Definitions

  • the invention relates to a method and apparatus for producing or renewing horizontal markings on roads, in particular limiting, guidance and warning lines, wherein a marking machine, the at least one spray gun for a liquid marker and an injection device for introducing profile particles directly into the Spray jet of liquid Markungsstopes has a color trace is applied to the road surface.
  • Such a method and a marking vehicle, which is still equipped with a further arranged in the direction of travel downstream spreader are through the EP 0 280 102 A1 known.
  • the injection device mounted in the immediate vicinity of the paint spray gun is directed at the slightly inclined jet of ink so that the profile particles enter the sprayed liquid marker before the jet hits the road surface.
  • aqueous marking compositions can be removed with a filler consisting of glass beads, for example.
  • the injection device also called "bead gun” for injecting beads or other co-formulants into the spray steel of the liquid marker delivers a certain amount of beads or coats in constant time and at changes in speed the marking machine does not react, so that the ratio of the two amounts of substance - liquid marker to beads or co-formulants - shifts.
  • a predetermined layer thickness must be adhered to, which requires a constant travel speed for the quantity-preconceived additions of material.
  • an adaptation of the driving speed for example, at 10 ° C outside temperature 4 km / h and at 15 ° C outside temperature 6 km / h. This not only changes the layer thickness, but also the uniform introduction of the profile particles. Because the usual from an upper metering and a lower centrifugal roller injection device operates constant time.
  • the invention is therefore an object of the invention to provide a method and an apparatus of the type mentioned above, which can avoid the disadvantages described and in particular allow largely without loss of substance a paint application with the same layer thickness and evenly embedded profile particles, optionally also with an additional with a Nachstreuer equipped marking machine.
  • This object is achieved with a method according to the invention in that the continuously measured driving speed of the marking machine in a central computing and control unit to which the injection device is connected, the marking machine is entered and in case of deviations from a target speed, the dosage of profile particles depending on the respective actual speed is adjusted proportionally.
  • the speed of a feed roller (metering roller) of the injection device is regulated in a speed-proportional manner.
  • a marking machine which is also equipped with a spreader, this also connected to the central computing and control unit and the application of a Nachstreuffens also regulated speed proportional, preferably in turn by speed control of a conveying roller of Nachrereuers.
  • An advantageous proposal of the invention provides that the spray gun, the injection device and - if available - the spreader can be switched on and off independently of each other, at the beginning of marking the injection device with flow to the spray gun and these time-delayed the spreader is turned on and the end of the marker first the spray gun, then the injection device and finally the spreader is turned off.
  • the scattering losses can be prevented in such a way that profile particles or after-scattering agents do not impinge on the paint surface but on the road surface.
  • the object underlying the invention is achieved with a device which is characterized in that the marking machine has a central computing and control unit, to which a measuring speed determining the measuring means and a trained with a controllable metering injection device and optionally a trained with a controllable metering spreader are connected.
  • the actual speed of the marking machine can be measured, for example, by means of a ground wheel and the measured value can then be fed into the central computing and control unit (PLC) for converting the speed to be preset for the controllable metering drive and optionally the spreader.
  • PLC central computing and control unit
  • electrical metering drives having an integrated electronic controller for speed adjustment be used.
  • the electric motors allow in a simpler and safer way, an independent switching on and off.
  • a preferred proposal of the invention provides that the injection device is formed with a diffuser-type deflecting means and is arranged with a variable, in set positions fixable suspension in the marking machine.
  • the suspension of the injection device with in all directions free rotational mobility and tilt adjustability, e.g. in the manner of a universal joint connection with linear displacement, allows a very uniform distribution and introduction of the profile particles in the spray jet or the spray pattern of the liquid marker of the paint spray gun.
  • the rotary / sliding joint can be set in the optimally adjusted position of the injection device, for example by screws.
  • the ideal setting can be determined visually and / or by measuring a sample-wise layer thickness with the distribution of the introduced profile particles.
  • An only indicated marking machine 1 which moves in the direction of the arrow P, is equipped with a spray gun or paint spray gun 2, an injection device 3 and a follower 4 which follows behind in the direction of travel.
  • the spray gun 2 carries the marking substance or the color with a fan-shaped spray jet 5 on the road surface 6.
  • the arranged in the vicinity of the spray gun 2 injection device 3 is adjusted so that metered supplied profile particles 7 enter the spray jet 5 before it hits the road surface 6, so that the profile particles 7 are mixed with the marker.
  • the provided in the direction of travel or arrow P behind spreader 4 scatters on the generated, still fresh color track, for example, also reflex beads or grip means 8.
  • the injection device 3 and the spreader 4 are designed for precise metering of the profile particles 7 or reflex beads / grip means 8 with a conventional roller assembly operating on the principle of a rotary valve, namely comprising a metering or conveying roller 9 and one cooperating therewith
  • Both the injection device 3 and the spreader 4 are here driven by a preferably electromotive, controllable metering drive 11.
  • the marking machine 1 has a central computer and control unit 12 designed as a programmable logic controller (PLC), into which the vehicle speed V F continuously measured via a ground wheel 14 enters via a signal line 13 shown in dashed lines as an actual value.
  • PLC programmable logic controller
  • the rotational speed of the metering / conveying roller 9 is correspondingly changed and adjusted via an outgoing from the arithmetic and control unit 12 to the metering drives 11 of the injection device 3 and the spreader 4, also dashed signal line 15 that a exact speed proportional dosage of the profile particles to be sprayed 7 or Reflexperlen / Grifftechniksmiftel 8 or the like Beistoffe guaranteed becomes.
  • the controllable or variable-speed metering drives 11 of the injection device 3 and the Nachstreuers 4 and also controllable, not shown drive the spray gun 2 allow these components independently on and off.
  • the special injection device 3 brings the profile particles 7 over a formed on the housing below the centrifugal roller 10, diffuser-like deflection means 16 and is in particular arranged with a movable in all directions, set in variably adjusted positions, schematically indicated suspension 17 in the marking machine 1.
  • This formed in the manner of a rotary sliding joint connection, not to be recognized, in the drawing plane rear reclining and locking device of the suspension 17 not only allows an adjustment of the inclination angle ⁇ to the road surface 6, but also any adjustments in the vertical and horizontal directions.
