Description

Technical Field [0001] The present invention relates to an induction heating apparatus for bonding a three-dimensional object, a shoe manufacturing apparatus using the same, and a shoe manufacturing method using the same.

The present invention relates to an induction heating apparatus, a shoe making apparatus and a shoe making method using the induction heating apparatus, and more particularly, to an induction heating apparatus, a three-dimensional object bonding method, A footwear manufacturing apparatus using the same, and a footwear manufacturing method.

Generally, the shoe is largely composed of an upper and a sole, and the sole is made up of an outsole, a midsole, and an insole. Each part is made through each manufacturing process and then assembled with an adhesive. Therefore, the shoe manufacturing process can be divided into the parts manufacturing process and the assembling process of assembling these parts.

In addition, shoe materials are typical nonpolar materials and adhesion is very difficult, so various pretreatment processes are required. The pretreatment process is a pretreatment process before applying an adhesive to bond shoe parts composed of an outsole, a midsole and an upper part. The cleaning is a process of removing contaminants such as a mold release agent on the surface of each component . For example, the ultraviolet treatment process changes the surface of a material by a chemical method, and the primer is an indispensable process for enhancing adhesion force to be used for enhancing the bonding force with an adhesive.

 Conventional wet adhesive heating method uses hot air, which causes damage to the material at high temperature by applying energy to the front side of the material after the adhesive is applied. That is, a conventional wet adhesive needs to be dried after application, and a material sensitive to the drying temperature may cause a change in physical properties. In particular, in the case of midsole, problems such as dimensional stability arise when the drying temperature is higher than 60 ° C.

Also, existing wet adhesives require a post-application drying process, and existing shoe bonding processes are produced through a preparation process and a finished adhesive process, which complicates the production process.

In addition, when the adhesive surface of the shoe material parts has a curvature, the heat transmitted to the adhesive agent is not uniform, so that the adhesive strength varies over the entire adhesive surface, thereby deteriorating the reliability of the product.

Hereinafter, preferred embodiments of the present invention in which the above-mentioned problems to be solved can be specifically realized will be described with reference to the accompanying drawings. In describing the embodiments, the same names and the same symbols are used for the same configurations, and additional description therefor will be omitted below.

1 to 4, an induction heating apparatus for three-dimensional object bonding according to an embodiment of the present invention and an apparatus for manufacturing shoes using the same will be described.

The shoe manufacturing apparatus according to the present embodiment includes an induction heating apparatus for adhering a three-dimensional object such as a first object 110 having a curved surface and a second object 120 to be adhered, A conveying unit 400 for conveying the three-dimensional objects into the induction heating space of the apparatus 100, and a pressing unit (not shown) for pressing the bonded three-dimensional objects.

The first adhesive object 110 corresponds to the outsole constituting the shoe sole 100 and the second adhesive object 120 corresponds to the midsole constituting the shoe sole 100. [ At this time, since the upper surface of the outsole or the lower surface of the midsole forms a non-flat curved surface, the adhesive layer also has a curved surface.

However, the present invention is not limited to this, and the first object 110 and the second object 120 may be three-dimensional objects having curved surfaces and may be included in any non-metallic material. For example, the first object to be bonded may correspond to a midsole of a shoe, and the second object to be bonded may correspond to a top of a shoe.

In addition, any one of the first bonding object 110 and the second bonding object 120 may have a curved surface.

The adhesive layer 130 disposed between the first bonding object 110 and the second bonding object 120 includes metal particles 131 and an adhesive 133.

The adhesive layer 130 may be provided in the form of a single adhesive film or may include a first adhesive layer applied to the first adhesive object and a second adhesive layer applied to the second adhesive object It might be.

For example, an adhesive film is disposed between an outsole and a midsole in the process of manufacturing a shoe sole, and the metal particles contained in the adhesive film are heated using the induction heating device to activate the adhesive component contained in the adhesive film So that the outsole and the midsole can be adhered to each other.

Further, in the process of manufacturing the shoe sole, the outsole having the first adhesive layer applied thereto, and the induction heating device with the first adhesive layer and the second adhesive layer opposed to each other with respect to the midsole coated with the second adhesive layer, The metal particles contained in the first adhesive layer and the second adhesive layer may be heated by using the apparatus to activate the adhesive component contained in the adhesive layer, thereby bonding the outsole and the midsole.

The first adhesive layer and the second adhesive layer may be applied to the outsole and the midsole, respectively, by spraying.

The metal particles 131 are uniformly distributed throughout the adhesive layer 130, and the metal particles may be nickel or the like. In addition, the adhesive 133 is activated when heat is supplied, and has an adhesive force.

FIG. 3 is a graph showing the definition of a volume fraction when metal particles are distributed in a certain space, and FIG. 4 is a graph showing a degree of heating versus frequency according to various volume fractions.

Referring to FIG. 4, it can be seen that the larger the volume fraction is, the higher the volume fraction of the alternating current at a specific frequency is, the better the heating is. Also, in the case of having the same volume fraction, the larger the frequency is, the better the induction heating is.

The three-dimensional object bonding induction heating apparatus heats the metal particles 131 of the adhesive layer 130 disposed between the curved surface of the first bonding object 110 and the second bonding object 120 Thereby forming a magnetic field in the induction heating space.

Specifically, the induction heating apparatus includes an induction coil unit 200 for generating a magnetic field, an inverter unit 300 for providing an alternating current to the induction coil unit 200, And a wire unit 500 for connecting the unit 300 to each other.

When an AC current is supplied to the induction coil of the induction coil unit 200 by the inverter unit 300, a magnetic field is formed in a region adjacent to the induction coil, that is, in the induction heating space.

When the laminated object to be bonded, on which the first object 110 and the second object 120 are laminated, is placed in the induction heating space via the curved adhesive layer 130, Induced current, for example, eddy current, is generated in the distributed metal particles 131, thereby generating heat according to the Joule's law.

The adhesive 133 around the metal particles 131 is heated by the heat of the metal particles 131 to bond the first adhesive object 110 and the second adhesive object 120 together.

As a result, the induction heating apparatus according to the present embodiment minimizes heat loss by heating only the adhesive 133 in a state in which the first bonding object 110 and the second bonding object 120 are not heated directly, The thermal deformation of the objects to be bonded can be prevented.

The induction coil unit 200 may be installed in the induction coil unit 200 such that the temperature of the adhesive layer 130 due to the heating of the metal particles 131 is within the allowable temperature range over the entire adhesive layer 130, And a second induction coil part 220 disposed at a predetermined distance apart in a downward direction of the second object to be bonded.

In order to form a magnetic field having a uniform intensity on the induction heating space, the first induction coil part 210 and the second induction coil part 220 have the same shape and size and are formed on the basis of the adhesive layer 130 And are arranged symmetrically.

Here, the first induction coil part 210 is connected to the inverter unit 300 by the first connection wire 510 of the electric wire unit, and the second induction coil part 220 is connected to the first induction coil part 210 of the electric wire unit 2 connection wire 520 to the inverter unit 300.

The first induction coil part 210 includes a first base member 211 having a flat plate shape and a first induction coil 213 disposed on the first base member 211.

It is needless to say that the present invention is not limited to the above-described embodiment, and the first induction coil part 210 may be configured such that a magnetic field generated by the first induction coil 213 is transmitted to the first induction coil part 210 in a direction That is, to be formed only in the downward direction.

In order to form a magnetic field of uniform intensity on the induction heating space, the installation area of the first induction coil 213 is formed larger than the projected area of the objects to be bonded.

If the area of the first induction coil 213 is larger than the area of the object to be bonded, the area of the induction current generated by the first induction coil 213 is uniform, Can be uniformly heated.

As a result, even if the adhesive layer 130 has a curved surface along the first adhesive object 110, the adhesive layer 130 is uniformly heated, so that the first adhesive object 110 and the second adhesive The object 120 is adhered with a uniform adhesive strength over the entire surface of the adhesive layer 130, thereby increasing the reliability of the product.

Similarly, the second induction coil part 220 includes a second base member 221 having a flat plate shape and a second induction coil 223 provided on the second base member 221. Since the second induction coil part 220 is substantially the same as the first induction coil part 210, detailed description thereof will be omitted.

It is needless to say that the present invention is not limited to this, and the magnetic field formed by the second induction coil 223 of the second induction coil part 220 may be changed in a direction in which the second object to be adhered 120 is positioned, And a second blocking member for allowing only the second blocking member to be formed.

When the first induction coil part 210 and the second induction coil part 220 are disposed at positions spaced apart from each other by a predetermined distance in the vertical direction with respect to the adhesive layer 130, Thereby uniformly heating the adhesive layer 130, which is bended along the surface.

Generally, since the intensity of the induced current generated by the induction coil is inversely proportional to the distance, the distance between the adhesive layer and the induction coil affects the intensity of the induced current.

If the first induction coil 213 and the second induction coil 223 are installed in the upper and lower direction of the adhesive layer 130 as in the present invention, The sum of the first induction current generated by the first induction coil 213 and the second induction current generated by the second induction coil 223 provided under the adhesive layer 130 is greater than the sum of the second induction current generated by the adhesive layer 130).

This is because the interval between the first induction coil 213 and the second induction coil 223 is always constant on the basis of the adhesive layer 130. As a result, if the induction coil is installed in the vertical direction of the adhesive layer 130, the adhesive layer 130 is uniformly heated over the entire surface.

The transfer unit 400 transfers the first bonding object 110 and the second bonding object 120 to the induction heating space in a state in which the adhesive layer 130 is coated.

The transfer unit 400 includes a moving member that moves while passing through the induction heating space, and a driving unit for driving the moving member.

The first bonding object 110 and the second bonding object 120 move on the upper surface of the moving member in a laminated state via the adhesive layer 130.

The moving member is preferably made of a non-metallic material that is not affected by the magnetic field generated by the induction coil. This is because, if the moving member is made of a metal material, it will be unnecessarily heated by the induction heating apparatus.

The present invention is not limited to the above-described embodiments, and the transfer unit 400 may prevent the alignment of the bonding objects when the first bonding object 110 and the second bonding object 120 are conveyed, And an object holding member for holding the object. The object fixing member may be embodied in various forms.

For example, the object fixing member may be realized in the form of a plastic holder which is made of a non-metallic material, one end of which is fixed to the moving member and the other end of which is pressed against the upper surface of the second object 120 to be bonded.

In addition, the object fixing member may be fixed to the movable member in the form of an object receiving block in which an object accommodating portion capable of accommodating the object to be adhered is formed.

  The pressing unit presses the first bonding object 110 and the second bonding object 120 adhered by the adhesive layer 130.

The present invention is not limited to the above-described embodiments, and may be applied to the adhesive layer 130 (see FIG. 1) to check whether the temperature of the adhesive layer 130 is outside the allowable range when a magnetic field is formed on the induction heating space. And a sensor unit (not shown) for measuring the temperature of the fluid.

By measuring the temperature at a plurality of positions in the adhesive layer 130 using the sensor unit, it is possible to grasp a position out of the allowable range. The sensor unit may be a non-contact type infrared temperature sensor or the like.

Further, the present invention may further include a temperature adjusting unit for adjusting the temperature of the adhesive layer 130 when the temperature of the adhesive layer 130 measured by the sensor unit is out of the allowable range.

The temperature adjusting unit may include a heating unit capable of locally heating the adhesive layer region when the temperature of the adhesive layer 130 is lower than a permissible range and a heating unit capable of heating the adhesive layer region when the temperature of the adhesive layer 130 is higher than a permissible range And a cooling unit capable of locally cooling the region of the adhesive layer corresponding to the area of the adhesive layer.

Of course, the present invention is not limited to this, and the current application step may be performed first, and the transfer step may be performed.
