본 발명은 컨베이어 시스템의 체인롤러 가동장치에 관한 것으로서, 더욱 상세하게는 체인롤러의 역방향 구동시 체인롤러가 특정위치에서 꺾어지면서 롤러가이드레일이 파손되는 것을 방지하기 위한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chain roller moving apparatus for a conveyor system, and more particularly, to prevent a roller guide rail from being broken when a chain roller is bent at a specific position during reverse driving of the chain roller.

일반적으로 대부분의 공장에서는 제품의 대량 생산을 위하여 주요 공정이 라인을 따라 연속적으로 이루어지도록 하고 있으며, 이러한 생산라인이나 제조라인에서는 원자재, 기계부품, 화물 등을 연속적으로 운반할 수 있도록 컨베이어 시스템을 사용하고 있다. 이와 같이 각 라인을 컨베이어 시스템으로 연결하게 되면, 생산효율이 획기적으로 향상되고 대량생산이 가능해진다.Generally, in most factories, major processes are continuously performed along the lines for mass production of products. In such production lines and manufacturing lines, conveyor systems are used to convey raw materials, machine parts, and cargoes continuously . By connecting each line to the conveyor system in this way, the production efficiency is remarkably improved and mass production becomes possible.

이러한 컨베이어 시스템은 구조나 구동방식 등에 따라 다양하게 구분되는데, 대표적으로 벨트 컨베이어(belt conveyor), 체인 컨베이어(chain conveyor), 롤러 컨베이어(roller conveyor), 트롤리 컨베이어(trolley conveyor) 등이 있다. 그리고 자동차, 전자, 전기 제품의 부품생산라인, 조립라인, 검사라인 등에는 레일 프레임과 레일 프레임을 따라 연속적으로 이동하며 부품 등을 이송해주는 체인롤러로 이루어진 컨베이어 시스템이 사용되고 있으며, 이러한 체인롤러 컨베이어 시스템은 내구성 및 안전성이 우수한 장점이 있다.Such a conveyor system is divided into various types according to the structure, driving type, etc. Typically, there are a belt conveyor, a chain conveyor, a roller conveyor, and a trolley conveyor. A conveyor system comprising chain rollers for continuously moving parts along a rail frame and a rail frame is used for parts production lines, assembly lines, inspection lines, etc. of automobiles, electronics, and electrical products. Has advantages of excellent durability and safety.

이러한 체인롤러 컨베이어 시스템은 도 1에 도시된 바와 같이, 다수의 롤러가 체인에 의해 연결되어져 있는 체인롤러(1)가 하나의 사이클을 이루어 감겨져 있으며, 상기 체인롤러(1) 양측에는 구동스프라켓(2)과 체인가이드(3)가 구성되어져 있으며, 구동스프라켓(2) 하부에는 체인롤러(1)에 텐션을 유지시키기 위한 텐션유지스프링(4)이 구성되고, 상부에는 체인롤러(1)의 이동을 가이드하기 위한 롤러 가이드레일(5)이 구성되어지게 된다.1, a chain roller 1, in which a plurality of rollers are connected by a chain, is wound in a single cycle. On both sides of the chain roller 1, a drive sprocket 2 A tension guide spring 4 for holding tension on the chain roller 1 is constituted below the drive sprocket 2 and a movement of the chain roller 1 is formed on the upper part thereof The roller guide rails 5 for guiding are constructed.

이러한 구성을 이루는 종래 체인롤러 컨베이어 시스템은 구동모터(미도시)의 동력을 전달받은 구동스프라켓(2)이 정방향으로 회동되어지면 체인롤러(1)가 이동되어지면서 부품 등을 일방향으로 이송시키는 기능을 수행하게 된다.In the conventional chain roller conveyor system having such a configuration, when the drive sprocket 2, which receives the power of the drive motor (not shown), is rotated in the forward direction, the chain roller 1 is moved and the parts are transported in one direction .

한편, 투입과 배출이 이루어져야 하는 엘리베이터 안쪽에 설치되는 컨베이어의 경우 정방향 구동과 역방향 구동이 교번하여 이루어지게 되는데 정방향 구동이 이루어지는 과정에서 구동스프라켓(2)의 역방향 구동이 이루어지게 되면, 구동스프라켓(2)의 하부에 위치하는 체인롤러(1)가 순간적으로 이완되어 롤러 가이드레일의 선단부에서 체인롤러(1')의 꺾임현상이 발생되면서 롤러 가이드레일(5)의 선단부에 체인롤러(1')의 걸림 및 롤러가이드(5)의 변형 내지는 파손이 발생 되는 문제점이 있었다.
On the other hand, in the case of the conveyor installed inside the elevator in which the loading and discharging are to be performed, the forward drive and the reverse drive are alternated. When the drive sprocket 2 is driven in the reverse direction during the forward drive, The chain roller 1 located at the lower portion of the roller guide rail 5 is instantaneously loosened so that the chain roller 1 'is bent at the front end of the roller guide rail and the chain roller 1' There is a problem that deformation or breakage of the engaging and roller guide 5 occurs.

본 발명은 상기한 종래 체인롤러 역회전 구동에서 발생 되는 문제점을 개선하기 위해 제안된 것으로서, 체인롤러의 순간적인 이완작용이 이루어지더라도 텐션유지스프링이 압축되는 것이 방지되어 질 수 있는 구조를 제공함으로써 체인롤러가 롤러가이드에 걸리거나 롤러가이드가 파손되는 현상이 방지되도록 하는데 목적이 있다.

먼저, 본 발명의 일 실시 예에 따른 컨베이어 시스템의 체인롤러 역회전 가동장치 구조를 살펴보면, 다수의 롤러가 상호 체인에 의해 연결되어 하우징 본체(10) 주변을 따라 하나의 연속된 사이클을 이루며 구비되는 체인롤러(20)와, 상기 체인롤러(20)에 구동력을 전달하기 위해 하우징 본체(10) 일측에 구성되는 구동스프라켓(30)과, 상기 체인롤러(20)의 구동을 지지하기 위해 하우징 본체(10) 타측에 구성되는 체인가이드(40)와, 상기 체인롤러(20)의 이동을 가이드하기 위해 구동스프라켓(30)과 체인가이드(40) 사이에 수평으로 구성되는 롤러 가이드레일(25)과, 상기 구동스프라켓(30)의 하부에 수직방향으로 장착되어 체인롤러(20)가 일정 텐션을 유지하도록 지지하는 텐션스프링(50)과, 상기 텐션스프링(50)의 하단부에 결합되어져 있는 텐션지지블럭(51)과, 상기 텐션지지블럭(51)의 하부에 결합 구성되어져 있으며, 반원형상을 이루어 체인롤러(20)가 가이드되는 텐션가이드(52)와, 상기 텐션지지블럭(51)의 상승을 방지하기 위해 하우징 본체(10)에 연결 구성된 상승방지스토퍼(60)로 구성된다.First, according to an embodiment of the present invention, a plurality of rollers are connected to each other through a chain to form a continuous cycle along the circumference of the housing body 10 A driving sprocket 30 formed at one side of the housing main body 10 to transmit a driving force to the chain roller 20 and a housing main body 10 for supporting the driving of the chain roller 20, A roller guide rail 25 formed horizontally between the drive sprocket 30 and the chain guide 40 for guiding the movement of the chain roller 20, A tension spring 50 mounted vertically to a lower portion of the drive sprocket 30 to support the chain roller 20 to maintain a constant tension and a tension spring 50 coupled to a lower end of the tension spring 50 51), A tension guide 52 coupled to a lower portion of the support block 51 for guiding the chain roller 20 in a semicircular shape and a housing main body 10 (See FIG. 1).

특히, 상승방지스토퍼(60)에는 제1톱니부(60a)가 형성되어져 있으며, 상기 제1톱니부(60a)와 대응되는 텐션지지블럭(51)의 측벽면에는 제2톱니부(51a)가 형성되어져 있어 상호 간에 치합상태가 유지되는 것 확인할 수 있다.The first toothed portion 60a is formed on the rising prevention stopper 60 and the second toothed portion 51a is formed on the side wall surface of the tension support block 51 corresponding to the first toothed portion 60a So that the meshing state can be maintained.

이때, 제1,2톱니부(51a,60a)는 텐션지지블럭(51)의 하향 이동은 가능하나 상승 이동만이 방지되도록 편심된 형상을 이루게 된다.At this time, the first and second toothed portions 51a and 60a can be downwardly moved but can be eccentrically shaped so as to prevent only the upward movement of the tension support block 51.

또한, 상승방지스토퍼(60)의 상단부는 회동이 가능하도록 하우징본체(10)와 힌지핀(61)에 의해 연결 구성되고, 상기 상승방지스토퍼(60) 중단에는 제1,2톱니부(60a,51a)의 밀착력을 증대시키기 위한 탄성스프링(62)이 연결 구성된다.The upper end of the ascent prevention stopper 60 is connected to the housing main body 10 by a hinge pin 61 so that the upper end of the ascent prevention stopper 60 can be pivoted and the first and second toothed portions 60a, And an elastic spring 62 for increasing the adhesion of the elastic members 51a and 51a.

그리고, 상승방지스토퍼(60)의 하단부에는 일정 각도(θ)의 경사를 이루는 손잡이부(63)가 구비됨이 바람직하다.It is preferable that the lower end of the ascent prevention stopper 60 is provided with a handle 63 which is inclined at a certain angle?

도면 중 미설명 부호 11은 상부가이드이고, 12는 하부가이드를 각각 나타낸다.Reference numerals 11 and 12 denote an upper guide and a lower guide, respectively.

이와 같은 구조를 이루는 본 발명 컨베이어 시스템의 체인롤러 역회전 가동장치 구동에 따른 작용효과를 살펴보기로 한다.Hereinafter, the operation and effect of driving the chain roller reverse rotation device of the conveyor system of the present invention will be described.

본 실시 예에서의 컨베이어 시스템은 구동스프라켓(30)과 체인 가이드(40) 사이에 체인롤러(20)가 사이클을 이루어 감겨진 상태에서 구동모터(미도시)로 부터 동력을 전달받은 구동스프라켓(30)이 정방향으로 회동되어짐에 따라 체인롤러(20)의 구동이 이루어지면서 하우징 본체(10)의 상면을 따라 생산부품 등을 이송시키게 된다.The conveyor system according to the present embodiment includes a drive sprocket 30 that receives power from a drive motor (not shown) in a state where the chain roller 20 is wound in a cycle between the drive sprocket 30 and the chain guide 40 The chain roller 20 is driven and the production parts and the like are transferred along the upper surface of the housing main body 10.

이때, 하우징 본체(10)의 일측에는 텐션스프링(50)에 의해 탄성 지지되는 텐션가이드(52)가 구성되어져 있기 때문에 체인롤러(20)가 일정 탄성력으로 지지되어 쳐지는 현상을 방지할 수 있게 된다.At this time, since the tension guide 52 elastically supported by the tension spring 50 is formed on one side of the housing main body 10, the chain roller 20 can be prevented from being stuck due to a certain elastic force .

한편, 이러한 동작과정에서 부품을 반대방향으로 이송시키고자 하는 경우에는 구동스프라켓(30)에 역방향 회동력이 작용되어지게 되어 체인롤러(20)의 역방향 구동이 발생되어지게 된다.Meanwhile, when the component is to be moved in the opposite direction in this operation process, the reverse rotation force is applied to the drive sprocket 30, and the reverse drive of the chain roller 20 is generated.

이러한 역방향 구동이 시작되어지게 되면 체인롤러(20) 중 구동스프라켓(30)의 하부측에 연결되어진 부위에 순간적인 인장력이 발생하게 되어 텐션가이드(52)에 상승작용력이 가해지게 된다.When the reverse driving is started, an instantaneous tensile force is generated at a portion connected to the lower side of the drive sprocket 30 among the chain rollers 20, so that a rising force is applied to the tension guide 52.

그러나, 본 발명에서는 상승방지스토퍼(60)에 의해 텐션가이드(52)의 상승 동작이 방지됨으로써 체인롤러(20)의 일측에 작용하는 인장력을 지지할 수 있게 된다.However, in the present invention, the lifting operation of the tension guide 52 is prevented by the lifting prevention stopper 60, so that it is possible to support the tensile force acting on one side of the chain roller 20.

즉, 텐션가이드(52) 상부에 구성된 텐션지지블럭(51)은 상승방지스토퍼(60)와 제1,2톱니부(51a,60a)에 의해 상호 치합된 상태를 이루고 있으며, 상승방지스토퍼(60)는 탄성스프링(62)의 스프링 작용력에 의해 텐션지지블럭(51)과 밀착 상태가 유지됨으로서 텐션스프링(50)에 압축력이 작용되는 것을 방지할 수 있게 된다.That is, the tension supporting block 51 formed on the tension guide 52 is engaged with the rising prevention stopper 60 and the first and second toothed parts 51a and 60a, and the rising prevention stopper 60 Is kept in close contact with the tension supporting block 51 by the spring force of the elastic spring 62, so that the compression spring can be prevented from being applied to the tension spring 50.

따라서, 텐션스프링(50)은 하향으로의 길이가 늘어나는 유동작용은 이루어지는 반면, 상향으로의 압축작용이 방지됨으로써 체인롤러(20)가 특정 부위에서 꺾어지는 현상이 방지되어 질 수 있게 된다.Accordingly, while the tension spring 50 has a flow action to increase the downward length, the downward compression action is prevented, and the chain roller 20 can be prevented from bending at a specific portion.

한편, 체인롤러(20)의 보수를 위해 도 4에서와 같이 작업자가 손잡이부(63)를 잡고 바깥측으로 힘을 가하게 되면 상승방지스토퍼(60)가 힌지핀(61)을 축으로 회동되면서 제1톱니부(60a)와 제2톱니부(51a)가 이격되어지게 된다.4, when the worker grasps the handle 63 and exerts a force on the outside, the lift preventing stopper 60 is rotated about the hinge pin 61 to rotate the first The teeth portion 60a and the second toothed portion 51a are separated from each other.

그리고, 손잡이부(63)를 놓게 되면 탄성스프링(62)의 탄성작용에 의해 다시 상승방지스토퍼(60)와 텐션지지블럭(51)의 치합상태가 유지되어 질 수 있게 되는 것이다.In addition, when the handle 63 is placed, the engagement between the lift preventing stopper 60 and the tension supporting block 51 can be maintained again by the elastic action of the elastic spring 62.

따라서, 본 발명에 의하면 컨베이어 시스템의 정방향 동작 과정에서 순간적인 역방향 구동이 이루어졌을 때 텐션스프링(50)이 압축되어지는 현상을 방지함으로써 체인롤러(20)가 롤러가이드 레일(25)에 걸리거나 롤러가이드 레일(25)이 파손되는 현상이 방지되어 질 수 있게 됨을 알 수 있다.
