Definitions

  • the present invention relates to a printing machine, particularly a high speed ink supply mechanism for a printing machine.
  • the ink fountain roller is driven to rotate at a relatively slow peripheral speed as it picks up ink from the ink fountain.
  • the plate cylinder is driven so that it rotates at the relatively high surface speed of the running web to be printed.
  • the distribution roller and the other ink transfer rollers are driven via a common gear train with the plate cylinder and at a relatively high speed in comparison to the ink fountain roller.
  • the reciprocating lift roller is driven by surface contact with either the ink fountain roller or the friction roller depending on their position and therefore undergoes repeated changes in peripheral speed. As a result, the reciprocating lifting roller comes back from the ink fountain roller to the rubbing roller at a peripheral speed which is lower than that of the rubbing roller.
  • the present invention provides a printing unit in which a colored printing image is transferred away from a plate cylinder with a minimum of impairment caused by a change in the peripheral speed of a lifting roller.
  • a printing unit comprises an ink fountain containing a supply of ink, an ink fountain roller for receiving ink from the ink fountain, a first transfer roller, and a movable lifting roller for transferring ink from the ink fountain roller to the first transfer roller.
  • the lifting roller has a first position in which it is in ink-transferring contact with the ink fountain roller and a second position in which it is not in ink-transferring contact with the ink fountain roller.
  • a reciprocating mechanism is provided to move the lift roller between the first and second positions.
  • a second transfer roller is held in ink transfer contact with the first transfer roller and a plate cylinder is provided which carries the image to be printed.
  • a first drive mechanism drives the first transfer roller.
  • a second drive mechanism drives the second transfer roller and the plate cylinder independently of the drive of the first transfer roller.
  • the invention prevents the reciprocating lift roller from interfering with the rotation of the plate cylinder because the plate cylinder is driven independently of the drive of the transfer roller which is affected by the repeatedly changing speed of the reciprocating lift roller.
  • the drive mechanism preferably comprises a first gear mechanism for driving the first transfer roller, a first motor for driving the first gear mechanism, a second gear mechanism independent of the first gear mechanism for driving the second transfer roller and the plate cylinder, and a second motor for driving the second gear mechanism.
  • This arrangement ensures that the gear train which drives the second transfer roller and the plate cylinder is not affected by the changing speed of the reciprocating lifting roller.
  • This embodiment of the invention also prevents the reciprocating lifting roller from interfering with the rotation of the plate cylinder, since the plate cylinder has a drive independent of the drive of the first transfer roller and consequently it is not affected by the impact of the reciprocating ones Lift roller on the first transfer roller experienced.
  • the vibrating roller is held in a non-contact position so that it is not in ink-transferring contact with the second transfer roller when the lift roller strikes the first transfer roller. This ensures that the torsional vibration between the first and the second transfer roller surface is not transferred.
  • the vibrating roller is movable between a first position in which it is not in ink-transferring contact with the second transfer roller and a second position in which it is in ink-transferring contact with the second transfer roller.
  • a holding device is provided to keep the vibrating roller out of the second position when the lifting roller is in the first position.
  • the elevating roller and the vibrating roller are mounted together on a frame which is pivoted about the axis of the first transfer roller to move the elevating roller and the vibrating roller into their respective positions.
  • This alternative embodiment of the invention also prevents the lift roller from interfering with the rotation of the plate cylinder because the vibrating roller is kept out of ink transfer contact with the second transfer roller when the lift roller experiences a slowdown due to surface contact with the slower rotating ink fountain roller.
  • the printing unit 10 is, for example, an offset printing machine which comprises a plurality of rollers for transferring printing ink from an ink fountain 11 to a plate cylinder 12 which bears an image to be printed.
  • a blanket cylinder 14 transfers the inked print image from the plate cylinder 12 on the running paper web 16.
  • An ink fountain roller 18 receives ink from the ink fountain 11.
  • a lift roller 20 reciprocates between the ink fountain roller 18 and the first transfer roller 22 to transfer ink from the ink fountain roller 18 to the first transfer roller 22.
  • the first transfer roller 22 is an axially reciprocating friction roller.
  • the lifting roller 20 is moved between the ink fountain roller 18 and the first transfer roller 22 by a reciprocating mechanism 24.
  • the reciprocating mechanism 24 comprises a pivotable arm 26 which carries the lifting roller 20 and is mounted on a hub 28 for pivoting movement.
  • a reciprocating motor 29 moves the pivotable arm 26 around the hub 28 to repeatedly move the lift roller 20 in one cycle between the ink fountain roller 18 and the first transfer roller 22.
  • a second transfer roller 30 and a series of additional transfer rollers 32 transfer ink from the first transfer roller 22 to a group of applicator rollers 34, which in turn transfer the ink to the plate cylinder 12.
  • the printing unit 10 further comprises a fountain solution reservoir 40 and a series of dampening rollers 42 for transferring a dampening film to the plate cylinder 12.
  • a second blanket cylinder 44 is only partially shown in FIG. 1 to show a second printing unit for simultaneous printing on the other side of the paper web 16 .
  • the printing unit 10 also includes a series of drive mechanisms consisting of motors and gears for rotating the various rollers.
  • the gears assigned to the various rollers are shown schematically in the figures by circular dotted lines. Individual gears and gear mechanisms for rotating the rolls can be of conventional construction known to those skilled in the art.
  • An ink fountain roller motor 48 drives a gear mechanism 50 which rotates the ink fountain roller 18 at a relatively low peripheral speed to receive ink from the ink fountain 11.
  • the second transfer roller 30, the additional transfer rollers 32, the applicator roller 34, the plate cylinder 12 and the blanket cylinder 14 are connected by a common gear train 51 to be rotated together.
  • the conventional gear train 51 is independent of the gear mechanism 50.
  • a gear gear motor 52 drives the common gear train 51 so that each roller connected thereto rotates at a peripheral speed which is approximately the same as the speed of the running paper web 16.
  • a transfer roller motor 54 drives another gear mechanism 55 to rotate the first transfer roller 22 at a peripheral speed which is approximately the same as that of the running paper web. It is important that the transfer roller motor 54 and the further gear mechanism 55 rotate the first transfer roller 22, regardless of the rotation of the second transfer roller 30 and the other rollers which are driven together with the plate cylinder 12 by the gear train 51.
  • the dampening rollers 42 are driven in a conventional manner by a dampening roller motor 56 and an associated gear train 58.
  • the reciprocating mechanism 24 reciprocates the lift roller 20 between a first position shown in broken lines in FIG. 1 and a second position shown in solid lines.
  • the surface of the lifting roller 20 In the first position, the surface of the lifting roller 20 is in ink-transferring contact with the surface of the ink fountain roller 18.
  • the surface of the lifting roller 20 is also in rotationally driven contact with the surface of the rotating ink fountain roller 18. It goes without saying that in the state of the driven rotary contact there is a color film between the contacting roller surfaces.
  • the lift roller 20 is held in the first position by the reciprocating mechanism 24 to receive an amount of ink and then moved to the second position.
  • the lift roller 20 In the second position, the lift roller 20 is kept in rotational contact with the first transfer roller 22, with ink being transferred from the lift roller 20 to the first transfer roller 22 and then to the plate cylinder (12) and the blanket cylinder 14.
  • a lifting cycle is completed when the lifting roller 20 is moved back to the first position for ink transfer contact with the ink fountain roller 18 to pick up ink again.
  • the lift roller 20 In the first position, the lift roller 20 is driven by the relatively slow rotating ink fountain roller 18 and reaches a peripheral speed which is less than the peripheral speed of the first transfer roller 22.
  • the first transfer roller 22 accelerates the lifting roller 20 to the higher peripheral speed of the first transfer roller 22.
  • the impact of the slowly rotating lifting roller surface on the faster rotating transfer roller surface generates a torsional vibration which resists the uniform rotation of the first transfer roller 22 causes.
  • This gate ionic vibration is transmitted to the gear mechanism 55 which is driven by the transfer roller motor 54.
  • the reciprocating lifting roller 20 has this effect on the first transfer roller 22 and the gear mechanism 55 every time it is brought into contact with the first transfer roller 22.
  • the second transfer roller 30 and the subsequent rollers which transfer ink from the second transfer roller 30 to the plate cylinder 12, are rotated together by the common gear mechanism 51 regardless of the rotation of the first transfer roller 22 by the gear mechanism 55
  • the second transfer roller 30 and the subsequent rollers are isolated from the torsional vibration which is generated when the lifting roller 20 strikes the first transfer roller 22. In this way it is ensured that the inked printed image is transferred away from the plate cylinder 12 without experiencing interruptions caused by the repeated impacts of the reciprocating lifting roller 20.
  • a printing unit 70 according to an alternative embodiment of the present invention is shown schematically in FIG. 2.
  • the printing unit 70 comprises an ink fountain 71 with an ink fountain roller 72, a lifting roller 73, a first and a second transfer roller 74 and 75 and further transfer rollers 76, which lead to a plate cylinder (not shown).
  • the lift roller 73 is held in position by a frame 78 where it is in continuous ink transfer contact with the first transfer roller 74.
  • a regulating device comprises a bearing part 79, in which a journal shaft 80 of the lifting roller 73 is mounted.
  • the bearing part 79 is located in a slot 82 in the frame 78 and can be adjusted so that the support position of the lifting roller 73 with respect to the first transfer roller 74 can be radially regulated.
  • the frame 78 is mounted to pivot about the axis 84 of the first transfer roller 74 and is associated with a reciprocating mechanism 86 for movement between a first position shown in dashed lines and a second position shown in black lines.
  • the reciprocating mechanism 86 consists of a pivotable arm 88 which is connected to the frame 78 and is mounted on a hub 90 for the pivoting movement.
  • a reciprocating motor 91 moves the pivotable arm 88 about the hub 90 to move the frame 78 between the first and second positions in repeated cycles.
  • the lift roller 73 is held in ink transfer and rotational contact with the ink fountain roller 72 when the frame 78 is in the first position, and is prevented from contacting the ink fountain roller 72 when the frame 78 is in the second position.
  • the printing unit 70 also includes a device for rotating the rollers.
  • a gear transmission motor 92 drives a gear transmission 93, through which the second transfer roller 75 and the additional transfer rollers 76 are rotated together with the plate cylinder.
  • a separate transfer roller motor 94 drives a separate transmission mechanism 95 to rotate the first transfer roller 74 independently of the rollers which are driven by the gear transmission motor 92 via the gear transmission 93.
  • the lift roller 73 transfers ink to the first transfer roller 74 as they rotate in contact with each other.
  • the slowly moving surface of the ink fountain roller 72 causes resistance to the faster moving surface of the lift roller 73.
  • This creates a torsional vibration where the surface of the lifting roller 73 is in contact with the surface of the first transfer roller 74.
  • the torsional vibration is transmitted to the first transfer roller 74 and into the gear mechanism 95 which rotates the first transfer roller 74. Since the second transfer roller 75 is driven and rotated independently of the first, the torsional vibration is not transferred to the second transfer roller 75 and further via the gear train 93 to the plate cylinder.
  • the torsional vibrations generated by these repeated impacts of the lifting roller 73 on the ink fountain roller 72 do not impair the smooth transfer of the inked printed image away from the plate cylinder.
  • the regulating device enables that when the lifting roller 73 comes into contact with the first transfer roller 74, the pressing pressure on the contact surfaces can be regulated so that the lifting roller 73 is driven by the first transfer roller 74 and the lifting roller 73 simultaneously has a controlled slip with respect to the first transfer roller 74 is allowed in response to the resistance of the slow moving ink fountain roller 72 when the lift roller 73 is in the first position.
  • the degree to which the first transfer roller 74 passes through the lifting roller 73 drives rotating surface contact, reduced by the slip created when the lifting roller 73 strikes the ink fountain roller 72. This reduces the torsional vibration between the contacted surfaces of the lifting roller 73 and the first transfer roller 74.
  • a reduction in the amount of the torsional vibration also serves to avoid impairment of the rotating plate cylinder, since a strong vibration could hit the surfaces of the first and second transfer rollers 74 and 75 which are close to each other in color-transferring contact are transferred.
  • a printing unit 120 comprises an ink fountain 122 with an ink fountain roller 124, a lifting roller 126, a first transfer roller 128 and a second transfer roller 130 at a distance from the first transfer roller 128. Furthermore, the printing unit 120 comprises an arrangement of rollers 131 leading to the plate cylinder (not shown) and an oscillating roller 132.
