Definitions

  • the present invention relates to a rotary pad printing machine for printing objects with a substantially cylindrical outer side.
  • Pad printing machines are known in the prior art in numerous designs and are used for printing differently shaped objects. For this purpose, a print image is taken from a cliché by means of a printing pad and then transferred to an object to be printed. By forming the printing pad from an elastic material, it is also possible to print on comparatively uneven surfaces.
  • Rotary pad printing machines are particularly suitable for printing objects with a cylindrical outer side. These allow a very fast and efficient circumferential printing of the outside of the object to be printed.
  • a round tampon is used with a cylindrical outer surface, which is unrolled for print image recording on a likewise cylindrical plate roller and at the same time for print image transfer on the outside of the object to be printed.
  • rotary pad printing machines can be used to print a large number of objects in a relatively short time.
  • Such a rotary pad printing machine is for example from the EP 1 447 219 known.
  • rotary ink pad printing machines In order to apply the ink to the plate roller during the printing operation, rotary ink pad printing machines generally provide an inking roller which is partially immersed in the ink received in a paint pan. In addition, by the inking roller rests against the cliché roller and rotates with the printing operation with this, the ink is applied by the inking roller to the cliché roller. By means of a doctor blade excess paint is stripped from the plate roller, so that remains as uniform as possible color application on the plate roller. See the FIG. 1 U.S. Patent No. 5,309,830, showing a rotary pad printing machine having such a prior art open color dispensing system.
  • the DE 195 36 765 A1 and the DE 101 15 857 A1 each show rotary pad printing machines with largely closed inking systems.
  • the ink tray is designed in each case such that it encloses a part of the plate roller.
  • the ink pans of these inking systems are relatively poorly sealed to the outside.
  • these Farbgebersysteme claim relatively much space.
  • the doctor blade with each the region of the peripheral surface of the plate roller include an acute angle which moves towards the doctor blade during normal printing operation.
  • the doctor blades do not depend on the relief-like elevations or depressions formed on the peripheral surface of the plate roller, but are pressed radially outward by them and then spring back into the starting position.
  • An adequate seal between the ink fountain and the peripheral surface of the plate roller is guaranteed at any time. Due to the good sealing, the ink can be applied to the peripheral surface of the plate roller with a higher pressure from the ink fountain, which means that the contact surface, which is necessary for contacting the plate roller with ink, can be reduced, so that the color generator takes up less space overall ,
  • the rotary pad printing machine may have one or more printing modules, each of which has a round tampon, a cliché roller, and a colorant.
  • a printing module each of which has a round tampon, a cliché roller, and a colorant.
  • the cliché roller can be made of a metal, in particular steel, but also of a ceramic material or a plastic.
  • the ink fountain housing usually has an outlet opening to allow the ink to pass from the interior of the ink fountain on the peripheral surface of the plate roller.
  • the interior of the ink fountain with the exception of this outlet opening and any existing Farbzu wool- and / or Farbablassstutzens completely completed to the outside.
  • the outlet opening is advantageously bounded laterally by a contour which has a curvature which substantially corresponds to the curvature of the peripheral surface of the plate roller.
  • the ink fountain pen thus has in the region of the outlet advantageously a to the Peripheral surface of the plate roller adapted outer surface.
  • the ink fountain housing can be arranged in accordance with the intended printing operation of the rotary pad printing machine with respect to the direction of gravity above the cliché roller, so that the pressure contained in the interior pressure ink rests on the peripheral surface of the plate roller.
  • Such an arrangement has the advantage that the ink received in the ink fountain housing is always in contact with the peripheral surface of the plate roller during printing operation, even if only a small amount of printing ink is present in the interior.
  • the color sensor housing could of course also be arranged below the cliché roller.
  • the ink fountain box would then be designed and arranged so that the plate roller would dive along a certain peripheral area in the ink. Regardless of the arrangement of the ink fountain pen relative to the plate roller, could optionally be provided in the interior of the ink fountain housing a piston to apply the ink with a certain pressure on the plate roller
  • the two doctor blades with respect to the peripheral surface of the plate roller, less than 60 °, in particular less than 40 °, spaced from each other.
  • the two doctor blades thus preferably delimit a segment of the plate roller of less than 60 °, more preferably less than 40 °.
  • the doctor blades may be made of ceramic, a metal, in particular steel, or of a plastic material.
  • the round tampon has a first axis of rotation and the cliché roller has a second axis of rotation, which usually run parallel to one another.
  • a particularly space-saving arrangement results when the ink fountain housing is arranged in the region of an imaginary straight line extending in each case perpendicularly through this first and this second rotation axis.
  • the round tampon, the cliché roller and the Farbgebergeophuse are then arranged so essentially on a line.
  • the individual printing modules of the rotary pad printing machine can then be arranged very close to each other and thus save space.
  • a Rotary indexing table in combination with the rotary pad printing machine can then be chosen thanks to the space-saving arrangement of the printing modules, a relatively inexpensive rotary indexing table with a small diameter. The total space required by the rotary pad printing machine is thereby reduced considerably.
  • the two doctor blades are each attached to the color coder housing.
  • the rotary pad printing machine also has an oscillation drive unit for oscillating the ink fountain housing with the doctor blades attached thereto during the printing operation relative to the plate roller substantially parallel to the rotation axis of the plate roller.
  • the oscillation movement which can be only a few millimeters, serves to achieve a uniform wear of the doctor blades.
  • At least one, even more advantageously both doctor blades are attachable to the ink fountain by means of a mounting plate so that they are clamped between the mounting plate and the ink fountain. By clamping the forces acting on the doctor blade forces can be optimally absorbed.
  • the doctor blade which is arranged in front relative to the direction of rotation of the plate roller provided for the printing operation, is inclined more toward the peripheral surface of the plate roller than the doctor blade arranged at the rear.
  • the spring effect of the doctor blade is thus optimally adapted to the pressure conditions caused in the region of the outlet opening by the rotation of the plate roller.
  • the Farbgebergeophen has a Farbzu Chinastutzen and / or a Farbauslassstutzen for supplying or discharging ink into or out of the interior of the Farbgebergeophuses on.
  • the interior and thus the Farbgebergeophuse can thereby be made smaller, since the colorant can constantly be supplied with new ink.
  • the rotary pad printing machine also has a paint pump and a control unit, wherein the paint pump can be connected in a color cycle via corresponding lines to the ink feed nozzle and the paint outlet.
  • the control unit is preferably a viscometer for controlling the viscosity of the ink circulating in the ink circulation.
  • a diluent feed unit for supplying diluent to the circulating ink as needed.
  • Other sensors for monitoring the ink properties may be provided in this cycle. It would also be conceivable to arrange a paint pump, a viscometer and / or a Verizernerzu Profieri within the Farbgebergeophuses to control the ink directly in the interior of the Farbgebergeophuses and if necessary to provide with additional thinner.
  • a holder is preferably provided, which is connectable by means of a dovetail connection with the Farbgebergeophuse.
  • a dovetail connection allows a particularly simple removal and attachment of the Farbgebergeophuses for example for cleaning purposes.
  • the rotary pad printing machine also has an Anpresstician, which serves for pressing the Farbgebergephaseuses and in particular the doctor blade to the peripheral surface of the plate roller.
  • the pressing unit is preferably designed to machine the contact pressure of the ink fountain housing to the plate roller. It is preferably a pneumatic pressing unit. It could also be a hydraulically or electrically driven pressing unit.
  • the rotary pad printing machine also preferably has a relative to the round tampon and in particular in a direction perpendicular to the rotational axis of the rotary tampon direction movable cliché carriage on which the cliché roller and the ink fountain pen are mounted.
  • the cliché slide is electrically displaceable by means of a servo motor.
