Definitions

  • the invention relates to a drive mechanism on offset printing machines for axially reciprocating the first or the first and second rollers of a pair of rollers of a combined dampening and inking unit.
  • the object of the invention is to make it possible that only the first roller works as a friction roller during the first adjustment of the two rollers as connecting rollers between the dampening and inking units, while in the second setting when the rollers on the applicator roller of the dampening unit laterally rest against each other, both rollers work as friction rollers and that the drive mechanism for the axial reciprocation can be derived from the ink rubbing cylinder in a stroke.
  • the advantage of the invention consists in an optimally effective rubbing performance in the nip points of the two rollers, depending on the setting.
  • the device comprises a plate cylinder 1 which is supported by means of pins at both ends in side walls 32 of the printing press.
  • the pins are driven in a known manner, not shown in detail, by gearwheels arranged outside the side walls 32 from the main drive of the machine.
  • a water box is provided for supplying the dampening liquid, in which a water box roller 5 is partially immersed. The strength of the dampening liquid is adjusted by means of a metering roller 6.
  • the drawn film dampening unit 2, 5, 6 thus guides the dampening liquid directly onto the pressure plate of the plate cylinder 1 and in a very short way, so that the dampening solution evaporation is kept low.
  • the drive of the dampening unit rollers and also of the inking unit rollers is known and will not be explained in more detail. All dampening unit rollers 2, 5, 6 and the rollers 3, 4 between dampening unit and inking unit can be adjusted to one another, this being done in a known manner e.g. by mounting the rollers on adjustable eccentric bushings, by arranging adjusting screws, by attaching springs or by mutually tightening the bearing levers of the rollers.
  • a first bearing lever 10 which can be pivoted about the center of the ink rubbing cylinder 8 and is supported axially, for example, on the side walls 32, is mounted on both sides.
  • first bearing lever 10 Inside next to the first bearing lever 10 is supported on both sides on the pin of the ink cylinder 8 also in the axial direction around its center pivoted second bearing lever 11 is mounted, which receives the thru axle 12 of the second roller 4 of the two rollers 3, 4 in a bearing position open on one side by means of a roller lock 15.
  • a section 21 of the thru axle 12 in the region of the bearing point serves as the roller lock 15, which is flattened with two edges and can be inserted into the bearing point through a slot 19.
  • a swivel lever 9 is articulated on both sides in the vicinity of the end faces of the first roller 3 on a coaxial section of the plug-in axis 13 of the first roller 3 on a bushing 17, which additionally has the upper roller 4 at the upper end in a bearing position open on one side by means of a roller lock 14 records.
  • a section 20 of the thru axle 12 in the region of the bearing point serves as the roller lock 14, which is flattened with two edges and can be inserted into the bearing point through a slot 18.
  • Both slots 18, 19 and the flattened sections 20, 21 are angularly offset, so that the plug-in axis 12 remains locked in the pivot lever 9 when unlocking from the bearing lever 11, so that the second roller 4 is convertible and only in the changed position by rotating the Thru axis 12 'unlocked after loosening a pressure piece 31' and can thus be removed.
  • the pressure piece 31 fixes the pivot lever 9 on the thru axle 12 when the roller lock 15 is actuated.
  • a pin 29 with the thru-axle 12 is provided with the adjusting bore 30 between the levers 9 and 11 so that the axial position of the levers in the first position with connected inking and dampening units 10, 11 is firmly fixed relative to the side walls 32 of the printing press.
  • the roller lock 15 is opened by rotating the thru axle 12 by approximately 90 °, so that the second roller 4 is unlocked.
  • the swivel lever 9 has guide means 16, 17 in the form of the coaxial socket 17 on a portion of the thru-axle 13 and an elongated hole 16, the position of which is selected so that when rollers 3, 4 touch, the upper contact surface of the elongated hole 16 rests on the socket 17.
  • the bushing 17, as a spacer or securing bushing secures the inner rings of the rolling bearings of the first roller 3, which are schematically indicated with a cross in the drawing, in the axial direction on the thru axle 12. Accordingly, the rolling bearings of the second roller 4 are fixed in the axial direction by locking rings 22 .
  • the slot guide 16, 17 enables the second roller 4 to be moved by hand or, if appropriate, using suitable adjusting means (not shown in the drawing) from the first position, in contact with the roller 3 and the first inking cylinder for ink dampening switch to a second position, in which the second roller 4 'as a rider (tandem roller) with roller separation of the rollers 3, 4 lowered from the first roller 3 together with this side of the applicator roller 2 of the dampening unit.
  • the drive mechanism for axially reciprocating the first or the first and second rollers of the roller pair 3, 4 of a combined dampening and inking unit can be seen in FIGS. 3 to 6.
  • the first bearing lever 10 receives the thru axle 13 of the intermediate roller 3 on both sides in a bearing position open on one side by means of a roller lock 26 with a ball sleeve 34.
  • a roller 27 with an integrated spherical sleeve 34 serves as the roller lock 26, which can be inserted through the slot 13 carrying the roller 3 through a slot 28 into the bearing point of the first bearing lever 10 which is open on one side.
  • By turning the driver 27 is secured in the bearing.
  • the roller shell of the first roller 3 is rotatably received on the thru-axle 13 via roller bearings.
  • the swivel lever 9 has a narrow web 25 and a much wider web 24 in the direction of the second roller 4.
  • the narrow web 25 is Y-thick, while the wide web 24 is X-thick according to the drawing.
  • the coupling parts 23 have a long section A and a short section B with respect to the center of the thru axle 13, such that in the connecting position of the second roller 4 between the dampening and inking units, the narrow web 25 of the pivot lever 9 between the coupling parts 23 in the latter Section B comes to rest, and in the changed tandem roller position of the second roller 4 'on the applicator roller 2 of the dampening unit separated from the inking unit, the wide web 24 fits exactly between the coupling parts 23 in which section A comes to rest.
  • the first inking cylinder 8 is driven in the axial direction in a known manner via the drive tube 38, drive lever 40 and drive roller 39, which runs in the link 37.
  • the kinematic chain consisting of two distribution couplers 36, 47 consists of a pivotable roller lever 36 and an axially displaceable push rod 47.
  • the roller lever 36 slides in a wide slot 44 in the gearbox housing 41 of the dampening unit around a bolt 42.
  • the roller lever 36 has one end a driving roller 35, which is guided in the link 37 on the ink cylinder 8, while the other end of the pivotable roller lever 36 is pivotally supported by means of the bolt 42 on the gear housing 41 is.
  • a push rod 47 is articulated via a first driver connection 43, 45, 46, 48, which is guided in the direction of the plug-in axis 13 of the first roller 3 through the side walls 32 axially displaceably via ball sleeve 52 and via a second driver connection 49, 50 , 51 is articulated at the beginning of the thru axle 13.
  • the first driver connection 43, 45, 46, 48 has on the driver 43 a bolt-shaped part 46 which is rotatably mounted in the roller lever 36 and a prismatic part 48 which is slidably guided in a slot 45 of the push rod 47.
  • the second driver connection 49, 50, 51 has a prismatic part 51 on the second driver 49, which is slidably guided in a transverse slot 50 of the plug axis 13.
  • the distance b0 of the fulcrum of the bolt-shaped part 46 of the first driver 43 has been selected in the pivotable roller lever 36 to the fulcrum of the bolt 42 in accordance with the intended reduction gear ratio a0.
  • the difference in the thickness Y of the narrow web 25 from the thickness X of the wide web 24 of the pivot lever 9 is chosen to be somewhat smaller than twice the stroke a0 of the thru axle 13 of the first roller 3, while the distance between the coupling surfaces of the two coupling parts 23 corresponds to that Thickness X of the wide web 24 of the pivot lever 9 is selected.
