테이프 레코더의 핀치롤러{A pinch roller of a tape recorder}A pinch roller of a tape recorder

본 고안은 테이프 레코더, 캠코더, 디지탈 오디오 테이프 레코더등에 설치되어 테이프를 정속으로 이송시키는 핀치롤러에 관한 것으로, 특히 핀치롤러의 주요부에 해당하는 슬리브, 회전부재를 열경화성수지를 이용하여 일체로 사출 성형하므로서, 부품수를 줄여 생산원가를 절감하는 동시에 조립을 간편화하여 생산성이 크게 향상될 수 있도록 한 테이프 레코더의 핀치롤러에 관한 것이다.The present invention relates to a pinch roller which is installed in a tape recorder, a camcorder, a digital audio tape recorder, and the like to transfer a tape at a constant speed. In particular, the sleeve and the rotating member corresponding to the main part of the pinch roller are integrally injection molded using a thermosetting resin. In addition, the present invention relates to a pinch roller of a tape recorder that reduces productivity by reducing the number of parts and at the same time simplifies assembly.

일반적으로 비디오 테이프 레코더, 캠코더, 디지탈 오디오 레코더등의 데크 메카니즘은 도1에서와 같이 데크새시(10)에 설치된 공급릴(1)로 부터 권취릴(2)에 감겨진 자기기록 테이프(T)는 다수의 안내롤러 및 가이드 포스트에 의해 소거헤드(3) 및 드럼헤드(4) 그리고 음성헤드(5)를 거쳐 캡스턴 축(6)과 핀치롤러(7)에 의해 일정한 장력으로 권취릴(2)측으로 주행할 수 있도록 구성 되어 있다.In general, deck mechanisms such as a video tape recorder, a camcorder, and a digital audio recorder include a magnetic recording tape (T) wound on a winding reel (2) from a supply reel (1) installed on the deck chassis (10) as shown in FIG. A plurality of guide rollers and guide posts pass through the erasing head 3, the drum head 4, and the sound head 5 to the winding reel 2 with constant tension by the capstan shaft 6 and the pinch roller 7. It is configured to run.

이와 같이 구성된 종래 테이프 레코더는 공급릴(1)로 부터 권취릴(2)측으로 주행하는 테이프(T)는 항상 일정속도를 유지하면서 주행해야 하는데 이는 모터에 의해 회전하는 캡스턴 축(6)과, 이 캡스턴 축(6)에 테이프(T)를 개재한채 압착되는 핀치롤러(7)에 의해 이루어진다.In the conventional tape recorder configured as described above, the tape (T) traveling from the supply reel (1) to the take-up reel (2) should always run while maintaining a constant speed, which is a capstan shaft (6) rotated by a motor, It is made by the pinch roller 7 which is crimped | bonded with the tape T on the capstan shaft 6.

상기와 같은 목적을 가지고 공회전하는 핀치롤러(7)는 도2에서와 같이 슬리브(8)를 중심으로 외부에는 원통형의 고무(9)가 형성되어 있고 내부에는 샤프트(11)를 중심으로 핀치롤러(7)가 공회전되게 하는 회전부재(12)가 연결 형성되어 있다. 여기서 회전부재(12)는 볼베어링 또는 가이드부쉬가 선택적으로 사용된다.The pinch roller 7 idling with the above purpose is formed with a cylindrical rubber 9 on the outside of the sleeve 8 as shown in FIG. 2 and a pinch roller around the shaft 11 on the inside. Rotating member 12 is formed so that 7) is idle. The rotating member 12 is a ball bearing or a guide bush is selectively used.

이와 같이 구성된 종래 핀치롤러(7)를 이용하여 테이프(T)를 안전하게 주행시킬수 있다는 잇점은 있으나, 핀치롤러(7)를 구성하기 위하여 슬리브(8), 회전부재(12)로 나뉘어진 각각의 부품이 요구되기 때문에 부품수가 증가하여 생산원가가 상승될뿐 아니라 조립시 생산성이 크게 저하되는 제반 문제점이 발생되었다.Although there is an advantage in that the tape T can be safely driven using the conventional pinch roller 7 configured as described above, each component divided into the sleeve 8 and the rotating member 12 to constitute the pinch roller 7. Due to this demand, the number of parts increases, not only increases the production cost but also causes various problems in that the productivity during assembly is greatly reduced.

따라서 본 고안의 목적은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로, 핀치롤러의 주요부에 해당하는 슬리브, 회전부재를 열경화성수지를 이용하여 일체로 사출 성형하므로서, 부품수를 줄여 생산원가를 절감하는 동시에 조립을 간편화하여 생산성이 크게 향상될 수 있도록 한 테이프 레코더의 핀치롤러를 제공하는데 있다.Therefore, the object of the present invention was devised in view of the conventional problems as described above, and by integrally injection molding the sleeve and the rotating member corresponding to the main part of the pinch roller using a thermosetting resin, the number of parts is reduced to reduce the production cost. At the same time, to provide a pinch roller of a tape recorder to simplify the assembly and significantly improve the productivity.

상기와 같은 목적을 달성하기 위한 수단으로 본 고안은, 핀치롤러를 구성하는 슬리브와 회전부재는 내구성과 내마모성이 요구되는 몰리브덴, 멜라닌, 그라파이터, 페놀수지등과 같은 열경화성수지에 의해 일체로 사출 성형되는 것을 그 기술적 구성상의 기본 특징으로 한다.As a means for achieving the above object, the present invention, the sleeve and the rotating member constituting the pinch roller is integrally injection-molded by thermosetting resins such as molybdenum, melanin, graphite, phenol resin, etc. requiring durability and wear resistance It is to be the basic characteristic in the technical constitution.

이하 본 고안의 바람직한 실시예를 첨부도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도3은 본 고안에 따른 핀치롤러의 단면도로서, 핀치롤러(100)를 구성하는 슬리브(210)와 회전부재(220)는 열경화성수지(200)에 의해 일체로 사출 성형되는데, 이때의 열경화성수지(200)는 샤프트(11)를 중심으로 회전시 접촉에 의한 마모와 마찰열과 마찰에 의한 소음발생을 방지하기 위한 수단으로 내구성과 내마모성이 요구된다.따라서, 내구성과 내마모성이 뛰어난 열경화성수지(200)로는 몰리브덴, 멜라닌, 그라파이터, 페놀수지 등을 들 수 있으며, 이러한 몰리브덴, 멜라니, 그라파이터, 페놀수지 등은 사출 성형시 하나만 선택되어 열경화성수지(200)로 사용됨을 밝혀 두며, 본 고안의 실시예에서는 몰리브덴이 열경화성수지(200)로 사용되었다.Figure 3 is a cross-sectional view of the pinch roller according to the present invention, the sleeve 210 and the rotating member 220 constituting the pinch roller 100 is integrally injection molded by the thermosetting resin 200, the thermosetting resin ( 200 is a means for preventing the wear caused by contact and the noise generated by frictional heat and friction during rotation around the shaft 11 is required. Durability and abrasion resistance is therefore required. Molybdenum, melanin, graphite, phenolic resin, and the like, such as molybdenum, melanin, graphite, phenolic resin is selected only in the injection molding is used as the thermosetting resin 200, in the embodiment of the present invention Molybdenum was used as the thermosetting resin (200).

상기와 같이 핀치롤러(200)를 구성하는 슬리브(210)와 회전부재(220)의 역활을 동시에 수행할 수 있도록 열경화성수지(200)를 프레스(도시하지 않음)로 사출 성형하면 각각의 열경화성수지(200)에 각기 다른 기능을 갖는 슬리브(210)와 회전부재(220)가 자체에 일체로 형성된다. 이와 같이 구성된 본 고안의 열경화성고무(200)를 사용하기 위해서는 먼저 통상의 결합 방법을 통하여 슬리브(210) 외주면에 고무(9)를 일체로 결합한 후, 도3에서와 같이 샤프트(11)에 열경화성고무(200)를 삽입하면 이 샤프트(11) 외경에는 회전부재(220)의 내경이 접촉된 상태가 된다.상기와 같은 상태에서 테이프가 주행하면 핀치롤러(100)는 샤프트(11)를 중심으로 회전하게 되는데, 이때의 샤프트(11)와 열경화성고무(200)의 접촉면적은 열경화성고무(200) 내부 원주면의 투명면적에 대해 30~80%의 범위로 설정되어 있고, 자체적으로 탄성력을 갖으면서 제조시 내마모성과 내구성이 부여되어 있기 때문에 회전시 회전부재(220)는 샤프트(11)의 접촉에 의한 마모가 방지됨은 물론 마찰열과 마찰에 의한 변형 및 소음은 발생하지 않으면서 회전하게 된다.As described above, when the thermosetting resin 200 is injection-molded by a press (not shown) to simultaneously perform the role of the sleeve 210 and the rotating member 220 constituting the pinch roller 200, each thermosetting resin ( The sleeve 210 and the rotating member 220 having different functions in the 200 are integrally formed therein. In order to use the thermosetting rubber 200 of the present invention configured as described above, the rubber 9 is integrally coupled to the outer circumferential surface of the sleeve 210 through a conventional coupling method, and then the thermosetting rubber is attached to the shaft 11 as shown in FIG. 3. When the 200 is inserted, the inner diameter of the rotating member 220 is in contact with the outer diameter of the shaft 11. When the tape travels in the above state, the pinch roller 100 rotates about the shaft 11. At this time, the contact area of the shaft 11 and the thermosetting rubber 200 is set in the range of 30 to 80% with respect to the transparent area of the inner circumferential surface of the thermosetting rubber 200, and manufactured while having its own elastic force Since wear resistance and durability are given at the time of rotation, the rotating member 220 is rotated while preventing the wear due to the contact of the shaft 11 as well as deformation and noise caused by frictional heat and friction.

이러한 슬리브(210)와 회전부재(220)를 갖는 열경화성수지(200)를 핀치롤러(100)에 장치하면 종래와 같은 기능을 가지고 작동된다.When the thermosetting resin 200 having the sleeve 210 and the rotating member 220 is mounted on the pinch roller 100, the thermosetting resin 200 has the same function as the conventional operation.

이상에서 살펴본 바와 같이 본 고안에 의하면, 핀치롤러의 주요부에 해당하는 슬리브, 회전부재를 열경화성수지를 이용하여 일체로 사출 성형하므로서, 부품수를 줄여 생산원가를 절감하는 동시에 조립을 간편화하여 생산성이 크게 향상될 수 있는 등의 효과가 있는 것이다.As described above, according to the present invention, the sleeve and the rotating member corresponding to the main portion of the pinch roller are integrally injection-molded by using a thermosetting resin, thereby reducing the number of parts and reducing the production cost and simplifying the assembly, thereby greatly increasing productivity. There is an effect such as can be improved.

이상에서는 본 고안을 특정의 바람직한 실시예를 참고하여 설명하였으나, 본 고안은 상기한 실시예에 한정되지 아니하며 본 고안의 요지를 벗어나지 않는 범위에서 통상의 지식을 가진자에 의해 다양한 변경과 수정이 이루어질 수 있는 것임을 밝혀둔다.In the above described the present invention with reference to a specific preferred embodiment, the present invention is not limited to the above embodiments and various changes and modifications made by those skilled in the art without departing from the spirit of the present invention Make sure you can.
