Description

Die Erfindung betrifft eine Vorrichtung zur Entstaubung von Bedruckstoff in Druckmaschinen sowie eine Flexodruckmaschine mit einer solchen Vorrichtung.The invention relates to a device for dedusting of printing material in Printing machines and a flexographic printing machine with such a device.

Beim Bedrucken von Papier und ähnlichen Bedruckstoffen ist die Oberfläche des bedruckten Papiers in der Regel nicht staubfrei. Vor allem bei hohen Druckgeschwindigkeiten führt dies zu einer schnellen Verschmutzung der Klischees oder Druckplatten, weil die Staubpartikel an den von der Druckfarbe feuchten Klischees haften bleiben und die Rasterungen oder allgemein die tiefer liegenden, nichtdruckenden Teile der Klischees zusetzen, so daß die Druckqualität schon nach relativ kurzer Zeit beeinträchtigt wird. Häufiges Waschen der Klischees führt zu kostspieligen Stillstandszeiten der Druckmaschine.When printing on paper and similar substrates is the surface of the printed paper usually not dust-free. Especially at high printing speeds This leads to a fast contamination of the clichés or printing plates because the dust particles moisten on the ink Clichés stick and the louvres or generally the lower lying, Add non-printing parts of the plates, so that the print quality is affected after a relatively short time. Frequent washing of the clichés leads to costly downtime of the printing press.

Es sind verschiedene Verfahren bekannt, mit denen der Bedruckstoff vor dem eigentlichen Druckvorgang entstaubt werden soll, beispielsweise mechanisches Abbürsten, Absaugen oder elektrostatische Entstaubung. Diese Verfahren erweisen sich jedoch oft als unzureichend. Weiterhin ist es bekannt, den Bedruckstoff mit einem Wischtuch abzuwischen. Da es sich bei diesen Wischtüchern um Verbrauchsmaterial handelt, entstehen jedoch verhältnismäßig hohe Kosten.Various methods are known with which the printing material before the actual printing process to be dedusted, for example, mechanical Brushing, vacuuming or electrostatic dedusting. These procedures prove however, often insufficient. Furthermore, it is known, the substrate wipe with a cloth. Since these wipes are consumables but costs are relatively high.

Vorrichtungen nach dem Oberbegriff des Anspruchs 1, bei denen eine befeuchtete Walze am Bedruckstoff abrollt, sind aus DE-C-237 919 und NL-A-79 03 999 bekannt.Devices according to the preamble of claim 1, in which a moistened Roller rolls on the substrate, are from DE-C-237 919 and NL-A-79 03 999th known.

Aufgabe der Erfindung ist es, eine kostengünstige Vorrichtung anzugeben, die eine wirksame Entstaubung von Bedruckstoffen in einer Druckmaschine ermöglicht.The object of the invention is to provide a cost-effective device, the enables effective dedusting of substrates in a printing press.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Vorrichtung zur Entstaubung von Bedruckstoff in einer Druckmaschine, mit einer Walze, die mit oder ohne Schlupf am Bedruckstoff abrollt, einer Einrichtung zum Befeuchten der Oberfläche der Walze und einer am Umfang dieser Walze angeordneten Vorrichtung zum Entfernen des Staubes von der Walzenoberfläche, bei der die Walze eine Rasterwalze ist, die an ihrer Oberfläche ein Näpfchenraster aufweist, und die Einrichtung zum Befeuchten der Walze eine Kammerrakel ist. This object is achieved by a device for dedusting of printing substrate in a printing machine, with a roller using or rolls without slippage on the substrate, a device for moistening the surface of the roller and a device arranged on the circumference of this roller for removing the dust from the roll surface at which the roll an anilox roller having a cell pattern on its surface, and the means for wetting the roller is a chambered doctor blade.

Bei der Walze handelt es sich um eine Rasterwalze, wie sie in Flexodruckmaschinen als Farbauftragwalze eingesetzt wird. Solche Rasterwalzen weisen an ihrer Oberfläche ein feines Näpfchenraster auf und lassen sich daher in kontrollierter Weise mit Hilfe einer Kammerrakel befeuchten. Diese Rasterwalzen und die zugehörigen Kammerrakeln können baugleich mit den Rasterwalzen und Kammerrakeln sein, die in jedem Farbwerk einer Flexodruckmaschine vorhanden sind. Auf diese Weise läßt sich die Entstaubungsvorrichtung in kostengünstiger Weise mit Standardbauteilen realisieren.The roller is an anilox roller, as in flexographic printing machines is used as an inking roller. Such anilox rollers have on their Surface a fine cell grid on and can therefore be controlled in Moisten the method with the help of a chamber doctor blade. These anilox rolls and the associated chamber doctor blades can be identical to the anilox rollers and Chamber knives, which are present in every inking unit of a flexographic printing machine are. In this way, the dedusting can be in cheaper Realize manner with standard components.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention will become apparent from the dependent claims.

Bei der erfindungsgemäßen Vorrichtung kann die zur Entstaubung dienende Rasterwalze aktiv angetrieben sein. Wenn die Walze eine Hohlwalze ist und/oder einen relativ kleinen Durchmesser aufweist, kann ihr Trägheitsmoment jedoch so gering sein, daß es möglich ist, die Walze lediglich passiv mitlaufen zu lassen. In beiden Fällen ist es möglich, durch gezielte Einstellung eines Schlupfes zwischen der Walzenoberfläche und dem Bedruckstoff die Entstaubungswirkung zu erhöhen. Bei einer mitlaufenden Walze kann der Schlupf beispielsweise durch den Bremseffekt erreicht werden, der unvermeidlich beim Abrakeln der Walzenoberfläche auftritt.In the apparatus according to the invention can serve for dedusting Anilox roller be actively driven. When the roll is a hollow roll and / or has a relatively small diameter, however, its moment of inertia can be so small that it is possible to let the roller passively pass only. In both cases, it is possible, by deliberately setting a slip between the roller surface and the printing material to the dedusting effect increase. In a revolving roller, the slip can, for example by the braking effect is achieved, which is inevitable when doctoring the roll surface occurs.

Bei der zum Befeuchten der Walze eingesetzten Flüssigkeit kann es sich um Wasser handeln, dem wahlweise geeignete Additive, z. B. Tenside, zugesetzt sein können, um die Adhäsionswirkung zu verbessern und/oder das Entfernen des Staubes von der Walzenoberfläche zu erleichtern.The liquid used to wet the roller may be Water, the optional suitable additives, eg. As surfactants may be added to improve the adhesion effect and / or the removal of the To facilitate dust from the roll surface.

Im folgenden werden Ausführungsbeispiele der Erfindung anhand der Zeichnungen näher erläutert.In the following, embodiments of the invention with reference to the drawings explained in more detail.

FIG. 2
a schematic representation of a modified embodiment of the dedusting device.

Figur 1 zeigt einen Gegendruckzylinder 10 einer Flexodruckmaschine, der von dem Bedruckstoff 12, beispielsweise einer Papierbahn, umschlungen ist. Weiterhin ist eines von mehreren Farbwerken 14 gezeigt, die am Umfang des Gegendruckzylinders 10 angeordnet sind und jeweils einen Druckzylinder 16, eine Auftragwalze 18 und eine Kammerrakel 20 zum Einfärben der Auftragwalze umfassen.FIG. 1 shows a counter-pressure cylinder 10 of a flexographic printing machine, which is produced by the printing substrate 12, for example a paper web, is looped around. Farther one of several inking units 14 is shown at the periphery of the impression cylinder 10 are arranged and in each case a pressure cylinder 16, a Application roller 18 and a chamber doctor blade 20 for coloring the applicator roll include.

Bevor der Bedruckstoff 12 den Gegendruckzylinder 10 erreicht, läuft er über eine Entstaubungsvorrichtung 22, die in Figur 1 aus Gründen der Deutlichkeit übertrieben groß dargestellt ist. Diese Entstaubungsvorrichtung 22 weist eine Walze 24 auf. Der Bedruckstoff 12 läuft unter leichter Umlenkung über die Umfangsfläche der Walze 24, deren Umfangsgeschwindigkeit annährend mit der Bahngeschwindigkeit des Bedruckstoffs übereinstimmt. Da die Zugspannung des Bedruckstoffes in bekannter Weise geregelt wird, läuft der Bedruckstoff mit kontrollierter Andruckkraft über die Walze 24.Before the printing material 12 reaches the impression cylinder 10, it runs over a dedusting device 22, which in Figure 1 for clarity is shown exaggeratedly large. This dedusting device 22 has a Roll 24 up. The printing material 12 runs with slight deflection over the peripheral surface the roller 24, whose peripheral speed approximately with the Web speed of the substrate matches. Because the tension the printing material is controlled in a known manner, the printing material runs with Controlled pressure force on the roller 24.

Bei der Walze 24 handelt es sich um eine der Rasterwalze 18 entsprechende Rasterwalze, die auf ihrer Oberfläche ein feines Raster von Näpfchen 26 aufweist, das in Figur 1 auf einem Teil des Umfangs dieser Walze übertrieben dargestellt ist. An den Umfang der Walze 24 ist auf der dem Bedruckstoff 12 entgegengesetzten Seite eine an sich bekannte Kammerrakel 28 angestellt, die hier jedoch nicht zum Einfärben, sondern zum Befeuchten der Walze 24 mit Wasser dient. Beim Durchlauf der Oberfläche der Walze 24 durch die Kammerrakel 28 werden geringe Wassermengen in den Näpfchen 26 zurückgehalten, so daß die Walze 24 in kontrollierter Weise befeuchtet wird. Die so befeuchtete Walzenoberfläche kommt dann mit dem Bedruckstoff 12 in Berührung, so daß der an dem Bedruckstoff haftende Staub aufgrund der größeren Adhäsionswirkung der feuchten Walze 24 auf die Walzenoberfläche übertragen wird.The roller 24 is an anilox roller corresponding to the anilox roller 18, which has a fine grid of wells 26 on its surface, that exaggerated in Figure 1 on a part of the circumference of this roller is. At the periphery of the roller 24 is opposite to the substrate 12 Side employed a known chamber doctor blade 28, but here not for coloring, but for wetting the roller 24 is used with water. As the surface of the roller 24 passes through the chambered doctor blade 28 small amounts of water in the wells 26 retained so that the roller 24th is moistened in a controlled manner. The so moistened roller surface Then comes with the substrate 12 in contact, so that the s.den printing material Adhesive dust due to the greater adhesion of the moist Roller 24 is transferred to the roll surface.

In Rotationsrichtung hinter der Berührungszone zwischen dem Bedruckstoff 12 und der Walze 24 ist am Umfang der Walze 24 ein Rakelmesser 30 angeordnet, mit dem der an der Walzenoberfläche haftende Staub abgerakelt oder abgeschabt wird. Der so von der Walze 24 entfernte Staub fällt in eine Auffangwanne 32. Die Kammerrakel 28 wird über einen Zulauf 34 und einen Rücklauf 36 fortlaufend oder intervallweise mit Reinwasser durchspült. Im gezeigten Beispiel ist der Zulauf 34 als verlängerte Düse ausgebildet, die innerhalb der Rakelkammer zu einer Breitschlitzdüse verbreitert und auf die Umfangsfläche der Walze 24 gerichtet ist, so daß die Walze 24 auf ganzer Breite mit einem aus der Düse austretenden Wasserstrahl gewaschen wird. Hierdurch werden auf der Walzenoberfläche und/oder in den Näpfchen haftende Staubpartikel wirksam entfernt, so daß sie über den Rücklauf 36 mit abgeführt werden. Wahlweise kann das Entfernen der Staubpartikel von der Walze 24 auch allein mit Hilfe der Kammerrakel 28 bewirkt werden, so daß auf das Rakelmesser 30 verzichtet werden kann.In the direction of rotation behind the contact zone between the substrate 12th and the roller 24 is arranged on the circumference of the roller 24, a doctor blade 30, by means of which the dust adhering to the roll surface is scraped off or scraped off becomes. The thus removed from the roller 24 dust falls into a drip tray 32nd The chamber doctor blade 28 is continuously connected via an inlet 34 and a return 36 or rinsed with pure water at intervals. In the example shown is the inlet 34 is formed as an elongated nozzle, which is within the doctoring chamber widened to a slot die and directed to the peripheral surface of the roller 24 is, so that the roller 24 across the entire width with a leaving the nozzle Water jet is washed. This will be on the roll surface and / or effectively removes dust particles adhering in the cups, then that they are discharged via the return 36 with. Optionally, the removal can the dust particles from the roller 24 alone with the help of the chamber doctor blade 28 are effected, so that can be dispensed with the doctor blade 30.

Figur 2 zeigt eine Entstaubungsvorrichtung 38, die ähnlich wie die Entstaubungsvorrichtung 22 gemäß Figur 1 eine Rasterwalze 24 und eine Kammerrakel 28 aufweist. Der Bedruckstoff 12 läuft hier jedoch unter leichter Ablenkung über eine Gegendruckwalze 40, die mit der Walze 24 einen Walzenspalt bildet. Der Druck in diesem Walzenspalt ist in bekannter Weise einstellbar.FIG. 2 shows a dedusting device 38, which is similar to the dedusting device 22 according to FIG. 1, an anilox roller 24 and a chamber doctor blade 28 has. However, the printing substrate 12 runs over here with slight deflection a platen roller 40 which forms a nip with the roller 24. Of the Pressure in this nip is adjustable in a known manner.

In dem in Figur 2 gezeigten Beispiel rotiert die Walze 24 im Gegenuhrzeigersinn, und der Bedruckstoff läuft von unten nach oben durch den Walzenspalt. Wiederum ist in Rationsrichtung hinter der Berührungszone zwischen dem Bedruckstoff 12 und der Walze 24 ein Rakelmesser 30 angeordnet, mit dem der Staub von der Walzenoberfläche entfernt wird. Unterstützend ist hier eine Saugdüse 42 vorgesehen, die den mit Hilfe des Rakelmessers 30 von der Walzenoberfläche abgelösten Staub absaugt. Aufgrund der Befeuchtung der Walze 24 kann sich am Rakelmesser 30 ein "Kuchen" aus feuchtem Staub ansammeln, der dann mit Hilfe der Saugdüse 42 entfernt wird. Die Saugdüse 42 kann eine Breitschlitzdüse sein. Wahlweise kann es sich jedoch auch um ein Düsenrohr handeln, das in Axialrichtung der Walze 24 hin und her bewegt wird, so daß der Staub, der sich vor der Schneide des Rakelmessers 30 sammelt, periodisch abgesaugt wird.In the example shown in FIG. 2, the roller 24 rotates counterclockwise, and the substrate runs from bottom to top through the nip. In turn is in ration direction behind the contact zone between the substrate 12 and the roller 24, a doctor blade 30 is arranged, with which the Dust is removed from the roll surface. Supporting here is one Suction nozzle 42 is provided, which by means of the doctor blade 30 from the roll surface vacuuming detached dust. Due to the moistening of the roller 24, a "cake" of wet dust can accumulate on the doctor blade 30, which is then removed by means of the suction nozzle 42. The suction nozzle 42 may be a Be slot die. Optionally, however, it may also be a nozzle tube act, which is moved in the axial direction of the roller 24 back and forth, so that the Dust, which collects in front of the cutting edge of the doctor blade 30, periodically sucked becomes.
