Definitions

the invention relates to an ink fountain with an automatic ink supply for printing presses.
the sheet-like ink supply of the individual printing towers is on sheetfed offset printing machines in a wedge color box, which adjoins a duct, with adjustable zones Color dosing elements.
the dosing elements form an inlet gap to the duct through which the color task is regulated.
the ink fountain of the machine is used to prepare for printing filled with a color supply.
Ink supply devices are also known (DE 43 39 939 C2), in which the wedge-shaped ink supply space has been reduced in size and has a closed design. The ink is supplied to the reduced and closed ink supply room by means of color cartridges.
the disadvantage of this device is that there is inadequate or inadequate coloring and the degree of automation is low.
the object of the invention is to provide an automatic ink supply including a needs-based coloring.
the invention is explained in more detail below using an exemplary embodiment.
the drawing shows an ink fountain with automatic ink supply.
a duct roller 1 is assigned a lower part 2 of a known wedge ink fountain, wherein on the lower part 2 ink metering elements 3 for setting a gap in relation to the duct roller 1 are arranged.
an ink fountain insert 4 is placed and between the lower part 2 and the bottom 7 of the ink fountain insert 4 is for sealing a flat gasket 5 is arranged.
the bottom 7 of the ink fountain insert 4 is at least a fastening screw 6 detachably connected to the lower part 2.
a color distribution element 8 is firmly connected to the underside 7 of the ink fountain insert 4.
the ink distribution element 8 has an end face 9 that is operatively connected to the duct roller 1. According to a first variant, the end face 9 does not touch the duct roller 1, ie there is a small gap and, according to a second variant (not shown), the end face 9 of the ink distribution element 8 touches the duct roller, for example via a rotating element.
the front side 9 and the ink metering elements 3 enclose an ink supply space 10 in connection with the underside 7 of the ink fountain insert 4.
a connector 11 for the ink supply to the ink supply space 10 is arranged on the ink distribution element 8.
the ink is supplied from connection 11 to the ink supply space 10 via at least one ink distribution channel 12, it being possible for additional ink distribution channels 12 to be arranged across the width of the ink fountain.
a pressure sensor 13 is arranged in the color distribution channel 12.
the connection 11 is connected to a paint cartridge or via a metering valve 14 to a paint supply system 15.
the pressure sensor 13 is connected to the metering valve 14 via a pressure switch 16. If the pressure in the ink supply space 10 drops when there is not enough color, the pressure sensor 13 and the pressure switch 16 - pressure sensor 13 and pressure switch 16 can also be combined in one structural unit - a signal is fed to the metering valve 14 and the ink supply space 10 is supplied with color again.
connection 11 of the ink distribution element 8 is separated from the ink supply system or from the ink cartridge, if it is not part of the ink fountain insert, the fastening screw is loosened and the ink fountain insert 4 is removed from the wedge ink fountain.
the removed unit can now be cleaned outside the printing press, and the ink supply space is also easily accessible.
