Definitions
- the invention relates to an inking unit for a rotogravure printing press according to the preamble of claim 1.
- a generic inking unit for a rotogravure printing press has become known from US-A-18 43 048.
- the inking unit consists of a lifting and lowering ink tray, a forme cylinder, a inking roller, which is rotatably mounted on a lever and is in rolling contact with the forme cylinder.
- the inking roller is arranged so that it can be brought into rolling contact in a lower, part of the forme cylinder facing the printing ink.
- a force can be introduced via the lever so that the inking roller can be pressed against the forme cylinder.
- the inking roller is arranged at a lateral distance from a vertical plane which passes through the axis of rotation of the forme cylinder.
- the form cylinder cannot dip into the printing ink, it can only be inked using the inking roller.
- Gravure inking units with inking rollers are e.g. B. become known from DE-PS 2 48 463.
- the inking roller transports ink against the gravure cylinder.
- DE-GM 72 29 629 is a device for adjusting the height of an ink tray to the forme cylinder.
- the invention has for its object to provide an inking unit with a inking roller for a rotogravure printing press, in which it is possible to keep the contact pressure of the inking roller on the forme cylinder and the preselected immersion depth of the forme cylinder in the intaglio ink even if one after the other Forme cylinders with different diameters can be used.
- the advantages that can be achieved with the invention also include the fact that a constant contact pressure (kg / m2) of the inking roller on the forme cylinder even with one large format variability of the forme cylinder (e.g. smallest diameter to largest diameter, such as 1: 2) can be set and maintained.
- a constant contact pressure (kg / m2) of the inking roller on the forme cylinder even with one large format variability of the forme cylinder (e.g. smallest diameter to largest diameter, such as 1: 2) can be set and maintained.
- the immersion depth of the forme cylinder can be changed without the contact pressure of the inking roller on the forme cylinder changing unaffectedly.
- the contact pressure (line pressure) can be changed sensitively and also changed while the machine is running, without having to change the immersion depth of the forme cylinder in the printing ink.
- a inking roller 3 and a forme cylinder 4 are immersed in an ink fountain 2 filled to the brim with gravure ink 1.
- the forme cylinder 4 dips to a pre-selectable depth.
- B. a few centimeters in gravure ink 1 (immersion depth T).
- the inking roller 3 is covered on its outer surface with a textile cover and is laterally spaced z. B. right (distance 12) from one vertical plane through the axis of rotation 11 of the forme cylinder 4 below in frictional contact with the jacket of the forme cylinder 4.
- the inking roller 3 is in a first end 10 of a one-armed lever arm 5 and a first end 7 of an angled two-armed lever arm 6, which over the left wall of the Protrude paint tray 2, rotatably mounted.
- a one-sided piston rod 13 of a single-acting cylinder 14 is articulated to a second end 8 of the two-armed lever arm 6 via a pin 9 and fork head.
- the cylinder 14 can be pressurized via a connection 15 on the rod side by means of a pneumatic or hydraulic medium.
- the pressure can be set via pressure sources (compressor, pump) and manual valves or pressure reducers not shown.
- a counter bearing of the cylinder 14 is articulated to a support piece 16.
- the support piece 16 is welded on the outside to the bottom plate 17 and is on the left beyond the outline of the paint pan 2.
- Bores are provided in the kink 18 of the double-armed lever arms 6 and at the second end 20 of the one-armed lever 5, through which a spindle 19 passes and is welded to the lever arms 5, 6.
- the ends of the spindle 19 are rotatably mounted in bores of two spaced webs 21 (left and right).
- the webs 21 (left, right) are integrally connected to the floor panel 17 inside the paint trough 2 near the two side walls 22.
- the bottom plate 17 is positively connected to the outside in the middle with one end of a toothed rack 23.
- the rack 23 is displaceable in a guide which is fixed to the frame and is not shown, but is not rotatably mounted.
- a Pinion 24 is in engagement with the toothing of the rack 23 and is connected via a shaft 25 to a reduction gear with a stepping motor 26 and a counter 27.
- the counter 27 serves as an indication of the current height of the ink tray 2 and is to be used as a measure of the current immersion depth of the forme cylinder 4.
- the ink tray 2 can be raised or lowered and thus the immersion depth of the forme cylinder 4 in the printing ink 1 can be determined independently of the diameter of the forme cylinder 4.
- a pressure medium with variable pressure is supplied to the cylinder 14 via the connection 15. This makes it possible to selectively apply the contact pressure of the inking roller 3 depending on the position of the pressure setting device z. B. sensitive pressure reducer to change.
