Definitions
- a lifter inking unit of this type is known from DE 37 06 602 C2.
- the ink to be processed is from an ink fountain roller as an ink feed roller by means of an inking roller a first inking roller can be transferred as the first inking roller.
- an inking roller of the inking roller subordinate and has several on a plate cylinder adjacent inking rollers. It is in the direction of rotation of the plate cylinder with an upstream inking roller a downstream inking roller by an ink roller coupled.
- ink distribution roller in the inking unit roller arranged, which on the one hand with the ink feed (Ink fountain roller, inking roller and first inking roller) and on the other hand with a first and a parallel to it switched second roll train with at least one on Functional connection between the inking roller and the plate cylinder is.
- the invention has for its object a lifter inking unit to create for a printing press that has the disadvantages mentioned avoids that in particular a stable color management in the Inking unit allowed and a simple construction of the inking roller train allowed.
- the task is based on the training features of the main claim solved. Further training results from the subclaims.
- One advantage of the lifter inking unit according to the invention is that justifies that due to the simple structure a noticeable Reduction of the number of rollers within the inking roller train is achievable. It is also advantageous that through the lifting strip Color density fluctuations generated are noticeably reduced are. This means that even with a single drum roller with significantly less Number of ink rollers and / or ink rollers with relative stable roller guidance can be achieved with small roller diameters. It is also advantageous that the color flow in the Inking unit can be separated in time, especially on the first inking roller is and at the same time the one transferred from the inking roller Lifter strips as a uniform color film on the outer surface this first inking roller is already leveled. Finally, it is an advantage that the movement of the paint lifter with the movement of at least one on the first inking roller adjacent calender roll can be coupled, as a result the formation of the desired color film can be accelerated.
- an offset printing press is in a printing unit Inking unit 16 for inking a printing form on a plate cylinder 17 arranged.
- Inking unit 16 for inking a printing form on a plate cylinder 17 arranged.
- a dampening unit for the plate cylinder 17 14 assigned.
- the dampening unit 14 is by means of a switchable bridge roller 13 can be integrated into the inking unit 16.
- the printing unit and especially the inking unit 16 can also be operated in dry offset (waterless offset printing).
- the dampening unit 14 or at least the dampening roller separable from the plate cylinder 17 or at least from the dampening solution supply is separable or the printing unit is trained without dampening unit 14.
- the inking unit 16 includes from a drivable ink feed roller 1, with a color metering system, preferably a color box is in functional connection.
- An ink roller 2 is between the ink feed roller 1 and one in Inking 16 downstream first inking roller 8 oscillating arranged.
- the first inking roller 8 is preferably one axially oscillating friction roller.
- Parallel to the inking roller 2 a jack shaft 3 is arranged.
- the inking roller 2 is on both sides with their roller journals in a roller lever 4 stored, which with the frame-mounted lifter shaft 3 are coupled.
- the first inking roller 8 (first inking roller) is a Subordinate single drum roller 15 with a plurality of which Plate cylinder 17 assigned inking rollers 12 in Functional connection is.
- the first inking roller 8 is a first Calender roll 10 - arranged in constant contact on the roll circumference, that with a second inking roller 11, preferably formed as an ink roller, periodically in Functional connection can be brought.
- the second inking roller 11 follow, depending on the design of the inking unit 16, several ink transport rollers or inking rollers within the single drum 15, which is in functional connection with the inking rollers 12 are.
- the first inking unit roller 8 mounted on the frame has on both sides an axially aligned, first pivot joint 9, wherein each pivot joint 9 with a first rocker arm 6 laterally is coupled.
- the first rocker arms 6 carry on the one hand at least a first adjusting element 5 and on the other the bearings for the first calender roll accommodated therein 10.
- At least one first rocker arm 6 is preferred a force-storing first damping element 7 in functional connection.
- the first inking roller 8 is on the roller circumference the first calender roll 10 and additionally one downstream of the second calender roll 21.
- the first calender roll 10 is in turn periodic with the second inking roller 11 can be brought into functional connection.
- the second calender roll 21 is with a third inking roller 26, preferably one Ink roller, periodically connectable.
- the inking unit rollers 11, 26 can in turn have several ink transport rollers and / or ink roller within the Connect single drum roller 15.
- the inking rollers 11, 26 in direct connection with the inking rollers 12 and thus create a short single drum roller 15.
- the first calender roll 10 analogous to Figures 1 and 2 in the first rocker arms 6 arranged.
- the rocker arms 6 have again at least a first adjustment element 5 and preferred at least one associated damping element 7 on and are each mounted in a first swivel 9.
- the Swivel joints 9 are in addition to the coupling with the first rocker arms 6 each connected to a laterally arranged coupling 25, around the roll neck of the second calender roll 21 in storage.
- Each coupling 25 is in one each a second frame-mounted pivot joint 22 second rocker arm 27 coupled in terms of transmission technology.
- At least one second rocker arm 27 carries a second one Adjusting element 23, which with at least one roller lever 4th can be brought into functional connection.
- At least a paddock 25 is with an energy-storing second damping element 24 in functional connection.
- the mode of action is as follows.
- the inking roller 2 is controlled in terms of transmission technology in such a way that they move around the jack shaft 3 periodically swinging on the ink feed roller in the lifting cycle 1, e.g. an ink fountain roller, or the first inking roller 8 is present.
- the lifter inking unit has a first and an additional one second calender roll 10, 21, so the movement of the first calender roll 10 analogous to that already described Mode of action.
- the coupling 25 are each in the Rocker arms 6 rigidly connected so that the movement of the Calender rolls 10, 21 run synchronously.
- the second adjustment elements 23 are to the first adjustment elements 5 adjustable so that the roller lever 4 preferably synchronously operate the first and second rocker arms 6, 27, so that preferably the formation of the separation points 18 between first calender roller 10 and second inking roller 11 and between the second calender roller 21 and the third inking roller 26 can be synchronized.
- the leveling the lifting strip on the first inking roller 8 noticeable accelerated and this with a smaller number of Inking rollers.
- the third inking roller 26 is preferred as Ink roller formed, so the second calender roller 21 likewise a preferably adjustable, Allow axially changing stroke.
