Definitions

  • the invention relates to cylinders for processing flat material according to the preamble of claim 1 or 2.
  • Cylinders of this type are used in particular in the folding apparatus of a printing press, where the movable tools can be, for example, puncture strips, grippers, folding knives, folding jaws or the like and the cylinders are accordingly referred to as puncturing, gripper, folding or folding jaw cylinders.
  • DE 101 56 194 A1 proposes to reduce the frictional wear on the cover disk sensing roller by providing two control arms instead of a control arm with two sensing rollers, one of which carries the cam disk sensing roller and the other the cover disk sensing roller.
  • the abrupt acceleration of the cover disk feeler roller is avoided here by keeping it in constant contact with the cover disk.
  • the invention has for its object to provide cylinders for the processing of flat material, in which wear is reduced between the cover plate and the associated control device.
  • the advantages which can be achieved with the invention consist in particular in that the wear in the contact area between the cover plate and the control device scanning it is kept low without constant contact between the control device and the cover plate being required for this.
  • a loss of contact between the control device and the cover plate is accepted in the construction, and the Wear is reduced by reducing the relative speed between the rotating cylinder body and the cover plate.
  • the roller for scanning the cover plate can easily be mounted on a common control lever with a roller for scanning the cam disc. Then, however, the role of the cam disc loses contact with the cam disc when the cover disc blocks the work movement, slows down and must be accelerated again.
  • two control levers can be provided, one for each roller, which allow the roller of the cam disks to remain in contact with the cam disk even when the cover disk blocks the working movement.
  • Figure 1 is a partial perspective view of a puncture cylinder.
  • FIG. 2 is an exploded detailed view of the control device with two control levers of a puncture bar of the cylinder from FIG. 1;
  • FIG. 3 shows a detailed view of a simplified control device with a control lever and two rollers mounted thereon;
  • Fig. 7 shows an example of a transmission for coupling the rotations of the cylinder body and cover plate.
  • FIG. 1 shows an end section of a cylinder body 01 with three puncture strips (only two visible in FIG. 1).
  • the cylinder body 01 is shown here as cylinder 01 in the narrow, geometric sense, but it goes without saying that in practice it is possible to deviate from the geometric cylinder shape provided that signatures on the lateral surface of cylinder 01 are conveyed on a circular or circular sector-shaped path become.
  • the lateral surface can be constructed from a plurality of segments that can be adjusted relative to one another.
  • the tools 02 e.g. B.
  • needles 02 of the puncture strips are each at a distance of 120 ° on the lateral surface of Cylinder body 01 arranged rows of holes can be extended in order to impale supplied signatures thereon and to convey them further on the cylinder body 01 to a transfer gap (not shown).
  • the puncture needles 02 In order to deliver the signatures to the transfer gap, the puncture needles 02 must withdraw into the interior of the cylinder 01.
  • the puncture needles 02 are each fixedly connected to a shaft 03 by arms covered by the jacket of the cylinder body 01 in FIG. 1, each of which is pivotally mounted in the two opposite end plates 04 of the cylinder body 01.
  • Axle pins 06 connected to the end plates 04 are rotatably mounted in a side frame (not shown).
  • a cam plate 07 and a cover plate 08 are provided coaxially with the axle journal 06 shown in FIG. 1.
  • the cam plate 07 has essentially the shape of a circular disc concentric to the axis of rotation of the cylinder body 01, in the circumferential section 09, for. B. peripheral surface 09 a peripheral portion 11, z. B. an indentation 11 is formed.
  • the cover plate 08 can be understood as being made up of four congruent 90 ° sectors, each of which has an arcuate section 12 with a large radius, a section 13 with a smaller radius and inclined surfaces 14 which gradually transition between the sections 12; 13 form.
  • Each of the three shafts 03 of the cylinder body 01 carries two control levers 16; 17, which together form a control device for controlling the movement of one of the puncture strips.
  • the control levers 16; 17 shown in Fig. 1 only on one of the shafts 03.
  • the first control lever 16 carries at its free end a roller 18 which rolls on the peripheral surface 09 of the cam plate 07.
  • the second control lever 17 carries a roller 19 which rolls on the peripheral surface of the cover disk 08.
  • the second control lever 17 is fixedly connected to the shaft 03, while the first control lever 16 is rotatable about the shaft 03.
  • the two control levers 16; 17 each carry the other control lever 16; 17 facing side flank a projection 21 or 22.
  • a compression spring 23 which the two projections 21; 22 drives apart (see Fig. 2).
  • a torque acts on the shaft 03, not shown, for. B. accommodated in the cylinder body 01 spring which drives the roller 19 against the peripheral surface of the cover plate 08.
  • the roller 19 does not touch the cover disk 08, since a contact between the projections 21; 22 and the roller 18 of the first control lever 16 rolling simultaneously on the peripheral surface 09 prevent this.
  • the roller 18 is in contact with the cam plate 07 during the entire rotation of the cylinder body 01 and is therefore driven in a uniform manner.
  • FIG. 3 shows, in a perspective view analogous to FIG. 2, a simplified control device in which a single control lever 17 'attached to the shaft 03 has two rollers 18'; 19 'for rolling on the cam plate 07 or the cover plate 08.
  • the control lever 17 “only pivots radially inward when both rollers 18 '; 19' simultaneously pass the indentation 11 or a section 13 with a small radius.

  • a section 12 with a large radius of the cover disk 08 supports the roller 19, so that retraction of the puncture needles 02 into the cylinder body 01 and release of a signature held on the puncture needles 02 is prevented, although the roller 18 into the Immersion immersed.
