Definitions

  • ABSTRACT A mechanism for achieving adjustment and throwoff of the cylinders and rollers of a printing press which includes eccentric collars for mounting the plate cylinder and which includes sockets with adjustable stops for mounting the form rollers, the sockets being inwardly biased.
  • a cam ring which is generally concentric with the plate cylinder provides sloping stop surfaces, or cams, in the path of biased movement of the stops on the form roller sockets to position the sockets so that the form rollers have a desired width of flat with respect to the plate on the plate cylinder.
  • each form roller socket assembly has an arm, a bearing mount pivoted thereon, and an adjustable stop member.
  • a second adjusting screw, with a spring is interposed between the arm and the stop member for adjusting the roller with respect to the plate cylinder.
  • Each adjusting screw has a deeply detented seating member for shifting the screw endwise against its spring for achieving independent throw-off without affecting the adjusted condition of the screw.
  • a conventional letterpress' used in the; printing of .newspapers-and the like employsa,-printing couple consistingof a plate cylinder to which a printing plate is secured and an impression cylinder, with the web to be printed running between the two cylinders.
  • a film of .inkisconveyed tothe surface of the printing pla'teby -means of resiliently surfaced form rollers which run in contactwith the printing plate and also in contact'with thesurface of an ink drum to whichink is supplied by a series of rollers from an ink fountain
  • the-form roller is preferably pressed in the direction of the plate cylinder to form a flat.at the region of engagement with the plate.
  • the amount of pressure, as evidenced by width of flat is not critical in the case of stereotype plates in whichthe printing areas are in high relief. However in the case of chemically etched plates the relief is considerably less and there is 'ment. It is a moredetailed object in this connection to provide an inkroller socket assemblywhich not only permits precise adjustment of pressure and position but.
  • an object of the present invention toprovide means for precisely positioning a form roller with respect to its associated plate cylinderto establish a desired width of flat atthe region of engagementon start-up and to permit a fine adjustment of the position of the form roller to reestablish the desired width of flat after 'warm up and with the .press in motion. It is a re- ;lated object to provide a form roller adjusting means which permits simultaneous adjustment of flat width at two different form rollers using but a single, calibrated control at each end of the rollers.

  • FIGS. 1 and 2 there is shown a portion of a printing press of well-known type used for printing newspapers and the like having a printing couple which consists of a plate cylinder 11 and impression cylinder 12.
  • the plate cylinder has a stubshaft l3 centered on its axis 14 and which is mounted in a suitable bearinglS.
  • the bearing 15 is mounted in an eccentric collar 16 having an axis 17 and which is fitted in a circular bore 18 formed in the press side member or frame 20.
  • the collar is fitted with a retaining ring 21 on the left hand side and with a flange 22 on the right hand side which is secured to the collar by a series of cap screws 23.
  • the flange 22 is fitted with a connection 24-which is engaged by a thrust rod 25 connected to a conventional throw-off control diagramatically indicated, in FIG. 2a, at 26.
  • lt will be understood thatcorresponding structure including a stubshaft, bearing, collar and thrust rod are provided at the opposite end of the plate cylinder so that when the control 26 is operatedthe collars l6are rotated in the same direction and to equal degree.
  • the impression cylinder 12 has a stubshaft 33 for rotation about an axis 34 in a bearing 35 which is mounted in a fixed collar 36 secured to the frame plate by a circle of machine screws 37.
  • the shafts 13, 33 are rotated in unison by suitable driving means.
  • an ink feed system consisting of an ink fountain and a plurality of feed rollers (not shown) is provided terminating in a hard surfaced ink drum 40 having a shaft 41 which is journaled in the conventional way in the frame plates of the press.
  • a film of ink is conveyed from the ink drum 40 to the plate by a pair of resilient form rollers 42, 42a which are located on the opposite sides of the ink drum,and which, under running conditions, bear upon both the drum and plate so that the ink film on the plate'is constantly renewed.
  • the stubshaft 43 at the end of the roller is mounted in an ink roller socket generally indicated at 50 and shown in detail in FIGS. 3-6.
  • the socket includes an arm 51 (see especially FIG. 6) which is pivoted to the frame on a screw 52 which serves as a pivot pin and which is located in the region of engagement 53 of the form roller with the ink drum.
  • the remote end of the arm, indicated at 54, is biased in the direction of the plate cylinder by means of a spring 55 which is seated in a spring support 56 secured to'the frame by screws 57.
  • Pivoted to the arm on a stud 60 is a bearing mount 61 carrying an anti-friction bearing 62 for journaling the stubshaft 43 at the end of the roller.
  • the stud 60 on which the bearing mount is pivoted is located in the region of engagement 63 between the form roller and plate cylinder, with an adjusting screw for holding the bearing mount in a desired angular position.
  • the screw, indicated at 70 has a hexagonal head 71 in the form of a nut which is fixed to the screw by a pin 72.
  • the arm is provided with an extension 73 which mounts a supporting member 74 having a projecting portion, or post,
  • the screw is threadedinto a transversely threaded post 79 which carries a stud 80 extending through the bearing mount, the latter having at its end, a nut 81.
  • Providing clearance for the stud 80 is an arcuately shaped clearance opening 82 formed in the portion 73 of the arm.
  • the arm 51 of the socket is mounted for swinging movement about a mounting post 52 which is located in the region of engagement between the form roller and the ink drum, and a cam ring is provided at the end of the plate cylinder presenting a sloping cam surface which acts as a variable stop for positively positioning the arm of the ink roller socket thereby to permit variation of the width of flat on the form roller while the press is in motion.
  • an adjustable stop member is provided on the arm 51 effectively interposed between the socket structure and the cam surface on the ring.
  • a cam ring is positioned at the end of the plate cylinder encircling the stubshaft l3 and seated in a groove 91 formed in the collar 16 which supports the cylinder bearing.
  • a retaining flange 92 is secured by a circle of screws 93 to the inner axial end face of the collar.
  • the ring 90 is preferably formed in two half circles which are secured together by screws 94.
  • a sloping cam surface 95 Machined on the periphery of the ring 90 is a sloping cam surface 95 which serves as a variable stop surface for the socket. It will be noted that the cam surface 95 has a height hl at one end which is just slightly higher than the height h2 at the other end.
  • the arm 51 of the socket is held in working position by a stop member of arcuate shape having a stop 101 at the center portion thereof lying in the same plane as the cam surface 95 of the ring.
  • the stop member 100 is member 114 and thehead 111 of the screw is a de-' tented seating member .1 15.
  • the screw is maintained in its seated position by means of a coil spring .116 which seats on a nut 117 pinned to the central portion of the screwby a transversely extending pin .118.
  • the tip of the screw is screwed into a transversely threaded pivot 119 of circular shape which is captive in the arrn-51.
  • a second cam surface 95a is provided on the cam ring for engagement by a stop 101a on stop member 100a.
  • An identical adjusting screw assembly is interposed between the stop member 100a and the arm 51a, with corresponding elements being indicated by corresponding reference numerals with the addition of letter subscript.
  • an adjusting screw is provided which is secured to the frame of the press and which is coupled at its end to the ring.
  • the adjusting screw indicated at l0 is rotatable but axially captive in a mount 131 which is fixed with respect to the press frame 20.
  • the adjusting screw 130 carries an adjusting knob 132 while at its inner end the screw is threaded at 133 for engagement with a transversely threaded pivot pin which is mounted on an arm 135 integrally formed with the ring 90.
  • a stop 136 is provided on the frame in the path of movement of spaced stop surfaces defined by adjusting screws 137 138 mounted generally tangentially with respect to the ring.
  • adjusting screws 70, 70a are adjusted either backwardly or forwardly, so that the form rollers 42, 42a are in proper running engagement with respect to the ink drum 40.
  • the screws 110, 110a are adjusted with the plate in place on the plate cylinder so that a desired amount of pressure is applied against the plate in the regions of engagement 63, 63a, the desired pressure being that which produces thedesired width of flat on the form rollers.
  • the screw130 by its knob'l32,'is rotated in a. direction which will move the ring 90 clockwise, say, from the position indicated by the solid lines inFlG. 7 to the position indicated by the dotted lines.
  • a cam ring corresponding to the ring and an adjusting screw corresponding to the adjusting screw are provided at the opposite endof the plate cylinder for adjusting the sockets at the opposite end and that the knobs 132 at each end are identically calibrated so that a given amount of angular advancement of the knobs produces a corresponding change in the width of fiat, thereby insuring that the flat is of constant width along the entire length of the plate cylinder.
  • the width of flat may be monitored during the press run and corrective adjustment may be made by the knobs 132 from time to time. Or, as a result of experience in prior press runs, the adjusting knobs 132 may be rotated incrementally in accordance with a standard time schedule without necessity for monitoring.
  • the cam rings 90 (one at each end) are mounted on the collars 16 for rocking movement about an axis which is eccentric with respect to the axis of the plate cylinder so that when the collars are rocked in alined bores 18 in a direction to achieve throw-off, or separation, of the plate cylinder with respect to the impression cylinder, the cam surfaces 95, 95a on the cam ring move radially outward with respect to the axis of the plate cylinder thereby to shift the stops 101, 101a on the sockets outwardly to achieve simultaneous and automatic throw-off of the form rollers from the plate on the plate cylinder.
  • the ring axis 140 should be located remotely with respect to the collar or bore axis 17. In other words, the ring axis should lie beyond the plate axis 14 so that, for a given amount of rotation of the collar, the ring axis is displaced more than the axis of the plate cylinder.
  • the axes are horizontally arranged in the order of: bore (collar) axis 17, cylinder axis 14, and cam ring axis 140;
  • FIGS. 8 and 8a In order to understand how the automatic throw-off of the form rollers comes about, reference is made to FIGS. 8 and 8a.
  • the plate cylinder axis moves from the position 14 to the position 14a and the ring axis moves from the position 140 to the position 140a.
  • the ring axis is remote from the bore axis and since it starts its movement at a more favorable level (more favorable asfar as downward component is concerned) the ring is displaced downwardly (see FIG. 8a) by a greater amount than the corresponding portion of the plate cylinder.
  • separation, or throw-off occurs at the region 141 between the plate cylinder and the impression cylinder, throw-off occurs at the regions 63, 63a between the form roller and plate-cylinder.
  • the cam surface 95a moves to a new position 95a while the corresponding engaged portion of the plate cylinder moves from position 11-to position 11a. While the components of the motion are somewhat different in the case of the second form roller since it occupies a different peripheral position, with respect to the cluster of axes, nevertheless it will be apparent that the displacement of the cam surface, 95a and hence displacement of the form roller, is greater than the displacement at the engaged portion of theplate cylinder so that there is a net outward shift of the form roller 42a resulting in separation or throw-off at the region 63a.
  • the adjusting screw 70 which controls the pressure exerted between the form roller 42 and ink drum 40 incorporates a detented seating member, upon which the head of the screw is seated, which is rotatable between detents at different axial levels to bring about an endwise shifting movement of the adjusting screw accompanied by compression of the associated spring and independent throw-off between the form tented seating member upon which the screw heads 71 seats has a pair of axial projections 151, 152 which normally mate with deeply detented surfaces 153, 154.
  • the detented seating member 75 has the same profile as the head 71','both being hexagonal in the present instance, so that when the screw head 71 and the seating member 75 are both engaged by a deep socket wrench for simultaneous turning, the projections 151, 152 on the member 75 are cammed upwardly out of the deep detents 153, 154 into shallower detents 157, 158 which are at a higher level.
  • Such outward camming causes the adjusting screw 70 to be retracted endwise, thus causing the bearing mount 61, which is coupled by post 79 to the tip of the adjusting screw, to be drawn backwardly. This swings the bearing mount 61 about the stud 60 so that the form roller 62 breaks contact with the surface of the ink drum as indicated at 159 in FIG. 9.
  • the detented seating member 115 associated with the adjusting screw 110.
  • the seating member 115 interposed under the head 111 of the adjusting screw 110, has a pair of projections 161, 162 which are normally received in deep detents 163, 164.
  • the surface of the plate cylinder is freed for servicing or changing of printing plates.
  • the independent throw-off provided by the seating members 115, 115a is particularly advantageous in structures similar to the described but where the cam ring is concentric with the plate cylinder axis and which do not, therefore, have the feature of automatic throw-off of the form rollers. It is to be particularly noted that independent throwofl' provided by the seating members 75, and 75a, 115a, is achieved by bodily shifting of the adjusting screws without disturbing the condition of threaded adjustment.

  • the invention is particularly applicable to plates having only a shallow relief surrounding the printing areas, referred to as low relief plates.
