Description

Shoe press for shoe gluing with pressure plate {hydraulic press for shoe gluing}

The present invention relates to a shoe bonding press, and more particularly, when the shoe is accommodated to bond the upper and the sole of the shoe, by using a double pressure plate at the same time to transmit pressure evenly by the pressure plate to the adhesion portion of the shoe The present invention relates to a shoe-compression bonding machine equipped with a pressure plate for adhering shoes.

In general, in the case of a shoe is formed of the sole coupled to the upper and the upper.

The sole consists of an outsole that forms the sole of the shoe and a midsole that usually forms the sole of the shoe. The outsole is usually made of rubber material to satisfy the functions for wear resistance and anti-slip, and the midsole is mainly made of foamed and expanded synthetic resin material for absorbing the impact and restoring it when it is light and impacted. do.

Since the outsole and the midsole constituting the sole as described above is different in material and the manufacturing method is different, the outsole is usually manufactured separately so that the outsole is attached to the bottom of the midsole. When the sole of the shoe is manufactured, the upper is coupled to the sole, thereby manufacturing the shoe.

The sole manufacturing process, the upper manufacturing process and the bonding process of the sole and upper is usually made of a continuous working process. And, during the last step of the work, there is provided a step of pressing the entire upper portion of the bonded shoe so that the bonding can be performed well in the state that the sole and the upper are bonded.

In order to perform the pressing process for such bonding bonds, a compactor is usually used. Conventional compactors have a structure in which a plurality of pushing members are provided, and these pushing members push the shoes from all sides of the shoes, thereby promoting hardening of the adhesive bonded to the shoes.

The compactor is generally composed of a base frame on which a shoe is placed, a vertical pushing member installed on an upper portion of the base frame, and a plurality of horizontal pushing members installed on a side portion of the base frame.

By the way, in the conventional compactor, the pressing function is performed only at the pressing portion of the pushing member, so that the entire position of the shoe is not evenly pressed, and thus the bonding rate of the shoe is not high and the defective rate is increased. In addition, there is a disadvantage that the shoe is damaged by the pushing member.

In addition, since the base frame on which the shoes are placed is relatively expensive, there is a problem that the manufacturing cost increases. In addition, since the pushing member presses the shoe with a relatively strong force, the operator's hand is pressed by the pushing member, so that a safety accident is likely to occur.

In order to solve the above problems, various types of compactors have been introduced.

One of them is the shoe compactor introduced in the Korean Utility Model Application No. 1993-8144.

The prior art is shown in Figures 1-3. The support plate 3 is installed on the upper left and right support legs 2 installed on the body, and the air cylinder 4 is installed thereon, and the pressure plate 5 is installed at the bottom of the piston rod 4 ′ fitted thereto. 5) by installing the tank (6) to ground the upper rubber pad (7) in the opening of the tank (6) to form an air pocket (9) stretched in one direction by fixing with a pad cover (8), The lower rubber pad 7 ', which is in contact with the rubber pad 7, is grounded in the opening of the lower tank 6' installed on the body and fixed by the pad cover 8, thereby expanding and contracting in one direction. ′) Is formed. Therefore, by supplying compressed air through the fluid pipe (11) (11 ') connected to the upper and lower air bag (9) (9') is configured so that the rubber pad can compress the sole.

However, the above-described prior art has problems described below.

First, in the case of pressurization by pneumatic pressure, since the commercial pressure is usually 5-7 kg / cm ² , there is a problem that it is difficult to obtain high pressure without a separate expensive facility.

Second, when the rubber pad is torn during operation, such a phenomenon as when the air-inflated rubber balloon bursts momentarily is very likely to cause a safety accident.

Third, in the case of air, if the pressure is applied, the volume of the air itself is reduced and the pressure is not properly transmitted to the rubber pad.

Fourth, the pressure is strongly transmitted to the protrusions in the process of pressing by the rubber pad of the flat shape, when the pressure is transmitted to the adjacent protrusions of the shoe, the protrusions are first compressed and accordingly the sole and the predetermined portion between the rubber pad and the shoe. Since the upper is not bonded at the correct position and is bonded to each other, there is a problem in that poor adhesion is likely to occur.

Fifth, since the compressed air is supplied to the upper and lower air pockets and the rubber pad and the shoe are in contact with the rubber pad and the shoe, a predetermined air filled portion is formed between the rubber pad and the shoe. There is also the problem of not being able to.

Another conventional technology, which is filed by the applicant, is introduced in the Korean Utility Model Registration No. 20-188611, entitled Hydraulic Presser for Shoe Bonding Process.

The prior art, as shown in Figure 4, is installed on the base frame 50, the vertical upper cylinder 60 and the piston to move up and down, and fixed to the piston of the vertical upper cylinder 60 Shoes bonded together with the lower pressing plate 71 reciprocating up and down and receiving water therein to be contracted and expanded by water pressure, and the lower pressing plate 71 installed on the upper portion of the lower pressing plate 71 to rise. Pumping the water contained in the upper compression plate 72 and the water storage tank 80 and water storage tank 80 for supplying water to the upper and lower compression plates (71, 72) to press the water pressure It is configured to include a pump for supplying the upper and lower compression plates (71) 72, the water is supplied to the upper and lower compression plates (71) 72 is configured to compress the shoes through the rubber membrane.

However, the prior art has a problem that, firstly, the rubber film attached to the upper and lower compression plates is pushed by the hydraulic pressure and is separated from the upper and lower compression plates.

In addition, the rubber membrane is first adhered to the protruding portion during the process of the rubber membrane being closely adhered to the shoe by the high pressure of the water at a time. have.

In order to solve the above problems, the Korean Patent and Trademark Registration Utility Model Registration No. 20-226009 has been introduced for the pressure bonding presser for shoe adhesion provided with a pressure plate applied by myself.

The prior art has the advantage of compressing all parts of the shoe evenly by pressing the shoes in the upper and lower way, but when forming the shoe finished, the wrinkle is generated in the upper by the pressing force, the sole of the lower part of the upper There is a problem in that it is not suitable for the adhesion of the shoe-fiber that the pressure should be transmitted only to the adhesive portion of the sole and the upper by bonding.

In the case of the upper and lower pressure plate, the adhesive part is pressurized by hydraulic pressure. The thickness of the upper and lower pressure plate must be such that it can withstand the hydraulic pressure. When the thickness becomes thick, it is impossible to press against the recessed part of the uneven parts such as the sole. If it becomes thin, it is also possible to pressurize the depression, etc., but there is also a problem such that the pressure plate is not ruptured because the pressure cannot be overcome.

Therefore, the present invention was devised to solve the above problems, and provides a shoe press bonding press for attaching a shoe to press the adhesive portion of the upper and the sole of the shoe press and at the same time to transfer the equivalent pressure. For the purpose of

And, when pressing the adhesive part, by adopting the dual pressure method in which the pressure transmitted to the external pressure plate to the internal pressure plate by the internal pressure plate to press the adhesive portion, the occurrence of wrinkles by the upper phenomenon of the upper is prevented, It is also an object of the present invention to provide a shoe-compression bonding machine equipped with a pressure plate in which pressure is equally transmitted to the pressure plate.

It is also an object of the present invention to provide a shoe-compression bonding machine equipped with a pressure plate capable of pressurizing the inner pressure plate effectively while pressing the depression of the sole by the double compression method, even when the inner pressure plate is damaged by the impact of the shoe. .
