Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Lackieren oder Beschichten eines Bogens mittels einer rotierenden, mit einer Gegendruckwalze zusammenwirkenden Auftragswalze, an welcher der Bogen geführt und beschichtet wird, sowie mit einer im Walzenspalt angeordneten Abnahmevorrichtung zum Abziehen der Bogen von der Auftragswalze.The invention relates to a device for painting or coating a sheet by means of a rotating application roller which interacts with a counter-pressure roller, on which the sheet is guided and coated, and with a removal device arranged in the nip for removing the sheets from the application roller.

Bei einer aus der Patentschrift DE 30 17 271 C2 bekannt ge­wordenen Beschichtungsvorrichtung der vorstehend beschriebenen Art besteht die Abnahme aus einer parallel zu den Drehachsen der Auftrags- und der Gegenwalze angeordneten Druckluftdüse, die die Bogenkante mit einem gesteuerten Druckluftstoß beauf­schlagt, um so das Ablösen von der Auftragswalze und den an­schließenden Abtransport über Transportbänder od.dgl. sicher­zustellen. Diese bekannte Abnahmevorrichtung hat jedoch den Nachteil, daß nur geringe Geschwindigkeiten möglich sind, da bei zu hohen Laufgeschwindigkeiten der Bögen ein zuverlässi­ges Erfassen und Ablösen der Bogenvorderkante durch einen Druckluftstoß nicht gewährleistet ist. Darüber hinaus ergibt sich eine sehr starke Verschmutzung der Anlage durch hohen Luftdruck und daher eine Verwirbelung der Beschichtungsmittel in der Anlage. Dies wiederum führt zu einer weiteren Verringe­rung der Produktionsleistung durch ständige material- und systembedingte Maschinenstopps mit langen Reinigungszeiten.In a coating device of the type described above, which has become known from the patent DE 30 17 271 C2, the removal consists of a compressed air nozzle which is arranged parallel to the axes of rotation of the application roller and the counter roller and which acts on the sheet edge with a controlled compressed air pulse, in order thus to detach it from the Application roller and the subsequent removal via conveyor belts or the like. ensure. However, this known removal device has the disadvantage that only low speeds are possible, since if the sheet speeds are too high, reliable detection and detachment of the sheet leading edge by a blast of compressed air is not guaranteed. In addition, there is very heavy contamination of the system due to high air pressure and therefore swirling of the coating agents in the system. This in turn leads to a further reduction in production output due to constant material and system-related machine stops with long cleaning times.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vor­richtung der eingangs genannten Art so auszugestalten, daß - unter Beibehaltung der greiferlosen Abnahme der Bogen von der Auftragswalze - hohe Verarbeitungsgeschwindigkeiten in Verbindung mit einem störungsfreien Betrieb ohne zusätzliche Verschmutzung der Anlage möglich sind.The invention is therefore based on the object of designing a device of the type mentioned in such a way that - while maintaining the gripper-free removal of the sheets from the application roller - high processing speeds in connection with trouble-free operation without additional contamination of the system are possible.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Abnahmevorrichtung mit einer Saugquelle verbundene rotieren­de Saugwalzen umfaßt, die bevorzugt automatisch über Funktions­taster der Anlage gesteuert, an die Auftragswalze an- oder abstellbar sowie ausschaltbar sind.To achieve this object, it is provided according to the invention that the take-off device comprises rotating suction rolls connected to a suction source, which are preferably controlled automatically via function keys of the system, can be switched on or off and switched off on the application roll.

Durch die erfindungsgemäßen Saugwalzen werden die Bogenvorder­kanten der an der Auftragswalze haftenden beschichteten Bogen unmittelbar nach dem Austritt aus dem Spalt zwischen Auftrags­walze und Gegendruckwalze zuverlässig erfaßt und von der Auf­tragswalze abgezogen, wobei neben dem reinen Abziehen der Vorderkante auch für einen exakten kontrollierten Abtransport durch die rotierenden Saugwalzen gesorgt ist, so daß die Bogen anschließend auf die eigentliche Abtransportvorrichtung, bei­spielsweise übliche Transportbänder, abgegeben werden können. Diese Transportbänder, in deren Zwischenabständen im vorderen Umlenkbereich die erfindungsgemäßen Saugwalzen angeordnet werden können, sollen ihrerseits bevorzugt als - an sich be­kannte - Saugbänder ausgebildet sein.By means of the suction rollers according to the invention, the sheet leading edges of the coated sheets adhering to the application roller are reliably detected immediately after they emerge from the nip between the application roller and the counter-pressure roller and are pulled off the application roller, and besides the mere pulling off of the leading edge also for an exactly controlled removal by the rotating suction rollers is taken care of, so that the sheets can then be delivered to the actual removal device, for example conventional conveyor belts. These conveyor belts, at the intervals between which the suction rolls according to the invention can be arranged in the front deflection area, should in turn preferably be designed as suction belts, known per se.

Um gezielt nur dort zu saugen, wo das eigentliche Ablösen der Bogen von der Auftragswalze stattfinden soll und andererseits nicht eine unnötig starke Auslegung der Saugquelle in Kauf nehmen zu müssen, wenn auch aus anderen Umgebungsbereichen Luft mit eingesaugt werden kann, ist in weiterer Ausgestaltung der Erfindung vorgesehen, daß die Saugwalzen in Kassettenbauweise ausgebildet sind, wobei rotierend gelochte Hohlwalzen dichtend an einer innenliegenden offenen Saugkammer gleiten. Die Öff­nung der Saugkammer, d.h. der eigentliche Saugbereich in Um­ fangsrichtung der Walzen wird dabei zweckmäßigerweise in Abhängigkeit vom Durchmesser der Auftragswalze gewählt, so daß zwar im eigentlichen Anlagebereich der Saugwalzen und der Auftragswalzen ein Ansaugen stattfindet, nicht aber in den Bereichen, in denen die Walzen doch relativ weit voneinander getrennt sind, so daß dann auch die Saugwirkung nicht mehr selektiv und gezielt auf den zwischen der Auftragswalze und den Saugwalzen verlaufenden abzunehmenden Bogen gerichtet ist.In order to specifically suck only where the actual detachment of the sheets from the application roller is to take place and on the other hand not to have to accept an unnecessarily strong design of the suction source, even if air can also be sucked in from other surrounding areas, is a further embodiment of the invention provided that the suction rolls are designed in a cassette design, rotating perforated hollow rolls sealingly sliding on an internal open suction chamber. The opening of the suction chamber, ie the actual suction area in um The direction of the rollers is expediently chosen depending on the diameter of the application roller, so that suction takes place in the actual contact area of the suction rollers and the application rollers, but not in the areas in which the rollers are relatively far apart, so that then the suction effect is no longer selectively and specifically directed to the sheet to be removed running between the application roller and the suction rollers.

Dabei hat es sich als besonders zweckmäßige Maßnahme erwiesen, wenn die Saugstrecken der Saugwalzen und der Saugbänder einan­der überlappen, so daß durchgehend und ohne Unterbrechung von der Kontaktstelle der Saugwalzen mit der Auftragswalze und damit mit dem zwischen den Walzen verlaufenden abzulösenden Bogen bis zum endgültigen Abtransport nach vollständiger Trennung der Bogen von der Beschichtungsvorrichtung diese in Saugkontakt mit der Abnahmevorrichtung verbleiben. Dadurch lassen sich Störungen bei der Abnahme und beim Abtransport der Bogen be­sonders gering halten.It has proven to be a particularly expedient measure if the suction paths of the suction rolls and the suction belts overlap one another, so that continuously and without interruption from the contact point of the suction rolls with the application roll and thus with the sheet to be detached running between the rolls until the final removal complete separation of the sheets from the coating device, these remain in suction contact with the removal device. As a result, disruptions in the removal and removal of the sheets can be kept particularly low.

Eine weitere Verbesserung der Bogenabnahme und des Weiter­gebens an die Transportbänder läßt sich gemäß einem weiteren Merkmal der Erfindung dadurch erzielen, daß die Saugwalzen mit einem Überzug mit hohem Reibungskoeffizienten, insbesondere Gummi, versehen sind.A further improvement in sheet removal and transfer to the conveyor belts can be achieved according to a further feature of the invention in that the suction rolls are provided with a coating with a high coefficient of friction, in particular rubber.

Durch eine voneinander unabhängige Anschließbarkeit der Saug­walzen an die Saugquelle läßt sich - ohne Umbau der Vorrichtung - eine sehr einfache Anpassung an geänderte Bogenformate erzie­len. Darüber hinaus kann jedoch in Weiterbildung der Erfindung auch vorgesehen sein, daß die einzelnen Saugwalzen einfach auswechselbar bzw. entfernbar montiert sind, beispielsweise mit einfachen Schnellverschlüssen, so daß bei einem Format­wechsel der Anlage eine zweckentsprechende Breite der Saugwalzen­anordnung einstellbar ist.Because the suction rolls can be connected to the suction source independently of one another, a very simple adaptation to changed sheet formats can be achieved without having to convert the device. In addition, however, in a further development of the invention it can also be provided that the individual suction rolls are easily exchangeable or removable, for example with simple quick-release fasteners, so that a suitable width of the suction roll arrangement can be set when the format is changed.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Aus­führungsbeispiels sowie anhand der Zeichnung:

  • Fig. 1 eine schematische Seitenansicht einer erfindungsgemäßen Beschichtungsvorrichtung mit einer saugwalzenumfassen­den Bogenabnahmevorrichtung,
  • Fig. 2 eine Aufsicht auf die Abnahmevorrichtung zum Abziehen der Bogen von der Auftragswalze,
  • Fig. 3 einen versetzten Querschnitt längs der Linie III-III in Fig. 4 durch eine Saugwalze und
  • Fig. 4 einen axialen Längsschnitt durch eine der Saugwalzen.
Further advantages, features and details of the invention result from the following description of an exemplary embodiment and from the drawing:
  • 1 is a schematic side view of a coating device according to the invention with a sheet removal device comprising suction rolls,
  • 2 is a plan view of the take-off device for pulling the sheets from the application roller,
  • Fig. 3 shows an offset cross section along the line III-III in Fig. 4 by a suction roll and
  • Fig. 4 is an axial longitudinal section through one of the suction rolls.

In Fig. 1 ist lediglich schematisch die eigentliche Beschichtungs­vorrichtung mit einer Farbwalze 1, einer Zwischenwalze 2, der Auftragswalze 4 und der Gegendruckwalze 5 zu erkennen, wobei die längs der Bahn des Pfeils 6 eingeführten Bogen 7 zwischen der Gegendruckwalze 5 und der Auftragswalze 4 verlaufen. Die Abnahmevorrichtung für die Bogen umfaßt in an sich bekannter Weise Saugbänder 8 mit Saugöffnungen 9, die über Saugkästen 10 angeordnet verlaufen. Die auf den Saugbändern 8 aufliegenden Bogen 7 werden somit durch Saugkraft an den Saugbändern ge­halten, so daß auch bei hohen Verarbeitungs- und Transportge­schwindigkeiten ein Verrutschen der Bogen und eine Störung des Abtransports sicher verhindert ist.In Fig. 1, the actual coating device with an inking roller 1, an intermediate roller 2, the application roller 4 and the counter-pressure roller 5 can only be seen schematically, the sheets 7 introduced along the path of the arrow 6 running between the counter-pressure roller 5 and the application roller 4. The take-off device for the sheets comprises, in a manner known per se, suction belts 8 with suction openings 9 which are arranged above suction boxes 10. The sheets 7 resting on the suction belts 8 are thus held by suction on the suction belts, so that slipping of the sheets and a disturbance of the removal are reliably prevented even at high processing and transport speeds.

Erfindungsgemäß sind im vorderen Umlenkbereich der Transport­bänder 8 zwischen diesen Saugwalzen 11 angeordnet, die durch - im einzelnen nicht dargestellte, weil bei derartigen Be­schichtungsvorrichtungen an sich bekannte - Stellvorrichtungen an die Auftragswalze 4 an- oder abstellbar sowie ausschaltbar sind, wobei das An- und Abstellen bevorzugt automatisch über Funktionstaster der Anlage steuerbar sein kann. Die in den Figuren 3 und 4 näher dargestellten Saugwalzen 11 umfassen gelochte Hohlwalzen 12, die dichtend an einer innenliegenden offenen Saugkammer 13 gleiten. Durch dieses Gleiten, das be­vorzugt auf den Bereich der Saugkammer 13 beschränkt ist, da ja nur dort eine Abdichtung zwischen dem die Saugkammer 13 aufweisenden Kern 14 und der Hohlwalze 12 erforderlich ist, er­folgt unabhängig davon, daß die Hohlwalze 12 auf ihrem gesamten Umfang gelocht ist, eine Saugwirkung nur in einem Bereich, der dem Querschnitt der Saugkammer 13 entspricht. Die Kernabschnitte 14, 15, die in die Hohlwalze 12 einragen, sind fest an einem Kasten 16 montiert, der die Verbindungsleitung 17 zur nicht dargestellten Saugquelle enthält. Auf der gegenüberliegenden Seite ist die gelochte Hohlwalze 11, die auf einer Achse 18 gelagert ist, über ein in Fig. 4 nur angedeutetes Zahnradge­triebe mit einer Welle 19 verbunden, die ihrerseits in Ver­bindung mit der Antriebswelle 20 der Transportbänder 8 steht. Ausgehend von ein und der gleichen Antriebsvorrichtung läßt sich damit erreichen, daß die Umfangsgeschwindigkeit der Saug­walzen der Laufgeschwindigkeit der Transportbänder 8 angepaßt ist.According to the invention, in the front deflection area of the conveyor belts 8 are arranged between these suction rollers 11, which can be switched on or off and off on the application roller 4 by adjusting devices (not shown in detail because such coating devices are known per se), with the switching on and off preferred can be controlled automatically via the function button of the system. The suction rolls 11 shown in more detail in FIGS. 3 and 4 comprise perforated hollow rolls 12 which seal against an inner one slide open suction chamber 13. By this sliding, which is preferably limited to the area of the suction chamber 13, since only there is a seal between the core 14 having the suction chamber 13 and the hollow roller 12 is required, regardless of the fact that the hollow roller 12 is perforated over its entire circumference , A suction effect only in an area that corresponds to the cross section of the suction chamber 13. The core sections 14, 15 which protrude into the hollow roller 12 are fixedly mounted on a box 16 which contains the connecting line 17 to the suction source, not shown. On the opposite side, the perforated hollow roller 11, which is mounted on an axis 18, is connected to a shaft 19 via a gear transmission, which is only indicated in FIG. 4 and which in turn is connected to the drive shaft 20 of the conveyor belts 8. Starting from one and the same drive device, it can be achieved that the peripheral speed of the suction rolls is adapted to the running speed of the conveyor belts 8.

Mit 21 und 22 sind die vorderen und hinteren Umlenkrollen der Transportbänder 8 und mit 24 die Spannrollen für die Transport­bänder 8 bezeichnet, während bei 23 in den Figuren 3 und 4 Querträger bezeichnet sind, an denen die Kästen 16 mit den Verbindungsleitungen 17 zur Saugquelle und damit auch die Saugkästen selbst gehaltert sind. Diese Querträger 23 sind der übersichtlichkeit halber in Fig. 2 nicht mit eingezeichnet.21 and 22 denote the front and rear deflection rollers of the conveyor belts 8 and 24 the tensioning rollers for the conveyor belts 8, while at 23 in FIGS. 3 and 4 crossbeams are designated, on which the boxes 16 with the connecting lines 17 to the suction source and thus the suction boxes themselves are held. For the sake of clarity, these cross members 23 are not shown in FIG. 2.

Die Saugwalzen 11 und die Saugbänder 8 erhalten ihren Antrieb jeweils über die Welle 19, und zwar einmal über die im einzelnen nicht bezeichneten Zahngetriebe und zum anderen über Trans­missionsriemen 25.The suction rollers 11 and the suction belts 8 each receive their drive via the shaft 19, specifically once via the toothed gears not specifically identified and secondly via transmission belts 25.
