Definitions

  • the invention relates to a device for the form cutting of leading material webs, in particular of fiber materials, with a rotatingly driven form-cutting roller and a rotatingly driven counter-cutting roller, the form-cutting roller having a form-cutting edge and the counter-cutting roller having a smooth outer surface, both rollers being mounted on both sides in a machine frame by means of rotary bearings, and the Center distance of the rollers is adjustable.
  • Devices of this type are known for example from DE-A-39 24 053. With such devices, leading material webs made of fiber material, for example in the form of paper, nonwoven fabrics, textiles, but also plastic or metal foils and the like, can be cut, it being possible to produce curved cutting edges which are self-contained. Such devices are used in particular for the production of diaper pants, sanitary napkins and panty liners made of nonwoven fabric.
  • the form cutting edge arranged on the form cutting roller is pressed onto the smooth outer surface of the counter cutting roller during the cutting process pressed while the material web runs between the two rollers.
  • the object of the invention is to provide a device which eliminates the disadvantages mentioned by preventing parts of the form cutting edge from being broken out, thereby enabling a longer service life of the entire device.
  • the object is achieved in a generic device for shape cutting of leading material webs in that the rollers are rotatably mounted in separate, first and second machine frame parts, which in turn are supported on a common machine base part, that one of these machine frame parts for adjusting the center distance of the rollers on an adjustable Wedge guide is attached and that each machine frame part can be braced with the machine base part.
  • a preferred embodiment of a device 1 for the shape cutting of leading material webs from fiber materials comprises a rotationally driven shape cutting roller 2 and an oppositely driven counter-cutting roller 3 arranged with its axis parallel to the axis of the shape cutting roller 2.
  • the shape cutting roller 2 is to avoid lateral vibrations formed as a solid, compact shaft with a central area on which a protruding form cutting edge 4 is formed, and with shaft sections 2a and 2b arranged on both sides of the form cutting roller 4.
  • the central area of the lateral surface has a larger diameter than the shaft sections 2a and 2b.
  • the form cutting edge 4 can be curved and self-contained.
  • the counter-cutting roller which is also designed as a solid shaft, has a smooth, for example polished, outer surface 6 on.
  • the diameter of the lateral surface 6 is larger than the diameter of the shaft sections 3a and 3b adjoining on both sides of the lateral surface 6.
  • the counter-cutting roller 3 is conical on both sides of the lateral surface 6, the diameter of the shaft continuously decreasing from the value of the lateral surface 6 with increasing distance from the lateral surface 6 until it finally reaches the value of Diameter of the two shaft sections 3a, 3b.
  • the shaft sections 3a, 3b of the counter-cutting roller are each supported at the smallest possible distance from the lateral surface 6 in rotary bearings 7, which are fastened in a first machine frame part 8.
  • the form cutting roller is supported by means of its shaft sections 2a, 2b in rotary bearings 9, which are each arranged as close as possible to the form cutting edge 4 in a second machine frame part 11.
  • the rotary bearings 7 and 9 have a diameter which almost corresponds to the diameter of the counter-cutting roller 3 and the form-cutting roller 2, respectively. This enables the form cutting roller 2 and the counter cutting roller 3 to be securely supported and vibrations to be avoided.
  • the pivot bearings 7 and 9 are controllably coolable by a cooling device, not shown, known per se, so that a thermal expansion of the pivot bearings 7 and 9 and a thermal expansion of the cutting rollers 2, 3 and an associated disruptive change in position of the cutting edge 4 of the cutting roller 2 with respect to the lateral surface 6 of the counter-cutting roller 3 during the operation of the device 1 is avoided.
  • the rollers 2, 3 themselves can also be cooled in a controllable manner by the cooling device.
  • the first machine frame part 8 is bridge-shaped and firmly clamped to a machine frame part 12.
  • the bracing can be adjusted by means of screws 10 (FIG. 2) which protrude from below through the machine base part 12 and engage in a thread arranged in the first machine frame part 8.
  • the second machine frame part 11 is supported on a bridge 13 which overlaps the counter-cutting roller 3 and which, in turn, rests displaceably on a wedge guide 14.
  • the wedge guide 14 is supported on the machine base part 12.
  • the bridge 13 consists of two parts, preferably connected to one another, each of which a part overlaps a shaft section 3a, 3b of the counter-cutting roller 3 with play.
  • the wedge guide 14 comprises a first wedge-shaped part 16, which is horizontally displaceable on the machine base part 12, and a second wedge-shaped part 17, which lies with its tapered surface on the tapered surface of the first wedge-shaped part 16.
  • the bridge 13 rests on a substantially horizontal surface of the wedge-shaped part 17 opposite the beveled surface.
  • the first wedge-shaped part 16 is provided with an adjusting device 18.
  • the adjusting device 18 comprises a handwheel 19 which is attached to one end of a shaft 20.
  • the wedge guide 14 facing end of A shaft 21 is provided on this shaft 20.
  • the shaft 20 is rotatably held in a holder 22 which in turn is fastened on the machine base part 12.
  • a threaded bore 23 is arranged on the side facing the adjusting device 18, which matches the thread 21 of the shaft 20.
  • the thread 21 is screwed into or out of the threaded bore 23.
  • the shaft and the thread 21 are held stationary and immovably on the machine base part 12 by the holder 22, whereas the first wedge-shaped part 16 is horizontally displaceable on the machine base part 12, the wedge-shaped part moves when the handwheel 19 is turned 16 of the wedge guide 14 on the machine base part 12 horizontally - to the left or to the right in FIG. 1.
  • the tapered surface of the first wedge-shaped part 16 slides on the tapered surface of the second wedge-shaped part 17, whereby the second wedge-shaped part 17 within the first machine frame part 8 vertically, i.e. up or down.
  • the clamping device 24 comprises a yoke 26 connected to the machine base part 12 via supports 25 (FIG. 2). Threaded bores in the yoke 26 receive two screws 27 which are aligned with the pivot bearings 9 in the machine frame part 11.
  • the screws 27 have circular disk-shaped flanges 28 at their lower end, they are secured against self-loosening by lock nuts 29.
  • the circular disk-shaped flanges 28 of the screws 27 press on pressure beams 31, which in turn rest on the second machine frame part 11, cf. Fig. 2.
  • the second machine frame part 11 and the bridge 13 both around the rotary bearings 9 in the second machine frame part 11 and also about conical bores in the bridge 13, through which the counter-cutting roller, which is conical on both sides of its lateral surface 6 3 is passed through, in the pressure beams 31 and in the second machine frame part 11 with the pivot bearings 9 in the machine frame part 11 or with the bores in the bridge 13, columns 50 and 51 are aligned.
  • the gaps 50 and 51 enable the pressure beams 31 and the second machine frame part 11 to bend elastically, thereby preventing the pressure from being directly transmitted to the pivot bearings or the bores.
  • a hydraulic clamping device known per se can also be used, for example.
  • the pivot bearings 7, 9 are preloaded in a manner known per se, not shown in detail.
  • the rollers 2, 3 are driven by a belt drive 34.
  • the belt drive 34 essentially comprises a pulley 35 connected to the form-cutting roller 2, a pulley 36 connected to the counter-cutting roller, a deflection roller 37 and a tensioning roller 38 which is mounted on a pivotable lever 39 for adjusting the tension of the drive belt 40.
  • the lever 39 is adjusted by a double-acting piston-cylinder unit 30.
  • the drive belt 40 is guided over the pulley 35, the pulley 36, the deflection roller 37 and the tensioning roller 38 such that the counter-cutting roller 3 rotates in the opposite direction with respect to the form-cutting roller 2.
  • the drive is designed by appropriate dimensioning of the diameter of the disks 35, 36 so that the counter-cutting roller 3 is driven asynchronously to the form-cutting roller 2, so that the number of revolutions of the counter-cutting roller 3 is slightly less than that of the form-cutting roller 2. In this way, achieve even wear of the sensitive, usually polished, smooth outer surface of the counter-cutting roller 3 and thus increase its service life.
