Definitions

  • This invention relates generally to means for cleaning the cylinders of printing machines, and relates more particularly to new and useful improvements in a cleaning device especially adaptable for use in removing ink, lint and foreign matter from the printing surface of a printing press cylinder.
  • offset presses have a gap in the blanket cylinder.
  • this gap is important in obtaining the sheet gripper action and can constitute as much as 25% of the circumferential surface of the cylinder.
  • a gap or interruption in the surface of the printing impression also exists, although it is reduced to a minimum, usually being less than one inch in length.
  • the mounting of the blanket cylinder journal is generally by means of an eccentric supported in the press frames which comprises the cylinder throwoff for the presses. Both of these factors-i.e., the cylinder gap and the eccentric mounting, whereby the cylinder surface assumes more than one position-res'ult in an interruption or change of position in the surface of the blanket cylinder as it rotates during the printing operation.
  • locating stops may be provided on the cleaner assembly itself or on the press frames. Since the cleaning mechanism must be held rigidly in position during the cleaning action, when the position of the cleaning elements is located by means of the blanket cylinder surface, the brushing or wiping action is affected by the release of pressure in the gap areas. Likewise, it is not satisfactory to provide locating stops on the cleaner assembly or the press frames since the blanket cylinder moves in an eccentric mounting.
  • Another object of this invention is to provide a new and improved blanket cylinder cleaner which may be used in both sheet-fed and web-fed offset printing press machines.
  • Another object of this invention is to provide a new an improved printing cylinder cleaner assembly wherein the assembly is held rigidly in position during the cleaning action unaffected by the gap in a blanket cylinder or the eccentric mounting of a blanket cylinder.
  • Another object of this, invention is to provide a new and improved printing cylinder cleaner assembly wherein the assembly is held rigidly in position for cleaning by bearing against a fixed, uninterrupted locating surface.
  • Another object of this invention is to provide a new and improved printing cylinder cleaner which applies the cleaning fluid to the cylinder without contamination from the materials previously removed from the cylinder surface.
  • Another object of this invention is to provide a new and improved printing cylinder cleaner assembly wherein a predetermined measurable quantity of cleaning fluid is applied to the cylinder surface.
  • Another object of this invention is to provide a new and improved printing cylinder cleaner assembly having improved distribution of the cleaning fluid on the printing surface.
  • Another object of this invention is to provide a new and improved printing cylinder cleaner assembly which provides a self-cleaning action for the cleaning element.
  • the present invention is characterized by a novel and improved printing cylinder cleaner construction wherein the cleaning elements, preferably including both brush and wiper rollers, supported and enclosed in a pivotal housing assembly, are located ip their respective operative positions by positive positioning or stop means engaging the bearer of the printing cylinder.
  • the stop means may preferably comprise roller assemblies mountedon the top and bottom walls of the cleaner housing assembly by adjustable bracket means.
  • the rotary brush vibrates as it rotates, and is mounted so as to rotate with its bristles in peripheral contact with a cleaning shaft, open-end trough and, when in operative position for brushing action, the cylindrical surface of the printing cylinder.
  • Means are provided for supplying a predetermined, measurable quantity of cleaning fluid directly onto the upper surface area of the brush.
  • the cleaning action is performed solely by the brush element.
  • the brush is mounted in a pivotal enclosure and located in operative position as previously described and is supplied with cleaning fluid also in the manner previously described.
  • FIGURE 1 is a side elevation of a cleaner assembly embodying the present invention, shown in the inoperative position, in relation to a fragmentary portion of the blanket cylinder of a sheet-fed offset printing press machine;
  • FIGURE 2 is afragmentary view in end elevation, partly diagrammatic and partly in section, of the cleaner assembly of FIGURE 1, the assembly housing broken away to illustrate the cleaning elements;
  • FIGURE 3 is a sectional view taken along line III-III of FIGURE 2 showing details of the cam mounting of the brush roller providing reciprocative rotation for the brush;
  • FIGURE 4 is a sectional view taken through the longitudinal central portion of the cleaner assembly of FIG- URE 1, illustrating the relationship of the cleaner elements and showing details of the cleaning fluid injection tube and positioning of the open-end trough beneath, and in contact with, the cleaner brush.

  • stop means are provided for engaging the bearer 13 of the blanket cylinder 12 so as to provide a fixed, uninterrupted locating surface for rigidly positioning the cleaner assembly in operative position for cleaning the blanket cylinder surface.
  • this means comprises roller assemblies 50, 51 provided on the forward ends of adjustable bracket arms 55, 56 mounted on the top wall 52 at both ends of upper housing frame 26 and on the bottom wall 53 at both ends of lower housing frame 21, respectively.
  • the respective pivotal connections 46 and 34 between casing 45 and piston rod 43 are arranged in such manner that the pneumatic cylinder 40 positions the cleaner assembly 10 either in an inoperative position, in position for a brushing action or in position for a wiping action.
  • the assembly assumes the inoperative position illustrated in FIGURE 1.
  • cylinder 46 is charged through fluid hose line 42 whereby casing 45 pivots the assembly about trunnion 30 until rotary stop 51 engages bearer 13 thereby bringing brush 58 into brushing engagement with the cylindrical surface of blanket cylinder 12.
  • Brush 58 is carried by shaft 61 having a cylindrical cam 62 on one end thereof, illustrated in FIGURES 2 and 3, shaft 61 terminating in a trunnion 63 journaled in bearings 64 of bearing block 65 suitably rigidly mounted to side wall 26.
  • a cam follower 66 is mounted to end plate 23 by means of a support bracket 67 suitably secured thereto and having a threaded borehole to receive adjustment screw 68 from which follower 66 extends. Cam follower 66 may thereby be adjustably located to ride in the channelled cam profile surface 69 of cam 62.
  • shaft 61 The opposite end of shaft 61 is provided with suitable gear means (not shown) in meshed relationship with a suitable drive assembly, such as that shown and described in our Patent 3,049,997, granted Aug. 21, 1962, for rotating the brush in a direction opposite to the direction of rotation of the blanket cylinder.
  • a suitable drive assembly such as that shown and described in our Patent 3,049,997, granted Aug. 21, 1962, for rotating the brush in a direction opposite to the direction of rotation of the blanket cylinder.
  • the bristles of brush 58 are preferably wound on the shaft in a helix pattern illustrated in FIGURE 2, presenting a helical brushing action to the blanket cylinder surface which combines with the reciprocative vibratory motion to provide a scrubbing action, effectively cleaning the blanket surface.
  • Trough 70 is open-ended, extending substantially the full length of the cleaner housing though terminating short of side walls 26.
  • the bristles of brush 58 also peripherally engage near their upper surface a cleaner shaft 75 which is preferably a stationary rod having a knurled surface, mounted to end plate 23 and cleaning fluid channel bracket 82, more fully described hereinbelow, by means of locknut 76 and screw 77, respectively, or by any other suitable means.
  • a cleaner shaft 75 which is preferably a stationary rod having a knurled surface, mounted to end plate 23 and cleaning fluid channel bracket 82, more fully described hereinbelow, by means of locknut 76 and screw 77, respectively, or by any other suitable means.
  • this means comprises a fluid tube 80 located in an applicator channel 81 mounted ona bracket 82 extending from end plate 23 substantially over brush 58 and in close, spaced relationship thereto.
  • Tube 80 is connected through suitable fittings 83 and connecting line 84 to a pump (not shown) capable of delivering a measurable quantity of cleaning fluid with a timed cycle of operation.
  • the pump is preferably of a mechanically actuated fluid injector type, although any simple motorized rotary pump may be suitable.
  • Cleaning fluid is injected into applicator tube and distributed through holes 85 therein to fill the applicator channel 81, whereupon the fluid is fed by gravity feed through registering apertures 86, 87 in the channel 81 and channel bracket 82, respectively, onto the upper surface of brush 58.
  • Applicator channel 81 is provided with a cover 88 to prevent foreign matter from clogging the distributing apertures in the applicator tube, and to prevent overflow of the cleaning fluid.

  • a wiper roller 90 carried by shaft 91 terminating in a trunnion 92 journaled in suitable bearings 93 of bearing block 94 supported by supporting block 95 suitably fixed to side wall 26 and end plate 22. Since wiper roller 90 is frictionally driven upon contact with the surface of the blanket cylinder, identical mountings are provided at each end of the roller shaft.
  • a layer of rubber 96 or other suitable shock absorbent material is preferably provided on shaft 91 beneath the outer absorbent layer 97, preferably an absorbent cotton material.
  • a predetermined quantity of cleaning fluid is injected into the fluid applicator tube from where it is distributed throughout the applicator channel.
  • the pneumatic cylinders are charged so as to pivot the housing assembly until rotary stops 51 are brought into engagement with the bearer surface of the blanket cylinder to thereby bring brush 58 into engagement with the cylindrical surface of the blanket cylinder.
  • the pneumatic cylinders exert pressure through the rotary stops against the bearer surfaces to rigidly position the cleaner assembly during the brushing action, the position of the assembly thereby not being affected by the release of pressure in the gap areas or the eccentric mounting of the blanket cylinder journal as the blanket cylinder revolves.
  • the brush cleans and scrubs the blanket surface as the appropriate quantity of cleaning fluid continues to be applied to the bristles of the brush, the helical pattern of the brush bristles and the combined reciprocative rotating motion of the brush against the blanket providing an effective cleaning action.
  • the open-ended trough beneath the brush shimmed so that the bottom of the trough engages the periphery of the brush, combines with the lip of the channel bracket to evenly distribute the cleaning fluid to the brush, and continues to do so even when the gap area of the blanket cylinder is exposed to the brush during each revolution of the cylinder during the cleaning cycle.
  • the combination of the bottom of the trough and the knurled cleaning shaft in peripheral contact with the surface of the brush serves to remove foreign matter from the bristles of the brush which has in turn been removed from the surface of the blanket.
  • the cleaning of the blanket surface momentarily stops and a brush self-cleaning function takes place by the combination of the cleaner shaft and trough bottom engaging the brush bristles.
  • the pneumatic cylinders are thereafter charged so as to pivot the housing assembly in the opposite direction until rotary stops 50 are brought into engagement with the bearer of the blanket cylinder thereby bringing the wiper roller into contact with the cleaned blanket cylinder surface.
  • the assembly is held in rigid position during the wiping action.
  • the wiper roller may be eliminated and the cleaner comprised of a rotary brush only, mounted as illustrated in our preferred embodiment.
  • the brush would continue to revolve for a suitable period of time after the application of the cleaning fluid is stopped.
  • the cleaning shaft and the bottom of the open-ended trough combine to remove substantially all of the cleaning fluid and foreign matter dissolved therein from the bristles of the brush, thereby removing substantially all of the cleaning fluid from the surface of the blanket cylinder.
  • the fluid-free brush then serves as a wiper roller, not only to wipe off the cleaning fluid but also as a means to evaporate the fluid in addition to the wiping action. Any remaining traces of cleaning fluid on the blanket cylinder would be removed by the initial paper, web-fed through the printing machine.
