Definitions

  • the invention relates to a method and a device for supplying ink to an application roller for a rotary printing press according to the preamble of patent claims 1 and 2.

  • the printing ink is pressed through the perforations to the outer jacket by means of a hollow cylinder which can be freely rotated inside the inking roller.
  • a disadvantage of this rotating ink roller is that it has to be brought to a standstill in order to refill the printing ink, ie the printing process is interrupted.
  • a further disadvantage is that only an uneven wetting of the ink-permeable outer jacket occurs due to the support of the freely rotatable hollow cylinder inside the inking roller. At higher speeds of the inking roller, the freely rotatable hollow cylinder arranged inside the inking roller leads to unbalance phenomena, which results in poor print quality.
  • the invention has for its object to provide a method and an apparatus for feeding ink to an application roller for a rotary printing press, which emits ink from the inside of the roller through a jacket made of porous material to the outside of the printing unit, with one during operation and corresponding to the speed-dependent Production conditions of finely adjustable amount of ink that is continuously transferred from the surface of the inking roller to an inking roller.
  • the arrangement of the tubes on one another and the function of the inking roller according to the invention as a whole allow the printing ink to be metered — adapted to the respective production conditions. This is done by regulating the permeability in the radial direction by means of the position of the bores to one another.
  • the same color print is initially applied to all bores that run in the radial direction from the hollow axis, regardless of the position of the ink supply, since the ink take-off between the hollow axis and the first tube can be opened and closed depending on the frequency in order to build up the color print.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Zuführen von Farbe zu einer Auftragswalze für eine Rotationsdruckmaschine gemäß dem Oberbegriff des Patentanspruches 1 und 2.The invention relates to a method and a device for supplying ink to an application roller for a rotary printing press according to the preamble of patent claims 1 and 2.

Entsprechend der US 916 357 ist eine rotierende Farbwalze für Druckmaschinen bekannt, bei welcher die Druckfarbe aus dem Inneren der Farbwalze über zwei zueinander einstellbare hohlzylinderförmige sowie Perforationen aufweisende Körper zu einem farbdurchlässigen Außenmantel abgegeben wird. Mittels eines im Inneren der Farbwalze frei drehbaren Hohlzylinders wird die Druckfarbe durch die Perforationen zum Außenmantel gedrückt.According to US 916 357, a rotating ink roller for printing machines is known, in which the printing ink is dispensed from the interior of the ink roller via two mutually adjustable hollow cylindrical bodies with perforations to form a color-permeable outer jacket. The printing ink is pressed through the perforations to the outer jacket by means of a hollow cylinder which can be freely rotated inside the inking roller.

Nachteilig bei dieser rotierenden Farbwalze ist, daß diese zum Nachfüllen der Druckfarbe zum Stillstand gebracht werden muß, d. h. der Druckprozeß unterbrochen wird. Weiterhin ist von Nachteil, daß nur eine ungleichmäßige Benetzung des farbdurchlässigen Außenmantels durch die Auflage des frei drehbaren Hohlzylinders im Inneren der Farbwalze erfolgt. Bei höheren Drehzahlen der Farbwalze führt der im Inneren der Farbwalze angeordnete frei drehbare Hohlzylinder zu Unwuchterscheinungen, was eine schlechte Druckqualität zur Folge hat.A disadvantage of this rotating ink roller is that it has to be brought to a standstill in order to refill the printing ink, ie the printing process is interrupted. A further disadvantage is that only an uneven wetting of the ink-permeable outer jacket occurs due to the support of the freely rotatable hollow cylinder inside the inking roller. At higher speeds of the inking roller, the freely rotatable hollow cylinder arranged inside the inking roller leads to unbalance phenomena, which results in poor print quality.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Zuführen von Farbe zu einer Auftragswalze für eine Rotationsdruckmaschine, welche Farbe vom Walzeninneren durch einen Mantel aus porösem Material nach außen zum Druckwerk abgibt, zu schaffen mit einer während des Betriebszustandes und entsprechend den drehzahlabhängigen Produktionsbedingungen fein dosierbaren Farbmenge, die kontinuierlich von der Mantelfläche der Farbwalze einer Farbauftragwalze übergeben wird.The invention has for its object to provide a method and an apparatus for feeding ink to an application roller for a rotary printing press, which emits ink from the inside of the roller through a jacket made of porous material to the outside of the printing unit, with one during operation and corresponding to the speed-dependent Production conditions of finely adjustable amount of ink that is continuously transferred from the surface of the inking roller to an inking roller.

Erfindungsgemäß wird diese Aufgabe durch den kennzeichnenden Teil des Patentanspruches 1 und 2 gelöst.According to the invention, this object is achieved by the characterizing part of patent claims 1 and 2.

Bei der Benutzung der Erfindung treten insbesondere folgende Vorteile auf: Durch die Anordnung der Rohre aufeinander und durch die Funktion der erfindungsgemäßen Farbwalze insgesamt kann die Druckfarbe - den jeweiligen Produktionsbedingungen angepaßt - dosiert werden. Dies geschieht durch das Regulieren der Durchlaßfähigkeit in radialer Richtung mittels der Stellung der Bohrungen zueinander. Dabei steht an allen Bohrungen, die von der Hohlachse aus in radialer Richtung verlaufen, unabhängig von der Lage der Farbzuführung zunächst der gleiche Farbdruck an, da die Farbabnahme zwischen der Hohlachse und dem ersten Rohr zwecks Aufbau des Farbdruckes frequenzabhängig öffen- und schließbar ist.When using the invention, the following advantages occur in particular: the arrangement of the tubes on one another and the function of the inking roller according to the invention as a whole allow the printing ink to be metered — adapted to the respective production conditions. This is done by regulating the permeability in the radial direction by means of the position of the bores to one another. The same color print is initially applied to all bores that run in the radial direction from the hollow axis, regardless of the position of the ink supply, since the ink take-off between the hollow axis and the first tube can be opened and closed depending on the frequency in order to build up the color print.

Durch das Erzeugen einer konstanten Differenzdrehzahl zwischen dem zweiten Rohr und dem porösen Mantelrohr wird durch die Druck- und Sogwirkung des polygonen Profils der Oberfläche des zweiten Rohres auf das poröse dritte Mantelrohr eine pulsierende Sog- und Druckwirkung erzielt, die zu einem gleichmäßigen, homogenen Farbfilm auf der Oberfläche der Farbwalze führt. Dabei ist dieser Farbfilm in seiner Dicke dosierbar infolge der einstellbaren Durchlaßfähigkeit der Hohlachse zum ersten Rohr.By generating a constant differential speed between the second tube and the porous jacket tube, a pulsating suction and pressure effect is achieved by the pressure and suction effect of the polygonal profile of the surface of the second tube on the porous third jacket tube, resulting in a uniform, homogeneous color film the surface of the ink roller leads. The thickness of this color film can be adjusted due to the adjustable permeability of the hollow axis to the first tube.

Darüberhinaus besteht ein Gleichgewicht zwischen zugeführter und abgenommener Farbmenge bei einem jeweils gleichen Farbangebot.In addition, there is a balance between the amount of ink supplied and the amount removed with the same range of colors.

Die Vorrichtung muß nicht gereinigt werden. Sie kann nach der Benutzung ungereinigt aus der Maschine genommen, in eine Umhüllung, z. B. Folie, gepackt und bis zum nächsten Auftrag mit gleicher Farbe zwischengelagert werden. Dies ist vor allem von Vorteil bei Aufträgen mit kundenspezifischer Farbe.The device does not need to be cleaned. After use, it can be taken out of the machine uncleaned, in an envelope, e.g. As film, packed and temporarily stored with the same color until the next order. This is particularly advantageous for orders with customer-specific color.

Gemäß Fig. 1 ist die vereinfachte, schematische Darstellung der Anordnung einer erfindungsgemäßen Farbwalze 1 neben einer Auftragwalze 2 und einem Formzylinder 3 eines Druckwerkes gezeigt.1 shows the simplified, schematic representation of the arrangement of an inking roller 1 according to the invention in addition to an application roller 2 and a forme cylinder 3 of a printing unit.

Gemäß den Fig. 2 und 3 ist ersichtlich, daß die insgesamt mit 1 bezeichnete erfindungsgemäße Farbwalze eine Hohlachse 11 mit einem Farbspeicher 10 aufweist, die mittels Ringflanschen 12; 13 und Schrauben 14 an einem Gestell 16; 17 befestigt ist. Das Gestell 16; 17 ist an dem Maschinengestell 18; 19 befestigt. Die Hohlachse 11 ist über eine Bohrung 21 im Gestell 17 mit einer Farbzuleitung 22 verbunden, die zu einem nicht dargestellten, druckmittelbeaufschlagten Farbvorratsbehälter führt.According to FIGS. 2 and 3, it can be seen that the ink roller according to the invention, designated overall by 1, has a hollow axis 11 with an ink reservoir 10, which by means of ring flanges 12; 13 and screws 14 on a frame 16; 17 is attached. The frame 16; 17 is on the machine frame 18; 19 attached. The hollow shaft 11 is connected via a bore 21 in the frame 17 to an ink supply line 22, which leads to an ink reservoir, not shown, which is pressurized with pressure medium.

Die Hohlachse 11 weist am Umfang ringförmig angeordnete Bohrungen 24 auf, die - von der axial verlaufenden Mittellinie 23 der Farbwalze 1 aus gesehen - in radialer Richtung verlaufen und am Umfang miteinander fluchten, so daß diese so gebildeten "Ringe" entstehen, jeweils im Abstand a zueinander entfernt. Auf dieser Hohlachse 11 ist konzentrisch ein erstes Rohr 26 angeordnet, welches an einer Stirnseite eine Lasche 27 aufweist, an welcher gegen das Gestell 17 ein Arbeitszylinder 28 angelenkt ist. Der Arbeitszylinder 28 kann als pneumatischer Arbeitszylinder ausgeführt sein und mit einer bekannten, nicht dargestellten Regeleinrichtung in Verbindung stehen.The hollow axis 11 has holes 24 arranged in a ring on the circumference, which - seen from the axially running center line 23 of the inking roller 1 - run in the radial direction and on the circumference with one another align so that these "rings" are formed, each at a distance from each other. A first tube 26 is arranged concentrically on this hollow shaft 11, which has a tab 27 on one end face, on which a working cylinder 28 is articulated against the frame 17. The working cylinder 28 can be designed as a pneumatic working cylinder and can be connected to a known control device, not shown.

Ferner weist das erste Rohr 26 ebenfalls Bohrungen 29 auf, die - von der Mittellinie 23 der Farbwalze 1 aus gesehen - radial nach außen verlaufen, miteinander fluchten und ebenfalls in "Ringen" angeordnet und im Abstand a beabstandet sind. Die Anzahl der Bohrungen 29 je "Ring" des ersten Rohres 26 entspricht auch der Anzahl der Bohrungen 24 je "Ring" auf der Hohlachse 11.Furthermore, the first tube 26 likewise has bores 29 which, viewed from the center line 23 of the inking roller 1, run radially outward, are aligned with one another and are likewise arranged in “rings” and are spaced apart by a. The number of bores 29 per "ring" of the first tube 26 also corresponds to the number of bores 24 per "ring" on the hollow axis 11.

Fig. 2 zeigt die sogenannten "Ringe" mit der Anzahl der Bohrungen 29 je "Ring". Aufgrund der Tatsache, daß der Arbeitszylinder 28 mit der Lasche 27 des ersten Rohres 26 verbunden ist, ist dieses auf der Hohlachse 11 in Pfeilrichtung B abwechselnd hin- und her-, d. h. alternierend um einen Rotationswinkel mit einer einstellbaren Frequenz, bewegbar. Dieser Rotationswinkel ist so bemessen, daß dieser das maximale Maß c nach Fig. 2 betragen kann, gerade so viel, daß die radialen Bohrungen 24; 29 entweder miteinander vollständig durchlaßfähig oder vollständig gegeneinander verschlossen sind. Das bedeutet, daß der Kolben des Arbeitszylinders 28 in der einen Endlage die axiale Mittellinie 31 der Bohrungen 24 der Hohlachse 11 völlig in Übereinstimmung bringt mit der axial verlaufenden Mittellinie 32 der Bohrung 29, so daß diese zueinander hundertprozentig durchlaßfähig sind.Fig. 2 shows the so-called "rings" with the number of holes 29 per "ring". Due to the fact that the working cylinder 28 is connected to the tab 27 of the first tube 26, this can be moved back and forth alternately on the hollow axis 11 in the direction of arrow B, ie alternately by an angle of rotation with an adjustable frequency. This angle of rotation is dimensioned such that it can be the maximum dimension c according to FIG. 2, just enough that the radial bores 24; 29 are either completely permeable with each other or completely closed against each other. This means that the piston of the working cylinder 28 in one end position brings the axial center line 31 of the bores 24 of the hollow axis 11 completely in line with the axially extending center line 32 of the bore 29, so that they are 100% permeable to one another.

Die andere Endlage des Kolbens des Arbeitszylinders 28 bewirkt aufgrund der Bewegungsrichtung B des ersten Rohres 26 in die Gegenrichtung, daß die Bohrungen 24 der Hohlachse 11 um das Maß c versetzt sind zu den Bohrungen 29 des ersten Rohres 26, so daß diese Bohrungen 24; 29 zueinander hundertprozentig undurchlässig sind.The other end position of the piston of the working cylinder 28 causes due to the direction of movement B of the first tube 26 in the opposite direction that the bores 24 of the hollow axis 11 are offset by the dimension c to the bores 29 of the first tube 26, so that these bores 24; 29 are 100% impermeable to one another.

In Fig. 2 sind diese Bohrungen 24; 29 in einer Anordnung zueinander dargestellt, die etwa eine fünfzigprozentige Durchlaßfähigkeit zur Folge hat. Das bedeutet, daß das Maß c ebenfalls nur die Hälfte der Gesamthublänge des Kolbens des Arbeitszylinders 28 aufweist.2, these holes 24; 29 are shown in an arrangement with respect to one another which results in a fifty percent permeability. This means that the dimension c also has only half the total stroke length of the piston of the working cylinder 28.

Auf diesem ersten Rohr 26 ist koaxial ein zweites Rohr 33 angeordnet, welches an einer Stirnseite einen Flansch 34 aufweist, auf dem ein Zahnkranz 36 mittels Schrauben 37 befestigt ist. Der Zahnkranz 36 kämmt mit einem Zahnrad 38, das auf der Welle eines gestellfesten Motors 39 befestigt ist. Der Motor 39 steht mit einer nicht dargestellten, bekannten Regeleinrichtung in Verbindung.A second tube 33 is arranged coaxially on this first tube 26 and has a flange 34 on one end face, on which a ring gear 36 is fastened by means of screws 37. The ring gear 36 meshes with a gear 38 which is fixed on the shaft of a motor 39 fixed to the frame. The motor 39 is connected to a known control device, not shown.

Das zweite Rohr 33 weist eine Anzahl von Bohrungen 41 auf, die - von der axialen Mittellinie der Farbwalze 1 aus gesehen - radial nach außen verlaufen und miteinander fluchten, d. h. ebenfalls in "Ringen" nach Fig. 2 und im Abstand a nach Fig. 3 angeordnet sind. Die Anzahl der Bohrungen 41 im "Ring" oder Umfang des zweiten Rohres 33 kann so groß oder größer sein als die Anzahl der Bohrungen 24; 29 in der Hohlachse 11 bzw. im ersten Rohr 26. In Fig. 2 ist diese Anzahl der Bohrungen 41 ein Mehrfaches, z. B. dreimal so hoch wie die Anzahl der Bohrungen 24 oder 29.The second tube 33 has a number of bores 41 which, viewed from the axial center line of the inking roller 1, run radially outwards and are aligned with one another, i. H. are also arranged in "rings" according to FIG. 2 and at a distance a according to FIG. 3. The number of bores 41 in the "ring" or circumference of the second tube 33 can be as large or larger than the number of bores 24; 29 in the hollow axis 11 or in the first tube 26. In FIG. 2, this number of bores 41 is a multiple, eg. B. three times the number of holes 24 or 29.

Das dem ersten Rohr 26 abgewandte Ende der Bohrungen 41 des zweiten Rohres 33 endet gemäß Fig. 4 jeweils in einem Grund 42 oder im Tal einer Nut des zweiten Rohres 33. Mittig zwischen zwei Bohrungen 41 ist ein Plateau 43 gelegen, so daß das zweite Rohr 33 auf seinem Außenmantel ein regelmäßiges polygones Profil aufweist. Das zweite Rohr 33 ist über den Motor 39 sowie das Getriebe 38; 36 drehzahlgeregelt in Pfeilrichtung D antreibbar.The end of the bores 41 of the second tube 33 facing away from the first tube 26 ends in accordance with FIG. 4 in each case in a base 42 or in the valley of a groove of the second tube 33. A plateau 43 is located midway between two bores 41, so that the second tube 33 has a regular polygonal profile on its outer jacket. The second tube 33 is via the motor 39 and the gear 38; 36 driven by speed in the direction of arrow D.

Koaxial zur Mittellinie 23 ist auf dem zweiten Rohr 33 ein Mantelrohr 44 aus porösem Material angeordnet, das an seiner Stirnseite einen Zahnkranz 47 aufweist, der mit einem von der Maschine angetriebenen Zahnrad 48 kämmt. Der Zahnkranz 47 kann mittels Schrauben 46 an der Stirnseite des Mantelrohres 44 befestigt sein oder durch Kleben.A jacket tube 44 made of porous material is arranged on the second tube 33 coaxially to the center line 23 and has a toothed ring 47 on its end face which meshes with a gearwheel 48 driven by the machine. The ring gear 47 can be fastened to the end face of the casing tube 44 by means of screws 46 or by gluing.

Die Rohre 26; 33; 44 weisen jeweils an ihren beiden Stirnseiten je eine Aufnahme für ein Kugellager 49, 55, 57 auf, die die einzelnen Rohre 26; 33; 44 zueinander bzw. aufeinander abstützen und rotierbar gestalten. Dazu ist noch auf der Hohlachse 11 des ersten und zweiten Rohres 26; 33 ein Lagersitz vorhanden. Die Kugellager 49, 55, 57 werden durch Sicherungsringe 51 gegen Herausfallen gehalten.The tubes 26; 33; 44 each have at their two end faces a receptacle for a ball bearing 49, 55, 57, which the individual tubes 26; 33; 44 support each other or each other and make them rotatable. In addition, is on the hollow axis 11 of the first and second tube 26; 33 a bearing seat available. The ball bearings 49, 55, 57 are held against falling out by retaining rings 51.

Das Material für das erste Rohr 26, für das zweite Rohr 33 sowie für die Hohlachse 11 kann aus Stahl bestehen. Das erste Rohr 26 kann aber auch aus einem Material mit Notlaufeigenschaften, z. B. Messing, bestehen. Das Material für Mantelrohr 44 kann aus poröser Keramik oder porösem Kunststoff bestehen. Die in Fig. 1 gezeigte Auftragwalze 2 kann entfallen, wenn das Mantelrohr 44 aus einem porösen Kunststoff besteht, welcher kompressibel ist. Die Bohrungen der Hohlachse 11 bzw. des ersten Rohres 26 weisen gleiche Durchmesser auf.The material for the first tube 26, for the second tube 33 and for the hollow axis 11 can be made of steel. The first tube 26 can also be made of a material with emergency running properties, e.g. B. brass exist. The material for casing tube 44 can be made of porous ceramic or porous plastic. The applicator roller 2 shown in FIG. 1 can be omitted if the casing tube 44 consists of a porous plastic which is compressible. The bores of the hollow axis 11 and the first tube 26 have the same diameter.

Die Funktionsweise der erfindungsgemäßen Farbwalze 1 wird nachfolgend beschrieben: Die Farbzufuhr erfolgt durch die Farbzuleitung 22 in Pfeilrichtung F in den Farbspeicher 10 der Hohlachse 11 von dem nicht dargestellten Farbvorratsbehälter. Die Farbe dringt in die Bohrungen 24 der Hohlachse 11 ein und steigt in diesen hoch, von der Mittellinie 23 ausgehend, in radialer Richtung auf das erste Rohr 26 zu.The mode of operation of the ink roller 1 according to the invention is described below: The ink supply takes place through the ink feed line 22 in the direction of arrow F into the ink reservoir 10 of the hollow axis 11 from the ink reservoir, not shown. The paint penetrates into the bores 24 of the hollow axis 11 and rises in the radial direction toward the first tube 26, starting from the center line 23.

Je nach voreingestellter Hublänge des Kolbens des Arbeitszylinders 28, der an einer Stirnseite des ersten Rohres 26 angreift bzw. des dadurch bewerkstelligten Rotationswinkels des ersten Rohres 26, wird die Durchlaßfähigkeit der Bohrungen 24 zu den Bohrungen 29 bemessen. Die Durchlaßfähigkeit beträgt entsprechend der Darstellung in Fig. 2 etwa fünfzig Prozent und ist einstellbar entsprechend den Produktionsbedingungen. Diese Durchlaßfähigkeit wird von einer nicht dargestellten, bekannten Steuer- und Regeleinrichtung vorgenommen, die beispielsweise mit dem Rechner im Maschinenleitstand der Druckmaschine zusammenarbeiten kann.Depending on the preset stroke length of the piston of the Working cylinder 28, which engages on an end face of the first tube 26 or the rotation angle of the first tube 26 thereby achieved, the permeability of the bores 24 to the bores 29 is dimensioned. The permeability is approximately fifty percent as shown in Fig. 2 and is adjustable according to the production conditions. This permeability is carried out by a known control and regulating device, not shown, which can work, for example, with the computer in the machine control center of the printing press.

Durch die Vor- und Rückbewegung des ersten Rohres 26 in Pfeilrichtung B nach Fig. 2 wird beispielsweise die Durchlaßfähigkeit zu maximal fünfzig Prozent in der einen Endstellung des Arbeitszylinders 28 und zu null Prozent in der anderen Endstellung des Arbeitszylinders 28 geregelt.The forward and backward movement of the first tube 26 in the direction of arrow B according to FIG. 2, for example, regulates the permeability to a maximum of fifty percent in one end position of the working cylinder 28 and to zero percent in the other end position of the working cylinder 28.

Während der Zeitdauer der Durchlaßfähigkeit zu null Prozent kann sich im Inneren der Hohlachse 11 ein neuer, gleichmäßiger Farbdruck aufbauen. Somit werden auch die auf der gegenüberliegenden Seite der Farbzuleitung 22 in der Hohlachse 11 liegenden Bohrungen 24, d. h. die in der Nähe des Ringflansches 12 liegenden Bohrungen 24, gleichmäßig mit Druckfarbe beschickt.During the period of permeability to zero percent, a new, uniform color print can build up inside the hollow axis 11. Thus, the holes 24 lying on the opposite side of the ink supply line 22 in the hollow axis 11, i. H. the holes 24 located near the ring flange 12, evenly loaded with printing ink.

Die Hubfrequenz des Kolbens des Arbeitszylinders 28 ist über die bereits oben erwähnte nicht dargestellte, bekannte Steuer- und Regeleinrichtung einstellbar. Die Hubfrequenz kann z. B. drei Hertz betragen. Es besteht ein umgekehrtes proportionales Verhältnis zwischen Hublänge und Frequenz, d. h. je größer die Hublänge, desto geringer die Frequenz und umgekehrt, für den gleichen Farbdurchsatz.The stroke frequency of the piston of the working cylinder 28 is adjustable via the known control and regulating device not mentioned above. The stroke frequency can e.g. B. be three Hertz. There is an inverse proportional relationship between stroke length and frequency, ie the longer the stroke length, the lower the frequency and vice versa, for the same color throughput.

Durch die Rotation des zweiten Rohres 33 in Pfeilrichtung D werden zeitweilig die Bohrungen 41 mit den Bohrungen 29 des ersten Rohres 26 in Übereinstimmung gebracht. Eine größere Anzahl von Bohrungen 41 je "Ring" in dem zweiten Rohr 33 gegenüber einer kleineren Anzahl von Bohrungen 29 je "Ring" in dem ersten Rohr 26 geben eine Gewähr für eine Feinverteilung der Druckfarbe.Due to the rotation of the second tube 33 in the direction of arrow D, the bores 41 are brought into alignment with the bores 29 of the first tube 26. A larger number of bores 41 per "ring" in the second tube 33 compared to a smaller number of bores 29 per "ring" in the first tube 26 guarantee a fine distribution of the printing ink.

Durch die gegenläufige Rotation des Mantelrohres 44 in Pfeilrichtung E zum zweiten Rohr 33 in Richtung D entsteht zwischen dem zweiten Rohr 33 und dem Mantelrohr 44 eine Relativdrehzahl oder ein Schlupf.The opposite rotation of the casing tube 44 in the direction of arrow E to the second pipe 33 in direction D creates a relative speed or slip between the second pipe 33 and the casing pipe 44.

Gemäß Fig. 4 sind Kammern 50 gezeigt, die zwischen dem Grund 42 mit dem Ende der Bohrung 41 und oberhalb mit der Innenseite 54 dem aus porösem Material bestehenden Mantelrohr 44 gebildet und beidseitig durch jeweils ein Plateau 43 begrenzt werden. In der linken Kammerhälfte 52 tritt infolge der Differenzdrehzahl des Mantelrohres 44 bzw. des zweiten Rohres 33 eine Sogwirkung oder ein Unterdruck ein und in der rechten Kammerhälfte 53 ein Überdruck. Dadurch kommt an der Oberfläche 56 bzw. am Außenmantel des Mantelrohres 44 ein Pulsieren zustande, was eine regelmäßige Farbbenetzung der Oberfläche 56 des Mantelrohres 44 zur Folge hat. Somit kann - an die Produktionsbedingungen angepaßt - eine dosierbare, kontinuierliche und über die gesamte Oberfläche feinst verteilte Farbschicht erzielt werden, die gemäß Fig. 1 über die Auftragwalze 2 weiter in das Druckwerk gegeben wird.4, chambers 50 are shown which are formed between the base 42 with the end of the bore 41 and above with the inside 54 the casing tube 44 made of porous material and are delimited on both sides by a plateau 43. A suction effect or occurs in the left half of the chamber 52 due to the differential speed of the casing tube 44 or the second tube 33 A vacuum and in the right half of the chamber 53 an overpressure. As a result, a pulsation occurs on the surface 56 or on the outer jacket of the jacket tube 44, which results in regular wetting of the surface 56 of the jacket tube 44. Thus, adapted to the production conditions, a meterable, continuous and finely distributed ink layer can be achieved, which is passed on to the printing unit 2 according to FIG. 1 via the application roller 2.

Die Differenzdrehzahl zwischen dem zweiten Rohr 33 und dem Mantelrohr 44 wird annähernd konstant gehalten. So kann diese Differenzdrehzahl 2.500 bis 3.500 Umdrehungen pro Stunde betragen. Das heißt: Bei einer Maschinendrehzahl von 3.000 Umdrehungen pro Stunde durch das Mantelrohr 44 in Pfeilrichtung E nach Fig. 2 werden 500 Umdrehungen pro Stunde in Gegenpfeilrichtung D durch das rotierende zweite Rohr 33 erbracht, so daß insgesamt eine Differenzdrehzahl von 3.500 Umdrehungen pro Stunde entsteht. Infolge der höheren Drehzahl des Mantelrohres 44 gegenüber der Drehzahl des zweiten Rohres 33 weist das Mantelrohr 44 eine positive Differenzdrehzahl auf.The differential speed between the second tube 33 and the jacket tube 44 is kept approximately constant. This differential speed can be 2,500 to 3,500 revolutions per hour. That means: At a machine speed of 3,000 revolutions per hour through the casing tube 44 in the direction of arrow E according to FIG. 2, 500 revolutions per hour in the opposite arrow direction D through the rotating second tube 33, so that a total differential speed of 3,500 revolutions per hour arises. As a result of the higher speed of the casing tube 44 compared to the speed of the second pipe 33, the casing tube 44 has a positive differential speed.

Für den Fall, daß die Maschinendrehzahl steigt und somit auch die Anzahl der Umdrehungen der Farbwalze 1, d. h. insbesondere des Mantelrohres 44, auf beispielsweise 6.000 Umdrehungen pro Stunde, muß bei einer Differenzdrehzahl von 2.500 Umdrehungen pro Stunde zwischen dem Mantelrohr 44 und dem zweiten Rohr 33, das zweite Rohr 33 eine Drehzahl von 3.500 Umdrehungen pro Stunde erbringen, die jedoch gleichsinnig in Pfeilrichtung E gemäß Fig. 2 erfolgen muß. Das heißt, daß die Drehrichtung des zweiten Rohres 33 von D nach E umgekehrt wurde.In the event that the machine speed increases and thus also the number of revolutions of the inking roller 1, ie in particular the jacket tube 44, for example to 6,000 revolutions per hour, must be at a differential speed of 2,500 revolutions per hour between the jacket tube 44 and the second tube 33, the second tube 33 bring a speed of 3,500 revolutions per hour, but this must be done in the same direction in the direction of arrow E according to FIG. 2. This means that the direction of rotation of the second tube 33 was reversed from D to E.

Ergänzend zu dem Vorgenannten wird noch folgendes ausgeführt:
Die zwischen den einzelnen Rohren 26, 33, 44 bzw. auf der Hohlachse 11 befindlichen Kugellager 49, 55, 57 weisen beidseitig Dichtscheiben auf. Die Mantelflächen der koaxial aufeinander angeordneten Rohre 11, 26, 33, 44 gleiten aufeinander in einer Passung, so daß die Druckfarbe nur durch die in radialer Richtung angeordneten Bohrungen 24, 29, 41 zum Mantelrohr 44 gelangen kann. Die aus der linken Kammerhälfte 52 und der rechten Kammerhälfte 53 gebildeten Kammern 50 weisen etwa linsenförmigen Querschnitt auf, so daß infolge der Differenzdrehzahl beider Rohre 44, 33 in der linken Kammerhälfte 52 entsprechend der Drehrichtung E des Mantelrohres 44 im Uhrzeigersinn ein Sog und in der rechten Kammerhälfte 53 ein Überdruck durch die in der Kammerhälfte 53 anliegende Druckfarbe entsteht, so daß die in der rechten Kammerhälfte 53 befindliche Druckfarbe von der Innenseite 54 des Mantelrohres 44 aufgenommen wird.In addition to the above, the following is also carried out:
The ball bearings 49, 55, 57 located between the individual tubes 26, 33, 44 or on the hollow axis 11 have sealing washers on both sides. The lateral surfaces of the coaxially arranged tubes 11, 26, 33, 44 slide on one another in a fit, so that the printing ink can only reach the tubular casing 44 through the bores 24, 29, 41 arranged in the radial direction. The chambers 50 formed from the left-hand chamber half 52 and the right-hand chamber half 53 have an approximately lenticular cross-section, so that due to the differential speed of the two tubes 44, 33 in the left-hand chamber half 52 in accordance with the direction of rotation E of the casing tube 44, a suction and in the right-hand direction Chamber half 53 creates an overpressure due to the printing ink in the chamber half 53, so that the printing ink located in the right chamber half 53 is absorbed by the inside 54 of the casing tube 44.

Im Grund 42 der Kammer 50 erfolgt die Farbzuführung durch die Bohrung 41. Am äußeren Umfang des zweiten Rohres 33 befindet sich eine Vielzahl von Kammern 50, die jeweils durch direkt an der Innenseite des Mantelrohres 44 und an ihre Krümmung angepaßte anliegende Plateaus 43 getrennt sind.In the base 42 of the chamber 50, the ink is supplied through the bore 41. On the outer circumference of the second tube 33 there is a multiplicity of chambers 50, each of which is separated by adjacent plateaus 43 which are adapted directly to the inside of the jacket tube 44 and to their curvature.

Die in ihrem Querschnitt etwa linsenförmig ausgebildeten genannten Kammern 50 verlaufen als Nut in axialer Richtung in der Mantelfläche des zweiten Rohres 33 und enden jeweils an den inneren Laufringen der mit Dichtscheiben versehenen Kugellager 55, 57, die zwischen dem zweiten Rohr 33 und dem Mantelrohr 44 angeordnet sind.The chambers 50, which are approximately lenticular in their cross section, run as a groove in the axial direction in the outer surface of the second tube 33 and each end on the inner races of the ball bearings 55, 57 provided with sealing disks, which are arranged between the second tube 33 and the outer tube 44 are.

Es ist auch möglich, die Kammern 50 zwischen ihren stirnseitigen Begrenzungen durch die Kugellager 49 nicht in axialer Richtung verlaufen zu lassen, sondern mit einem geringen Drall zu versehen. Durch die abwechselnde Anordnung von Kammern 52, 53 und Plateaus am Umfang des zweiten Rohres 33 ergibt sich ein polygoner Querschnitt derselben. Unter einer polygonen Oberfläche des zweiten Rohres 33, wie früher in der Beschreibung erwähnt, ist ein polygoner Querschnitt am Außenumfang des zweiten Rohres 33 zu verstehen.It is also possible not to let the chambers 50 run in the axial direction between their end boundaries by the ball bearings 49, but to provide them with a slight twist. The alternating arrangement of chambers 52, 53 and plateaus on the circumference of the second tube 33 results in a polygonal cross section thereof. A polygonal surface of the second tube 33, as mentioned earlier in the description, is to be understood as a polygonal cross section on the outer circumference of the second tube 33.
