Definitions

  • the present invention relates to a method for applying a position marking for a work position to a substrate, for example a wall, a ceiling, a floor or the like, at a marking position assigned to the position marking. Furthermore, the invention relates to a marking system.
  • work positions for example drill hole positions or cutting lines
  • position markings in order then, for example, to be able to drill or saw precisely. This necessary preparatory work is not only very time-consuming, it is also often associated with significant measurement errors.
  • the object is achieved by a method for applying a position marking for a work position to a substrate, for example a wall, a ceiling, a floor or the like, at a marking position assigned to it, comprising the steps: a. Unsystematic or systematic movement of a portable marking system within a marking area; b. determining, preferably regularly determining, at least one position of the marking system; c. Marking at the determined position of the marking system if the determined position matches the marking position or at least matches the marking position up to a predefined or predefinable degree of accuracy.
  • the invention is therefore based on the idea that a user who wants to place the position marking on the ground usually knows or can estimate at least approximately the area where the position marking is to be located.
  • an opening for a supply line for a sanitary element for example a water supply line for a washbasin
  • the user can estimate that this opening must be in an area close to, but below, the washbasin.
  • the user can bring the marking system close to the sink and move it systematically or unsystematically within a certain area, and thus within a marking area.
  • the marking system can then apply the position marking precisely on the basis of the procedural determination of its position. Manual measuring and manual marking can thus be omitted; Incorrect placement of the position marking is avoided and the time required can be significantly reduced.
  • the marking area can also be selected to be relatively small.
  • the marking area can be selected as the area of the background containing and surrounding the marking position.
  • the marking area can be selected to be relatively small.
  • it can comprise at most 10 percent, particularly preferably at most 3 percent, of the surface of the substrate.
  • the marking area can, for example, be less than 1 m 2 , preferably less than 0.5 m 2 .
  • the underground for example a wall to be provided with the position marking, can have an area to be marked of at least 10 m 2 , in particular also of at least 50 m 2 .
  • the time required can also be reduced by such a relatively small selection of the marking area.
  • the position marking can have a monochromatic and/or linear form such as a line, a cross and/or a circle. Alternatively or additionally, it can also include at least one symbol, one number and/or one character.
  • the position marking can be made by spraying, for example using an inkjet nozzle or the like, by pressing on and/or gluing, by mechanical processing, for example by engraving, and/or by means of electromagnetic waves, e.g. B. by means of a laser, in particular by local heating, applied to the environment.
  • the position of the marking system determined or to be determined can correspond to a position of a marking unit of the marking system or of a marker of the marking unit, for example an inkjet nozzle.
  • the position can correspond to a position within the marking system at which the marking system processes the background, for example applying a colored dot to the background.
  • the position of a target point within the marking system can be determined and the position of the marking system can be derived from the position of the target point by adding a suitable offset value.
  • the offset value can have a vector value.
  • the production costs for the marking system can be kept low despite the considerable advantages that the method according to the invention brings with it using the marking system. Since according to the method the position of the marking system is monitored, it is ultimately sufficient that at some point in time the marking system suitably reaches the marking position. Complex and cost-intensive mechanics such as in printing presses, in particular in plotters for large areas, through which the marking system can travel with high precision on a predetermined route within a very large traversing range to the marking position, are therefore not required.
  • ceilings or the like can also be provided with position markings.
  • the position marker and/or the marker position may be stored in a BIM (Building Information Modeling) model, a CAD model and/or the like. Generally, they may come from a building plan and/or a blueprint.
  • BIM Building Information Modeling
  • a “portable” system can be understood to mean a system that can be kept in suspension by a user for an extended period of time.
  • the portable system a weight of at most 10 kg, preferably at most 3 kg, particularly preferably at most 2 kg.
  • the marking system can be in several parts.
  • the position determination system can have a separate transmitting part and a receiving part located on the rest of the marking system part. Then the portability of the marking system can only refer to one of the parts of the marking system, in particular to a part to be moved and/or held in suspension by the user.
  • the degree of accuracy and thus a maximum permissible distance between the marking position determined relative to the surroundings and the marking position to be determined can be limited to a maximum of 1 cm, preferably a maximum of 2 mm, particularly preferably a maximum of 1 mm.
  • the marking area can be selected as a non-contiguous area.
  • partial areas in which at least one of the marking positions of the respective position markings is to be expected can be selected.
  • the marking area can then be composed of the partial areas.
  • Marking at the determined position can be understood to mean that the complete position marking is applied to the substrate. Alternatively or additionally, this can be understood to mean that only part of the position marking is applied when the marking position is reached in a suitable manner. If, for example, a cross is to be applied, it is conceivable to apply only part of the cross, for example one of the four arms of the cross, to the substrate when a corresponding position is reached. The remaining parts of the cross can then be applied at a later point in time when suitably offset positions are reached.
  • an additional step can be provided within which information is stored in a memory about the fact that part of the position marking or the position marking as a whole has been applied to the surroundings. Before possibly reapplying the part of the position marker or the Position marking as a whole can then be checked in a further method step as to whether the respective part of the position marking or the position marking as a whole has already been applied. It may then be possible to avoid applying this part or the position marking twice.
  • a stationary coordinate system can be defined relative to the subsoil.
  • the coordinate system can be defined independently of the marking system.
  • a reference point of the coordinate system can be selected, for example, in the area of a corner of the environment.
  • the determination may precede step a.
  • the coordinate system can be one-, two- or three-dimensional. The marking position and thus the location of the position marking can thus be defined relative to the coordinate system.
  • a position of the marking system is preferably also determined.
  • the position can be determined relative to the direction of gravity.
  • the offset value can thus be suitably adjusted on the basis of knowledge of the position.
  • a marking unit with at least two markers, preferably at least 24 markers, particularly preferably at least 128 markers, can be used for marking at the determined position.
  • the marking unit can in particular correspond to an arrangement of several markers.
  • the arrangement can be linear or planar, in particular polygonal.
  • the position of the marking system determined or to be determined can correspond to the position of one of the markers.
  • a number of positions of the marking system are preferably determined in accordance with step b of the method.
  • Such a position of the marking system is particularly preferably determined for each of the markers. This can be done by determining the position of the target point and then adding marker-specific offset values. These offset values can also be vector values.
  • At least one of the markers can be an inkjet nozzle, a mechanical dye transfer device, for example a stamp, a processing tip, for example a controllable needle tip, for spot processing of the substrate or the like.
  • the movement can be passive.
  • the user of the marking system can manually move the marking system over the marking area.
  • the movement can be a swiping movement.
  • it can be a movement that can be carried out by the user and is preferably ergonomic for the user.
  • a building element can also be understood to mean a partial element, for example a part of a wall.
  • the method is particularly well suited for use in the field of building construction and/or civil engineering.
  • Time savings can also be achieved if multiple position markers are marked within the marking area.
  • the correspondence of the position of the marking system according to step c can be checked with regard to each marking position of the respective position markings.
  • the marking system can first be moved to a starting point within the marking area as part of an initial positioning in order to keep the marking area as small as possible and thus save further time to achieve.
  • the scope of the invention also includes a marking system for marking a position marking for a work position on a substrate, for example a wall, a ceiling, a floor or the like, at a marking position assigned to the position marking, comprising a marking unit with at least one marker, a position determination system for detecting a position of the marking system and a control unit that is set up at least once by means of the marking unit To mark a position marking or at least a part of the position marking on the ground if the marking system is at the marking position or in a measurement area around the marking position that corresponds to a predefined or predefinable degree of accuracy, and not to mark a mark if the marking system is outside the measurement area .
