Definitions

  • the invention relates to a sheet-fed press and a method for driving rotational bodies of the printing press, which rotate in a first mode with different phase angles and in a second mode with the same phase.
  • the printing material and printing image-carrying rotary body (printing cylinder, transfer drums, blanket cylinder, plate cylinder ...) of conventional printing presses are driven by a all aggregates (printing and coating units) connecting gear train (drive wheel train).
  • the angular positions of the rotating bodies are fixed to one another.
  • discontinuous movements eg Greifer horrgetriebe, Kanalüberroll Institute on sheetfed presses
  • vibration-inducing forces not at all aggregates simultaneously in the drive wheel but temporally distributed, for example, the printing units are not operated with the same angular position (phase), but by a certain angle of rotation offset from each other.
  • the phase angle characterizes the rotational angular position of a characteristic reference point on the circumferential contour of a single large rotational body, for example, the rotational angular position of the cylinder channel of a plate cylinder of a sheet-fed offset printing press, at a certain time.
  • a rotational angle offset of 120 ° is selected between adjacent printing units, so that every third printing unit has the same phase positions of the rotational bodies arranged therein. This means that the same pressure events occur simultaneously in every third printing unit.
  • this rotation angle offset and thus the number of synchronous printing units on the choice of the step angle ⁇ (angle between the straight line connecting the axis pressure cylinder - axis transfer cylinder and the horizontal) and in dependence on the diameter ratios of the contacting cylinder or drums be determined.
  • the rotational angular offset is 180 °, e.g. the printing cylinders in adjacent printing units are rotated by 180 ° with respect to one another, or the same pressure events occur simultaneously in every second printing unit.
  • auxiliary processes such as a plate change on all plate cylinders of the printing units a rotary printing press
  • the press has to move in succession and in groups (in each case the rotational bodies with the same phase position) with all the rotational bodies involved, the rotational angle position required for the respective auxiliary process. For example, if a sheet-fed offset printing press has 9 printing units and the phase positions of adjacent printing units are offset by 120 °, a plate change first in the works 1,4,7, then in the works 2,5,8 and finally in the works 3,6 , 9 take place simultaneously.
  • a disadvantage of this solution is the high cost of equipping all printing units with individual drives, which include motors, drive controllers, rotation angle position sensor and additional electrical connections.
  • the invention is therefore based on the object to reduce the cost of the individual drives, without reducing the time-saving potential of individual drives in the implementation of auxiliary processes.
  • the object is achieved by a sheet-fed printing machine having the features of the first claim or a method having the features of the fifth claim.
  • the basic idea of the proposed solution is to equip the rotating bodies involved in the auxiliary process as a function of their phase position with individual drives (partial individual drive).
  • the costs for the individual drives can be saved at the reference phase rotational bodies.
  • the rotary bodies with the first phase position are rotated together by the existing drive wheel train of the printing press in the required rotational angle position for the respective auxiliary process, while the other rotating bodies are simultaneously rotated by the individual drives in this rotational angular position.
  • the invention has the advantage that the same time savings with a reduced number of individual drives as with complete equipment with individual drives.
  • the largest cost saving effect for the single drive configuration occurs when the group of reference phase rotational bodies driven by the drive wheel train forms the group with the highest number of rotational bodies.
  • the sheet-fed offset printing press consists of 4 printing units DW1... 4, whereby only the double-sized printing cylinders and the simply large blanket cylinders GZ1..4 and plate cylinders PZ1..4 are shown by the printing units. All four printing units DW1 ... 4 are via a drive wheel ARZ, by the meshing drive gears of the individual cylinders DZ1..4, GZ1 ... 4, PZ1 ... 4 in the printing units DW1 ... 4 and the Transfer drums ÜT1 ... 3 between the printing units DW1 ... 4 is formed, driven.
  • the drive torque for the drive wheel train ARZ is provided in known manner by one or more main drives (not shown). Between the printing units DW1 ...
  • phase position difference 120 °, ie the blanket and the plate cylinder GZ1, GZ4, PZ1, PZ4 in the first and fourth printing unit DW1, DW4 are in the same angular position or have the same (first ) Phase position.
  • the color separations in the first and fourth printing DW1, DW4 are simultaneously transferred to the sheet, while the printing sub-images in the second printing DW2 offset by a rotation angle of 120 ° to the first phase of the first printing DW1 and the third printing DW3 240 ° offset to the first Printing unit DW1 is transferred to the sheet.
  • the (further) plate cylinders PZ2, PZ3 in the second and third printing units DW2, DW3 rotate with (further) phase positions offset by 120 ° or by 240 ° with respect to the first or fourth printing unit DW1, DW4.
  • the plate change is an auxiliary process (second mode) in which the plate cylinder PZ1 ... 4 in a certain, in all printing units DW1 ... 4 same Drehwinkeiposition the equipped with Plattenklemmvoruzeen cylinder channel must be rotated so that the removal of the old printing plate and the mounting the new printing plate can be performed without major manual effort.
  • the drive wheel train ARZ When all the plate cylinders PZ1 ... 4 are conventionally driven by the drive wheel train ARZ, the drive wheel train ARZ must first be rotated to the common disk change position of the first and fourth printing units DW1, DW4. After completion of the plate changing process, the drive wheel ARZ is further rotated by 120 ° to the plate change position of the plate cylinder PZ2 in the second printing unit DW2. If the plate change is completed there, the drive wheel ARZ is rotated by a further 120 ° to the plate changing position of the third printing unit DW3.
  • a conventional 4-works press thus requires three cycles for a complete plate change.
  • a 4-plate press equipped with single plate cylinder drives requires only one plate change cycle because all plate cylinders can be rotated independently of the drive gear train and simultaneously into the plate change position, but requires the investment of 4 individual drives.
  • only the (further) plate cylinders PZ2, PZ3 at the second and third printing units DW2, DW3 are each assigned a single drive M1, M2 in the exemplary 4-for-press, which reduces the capital outlay to 50% compared to a press fully equipped with individual drives. can be reduced.
  • the plate cylinders PZ1, PZ4 in the first and fourth printing units DW1, DW4 remain integrated in the drive wheel train ARZ, since they have a matching phase position and do not require separate twistability.
  • the coincident phase position is referred to as a reference or first phase position and the plate cylinder PZ1, PZ4 driven by the drive wheel train ARZ are referred to as first rotation bodies in an analogous manner.
  • the in accordance with the invention with only two single drives M1, M2 equipped press also requires only a disc change cycle. While the (first) plate cylinder PZ1, PZ4 in the first and fourth printing unit DW1, DW4 jointly from Drive wheel ARZ are rotated in the disk change position, the (further) plate cylinder PZ2, PZ3 in the second and third printing DW2, DW3 parallel to it by the associated individual drives M1, M2 of their (further) phase angles in the first phase position of the drive wheel ARZ moving plate cylinder PZ1, PZ4 turned until all plate cylinders PZ1 ... 4 have reached the common plate change position at approximately the same time.
  • the further plate cylinders PZ2, PZ3 can first be rotated in a "catch-up movement" into the first phase position of the plate cylinders PZ1, PZ4 in the first and fourth printing units DW1, DW4 and then rotate all the plate cylinders PZ1 ... 4 with synchronized phase position in the plate changing position. It is also possible that, in order to shorten the plate changing time, the individually driven plate cylinders PZ2, PZ3 are rotated independently of each other and initially independent of the phase position of the plate cylinder PZ1, PZ4 driven by the drive wheel train ARZ on the shortest path to the plate changing position and synchronized in time with the first Plate cylinders PZ1, PZ2 reach the plate change position.
  • the configuration according to the invention of single-drive printing machines is applicable to all rotary bodies that temporarily perform in-phase movements.
  • the coupling of the individual drives M1, M2 for the plate cylinder PZ2, PZ3 with the associated blanket cylinders GZ2, GZ3 for the synchronized implementation of other auxiliary processes, such as washing processes, within the scope of the invention.
  • the synchronization of the individual drives M1, M2 in a known manner via (not shown) rotary encoder on the individually driven bodies of revolution (plate cylinder PZ2, PZ3) and associated rotary encoder, for example, adjacent rotational bodies, which are moved over the drive wheel ARZ (in the example on the blanket cylinders GZ2 , GZ3), wherein the rotation angle signals are processed by drive controllers (not shown) which synchronize with the drive wheel train ARZ.
  • the drive control system is simplified and relieved of synchronization tasks, so that shorter response times and lower vibration tendency can be achieved with longer machines with a higher number of printing units.
