Definitions

  • the invention is based on a cutting device for strips of material, such as paper or film tape for machine output with an electromechanical drive, with the features contained in the preamble of claim 1.
  • Such cutting devices for material strips and slightly helically twisted rotary knives and spring-loaded fixed knives according to DE-GM 87 16 108 are known.
  • the device consists of a profile body in an angular shape with an outer receiving trough for the rotary knife along one angle leg and a second angle leg as a base part for the motor mount at an angle between the two legs, the profile body being able to be cut to the desired passage width.
  • this cutting device intended for attachment or installation in corresponding devices, only full cuts of the continuous, e.g. printed material strips can be reached.
  • a cutting device which can also perform partial cuts.
  • lifting knives are used, which are actuated by means of a rocker arm with an upstream tooth segment, for which an electromagnet and a number of mechanical components are required, which represents a complex solution.
  • DE-A-24 39 560 a cutting device for material strips such as paper or film tape is known in machine output with an electromechanical drive and a twisted rotary knife and a fixed knife.
  • a gearbox with crank drive, a connecting rod with curve guidance and a drive crank are provided for driving the rotary knife.
  • a full or partial cut of the material strip can be adjusted via the curve guide by adjusting an adjusting screw via the drive crank of the rotary knife and its swivel axis.
  • DE-A-24 39 560 proposes an electromagnet with a core on which the set screw is arranged.
  • the cutting device is characterized in that the connecting rod in its bearing on the crank mechanism of the transmission by friction in the direction of rotation is lifted in a clockwise direction so that the drive crank on the rotary knife comes to rest in the cam leg in the direction of the connecting rod axis (aa) and causes a partial cut in the clockwise direction when the rotary knife has a shorter pivoting distance.
  • the drive crank of the rotary knife in the vertical cam leg causes a corresponding pivoting movement of the rotary knife clockwise for a full cut.
  • the cam guide has an angular shape at the drive end of the connecting rod for engaging the drive crank with a diameter and which can be changed in the direction of the connecting rod axis (a-a) by means of the adjusting screw, while the curve leg perpendicular to it widens slightly curved.
  • the cutting device for strips of material here paper strips 1, consists of the two side parts 2 and 3 with an intermediate, preferably sprung, fixed knife 4 and slightly twisted rotary knife 5 on the one hand and drive motor 6 with gear 7 and cover 8 on the other.
  • the rotary knife 5 is driven here from the transmission 7 via a crank drive 9, which drives a connecting rod 10 with cam guide 11, in which (11) a drive crank 12 of the rotary knife 5 engages.
  • the curve guide 11 has an angular shape, the cam leg lying in the direction of the connecting rod axis a-a being changeable by means of the adjusting screw 13, while the cam leg perpendicular to this extends at 14 slightly curved and the rear edge of which is somewhat curved.
  • FIGS. 3 and 5 with which the drive crank 12 on the rotary knife 5 engages in the curve leg in the direction of the connecting rod axis aa and, in the case of a shortened pivoting distance of the rotary knife 5 in the clockwise direction, causes only a partial cut.
  • the full or partial cut is thus dependent on the direction of rotation A or B of the crank mechanism 9 and thus of the drive motor 6, which (6) is controlled accordingly.
  • crank mechanism 9 The remaining distance that the crank mechanism 9 travels to the starting position brings the rotary knife 5 back into the rest position.
  • the cam 15 slides into the recess 16 and actuates the switch 17, which switches off the motor 6, so that the cutting device is again in the rest position.
  • the drive motor 6 is controlled so that the crank mechanism 9 rotates in the direction of arrow B.
  • the connecting rod 10 is raised by the friction, consisting of the spring 18 and the ball 20, so that the drive crank 12 of the rotary knife 5 comes to rest in the horizontal part of the curve guide 11 according to FIG. 5.
  • the rotary knife 5 rotates clockwise again.
  • the angle of rotation ⁇ is smaller than the angle ⁇ , due to the different position of the curve guide 11 with the shoulder 22 of the adjusting screw 13 in relation to the drive crank 12. Due to the reduced working stroke on the rotary knife 5, the paper strip 1 is only partially cut off.
  • the cutting width can be set within wide limits on the adjusting screw 13. In the borderline case, if the upper and lower part of the curve guide 11 lie on the same vertical plane without a shoulder, the motor 6 can make a complete cut in any direction of rotation.
  • the engine 6 is again switched off via the cams 15 and switches 17.
  • a connecting rod with a crank handle on the rotary knife is used to drive a gearbox with a crank mechanism, in such a way that a certain pivoting movement thereof is predetermined and the cutting width can be adjusted by turning the fixed knife.
  • the fixed knife can also serve as a paper guide part and preferably be sprung at 13, which results in an automatic readjustment.
