Definitions

  • the invention relates to a controllable diverter in a paper transport device, in particular a web-fed rotary printing press, according to the preamble of claim 1.
  • Controllable switches in a paper transport direction of a web-fed rotary printing press have become known from DE-PS 6 78 472.
  • DE-OS 22 33 750 shows a switch controllable in time in the output of a folder of a web-fed rotary printing press. This document also shows a typical tape transport system that shows how printed, folded signatures are transported between tapes from one place to a second.
  • EP-A-00 84 931 has disclosed a controllable switch which forms an acute angle with the conveyor belt in an end position of the switch segment. However, with this switch the signatures run on the tip side of the switch segment.
  • the switches have to switch 60,000 changes of direction per hour, which is more than 16 times per second. Due to the high production speed and z. B. mineralized additives in paper, the service life periods have of course also become shorter. The Wear causes u. U. production disruptions, but also machine downtimes that are necessary when the worn switch segments are replaced.
  • the switch segments previously used are characterized in that the signatures to be diverted run up against a flat, relatively thin tip of the switch segment and quickly weaken this tip by material removal.
  • the invention has for its object to provide a switch segment as part of a switch in a signature transport device of a web-fed rotary printing press, in particular, a folder with which a long service life with respect to wear can be achieved even at high production speeds.
  • the point of impact of the signatures is not on the legs of the thin, flat-drawn tip of the switch segment.
  • the point of application of force for controlling the switch segment does not have to be in the end opposite the tip of the switch segment, so a smaller drive torque is necessary.
  • the turnout segment can be of shorter construction compared to flat-drawn turnout segments, so that the distance over which signatures without double tape guidance be promoted, becomes shorter. At least for one turnout, the signature inlet between the conveyor belt and the turnout segment can initially be funnel-shaped.
  • the switch segments since they are made thicker, can be made comb-like at one or both ends, so that the conveyor belt and / or guide rollers can run in the space between two prongs of the switch segment. This ensures that the upper and lower conveyor belts can run closer together in the switch segment area. This also enables a more compact construction of the entire turnout and thus short deflection paths without double conveyor belt guidance.
  • the lower conveyor belts 3 run, for example, over the lower belt guide rollers 7 and 8, which are known to be fastened to lower cross members between the side frames and rest on lower conveyor belts 9 of a third conveyor path 12.
  • Lower conveyor belts 3 and upper conveyor belts 2 leave their common conveyor path 5 immediately after the belt guide rollers 4 and form an acute-angled space 13 between them, in which a switch segment 14 of a switch 16 for deflecting printed products z.
  • B. Signatures 1 place.
  • the belt guide rollers 6 are assigned deflection rollers 17 so that the conveyor belts 9 touching them form an upper inlet gusset 18 for the signatures 1 of the second conveyor path 11 with the upper conveyor belts 2.
  • the tape guide rollers 7 and 4, the belt guide roller 8 and a deflecting roller 21 are assigned so that the conveyor belts 3 and 10 form a lower inlet gusset 22 for the signatures 1 of the third conveyor path 12.
  • the switch segment 14 has an upper guide surface 23, a lower guide surface 24, a lower ramp surface 26, a left end surface 27, a right end surface 28, a front and a rear side surface 29, 31.
  • the upper and lower guide surfaces 23 and 24 are either totally or approximately adapted to the shape of the conveying path 11, 12 of the upper and lower conveyor belts 2 and 3 respectively assigned to them.
  • z. B the upper guide surface 23 in a straight line (flat), the lower guide surface 24 in the first section of the run-up surface 26 straight and then curved (concave).
  • a pivot axis 32 of the segment lies outside the outline of the cross sections of the switch segment 14; 1 above the upper guide surface 23 and in the middle third of the width c of the switch segment 14.
  • the thickness d1 of a first end 19 of the switch segment 14 with the end face 27, which faces the inlet of the signatures 1 in the switch space 13, in the exemplary embodiment, the left end face 27 (turnout input) can be equal to or a multiple of the thickness d2 of the second end 20 of the turnout segment 14 and the right end face 28, which lies opposite the inlet gussets 18 and 22 of the subsequent conveying paths 11 and 12.
  • the switch segment 14 Over its length between the side frames, the switch segment 14 is on its first 19 and if necessary also on its second end 20 with spaces between the prongs 33 or 36 (tooth-like projections), designed like a comb, ie it has a plurality of wide tines 33; 36.
  • the tines 33; 36 serve to deflect the direction of the signatures 1 and have partial areas of the above-mentioned areas 23, 26, 27, 28.
  • Conveyor belts run through spaces 34, 35 between the prongs 33 and 36, e.g. B. the lower conveyor belt 3 or 9.10.
  • Run-up angle is the acute angle at which an extension of the upper guide surface 23 intersects a plane along the surface of the lower conveyor belt 3 when the switch segment 14 has reached a first switch end position (FIG. 1); in the example, the funding routes 5 and 11 are connected.
  • the run-up angle ⁇ is the acute angle at which an extension of the run-up surface 26 or this intersects an imaginary plane along the transporting surface of the conveyor belt 3 when the turnout segment 14 has reached a second turnout end position (FIG.
  • the run-up surface 26 can advantageously form a large angle with the end surface 27.
  • the switch segment 14 extends over the entire width of the conveying path of the signatures 1 and is connected to its ends with a bearing journal in a materially bonded manner.
  • the trunnions are stored in side frames.
  • a journal is e.g. B. connected to a sliding crank gear, which is positively connected to a drive running synchronously with the main machine.
