1 and 2 will be described a method of manufacturing a shoe sole 10 according to the present invention.

In the step (a), the surface of the rubber plate 11 is polished, followed by a washing process of removing impurities and adhesion inhibitors from the surface, and the surface of the rubber plate 11 is finely prepared with a thinner and an adhesive reinforcement agent. It is a pretreatment step of melting.

The rubber plate 11 may be applied to a hard rubber or urethane material having a cushion while having elasticity, it is preferable to use a molded of styrene butadiene rubber (SBR) excellent in durability and weather resistance, wear resistance, etc. Do.

Surface polishing of the rubber plate 11 is scratched and polished the surface using a paper, washed with air or water during the cleaning process, the surface of the polished rubber plate 11 so that a defective rate according to the adhesion state in the next step is not generated Removes impurities and chemicals such as mold release agents (chemical and oil components) and the pretreatment agent is to improve the adhesion efficiency by allowing the adhesive to penetrate well.

Step (b) attaches the protective paper 12 having the adhesive surface to the surface of the rubber plate 11 to process the sole plate.

The protective paper 12 uses a very thin plastic paper, the adhesive surface formed on one surface has a sticky adhesive force by applying a special adhesive usually used for post-it, and easy to attach and detach.

The protective paper 12 protects the surface of the rubber plate 11 in a subsequent step, and also forms a negative portion 16 by a laser processing apparatus. 17) to make it possible to meet all of the functions to facilitate the forming work.

The sole plate is in the form of a rectangular plate having a size to produce a pair of shoe soles (10).

Step (c) takes the sole plate and processes the shoe sole 10 in the form of a chief like the sole of a high heel sandal, using a potter's wheel or computer cutting to fit the shape of the sole of the shoe.

As illustrated in FIG. 1, the shoe sole 10 manufactured through this step is in a state in which the protective paper 12 is attached to the surface of the rubber plate 11.

On the other hand, it is preferable to further include the step (a) and (b) to (f) in the above-described manufacturing method.

In the step (f), the urethane film 13 having the color is prepared, the adhesive is applied to the surface of the pretreated rubber plate 11 to pass through a drying furnace to maintain the viscosity of the adhesive properly, and the urethane film 13 After adhering to the surface of the rubber plate 11, it is pressurized with a roller can be processed to the sole main plate in which the rubber plate 11 and the urethane film 13 is combined.

Looking at the manufacturing method of the urethane film 13 having a color, spreading the oil paper rolled in the form of a roll to apply a thin urethane liquid having a color (about 0.5mm ~ 1mm). After the applied urethane liquid is cured, the oil paper is removed to complete the urethane film.

Next, the adhesive is applied to the surface of the pretreated rubber plate 11 to pass through a drying furnace at 80 to 100 ° C. so that the adhesive maintains an appropriate viscosity (a time point at which the adhesive ability is exerted), and the urethane film ( 13) is bonded to the surface of the rubber plate 11, and then pressurized with a roller to obtain a sole main plate in which the urethane film 13 is laminated on the surface of the rubber plate (11).

Here, the finished shoe sole 10 is subjected to an aging process that is left for a certain time at a constant temperature in order to increase the adhesiveness of the rubber plate 11 and the urethane film 13, by layering the finished shoe sole 10 When the process of pressing the weight of about 24 hours to pressurize, the sole 10 of the urethane film 13 is incorporated into the rubber plate 11 is manufactured, as shown in Figure 2 the urethane film 13 on the surface of the rubber plate 11 ) Is completed, and the manufacturing of the shoe sole 10 with the protective paper 12 attached thereto is completed.

With the shoe sole 10 completed through the above steps, steps (d) and (e) are sequentially performed.

Step (d) will be described further comprises the shoe sole 10 shown in Figure 1 completed through the steps (a) to (c) described above and the shoe shown in Figure 2 completed further comprising (f) All can be applied to the sole 10.

3 to 5, the urethane film 13 is laminated on the surface of the rubber plate 11, and the shoe sole 10 having the protective paper 12 attached thereto is illustrated in the drawings, with reference to the drawing. It will be described in detail the manufacturing method to proceed, and the method of manufacturing with a shoe sole attached with a protective paper 12 on the surface of the rubber plate 11 is considered to be sufficiently understood without a separate description, so the description thereof will be omitted. Let's first find out.

Step (d) is to irradiate a laser beam on the surface of the protective paper 12 attached to the shoe sole 10 by using a laser processing apparatus to burn a portion corresponding to the pattern 15 so as to have a predetermined depth on the surface of the rubber plate 11. To form the intaglio portion 16 to have.

3 is a view for explaining a shoe sole manufacturing method according to the present invention, a cross-sectional view showing a laser processing process.

The laser processing apparatus includes a laser oscillator for irradiating a laser beam to a work table, a shoe sole 10 placed on the work table, and a laser oscillator to the plane of the work table according to a control signal installed on an upper frame. And a controller for controlling the driving of the position transfer means and the laser oscillator.

The controller is composed of a computer equipped with a monitor and various input / output devices, and when the user sets a variety of patterns such as a flat design, that is, a mark, a character, various figures or a trademark, and outputs coordinates thereof to the transfer means, the transfer means. The laser oscillator is moved by the laser oscillator, and the laser oscillator irradiates the laser beam while moving to the coordinates (flat design form) output from the controller.

In addition, the controller may control the operating state of the laser oscillator as well as adjust the intensity of the output laser beam according to the input state.

The process of processing various patterns 15 on the shoe sole 10 using such a laser processing apparatus will be described in detail as follows.

First, the protective paper 12 attached to the shoe sole 10 to be processed is placed on the work table of the laser processing apparatus with the protective paper 12 upward, and then the laser oscillator and the transfer means for the predetermined flat design desired by the operator through the controller. To control the operation. Then, the laser oscillator is moved by the transfer means according to the set flat design shape, and at the same time, the laser beam irradiated from the laser oscillator touches the surface of the protective paper 12 and the protective paper 12 and the urethane film by the heat of the laser beam. By burning the irradiation part of (13), the intaglio part 16 is formed in the surface of the rubber plate 11 by the desired pattern 15 to a predetermined depth.

Here, the depth of the intaglio portion 16 is determined by the intensity of the laser beam, if the depth including the thickness of the urethane film 13 is acceptable. Even in the case of the rubber plate 11 in which the urethane film 13 is not incorporated, it may be formed to such a depth. Of course, although the intaglio portion 16 may be formed deeply in the rubber plate 11 through the urethane film 13, the durability of the rubber plate 11 due to the deep indentation portion 16 when used by attaching to the bottom of the shoe. It is not suitable because it can fall.

Finally, the step (e) is applied to the area corresponding to the entire intaglio portion 16 formed on the protective paper 12 using a coating material to harden to some extent, and then the protective paper 12 is removed and removed. . Then, as shown in FIG. 5, the paint layer 17 remains on the intaglio portion 16 formed on the surface of the rubber plate 11.

When using the laser processing apparatus, even if the pattern 15 to be implemented is very complicated, as shown in FIGS. 6, 7 and 8, very fine and sophisticated patterns can be realized, and the work is very easy, so that a large amount of shoe soles can be obtained. Emblem can be embodied quickly in (10).

As a paint used to form the paint layer 17, a rubber or silicone material having a color may be used, and a method of forming the paint layer 17 may be selected, and other general paint may be used as a paint. Of course. In addition, the color of the paint layer 17 is preferably different from the color of the urethane film 13 so as to be clearly distinguished.

When using the lacquer (cellulose paint), it is efficient to spray, or spray, the coating layer is hard, non-adhesive, excellent in abrasion resistance, water resistance, oil resistance, and hardening time. This has the advantage of providing a very fast and robust coating.

On the other hand, in Figure 5, the surface of the paint layer 17 and the urethane film 13 is shown to match, but in the case of using lacquer as a paint is completely solid and penetrates into the rubber plate 11 partly so that the urethane film 13 The paint layer 17 is formed to be lower than the surface of) so that in the final state, the paint layer 17 has irregularities due to the intaglio portion 16.

In addition, when rubber or silicone is used as the paint, the paint layer 17 may be formed to protrude convexly from the intaglio portion 16 or may have irregularities accordingly.

When the pattern 15 is formed as shown in FIG. 6, the uneven or painted layer 17 formed by the intaglio portion 16 protrudes convexly, and has a convex unevenness at a portion of the shoe sole 10 that contacts the ground. Since the frictional force is increased by forming the uneven portion, it is also possible to obtain the effect of preventing slipping.

The shoe sole 10 manufactured according to the present invention does not specify the type of shoes to be used, but may be particularly applicable to high heel sandals.

The high heel sandals attach the shoe sole 10 to the front part of the sandals in a state where the heel is coupled to the bottom, and bend the portion connected to the back of the shoe sole 10 to closely adhere to the inner part of the heel. Is done.

As described above with reference to the drawings for the shoe sole manufacturing method and shoe sole using the same according to the present invention as described above, the present invention is not limited by the embodiments and drawings disclosed herein, the present invention Of course, various modifications may be made by those skilled in the art within the scope of the idea.
