Definitions

  • the invention relates to a method for cutting register control in a web-fed rotary printing press.
  • DE 102 45 962 A1 describes a method for cutting register control in a web-fed rotary printing press in which a printing material is guided via traction units each with adjustable overfeed to a cross-cutting device after leaving the last printing unit, wherein one of the traction units is changed with respect to their peripheral speed to adjust the cut register ,
  • This procedure has the advantage of a shorter setting time compared to the cut register setting by means of a deflecting roller which can be displaced or pivoted transversely to the transport direction of the printing material web.
  • the object of the present invention is to further develop this known method in terms of a further improvement of the control loop dynamics as well as simplification.
  • the traction unit used for the cutting register setting is already in the printing unit, i. that the printing units themselves are already adjusted to move the print image to achieve the desired cutting position. With the adjustment of the cutting register error is thus set where it begins to emerge, whereby the use of guide rollers for cutting register adjustment can be kept to a minimum.
  • the principle of the invention is no longer applicable. Rather, it must be taken into account in such a train unit that it has to have to maintain the web tension in each individual entering the strand web or partial web at any time a lead over that or train at the highest speed. Therefore, the peripheral speed of such a train unit must correspond to that of the train units of the currently highest speed train plus an overfeed.
  • FIG. 1 shows a schematic partial side view of a printing press.
  • a printing substrate 2 is printed in a printing unit 1, which enters into the downstream units of a printing press together with other, not shown in the figure printing units webs 12 and 22.
  • the web 2 like the webs 12 and 22 coming from the other printing units, is first cut longitudinally into two part webs 3A and 3B.
  • a partial web 3B is turned in a turning unit 4, before the two partial webs 3A and 3B with those from the other webs 12th and 22 cut partial webs are brought together into a strand 5 and this is folded at a funnel 6.
  • the funnel 6 By folding the funnel 6, the strand 5 is rotated by 90 ° and then runs to a knife cylinder 7, where it is cross-cut into individual sections.
  • the position of the cut must be matched to the position of the printed image in order to maintain a constant, predetermined distance of the printed image from the cut edges in the longitudinal direction.
  • an optical sensor 8 is arranged, which detects the position of a cutting register mark on the partial web 3A, 3B and outputs a respective measurement signal M.
  • the knife cylinder 7 may be equipped with an incremental encoder which supplies a clock signal having a predetermined number of pulses and a reference pulse per revolution of the knife cylinder.
  • the number of such pulses generated since that time since the last reference pulse can be used as a measure of the position of the cut register mark.
  • Such a measured position of a cutting register mark provides a measure of the actual value of the cutting position, i. for the expected distance of the cut from the mark and can be used to control the Thomasre-gister the respective substrate web.
  • all further train units conveying the web 2 are adjusted simultaneously in their circumferential speed.
  • this concerns the traction unit 11 arranged in front of the longitudinal cutting device, with the result that the cutting register adjustment propagates up to there in the web 2 approximately at the speed of sound of the printing stock which, in the case of paper of the order of 3000 m / s, that is far above the transport speed of the web 2. It is understood that this principle can be applied to any number of further subsequent train units, provided that these train units all alone promote the web 2.
  • the cut register setting of a turned partial web 3B may require an additional adjusting element in the form of a displaceable roller, since an additional error contribution may arise on the additional path in the turning unit 4, which must, if necessary, be compensated separately from the regulation of the straight running partial web 3A.
  • a traction unit that no longer promotes a web 2 or part web 3A, 3B cut from it alone, such as the recognizable in Fig. 1 tractor unit 6A, which promotes the strand 5 after its merger to the hopper 6 back
  • the principle of the invention is no longer applicable because there is no unique assignment of the tractor unit 6A to a single lane 1, 12, or 22.
  • Such a train unit 6A acting on an entire strand 5 must be considered to be capable of maintaining the web tension in each one in the strand 5 incoming web or partial web at any time must have a lead over that or train at the current highest speed.
  • the straight-ahead partial web 3A cut from the web 2 is accelerated by synchronous speed increase of the printing units 1 A to 1 D and the tractor unit 11 for correction of the cutting register error so that it is currently within the line 5 the web with the highest speed , then the speed of the tractor unit 6A must be increased so that it has an advance required to maintain the intended tension in the sub-railway 3A in relation to the last preceding tractor unit acting on the sub-railway 3A.
