Description

롤러스탠드 감시장치{APPARATUS FOR MONITORING OF ROLLER STAND}Roller stand monitoring device {APPARATUS FOR MONITORING OF ROLLER STAND}

본 고안은 롤러스탠드 감시장치에 관한 것으로, 보다 상세하게는 롤러스탠드의 내부작업시 안전사고의 발생을 최소화하는 롤러스탠드 감시장치에 관한 것이다.The present invention relates to a roller stand monitoring device, and more particularly to a roller stand monitoring device to minimize the occurrence of safety accidents during the internal working of the roller stand.

일반적으로 롤러스탠드는 도 1에 도시된 바와 같이, 상부작업롤(10a) 및 하부작업롤(10b)을 포함하는 작업롤(10), 상부백업롤(20a) 및 하부백업롤(20b)을 포함하는 백업롤(20), 하우징(30)을 포함한다. 작업롤(10)은 제품(40)과 직접 접촉하여 제품(40)을 압연한다. 백업롤(20)은 작업롤(10)과 접촉하여 회전하면서 제품(40)의 압연에 필요한 압하력을 작업롤(10)에 가한다. 하우징(30)은 작업롤(10) 및 백업롤(20)을 지지한다. 이러한 롤러스탠드(60)에서는 롤러스탠드(60)의 내부를 점검 또는 청소하기 위해 작업롤(10)을 하우징(30)에서 분리한다. 작업롤(10)의 분리가 완료되면, 작업자는 롤러스탠드(60)의 내부에 물을 뿌려 이물질을 제거하거나 점검을 한다. 운전자는 롤러스탠드(60)의 재가동을 위해 롤러스탠드(60)의 내부에 작업자 또는 점검설비의 존재를 육안으로 점검한다.Generally, the roller stand includes a work roll 10 including an upper work roll 10a and a lower work roll 10b, an upper backup roll 20a, and a lower backup roll 20b, as shown in FIG. To include a backup roll 20, the housing 30. The work roll 10 is in direct contact with the product 40 to roll the product 40. The backup roll 20 applies the pressing force necessary for rolling the product 40 to the work roll 10 while rotating in contact with the work roll 10. The housing 30 supports the work roll 10 and the backup roll 20. In the roller stand 60, the work roll 10 is separated from the housing 30 to check or clean the inside of the roller stand 60. When the separation of the work roll 10 is completed, the worker sprays water inside the roller stand 60 to remove foreign substances or check. The driver visually checks the presence of an operator or inspection facility in the roller stand 60 to restart the roller stand 60.

이러한 종래의 롤러스탠드에서는 운전자가 롤러스탠드의 내부를 육안으로 확인한 후에 작업자가 내부로 진입하여 작업을 하는 경우가 발생한다. 그리하면, 운 전자가 내부의 작업자를 확인하지 못한 상태에서 작업롤을 롤러스탠드로 삽입하여 대형 안전사고가 발생하는 문제점이 있다.In such a conventional roller stand, the operator visually checks the inside of the roller stand, and then the operator enters the inside and works. Then, there is a problem that a large safety accident occurs by inserting the work roll into the roller stand in the state that the operator does not identify the operator inside.

또한, 운전자가 롤러스탠드의 내부에 점검설비(또는 청소도구)를 확인하지 못한 상태에서 작업롤을 롤러스탠드로 삽입하여 롤러의 제품수명이 단축되는 문제점이 있다.In addition, there is a problem that the product life of the roller is shortened by inserting the work roll into the roller stand in a state where the driver does not check the inspection facility (or cleaning tool) inside the roller stand.

본 고안은 상기한 종래의 문제점을 감안하여 제안된 것으로서, 그 목적은 롤러스탠드의 내부의 작업자 및 점검장비의 유무를 알려주도록 한 롤러스탠드 감시장치를 제공함에 있다.The present invention has been proposed in view of the above-mentioned conventional problems, and an object thereof is to provide a roller stand monitoring device for informing the presence or absence of a worker and an inspection device inside the roller stand.

상기한 목적을 달성하기 위하여 본 고안에 따른 롤러스탠드 감시장치는, 압연공정의 롤러스탠드를 감시하는 장치로서, 롤러스탠드의 내부에 위치한 작업자 또는 점검장비를 감지하는 감지부; 감지부로부터 감지신호를 수신하면 알람신호를 발생하는 제어부; 및 제어부로부터의 알람신호를 근거로 롤러스탠드의 내부에 작업자 또는 점검장비가 존재함을 알려주는 알람부를 포함한다.Roller stand monitoring device according to the present invention to achieve the above object, a device for monitoring the roller stand of the rolling process, the sensing unit for detecting the operator or inspection equipment located inside the roller stand; A control unit for generating an alarm signal when receiving a detection signal from the detection unit; And an alarm unit for notifying the presence of an operator or inspection equipment in the roller stand based on the alarm signal from the controller.

감지부는 발신부와 수신부가 롤러스탠드의 외부에 상하 대각선방향으로 설치되는 다수개의 포토셀로 구성된다.The sensing unit includes a plurality of photocells in which the transmitting unit and the receiving unit are installed up and down diagonally outside the roller stand.

다수의 포토셀이 롤러스탠드의 내부를 교차하여 감지한다.Multiple photocells sense across the interior of the roller stand.

본 고안에 의하면, 포토셀을 이용하여 롤러스탠드의 내부의 작업자 또는 점검장비를 감지하여 알려줌으로써, 작업자의 안전사고를 방지하고 롤러의 제품수명단축의 최소화할 수 있다.According to the present invention, by detecting and notifying the worker or inspection equipment inside the roller stand by using a photocell, it is possible to prevent the safety accident of the operator and to minimize the product life of the roller.
