Definitions

  • This invention may be employed in any printing machine that employs ink form rollers in the delivery of ink to the objects being printed.
  • ink is supplied by an inker system to the form rollers that are in contact with a plate cylinder.
  • the components of this system must be cleaned, and the setting of the form rollers to the plate cylinder and/or the vibrator rolls that supply ink to the form rollers must be adjusted.
  • FIGURE 1 is a side elevational view showing the form rollers in their operative position in contact with the plate cylinder.
  • FIGURE 2 is a side elevational view showing the form rollers in their inoperative position out of contact with the plate cylinder.
  • FIGURE 3 is an end view, partly sectional, taken along the line 3-3 of FIGURE 1 and showing means for adjusting the printing pressure between the form rollers and the plate cylinder.
  • FIGURE 4 is a sectional view taken along line 4-4 of FIGURE 5 and representing another embodiment of the means ,for adjusting the printing pressure between the platecylinder and the form rollers.
  • FIGURE 5 is an end view, partly sectional, of the apparatus shown in FIGURE 4 and taken along the line 5-5 of said FIGURE 4.
  • FIGURE 6 is an end view corresponding to that shown in .FIGURE 5 and representing another embodiment of this feature of the present invention.
  • form rollers are represented by the numeral 1.
  • form rollers 1 are shown in their operative position in contact with plate cylinder 2.
  • form rollers 1 are shown in their inoperative position out of contact with plate cylinder 2.
  • the form rollers are supplied with ink through vibrator rolls 15 that are in contact with the remainder of a conventional ink supply system, not shown.
  • Form rollers 1 are rotatably mounted on support shafts 4 which, in turn, are mounted between supporting brackets 3 positioned at each end of the form rollers. Supporting brackets 3 are pivotally mounted for rotation about pivot point 5.
  • each form roller 1 Also associated with each form roller 1 is a pivot shaft 6 having an eccentrically mounted sleeve 7, as shown more fully in FIGURE 3. Mounted on this eccentric sleeve 7 is link member 8. This link member is also secured to supporting brackets 3.
  • Pivot shaft 6 is rotatably mounted on frame 24 and attached at one end to block 9. This block is connected by means of connecting link 10 to connecting arm 11, which is pivotable about pivot point 12. The opposite end of connecting arm 11 is connected to the push rod 13 of air cylinder 14.
  • FIGURES 1 and 2 makes reference to the features of the invention at one end of the form rollers. It will be appreciated by those skilled in the art that the apparatus, not shown, at the opposite end of each form roller will be the same as that described and illustrated herein.
  • air cylinder 14 is, set so that push rod 13 may be moved between predetermined operative and inoperative positions.
  • form rollers 1 will be in contact with plate cylinder 2.
  • in the inoperative position form rollers 1 will be moved back to a position out of contact with the plate cylinder, thus facilitating cleaning or adjustment of the rollers as may be required from time to time.
  • connecting arm 11 is caused to pivot about its pivot point 12, causing connecting link 10 to move in an are about the center of pivot shaft 6.
  • the movement of connecting link 10 causes block 9 to likewise move in an art causing pivot shaft 6 to rotate.
  • pivot shaft 6 causes its eccentrically mounted sleeve 7 to swing in an arc.
  • Link member 8 is caused to move by the movement of eccentric sleeve 7.
  • link member 8 causes supporting brackets 3 to move about pivot point 5 to a position in which support shafts 4 and form rollers 1 mounted thereon are moved to a predetermined inoperative position in which form rollers 1 are out of contact with plate cylinder 2.
  • the present invention as heretofore described provides for the movement of the form rollers between fixed operative and inoperative positions. It is also highly desirable to have a fine adjustment feature that will enable the printing pressure between plate cylinder 2 and form rollers 1 to be adjusted. Likewise, it is desirable to provide some means for adjusting the printing pressure between form rollers 1 and vibrator rolls 15, the next rolls in the conventional inker system running back to the ink supply.
  • means for controlling the pressure between the form rollers and the plate cylinder is provided. This feature is best illustrated in FIGURE 3. In this embodiment, pivot shaft 6 is split into two separate portions 6a and 6b.
  • pivot shaft portion 6a is keyed to sleeve portion 7a by means of key 16a.
  • pivot shaft .portion 6a is supported by frame 24.
  • Pivot shaft portion 6a is keyed to eccentrically mounted sleeve 70 by means of key 160.
  • link member 8a is also secured to supporting bracket 3a.
  • Support shaft. 4 is mounted on supporting bracket 3a by means of pivotable bearing 30, which makes it possible to skew form roller 1 in order to overcome misalignment of the rollers.
  • a conventional, commercially-available spherical bearing may conveniently be employed as the pivotable bearing 30; It is also within the scope of this invention to include such pivotable bearings at each end of the form roller if desired.
  • Intimate locking between sleeve portion 7a and eccentric sleeve portion 7b is accomplished by means of adjustable clamping bolts 17 mounted either on eccentric sleeve portion 7b or on sleeve portion 7a.
  • clamping bolts 17 are adjusted so as to cause sleeve portion 7a to move slightly. This, in turn, causes rotation of pivot shaft portion 6a.
  • the rotation of shaft portion 6a causes rotation of eccentric sleeve 70 and movement of link member 8a at the Opposite end of the apparatus, causing movement of the various elements in the manner heretofore described.
  • Worm gear 20 is mounted upon and keyed to pivot shaft 6 in block 9.
  • Worm 21 is provided with adjusting bolt 22.
  • Clamping blot 23 is provided to assure a tight fit of the worm gear housing in block 9.
  • the block is secured to shaft 6, by means of bolt 25.
  • clamp bolt 23 is loosened, and adjusting bolt 22 is turned. This causes worm 21 to rotate worm gear 20, thereby causing pivot shaft 6 to rotate, thereby establishing new operative and inoperative positions.
  • a set of levers keyed to pivot shaft 6 may be used to affect rotation of the pivot shaft.
  • block 9 is secured to push rod 13 of air cylinder 14 by means of link 10.
  • Pivot shaft 6 mounted thereon is keyed to lever 27.
  • a set of adjusting bolts 28 and 29 are provided for adjusting the position of lever 27 and, consequently, of pivot shaft 6. Movement of air cylinder push rod 13 between its predetermined positions causes rotation of block 9 about the center of pivot shaft 6.
  • Eccentric sleeve 7 mounted thereon is thereby caused to move in an are as heretofore described.
  • adjusting bolts 28 and 29 may be adjusted so as to cause a desired amount of movement of lever 27 on pivot shaft 6. Since this lever is keyed to pivot shaft 6, the pivot shaft will also be rotated so as to establish a new predetermined operative and inoperative position. Adjusting the position of eccentric sleeve 7 by rotating pivot shaft 6 by means of lever 27, therefore, provides a convenient means for adjusting the desired printing pressure between the plate cylinder and the form rollers. It will be appreciated by those skilled in the art that the features disclosed in FIGURES 4-6- for adjusting pressure between the form rollers and the plate cylinders may be employed alone or in conjunction with the adjustment disclosed and illustrated in FIGURE 3.
  • rollers are in perfect alignment, pressure may be adjusted by simply employing either the feature shown in FIGURES 4 and 5 or that shown in FIGURE 6. In order to correct mis-alignment of the rollers, however, it is useful to employ the feature particularly set forth in FIGURE 3 for the reasons heretofore given.
  • support brackets pivotally mounted on said frame and positioned at one end opposite each of the form rollers, said support brackets each having a link member rigidly secured to another end of said support brackets, said link member having an opening there- 1n;
  • a pivot shaft rotatably mounted on said frame in spaced relationship to said support bracket pivot, said pivot shaft comprising a first and a second segment in axial relationship to each other, said second segment including a pivotable support bearing mounted on said support bracket at the opposite end of the form roller, and adapted to permit the support shaft to be pivoted, and adjusting means for rotating said second segment independent of said first segment so as to alter the relative rotational position of said second segment relative to said first segment;
  • a worm gear is rigidly mounted on said pivot shaft, ;a' worm is positioned in operative relationship with said. worm gear, and means for turning the worm is connected to said worm, whereby the worm gear may be turned, this rotating said pivot shaft so as to alter its predetermined operative and inoperative positions.
  • the apparatus of claim 1 including means for adjusting printing pressure between the form rollers and rollers that are supplying ink from the inker system directly onto said form rollers comprising:
  • adjustable clamping means for adjustably fixing said support shaft about its axis so as to cause said eccentric portion thereof to move in an are about the axis of said support shaft, whereby adjustment of said support shaft in one direction will cause the form roller mounted on said eccentric portion to move in such' a manner so as to increase pressure between it and the next roller in the inker system and whereas movement of said support shaft in the opposite direction will tend to decrease said pressure between the form and ink supply rollers.
  • the apparatus of claim 1 including a pivotable support bearing mounted on said support bracket at the operative end of said form roller.
