Definitions

  • the present invention relates to a method for keeping constant the marking line width at a standing under an injection pressure mark line color by means of at least one spray nozzle on a marking surface to be marked surface marking machines. Moreover, the invention relates to a marking machine for carrying out the method.
  • liquid, sprayable marking line colors are applied by high pressure or Airlessspritzspritz with movement of a marking machine in the longitudinal direction of the line to be marked surface.
  • the spray nozzles which can be used in the case of high-pressure spraying have the characteristic that when the ink flow rate changes, the pressure prevailing upstream changes slightly and slightly, but noticeably, the spray width of the triangular spray fan also changes, and the spray width increases with increasing pressure.
  • the object of the invention is to overcome the above-mentioned deficiencies and to abolish or at least reduce the influence of the marking speed on the generated marking line width to a non-disturbing degree.
  • the solution of the part of the object relating to the method succeeds according to the invention with a method of the type mentioned above, which is characterized in that the position of the spray nozzle with respect to the surface to be marked by means of the injection pressure or a pressure of another fluid dependent on the injection pressure the marking line width is controlled to be kept constant during injection pressure changes.
  • the injection pressure of the ink or a different pressure dependent thereon is used to control the position of the spray nozzle or of a spray gun having this relative to the surface to be marked in such a way that the injection pressure changes with the marking speed and thus with the flow rate which remains the same on the surface to be marked spray width remains the same.
  • the marking lines are always generated with the desired constant line width regardless of the marking speed.
  • a first embodiment provides that a distance of the spray nozzle is controlled to the surface to be marked.
  • a reduction of the distance leads to a smaller line width because of the widening with increasing distance, triangular spray fan, an increase of the distance increases the line width of the marking line.
  • a rotational position of the spray nozzle can be controlled about a substantially vertical axis relative to the surface to be marked.
  • a rotational position of the paint sprayer In a rotational position of the paint sprayer exactly transverse to the longitudinal direction of the marking line results in a maximum line width. Twisting the nozzle and the paint spray fan generated by it from this position leads to a reduction in the line width.
  • this method has the small disadvantage that the beginnings and ends of the marking line may have a more or less oblique course to the transverse direction of the marking line.
  • a rotational position of the spray nozzle is controlled about an axis extending substantially horizontally and transversely to the longitudinal direction of the marking line relative to the surface to be marked.
  • the marker line color is sprayed more or less steeply on the surface to be marked, whereby the distance from the nozzle to the surface and thus because of the widening with increasing distance, triangular spray fan and the marking line width can be varied.
  • the injection pressure or the pressure of the other fluid, which is dependent on the injection pressure is to act on a piston-cylinder unit which changes the position of the spray nozzle with respect to the surface to be marked and counteracts a restoring force.
  • the spray nozzle is adjusted in position until the force of the piston-cylinder unit is in equilibrium with the restoring force.
  • the spray nozzle is adjusted in position until the force of the piston-cylinder unit is in equilibrium with the restoring force.
  • the spray width change in relation to the desired spray width and thus the required adjustment of the spray nozzle is not only dependent on the injection pressure change, but often also dependent on the geometry of the spray nozzle and the marker line colors used. This means that the ratio of required adjustment of the spray nozzle for injection pressure change for different spray nozzles and colors varies in size and should therefore be changeable.
  • the invention therefore proposes that the force of the piston-cylinder unit and / or the restoring force be varied depending on the geometry of different spray nozzles and / or the properties of different marking line colors and set to desired values.
  • the restoring force is preferably generated by at least one spring.
  • the other fluid is a hydraulic fluid serving as drive fluid of a hydraulically driven pump for conveying the marker line color.
  • This hydraulic fluid can be readily fed directly to the piston-cylinder unit as pressurized fluid without any fear of malfunctions that could occur if the marking line color itself were supplied as pressure fluid to the piston-cylinder unit.
  • An alternative embodiment of the method proposes that the injection pressure or the pressure dependent on the injection pressure of the other fluid is detected by at least one pressure sensor and transmitted to an electrical or electronic control unit and that the control unit a the position of the spray nozzle with respect to the Surface-changing electrical or electronic adjusting device adjusted pressure-dependent.
  • the implementation of the change in the injection pressure in a change in position of the spray nozzle or gun is carried out here using electrical and / or electronic aids.
  • the solution of the marking machine of the part of the task succeeds according to the invention with a marking machine for the production of marking lines by spraying under a spray pressure mark line color by means of at least one spray nozzle on a surface to be marked, which is characterized in that the spray nozzle or a spray gun having them at a position in relation to the surface to be marked in dependence on the injection pressure or by a pressure of another fluid dependent on the injection pressure of the marking line width at injection pressure changes constantly holding adjustable mount is attached.
  • the method according to the invention can be carried out more economically and marking lines of constant line width can be produced, in particular at a high and / or changing marking speed.
  • the holder can be at a distance from the surface to be marked and / or at a substantially vertical axis relative to the surface to be marked and / or at an axis substantially horizontal and transverse to the longitudinal direction of the marking line relative to the axis be adjustable marking surface.
  • the width of the marking line generated by the paint spray fan emerging from the spray nozzle can be changed.
  • the holder is acted upon by a restoring force acting in the direction of increasing the width of the marking line, and the holder is counter to the restoring force by means of a piston-cylinder unit which can be acted upon by the injection pressure or by the pressure of the other fluid dependent on the injection pressure adjustable in the direction of a reduction of the width of the marking line.
  • the machine is technically simple and thereby cost-effectively manufactured and operable despite the improved function.
  • the effect of the force of the piston-cylinder unit and / or the restoring force is suitably variable depending on the geometry of different spray nozzles and / or the properties of different marker line colors and adjustable to desired values in order to compensate for these further influences on the spray width can ,
  • the restoring force is preferably generated by at least one spring, since this is a cost-effective and reliable component.
  • a technically favorable way of changing the above-mentioned force action is to change lever lengths.
  • the holder has a coupling lever arrangement connected to the spring and to the piston-cylinder unit and that the spring and / or the piston-cylinder unit can be changed in their connection position to the coupling lever arrangement.
  • the leverage ratios of said variable coupling lever assembly and also the piston surface of the piston-cylinder unit and the spring must be designed so that the spray nozzle is adjusted in position relative to the surface to be marked in a manner and to the extent necessary to compensate for the change in spray width and mark line width change occurring without adjustment of the spray nozzle.
  • the spray width change in relation to the desired spray width and thus the required adjustment of the spray nozzle is dependent on the spray pressure change, the geometry of the spray nozzle and the color used.
  • the invention provides that the marking machine has at least one hydraulically driven pump for conveying the marking line color and that the other fluid is a hydraulic fluid, which serves as a drive fluid of a hydraulic motor of the pump.
  • the pressure fluid used anyway for the ink pump drive is also used for the operation of the piston-cylinder unit for the spray nozzle adjustment, which keeps the machine technically simple.
  • An alternative embodiment of the marking machine provides that it has at least one of the injection pressure or the pressure of the injection of the other fluid pressure sensor which is connected to an input of an electric or electronic control unit, and that with the control unit, a position of the holder connected in relation to the surface to be marked pressure-dependent changing electrical or electronic control device.
  • the actuator may here be e.g. an electrically driven adjusting spindle or an electric stepping motor, which can be operated in accordance with the pressure measurement values of the pressure sensor via the control unit that evaluates this.
  • Such a control unit can also be connected to an optical width measuring device for the continuous detection of the width of the generated marking line and for the detection and correction of possibly occurring width changes.
  • a marking machine 1 is equipped with a paint pump 2, which is driven by a hydraulic motor 3 via a connecting shaft 4 and promotes the marking line color via a line 16 to a spray gun 5 with spray nozzle 6.
  • the spray nozzle 6 generates a spray fan 15 from the marking line color, whereby a marking line 14 'is generated when moving the marking machine 1 in the direction of movement 18 on a surface 14 to be marked.
  • a change in the pump delivery rate has a change in the injection pressure, with unchanged geometry of the spray nozzle 6, i. the pump delivery pressure and thus directly dependent also on a line 7 to the hydraulic motor 3 supplied hydraulic oil result, and that these pressures increase with increasing ink flow.
  • FIG. 2 the spraying fan emerging from the spray nozzle 6 is shown, once marked with 15 for lower injection pressure with a smaller opening angle and 15 'for larger injection pressure with a larger opening angle.
  • the spray nozzle 6 is lowered at the larger injection pressure to a displacement path s with respect to the nozzle position at lower injection pressure to achieve the same width B of the marking line 14 'on the surface 14 to be marked as at at a larger injection pressure and thus larger opening angle of the spray fan the lower injection pressure.
  • the spray gun 5 is fixed to a bracket 8 with a vertical support, the two coupling levers 9 and 10 on a support 12th is articulated vertically displaceable in a parallelogram.
  • the carrier 12 is rigidly connected to a vehicle 11 which carries the marking machine 1.
