Unser Zeichen: R 1256 DEOur reference: R 1256 DE PatentansprüchePatent claims 1. Einfärbevorrichtung für die Zufuhr von Druckfarbe an eine Presse, welche eine Druckwalze mit einer Vielzahl von gleichzeitig einzufärbenden Druckspalten enthält, wobei die Vorrichtung aufweist:1. Inking device for supplying printing ink to a press which contains a printing roller with a plurality of printing columns to be inked simultaneously, the device comprising: a. eine Farbzufuhr;a. a paint supply; b. eine volumetrische Pumpe für Farbe mit einer Einlaßseite und einer Auslaßseite, wobei die Einlaßseite an die Farbzufuhr angeschlossen ist;b. a volumetric pump for paint having an inlet side and an outlet side, the inlet side being connected to the paint supply; c. eine angrenzend an die Druckwalze positionierte Farbschiene mit einer Farbaustrittsöffnung, welche für die Farbzufuhr an jede Druckspalte eingestellt ist;c. an ink rail positioned adjacent to the printing roller with an ink outlet opening which is adjusted for supplying ink to each printing column; d. eine Einrichtung zur Farbleitung, welche die Auslaßseite der Pumpe mit jeder Austrittsöffnung in der Farbschiene verbindet;d. a paint line means connecting the outlet side of the pump to each outlet opening in the paint rail; e. eine Ventileinrichtung, welche innerhalb der Farbleiteinrichtung zwischen der Pumpe und der Farbschiene angeschlossen ist und der Farbe gestattet, in zeitlich ge-e. a valve device which is connected within the paint guide device between the pump and the paint rail and allows the paint to be steuerten Entladungen von der Pumpe zu der Schiene zu fließen;controlled discharges to flow from the pump to the rail; f. eine Bypasseinrichtung, um Farbe von der Ventileinrichtung an eine stromaufwartige Stelle des Pumpeinlasses zu leiten; undf. a bypass means for directing paint from the valve means to an upstream location of the pump inlet; and g. eine Steuereinrichtung zum Regeln des Ventilbetriebs, um dosiert Farbe an die Farbleiteinrichtung und an die Bypasseinrichtung abzugeben.g. a control device for regulating the valve operation in order to deliver metered amounts of paint to the paint guide device and to the bypass device. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Steuereinrichtung eine Einrichtung zum optischen Lesen aufweist, welche ein die Druckdichte in einer Spalte darstellendes Signal startet, und einen Magnetschalter für die Ventileinrichtung, welcher auf das Signal von der optischen Lesseinrichtung anspricht, um den Farbfluß zu pulsen.2. Apparatus according to claim 1, characterized in that the control device comprises an optical reading device which starts a signal representative of the print density in a column, and a magnetic switch for the valve device which responds to the signal from the optical reading device to pulse the flow of ink.
3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß die Steuereinrichtung das Öffnen der Ventileinrichtung bewirkt und damit der Farbe gestattet, wahrend Zeitintervallen an die Farbschiene zu fließen, deren Dauer folgender Gleichung genügt:3. Device according to claim 2, characterized in that the control device causes the valve device to open and thus allows the paint to flow to the paint rail during time intervals whose duration satisfies the following equation: N
TAN = TMIN~
N
T AN = T MIN~
T = vorgewählte Offenzeit der Ventileinrichtung;
N = prozentuale Farbüberdeckung ^ 50 %.
T = preselected opening time of the valve device;
N = percentage color coverage ^ 50%.
4. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, daß die Steuereinrichtung das Öffnen der Ventileinrichtung bewirkt und damit der Farbe gestattet, wahrend Zeitintervallen an die Farbschiene zu fließen, deren Dauer folgender Gleichung genügt:4. Device according to claim 2, characterized in that the control device causes the valve device to open and thus allows the paint to flow to the paint rail during time intervals whose duration satisfies the following equation: OQ &Ggr; &igr;' &Ggr;" &rgr; r>OQ &Ggr;&igr;'&Ggr;"&rgr; r> 1-&Ngr;1-&Ngr; TAUS = &Mgr;&Igr;&Ngr; T OFF = μ�Igr;�Ngr; T = vorgewählte Offenzeit der Ventileinrichtung;T = preselected opening time of the valve device; N = prozentuale Farbuberdeckung &uacgr; 50 %.N = percentage color coverage &uacgr; 50%.
