Definitions

  • the invention relates to a device on offset printing presses for converting the second (upper) intermediate roller of an intermediate roller pair connecting an inking unit to a dampening unit according to the preamble of the first claim.
  • An intermediate roller pair is also known from a research report No. 3.216 "Dampening unit examination" by the Federal Printing Association or the German Research Association for Printing and Reproduction Technology (FOGRA), page 30, Figure 38. Both dampening fluid and ink are applied to the plate cylinder via the dampening unit's application rollers. Such an operation is well suited for a number of printing jobs, e.g. for heavily covered subjects that do not tend to stenciling.
  • the object of the invention is to develop the generic device so that either two intermediate rollers can be assigned to a combined dampening and inking unit as connecting rollers or the applicator roller of the dampening unit as the first rider roller and second overrider roller (tandem roller), with the possibility of being in this roller position to insert a third intermediate roller in the bearing of the second intermediate roller converted to the application roller of the dampening unit as a tandem roller as an additional connecting roller to the inking unit in contact with the first intermediate roller which has not been converted.
  • the device With the first setting of the intermediate rollers 3, 4 as connecting rollers between the dampening and inking units, the device has four nip points to the first inking roller, the upper intermediate roller acting as a storage and smoothing roller on the first inking cylinder.
  • the second setting with intermediate rollers 3, 4 lying laterally on the applicator roller of the dampening unit stenciling due to channel reactions of the plate cylinder can be combated as a result of dampening and inking unit separation by means of the two rider rollers on the dampening unit application roller.
  • a paint-dampening unit connection is established again.
  • the latter setting enables the ink / fountain solution balance to be established very quickly and is also highly effective against stenciling in both the inking and dampening units.
  • the device comprises a plate cylinder 1, which is mounted 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 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 or the inking unit rollers is known and will not be explained in more detail. All dampening unit rollers 2, 5, 6 and the intermediate rollers 3, 4 between the dampening unit and inking unit can be adjusted to one another, this being done in a known manner, for example by mounting the rollers on adjustable eccentric bushings or by arranging set screws and / or by attaching springs or the like mutual bracing of the roller-receiving bearing levers can take place.
  • an axially pivotable e.g. supported on the side walls 32 supported bearing lever 10, which receives the thru axle 13 of the first intermediate roller 3 in a bearing position open on one side by means of a roller lock 26.
  • the thru axle 13 is secured in the bearing by turning.
  • the roller jacket of the first intermediate roller 3 is rotatably received on the thru axle via roller bearings.
  • a bearing lever 11 which can be pivoted about its center, is supported in the axial direction on both sides of the journal of the inking cylinder 8 and receives the thru axle 12 of the second (upper) intermediate roller 4 in a bearing position open on one side by means of a roller lock 15.
  • a pivot lever 9 is articulated, which on upper end in an open on one side bearing by means of a roller lock 14 additionally receives the upper intermediate roller 4.
  • the slots 18, 19 and the flattened sections 20, 21 are offset from one another 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 intermediate roller is convertible and only in the changed position by Turning the thru axle 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.
  • the roller lock 15 is opened by rotating the thru axle 12 by approximately 90 °, so that the second intermediate roller 4 is unlocked.
  • the pivot lever 9 has guide means 16, 17 in the form of the coaxial bushing 17 on a section of the thru-axle 13 and an elongated hole 16, the position of which is selected so that when the intermediate rollers 3, 4 touch, the upper contact surface of the elongated hole 16 on the bushing 17th sits on.
  • the bushing 17 at the same time secures the inner rings of the rolling bearings of the first intermediate roller 3, which are indicated schematically with a cross in the drawing, in the axial direction on the plug-in axis 12 as a spacer or locking bushing .
  • the second intermediate roller 4 From the first position in which there is contact with the lower intermediate roller 3 and the first ink rubbing cylinder 8 Ink dampening separation in a second position in which the second intermediate roller 4 'as a rider (tandem roller) with roller separation of the intermediate rollers 3, 4, ie while lowering the first intermediate roller 3 together with the latter, it is laterally attached to the applicator roller 2 of the dampening unit.
  • An axial support of the pivot lever 9 'in the second position of the second intermediate roller 4' is achieved by coupling surfaces of two radial coupling parts 23, engage in the coupling surfaces of a wide web 24 'of the pivot lever 9' when the second intermediate roller 4 'lowered as a tandem roller on the Application roller 2 of the dampening unit is set to the side.
  • the pivot lever 9 In the area of the elongated hole 16, the pivot lever 9 has a narrow web 25 which is Y-thick, while the substantially wider web 24 which is connected in the direction of the upper intermediate roller 4 is X-thick.
  • the coupling parts 23 are pinned to the thru-axle 13 at a distance X from one another.
  • the swivel lever 9 slides around the center of the thru-axle 13 via the bushing 17 and the slot 16 in a precisely fitting manner laterally on the applicator roller 2 between the coupling surfaces of the coupling parts 23 and is thus axially fixed exactly.
  • the two radial coupling parts 23 have a long section A and a short section B with respect to the center of the thru axle 13. If the second intermediate roller 4 is in the connecting position between the dampening unit and the inking unit, the Y-thick narrow web 25 comes Swivel lever 9 between the coupling parts 23 in its section B. If the second intermediate roller 4 is switched to the overreach (tandem) position 4 ', the X-thicker wider web 24 comes exactly between the long section A of the coupling parts 23.
  • the third intermediate roller 33 is received in a parking position between the side walls 32 of the printing press in the dampening unit and is only replaced when used in the bearing lever 11 for the converted second intermediate roller 4.
  • This further intermediate roller 33 is then designed without a pivot lever 9 on the thru axle 13, since it only needs to be removed from the roller lock 15 for parking in the dampening unit if no use is provided.
