Definitions
- the invention relates to a method and a device for the ink supply of pasty printing inks on printing presses.
- Ink feeds on printing presses are known (DE-PS 30 30 774), which contain an ink fountain, a duct roller and a plurality of ink metering elements on the underside of the fountain which follow one another along the duct roller and form a variable ink gap.
- the pasty printing ink is poured into the open, wedge-shaped ink supply space formed by the underside of the ink fountain including ink metering elements and a doctor roller.
- Color storage space has been reduced and carried out in a closed design.
- the object of the invention is to provide a method and a Ein ⁇ chtung for ink supply with improved dosage and low cleaning effort.
- 1 is a device for ink supply in an open design
- Fig. 2 shows a device for ink supply in a closed design.
- a ink fountain 1 in a known open design is assigned a duct roller 2 and the ink fountain contains a plurality of ink metering elements 3 on the underside of the ink fountain 1 which follow one another along the ink fountain roller 2 and form a variable ink gap (FIG. 1)
- each ink zone is assigned an ink metering element 3.
- the ink fountain 1 is designed as an open ink fountain and contains only a minimum ink quantity 4.
- the minimum ink quantity is understood to be the ink quantity that is used to supply the ink, i.e. to wet the duct roller and to maintain a defined hydrodynamic pressure in the ink fountain , absolutely necessary
- the surface 5 of the minimum color quantity 4 is assigned a level controller 6, which detects the fill level or the level of the minimum color quantity 4 and, if the specified minimum color level is undershot or exceeded, initiates corresponding control steps - increasing or decreasing the minimum color quantity - or generates warning messages 2 is assigned at least one supply system 7 for the quantity of consumable ink 8
- Consumable ink quantity 8 is understood to mean the quantity of ink that is necessary for inking the printing form for the respective print job, that is to say the amount of consumable ink 8 supplied corresponds to the quantity of ink that is consumed when the printing form is inked and ultimately when the ink is applied to the printing material
- a feed system 7 is expediently assigned to each of the two successive ink zones along the duct roller 2 or each ink zone group
- a single feed system 7 is arranged traversing along the duct roller 2 according to an embodiment not shown, the level controller 6 being expediently assigned to the only traversing feed system 7
- the feed system 7 and / or the level controller 6 is assigned to a known traversing color stirring system
- Each feed system 7 is connected to an ink supply system (not shown) and contains a metering unit 9 and a pressure switch unit 10 ) determined or obtained from prepress data (CIP3) or from empirical values.
- the control of the consumption color quantity 8 is also via the level query of the minimum color quantity - increased minimum color quantity means excess consumption. Color quantity, so a reduction of the consumption color quantity is necessary or too little minimum color quantity means too much supplied consumption color quantity, thus an increase of the consumption color quantity is necessary - possible
- the duct roller 2 is a lifter 11 and this is followed by a friction roller 12 of a known inking unit, not shown
- Lifter 11 is used to increase responsiveness - faster transport of paint
- washing liquid 13 is applied to the duct roller 2 via a washing device 13
- FIG. 2 shows a device for supplying paint in a closed design
- the minimum amount of color 4 is in a reduced and closed
- the minimum amount of ink 4 is not monitored by a level controller 6 but by a pressure monitor 14 in the ink supply line 15
