Description

프레스의 선행작동 안전장치{Preceding actuation safety device of presses}{Preceding actuation safety device of presses}

본 발명은 프레스의 선행작동 안전장치에 관한 것으로서 보다 구체적으로는 상부금형의 하강시에 상부금형보다 선행하여 안전장치가 하강함으로서 프레스와 작업자 사이에 격벽을 형성할 수 있도록 하여 소재의 투입 및 제품의 취출시에 작업자의 손이 프레스금형의 내부에 투입되어 발생하는 안전사고를 미연에 방지할 수 있도록 하는 프레스의 선행작동 안전장치를 제안한 것이다.
More particularly, the safety device is lowered prior to the upper mold when the upper mold is lowered, so that a partition wall can be formed between the press and the worker, The present invention relates to a pre-operation safety device for a press, which can prevent a safety accident that occurs when the operator's hand is inserted into the press mold during the release of the presser.

일반적으로 프레스는 상부금형과 하부금형을 장착하여, 이들 하부금형과 상부금형 사이에 철판소재를 넣고 프레싱 하여 그 소재를 드로잉 및 밴딩 또는 블랭킹 및 펀칭 등 철판을 가공하여 제품을 제조하는 산업기계이다.Generally, the press is an industrial machine for manufacturing a product by mounting an upper mold and a lower mold, pressing an iron plate material between the lower mold and the upper mold, and processing the material by drawing, bending, blanking and punching.

상기와 같은 프레스는 상부금형과 하부금형의 사이로 소재의 투입 및 제품의 취출시에 상,하부금형의 사이로 작업자의 손이나 신체 일부가 투입된 상태에서 작동하게 되어 안전사고가 빈번이 발생하는 문제가 있었다.      The above-mentioned press has a problem that frequent safety accidents occur because the work is put into the space between the upper mold and the lower mold and the worker's hand or body part is inserted between the upper and lower molds during the introduction of the material and the release of the product .

즉 프레스작업은 단순반복 작업이기 때문에 처음 작업 시에는 긴장하여 작업한다 하더라도 작업이 반복되는 과정에서 자신도 모르게 긴장이 풀리게 되며, 이에 따라 부주의가 발생하게 되어 사고가 발생되는 빈도가 다른 산업기계의 작업에 비하여 높게 된다.       In other words, since the press work is a simple repetitive work, even if the work is tense at the first work, the tension is released without knowing itself in the course of the work repeatedly. Accordingly, carelessness occurs, ≪ / RTI >

따라서 근래에는 상기와 같은 프레스작업의 산업재해를 예방하기 위하여 다양한 프레스작업의 안전장치가 제안되어 사용되고 있으며 안전장치로서 실용신안등록 제0383906호에서와 같이 투광기와 수광기를 이용하여 신체의 일부가 금형 내측으로 투입되어 투광기에서 조사하는 광선이 신체 등에 가려 수광부에 도달하지 못하면 프레스의 작동을 정지시키는 전기 및 전자적 안전장치와 등록특허 제0885859호에서와 같이 로드 선단에 안전밀판을 장착한 공압실린더와, 페달과 함께 연동하면서 상기 공압실린더를 제어하는 2개의 센서로 이루어지도록 구성하여, 프레스의 베드 소정위치에 장치하여 각종 제품을 성형할 때 프레스를 작동하는 페달에 압력이 전해지는 순간 상부금형이 하강하기 직전에 먼저 공압실린더가 작동하여 순간적으로 안전밀판을 전진시켜 소재 또는 반제품을 공급시키던 작업자의 손이나 신체를 외부로 밀어내어 사고를 예방할 수 있게 하는 기계 기구적 안전장치가 제안되어 사용되고 있으나 Therefore, in recent years, in order to prevent industrial disaster of the press work as described above, various safeties for press work have been proposed and used. As a safety device, as disclosed in the Utility Model Registration No. 0383906, a part of the body is molded using a light emitter and a light receiver An electric and electronic safety device for stopping the operation of the press when the light irradiated from the light emitter is irradiated to the inside of the body and the light beam can not reach the light receiving part and a pneumatic cylinder equipped with a safety plate at the rod end as in the registered patent No. 0885859, And a control unit for controlling the pneumatic cylinder so as to control the pneumatic cylinder while interlocking with the pedal, so that when the various devices are formed by placing the pneumatic cylinder at a predetermined position of the press pad, the moment the pressure is transmitted to the pedal, Just before the pneumatic cylinder is activated, To repel the hands or body of the worker sikideon supply materials or semi-finished products to the outside, but the machine is being used has been proposed mechanical safety device that allows users to prevent accidents

전자의 전기 전자적 안전장치는 센서 및 전기기구의 오류 및 오작동 등으로 인하여 신뢰성이 떨어지고 상부금형을 장착한 슬라이드의 하강을 강제 제어하도록 구성함으로서 설치비용이 매우 고가로 들게 되고 유지보수가 어려운 문제점이 있었고Electronic electronic safety devices are not reliable due to errors and malfunctions of sensors and electric appliances, and are configured to forcibly control the descent of the slide equipped with the upper mold, so that the installation cost becomes very expensive and maintenance is difficult

후자의 기계 기구적 안전장치 또한 작동하는 프레스에 작업자의 접근 신호 인지 시 자동으로 작동하여 금형 사이에 위치하는 작업자의 손이나 기구를 외부로 밀어내는 구조이므로 센서와 같은 전기적 장치가 개입되어 센서의 오작동과 같은 전기적 오류가 발생하여 근본적인 안전사고를 방지할 수 없는 제한된 기계기구적 구성으로 ,그 신뢰성이 떨어지는 등의 문제점이 있었다.
The latter mechanical mechanism safety device also operates automatically when an operator's access signal is received on the operating press to push the operator's hand or equipment located between the molds to the outside, so that an electrical device such as a sensor intervenes, There has been a problem that reliability is deteriorated due to a limited mechanical mechanism configuration that can not prevent a fundamental safety accident due to the occurrence of an electrical error such as a malfunction.
