Definitions

  • the invention relates to a dampening system according to the preamble of claim 1.
  • a dampening unit is known from US Pat. No. 3,673,959 in which an application roller is mounted in levers which can be pivoted about frame bolts for the purpose of parking the application roller and are actuated for this purpose by pneumatic cylinders. Shields are mounted on both sides of the tenon of the applicator roller, each of which receives a rubbing roller and an intermediate roller in contact with the applicator roller. The intermediate roller also has contact with a roller that guides the dampening solution. To switch to a washing position, the intermediate roller can be pivoted to an inking roller when the friction roller is removed. Two additional working cylinders are required to pivot the shields. In addition, the dampening unit cannot transport cleaning fluid into the inking unit.
  • the invention is based on the object of designing a generic dampening unit in such a way that it can be switched between a position suitable for dampening and a position suitable for supplying the cleaning liquid using the rollers which are absolutely necessary for dampening.
  • the dampening unit comprises an applicator roller 1, a transport roller 2 and a feed roller 3.
  • the applicator roller 1 and the transport roller 2 expediently have an elastic surface, for example made of hard rubber or a comparable plastic, while the feed roller has a metallic, water-accepting surface, for example made of chromium.
  • the application roller 1 can cooperate with a forme cylinder 4 carrying the printing form.
  • the form cylinder 4 is supplied with ink via an inking roller 5 and an anilox roller 6.
  • the application roller 1 is rotatably supported at both ends in an arm 8 by means of an axis 7.
  • the transport roller 2 is rotatably seated on an axis 9, which is also mounted on the support levers 8 and secured against rotation.
  • the axis 9 has at each end an eccentrically arranged bearing pin 10, which is freely rotatable in a control lever 11.
  • the control levers 11 can be pivoted about fixedly arranged bushes 12, the longitudinal axes of which coincide with the longitudinal axis of a shaft 25 of the feed roller 3 driven by means of gears (not shown).
  • An actuating device 13 which can consist of a hydraulic or pneumatic piston or an electrically operated magnet, is used to actuate the actuating lever 11. With control device 13, the control lever 11 is pivoted about the bush 12 in or against the direction of arrow a.
  • the support lever 8 also carries a pin 14 on which the one end of a rocker 15 is pivoted.
  • the other end of the rocker 15 is articulated in the same way on a pin 16 which is attached to a side wall 17 on the printing press.
  • a trough 18 is provided below the application roller 1, into which a pump 19 is fed via a feed line 20 Can pump cleaning fluid from a reservoir 21. After completion of a washing process, the tub 18 can be emptied again via a return line 22. The cleaning liquid flows back through a filter 23 into the reservoir 21.
  • a spray device 24 is provided, with which dampening liquid can be sprayed onto the feed roller 3.
  • the dampening liquid passes from the feed roller 3 via the transport roller 2 and the application roller 1 to the forme cylinder 4.
  • the actuating device 13 is actuated and thereby rotates the control lever 11 in the direction of arrow a around the bushing 12. This pivoting movement is followed by the journal 10 with the axis 9 As a result, the support lever 8 is moved approximately in the direction of arrow b.
  • the rocker arm 15 ensures that the application roller 1 moves on a predetermined path to the tub 18 and the transport roller 2 to the inking roller 5. If the rollers 5, 6 are now driven, the transport roller 2 and the application roller 1 are entrained by friction and thus cleaning liquid is conveyed to the ink application roller 5.
  • the transport roller 2 Due to the eccentricity between the axis 9 and the bearing journal 10, the transport roller 2 is further lifted off the feed roller 3 when it is switched to the washing position shown in FIG. 2. This lifting is expedient so that after the washing is finished, no residues of the cleaning liquid remain on the feed roller 3, which can negatively influence the subsequent dampening of the forme cylinder 4. With lower requirements for immediate further printing after the washing process, the eccentricity between the axis 9 and the bearing journal 10 can be dispensed with, so that the feed roller 3 remains in contact with the transport roller 2 even during washing.
  • the applicator roller 1 and the transport roller 2 are each attached to a carrying lever 26 at each end stored.
  • the support lever 26 is in turn rotatably mounted on the control lever 11 by means of the bearing pin 10. 1 to 3, a control cam 27 is provided on each support lever 26 instead of the rocker 15.
  • Each cam 27 interacts with a pin 28 attached to the side wall of the printing press.
  • the control levers 11 are pivoted in the direction of arrow a around the bushes 12.
  • the control lever 11 in turn take about the bearing pin 10, the eccentrically arranged axis 9 and the support lever 26, which are secured against rotation on the axis 9, approximately in the direction of arrow b.
  • the movement of the support levers 26 is predetermined by the interaction of the control cams 27 with the pins 28.
  • each control cam 27 is a control slot which engages over a pin 28.
