Definitions

  • the invention relates to a device for inking the type of a high speed printer-especially one operating according to the principle of flying print-that is one which has a continuously rotating type roller, which does not come to rest even during the printing operation.
  • an inking device which has an ink supply roller dispose-d in communication with the type roller over one or more intermediate rollers, and is characterized by adjustable gearing between the ink supply roller and its drive, through which gearing the ink supply roller, independently of the rate of rotation which it would develop with frictionless rolling of the rollers one upon another, receives such rotational speed as is necessary for an ink delivery in the desired quantity.
  • the ink supply roller preferably a felt roller
  • the soaking takes place only to such a degree that even if the ink supply roller were at a standstill, there could never occur any ink accumulation in the lower part of the roller or possibility of dripping.
  • the color delivery takes place to the desired extent only under the influence of centrifugal force occurring to the rotation of the roller. It is therefore possible, by regulating the rate of rotation of the ink supply roller, to determine the color delivery very precisely and to hold it approximately constant over a relatively long period of time by readjustment of the rate of revolution of the ink supply roller.
  • the rate of rotation of the ink supply roller will be lower than that which would result in the case of frictionless rolling of the rollers one upon another.
  • the gear utilized according to the invention offers also the advantages that in the more or less closed printing mechanism there cannot arise any excessively severe development of heat in consequence of the converted energy and thereby create a change in the viscosity of the printing ink. Further, the drive power is economized, inasmuch as no energy is deliberately converted into heat.
  • the uniform ink distribution required is achieved by the capillary forces in the interior of the felt roller. These forces also prevent the formation of an undesirably thick ink film on the 3,276,363- Patented Oct. 4, 1966 adjoining rollers, since excess ink is absorbed.
  • the relative velocity occurring as a rule at the roller surfaces of the ink supply roller and the adjoining roller may have a supplemental effect, but it is not a precondition for the development of a uniform ink film.
  • the type roller 1 is connected over the shaft 2, with drive means (not shown), by which it is maintained in steady, uniform rotation.
  • a first intermediate roller 3 for example, a rubber roller, and cooperable in rolling contact, with the intermediate roller 3, in the example represented, is a second intermediate roller 4, which, for example, is a steel roller.
  • the roller 4, in turn, is in frictional contact with the ink supply roller 5, for example, a felt roller.
  • the pairing of steel and felt is advantageous in achieving the lowest possible friction and wear.
  • a relative velocity on the roller surfaces between the type roller 1, the first intermediate roller 3 and the second intermediate roller 4 is undesirable. For this reason, under some circumstances there can exist between these rollers, in addition to the power connection, a positive connection, for example over gearing.
  • the ink supply roller 5 is supported on the two arms 6 and 7 to pendulate on the shaft 8, particularly in such a way that its pivotal arc strikes the intermediate roller 4 approximately perpendicularly.
  • Contact pressure of the roller 5 against the intermediate roller 4 is provided by the springs 9 and 10, which in each case are supported, on the one hand, on one of the two side plates 11 and 12 in which the rollers 1, 3, 4 and 5 as well as the shaft 8 are supported, and, on the other hand transmits, over the arms 6 and 7, a contact pressure force, to the ink supply roller 5.
  • a regulating transmission device or gearing 15 Connected to the ink supply roller 5 over a belt drive 13, :is a regulating transmission device or gearing 15 which, in the example represented, is operatively driven by the drive shaft 2 of the type roller 1 by a second belt drive 16.
  • the belt drive 13 provided with equally large belt wheels, permits the transmission of a torque, without influencing the pressure of the ink supply roller 5 against the second intermediate roller 4.
  • the shaft 8 forms a coaxial extension of the drive shaft 14, of the gearing 15 and carries the second belt wheel of the belt drive 13.
  • the regulating transmission device 15 is provided with adjusting means in the form of a rotatable knob 17, which makes it possible to change the transmission ratio of the regulating device 15, for example, from the exterior. Such an adjustment may, however, also take place automatically, especially in dependence on operating time.
  • the regulating transmission device 15 there is available, in particular, an infinitely variable drive transmission.
  • a diamond shaped surface profiling of the ink supply roller 5 can lead to further improvement with respect to the ink distribution.
  • a device comprising a belt drive between the ink supply roller and the transmission device provided with equally large belt pulleys, which is so arranged that the belt tension takes place in a direction perpendicularly to the contact pressure of the supply roller
