Description

벨트 컨베이어의 롤러 파손 감지 장치{An apparatus for detecting the damage of rollers in a belt conveyor}An apparatus for detecting the damage of rollers in a belt conveyor}

본 발명은 벨트 컨베이어의 롤러 파손 감지 장치에 관한 것으로서, 롤러의 내부로 공급되는 고압공기의 압력변화에 의해 롤러의 파손이 감지될 수 있도록 된 벨트 컨베이어의 롤러 파손 감지 장치에 관한 것이다.The present invention relates to a roller breakage detection device of a belt conveyor, and to a roller breakage detection device of a belt conveyor that is capable of detecting the breakage of the roller by the pressure change of the high pressure air supplied into the roller.

생산 설비에 널리 이용되는 벨트 컨베이어는 도1에 개략적으로 도시된 것처럼 다수개의 롤러(Roller)에 지지되어 무한 궤도 운동되는 벨트(B)를 이용하여 다량의 수송물(C)을 이송시키는데 매우 효과적이다.Belt conveyors widely used in production facilities are very effective for transporting large quantities of consignments (C) using a belt (B), which is supported by a plurality of rollers and is infinitely orbitally moved as shown schematically in FIG. .

상기의 롤러는, 벨트(B)의 무한 궤도를 형성시키는 구동풀리(110)와 종동풀리(120), 여러 개소에 설치되어 벨트(B)의 하부를 지지하는 스냅풀리(130), 벨트(B)의 장력을 조절하도록 구비된 테이크업 풀리(140) 및, 벨트(B)의 경로를 변경시킬 수 있도록 벨트(B)를 지지하도록 구비된 밴드 풀리(150) 등으로 이루어진다. 그리고, 상기 구동풀리(110)는 미도시된 구동모터에 의해 회전 구동된다.Said roller is provided in the drive pulley 110 and the driven pulley 120 which form the infinite track of the belt B, the snap pulley 130 which is installed in several places, and supports the lower part of the belt B, and the belt B. Take-up pulley 140 provided to adjust the tension of the) and the band pulley 150 provided to support the belt (B) to change the path of the belt (B). In addition, the driving pulley 110 is rotationally driven by a driving motor (not shown).

이러한 벨트 컨베이어의 롤러들은 벨트(B)와의 마찰에 의한 마모 등에 의해 파손되고, 종래에는 주요한 롤러인 구동풀리(110)와 종동풀리(120) 등에 대하여만 작업자가 직접 육안이나 별도의 점검기구를 이용하여 주기적으로 점검하는 것으로 노동 생산성 측면에서 바람직하지 못한 것이었다.The rollers of the belt conveyor are damaged by abrasion due to friction with the belt (B), and in the related art, the operator directly uses the naked eye or a separate inspection mechanism only for the main pulley 110 and the driven pulley 120. Regular inspections were undesirable in terms of labor productivity.

게다가, 정밀한 점검이 이루어지는 경우에는 벨트 컨베이어의 가동을 정지시켜야 하기 때문에 설비가동 효율이 저하된다는 문제점을 갖는 것이었다.In addition, when a precise inspection is made, the belt conveyor conveyor has to be stopped, which causes a problem in that the equipment operating efficiency is lowered.

또한, 롤러들이 벨트 사행이나 수송물의 낙하 등의 원인에 의해 비정상적으로 마모 및 파손되는 경우에는, 이를 적기에 발견하는 것이 거의 불가능하고, 이에의하여 고가의 벨트(B)가 파손되어 벨트 컨베이어의 가동이 갑자기 정지되는 등 벨트 컨베이어를 안정적으로 가동시키는 것이 불가능한 문제점을 갖는 것이었다.In addition, when the rollers are abnormally worn and damaged due to belt meandering or dropping of transport materials, it is almost impossible to find them in a timely manner, whereby the expensive belt B is broken and the operation of the belt conveyor is prevented. It was a problem that it was impossible to stably operate the belt conveyor such as sudden stop.

본 발명은 이러한 종래의 문제점을 해결하기 위한 것으로서, 벨트 컨베이어에 구비된 롤러들의 각각이 마모 등에 의해 파손되는 것을 실시간으로 감지하여 롤러들이 파손된 경우 신속한 후속조치를 취할 수 있도록 된 벨트 컨베이어의 롤러 파손 감지 장치를 제공함에 그 목적이 있다.The present invention is to solve the conventional problems, the roller breakage of the belt conveyor to be able to take a quick follow-up action when the rollers are broken in real time that each of the rollers provided in the belt conveyor is damaged by wear, etc. The object is to provide a sensing device.
