Definitions

  • the invention relates to a foil knife for attachment to a knife roller according to the preamble of claim 1.
  • Such a foil knife is from the DE-U-298 05 004 known.
  • the foil cutter is provided with a plurality of through-holes in an arrangement corresponding to the positioning pins projecting radially on the cutter roller, into which the positioning pins engage when the foil cutter is placed on the cutter roller.
  • One of the through holes is formed as a circular bore, so that the foil knife can not be displaced in the axial direction of the knife roller when the positioning pins engage in the through holes.
  • a knife roller is also off DE 33 020 038 of the same applicant. It is used to cut out window openings in blanks of window envelopes.
  • a foil knife is clamped on the type of a printing plate on a punching roller and held purely mechanically.
  • the folded at its ends foil knife is mounted on its leading edge to a support member and clamped at its trailing end by means of holding and Sparinimplantationn and stretched.
  • These knives must always have a certain length between their fasteners and require precisely executed bends.
  • the clamping or changing a foil knife has a considerable amount of time.
  • foil knife is in this case set with a bent, front end by means of a terminal strip in a roll slot, while the remaining part of the foil knife is held by magnetic force on the periphery of a cup-shaped knife cylinder.
  • the production of roll slot and terminal strip as well as the fold of the foil knife require a high precision and workload.
  • the terminal strip must always be installed and removed with a blade change.
  • EP 0 312 422 B1 discloses a rotary cutter, in which a foil cutter for punching window openings is held only by magnetic force on the periphery of a cup-shaped knife cylinder.
  • the invention has for its object to make a foil knife for attachment to a knife roller, in particular for the production of envelopes, so that the foil knife quickly to change and positionable with sufficient accuracy and can be fixed.
  • the foil knives are quick and easy to change and position on the knife roller.
  • the foil blades are positively held by the engagement of the holding and positioning pins in the slots of the base plate and by magnetic holding forces on the peripheral surface of the knife roller. It is also advantageous that during the threading of the holding and positioning pins in the slots, the foil knife is axially parallel on the knife roller slidably. In conjunction with a slightly asymmetrical arrangement of the holding and positioning pins on a bar, a variable axis-parallel positioning of the foil cutter is possible.
  • a cutting station 1 for window letter covers a knife roller 2 and serving as a counter tool stationary cutting bar 3, between which a series of envelope blanks 4 or a letter envelope web is passed and processed.
  • the cutting bar 3 is clamped with a bar 6 mounted in a carrier 5 and along with this to the knife roller 2 back and away from this movable.
  • the cutting station 1a has a rotating counter-roller 3a as a counter-tool to the knife roller 2, between which a series of envelope blanks 4 or a letter envelope web is passed and processed.
  • the counter-roller 3a is mounted in a carrier, not shown, and is movable together with this to the knife roller 2 and away from it.
  • the Fig. 3 shows the knife roller 2, their storage and their essential parts in section, but without a foil knife and without serving for attaching and aligning a foil knife parts.
  • the knife roller 2 comprises a support shaft 14, which is mounted by means of ball bearings 15 in machine frames 16,18 and driven by a gear 17. Between the machine frames 16,18 a cylindrical roller body member 19 is rotatably mounted on the support shaft 14, on the circumference 20 of the suction openings 11 are arranged. In the roller body part 19, suction channels 21 are arranged parallel to the axis at a distance d from the axis of rotation 2 'of the knife roller 2 and are in air-conducting communication with the suction openings 11. On the front side on the roller body part 19, a suction air control valve 31 is arranged, which is mounted non-rotatably on the frame wall 18 by means of a spacer and centering bushing 32.
  • the Saug povertymaschineventil 31 has two separate, concentrically arranged Saugluftkanäle 39,40, which fresh air ducts 36,37 are arranged downstream.
  • the Saug povertykanäle 39,40 are connected via a Saug povertyzu operation 38 with a suction air source, not shown.
  • the suction air ducts 21 can be acted upon with suction air via the intake and transport angle range a or ⁇ .
  • a 3/3-way valve 41 in Roll body part 19 assigned. With a 3/3-way valve, a suction channel 21 is shut off or connectable via the through-bore 42 and 43 with the Saugluft horrkanal 39 and 40, respectively.
  • the suction air control including the 3/3-way valves is the subject of the parallel German application 198 41 834.5 of the same applicant.
  • the Saugluftkanälen 39 bzs. 40 is ever downstream of a fresh air duct 36 and 37, from where a reduction of the negative pressure in the suction channels 21 and the suction openings 11 takes place.
  • a foil knife 24 has a thin base plate 61 of magnetically permeable material having a thickness d 1 , and front and rear edges 62, 63 and side edges 64, 65. On the base plate 61 at least one integrally formed sharp cutting edge 28 is arranged, which forms a specific cutting shape.
  • the cutting edge 28 is designed to cut a window opening 8 'in a letter envelope blank 4, apertures 75 are arranged, which are in air-conducting connection with suction holes 11.
  • slots 68 are made in the base plate 61.
  • the slots 68 are arranged in alignment and have a width b, a length d 5 and a distance d 6 with each other.
  • the slots 68, the cutting edge 28 and also the front edge 62 have a predetermined fixed positional relationship to each other.
  • At least one row 76 holding and positioning pins 66 is arranged, which protrude radially with a height h from the peripheral surface 20, which corresponds approximately to the thickness d t of the base plate 61.
  • the holding and positioning pins 66 have a width b 1 and a distance d 2 with each other.
  • the width b 1 is dimensioned so that it corresponds to the slot width b.
  • a foil cutter 24 on the roll body part 19 this is hooked to the holding and positioning pin 66, so that the holding and positioning pins 66 protrude into the slots 68.
  • the foil cutter 24 is axially displaceable in the region of the slot length d 5 . Greater axial variations are achievable by translating the foil knife 24 in the row 74 of the retaining and locating pins 66.
  • the foil knife 24 is positively fixed by means of the holding and positioning pins 66 in the circumferential direction and by means of the magnetic elements frictionally on the roll body part, so that even with difficult cutting conditions, a displacement of the film knife 24 on the peripheral surface 20 does not take place.
  • FIG. 8-10 some form variants of the holding and positioning pins 66 are shown.
  • the holding and Positionicrzapfen 66 are integrally formed on a strip 27, the pseudo-accurate in an axis-parallel channel 25 of the roller body part 19 is arranged and fixed there by means of fastening elements 69.
  • the channel 25 At the end portions of the channel 25 are as Fig. 11 shows widening recesses 70 formed, open into the approximately radially aligned thread into which clamping screws 71 are screwed, which press with their heads 72 on the end of the strips 27 integrally formed shoulder surfaces 73 and so set the bar 27 in the channel 25.
  • the holding and positioning pins 66 to each other equal distances d 2 , to the shoulder surfaces 73, however, different end distances d 3 and d 4th
  • d 4 is larger by d 2/2 than d 3 .
  • the bar 27 is turnable in the channel 25 by 180 °.
  • a plurality of channels 25 are arranged distributed on the peripheral surface 20, in which, depending on Demand, depending on the number and size of the foil knife 2, strips 27 or only patches are arranged.
