Definitions

  • the invention relates to a knife roller for processing and in particular for cutting paper in the manufacture of blank envelopes for mailing bags, envelopes and the like the features of the preamble of claim 1.
  • Knife rollers of the type of interest here arranged on the roller circumference Knives in particular in the form of foil knives for example for punching out window openings in envelope blanks serve and by means of magnetic force on the roller body are known from EP 0 312 422 B1. Also describes DE 198 41 834.5 a knife roller with a foil knife for cutting paper, the foil knife with a beveled, front end using a terminal block in one Roll slot is fixed while the rest of the foil knife is held with magnetic force on the circumference of the roller body.
  • a Similar device is from German patent application DE 199 25 612.8 known, but with the front edge of the foil knife Has slots and is suspended in pins arranged on the roller.
  • the invention is therefore based on the problem of measures create that allow depending on any knife contour, the narrowest possible hole pattern for the suction air Provide suction openings.
  • At least one as a holding magnet Serving magnet is provided for the or the foil knife has at least one suction opening for suction air, the suction opening with at least one radial bore in the Knife roller is in an air-conducting connection.
  • the position of the suction openings in the magnets can also be used to the respective shape and shape of the foil knife and / or each parts to be separated are adjusted. This has the consequence that an operation of the cutting station with the highest possible speed of the knife roller and thus the production machine is also possible.
  • the Management and handling of the paper blanks, the paper web or the of each waste can be precisely controlled, because according to the invention attack the suction air at precisely defined points to let. So there is also the possibility of extremely complicated To provide cuts that are much more complex and difficult are to be carried out as, for example, the production of simple window openings for envelopes.
  • a cutting station 7 with a knife roller 8 required (Fig. 1). With their help, parts from the Material of the envelope blank 3 cut out or punched out.
  • the Cutting station 7 a counter tool working with the knife roller 8 9, which is mounted in a carrier 10.
  • Envelope blanks 3 or an envelope sheet are between the knife roller 8th and passed through the counter tool 9 and processed.
  • the envelope blank 3 or the envelope cover are from the knife roller 8 gripped and along a circular path under the counter tool 9 passed through, the window opening 4 or any other Openings 5 are cut out.
  • the knife roller 8 On its circumference 12 a plurality of rows 13 (rows of suction holes 13) arranged suction openings 14.
  • the envelope blank 3 will over a suction and transport angle range ⁇ by means of suction air the knife roller 8 held and then transferred to a roller 15.
  • the piece of material or the punched out part 11 is by means of suction air initially still in the contour of the window opening 4 Knife edge or held in the contour of the window knife periphery and after a suction and transport angle range ⁇ into one Suction funnel 16 delivered.
  • the knife roller 8 comprises a carrier shaft 17, which with the help of ball bearings stored in a machine frame and by means of a gear 18 can be driven. It also includes a roller body 19 the circumference 12 of the suction openings 14 arranged in rows 13 lie. In the roller body 19 there are also axially parallel Suction channels 20, which are air-conducting with the suction openings 14 Connect. At the end of the roller body 19 is a suction air control valve 21 arranged, which in a generally known manner (DE 198 41 834 A1) in the sow channels 20 and thus on the associated Suction openings 14 via connecting radial bores 22 either Vacuum or atmospheric pressure generated. It's either here Negative pressure, atomic pressure or positive pressure (when repelling the Novaschnippels).
  • FIG. 2 shows that suction openings 14 immediately are located in the roller body 19.
  • a magnet 23 with four suction openings 14 'and correspondingly four Through openings 24 are shown in three views in FIG. 11.
  • This Magnet 23 is rod-shaped and expediently a permanent magnet. For example, it has a rectangular cross section. According to The suction openings 14 'are symmetrical in the exemplary embodiment Magnet 23 arranged. They lie essentially in its central axis 23 '.
  • the magnets are in recesses 25 with adapted to the magnets Cross section arranged on the circumference 12 of the knife roller 8. According to the embodiment shown in FIGS. 2 and 3 extend the recesses 25, in which one or more magnets 23 can lie, in each case in the longitudinal direction of the knife roller 8. Between them are roller webs 26, as shown in Fig. 2 and in the settlement according to FIG. 3 is shown.
  • the representation of the circumference 12 of the knife roller developed in the plane 8 schematically shows, according to FIG. 3, the contour 30 of a blank envelope 3 and a foil knife 31 with a knife edge 32.
  • the shape and shape of the knife edge 32 is used for cutting out / Punch out a window opening 4 in the envelope blank Third
  • FIG. 3 are the suction openings 14 in the transport direction first row of suction holes 13 in a roller web 26 of the knife roller 8th.
  • each a plurality of magnets 23 fit into each of the recesses 25.
  • the magnets 23 are used to attach the magnetically fixable Material of existing foil knife 31.
  • the exact location of the foil knife 31 is arranged with the help of rollers Pins 33 and slots 34 provided on the knife side achieved.
  • openings 35 for suction air there are also openings 35 for suction air. They cover at least partially and at least one Row of suction holes 13 so that suction openings 14 in a roller web 26 or suction openings 14 'in magnets 23 in the region of the openings 35 lie.
  • suction openings located within the contour of the knife edge 32 14 and 14 'serve to hold the punched or cut Piece of material or part 11 until this in the suction funnel 16 is delivered.
  • the recesses 25 do not necessarily have to be in Extend the longitudinal direction of the knife roller 8. You can basically also arranged like an annular groove in the circumferential direction of the knife roller his. Different installation options as well as different designs Magnets including different arrangements of the suction openings 14 in the magnets and / or in the roller webs or on the circumference 12 of the knife roller 8 are shown in FIGS. 4 to 12. in principle same parts in each of these embodiments the same reference numbers and additionally different letter indices on.
  • Suction openings 14 and 14 ' may be arranged symmetrically. Your location can also be asymmetrical, as shown in FIG. 4.
  • the suction openings 14a are located off-center in the roller webs 26a the knife roller 8a (Fig. 4). Basically the same applies to the Suction openings 14a 'in the magnets 23a.
  • the suction openings 14a and 14a ' also do not have to have a cross section mandatory circular, but they can also be semi-circular and / or be in the form of a segment of a circle. After all, this means that a Suction opening 14a arranged in such a way in the edge of a roller web 26 can be that it is open to the magnet 23a. On the other hand, can also a through-opening leading an axial bore / suction channel 20 be arranged at the edge such that they face the magnetic edge 38a is open. Basically, therefore, suction openings 14a in the Roller web 26a and suction openings 14a 'are located in magnets 23a in such a way that they together result in a suction opening (Fig. 4). Understands it is also certain that these suction openings in whole or in part are aligned with radial bores 22a in the knife roller 8a (FIG. 8).
  • the magnets 23 and 23a do not necessarily have to be straight be and also the associated recesses 25 and 25a must do not necessarily extend in the longitudinal direction of the knife roller 8 or 8a, but magnets 23b can also be designed in an arc shape be and the recesses 25b and the associated, adjacent Webs 26b can also extend in the circumferential direction of the knife roller 8b extend (Fig. 12 and Fig. 5 and Fig. 9). Here too they can Suction openings 14b 'arranged symmetrically in the magnets 23b his.
  • the passage openings 24b are symmetrical in the arcuate magnet 23b, as shown in FIGS. 5 and 12.
  • suction openings 14c ' can also be off-center or asymmetrical in the arcuate magnets 23c and / or in the circumferentially extending roll webs 26c according to FIGS Representations in FIGS. 6 and 10 may be arranged.
  • the basic principle here applies again the same as that shown in FIGS. 4 and 8 Knife roller 8a (Fig. 4).
