Definitions

  • the invention relates to an ink fountain according to the preamble of claim 1.
  • Ink boxes for printing machines are generally known.
  • an ink fountain which contains an ink fountain roller coming into contact with printing ink and a plurality of laterally arranged ink dosing elements which are arranged side by side and which are in direct contact with one another in the direction of the circumferential surface of the ink roller and which are pivotable in the base of the ink fountain. which are positively connected to a pivoting lever, a controllable mechanism being provided in order to be able to adjust a gap formed from the individual ink metering elements and the surface of the ink fountain roller.
  • the invention has for its object a pivotable color metering element, the one with a color guide surface to create an ink metering approach into a space of a 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 ink 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 ⁇ , which is preferably less than 90 °, but can also be 90 °.
  • An edge created at a junction of the left guide surface 12 and the base surface 3 serves as a swivel 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.
  • 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 ink metering element 6.
  • the bottom surface 3 of the ink fountain base 2 sits in a paint guide surface 22 Color metering element 6 continues without a groove or increase the transition between the two surfaces 3; 22 disturbing.
  • the color guide surface 22 first takes a straight course, which then merges into a concave curvature that ends in a color metering approach 5.
  • a vertical surface 24 of the ink metering element 6 forms with its ink guide surface 22 an angle ⁇ of approximately 90 ° and ends in a first support attachment 26.
  • the support attachment 26 stands approximately 1 mm beyond a curved back surface 27 of the ink metering element 6.
  • a neck 28 of the pivot arm 17 opens into this rear surface 27.
  • the rear surface 27 ends in one second support lug 29. While the first support lug 26 is supported on the base surface 10, the second support lug 29 is supported on the right guide surface 11 of the longitudinal pit 9.
  • the Stuetzansaetze 26, 29 preferably each extend over an entire length "c" of the Farbdosieriatas 6 and close to each other a a Winkeli of about 80 0th
  • 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 attachments 26, 29 can also have cutting edges, straight ends or also round ends.
  • An extension 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 bottom of the bore 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 bolt 33 which projects beyond the cross section of the swivel arm 17 and is connected to the swivel arm 17 in a form-fitting manner.
  • the two support attachments 26, 29 and thus the color 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 is drawn.
  • an axially parallel groove 39 extending over the entire length "c" of the ink metering element 6 is provided at a distance of approximately 1 mm from the ink guide surface 22. It serves to receive an elastic sealing cord 41, for. B. rectangular cross-section.
  • the sealing cord 41 extends in one piece over the entire length "b". It is selected in its dimensions so that in each operating position of the ink metering elements 6, the left guide surface 12 of the ink fountain base 2 is securely sealed against the vertical surface 24 of the ink metering element 6.
  • Paint metering element 6 and two side end plates 49, 50 delimited, sealed to the outside, extending over the entire length "b" lubricant chamber 43 is completely with a lubricant, for example Fat, filled in. This prevents printing ink or dirt from penetrating into the lubricant chamber 43 and impairing the smoothness of the ink metering elements 6.
  • 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 run in each case within the area boundary of the end faces 45, 46 and are approximately 10 mm long, 2 mm wide and 0.5 mm deep.
  • a lubricating nipple 20 is provided on the lateral end plate 49, via which grease can be pressed into the bore 44 of the ink metering elements 6.
