Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to applying ink to a printing plate of a printing cylinder of a rotary printing press.
In an inking unit without an inking area, one or two ink lands assigned to the forme cylinder and having the same diameter as the forme cylinder are of the type having a roller and the ink land having an ink cylinder assigned to the roller. related to things.

The prior art and its disadvantages The problem in designing the so-called short inking units used, for example, for off-cent rotary printing presses, is that a thin uniform ink film of a few μm is continuously supplied to the printing plate. . In this case, the term "uniform" means that the ink film is applied to the printing plate in an even and uniform thickness over the entire width of the printing plate and the entire circumference of the printing cylinder and over the entire printing time.・Achieving and maintaining a thin ink thickness of several micrometers, especially with highly viscous ink, without producing a pattern phenomenon (so-called ink unevenness) is important for the quality of printed matter printed with such a printing machine. This is the basic condition for・The turn phenomenon is that the ink print tarts that have been reversely transferred from the printing plate to the inking device are not shifted in the circumferential direction and are reapplied to the printing plate together with the newly supplied ink film, resulting in new ink being applied to the printing plate. This refers to the difference in film thickness that appears as unclear areas in the printed image.

In the short inking device disclosed in DE 32 32 780 A1, one or two inking rollers having the same diameter as the printing form cylinder are used. The advantage of this inking device is that in such a printing device, the ink deposit cannot be turned by the rollers. In addition to these advantages, this known inking device has also been found to be able to supply dampening water in a simple manner and to avoid contamination of the printing ink even when using papers that tend to clump. . Furthermore, for this purpose, cleaning blades have been proposed which serve to remove the ink film causing the stain. However, with this known inking device it is not clear how exactly thin ink films can be produced in the individual zones without having to go through complex adjustment techniques in order to adjust the ink amount zone by zone. It is.

Furthermore, in the inking device disclosed in French Patent No. 1,401,718, no roller is shown, which is the same diameter as the plate cylinder and which works without causing any turning phenomenon. The device does not fit into the range of short inking devices that work without creating a mother-turn phenomenon. Although this known inking device is only capable of forming a thin ink film, no specific solution has been proposed for this purpose. In this case, since the layer thickness of the highly viscous ink is several μm, high requirements are placed on the geometric precision of the members involved in ink transfer. In this case, the difficulty is further increased by the fact that the layer thickness of the ink film has to be adjusted to a value advantageous in terms of printing technology, depending on the viscosity and the dyeing strength. Achieving this geometrical precision may require high production costs. Furthermore, it must be taken into account, in particular, that deformations, which are caused by the large forces when a thin, highly viscous ink film passes through narrow areas that define the layer thickness, are unavoidable.

Recognizing the above-mentioned shortcomings in known inking devices, the object of the invention is to create a uniform, even, thin ink film that is independent of the printing plate of the printing plate and is not affected by contamination. To provide an inking device capable of transferring ink to a plate cylinder without causing any turning phenomenon, thereby obtaining printed matter printed with uniform and even density over the entire surface. That is, to provide an inking device which is capable of transferring an ink film to a printing plate with a uniform layer thickness everywhere over the entire width and length of the printing plate and over the entire printing time.

Means for Solving the Problem In order to solve this problem, the present invention provides that, in an inking device of the type mentioned at the outset, a relatively thick continuous and uniform ink film independent of the ink demand of the printing plate is produced. The dosing unit forming the ink cylinder is assigned to the first inking roller of the inking roller bank, which first inking roller can be driven slower than the speed of the printing press, and the first inking roller is connected to the ink cylinder. A roller bank of a plurality of inking rollers is provided, the first part of which is driven at the speed of the first inking roller and connected to the last part of the roller bank in the direction of ink transfer. is driven at the speed of the printing press, and is located at the end of the ink roller row and rotates at the printing press speed, in front of the ink supply point by the roller row when viewed in the rotational direction of the ink cylinder. Moreover, for ink deposition, a doctor device for removing ink iP turns reversely transferred from the plate cylinder is provided behind the ink transfer point to the roller.

Functions and Effects of the Invention When configured as in the present invention, a relatively thick ink film is first produced, and then this ink film is spread between the first and second parts of the roller row. Due to the speed difference and the division of the ink between the inking rollers, its thickness is reduced, so that a thin ink film corresponding to the requirements of the plate is obtained in the ink cylinder at the end of the roller train, and this thin ink film is transferred to the ink cylinder. Due to the provision of the doctor device, the ink deposits from the ink cylinder are transferred via rollers onto the platen of the forme cylinder without being adversely affected by ink jets.

The inking device according to the invention thus makes it possible to produce a thin ink film of constant thickness in a simple manner by dividing the ink between the inking rollers, in which case the first part of the roller row and the second part of the row of rollers Due to the speed difference between the sections, the number of inking rollers in the roller bank can be reduced. Therefore, using a relatively small number of ink rollers, it is possible to obtain a thin ink film of a constant thickness as described above, without requiring the conventional adjustment techniques.

Embodiments Items 2 to 7 of the patent claims describe advantageous embodiments of the inking device according to the invention. By driving a metering roller of small diameter, which is assigned to a roller bank already rotating more slowly than the printing press speed, at a still smaller rotational speed, a relatively thick, uniform ink film can easily be produced. Also, claim 5
If a doctor device is provided as described in Section 1, the thickness of the ink film can be reduced thereby, and the number of ink rollers can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The offset printing device shown in FIG. 1 is provided for printing a paper web 1 which is guided between two blanket cylinders 2 to obtain an impression. As is well known, both rubber cylinders 2 are one each.
It cooperates with two plate cylinders 3 to obtain the impression transferred to the paper web 1 from the two plate cylinders 3. All cylinders are supported on both sides in the side frames of each printing device.

In the exemplary embodiment shown, each plate cylinder (30) is inked via a roller 5 which has the same diameter as the plate cylinder. Each ink deposit is assigned to each roller 5 an ink layer 6, which ink layer 6 is inked by an inking device 7 and damped by a dampening device 8.

FIG. 2 shows an embodiment of an inking device according to the invention, in which the inking roller 9 is first provided with an inking roller 11 having an annular groove 31 provided at a predetermined distance. The ink fountain 12 supplies a large amount of excess ink film. A small-diameter metering roller 32 is also arranged on the first inking roller 9, and this metering roller 32 is applied to the first inking roller 9 by means of a pressure medium cylinder 33 and a pivot bearing 34. Contact is made under pressure. In this case, the pivot bearing device 34 is pivotably supported on the crossbar D35.

Metering roller 32 viewed in the direction of rotation of the first inking roller 9
Behind the first ink roller 9, a relatively thick ink film is applied to a plurality of ink rollers 13 to 20 arranged one after the other.
The liquid is transferred to the ink layer 6 through the ink layer 6. Due to the large number of gap locations between the individual inking rollers, the thickness of the transferred ink film is reduced. In this case, in the ink roller rows 13 to 20, rubber ink rollers and kneading rollers may be arranged alternately.

A dampening device 8 is provided downstream of the ink roller 19 in the direction of rotation of the ink cylinder 60, and the dampening water film of this dampening device is applied to the thin ink layer already present on the ink layer 6.

The dampening solution and the ink film are then transferred to a roller 5.

When the ink film is separated during this ink transfer operation, a portion of the ink film formed by the printing plate of the printing cylinder 5 is transferred from the roller 5 to the ink layer 6. This transcribed inkino? The turns are removed from the circumferential surface of the ink cylinder 60 by the doctor device 21. This scraped ink 22 then reaches ink 12. In this case, the ink is 12, the new ink and the scraped ink 2.
A partition wall may be provided between the two.

In special cases, further inking rollers 2 may be assigned to the inking layer 6, which roll against the inking roller 16.

As is well known, the dampening device 8 consists of a dipping roller 26 immersed in dampening water 8, a metering roller 27, a swimsuit roller 28, and a kneading roller 29 assigned to the swimsuit roller. ing.

In this embodiment, it is advantageous if the metering roller is driven at a lower speed than the first inking roller 9, since a precise metering of relatively thick ink films is achieved. The first inking roller 9 as well as the dosing roller 32 can also have a rigid circumferential surface, in which case the dosing roller 32 is driven in the opposite direction of rotation to the first inking roller 9. The drive advantageously takes place at a relatively low circumferential speed, which is related to the speed of the printing press. It is advantageous if this circumferential speed is adjustable in order to adjust the thickness of the ink film. Another means of adjusting the ink film thickness is to vary the distance between the metering roller 32 and the first inking roller 9. In this case, this adjustment can take place via the pressure medium cylinder 33.

Furthermore, in the embodiment shown in FIG. 2, another doctoring device 36 is assigned to the inking roller 14, and this doctoring device 36 serves to transfer the ink to the next inking roller 15 when viewed in the direction of rotation of the inking roller 14. It engages with the circumferential surface of the ink roller 14 at the rear. As a result, the ink rollers 14 and 1
5 can be scraped off from the ink tank 14, so the amount of ink supplied to the ink layer 6 is approximately halved. In practice, it is therefore possible to supply the first inking roller 9 with a comparatively thick ink film via the metering roller 32. The ink scraped off by the doctor device 36 is returned to the ink 12 via the guide plate 37.

In the embodiment of FIG. 3, the ink roller 19 is the ink roller 1.
The ink layer 8 is rotated away from the ink layer 8 and is in contact only with the ink layer 6. This ink roller 19 serves to improve the uniformity of the ink. Furthermore, a further mixing roller 38 is assigned to the ink layer 38, which additionally serves to mix the applied dampening water with the ink film.

In this embodiment, the metering roller 32 comprises two supporting rollers 39.
．． 40 against the first ink roller 9;
In this case, both support rollers 39, 40 may be provided with an annular groove 41.

The two supporting rollers 39, 40 are regulated via a bearing 42 and a pressure medium cylinder 43, the lower supporting roller ○ being simultaneously immersed in the ink tank 2 and serving as an inking roller.

In this embodiment, the ink 22 scraped off by the doctor device 21 is collected in a separate ink tank 44,
The ink is supplied from this ink tank 44 to a preparation device 45.

For example, water or dirt is removed from the ink by means of this preparation device 45, and the prepared ink is then supplied to the ink supply 12 again.

In the shortened row row shown in FIG. 4, for example, there is a speed difference between the inking rollers 14 and 15, and a slip occurs between the two rollers. The ink roller 15 is driven by the following ink roller 20 and the ink layer 6 at the circumferential speed of the plate cylinder 3 or the ink layer 5 . The first part of the roller train (ink rollers 9, 13, 14) is driven at a circumferential speed that is reduced relative to the speed of the printing press. The thickness of the ink layer on the ink roller 15 is reduced by the slot knob between the ink rollers 14 and 15, so that the ink film applied to the ink layer 6 is approximately
The thickness will be ttm. In contrast, the first part of the ink roller bank (ink rollers 9, 13, 14) may be supplied with a relatively thick ink film.

The metering row 246 shown in this embodiment of FIG. 4 forms the ink film on the first inking roller 9 and may also be driven at a reduced speed relative to the first inking roller 9. By providing such speed stages in the ink roller row, it is possible to change the ink film from a relatively thick ink film on the first ink roller 9 to a thin ink film as necessary in the ink layer 6 when using a smaller number of ink rollers. The thickness of the ink film can be reduced up to . In this embodiment, therefore, instead of a large number of ink division points, speed differences in a shortened ink roll train are used to reduce the thickness of the ink film.

In order to press the small metering roller 46 against the first inking roller 9, a plurality of supports 49 are provided over the entire length of the metering roller 46, which are pressed with equal pressure against the metering roller 46.

These supports 49 have bearing surfaces for the metering rollers 46, which bearing surfaces are divided over their entire length by a plurality of inclined grooves 50. This ensures lubrication of the sliding of the small metering roller 46 and, moreover, equalizes the ink reservoir 47 in the ink fountain 48.

The ink cartridge 48 is fixed to a grate 51 provided with slits so as to be movable in the longitudinal direction, and a plurality of turning holes 52 are provided below this grate 51, and these turning points are fixed to a grate 51 having slits. The plate section defined via the 52ti adjustment cylinder 53 and thus the support 49 provided thereon
lift up. This configuration allows the small metering roller 46
It is possible to apply the pressure from area to area with equal pressure or, for example in the case of lithography, with different pressures. In this case, the adjusting cylinder 53 and the swiveling lever a2 are fixed to the crosspiece 54, so that a stable support of the support 49 and thus of the small metering roller 49 is guaranteed.

The doctor device shown in FIG. 4 is supported on a tubular body 55, which is pivotably mounted on the side frame 4 via adjustment means (not shown), such as a pneumatic cylinder. Two clamping rails 56 are provided inside the tubular body 55, and a doctor blade 57 is clamped between the two clamping rails via two support plates 58. In this case, the support grate 58 passes through a slit 59 provided in the longitudinal direction of the tubular body 55 together with the doctor blade 57 . Therefore, by rotating the tubular body 55, the distance between the doctor blade 57 and the ink cylinder 6 together with the supporting solates 58 is adjusted, and as a result, the elastic doctor blade 57 is moved from the ink remaining on the circumferential surface of the ink cylinder. Scrape off the turns from the ink cylinder 6. The ink scraped off here falls directly into the ink fountain 48. This is a lower support grade 5 near Dorata Blade 5F0.
This is achieved by a drip strip 60 provided at 8. For example, when the doctor blade 57 is to be reground, in such a configuration, the doctor blade 5 is held on the clamping rail 56.
7 can be pulled out of the tubular body 55 in the axial direction, without requiring any major disassembly work. After grinding the doctor blade 57, the doctor device can be reassembled by reversing the procedure. Due to the advantageous design of the doctor device, contamination with ink is also significantly avoided in this case. This also applies to the adjustment means for the metering roller 46 which are provided outside the fountain 48.

For interrupting the ink supply and for cleaning the inking device, the ink fountain 48 together with the metering roller 46 and the support 49 can be shifted outwards by a predetermined value (see dash-dot line). When a cleaning liquid is applied to a predetermined location of the inking device after the ink cartridge 48 is drawn out, the ink dissolved by the cleaning liquid is scraped off by the doctor blade 57 and drips into the saucer 61. The collection plate 62 of this tray 61 extends close to the ink cylinder 60. After cleaning the inking unit, the ink fountain 48 need only be moved back into its working position, after which the printing press can start working.

FIG. 5 shows the support 49 provided in the small metering row 246 and the area and the inclined groove 5o provided in the support. The metering roller 46 is rotatably supported by the ink 48 via a bearing 63 and is driven via a spur gear 64 at a small circumferential speed.

The embodiment shown in FIG. 6 differs from the embodiments already described in the following points. That is, in the embodiment shown in FIG. 6, the roller row includes two ink rollers 20.
It doesn't have 65L. In this case, the first ink roller 6
5 is immersed in the ink fountain 12 and takes out the ink.

A small metering roller 66 forms a relatively thick ink film on this first inking roller 65 , and the metering roller 66 applies the first ink by adjusting means 67 via a tongue 68 fixed to a rail 69 . It is pressed against the roller 65. In this embodiment, the ink rollers of the ink roller bank, including the last ink roller 2o, are driven at a significantly lower speed than the ink cylinder 6, so that the relatively thick ink film in the ink roller bank is approximately l:10. The large speed difference causes it to break up into thin ink films. This thin ink film is supplied from the ink cylinder 6 via the rollers 5 to the plate of the plate cylinder 3 in the manner described above. A rider roller 70 may be provided on the first ink roller 65 to make the relatively thick ink film uniform.

The embodiment shown in FIG. 7 differs from the embodiment shown in FIG. 6 in the following points. That is, in the embodiment shown in FIG. 7, inking rollers 72, 73 are arranged on the first inking roller 71, and both inking rollers cooperate with the inking roller 20 to transfer ink to the ink cylinder 6. In this case as well, the ink roller rows 71, 72, 73, 20 rotate slowly by a predetermined value compared to the ink cylinder 6, but the ink roller 20
and the ink cylinder 6 need not be as large as in the embodiment of FIG. This is because, in this exemplary embodiment, the remaining ink on the inking roller 73 is scraped off by the doctor device 36, so that the ink film transferred to the inking roller 2o is already reduced to approximately half its thickness. Therefore, the difference in circumferential speed should also be about 1.5.

In this embodiment, the ink dispenser roller 74 holds 12 inks.
The ink is supplied to a small metering roller 66. In this case, the ink dispenser roller 74 has an annular groove 75.
is provided.

The ink is metered using the small metering roller 66 as described above.
and the first i/kilo-rahu 1.

FIG. 8 shows an ink metering device of a somewhat different type from the embodiment shown in FIG. It is arranged in the center between the output roller 74 and the output roller 74 . In this embodiment, the ink ductor roller 74 and the metering roller 66 are driven at a reduced speed relative to the first inking roller 71. In addition, the ink ductor roller 74 and the metering roller 66 can be adjusted with respect to the first ink roller 71 via an adjusting screw 76 . For this purpose, the shaft neck 7 of the ink fountain roller 74
7 is supported by a sliding bearing 78, and this sliding bearing 78
The machine itself is fixed to the side frame 4 of the printing press.

In order to influence the distribution of ink over the length of the first inking roller 71, the metering roller 66 is mounted on a sliding bearing 79.
can be shifted via the adjusting screw 8o, so that a large amount of ink is transferred to the roller end. In this case, the first ink roller 71 may have an elastic circumferential surface and the metering roller 66 may have a rigid curved surface.

It can be seen from the different embodiments described above that the invention can be used in any printing device configuration while retaining the advantages mentioned above, in which case the thickness of the ink film can be adjusted to the required thickness on the plate cylinder. A gradual reduction in thickness is always guaranteed, and this does not require any expensive and complicated adjustment techniques.
