Definitions

  • the invention relates to a drive of a forme cylinder according to the preamble of claim 1.
  • DE 44 30 693 A1 is a printing unit known, wherein the form cylinder is driven and driven off via spur gears on the transfer cylinder.
  • a designed as a rotor pin of the forme cylinder is in the embodiment axially displaceable in the stator for the purpose of adjusting the side register on the forme cylinder in one embodiment. Shaping and transfer cylinders are driven in pairs in one embodiment.
  • the EP 07 22 831 B1 also discloses a drive for a cylinder, wherein the driven by a motor cylinder for the purpose of adjusting the side register is arranged axially displaceable.
  • a coaxially arranged on the pin of the cylinder rotor is axially movable in the stator.
  • DE 196 03 663 A1 is a form cylinder via a gearbox axially and via a helical gear in the circumferential direction relative to the transfer cylinder adjustable.
  • the forme cylinder and the transfer cylinder acting together with it are drivable in parallel by means of a motor.
  • By means of a spigot of the forme cylinder arranged spur gear is drivable on a forme cylinder associated inking unit.
  • the EP 1 000 737 A1 discloses a drive of a cylinder sleeve via a shaft which is axially clamped against a disc. Between the drive motor and sleeve an axial relative movement enabling axial coupling is provided.
  • the DE 197 55 316 C2 discloses the drive of a cylinder from a drive motor via a transmission and via a "balancing clutch". Other cylinders are driven by their own drive motors. The drive motors are offset relative to each other in relation to the respective cylinder.
  • the DE 38 25 307 C1 shows a drive train from a main motor via a helical gear, via a first, axially fixed shaft piece, via a second, axially movable shaft piece, via a third, axially fixed shaft piece on a bevel gear, and from there to a plate cylinder.
  • the axially movable by a drive shaft piece between two eccentrically articulated and elastically deformable spring elements is arranged such that upon axial displacement of the shaft piece torsion occurs.
  • the invention has for its object to provide a drive of an axially movable forme cylinder with circumferentially minimized game.
  • the achievable with the present invention consist in particular in that a drive of axially movable form cylinders is created, with a game in the circumferential direction and a high production cost is minimized.
  • a flexible coupling in the axial direction between the drive motor and form cylinder is arranged. It is in an advantageous embodiment as torsionally stiff but flexible in the axial direction or flexible shaft coupling, z. B. as an expansion or compensating coupling executed. Particularly advantageous is the use of a non-switchable form-locking multi-plate clutch, which is virtually no play in the circumferential direction, in contrast to other positive clutches without major manufacturing effort, and at the same time an axial change in length of the clutch itself, ie an axial movement of the forme cylinder allows.
  • the coupling is positively in the axial direction, but flexible in their length or yielding, z. B. by elastic and reversible deformation, executed.
  • the drive via the coupling is particularly in the case of individual drives on the individually driven cylinders, but in particular on the forme cylinder for the sake of adjustability of the side register, an advantage. If the cylinders of a printing unit are driven individually by a respective drive motor, the circumferential register can be changed by means of changes in the relative angular position of the drive motor, and the side register can be changed relative to one another by means of the axial displacement.
  • the drive motors are arranged coaxially with the cylinder to be driven.
  • the arrangement of the drive motor via the coupling on the forme cylinder of a jointly driven cylinder pair is advantageous.
  • no movement of the drive motor must take place when pressure on and off position of the transfer cylinder, as z. T. in the drive directly on the transfer cylinder is the case
  • Also based on such pivotal movements of the transfer cylinder compromise in the position of the drive motor and the engagement of the gears in the arrangement of the drive motor on the transfer cylinder can be omitted when driving the forme cylinder. The latter can lead to tooth breakage in the other case or due to the play in the drive to reduce the print quality.
  • the drive motor can be arranged directly axially to the forme cylinder or to the driven cylinder.
  • the forme cylinder which is flexible in the axial direction coupling between pin and drive motor can be arranged.
  • the design of the drive motor with a arranged between the rotor and the pin of the cylinder gear, z. B. a planetary gear.
  • an arrangement is advantageous, wherein the pinion of the drive motor does not drive directly on the spur gear of the forme cylinder.
  • a simultaneous adjustment of the circumferential register would take place without additional precautions. Precautions may be, for example, a simultaneous correction over the control, which requires control engineering effort, or an allowable relative movement of the pin to the spur of the forme cylinder, but this requires guides, which are not or only with great effort in the circumferential direction to manufacture play.
  • a flexible coupling in the axial direction can again be used.
  • an inking unit associated with the forme cylinder and, if present, also a dampening unit is driven by the same drive motor. This saves costs and, with the correct gear ratios, ensures synchronization.
  • the inking unit and the transfer cylinder are driven in parallel via the forme cylinder, at least one of the two drive lines requires the use of accessories in the case of gear trains or the use of belt drives that are as free of play as possible.
  • a printing machine in particular a rotary printing press, has on a front side in a side frame, not shown, rotatably mounted pin 04.
  • the pin 04 is the front side via a coupling 06 with a drive motor 07 in operative connection.

  • a transmission 10 in particular a reduction gear 10, such.
  • a planetary gear 10 arranged between the drive motor 07 and clutch 06.
  • This connection between the shaft 08 and the shaft 09 may also have a non-shiftable coupling 11, z. B. via a dog clutch 11, take place.
  • the clutch 11 may, if deviations in the axial direction of the cylinder 01 and the drive motor 07 are to be compensated, also be designed as a curved tooth coupling.
  • the non-switchable coupling 06 is designed such that a length L in the axial direction is variable by an amount of .DELTA.L, preferably in both directions.
  • the coupling 06 is formed such that it has no sliding movement in the axial direction of two circumferentially cooperating stop members relative to each other, but torsionally rigid in the circumferential direction and in the axial direction Direction yielding or reversible elastically deformable.
  • the coupling 06 forming parts are positively connected with each other in the axial and circumferential direction and thus allow a large amount of manufacturing effort in the circumferential direction almost backlash drive and by changing the length L axial movement of the cylinder 01. Since no relative movement between two mutually as a stop transversely takes place to the direction of movement surfaces, the clutch 06 is wear and against Pollution insensitive.

  • the preferred blades of steel ensure in the circumferential direction, ie in the plane of their surface and perpendicular to the axis of rotation of the cylinder 01, a high rigidity, while the annular blades have low strength in the axial direction elastic or resilient properties.
  • Such a coupling 06 is also referred to as a bend-compliant all-metal coupling, as a diaphragm or ring clutch.
  • the coupling 06 is designed torsionally rigid and positive fit due to the rigidity of the slats in the circumferential direction.
  • the alternating attachment of the plate packs 23; 24 on the flange 12; 13 and the middle piece 19 allows despite form fit in the axial direction due to the spring action of the slats in the disk set 23; 24 is a reversible change in the length L of the clutch 06 by an amount ⁇ L dependent on the dimensions of the clutch 06.
  • the force to be expended, ie a spring stiffness in the coupling 06, in the axial direction depends on the Number of slats in the plate pack 23; 24.
  • a torsion spring value for the torsion in the clutch 06 is greater than 10,000 Nm / °, in particular in the range between 10,000 and 20,000 Nm / °.
