Definitions

  • the invention relates to a device for superimposing strands, which are formed by longitudinal cutting of at least one web printed in a web-fed rotary printing press, by means of turning bars before entering a downstream folder.
  • Such a device is already known from DE-Laid-Open Specification 35 01 389, in which a number of turning bars lying one above the other at uniform intervals are provided. Each turning bar is assigned a deflection roller. All deflection rollers are arranged on the side next to the turning bars. This makes access to the turning bars considerably more difficult.
  • the invention has for its object to further develop a device of the type mentioned above that, despite the possibility of inserting a strand overturned or unthreaded between two other strands, the material and operating effort is reduced.
  • the arrangement according to FIG. 1 comprises three reel changers 1, which each deliver a web 2 a, 2 b, 2 c to one of the three printing units 3 above for printing in the production shown.
  • the printing units 3 are followed by cutting devices 5 for each web, eight turning bars 6, 7, 8, 9, 10, 11, 12, 13, which are each combined in pairs, four double-swivel controls 14 and a downstream folder 15.
  • cutting devices 5 each of the Lanes 2 a, 2 b, 2 c cut once in the longitudinal direction.
  • Fig. 2 six strands 16, 17, 18, 19, 20, 21 produced by longitudinal section are seen running into the planes of the individual pairs of turning bars 6 to 13. For reasons of clarity, the distances between the pairs of turning bars 6 to 13 are shown larger than necessary.
  • Each turning bar 6 to 13 can be implemented from the operating side 26 by 90 °.
  • the storage of the turning bars 6 to 13, which permits implementation, is known per se and is therefore not shown.
  • the space accommodating the turning bars 6 to 13 is spatially limited by the wall 25 on the drive side and the wall 26 on the operating side, both of which have an operating window 27.
  • two parallel guide rails 28 a, 28 b are mounted, which are used for the height-adjustable mounting of two deflecting rollers 22, 23.
  • the alternatively possible positions 29 of the deflecting rollers 22, 23 are indicated by a circle.
  • the longitudinal axes of the deflecting rollers 22, 23 run parallel to the running direction of the tracks 2 a, 2 b, 2 c marked with the arrow a.
  • the deflecting rollers are not shown in FIG. 1 for reasons of clarity.
  • a stationary, driven pull roller 24 is provided, the longitudinal axis of which runs parallel to the longitudinal axes of the deflecting rollers 22, 23.
  • the two strands 16, 17 of the web 2 a run into the plane tangent to the underside of the turning bar 6.
  • One strand 16 is carried out unturned under the turning bar 6.
  • the other strand 17 is deflected by means of the turning bar 7 used as an angle turning bar 7 by 90 ° in the direction of the deflecting roller 22 and guided through the operating window 27 on the operating side 26.
  • the further path of the strand 17 leads over the deflecting roller 22, the driven pull roller 24, which compensates for the different tensile conditions of the strands 16, 17, and the deflecting roller 23 to the underside of the turning bar 11.
  • the turning bar 11 acts as a parallel turning bar and brings the strand 17 over the strand 19.
  • the strand 17 is overturned, that is to say the side which was at the start of the turning bar 6 is now at the bottom.
  • the two strands 18, 19 of the web 2 b likewise produced by longitudinal section run tangentially to the underside of the turning bars 8. Then one strand 18 continues to run directly without using a turning bar. The other strand 19 is brought into alignment with the two strand bars 8, 9, of which the first serves as an angle turning bar and the second as a parallel turning bar, over the first strand 18.
  • the third web 2 c runs as already described for the web 2 b over the turning bars 12, 13. Here, the strands 20, 21 are guided one above the other without rushing.
  • Fig. 3 the positions of the two movable deflecting rollers 22, 23 and the pull roller 24 are shown again. Furthermore, the positions of the axes of the turning bars 6 to 13 are indicated by dash-dotted lines.
  • another deflecting roller 30 is indicated at the height of the deflecting roller 23 on the right outside the structure, which is delimited by the guide rails 28 a, 28 b, lying perpendicular to the deflecting rollers 22, 23.
  • the turning bar 11 is implemented so that the strand 17 runs through it from the turning bar 11 against the direction of the arrow shown in FIG. 2.
  • the strand 17 is then deflected by the deflecting roller 30 by about 180 °, so that it leaves this deflecting roller again in the direction of the other strands.
  • the strand 17 can also be mixed with the other strands either via the turning bar 9 or 13. In this case, no web is fed to the pair of turning bars 8, 9 or 12, 13.
  • the possibility of displacing the deflecting rollers 22, 23 without the webs being drawn in also creates good accessibility to the turning bars 6 to 13 through the operating window 27.
  • Another advantage of this device is that the two deflecting rollers 22, 23 can be positioned by a motor.
  • the setting can therefore be made from a control panel.
  • two sliders 31 a, 31 b are movably arranged along the two guide rails 28 a, 28 b, which are designed as toothed racks, for holding each deflecting roller 22, 23.
  • a drive motor 32 is mounted on each of the two sliding pieces 31 a, the guide rail 28 a.
  • a fixed initiator 34 is provided for each possible position 29 of the deflecting rollers 22, 23.
  • Each slider 31 a, 31 b has a guide housing 36 which engages around the guide rail 28 a or 28 b on three sides.
  • a pinion 33 is arranged, which sits on the shaft of the drive motor 32 and engages in the toothing.
  • Each slider 31 a, 31 b also has a bearing 44 for an axis 35 of the deflection roller 22 and 23, respectively.
  • a movable latch 39 can interact with the notches 37.
  • the bolt 39 is firmly connected to a piston 41.
  • the piston is guided in a cylinder 38.
  • a return spring 40 acts on one side of the piston.
  • a compressed air supply line 42 opens out on the other side.
  • the initiator 34 assigned to this position is activated.
  • the drive motor 32 now moves the deflection roller 22 and 23 via the pinion 33 and the toothed rack 28.
  • the plate 43 which is transverse to the initiator 34 triggers a signal in the latter.
  • this signal triggers the shutdown of the drive motor 32.
  • a Control valve opened and thereby the pneumatic cylinder 38 is pressurized with compressed air.
  • the piston 41 moves the bolt 39 in the direction of the opposite pyramid-shaped notch 37, so that the bolt 39 engages and thus firmly locks the deflecting roller 22 or 23, with the sloping surfaces of the notch 37 and the bolt 39 accurately positioning the slide 31 a or 31 b and thus the deflecting roller 22 a or 22 b.
