Definitions

  • the invention relates to metering devices in ink fountains of offset printing machines for zonal setting of the ink layer thickness on the ductor by changing the distance between the metering elements designed as metering elements and the ductor surface, the metering elements being supported on the ductor via respective supporting elements and independently of one another continuously by a prestressing force are pressed against the ductor surface so that the support surfaces of the metering devices form the reference surfaces for the adjustment of the metering elements.
  • the supply of the printing inks to the inking unit of an offset printing press is usually regulated by changing the ink layer thickness on the ductor.
  • By zonally dividing the dosing elements to adjust the ink layer thickness the different ink requirements across the printing width can be determined.
  • the accuracy and reproducibility of the setting of the individual dosing elements depends on various factors. Above all, manufacturing inaccuracies, wear and temperature influences in the area of the ink fountain, i.e. on metering elements, ductor and duct bearing, must be taken into account. One has therefore started to support the dosing elements on the ductor itself. This means that a dosing element can follow all manufacturing inaccuracies and heat influences directly, so that they have no influence on the setting of the ink layer thickness.
  • Metering elements of this type are already known from DE-AS 2 648 098. There, essentially one-piece metering elements have been provided with supporting and metering areas lying side by side in the direction of the duct axis. The dosing elements rest against the ink fountain roller by means of spring pressure with the interposition of a film over their support areas. These dosing elements must be adjusted tangentially to the ink fountain roller and therefore have wedge-shaped dosing areas that do not extend across the full zone width.
  • the dosing elements themselves are cylindrical or flat and are individually supported and adjustable independently of one another.
  • the metering areas are formed as zone-wide metering edges on individually, spring-supported metering elements.
  • the support areas open a flow opening through which the ink passes and from which. downstream metering edges is distributed over the full zone width.
  • a film is interposed to cover the metering elements.
  • DE-PS 3 018 784 describes the possibility of storing all the metering elements of a paint box on a continuous, flexible, support bar provided with rigid support webs.
  • the support bar is cushioned and is pressed against the ink fountain roller with the support bars.
  • the dosing elements are moved tangentially to the ink fountain roller to adjust the ink layer thickness.
  • the dosing elements are also covered by a film.
  • the arrangement tangential to the ductor creates a long wedge gap in which the ink is drawn in through the ductor from the ink fountain.
  • the tribological conditions are now such that a large pressure is built up there, similar to a lubricating gap in a hydrodynamic plain bearing.
  • the greatest pressure is definitely created when the dosing element is in the zero position and the ink guide is switched off.
  • the hydrodynamic pressure is reduced through its relatively large opening.
  • the resilient support in the zero position must be designed in accordance with the hydrodynamic pressure occurring in the metering gap, and thus the greatest possible resulting force occurring in the most unfavorable state.
  • this force is reduced because the hydrodynamic pressure is reduced.
  • the resultant of the spring force and the pressure force from the hydrodynamic pressure of the paint then becomes an adjusting force that is supported on the duct via the support areas of the metering elements.
  • the dosing element is fully open, however, the largest part of the support force is applied to the support areas as the contact force. This also increases the positioning force of the dosing elements.
  • the positioning force is composed of the proportions of the frictional forces between the metering element and its support or between the support areas and the ductor. Only the proportion or friction between the support areas and the ductor can be reduced by correspondingly high pressure forces in the metering gap. This is not the case only with the continuous support bar, which has other disadvantages.
  • the film inserted between the doctor and the dosing elements can also help to reduce friction.
  • the function of the dosing elements can, however, only be guaranteed if the film completely adapts to the contour of the dosing areas. With a stable, wear-resistant film, this requires a correspondingly high hydrodynamic pressure. In this case, the contact force of the dosing elements against the ductor is already greatly reduced.
  • a stable film also increases the level of forces in the metering gap. This naturally results in increased wear on the film over the support areas of the metering elements. With a more flexible film, the wear will be similar at a somewhat lower force level. Due to the wear due to the high level of force at the support points, however, a constant readjustment of the dosing elements is necessary.
  • a tensioning device for the film has already been shown in DE-OS 2 928 125 as an aid.
  • wear is not limited to the film.
  • the support areas of the dosing elements and especially the surface of the ductor are also affected by the constant stress.
  • punctiform support points are subject to a continuous movement sequence.
  • the wear on the dosing element itself is distributed by adjusting it.
  • the continuous support bar With the continuous support bar, no frictional forces are generated between the metering element and the ductor, but the friction of the ductor surface on the support areas of the support webs remains concentrated on the same points and increases wear there.
  • the continuous support bar is also disadvantageous because it is not possible to replace individual worn webs separately. It is also questionable whether a continuous bar can be so flexible on the one hand that it easily deforms, but on the other hand has such rigid support webs that it can only approximately meet the described power conditions and wear conditions.
  • the invention is therefore based on the object of avoiding the disadvantages described while maintaining the advantages of assigning support areas and metering areas to a metering element.
  • the contact force of the support areas against the ductor and the positioning forces of the dosing elements are to be optimized.
  • the metering elements are designed as radial or nearly radial paint slides, connected to their supporting elements by means of a set screw and adjustable with respect to these supporting elements, the color gap being determined by the distance between the metering edge of the colored slide moving radially to the ductor opposite to the ductor surface.
  • the support element comprises the metering element in the form of a fork and is supported on the ductor with circular support surfaces.
  • the dosing element is guided both radially and axially to the ductor and is adjustable.
  • One variant has an adjusting screw which can be pushed through the metering element and which also functions as a support element.
  • the adjusting screw is extended so far that it extends through the metering element and is supported on the ductor with a wear-resistant, spherical tip.
  • the dosing edge of the dosing element is zone-wide here and the dosing elements form a smooth surface towards the ink fountain, since the support elements are arranged downstream of the dosing edges in the direction of the duct rotation.
  • the advantages of these devices are primarily the favorable hydrodynamic arrangement of the metering elements.
  • the hydrodynamic forces from the printing ink and the supporting forces of the dosing elements are largely decoupled.
  • the printing ink cannot build up high hydrodynamic pressures in the relatively wide wedge, which is open at a maximum of 90 ° to the metering gap, since it can flow back into the ink fountain from the ductor surface almost unhindered.
  • An arrangement of the dosing elements under the upper part of the ink fountain reduces the free area of the dosing elements towards the printing ink and thus also the area of application for forces from the hydrodynamic pressure of the printing ink in the dosing area.
  • the frictional conditions are significantly improved.
  • the support elements are not moved relative to the duct surface. The friction when adjusting the dosing elements does not occur on the duct surface, but only in the support and adjustment mechanism of the dosing element. Wear between the support element and the ductor is minimized.
  • the contact force is only required to overcome the friction in the support of the support element, on the other hand, a small pushing-off force from printing ink drawn under the narrow support surfaces has to be compensated for.
  • this lubricating film made of printing ink is deliberately tolerated in order to take advantage of additional wear protection on the support areas and duct surface.
  • the friction is distributed over a larger area at the cylindrical support areas. So only a very low surface pressure is generated at the doctor and the wear effect is very low.
  • no cover to the ink fountain is necessary, since the support elements and dosing elements form a smooth surface. Gaps at the seams, as is common today, can be filled with viscous grease or foam to ensure sufficient mobility of the elements. This is possible because the dosing elements only have a very small stroke, which directly determines the color gap here and is not subject to translation through an angular position.
  • FIG. 1 the arrangement of the entire color box is shown.
  • Color sliders 3 are set on a ductor 1 of a paint box 2.
  • the dosing edge 4 is positioned slightly below the radial line 5 on the ductor 1.
  • the ink slides 3 are arranged between the upper part 6 and the lower part 7 of the ink fountain 7 in their longitudinal extent parallel to the line 5.
  • the ink slide 3 is supported on a retaining bar 8 which is firmly connected to the ink fountain lower part 7.
  • springs 10 are attached to guide rods 9 for positioning the paint slide 3 on the ductor 1.
  • Arranged parallel to the guide rods 9 is an adjusting screw 11 for the paint slider 3, on the end of which a handwheel 12 or a clutch 13 is seated.
  • a servomotor 14 can be connected to the coupling 13.
  • the servomotor 14 is flanged to a holding plate 15.
  • the holding plate 15 is screwed to the ends of the guide rods 9.
  • the guide rods 9 are movably guided by the holding bar 8 and enable the entire structural unit to move in the longitudinal direction parallel to the radius 5 on the ductor.
  • the springs 10 are biased so far that the paint slider 3 together with guide rods 9, adjusting screw 11, handwheel 12 or clutch 13, servomotor 14 and holding plate 15 is turned against the ductor 1 and movements between the ink fountain lower part 7 and ductor 1 via the spring travel the springs 10 can be caught.
  • the detailed structure of the color slider 3 can be seen in FIGS. 2 and 3.
  • the color slide 3 is divided into a support element 16 and a metering element 17.
  • the support element 16 is fork-shaped and provided with a through hole 18, once set, through which the adjusting screw 11 is passed.
  • the adjusting screw 11 has a pin 19 and a collar 20 on the opposite side.
  • the springs 10 for positioning the support element 16 on the ductor 1 are arranged on the guide rods 9 and are supported on the one hand via support disks 22 on the retaining strip 8 and on the other hand on the support element 16.
  • the support element 16 itself is supported on the ductor surface via narrow circular support surfaces 23.
  • the retaining bar 8 is attached throughout the entire length of the ink fountain. It has openings for the guide rods 9 and the set screws 11.
  • the completely assembled paint slider 3 can be simply hung from above into the retaining bar 8 by tensioning the spring 10 against the retaining bar 8 by pulling back the support element 16. Then the paint slider 3 can be placed on the ink fountain lower part 7 and set against the ductor 1 via the springs 10.
  • each with two support elements 16 is arranged in mutually associated lateral recesses, each with a spacer bush 24, which is clamped via a locking washer 25 with a screw 26 on the ink fountain lower part 7.
  • the spacer bushing 24 holds the locking washer 25 at a short distance from the support elements 16, so that they can still be moved, but cannot tip over.
  • adjusting elements 17 can be provided in the support element 16 on both sides of the slender part of the T-shaped metering element in order to be able to fine-tune the position of the metering edge 4 relative to the duct surface.
  • the adjusting elements consist of an eccentric 27 with a threaded pin and adjusting slot and a clamping nut 28.
  • the threaded pins are mounted in the support element 16 and the eccentric 27 work together with the side surfaces of the metering element 17.
  • Cavities 29, 30 are in the ink fountain upper part 6 intended to accommodate the screws and adjustment means. These cavities 29, 30 can be filled with fat during operation.
  • the movement space 31 between the support element 16 and the metering element 17 can also be filled with grease or a suitable elastic mass for sealing purposes.
  • these are laterally provided with depressions 32, which are also filled with a suitable sealant. It can make sense to fill all cavities together.
  • the sealing means must not restrict the possibility of movement of the support elements 16 and the metering element 17.
  • the travel of the metering elements 17 are only very small.
  • the actuating forces should not be increased. In the case of the movement spaces 31 behind the metering element 17, a supporting effect can even be achieved by means of an elastic filling compound, so that the spring 21 between the support element 16 and the metering element 17 could be omitted.
  • the printing ink is therefore metered through the gap between the metering edge 4 and the ductor 1.
  • the gap width is changed by turning the set screw 11 in the metering element 17, in which the latter moves axially in accordance with the rotation of the set screw 11.
  • the metering edge 4 is sharp-edged and shears off the paint in a preselected layer thickness on the ductor 1.
  • the movement of the printing ink in the ink fountain 2 is almost unhindered. Only at the constriction due to the covering of the ink slide 3 with the ink fountain upper part 6 is there a hindrance and thus a certain pressure build-up from the hydrodynamics of the printing ink.
  • the resulting pressure is based on the upper part 6 of the ink fountain, the free surface of the ink slide 3 and the ductor 1.
  • the actuating forces of the metering elements 17 are practically not influenced by the low proportion of normal force from the hydrodynamic pressure of the printing ink.
  • the contact forces of the support elements 16 are not influenced at all by the hydrodynamic pressure of the printing ink.
  • the pressure conditions at the metering edge 4 of such an approximately radially positioned ink slide 3 have already been examined. With a determined pressure of 8 bar at the metering edge 4, with a slide width of 30 mm and a support length of 1 mm, the effective area is 0.3 cm 2 and thus a reaction of approx. 30 N from the hydrodynamics at the metering edge 4 on the paint slide 3.
  • a variant of the color slide 3 in FIGS. 4 and 5 has significant simplifications and better sealing.
  • the support element is integrated into the set screw 34 and basically represents its extension to the duct surface.
  • the metering element 35 is therefore provided in its longitudinal extent with a through hole 36 which has the thread for the set screw 34 at the beginning and below that Dosing edge 4 of the dosing element 35 ends.
  • the adjusting screw 34 is also provided with a pin 19 for connecting the servomotor 14 via a coupling 13 or for attaching a handwheel 12.
  • the guide rods 9, on which the holding plate 15 is screwed for attaching the servomotor 14, are pinned to the metering element 35 here.
  • the springs 10 for setting the ink slide 33 are in turn arranged on the guide rods 9 and are supported by support disks 22 on the holding bar 8 and the metering element 35.
  • the set screw has an extension of its thread on a sliding surface 37, which is mounted in the metering element 35 in the through bore 36 accordingly.
  • the tip of the set screw 34 is provided with a wear-resistant slider 38 which is exchangeable.
  • the slider 38 can be spherical.
  • the spacers 24 and lock washers 25 are attached with screws 26 in recesses of the metering elements 35 on the lower part 7 of the ink fountain.
  • the adjusting screw 34 When the adjusting screw 34 is rotated, it is supported, starting from the metering element 35 by the springs 10, via the slide 38 on the duct 1.
  • the dosing element 35 is either moved via the springs 10 to the duct 1 or via the adjusting screw 34 away from the duct 1.
  • the entire drive that is to say guide rods 9, holding plate 15, servomotor 14 and coupling 13, moves together with the dosing element 35 with respect to the adjusting screw 34.
  • a transition piece 39 is inserted between the coupling 13 and the adjusting screw 34.
  • This transition piece 39 is clamped in the coupling 13 with a pin 40 and has a bore 41 and two guide slots 42 toward the set screw 34. In the bore 41 the end of the screw 34 inserted. This is provided with a driver pin 43 which engages in the guide slots 42 of the transition piece 39.
  • the color slide 33 is supported behind the metering edge 4. This enables zone-wide metering and the ink slides offer a largely smooth surface towards the ink fountain or printing ink.
  • the seal is limited to just one point of contact between two paint slides. It is sufficient to provide corresponding depressions 44 on the adjacent metering elements 35, which are filled with a sealant that is resistant to printing ink. Since no adjustment means for guiding the metering elements 35 are necessary because of the long lateral guide surfaces 45, the ink fountain upper part 6 can be made correspondingly simpler.
  • the slide piece 38 in the paint slide 33 is replaced by an arrangement of support rollers 46 which are mounted on an axis 47.
  • the set screw 34 is rotatably mounted in the axis 47. Differential threads can also be provided in the dosing element 35 and in the axis 47 in order to improve the setting accuracy.
  • these strips are created by the two-sided support of the color slide 3 with the support element 16 via the support surfaces 23 on the duct surface.
  • the support surfaces 23 have a circular arc shape and can be used to build up a thin ink film with a lubricating effect in the inlet zone, i.e. seen at the beginning in the direction of rotation of the duct, be provided with a chamfer through which color can be drawn in. A strong color build-up, which would falsify the dosage, is not possible due to the small width of the support surfaces 23.
  • the support effect and surface pressure on the ductor, as well as a self-retaining effect by clamping the paint slide 3 between the ink fountain lower part 7 and the ductor 1, supported by its direction of rotation, can be changed.
  • the narrow streaks in the vector ink layer can easily be removed by rubbing.
  • the support in the form of the slide 38 is arranged downstream of the metering edge 4 of the paint slide 33. Behind the metering edge 4, a streak is created in the vector ink layer due to the displacement effect of the slide 38 on the adjusting screw 34 eliminates every dosage and recreates. However, the displaced printing ink is leveled when it is removed from the jack to the inking unit and finally returned to the ink layer when it is rubbed. In the spherical design of the slider 38 there is a very small contact surface to the duct 1, in the limit case only one point.
  • the disruption of the vector ink layer is therefore less significant than in the case of the circular support surfaces 23 of the basic version, especially since the transition between ink layer and disruption occurs more or less abruptly.
  • the disturbance of the ink metering can be regarded as insignificant overall, since the entire color layer of the ink is never removed.
  • a desirable thin layer of paint remains, which is used to lubricate the rubbing process. If support rollers 46 are arranged instead of the slider 38, the friction can be avoided entirely. The printing ink is then only displaced.
  • FIG. 8 shows a variation in the placement of a paint slide 48 on the ductor 1.
  • the task of permanent support on the Duktor 1 is solved here with the help of a weight.
  • the color slide 48 as shown in FIG. 1, is supported on the duct 1 by the fork-shaped support element 16.
  • the support element 16 is no longer directly supported, but instead is applied by a force on the set screw 11 via its collar 20.
  • the set screw 11 is again clamped with a spring 21 between the support element 16 and the metering element 17, so that the collar 20 always abuts the support element 16 and the thread play at the engagement of the set screw 11 in the metering element 17 is eliminated.
  • a force 49 exerted by a weight 49 now acts on the ink slide 48 arranged in this way and arranged approximately radially to the duct 1 on the ink fountain lower part 7.
  • the weight 49 is in a cavity 50 between the ink fountain lower part 7 and the holding plate 15 for the Servomotor 14 arranged and suspended in a recess 51 in the ink fountain lower part 7.
  • it is provided with an extension 52 on which a cylindrical bearing surface is attached as a support element 53 lying transversely to the greatest extent of the weight 49.
  • a cam 54 is attached, the Effective surface is supported on an adjustment shoulder 55 on the adjusting screw 11.
  • the weight 49 is suspended between the rear surface 56 of the recess 51 and the adjustment projection 55 in such a way that the adjustment cam 54 abuts the adjustment projection 55 and the center of gravity of the weight 49 is kept outside its rest position.
  • a rubber or gas spring could also be used instead of a helical spring.
  • the zone-wide metering can also be achieved with support elements arranged upstream of the metering edge. This creates a closed vector paint layer.
  • independent suspensions for the servomotor are also possible in order to relieve the position of the support elements from the weight of the actuators.
