Description

SHOEMAKING PRESS MACHINE TECHNICAL FIELD The present invention relates to a shoemaking press machine which facilitates and improves the good adhesion of a sole to a upper of a various kinds of shoes, - for example, leather shoes, soccer shoes, high heels, sports shoes, mountain shoes, - by the pressing force of piston rods of the shoemaking press machine.

BACKGROUND OF THE INVENTION The present invention is an improvement of an invention on the shoemaking press machine which is described in the applicant's utility model registration no. 76955 and no. 76956. According to the applicant's above-mentioned registered utility models, the press machine is described where several cylinders are installed in the table, and press boards are attached to the end of a piston rods, which press boards of a piston rods, by the action of cylinders, press the sole and upper of a shoe, the toe and heel of which being pressed and kept static by a toe bar and a heel bar, thereby accomplishes the adhesion of the sole and upper of a shoe by pressing force of the press boards.However, lots of inferior goods have been produced due to the following important reason; the table face on which the sole is set for processing is made of flat and hard material, which does not flexibly correspond to the bend of the sole. Thus, when the toe and the heel are pressed by the toe bar and the heel bar respectively, the pressure brought to bear on the bent sole of a shoe is not uniformly made and thereby good adhesion can hardly be accomplished. Therefore, specially with soles having extreme bend, e.g. sole of a high heel, the existing press machine for shoemaking can hardly achieve the end.

SUMMARY OF THE INVENTION In it's broadest aspect the present invention provides a shoemaking press machine capable of bringing out better adhesion results.

In particular, there is provided, a shoemaking press machine for adhering a sole and an upper of a shoe by a pressing force comprising a support for supporting a shoe, a casing having an opening and which is moveable with respect to the shoe support, a plurality of support boards held within the casing for pressing against a sole of a shoe and being moveable up and down corresponding to the bend of a sole of a shoe, a plurality of moving plates provided under said support boards which are moveable up and down corresponding to the bend of a sole of a shoe, a plurality of balls provided in the bottom of said casing which are moveable corresponding to the movement of said moving plates, wherein movement of the casing with respect to the support presses the support boards against the sole of the shoe, and the support boards move to provide an even pressure to the sole of the shoe.

An embodiment of the invention comprises a table for being moved up and down by a cylinder; an opening with a casing formed in the middle of the table; a protruded part formed symmetrically inside of said casing; a plurality of support boards provided under a sole of a shoe for being moved up and down corresponding to the bend of a sole of a shoe; a plurality of moving plates provided under said support board for being moved up and down corresponding to the bend of a sole of a shoe; a plurality of balls provided in the bottom of said casing for being moved corresponding to the movement of said moving plates; a plurality of guide sticks fixed to said protruded part of said casing engaging into a plurality of guide holes; and a plurality of springs provided at the circumferential surface of said guide sticks. an opening with a casing fixed with bolts formed in the middle of the table on which the sole of a shoe is set to be processed. A multitude of glass-bead-like balls, made of metal, plastic, glass or other suitable material, are put in the bottom of the casing, upon which a multitude of moving plates are installed.

Uppermost parts of the respective moving plates, support boards, made of urethane, rubber, sponge or other cushioned synthetic materials, are fixed. Respective moving plates are made movable due to the elastic force of respective springs installed within the guide holes of the casing.

As the support boards of respective moving plates move up and down complying with the bend of the sole of a shoe, each ball under the moving plates moves along the movement of the moving plates until final settlement corresponding to the bend of the sole is reached.

In this state of final settlement, pressing strength on the sole becomes uniform, resulting in good adhesion of the sole to the upper of a shoe.
