Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stack heel stack that can be easily and accurately manufactured, a stack heel, and a manufacturing apparatus therefor. The stack heel described in the present invention includes a unit sole integrated with the outsole.

[0002]

2. Description of the Related Art Conventionally, a stack heel, which is a component of a shoe, is generally manufactured by first forming a heel body having a desired shape by using a plastic material such as wood or ABS resin.

Then, the laminated leather is press-molded so as to fit the shape of the heel body, and sliced to make a laminated leather, and the laminated leather is wrapped around each heel body and attached, and the rit is attached. .

Then, a hardener is applied to the leather, and the hardened leather is carefully polished with a polishing paper, colored with a paint, and then polished with wax to finish.

[0005]

However, in the production of such a conventional stack heel, for example, the leather 2 wound around the heel body 1a having a three-dimensional shape having a complicated curved curve is formed by hand. It is evenly polished by work and polished with wax. It is very difficult to uniformly grind and polish the three-dimensional heel body 1a, and a large number of skilled engineers having such a technique are required, and FA (work factory automation) is required for work.
However, there is a problem that the accuracy of manufactured products is large and the product yield is low.

This poor product yield is caused by frequent polishing unevenness and color blurring due to polishing with wax, for example, and the durability is not so good, and color change occurs due to heating and humidification in the finishing process. , In the worst case, it may cause color transfer to the shoe body.

On the other hand, with the aging of skilled technicians in this kind of field in recent years, it has become difficult to secure and train new skilled technicians due to changes in the industrial structure, and further mass production of products is required.

The present invention has been made in view of such circumstances, and it is possible to easily and accurately manufacture a stack leather for a stack heel and a stack heel having a three-dimensional shape without requiring a skilled technique. An object of the present invention is to provide a stackable leather for stack heels, a stack heel and a manufacturing apparatus therefor.

[0009]

In order to achieve such an object, the present invention has a plurality of piles of leather to be attached to a heel body which has been previously cured, and is attached to a pedestal in a flat plate shape so as to be peelable. In addition, it is characterized in that the surface of the plurality of leather layers is polished.

[0010] Further, the leather which has been hardened in advance and made into a flat plate shape and whose surface has been polished is wound around the heel body and attached thereto, and the surface of the leather is subjected to a coloring treatment with a UV paint or the like. It is characterized by applying.

Further, a pedestal for attaching a plurality of leather layers to be attached to the heel body, which has been cured in advance, in a flat plate shape and capable of being peeled off, and an automatic polishing machine for polishing the surface of the plurality of leather layers. It is characterized by doing.

[0012]

According to the present invention, since the leather is cured and automatically flattened in the step before the leather is wound around the three-dimensional heel body, the conventional method is used. The stack heel is easily and accurately manufactured without requiring a skilled technique of manually polishing the surface of the laminated leather manually after winding the laminated leather around the heel body.

[0013]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows an example of a heel body used for carrying out the present invention. The heel body 10 is formed of a plastic material such as wood or ABS resin,
The outer peripheral surface is molded as a three-dimensional design having curved curves.

Next, what is shown in FIG. 2 (a) is a laminated leather 11 which is wound around the heel body 10 and adhered thereto,
Although not shown, the laminated leather is press-molded according to the shape of the heel body to be wrapped and sliced. Moreover, the leather 11 has already been hardened.

This hardened leather 11 is shown in FIG.
As shown in (b), a plurality of sheets are releasably attached to the pedestal 12 of the manufacturing apparatus via an adhesive (not shown) applied to the back surface at regular intervals.

Then, as shown in FIG. 2 (c), the laminated leather 11 attached on the pedestal 12 rotates endlessly and has an abrasive 13a attached so as to be vertically movable. The surface is automatically polished by the device 13. As the abrasive 13a, for example, sanding paper or the like is used, and after rough polishing (# 180 paper) in the first step (left side in the figure), finish polishing (# 180 paper) in the second step (right side in the figure). # 280 Paper, # 32
0 paper).

Thereafter, the polished leather 11 is peeled off from the pedestal 12, wound around the heel body 10 and affixed, and the rit 14 is attached, as shown in FIG. 2 (d).

Thereafter, the wound leather 11 which is the completed stack heel is colored with a urethane paint which is a UV paint and dried to form a shoe as shown in FIG. 3 (a). The stack heel 15 completed as a part is produced. In addition, what was shown to the same figure (b) has shown an example of the stack heel which has another shape.

FIG. 4 shows a stack heel finishing device 20 which is used after the leather 11 is wrapped around and adhered to the heel body 10. As shown in FIG. After coloring with a brush, the stack heel is placed on the conveyor belt 22 from the starting end side (left side in the drawing) of the apparatus 20.

Then, the auxiliary heater 21 for drying and the cross fan 22 are moved while being dried, and the UV curing unit 24 on the terminal side (right side in the drawing) carries out the final curing treatment. This UV dryer 24 is shown in FIG.
As shown in (c), a pair of left and right UV lamps 24a, an air outlet 24b, and an aluminum reflector 24c are provided. In addition, 25 is an exhaust blower, 26 is a blower blower,
27 is a filter.

As described above, according to this embodiment, in the process before winding the leather 11 around the three-dimensional heel body 10,
Compared with the conventional method in which the surface of the leather 11 is evenly polished and hardened after the leather 11 is wound around the heel body 10 because the leather 11 is hardened and automatically polished as a flat surface. Thus, the stack heel can be manufactured easily and accurately without requiring any skill.

[0022]

As described above, according to the present invention, a stack heel having a three-dimensional shape can be easily and accurately manufactured, and a stack heel can be manufactured with good mass productivity even by a skilled engineer. It can be carried out.
