Definitions

  • the invention relates to a dampening solution metering device for the dampening system of a printing press, in particular an offset printing machine, with a roller carrying a dampening solution layer and arranged in a dampening solution container, from which liquid is transferred to the subsequent dampening unit roller by means of zone-wide, pivotable, spaced apart dampening solution metering disks.
  • the object of the present invention is to provide a dampening agent metering device of the type mentioned at the outset which is compact in construction, in which an individual control of the dampening agent metering disks is possible indefinitely and in which the dampening agent metering disks contribute to the distribution of the dampening film on the downstream dampening unit roller.
  • the surface speed of the water tank roller 2 is said to be identical to that of the machine speed, which is why it is advantageous to use spray orifices 1 ', for example in the form of sheet metal or plastic plates, to avoid the risk of splashing.
  • spray orifices 1 ' for example in the form of sheet metal or plastic plates, to avoid the risk of splashing.
  • the need for dampening solution in the individual zones is transferred from the water tank roller 2 to a further roller 5 by means of dampening agent metering disks in the form of disks 4 which extend in the axial direction and are spaced apart from one another.
  • this further roller 5 is simultaneously the first inking roller and a traversing roller.
  • dampening agent metering disks 4 The advantageous placement of the dampening agent metering disks 4 on the water tank roller 2 is described below with reference to FIGS. 2 to 7.
  • each dampening agent metering disk 4 is arranged next to one another in the axial direction of the rollers 2, 5 and are spaced apart from one another by spacer bushings 8 ′.
  • Each dampening agent metering element 4 is rotatably held on at least one - but preferably two - approximately angular pivot levers 6.
  • One end of the pivot lever 6 is pivotably arranged on a fixed shaft 8.
  • the other end of each pivot lever 6 is connected to a control device, preferably a reciprocating piston.
  • a pneumatically actuated reciprocating piston is provided from the piston 9 and the cylinder 10 comprising them.
  • the piston 9 can be moved in a special way along the path Y and pivoted by means of a bearing 11.
  • the stroke movement of the piston 9 is adjustable by nuts 12, 13.
  • the degree of the contact force for the dampening agent metering disc 4 in the direction of the roller 3 is determined by the air pressure in the cylinder 10.
  • a dampening solution metering disk 4 is rotatably arranged on a pin 15, while the piston rod 14 is connected to one end of the swivel lever 6 via a pin 16.
  • the pivot levers 6 can each be arranged on the shaft 8 via eccentrics.
  • the cylinder 10 is advantageously pivotally arranged in the bearing 11.
  • bearing pins 18, 19 are provided on both sides of the cylinder 10, which are preferably arranged in a common comb strip 17.
  • the bearing journals 18, 19 are covered by a bearing cover 20.
  • the supports 21 serve to receive the bearing pins 18, 19.
  • FIG. 7 shows a clock generator 23 which can be controlled in the desired manner, for example by means of a computer, in accordance with the color requirement in the respective color zone.
