Definitions

  • the invention relates to a device according to the preamble of the first claim.
  • Devices of this type have the task of transferring a color profile generated by a metering device on a duct roller surface to an ink roller of an inking unit. This is also the case with dampening systems, in which dampening fluid must be supplied to the dampening unit rollers.
  • dampening systems in which dampening fluid must be supplied to the dampening unit rollers.
  • so-called siphon rollers are used, which are mounted in rocker arms and set in a reciprocating motion by a control cam.
  • Such a device has become known from US Pat. No. 2,092,461.
  • the lifting movement is generated by a rotating groove curve in which a roller of the lifting drive lever runs.
  • This lifter drive lever is rotatably mounted on a shaft.
  • the lifting swivel lever is also mounted on this shaft.
  • the lifter drive lever and lifter pivot lever are coupled via a driver on the lifter pivot lever, which engages in a recess in the lifter drive lever.
  • the jack roller or the jack pivot lever can be adjusted by adjusting screws on the jack drive lever.
  • this device is very complex in its construction and, in order to be able to function properly, it must be set precisely on the adjusting screws, i.e. the set screws determine the position of the jack roller relative to the jack drive lever.
  • the groove curve must also be made exactly for this jack drive. Another use of the curve e.g. for the drive of the dampener is not possible or only with difficulty.
  • the invention has for its object to provide a lifter drive which allows the lifter to be driven from a control cam provided for several functions and thereby to ensure an exact setting or safe contact of the lifter roller with the ductor and inking unit roller. Furthermore, this device should be simple in construction and inexpensive to manufacture.
  • This type of design allows the use of only one lever for storage and pivoting movement, e.g. the lifting movement of the ink and dampeners can take place together from one control curve. Due to the spring-mounted jack roller bearing, it is possible that the roller running on the curve always lies against the curve.
  • the lifter roller bearing is resiliently mounted on both sides, so that any adjustment of the lifter roller bearing is not necessary when suitable springs are selected. In this case, too, the cam roller can always rest on the curve and unnecessary impacts that can then occur when lifting the roller are avoided.
  • each push rod 1 is guided in the area of the control curve 2 by bolts 3 and elongated holes 4 in its longitudinal axis.
  • the remaining end of the push rod 1 is articulated on a lever 5 which is firmly connected to a jack shaft 6.
  • a jack shaft 6 On this jack shaft 6 swivel levers 7 are attached, which receive the jack roller bearings 8.
  • the pivot levers 7 have a flat guide 9 as an elongated opening.
  • a pin 8.1 provided on the lifter roller bearing 8 is guided in this flat guide 9.
  • the push rod 1 of the corresponding lifter 10 is set to the high point of the control cam 2, so that the pivot lever 7 reaches its extreme position.
  • the lifter roller bearing 8 is then adjusted so that the lifter roller 10 fits snugly against an inking roller 12.
  • the lifting roller 10 bears against the ductor 13
  • the lifting roller 10 is resiliently mounted to the latter, which is why the pivoting lever 7 despite being open meet the jack roller 10 on the duct roller 13 can pivot a little further. This further pivoting then takes place against the force of the spring 14.
  • this spring 14 must not be so strong that the push rod 1 is lifted off the control curve 2.
