Abstract

PURPOSE: A press rotary system is provided to have product competitiveness by achieving very high productivity and stability of quality with a minimum number of operators. CONSTITUTION: A press rotary system comprises a caterpillar rotating means, multiple molds mounted on the caterpillar rotating means, and multiple presses arranged along the caterpillar rotating means. The caterpillar rotating means is provided as a conveyor or a turn-table form. The multiple molds are arranged at an upper side of the caterpillar rotating means along a longitudinal direction. Seven presses for handling the molds are arranged at one side of the caterpillar rotating means. The molds are opened, and de-molding and mold-cleaning are conducted if the molds are located on a first position by a rotation with the caterpillar rotating means.

Description

Press rotary system {PRESS ROTARY SYSTEM}

The present invention is a technology for producing an outsole using a press so that a plurality of molds are moved by an endless track rotation means and when each mold arrives at a specific position, a predetermined set operation is automatically performed to enable continuous and efficient outsole production. To a press rotary system.

Outsole, one of the parts that make up the shoes, is usually molded using rubber, and the rubber dough is usually put in the mold, and then pressurized by heating with a press to obtain the outsole in the shape of the mold.

Each single element of the shoe has its own function, and since the outsole is always in contact with the ground, it must be non-slip and wear-resistant.

However, because outsoles have very little added functionality, they have similar shapes and shapes, so you need to be more productive to be competitive. The output of outsoles per unit time is more important than any other factor at the time of high wages.

Let's take a look at the current outsole manufacturing process.

Conventional outsole manufacturing allows four workers to operate four presses. Each press was operated while the four presses were fixedly installed at fixed intervals. That is, the outsole is manufactured by taking out the produced outsole by opening the mold, cleaning the mold, applying a release agent to the mold, adding rubber dough, closing the mold again, and pressing and heating.

Therefore, the quality and productivity were very different due to different proficiency for each worker, and the production efficiency is very low because the press and heating time should be rested without the worker's work.

In addition, the workers had to deal with heavy molds, resulting in high work fatigue and a high risk of safety accidents.

As a related art of the present invention, there is a "Rotary type shoe adhesion drying device" of Republic of Korea Patent Publication No. 10-2007-0080252 (published Aug. 09, 2007).

1 shows a plan view of the prior art, in which four chambers are arranged at an angle of 90 degrees, and each chamber is configured to be fixed and rotated on a chamber rotating shaft 2 installed vertically.

Therefore, the operator arranged in each chamber is a technology that allows to repeatedly perform a predetermined task assigned to them. This technique can be suitable for tasks that require a lot of manual work and for attaching uppers and soles that are made up of many processes.

However, high productivity is required and cannot be applied to the production of outsoles that are pressed into molds using presses.

1. Republic of Korea Patent Publication No. 10-2007-0080252 (published Aug. 9, 2007)

The present invention has been made in order to solve the problems of the prior art as described above, by rotating a plurality of molds by the endless orbital rotation means to achieve a very high productivity and quality stability even with a minimum of workers to ensure product competitiveness However, when each mold arrives at a specific position to provide a press rotary system for the press to automatically perform a specific operation for each mold.

In order to achieve the above object, the present invention, a crawler rotating means of the conveyor or turntable type; A plurality of molds mounted on the crawler means; It includes a plurality of presses arranged along the caterpillar rotation means, when each mold arrives at a specific position, it is characterized in that the opening and closing of the mold and heating for each press individually.

As described above, the present invention allows the plurality of molds to be rotated by the caterpillar rotating means so as to achieve a very high productivity and stability of quality even with a minimum of workers, so that each mold arrives at a specific position. A press rotary system is provided to allow a press to automatically perform a specific operation.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention in the drawings, portions not related to the description are omitted, and like reference numerals are given to similar portions throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise.

1 is a plan view showing an operating state of the present system, FIG. 2 is a front conceptual view of FIG. 1, and FIG. 3 is a side conceptual view of FIG. 2.

Caterpillar rotation means is provided in the form of a conveyor or turntable.

A plurality of molds are disposed along the longitudinal direction of the crawler rotating means on the upper surface of the crawler rotating means.

Seven presses for manipulating the molds are arranged on one side of the crawler rotating means.

When the mold is rotated to the first position by the caterpillar rotation means, the mold is opened and demolding and mold cleaning are performed.

When the mold is rotated by the caterpillar rotating means to come to the second position (the position after the first position), the primary dough is introduced into the mold and the mold is closed.

When the mold is rotated by the caterpillar rotating means to come to the third position (the position after the second position), the mold is pressed and air bleeding is performed.

When the mold is rotated by the caterpillar rotating means to come to the fourth position (the position after the third position), the mold is opened and cleaning is performed.

When the mold is rotated by the caterpillar rotation means and comes to the fifth position (the position after the fourth position) and the sixth position (the position after the fifth position), the secondary dough is introduced.

When the mold is rotated by the caterpillar rotation means and comes to the seventh position (the position after the sixth position), the secondary dough or the mold is closed.

The mold is rotated by the caterpillar rotating means so that the molds are pressed by presses from the position after the seventh position.

The mold is rotated by the caterpillar rotating means to maintain the clamp state by the pneumatic mechanism from the next position of the press.

The foregoing description of the present invention is intended for illustration, and it will be understood by those skilled in the art that the present invention may be easily modified in other specific forms without changing the technical spirit or essential features of the present invention. will be. It is therefore to be understood that the embodiments described above are intended to be illustrative, but not limiting, in all respects. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.

The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
