Definitions

  • the invention relates to an ink fountain according to the preamble of claim 1.
  • Ink fountains for printing machines are generally known. From DE-OS 2814889 an ink fountain is known which contains an ink fountain roller coming into contact with printing ink and a plurality of laterally arranged side by side, in the longitudinal direction of the circumferential surface of the ink roller in direct contact with one another, held in the bottom of the ink fountain, pivoted, held ink metering elements, which with a pivot lever are positively connected, a controllable mechanism being provided in order to be able to set a gap formed by the individual ink metering elements and the surface of the ink fountain roller.
  • the ink guide surfaces of the ink fountain base and ink metering elements are always at an angle which is slightly above 90 °, which makes cleaning the ink fountain difficult.
  • a base plate of an ink fountain floor scrapes off the ink guide surface of the ink metering element when the ink metering element moves in the direction of “more ink”, experience has shown that it cannot be avoided that ink particles get under the base plate and negatively affect the smoothness of the ink metering element.
  • the invention has for its object to provide a pivotable ink metering element, whose one color guide surface with a color metering extension extends into a space of an ink fountain that can be filled with printing ink, in which a pivoting movement of the ink guide surfaces from ink metering elements to the ink fountain color guide surface is made possible.
  • an ink fountain floor 2 is provided, the inner bottom surface 3 of which is covered with printing ink when the ink fountain 1 is filled with a printing ink.
  • a ceramic-coated ink fountain roller 4 which is driven in a known manner, is immersed in the ink fountain 1. It forms a paint passage gap with a paint metering attachment 5 of a paint metering element 6.
  • the ink fountain base 2 expediently extends as an extension of the base surface 3 beyond the ink metering elements 6 as an end piece 7 with the end surface 8.
  • a longitudinal pit 9 is worked into the ink fountain base 2 from the base surface 3.
  • a left guide surface 12 of the longitudinal pit 9 collides with the base surface 3 at an angle a, which is preferably less than 90 °, but can also be 90 °.
  • An edge created at a collision point between the left guide surface 12 and the base surface 3 serves as a pivoting edge (line) 21 for the ink metering elements 6.
  • a right guide surface 11 runs parallel to the left guide surface 12 of the longitudinal pit 9, a base surface 10 of the longitudinal pit 9 runs at a distance « a and parallel to the bottom surface 3 of the ink fountain base 2.
  • Vertical openings 13 in the ink fountain base 2 open into the base surface 10 of the longitudinal pit 9 and extend over an entire length «b of the ink fountain base 2 covered with ink metering elements 6 at a distance of z. B. 30 mm apart.
  • a cross section of the openings 13 is so large that a pivot arm 17 which is positively connected to the horizontally extending ink metering element 6 can be moved sufficiently.
  • the swivel arm 17 carries out a preselectable swivel movement. For this purpose, it is provided in its lower part with an elongated hole 18 into which a crank pin 19 driven by an electric motor engages.
  • a swivel edge 21 of the swivel arm 17 lies on an intersection of the guide surface 12 with the bottom surface 3 of the ink fountain base 2.
  • the swivel edge 21 for the swivel arm 17 is also the swivel edge for the swivel arm 17 is also the swivel edge for the ink metering element 6.
  • the bottom surface 3 of the ink fountain base 2 continues in a color guide surface 22 of the ink metering element 6 without a groove or increase in the transition between the two surfaces 3; 22 bothers.
  • the ink guide surface 22 first takes a straight course, which then merges into a concave curvature which ends in an ink metering attachment 5.
  • a vertical surface 24 of the ink metering element 6 forms an angle ⁇ of approximately 90 ° with its ink guide surface 22 and ends in FIG a first support lug 26.
  • the support lug 26 projects approximately 1 mm beyond a curved rear surface 27 of the ink metering element 6.
  • a neck 28 of the swivel arm 17 opens into this rear surface 27.
  • the rear surface 27 ends in a second support shoulder 29. While the first support shoulder 26 is supported on the base surface 10, the second support shoulder 29 is supported on the right guide surface 11 of the longitudinal pit 9.
  • the support lugs 26, 29 each preferably extend over an entire length “c of the ink metering element 6 and form an angle y of approximately 80 ° with one another.
  • the support lugs 26, 29 can have a rectangular cross-section, their support surfaces 14, 15 as end faces should be as narrow as possible.
  • the support lugs 26, 29 can also be designed in the form of a cutting edge, with a straight face or with a round face.
  • An expansion bore 30 is made centrally to each opening 13 from the side facing away from the bottom surface 3 of the ink fountain 1.
  • a flat bore base 31 of the extension bore 30 forms a force application surface for a conical compression spring 32, which is attached to the pivot arm 17. It is clamped between the abutment surface - the bottom of the bore 31 - and the ends of a pin 33 projecting over the cross section of the pivot arm 17 and positively connected to the pivot arm 17.
  • the two support lugs 26, 29 and thus the ink metering element 6 are pressed against the by the compression spring 32 Base 10 or the right guide surface 11 of the longitudinal groove 9 drawn.
  • the seal against the ink fountain base 2 is carried out by pressing the edge of the sealing membrane 34 against the bottom of the bore 31 by means of the compression spring 32.
  • a narrow one is in a back 16 of the ink metering element 6, above the second support projection 29 .
  • Longitudinal groove 36 extending over the entire length «c of the ink metering element 6 is provided for receiving a first lateral edge 38 of an elastic sealing strip 37.
  • a second lateral edge 35 of the elastic sealing strip 37 is connected in a sealed manner to the end face 8 of the ink fountain base 2.
  • the sealing strip 37 extends in one piece over the entire length “b of the ink fountain base 2, that is to say over all ink metering elements 6 of an ink fountain 1 arranged next to one another.
  • each of the vertical surfaces 24 of the ink metering element 6 there is an axially parallel groove 39, which extends over the entire length “c” of the ink metering element 6, at a distance of about 1 mm from the ink guide surface 22. It serves to accommodate an elastic sealing cord 41, e.g. The sealing cord 41 extends in one piece over the entire length “b *. The dimensions of the sealing cord are such that in each operating position of the ink metering elements 6, the left guide surface 12 of the ink fountain base 2 against the vertical surface 24 of the ink metering element 6 is securely sealed.
  • a lubricant eg. B. fat
  • each color metering element 6 is provided with a through hole 44 in its center. It ends on both end faces 45, 46 in a lubrication channel 47, 48. These each run within the area boundary of the end faces 45, 46 and are approximately 10 mm long, 2 mm wide and 0.5 mm deep.
  • patent protection is applied for for an ink fountain for a printing press with an ink fountain roller that dips into the ink fountain and a large number of individually operable ink metering elements arranged side by side in close proximity to one another in an ink fountain floor, each of which is provided with a pivotable swivel arm.
  • ink metering elements form a changeable ink metering gap with a peripheral surface of the ink fountain roller, characterized in that ink metering elements (6) in addition to their respective ink guide surfaces (22) projecting into the ink fountain (1) and an ink metering attachment (5) entirely in a covered cavity (43) Ink fountain base (2) of the ink fountain (1) are pivotally arranged that the Cavity (43) is completely filled with a lubricant.
  • patent protection is applied for for a method for maintaining smooth movement of ink metering elements of a ink fountain of a printing press, several individually adjustable ink metering elements being arranged close to one another, characterized in that a longitudinal bore (44) in the ink metering elements (6) a lubricant is pressed between the end faces (45, 46) of immediately adjacent ink metering elements (6) and for a device for carrying out the method, characterized in that ink metering elements (6) are provided with a continuous longitudinal hole (44) that the longitudinal holes (44) all color metering elements (6) are connected to each other.
