Definitions

  • the invention relates to a cutting device for band-shaped materials, which an electromotive drive for driving a slidably mounted Has flat knife and a fixed knife, the slidably mounted Flat knife is laterally stored in a bearing element and that slidable flat knife essentially over its cutting edge attaches to the cutting edge of the fixed knife, so that this results in a three-point bearing of the flat knife can be formed, and that the slidably mounted Flat knife over two essentially symmetrical to the direction of movement of the flat knife running center line arranged drive points can be driven is.
  • Such a cutting device has been proposed in WO 94/26478 (EP-A 0 693 939), prior art according to Art 54 (3) EPC, and z. B. for cutting paper tapes, such as. B. in printers or Card machines are used.
  • EP-A 0 519 102 describes a device for cutting off individual cards of continuous card material with a fixed bottom knife and a relative for this purpose longitudinally guided upper knife that from an engine over a Eccentric is known.
  • the upper knife is used to create guidance and storage of the upper knife longitudinal grooves parallel to the direction of movement, into each of which a guide point a bearing roller engages.
  • On each long side of the upper knife attack three such bearing rollers, two of which are on the drive side End of the upper knife on the top and bottom opposite and one Bearing roller is designed as a hold-down device and the upper knife defines the lower knife leads.
  • the upper knife is on both sides of the cutting edge with over these excellent Guide zones formed, which also in the rear end position of the upper knife rest on the lower knife.
  • From DE-A 40 20 630 is a cutting device for coverings, journal rolls and the like, in which a movable knife on a fixed Knife bar slides past, the movable knife with the drive connected is.
  • the movable knife is mounted on a carrier part. It there are two eccentrically symmetrical support points on which the movable knife rests elastically, with the movable knife in the middle between the support points in the cutting direction and as a three-point bearing is supported.
  • a cutting device described in DE-OS 35 07 620 works with a fixed cutting edge and a longitudinally movable flat knife, which is stored on a fixed carrier. This creates high Frictional forces that are overcome by the drive of the cutting device have to.
  • the flat knife has a V-shaped cutting edge in plan view and seen in section is slightly roof-shaped.
  • the flat knife is under tension pressed against the fixed knife, taking the necessary counterforce can be included in side sliding guides.
  • Such a construction has the disadvantage that friction forces in the side guides arise, which are overcome by the drive of the cutting device have to.
  • the cutting device is subject to high wear. Lubrication in the side guides Sliding knife is only possible to a limited extent because - predominantly when cutting paper-like tapes - the resulting dust on would set lubricant.
  • the flat knife driving drive part via essentially symmetrically arranged drive levers is connected to the points of attack of the flat knife that the on Flat knife attacking first drive lever at its drive end is connected to the drive and a toothing at its output end has, and that the second drive lever at its drive end another interacting with the toothing of the first output lever Has teeth and at its output end with a pin is connected to the second point of attack of the flat knife.
  • FIG. 1 to 4 is a first embodiment of a cutting device 1, which shows a drive unit accommodated in a housing 2 Flat knife 14, which consists essentially of a drive motor 3 Worm 4 and a worm wheel 5 with a drive pin 6 there.
  • the Drive pin 6 engages in an arranged in the drive end of a connecting rod 8 angular recess 7 a.

  • the two pins 12, 12a engage in corresponding openings 13, 13a of the flat knife 14 and thus form essentially symmetrical to the center line of the flat knife 14 arranged drive points for the flat knife 14 out.
  • the provided for the cutting device 1 symmetrical drive of the Flat knife 14 over the essentially symmetrically arranged to each other Drive lever 9, 9a has the advantage that in the cutting process in advantageously, asymmetrical tilting forces cannot occur.
  • the flat knife 14 is - as best seen in FIG. 3 rotated by 90 ° can be seen from Figure 4 - in two laterally arranged notches 21, 21a stored on balls 17-20.
  • This ball bearing of the flat knife 14 in The notches 21, 21a has the advantage of being particularly low-friction Guide.
  • the flat knife 14 of the cutting device 1 slides in the cutting process only with its cutting edge 15 via a with the flat knife 14 cooperating fixed knife 16, so that even in this area a particularly low level of friction is achieved.
  • the bearing balls 17-20 in the notches 21, 21a fixed in such a way that the flat knife 14 is formed with a pretension is.
  • the three-point support of the flat knife 14 by means of the side arranged notches 21, 21a with bearing balls 17-20 and the leadership of Flat knife 14 along its cutting edge 15 over the fixed knife 16 is the formed by the flat knife 14 and the fixed knife 16 Knife group arrangement statically stable in an advantageous manner.
  • the bias of the flat knife 14 in the cutting device 1 ensures an exact system on the fixed knife 16.
  • the knife can also be stored according to the example of Figures 6 and 7 (claims 3-5).
  • the cutting device 1 described is also characterized by that in a particularly simple manner both a full cut and can make a partial cut:
  • Connecting rod 8 is achieved in an advantageous manner that in one revolution of the worm wheel 5 in a direction of rotation running clockwise in FIG the drive pin 6 in the shallower recess 7 'of the two recesses 7 ', 7 "of the recess 7 engages so that the flat knife 14 then preferably executes the maximum possible stroke, so that the one to be separated Tape is cut off completely.
  • FIGS. 5 to 7 now show an example of a cutting device 100 shown.
  • a geared motor 23 is attached, which via a toothed belt 24th Drive wheels 25 and 25a drives, the drive pins 28, 28a, which engage in the connecting rods 29 and 29a, which in turn are articulated with bolts 10, 10a Levers 30, 30a are connected, which correspond to a flat knife 14 Attack flat knife 32 via connecting bolts 31, 31a.
