Definitions
- the invention relates to a method for cleaning a doctor blade device for a flushing inking unit of a rotary printing press, from a doctor blade carrier provided with a longitudinal groove, on the two parallel to one another on an inking roller adjustable doctor blades that are attached together with the inking roller, the channel of the doctor blade carrier and an ink chamber at the end of the sealing means provided limit from lines for feeding and discharging the paint in the ink chamber and out of it and out of adjustment devices for pressing the doctor blade holder onto the inking roller there is, after pumping the paint out of the paint chamber this is rinsed with a solvent.
- the object of the invention is therefore a method of the beginning specified type to create, after in simple and thoroughly remove all paint residues not only from the ink chamber the doctor blade device, but also from the supply and discharge lines have it removed.
- this object is achieved in a method of the beginning specified type solved in that the color from the ink chamber via the discharge line or lines back into the Color tank is pumped that subsequently from a solvent tank via the feed line or lines from a solvent tank Solvent pumped into the paint chamber and over the drain lines in for a predetermined period of time the paint tank is routed, that then by paint contaminated solvents for a predetermined period of time is pumped into a dirt tank that the Solvent supply from the solvent tank is interrupted and the solvent is pumped into the dirt tank that then fresh solvent via the feed line into the Ink chamber pumped, the suction line to the solvent tank closed and the solvent via the supply and discharge lines in a closed rinse cycle for a specific one Time is pumped and then that in the cycle conveyed solvent is fed into the dirt tank.
- the individual steps for cleaning the doctor device and the associated lines can be carried out one after the other, the cleaning process being controlled by a computer can.
- the solvent which is still heavily enriched with color, into the paint tank headed because the resulting thinning of the paint one more can be accepted and excess
- the solvent evaporates again.
- the further process steps aim at once a thorough cleaning of the To reach doctor blade device and secondly an economical To ensure solvent consumption because that is in the dirt tank directed and color-enriched solvents especially must be disposed of.
- the color of the ink chamber is expediently replaced by an in the middle of the feed line is fed in and through side discharge lines sucked out of this again.
- Embodiment of the invention provided that during the rinse phases the inking roller with one opposite Printing operation is driven at higher speed. This higher Speed causes higher turbulences that favor cleaning.
- the direction of rotation is expedient during the rinsing phase the inking roller one or more times reversed.
- a printing unit 1 which consists of a Impression cylinder 2, a pressure roller 3 that can be set on it and an anilox roller 4 which can be set on the printing roller.
- a doctor blade carrier 5 is adjustable, the consists of a profile bar.
- the bar of the doctor blade holder 5 is provided with a groove forming the interior of the ink chamber.
- the printing ink flows into this channel in the middle area feeding hole 6.
- holes 7, 8 for removing the ink.
- the end faces of the channel edges of the doctor blade carrier are in opposite directions sloping roof-shaped. Are on these end faces Doctor knife attached, the dingy or brushing on the anilox roller 3 are adjustable. On the sides of the doctor blade holder seals are arranged opposite the interior of the ink chamber seal the anilox roller 4.
- Doctor devices of this type are, for example, from the German Patent applications 195 16 223.4 and 195 16 224.2 known to which reference is made for a more detailed description of the doctor device becomes.
- the feed hole 6 in the profile bar of the doctor blade carrier 5 is through a line 10 to the pressure side of a pump 11, which is preferably a piston pump, connected.
- the suction side of the pump 11 is connected through a line 12 connected to a further pump 13, the suction pipe in a solvent tank 14 protrudes.
- the holes 7, 8 are through lines 15, 16 with the suction sides connected by pumps 17 coupled together.
- the printed pages the pumps 17 are optionally via valves 18, 19 a line 20, which opens into the ink tank 21, and with the line 22 connectable, which opens into the dirt tank 23.
- a check valve 24 is arranged in line 12.
- the return lines 15, 16 are connected to one another by a line 30 connected.
- a valve 31 is arranged in the feed line 10, through which the line 10 optionally on the bore 6th or the line 30 is convertible.
- a valve 32 is arranged through that the pressure side of the pump 11 with the suction side of the pump 17th is connectable.
- valves 18, 26 the pressure sides of the valves 17 are included the suction side of the valve 11 connectable.
- the valves 18, 19, 26, 31 and 32 are controllable Directional control valves, for example around solenoid valves. That too Check valve 24 is remotely controllable.
- valves and pumps are operated by a control device, not shown controlled with a computer so that the pumps and valves can be operated according to predetermined programs.

Description
Während des Druckbetriebes ist das Sperrventil 24 gesperrt und die Pumpe 11 ist über das Wegeventil 26 mit dem Saugrohr 27 verbunden, so daß sie aus dem Farbtank 21 Farbe über die Leitung 10 und das Ventil 31 über die Zuführungsbohrung 6 in die Farbkammer fördert. Aus der Farbkammer werden über die Abführleitungen 15, 16, die Pumpen 17 und die Wegeventile 18, 19 die Druckfarbe über die Leitung 20 in den Farbtank 21 zurückgepumpt.
