Definitions

  • the invention relates to a workpiece, in particular produced by means of an additive method, which is provided with a coding or identification. Furthermore, a method for creating a workpiece with such a coding or identification is provided.
  • a workpiece can be, for example, a workpiece or object that is used in the furniture or component industry, in particular a piece of furniture or a part of a piece of furniture.
  • the aim of the invention is to provide a workpiece which is provided with a coding or identification under the stated framework conditions and which records and / or can record information, in particular workpiece-specific information.
  • a workpiece is provided with a surface structure that has been created and forms a decoration, with an optically detectable code being integrated in a reference area in the surface structure of the workpiece.
  • the invention has the advantage that coding or identification of workpieces is integrated into the visible surface of the workpiece without the identification as such being recognizable as such to an observer.
  • the marking consequently does not disturb the aesthetic impression. Rather, the identification is integrated into the visually perceptible surface of the workpiece and is therefore part of the decoration of the workpiece.
  • the identification can be recorded by means of an optical sensor and its information content can be decoded with a control device.
  • the identification Since the identification (coding) is integrated into the workpiece surface, it can be generated when the surface is created. Consistent identification of the workpiece is thus guaranteed even during production, thus increasing product safety. In addition, the identification remains connected to the workpiece over the life of the workpiece, whereas with known barcode stickers or printed labels there is a risk that they will become detached or rubbed off.
  • workpiece-specific information such as material data, creation date, workpiece number or the like, can be linked to the workpiece.
  • “Created surface structure” means a surface structure that is formed by machining, treatment or construction.
  • a surface of a basic workpiece can be provided with a layer that forms the surface structure, or the workpiece is manufactured together with the surface structure using an additive process the surface structure can be produced by means of a subtractive process.
  • the processes mentioned can also be combined with one another individually.
  • a decor is the exterior of the surface structure that is visually perceptible by the observer.
  • it can be a wood decor that imitates a wooden surface.
  • the coding has information parameters, the position in the reference area and / or a relation of the area of the information parameters to the area of the reference area representing or containing information. In this way, the coding can be inconspicuously provided on the workpiece.
  • the reference surface can be formed by several points provided in the surface structure. If the surface structure is a wood look, the points can be designed as knotholes or the like, for example.
  • the reference area can accordingly be defined on the basis of optically perceptible features.
  • the coding can include information parameters that are designed as a wave structure. This refinement has proven to be particularly advantageous in order to integrate coding into the visible surface of the workpiece.
  • the workpiece can also be designed in such a way that the coding is designed in one piece with the workpiece.
  • the coding is thus firmly linked to the workpiece and is therefore part of the decoration of the workpiece.
  • the workpiece can be formed in layers, in particular by means of an additive method. This enables the production of a large number of variants. It is preferred here that the coding is also created when the workpiece is created.
  • the workpiece is a piece of furniture or part of a piece of furniture.
  • the coding is designed to be optically detectable, in particular by means of a 3D scanning method. The coding can thus be read out, for example, by an appropriate device, and the information read out can be further used directly.
  • the surface structure comprises a wood structure, a motif or an image. If a wood structure is used, for example, knotholes or the like can define a reference surface. In the case of a motif or an image, the reference surface can be determined by features of the motif or the image.
  • the invention further relates to a method for producing a workpiece, a code being formed in the surface structure on the workpiece when the surface structure is created.
  • the method has the advantage, among other things, that an identification of workpieces can be integrated into the visible surface of the workpiece without the identification as such being recognizable as such to an observer.
  • the marking consequently does not disturb the aesthetic impression, but rather the marking is integrated into the visually perceptible surface of the workpiece and is therefore part of the decoration of the workpiece.
  • it is possible to detect the identification by means of an optical sensor and to decode its information content with a control device.
  • the coding is formed by an irregularly formed surface structure.
  • the coding can be designed as a wave structure.
  • the method can furthermore be implemented in such a way that the workpiece is formed in layers, in particular by means of an additive method, in particular by means of a melt layer method.
  • the coding and / or the reference surface is formed by means of a printing method, in particular by means of inkjet printing, or an additive method.
  • the coding can thus be designed individually for a specific workpiece.
  • the coding is designed to be optically detectable, in particular by means of a 3D scanning method.
  • the features of the method can each be used individually to further specify the workpiece described above.
  • Features of the workpiece described above can also be formed in the course of manufacturing the workpiece.
  • Figure 1 shows a plan view of a workpiece according to a first embodiment of the invention
  • Figure 2 shows a plan view of a workpiece according to a second embodiment of the invention
  • FIG. 1 shows a top view of a plate-shaped workpiece which is provided with a surface structure.
  • the surface structure is intended to simulate a wood surface.
  • images, motifs or the like can also be provided as the surface structure.
  • the surface structure can be applied to the surface of a workpiece using a 3D printing process, or an inkjet or laser printer. It is also possible to provide the surface structure during the additive formation of the workpiece in the surface of the workpiece.
  • a wooden surface is imitated, which can be found in such a surface through cut annual rings, knotholes or other regular or irregular features.
  • a reference area between characteristic points A, B, C, D is defined in the surface of the workpiece.
  • the characteristic points are formed by knotholes, the type of characteristic points being defined as a function of the specifically selected surface structure.
  • the points A-D are each central points in the area of the respective knothole.
  • the characteristic points AD are connected by means of lines in FIG. 1, so that a polygonal, two-dimensional area is shown is.
  • the area defined by the corner points AD is also referred to as the search field.
  • the workpiece shown in FIG. 1 also includes information parameters I, II, which are designed as knotholes on the surface of the workpiece.
  • the information parameters I, II are characterized by an irregularly designed area.
  • the configuration of the information parameters I, II is defined as a function of the specifically selected surface structure.
  • the surface of the workpiece can be recorded by means of an optical sensor and the search field defined between the corner points A, B, C, D can be recognized. Furthermore, the borders, and thus also the area, of the information parameters I, II are detected.
  • the arrangement of the information parameters I, II in the search field and the overlapping of the information parameters I, II with the border of the search field define individual information that is used to identify the workpiece.
  • the sensor system is connected to a database stored in a cloud, so that specific information can be queried based on the detection of the identification of a workpiece.
  • FIG. 2 shows a second example of a workpiece with a surface which is designed similar to that in FIG. 1.
  • two information parameters I ′, II ′ are formed, the scope and dimensions of which differ from that and that according to FIG. 1.
  • the arrangement as well as the overlap of the information parameters I ', II' in or with the search field defined by the corner points A, B, C, D is a different piece of information from the embodiment shown in FIG accordingly specifies and identifies the workpiece shown in FIG.
  • characteristic points A, B, C, D and the information parameters in the exemplary embodiments are designed as knotholes, these are not perceived by the viewer of the workpiece as marking in the sense of a barcode or QR code. Rather, the viewer sees the characteristic points and the information parameters as part of the actual decoration. Deviations between individual workpieces are recognized by the observer as a variation in the decoration if workpieces are arranged next to one another, for example in the case of ceiling or floor panels. This circumstance thus contributes to increasing the perceived value of the workpiece.
