본 고안은 체인 전동기구의 과부하 검출장치에 관한것이다.The present invention relates to an overload detection device for a chain drive.

벨트 콘베이어등을 구동시키는 체인 전동기구에 있어서, 벨트 콘베이어의 주행 속도를 일정하게 해주기 위하여, 체인 스프라켓의 보스부에 토오크 리미트가 장치되고 있다.In the chain transmission mechanism which drives a belt conveyor etc., in order to make the traveling speed of a belt conveyor constant, the torque limit is provided in the boss | hub part of a chain sprocket.

이 토오크리미트는 스프라켓에 대하여 클러치 작용을 행하는 것으로, 모우터의 회전력이 체인에 일정한 속력으로 전달되도록 하여주는 것이나, 과부하의 검출을 행할수는 없게 되어 있다.The torque limit acts as a clutch against the sprocket, which allows the rotational force of the motor to be transmitted to the chain at a constant speed, and cannot detect the overload.

본 고안의 목적은 벨트 콘베이어 등에 적용되는 체인 전동기구의 안전장치로서, 체인에 가해지는 과부하를 적시에 검출하여 이를 경보할수 있게 한 체인 전동기구의 과부하 검출 장치를 제공함에 그 목적이 있다.An object of the present invention is to provide an overload detection apparatus for a chain transmission mechanism that can detect an overload applied to a chain in a timely manner and to alarm the chain transmission mechanism.

이에 따라 본 고안은 스프링에 의해 탄성 지지되어 하우징에서 출몰 가능하게 설치된 요크의 상단에 아이들 스프라켓을 회전 가능하게 추축 연결하고, 요크의 하측방에 가이드핀을 직교상으로 배치하여 하우징의 외측으로 도출시킴과 동시에 가이드핀의 승강 행정 사이로 리미트 스윗치를 위치 조절 가능하게 부착하여 구성됨을 특징으로 한다.Accordingly, the present invention is pivotally connected to the idle sprocket rotatably connected to the upper end of the yoke that is elastically supported by the spring and installed in the housing, and guide guides are arranged orthogonally to the lower side of the yoke to draw out the housing. And at the same time characterized in that it is configured by attaching the limit switch position adjustable between the lifting stroke of the guide pin.

이하 본 고안을 첨부 도면에 따라 실시예로서 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제 1 도에서 보호(1)은 하우징이며, 하측의 고정판(2)상에 장착된다.In FIG. 1 the protection 1 is a housing and is mounted on the lower fixing plate 2.

하우징(1)의 내부에는 요크(3)이 슬라이드 가능하게 삽입 설치됨과 아울러, 이 요크(3)의 하측부에는 가이드핀(4)가 돌출되어, 하우징(1)의 외주측 가이드 홈(5)를 통하여 노출된다.The yoke 3 is slidably inserted into the housing 1, and a guide pin 4 protrudes from the lower side of the yoke 3 to guide the outer circumferential side guide groove 5 of the housing 1. Exposed through.

따라서 가이드홈(5)는 요크(3)의 승강 행정을 규제하여 주게되고, 이때의 승강 행정 도중에는 리미트 스윗치(6)이 전기한 가이드핀(4)에 의해 간섭될수 있게 배치된다.Therefore, the guide groove 5 is provided to regulate the lifting stroke of the yoke 3, and the limit switch 6 is arranged to be interfered by the guide pin 4 described above during the lifting stroke.

한편, 요크(3)의 상단에는 아이들 스프라켓(7)이 축(8)에 의해 회전 가능하게 지지되어 있으며, 또한 제 2 도의 도시와같이 요크(3)의 하단은 하우징(1)의 내부에 설치된 탄발스프링(9)에 의해 탄성지지되어, 요크(3)은 항상 돌출된 상태로 유지되어 진다.On the other hand, the idle sprocket 7 is rotatably supported by the shaft 8 at the upper end of the yoke 3, and the lower end of the yoke 3 is installed inside the housing 1 as shown in FIG. Elastically supported by the ball spring 9, the yoke 3 is always kept in a protruding state.

이와 같이 구성되는 본 고안은 제 3 도의 도시와 같이 모우터(A)에 의해 회전되어 벨트콘베이어를 구동하는 구동 스프라켓(B)와 종동 스프라켓(C)사이에 가설된 체인(D)로 전술한 아이들 스프라켓(7)이 맞물려지도록 배치하여 사용된다.The present invention constituted as described above has the above-mentioned idler as a chain D hypothesized between the drive sprocket B and the driven sprocket C, which are rotated by the motor A to drive the belt conveyor, as shown in FIG. It is used by arranging the sprocket 7 to be engaged.

상기 시스팀에서 벨트콘베이어에 과 하중이 적재되거나, 반송물이 적체되어 과부하가 걸리게 되면, 아이들 스프라켓(7)이 체인(D)의 장력 변화에 의해 요크(3)을 하우징(1)로 내리 눌러주게된다.When the overload is loaded on the belt conveyor in the system, or the load is accumulated and overloaded, the idle sprocket 7 pushes the yoke 3 down to the housing 1 due to the tension change of the chain D. .

이로 인하여 요크(3)은 하우징(1)내의 탄발스프링(9)에 저항하여 하강하면서 가이드핀(4)가 승강 행정내에 위치하는 리미트 스윗치(6)을 간섭시키게 된다.As a result, the yoke 3 descends against the ball spring 9 in the housing 1 and interferes with the limit switch 6 in which the guide pin 4 is located in the lifting stroke.

따라서 리미트 스윗치(6)은 일정 조건이 일치되면 가이드핀(4)에 의해 신호를 발생하게 되므로, 경보장치 또는 모우터의 정지 동작원으로 사용될수 있다.Therefore, the limit switch 6 generates a signal by the guide pin 4 when a predetermined condition is matched, and thus can be used as a stop operation source of an alarm device or a motor.

즉, 과부하시 요크(3)이 체인(D)의 장력으로 하강될때, 가이드핀(4)가 리미트 스윗치(6)을 스윗칭-온 함으로써, 리미트 스윗치(6)에 접속된 통상의 경보장치(도시생략)가 과부하 발생을 알려줌과 동시에, 구동모우터(A)를 정지시키게 할수 있는 것이다.That is, when the yoke 3 is lowered to the tension of the chain D during overload, the guide pin 4 switches on the limit switch 6 so that the normal alarm device connected to the limit switch 6 ( (Not shown) notifies the occurrence of the overload, and can stop the driving motor (A).

상술한 바와 같이 본 고안에 의하면 벨트 컨베이어의 과부하를 검출하여 구동원의 손상을 미연에 방지할수 있는 효과를 갖는다.As described above, according to the present invention, the overload of the belt conveyor is detected to have an effect of preventing damage to the driving source.
