본 발명은 가열로의 로울러 자동중심장치에 관한 것으로, 더욱 상세하게는 전자부품 등을 이송하는 롤러가 열변형되더도 회동축과 항상 중심을 유지할 수 있어, 제품 이송을 흔들림 없이 원활히 수행할 수 있도록 발명된 것이다.The present invention relates to a roller automatic central device of a heating furnace, and more particularly, even if a roller for transferring electronic parts is thermally deformed, it can always be maintained at the center of the rotation shaft, so that product transportation can be performed smoothly without shaking. Invented.

일반적으로, 세라믹 파우더와 바인더 등의 소재를 가져다가 전자기기에 사용되는 모듈을 생산하기까지는 파우더를 가공하여야 하며, 세라믹 소재를 활용한 제품 생산에 있어 중요한 것은 세라믹 파우더를 균일성있게 가열로에서 소성 가공하는 기술에 있다.In general, the powder must be processed until it takes the materials such as ceramic powder and binder and produces the module used for electronic devices. The important thing in producing products using ceramic material is to uniformly fire the ceramic powder in the heating furnace. Is in the processing technology.

상기의 세라믹 파우더를 가공하는 과정에서 소성로에서 900 내지 1300℃ 온도로 열처리하는 공정이 있게 된다.In the process of processing the ceramic powder there is a process of heat treatment at a temperature of 900 to 1300 ℃ in the firing furnace.

가열로는 도 1 및 도 2에서와 같이 원통형의 봉 형상으로 이루어진 소정길이의 로울러(20)의 양단부에는, 본체(10)에 축지되는 회동축(30)의 일측부로 본체(10)에 구성된 구동수단(11)과 연결되며, 다른 일측은 로울러(20) 내경(22)에 끼워지도록 삽입부(32)가 형성되어 있다.As shown in FIGS. 1 and 2, a heating rod is formed at both ends of the roller 20 having a predetermined length in a cylindrical rod shape, and is configured to the main body 10 as one side of the rotation shaft 30 that is supported by the main body 10. Is connected to the means 11, the other side is formed with the insertion portion 32 to be fitted to the inner diameter 22 of the roller 20.

상기 로울러(20)의 내경(22)에 끼워진 삽입부(32)는 로울러(20)와 핀(22)에 의해 고정되어, 구동수단(11)에 의해 회동축(30)이 회전하면, 로울러(20)도 같이 회전하며, 상부에 놓여지는 전자기기를 이송하도록 하였다.The insertion part 32 fitted to the inner diameter 22 of the roller 20 is fixed by the roller 20 and the pin 22, and when the rotating shaft 30 is rotated by the driving means 11, the roller ( 20) was also rotated together to transfer the electronic equipment placed on the top.

이때, 로울러(20)의 상부에서 고온의 열을 발생시켜 로울러(20)를 따라 이송 되는 전자기기를 열처리하는 것이다.At this time, by generating a high temperature heat in the upper portion of the roller 20 is to heat the electronic device conveyed along the roller (20).

그러나, 전자기기에 사용되는 파우더를 가공하기 위해서는 고온의 열이 필요하며, 이때 제품을 이송시키는 롤러에도 상기의 고온이 지속적으로 전달되어 롤러는 열변형이 발생되기도 한다.However, in order to process the powder used in the electronic device, high temperature heat is required, and at this time, the high temperature is continuously transmitted to the roller for conveying the product, so that the roller may undergo thermal deformation.

즉, 전자부품을 이송하는 로울러에 고온이 지속적으로 전달되면, 로울러는 그 길이방향으로 팽창되나, 종래 로울러의 양 끝단부는 핀에 의해 고정되어 있어, 로울러 팽창 시 양측으로 팽창할 수 없어 중앙부가 하부로 휘어지는 폐단이 있었다.In other words, when the high temperature is continuously transmitted to the rollers for transporting electronic components, the rollers are expanded in the longitudinal direction, but both ends of the conventional rollers are fixed by pins, so that they cannot expand to both sides when the rollers are inflated. There was a bend to bend.

한편, 회전축에 끼워지는 로울러는 속이 빈 중공형으로 성형되는데, 끼움 공차를 위해 회전축의 삽입부 직경보다 로울러의 내경을 크게 제작하게 된다.On the other hand, the roller fitted to the rotary shaft is formed into a hollow hollow, the inner diameter of the roller is made larger than the diameter of the insertion portion of the rotary shaft for the fitting tolerance.

따라서, 회전축을 통해 회전력이 전달되어 구동되는 로울러는 회동될 때 유격에 의해 편심구동을 하게 된다.Therefore, the roller driven by the rotational force transmitted through the rotating shaft is eccentrically driven by play when rotated.

로울러가 편심회전을 하게 되면 그 위로 진행되는 전자제품 내지 파우더 등이 담겨져 있는 트레이가 심하게 흔들리게 된다.When the roller is eccentrically rotated, the tray containing the electronics or powder, which proceeds on top of it, will shake violently.

이때 파우더나 전자제품 들이 유동되며 파손에 의해 불량이 발생되는 원인이 되었던 것이다.At this time, the powder or electronics were flowed, which was the cause of the failure caused by breakage.

본 발명의 목적은, 열팽창이 발생되거나 끼움 공차에 의해 로울러가 편심 회전되는 것을 미연에 방지할 수 있도록 한 가열로를 제공하는데 있다.An object of the present invention is to provide a heating furnace which can prevent the roller from being eccentrically rotated due to thermal expansion or fitting tolerance.

본 발명의 다른 목적은, 가열로를 통과하는 제품이 흔들림에 의해 제품불량으로 생산되는 것을 미연에 방지하여 생산성을 향상시키도록 한 가열로를 제공하는데 있다.Another object of the present invention is to provide a heating furnace which improves productivity by preventing the product passing through the heating furnace from being produced as a product defect by shaking.

Is achieved by

한편, 슬라이드핀(60)은 고정돌기(62)의 다른 끝단부는 가동부재(50)의 경사면(51)을 따라 이동될 수 있도록 테이퍼부(61)를 형성하는 것이 바람직 하다.On the other hand, the slide pin 60 is preferably formed to the tapered portion 61 so that the other end of the fixing projection 62 can be moved along the inclined surface 51 of the movable member 50.

또, 회동축(30)의 삽입부(32) 끝단부에서 체결되어 수납홈(34)을 밀폐시키도 록 하는 캡(70)이 더 설치되는 것이 바람직하다.In addition, it is preferable that a cap 70 which is fastened at the end of the insertion portion 32 of the rotation shaft 30 to seal the receiving groove 34 is further installed.

따라서, 열팽창과 수축이 반복되거나 로울러(20)와 삽입부(32) 사이의 공차가 발생되더라도 항상 로울러(20)의 중심을 유지시킬 수 있어 제품 이송중에 전자제품이나 파우더 및 이들을 담고 있는 트레이가 흔들림 없이 안정된 이송이 가능하게 하는 것이다.Therefore, even if thermal expansion and contraction are repeated or a tolerance occurs between the roller 20 and the inserting portion 32, the center of the roller 20 can be maintained at all times, so that the electronics or powder and the tray containing them shake during product transfer. It is to enable a stable transfer without.

이하, 본 발명의 바람직한 실시 예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3 및 도 4에서 도시한 바와 같이, 속이 빈 원통형의 봉 형상으로 이루어진 소정길이의 로울러(20)의 양단부에는, 본체(10)에 축지되며 일측에 구성된 구동수단(11)과 체인으로 연결되는 회동축(30)이 삽입 설치된다.As shown in Figures 3 and 4, at both ends of the roller 20 of a predetermined length made of a hollow cylindrical rod shape, the chain is connected to the drive means 11, which is hung on the main body 10 and configured on one side. The rotating shaft 30 is inserted and installed.

상기 회동축(30)은 본체(10)에 구비된 베어링(B)에 고정축(31)이 축지되도록 하며, 그 내측으로는 단턱부(33)를 형성시켜, 회동축(30)의 이탈을 방지하였다.The rotating shaft 30 is fixed to the fixed shaft 31 on the bearing (B) provided in the main body 10, the stepped portion 33 is formed on the inner side, the separation of the rotating shaft 30 Prevented.

또, 회동축(30)은 로울러(20)의 양단에 각각 위치되어 지나, 일측에 위치되는 회동축(30)에는 구동수단(11)의 동력이 전달되는 체인과 대응되게 스프라켓이 고정축(31)의 외측에 결합되어 있다.In addition, the rotation shaft 30 is respectively located at both ends of the roller 20, the sprocket is fixed shaft 31 to the rotation shaft 30 located on one side to correspond to the chain to which the power of the drive means 11 is transmitted. Is coupled to the outside.

회동축(30)은 본체(10)에 일정간격을 두고 반복적으로 형성되어 있으며, 체 인에 의해 모든 회동축(30)이 연결되어 있어, 구동수단(11)의 동력을 전달받을 수 있게 하였다. Rotating shaft 30 is repeatedly formed at a predetermined interval on the main body 10, all the rotating shaft 30 is connected by a chain, so that the power of the drive means (11) can be transmitted.

따라서, 구동수단(11)을 통해 전달받은 동력이 체인과 스프라켓을 통해 수개의 회동축(30)을 동시에 회전시킬 수 있도록 하였다.Therefore, the power transmitted through the driving means 11 can rotate several rotating shafts 30 simultaneously through the chain and the sprocket.

회동축(30)의 선단으로는 원통형의 로울러(20) 내부로 끼워지는 삽입부(32)가 형성되어 있어, 회동축(30)이 회전하면 삽입부(32)에 끼워지는 로울러(20)가 같이 회전하는 것이다.At the tip of the rotating shaft 30, an inserting portion 32 is inserted into the cylindrical roller 20. When the rotating shaft 30 rotates, the roller 20 is fitted to the inserting portion 32. To rotate together.

이때, 회동축(30)의 삽입부(32)에는 소정 길이를 갖는 탄성부재(40)를 위치시키도록 하며, 상기 탄성부재(40)는 로울러(20)의 외면(21)과 회동축(30)의 단턱부(33)에 밀착고정되도록 하였다.At this time, the elastic member 40 having a predetermined length is positioned on the insertion part 32 of the rotation shaft 30, and the elastic member 40 is the outer surface 21 of the roller 20 and the rotation shaft 30. It was to be fixed in close contact with the step (33) of.

상기 회동축(30)의 삽입부(32)에는 내측으로 수납홈(34)이 구비되어 그 전방으로 가이드홈(35)이 중심방향으로 등분되게 수개 형성되게 하며, 수납홈(34)내로 가동부재(50)를 슬라이드 이동 가능하게 설치한다.The insertion part 32 of the rotation shaft 30 is provided with a receiving groove 34 inward so that the guide grooves 35 are formed to be equally divided in the center direction to the front thereof, and the movable member into the receiving groove 34. Install (50) so that it can slide.

상기, 가이드홈(35)에는 슬라이드핀(60)이 끼워진다.The slide pin 60 is fitted into the guide groove 35.

슬라이드핀(60)의 단부는 끝단부가 로울러(20)의 내경(22)에 밀착되는 고정돌기(62)가 형성되고, 타측 단부는 가동부재(50)의 경사면(51)을 따라 이동될 수 있도록 테이퍼부(61)가 형성된다.An end portion of the slide pin 60 is formed with a fixing protrusion 62 whose end portion is in close contact with the inner diameter 22 of the roller 20, and the other end thereof is movable along the inclined surface 51 of the movable member 50. The tapered portion 61 is formed.

그리고, 가동부재(50)는 전방으로 원뿔형상의 경사면(51)이 구비되어 있으며, 탄성부재(40)에 의해 항상 전방으로 이동되려는 힘이 작용되는데, 경사면(51)이 가이드홈(35)에 끼워진 슬라이드(60)의 테이퍼부(61)와 접촉된 상태로 전진하려 는 힘이 작용된다.And, the movable member 50 is provided with a conical inclined surface 51 to the front, the force to be always moved forward by the elastic member 40, the inclined surface 51 is fitted into the guide groove 35 The force to move forward in contact with the tapered portion 61 of the slide 60 is applied.

따라서, 각 슬라이드핀(60)들은 항상 로울러(20)의 내경과 일정한 탄성력으로 밀착하려는 힘이 작용된다.Therefore, the slide pins 60 are always in close contact with the inner diameter and constant elastic force of the roller 20 is applied.

즉, 수납홈(34)내에서 가동부재(50)의 경사면(51)과 슬라이드핀(60)의 테이퍼부(61)가 서로 맞닿은 상태에서 가동부재(50)가 탄성부재(40)에 의해 전방으로 이동되면 슬라이드핀(60)는 가이드홈(35)을 따라 상부로 이동된다.That is, the movable member 50 is moved forward by the elastic member 40 in a state where the inclined surface 51 of the movable member 50 and the taper portion 61 of the slide pin 60 abut against each other in the receiving groove 34. When moved to the slide pin 60 is moved upward along the guide groove (35).
