Definitions

the invention relates to an inking unit for a rotogravure printing press according to the preamble of claim 1.
US-PS 51 03 723 shows an inking unit with a inking roller for an intaglio printing machine and a mechanism for adjusting the height of an ink tray relative to the forme cylinder.
the inking roller is pressed against a forme cylinder by means of a lever system and a working cylinder.
the contact force of the inking roller against the forme cylinder corresponds to the length of the forme cylinder can be preset.
the same applies to a changing immersion depth or a different diameter of the forme cylinder.
the inking roller 3 is rotatably received at first ends 7 by lever arms 8 mounted fixed to the ink tray. Second ends 9 of the lever arms 8 are detachably connected to a first end 11 of a torsion bar spring 12.
the torsion bar spring 12 can have a hexagonal cross section.
the first end 11 of the torsion bar spring 12 is non-positively and positively connected to a first end 14 of a sleeve 13 having a hexagon socket.
the sleeve 13 has at its second end 16 an external thread which is operatively connected to a threaded bore in the second end 9 of the lever arm 8. Between its two ends 14, 16, the sleeve 13 is mounted in a bearing block 17 which is fixed to the paint tray.
the bearing block 22 forms, together with the cross member 23, an abutment for a positive and form-fitting reception of the second end 21 of the torsion bar spring 12 Ink tray with the inking roller 3 arranged therein is movable in the vertical plane 6.
the supports 27 are designed as racks analogous to the design in US Pat. No. 5,103,723.
the support 27 is displaceable in a guide which is fixed to the frame, not shown, but is not rotatably mounted.
a pinion of a drive, not shown, is in engagement with the toothing of the rack and is connected via a shaft to a reduction gear with a stepping motor and a counter.
the counter 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. All previously mentioned parts 7 to 27 are present in duplicate and can be mirrored according to the partial top view according to FIG. 2 on a horizontal center line 28 running transversely to the axial direction of the inking roller 3.
the inking roller 3 can be preset according to the width of the forme cylinder 4 and its diameter in terms of its contact force by means of both torsion bar springs 12.
the bearing block 17 has a bore running in the axial direction of the inking roller 3 for receiving a dowel pin 29, which limits the upward movement of the pretensioned lever arms 8, in particular when the ink pan 2 with the inking roller 3 is vertical has moved downwards, e.g. B. when changing the forme cylinder 4.
the slot 31 located in the lever arm 8 extends in the direction of the vertical plane 6.
