Definitions

  • the present invention relates to an inking device for rotary printing or duplicating machines, in which the inking device is provided for producing an inkfilm of constant thickness on an inking roller and on the printing form.
  • the applicator roller and the ink roller are rotated in the same direction, and the rotary speed of the ink roller is variable for adjusting a desired thickness of the ink film on the applicator roller.
  • Another possibility for adjusting the amount of ink is the use of an ink plate together with a duct roller.
  • the German AS 1,266,315 discloses a regulated motor, or regulated transmission for regulating the rotary speed of the ink roller.
  • the German AS l,l23,34l discloses manually operated threaded adjusting means for adjusting the ink blade, or the rollers.
  • the devices of the prior art have the disadvantage that they have to be operated not only before the start of a printing operation, but also during the printing operation in the event that the amount of supplied ink varies due to thermal expansion or contraction of the ink rollers caused by a temperature change. As a result, the ink supply has to be continuously observed and adjustments carried out.
  • Another object of the invention is to provide temperature responsive control means for automatically adjusting the gap between two ink rollers and the pressure between the same so that the ink film on the applicator roller remains constant when the ink rollers expand or contract due to temperature fluctuations.
  • Another object of the invention is to provide an inexpensive automatic inking device for producing an ink film of constant thickness on a transfer ink roller receiving a constant amount of ink from a metering ink roller.
  • stacks of bimetal strips abut the bearings of the metering ink roller for urging the same toward the transfer roller in accordance with the prevailing temperature.
  • an apparatus in accordance with the invention comprises a first ink roller mounted on supporting means for rotation; a second ink roller cooperating with the first roller for supplying ink thereto, means for supplying ink to the second ink roller; mounting means including means supporting the second ink roller for rotation, the mounting means supporting the second ink roller also for movement toward and away from the first ink roller; and temperature responsive control means, preferably including stacks of bimetal sprin gs, engaging the mounting means for moving the second ink roller toward and away from the first roller.
  • two stacks of bimetal springs are provided which have free movable ends carrying adjustable spindles engaging bearings in which the second ink roller is mounted.
  • FIG. 1 is fragmentary side view, partially in section, illustrating an embodiment of the invention.
  • FIG. 2 is a fragmentary plan view of the embodiment of FIG. l.
  • a first roller 7 is mounted in bearing brackets 8 and 9 on a pair of supporting walls 5 and 6, and transfers ink to a roller 37 which cooperates with the roller 39 so that the printing roller is inked.
  • a mounting means in the form of a pair of levers 2 is mounted on a shaft 4 for angular movement with a second roller 1 supported in bearings 32, 33 at the lower end of levers 2. Since the mounting means 2, 32, 33 of roller l are angularly movable about the axis of the shaft 4, roller l is movable with mounting means 2, 32, 33 toward and away from roller 7 forming therewith a gap or clearance in which a film of ink is located.
  • rollers 1 and 7 are rotated by meshing gears 39 and 40 of different diameters so that roller l rotates in the clockwise direction A, and roller 7 rotates in the counter clockwise direction B.
  • the gear transmission ratio is designed so that transfer ink roller 7 rotates at a lesser speed than metering ink roller l, for example at a rotary speed which is 3% less than the rotary speed of ink roller 1.
  • a driven shaft l0 is provided across an ink container 13 containing ink 14, and carries applicator varies 11 and l2 for transporting the ink 14 during each revolution of shaft 10 to the ink roller l.
  • a support 15 has ends secured to the supporting walls 5 and 6, and carries, by means of screws, two supporting blocks 16 and 17 in which stacks of bimetal springs 18 to 2l, and 22 to 2S are mounted, respectively.
  • the free ends of the bimetal springs 2l and 2S have threaded bores 26 and 27, while the other bimetal springs 19 to 24 are provided with aligned openings, registering with the threaded bores 26 and 27, so that threaded spindles 28 and 29, which are located in the threaded bores 26 and 27, can be mannually adjusted to press against the bearings 32 and 33 of the mounting means 4, 2, 32, 33 of ink roller l.
  • the spindles 28 and 29 can be adjusted and then secured in the adjusted position corresponding to a predetermined width of the gap between rollers l and 7.
  • this predetermined gap width is maintained automatically by the action ofthe bimetal springs so that always the correct amount of ink forming a film of predetermined desired thickness is produced on roller 37 and on the printing roller.
  • the accumulation 36 of ink between ink rollers l and 7 assures a uniform film on ink roller 7 which is transferred to the printing form, not shown.
  • Temperature responsive inking apparatus for a printing machine, comprising a first ink roller rotatable about a fixed axis; a second ink roller cooperating with said first ink roller for supplying ink thereto; means for supplying ink to said second ink roller; mounting means supporting said second ink roller for rotation Iabout its axis and for movement toward and away from said first ink roller; and temperature responsive control means engaging said mounting means for pressing said second ink roller towards said first ink roller with a force decreasing with increase ofthe temperature of the apparatus and vice versa so as to automatically maintain between said first and second ink rollers an inkcontaining gap of substantially constant width,
  • drive means including first and second meshing gears secured to said first and second ink rollers for rotation therewith so that said first and second ink rollers rotate in opposite directions; and wherein the diameter of said first gear is greater than the diameter of said second gear so that said first gear rotates slower than said second gear.
  • inking apparatus as claimed in claim l, comprising stationary supporting means supporting said mounting means for angular movement about an axis spaced from the axis of said second roller.
  • Temperature responsive inking apparatus for a printing machine, comprising a first ink roller rotatable about a fixed axis; a second ink roller cooperating with said first ink roller for supplying ink thereto; means for supplying ink to said second ink roller; mounting means supporting said second ink roller for rotation about its axis and for movement toward and away from said first ink roller; control means including bimetal means abutting said mounting means for pressing said second ink roller toward said first ink roller with a force decreasing with increase of the temperature of the apparatus and vice versa so as to maintain between said first and second ink rollers an ink-containing gap of substantially constant width; and drive means including first and second meshing gears secured to said first and second ink rollers for rotation therewith so that said first and second ink rollers rotate in opposite directions, the diameter of said first gear being greater than the diameter of said second gear so that said first gear rotates slower than said second gear.
  • Temperature responsive inking apparatus for a printing machine, comprising a first ink roller rotatable about a fixed axis; a second ink roller cooperating with said first ink roller for supplying ink thereto; means for supplying ink to said second ink roller; mounting means supporting said second ink roller for rotation about its axis and for movement toward and away from said first ink roller; and control means engaging said mounting means for pressing said second ink roller towards said first ink roller with a force decreasing with increase of the temperature of the apparatus and vice versa, so as to maintain between said first and second ink rollers an inkcontaining gap of substantially constant width, said control means including at least one stack of bimetal springs ⁇ and a threaded spindle adjustably mounted on said stack and having one end abutting said mounting means.
