이하, 실시예를 통하여 본 발명을 더욱 상세히 설명하기로 한다. 이들 실시예는 단지 본 발명을 예시하기 위한 것이며, 본 발명의 권리 보호 범위가 이들 실시예에 의해 제한되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples. These embodiments are only for illustrating the present invention, and the scope of rights of the present invention is not limited by these embodiments.

이 과정에서 도면에 도시된 선들의 두께나 구성요소의 크기 등은 설명의 명료성과 편의상 과장되게 도시되어 있을 수 있다. 또한, 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로서 이는 사용자, 운용자의 의도 또는 관례에 따라 달라질 수 있다. 그러므로, 이러한 용어들에 대한 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 할 것이다.In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

도 1은 본 실시예에 의한 연주설비에서의 토치커팅머신 감시 장치의 블럭도이고, 도 2는 본 실시예에 의한 토치커팅머신의 구성도이며, 도 3은 본 실시예에 의한 연주설비에서의 토치커팅머신 감시 방법을 설명하기 위한 순서도이다.1 is a block diagram of a torch cutting machine monitoring apparatus in a playing facility according to the present embodiment, FIG. 2 is a block diagram of a torch cutting machine according to the present embodiment, and FIG. This is a flowchart for explaining a torch cutting machine monitoring method.

도 1 내지 도 3을 참고하면, 본 실시예에 의한 연주설비에서의 토치커팅머신 감시 장치는, 클램프 감지부(1a), 슬라브 에지 검출부(1b), 제어부(2), 클램프 구동부(3), 슬라브 절단부(4), 및 경보발생부(5)를 포함한다.1 to 3, the torch cutting machine monitoring apparatus in the performance equipment according to the present embodiment, the clamp detection unit 1a, the slab edge detection unit 1b, the control unit 2, the clamp drive unit 3, Slab cutout 4, and alarm generation 5;

클램프 감지부(1a)는 슬라브 절단시 클램프(6)가 슬라브 표면에 안착되었는지 여부를 감지한다. 여기서 클램프(6)는 슬라브 절단 시작시 슬라브 표면에 안착되어 토치커팅머신(7)을 슬라브와 동일한 속도로 이동시킨다. 그리고 슬라브 절단이 완료되면 클램프(6)는 리프팅(liftting)되고 토치커팅머신(7)은 레일(9)을 따라 이동한다.The clamp detector 1a detects whether the clamp 6 is seated on the slab surface when the slab is cut. The clamp 6 is here seated on the slab surface at the start of slab cutting to move the torch cutting machine 7 at the same speed as the slab. When the slab cutting is completed, the clamp 6 is lifted and the torch cutting machine 7 moves along the rail 9.

슬라브 에지 검출부(1b)는 슬라브 절단시 슬라브 에지를 검출하여 제어부(2)로 전송한다.The slab edge detector 1b detects the slab edge and cuts the slab edge and transmits the slab edge to the controller 2.

제어부(2)는 슬라브 절단명령이 입력되면 클램프(6)가 슬라브 표면에 안착되도록 클램프 구동부(3)를 구동하고, 클램프 감지부(1a)로부터 클램프(6)가 감지되면 일정시간 작업시작경보가 발생하도록 경보발생부(5)를 제어하며, 슬라브 절단부(4)를 동작시켜 슬라브 절단을 수행하도록 제어한다. 또한, 제어부(2)는 슬라브 절단 작업이 완료되면 일정시간 작업완료경보를 발생하도록 경보발생부(5)를 제어한다.When the slab cutting command is input, the controller 2 drives the clamp driver 3 so that the clamp 6 rests on the surface of the slab. When the clamp 6 is detected from the clamp detector 1a, the operation start alarm for a predetermined time is output. The alarm generating unit 5 is controlled to generate, and the slab cutting unit 4 is operated to perform slab cutting. In addition, the controller 2 controls the alarm generator 5 to generate a work completion alarm for a predetermined time when the slab cutting operation is completed.

여기서, 제어부(2)는 클램프(6)가 슬라브(8) 표면에 안착되고 슬라브 에지 검출부(1b)로부터 슬라브 에지가 검출될 때까지 작업시작경보를 발생하도록 제어하고, 슬라브 절단작업이 완료되고 클램프(6)가 리프팅될 때까지 작업완료경보를 발생하도록 제어한다.Here, the control unit 2 controls the clamp 6 to generate a work start alarm until the clamp 6 is seated on the surface of the slab 8 and the slab edge is detected from the slab edge detector 1b, and the slab cutting operation is completed and the clamp Control to generate work completion alarm until (6) is lifted.

클램프 구동부(3)는 제어부(2)의 제어를 받아 클램프(6)를 구동하고, 슬라브 절단부(4)는 제어부(2)의 제어를 받아 슬라브(8)를 절단하며, 경보 발생부(5)는 제어부(2)의 제어를 받아 슬라브 절단작업 시작과 종료 시점에 경보를 발생한다.The clamp driving unit 3 drives the clamp 6 under the control of the control unit 2, and the slab cutting unit 4 cuts the slab 8 under the control of the control unit 2, and generates an alarm 5. Under the control of the control unit 2 generates an alarm at the start and end of the slab cutting operation.

이와 같이 구성된 본 실시예에 의한 연주설비에서의 토치커팅머신 감시 방법의 동작을 설명하면 다음과 같다.The operation of the torch cutting machine monitoring method in the performance equipment according to the present embodiment configured as described above is as follows.

도 1 내지 도 3에 도시한 바와 같이, 슬라브 절단 명령이 입력되면(S1), 클램프 구동부(3)를 구동하여 클램프(6)를 슬라브 표면에 안착시킨다(S2).1 to 3, when the slab cutting command is input (S1), the clamp driver 3 is driven to seat the clamp 6 on the slab surface (S2).

이어서, 클램프 감지부(1a)로부터 클램프(6)가 감지되면(S3), 경보 발생부(5)를 통해 슬라브 절단 작업시작경보를 발생시킨다(S4).Subsequently, when the clamp 6 is detected from the clamp detecting unit 1a (S3), the slab cutting operation start alarm is generated through the alarm generating unit 5 (S4).

이어서, 슬라브 에지 검출부(1b)로부터 슬라브 에지가 검출되는지 여부를 감시하고(S5), 슬라브 에지가 검출되면 작업시작경보를 중단한다(S6).Subsequently, it is monitored whether or not the slab edge is detected from the slab edge detector 1b (S5). If the slab edge is detected, the operation start alarm is stopped (S6).

이와같이, 작업시작경보는 클램프(6)가 감지된 후 발생하여 슬라브 에지가 검출될 때 중단된다.As such, the job start alarm occurs after the clamp 6 is detected and is stopped when the slab edge is detected.

이후, 슬라브 절단 작업이 완료되면(S7), 경보 발생부(5)를 통해 작업완료경보를 발생시킨다(S9).Then, when the slab cutting operation is completed (S7), through the alarm generating unit 5 generates a work completion alarm (S9).

이어서, 클램프 감지부(1b)로부터 클램프(6)가 리프팅되는 것이 감지되면(S9), 작업완료경보를 중단한다(S10).Subsequently, when it is detected that the clamp 6 is lifted from the clamp detecting unit 1b (S9), the work completion alarm is stopped (S10).

이와같이, 작업완료경보는 슬라브 절단 작업이 완료된 후 발생하여 클램프(6)가 리프팅될 때 중단된다.As such, the work completion alarm occurs after the slab cutting operation is completed and is stopped when the clamp 6 is lifted.

이와 같이, 본 실시예에 의한 연주설비에서의 토치커팅머신 감시 방법은, 클램프가 슬라브에 안착되어 슬라브 에지가 검출될 때까지 작업시작경보를 발생하고, 슬라브 절단작업이 완료되어 클램프가 리프팅될 때까지 작업완료경보를 발생함으로써 작업자가 경보시점에 토치커팅머신의 작업상황을 인지하여 불꽃의 소화 여부와 슬라브의 미절단 여부 확인을 통해 슬라브 미절단 여부를 감시한다.As described above, the method of monitoring the torch cutting machine in the performance equipment according to the present embodiment generates a work start alarm until the clamp is seated on the slab and the slab edge is detected, and when the slab cutting operation is completed and the clamp is lifted. By generating the work completion alarm up to the time, the worker recognizes the working condition of the torch cutting machine at the time of alarm and monitors whether the slab is not cut by checking whether the flame is extinguished and whether the slab is not cut.

상술한 바와 같이 본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 기술적 보호범위는 아래의 특허청구범위에 의해서 정하여져야 할 것이다.As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is merely exemplary, and various modifications and equivalent other embodiments of the present invention may be made by those skilled in the art. I understand that it is possible. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
