1 : 솔레노이드밸브 2 : 안전솔레노이드밸브1: solenoid valve 2: safety solenoid valve
본 고안은 PLC(Programmable Logic Controller)를 사용하여 솔레노이드 밸브로서 기계장치의 동작을 위한 유압 또는 공압 기기를 작동하는 과정에서 정전이나 기타 이상 발생에 의한 제품불량 발생의 원인 및 안전사고 요인을 미연에 제거할 수 있도록한 유, 공압기기의 안전장치에 관한 것이다.The present invention eliminates the causes of product defects and safety accidents caused by power failures or other abnormalities during the operation of hydraulic or pneumatic devices for the operation of mechanical devices as solenoid valves using programmable logic controllers (PLCs). It relates to safety devices for oil and pneumatic equipment.
일반적으로, 유. 공압을 이용한 기계장치들을 자동으로 작동시켜 주기 위하여, 근래에는 PLC를 사용하여 정해진 프로그램의 조작순서에 따라 유, 공압기기들, 예를 들면 기계장치의 이동을 실시하는 실린더의 작동을 이와 연결되어 있는 솔레노이드밸브 조가에 의하여 이를 제어하도록 하고 있다.In general, u. In order to automatically operate pneumatic machinery, recently, PLC is used to connect oil and pneumatic equipment, for example, cylinders for moving machinery, in accordance with a predetermined program operation sequence. This is controlled by the solenoid valve clamp.
그러나 제3도의 구성도와 같이, 실린더(3)와 같은 유, 공압기기에 솔레노이드밸브(1)를 단순하게 부착하여 도시가 생략된 PLC를 통해 실린더(3)의 작동을 제어하도록 된 종래 장치는, 기기의 작동중에 갑자기 정전이 발생하거나 실린더의 전진 과정중 갑작스런 복귀운동에 의하여 발생되는 사고 또는, 기계 정비시에 기기를 전진시켜놓은 상태로 복귀하게 되는 경우, 이들 사고를 방지하기 위한 별도의 안전장치가 구비되어 있지 못하여 제품 불량, 기계 파손, 안전사고에 의한 인명피해를 가져오게 되는 사례가 자주 발생하였다.However, as shown in the configuration of FIG. 3, the conventional apparatus in which the solenoid valve 1 is simply attached to an oil and pneumatic device such as the cylinder 3 to control the operation of the cylinder 3 through a PLC (not shown), Additional safety devices to prevent these accidents in case of sudden power failure during operation of the machine or an accident caused by sudden return movement during the cylinder's advancement, or when the machine is returned to the advanced position during machine maintenance. There is a case that often does not have a product caused by the failure of the product, mechanical damage, safety accidents resulting in casualties.
본 고안은 이와 같은 종래의 문제점에 착안하여 안출한 것으로, 유, 공압기기의 제어를 실시하는 솔레노이드밸브를 여러가지의 예기치 못한 사고에 대응하는 추가의 안전장치로서 이를 제어할 수 있도록 함을 목적으로 한다.The present invention has been devised in view of such a conventional problem, and aims to control the solenoid valve for controlling oil and pneumatic equipment as an additional safety device in response to various unexpected accidents. .
상기와 같은 목적을 달성하기 위한 본 고안의 형태에 따르면, 다수의 유, 공압기기를 각각 제어하는 솔레노이드밸브(1)들과 연이어 통하는 안전솔레노이드밸브(2)를 추가 설치하여서 된 것이다.According to a form of the present invention for achieving the above object, it is to install a safety solenoid valve (2) in communication with the solenoid valve (1) for respectively controlling a plurality of oil, pneumatic equipment.
이와 같이 된 고안을 첨부도면과 함께 설명하면, 제1도와 같이 2개의 실린더(3)가 병렬로 배치되고 이들 실린더(3)의 조작을 위한 솔레노이드밸브(1)가 실린더(3)와 연결 설치되어진 경우, 이들 솔레노이드밸브(1)가 실린더(3)와 연결 설치되어진 경우, 이들 솔레노이드밸브(1)가 실린더(3)와 연결 설치되어진 경우, 이들 솔레노이드밸브(1)와 통하는 하나의 안전솔레노이드밸브(2)를 각각 솔레노이드밸브(1)와 연결시켜 이들을 제어하도록 한 것으로서, 장치의 정상적인 작동시에는 안전솔레노이드밸브(2)가 온상태로서 각각의 솔레노이드밸브(1)와 함께 이에 연결되어진 실린더(3)가 정해진 정상적인 작동상태에서 작업이 이루어지고, 이와 반대로 정전시나 돌발적인 사고 발생시에는 안전솔레노이드밸브(1)의 동작을 차단시키게 된다.Referring to the present invention with the accompanying drawings, as shown in FIG. 1, two cylinders 3 are arranged in parallel, and a solenoid valve 1 for operation of these cylinders 3 is connected to the cylinder 3 and installed. In this case, when these solenoid valves 1 are installed in connection with the cylinder 3, when these solenoid valves 1 are installed in connection with the cylinder 3, one safety solenoid valve communicating with these solenoid valves 1 2) is connected to the solenoid valve (1), respectively, to control them, and in the normal operation of the device, the safety solenoid valve (2) is on, with each solenoid valve (1) connected to the cylinder (3) The operation is made in the normal operation state is determined, on the contrary, the operation of the safety solenoid valve (1) in the event of a power failure or an accident occurs.
제2도는 본 고안에 따른 안전솔레노이드밸브(2)을 사용하여 유, 고압 회로에 적용한 하나의 일실시예로서, 제어가 필요한 중요한 우측의 2개 실린더(3)를 안전솔레노이드밸브(2)로서 제어하도록 연결한 것으로, 현재의 상태는 안전솔레노이드밸브(2)가 오프되어 있는 상태으로 이경우에는 안전솔레노이드밸브(2)와 통하는 2개의 솔레노이드밸브(1)가 작동을 실시하지 않는 상태이다.2 is an embodiment applied to the oil and high pressure circuit using the safety solenoid valve (2) according to the present invention, the control of two important cylinders (3) on the right side that need to control as a safety solenoid valve (2) The current state is that the safety solenoid valve 2 is off. In this case, the two solenoid valves 1 communicating with the safety solenoid valve 2 are not operated.
이와 같은 상태에서 안전솔레노이드밸브(2)를 절환시켜주게 되면, 안전솔레노이드밸브(2)가 온되면서 솔레노이드밸브(1)가 실린더(3)의 작동을 실시하게 된다.When the safety solenoid valve 2 is switched in such a state, the safety solenoid valve 2 is turned on and the solenoid valve 1 operates the cylinder 3.
이와 같이 본 고안에 따른 안전솔레노이드밸브 장치는 유, 공압을 이용한 모든 장치에 적용 가능하게 위험 또는 제품의 손상을 줄 수 있는 요소에 장작시켜 줌에 따라 안전성과 함께 성능을 더욱 향상시킬 수 있게 되는 효과를 갖는다.As described above, the safety solenoid valve device according to the present invention can be applied to all devices using oil and pneumatics, and thus the safety solenoid valve device can be installed at an element that may cause danger or damage to the product.
