Definitions

  • the invention relates to a device for supplying printing ink to an inking unit of a rotary printing press according to the preamble of claims 1 and 6.
  • DE-PS 870 816 shows a manual ink press for squeezing printing ink from a tube by means of a piston, the piston being actuated by means of a threaded spindle.
  • the invention has for its object to provide a device for feeding printing ink.
  • a screw jack motor which is simple in construction and with which metering of printing ink takes place precisely.
  • position control of an associated threaded spindle of the screw jack motor is possible in a simple manner by means of a sensor, for example a rotary pulse generator attached to the electric motor.
  • a sensor for example a rotary pulse generator attached to the electric motor.
  • Anilox roller as well as for the device for supplying printing ink achieved by a pivotable crossbar to which the device for supplying printing ink is attached.
  • the device according to the invention is shown in the drawing 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.
  • the ink fountain 4 is a feed device 7 for Assigned ink supply.
  • 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 crossbeam 8 is arranged axially parallel to the anilox roller 2 between side frames 18, 19 of the rotary printing press.
  • the crossmember 8 is pivotally connected to a side frame 18 at least in one plane by means of a swivel joint 21.
  • the crossmember 8 is arranged so that it can be swung out horizontally from the side frames 18, 19.
  • the traverse 8 can also, depending on the arrangement of the ink fountain 4 in different directions, for. B. vertically pivoted.
  • the crossmember 8 is U-shaped in cross section. At a first end of the crossmember 8, the spindle lifting motor 9 is fastened on the inside, so that its threaded spindle 22 extends parallel to the crossmember 8.
  • a piston 23 is arranged at a first end of the threaded spindle 22.
  • the diameter of this piston 23 is adapted to an inner diameter of the sleeve 12 of the ink cartridge 11 and works together with the disk 17 of the ink cartridge 11.
  • the piston 23 presses the printing ink in the printing ink cartridge 11 directly or with the interposition of a film.
  • the piston 23 cooperates sealingly with an inside of the sleeve 12 of the ink cartridge 11.
  • the threaded spindle 22 is moved in its longitudinal direction by a nut, not shown.
  • the nut which can be rotated by means of an electric motor 24, is otherwise fixed in position with respect to the crossmember 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 screw jack motor 9 works directly or indirectly with a sensor for detecting a position of the threaded spindle 22.
  • the electric motor 24 is provided, for example, with a rotary pulse generator.
  • the electric motor 24 can advantageously be designed as a stepper motor.
  • the piston 23 of the screw jack motor 9 is followed by a receptacle for the ink cartridge 11, viewed in the axial direction.
  • this receptacle can only be designed as a stop or can be provided with a threaded bore into which the fastening thread of the printing ink cartridge can be screwed.
  • an outlet 26 attached to the crossmember 8 is provided.
  • This tubular outlet 26 extends perpendicular to the cross member 8 in the direction of the ink fountain 4 and is provided with an opening 27 at its end facing the ink fountain 4. At its second end, the outlet 26 is provided in the axial direction of the anilox roller 2 with a threaded bore 28 for receiving the ink cartridge 11.
  • the electric motor 24 of the screw jack motor 9 is actuated.
  • the piston 23 is then moved in the direction of the ink cartridge 11 by means of the threaded spindle 22.
  • the piston 23 comes into contact with the disk 17 and presses against it.
  • the disk 17 moved by the piston 23 now conveys printing ink from the printing ink cartridge 11 via the outlet 26 into the ink fountain 4.
  • the screw jack 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.
