Definitions

  • the invention relates to a device for feeding Ink to an inking unit Rotary printing machine according to the preamble of Claim 1.
  • DE-PS 870 816 shows a hand paint press for Squeezing ink from a tube using a Piston, the piston by means of a threaded spindle is operated.
  • EP 07 16 923 A2 discloses a device for Supply of an inking unit with color, whereby one Cartridge is attached to a traverse.
  • US 51 50 651 A is a device for Feeding ink known in parallel to one Longitudinal axis of an ink roller is pivotable.
  • the invention has for its object a To provide a device for feeding ink.
  • one of a Ink cartridge amount of ink to be conveyed be dosed exactly.
  • a Used screw jack motor that is simple to build and with dosing of printing ink takes place precisely. It is a position control of an associated threaded spindle Screw jack motor using a sensor, for example a rotary encoder attached to the electric motor, in easily possible.
  • the device according to the invention is in the drawing shown and is described in more detail below.
  • a metering device 1 for supplying printing ink to an inking unit of a rotary printing press has, for example, an inking roller, e.g. B. an anilox roller 2 and a provided with a doctor device 3 ink fountain 4.
  • This ink fountain 4 is open on its upper side or at least provided with an opening 6 for supplying printing ink.
  • a supply device 7 for supplying printing ink is assigned to the ink fountain 4.
  • This feed device 7 essentially consists of a crossbeam 8, a screw gear designed as a screw jack motor 9 and a receptacle for an ink cartridge 11.
  • This ink cartridge 11 has as a body a circular cylindrical sleeve 12 which is closed at the end with a cover 13. This cover 13 is provided with an outlet opening 14.
  • This outlet opening 14 can, for example, be integrated in a central fastening thread 16, which is arranged centrally in the end cover 13.
  • the ink cartridge On its second end face, the ink cartridge is covered with a disk 17 acting as a piston. This disc 17 is displaceable within the sleeve 12.
  • Sleeve 12, cover 13 and disc 17 form a storage for printing ink.
  • the traverse 8 is axially parallel to the anilox roller 2 between side frames 18, 19 of the Rotary printing press arranged.
  • a Swivel 21 is the crossmember 8 at least in one Level pivotally connected to a side frame 18.
  • the traverse is 8 horizontally from the side frames 18, 19 arranged pivotable.
  • the traverse 8 can also depending on the arrangement of the ink fountain 4 in different directions, e.g. B. vertically pivotable be arranged.
  • the crossmember 8 is U-shaped in cross section. At a first end of the traverse 8 is the inside Spindelhubmotor 9 attached, so that it Threaded spindle 22 extends parallel to the crossmember 8.
  • a Piston 23 arranged at a first end of the threaded spindle 22 .
  • This piston 23 is with his Diameter to an inner diameter of the sleeve 12 Ink cartridge 11 adapted and works with the Disk 17 of the ink cartridge 11 together. It is but also possible to omit the disc 17, so that the piston 23 directly or with interposition a film on the printing ink in the Ink cartridge 11 presses.
  • the piston 23 acts for this purpose sealing with an inside of the sleeve 12 Ink cartridge 11 together.
  • the threaded spindle 22 is from a nut not shown in her - Moved in the longitudinal direction. This is done using a Electric motor 24 rotatable nut otherwise stationary stored with respect to the traverse 8. Nut, threaded spindle 22 and electric motor 24 essentially form the Screw jack motor 9.
  • the electric motor 24 or the threaded spindle 22 of the Spindle lifting motor 9 works with a sensor Detection of a position of the threaded spindle 22 directly or indirectly together.
  • a sensor Detection of a position of the threaded spindle 22 directly or indirectly together for this is in the present Embodiment of the electric motor 24 for example provided with an encoder.
  • the electric motor 24 can advantageously be designed as a stepper motor his.
  • the piston 23 of the screw jack motor 9 closes in seen in the axial direction a recording for the Ink cartridge 11 on.
  • This recording can be done in simplest case only be designed as a stop or be provided with a threaded hole in which the Fastening thread of the ink cartridge can be screwed in.
  • an is on the traverse 8 attached outlet 26 is provided.
  • This tubular outlet 26 extends perpendicular to Traverse 8 runs in the direction of ink fountain 4 and is at its end facing the ink fountain 4 with a Provide opening 27.
  • the Spout 26 in the axial direction of the anilox roller 2 with a threaded bore 28 for receiving the Ink cartridge 11 provided.
  • the operation of the invention Feed device is as follows:
  • the spindle lifting motor 9 can be actuated manually or in a predetermined manner by using a position of the threaded spindle 22 for metering a quantity of printing ink. Regulation of the screw jack motor 9 by means of a fill level sensor in the ink fountain 4 is also possible. This screw jack motor is particularly suitable for automating the supply of printing ink. In addition to the control of the screw jack motor via a fill level sensor already mentioned, it is also possible to automatically control the screw jack motor as a function of an ink quantity per unit of time adapted to the ink consumption under certain production conditions.
