Description

  The present invention relates to a cosmetic material repair method, a cosmetic material repaired by the cosmetic material repair method, and a cosmetic material repair device. More specifically, the present invention relates to a makeup in which a pattern is applied to the surface of a base material based on prestored pattern data. The present invention relates to a cosmetic material repair method for repairing a defective portion of a material, a cosmetic material manufactured by repairing the cosmetic material repair method, and a cosmetic material repair device.

Conventionally, wood materials are often used as building materials used indoors and outdoors.
Natural wood materials are often used for such wood materials because of the beauty of the wood grain pattern on the surface, but natural wood materials have defects such as skins, knots, spears, and stains on the surface. May occur during growth or processing.

In Patent Document 1 below, a wood material defect repair device has been proposed in order to solve such a problem.
This defect repair device includes a line CCD camera that images the surface of the material to be repaired, and an ink jet that applies a repair agent (color paint or bleach corresponding to the base color of the wood material) to the defective portion of the material to be repaired. And a control unit that controls ink ejection based on image data from the CCD camera.
The defect repairing apparatus having the above-described configuration is configured to image the surface of the material to be repaired with the CCD camera, generate imaging data indicating the density, determine the presence / absence of a defect with the control unit, and determine the position, shape, and brightness distribution. And the like.

In addition, the defect repair device identifies the determination unit area constituting the defect to be repaired determined and determined as described above according to its brightness in three stages, and the repair agent corresponding to this is identified. The dot size is “large”, “medium”, and “small”, and the repair agent is applied by an ink jet printer.
Thereby, it is prevented that a repair agent is applied more than necessary to give a sense of incongruity with the normal part of the surface of the wood material, and repair can be performed while maintaining a natural state.
JP 2003-225902 A

  However, in the defect repair apparatus described in Patent Document 1, since the application amount of the repair agent is controlled by the dot size set according to the brightness of the defect to be repaired, the brightness is relatively high. In the determination unit area constituting the defect to be repaired, since the dot becomes small, a gap is formed between the dots, which may impair the natural appearance.

In recent years, a lot of highly decorative cosmetics have been provided, in which a pattern layer is formed by printing a wood grain pattern or other pattern on the surface of an inexpensive base material due to soaring natural wood materials or environmental problems. Has been.
In such a decorative material, if a defective part such as a scratch or a stain or a printing mistake occurs on the wood grain pattern printed on the surface, the substrate surface or the base applied to the substrate surface is exposed, and the appearance It is not preferable, and the value as a product is reduced.
When the defect repair device described in Patent Document 1 is applied to repair a defective portion of the pattern generated on the surface of the decorative material as described above, in a portion having a high brightness as described above, a dot and a dot A gap is formed between them, which may impair the appearance. In other words, although Patent Document 1 discloses the point of repairing by ink jet painting, it is not intended for a decorative material having a pattern on the surface by ink jet painting, but for concealing stains or the like peculiar to wood materials. In addition, a repair agent is applied by inkjet coating, and a sense of incongruity occurs between the repaired portion and the surrounding pattern pattern, and it is difficult to reproduce the pattern without a sense of incongruity.

  The present invention has been proposed in order to solve the above problems, and its purpose is to identify a defective portion of a decorative material having a pattern on the surface of a base material based on prestored pattern data. Another object of the present invention is to provide a cosmetic material repair method that can be repaired by ink jet painting without causing a sense of incongruity with other parts, a cosmetic material that is manufactured by repairing using the cosmetic material repair method, and a cosmetic material repair device.

Cosmetic material before repair, (b) is a schematic plan view showing the cosmetic material after repair in the embodiment, FIG. 5 is a cosmetic material repaired by the cosmetic material repair method according to the embodiment It is a schematic sectional drawing shown.
In FIG. 4, the defective portion 13a and the repaired portion 13b are represented by a two-dot chain line. In FIG. 4A, the wood grain pattern layer 13 is peeled off, and the ink receiving layer 12 is exposed, resulting in the defective portion 13a. An example is shown.

The decorative material 10 to be repaired by the decorative material repairing method of the present embodiment is sprayed from an inkjet coating apparatus (not shown) onto the surface of a wooden base material 11 such as a laminated material, plywood, particle board, or wooden fiberboard. A white ink receiving layer 12 for fixing the ink is formed, and an ink color is selected based on the pattern data stored in advance on the white ink receiving layer 12, and the wood grain pattern layer 13 is formed by an ink jet coating apparatus (not shown). It is the formed plate-shaped thing (refer FIG.4 and FIG.5).
In addition, as the decorative material 10 applicable to this embodiment, it is not restricted to the plate-shaped thing of an illustration, A magnitude | size, a kind, and a shape are not specifically limited. For example, it is also widely used as an interior building material and exterior building material for buildings, and other wood-based materials and resin materials are used as a base material and patterns are applied based on pattern data stored in advance on the surface. Applicable.
In addition, the surface layer of each substrate is subjected to a surface treatment other than the ink receiving layer described above, or the substrate surface is concealed to form a pattern layer by an inkjet coating apparatus. There may be.
Furthermore, the pattern data is not limited to a pattern obtained by photographing a natural name tree or an artificially created pseudo-grain or the like, but may be another pattern or the like.

After the formation of the grain pattern layer 13 as described above, when a defective portion 13a is generated on the surface of the decorative material 10 as shown in FIG. 4A, the repair is performed as follows.
That is, as shown in FIG. 1, the surface of the decorative material 10 with the pattern is imaged (step 100). Next, the defective image 13a is identified by comparing the captured image data of the surface of the decorative material 10 obtained by imaging with the reference image data including the pattern data stored in advance (step 101). The defective portion is identified by extracting pattern patterns such as missing patterns, scratches, and dirt by an image processing method such as pattern matching.

  Next, a pattern to be applied to the specified defective portion 13a is determined based on the reference image data, and repair data is generated (step 102). Here, the repair data includes at least a pattern pattern and hue information. Based on the repair data generated at the end, inkjet coating is performed on the specified defective portion 13a (step 103), but a protective layer is formed on the surface of the decorative material 10 after coating the defective portion 13a as necessary. (Step 104).

Each step is preferably performed in the manufacturing process of the decorative material 10. For example, before the step 100, the decorative material 10 on which the wood grain pattern layer 13 is formed is changed depending on whether or not the defective portion 13 a is generated. The product may be classified into a non-defective product and a defective product, and repair may be performed by the cosmetic material repair method only in the case of a defective product having a defective portion 13a.
Further, when the wood pattern layer 13 is formed by coating the surface of the decorative material 10, it may be formed by other printing methods such as gravure printing other than inkjet coating.
In this case, pattern data used for gravure printing or the like is used as reference data, and this is compared with captured image data obtained by imaging the surface of the decorative material 10 to extract a defective portion, and further repaired by inkjet painting. Repair data is generated by selecting ink colors necessary for the operation.

  The control unit 30 includes a CPU 31 constituting a control calculation means, a storage means 32 for storing various programs and pattern data 32a serving as reference image data, an image memory 33 for storing various image data, and the like. The repair data generation means is configured.

Next, a specific example of the cosmetic material repairing method executed by the cosmetic material repairing apparatus A configured as described above will be described.
First, the CCD color line sensor unit 21 is driven to image the surface of the decorative material 10 placed on the base 20.
At this time, as described above, the imaging unit 24 moves and scans the decorative material 10 in the Y direction, sequentially captures the image for each line, and images the entire surface of the decorative material 10. The captured image is converted into a digital image by the A / D converter 22a and stored in the image memory 33 as captured image data 33b.

The CPU 31 reads the reference image data 32a including the pattern data stored in the storage means 32, stores it in the image memory 33 as reference image data 33a, and stores it in the reference image data 33a and the image memory 33 by an image processing program. The defective image 13a is specified by comparing the captured image data 33b.
Here, for comparison between the reference image data 33a and the captured image data 33b, a known image processing technique can be applied. For example, after aligning the reference image data 33a and the captured image data 33b by pattern matching, the difference between them is calculated, and the difference result is equal to or greater than a certain value (threshold) or less than a certain value (threshold). These points may be extracted and specified as defective points.

At this time, it may be converted into RGB digital data and subjected to color processing by color extraction, color shading processing, or filter processing such as expansion or contraction so as not to detect minute noise.
For example, RGB shading is represented by a luminance value of 256 gradations for each pixel by color shading processing, and the luminance value of the reference image data 33a is compared with the luminance value of the captured image data 33b. Also good. In that case, although detailed description is omitted, the average value, standard deviation, maximum value, and minimum value of the luminance value in the corresponding part of the data may be calculated, and the defective portion 13a may be extracted by comparing the shades. .
In addition, in the case where the specified defective portion 13a is caused by the exposure of the ink receiving layer 12 or otherwise (for example, when the pattern is different from the reference image data, or when it is dirty, the ink receiving layer 12 is peeled off. It is preferable to specify whether the surface layer of the base material 11 is exposed).

Next, a pattern to be applied to the defective portion 13a specified as described above is determined based on the reference image data 33a, and repair data 33c is generated.
The repair data 33c includes information such as the pattern pattern, position and shape of the specified defective portion 13a, lightness, saturation, and hue for each pixel, and a combination of ink colors used for repair.
At this time, as described above, when the defective portion 13 a is other than the exposure of the ink receiving layer 12, the repair data 33 c further includes information for forming the ink receiving layer 12.

Next, on the basis of the repair data 33c generated and stored in the image memory 33, the inkjet coating injection unit 25 is driven, and the nozzle head 29 is driven and controlled by the nozzle head driving means 26a to the specified defective portion 13a. The ink is ejected from the paint.
At this time, as described above, in the case where the defective portion 13a is other than the exposure of the ink receiving layer 12, after the ink receiving layer 12 is formed, the ink for forming the grain pattern layer 13 is further sprayed and applied. Do.

  As shown in FIG. 4B, the defective portion 13a painted by the ink jet coating injection unit 25 is repaired to become a repaired portion 13b, but repair data 33c is generated based on the reference image data 33a. There is no sense of incongruity between the grain pattern layer 13 applied around the defective portion 13a and the repaired portion 13b. Further, in the example shown in the figure, since the paint is applied with colors and shades that match the wood grain pattern and the conduit pattern, the cosmetic material 10 is excellent in design without impairing the natural appearance. That is, since the pattern to be applied to the defective portion 13a is reproduced based on the repair data 33c and becomes the repair portion 13b, the repair can be performed with high accuracy.

After coating the defective portion 13a, the protective layer 14 is formed as shown in FIG. 5, and the decorative material 10 is manufactured.
The protective layer 14 is formed by sticking a transparent protective sheet or film so as not to obstruct the applied pattern, or a protective coating film by painting with a transparent resin paint (for example, urethane, epoxy, etc.) It is formed by.
Thus, by forming the protective layer 14 after painting on the defective portion 13a, the surface of the decorative material 10 can be protected from being scratched and the like can be reduced.
In addition, the protective layer 14 may be formed by the cosmetic material repair apparatus A, and may be formed as a separate process.
In addition, a weather-resistant acrylic, methacrylic, urethane, or fluorine-based ink can be applied to the ink jetted when applying a pattern on the surface of the decorative material and the above-described repair without forming the protective layer 14 separately. Or a resin layer such as a coating layer may be used as a protective layer.

As described above, according to the cosmetic material repair apparatus A and the cosmetic material repair method according to the present embodiment, the captured image obtained by imaging the pattern data 32a (reference image data 33a) stored in advance and the surface of the cosmetic material 10. Since the defective portion 13a on the cosmetic material surface is identified by comparing the data 33b and the defective portion 13a is painted based on the repair data 33c determined based on the reference image data 33a, the repair portion 13b and its There is no sense of incongruity with the surrounding pattern, and the surface of the decorative material can be repaired with high accuracy.
Further, since the defective portion 13a is coated by the ink jet coating injection unit 25, a small defective portion can be repaired with high accuracy. Furthermore, since the inkjet coating jet unit 25 is easy to control, it can also control the application of ink to areas other than the defective portion, and ink is not wasted, so that the surface of the cosmetic material can be repaired at low cost.

Moreover, the repair can be performed without hindering the natural appearance of the natural wood tone of the decorative material 10 having the wood grain pattern layer 13 formed on the surface like the decorative material 10 of the present embodiment.
In particular, since the defective portion 13a is coated by the ink jet coating jet unit 25, a natural wood grain pattern can be reproduced by forming a pattern with a fine dot pattern, and the decorative material 10 having excellent design can be provided.
Furthermore, in the present embodiment, the cosmetic material repair device A forms a part of the cosmetic material production line, and is located downstream of the defective material selection of the cosmetic material 10 with the pattern as described above. Repair is possible on the repair line in the decorative material production line, improving productivity.

Furthermore, as described above, by forming the wood grain pattern layer 13 on the surface of the decorative material 10 using an ink jet coating apparatus (not shown), the repaired portion 13b is also formed when the repaired portion 13b is formed by painting on the defective portion 13a. The gloss and color of the 13b and the wood grain pattern layer 13 in the other portions are the same, so that a sense of incongruity does not occur and repair with higher accuracy is possible.
Furthermore, since the pattern data 32a used when the wood grain pattern layer 13 is formed by the ink jet coating apparatus can be used as the reference image data 33a at the time of repair, the repair can be performed easily and reliably.

In the present embodiment, the image pickup unit 24 of the CCD color line sensor unit 21 and the nozzle head 29 of the inkjet paint injection unit 25 are moved XY relative to the decorative material 10. It may be configured to move in the Y direction, or the decorative material 10 may be configured to be movable in the Y direction, and the nozzle head 29 may be configured to be movable in the X direction with respect to the decorative material 10.
