Definitions

  • the invention relates to a rotary printing press with a drive for a cylinder which has independently rotatable, drivable cylinder segments.
  • the DE 44 26 987 A1 shows a drive of folding cylinders of a folder of a rotary printing press, wherein in detail a knife cylinder, a NOTEur folding blade, a jaw cylinder and a gripper cylinder via spur gears are in driving connection and are mechanically driven in series.
  • the NOTEur folding blade cylinder and the jaw cylinder are each designed as a so-called two-piece cylinder, ie, they consist of nested, mutually rotatable cylinder segments.
  • the cylinder segments carry systems, such as folding blades or jaws, which are adjustable in an adjustment of the folder in their circumferential distance to adjacent systems. In this way, for example, the prefold adjustable or a format adjustment executable.
  • the adjustment of the cylinder segments by means of planetary gears.
  • the drive contains except the cylinder gears of the cylinder no further gear, whereby the backlash minimized.
  • Correspondingly accurate operations can be performed with the cylinder, for example, with a folding cylinder exactly folds be performed, the prefolding be set and realized accurately. Folding differences are decisively minimized by the angular position of the functional groups, which can be maintained with high accuracy.
  • the proposed drive results in a reduction of series connected, never ideal rotating masses, never ideal mechanical contact points and the associated interference. Due to the reduction of the masses connected in series, the mechanical contact points and the associated flexibility, an increase in the torsional rigidity in the individual functional groups is achieved. There is a decoupling of disturbances, for example by knife and Falzelle, in the individual functional groups. There is an increase in the Störsteiftechnik / reduction in susceptibility to interference by, for example, knife and Falzelle due to the stiffer connection of the engine with the location of the fault and thus a sharper control.
  • the lower complexity and higher stiffness of the isolated functional groups makes it possible to use periodic and adaptive compensation controllers with which an increase in the interference stiffness / reduction of the susceptibility to interference is feasible. Overall, this makes it possible to increase the accuracy of the synchronization between the functional groups and thus, for example, a significant increase in the cutting and folding accuracy when used on folding cylinders.
  • the drive makes the evaluation of motor / drive controller variables, such as motor current and control differences, possible, with which, for example, the mechanical wear of cutting and folding blades can be assessed.
  • the drive uses structurally simple elements and is thus inexpensive to produce.
  • FIG. 1 shows a folder in a stretched arrangement of its cylinders and drive wheels.
  • the folder includes a knife cylinder 1, a folding cylinder 2, a jaw cylinder 3 and a rapier folding blade cylinder 4.
  • the cylinders are mounted in side walls 5, 6.
  • the knife cylinder 1 is equipped, for example with two opposite cutting blades 7 ( Fig. 2 ).
  • a spur gear 8 is fixed, in which an electric motor 9 engages with its pinion 10.
  • the folding cylinder 2 consists of a retaining elements 11 supporting cylinder segment 12 and a folding blade 13 supporting another cylinder segment 14.
  • the cylinder segments 12, 14 are for example made in three parts, ie, they carry three offset by 120 ° holding elements 11 and folding blade 13. Die Zylindersegmente 12, 14 are rotated against each other. They are also independently drivable and therefore each with its own electric motor 9, 15 in drive connection. This is on each cylinder segment 12, 14, a spur gear 16, 17 attached.
  • the spur gear 16 of the cylinder segment 12 is in engagement with the spur gear 8 and is thus indirectly driven via the latter by the electric motor 9, which engages with its pinion 10 in the spur gear 8.
  • the electric motor 9 could engage with its pinion 10 in the spur gear 16.
  • In the spur gear 17 of the further cylinder segment 14 of the electric motor 15 engages with its pinion 18 a.
  • the folding cylinder 2 of the jaw cylinder 3 works together.
  • the latter in turn consists of two cylinder segments 19, 20, wherein the cylinder segment 19 jaws 21 and the other cylinder segment 20 jaws 22 carries.
  • the cylinder segments 19, 20 are each designed in three parts, for example, so that they each carry three jaw folding systems 21, 22.
  • the cylinder segments 19, 20 are mutually rotatable and independently drivable.
  • a spur gear 23, 24 is attached to each cylinder segment 19, 20.
  • the spur gear 23 of the cylinder segment 19 is engaged with the spur gear 17 of the further cylinder segment 14, whereby the cylinder segment 19 is indirectly in driving connection with the electric motor 15 via the spur gear 17.
  • the pinion 18 of the electric motor 15 could engage directly in the spur gear 23.
  • the spur gear 24 of the further cylinder segment 20 engages an electric motor 25 with its pinion 26 a.
  • the folding cylinder 2 is fed via unspecified draw rollers and perforating a strand 33, which may already be folded along, for example by means of a folder.
  • a strand 33 In conjunction with the folding cylinder 2 cut the cutting blade 7 of the knife cylinder 2 the strand 33 in products 34 which are received by the holding elements 11 of the folding cylinder, for example, punctures.
  • the knife cylinder 1 and the folding cylinder 2 are the knife cylinder 1 and the support members 11 supporting cylinder segment 12 via their spur gears 8, 16 in drive connection and are driven by the electric motor 9.
  • the cylinder segment 14 is synchronously driven by means of the electric motor 15, which engages with its pinion 18 in the spur gear 17 of the further cylinder segment 14.
  • the electric motors 9 and 15 as well as the electric motor 25 are asynchronous motors, which are driven in position-controlled manner via an electronic, so-called virtual guide shaft.
  • Such drives are familiar to the expert and for example in the DE 43 22 744 A1 described. Synchronous motors or other high-precision motors can also be used.
  • the product 34 located on the folding cylinder is transferred during the further rotation of the folding cylinder 2 by the folding blade 13 in a folding flap 21 of the jaw cylinder 3, wherein a transverse fold is generated.
  • the interaction of the folding blade 13 with the jaw 21 is given by the drive connection of the said elements bearing cylinder segments 14 and 19 via the spur gears 17 and 23.
  • the product is transferred to the gripper 27 of the cylinder segment 28 of the rapier folding 4. Again, the interaction of the jaw 22 and the gripper 27 on the spur gears 24 and 31 of the said elements 21, 27 bearing cylinder segments 19, 28 is ensured.
  • the product 34 located on the rapier folding blade 4 is transferred by the folding blades 29 into the jaws 22 of the jaw cylinder 3, forming a second transverse fold.
  • the interaction of said folding blade 29 and the folding flap 22 is ensured by the drive connection of the cylinder segments 30, 20 carrying them via the spur wheels 32, 24 connected thereto.
  • the drive of these cylinder segments 30, 20 is synchronous with the other cylinder segment 28, 19 of the rapier folding blade 4 and the jaw cylinder 3 by means of the electric motor 25.
  • the now twice transverse folded product 34 is finally removed from the jaw cylinder 3.
  • the folding blade 13 relative to the support members 11 is to be rotated. This is done by a temporary forward or lagging operation of the electric motor 15 relative to the electric motor 9, whereby the angular position of the electric motor 15 is changed to the electric motor 9. Accordingly, the cylinder segment 14 is rotated with its folding blades 13 relative to the cylinder segment 12 with the holding elements 11.
  • the position of the second transverse fold produced by the folding blade 29 is also variable with respect to the first transverse fold.
  • the electric motor 25 is temporarily operated in a forward or backward manner, depending on whether the second transverse fold is to be generated closer to the first transverse fold or further away from it. It is so the angular position of the folding blade 29 supporting cylinder segment 30 relative to the driven by the electric motor 15, the jaw 21 bearing cylinder segment 19 changed.
  • the angular positions to be set on the electric motors 15 and 25 for the desired positioning of the cylinder segment 14 with the folding blade 13 or the cylinder segment 30 with the folding blade 29 as well as positions of the electric motor 9 are stored in a computing and storage unit 35. This is connected to the input of the motor control of the electric motors 9, 15, 25 in connection. For an adjustment of said elements, the desired angular positions of the computing and storage unit 35 are retrieved and the motor control of the electric motors 9, 15, 25 specified. Instead, it is also possible to manually enter the desired adjustments on the control station of the printing press.
  • Such stops are also present on the jaw cylinder 3 and the rapier folding blade 4 in order to limit the mutual rotatability of the cylinder segments 19, 20 and 28, 30.
  • limit switches 38, 39 can be used instead of or in conjunction with the mechanical stops 36, 37 and hardware limit switches, such as limit switches 38, 39.
  • limit switches 38, 39 are in Fig. 3 in brackets with given.
  • the position control of the electric motors 9, 15, 25 contains limit setpoints for their mutual angular offset, which limits the mutual rotatability of the cylinder segments 12, 14, 19, 20, 28, 30.
  • the jaw cylinder 3 consists of two cylinder segments 19, 20.
  • the gripper folding blade 4 can be omitted if only one transverse fold is to be generated.
  • the subdivision of the jaw cylinder 3 in cylinder segments can be omitted and this cylinder consist of only one body, which then also the electric motor 25 is unnecessary.
