Definitions

  • the invention relates to a device for cutting individual cards from continuous card material with a fixed lower knife and a longitudinally movable upper knife relative to it, which is driven by a motor via an eccentric, the upper knife being formed on both sides of the cutting edge with excellent guide tongues, which also in the rear end position of the upper knife rest on the lower knife.
  • Such devices are particularly known in the case of dispensers for prepaid cards (e.g. US-A-4823663).
  • dispensers for prepaid cards e.g. US-A-4823663.
  • the invention has for its object to provide a particularly space-saving and reliable storage and guidance for the upper knife of a device of the type described above.
  • the solution to this problem by the invention is characterized in that the upper knife is provided with longitudinal grooves parallel to the direction of movement, in each of which a guide collar of a bearing roller engages, that three bearing rollers engage on the longitudinal grooves on each longitudinal side of the upper knife, two of which engage on the drive side End of the upper knife on the top and bottom opposite and a bearing roller is designed as a hold-down and the upper knife leads to the lower knife.
  • the inventive design of the upper knife and the bearing rollers leading and guiding the bearing rollers results in a simple design good guidance of the upper knife both in the longitudinal and in the transverse direction and also high efficiency, since the entire energy of the drive motor with the exception of very low friction losses in cutting force is implemented. While the previous friction destroyed almost 50% of the energy of the drive motor, in the embodiment according to the invention only about 5% of the drive power is due to friction losses on the one hand between the upper knife and the lower knife and on the other hand between the guide collar of the bearing rollers and the longitudinal grooves in the upper knife.
  • there is a particularly space-saving design which enables the device according to the invention to be used even in confined spaces.
  • the bearing rollers provided with a guide collar commercially available ball bearings with an attached flange can be used according to the invention, so that the device according to the invention can be manufactured inexpensively.
  • the upper knife can be formed with a transverse elongated hole in which the eccentric of the knife drive provided with a ball bearing engages. This also results in rolling friction only for the drive of the upper knife, so that energy losses are avoided to this extent.
  • the invention proposes to design the cutting edge of the upper knife in a V-shape and symmetrically to the longitudinal center. This prevents lateral displacement forces on the upper knife and its guidance from occurring during the cut; in addition, the upper knife designed in this way manages with a shorter stroke, which at the same time makes it possible to reduce the drive speed.
  • the dispenser shown schematically in FIG. 1 is used for dispensing value cards which, in the exemplary embodiment, are separated from continuous material with a cutting device, which is fed to the cutting device through a respective feed shaft 1 by means of a pair of drive rollers 2. At the point where the three feed shafts 1 meet, a further pair of drive rollers 3 is arranged in the embodiment.
  • a sensor system 4 is provided which detects the respective interface on the continuous material and controls the drive roller pairs 2 in such a way that the cut to be produced by the cutting device takes place at the respectively provided location.
  • the cutting device comprises a fixed lower knife 5 and an upper knife 6 which is guided in a longitudinally movable manner and in the exemplary embodiment is driven by a motor 7 designed as a stepping motor. On the shaft of this motor 7, an eccentric 8 is attached, which carries a ball bearing 9, which cooperates with the upper knife 6.
  • the upper knife 6 is provided with a transverse slot 10 into which the ball bearing 9 engages. In this way, one revolution of the shaft of the motor 7 results in a reciprocating movement of the upper knife 6.
  • the upper knife 6 is provided with longitudinal grooves 11 which are parallel to the direction of movement and which can either be formed as depressions in the top and bottom of the upper knife 6 or as continuous slots.
  • the opposite end, provided with a cutting edge 13, of the upper knife 6 is guided by two further bearing rollers 12 acting on its upper side in such a way that it cooperates reliably with the fixed lower knife 5.
  • the upper knife 6 is formed on both sides of the cutting edge 13 with guide tongues 14 projecting therefrom, which can best be seen in FIG. 2 are.
  • Fig. 2 also shows the V-shaped design of the cutting edge 13. In this way, with the simultaneous shortening of the necessary stroke of the upper knife 6, it is achieved that no lateral forces are exerted on the upper knife 6 when the cutting operation is carried out, since the transverse components of the cutting forces are different cancel each other by the V-shaped and symmetrical design of the cutting edge 13.
  • the section separated from the continuous material (not shown) by means of the cutting device described above is gripped by a pair of drive rollers 15 which are located above the cutting device and feed the cut card material to an output shaft 16.
