The glue line is thus drawn on the uppers 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention relates to a shoe manufacturing process,
The present invention relates to a glue wire drawing device that automatically performs a glue wire drawing operation for applying glue for bonding an upper shell, a shoe sole, tape and the like to a lower peripheral edge of the upper shell.

[0002]

2. Description of the Related Art In a shoe making process, when the upper cover (1) and the shoe sole (3) are adhered to the lower peripheral edge (2) of the upper cover (1) with a tape as shown in FIG. Conventionally, the operator has manually drawn the glue wire (4) for applying the glue (4) to the instep cover (1) covered with the shoe mold (5).

[0003]

The above-mentioned glue wire drawing work is
In order to prevent the glue (4) applied to the instep cover (1) from excessively protruding when the tape is adhered, it must be applied in a substantially straight line along the lower peripheral edge of the instep cover (1). However, the lower rim of the instep (1) is not in a straight line,
Curved so that it rises from the middle part to the tip,
It was very difficult to draw a glue line along the curved curve and required skill. Therefore, the work efficiency was poor and the productivity was low.

Therefore, it is required to mechanize the glue line drawing work, but since the shoes for the right foot and the one for the left foot have different shapes, and there are shoes of various sizes, there is a device that can handle them. Development was difficult and it was not mechanized yet.

The present invention seeks to provide a glue wire drawing device for automatically applying glue to both side surfaces of the upper cover of every shoe.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a mold mounting base on which a shoe mold with an instep cover is mounted, and the mold mounting base is disposed above the mold mounting base so as to oppose the shoe mold to the mold mounting base. Fixing means for fixing the same, a coating nozzle for ejecting glue, and a guide roller for directing the coating nozzle to the instep of the shoe mold, and a pair of coating means arranged on both sides of the mold mounting table, A pair of pressing means for moving the coating means in the width direction and pressing it against the instep cover, a pair of feeding means for moving the coating means and the pressing means in the front-rear direction, and a feeding means installed below the coating means. The application means is moved up and down in accordance with the gradient of the lower side surface of the shoe mold in accordance with the feeding operation of, and the application means is configured to follow the side surface of the instep cover attached to the shoe mold. is there.

Further, the coating means is provided with a pair of guide rollers rotatably mounted on a base which is swingably supported, and a coating nozzle is movable forward and backward so as to project from a space between the pair of guide rollers toward the die mounting table side. It has a structure provided in.

Further, the copying means has an inside copy plate and an outside copy plate formed so as to copy the side surface of the largest shoe mold, and the inside copy plate and the outside copy plate are the size of the shoe mold. The front-rear direction alignment is performed according to this.

Further, the copying means has a pair of support blocks in the width direction, one of the support blocks is provided with a copy plate for the inside of the right foot and the copy plate for the outside of the left foot, and the other support block is provided for the outside of the right foot. Providing a copy plate and a copy plate for the inside of the left foot, and arranging so that the copy plates for the inside of the right and left feet come inside, and moving the pair of support blocks in the width direction, shoes for the right foot or the left foot. The copying plates may be switched and used according to the mold.

[0010]

In the glue wire drawing apparatus, the shoe mold with the instep cover is placed on the mold mounting table, the heel side of the shoe mold is positioned, and the shoe mold is fixed by pressing the fixing means from above. After fixing, the application means is moved to the shoe mold side by the pressing means, the application nozzles of each application means are brought into contact with the starting ends of the glue lines near the heels on both lower sides of the instep, and then the application means by the feeding means. Is moved forward, and the copying means moves the coating means so as to follow the shape of the lower peripheral edge of the instep to perform the glue line drawing work.

Further, if the coating nozzle and the guide roller of the coating means of the glue wire drawing device can be swung, the coating nozzle can always be applied almost vertically to the instep, and the glue can be stably coated. can do.

Further, even if the size of the shoe shape changes, the shape of the curved portion hardly changes and only the length of the horizontal portion changes. Therefore, if the position of the copying plate of the copying means in the front-back direction is shifted. The rising start point of the application nozzle can be changed according to the shoe shape, and the application nozzle can accurately follow the curved portion of the instep.

Further, if the copying means has a copying plate for the right foot and a copying plate for the left foot, the copying plates can be switched to easily glue to the shoe pattern of either the right foot or the left foot. You can draw a line.
