METHOD FOR MANUFACTURING IMMEDIATE CUSTOM-MADE SHOE INSOLE USING 3D PRINTER [0001]

The present invention relates to a method for manufacturing and providing a customized sole shoe in a quieter and convenient manner in preparation for manufacturing a customized sole shoe according to a conventional CNC engraving production method.

In the conventional method of manufacturing a customized sole shoe, three-dimensional measurement is performed on the feet of different shapes for each person, the measured foot data is transmitted to a customized sole shoe manufacturing factory, and the foot of the customer is processed in the material prepared by the CNC engraver, It has been in the way of producing and providing unique customized sole shoes.

Conventionally, as shown in FIG. 4, a CNC carving machine 40 (upper image) is used to process a predetermined material (EVA, polypropylene, etc.) There was a way to complete it.

However, according to the conventional method of manufacturing a sole with a CNC carving machine, there is a merit that a large size of a CNC carving machine can be produced due to the presence of a large CNC carving machine. However, It is possible to manufacture only at a factory where there is no noise problem, and there is a problem that it is difficult to process at a shop where the customer is facing. In addition, there is also a problem that the air becomes cloudy due to the dust generated when the material is processed, so that the health of the worker is harmed and the cleaning is also difficult to clean. As a result, the CNC carving machine can not be provided in the store that responds to the customer, and the CNC carving machine is provided at other places in the factory. Therefore, a considerable amount of time is required between the shooting time There is a problem in that the efficiency of product supply is deteriorated.

An object of the present invention is to provide a method of manufacturing an instant shoe sole that measures the shape of the sole when ordering a customized shoe sole and can supply a customized product corresponding to the measured sole data instantaneously so as to eliminate a gap between a demand point of a consumer and a supply time point of the product .

It is another object of the present invention to provide a method of manufacturing an instant personalized sole that can be provided in a pleasant environment without noise and dust generated in a conventional CNC carving machine.

According to another aspect of the present invention, there is provided a method of manufacturing a personalized shoe sole, comprising the steps of: photographing a sole of a customer with a three-dimensional measuring device to obtain three-dimensional data of the sole; Editing the three-dimensional data of the sole with the customized sole shape data; Transmitting the edited personal sole shoe shape data to a three-dimensional printer, outputting a personalized sole window, and post-processing to complete the personalized sole shoe window; And providing the completed customized sole to the customer on the fly.

According to the instant method of manufacturing a sole according to the present invention, the shape of a foot of a customer can be measured by a three-dimensional measuring device, and a sole customized in the field can be immediately provided. Blank spaces between views can be eliminated.

In addition, since a three-dimensional printer with low noise is used, no processing noise and dust of the conventional CNC engraving machine are eliminated, so that it is possible to supply the customized shoe window to a customer instantaneously in a pleasant environment.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the method for manufacturing a shoe sole window according to an embodiment of the present invention, the foot of the customer is obtained by directly acquiring three-dimensional data (3D data) of the sole by using a 3D measuring device (3D Scanner). FIG. 2 is a view showing photographing the sole (left side) with the three-dimensional measuring device (right side), and an example of the three-dimensional measuring device is as shown in FIG. 1, And acquires the shape of the target surface in three dimensions (x, y, z). 1 (left side) in Fig. 1 is a three-dimensional measuring device (sock type) for obtaining three-dimensional data from the bending of the sole of the foot by photographing the sole with the sock drawn with stripes at regular intervals, Is a three-dimensional measuring device (form box type) for projecting a predetermined pattern onto a foam box on which a soles of a foot are pushed to obtain three-dimensional data from the shape of the pattern, and has been disclosed in the domestic market before the filing date of the present invention . The two kinds of three-dimensional measuring apparatuses of FIG. 1 are shown as one embodiment among various types of three-dimensional measuring apparatuses.

The three-dimensional measuring apparatus may photograph a bare bulb of a customer as it is, and a three-dimensional measuring apparatus (laser type) for obtaining three-dimensional data from bending caused by projecting a line laser on the sole. The three-dimensional measuring device of the present invention includes all three-dimensional measuring devices capable of obtaining three-dimensional data of the sole.

The three-dimensional data of the sole obtained after photographing the sole using the three-dimensional measuring device is as shown in Fig. In Fig. 3, sole data is expressed in different colors depending on the depth. These three-dimensional data of the sole can be represented by points, triangle mesh, color, texture, and the like. The 3D data has a variety of 3D file formats (3D file format), and STL (StereoLithography) files are mainly used as a compatible 3D file format.

Since the obtained three-dimensional data of the sole is inconvenient to manufacture as the original data of the photograph taken, it is difficult to wear it. Therefore, it is necessary to use a predetermined software having a CAD function so that the customer can wear the three- . Three-dimensional data with this final shape is shown in Figs. 5 and 6. Fig. FIG. 5 is a full length version edited to the tip of the toe, and FIG. 6 corresponds to a half length edited in a form up to the important portion of the sole.

Thus, the three-dimensional data of the soles of which the editing is completed are transmitted to the 3D printer.

In the present invention, a 3D printer refers to a device that receives three-dimensional data and produces an actual three-dimensional shape by the same size (or enlargement or reduction). In a recently used three-dimensional printer, a device for transferring three-dimensional data to melt a solid material with a high temperature and pushing or spraying the solid material through a nozzle to form a three-dimensional layer so as to form an actual three-dimensional shape is used. It is often used in prototyping and is different from a CNC engraver that cuts material with a high-speed rotating end mill. 3D printers have recently become smaller, cheaper, and more popular. In the embodiment of the three-dimensional printer, since the material melted by high heat is stacked up, there is an advantage that the conventional CNC engraving machine does not generate any great noise and dust generated when processing a hard material. Fig. 7 shows a three-dimensional printer of a basic shape and one pair or one foot (one foot, left foot, or right foot) of a customized sole that is output therefrom. Conventional CNC engraving machines have been difficult to store in stores due to noise and dust. The 3D printers can be operated quietly and cleanly. Recently, many miniaturized desktop 3D printers have come to be available in stores.

The 3D printer according to the present invention includes a device having a similar function as a core that receives three-dimensional data and generates an actual three-dimensional shape without loud noise.

In order to speed up the production of the customized shoe sole, two or more 3D printers are provided. As shown in the lower right part of Fig. 7, each of the three-dimensional printers has a sole (one for the left foot and one for the right foot) To reduce the required time to 1/2, which is a preferred embodiment for increasing the productivity. The material (material) used in one embodiment of the three-dimensional printer may be a transparent material such as transparent acrylic, an opaque material such as ABS, PLA (Polylactic acid, Polylactide), an elastic material such as polypropylene Various materials such as a material, a rubber material, and a powder material can be used. The manufacturing method includes a nozzle melting method, a laser melting method, a powder projection bonding method, and the like.

As a preferred embodiment of the material of the three-dimensional printer, actually used polylactide may be used.

As a preferred embodiment of the material of the three-dimensional printer, a flexible polypropylene or a material having a similar material can be used.

Since the output of the 3D printer is the output material, a simple grinding operation, post-processing such as attaching the opposite surface of the sole to the sole and the shoe to the leather or vinyl, So that it can be provided to the customer on the spot. Figure 8 shows the final finished form of the customized sole.

Such a customized sole has conventionally required a considerable amount of time between the shooting point of the sole of the customer (point of time of ordering) and the point of completion of the production of the customized sole according to the measured bar (point of time of delivery) The method of manufacturing instant shoe sole according to the present invention can provide a customized shoe window with a three-dimensional printer at the time of a customer's order, thereby providing a method of overcoming the conventional demand limit.

Meanwhile, since the method of manufacturing the instant personalized shoe sole described above is only one embodiment for facilitating understanding of the present invention, it is difficult to interpret the scope of the present invention and the technical scope thereof as being limited to the above.

The scope of the present invention is defined by the appended claims and their equivalents.
