Definitions

  • Sheeter for a web in particular corrugated board
  • the invention relates to a cross cutter for a web, in particular corrugated board web, with the features of the preamble of claim 1.
  • a cross cutter for web materials which has two knife bars arranged one above the other.
  • the upper cutter bar is driven at both ends by an electric motor.
  • the two cutter bars are mechanically connected on both sides by meshing gear pairs.
  • the meshing gears have helical gears.
  • a gearwheel of a gearwheel pair is displaceable. It is disadvantageous that the moments of inertia of all moving components, such as e.g. Electric motors, gear pairs and cutter bars are not minimized.
  • Only two drive motors are used for a cutter bar. These motors must supply the entire drive power for the cross cutter.
  • the meshing gears must be unnecessarily strong, which therefore have a high mass moment of inertia because the lower cutter bar must be driven with the appropriate torque.
  • the invention has for its object to provide a cross cutter, the cutter bars are driven exactly in synchronization, despite fluctuating rotational speed, the mass moments of inertia of all moving components are minimized.
  • each end of a pair of cutter bars is driven directly by a drive motor, the power to be applied by each motor and thus its size are reduced. In this way it is possible to provide a drive motor driving directly at each end of each knife bar. In addition, the mass moment of inertia of each drive motor is minimized. Since the meshing pairs of gearwheels no longer transmit any significant load on the ends of the cutter bars, they can be designed to be relatively weak. The moment of inertia, even of such weakly designed gears, is minimized.
  • the cutter bars are at least partially made of fiber composite material, preferably hollow. This minimizes the moment of inertia of the cutter bars, which reduces the performance of each motor.
  • At least one pair of gears is designed to be free of play. This ensures that the quality of the cut is guaranteed, because the cutters come into exact cut engagement one after the other.
  • Figure 1 is a schematic vertical section of a cross cutter for a web, preferably for a continuous corrugated cardboard web.
  • 2 shows an electrical block diagram for a control of the cross cutter drive for synchronism, speed and / or speed;
  • Fig. 3 is a block diagram of a modified version.
  • the cross cutter 1 has vertical, stable and parallel frame parts 2, 3 which rest on the floor 4.
  • cutter bars 5, 6 are rotatably supported by bearings 7.
  • the knife bars 5, 6 carry knives 8 running in their longitudinal direction, which are twisted with respect to the longitudinal axis.
  • the cutter bars 5, 6 are preferably hollow. They have stub axles 9 at their ends.
  • the cutter bars 5, 6 preferably consist predominantly of fiber composite material.
  • the stub axles 9 are made of metal.
  • a drive motor 10 is directly connected to the stub axles 9. However, the drive motors 10 can also be connected to the axle journals 9 via a coupling (not shown). The drive motors 10 are preferably electrical. But they could also be hydraulic.
  • the knife bars 5, 6 arranged one above the other form a pair of knife bars.
  • the cutter bars 5, 6 are arranged parallel to one another in the frame parts 2, 3.
  • Gears 11, 12 sit on the stub axles 9.
  • the upper gears 11 are divided. One gear part of each gear 11 is firmly seated on the stub axle 9, while the other gear part is arranged so as to be radially elastically rotatable.
  • These gears 11, 12 on each stub axle 9 mesh with one another.
  • the gear pairs are used for the mechanical drive connection the stub axles 9 of the upper and lower cutter bars 5, 6. Since they only have to take on a very low partial load for absolutely reliable synchronization, they can be made relatively thin.
  • the lower gearwheels 12 can of course also be divided and cooperate in a corresponding manner with the upper gearwheels 11.
  • the diameters of the cutter bars 5, 6 are determined so that their cutters 8 touch each other continuously and point-by-point as they pass through the material web to be cut transversely. Since the motors 10 only have to accept a reduced partial load at each end of a cutter bar 5, 6, because of their small size they can be arranged directly on each cutter bar 5, 6 at both ends. This minimizes the moments of inertia of the rotating masses of the drive motors and the gear wheels.
  • FIGS. 2 and 3 an electrical solution according to FIGS. 2 and 3 can also be provided.
  • the drive motors 10 are then electrically connected to a synchronization and speed control 13 via the lines 14. Inverters are used for this synchronization and / or speed control 13. Only one controller 13, as in FIG. 2, or two, as in FIG. 3, can be used. Control of the motors 10, as shown, is possible in pairs one above the other. The motors 10 could also be controlled side by side in pairs. Finally, individual control of the motors 10 is also conceivable.
