Definitions

  • the arrangement relates to the control of a cutting device.
  • a cutting device is provided which separates the printed part from the supply.
  • Such a cutting device is usually operated by a motor and controlled by the control, which also acts on the paper transport. Position switches must be provided and connected to the control so that the paper knife executes the desired movement exactly. In particular, it is desirable to be able to carry out a complete cut as well as a cut in which a small cut length remains uncut by reducing the depth of cut.
  • a solution to this is shown in DE PS 43 15 507 C1, in which a curved path moves the knife and mechanical means are used to switch between full and first cut.
  • a cutting knife driven by a direct current motor is shown, in which the depth of movement for a cut with a tear-off residue is determined by an additional (to be adjusted) sensor.
  • the object of the invention is to provide a cutting device in which, for each cut, a fully permanent section or one with demolition residue can be selected without the need for a position sensor.
  • the invention uses a stepper motor which transmits its rotary movement into a linear movement on the knife by means of a worm, an intermediate wheel and a toothed rack.
  • a digital control uses the number of steps to control whether a full cut or a cut is carried out.
  • the preferred embodiment does not require any mechanical adjustment and without any position indicator, so that the drive is considerably simplified.
  • FIG. 1 shows a schematic illustration of a cutting device with a stepping motor
  • Fig. 3 shows an alternative drive with a steel belt.
  • the cutting device consists of a carriage 6, which is mounted in a known manner on a fixed housing part 5 in the direction of arrow A slidably.
  • the carriage carries a cutting knife 7, which can separate the paper web when moving in the direction of arrow A by means of a counter knife 8.
  • a toothed rack 9 is fastened to the other end of the slide and is moved via a segment gearwheel 10 by a worm wheel 11 driven directly by a stepping motor 12.
  • the toothed rack, the toothed wheel, the worm wheel and the stepping motor are preferably designed such that the knife completely cuts the paper web in about 90 steps.
  • a knife 7 according to FIG. 2 is used with cut edges which are oblique to the edge of the counter knife 8 and arranged in a V-shape relative to one another, then a smaller number of steps, e.g. An initial cut is carried out in 75 steps, in which a small tear-off bar in the middle is not severed. The difference between full cut and first cut therefore only requires a different number of steps and no additional position indicators that have to be adjusted.
  • the knife 7 can also be provided with a single cutting edge positioned obliquely to the edge of the counter knife 8. The tear-off web then forms on a side edge of the paper web.
  • the adjustment is made in that, for example, a wall in the housing part 5 forms a stop 13 in the removed state of the knife.
  • the control moves the slide into the opposite position with a number of steps that are above the number required for a full cut, in the example 120 steps.
  • the carriage is prevented from moving by the stop 13, so that the stepper motor loses steps, but afterwards in a known manner Position is.
  • the stepper motor is then expediently moved a small number of steps out of the adjustment position in order not to drive against the stop with each cut.
  • the position of the stop only needs to be determined precisely within the usual manufacturing tolerances and not to be mechanically adjusted. Rather, a number of test cuts are carried out in which the number of steps is varied. The optimal number of steps is then recorded in a non-volatile memory of the control. Alternatively, of course, a predetermined number of steps can also be used and a known mechanical adjusting screw can be used as the stop 13.
  • the drive shown with worm wheel, segment gear and rack has the advantage that the stepper motor can deliver a pushing force with high mechanical efficiency, so that motor, slide and knife can be arranged in one unit on the same side of the paper web, - with a drive through In the rest position, the knife and drive would have to be on different sides of the paper web.
  • the motor is arranged perpendicular to the direction of movement of the slide and therefore does not contribute to increasing the overall height.
  • a threaded spindle on the motor axis can also engage directly in a spindle nut in the slide 6 or on an attachment which is fastened on the slide 6.
  • a drive can also take place via a steel belt 31, which, as shown in FIG. 3, is wound onto a wheel 32 or can unwind from it.
  • the engine can only exert a pull, the opposite direction is carried out by a compression spring 33.
  • the stepper motor since it also has to tension the spring 33, has to use twice the torque compared to the arrangement with worm and rack, which is offset by the better mechanical efficiency.
  • a cam disc can also be used on a stepper motor with a high number of steps per revolution. Incremental numbers of 200 per revolution are readily available, even with small motor designs.
  • the cam disc either exerts only pressure in one direction against a spring, or it is designed as a link wheel in which a driver engages on the carriage.
  • a steel cable and a cable pulley which is preferably wrapped around a plurality of times, on the axis of the stepping motor and at least one deflecting pulley, so that the stepping motor can exert a pull in both directions of rotation on the slide in opposite directions, the necessary tension spring is attached to the leading edge of the knife in the return direction.
  • the tension spring is force-neutral, so that, as in the preferred drive with worm, gear and rack, only the simple pushing force has to be applied by the stepper motor. Since frequent calibration by the stop is possible without any problems, a slight or occasional slip on the rope pulley does not have any significant effect.
  • the number of steps for a step can also be extended with the number of cuts after a calibration according to an empirically or theoretically determined extension factor, without a calibration being necessary for each cut. dig that often causes increased operating noise due to the loss of step in the stepper motor.
  • This extension factor is practically achieved by inserting an additional 5 step in the cutting direction after a predetermined number of cuts.
  • the controller can count the number of Schnit ⁇ th and kompensie ⁇ ren wear of the cutting knife by a slightly elongated cutting motion. This is in the previously known solutions when 0 at all directions only by expensive zustatzliche Versmaschinein ⁇ possible.
