Definitions

the invention relates to a metering roller for a film dampening unit of an offset rotary printing press according to the preamble of the claim.
a dampening unit for a lithographic printing machine with at least one dampening solution application roller is known, by means of which the dampening solution can be applied to a plate cylinder and a roller or dampening solution duct connected upstream of the dampening solution application roller has become known.
the metering roller can be skewed relative to the dampening agent application roller or the dampening solution ductor for the purpose of dampening solution metering, the diameter at the ends of the metering roller being larger than in its central region.
the invention has for its object to provide a metering roller for a dampening system, the Dampening solution metering is repeatable depending on the print order.
each print job can be repeated at any time with the same print quality and without great loss of time or waste.
a dampening unit consists of a dampening agent application roller 2 interacting with a plate cylinder 1, a dampening solution duct 3 and a metering roller 4 that can be adjusted to the dampening solution 3 pivoted levers 7 and can be turned by turning eccentric bushings 8 in their distance a between the journal 6 of the dampening solution 3 and the journal 9 of the metering roller 4 can be set.
the sleeve 8 is positively connected to a first end of a lever 11, while a second end of the lever 11 is connected in an articulated manner to a motor-gear unit 12 with an integrated position indicator or potentiometer 13.
the motor-gear unit 12 is articulated between an end of the lever 7 remote from the dampening medium and said lever 11.
the dampening solution duct 3 is immersed in a dampening solution container 15.
a motor-gear unit 16 with an integrated position indicator or potentiometer 17, which is articulated between the end 7 of the lever 7 carrying the metering roller 4 and a side frame 14, with an integrated position indicator or potentiometer 17, each lever 7 can be pivoted and thus the metering roller 4 can be tilted with respect to the dampening unit 3.
the diameter of both ends of the metering roller 4 can be larger than the diameter of the central region of the metering roller 4.
Each of the parts 6 to 9, 11 to 14 and 16, 17, 19 and 21 is provided twice, ie separately for each end face of the dampening solution 3 or the metering roller 4, but only shown once in the drawing and labeled only once.
Each potentiometer 13; 17 of the motor gear units 12; 16 is for the purpose of position feedback with a z. B. in Machine control station existing computer 18 connected, while the computer 18 with each motor-gear unit 12; 16 via an amplifier 19; 21 communicates.
a strip-shaped dampening solution thickness control device 22 which scans the surface of the dampening solution 3 in the direction parallel to the axis is connected to the computer 18 and its memory 23 and transfers information about the amount of dampening solution transferred from the metering roller 4 to the dampening application roller 2 by means of the dampening solution 3.
the computer 18 is also connected to a higher-level controller or keyboard 24 for the purpose of entering control commands and to a monitor 26.
a plurality of dampening agent thickness control devices 22 spaced apart from one another in the axis-parallel direction of the dampening solution duct 3 are provided.
the distance a and thus the contact pressure of the metering roller 4 on the dampening solution 3 is preset according to the printing requirements by means of the keyboard 24.
a different amount of dampening solution over the length of the dampening solution generator 3 can be preset by means of the motor drive unit 16 due to the separate inclination of the levers 7.
the dampening agent thickness control devices 22 arranged in the axis-parallel direction to the dampening agent duct 3 are guided the measurement results to the computer 18, the actual values being compared with the target values on the monitor 26 and, if necessary, a correction being able to be initiated using the keyboard 18.
the stored dampening solution values per print job can be called up at any time from the memory 23 of the computer 18 for repeat jobs and used for metering the amount of dampening solution.
