이와 같이 구성된 본 발명을 상세히 설명하면 다음과 같다.Referring to the present invention configured as described in detail as follows.

먼저, 원료를 수송한 후 복귀하는 리턴벨트(5)는 도3에 나타낸 바와 같이 리턴롤러(3)의 상면에 접촉된 상태로 이동되는 것이며, 이때 리턴롤러(3)는 스탠드(2)에 설치된 상태로 회전되는 것이다.First, the return belt 5 to return after transporting the raw material is moved in contact with the upper surface of the return roller 3, as shown in Figure 3, wherein the return roller 3 is installed on the stand (2) It is rotated to a state.

또한 상기 리턴벨트(5)에 유동이 발생되면 리턴벨트(5)를 지지하는 스탠드(2)는 중심축(6)을 중심으로 회전되면서 리턴벨트(5)가 안정적으로 이동될 수 있도록 안내하게 되는 것이다.In addition, when a flow is generated in the return belt 5, the stand 2 supporting the return belt 5 is rotated about the central axis 6 to guide the return belt 5 to be stably moved. will be.

한편, 상기 리턴벨트(5)가 어느 일측으로 편심된 상태로 이동하는 사행이 발생될 경우에는 도4에 나타낸 바와 같이 리턴벨트(5)의 측면이 가이드롤러(4)에 접촉된 상태로 이동되는 것이고, 이때 상기 가이드롤러(4)는 연속적으로 회전되면서 리턴벨트(5)의 이동을 안내하게 되는 것이다.On the other hand, when meandering occurs in which the return belt 5 is eccentrically moved to one side, as shown in FIG. 4, the side surface of the return belt 5 is moved in contact with the guide roller 4. At this time, the guide roller 4 is to be continuously rotated to guide the movement of the return belt (5).

상술한 바와 같이 가이드롤러(4)에 리턴벨트(5)가 접촉된 상태로 장시간 이 동되어, 그 접촉면에 마찰열이 발생하면, 프레임(1)의 양 측면에 지지부재(11)를 매개로 설치된 온도측정수단(10)에 마찰열이 측정된다.As described above, when the return belt 5 is in contact with the guide roller 4 for a long time, and friction heat is generated on the contact surface, the support members 11 are installed on both sides of the frame 1. Friction heat is measured by the temperature measuring means 10.

이와 같이 측정된 마찰열은 작업자가 육안으로 확인할 수 있도록 온도측정수단(10)에는 설치된 표시부(12)를 통하여 제공됨과 동시에 제어부(30)로 전성된다.The frictional heat measured as described above is provided to the temperature measuring means 10 through the display unit 12 installed at the same time and is transmitted to the controller 30 so that the operator can visually check.

상기 제어부(30)에서는 전송된 온도값과 설정값을 비교하여 전송된 온도값이 설정값보다 클 경우에는 냉각수 공급관(20)에 설치된 공급밸브(21)가 개방되도록 제어신호를 발생하게 되는 것이며, 그 제어신호에 의해서 공급밸브(21)가 개방되면, 냉각수 공급관(20)에 설치된 복수개의 분사노즐(22)을 통하여 냉각수가 분사된다.The control unit 30 generates a control signal to open the supply valve 21 installed in the coolant supply pipe 20 when the transmitted temperature value is greater than the set value by comparing the transmitted temperature value with the set value. When the supply valve 21 is opened by the control signal, the coolant is injected through the plurality of injection nozzles 22 provided in the coolant supply pipe 20.

이와 같이 분사되는 냉각수는 리턴벨트(5)와 가이드롤러(4)의 접촉면은 물론, 스탠드(2)로 분사되어 마찰로 인하여 상승된 온도를 감소시키게 되므로 화재가 발생되는 것을 미연에 방지하게 되는 것이다.The cooling water sprayed as described above is to prevent the fire from occurring in advance because the contact surface of the return belt 5 and the guide roller 4 is sprayed to the stand 2 to reduce the elevated temperature due to friction. .

이와 같이 본 발명은 리턴벨트가 사행되어 그 리턴벨트의 측면이 가이드롤러에 접촉된 상태로 장시간 이동될 때 그 접촉면의 마찰로 인하여 상승되는 온도를 감지함은 물론 감지된 온도값이 설정값 보다 높을 경우에는 냉각수를 자동으로 분사시켜 화재로 인한 안전사고를 미연에 방지할 수 있는 특유의 효과가 있다.As described above, the present invention senses the temperature rising due to friction of the contact surface when the return belt is meandered and the side of the return belt is moved for a long time in contact with the guide roller, and the detected temperature value is higher than the set value. In this case, the cooling water is automatically sprayed to have a unique effect of preventing a fire accident.
