Definitions

  • the invention relates to a device for redirecting signatures clamped between first and second conveyor belts according to the preamble of claim 1.
  • EP 02 54 037 A1 discloses a device for dividing a stream of signatures into two partial streams. This is done by the fact that on the circumference of two opposite, eccentrically and rotatably mounted control rollers, there are conveyor belts between which the signatures are clamped. The two control rollers oscillate in time and alternately press the signatures against a deflecting edge of a guide wedge via the conveyor belts. From there they arrive in a first or second transport path.
  • a device for sorting out paper sheets guided between conveyor belts and the like is known, one of two transport paths optionally being blocked. This is done in that a deflecting member presses the conveyor belts against a guide surface of a guide wedge. The second transport path is released during this time.
  • the invention has for its object to provide a device for rerouting signatures from a stream of signatures in two sub-streams in two transport paths.
  • the advantages that can be achieved with the invention are, in particular, that the front edges of the signatures do not abut the leading edge of the guide wedge and can thus cause a jam.
  • the service life of the conveyor belts is increased by the fact that they do not have to drive control rollers.
  • Fig. 1 is a schematic side view of a
  • FIG. 2 shows a schematic side view of the device according to FIG. 1, but in a second working position with release of a second transport path for the signatures;
  • FIG. 3 shows a section III - III in FIG. 1; (enlarged view)
  • FIG. 4 shows a section IV - IV in Fig. 2. (enlarged view)
  • the device essentially consists of a first cam roller or cam row 1, with one or a plurality of high cams 20, 21, 22 and low cams 17 and a second cam roller or cam row 2, with one or a plurality of high cams 25, 26, 27 and low cams 30, 31, 32, which mesh with each other and driven and are arranged axially parallel to each other.
  • the signatures 6; 7 were previously generated in a known manner by cross cutting a strand of paper. They can be folded or unfolded.
  • the conveyor belts 3; 4 continued at the end of run zwi cke l 11 to z. B. downstream processing stations, longitudinal fa ices directions, etc.
  • Each cam row of the first upper cam roller 1 alternately has one or more cams 17, each with a small radius r1 and a low control surface 18 (FIG. 3), as well as one or more high cams 20 or 21 or 22 with a high radius r2 and a high control surface 23 (Fig. 4).
  • a stroke b1 between low and high control surface 18, 23 can be between two to six millimeters.
  • a stroke b2 between the low and high control surfaces 25 or 26 or 27 of the high cams 25 or 26 or 27 can accordingly also be between two and six millimeters.
  • the cam roller 1 can be designed in various ways, for. B. from a tubular roller with attached, in circumferential direction streak-shaped, spaced apart cams 20; 21; 22 exist or have a plurality of cam disks spaced apart a1, which e.g. B. by Abs tandsha l te rn 34 be kept at a distance.
  • the second cam roller 2 can have the same construction principles as the first cam roller 1 be formed, but with a smaller diameter.
  • the z. B. annular cam roller 2 has a clear distance a2 from each other in the axial direction and extends in circumferential direction high cams 25 or 26 or 27, each with a large radius r3 and high control surface 28 and each in circumferential direction the roller 2, the low cams 30 adjoining the high cams 25 to 27; 31; 32 with a small radius r4 and respectively lower control surfaces 33.
  • the cam rollers 1, 2 can in addition to the embodiments already performed, such as. B. put on a roll of stripe-shaped control surfaces or by spacers 34 spaced cam disks 36 (FIGS. 3 and 4), but also consist of a cross-sectionally circular, but eccentrically mounted roller with circumferential annular grooves.
  • a guide wedge 13 which is fixed to the frame and has an upper guide surface 14 and a lower guide surface 16 is provided.
  • the cutting end 10 may be both sharp-edged but also rounded.
  • the guide wedge 13 can, for. B. - in the axial direction of the cam roller 1; 2 seen -, from several of each other spaced apart line 37; 38; 39; 40 exist, but also be comb-like, with "tines" and intermediate spaces.
  • the thin ends 10 of the guide wedge 13 or individual lines 37 to 40 each come between the axially adjacent cams 20; 21; 22 to lie.
  • the Ei nze l Lei t kei le 37 to 40 are in the axial direction of the cam roller 1; 2 spaced apart from each other attached to a side frame 44.
  • the conveyor belts 3; 4 are then intermittently pressed into the free spaces 42 or 43 between or next to the individual lines 37 to 40 by the high cams 20 to 22 or 25 to 27.
  • the conveyor belts 3; 4 plunge into these gaps with their entire thickness d or only a part of it.
  • the high control surface 23 of the high cam 20 to 22 then presses the upper conveyor belt 3 lying against it over its entire or partial thickness d into a free space between two “guide prongs” of the comb-shaped guide wedge 13 or between two eggs it is 37 to 40 or one to the left or right of them.
  • the entire or partial thickness of the upper conveyor belt 3 moves through the free space enclosed by virtual extension — seen in the axial direction of the cam roller 1 or 2 — the upper 14 and lower guide surfaces 16. In fact, it meshes from below the lower guide surface 16 to beyond the upper guide surface 14.
  • the guide surfaces 14; 16 of the individual lines 37 to 40 are each flat. According to another embodiment, the guide surfaces, in particular the parts of the guide surfaces 14; 16 of the individual lines 37 to 40 are each concavely curved.
  • the cam roller - here the cam roller 1 - on which the stream of signatures 5, 6 first comes up has an integer multiple of cams, like the second cam roller 2 interacting with it, e.g. B. 6 cams to 2 cams.
  • This measure allows thicker signatures 6 to be deflected without harmful displacement forces occurring between the inner and outer layers of the signature 6.
  • the virtual extension of the upper guide surface 14 - seen in the axial direction of the cam roller 1 or 2 - to the left and right is referred to as a virtual guide surface 19.
  • the virtual extension of the lower guide surface 16 - seen in the axial direction of the cam roller 1 or 2 - to the left and right is referred to as the virtual guide surface 24.
  • the device works as follows: The between the conveyor belts 3; 4 pinched signatures 6 fed to the inlet 8; 7 are alternately on the transport paths 51; 52 distributed.
  • a signature e.g. B. Signature 6 due to the position of the cam roller 1 with the low control surface 18 of the low cam 17 on the exposed upper guide surface 14 of the guide wedge 13 sliding from the upper conveyor belt (system) 3 to the transport path 51.
  • the high control surface 28 of the high cam 25 of the lower cam roller 2 has canceled the lower conveyor belt 4 of the lower conveyor belt system 4 to such an extent that its entire or partial thickness is due to a free space between two guide prongs of a comb-like guide wedge 13 or each between two individual lines 37 to 40 or to the left or right next to them in the direction of transport path 52.
  • the path for the signatures 6 along the lower guide surface 16 of the "Tines” or single parts 37 to 40 temporarily blocked.
  • Both conveyor belts 3; 4 then run above the leading edge 12 of the “prongs” or individual lines 37 to 40 (FIG. 1).
  • the entire or partial thickness of the lower conveyor belt 4 moves through the free spaces, which are enclosed on both sides by the virtual extension - seen in the axial direction of the cam roller 1 or 2 - of the upper 14 and lower guide surfaces 16. Namely, coming from above the upper guide surface 14 to below the lower guide surface 16.
  • the signature 6 in the upper path finally passes with its end the thin end 10 of the tines or individual lines 37 to 40.
  • the high control surfaces 23 of the high cams 20 to 22 of the first (upper) work.
  • Cam roller 1 against the low control surfaces 33 of the low cams 30 to 32 of the cam roller 2 in order to guide the signature 7 following the signature 6 along the lower guide surface 16 to the lower transport path 52.
  • a signature 6 or 7 or the inner surface of a conveyor belt 3 or 4 are passed alternately, slidingly or at a short distance, for . B. of 0.1 mm.
