Definitions

  • the invention relates to an inking unit for rotary printing presses according to the Preamble of claim 1.
  • an inking unit is rotatable with one in the frame stored roller in the form of a color ductor and one of these swivel-mounted paint container in the form of a paint box known.
  • the invention has for its object an inking unit for rotary printing presses according to the preamble of claim 1 to create the both a largely color residue-avoiding, user-friendly Color emptying of the paint container as well as a thorough cleaning good accessibility of the latter and the roller.
  • the combination of the swiveling movements of the paint container and the die Roller bearing bracket allows favorable conditions for both the Color emptying of the paint container as well as the cleaning of the latter as well as the roller, including washing.
  • the roller and the ink tank together into a roller that drains off the ink releasing position can be pivoted so that the following Swiveling the ink container away from the roller prevents ink from escaping becomes.
  • the color emptying of a paint container or the Removal of an additional stake favors, and for a very good one Accessibility when washing is from the already swiveled roller the paint container can also be swung out.
  • the solution according to the invention also allows an interruption of the Contact of the still operational roller and ink duct Establishment of a downstream transfer roller. It is the roller can be driven as required in any swivel position.
  • the one working with a paint container in the form of a chambered doctor blade Roller can be equipped with recesses for ink absorption both as anilox roller for a short inking unit as well as a uniform structured Form roller for example for fund printing or as uneven structured form roller can be designed for general printing.
  • Fig. 1 shows in connection with Fig. 6 a rotatable in a holder 1 stored, drivable roller I in the form of an ink fountain roller 2, to the one Paint container II is pivoted in the form of a paint box 3.
  • Paint container II is pivoted in the form of a paint box 3.
  • the one lying on the inside of the frame Axis 8 has an axially matching bore 10 in gesture 9 aligned fitting bore 11, in which in the fitting bore 10 in gesture 9 engaging dowel pin 12 sits.
  • the axis 8 is in each case on the end face screwed to the frame 9 (Fig. 6).
  • a motor 13 is located on the side of the lever 6, coaxial with the ink fountain roller 2 flanged to the ink fountain roller 2 via a fixed coupling 14 connected is.
  • the gesture 9 is for the motor 13 with the pivoting the bracket 1 enabling recess 15 equipped.
  • the ink fountain 3 is attached to the ink fountain roller 2 swiveled position lockable against the bracket 1.
  • To engages in the housing of the ink fountain axially displaceable locking bolt 16 into a bore 17 of the holder 1 that is aligned with this a.
  • the holder 1 In the operating position, the holder 1 lies against an adjustable stop 18 the contact of the ink fountain roller 2 to a downstream transfer roller 19 limiting.
  • bracket 1 and the locked paint box 3 together by means of a pressure medium operated, acting on the bracket 1 and on Gestured articulated cylinder 20 is pivoted, this is done separately for unlocked ink fountain 3 by hand with the help one attached to this handle 21, the pivoting movement of the Color box 3 favorably by a stop, not shown or a lock relative to the bracket can be limited.
  • the color box 3 with a exchangeable ink fountain insert 22.
  • Fig. 6 are four ink boxes 3, each of a quarter-wide design arranged separately next to each other. These are alternative interchangeable with a full or one or two half-width ink boxes.
  • the storage 24 for the Ink fountain 3 in several parts, which can be screwed together radially on axis 8 Bearing shells 25; 26 are executed. This is also a quick one Exchange of different width ink boxes possible.
  • FIG. 3 shows, compared to FIG. 2, one after the locking bolt 16 has been released from the bore 17 of the holder 1 from the ink fountain roller 3 additionally pivoted paint box 3, which the entire facility for the Cleaning is optimally accessible.
  • Fig. 4 shows the holder 1 with the ink fountain roller 2 in contact with Transfer roller 19 analog to FIG. 1 and the ink fountain 3 analog to FIG. 3 in which a cleaning, pivoted away from the ink fountain roller 3 Position.
  • Fig. 5 shows a parked by the transfer roller 19 and thus in Contact of the ink fountain roller 2 to the transfer roller 19 interrupted, otherwise, however, operational facility.
  • FIGS. 7 and 8 show a modified version with respect to FIGS. 1 and 6 Device that the bracket 1 'by means of one of the two levers 6', 7 ' connecting, mounted on the axis 8, the ink fountain 3 'pivotable bearing tube 29 is effectively stiffened as a crossbar.
  • the locking bolt 16 'of the ink fountain 3' engages in this version in the tube 29 arranged bore 17 '.
  • the ink fountain 3 'in FIG. 7 is on the one hand on one attached to the tube 29, the storage 24 'of the ink fountain 3' in one a recess 30 permitting a pivoting movement radially penetrating Lever 31 and on the other hand on the ink fountain 3 'articulated cylinder 32 swiveling.
  • FIG. 9 shows an axis parallel to the mounting of the holder 1 ′′ offset in this stored color box 3 ''.
  • the tube 29 'and on the ink fountain 3 ′′ mutually overlapping bearing levers 33, 34 attached, each parallel to the axis 8 'of the bracket 1' ' Bearing bolts 35 are penetrated.
  • FIG. 10 shows a drive variant for an axle 36 that is fixed to the frame and equipped with a roller jacket 37 rotatably mounted on the latter Ink fountain roller 2 ', such as one laterally attached to the lever 6' ' Motor 38 by means of a worm 39 on the roller jacket 37 coaxially attached worm wheel 40 drives.
  • an ink fountain roller 2 '' of the same design as in Fig. 10 drives a disc rotor motor 41, whose rotor 42 coaxially on the roll shell 37 'is fixed and stator 43 is seated on the axis 36'.
  • the drive for the ink fountain roller 2 is not shown; 2 '; 2 '' can also be designed such that on the axis 8 or the tube 29; 29 'coaxial to the pivot axis of the holder 1; 1'; 1 '' an arbitrarily drivable drive wheel is rotatably mounted, which via a drive with the ink fountain roller 2; 2 '; 2 '' communicates.
