DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an apparatus and a method for manufacturing an insole support buried in an insole.

[0002]

2. Description of the Related Art Conventionally, shoes such as bumps, loafers, business shoes, sports shoes, and sandals have been provided with an insole for the purpose of absorbing shock, deodorizing and deodorizing, or for healing hallux valgus. ing.

[0003]

These insoles are made by cutting the insole material to fit the size of the sole, and are not made to order and do not fit each orderer. Tired of
It is hard to say that it serves the purpose of relieving pain.

[0004] Insoles are also manufactured on a bespoke basis.
Production is troublesome. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a manufacturing apparatus and a manufacturing method of an insole support used for manufacturing an insole that is made to order and is made to order. is there.

[0005]

According to a first aspect of the present invention, there is provided an apparatus for manufacturing an insole support, comprising: heating means for heating an insole support material made of a thermoplastic resin material at a predetermined temperature for a predetermined time; The insole support material applied to the sole including the sole is pressed with the foot for a certain period of time, and has a sponge cushion means for retaining the shape of the last.

As the insole support material, it is preferable to use a copolymer of polyethylene and vinyl acetate or polypropylene, polyethylene or thermocork. It is more preferable to use a copolymer of polyethylene and vinyl acetate. It is even more preferable from the viewpoint of cost and ease of molding.

It is preferable to use a polyurethane or silicone resin foam or an ethylene propylene copolymer for the sponge cushion means. When the heating temperature of the insole support material is less than 130 ° C., it is difficult to deform, and when it exceeds 160 ° C., it feels hot when applied to the soles. It is desirable that

According to a fifth aspect of the present invention, there is provided a method for manufacturing an insole support, comprising the steps of: holding a flat insole support material made of a thermoplastic resin material and heated at a predetermined temperature for a predetermined time; The insole support material is manufactured by deforming the insole support material by pressing against the cushion means while being applied to the sole, and copying the shape of the sole.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. First, as shown in FIGS. 1A and 1B, an insole support material 1 is prepared. The material of the insole support material 1 is a thermoplastic resin such as a copolymer of polyethylene and vinyl acetate (EVA), polypropylene (PP), polyethylene (PE), or a thermo-deformable thermocork. The cross-sectional shape of the insole support material 1 before processing is flat as shown in FIG. Here, a copolymer of polyethylene and vinyl acetate (EVA: Vickers hardness 50 kg to 120 kg / square cm) is used as the material of the insole support material 1 from the viewpoint of low cost and ease of molding. If natural rubber or synthetic rubber is used, it melts or burns at this heating temperature and is not suitable for use in molding.

The insole support material 1 is placed in an oven 2 as a heating means, and is heated from 130 ° C. to 160 ° C.
Heating is performed for a predetermined time within a predetermined temperature range up to the temperature C and in a range from 30 seconds to 3 minutes. If the heating temperature is lower than 130 ° C, it is difficult to deform, and if the heating temperature is higher than 160 ° C, it feels hot when applied to the soles.
To 160 ° C. Thereby, the insole support material 1 is softened and easily deformed.

The heated insole support material 1 is taken out of the oven 2 and, as shown in FIG. 2, is applied to the sole 4 on which a custom-made insole is to be produced, and the memory is used as a sponge cushion means. Pressed against Form 3. The material of the memory foam 3 has a shape-retaining property (a property of being deformed at the initial stage of applying pressure and thereafter maintaining the deformed shape even after a lapse of time), for example, a polyurethane or silicone resin-based material. A foam or an ethylene propylene copolymer is used.

At this time, the orderer of the bespoke insole rides on the memory foam 3 with the insole support material 1 resting on the sole 4 in a natural posture in a standing position, or supports the insole while sitting on a chair. Put body material 1 on sole 4 and put foot 5 on memory form 3
Time until the insole support material 1 cools down and its shape is fixed, for example, 1 minute. Maintain the same posture for ~ 5 minutes.

Thus, the last is copied to the insole support material 1 and the insole support 6 shown in FIG. 3 is manufactured. Using this insole support 6, an insole 7 that fits each orderer is manufactured as shown in FIG. In FIGS. 3 and 4, the raised portion indicated by reference numeral 6 a is a portion corresponding to the arch.

As described above, according to this apparatus for manufacturing an insole support, a step of heating the flat insole support material 1 made of a thermoplastic resin material at a predetermined temperature for a predetermined time, And the step of pressing the insole support material 1 applied to the sole 4 together with the foot against the memory foam 3 for a certain period of time to retain the last. The insole support 6 can be manufactured by a simple manufacturing process, and the insole support 7 in which the insole support 6 is embedded and fits each customer can be manufactured by a simple process.

[0015]

According to the present invention, an insole support that fits each orderer can be manufactured by a simple process, as compared with a case where a last is made of gypsum.
