Definitions

  • the invention relates to a cross-cutting device adjustable in format length for running webs.
  • a main area of application for such cross-cutting devices is a folding device downstream of a printing press, in which such cross-cutting devices are installed.
  • Such cross-cutting devices are generally known in the form of two cylinders of the same diameter arranged on both sides of the path, one of which, the knife cylinder, carries at least one cutting knife carried by a cutter bar and the other, the counter-cylinder, carries a corresponding number of elastic cutting bars carried by a support beam.
  • the circumferential speeds of the knife and counter cylinders which are equal to one another, must be almost exactly the same as the path speed. If the circumferential speed of the two cylinders were lower, the web would be compressed during the cut, which would make it impossible for the cross-cutting device to work properly. If the circumferential speed of the two cylinders was too high, a kind of tearing effect would occur during the cut, which would not only result in damage to the web, but would also lead to an inaccurate cut.
  • the object of the invention is to provide a cross-cutting device which is adjustable in format length in very narrow steps or even infinitely variable, which does not have any of the disadvantages of the known cross-cutting devices described above and in which it is possible to achieve the optimum peripheral speed of the knife and counter cylinders work; this optimal peripheral speed lies between the web speed exactly in accordance with the peripheral speed and a slight forward speed of the two cylinders to about + 3% of the web speed.
  • the diameter of the knife cylinder and the counter cylinder is dimensioned such that the cylinder circumferential speed is the same or slightly greater (about + 3%) than the web speed in the longest format, further that everyone Cutter bars and each support bar are pivotally mounted in their associated cylinders about swivel axes lying within the cylinder surface and parallel to the cylinder axes of rotation, and that each cutter bar and each support bar are pivoted with an adjustable stroke during the cutting process, including zero stroke (for the longest format) , periodically against the web running direction and then back again into their starting position about their respective pivot axes in the circumferential direction of the knife cylinder or the counter cylinder.
  • the advantage of the design lies in the fact that the possibility of adjusting the knives and the cutting bars is significantly cheaper because only one pair of cylinders is required for all format lengths, whereas in previous cutting devices, as described at the beginning, a separate cutting cylinder and counter cylinder for all format lengths -Pair was required.
  • the design effort for subsequent orders is significantly lower and therefore cheaper, since the cutting cylinder and the counter cylinder can be the same for all printing cylinder sizes, whereas with previously known cutting devices, a new design of these cylinders was always necessary for new orders with different circumferential lengths the number of knives, the number of cylinders and the switching stages.
  • two knife bars offset by 180 ° to one another and in the counter cylinder two correspondingly offset support bars are provided in the knife cylinder, as previously known, all of which have a swiveling mechanism which can be adjusted simultaneously and to the same extent, from the optional one Individual parts can be used for both cutter bars and both support beams within one cylinder (e.g. cam disks).
  • An electrically operated swivel mechanism can be designed in such a way that on the outside of the end face of the knife cylinder and the opposing cylinder there is an electric motor adjustable in the angle of rotation, the output shaft of which carries the cutter bar or the support bar directly and the output shaft of which at both ends in the respective cylinder is mounted, and which thus itself forms the pivot axis of the cutter bar or the support beam.
  • this electric motor which of course has to be precisely controlled, can only work in one direction of rotation, then the cutter bar and the support beam must be rotated by about 180 ° in order to reach their starting position.
  • the electric motor can also be reversible in the direction of rotation, so that only a short backward movement with a small angle of rotation is required to reach the starting position.
  • a mechanical solution for the swivel mechanism is that a shaft is mounted in the knife or counter cylinder, which forms the swivel axis and carries at its one end projecting beyond the cylinder end face a gear which engages with an internal tooth segment , which is carried by a rotatably mounted ring which is driven by means of a separate gear wheel via a shaft and a manual transmission or a continuously variable transmission with different speeds set to the desired format length.
  • a cam disk can also be attached to the shaft of each cylinder, outside the same, adjustable in the circumferential direction, on which a cam roller runs, which directly causes the pivoting of the swivel shaft carrying the cutter bar or the supporting beam via a lever carrying it.
  • the easiest way to manufacture the cam is when it is designed as an eccentric circular cylinder.
  • a hydraulic design of the swivel mechanism consists in that a hydraulic cylinder with a piston is provided in the shaft of this cylinder, the piston rod of which is driven with a variable stroke synchronously with the cylinder rotation, this hydraulic cylinder being provided with a bore in the cylinder shaft and in the cylinder itself is connected to the second hydraulic cylinder, the piston of which, via a piston rod and a lever, directly causes the pivoting of the pivot shaft which carries the cutter bar or the support beam.
  • the piston rod of the first hydraulic cylinder can be driven, for example, via a swash plate which can be adjusted to different stroke sizes.
  • the invention makes it possible, in contrast to the known devices, where the two cylinders are exchanged for each format length, to fix the knife cylinder and the counter cylinder, i.e. not removable to store in the device.
  • This has the advantage of a structurally simpler, stiffer and more precise mounting of the two cylinders.
  • This more than compensates for the disadvantage that a knife change or a sharpening of the knives and an exchange of the cutting bar within the machine has to be carried out, because a format length change occurs many times more often than the exchange or regrinding of the knife or the exchange of the Cutting bar.
  • the knife cylinder is denoted by 1 and the counter cylinder by 2.
  • the knife cylinder 1 carries one (or two) knife bars 3 with the actual cutting knife
  • the counter cylinder 2 carries the support bars 4 for the cutting bars.
  • the cutter bar 3 is mounted so as to be pivotable about a pivot shaft 5 that lies within the circumference of the cutter cylinder 1
  • the support beam 4 is pivotable about a pivot shaft 6 that is also within the cylinder circumference.
  • the cutting strips carried by the supporting beam 4 are usually designed to be elastic.
  • an electric motor 8 is attached to the end face 7 of the knife cylinder 1 and - which is not shown - the counter cylinder 2, the output shaft of which drives the pivot shaft 5 directly.
  • the pivot shaft 5 is supported at both ends with bearings 9 and 10 in the knife cylinder 1. Exactly the same elements as the pivot mechanism are also what is shown in FIG. 2 but is not shown, provided for the counter cylinder 2.
  • the complete swivel mechanism is again only shown for the knife cylinder 1. It consists of a gear 11 mounted directly on the pivot shaft 5, which is in engagement with an internal toothing 12 which, as shown in FIG. 3, does not pass over the entire inner circumference of the ring 13, but only to the extent that this is possible for the pivoting movement of the Cutter bar 3 or the support beam 4 is required.
  • a second gear 14 is shown in each case, in the event that the knife cylinder 1 has two cutter bars with a knife and the counter cylinder 2 also has two support beams for elastic cutting strips.
  • the ring 13 carrying the internal toothing 12 is rotatably supported by means of a bearing 15.
  • the rotary drive of the ring 13 takes place by means of a drive gear 16, the drive shaft 18, which is supported by bearings 17, is preferably driven by the main drive of the device via a manual gearbox corresponding to the various desired format lengths;
  • a continuously variable transmission can also be provided instead.
  • a circumferentially adjustable cam 20 in the form of an eccentric circular cylinder is fastened, on which a cam roller 21 rolls, which supports this cam roller 21 Crank 22 directly causes the pivoting of the swivel shaft 5 or 6 carrying the cutter bar 3 or the support beam 4.
  • the adjustability of the eccentric circular cylinder on its shaft 19 serves to change the stroke of the knives and the cutting bars.
  • FIGS. 7 and 8 differs from that according to FIGS. 5 and 6 only in that the eccentric circular cylinder 20 is replaced by a cam disk 23.
  • a hydraulic cylinder (not designated in any more detail) is provided in the shaft 19 of the knife cylinder 1, in which there is a piston 24 which is driven with a variable stroke synchronously with the cylinder rotation.
  • This hydraulic cylinder is connected via a bore 25 in the cylinder shaft 19 and in the knife cylinder 1 itself to a second hydraulic cylinder 26 provided in the latter, the piston or piston rod of which causes the pivoting of the pivot shaft 5 directly via a lever 27.
  • the piston rod 28 of the first hydraulic cylinder is set back and forth by a swash plate 31 via a joint 29 and a rod 30.
  • the stroke of this back and forth movement can be changed either by changing the inclined position of the swash plate 31 or by shifting the articulation point 32 of the rod 30 on the swash plate 31 in the radial direction thereof, in each case in accordance with the desired format length.
  • a fixed gear 32 and 33 is provided outside this cylinder 1, 2, coaxially with the latter, on which a gear 34 and 35 rotating with the cylinder 1 and 2 rolls, which sets a rod 37 in a reciprocating motion via a crank 36, the other end of which causes the pivoting of the pivot shaft 5 via a second crank 38.
  • the knife can cylinder and the counter cylinder are manufactured completely identically, which of course simplifies and reduces the cost of manufacture.
