Definitions

  • the invention relates to a controllable switch in a paper transport device of a web-fed rotary printing press.
  • Controllable characters 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 publication also shows a typical tape transport system that shows how printed, folded signatures are transported between tapes from one place to a second.
  • the switch segments used up to now 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 advantages which can be achieved with the invention consist in particular in that, in addition to avoiding the above-mentioned disadvantages of the prior art, the point of impact of the signatures does not lie 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.
  • the signature inlet between the conveyor belt and the switch segment can initially be designed in a funnel shape.
  • 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 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 surfaces of the above-mentioned surfaces 23, 26, 27, 28.
  • Conveyor belts e.g. B. the lower conveyor belt 3 or 9.10.
  • the arrangement of the intermediate spaces 34 between the tines 33 makes it possible in an advantageous manner to in each case the run-up angle ⁇ ; ⁇ , under which the signatures 1 on the - depending on the course - involved area z. B.
  • 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. 2); in the example thus connects the conveying paths 5 and 12.
  • 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 with its ends to a bearing journal in a cohesive 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.
  • FIG. 3 In a second solution of the inventive concept (FIG. 3), all parts, with the exception of the switch segment 14, are the same as those of the first solution described above.
