Definitions

  • the invention relates to a device for producing profiled horizontal road markings according to the preamble of the first claim.
  • the invention relates to a method for operating the device according to the preamble of the sixth claim.
  • EP-A-0 280 102 describes a structuring or profiling in which coarse particles are embedded in multiple layers. This process is used both to create and to renew horizontal markings, such as boundary, guideline and warning lines. The device used for this is very complex and associated with high costs.
  • DE-A-1 534 209 describes an embodiment in which the profiling or structuring by means of a localized pressure, for example by means of a gear-like wheel, is generated, which is exerted on the not yet solidified paint layer.
  • This type of profiling is also complex and rather complicated.
  • the various parts have to be cleaned frequently, which is associated with high costs.
  • EP-A-0 148 494 and EP-A-0 422 346 disclose devices for producing drop-shaped, profiled road markings.
  • EP-A-0 148 494 describes an embodiment in which the color compounds are pressed through a tube through a plurality of nozzles with intermittent air pressure pulses in such a way that a teardrop-shaped structuring or profiling is produced. Not only is the outlay in terms of equipment very high, but there are very often faults, particularly in the case of viscous compositions, and the risk of constipation is very high. Furthermore, cleaning the system is complex and costly.
  • the object of the invention is to create a device and a method for its operation which do not have the disadvantages of the existing designs.
  • a solution is sought that preferably has no moving parts, because these wear out easily and often have to be cleaned or replaced.
  • the main advantages of the present embodiment are the simple structure and the fact that there are no moving parts that have to be cleaned or replaced again and again. Interruptions in the use of the facility for maintenance are practically impossible. As a result of the simple structure, the acquisition costs are also very low.
  • the only moving part is the slider, which does not have to be moved in a particular operating mode.
  • FIG. 1 and 2 show a storage container 1 with two vertical walls 15 and 16 and a lower inclined wall 17 and a lower bottom surface 18, the wall 15 merging into the inclined wall 17 approximately halfway up.
  • a slide 2 with which it is possible to adjust the outflow of the amount of paint 13 in the storage container 1 per unit of time. If the slide 2 is moved downwards or upwards, this quantity or the flow rate can be adapted to the requirements, taking into account the viscosity of the amount of paint.
  • the bottom surface 18 merging into a guide plate 4 with an edge 5.
  • This edge 5 is sawtooth-shaped and / or corrugated, so that the laminar flow of paint or mass is broken and turns into turbulence, so that multiple paint partial flows 6 arise when the vehicle moves in the direction of arrow 7.
  • the turbulence causes the partial flows 6 to convert into drops 12 as a result of the air jets 11 through holes 9 in a wall 19 of a compressed air tank 8.
  • the container 8 is fed by an inlet 21 and is under an adjustable excess pressure. This pressure can depend on the type of paint and the speed of the vehicle on which the sprayer is mounted.
  • the air flow is directed against the lower side of the baffle plate 4 directed obliquely downwards and generates the turbulence required for drop formation on the lower edge 5.
  • the drops 12 dropping off from the edge 5 between the tips 10 remain as blobs on the street surface 14 and have a structured, profiled or raised shape, as a result of which they improve the reflection of the light rays incident on them from headlights and thus improve the night visibility of the marking cause.
  • the distance of the compressed air tank 8 from the edge 5 and the pressure in the tank 8 are chosen so that the turbulence is as favorable as possible for the drop formation. It is pointed out that this distance also depends on the flowability of the ink mass, so that it is expedient for different types of ink quantities to use storage containers 1 with different geometries. There is also the possibility, in a specific embodiment, of changing the distance by moving the compressed air tank 8 before each use with different color consistency.
  • the air flow along the guide plate 4 generates an accelerated falling speed of the drops 12 against the roadway, thereby preventing the drops 12 from flying away or from not being sufficiently firmly connected to the road surface.
  • the size of the drops 12 is mainly determined by the size and shape of the incisions 20, as well as by the pressure in the compressed air tank 8 and by the inclination of the guide plate 4. By changing one of these sizes, the size and shape of the drops can be changed if one starts from a color mass with a certain viscosity.
  • the device is normally supplied ready for normal use.
  • the compressed air tank 8 can be moved on the bottom surface 18 and can be adjusted as required.
