Die auf Seiten 2 bis 7 beschriebenen und in Abbildung 1 dargestellten Ausführungsbeispiele fallen nicht unter den Schutzbereich der Ansprüche.The exemplary embodiments described on pages 2 to 7 and shown in Figure 1 do not fall within the scope of the claims.

Ein oben offener (druckloser) Farbkasten 1 hat eine linke und eine rechte Seitenwand 2; 3 sowie zwei der Peripherie 21 einer angetriebenen Walze 4 angepaßte abdichtende Stirnwände 6; 7. Der Farbkasten 1 erstreckt sich über die gesamte Länge der Walze 4, die z. B. als Rasterwalze oder als Tiefdruckzylinder ausgebildet sein kann. Unten an den Seitenwänden 2; 3 sind eine Arbeitsrakel 8 sowie eine Schließrakel 9 auswechselbar angebracht.An open (pressureless) ink fountain 1 has one left and right side wall 2; 3 and two of the Periphery 21 of a driven roller 4 adapted sealing end walls 6; 7. The ink fountain 1 extends over the entire length of the roller 4, the z. B. as Anilox roller or as a gravure cylinder can. Below on the side walls 2; 3 are one Working squeegee 8 and a closing squeegee 9 interchangeable appropriate.

Statt Rakeln 8; 9 könnten auch über die Länge der Walze 4 einzeln nebeneinander angeordnete Farbdosiermesser eingesetzt werden.Instead of squeegees 8; 9 could also be along the length of the roller 4 color metering knives arranged individually next to each other be used.

Im Farbkasten 1 befindet sich vorzugsweise hochviskose Druckfarbe 11 (größer 60 Poise), welche während des Maschinenlaufes entsprechend der Drehrichtung der Walze 4, z. B. im Gegenuhrzeigersinn A eine an der linken Innenseite 17 der Seitenwand 2 sowie an der lichten Breite b sowie Länge der Rakel 8 anliegende Farbrolle 12 ausbildet. Die Rakelkante der Rakel 8 rakelt von der Oberfläche 21 der Walze 4 Druckfarbe ab.The ink fountain 1 is preferably highly viscous Ink 11 (greater than 60 poise), which during the Machine run according to the direction of rotation of the roller 4, e.g. B. counterclockwise A on the left Inside 17 of the side wall 2 and on the clear Width b and length of the doctor blade 8 adjacent ink roller 12 trains. The squeegee edge of the squeegee 8 squeegees from the Surface 21 of the roller 4 printing ink.

Die rotierende Farbrolle 12 hat an einer bestimmten Stelle ihrer Länge eine Solldicke d1, die proportional der aus dem Farbkasten 1 verbrauchten und wieder eingefüllten Druckfarbe ist. Mittels einer direkt oder indirekt auf die Farbrolle 12 gerichteten seitengestellfesten oder farbwannenfesten Einrichtung 28 wird fortlaufend oder in einstellbaren Intervallen gemessen und das Ergebnis der Messung ausgewertet.The rotating paint roller 12 has a particular one Place their length a target thickness d1, which is proportional the used up from the ink fountain 1 and again filled ink. By means of a direct or directed indirectly at the paint roller 12 device fixed to the side frame or to the paint tray 28 will be continuous or at adjustable intervals measured and the result of the measurement evaluated.

Ein Abstandsmessen erfolgt wahlweise mittels optischer oder akustischer Mittel, z. B. Laserstrahlen oder Ultraschall, welche von der Einrichtung 28 ausgesandt werden und direkt und berührungslos auf die Oberfläche 21 der Farbrolle 12 auftreffen. Auf Grund der bekannten Entfernung zwischen der Oberfläche der Walze 4 und der Einrichtung 28 wird dann die Dicke d1 der Farbrolle 12 ermittelt. A distance measurement is optionally carried out using optical or acoustic means, e.g. B. laser beams or Ultrasound emitted by the device 28 and directly and without contact on the surface 21 of the paint roller 12 hit. Because of the known Distance between the surface of the roller 4 and the Device 28 then becomes the thickness d1 of the paint roller 12 determined.

Infolge der Abgabe von Druckfarbe 11 während des Maschinenlaufes bildet sich eine Farbrolle 32 mit einer verringerten Dicke d2 aus - gestrichelt Darstellung -. Daraufhin gibt die Einrichtung 28 ein Signal ab, was eine nichtdargestellte Farbpumpe in Gang setzt, die dem Farbkasten 1 über den Farbzulauf 27 neue Druckfarbe zuführt.As a result of the delivery of ink 11 during the A roller 32 forms with a machine run reduced thickness d2 from - dashed representation -. The device 28 then emits a signal as to what starts a paint pump, not shown, that the Ink box 1 via the ink inlet 27 new printing ink feeds.

Bei einer großen negativen Abweichung d3 oder großen positiven Abweichung d4 der Dicke der Farbrolle 33; 34 - gestrichelte Darstellung - wird ein optisches und/oder akustisches Warnsignal ausgegeben, welches das Bedienpersonal auf einen Fehler im Farbwerk aufmerksam macht.With a large negative deviation d3 or large positive deviation d4 of the thickness of the paint roller 33; 34 - dashed line - becomes an optical one and / or acoustic warning signal, which the Operating personnel are alerted to an error in the inking unit makes.

Die Einrichtung 28 ist mittels einer elektrischen oder optischen Leitung 29 mit dem Maschinenleitstand verbunden. Mittels eines Vorwahlschalters 30; 31 sind der zu messende Zeitintervall sowie der fixe Abstandswert einstellbar.The device 28 is by means of an electrical or optical line 29 with the machine control center connected. By means of a pre-selection switch 30; 31 are the time interval to be measured and the fixed one Distance value adjustable.

Die Einrichtung 28 kann, wie in der Zeichnung gestrichelt dargestellt, über die Oberkante 38 des Farbkastens 1 hinausragend angeordnet sein. Es ist auch möglich, Messungen mit auf kapazitiver Grundlage arbeitender Einrichtung vorzusehen.The device 28 can, as in the drawing shown in dashed lines, over the top edge 38 of the Color box 1 can be arranged protruding. It is also possible to measure on a capacitive basis to provide working facility.

Weiterhin kann die Einrichtung 28 aber auch längs des Farbkastens 1 auf einer walzenparallel 1 befestigten Führungsschiene manuell oder motorisch verfahrbar angeordnet sein.Furthermore, the device 28 can also along the Ink box 1 attached to a roller 1 parallel Guide rail can be moved manually or by motor be arranged.

Nach einem anderen Ausführungsbeispiel ist an einem an der Innenseite 17 der linken Seitenwand 2 befestigten Lager 18 ein Farbrollen-Fühlhebel 23 angelenkt, dessen Unterseite 36 tangential an der Peripherie 21 der Farbrolle 12 anliegt. Somit wird eine Entfernung zwischen der Oberseite 37 des Farbrollen-Fühlhebels 23 und der Einrichtung 28 indirekt und kontaktbehaftet gemessen, so daß sich unter Berücksichtigung der Materialdicke des Farbrollen-Fühlhebels 23 die verschiedenen Dicken d1 bis d4 der Farbrollen 12; 32; 33; 34 ermitteln lassen.According to another embodiment, one is on attached to the inside 17 of the left side wall 2 Bearing 18 hinged a paint roller feeler lever 23, the Bottom 36 tangential to the periphery 21 of the Ink roller 12 is applied. So there is a distance between the top 37 of the paint roller feeler lever 23 and the device 28 indirectly and in contact measured so that taking into account the Material thickness of the ink roller feeler 23 die different thicknesses d1 to d4 of the paint rollers 12; 32; 33; 34 have it determined.

Nach einem dritten Ausführungsbeispiel kann der Farbrollen-Fühlhebel 23 als zweiarmiger Fühlhebel 16 ausgebildet sein, dessen zweiter Arm 22 in Richtung öffnung des Farbkastens 1 weist und in einem Winkel Alpha, z. B. von 130° bis 140° mit dem ersten Arm 23 im Lager 18 zusammenläuft. Eine auf der Oberkante 38 der rechten Seitenwand 3 angeordnete Einrichtung 39 - gestrichelt dargestellt - mißt eine horizontale Entfernung zwischen der Einrichtung 39 und der Vorderseite 41 und des zweiten Armes 22 wiederum in indirekter und kontaktbehafteter Weise, während die Unterseite 36 des ersten Armes 23 an der Peripherie 21 der Farbrolle 12 anliegt. In Abhängigkeit von der Dicke d1 bis d4 der Farbrolle 12; 32; 33; 34 ändert sich die Lage des zweiarmigen Fühlhebels 16, so daß die Einrichtung 39; 16 die Dicke der Farbrolle feststellt. Die Einrichtung 39 kann ebenso wie die Einrichtung 28 ausgebildet sein.According to a third embodiment, the Paint roller feeler lever 23 as a two-arm feeler lever 16 be formed, the second arm 22 in the direction opening of the ink fountain 1 points and at an angle Alpha, e.g. B. from 130 ° to 140 ° with the first arm 23 in Camp 18 converges. One on the top edge 38 of the right side wall 3 arranged device 39 - shown in dashed lines - measures a horizontal Distance between device 39 and the Front 41 and the second arm 22 in turn in an indirect and contact way, while the Bottom side 36 of the first arm 23 on the periphery 21 the ink roller 12 rests. Depending on the thickness d1 to d4 of the paint roller 12; 32; 33; 34 changes the position of the two-armed Feeler lever 16 so that the device 39; 16 the thickness the paint roller detects. The device 39 can also be designed as the device 28.

Nach einem vierten Ausführungsbeispiel weist der zweiarmige Fühlhebel 16 am Ende seines zweiten Armes 22 eine Fahne 24 auf, welche z. B. mit einer induktiven Einrichtung 13 in berührungslosem Kontakt steht. Die Fahne 24 kann aus Eisenblech bestehen. Die Unterseite 36 des ersten Armes 23 des zweiarmigen Fühlhebels 16 liegt tangential an der Farbrolle 12 mit der Dicke d1 an, so daß sich der Fühlhebel 16 in Lage I befindet. Während des Maschinenlaufes verringert sich die Farbmenge, so daß eine Farbwalze 32 eine verringerte Dicke d2 aufweist. Dabei befindet sich der zweiarmige Fühlhebel 16 in Lage II - gestrichelt dargestellt -. Von der Einrichtung 13 wird ein Signal zur Steuerung des Farbzulaufes 27 ausgegeben, so daß die Farbrolle wieder die Solldicke d1 erreicht.
Die Einrichtung 13 ist seitengestell- oder farbkastenfest angeordnet und ist über eine elektrische Leitung 26 mit dem Maschinenleitstand verbunden.
According to a fourth embodiment, the two-armed feeler lever 16 at the end of its second arm 22 has a flag 24 which, for. B. is in contactless contact with an inductive device 13. The flag 24 can consist of sheet iron. The underside 36 of the first arm 23 of the two-armed feeler lever 16 lies tangentially on the paint roller 12 with the thickness d1, so that the feeler lever 16 is in position I. The amount of ink decreases while the machine is running, so that an inking roller 32 has a reduced thickness d2. The two-armed feeler lever 16 is in position II - shown in broken lines -. A signal for controlling the ink feed 27 is output by the device 13 so that the ink roller again reaches the target thickness d1.
The device 13 is fixed to the side frame or ink fountain and is connected to the machine control station via an electrical line 26.

Die Vorrichtung ist natürlich auch so einstellbar, daß bereits bei einer geringen Verringerung der Solldicke d1 ein sofortiges kurzes Einschalten des Farbzulaufes 27 erfolgen kann. Vorzugsweise wird die Dicke der Farbwalze fortlaufend oder in vorwählbaren Zeitabständen abgetastet.The device is of course also adjustable so that even with a slight reduction in the target thickness d1 an immediate brief switch-on of the ink inlet 27 can be done. Preferably the thickness of the ink roller continuously or at pre-selectable intervals scanned.

Vorteilhafterweise wird über einen vorgegebenen Zeitraum z. B. von fünf Minuten mittels einer bekannten Auswerteschaltung ermittelt, wieviel Intervalle d1; d2; d1 bei einem ordnungsgemäßen Druckbetrieb - unter Berücksichtigung des Farbflächenanteils des Bedruckstoffes sowie der Maschinendrehzahl - auftreten. Z. B. entstehen im vorgegebenen Zeitraum von fünf Minuten fünf Intervalle.Advantageously, over a predetermined period of time e.g. B. of five minutes using a known Evaluation circuit determines how many intervals d1; d2; d1 with proper printing operation - under Consideration of the color area share of the Substrate and the machine speed - occur. For example, there are five in the given period Minutes five intervals.

Sollte eine Unterschreitung der vorgegebenen Anzahl von Intervallen erfolgen, so ist dies ein Anzeichen für ein fehlerhaftes Ausbilden der Farbwalze und somit ein Anzeichen für eine fehlerhafte Abgabe der Farbmenge. In diesem Falle wird ein zusätzliches Alarmsignal ausgegeben.Should the number of Intervals occur, this is a sign of a incorrect formation of the ink roller and thus a Signs of incorrect delivery of the amount of paint. In in this case an additional alarm signal spent.

Das Prinzip der Verfahren besteht darin, daß der Farbkasten 2 so mit Druckfarbe, z. B. hochviskoser, befüllt ist, daß während des Betriebszustandes ein Teil des unteren Farbkastens 2 frei ist von Druckfarbe, während sich im anderen unteren Teil des Farbkastens 2 eine Farbrolle 12 ausbildet. Dieser Zustand wird nach weiteren Ausführungsbeispielen festgestellt und ausgewertet.The principle of the procedure is that the Ink box 2 so with printing ink, e.g. B. highly viscous, is filled that part during the operating state of the lower ink fountain 2 is free of printing ink, while in the other lower part of the color box 2 forms a paint roller 12. This state is after other embodiments found and evaluated.

Nach einem fünften Ausführungsbeispiel (Fig. 2) ist zur fortlaufenden oder intervallmäßigen berührungslosen Messung der Dicke d1 der Farbrolle 12 über dem Farbkasten 1 eine um einen Winkel Beta von ca. 20° in Umfangsrichtung der Walze 4 verschwenkbare Meßeinrichtung 39, z. B. ein Ultraschallsensor oder Laufzeitsensor angeordnet. Diese Meßeinrichtung 39 mißt die Entfernung zu den Ebenen C und E.

Der second leg 47 runs vertically and parallel to Side wall 2. Level C is approximately in one Distance above the surface of the roller 4, which the Diameter d1 corresponds to a paint roller 12 (FIG. 7).

Es ist weiterhin möglich, den Dehnungsmeßstreifen 44 auch auf dem zweiten Schenkel 47 des Winkelhebels 43 anzuordnen.It is also possible to use the strain gauge 44 also on the second leg 47 of the angle lever 43 to arrange.

Nach einem elften Ausführungsbeispiel (Fig. 8) ist die Seitenwand 2 und/oder 3 zum Inneren des Farbkastens 1 hin zurückgenommen. Die dadurch entstandene Vertiefung wird von einem Biegeblech 48 abgedeckt. Es ist am oberen Teil der Seitenwand 2 bzw. 3 befestigt und bildet mit seinem unteren Ende und der Innenfläche der Rakeln 8 und 9 einen ganz kleinen Spalt oder liegt auf ihnen auf. An der Innenseite des Biegebleches 48 ist, in die Vertiefung hineinragend, zumindest ein Dehnungsmeßstreifen 49 appliziert. Durch Berührung der rotierenden Farbrolle 12 mit dem Biegeblech 48 wird ein Biegemoment erzeugt, das der Dehnungsmeßstreifen 49 erfaßt und ein entsprechendes Signal abgibt, das ausgewertet wird. Auch können vom Dehnungsmeßstreifen Schwingungen erfaßt werden, die ausgewertet werden und als Indiz für eine Rotationsbewegung der Farbrolle 12 ausgewertet werden.According to an eleventh embodiment (Fig. 8) Side wall 2 and / or 3 to the interior of the ink fountain 1 withdrawn. The resulting deepening is covered by a bending plate 48. It is at the top Part of the side wall 2 and 3 attached and forms with its lower end and the inner surface of the doctor blades 8 and 9 a very small gap or lies on them. On the inside of the bending plate 48, in the Protruding, at least one Strain gauge 49 applied. By touching the rotating paint roller 12 with the bending plate 48 becomes a Bending moment generated that the strain gauge 49th detected and emits a corresponding signal that is evaluated. Also from the strain gauge Vibrations are detected, which are evaluated and as an indication of a rotational movement of the paint roller 12 be evaluated.

Der Abstand h kann bis zu einigen Millimetern betragen.The distance h can be up to a few millimeters.

Es ist jedoch auch möglich, zwischen dem Träger 48 und der Seitenwand 2 elastisches Material, z. B. Silikonkautschuk anzuordnen.However, it is also possible to between the carrier 48 and the side wall 2 elastic material, e.g. B. Arrange silicone rubber.

Nach einer nicht dargestellten Ausführungsvariante weist mindestens eine der Seitenwände eine Druckmeßdose auf. Bei Berührung der Farbrolle 12 mit der Druckmeßdose wird ein Signal ausgegeben. According to a variant not shown at least one of the side walls on a pressure cell. When the paint roller 12 touches the load cell issued a signal.

Beim Ausführungsbeispiel nach Fig. 9 arbeitet die Einrichtung wie beim Gegenstand der Fig. 8. Anstatt an seinem unteren Ende freien Biegebleches 48 wird nun ein Biegeblech 51 verwendet, das oben und unten an der Seitenwand 2 und/oder 3 befestigt ist und so eine Vertiefung oder Öffnung 52 in ihnen - dicht gegen Druckfarbeneintritt - abdeckt.In the embodiment of FIG. 9, the Setup as in the subject of Fig. 8. Instead of its lower end of free bending plate 48 is now one Bending plate 51 used, the top and bottom of the Side wall 2 and / or 3 is attached and so one Indentation or opening 52 in them - tight against Ink entry - covers.

Das "Biegeblech" kann, wie aus der Fig. 9 zu sehen, auch durch Materialabtrag von der Seitenwand 2 und/oder 3 von außen her erfolgen. Hierdurch kann die Seitenwand 2; 3 durch die rotierende Farbrolle 2 erzeugten hydrodynamischen Kräfte auf Biegung beansprucht werden. Diese erzeugten Biegespannungen können mittels Dehnungsmeßstreifen 49 erfaßt und ausgewertet werden. Sie sind ein Maß zur Bewertung, ob sich die Farbrolle 2 dreht. Dieses kann auch über die Dehnungsmeßstreifen 49 auf andere Art festgestellt werden. Es können nämlich auch aus den Signalen der Dehnungsmeßstreifen die Schwingungen elektronisch ausgewertet werden, durch die die rotierende Farbrolle 2 das Biegeblech 51 anregt. The "bending plate" can, as can be seen from FIG. 9, also by removing material from the side wall 2 and / or 3 from done outside. As a result, the side wall 2; 3rd generated by the rotating paint roller 2 hydrodynamic forces are applied to bending. These bending stresses can be generated by means of Strain gauges 49 are detected and evaluated. They are a measure for evaluating whether the paint roller 2 turns. This can also be done via the strain gauges 49 determined in a different way. Because it can also from the signals of the strain gauges Vibrations are electronically evaluated by the the rotating paint roller 2 excites the bending plate 51.
