Description

Die Erfindung betrifft eine Beschichtungsanlage gemäß dem Oberbegriff den Anspruchs 1. Insbesondere handelt es sich um die Serienbeschichtung von Fahrzeugkarossen und anderen Werkstücken mit linear z. B. parallel zur Werkstückförderrichtung verfahrbaren Robotern, obwohl die Erfindung u.a. auch für die bei der Fahrzeuglackierung ebenfalls üblichen Dach- und Seitenmaschinen anwendbar ist.The invention relates to a coating system according to the preamble of claim 1. In particular, it is the series coating of vehicle bodies and other workpieces with linear z. B. parallel to the workpiece conveying direction movable robots, although the invention u.a. also applicable to the vehicle and vehicle also usual roof and side machines.

Bei Dach- und Seitenmaschinen zur Beschichtung von Fahrzeugkarossen sind die Zerstäuber an linear verfahrbaren Schlitten angeordnet, die in einer schlitzartigen Öffnung eines Gehäuses der Beschichtungsmaschine geführt und an den dem Gehäuseinneren zugewandten Seiten mit ins Gehäuseinnere führenden Versorgungsleitungen für die Zerstäuber verbunden sind, wobei die Gehäuseöffnung zum Schutz des Innenraums gegen die Umgebung mit einem sich mit dem Schlitten verschiebenden Band abgedeckt wird (DE 19820527 C1, WO 95/09697). Üblicherweise werden bisher bei Beschichtungsanlagen die die Gehäuseöffnung abdeckenden Abdeckbänder mit ihrem einen Ende an jeweils einer Stirnseite des Schlittens befestigt, während das andere Abdeckbandende mit Hilfe von Rollen, die von Motoren oder Federpaketen angetrieben sein können, je nach der momentanen Bewegungsrichtung des Schlittens auf- und abgewickelt wird. Es ist auch möglich, ein umlaufendes, an den beiden Stirnseiten des Schlittens befestigtes und auf der Rückseite des Schlittens zurückgeführtes Abdeckband vorzusehen.In roof and side machines for coating vehicle bodies, the atomizers are arranged on linearly movable carriages, which are guided in a slot-like opening of a housing of the coating machine and connected to the inside of the housing facing the inside of the supply lines leading to the atomizer, wherein the housing opening to Protecting the interior against the environment is covered with a moving with the carriage band (DE 19820527 C1, WO 95/09697). Usually, in coating systems, the covering opening covering the housing opening is fastened with its one end to one end face of the carriage, while the other Abdeckbandende with the help of rollers that can be driven by motors or spring assemblies, depending on the current direction of movement of the carriage up and is handled. It is also possible to provide a circumferential, attached to the two end faces of the carriage and returned to the back of the carriage masking tape.

Nachteilig ist bei diesen Konstruktionen u.a., dass durch das Aufrollen der zur Gehäuseaußenseite weisenden, z. B. mit Beschichtungsmaterial verschmutzten Seite des Abdeckbandes die Innenseite des Abdeckbandes ebenfalls verschmutzt wird, wobei es in der Folge auch zu einem Verkleben des aufgerollten Abdeckbandes kommen kann. Insbesondere bei einem umlaufenden Abdeckband können Abriebpartikel auf den zu beschichtenden Gegenstand fallen und somit Lackfehler verursachen. Außerdem sind durch die Massenträgheit des Aufwickelmechanismus der Verfahrgeschwindigkeit des Schlittens Grenzen gesetzt oder sehr große Antriebsmotore nötig. Ebenfalls nachteilig sind bei den bekannten Konstruktionen die Länge und das Gewicht der Abdeckbänder bei größeren Verfahrwegen des Schlittens, der große Platzbedarf für Umlenk- und Rückführmechanismen und die Abdeckung der Rückführung des Abdeckbandes.A disadvantage of these constructions, inter alia, that by rolling up facing the outside of the housing, z. B. soiled with coating material side of the cover, the inside of the cover strip is also dirty, and it also in the episode to a gluing of the rolled cover strip can come. In particular, in the case of a revolving masking tape, abrasion particles can fall on the object to be coated and thus cause paint defects. In addition, set by the inertia of the take-up of the speed of movement of the carriage limits or very large drive motors needed. Also disadvantageous in the known constructions, the length and weight of the cover strips for larger travel distances of the carriage, the large space requirement for deflection and return mechanisms and the cover of the return of the cover.

Ein besonderes Problem ergibt sich darüber hinaus dann, wenn zwei oder mehr Schlitten mit veränderlichem gegenseitigem Abstand vorhanden sein sollen. Ein typisches Beispiel hierfür ist eine Beschichtungsanlage mit auf einer gemeinsamen Schienenkonstruktion verfahrbaren Robotern, deren gegenseitiger Abstand sich während des Betriebes ständig verändert, so dass die bekannten Bandabdeckkonstruktionen nicht verwendet werden können. Bei derartigen Beschichtungsanlagen musste man sich daher bisher damit begnügen, die Gehäuseöffnungen mit einem Luftvorhang abzudecken.A particular problem also arises when two or more carriages with variable mutual distance should be present. A typical example of this is a coating system with robots movable on a common rail construction, the mutual distance of which constantly changes during operation, so that the known band cover constructions can not be used. For such coating systems, therefore, it has hitherto been necessary to cover the housing openings with an air curtain.

Aus DE 38 17 773 A1 ist eine Abdeckvorrichtung für die Lauf-und Führungsrollen des Portals einer als verfahrbare Portalmaschine ausgebildeten Bearbeitungsmaschine insbesondere für Holz- oder Kunststoffplatten bekannt, bei der auf den beiden Portalseiten jeweils ein stationäres Abdeckband befestigt ist, das durch Niederhalte-Walzen auf die jeweilige Rollenlauffläche gedrückt und zwischen den Niederhalte-Walzen durch Führungselemente von der Lauffläche abgehoben wird. Dadurch werden die Führungsrollen und ihre Laufflächen vor Verschmutzungen geschützt. Eine im Prinzip ähnliche Abhebeeinrichtung ist aus EP 1 095 715 A2 für ein flexibles Abdeckband auf einer Saugkanalöffnung einer Absaugvorrichtung in einer Bearbeitungsmaschine bekannt.From DE 38 17 773 A1 discloses a covering for the running and guiding rollers of the portal of a trained as a movable gantry machine processing machine especially for wood or plastic plates is known, in which a stationary cover strip is attached to the two portal sides, by the hold-down rollers pressed the respective roller tread and is lifted between the hold-down rollers by guide elements of the tread. As a result, the guide rollers and their treads are protected from contamination. A similar lifting device is known from EP 1 095 715 A2 for a flexible cover strip on a suction channel opening of a suction device in a processing machine.

Der Erfindung liegt die Aufgabe zugrunde, eine Beschichtungsanlage anzugeben, bei der die oben erwähnten Nachteile vermieden werden und die Gehäuseöffnung auf einfache Weise auch dann abgedeckt werden kann, wenn mehrere Schlitten mit veränderlichem gegenseitigem Abstand vorhanden sind.The invention has for its object to provide a coating system in which the above-mentioned disadvantages are avoided and the housing opening can be covered in a simple manner even if several carriages are available with variable mutual distance.

Diese Aufgabe wird durch die Merkmale der Beschichtungsanlage gemäß Anspruch 1 gelöst.This object is achieved by the features of the coating system according to claim 1.

Durch das stationäre Abdeckband ist es möglich, beliebig viele Schlitten auf einer Schienenkonstruktion anzuordnen und dennoch eine gleichzeitige Abdeckung der Gehäuseöffnung durch ein gemeinsames Abdeckband zu erreichen, ohne Beeinträchtigung durch jeweilige Versorgungsleitungen an jedem Schlitten.Due to the stationary cover strip, it is possible to arrange any number of carriages on a rail construction and yet a simultaneous cover of the housing opening by a common To reach masking tape, without interference by respective supply lines on each carriage.

Zugleich wird die bisher bestehende Gefahr des Verklebens von Bandlagen übereinander bzw. ihrer Innen- und Außenseiten wie beim bisherigen Aufrollen ausgeschlossen. Auch ist der Verschleiß des feststehenden Abdeckbandes wesentlich geringer als bei den bekannten Konstruktionen, wodurch zugleich die Störungsgefahr durch Abriebpartikel reduziert wird. Die Erfindung lässt sich mit einfachen Mitteln realisieren. Das Abdeckband muss kaum länger sein als die abzudeckende Gehäuseöffnung. Eine Bandlängung kann durch einfache Einrichtungen kompensiert werden. Die komplizierten Mechanismen zur Führung und Umlenkung der bekannten bewegten Abdeckbänder entfallen.At the same time the existing risk of sticking tape layers one above the other or their inner and outer sides is excluded as in the previous rolling up. The wear of the fixed cover strip is much lower than in the known constructions, whereby at the same time the risk of interference is reduced by abrasion particles. The invention can be realized with simple means. The masking tape does not have to be much longer than the housing opening to be covered. A band elongation can be compensated by simple means. The complicated mechanisms for guiding and deflecting the known moving cover bands omitted.

Das Abdeckband kann mit seinen Enden am Gehäuse befestigt sein, doch wird die Abdichtwirkung des Abdeckbandes verbessert, wenn die Beschichtungsanlage eine Spanneinrichtung zum Spannen des Abdeckbandes aufweist.The cover strip may be fastened with its ends to the housing, but the sealing effect of the cover strip is improved if the coating installation has a tensioning device for tensioning the cover strip.

Zum Schutz gegen unbeabsichtigtes Abheben des Abdeckbandes von der Gehäuseöffnung und auch wegen einer besseren Dichtwirkung kann das Abdeckband außerhalb des von der Abhebeeinrichtung abgehobenen Bereiches im Gehäuseinneren an der Öffnung anliegen.To protect against unintentional lifting of the cover strip from the housing opening and also because of a better sealing effect, the cover strip may rest outside of the lifted off the Abhebeeinrichtung area inside the housing at the opening.

Fig. 1 zeigt ein Gehäuse 10 einer Beschichtungsanlage. In dem Gehäuse 10 befindet sich eine Schiene 11, auf der zwei oder mehr Schlitten 12 in einer hier nicht gezeigten schlitzartigen Gehäuseöffnung parallel zu der Werkstückförderrichtung geführt sind. Der Schlitten 12 ist entlang der Gehäuseöffnung in den Richtungen des Doppelpfeils 19 verfahrbar. Auf dem Schlitten 12 kann ein ebenfalls nicht dargestellter, mit dem Schlitten 12 bewegbarer Lackierroboter angebracht sein. Ein Abdeckband 13 verschließt die Gehäuseöffnung und schützt somit die im Gehäuse 10 angeordneten Bauteile vor Verschmutzung durch Beschichtungsmaterial oder vor sonstigen die Bauteile schädigenden Einflüssen von außen. Das Abdeckband 13 ist an seinen beiden Enden z. B. mittels Befestigungseinrichtungen 14, 14' am Gehäuse befestigt, also in seiner Längsrichtung stationär angeordnet. Es kann etwa dieselbe Länge haben wie die abzudeckende Öffnung oder die Schiene 11. Das Band 13 kann z. B. am einen Ende bei der durch eine Umlenkeinrichtung gebildeten Befestigungseinrichtung 14' über eine durch den Pfeil F angedeutete, dem Fachmann bekannte Spanneinrichtung gespannt werden, um eine optimale Abdichtung des Gehäuseinneren gegenüber der Umgebung sicherzustellen. Versorgungseinrichtungen 15 für den Roboter sind durch den Schlitten 12 und unter dem durch Umlenkrollen 16 und 17 angehobenen Abdeckband 13 hindurchgeführt. Auf der Schiene 11 können weitere Schlitten mit weiteren Robotern angeordnet sein.Fig. 1 shows a housing 10 of a coating system. In the housing 10 is a rail 11, are guided on the two or more carriages 12 in a slot-like housing opening, not shown here, parallel to the workpiece conveying direction. The carriage 12 is movable along the housing opening in the directions of the double arrow 19. On the carriage 12, a likewise not shown, with the carriage 12 movable painting robot can be mounted. A cover strip 13 closes the housing opening and thus protects the components arranged in the housing 10 from contamination by coating material or from other influences damaging the components from outside. The cover strip 13 is z at its two ends. B. by means of fastening means 14, 14 'attached to the housing, that is arranged stationary in its longitudinal direction. It may have about the same length as the opening to be covered or the rail 11. The band 13 may, for. B. at one end in the fastening device formed by a deflection device 14 'via a direction indicated by the arrow F, known in the art clamping device are tightened to ensure optimum sealing of the housing interior to the environment. Supply devices 15 for the robot are guided through the carriage 12 and under the cover belt 13 raised by deflection rollers 16 and 17. On the rail 11 more slides can be arranged with other robots.

Fig. 2 zeigt den Schlitten 12 im Detail und den Verlauf des Abdeckbandes 13. Das Abdeckband wird über die untere Umlenkrolle 16 nach oben geführt und damit von der Gehäuseöffnung abgehoben. Die untere Umlenkrolle ist mit ihrer Achse parallel zu der Ebene der abzudeckenden Öffnung quer zu deren Längsrichtung so angeordnet, dass ihr der Öffnung zugewandter unterer Rand in oder in der Nähe der Ebene der Öffnung liegt. Durch die zu der Rolle 16 parallele obere Umlenkrolle 17 wird das Band dann dem Verlauf der Gehäuseöffnung folgend auf einer zweiten, in der von dem abzudeckenden Gehäuseinneren wegweisenden Richtung von der Öffnungsebene beabstandeten Bandebene parallel zur Längsrichtung weitergeführt, bis es schließlich durch eine zweite obere Umlenkrolle 20 und eine zweite untere Umlenkrolle 21 wieder auf die ursprüngliche Bandebene zurückgeführt wird. Somit ist es möglich, dass die Versorgungsleitungen 15 unter dem von der Gehäuseöffnung abgehobenen Bereich des Abdeckbandes 13 aus dem Gehäuseinneren zum Schlitten bzw. der mit diesem verbundenen Beschichtungseinrichtung nachgeführt werden können, wobei gleichzeitig das Abdeckband die Abdeckung der Gehäuseöffnung in seinem nicht von der Gehäuseöffnung abgehobenen Bereich sicherstellt. Befinden sich auf der Schiene 11 mehrere hier nicht dargestellte Schlitten 12, die mit Umlenkrollen 16, 17, 20, und 21 versehen sind und jeweils das Abdeckband 13 anheben bzw. wieder auf der Gehäuseöffnung ablegen, so wird die Gehäuseöffnung auch in dem sich ständig ändernden Bereich zwischen den Schlitten durch das Abdeckband 13 zuverlässig gegen die Umgebung abgedichtet. Statt der vier zueinander parallelen Umlenkrollen 16, 17, 20 und 21 sind auch andere, dem Fachmann bekannte Umlenkmechanismen verwendbar, auch solche, bei denen das Band über nicht rotierende, z. B. teilzylindrische oder stiftartige Umlenkflächen gleitet, obwohl die Umlenkrollen in der Regel zu bevorzugen sind.Fig. 2 shows the carriage 12 in detail and the course of the cover strip 13. The cover strip is guided over the lower guide roller 16 upwards and thus lifted from the housing opening. The lower pulley is arranged with its axis parallel to the plane of the opening to be covered transverse to its longitudinal direction so that its opening facing the lower edge in or near the plane of the opening. By parallel to the roller 16 upper guide roller 17, the tape is then the course of the housing opening on a second, in the direction away from the housing interior to be covered away from the opening plane plane parallel to the longitudinal direction continued, until finally by a second upper guide roller 20th and a second lower pulley 21 is returned to the original belt level. Thus, it is possible that the supply lines 15 can be tracked below the lifted from the housing opening portion of the cover strip 13 from the housing interior to the carriage or associated with this coating device, at the same time the cover the cover of the housing opening in its not lifted from the housing opening Area ensures. Are located on the rail 11 a plurality of carriages 12, not shown here, which are provided with pulleys 16, 17, 20, and 21 and respectively lift the cover 13 and put down again on the housing opening, the housing opening is also in the ever-changing Area between the carriage through the cover strip 13 reliably sealed against the environment. Instead of the four parallel pulleys 16, 17, 20 and 21, other known in the art deflecting mechanisms are used, even those in which the tape on non-rotating, z. B. part-cylindrical or pin-like deflection slides, although the pulleys are usually preferable.

Fig. 3 zeigt eine Konstruktionsmöglichkeit für die Beschichtungsanlage in dem hier betrachteten Bereich mit einem Gehäuse 31, einem auf einer Schienenkonstruktion 36 innerhalb des Gehäuses 31 verfahrbaren Schlitten 32, einem Abdeckband 33, unteren Umlenkrollen 34 und oberen Umlenkrollen 35. Das Band 33 dient zur Abdeckung der bei 38 erkennbaren schlitzartigen Gehäuseöffnung, durch die Versorgungsleitungen 37 z.B. für einen Roboter durchgeführt sind. Unter dem von den unteren Umlenkrollen jeweils abgehobenen Bereich des Abdeckbandes 33 können die Versorgungsleitungen 37 dem Schlitten 32 aus dem Inneren des Gehäuses 31 nachgeführt werden. Die Versorgungsleitungen werden also durch die Lücke zwischen den unteren und oberen Umlenkrollen in den Schlitten geführt. Gleichzeitig dichtet das Abdeckband 33 die Gehäuseöffnung 38 vor und hinter dem Schlitten gegenüber der Umgebung ab, wobei das Band beidseitig dicht auf die Öffnung 38 begrenzenden Flächen einer stationären Verkleidung 39 aufliegt.3 shows a construction option for the coating installation in the area considered here, with a housing 31, a carriage 32 movable on a rail construction 36 within the housing 31, a cover band 33, lower deflection rollers 34 and upper deflection rollers 35. The band 33 serves for covering the recognizable at 38 slot-like housing opening, are performed by the supply lines 37, for example, for a robot. Below that of the lower pulleys each lifted portion of the cover 33, the supply lines 37, the carriage 32 from the interior of the housing 31 are tracked. The supply lines are thus guided through the gap between the lower and upper pulleys in the carriage. At the same time, the cover tape 33 seals the housing opening 38 in front of and behind the carriage relative to the surroundings, the tape resting on both sides tightly on the opening 38 delimiting surfaces of a stationary covering 39.

Das stationäre Abdeckband kann mit seiner Querrichtung sowohl horizontal als auch vertikal oder in beliebigen Schräglagen angeordnet sein, und auch die Längsrichtung des von ihm abgedeckten Schlitzes kann beliebig horizontal, vertikal oder schräg verlaufen. Darüber hinaus kann die Erfindung auch für die Abdeckung gebogener Schlitze, also bei nichtlinearer Verfahrbewegung des Schlittens angewendet werden.The stationary cover strip can be arranged with its transverse direction both horizontally and vertically or in any inclined positions, and also the longitudinal direction of the slot covered by it can run arbitrarily horizontally, vertically or obliquely. In addition, the invention can also be applied to the cover of curved slots, so in non-linear movement of the carriage.
