Definitions
- the invention relates to a method for the quality inspection of bristles intended for bristle products, in particular brushes, which are shaped at their ends on the use side, in particular rounded to a spherical tip, in that the ends of a plurality of bristles lying next to one another are recorded with an image recognition device and are evaluated by image evaluation Degree of shaping of the bristle ends is closed.
- the invention further relates to the use of bristles tested in this way for bristle products and bristle products with properties that visualize the quality of the shape of the bristles.
- Plastic bristles are now produced from endless monofilaments or monofilament strands by cutting to the desired length.
- the cutting process does not always result in a flat cutting surface that is perpendicular or inclined to the bristle axis, but burrs also form on the cutting edges.
- the invention is based on the object of proposing a method by means of which a meaningful and reproducible quality check of the user-side ends of the bristles is possible after their processing.
- this object is achieved in that the bristles are aligned with their jacket in parallel position next to one another and with their ends in a flat envelope surface, before or after they are surface-structured or colored at their ends to contrast them with the bristle jacket , and then the ends in the envelope are recorded with the image recognition device.
- This can be done, for example, with an optoelectronic camera that uses its optic see axis is aligned perpendicular to the envelope surface and parallel to the bristles.
- the bristle ends form, as it were, individual small areas in a uniform area grid.
- the structure or color of these individual, small areas contrast with the very smooth bristle coat.
- this grid of small areas is imaged via the optoelectronics. Flawlessly shaped ends with an ideally hemispherical, semi-elliptical or conically rounded contour all show the same reflection behavior and consequently result in a uniform grid pattern as an image.
- the image quality of the bristles examined can be compared qualitatively and quantitatively by comparing an image with a master image which reproduces the desired state. Instead of an image comparison, any other electronic implementation and evaluation can also be used. With colored bristle ends, the quality is visualized at the same time.
- Bristles the ends of which deviate from the ideal contour or which do not lie completely within the relevant plane, appear in the raster image as interfering surfaces. Tolerances can be defined for the frequency of the interfering surfaces; if they are exceeded, the bristles or the brush as a whole are discarded.
- the area percentage of the area can also be checked as part of the quality inspection
- Quality bristles and the number determine the bristles per unit area and also check compliance with tolerances.
- This quality check is preferably carried out prior to the manufacture of the bristle product, in that the bristles are positioned in parallel after being cut from the continuous monofilament or from a multi-core monofilament strand, and their ends are also pushed into a common, flat envelope surface. The bristle ends are then mechanically, e.g. by grinding or the like , shaped, especially rounded. The quality check can then be carried out in the same position, but possibly also after moving to a different level.
- the method according to the invention can also be implemented on the finished brush, provided that the bristle ends are all in one plane.
- the bristles can be combined into bundles or attached to the brush body standing upright.
- the ends of the bristles can be colored in a contrasting manner before the test.
- a contrasting color can be applied to the ends of the bristles by application or dipping.
- the shaped ends of the bristles are ground or polished after coloring and before the quality check. If the contrasting is carried out by structuring, it is advantageously provided that the ends of the bristles are preformed by mechanical grinding and structured on the surface and then checked. In this case, the structured ends are only ground or polished after the image has been evaluated.
- the bristles are made from a plastic filled with — optionally reversible — color-reactive pigments and only the ends of the bristles are treated before and / or during the test in order to achieve the color change. Pigments that react to heat or radiation energy by changing color are particularly suitable for this. If the color reactivity of the pigments is reversible, the individual bristles have the same appearance before and after the quality check. If, on the other hand, it is a permanent coloring, this remains on the bristle and thus also on the finished brush and can initially serve the customer as a guarantee that the bristles or the brush have been tested qualitatively.
- bristles with a dye arranged inside are used and the dye is distributed over the rounded surface when the ends are formed. Bristle ends colored in this way can also be checked optoelectronically in the aforementioned manner.
- the process can be carried out, for example, in such a way that the unprocessed bristles lying in parallel with one another and with their ends in a flat envelope surface are preformed and structured by means of a grinding surface which acts parallel to the envelope surface and acts on the ends , around then subject them to the test.
- the ends of the bristles can be loaded with a disk parallel to the envelope surface by means of which color is transferred.
- This process ensures that the coloring takes place under the same geometric and kinematic conditions as the shaping of the bristle ends. This process can also be easily integrated into corresponding manufacturing processes.
- the structured bristles can be fine-ground or polished again with a colored disc parallel to the surface before the test.
- the method according to the invention can also be modified in such a way that when bristles with color-reactive pigments are used, heat or radiation energy is brought to bear on the ends lying in the flat envelope surface.
- a further preferred method variant is characterized in that the bristles are axially displaced relative to one another after the test in order to place their ends in a predetermined contoured envelope surface, and are then processed while maintaining their relative position to the bristle goods.
- the bristle ends are permanently colored on the surface by the process according to the invention or by embedded, color-reactive pigments, the colored ends are retained after the quality check. They do not interfere with the intended use of the brush.
- the invention even opens up the possibility of visualizing the degree of wear or wear of the bristles.
- the bristles wear conically to the point on their near-end jacket by removing material.
- you remove the coat you remove the paint.
- the respective color in which the entire bristle surface appears can then serve as a wear indicator.
- the invention further relates to bristle articles, in particular toothbrushes, with bristles, the ends of which are shaped, in particular rounded, and which are characterized in that the shaped ends of the bristles are colored in a contrasting manner with respect to the bristle sheath in order to visualize the shaping quality.
- the bristle field with the contrasting colored bristles appears optically as a uniform grid area, so that the quality of the shaping is visualized for the user.
- a color is applied to the ends of the bristles on the surface.
- the bristles contain color-reactive pigments which react to heat or radiation energy with a color change, and that the ends of the bristles are treated with heat or radiation energy until the color changes.
