Definitions
- the invention relates to a switching device for the blanket cylinders of a web-fed offset printing press, in which four printing unit cylinders are arranged one above the other, essentially on an inclined line with respect to an approximately horizontally running printing carrier web, the printing carrier web being able to be carried out between the two inner printing cylinders designed as blanket cylinders is.
- the object of the present invention is to separate the two central cylinders from one another in a printing unit of the type described at the outset by means of a single adjusting device, without the outer cylinders having to be pivoted beforehand.
- the illustrated printing units 1 according to FIGS. 1 to 3 can each be arranged several times in succession for the application of multi-color prints on both sides of a printing material web T, such printing units each comprising four cylinders 2, 3, 4, 5 lying one behind the other, which approximately on a common center line G are positioned.
- the cylinders 2, 3, 4, 5 are supported against each other, whereby the risk of deflection and thus an unfavorable effect on the printing result is avoided or reduced.
- the printed material web T to be printed is guided approximately horizontally through the two middle cylinders 3, 4, the so-called blanket cylinders, so that it can be printed on both sides.
- the straight line G is more or less inclined, that is to say it is not at right angles to the direction of movement of the printed material web T.
- each printing unit side wall 1 of the printing units shown according to FIGS. 1 to 3 for a web-fed rotary offset machine bores A, B are provided for the two middle cylinders 3, 4 for mounting the cylinders 3, 4.
- the cylinder pins 6, 7 of the blanket cylinders 3, 4 are each in two eccentric bushes, namely an eccentrically drilled outer sleeve 8 and an eccentrically drilled inner sleeve 9 for the cylinder pin 6 and an eccentrically drilled outer sleeve 10 and an eccentrically drilled inner sleeve 11 for the cylinder pin 7 , positioned.
- Each of the eccentric bushes 8 to 11 is assigned an adjusting lever 12, 13, 14, 15.
- the adjusting levers 12, 14 for the inner eccentric bushes 9, 11 are connected to a pull rod 17 and the adjusting levers 13, 15 for the outer eccentric bushes 8, 10 are connected to a pull rod 16.
- an adjusting device 20, 21 is connected to a pair of eccentric bushes, for example the lower one, by means of which the eccentric bushes 10, 11 can be rotated via tie rods 18, 19.
- the movement of the tie rods 18, 19 and thus the rotation the eccentric bushes 10, 11 takes place with the aid of an adjusting device 20, 21 which comprises a pivoting lever 20 which is arranged on an adjusting spindle 21.
- the adjusting spindle 21 can be rotated by motor or by hand.
- the adjusting spindle 21 is rotated clockwise to position 21 ', the adjusting levers 12 to 15 and the tie rods 16 to 19 assume the position 12', 13 ', 14', 15 ', 18', 19 'shown in dashed lines, so that a corresponding rotation of the eccentric bushes 8 to 11 takes place.
- the adjusting levers 12 to 15 and the tie rods 16 to 19 are dimensioned such that all eccentric bushes 8 to 11 are rotated by the same amount, that is to say by the same degree of angle, when the adjusting spindle 21 is rotated. This ensures that the inner eccentric bushing 9 is turned by the same angular amount, but in the opposite direction as the outer eccentric bushing 8, when starting and stopping. The same applies to the inner eccentric bushing 11 and the outer eccentric bushing 10.
- the pull rods 18, 19 could also act directly on the pull rods 16, 17.
- the contact force between the outer cylinder, for example 2, and the associated inner cylinder, for example 3, can also be set individually to the desired dimension or to the desired contact pressure.
- the reference numerals 22, 23 indicate the center of the cylinders 3, 4 in the switched-off state and the reference symbols 24, 25 indicate the center of the cylinders in the switched-on state.
- the reference numerals 24, 25 indicate the center of the bore and the center of the inner eccentric bushes 9, 11.
- the reference numerals 26, 27 and 26 ', 27' and 26 ", 27" refer to the center of the bores of the outer eccentric bushes 8, 10.
- the reference numerals 22, 27 shown in FIG. 1 indicate that the mentioned centers of the upper inner cylinder 3 are always on the left side of the common straight line G and. the mentioned centers of the lower inner cylinder 4 come to lie on the right side of the common straight line G. 2 and 3, the reference numerals 22, 27 'and 22, 27 "and thus the center points of the cylinders 3 and 4 are either on the right side (FIG. 2) or on the left side (FIG. 3 ) of the straight line G. This ensures that when the inner cylinders 3, 4 move in the direction of the arrows P (positioning movement), the cylinders 3, 4 can be set against one another with the required force. 25 are as close as possible to the common line G.
- FIGS. 2, 3 it is advantageous to move the outer cylinders 2 laterally (in each case slightly with respect to the straight line G) (FIG. 2 to the left, FIG. 3 to the right). This facilitates the outward movement of the inner cylinders 3, 4 to the right (FIG. 2) or to the left (FIG. 3) and the respective adjustment process.
- the magnitude of the contact force between the inner cylinders 3, 4 and between these and the respective outer cylinders 2, 5 is determined by threaded bushings 28, which are located in the tie rods 16, 17, 18 and 19 and have threaded bushes 28 through which the tie rods 16 , 17, 18, 19 can be extended or shortened.
