Definitions

  • the invention relates to a rotary pad printing machine with a gravure roll with vertical axis of rotation, with one or more pad rollers and a Farbgebersystem for coloring the gravure roll.
  • Rotary pad printing machines with vertically standing gravure rolls are known. These rollers have the difficulty of applying the ink evenly to the gravure roll so that the engravings are completely filled with ink.
  • the US-A-5, 435, 873 shows a printing system with rollers with horizontal axes.
  • the printing ink with which the gravure roll is inked conveyed by means of an Archimedian screw from the paint drip tray and passed over the guide on the peripheral surface of the gravure roll and thus colored the engravings. It is advantageous that this system works according to the invention without contact, in contrast to systems that use inking rollers.
  • this system is independent of the height of the gravure roll, since by means of the Archimedian screw in the area in question, the ink can be promoted to any height. By adjusting the dosing gap, the system can be adapted to the properties of the paint.
  • the Archimedean screw, the drip tray and the guide are parts of the Farbgebersystems. This has the significant advantage that the inking system is handled separately, without this, the gravure roll or the pad roller are affected. It must therefore, especially when changing the ink, no new position settings neither in the gravure roll at the pad roller can be made. Also, the maintenance and repair can be carried out easier because the entire color donor system can be replaced.
  • the guide is advantageously designed such that it comprises the outlet opening of the Archimedean screw and is guided to the peripheral surface of the gravure roll. In this way, the ink can be optimally guided to their destination.
  • the Archimedean screw is arranged vertically.
  • the Archimedean screw is slightly inclined, in particular inclined in the direction of the gravure roll.
  • a collecting device for printing ink running from the gravure roll is provided below the gravure roll.
  • This collecting device is designed in the manner of a Sammelbeckens and has a sloping bottom, which in the Ink collecting tray of Farbgebersystems opens. In this way, the running of the gravure roller ink is returned to the Farbgebersystem.
  • a particularly preferred embodiment provides that the Archimedean screw is driven by a variable speed drive. In this way, the flow rate can be optimally adapted to the needs or to the type of ink.
  • the drive has a sensor for determining the power consumption.
  • the power of the drive can be adapted to changing environmental conditions.
  • a monitoring device is provided which has the corresponding control circuits. For example, e.g. Also provided is a thinner feeder if the color thickness exceeds a threshold.
  • the guide is adaptable to the height of the gravure roll.
  • the same inking system can be used with differently high gravure rolls, e.g. Heights of 50 mm, 100 mm, etc. may be used.
  • the system is designed to be essentially closed.
  • the pad roller is coupled with a residual ink pickup.
  • This residual color pickup e.g. is designed as a revolving, politicianpressende on the tampon roller carries at its periphery a Farbabholfolie, which is replaced if necessary.
  • a film strip can be pressed onto the peripheral roller of the pad roller and thereby the residual color are lifted.
  • FIG. 1 shows a side view of a rotary pad printing machine designated overall by 10, where 12 denotes a pad roller which is fastened to a vertical axis of rotation 14.
  • the axis of rotation 14 is driven by a gear 16, which meshes with a gear 18 which is fixed to a shaft 20.
  • the axis of rotation 14 is mounted in bearings 22 highly accurate.
  • a gravure roller 26 is rotatably mounted, on which the pad roller 12 rolls. Also, the shaft 20 is mounted in corresponding bearings 28 highly accurate.
  • a generally designated 30 Farbgebersystem which has a drip tray 32, in which ink is collected.
  • An Archimedean screw 34 which is aligned vertically and is coupled to a drive 36 on its upper side, dives into this ink collecting tray 32.
  • the discharge opening 38 of the Archimedean screw 34 is also located at the top and opens into a guide 40 which is directed towards the peripheral surface 42 of the gravure roll 32.
  • the dispensing opening 44 of the guide 40 is in the immediate vicinity of the gravure roller 26 and is only spaced by a metering gap 46 of this.
  • the dispensing opening 44 is also adapted to the curvature of the peripheral surface 42 so that the metering gap 46 does not change.
  • the height of the dispenser opening 44 substantially corresponds to the height of the gravure roller 26, so that it is colored over its entire circumference.
  • the guide device 40 is executed between the dispensing opening 44 and the discharge opening 38 of the Archimedean screw 34 substantially as a channel 48 and inclined steadily downwards. When the Archimedean screw 34, this channel 48 thus runs empty.
  • the collecting device 50 In which ink discharged from the peripheral surface 42 is collected and conducted in the direction of the ink tray 32.
  • the collecting device 50 has a sloping bottom 52, which ends above a collecting mouth 54 of the ink tray 32 in a pour-like outlet 56.
  • the drive 36 is provided with a sensor (not shown), which determines the power consumption of the drive 36 and supplies the information to a monitoring device. Exceeds the power of the drive 36 due to thickened ink a preset value, the ink is supplied thinner, so that the Viscosity is lowered again. This can be done automatically via a control loop.
  • a level sensor 32 may be provided in the drip pan, which reports a too low level.
  • FIG. 2 shows a plan view of the rotary pad printing machine 10 and it is clearly visible the guide device 40, which is brought directly into the region of the circumferential surface 42 of the gravure roller 26. Furthermore, gears 58 and 60 are still shown, which drive the two gears 16 and 18.
  • adjusting devices 62, 64 and 66 By means of adjusting devices 62, 64 and 66, the position of the gravure roll 26, the position of the tampon roll 12, the contact pressure of the tampon roll 12 on the gravure roll 26, the contact pressure of the doctor blade on the peripheral surface 42 of the gravure roll 26 and can the heights of the rollers 12th and 26 are set.
  • the inking system 30 is designed as a component which can be handled separately, which is used e.g. when changing the ink only needs to be replaced.
