DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0023] The technical characteristics, contents, advantages and
effects of the present invention will be apparent with the detailed
description of a preferred embodiment accompanied with related
drawings as follows. The drawings are provided for the
illustration, and same numerals are used to represent respective
elements in the preferred embodiments. It is intended that the
embodiments and drawings disclosed herein are to be considered
illustrative rather than restrictive. Same numerals are used for
representing same respective elements in the drawings.
[0024] With reference to FIGS. 1 to 3 for an exploded view, a
schematic view and a cross-sectional view of shoes of an automated
process production of the present invention respectively, the shoes
of an automated process production 1 comprises a shoe-upper
material 11, a shoe sole 12 and a plastic material 13. The
shoe-upper material 11 is a one-piece three-dimensional structure
and includes a shoe-upper 111 and a footrest underside 112. The
shoe-upper 111 is coupled to the footrest underside 112 along an
edge of the footrest underside 112 and provided for covering a
portion of a wearer's foot. The shoe sole 12 is installed at the
footrest underside 112. The plastic material 13 is coated onto the
shoe-upper 111 and the footrest underside 112 and filled between
the footrest underside 112 and the shoe sole 12, and the shoe sole
12 is glued to the footrest underside 112 by the plastic material
13. The plastic material 13 forms at least one support member 131
attached onto the shoe-upper 111 and the footrest underside
112.
[0025] In addition, the shoe-upper material 11 is a one-piece
three-dimensional braid, but the invention is not limited to the
braid only, but any other equivalent material such as leather can
be used instead. Since the shoe-upper material 11 is formed by a
weaving method, and weaving threads are usually not closely woven,
therefore the shoe-upper material 11 has a plurality of pores
113.
[0026] When the melted plastic material 13 is coated onto the
shoe-upper 111 and the footrest underside 112 of the shoe-upper
material 11, the plastic material 13 is covered onto the shoe-upper
111 and the footrest underside 112 of the shoe-upper material 11
and also permeated into the plurality of pores 113 of the
shoe-upper material 11, After the plastic material 13 is cured
gradually within a period of time the plastic material 13 permeated
into the plurality of pores 113 is cured to connect and seal each
pore 113, so that the plastic material 13 can be attached tightly
onto the shoe-upper material 11.
[0027] However, the shoe-upper material 11 is a braid with
insufficient supporting force to support its own weight and the
shoe-upper material 11 is a three-dimensional form, so that when
after the plastic material 13 is cured, the plastic material 13 has
a specific hardness to become a three-dimensional structured
support member 131 for supporting the shoe-upper material 11, and
the framework of the shoe-upper material 11 is generally attached
onto an external surface (including the shoe-upper 111 and the
footrest underside 112) of the shoe-upper material 11 to provide a
supporting force to the whole shoe-upper material 11 and support
the shoe-upper material 11 in a three-dimensional form.
[0028] Beside providing the supporting force to the shoe-upper
material 11, the support member 131 also has other functions, such
as the adjustment of the mold according to the design requirements
during the manufacture, so that when the plastic material 13 is
injected to the shoe-upper material 11, the plastic material 13
forms a stylish form corresponding to the mold on the shoe-upper
material 11, and the plastic material 13 has a specific shape on
the shoe-upper material 11, and the color of the plastic material
13 is selected to match with the color of the shoe-upper 111 while
completing the coloring operation. The invention can save the
manufacturing cost and time effectively. For example, the
conventional shoemaking methods require attaching the stylish parts
one by one onto the shoe-upper material 11, and some methods even
require a sewing process to fix the parts. Now, the present
invention injects the plastic material 13 directly to form the
parts onto the shoe-upper material 11, not only achieving a better
attachment of the parts with the shoe-upper material 11, but also
saving the manpower and manufacturing time required for the
attaching and sewing operations effectively.
[0029] It is noteworthy that the shoe-upper material 11 cannot
support itself before the manufacture, so that it is necessary to
use a shoe shaped inner mold 14 installed inside the shoe-upper
material 11 to provide a supporting force during the manufacture.
The detailed description of the shoemaking method of an automated
process production is given below.
[0030] Even though the concept of shoemaking method of an automated
process production of the present invention has been described in
the process of describing the shoes of an automated process
production of the present invention, the following flow charts are
provided to give a more detailed description of the shoemaking
method.
[0031] With reference to FIGS. 4 and 5 for the flow charts of a
shoemaking method of an automated process production and a gluing
step of the shoemaking method of an automated process production in
accordance with the present invention respectively, the shoemaking
method of an automated process production of the invention
comprises the following steps:
[0032] S11: Providing a one-piece three-dimensional structured
shoe-upper material, wherein the shoe-upper material includes a
shoe-upper and a footrest underside, and the shoe-upper is coupled
to the footrest underside along an edge of the footrest
underside.
[0033] S12: Providing a shoe sole, installed at the footrest
underside and disposed at a position corresponding to the footrest
underside.
[0034] S13: Coating a plastic material onto the shoe-upper and
footrest underside and filling the plastic material between the
footrest underside and the shoe sole by a gluing step to glue the
shoe sole to the footrest underside.
[0035] S14: Forming at least one support member attached onto the
shoe-upper and the footrest underside by the plastic material to
support the upper material.
[0036] In addition, the gluing step further comprises the following
steps:
[0037] S131: Setting the shoe-upper material onto a shoe shaped
inner mold, wherein the shoe shaped inner mold can be a movably
stretchable shoe last, and adjust the size of the shoe-upper
material to fit different sizes of shoes.
[0038] S132: Putting the shoe-upper material and the shoe sole in a
shaping mold body having at least one preset mold cavity, and
pressing the shoe-upper material by the shaping mold body, wherein
the shaping mold body includes at least three movable shaping mold
blocks having the at least one preset mold cavity. For example,
this embodiment adopts three mold blocks for pressing both sides of
the shoe-upper and the footrest underside respectively, but the
quantity of mold blocks is not limited to three but it can be
adjusted according to actual requirements. It is noteworthy to
point out that the shoe sole is placed onto one of the mold blocks
corresponding to the footrest underside.
[0039] S133: Injecting a plastic material into the at least one
preset mold cavity of the shaping mold body by a plastic injection
molding machine to coat the plastic material onto the shoe-upper
and the footrest underside and fill the plastic material between
the footrest underside and the shoe sole.
[0040] S134: Removing the shoe shaped inner mold and the shaping
mold body by a demolding step.
[0041] Before the demolding step takes place, the shoemaking method
of the invention further comprises the following steps:
[0042] S1331: Permeating the plastic material into the plurality of
pores of the shoe-upper material to connect the plastic material to
the shoe-upper material.
[0043] S1332: Waiting till the plastic material is cured and
shaped, the plastic material forms an intermediate glue layer
between the footrest underside and the shoe sole to glue the shoe
sole to the footrest underside.
[0044] For short, the shoe-upper material and the shoe sole are
placed into predetermined positions in the mold, and then an
injection molding method is used to inject the melted plastic
material into the mold and shape and cure the plastic material in
the mold, while the plastic material is tightly fixed onto the
shoe-upper material, and the shoe sole is also tightly fixed onto
the plastic material of the footrest underside. Therefore, the
manufacturing process can be simplified to facilitate the
manufacture, and the plastic material can be used effectively to
support the shoe-upper material and fix the shoe sole, while giving
a decorative effect.
[0045] The detailed description and implementation of the
shoemaking method of an automated process production of the present
invention have been described previously in the section of the
shoes of an automated process production of the present invention,
and thus will not be repeated.
