Definitions

  • the invention Since reversibility is a requirement in present day presses of the web printing continuous ink feeding type the invention has for its object to provide such presses with an improved mechanical arrangement of transfer rollers and pivoted journalling plates therefor which can be conveniently rocked by the operatorthereby making it possible to supply ink to a printing plate rotating in either direction from a fountain roller which rotates in. only one direction.
  • Another and more specific object of the invention resides in a new and improved combination which-will provide mechanical rneans for establishing the ink sup'ply for either normal or reverse operations by causing two ink transfer rollers to change their position relative to an ink drum automatically and quickly, requiring nothing Patented June 9, 1964 vention may consist of certain novel features of construction and operation, as will be more fully described and particularly pointed out in the specification, drawings and claims appended thereto.
  • FIGURE 1 is a side elevational view of. a half. deck including a printing couple designed for web printing and wherein the inking mechanism incorporates the improvement of the invention;
  • FIGURE 2 is a sectional view showing in elevation one position of the side plates and the ink transfer rollers journalled thereby;
  • FIGURE 3 is a sectional view similar to FIGURE 2 but showing the second operative position of the side plates and rollers;
  • FIGURE 4 is a side elevational view of the side plates only in the position they assume in FIGURE 2.
  • the half deck shown in this figure is merely one printing coupleof a unit turned on its side and supported above two conventional web printing units.
  • the units may also incorporate the improvements of the invention which will be described and explained with respect to the half, deck wherein'the numerals 10 and 11 indicate the, plateand impression cylinder respectively of the printing couple.
  • Inkis supplied to the plate cylinder 10 by a system of rollers and drums which essentially include an ink fountain 12located to the right of the printing couple at the terminal end of the frame members for the half deck and which frame members support the fountain 12 and the ink fountain roller 14 in the customary manner.
  • the roller 14 has associated therewith the doctor or'knife blade -15 ,which removes surplus 'ink, leaving however, a film of ink of controlled thickness on the fountain roller. It is accordingly necese sarythat the fountain roller rotate in one direction only and the'sarne is true'of the. ink pick-up, roller 16 in contact therewith.
  • Oneend of the first transfer roller 18 and also the second transfer roller 20 are journalled'by the side plates 22 and 24 shown in detail in FIGURES 2, 3 and '4 and which will be more particularly described.
  • the ink transferroller 18 more on the part of the operator than the pressing of a button or the actuation of a switch.
  • Another object in connection with web printing presses of the continuous feed type residesin a mechanical arrangement including side plates having a special mounting for limited rocking movement and which journal a pair of ink transfer rollers, wherebyone of said rollers is moved into and out of the operative chain of rollers for transferring the ink by a rocking of the side plates.
  • Another object of the invention resides in theprovision of ink transfer rollers and pivoted journalling plates therefor wherein the rollersrare journalled-by adjustable:
  • the side frames of the press, FIGURES 2 and 3, as indicated by numeral 32 have the stud shafts 33 projecting inwardly from the same and which are disposed with their centers on the axis of rotation for the ink pick-up roller 16.
  • a stud shaft 33v extends inwardly from eachframe just 'far enough to :provide a journal for one of the side plates such as 22.; On one side of its journal each' plate carries'a pair of small wheels 34- and 35 in spaced relation andiwhich havecontact with the cam surfaces 36 of the cam lever 37 .fiXed to the actuating shaft 38.
  • Said shaft extends across the press and a cam similar to 36 mounted thereon near the frame in which it is journalled, is actuated simultaneously withv cam surfaces 36 which are in contact with'the wheels 34 and 35, and thus effect a rocking of the side plates 22 on their journalling stud shafts 33.
  • This rocking of the side plates 22 in a counter-clockwise direction will change the position of the first transfer roller 18 with respect to both the second transfer roller 24? and the auixiliary drum 25.
  • the'roller 18 is i 7 moved from contact with the second transfer roller 2%
  • FIGURE 2 to a position as shown in FIGURE 3, wherein the roller 18 now contacts the drum 25.
  • the roller 18 is journalled at its respective ends by means ofsocket structures 45 shown generally in dotted lines in FIGURES '2 and 3.
  • Thefunction of the sockets is to adjustably support the roller lti'so that it bears with the desired pressure when in contact with the adjacent roller 2% and drum 25, respectively.
  • the rollers are admirs
  • Each socket structure includes the fixed section 71 and a movable section 72 pivoted to the former at 73.
  • the two sections as a unit provide the journal part 75 for receiving the shaft 68 and the combined sections are pivotally adjustable with respect to axis 73 as permitted by the elongated opening 77 which receives the securing means 78 for securing the socket structure to the plate 24.
  • Accordingrubber covered for the proper distribution and transfer of the ink and a socket supports each end of roller 18, the sockets being adjustable so as, to slightly shift the axis of the roller for proper pressure relation.
  • the socket structure includes a fixed section 45 and a pivoted section 47' which when inclosed relation provide the journal part 48 for receiving the shaft 54.? of the'roller 18.
  • the section 47' is pivoted'at 51 to the section 46 and the two sections as aunit are pivotally mounted on an eccentric stud rotatably mounted in a base or the like at 52.
  • the combined sections have adjustment with respect 1 to axis 52 as permitted by the elongated opening 53, and by rotation of the eccentric stud the operator is able to shift the axis of the roller 59 toward or away from opening' 53.
  • the entire socket' may be rotated about stud 52 to move roller 18 out of contact with adjacent rollers or drums.-- This may be done to facilitate testing contact pressures and it is necessary to loosen the'studs atb'oth '51 and 52 in order to rotate thesocket; I 1 7
  • the studs 57 secure the member 56 audi; pair of spaced stops 58 to the press side-frame 32 and since the projection is located between the stops they accordingly limit rockingrnovement of the side plates 22.
  • Each plate 22 ispivota1ly connectedto a plate-24 by the link 60,;the link having connection at itsrespective ends as at 61- and- 62 .to the of the auiiiliaryurum by being mounted on a ring 7 member 64fixed to the inside of frame32.
  • Each rn'ern' -l ber 64 is in'the form are ringto provide an openingfor the shaft of drum 25twhich extend's through the openings I for journalling by the sid e frames, spacing bares, fixed to each plate24 by the screws 66, provides an open- 1y, as shown in FIGURE 2, the transfer roller 20 is included in the inking mechanism as an active element performing itsnecessary function of transferring ink from roller 18 to'dr'um 25.
  • V j 7 To accommodate a reversal in the direction of rotation of the printing couple,ithe power cylinder 42 is actuated to oscillate cam lever 37 causing cam 3%?
  • roller 18 still maintains contact with the ink pick-up roller 16 and likewise roller 20 still maintains contact with the drum 25.
  • the. counter-clockwise rocking of plates 22 and the counterclockwise rocking of plates 24 due to the conthe auxiliary drum 25, conveniently functions as an ink distributing roller for the drum.
  • the same principle and general arrangement of the parts may be used in the inking mechanism for the units themselves or for the inking mechanism as used in a jcentercolor installation.
  • the shape of the side plates maybe varied to suit requirements, and the socket structures may also'bemodified to suit conditions. It will be appreciated, that to adapt the inking mechanism for continuous feeding from one direction of rotation to a reverse direction of rotation as regards the printing couple can be accomplished easily and quicklymerely by pushing a button at some convenientlocation on the press, and it will be further recognized that the operation, will require. a rninimun of time on the part of the attendant.
