Description

[Detailed Description of the Invention] Technical Classification/Field> The disclosed technology belongs to the technical field of designing a flocked part in which a large number of piles are flocked on the base material surface of furniture, automobile interior materials, etc.

<Explanation of the gist> The invention of this application is for the flocked surface of pile flocking, in which adhesive is applied to a predetermined thickness on the base material surface of furniture, automobile interior materials, etc., to be designed in a predetermined shape such as a pattern or a letter. This invention relates to a method for designing a flocked part, and in particular, as described above, an adhesive is applied to a base material surface, and a gas such as air is applied to the adhesive which is in a deformable state before solidifying. After the setting design is formed by unevenly spraying the adhesive and forming an uneven surface on the adhesive, a pile is planted on the uneven surface of the adhesive-F, and further, the base is applied as described above. After the adhesive is applied to the material surface, piles are flocked on the adhesive surface, and then gas is unevenly sprayed onto the adhesive and the pile in the same manner as above) to create an uneven surface on the adhesive. This invention relates to a method for designing a part of a flocked part by forming a pile and at the same time changing the direction of the pile as desired.

<Prior art> In general, piles are uniformly formed on the surface of the house by electrostatic flocking etc. to improve the appearance and design of automobile interior materials, etc.
-One, a technique was developed to create a soft and luxurious atmosphere by densely flocking hair, and in history, the above-mentioned flocking was used to create text, pictures, etc.
There was a need to express pre-painted patterns such as patterns,
There was a demand for technology that could accommodate these two steps.

In order to meet the above-mentioned needs, a new technique is used in which the base of the workpiece is processed and transformed into a desired design, and then an adhesive is applied to the processed surface and pile is flocked, thereby creating the desired design. A method has been devised and put into practice that further enhances the design without reducing the soft and luxurious atmosphere of the pile by making it stand out.

<Problems with the prior art> However, in the above-mentioned prior art method of creating a design in which the workpiece base is processed and deformed to create flocking, the same workpiece is used to manufacture flocked products with different designs for multiple types of flocked parts. In this case, it is necessary to make separate workpieces that differ only in the base shape of the workpiece and are otherwise the same, and the number of mold types increases in the manufacturing process, resulting in a large amount of capital investment.Moreover, the number of man-hours for mold management and changeovers increases, and the work This is complicated and has the disadvantage of significantly increasing the cost of the product.

When adhesive is applied to a workpiece base surface that has been processed and deformed, it is difficult to faithfully reproduce the pile texture and form unevenness on the processed uneven surface due to the flow of the adhesive.
[There was also a point.

<Purpose of the Invention> The purpose of this invention is to solve the problems of the method for designing the flocked part of flocked parts based on the above-mentioned conventional technology as a technical problem to be solved, and to propose a design that takes advantage of the advantages of "1" interior fl′j′″E # L

J 171 B "D &°3"-61) The present invention aims to provide a method for designing a flocked part.

<Structure of the Invention> In accordance with the above-mentioned purpose, the structure of the invention of this application, which is summarized in the above-mentioned claims, is to solve the above-mentioned problem. While the adhesive applied to the base of the workpiece is in a plastically deformable state before solidifying, a gas such as air is unevenly sprayed onto the adhesive along the desired design to form the adhesive according to the set design. It is important to flock the pile onto the adhesive surface after forming the uneven surface. Alternatively, the adhesive is applied to the base of the workpiece and the adhesive solidifies after being flocked. By spraying air or other gas unevenly on the adhesive and the flocked pile in the previously plastically deformable state, as described above, the adhesive is made to form an uneven surface in accordance with the preset conditions. At the same time, the direction of planting the piles can be changed as desired, making it possible to draw a design that matches the soft and luxurious atmosphere of the flocked surface.

<Example> Next, an example of the invention of this application will be described below with reference to the drawings.

In the embodiment shown in FIGS. 1 to 4, as shown in FIG. , as shown in FIG. 3, a plate 5 having holes 4, 4, etc. formed according to a predetermined design is installed above the adhesive 3, and room temperature air 6 is blown from above the plate 5. (
By blowing, the air G is unevenly passed through only the 4 portions of the holes provided in accordance with the predetermined design, and this unevenly blown air causes the adhesive surface 7 to form unevenness in the predetermined design. Then, as shown in FIG. 4, groups of piles 8 are flocked on top of the adhesive 7 using an electrostatic flocking device (not shown) in the same manner as in the conventional method.

Therefore, the 8 groups of flocked piles themselves express pre-pine with a unique texture and excellent design.

Next, in the example shown in FIGS. 5 to 7, as shown in FIG. 5, the adhesive 7 was applied to the work base 1 as described above, and 8 groups of piles were flocked using an electrostatic flocking device (not shown). Afterwards, a plate 5' having holes 4', 4', etc. provided in a predetermined design above the flocked portion 9 is let, and the above-described process is carried out by blowing air 6 from above the plate 5'. The adhesive surface 7 is unevenly formed by the unevenly distributed air generated in the same manner as in the example, and the planting direction of the flocked piles 8 is also changed to a desired design.

In this way, unevenness is formed on the adhesive surface 7 by uneven air blowing, and the planting direction of the flocked piles 8 is changed, whereby a predetermined design is expressed on the flocked portion.

In addition, when expressing a sweeping design on the flocked part, the plate 5 (5') for unevenly distributed air blowing can be used with holes 4.4 (4) formed according to a design different from the above.
', 4'...) by simply replacing them with the drilled plates.

<Other Examples> The embodiments of the invention of this application are the above-mentioned each Example 1.
Of course, it is not limited to this, and for example, a variable flap or a baffle play 1. Various methods can be adopted, such as using a manifold or nozzle with a built-in bulkhead, or instead of these, moving an air gun having a small air outlet to draw the desired design.

In addition, the blown gas can accelerate adhesive coagulation or
It is also possible to use a mixture with a delay gas, or to use a coloring gas to give the pile group or adhesive a light hue.

<Effects of the Invention> As described above, according to the invention of this application, irregularities can be intentionally formed on the flocked surface without impairing the soft and luxurious texture of the flocked hair, and moreover, using the same workpiece, When manufacturing multiple types of flocked parts with different designs, it is only necessary to change the unevenly distributed blowing method, which has the excellent effect of greatly streamlining the manufacturing process. is played and enjoyed.
Furthermore, since the flocked area is formed into the desired design by blowing gas, the degree of unevenness can be adjusted by adjusting the strength of the gas blowing, which has the excellent effect of faithfully reproducing the desired design. Ru.
