Abstract

The invention concerns an ink duct (1) for a rotary printing press, wherein all or some of the surfaces (19, 21) are permanently coated with a substance (46) which has low surface energy of between 10 and 60 mN/m. As well as enabling the ink duct to be cleaned easily, the blending of the printing ink is improved owing to the reduced frictional resistance of the coated parts (6, 7, 13, 14), which in turn leads to more uniform use of the ink-metering roller (4).

FarbkastenPaint box
Die Erfindung betrifft einen Farbkasten für ein Farbwerk einer Rotationsdruckmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to an ink fountain for an inking unit of a rotary printing press according to the preamble of claim 1.
Der Erfindung Liegt die Aufgabe zugrunde, einen Farbkasten zu schaffen.The invention has for its object to provide a paint box.
Diese Aufgabe wird e rf i ndungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.This object is achieved according to the features of the characterizing part of claim 1.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß infolge der Beschichtung der Innenseite des Farbkastens sowie der Dosierelemente die Oberflächenenergie und somit die Oberflächenspannung und somit der Reibwiderstand zu Druckfarbe gegenüber allen Flächen, die mit Druckfarbe in Berührung kommen, stark reduziert wurde. Nicht nur, daß eine Reinigung der mit Druckfarbe in Verbindung kommenden Teile ohne Aufwand möglich ist, kann sich infolge des verringerten Reibwiderstandes der beschichteten Teile die Druckfarbe besser durchmischen. Außerdem wird eine sog. "Druckfarben-Rollenbildung" im Farbkasten begünstigt, was wiederum eine gleichmäßigere Benetzung der Fa rbdos i e rwa Ize zur Folge hat. Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben. Es zeigen:The advantages that can be achieved with the invention are, in particular, that as a result of the coating on the inside of the ink fountain and the metering elements, the surface energy and thus the surface tension and thus the frictional resistance to printing ink have been greatly reduced compared to all surfaces that come into contact with printing ink. Not only is it possible to clean the parts that come into contact with the printing ink without effort, the printing ink can mix better as a result of the reduced frictional resistance of the coated parts. In addition, a so-called "printing ink roll formation" in the ink fountain is promoted, which in turn results in a more uniform wetting of the colors. Embodiments of the invention are shown in the drawing and are described in more detail below. Show it:

Der Farbkasten 1 besteht aus zwei sich in achsparalleler Richtung der Fa rbdos i e rwa Ize 4 erstreckenden, voneinander beabs t andet en linken 6 und rechten Seitenwänden 7. Je nach vorgesehener Sc hwenk ri chtung ist die linke 6 und/oder die rechte Seitenwand 7 in ausreichender Höhe über die gesamte Breite des Farbkastens 1 erstreckend nach innen abgewinkelt.The ink fountain 1 consists of two left 6 and right side walls 7, which extend in the axis-parallel direction of the colors 4 and are spaced apart from one another, depending on the intended pivoting direction the left 6 and / or the right side wall 7 angled inward to a sufficient height over the entire width of the ink fountain 1.
Die rechte/linke Seitenwand 7, 6 verläuft von ihrer oberen Kante 10 nach unten, so daß sich die lichte Weite des Farbkastens 1 z. B. etwa bis zur halben Höhe des Farbkastens 1 vergrößert und anschließend sich im darunterliegenden Teil wieder verengt. Hierdurch wird in der Entleerstellung B des Farbkastens 1 eine t i e f s 11 i egende Rinne 44 gebildet, in welche die Druckfarbe 22 einläuft und von ihr aufgenommen wird. Die Seitenwände 6, 7 erstrecken sich (Arbe i t s s t e l lung A) von einer oberen Kante 10 in Richtung ihrer der Fa rbdos i e rwa lze 4 zugewandten unteren Rakelmontagefläche 8; 9, an welcher Rakelblätter 11; 12 mittels Klemmleisten 13 bzw. 14 gehalten sind.The right / left side wall 7, 6 runs from its upper edge 10 downward, so that the clear width of the ink fountain 1 z. B. enlarged to about half the height of the ink fountain 1 and then narrowed again in the part below. In this way, in the emptying position B of the ink fountain 1, a channel 44 is formed, into which the printing ink 22 runs and is received by it. The side walls 6, 7 extend (working position A) from an upper edge 10 in the direction of their lower squeegee mounting surface 8 facing the ink roller 4; 9, on which doctor blades 11; 12 are held by means of terminal strips 13 and 14, respectively.
An den Enden der Seitenwände 6; 7 sind beidseitig Stirnwände 15; 17 angebracht. Jede Stirnwand 15; 17 ist mit ihrer der Fa rbdos i e rwa lze 4 zugewandten Seite 18 der Kontur der Mantelfläche 2 angepaßt. In seiner Entleerstellung B kann der Farbkasten 1 z. B. um den Winkel Beta = 70° bis 110° um die Rotationsachse 5 der Fa rbdos i e rwa lze 4 verschwenkt werden. Die Rakelblätter 11 und 12 bleiben dabei in Kontakt mit der Oberfläche 2 der Fa rbdos i e rwa lze 4. Der Farbkasten 1 ist - in seiner Arbe i t s st e l lung A gesehen - oben offen. Der Farbkasten 1 kann an einer Traverse 20 z . B. mittels seiner Seitenwand 6 an den Seitengestellen der Maschine befestigt sein.At the ends of the side walls 6; 7 are end walls 15 on both sides; 17 attached. Each end wall 15; 17 is adapted to the contour of the lateral surface 2 with its side 18 facing the fa rbdos ie rwa lze 4. In its emptying position B, the ink fountain 1 z. B. by the angle Beta = 70 ° to 110 ° about the axis of rotation 5 of the Fa rbdos ie rwa lze 4 are pivoted. The doctor blades 11 and 12 remain in contact with the surface 2 of the ink roller 4. The ink fountain 1 is - seen in its working position A - open at the top. The ink fountain 1 can on a cross member 20 z. B. be attached by means of its side wall 6 to the side frames of the machine.
Bei einem weiteren Aus f üh rungsbe i spi e l sind beide Enden der Traverse 20 des Farbkastens 1 an je einem ersten Ende 28 bzw. 29 eines Schwenkarmes 26 bzw. 27 befestigt. Die zweiten Enden 31; 32 der Schwenkarme 26; 27 sind jeweils schwenkbar auf einer se i t enges te 11 fest en Lagerbuchse 33; 34 gelagert. Jede Lagerbuchse 33, 34 nimmt jeweils über ein Wälzlager 36; 37 einen Achszapfen 38; 39 der Fa rbdos i e rwa lze 4 auf. Durch die eben beschriebenen Maßnahmen kann der Farbkasten 1 um die Rotationsachse 5 der Fa rbdos i e rwa lze 4 geschwenkt werden.In a further embodiment, both ends of the cross member 20 of the ink fountain 1 are each attached to a first end 28 or 29 of a swivel arm 26 or 27. The second ends 31; 32 of the swivel arms 26; 27 are each pivotable on a narrow 11 fixed bearing bush 33; 34 stored. Each bearing bush 33, 34 takes over a roller bearing 36; 37 an axle 38; 39 of Fa rbdos i e rwa lze 4. With the measures just described, the ink fountain 1 can be pivoted about the axis of rotation 5 of the roller 4.
In seiner oberen, d. h. A rbe i t s s t e l lung A wird der Farbkasten 1 direkt oder indirekt über die an den Schwenkarmen 26, 27 befestigte Traverse 20 an einem se i tenges t e 11 f est en Anschlag 41 bewegt und dort verriegelt oder mittels Schrauben 42 festgehalten. Der liegende Farbkasten 1 kann von seiner oben l i egenden Arbe i ts st e l lung A nach seiner Entriegelung seitlich in eine Entleerstellung B geschwenkt werden. Die Rakelblätter 11 und 12 bleiben dabei in Berührung mit dem Umfang der Fa rbdos i e rwa lze 4. Der Schwenkwinkel Beta des Farbkastens 1 kann zwischen 70 und 110° liegen. Die Schwenkbewegung des Farbkastens 1 nach unten wird z. B. durch einen sei tenges te l l festen Anschlag 43 begrenzt. An dem liegt dann die rechte Seitenwand 7 des Farbkastens 1 an und wird an diesem festgehalten bzw. verriegelt.In its upper, ie working position, the ink fountain 1 is moved directly or indirectly via the cross member 20 fastened to the swivel arms 26, 27 on a side-tight 11 fixed stop 41 and locked there or held in place by means of screws 42. The lying ink fountain 1 can be pivoted laterally from its working position A above after its unlocking into an emptying position B. The doctor blades 11 and 12 remain in contact with the circumference of the ink roller 4. The swivel angle beta of the ink fountain 1 can be between 70 and 110 °. The pivotal movement of the ink fountain 1 downward z. B. limited by a be tenges te ll fixed stop 43. On this is then the right side wall 7 of the ink fountain 1 and is held or locked to this.
Dabei sammelt sich die Druckfarbe 22 in einer nach oben hin offenen Rinne 44 der Seitenwand 7, welche sich nunmehr in horizontaler Lage befindet.The ink 22 collects in an upwardly open channel 44 of the side wall 7, which is now in a horizontal position.
Der Farbkasten 1 kann, insbesondere in der horizontalen Entleerstellung B, vorzugsweise aus der Maschine leicht herausnehmbar sein, d. h. von der Traverse 20 lösbar ausgebildet sein. Dazu kann z. B. die linke Seitenwand 6 außer mittels einer Linearführung in der Traverse 20 führbar und arretierbar ausgebildet sein.The ink fountain 1, particularly in the horizontal emptying position B, can preferably be easily removed from the machine, i. H. be designed to be detachable from the crossmember 20. For this, e.g. B. the left side wall 6 can be guided and locked except by means of a linear guide in the crossmember 20.
Dadurch, daß der Farbkasten 1 aus der Maschine entfernt ist, kann sowohl der Farbkasten 1 wie auch die Fa rbdos i e rwa lze 4 leicht gereinigt werden.Because the ink fountain 1 is removed from the machine, both the ink fountain 1 and the color robs 4 can be easily cleaned.
Die Erreichbarkeit des Ve rs chwenkens des Farbkastens 1 ist nicht auf die eben beschriebenen Mittel beschränkt. Es ist ebenso auch möglich, den Farbkasten 1 mit anderen technischen Mitteln von Stellung A nach Stellung B und wieder zurück zu ve r schwenken .The accessibility of the pivoting of the ink fountain 1 is not limited to the means just described. It is also possible to swivel the ink fountain 1 by other technical means from position A to position B and back again.
So könnten z. B. die Stirnwände 15; 17 jeweils mit Stehbolzen versehen sein, wobei die Stehbolzen in sei tenges te l l festen bogenförmigen Führungen geführt we rden . Die Fa rbdos i e re lemente 11, 12 sind vorzugsweise als Rakelblätter ausgeführt, sie können aber auch Farbmesser, Fa rbmesse r lame l len sein. Sie sind an der Unterseite des Farbkastens 1 angeordnet und befestigt. Die Rakelblätter dienen als Arbeitsrakel 12 und/oder als Schließrakel 11.For example, B. the end walls 15; 17 each be provided with stud bolts, the stud bolts being guided in rigid, arched guides. The ink doses 11, 12 are preferably designed as doctor blades, but they can also be ink knives, ink masks. They are arranged and fastened on the underside of the ink fountain 1. The doctor blades serve as a working doctor blade 12 and / or as a closing doctor blade 11.
Um ein "Rollen" von z. B. hochviskoser Druckfarbe - z. B. sog. "UV-Druckfarbe" - im Farbkasten 1 zu erleichtern, und so eine bessere Einfärbung der Fa rbdos i e rwa lze 4 zu ermöglichen, kann das Innere des Farbkastens 1, nämlich die Seitenwände 6; 7, die Stirnwände 15; 17 sowie die Fa rbdos i e re lemente, d. h. Rakelblätter 11; 12 mit einer Substanz 46 dauerhaft beschichtet sein, deren Obe r f läc henene rgi e einen niedrigen Wert z. B. zwischen 10 und 60 N/m aufweist. Solche Substanzen sind z. B. PTFE oder metallfreie amorphe Koh lens tof f s c h i cht en "a-C:H" (auch "DLC"-Sc h i cht en - ch amond-J ke-c^a rbon-Sch i chten genannt). Diese amorphen Koh lens tof f s c hi cht en bestehen aus einem hoch quervernetzten Koh lens tof fnetzwe rk, an das Wasserstoff angelagert ist. Durch Modifizierung der Netzwerkstruktur Fluor (F), Silizium (Si), Sauerstoff (0) und Stickstoff (N) und den prozentualen Anteilen kann die Oberflächenenergie der DLC-Schichten beeinflußt werden und damit das Benetzungsve rha l t en, die Härte und der Verschleiß wahlfrei beeinflußt werden.To "roll" z. B. highly viscous printing ink - z. B. so-called. "UV printing ink" - in the ink fountain 1, and thus to enable better coloring of the colors, ie the roller 4, the interior of the ink fountain 1, namely the side walls 6; 7, the end walls 15; 17 and the Fa rbdos ie re lemente, ie doctor blades 11; 12 be permanently coated with a substance 46, the upper surface of which has a low z. B. has between 10 and 60 N / m. Such substances are e.g. B. PTFE or metal-free amorphous carbon fschi cht en "aC: H" (also called "DLC" -Schicht en - ch amond-J ke-c ^ a rbon-Sch i chten). These amorphous carbon layers consist of a highly cross-linked carbon network to which hydrogen is attached. By modifying the network structure fluorine (F), silicon (Si), oxygen (0) and nitrogen (N) and the percentages, the surface energy of the DLC layers can be influenced and thus the wetting behavior, hardness and wear can be chosen to be influenced.
Außer den PTFE kann auch DLC + Fluor (F-DLC); DLC + Silizium (Si-DLC), DLC + Sauerstoff (0-DLC) und DLC + Stickstoff (N-DLC) und DLC + Bor (B-DLC) verwendet werden. Besonders geeignet sind F-DLC und Si-DLC.In addition to PTFE, DLC + fluorine (F-DLC); DLC + Silicon (Si-DLC), DLC + oxygen (0-DLC) and DLC + nitrogen (N-DLC) and DLC + boron (B-DLC) can be used. F-DLC and Si-DLC are particularly suitable.

Eine Beschichtung mit den Substanzen 46 erfolgt in einer Dicke, die zwischen 0,5 und 10 μm liegt. Diese Substanz 46 verhindert ein Anhaften von Druckfarbe 22 an beschichteten Teilen, z. B. im Inneren des Farbkastens 1. Insbesondere bei Verwendung von wasserlosen Druckfarben hoher Viskosität, z. B. größer 9000mPa*s oder bei sog. UV-Druckfarben kann eine Beschichtung mit den genannten Substanzen 46 mit Vorteil angewandt werden, weil sich dann leicht "rotierende D ruc k a rbenro L len" 24 bilden können, durch die eine bessere Einfärbung der Fa rbdos i e rwa Lze 4 erreicht wird. Die "Druckfarbenrolle" 24 bildet sich in der Nähe des Arbe i t s rake Lb lat tes 12 und der unmittelbar benachbarten Seitenwand 6 reibungsarm aus.A coating with the substances 46 takes place in a thickness that is between 0.5 and 10 μm. This substance 46 prevents ink 22 from adhering to coated parts, e.g. B. inside the ink fountain 1. Especially when using waterless printing inks of high viscosity, eg. B. greater than 9000mPa * s or with so-called UV printing inks, a coating with the substances 46 can be used with advantage, because then "rotating D ruc ka rbenro L len" 24 can form, through a better coloring of the company rbdos ie rwa Lze 4 is reached. The "ink roller" 24 forms near the work its rake Lb lat tes 12 and the immediately adjacent side wall 6 with little friction.
Wie schon gesagt, sind ein großer Teil oder alle unmittelbar mit der Druckfarbe 22 in Verbindung kommenden Teile des Farbkastens 1 mit der Substanz 46 beschichtet.As already mentioned, a large part or all of the parts of the ink fountain 1 which come into direct contact with the printing ink 22 are coated with the substance 46.
Es ist natürlich auch möglich, die Rakelblätter 11; 12 im gleichen Neigungswinkel an die Fa rbdos i e rwa Lze 4 anzustellen.It is of course also possible to use the doctor blades 11; 12 at the same angle of inclination to the fa rbdos i e rwa Lze 4.
Eine der Seitenwände 7; 6 ist vorzugsweise derart abgewinkelt, daß ein zwischen oberer Teilseitenwand 30 und unterer Teilseitenwand 35 gebildeter öffnungswinkel Gamma von ca. 90° sich zum Inneren des Farbkastens 1 hin öffnet. Dabei kann eine Breite d der oberen Teilseitenwand 30 gleich einer Breite e der unteren Teilseitenwand 35 sein. Jedoch kann auch d größer e sein oder umgekehrt. Mit 45 ist eine Längsachse des Farbkastens 1 und mit 48 ist eine Hochachse des Farbkastens 1 bezeichnet.One of the side walls 7; 6 is preferably angled in such a way that an opening angle gamma of approximately 90 ° formed between the upper partial side wall 30 and the lower partial side wall 35 opens towards the interior of the ink fountain 1. A width d of the upper partial side wall 30 can be equal to a width e of the lower partial side wall 35. However, d can also be greater than e or vice versa. 45 is a longitudinal axis of the ink fountain 1 and 48 is a vertical axis of the ink fountain 1.
Der Farbkasten 1 wird vorzugsweise - bezogen auf ein rechtwinkliges Koordinatensystem mit dem Ursprung auf der Rotationsachse 5 der Fa rbdos i e rwa Lze 4 - aus seiner im I. oder II. Quadranten oder im I. und II. Quadranten Liegenden Arbe i t s st e l Lung A - bezogen auf die Lage der Rakelblätter 11 auf der Fa rbdos i e rwa Lze 4 - in eine im I. und IV. Quadranten oder im II. und III. Quadranten liegende Ent Lee rste L lung verschwenkt (Lage der Rakelblätter 11, 12). Der Farbkasten 1 wird also aus einer Lage, in welcher die Querachse 40 des Farbkastens 1 horizontal oder annähernd horizontal verläuft, so verschwenkt, daß nach dem Verschwenken die Querachse 40 des Farbkastens 1 vertikal oder annähernd vertikal verläu t.The ink fountain 1 is preferably - based on a right-angled coordinate system with the origin on the axis of rotation 5 of the coloration 4 rwa - from its work lying in the 1st or 2nd quadrant or in the 1st and 2nd quadrant, its work its lung A. - based on the location of the Doctor blades 11 on the Fa rbdos ie rwa Lze 4 - in one in the 1st and 4th quadrants or in the 2nd and 3rd Quadrant lying Ent Lee rste Lung pivoted (position of the doctor blades 11, 12). The ink fountain 1 is thus pivoted from a position in which the transverse axis 40 of the ink fountain 1 runs horizontally or approximately horizontally so that after pivoting the transverse axis 40 of the ink fountain 1 runs vertically or approximately vertically.
Weiterhin ist es möglich, den Farbkasten 1 oben, d. h, an seiner oberen Kante 10 geschlossen auszubilden. Furthermore, it is possible to paint box 1 above, d. h to form closed on its upper edge 10.
