Definitions

the invention relates to a method and a device for emptying a wedge ink fountain of printing machines.
inserts for wedge ink boxes are known (DE 43 15 595 C2).
the inserts are inserted into the wedge ink box, the ink to be printed is filled into these inserts and the insert including the remaining ink is removed when the color is changed.
a disadvantage is the high effort for the inserts when changing the color.
Suction devices for residual ink from chamber doctor blade inking units are also known (DE 42 25 451); these suction devices are for colors that usually come from wedge ink boxes be printed, not applicable.
the object of the invention is to provide a method and a device for emptying a wedge color box without much effort.
FIG. 1 shows a wedge ink fountain 1 with a duct roller 2, the ink 4 to be printed being located in the wedge formed by an ink knife 3 of the wedge ink fountain 1.
Ink metering elements 5 act on ink knife 3 of wedge ink fountain 1, with which a gap s between ink knife 3 and duct roller 2 can be set.
the duct roller 2 is assigned a self-drive 6.
This self-drive 6 is designed as a motor and reversible in the direction of rotation.
Gearboxes which can be reversed in the direction of rotation and which are connected to the drive wheel train of the printing press can also be used as self-drives.
the printing operation direction of rotation 7, ie the direction of rotation with which the duct roller is driven in printing operation, is indicated by an arrow in FIG. 1.
the direction of discharge operation ie the direction of rotation with which the duct roller rotates in emptying operation, is indicated by a double arrow 8 featured.
the duct roller 2 is arranged in the ink lifter 9, which oscillates between the duct roller and a first roller 10 of the inking unit, not shown.
the inking doctor blade 2 is associated with an ink doctor blade 11.
This ink doctor blade 11 is arranged at a negative angle ⁇ with respect to a horizontal 12, that is, placed flat.
a boundary 13 is arranged on the rear edge of the ink wiper blade 11 and forms a ink reservoir 14 with the ink wiper blade 11.
FIG. 2 shows another embodiment, the change compared to FIG. 1 being restricted to the arrangement of the ink doctor blade 11 on the duct roller 2 and the formation of the ink reservoir 14.
the ink doctor blade 11 is positioned steeply against the duct roller 2, ie at a small angle ⁇ with respect to a vertical 15.
the doctor edge 16 of the ink doctor blade 11 is assigned a deflector plate 17 which leads to the ink reservoir 14 designed as a trough 18.
the ink doctor blade 11 is arranged extending over the length of the duct roller. It is also possible to use an ink doctor blade 11 which does not extend over the length of the duct roller. In this case, the ink doctor blade traverses, wherein the traversing movement can be coupled with the traversing movement of a color stirring device (not shown).
the existing ink metering elements 5 can also serve as the ink wiper blade 11, in which case a guide foil 20 is assigned to them to discharge the ink into the ink reservoir 14 (FIG. 3).
the doctor roller 2 is rotated counter to the printing mode of rotation 7 with the ink gap s open in the emptying operating direction 8, the residual ink located in the wedge ink fountain 1 is conveyed out of the wedge ink fountain and thus the wedge ink fountain emptied.
the ink conveyed out of the wedge ink fountain 1 is peeled off from the inking doctor blade 11 by the duct roller 2 and passed into the ink reservoir 14.
the ink reservoir 14 including the ink doctor blade 11 can be removed after this process.
the color gap is closed the duct roller 2 rotated in the emptying direction 8, the color from the wedge ink fountain 1 promoted and doctored by the ink metering elements 5 from the duct roller and via the guide film 20 arranged on the ink metering elements 5 into the one designed as a trough 18 Color reservoir headed.
