BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a compression bonding apparatus for bonding a floor window to a shoe, and more particularly, to a compression bonding apparatus for bonding a floor window to a shoe, And more particularly to a compression bonding apparatus for joining a floor of a shoe for providing a uniform pressing force.

Generally, shoes are made of natural or artificial leather, and are made up of an upper shell covering upper and lower sides of the foot, a bottom reaching the ground, and a bend attached to the heel of the bottom.

Each of these shoes is manufactured by preliminarily preparing a floor window, an upper and a heel which are constituent elements of a shoe, and then using a joining member such as a glue, a thread, or a nail. Therefore, if the manufacturing process of the shoe is complicated and the joining member which combines the components of the shoe is not robust, the shoe is easily lost. Especially, if the upper part, the middle part, the bottom part and the heel of the main constituent of the shoe are not properly joined, the function as the shoe can be lost.

Additional components such as glue, thread, and nails, as well as upper, mid and bottom windows prepared conventionally to make shoes are used. At this time, the floor window is joined after the middle is joined to the upper part, and a pressing frame and a presser corresponding to the size of the corresponding shoes are required to join the floor window. In order to bond the bottom window under the upper part of the middle joint, the bottom of the press frame was bonded to the lower part of the upper jointed with the middle, and then joined by using the presser. Therefore, each of the compression molds having the same shape and shape as the size of the corresponding shoes must be prepared. Therefore, the compression mold having a shape and shape suitable for the shoe must be manufactured by a separate mold, so that it is not only costly to manufacture the compression mold, but also needs to consider the problem of durability according to the use of the compression mold, There was also a problem of rising unit price.

A first aspect of the present invention relates to a compression bonding apparatus for bonding a floor window to a floor having a midsole joined thereto during a process of manufacturing a shoe, . Furthermore, in the present invention, the shoes using the compression bonding device for joining the bottom of the shoes do not distinguish between men and women, but in the present invention, women's shoes, particularly women's shoes with a certain length of heel, will be described.

1 and 2, the compression bonding apparatus 100 includes a fixing member 32, an inflation bag 20, a receiving member 10, and a pressing member 11.

The receiving member 10 has a curved surface inclined at a predetermined angle on one side of the top surface and an insertion groove 12 for receiving the heel 6 of the shoe while the other side is substantially flat. The supporting member 10 has a substantially "b" -shaped shape and the upper end surface has a shape similar to the bottom surface of the shoe 1. The supporting member 10 is made of a hard material such as wood or synthetic resin. The insertion groove 12 of the receiving member 10 is formed in a polygonal or circular shape to a predetermined depth from the upper end of the receiving member 10. The support member 10 may be made of wood, synthetic resin, or metal.

The pressing member 11 is fixed to the upper end surface of the supporting member 10 except for the insertion groove 12 with a predetermined thickness and is fixed to the bottom surface of the shoe 1 while supporting the shoe 1 to which the bottom window 4 is to be joined. It is to apply dispersed pressure. The compression member 11 is rubber or synthetic resin having elasticity, or fluidic liquid is embedded in a pack made of rubber or synthetic resin. Further, the compression member 11 may be made of a soft material such as a gel having fluidity in a semi-solid state. When the pressure is applied from the outside, the pressing member 11 acts as a side surface and an upper portion of the pressing member 11 against the pressing portion. This is because the limited volume of the compression member 11 is a reaction force against the pressure. The pressing member 11 is so formed that the shoe 1 is fixed on the pressing member 11 and the upper part of the shoe 1 is fixed to the fixing member 32 The pressing member 11 is pressed by the pressure and supports the lower surface of the bottom window 4 and the lower portion of the upper member 2 while pressing the pressing member 11 under a certain pressure. Furthermore, it is preferable that the surface of the pressing member 11 has a surface roughness such that the bottom window does not slip due to the pressure applied from above and below when the bottom window is joined to the shoe bottom surface to which the middle window is joined.

Further, the supporting member 10 and the pressing member 11 are preferably made to have a size capable of accommodating a commonly used shoe size.

The fixing member 32 is fixed to the upper end of the shoe 1 in which the shoe tongue 5 is inserted, that is, the upper front edge of the shoe 1 and the upper end of the shoe tongue 5, do. One or more fixing members 32 are fixedly coupled to a support bar 31 such as a clamp and the fixing member 32 is fixed to the upper or lower portion or the left or right side depending on the positions of the shovel 5 or the upper 2. [ And the interval is adjusted.

The expansion bag 20 on which the support member 10 is placed is fixed on the plate 30 and a device for moving the plate 30 up and down at a predetermined height may be provided under the plate 30. Air is injected into the inflating bag 20 through the hose 21 to inflate it, or the injected air is discharged to be reduced. An open / close valve (not shown) for injecting or discharging air may be mounted on the hose 21, and a compressor for injecting or discharging air through the hose 21 may be connected. Further, it is preferable that the inflation bag 20 is structured such that it is raised upward or downward due to air pressure injected or discharged.

Hereinafter, the operation of pressing and joining the bottom window to the bottom of the shoe in which the middle window is joined will be described using the compression apparatus for joining the bottom window of the present invention.

3 and 4, the upper 2 of the shoe has a predetermined shape ranging from the toes, the insteps, the side of the feet to the heel, and the upper 2 is formed by joining the upper 2 with threads or glue. And the midsole (3) is integrally joined to the lower portion of the upper (2), that is, the position corresponding to the sole. Therefore, the lower end portion of the upper portion is wrapped around the bottom edge of the midsole 3 located on the inner bottom surface of the upper portion 2. And the floor window 4 is coupled to the bottom of the shoe 1 to which the middle window 3 is coupled. The floor window (4) is joined to the bottom surface of the shoe (1) to which the midsole (3) is joined by glue or the like. Then, constant pressure is applied for a predetermined time to firmly bond the bottom window 4 to the bottom of the shoe 1. At this time, a compression bonding apparatus 100 is used for pressing the shoe 1 and the bottom window 4 for bonding.

The compression bonding apparatus 100 is provided with an expansion bag 20 on a plate 30 and positions the support member 10 having the compression member 11 integrally coupled to the expansion bag 20. Then, the shoes (1) to which the midsole (3) is joined are placed on the pressing member (11). At this time, the shoe heel 6 is inserted into the insertion groove 12. The fixing member 32 coupled to the support bar 31 of the compression bonding apparatus 100 is placed on the upper end of the upper end of the shoe 1 and the shoe bottom 5 respectively. Then, a certain pressure of air is injected through the hose (21) of the inflating bag (20). The inflated bag 20 is inflated upward by the injected air and pushes up the supporting member 10. [ When the supporting member 10 rises, pressure is transmitted to the shoe 1 to which the bottom window 4 fixed on the pressing member 11 is joined.

At this time, the pressing member 11 primarily presses the bottom surface of the bottom window 4 of the shoe 1 by the pressure, and the pressing member 11 is expanded around the pressed portion and is pushed up from the vicinity of the shoe 1 Is pressed against the bottom outer surface of the upper part (2) of the shoe (1) together with the bottom window (4) of the shoe (1). The amount of air injected into the inflating bag 20 and the pressing time may vary depending on the type, shape, or floor window of the shoe. After a certain amount of air is injected into the inflating bag 20, the opening / closing valve coupled to the hose 21 is closed to apply pressure to the shoe 1 for a predetermined period of time.

Then, when the pressing force and the pressing time set at the bottom of the shoe 1 have elapsed, the opening / closing valve coupled to the hose 21 is opened to discharge the air injected into the inflator 20. When the air is discharged from the inflating bag 20, the inflating bag 20 is lowered to descend the supporting member 10. When the pressure applied to the pressing member 11 integrally coupled to the supporting member 10 is released, the fixing member 32 provided on the supporting table 31 is moved from the upper 2 of the shoe 1 to the shoe bottom 5 The shoe 1 fixed between the pressing member 11 and the fixing member 32 can be separated.

Therefore, when the bottom window 4 is pressurized and joined to the bottom surface of the upper part 2 coupled with the middle window 3 at a constant pressure, the bottom edge of the upper part 2 and the middle window 3 and the bottom window 4 are integrally joined, It is not necessary to use a separate device for joining the window 4 or a compression mold suitable for a shoe size, so that it is possible to reduce the manufacturing time and cost of the shoe.

5, it may be necessary to join the bottom window 4 to the inside of the bend 6 while the bottom window 4 is coupled to the shoe bottom joined to the upper 2 and the middle 3. The pressing force is transmitted by the expansion of the pressing member 11 fixedly coupled to the insertion groove 12 and the pressing force is transmitted to the bottom of the bottom window 4 And a part thereof is joined inside the shoe sole 6.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone who has it will know it easily.
