Definitions

  • the invention relates to a cutting knife for rotary cutting systems for paper, in particular multi-layer individual paper products with a round base body, from whose conical rear surface opposite the cutting plane adjustable blades or the like. stick out.
  • Such a cutting knife is known from DE-OS 37 19 721.
  • the individual blades are designed like a board and can be moved essentially radially or at an acute angle to the respective radial.
  • the wear of the blade which is made of specially hardened steel, it is possible to regrind the individual blades, the radius of the cutting knife remaining unchanged after grinding.
  • This known grinding knife has largely proven itself in practice.
  • the invention has for its object to provide a cutting knife of the type mentioned, which is provided with differently locked blades.
  • the object is achieved in that the blades or the like according to the invention. are locked adjustable about a pivot point.
  • the blades or the like. formed from discs with a round cut and adjustable in recesses in the base body held.
  • the blades or the like designed as a plate-shaped polygon and all sides have cutting surfaces; the blades or the like can be held adjustable either in round recesses or in polygonal recesses in the base body.
  • the procedure can expediently be such that the blades or the like. are only connected to the base body at their fulcrum and one additional hole each.
  • both fasteners are loosened, but only one fastener is loosened and reinserted at another point.
  • the blades or the like formed like a board, adjustable in approximately wedge-shaped recesses and connected to the base body at its hole-like pivot point and one additional hole each.
  • the base body or the like for adjustable locking of the board-like blades. each have part-circular recesses.
  • the blades or the like are. expediently covered on the conical rear surface, for example with a protective ring.
  • cover plates which are approximately horseshoe-shaped and assigned to the individual blades can also be provided. However, care should be taken that no cutting edge lying outside the actual cutting surface is exposed in any way.
  • the guard ring therefore has at least the width of the blades or the like. on.
  • the respective cutting surfaces of the blades or the like can be used. enclose an angle of 9 -12 °, preferably 8 °, with the respective tangent of the base body. In this case, however, the direction of rotation of the base body is fixed.
  • the latter can consist of a material that differs from the base body and a particularly hardened steel.
  • the cutting knife consists of a base body 1 and blades 2 which can be locked thereon.
  • Such cutting knives are used in rotary cutting systems, e.g. used for paper products or signatures in scale formation. These isolated paper products are held together on both sides of the cutting knife by press belts.
  • the base body 1 is provided with a central opening 3 for placement on a shaft. Furthermore, the base body has holes 4 for attachment to a holder. While the base body 1 is of equal thickness in its central area, its edges run from the edge 5 to be conical or approximately conical. Recesses 10 are provided within the conical edge, which are round in the present case and have approximately the depth of the blades 2 'designed as disks, each with a circular grinding 11. The blades are conical in cross-section and are on the one hand in their center by a bolt-like Connection to the base body 1 and on the other hand connected to a protective body 14 described in more detail.
  • each disc 2 has, in addition to the central bore 12, six further holes 15, which are evenly distributed over the circumference, but at a distance from the edge thereof.
  • the respective radially inner hole 15 takes a screw bolt or other connecting means and thus locks the disc 2' in the respective position.
  • the protective ring 14 is connected to the base body 1 by a further screw 16 and is otherwise not shown in FIGS. 1 to 6.
  • the discs 2 '- as well as all the other embodiments of the blades described below - are about 3-5 mm, preferably 4 mm, thick or thick.
  • the base body can have a diameter of 20-45 mm, the number of blades or disks being increased depending on the diameter thereof. It is also not necessary that between the off savings for the blades a greater distance 21 must be provided; rather, this distance can also be practically zero.
  • the embodiment of the cutting knife according to FIG. 1 can be used in both directions of rotation.
  • a hexagonal shape of the blade 2 ⁇ is provided; the respective cutting edges 30 are of equal length, the rear side of the disk 2 being conical in dashed lines in cross section, so that the one side which serves as the cutting edge has a e.g. occupies position shown in Fig. 2.
  • the recess 31 for receiving the hexagonal disc 2 ⁇ is adapted in the present case to the angular shape of the disc, so that when the disc 2 ⁇ is adjusted, it must be lifted out of the recess and brought into another cutting position.
  • the cutting plane 32 is also formed in all other embodiments by the end face of the cutting knife or base body 1 and continues flush through the conical design of the respective blade up to the actual free cutting edge.
  • FIGS. 1, 2 and the embodiment described below according to FIGS. 5 and 6 are generally used all around, i.e. regrinding of these blades is omitted, in the embodiments according to FIGS. 3 and 4 a board-like blade 40 and 41 is used provided the parallel side surfaces has and is also 3 - 5 mm, preferably 4 mm, thick.
  • the blades 40 and 41 must be reground after each adjustment.
  • the blade In Fig. 3 the blade is shown on the left in the initial position; it is held in a rounded slot via the pin 41 and rotates about the pivot pin 42 if an adjustment is made.
  • An adjustment in the direction of arrow 43 of the respective blade 40 is infinitely possible and can be adapted to the grinding requirements.
  • the blade 40 is adjustable in a wedge-shaped recess 45, the respective edges 46 and 47 of which limit the possibility of adjusting the blade 40.
  • the blade can be adjusted about a pivot pin 51 in the direction of the arrow 50, the second locking of the blade 41 via the hole 52 in a rounded slot 53 of the base body 1 being possible.
  • the recess 54 for the adjustable receiving of the blade 41 is adapted to the adjustment possibility, so that the free edge 55 of the recess runs obliquely, ie approximately wedge-shaped, and thus merges into a section 56 which extends approximately radially.
  • the opposite edges 57 and 58 of the recess 54 are formed accordingly.
  • the embodiment shown in Fig. 5 of the blades 2 and 3 ' is similar to the embodiment of Fig. 1, but with the individual cut edge portions are rounded outwards and thus result in a larger cutting surface.
  • the disk is 2 ⁇ ′ ground in each case so that an adjustment in the recess 60 is possible six times, that is, practically six cutting edges are provided.
  • the disc 2 ′′′ is locked on the one hand at the center of rotation 61 and then in each case via the one radially inner hole 62.
  • the free edge of the disc 65 is provided with asymmetrically shaped saw teeth 66; the cutting direction is indicated by arrow 67.
  • the cutting edge 66 lies in the plane 33 of the end face of the base body 1 and the disk 65 is each conical in cross section.
