Definitions

  • the invention relates to the inking of printing machines with fatty ink.
  • An inking device which comprises a touching cylinder capable of being in contact with the printing form, a feeding cylinder having a rigid non-alveolate surface, means for bringing a substantial mass of ink into contact with the surface of the feed cylinder and without contact with the touch cylinder and means for rotating the feed cylinder with a tangential speed lower than that of the touch cylinder (publication EP-A 017 844).
  • This device also includes means for adjusting the thickness of the ink layer on the touching cylinder, but these means require numerous adjustments which do not take account of a variable which is the ink redeposited on this cylinder by the form d and which therefore varies according to the form of printing.
  • the main problem posed by the inking of an offset or typography press consists in regularly depositing, from a substantial mass of fatty ink, a layer of a few microns thick uniformly distributed over the printing parts of a printing cylinder. The ink thus deposited on this cylinder is then transferred to the paper, either directly in the case of typography, or indirectly, via a cylinder covered with a rubberized sheet called a blanket in the case of offset. .
  • the quantity of ink released at the right of each screw must correspond to the ink consumption taken by each transverse zone of the paper. For example, if the print has several strips printed in the longitudinal direction and separated transversely by spaces which must remain blank, the inkwell adjustment screws must be tightened in line with the white areas and more or less open in line with the areas printed, according to the color intensity of these bands.
  • a device in order to apply a thin film of a high viscosity ink on a rotary printing form, a device is used. as defined in the characterizing part of claim 1.
  • the wiper cylinder E is kept under pressure on the toucher T coated with a flexible material. These two cylinders rotate in the same direction of rotation so that the ink film included in the contact area m is driven in one direction by the cylinder E and in the other direction by the toucher T. This film is therefore somehow sheared in its thickness.
  • fig. 3 shows the variant corresponding to the first certificate of addition of the aforementioned patent.
  • the laminating cylinder L has been removed and the wiping cylinder E remains, but to avoid the return of the ink coming from the reserve on the sheared layer, two rakes R1 and R2 have been arranged which clean the surface of the wiping cylinder E before that it does not come into contact with the layer spread on the touchpad T.
  • FIG. 4a The device described in the last aforementioned patent is shown in FIG. 4a.
  • the wiper cylinder E has been reduced in diameter to increase the pressure on the ink film and reduce its thickness.
  • This cylinder has thus become a rod, still referenced E, which is kept in pressure over its entire length against the toucher T by a V-groove formed in a cross-member Tr.
  • the rakes R1 and R2 of the preceding device are replaced by the tangents x and y at the contact points of the rod E and its support Tr as shown in the diagram developed in FIG. 4b.
  • These contact lines are supposed to prevent the ink from passing and coming to superimpose the layer. sheared thickness e.
  • the thickness of the ink layer e is a few microns. A variation of 10% in this thickness results in a variation visible to the eye in the optical density of the printed product. It can therefore be seen that the links x and y must be perfectly sealed or allow only a tiny film of ink of constant thickness to pass, a film which is superimposed on the film e of the sheared ink.
  • the rod E does not rotate any more and can be replaced by a cylindrical surface of radius r maintained in pressure on the toucher T.
  • the thickness of sheared ink e then only depends on two factors, namely the radius r and penetration, apart from the usual factors such as ink viscosity, hardness of the flexible coating and speed V. When the speed increases, the penetration must therefore be increased. The limit is determined by the degradation of the touchpad surface.
  • the invention like the state of the art, uses a flexible surface touch cylinder coated with a thin film of ink and depositing it on the printing form, this thin layer being determined in contact between this touch and a rigid cylinder at different peripheral speed.
  • the ink is supplied at the point of contact while being carried by the surface of the touching cylinder, and partly withdrawn by the rigid cylinder, called for this reason wiping cylinder, in the invention on the contrary, the ink is supplied in the form of a calibrated film carried by the surface of the rigid cylinder, called for this reason the feed cylinder, and is spread at the point of contact with the touch cylinder.
  • the reserve g of fatty ink is not in contact with the touching cylinder T but on the contrary with a supplying cylinder A, as it appears in particular in FIGS. 6, 7, 8 and 10.
  • This mass g is between this feed cylinder A, a knife 1 and two cheeks 2 provided with indentations in an arc of a circle for bearing by interlocking transversely on the cylindrical surface of the feed cylinder A , which is naturally a rigid cylinder, preferably metallic.
  • the knife i is secured to the cheeks 2 by means of micrometric screws 3 making it possible to adjust the distance d, visible in particular in FIG. 9, between the generator of cylinder A and the edge of knife 1 very precisely.
  • the knife 1 is made integral, transversely with respect to the axis of the feed cylinder A, and by means of the screws 3 and a cross member 4, of the two cheeks 2 which bear on the cylinder A. in this way the distance d is independent of the inevitable runout of this cylinder.
  • the knife 1 is sharpened in the manner of a cutting tool, as shown in FIG. 9, with however a small rectified dish of width a close to a tenth of a millimeter so that the edge thus obtained is perfectly straight.
  • the knife 1 cuts a slice of ink of thickness d, independent of the speed of the cylinder or of the characteristics of the ink.
  • the knife edge never being in contact with the cylinder, no wear can result.
  • the thickness d can vary from 10 to 60 microns depending on the precision of the micrometric screws.
  • the cylinder A is movable and kept under pressure on the touch switch T, coated in the usual manner with a layer 5 of flexible material.
  • the differential speed of the surfaces in contact at point 7 is obtained in this example by a rotation in the same direction of these two cylinders as represented by the arrows in FIG. 6.
  • a doctor blade 6 eliminates from the periphery of the toucher T the ink not used by the printer form F and deposits it on the feed cylinder A which brings it back into the reserve g.
  • this licking can cause small clumps of ink at the periphery of the toucher, which can be reduced in a known manner by placing a cylinder 8 rolling at the periphery of the touching cylinder.
  • this cylinder 8 may prove to be insufficient to eliminate these clumps and obtain a perfectly uniform layer.
  • an equalizing cylinder 9 which is driven in the opposite direction of the touching cylinder at a peripheral speed V ′ close to the peripheral speed V of the toucher, either positively by gears or by simple contact. with the toucher.
  • this cylinder g is in contact with the feeder A. Its action does not in any way modify the balance of ink thicknesses defined by the above formula. As seen in fig.
  • the ink layer of thickness d arriving at the contact zone 10 between the equalizing cylinder 9 and the feed cylinder A is divided in two, one of which follows the curved path on the equalizing cylinder 9 to reach the zone 11 between the equalizing cylinder 9 and the toucher T, and the other follows the curved path, on the cylinder A, going from the zone 10 to the zone T, then another curved path on the touching cylinder T going from the zone 7 to zone 11. Due to the speed differences between V ′ and v there is shearing of the ink layer d in the zone 10, then lamination in the zone 11. Thus, the entire thickness has undergone an extremely effective lamination in 10, 7 and 11, thus avoiding any ink agglomeration at the periphery of the toucher.
  • this equalizing cylinder 9 can in a known manner be driven in an axial reciprocating movement to improve the regularity of the ink film and avoid the formation of possible streaks.
  • the equalizing cylinder 9 no longer rotates at the speed V 'close to V but at a speed close to y.
  • the spreading phenomenon which previously occurred in zone 7 (or 10) would occur in zone 11, and therefore it would no longer be necessary to have contact between the cylinders A and T in the zone 7.
  • the ink layer of calibrated thickness d fed at slow speed by the feed cylinder A can be spread over the touch cylinder T at a higher peripheral speed, ie directly in the case examined first , either indirectly in the case of the variant that we have just seen, without this going beyond the ambit of the invention.
  • the method according to the invention it can be seen that one is thus in control of the value of the thickness e qut becomes independent of the speed of the machine, insofar as the ratio v / V remains constant, and independent of the viscosity of the ink and its temperature, contrary to the state of the art.
  • the apparatus is moreover insensitive to wear, due on the one hand to the absence of contact between the knife 1 and the feed cylinder A, and on the other hand to the low speed of rotation of the cylinder A relative to to the T-touch.
  • a relatively simple material makes it possible to obtain both high inking precision and high working speed compatible with industrial exploitation.
  • the two cheeks 2 are independent and provided on their opposite faces with a groove 12 which does not open outwards and in which each of the ends of the cross member 4 is mounted and supported. 3 for micrometric adjustment of the knife 1, preferably with differential pitch.
  • This knife 1 is itself guided in parallel in these grooves 12 and mounted by means of balls 13 to allow a slight angular adaptation of each of the cheeks 2 relative to the knife 1.
  • Each of the cheeks 2 rests on the cylinder A by a thicker part in which is cut the cylindrical notch exposed above, and this thick part ends in an oblique shoulder 14 on which comes into contact a pusher 15 actuated by a spring 16 and itself sliding obliquely in a flange 17 carrying the journal bearing 18 of the cylinder A, a similar arrangement being provided at the other end of the cylinder.
  • the oblique thrust produced by the pushers 15 on the cheeks 2 produces both their tight application on the periphery of the cylinder A, and their mutual approximation until contact with the balls 13, the seal between the ends of the knife 1 and the cheeks being ensured by the nesting in the grooves 12 and by the functional force of application in the drive direction.
  • the two flanges 17 are integral with a cradle 19 oscillating about an axis 19a fixed in the frame 20.
  • the penetration of the cylinder A into the touchor T is ensured by a pushing device 21, constituted by a spring or by preferably by a double-acting cylinder allowing the pressurization and depressurization, and limited in amplitude by a stop screw 22.
  • the touching cylinder T rotating in the frame 20 in contact with the printing form F, is driven in the opposite direction and at the same tangential speed as the printing form P by means of gears 32 and 33.
  • From its shaft end 23 is preferably connected to a speed variator 24 making it possible to adjust the v / V ratio at will, and from this latter comes a pulley 25 driving by a belt 26-a larger pulley 27 already providing a stage reduction in the desired direction.
  • This pulley 27 drives a shaft 28 swiveling in a fixed bearing 29, which shaft is connected to the shaft end 30 of the feed cylinder A by means of an oldham constant velocity joint or the like tolerating the movements of the cradle 19.
  • the invention could also be used to apply any thin film of a viscous liquid, such as paint, glue, or the like, to any surface which is scrolled by rotation or translation.
  • a viscous liquid such as paint, glue, or the like
