Definitions

  • the invention relates to a folding cylinder according to the preamble of claim 1.
  • a folding cylinder with an adjustable circumference is known from DE 295 02 957.9 U1, the shaft of the folding cylinder being equipped with a coaxial bore in which a drivable adjusting spindle is arranged, the rotational movement of which is mechanically transmitted to axially parallel spindles with the circumference of the Folding cylinder is coupled with varying radially adjustable support elements for the folding products.
  • the invention has for its object to provide a folding cylinder according to the preamble of claim 1, which ensures an adjustment of the mechanisms while running the machine with inexpensive, simple means.
  • a traction device enables simple transfer of the adjustment movement from the coaxial adjusting spindle to the spindle connected to the adjustable mechanisms in the tightest of spaces.
  • the subclaims contain favorable embodiments of the solution principle, in particular with respect to the traction means, the adjustment of the mechanisms in the form of folding flaps or the circumference of the folding cylinder, the support elements, the arrangement of the spindle connected to the mechanisms and the axial adjustment of the adjusting spindle.
  • Fig. 1 shows a folding cylinder 1 whose circumference by means of radially adjustable support elements 2; 3 is changeable for the folding products, not shown.
  • an adjusting spindle 6 is axially adjustable in a coaxial bore 4 of the shaft 5 of the folding cylinder 1 by means of an actuating drive 7 which can be actuated outside the machine casing.
  • a bolt 9 fastened the ends of a traction means in the form of a chain 11, the two converging dreams 12; 13 each by a in a radial opening 14; 15 of the bore 4 on an eccentric pin 16; 17 mounted deflection plate 18; 19 90 ° deflected with the interposition of a 90 ° angular displacement link to a toothed drive pulley 22, which is fastened on a spindle 21 mounted in an axially parallel manner to the shaft 4 in the spindle 21 mounted to this fixed cylinder body 20 and looped around it.
  • the spindle 21 has an eccentric pin 23 at its ends; 24, which is arranged in a disk 25; 26 engage positively in their direction of rotation.
  • the disks 25; 26 are provided with oblique holes 27; 28 equipped (FIG. 2), in each of which a pin 29 to 32 of a radially displaceably guided axially parallel in the cylinder body 20, along the cylinder body 20 several times with support elements 2; 3 equipped crossbeam 33; 34 engages (Fig. 1).
  • a bearing housing 35 is fastened to the end of the adjusting spindle 6 outside the bore 4 and is secured against rotation with the aid of a guide pin 37 which engages axially parallel to the adjusting spindle 6 in a bore 36 of the shaft 5 relative to the shaft 5.
  • a guide pin 38 is axially fixed, to which a connecting piece 39 is articulated, one of which is axially parallel to the adjusting spindle 6 in the frame 40; 40 'mounted threaded spindle 41 has threaded bore.
  • the threaded spindle also engages with another thread of opposite pitch, i. H. with a right-hand or left-hand thread into a corresponding threaded bore of a guide piece 42 fastened to the frame 40.
  • the threaded spindle 41 can be fixed against rotation by means of a clamping device 43 and is equipped with an operating element 44.
  • FIG. 3 shows a cylinder part 47, which is rotatably arranged on the shaft 5 'and each has folding jaws of the same type as fixed folding jaws 45 or movable counter-folding jaws 46; 48 existing folding cylinders 1 ', the fixed folding flaps 45 being fastened to the inside solid cylinder part 47 and the counter folding flaps 46 being in axial openings 49; 50 of the latter by means of trusses 51; 52 connected disks 53; 54 are stored.
  • the means of FIGS. 1 and 2 are applied analogously, the spindle 55 with an eccentric portion 56 in a recess 57 of the disk 54 being positively arranged on the one hand in its direction of rotation and on the other hand with radial play and with two central sections 58 arranged on both sides of the eccentric section 56; 59 is mounted with the section 58 in the other cylinder part 47 and the section 59 in the rotational direction of the folding cylinder 1 'positively penetrates a recess 60 of a driver 61 fastened on the shaft 5' and carries the drive pulley 22 'on the outside at the end.
  • FIGS. 4 and 5 show a folding cylinder 1 ′′ designed analogously to FIG. 3, the cylinder part 47 ′ carrying the fixed folding flaps 45 ′ differing from the cylinder part 48 ′ carrying the movable counter-folding flaps 46 ′ 3, with the aid of a spindle 62 arranged in a plane perpendicular to the adjusting spindle 6 ′′, which is mounted twice in a fork 63 firmly connected to the driver 61 ′, each with radial play, and between the two bearing points the drive disk 64 carries, due to the arrangement rotated by 90 ° with respect to FIGS. 1 to 3, the angular displacement links in the chain 65 are omitted and the two deflection disks 66; 67 are arranged in a continuous recess 68 that runs axially parallel to the adjusting spindle 6 ′′.
  • the spindle 62 engages through threads arranged at its ends, each with opposite, equal pitch, in a threaded bore of a bolt 69 rotatably mounted in the respective cylinder part 47 'or 48'; 70, the bolt 69 for the inner cylinder part 47 ', the outer disk 53' of the other cylinder part 48 'in a recess under which the mutual rotation of the cylinder parts 47'; 48 'permitting radial play.
  • the traction means with the associated drive means can be arranged both inside and on the end face of the folding cylinder depending on the particular design of the folding cylinder.
