Definitions

  • the modern rotary press particularly those used for high-speed newspaper printing, must be readily adapted for color printing as well as basic black printing.
  • the ink supplying arrangement must be capable of delivering controlled quantities of ink for high speed printing in a continuous, uninterrupted flow.
  • An ink fountain-fountain roller arrangement has long been a widely used method of supplying ink to a rotary press. Basically, this approach includes a fountain roller which rotates in a body of ink. The roller surface carries a coating of ink, whose thickness is controlled by an adjacent knife blade, to the inking rollers of the press.
  • the inking arrangement may be divided into sections which supply ink to adjacent portions of the plate cylinder.
  • a further object is to provide a fountain arrangement of the above character having separable, easily handled color ink pans which combine screen, pump, level control and ink container, all in one assembly which can be quickly and easily installed in the press to convert from black to color printing.
  • Another object is to provide a fountain inking arrangement as described above which permits colored ink to be substituted in any selected page section without disturbing the black ink supply mechanism for the section or the other portions of the press. Moreover, an object is to provide a fountain arrangement of this kind which allows conversion to colored ink supply without draining and cleaning the basic black ink supplying structure.
  • FIGURE 1 is a somewhat diagrammatic side elevation of a press including an inking arrangement embodying the invention
  • FIG. 2 is an enlarged fragmentary perspective, with portions broken away, of the inking arrangement shown in FIG. 1 as adapted for basic blank ink printing;
  • FIG. 3 is similar to FIG. 2 but shows the arrangement adapted for color ink supply
  • FIG. 4 is an enlarged transverse section of a portion of the structure shown in FIG. 3;
  • FIG. 5 is a fragmentary elevation, with portions broken away, as seen from the right-hand side of FIG. 4;
  • FIG. 6 is a fragmentary plan of the structure shown in FIG. 5.
  • FIG. 1 a rotary newspaper type press 10 having an inking arrangement 15 embodying the invention.
  • the press includes support or frame structure generally indicated at- 16 which supports an impression cylinder 17 and a plate cylinder 18.
  • a plurality of inking rollers 19 are journalled in the frame for carrying ink from the inking arrangement 15 to the plate cylinder 18.
  • similar structure is mounted in the other half of the press.
  • the inking arrangement 15 includes a fountain roller 21 and a doctor blade or knife 22 which regulates the thickness of the ink film on the fountain roller that is transferred to the inking rollers 19.
  • the press also includes a doctor knife controlling mechanism 23.
  • overflow fountains 25 are provided immediately adjacent the fountain roller 21, and the fountains are supplied with circulating ink from either a trough 26 underlying and in spaced relation to the roller 21 or a pan 27 removably mounted between the trough and the fountain roller.
  • the overflow fountains 25 are defined by plates 28 removably mounted in the press frame 16 below the doctor knife 22 and between upstanding page section walls 29.
  • the space between adjacent ones of the walls 29 corre sponds to the length of one printed page so that inking of each page can be independently controlled.
  • the plates 28 carry metal blades 31 in scraping contact with the fountain roller 21 and are formed, at their upper edges, with overflow outlets 32.
  • the primary supply of ink is maintained in the trough 26 which constitutes a portion of the press frame 16 underlying the press room floor 35.
  • the trough 26 extends the full length of the fountain roller and is supplied with ink through a conduit 36 that ends in a fluid level sensing device such as a float valve 37.
  • a pump 38 is mounted on the press below the press room floor 35 and draws ink fromthe through 26 through a conduit 39.
  • the pump 38 discharges ink through a conduit 40 to a supply conduit 41 running the width of the press.
  • a connection such as a flexible hose 42 extends from the supply conduit 41 to each fountain and is releasably connected to the adjacent fountain 25 through a fitting attached to the plate 28.
  • a coarse screen 43 overlies the entire trough 26.
  • a plurality of sliding mist guards 44 enclose the inking arrangement 15 while providing ready access thereto.
  • the desired level of ink in the trough 26 is maintained by the float valve 37.
  • the pump 38 supplies, through the conduits 40, 41 and the flexible hoses 42, the fountains 25 with more than enough ink to satisfy the requirements of 3 maximum press speed and copy coverage.
  • the excess ink spills over the overflow outlets 32 and down into the trough 26.
  • the constantly overflowing ink maintains a uniform depth of ink in contact with the fountain roller 21 and the screen 43 screens out paper and other foreign matter.
  • the pan 27 is a self-contained, easily handled assembly made'up of an open topped tray 50 dimensioned to fit between the walls 29, the fountain roller 21, and above the trough screen 43.
  • the tray 50 is provided with rollers 51 journalled at each side which are adapted to ride in tracks 52 formed on the walls 29 at a vertical level permitting the pan 27 to be simply slid along the floor line 35, into the tracks and into operating position (see FIG. 1).
  • Each pan 27 includes a float valve 53 or other level sensing device for maintaining a constant level of ink within the tray 50 when the valve is connected to one of the plurality of hoses 54 running the width of the press from suitable sources of ink, for example colored ink.
  • a pump 55 is mounted on the back of the tray 50 with an inlet conduit 56 extending into the pan 50 and an outlet hose 57 that may be releasably coupled to the overlying overflow fountain 25 at the same point of the plate 28 at which the flexible hose 42 is adapted to be connected.
  • the hose 57 can be replaced by a relatively rigid, upstanding pipe curved to overlie the fountain 25 when the pan 27 is in operating position.
  • the pump 55 carries a driving gear 58 that is adapted to come into engagement with a powered gear 59 that is operated by a motor 60 mounted in the press.
  • the pan 27, with its integral pump 55, is incorporated into the press inking system by simply being slid into position, so that the gear 58 meshes with the motor gear 59, and connecting the hoses 54 and 57.
  • the pan 27 also includes a screen 62 overlying a part of the tray 50 to prevent paper scraps or other foreign material from getting into the ink and clogging the inlet conduit 56.
  • the screen 62 also has a vertically extending portion 63 which subdivides the tray 50 so as to completely surround the pump intake 56 yet permit unobstructed visual inspection of the ink level in the pan. This feature is useful when ink is added by hand, and it also permits the float valve to be readily serviced when ink is being fed through the line 54.
  • clamps 65 are pivoted on studs 66 at the outer edges of the Walls 29. Springs 67 urge the clamps 65 against the pan.
  • the press operator by grasping the clamp 65 and pulling it outwardly, can manually rotate it so that the outer edges of the clamp are brought to bear on the rear wall of the pan 27, thus releasably holding the pan in operating position.
  • the ink level in the pan 27 is maintained by the float valve 53.
  • the pump 55 supplies the fountain 25 with more ink than is required for printing and the excess overflows and spills over the outlets 32 back into the tray 50 so as to maintain a constant level of ink at the fountain roller 21.
  • the screen 62, 63 screens out large pieces of foreign material as the ink is circulated.
  • an inking arrangement comprising, in combination, a frame, a fountain roller journalled in said frame, means defining an overflow fountain adjacent said roller, a trough in said frame underlying said roller in position to receive ink overflowing from said fountain, first supply means including a conduit for selectively delivering ink to said trough, a level control valve in said trough and coupled to said conduit for maintaining a supply of ink in said trough, a screen over said trough, a pump associated with said trough and having a releasable coupling with said fountain for feeding ink from the trough directly to the fountain, a pair of horizontally spaced tracks secured to said frame between said overflow fountain and said trough, a pan having rollers journalled on the sides thereof removably supported on said tracks and above said screen, said pan having an open top disposed, and dimensioned so as to intercept substantially all of the ink overflowing from said fountain, when positioned within said frame on said tracks, second supply
