Definitions

  • the present invention relates to an inking device for a heliographic printing apparatus.
  • the inking devices of heliographic printing apparatuses known to date generally include a watering can allowing ink to flow on the peripheral surface of the engraved cylinder of the apparatus, which is hollowed out of cells distributed according to the pattern to print. These cells are located over the greater part of the length of the cylinder, the two end parts or "rockets" of the cylinder being on the other hand left smooth.
  • the watering can consists of an inclined plane connected to an ink source and it lets out, under the action of gravity alone, a quantity of ink sufficient for obtaining a force-feeding, this is that is to say a complete filling of all the cells of the engraved cylinder during the passage of these cells under the watering can. Due to the provision of this watering can, it is necessary to have, below the engraved cylinder, a receiving tank collecting the excess ink flowing from the watering can and into which plunges the lower part of the engraved cylinder.
  • Such a known inking device has a number of drawbacks.
  • the whole of the engraved cylinder plunges, at its lower part, in the ink contained in the receiving tank and therefore its two end parts or "rockets", not engraved, happen to be covered with ink which is projected as a result of the rotation of the engraved cylinder.
  • the speed of rotation of this engraved cylinder, and therefore the speed of operation of the device is limited to avoid excessive ink splashes.
  • the lower receptacle must be cleaned often, which is a fairly long and difficult operation.
  • the present invention aims to remedy these various drawbacks by providing an inking device of particularly simple design, facilitating the cleaning of the inkwell, making it possible to obtain an excellent force-feeding of the cells of the engraved cylinder and avoiding the use below. of the engraved cylinder, of a receiving tank and consequently the drawbacks entailed by this.
  • this inking device for a heliographic printing apparatus comprising a horizontal cylinder driven in rotation, most of the peripheral surface of which is engraved and has cells distributed according to the pattern to be printed and which must be stuffed with ink, at each turn, with a view to transferring this ink onto a tablecloth to be printed, is characterized in that it comprises a hollow ink distribution ramp, parallel to the engraved cylinder and adjacent to it over the entire length of its etched part, in the area of the downward movement of its generators, the internal volume of this distribution ramp being connected to a source of pressurized ink and communicating with an inking chamber delimited, in the horizontal direction, by the ink distribution ramp, and means for adjusting the thickness of the ink film formed from the inking chamber, on the peripheral surface of the engraved cylinder.
  • the inking chamber extends over a length less than that of the engraved cylinder so as to leave the two end parts of the engraved cylinder un inked and it is delimited at its two longitudinal ends, by radial closing plates with curved peripheral surfaces which are applied against the extreme parts of the engraved cylinder, on either side of its useful engraved central part.
  • the inking chamber is delimited, at its upper part, by a fixed flexible blade, above all the length of the ink distribution ramp, in a position inclined by with respect to the horizontal such that its free lower end is permanently applied against the peripheral surface of the engraved cylinder, under the effect of the pressure of the ink in the inking chamber.
  • a blade is removably attached to the body of the distribution ramp, in the vicinity of the peripheral surface of the engraved cylinder, it dips into the ink contained in the inking chamber and its edge. lower is located a short distance from the bottom of the inking chamber, in order to delimit an elongated lower orifice, parallel to the axis of the cylinder, of low height, for adjusting the thickness of the ink film deposited on the peripheral surface of the engraved cylinder.
  • the inking device is provided for a heliographic printing apparatus, which comprises, as shown in FIGS. 1 and 2, an engraved cylinder 1 with a horizontal axis, rotating in the direction of the needles a watch.
  • the greater part of the peripheral surface of this cylinder 1 is etched and has cells 2 distributed over this surface according to the pattern to be printed on a sheet A traveling between the engraved cylinder 1 and an upper counterpressure cylinder, tangent to the previous one, indicated in phantom in Figure 1.
  • Each of these cells is stuffed with ink following its passage through the inking device which is indicated as a whole by the reference 3 in the drawing.
  • the inking device 3 comprises a horizontal ink distribution ramp 4 which is mounted parallel to and adjacent to the engraved cylinder 1, over the entire length of its engraved part 1a.
  • this ink distribution ramp 4 is constituted by a tube whose horizontal axis is located in the horizontal plane P passing through the axis of the engraved cylinder 1.
  • the axis of the ink distribution tube 4 could be located at a short distance from the horizontal plane P, by being offset slightly upwards or downwards relative to this horizontal plane P.
  • the ink distribution tube 4 is mounted fixed, at its two ends, on slides 5 each of which can be moved radially and horizontally, relative to the engraved cylinder 1, on the frame of the device, by means of an adjustment screw 6 actuated by an adjustment button 7. This allows the ink distribution tube 4 to be moved horizontally and parallel to itself as a function of the printing format, that is to say of the diameter of the engraved cylinder 1, so that the tube 4 is always located in the immediate vicinity of engraved cylinder 1 whatever the diameter thereof.
  • the internal volume 8 of the tube 4 is connected to a source of pressurized ink (not shown in the drawing), which can be constituted by a pump sucking the ink into a reservoir and discharging it under pressure into a pipe connected to the volume internal 8 of the tube 4, at any point of this tube.
  • the pressurized ink filling the internal volume 8 of the tube 4 is transmitted to an inking chamber 9 extending over a length less than that of the engraved cylinder 1.
  • the ink passes through one or more longitudinal slots 10 formed in the upper left part (that is to say located on the side of the engraved cylinder 1) of the side wall 11 of the ink distribution tube 4 and opening into the inking chamber 9.
  • This inking 9 is delimited, in the horizontal direction, on one side by the etched peripheral surface 1a of the cylinder 1, in the zone of the downward movement of its generatrices, that is to say the right part of the cylinder 1 in the figures 1 and 2, and, on the other side, by the side wall 11 of the ink distribution tube 4.
  • the side wall 11 has a flat longitudinal face 12 which is inclined from bottom to top and from left to right in Figures 1 and 2, i.e. from cylinder 1 to the ink distribution tube 4.
  • Each longitudinal lumen 10 opens into the upper part of the inclined flat face 12 and it communicates the internal volume 8 of the tube 4 with the inking chamber 9.
  • This inking chamber under pressure 9 is delimited, at its upper part, by a flexible longitudinal blade 13 which extends over the entire length of the tube 4 while being inclined relative to the horizontal and substantially parallel to the inclined plane face 12, above and at distance from it.
  • This upper flexible blade 13 is fixed on an upper flat face 14 of the tube 4, which extends longitudinally along the side wall 11 of this tube.
  • This upper planar face 14 is formed in the part of the side wall 11 of the tube 4 which is located above the zone where the slots 10 are formed, and it is inclined, with respect to the horizontal, from bottom to top. and from left to right, that is to say from the engraved cylinder 1 to the tube 4, preferably being substantially parallel to the lower planar face 12.
  • the upper flexible blade 13 is kept locked, on its face d 'upper inclined support 14, by means of a block 15 immobilized by screws engaged in tapped holes provided in the side wall 11 of the tube 4.
  • the free lower end 13a of the blade 13 forms a longitudinal edge which extends horizontally along the peripheral surface of the engraved cylinder 1 and in contact with this surface, and it is situated substantially in the horizontal plane P or in the immediate vicinity thereof.
  • the flexible blade 13 is inclined upward relative to the radial plane P passing through its edge 13a in contact with the engraved cylinder 1.
  • the lower edge 13a of the flexible blade 13 is kept permanently pressed against the peripheral surface of the engraved cylinder 1, under the effect of the pressure of the ink present in the inking chamber 9, so that the flexible blade 13 plays in a way the role of a tight valve preventing at this place any ink leak up when the engraved cylinder 1 rotates at low speed clockwise, as indicated by the arrows in Figures 1 and 2, or happens to be stopped .
  • the pressure inking chamber 9 is delimited by a rigid lower doctor blade 16 which is fixed, by means of screws, on an inclined plane face 17 extending longitudinally on the side wall 11 of the tube 4.
  • This face inclined plane 17 is substantially perpendicular to the plane face 12 to which it is connected and it therefore extends from bottom to top and from right to left in Figures 1 and 2, that is to say in the direction of the engraved cylinder 1.
  • the rigid lower doctor blade 16 has a flat upper face 16a which extends downwards and towards the cylinder 1 the flat face 12 of the tube 4 and which is more inclined, with respect to the horizontal, than this flat face 12.
  • the upper face 16a of the doctor blade 16 delimits, with the peripheral surface of the engraved cylinder 1 , a wedge-shaped space tapering towards the bottom.
  • the inclined upper face 11a of the doctor blade 16 is connected to a flat lower face 16b, inclined in the opposite direction, of the doctor blade 16, this inclined lower face 16b of the doctor blade 16 being substantially parallel to the flat face 17 of the side wall 11 of the tube 4.
  • the inclined plane faces 16a and 16b of the doctor blade 16 are connected along a longitudinal horizontal edge 16c. This edge 16c is located a short distance from the peripheral surface of the engraved cylinder 1, a distance which can be of the order of 3 to 4 tenths of a millimeter, for example.
  • the ink distribution tube 4 is integral with a radial closure plate 18, delimiting the inking chamber 9, with curved peripheral surface 18a whose radius of curvature is equal to the radius of curvature of the cylinder.
  • engraved 1 having the largest diameter, that is to say corresponding to the largest format.
  • Each radial closure plate 18 is applied against an end part 1b of the engraved cylinder 1, therefore on either side of the useful engraved central part 1a, and it is kept in abutment on this end part 1b because the sliders 5 , carrying between them the ink distribution tube 4, are biased, by means of the screws 6 and adjustment knobs 7, in the direction of the engraved cylinder 1.
  • An ink recovery sheet 19 is advantageously placed below the engraved cylinder 1.
  • This sheet 19 forms a sort of gutter, with a vertical concave cross section or open upwards, it extends parallel to the engraved cylinder 1 and its ends are free, allowing the collected ink to fall out of these places.
  • This arrangement makes it possible, with respect to conventional gutters closed at their two ends and in which the engraved cylinder is found, to avoid smearing by ink of the cheeks or front faces of the engraved cylinder and the ink projections which result therefrom.
  • this inking device also comprises a doctor blade 20, extending longitudinally, which is in contact with the peripheral surface of the engraved cylinder 1, in the upper left quadrant, to remove the ink in excess present on the etched peripheral surface 1a before the printing operation.
  • the inking device 3 comprises an ink distribution ramp 21 which comprises a body 22 parallel to the engraved cylinder 1 and of substantially parallelepiped shape.
  • This body 22 is hollowed out, in its part which is adjacent to the engraved cylinder 1, with an inking chamber 23 open towards the etched peripheral surface 1a of the cylinder 1 and limited, on the other side, by a substantially vertical wall 24 of the block 22 and, at its lower part, by a horizontal bottom 25 or substantially inclined downward towards the engraved cylinder 1.
  • a substantially vertical blade 26 which is parallel to the axis of the engraved cylinder 1 and block 22 and whose lower horizontal edge 26a is located a short distance, for example equal to 1 millimeter, above the bottom 25 of the inking chamber 23.
  • the blade 26 may constitute l substantially vertical wing of an angle iron whose other upper wing 26b is removably fixed on the upper surface 22a of the block 22. This fixing can be achieved by means of at least one locking button 27 extended by a threaded rod 28 screwed into a tapped hole formed in the block 22.
  • a support plate 29 is interposed between each locking button 27 and the upper surface 22a of the block 22 and the upper wing 26b of the blade 26.
  • Means can be provided to adjust at will the height of the ink passage slot delimited between the lower edge 26a of the blade 26 and the bottom 25 of the inking chamber.
  • a notable advantage of the inking device according to the invention is that, when the device stops, everything is emptied automatically. In fact, due to the stopping of the ink pressurization pump, the ink which is inside the ink distribution manifold 4, 21 and in the inking chamber 9 , 23 flows by itself, under the effect of gravity, to the tank containing it. This allows better cleaning of the assembly.
