Definitions
- the invention relates to a color box separation according to the Preamble of claim 1.
- the color to be printed becomes from a color box on an ink fountain roller and from this one transferred to downstream inking rollers.
- the ink fountain roller do a color meter or dosing act together, so that the printing ink according to the color needs of the subject zonal be supplied differently.
- color box separators are used, which is the Divide volume of color box.
- EP 0 374 092 B1 shows a color box separator which from two parallel metal plates exists between which a plastic sealing element is placed and which about screw elements both against the color box bottom as well as against the ink fountain roller is pressed.
- These known device is relatively expensive, furthermore by the screw a high pressure against the Ink fountain roller and the bottom of the ink fountain box.
- the ink fountain roller is strongly braked, which is a corresponding burden of Drive of ink fountain roller conditionally. Further, it is not Exclude that due to the high stopping forces of the ink fountain and / or the ink fountain roller is bent so that there is no longer any exact color dosage.
- Object of the present invention is a color box separation according to the preamble of claim 1 to such expand, allowing a dense separation in constructive as simple as possible execution is obtained.
- the color box separation as an insertable into the color box, accurate to a partial circumference of the ink fountain roller and the ink fountain floor shaped plate is formed, which at its rear End of a part of the color box behind.
- the plate has a flexible sealing element in shape a glued rubber strip on. This is preferably self-adhesive and can after use or at Wear removed easily and by a new one Strips are replaced.
- the inking unit separating plate made of plastic or Plexiglas made and points one from the color box floor at the top tapered wedge-shaped profiling.
- This wedge shape is caused by the color box rotation on the Roll surface located color of the flanks of the plate weggerakelt and so can not between roller surface and slide plate.
- the color block separation according to the invention can be simplified To an existing one with respect to the ink fountain roller. or parked color box can be installed. This is the color box at the rear end, a bar mounted, under which then in the parked state of the Color box the correspondingly shaped plate of the color separation is inserted. By adjusting the color box to the ink fountain roller is the plate against the bar the ink fountain roller and the bottom of the ink fountain as well as the Area of color dosing pressed. Combined with the sealing material results in a tight seal.
- Figures 1 and 2 show an ink fountain roller 1, which in Clockwise direction is driven. Regarding the ink fountain roller 1 is a color box 2 on and off stored. In 1, the ink fountain 2 is set to the ink fountain roller 1, in Figure 2, the ink fountain 2 of the ink fountain roller 1 turned off.
- the bottom of the color box 2 as well as the area between Soil and the Farbdosierettin 3 is a plate 4 shaped which parked at color box 2 (Figure 2) in the Ink fountain 2 is inserted and by hiring the ink fountain roller 1 and the bottom of the ink fountain 2 is pressed.
- a bar 6 in the rear end of the ink fountain 2 is a bar 6 about the format width of the ink fountain 2 is extended, under which the plate 4 of the inking unit separation according to the invention is used.
- Figure 3 shows the plate 4 again in profile. recognizable the plate 4 is wedge-shaped from the bottom of the color box. 2 tapered upwards. With the surface of Ink fountain roller 1, the plate 4 has a wedge-shaped surface contact, so that upon rotation of the ink fountain roller. 1 a squeegee effect with respect to the surface Color results. So no ink can be in the contact area get between plate 4 and surface of the ink fountain roller 1.
- the density elements on the underside of the plate 4 as well the color dosing 3 opposite side are indicated in Figure 3.
