Definitions
- the invention relates to a dyeing or dampening unit of a rotary printing press with at least one applicator roller according to the preamble of claim 1.
- DE 33 42 853 C2 shows an inking unit in which an inking roller can be pivoted about a distribution cylinder and at the same time can be adjusted to a forme cylinder.
- the applicator roller is supported on both sides in levers.
- Adjustable stops against which the levers can be moved serve to adjust the application roller to the forme cylinder.
- a disadvantage is the effort for the adjustment and readjustment of the stops.
- the object is achieved in a generic inking or dampening unit according to the invention with the features of the independent claim.
- the application roller is placed against the forme cylinder with a defined force.
- This contact force (reaction force) maintains the balance force and adjusts itself automatically.
- the contact force can be selected and the setting of the so-called impression width can be made easily.
- the position is insensitive to the positional deviations of the inking or dampening unit compared to the forme cylinder, since the application roller automatically finds its balance through a corresponding swiveling. Readjustments are also possible independently in this way, e.g. B. with swelling or shrinkage of the application roller or changes in diameter due to thermal expansion.
- the invention will be explained in more detail using an exemplary embodiment.
- the single figure shows schematically an inking unit of a rotary printing press with an applicator roller which can be adjusted to a forme cylinder.
- the figure shows an inking unit 1, of which only one applicator roller 2 and one distribution cylinder 3 are shown.
- a wedge ink fountain 4 is also shown as an example of an ink source, from which ink is transported to the distribution cylinder 3 via ink delivery rollers 19, which are only indicated schematically.
- the applicator roller 2 is mounted on both sides with its pins 5, 6 in levers 7, 8.
- the levers 7, 8 are pivotable about the axis of rotation of the distribution cylinder 3.
- they are mounted, for example, on the journal of the distribution cylinder 3 or in side walls, not shown, in which the distribution cylinder 3 is also mounted.
- a linear motor in the form of a working cylinder 9, 10 each articulates on the levers 7, 8.
- a spring or an electrical pull magnet could also be used as the linear motor.
- the levers 7, 8 can also be acted on by means of a rotary motor, for example by means of an electric, pneumatic or hydraulic motor or based on spring force.
- a rotary motor 11 is thinly indicated in the figure with a position number in brackets.
- the application roller 2 can be pivoted to a forme cylinder 12 by pivoting the levers 7, 8.
- the working cylinders 9, 10 are preferably given a fluid Compressed air, supplied at a selected pressure p, the piston rods 13 of which extend and the levers 7, 8 together with the application roller 2 move into the position shown.
- the pressure p is selected so that the positioning force acting on the levers 7, 8 generates an abutment force which causes the desired impression width B of the application roller 2 on the forme cylinder 12.
- the position of the application roller 2 is then blocked by means of a blocking device 14.
- blocking devices 15 can also be arranged on the levers 7, 8.
- the blocking device 14 can also be released in the meantime in the course of the continuous printing, as a result of which the applicator roller 2 adjusts itself automatically in its employment, ie. H. in the case of, for example, swollen or shrunk application roller 2 or a change in diameter as a result of thermal expansion, the levers 7, 8 continue to adjust or retreat.
- the inking unit 1 can also be operated without blocking the application of the application roller 2, as a result of which there is a permanent, independent readjustment.
- the applicator roller 2 can be operated at a certain speed and for a certain period of time without blocking its position after it has been brought up to the forme cylinder 12 while the inking unit 1 is running in.
- the application roller 2 can z. B. yield initial unbalance due to uneven color distribution.
- the applicator roller 2 is initially also started with a higher setting force than later operation, in that the working cylinders 9, 10 are initially supplied with a higher pressure p. This avoids jobs that are too short due to static friction.
- the application roller 2 can also be placed on a forme cylinder 12.1 of a different diameter while maintaining the position of the inking unit 1. This case is also shown in dash-dotted lines in the figure.
- the swivel levers 7, 8 perform a larger swivel path when they are turned on until the applicator roller 2 comes to rest on the forme cylinder 12.1, which then takes place with approximately the same contact force and impression width B as on the larger forme cylinder 12.
- the application roller 2 can also be a dampening application roller of a dampening unit 18 (indicated by the clamp position).
