본 발명은 공작기계에 설치되어 안전사고로부터 작업자를 보호하는데 필요한 AUTO APC DOOR(자동팰릿교환장치의 자동문, 이하 '자동문'이라 함)에 관한 것으로, 특히 공작기계의 장비의 오동작 및 작업자의 임의조작으로 인한 안전사고를 미연에 방지할 수 있는 안전 스위치 장치에 관한 것이다.The present invention relates to an AUTO APC DOOR (hereinafter referred to as an automatic door of an automatic pallet changer, which is installed on a machine tool to protect an operator from safety accidents), in particular a malfunction of the machine tool and an arbitrary operation of the operator. The present invention relates to a safety switch device that can prevent safety accidents caused by accident.

일반적으로 자동 팰릿 교환형 수치제어 공작기계의 외부에는 작업자의 안전사고를 방지하기 위한 주된 목적으로 커버를 설치하였다. 그러나, 공작물의 착탈 또는 필요한 점검이나 고장의 수리 및 팰릿(pallet)의 교환작업이 가능하도록 하기 위해 자동문을 필수적으로 갖추게 되었으며, 이러한 자동문은 필요에 따라 적절한 구동수단에 의해 자동으로 개폐된다.In general, a cover is installed on the outside of an automatic pallet changeable numerical control machine tool for the purpose of preventing a worker's safety accident. However, automatic doors are indispensable to enable removal of the work piece, necessary inspection or repair of failures, and replacement of pallets. These automatic doors are automatically opened and closed by appropriate driving means as necessary.

상기 자동문의 한 예로 도 1에 나타낸 바와 같이 자동문을 여닫을 경우 이를 확인하기 위한 스위치가 각각 구비되어 있다.As an example of the automatic door, as shown in FIG. 1, when the automatic door is opened and closed, a switch for checking this is provided.

좀더 상세히 살펴보면 링크부(2) 상에 자동문이 조립되어있으며 자동문(1)이 닫혀 있는 경우에는 닫힘 확인용 리미트 스위치(4)가 온(ON)되고 자동문이 열려 있는 경우엔 열림 확인용 리미트 스위치(3)가 온(ON)된다.In more detail, when the automatic door is assembled on the link unit 2 and the automatic door 1 is closed, the closing check limit switch 4 is turned on and the automatic door is open when the automatic door is open. 3) is turned ON.

이러한 구성은 작업자가 임의로 스위치를 조작하기 쉬운 곳에 위치되어 있고 조작하기도 수월하여 실제로 융통성 있게 작업한다는 이유로 작업자가 임의로 조작 (테이프를 붙여 항상 ON되게 하든지 또는 안전 스위치인 경우 키(KEY)를 만들어 억지끼움)하여 실질적으로 문은 열린 상태이나 공작기계의 내부 프로그램은 닫힌 상태로 인식하게 하여 작업함으로써 안전사고의 위험이 항상 잠재되어 있고, 공작기계의 일부 부품의 고장으로 인해 자동문은 열려 있으나 닫힌상태로 인식이 되어 작업되어지는 경우 또한 종종 발생하였다.This configuration is located at the place where the operator can easily operate the switch, it is easy to operate, and it is easy to operate so that the operator can operate it arbitrarily. As a result, the door is actually opened or the internal program of the machine tool is recognized as a closed state, so there is always a risk of a safety accident, and the automatic door is opened but closed due to the failure of some parts of the machine tool. This often happened.

즉, 자동문이 열려있는 상태로 공작기계가 동작을 하면 공작물이 가공지역내로 이동될 때 도어의 개방지역을 통과할수 없게 되고 때로는 공작물이 자동문이나 기계장치의 외면에 충돌하여 기계에 심한 손상을 가져다주게 된다.In other words, if the machine tool is operated with the automatic door open, the workpiece cannot move through the open area of the door when the workpiece is moved into the machining zone, and sometimes the workpiece collides with the automatic door or the outer surface of the machine, causing severe damage to the machine. do.
