the invention the painting section for filler and / or topcoat and / or topcoat basecoat so again after passing the surfacer coat and drying the surfacer paint from the vehicle bodies, so that in the same Lackierabschnitt both the surfacer and the finish can be performed with topcoat or topcoat basecoat, which This painting section can be used very efficiently.

Ferner ist es günstig, wenn stromaufwärts vor dem Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack eine Reinigungseinrichtung angeordnet ist, in welcher die Fahrzeugkarosserien vor dem ersten Eintreten in den Lackierabschnitt für Füller und/oder Decklack und/oder Decklack-Basislack und nach dem Durchlaufen des Füller-Durchlauftrockners gereinigt werden. Bei dieser Ausgestaltung kann also eine gemeinsame Reinigungseinrichtung verwendet werden, um die erforderliche Reinigung der Fahrzeugkarosserien sowohl vor der Füllerlackierung als auch vor der Lackierung mit Decklack bzw. mit Decklack-Basislack durchzuführen, im Gegensatz zu der klassischen Linien-Lackieranlage, bei welcher jeweils separate Reinigungsstationen für die Reinigung der Fahrzeugkarosserien vor der Füllerlackierung und vor der Decklackierung benötigt werden.Furthermore, it is favorable if upstream of the painting section for filler and / or topcoat and / or topcoat basecoat a cleaning device is arranged, in which the vehicle bodies before the first entering the painting section for filler and / or topcoat and / or topcoat basecoat and cleaned after passing through the filler through-flow dryer. In this embodiment, therefore, a common cleaning device can be used to perform the required cleaning of the vehicle bodies both before the surfacer and before painting with topcoat or topcoat basecoat, in contrast to the classic line-painting, in which each separate cleaning stations needed for cleaning the vehicle bodies before the filler coat and before the top coat.

Das Einfahren bzw. Ausfahren der Fahrzeugkarosserien in die mindestens eine Lackierbox kann auf einander gegenüberliegenden Seiten der jeweiligen Lackierbox erfolgen, was den Vorteil bietet, dass gleichzeitig mit der Ausfahrt einer bereits lackierten Fahrzeugkarosserie aus der Lackierbox die Einfahrt einer noch zu lackierenden Fahrzeugkarosserie in dieselbe Lackierbox erfolgen kann, so dass der Fahrzeugkarosseriewechsel mit minimalen Applikationsstillstandszeiten in der Lackierbox verbunden ist.Retracting or extending the vehicle bodies into the at least one painting box can take place on opposite sides of the respective painting box, which offers the advantage that the entry of a vehicle body still to be painted into the same painting box takes place simultaneously with the exit of an already painted vehicle body from the painting box can, so that the vehicle body change is associated with minimal application downtime in the Lackierbox.

Alternativ hierzu kann aber auch vorgesehen sein, dass die Fahrzeugkarosserien auf derselben Seite der Lackierbox in die Lackierbox eingefahren und aus der Lackierbox ausgefahren werden. Eine solche Ausgestaltung der Lackierbox eignet sich insbesondere für solche Fälle, in denen ein zusätzlicher Lackierautomat für die Lackierung des Laderauminnenbereichs einer Transporterkarosserie eingesetzt wird, welcher hinter dem Heck der Fahrzeugkarosserie, auf der der Einfahrtsöffnung der Lackierbox entgegengesetzten Seite der Lackierbox, angeordnet ist, so dass auf dieser Seite dann keine Ausfahrt der lackierten Fahrzeugkarosserie möglich ist.Alternatively, however, it can also be provided that the vehicle bodies are retracted on the same side of the painting in the Lackierbox and extended from the Lackierbox. Such a refinement of the paint box is particularly suitable for cases in which an additional painting machine is used for painting the inside of the load compartment of a van body, which is arranged behind the rear of the vehicle body, on the side opposite the entry opening of the paint booth, so that On this side then no exit of the painted vehicle body is possible.

Von einer als Ganzes mit 100 bezeichneten Lackieranlage für Fahrzeugkarosserien 102 in der Großserienproduktion ist in den Fig. 1 und 2 ein Abschnitt 104 dargestellt, welcher dazu dient, die in einem vorhergehenden Abschnitt der Lackieranlage 100 bereits mit einem Grundlack versehenen Fahrzeugkarosserien mit einem Füller und mit einem Decklack oder mit einem Füller, einem Decklack-Basislack und einem Klarlack zu versehen.Of a designated as a whole with 100 paint shop for vehicle bodies 102 in mass production is in the Fig. 1 and 2 a section 104 is provided, which serves to provide the already provided in a previous section of the paint shop 100 with a base coat vehicle bodies with a filler and with a top coat or with a filler, a topcoat basecoat and a clearcoat.

Dem Abschnitt 104 werden die von dem (nicht dargestellten) Abschnitt für Grundlackierung kommenden Fahrzeugkarosserien 102 über eine mit 106 bezeichnete Einlauf-Förderstrecke zugeführt. Die Fahrzeugkarosserien 102 treten über eine Reinigungseinrichtung 108, in welcher die grundlackierten Fahrzeugkarosserien 102 für die bevorstehende Füllerlackierung gereinigt werden, in einen Lackierabschnitt 110 für Füller und Decklack ein.The section 104 is supplied with the vehicle bodywork 102 (not shown) from the vehicle body section 102 (not shown) via an inlet conveying path designated 106. The vehicle bodies 102 enter into a painting section 110 for filler and topcoat via a cleaning device 108, in which the base-lacquered vehicle bodies 102 are cleaned for the upcoming surfacer coat.

Nach erfolgter Reinigung werden die Fahrzeugkarosserien 102 aus der Reinigungseinrichtung 108 über einen Zwischenförderer 112 in eine Karosseriezuführvorrichtung 114 gefördert, welche die einlaufenden Fahrzeugkarosserien, je nach Verfügbarkeit, jeweils einer von mehreren, beispielsweise vier, Lackierboxen 116 für Füller und Decklack zuführt.After cleaning, the vehicle bodies 102 are conveyed from the cleaning device 108 via an intermediate conveyor 112 in a Karosseriezuführvorrichtung 114, which supplies the incoming vehicle bodies, depending on availability, one of several, for example four, paint boxes 116 for filler and topcoat.

Die Einfahrtrichtung 118, in welcher die Fahrzeugkarosserien 102 in die Lackierboxen 116 hineingefördert werden, ist quer zu der Förderrichtung 120 der Fahrzeugkarosserien 102 in der Förderstrecke 106 und im Zwischenförderer 112 ausgerichtet, weshalb am Eingang der Karosseriezuführvorrichtung 114 eine Drehvorrichtung 122 vorgesehen ist, welche die Fahrzeugkarosserien 102 so um eine vertikale Achse dreht, dass ihre Längsrichtung 124, welche anfänglich parallel zur Förderrichtung 120 ausgerichtet ist, anschließend parallel zur Einfahrtrichtung 118 ausgerichtet ist.The entrance direction 118, in which the vehicle bodies 102 are conveyed into the painting boxes 116, is oriented transversely to the conveying direction 120 of the vehicle bodies 102 in the conveying path 106 and in the intermediate conveyor 112, and therefore at the entrance to the body feed device 114 a rotating device 122 is provided, which covers the vehicle bodies 102 rotates about a vertical axis that its longitudinal direction 124, which is initially aligned parallel to the conveying direction 120, is then aligned parallel to the inlet direction 118.

Die so gedrehten Fahrzeugkarosserien 102 werden von der Karosseriezuführvorrichtung 114 in der Längsrichtung der Karosseriezuführvorrichtung 114 gefördert, bis das Einfahrtstor 126 der nächstliegenden freien Lackierbox 116 erreicht ist.The thus rotated vehicle bodies 102 are conveyed by the body feeding device 114 in the longitudinal direction of the body feeding device 114 until the entrance gate 126 of the nearest free painting box 116 is reached.

Anschließend wird die Fahrzeugkarosserie 102 in der Einfahrtrichtung 118 in die Lackierbox 116 hineingefördert und dort für den anschließenden Lackiervorgang stillgesetzt.Subsequently, the vehicle body 102 is conveyed in the entry direction 118 in the Lackierbox 116 and stopped there for the subsequent painting.

Eine solche Lackierbox 116 ist in Fig. 2 schematisch dargestellt, im wesentlichen quaderförmig ausgebildet und umfasst zwei sich parallel zur Einfahrtrichtung 118 erstreckende, voneinander beabstandete Seitenwände 128 und ein (nicht dargestelltes) Dach, eine der Karosseriezuführvorrichtung 114 zugewandte Einfahrtsöffnung, die mittels des Einfahrtstores 126 verschließbar ist, und eine der Einfahrtsöffnung gegenüberliegende Ausfahrtsöffnung, welche mittels eines Ausfahrttores 130 verschließbar ist.Such a paint booth 116 is in Fig. 2 shown schematically, formed substantially parallelepiped and comprises two parallel to the inlet 118 extending, spaced apart side walls 128 and a (not shown) roof, the Karosseriezuführvorrichtung 114 facing entrance opening, which is closed by means of the entrance gate 126, and an entrance opening opposite exit opening which can be closed by means of an exit gate 130.

Das Einfahrtstor 126 und das Ausfahrtstor 130 können beispielsweise als Rolltor ausgebildet sein.The entrance gate 126 and the exit gate 130 may be formed, for example, as a roller door.

Zu beiden Seiten des Förderweges der Fahrzeugkarosserien 102 durch die Lackierbox 116 befinden sich jeweils mehrere, beispielsweise jeweils zwei, Lackierautomaten 132 in Form von Lackierrobotern, welche dazu in der Lage sind, eine vollständige, vollautomatische Lackierung sämtlicher zu lackierenden Innen- und Außenflächen der Fahrzeugkarosserien 102 wahlweise mit einem Füller, mit einem Decklack oder mit einem Decklack-Basislack durchzuführen.On both sides of the conveying path of the vehicle bodies 102 through the Lackierbox 116 are each several, for example, two, paint sprayers 132 in the form of painting robots, which are capable of a complete, fully automatic painting of all painted interior and exterior surfaces of the vehicle bodies 102nd optionally with a filler, with a topcoat or with a topcoat basecoat.

Wenn eine Fahrzeugkarosserie 102 zum ersten Mal den Lackierabschnitt 110 für Füller und Decklack durchläuft, wird sie in der Lackierbox 116 innen und außen mit Füller lackiert.When a vehicle body 102 passes through the paint filler and topcoat paint section 110 for the first time, it is painted in the paint booth 116 inside and outside with filler.

Um eine vollständige Innen- und Außenlackierung durchführen zu können, sind die Lackierautomaten 132 dazu in der Lage, Lackiereinrichtungen in den Innenraum der Fahrzeugkarosserien 102 hinein zu bewegen, gegebenenfalls nachdem zuvor Türen, die Motorhaube oder der Kofferraumdeckel der Fahrzeugkarosserien 102 geöffnet worden sind.In order to be able to perform a complete interior and exterior painting, the painting machines 132 are able to move painting equipment into the interior of the vehicle bodies 102, possibly after doors, the hood or the boot lid of the vehicle bodies 102 have been opened beforehand.

Ferner sind die Lackierautomaten 132 vorzugsweise in der Längsrichtung 133 der Lackierbox 116 hin- und her beweglich.Furthermore, the automatic coating machines 132 are preferably movable back and forth in the longitudinal direction 133 of the painting box 116.

Art und Umfang der vollautomatischen Innen- und Außenlackierung in der Lackierbox 116 hängt von dem Typ der jeweils zu lackierenden Fahrzeugkarosserien 102 ab.The nature and extent of the fully automatic interior and exterior painting in the paint box 116 depends on the type of vehicle bodies 102 to be painted in each case.

Mindestens zwei verschiedene Fahrzeugkarosserietypen werden dem Abschnitt 104 der Lackieranlage 100 in zufällig gemischter Reihenfolge zugeführt.At least two different vehicle body types are supplied to section 104 of paint shop 100 in randomly-mixed order.

Beim Einfahren der Fahrzeugkarosserien 102 in die Lackierbox 116 erkennt eine Anlagensteuerung der Lackierbox mittels eines hierfür vorgesehenen Sensors aufgrund eines an der Fahrzeugkarosserie 102 angebrachten Identifikators (beispielsweise eines mit einem Lochcode versehenen Blechs oder eines Transponders), um welchen Karosserietyp es sich handelt, so dass anschließend das diesem Karosserietyp zugeordnete Lackierprogramm durchgeführt werden kann. Alternativ hierzu ist auch möglich, dass der Steuerung der Lackierbox 116 von einer übergeordneten zentralen Anlagensteuerung mitgeteilt wird, von welchem Typ die gerade in die betreffende Lackierbox 116 einfahrende Fahrzeugkarosserie 102 ist.When retracting the vehicle bodies 102 into the painting box 116, a system control of the painting box recognizes by means of a sensor provided for this purpose on the vehicle body 102 attached identifier (for example, provided with a hole code sheet or a transponder), which body type is, so that subsequently the painting program associated with this body type can be carried out. Alternatively, it is also possible that the control of the paint booth 116 is communicated by a superordinate central system control, of which type the vehicle body 102 which is currently entering the relevant paint booth 116 is.

Da für die Innen- und Außenlackierung der Fahrzeugkarosserien 102 je nach dem Typ der Fahrzeugkarosserie eine unterschiedliche Zeit benötigt wird, ist die Verweilzeit der Fahrzeugkarosserien 102, in Abhängigkeit vom jeweiligen Fahrzeugkarosserietyp, unterschiedlich, jedoch für jeden Karosserietyp jeweils fest vorgegeben.Since a different time is required for the interior and exterior painting of the vehicle bodies 102, depending on the type of vehicle body, the dwell time of the vehicle bodies 102 is different depending on the respective vehicle body type, but fixed for each body type.

Am Ende der vorgegebenen Verweilzeit wird das Ausfahrtstor 130 geöffnet und die Fahrzeugkarosserie 102 in der parallel zur Einfahrtsrichtung 118 verlaufenden Ausfahrtsrichtung 134 aus der Lackierbox 116 heraus auf eine Karosserieabführvorrichtung 136 gefördert, welche die aus den Lackierboxen 116 ausfahrenden Fahrzeugkarosserien 102 sammelt und über einen Zwischenförderer 138 einer Kontrollstation 141 zuführt.At the end of the predetermined residence time, the exit gate 130 is opened and the vehicle body 102 is conveyed out of the paint booth 116 in the exit direction 134 running parallel to the entrance direction 118 onto a body removal device 136 which collects the vehicle bodies 102 extending from the paint booths 116 and via an intermediate conveyor 138 Control station 141 supplies.

Hierbei kann gleichzeitig mit der Ausfahrt einer bereits lackierten Fahrzeugkarosserie 102 aus einer Lackierbox 116 die Einfahrt einer zu lackierenden Fahrzeugkarosserie 102 in dieselbe Lackierbox 116 erfolgen.In this case, at the same time as the exit of an already painted vehicle body 102 from a paint box 116, the entry of a vehicle body 102 to be painted into the same paint box 116 can take place.

Die Karosserieabführvorrichtung 136 ist an ihrem Ausgang mit einer Drehvorrichtung 140 versehen, welche die Fahrzeugkarosserien 102 so um eine vertikale Achse dreht, dass ihre Längsrichtung 124, welche beim Ausfahren aus den Lackierboxen 116 quer zur Förderrichtung 142 des Zwischenförderers 138 ausgerichtet ist, anschließend parallel zur Förderrichtung 142 verläuft.The body removal device 136 is provided at its output with a rotating device 140, which rotates the vehicle bodies 102 about a vertical axis such that their longitudinal direction 124, which is aligned transversely to the conveying direction 142 of the intermediate conveyor 138 when extending out of the painting boxes 116, is then parallel to the conveying direction 142 runs.

In der Kontrollstation 141 wird kontrolliert, ob die in dem Lackierabschnitt 110 für Füller und Decklack durchgeführte Lackierung ordnungsgemäß durchgeführt worden ist. Beim ersten Durchlauf einer Fahrzeugkarosserie 102 durch den Lackierabschnitt 110 wird also geprüft, ob die Füllerlackierung ordnungsgemäß durchgeführt worden ist.In the control station 141, it is checked whether the coating carried out in the filler and topcoat painting section 110 has been performed properly. During the first pass of a vehicle body 102 through the painting section 110, it is thus checked whether the surfacer coating has been carried out properly.

Anschließend werden die Fahrzeugkarosserien 102 aus der Kontrollstation 141 auf eine Karosserieverteileinrichtung 144 gefördert, von welcher jede Fahrzeugkarosserie 102, je nach erreichtem Verfahrensstadium, an einen von drei nachfolgenden Durchlauftrocknern abgegeben wird, nämlich an einen Füller-Durchlauftrockner 146, an einen Decklack-Durchlauftrockner 148 oder an einen Zwischen-Durchlauftrockner 150.Subsequently, the vehicle bodies 102 are conveyed out of the control station 141 onto a body distribution device 144, from which each vehicle body 102 is delivered, depending on the process stage reached, to one of three subsequent continuous dryers, namely to a continuous flow dryer 146, to a topcoat continuous dryer 148 or to an intermediate passage dryer 150.

Nach dem ersten Durchlaufen des Lackierabschnitts 110 für Füller und Decklack, bei welchem die Fahrzeugkarosserien 102 mit Füller lackiert worden sind, gibt die Karosserieverteileinrichtung 144 die Fahrzeugkarosserien 102 über einen Zwischenförderer 152 an den Füller-Durchlauftrockner 146 ab, durch welchen die Fahrzeugkarosserien 102 dann parallel zur Förderrichtung 142 hindurch gefördert werden, wobei die Füllerlackierung getrocknet wird.After first passing through the filler and topcoat painting section 110 in which the vehicle bodies 102 have been painted with filler, the body-splitter 144 discharges the vehicle bodies 102 to the filler pass-through dryer 146 via an intermediate conveyor 152, through which the vehicle bodies 102 are then parallel to the vehicle body Conveying direction 142 are conveyed through, wherein the surfacer is dried.

Am Ausgang des Füller-Durchlauftrockners 146 kann eine Kühlzone 154 vorgesehen sein.At the exit of the filler pass-through dryer 146, a cooling zone 154 may be provided.

Nach Verlassen des Füller-Durchlauftrockners 146 werden die getrockneten Fahrzeugkarosserien 102 über eine Zwischen-Förderstrecke 156 erneut der Einlauf-Förderstrecke 106 zugeführt und somit zum zweiten Mal in die Reinigungseinrichtung 108 am Eingang des Lackierabschnittes 110 für Füller und Decklack gefördert.After leaving the filler through-flow dryer 146, the dried vehicle bodies 102 are fed again via an intermediate conveying path 156 to the inlet conveyor section 106 and thus conveyed for the second time into the cleaning device 108 at the entrance of the coating section 110 for filler and topcoat.

Nach Reinigung in der Reinigungseinrichtung 108 gelangen die Fahrzeugkarosserien 102, die bereits mit Füller lackiert worden sind, in der vorstehend beschriebenen Weise über die Karosseriezuführvorrichtung 114 in eine Lackierbox 116, welche gerade unbelegt ist, und werden in der betreffenden Lackierbox 116 während einer fahrzeugkarosserietypspezifisch vorgegebenen Verweilzeit vollautomatisch mit einer Innen- und einer Außenlackierung mit einem Decklack oder mit einem Decklack-Basislack versehen.After cleaning in the cleaning device 108, the vehicle bodies 102 which have already been painted with filler in the manner described above via the body feeder 114 in a Lackierbox 116, which is currently unoccupied, and are in the relevant Lackierbox 116 during a vehicle body type specific predetermined residence time Fully automatic with an interior and an exterior finish with a topcoat or with a topcoat basecoat.

Anschließend werden die mit dem Decklack oder dem Decklack-Basislack versehenen Fahrzeugkarosserien 102 von der Karosserieabführvorrichtung 136 der Kontrollstation 141 zugeführt, in welcher der aufgetragene Decklack bzw. Decklack-Basislack kontrolliert wird.Subsequently, the vehicle bodies 102 provided with the topcoat or the topcoat basecoat are supplied by the body removal device 136 to the control station 141, in which the applied topcoat or topcoat basecoat is controlled.

Wenn ein aufgetragener Decklack die letzte Lackschicht bildet, welche auf die Fahrzeugkarosserien 102 aufzutragen ist, wird die Fahrzeugkarosserie 102 anschließend von der Karosserieverteileinrichtung 144 über einen Zwischenförderer 156 an den Decklack-Durchlauftrockner 148 abgegeben.When a coated topcoat forms the final paint layer to be applied to the vehicle bodies 102, the vehicle body 102 is subsequently discharged from the body distribution device 144 via an intermediate conveyor 156 to the topcoat continuous dryer 148.

Auf einen aufgetragenen Decklack-Basislack, insbesondere einen Metallic-Lack, muss jedoch noch ein Klarlack aufgetragen werden. In diesem Fall wird die betreffende Fahrzeugkarosserie 102 von der Karosserieverteileinrichtung 144 über einen Zwischenförderer 158 an den Zwischen-Durchlauftrockner 150 abgegeben, durch welchen die betreffende Fahrzeugkarosserie 102 parallel zur Förderrichtung 120 hindurch gefördert wird, wobei der aufgetragene Decklack-Basislack getrocknet wird.On a coated topcoat basecoat, especially a metallic paint, but still a clear coat must be applied. In this case, the subject vehicle body 102 is replaced by the body distribution device 144 is delivered via an intermediate conveyor 158 to the intermediate passage dryer 150, through which the subject vehicle body 102 is conveyed parallel to the conveying direction 120 therethrough, wherein the applied topcoat basecoat is dried.

Am Ausgang des Zwischen-Durchlauftrockners 150 kann eine Kühlzone 160 angeordnet sein.At the exit of the intermediate pass-through dryer 150, a cooling zone 160 may be arranged.

Aus dem Zwischen-Durchlauftrockner 150 gelangen die Fahrzeugkarosserien 102 in einen Lackierabschnitt 162 für Klarlack, welcher mehrere, beispielsweise zwei, Lackierboxen 164 für Klarlack umfasst, welche ebenso aufgebaut sind wie die Lackierboxen 116 des Lackierabschnitts 110 für Füller und Decklack.From the intermediate pass-through dryer 150, the vehicle bodies 102 pass into a varnishing section 162 for clearcoat, which comprises a plurality of, for example two, varnishing boxes 164 for clearcoat, which are constructed in the same way as the varnishing boxes 116 of the coating section 110 for the filler and topcoat.

Die den Zwischen-Durchlauftrockner 150 verlassenden Fahrzeugkarosserien 102, die mit der Decklack-Basislackierung versehen sind, werden mittels einer dem Zwischen-Durchlauftrockner 150 nachgeschalteten Karosseriezuführvorrichtung 166 einer unbelegten Lackierbox 164 für Klarlack zugeführt.The vehicle bodies 102 leaving the intermediate passage dryer 150, which are provided with the topcoat basecoat, are supplied to a blank paint booth 164 for clearcoat by means of a bodyfeeder 166 connected downstream of the intermediate passage dryer 150.

Da die Einfahrtsrichtung 168, längs welcher die Fahrzeugkarosserien in die Lackierboxen 164 für Klarlack einfahren, quer zu der Förderrichtung 120 des Zwischen-Durchlauftrockners 150 ausgerichtet ist, umfasst die Karosseriezuführvorrichtung 166 zwei Drehvorrichtungen 170, mittels derer die Fahrzeugkarosserien 102 so um eine vertikale Achse gedreht werden, dass ihre Längsrichtung 124, die zunächst parallel zur Förderrichtung 120 ausgerichtet ist, anschließend parallel zur Einfahrtsrichtung 168 verläuft.Since the entry direction 168, along which the vehicle bodies enter the paint booths 164 for clearcoat, is oriented transversely to the conveying direction 120 of the intermediate pass dryer 150, the body feeder 166 comprises two rotary devices 170, by means of which the vehicle bodies 102 are rotated about a vertical axis in that its longitudinal direction 124, which is initially oriented parallel to the conveying direction 120, subsequently runs parallel to the entry direction 168.

Nach dem Einfahren in eine der Lackierboxen 164 für Klarlack bei geöffnetem Einfahrtstor 126 und nach Stillsetzen innerhalb der Lackierbox 164 wird in der fahrtstor 130, eine vollautomatische Innen- und Außenlackierung der Fahrzeugkarosserien 102 mit Klarlack durchgeführt, wobei die jeweilige Verweilzeit einer Fahrzeugkarosserie 102 in einer der Lackierboxen 164 für Klarlack in Abhängigkeit vom jeweiligen Fahrzeugkarosserietyp fest vorgegeben ist.After entering one of the Lackierboxen 164 for clear coat with the entrance gate 126 and after stopping within the Lackierbox 164 is in the drive door 130, a fully automatic interior and exterior painting of the vehicle bodies 102 carried out with clear coat, wherein the respective residence time of a vehicle body 102 is fixed in one of Lackierboxen 164 clearcoat depending on the vehicle body type.

Nach Ablauf der vorgegebenen Verweilzeit wird das Ausfahrtstor 130 geöffnet und die betreffende Fahrzeugkarosserie 102 in der zur Einfahrtsrichtung 168 parallelen Ausfahrtsrichtung 172 aus der Lackierbox 164 für Klarlack heraus gefahren und gelangt so auf eine Karosserieabführvorrichtung 174, welche die Fahrzeugkarosserien 102, die mit dem Klarlack versehen sind, in der quer zu ihrer Längsrichtung 124 ausgerichteten Förderrichtung 142 zu einem Endbereich der Karosserieabführvorrichtung 174 fördert, von wo die Fahrzeugkarosserien 102 weiter über einen Zwischenförderer 176 längs einer antiparallel zur Ausfahrtsrichtung 172 gerichteten Förderrichtung 178 zu einem Anfangsbereich der Karosserieabführvorrichtung 136 des Lackierabschnitts 110 für Füller und Decklack gefördert werden.After the predetermined residence time expires, the exit gate 130 is opened and the vehicle body 102 in question is moved out of the painting booth 164 for clearcoat 17 in the direction of exit 168 parallel to the entry direction 168 and thus arrives at a body removal device 174 which is provided with the vehicle bodies 102 provided with the clearcoat in which transverse to its longitudinal direction 124 aligned conveying direction 142 to an end portion of the Karosserieabführvorten 174 promotes, from where the vehicle bodies 102 further via an intermediate conveyor 176 along an anti-parallel to the exit direction 172 directed conveying direction 178 to an initial region of the Karosserieabführvorrichtung 136 of the coating section 110 for filler and Topcoat be promoted.

Diese Karosserieabführvorrichtung 136 fördert die mit dem Klarlack versehenen Fahrzeugkarosserien 102, unter Drehung in der Drehvorrichtung 140, bis zu der Kontrollstation 141, in welcher die aufgebrachte Klarlackierung überprüft wird.This body-removing device 136 conveys the clear-coated vehicle bodies 102, rotating in the rotating device 140, to the control station 141, in which the applied clearcoat is checked.

Von der Kontrollstation 141 gelangen die klarlackierten Fahrzeugkarosserien 102 über die Karosserieverteileinrichtung 144 und den Zwischenförderer 156 in den Decklack-Durchlauftrockner 148.From the control station 141, the clear-lacquered vehicle bodies 102 pass through the body-distributing device 144 and the intermediate conveyor 156 into the top-coat continuous-flow dryer 148.

Die Fahrzeugkarosserien 102 werden in der Förderrichtung 142 durch den Decklack-Durchlauftrockner 148 hindurchgefördert und dabei getrocknet.The vehicle bodies 102 are conveyed through in the conveying direction 142 by the top coat through-drier 148 and thereby dried.

Am Ausgang des Decklack-Durchlauftrockners 148 kann eine Kühlzone 180 vorgesehen sein.A cooling zone 180 may be provided at the exit of the topcoat run-through dryer 148.

Nach Verlassen des Decklack-Durchlauftrockners 148 werden die klarlackierten Fahrzeugkarosserien 102, ebenso wie die nur mit einem Decklack ohne anschließende Klarlackierung versehenen Fahrzeugkarosserien 102, zu den auf die Lackierung folgenden Fertigungsstufen weiter gefördert.After leaving the top coat through-drier 148, the clear-painted vehicle bodies 102, as well as the vehicle bodies 102 provided with a topcoat without subsequent clearcoating, are further conveyed to the production stages following the coating.

Eine Fahrzeugkarosserie 102, welche mit einem Füller und mit Decklack lackiert wird, durchläuft also, von der Grundlackierung kommend, nacheinander die Reinigungseinrichtung 108, eine der Lackierboxen 116 für Füller und Decklack, in welcher die Fahrzeugkarosserie 102 mit Füller lackiert wird, die Kontrollstation 141, in welcher die Füllerlackierung kontrolliert wird, den Füller-Durchlauftrockner 146, erneut die Reinigungseinrichtung 108, wiederum eine der Lackierboxen 116 für Füller und Decklack, wobei diese Lackierbox 116 dieselbe Lackierbox 116 wie beim ersten Durchgang oder aber eine andere sein kann, wobei die Fahrzeugkarosserie 102 mit einem Decklack lackiert wird, erneut die Kontrollstation 141, in welcher die Decklackierung kontrolliert wird, und schließlich den Decklack-Durchlauftrockner 148.A vehicle body 102, which is painted with a filler and with a topcoat, thus passes successively, coming from the basecoat, the cleaning device 108, one of the painting boxes 116 for filler and topcoat, in which the vehicle body 102 is painted with filler, the control station 141, in which the surfacer coating is controlled, the filler-through-drier 146, again the cleaning device 108, again one of the paint boxes 116 for filler and topcoat, this Lackierbox 116 may be the same Lackierbox 116 as in the first round or another, wherein the vehicle body 102nd is painted with a topcoat, again the control station 141 in which the topcoat is controlled, and finally the topcoat continuous dryer 148.

Eine Fahrzeugkarosserie 102, welche mit Füller, mit einem Decklack-Basislack und mit einem Klarlack lackiert wird, durchläuft, von der Grundlackierung kommend, nacheinander die Reinigungseinrichtung 108, eine der Lackierboxen 116 für Füller und Decklack, wobei die Fahrzeugkarosserie 102 mit Füller lackiert wird, die Kontrollstation 141, in welcher die Füllerlackierung kontrolliert wird, den Füller-Durchlauftrockner 146, erneut die Reinigungseinrichtung 108, eine der Lackierboxen 116 für Füller und Decklack, wobei diese Lackierbox 116 dieselbe Lackierbox 116 wie beim ersten Durchlauf oder aber eine andere Lackierbox 116 sein kann, wobei die Fahrzeugkarosserie 102 in der Lackierbox 116 mit einem Decklack-Basislack lackiert wird, erneut die Kontrollstation 141, in welcher die Decklack-Basislackierung kontrolliert wird, den Zwischen-Durchlauftrockner 150, eine der Lackierboxen 164 für Klarlack, in welcher die Fahrzeugkarosserie 102 mit Klarlack lackiert wird, erneut die Kontrollstation 141, in welcher die Klarlackierung kontrolliert wird, und schließlich den Decklack-Durchlauftrockner 148.A vehicle body 102, which is painted with filler, with a topcoat basecoat and with a clearcoat, passes successively from the basecoat, the cleaning device 108, one of the paint booths 116 for filler and topcoat, wherein the vehicle body 102 is painted with filler, the control station 141, in which the surfacer is controlled, the filler-through-drier 146, again the cleaning device 108, one of the paint boxes 116 for filler and topcoat, this Lackierbox 116 the same Lackierbox 116 as in the first pass or another Lackierbox 116 may be, wherein the vehicle body 102 is painted in the Lackierbox 116 with a topcoat basecoat, again the control station 141, in which the topcoat basecoat is controlled, the intermediate continuous dryer 150, one of Lackierboxen 164 for clearcoat, in which the vehicle body 102 is painted with clear lacquer, again the control station 141, in which the clearcoat is controlled, and finally the topcoat continuous dryer 148.

Dabei werden die Fahrzeugkarosserien 102 außerhalb der Lackierboxen 116 bzw. 164 kontinuierlich oder taktweise, mit einer vorgegebenen Taktzeit, gefördert.In this case, the vehicle bodies 102 are conveyed outside the painting boxes 116 and 164, respectively, continuously or in cycles, with a predetermined cycle time.

In den Lackierboxen 116 bzw. 164 werden die Fahrzeugkarosserien 102 hingegen für die Zeitdauer des jeweiligen Lackiervorgangs stillgesetzt, wobei die Verweilzeit in der jeweiligen Lackierbox 116 bzw. 164 in Abhängigkeit vom Typ der jeweiligen Fahrzeugkarosserie und in Abhängigkeit von der Art des jeweiligen Lackiervorgangs vorgegeben ist und wobei die Verweilzeiten in den Lackierboxen 116 und 164 völlig unabhängig von irgendwelchen Taktzeiten, mit denen die Fördervorrichtungen außerhalb der Lackierboxen 116 und 164 arbeiten, vorgegeben werden können.In the painting boxes 116 and 164, however, the vehicle bodies 102 are shut down for the duration of the respective painting process, wherein the residence time in the respective Lackierbox 116 or 164 depending on the type of the respective vehicle body and depending on the nature of the respective painting process is specified and wherein the dwell times in paint booths 116 and 164 may be dictated entirely independent of any cycle times that the dispensers operate outside paint booths 116 and 164.

Eine in den Fig. 3 und 4 dargestellte zweite Ausführungsform einer Lackieranlage 100 unterscheidet sich von der vorstehend beschriebenen ersten Ausführungsform dadurch, dass die Lackierboxen 116 für Füller und Decklack nicht jeweils ein Einfahrtstor 126 und ein auf der gegenüberliegenden Seite der Lackierbox angeordnetes Ausfahrtstor 130 aufweisen, sondern nur ein einziges Zugangstor 182, welches auf der der Karosseriezuführvorrichtung 114 zugewandten Seite jeder Lackierbox 116 für Füller und Decklack angeordnet ist.One in the Fig. 3 and 4 illustrated second embodiment of a paint shop 100 differs from the first embodiment described above in that the Lackierboxen 116 for filler and topcoat not each have a gateway 126 and arranged on the opposite side of the Lackierbox exit gate 130, but only a single access port 182, which is arranged on the side facing the body feed device 114 side of each paint sprayer 116 for filler and topcoat.

Bei dieser Ausführungsform sind ferner die Lackierboxen 116 für Füller und Decklack nicht zwischen der Karosseriezuführvorrichtung 114 und der Karosserieabführvorrichtung 136 des Lackierabschnitts 110 für Füller und Decklack angeordnet, sondern vielmehr auf der der Karosserieabführvorrichtung 136 abgewandten Seite der Karosseriezuführvorrichtung 114.Further, in this embodiment, the paint filler boxes 116 are not disposed between the body feed device 114 and the body discharge device 136 of the filler and topcoat paint section 110, but rather on the side of the body feed device 114 facing away from the body unloading device 136.

Die mit dem Füller bzw. mit dem Decklack zu versehenden Fahrzeugkarosserien 102 werden bei dieser Ausführungsform demnach in einer quer zur Förderrichtung 120 gerichteten Einfahrtsrichtung 118 durch das Zugangstor 182 in die Lackierbox 116 für Füller und Decklack eingefahren, in der Lackierbox 116 stillgesetzt und mittels der darin angeordneten Lackierautomaten 132 lackiert, und nach der vorgegebenen Verweilzeit in der Lackierbox 116 für Füller und Decklack und nach Öffnen des Zugangstors 182 in der zur Einfahrtsrichtung 118 entgegengesetzten Ausfahrtsrichtung 134 aus der Lackierbox 116 ausgefahren und über die Karosseriezuführvorrichtung 114 hinweg auf die Karosserieabführvorrichtung 136 gefördert, welche die Fahrzeugkarosserien 102, wie bei der ersten Ausführungsform, zu der Kontrollstation 141 hin bewegt.In this embodiment, the vehicle bodies 102 to be provided with the filler or with the topcoat are therefore moved into the painting booth 116 for filler and topcoat in the entry direction 118 directed transversely to the conveying direction 120, shut down in the painting booth 116 and by means of the latter arranged Lackierautomaten 132 painted, and after the predetermined residence time in the Lackierbox 116 for filler and topcoat and after opening of the access gate 182 in the direction of entry 118 opposite exit direction 134 extended from the Lackierbox 116 and promoted on the Karosseriesereabführvorrichtung 136 on the Karosserieserzufführvorrichtung 136, which the vehicle bodies 102 are moved toward the control station 141 as in the first embodiment.

Die Lackierboxen 116 für Füller und Decklack dieser Ausführungsform weisen an ihrer der Zugangsöffnung abgewandten Stirnseite eine Erweiterung 184 auf, welche einen zusätzlichen Lackierautomaten 186 in Form eines Lackierroboters aufnimmt, welcher insbesondere dafür vorgesehen ist, bei einem Transporterfahrzeug nach Öffnen der rückwärtigen Ladeklappe sich in den Laderaum der Tranporterkarosserie hinein zu bewegen und die Innenflächen des Laderaums mit Füller bzw. mit Decklack oder Decklack-Basislack zu lackieren.The Lackierboxen 116 for filler and topcoat this embodiment have at their end facing away from the access opening an extension 184 which receives an additional Lackierautomaten 186 in the form of a Lackierroboters, which is particularly intended for a transporter vehicle after opening the rear tailgate into the cargo space move the transporter body into it and paint the interior surfaces of the cargo space with filler or with topcoat or topcoat basecoat.

Diese Ausführungsform bietet also den Vorteil, dass insbesondere im Fall der Lackierung von Transporterfahrzeugen die Verweilzeiten in den Lackierboxen 116 für Füller und Decklack verringert werden können.Thus, this embodiment offers the advantage that, in particular in the case of the painting of transporter vehicles, the residence times in the paint boxes 116 for filler and topcoat can be reduced.

Auch die Lackierboxen 164 für Klarlack im Lackierabschnitt 162 für Klarlack sind bei der zweiten Ausführungsform so ausgebildet, wie in Fig. 4 dargestellt, das heißt mit nur einem Zugangstor 182, das auf der Seite der Karosseriezuführvorrichtung 166 angeordnet ist.The varnishing boxes 164 for clearcoat in the varnishing portion 162 for clearcoat are also formed in the second embodiment as in FIG Fig. 4 that is, with only one access gate 182 arranged on the side of the body feeder 166.

Ferner sind auch die Lackierboxen 164 für Klarlack mit einem zusätzlichen Lackierautomaten 186 für die Lackierung des Laderauminnenbereichs versehen.Furthermore, the paint boxes 164 for clearcoat are also provided with an additional coating machine 186 for painting the inside of the load compartment.

Nach der Einfahrt in der Einfahrtsrichtung 168, der Lackierung mit Klarlack in der jeweiligen Lackierbox 164 für Klarlack und nach der Ausfahrt in der der Einfahrtsrichtung 168 entgegengesetzten Ausfahrtsrichtung 172 werden die klarlackierten Fahrzeugkarosserien 102 über die Karosseriezuführvorrichtung 166 hinweg direkt auf die Karosserieabführvorrichtung 136 des Lackierabschnitts 110 für Füller und Decklack gefördert, von wo die klarlackierten Fahrzeugkarosserien 102 dann über die Kontrollstation 141 und die Karosserieverteileinrichtung 144 in den Decklack-Durchlauftrockner 148 gelangen.After entering the entryway 168, painting with clearcoat in the respective paint booth 164 for clearcoat and after exiting in the exit direction 178 opposite exit direction 168, the clear painted vehicle bodies 102 are moved across the bodyfeeder 166 directly onto the bodywork removal apparatus 136 of the painting section 110 Supplied filler and topcoat, from where the clear-painted vehicle bodies 102 then pass through the control station 141 and the body distribution device 144 in the top coat continuous drier 148.
