본 발명은 가열로의 이송로울러 구동장치에 관한 것으로, 더욱 상세하게는 세라믹 롤러의 상부에 놓여져 이송되는 전자부품을 열처리하는 과정에서 열에 의해 이송롤러가 변형되는 것을 방지할 수 있도록 발명된 것이다.The present invention relates to a transfer roller driving apparatus of a heating furnace, and more particularly, to invent a transfer roller to be deformed by heat in the process of heat-treating an electronic component placed on top of a ceramic roller.

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 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 in the electronic device. The important thing in the production of products using the ceramic material is the technology to process the ceramic powder uniformly. have.

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

즉, 도 1 및 도 2에서와 같이 원통형의 봉 형상으로 이루어진 소정길이의 로울러(20)의 양단부에는, 후레임(10)에 축지되는 회동축(30)의 일측부로 후레임(10)에 구성된 구동수단(11)과 연결되며, 다른 일측은 로울러(20) 내부에 끼워지도록 삽입부(32)가 형성되어 있다.That is, as shown in Figs. 1 and 2, the driving means formed on the frame 10 as one side of the rotation shaft 30 is supported on the frame 10 at both ends of the roller 20 of a predetermined length having a cylindrical rod shape. Is connected to (11), the other side is formed with an insertion portion 32 to be fitted in the roller (20).

상기의 로울러(20) 내부에 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 inserted into the roller 20 is fixed by the roller 20 and the pin 22. When the rotation shaft 30 is rotated by the driving means 11, the roller 20 is also rotated. Rotating together, it was to transfer the electronic equipment placed on the top.

이때, 로울러(20)의 상부에서 고온의 열을 발생시켜 로울러(20)를 따라 이송되는 전자기기를 열처리 할 수 있는 것이다.At this time, by generating a high temperature heat in the upper portion of the roller 20 is to heat treatment the electronic device is transported along the roller (20).

그러나, 전자기기에 사용되는 파우더 또는 각종 부품을 완성하기 위해서는 고온의 열로 가열하는 가열공정이 필요하며, 이때 제품을 이송시키는 롤러에도 열이 지속적으로 전달되어 롤러가 길이방향으로 신장되고, 다시 가열로의 작동이 멈추게 되면 수축되는 등 변형이 자주 발생된다.However, in order to complete the powder or various parts used in the electronic device, a heating process for heating with high temperature heat is required. At this time, the heat is continuously transferred to the roller for conveying the product so that the roller is elongated in the longitudinal direction, and the heating furnace again. When the operation stops, deformation occurs frequently.

이와 같이 전자부품을 이송하는 로울러에 고온이 지속적으로 전달되어 로울러가 그 길이방향으로 팽창 될 때 로울러의 양 끝단부가 핀이나 스냅링 등의 결합요소에 의해 고정되어 있으므로 로울러의 중앙부가 휘어지게 된다.In this way, when the high temperature is continuously transmitted to the roller for transporting the electronic components and both ends of the roller are fixed by a coupling element such as a pin or a snap ring when the roller is expanded in the longitudinal direction, the center portion of the roller is bent.

따라서, 고온이 전달되는 부위의 로울러는 고온을 견딜 수 있는 고가의 재질로 선택하기도 하나, 제품의 비용부담이 가중되는데도 불구하고 장시간 사용시 로울러가 열변형되는 것은 해소하지 못하는 등의 문제점이 있었다.Therefore, the roller of the site where the high temperature is transmitted may be selected as an expensive material that can withstand the high temperature, and although the cost burden of the product is increased, there is a problem that the roller is not thermally deformed when used for a long time.

본 발명의 목적은, 고온의 열이 지속적으로 전달되어 로울러가 길이방향으로 신축되더라도, 그 열변형량을 흡수하여, 로울러의 변형을 방지하고, 직진상태를 유지시킬 수 있도록 한 가열로를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a heating furnace which is capable of absorbing the thermal strain, preventing deformation of the roller, and maintaining a straight state even when the high temperature heat is continuously transmitted and the roller is stretched in the longitudinal direction. .

본 발명의 다른 목적은, 이송로울러의 설치 및 분해가 용이하도록 된 가열로를 제공하는데 있다.Another object of the present invention is to provide a heating furnace which facilitates installation and disassembly of a transfer roller.

이러한 본 발명의 목적은, 가열로의 형틀을 이루는 후레임(10)과,The object of the present invention, the frame 10 forming the mold of the heating furnace,

상기 후레임(10)에 베어링(B)으로 회전 자유롭게 축지지되고 선단에 삽입부(32)가 구비되는 회동축(30)과,A rotation shaft 30 rotatably supported by the bearing B on the frame 10 and having an inserting portion 32 at a tip end thereof;

상기 회동축(30)을 구동하는 구동수단(11)과,Drive means 11 for driving the pivot shaft 30;

상기 회동축(30)의 삽입부(32)에 끼워지며 속이 빈 원통형의 로울러(20)로 구성된 것에 있어서,In the hollow shaft roller 20 is fitted to the insertion portion 32 of the rotating shaft 30,

상기 로울러(20)와 회동축(30)의 사이로 코일스프링(40)이 탄력 설치되어 달성된다.The coil spring 40 is elastically installed between the roller 20 and the rotation shaft 30.

따라서, 고온의 열이 지속적으로 전달되는 작업공정에서도 전자부품 등을 이송하는 로울러(20)가 길이방향으로 팽창되어도, 양끝단부에서 코일스프링(40)에 의해 열변형을 흡수하므로, 로울러(20)의 수평상태를 유지시켜 불량률을 감소시키게 된다.Therefore, even when the roller 20 for conveying electronic parts and the like is expanded in the longitudinal direction even in a work process in which high-temperature heat is continuously transmitted, since the coil spring 40 absorbs thermal deformation at both ends, the roller 20 By maintaining the horizontal state of the defect rate is reduced.

또, 로울러를 열변형률이 적은 고가의 재질로 성형하지 않고 열변형률이 높은 재질을 사용하더라도 로울러의 변형을 방지할 수 있어, 제품의 가격 경쟁력 및 생산성을 향상시킬 수 있다.In addition, even if the roller is not formed of an expensive material having a low thermal strain, and a material having a high thermal strain is used, deformation of the roller can be prevented, thereby improving the cost competitiveness and productivity of the product.

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 3은 본 발명인 가열로의 이송로울러 구동장치가 본체에 설치된 상태를 도시한 평단면도이다.Figure 3 is a plan sectional view showing a state in which the transfer roller drive device of the present invention is installed in the main body.

도 4는 본 발명인 가열로의 이송로울러 구동장치인 탄성부재가 설치된 상태를 도시한 부분 확대 단면도이다.4 is a partially enlarged cross-sectional view illustrating a state in which an elastic member, which is a driving roller driving apparatus of the present invention, is installed.

도 3 및 도 4에서 도시한 바와 같이, 원통형의 봉 형상으로 이루어진 소정길이의 로울러(20)의 양단부에는, 후레임(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 cylindrical rod shape, the rotation shaft is connected to the drive means 11, which is hung on the frame 10 and is connected to the chain 30 is inserted and installed.

상기 회동축(30)은 후레임(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 frame 10, and the stepped portion 33 is formed in the inner side, the separation of the rotating shaft 30 Prevented.

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

또한, 회동축(30)은 후레임(10)에 일정간격을 두고 반복적으로 형성되어 있으며, 체인에 의해 모든 회동축(30)이 연결되어 있어, 구동수단(11)의 동력을 전달받을 수 있게 하였다.In addition, the rotation shaft 30 is repeatedly formed at a predetermined interval on the frame 10, all the rotation 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 동일 속도로 회전시킬 수 있도록 하였다.Therefore, the power transmitted through the drive means 11 was able to rotate several rotating shafts 30 at the same speed through the chain and the sprocket at the same time.

그리고, 회동축(30)의 다른 일측으로는 원통형의 로울러(20) 내부로 끼워지는 삽입부(32)가 형성되어 있어, 회동축(30)이 회전하면 축에 고정된 로울러(20)가 같이 회전하는 것이다.On the other side of the rotating shaft 30, an insertion portion 32 is formed to be fitted into the cylindrical roller 20. When the rotating shaft 30 rotates, the roller 20 fixed to the shaft is the same. To rotate.

이때, 회동축(30)의 삽입부(32)에는 코일스프링(40)를 탄력 설치하게 된다.At this time, the coil spring 40 is elastically installed in the insertion portion 32 of the rotation shaft 30.

상기 코일스프링(40)는 로울러(20)의 외면(21)과 회동축(30)의 단턱부(33) 사이에 탄력 설치되는 것에 의해 회동축(30)의 단턱부(33)와 로울러(20)의 외면(21)이 코일스프링(40)을 통해 큰 접촉력을 갖게 되어, 회동축(30)의 회전력을 코일스프링(40)을 통해 로울러(20)에 전달되는 것이다.The coil spring 40 is elastically installed between the outer surface 21 of the roller 20 and the stepped portion 33 of the rotational shaft 30 so that the stepped portion 33 and the roller 20 of the rotational shaft 30 are rotated. The outer surface 21 of) has a large contact force through the coil spring 40, the rotational force of the rotating shaft 30 is transmitted to the roller 20 through the coil spring 40.

따라서, 고온의 열이 로울러(20)에 전달되어 로울러(20)가 길이방향으로 팽창되어도 양측부에서 코일스프링(40)가 열변형량을 흡수하면서도 그 접촉력은 유지 하여 회동축(30)의 회전력을 로울러(20)로 전달될 수 있는 것이다.Therefore, even if the high temperature heat is transmitted to the roller 20 and the roller 20 is expanded in the longitudinal direction, the coil spring 40 absorbs the thermal strain at both sides while maintaining the contact force while maintaining the rotational force of the rotation shaft 30. It can be delivered to the roller (20).

이때, 로울러(20)와 회동축(30)과의 접촉면적을 향상시키기 위해 코일스프링(40)의 양 단부를 축 직각방향으로 가공하여 직각접촉면을 가공하는게 좋다.At this time, in order to improve the contact area between the roller 20 and the rotational shaft 30, it is preferable to process the right angle contact surface by processing both ends of the coil spring 40 in the direction perpendicular to the axis.

즉, 로울러(20)의 외면(21)과 회동축(30)의 단턱부(33)가 평상시에도 코일스프링(40)의 탄성력에 의해 밀착고정되어 회전하며, 고온상태에서도 로울러(20)의 팽창시 코일스프링(40)가 그 변형률을 흡수하며, 외면(21)과 단턱부(33)가 밀착되어 있어, 로울러(20)는 수평상태를 유지하며, 회전이 원활히 이루어지는 것이다.That is, the outer surface 21 of the roller 20 and the stepped portion 33 of the rotation shaft 30 are fixed and rotated by the elastic force of the coil spring 40 even in normal times, and the expansion of the roller 20 even at a high temperature state. When the coil spring 40 absorbs the strain, and the outer surface 21 and the stepped portion 33 are in close contact, the roller 20 maintains a horizontal state, and the rotation is smoothly performed.

상기와 같은 본 발명의 구성에 의하면, 고온의 열이 지속적으로 전달되는 작업공정에서도 전자부품 등을 이송하는 로울러가 길이방향으로 팽창되어도, 양끝단부에서 탄성부재에 의해 열변형량을 흡수하면서도 동력전달이 가능하므로, 로울러의 수평상태를 유지시켜 불량률을 감소시키게 된다.According to the configuration of the present invention as described above, even in a work process in which high-temperature heat is continuously transmitted, even if the roller for transferring the electronic components is expanded in the longitudinal direction, the power transmission is absorbed while absorbing the thermal strain by the elastic member at both ends. Since it is possible to maintain the horizontal state of the roller to reduce the failure rate.

또, 로울러를 열변형률이 적은 고가의 재질로 성형하지 않고 열변형률이 높은 재질을 사용하더라도 로울러의 변형을 방지할 수 있어, 제품의 가격 경쟁력 및 생산성을 향상시킬 수 있는 등의 매우 유용한 발명인 것이다.In addition, even if the roller is not formed of an expensive material having a low thermal strain, and a material having a high thermal strain is used, deformation of the roller can be prevented, thereby improving the price competitiveness and productivity of the product.
