Definitions

  • EP 00 54 963 B1 is a
  • conveyor belts After passing through the gap, conveyor belts form a run-out in between. in the
  • a running tongue with its cutting edge in the gap and wedge-shaped in cross section is provided from the running gap.
  • the first and second conveyor belts each run at a distance along guide surfaces of the guide tongue.
  • EP 02 54 037 A2 describes a device for dividing a stream of signatures by means of a conveyor belt system.
  • the conveyor belts are deflected by means of eccentric rollers.
  • the invention has for its object a To create a device for dividing a stream of signatures into two signature sub-streams.
  • the circumferences or control surfaces of the two cam rollers simultaneously serve to guide the belt, so that separate belt guides are not required. Furthermore, it is particularly advantageous when processing thick signatures if a second cam roller has a larger circumference than a first cam roller. It is advantageous that a roller for deflecting the conveyor belt system is wrapped at least 45 ° by the conveyor belt system. This ensures that the signatures are kept secure.
  • the roller for deflecting the conveyor belt system has a circumferential length that is at least three times the maximum length of the signatures to be transported. This creates d. H. when the signatures change direction, less harmful displacement forces between their inner and outer layers.
  • FIG. 1 shows a cross section for dividing a stream of signatures through a device in a first working position with release of a first transport path for the signatures.
  • FIG. 2 shows a device according to FIG. 1, but in a working position with release of a second transport path for the signatures;
  • FIGS. 1 and 2 shows a reduced illustration of the device according to FIGS. 1 and 2.
  • the device consists essentially of a first Roller, e.g. B. cam roller 1 and a second roller, e.g. B. cam roller 2, which are co-drivable and axially parallel to each other.
  • the second cam roller 2, but also the first cam roller 1, can be designed as deflection rollers which a belt system 6 z. B. serve at least 45 °, preferably between 90 ° to 180 ° for deflection.
  • the circumference of the second cam roller 2 is somewhat larger and more than 90 ° from the lower and upper conveyor belts
  • Signatures 7; 8th; 36 consist in a known manner of one or more paper webs with layers of one or more sheets produced by cross cutting. They can be folded or unfolded.
  • the tapes 3; 4 run into a gap 9 between the cam rollers 1; 2 and then separate at an acute opening angle Alpha, z. B. of 10 ° from each other.
  • the conveyor belts 3; 4 an outlet run 16.
  • a guide tongue 17 which is fixed to the frame and has a wedge-shaped cross section is arranged.
  • a cutting edge 15 of the guide tongue 17 points in the direction from the running angle 16, ie in the direction of the gap 9 between the segment rollers 1; 2. It is positioned in the immediate vicinity of the gap 9.
  • the guide tongue 17 has an acute opening angle Beta, z. B. of 10 ° and has on the one hand in the opening, expiring part of Gap 9 and on the other hand extends in the direction of the guide rollers 13; 14th
  • the guide tongue 17 has a lower and upper straight or curved guide surface 18 and 19, on which the signatures 7 and 8 are alternately guided past them or the inner surfaces 21; 22 of the conveyor belts 3; 4 also sliding or a short distance z. B. 0.1 mm are passed.
  • the lower conveyor belt 28 lies with its inner surface 31 against the inner surface 21 of the conveyor belt 3 and forms a further signature transport path B for the signatures 7.
  • the upper conveyor belt 29 lies with its inner surface 33 against the inner surface 22 of the conveyor belt 4 and forms one Signature transport path C for the signatures 8 (split signatures 7, 8).
  • the conveyor belt 3 also forms, together with the conveyor belt 28, a second, that is to say cam roller 1 close, removal conveyor belt system 38.
  • the conveyor belt 4 also forms, together with the conveyor belt 29, a third, ie cam rollers 2 close, laxative Conveyor belt system 39.
  • each conveyor belt system 6; 38; 39 are in the axial direction side by side on the cam rollers 1; 2 arranged.
  • the first cam roller 1 has a "low” cam 41, which extends over 180 ° of its circumference and extends continuously in the axial direction of the cam roller 1, with a control surface 46 and a low radius r1. Furthermore, the cam roller 1 has a “high” cam 42, which extends over a further 180 ° of its circumference and also extends in the axial direction, with a control surface 47 and a low radius r2.
  • the lifting height d of the cam roller 1, for. B. of two to three millimeters, corresponds to the difference between the radii r1; r2.
  • the second cam roller 2 can be designed in the same way as the first cam roller 1.
  • the second cam roller 2 can also several and evenly distributed on it around its circumference, for. B. three "low” cams 43 each with a small radius r3 and control surfaces 48 and three "high” cams 44 each with a high radius r4 and control surfaces 49.
  • the number of cams 43; 44 of the second cam roller 2 is preferably an integral multiple of the number of cams 41; 42 of the first cam roller 1.
  • the lengths l z. B. the control surfaces 46 to 49 of the cams 41 to 44 of the cam roller 1 and 2 are preferably the same, but need not be.
  • Cam roller 2 a six times maximum length
  • the entire cam rollers 1; 2 or at least their high cams 42; 44 can be interchangeable, so that, for example, instead of the described "sixf e Ldrigen” (3 high and 3 low cams) cam roller 2 with the same circumferential length a "fourf e Idige” (z. B. with two high cams, the length of which is twice the length the cam corresponds to the sixfold cam roller) can be used with an adapted counter roller.
  • this “vi erf e Idr i gen” cam roller for example, the stream of signatures is divided into two partial streams, two alternating signatures in succession to one partial stream and only one signature each to a second partial stream.
  • the cams 43; 44 extend z. B. consistently in the axial direction of the cam roller 2.
  • a lifting height e of the cam roller 2 corresponds to the lifting height d
  • cam roller 1 It is also possible to have a plurality in the axial direction of the cam roller 1; 2 spaced cams 41, 42; 43, 44 to be provided.
  • the device operates as follows. Between the conveyor belts 3; 4 of the first tape system 6, spaced signatures 7 and 8 are guided in a clamping manner (FIG. 1).
  • the tape system 6 can e.g. B. run underneath a cross-cutting device for generating the signatures in an approximately vertical direction until it reaches the second cam roller 2, which also serves as a deflection roller, and through it a change in direction of> 90 °, eg. B. 120 °, experiences.
  • the signatures 7 and 8 then pass one after another to run between 16 between the conveyor belts 3 and 4.
  • the second segment roller 2 presses with one of its "high” cams 44 against the outside of the conveyor belt 4 and moves it in the direction of the guide tongue 17. In the process, it lies down
  • the cam rollers 1; 2 preferably have the same peripheral speed.
  • a clear distance a of the gap 9 becomes the one formed between a "high” cam 44 of the cam roller 2 and a “low” cam 41 of the cam roller 1 (FIG. 1) or between a "low” cam 43 of the cam roller 2 and a “high” cam 42 of the cam roller 1.
  • the essence of the invention is that the first and second conveyor belts 3; 4 are arranged in a reciprocating manner on the guide surface 18 or 19 of the guide tongue 17 assigned to them. Intermittent means that z. B. at the same or almost the same point in time, both a first transport path B on the cutting edge 15 is closed or closed for the most part and a second transport path C on the cutting edge 15 is opened and vice versa.
  • Closing a transport path B or C is only necessary to the extent that a signature 7; 8 can not penetrate this transport path B or C, that is, a small distance, z. B. of a few hundredths of a millimeter, between a conveyor belt 3 or 4 and cutting edge 15 of the guide tongue 17.
  • a transport path B or C is closed, the inner surface 21 or 22 of each transport belt 3 or 4 is caused to alternate with the cutting edge 15 of the guide tongue 17 cooperates, so that a guide for the beginning of the signatures 7 and 8 is formed already in the front part of the runaway portion 16 of the conveyor belts 3 and 4.
  • the conveyor belts 3; 4 can be arranged on the control surfaces 41, 42; 43, 44 of the cam rollers 1; 2 concerns. Reference numerals list
