Definitions
- the present invention relates to a rotary printing press rubber-rubber printing units arranged vertically one above the other.
- the height of the printing tower which is kept low due to this H construction, has an effect disadvantageous on the accessibility of the components of the printing tower, in particular the cylinders and rollers. Between the H printing units arranged one above the other only a low maintenance tunnel remains, which is from Operating personnel can only be walked on in a bent posture. The same applies especially to the accessibility of the bottom and top printing units such Printing tower.
- the two rubber cylinder pivotable from one another such that between the cylinders of such a printing unit an accessible space is formed by an operator be conveniently committed, for example for the purpose of roller replacement can.
- each second of the rubber-rubber printing units arranged one above the other has swiveling rubber cylinders.
- a particularly convenient access to all printing units of a printing tower is due to the pivoting of the rubber cylinders of all Printing units of a printing tower created.
- the rubber-rubber printing units are preferably a printing tower either all arranged as " ⁇ " -shaped or "V" -shaped cylinder bridges. This makes the pressure tower particularly low. Another advantage is that justifies that the ink and fountain solution are the same for each printing unit Direction, either counter or by gravity, to the one in question Rubber cylinder is promoted. This improves the uniformity of the color structure of the printing units with each other.
- Figure 1 shows a printing tower 20 of a rotary printing press, the four one above the other arranged arranged similar printing units 11, 12, 13 and 14.
- Each these printing units 11-14 comprise a pair of impression and impression cylinders, namely blanket cylinders 2 and 4, the respectively associated plate cylinder 3rd and 5 and the plate cylinders 3 and 5 each subordinate color and Dampening units 6 and 7, of which only two are shown in the drawing.
- the blanket cylinders 2 and 4 of the four printing units 11-14 arranged one above the other can be swung apart. Are representative of all printing units only the rubber cylinders 2 and 4 of the lowest printing unit 11 in their shown pivoted position.
- the two rubber cylinders 2 and 4 each about the axes of rotation of their assigned plate cylinders 3 and 5 pivoted from one another into the positions designated by 2 'and 4' in FIG approximately vertically above their respective plate cylinders 3 and 4. After the Swinging is between the two rubber cylinders 2 'and 4' and assigned plate cylinders 3 and 5 and their subordinate color and Dampening units 6 and 7 opened a space 23, the maintenance and Adjustment work for the staff is easily accessible.
- the gap 23 is in Figure 1 indicated as a rectangle and extends from the bottom 21 of the printing tower 20 to the second printing unit arranged above the lowermost printing unit 11 12. Its width corresponds approximately to the clear distance between the two Plate cylinders 3 and 5.
- the total now for maintenance and adjustment work Available positions or rooms are also indicated in Figure 1.
- As in Conventional design also has the staff from the outside, for example on Floor 21 or a vertically movable maintenance platform 31 of the printing tower 20 standing, access to the printing units.
- the same now stands for other Freedom of movement of the space 23 formed according to the invention is available.
- the cylinders and rollers of the printing units 11 forming the printing tower 20 14 form all " ⁇ " - or "V" -shaped cylinder bridges. For one, it is through this uniform alignment of the cylinders and rollers the largest possible, namely highest possible, space 23 is formed and on the other hand, the color and Dampening solution flow to all rubber cylinders 2 and 4 always in the same direction. In principle, both advantages could also be achieved with printing units 11-14 which Form "V" -shaped cylinder bridges. In this case, the color transport would be with the support of gravity instead of against it, as in the exemplary embodiment, respectively.
- Gap 23 is sufficient if only every second of the printing units 11 - 14, preferably the lowest printing unit 11 and the next but one printing unit 13, has swiveling rubber cylinders 2 and 4.
- FIGS swiveling rubber cylinders 2 and 4 ( Figure 2) and a pressure tower 20 after State of the art (FIG. 3) with four printing units arranged one above the other are arranged to form H-shaped cylinder bridges.
- both printing towers 20 eight single-color printing units are arranged, two printing units each one Form rubber-rubber printing unit.
- the cylinders and rollers of the printing tower 20 according to Figure 2 too Maintenance and adjustment work more easily accessible. Under and over the in 3 remain in a conventional manner arranged in an H-shape only very low maintenance tunnel T free.
- This conventional maintenance tunnel T are lying down or at most in a stooped posture, which makes maintenance and Adjustment work can be made considerably more difficult.
- With the printing material web B drawn in are such works because of the printing material web crossing the maintenance tunnel T. impossible.
- the entire space 23 available by pivoting the rubber cylinders 2 and 4 can be kept almost entirely free.
- the drawn-in printing material web B 1 is guided near one side of the intermediate space 23, ie at a short distance from one of the plate cylinders 4 or 5 and the pivoted-off rubber cylinder 2 or 3.
- the web deflecting rollers are to be arranged in the region of the intermediate space 23 formed in this way on one of the sides of this intermediate space 23, as can be seen in FIG. 4 using the example of two times 1 + 1 color production per double printing unit.
- the two printing towers 20, in accordance with FIGS. 2 and 3, are again placed next to one another for comparison purposes.
- the printing towers 20 are each configured for two times 1 + 1 color production per double printing unit.
- the accessibility of at least one of the two printing units, each forming a printing unit is ensured only via the very uncomfortable low maintenance tunnels T for each conceivable guidance of the printing material webs B 1 - B 4 .
- work can only be carried out from the outside in a stooped posture on the respective lower printing units 11 and 13 of the two H-shaped cylinder bridges.
- each printing unit The free passage to the left and right of each printing unit is greatly reduced by the printing material web that runs in and out at the side.
- the top pair of rubber cylinders of each H-cylinder bridge are not accessible when the web is retracted, for example for changing plates or cleaning a rubber blanket.
- a corresponding effort is to be made by providing appropriate web shifting means, as indicated at 51 and 52, or other cylinder release devices.
- the printing material web is guided with the rubber cylinders 2 and 4 pivoted away as close as possible to one of the pivoted rubber cylinders, ie close to the sides of the intermediate space 23.
- This is achieved in the exemplary embodiment by a corresponding arrangement of the web deflecting rollers which are arranged in front of the web inlet and behind the web outlet in or out of the printing units, the rubber cylinders 2 and 4 of which form the intermediate space 23 between them in the pivoted-down position 2 'and 4'.
- the two web deflection rollers 41 and 42 are indicated in FIG.
