Definitions

  • the invention relates to a machine for manufacturing or treatment a material web, in particular paper or cardboard web, with a Rope guide for threading a web edge strip, the two endless ropes includes, which can be brought together to form rope shears.
  • a paper machine of this type is for example in DE-C-40 37 661 described.
  • the two ropes for Forming a so-called rope shear converge or converge, so that the tip of the edge strip is grasped and transported further can be.
  • a deflection device can be installed in the web running direction in front of the cable shears be provided by the incoming tip of the edge strip diverted laterally from the area of the web width into the rope shear becomes.
  • the aim of the invention is to provide an improved machine of the type mentioned To create a way in which the aforementioned disadvantages are eliminated.
  • a machine for Production or treatment of a material web in particular paper or Cardboard web
  • a rope guide for threading a web edge strip which includes two endless ropes that form a rope cutter are mergable and their careers for positioning the rope cutter in a threading position within a machine direction extending plane perpendicular to the material web is changeable.
  • the position of the rope cutter is within the machine Machine running direction, perpendicular to the material web Level changeable.
  • the two ropes of the rope guide are preferably independent of the Position of the rope cutter in each case only in a machine running direction extending plane perpendicular to the material web.
  • the position of the cable shears is advantageously generally in the machine running direction variable.
  • the two ropes of the rope guide for positioning the rope cutter in a threading position in the area of a device, in particular a path scanner or the like, feasible and retractable to allow unhindered movement of the facility to enable.
  • the two are Ropes of the rope guide for positioning the rope shears in a threading position can be guided through the frame of a web scanning device and retractable to release the path scanning level.
  • the cable shear is advantageously between a threading position in the the two ropes of the rope guide through the frame of a web scanner are passed, and a retracted position adjustable, in which the web scanning device is released again.
  • the cable shears that grip the tip of the web edge strip can therefore for example through the frame of a scanner in a threading position that is adapted to the tip of the a preceding machine element such as a press roll or a coming edge strip drying cylinder.
  • the edge strip can, for example, through an air shaft or transported a conveyor belt to the relevant takeover point become.
  • Another advantageous embodiment of the embodiment according to the invention is characterized by the fact that the cable guide Machine running direction in front of a web scanning guide section and one downstream of the web scanner lying guide section includes that the two ropes of the Rope guidance between these two guide sections from each other separately on opposite sides of the web scanner are guided and that at the beginning of the rear guide section a rope cutter is formed, which takes over the web of material the front guide section through the frame of the web scanner through into a takeover position and for transferring the Material web in the rear guide section again in a behind the Path scanning device lying retracted position is adjustable.
  • the two ropes can be used to form the rope shears on two rollers be guided, which can be positioned accordingly via an adjusting device are.
  • the cable guide can be used, for example, to thread a strip of web edge be provided in the dryer section. Basically, the rope guide however also for threading a web edge strip into another Machine element may be provided.
  • Figure 1 shows a schematic partial representation of a machine 10 for manufacturing or treatment of a web of material, which is in particular can be a paper or cardboard web.
  • a cable guide 16 is provided, for example in the present case serves to thread a web edge strip into the dryer section.
  • This cable guide 16 is also in a simplified schematic representation shown again in FIG.
  • the cable guide comprises 16 two endless ropes 18, 20 which in the region of two rollers 22, 24 for Forming a rope cutter 26 are merged.
  • the career of these two endless ropes 18, 20 by means of an adjusting device 28 for positioning the cable shears 26 in a threading position E inside one extending in the machine running direction L to the material web vertical plane can be changed accordingly.
  • the roller arrangement is made by means of the adjusting device 28 22, 24 with constant distance between the rollers 22, 24 shifted accordingly.
  • the cable shear 26 of the roller arrangement 22, 24 is thus maintained. It is thus the position of the cable shear 26 within the extending in the machine direction L, perpendicular to the material web Level changeable.
  • the two ropes 18, 20 of the Rope guide 16 regardless of the respective position of the rope cutter 26 each exclusively in a direction extending in the machine direction L, led to the vertical plane.
  • the position of the Cable shears 26 can generally be changed in the machine running direction L.
  • the two ropes 18, 20 of the Rope guide 16 for positioning the rope shears 26 in the threading position E passed through the frame 30 of a web scanner 32 and then to release the web scanner 32 again withdrawn.
  • the cable shear 26 is thus between the Threading position E, in which the two cables 18, 20 of the cable guide 16 passed through the frame 30 of the web scanner 32 are adjustable, and a retracted position Z, in which the web scanner 32 is released again.
  • Their withdrawn Position Z rollers are shown in Figures 1 and 2 with 22 ' or 24 '.
  • FIG. 3 shows another in a simplified schematic representation Embodiment of the rope guide 16.
  • the cable guide 16 comprises one in the machine running direction L in front of a web scanner 30 guide section 36 and one in the web running direction L behind the web scanner 30 lying guide section 38. Between these two guide sections 36, 38 are the two ropes 18, 20 of the rope guide 16 from each other separately on opposite sides of the web scanner 32 led.
  • This cable shear 26 is in the present case for takeover of the web tip from the front guide section 36 the frame 30 of the web scanner 32 into a takeover position E and for transferring the material web into the rear Guide section 38 again in a behind the web scanner 32nd lying retracted position Z adjustable.
  • the two ropes 18, 20 can be used to form the rope shears 26 again Be guided over two rollers 22, 24, which via an adjusting device 28 (cf. in particular also FIGS. 1, 4 and 5) can be positioned accordingly are.
  • FIGS Figures 4 and 5 An exemplary embodiment of the adjusting device 28 is shown in FIGS Figures 4 and 5 shown.
  • the adjustment device comprises 28 a roller arrangement 40 with the two rollers 22, 24 which by means of a cylinder / piston unit 42 along a Guide rail 44 is movable.
  • the roller unit 40 is on runner 46 guided on the rail 44 is assigned.
  • a T-arm arrangement 48 is provided in the area of the roller arrangement 40 .
  • the cylinder / piston unit 42 engages with one connected to the roller arrangement 40 Hanging bracket 50.
  • the resulting one for the roller assembly 40 The stroke is indicated by h in FIG.
  • a nip protection 52 provided in the area of the roller arrangement 40 to recognize.
  • To limit the lifting movement of the roller assembly 40 can, for example, at least one proximity switch 54 or the like be provided.
