Definitions

  • the invention relates to a method, a device and a squeegee for emptying ink fountains according to the preamble of claims 1, 2 and 6.
  • an ink fountain for a rotary printing press consisting of an upper part and a lower part and a color knife that can be placed on the ductor, is known in such a way that an upper part designed as an ink container is removably arranged on the ink knife-bearing lower part.
  • the disadvantage of this removable ink container is that when using different printing inks too a number of paint containers must be created in order to use them quickly when changing colors.
  • the invention has for its object to provide a method, a device and a squeegee for emptying ink fountains for rotary printing presses, with which the residual ink can be removed quickly and easily from the ink fountain during color changes or cleaning work.
  • FIG. 1 parts of an inking unit of a rotary printing press for web offset printing are shown.
  • An ink fountain roller 2 and a film roller 3 are mounted in a machine frame 1.
  • a paint application device designated by 4 can be placed on the ink fountain roller 2.
  • the ink application device 4 consists of an ink fountain 6 and an associated adjusting device 7 for known ink knives 8.
  • the ink fountains 6 can be used in connection with the adjusting device 7 in full, half or quarter-wide design according to the printing requirements.
  • the paint application device 4 is provided at its base 9 with trunnions 11, which are in fixed bearings 12 on one between the side parts of the Machine frame 1 extending cross member 13 are mounted.
  • the ink application device 4 is pivoted about the bearing pins 11 into a rest position, not shown, which is remote from the ink duct.
  • the adjusting device 7 carries the ink fountain 6, which each has two side parts 16, which have approximately the shape of triangles standing on the top and are adapted to the diameter of the ink duct 2 on their ducor side.
  • a bottom surface 17 of the ink fountain 6 which runs obliquely downward in the direction of the ink fountain roller 2 is formed both by the top 18 of the housing of the adjusting device 7 and by holders 19 of the ink knife 8.
  • the adjusting device 7 has eccentrics 21 which are connected via transmission elements 22, for. B. screws, with adjusting levers 23 for color knife 8 in connection.
  • the adjusting lever 23 are mounted on an axle 24 fixed to the housing.
  • the collecting container 27 is either full, half or quarter width depending on the width of the ink fountain 6.
  • On the end faces 31; 32 of the collecting container 27 are carrying elements, for. B. Handles 41; 42 arranged.
  • a vertical partition 43 can be arranged, behind which a storage container 44 for equipment is formed.
  • the collecting container 27 can also consist of sheet metal. According to Fig.
  • a doctor blade designated overall by 46 which consists of a sheet metal plate 47 with a width b which corresponds to the clear width of the ink fountain 6 delimited by the side parts 16 and a height h which corresponds approximately to the diameter d of the ink ductor 2 .
  • This squeegee 46 has at one end parallel to the width b a right-angled bend 48 with handles, z. B. handles 49; 51.
  • the squeegee 46 has squeegee strips 52 with a working edge 53, which also run parallel to the width b, at its end opposite the fold 48.
  • the doctor strip 52 is by means of a strip-shaped holding plate 54 with the help an insert 56 clamped by rivets 57 or spot welds between the sheet metal plate 47 and the holding plate 54.
  • the doctor strip 52 protrudes by the amount a beyond the sheet metal plate 47 or the holding plate 54.
  • the amount a can be between 10 and 80 mm.
  • the material of the doctor strip can be made of brass, or plastic, e.g. B. polyoxymethylene (POM) or rubber.
  • the procedure for emptying ink fountains is as follows. To empty the ink fountain 6, the squeegee 46, whose width b approximately corresponds to the width of the ink fountain 6, is inserted into the ink fountain 6, so that the working edge 53 of the doctor blade strip 52 grazes along the outer surface of the ink ductor 2 until the working edge 53 touches the bottom surface 18 has reached in the vicinity of an axis-parallel line 58, which represents the line of contact of the color knives 8 arranged next to one another with the jacket of the color ductor 2.
  • the doctor blade 46 After reaching or nearing line 58, the doctor blade 46 is moved along the bottom surface 17 of the ink fountain 6 in the direction of the edge 26 of the collecting container 27, the residual ink 28 being collected and brought into the interior 30 of the collecting container 27 for residual ink 28 . If necessary, this process must be repeated several times.
  • the residual color 28 can of Squeegees 46 can be wiped off at the upper edge 59 of the partition 43, the upper edge 59 of the partition 43 also being able to be bent in the direction of the ink duct 2.
  • the doctor blade 46 can then be deposited in the storage container 44.
  • the collecting container 27 can be easily removed by lifting it upwards in the vertical direction from the ink application device 4, so that the ink application device 4 can subsequently be pivoted away from the ink duct 2 by means of the working cylinders 14 for the purpose of subsequent cleaning work.
  • the material of the doctor blade strip 52 is in any case softer than the material of the ink duct 2.
  • the doctor blade 46 can also be made in one piece and consist of one material.
  • the width b of the doctor blade 46 can correspond to half and the entire inside width of the respective ink fountain width.
  • the height h of the doctor blade 46 does not have to correspond exactly to the diameter d of the ink duct 2, but can also deviate upwards or downwards.
