본 고안은 비디오 테이프 권취용 팬케이크 허브에 관한 것으로, 더욱 상세하게는 허브의 중앙부 리브를 개선하여 양질의 팬케이크허브(또는 자기테이프)를 제조할 수 있도록 한 비디오 테이프 권취용 팬케이크 허브에 관한 것이다.The present invention relates to a pancake hub for winding a video tape, and more particularly, to a pancake hub for winding a video tape to improve the center rib of the hub to produce a high quality pancake hub (or magnetic tape).
일반적으로 비디오 카세트용 테이프를 제작함에 있어서, 제1도에 도시한 바와 같이, 먼저 표면에 도료가 코팅된 베이스필름(1)이 킬린더링(calendering) 공정을 거치고, 절단기구부(2)를 통과하는 슬리팅(slitting) 공정을 거쳐 일정폭을 갖는 자기테이프로 슬리팅되며, 슬리팅되어 오는 자기테이프(3)는 비디오카세트용 테이프권취용 팬케이크허브(4)에 권회되어 팬케이크(3)의 형태로 상품화된다.In general, in manufacturing a tape for a video cassette, as shown in FIG. 1, first, the base film 1 coated with a paint is subjected to a calendering process, and then passes through a cutter sphere 2. The slitting magnetic tape 3, which is slitted by a slitting process, has a predetermined width, and the slitting magnetic tape 3 is wound by a tape winding pancake hub 4 for a video cassette, in the form of a pancake 3. It is commercialized.
상기한 바와 같은 비디오카세트용 테이프 제조장치에 사용되는 팬케이크허브(4)는 릴홀더(도시되지 않음)에 장착되어 회전하면서 자기테이프(3)를 권취하는 바, 그 형상을 첨부한 도면에 의하여 설명하면 다음과 같다.The pancake hub 4 used in the video cassette tape manufacturing apparatus as described above is mounted on a reel holder (not shown) to wind the magnetic tape 3 while rotating, and the shape thereof will be described with reference to the accompanying drawings. Is as follows.
종래의 팬케이크허브는 제2도 및 제3도에 도시한 바와 같이, 중앙부에 원통형의 내경을 형성하고, 내주벽(7)과 외주벽(8)을 연결하는 법선부 리브(5)의 폭을 외주표면(9)의 폭과 동일하게 형성하고, 중앙부 리브(5)를 법선부 리브(6)에 십자형으로 교차시킨 형태로 형성한다.In the conventional pancake hub, as shown in FIGS. 2 and 3, a cylindrical inner diameter is formed at the center portion, and the width of the normal rib 5 connecting the inner circumferential wall 7 and the outer circumferential wall 8 is increased. It is formed to be equal to the width of the outer circumferential surface 9, and is formed in the form where the center rib 5 crosses the normal rib 6 in a cross shape.
이와같이 구성된 종래 팬케이크허브(4)는 자기테이프를 권취하여 팬케이크(3)를 형성하게 된다.The conventional pancake hub 4 configured as described above winds up the magnetic tape to form the pancake 3.
그러나, 상기한 바와 같은 종래의 팬케이크허브(4)는 중앙부 리브(5)가 외주표면(7)의 폭과 동일한 폭으로 형성되어 사출성형시 제3도에 도시한 바와 같이, 힘 F가 팬케이크허브(4)의 외주표면(9) 방향으로 집중되어 일점쇄선으로 도시한 바와 같이, 중앙부위가 함몰되고, 이로 인하여 표면조도가 떨어지며, 자기테이프면에 손상을 초래함은 물론, 이러한 자기테이프로 녹화 및 재생할 때 일정간격으로 화면에 잡음이 나타나게 되는 문제점 발생하였다.However, in the conventional pancake hub 4 as described above, the center rib 5 is formed to have the same width as that of the outer circumferential surface 7, and as shown in FIG. 3 at the time of injection molding, the force F is the pancake hub. As shown by the dashed-dotted line concentrated in the direction of the outer circumferential surface 9 of (4), the center portion is recessed, which causes the surface roughness to drop, causing damage to the magnetic tape surface, as well as recording with such magnetic tape. And the problem occurs that the noise appears on the screen at regular intervals during playback.
본 고안은 상기한 바와 같은 종래의 문제점을 감안하여 안출한 것으로서, 본 고안의 목적은 팬케이크의 사출성형시 외주표면으로 작용하는 힘을 제거하여 외주표면의 표면조도를 높여서 자기테이프의 품질저하를 방지할 수 있는 비디오 테이프 권취용 팬케이크 허브를 제공하는데 있다.The present invention was devised in view of the above-described problems, and an object of the present invention is to remove the force acting on the outer circumferential surface during injection molding of pancakes, thereby increasing the surface roughness of the outer circumferential surface to prevent deterioration of magnetic tape. The present invention provides a pancake hub for winding a video tape.
상기 목적을 달성하기 위한 본 고안은 반가공 상태의 비디오카세트용 테이프를 권취하기 위한 권취용 팬케이크허브에 있어서, 중앙부 리브의 폭을 외주표면의 폭보다 작게 성형시킨 비디오 테이프 권취용 팬케이크 허브에 그 특징이 있다.The present invention for achieving the above object is a winding pancake hub for winding a video cassette tape in a semi-processed state, characterized in that the video tape winding pancake hub formed the width of the central rib less than the width of the outer peripheral surface There is this.
이하, 이러한 본 고안은 첨부한 도면의 실시예를 들어 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the embodiments of the accompanying drawings.
제4도는 본 고안에 의한 비디오 테이프 권취용 팬케이크 허브의 구조를 나타낸 것으로, 일정두께를 갖는 내주벽(7)과 외주벽(8)을 형성하고, 양 벽면(7),(8)을 팬케이크허브(4)의 원주방향으로 일정각도 간격으로 법선부 리브(6)를 연결하고, 상기 법선부 리브(6)를 외주표면(9)의 폭보다 축소 성형한 중앙부 리브(10)를 십자형으로 교차 연결한 형태로 형성된다.4 shows the structure of the pancake hub for winding a video tape according to the present invention, and forms an inner circumferential wall 7 and an outer circumferential wall 8 having a predetermined thickness, and both wall surfaces 7 and 8 are pancake hubs. The normal ribs 6 are connected at regular angle intervals in the circumferential direction of (4), and the central ribs 10 formed by reducing the normal ribs 6 to the width of the outer circumferential surface 9 are cross-crossed. It is formed in one form.
상기한 바와 같은 본 고안은 비디오카세트용 테이프 제조장치의 릴홀더(도시되지 않음)에 장착되어 자기테이프를 권취하며, 팬케이크의 사출성형성시 외주표면(제2도의 9)의 폭보다 작게 성형한 중앙부 리브(10)에 의해 외주벽(8)으로 작용하는 힘 F에 대응되는 역방향 힘 F가 작용됨으로써 외주표면(9)을 함몰시키는 힘 F가 상쇄되고, 이에 따라 외주표면(9)의 표면조도가 향상되어 자기테이프면의 손상을 방지하고, 자기테이프의 기록 및 재생시 화면에 잡음이 일정간격으로 나타나는 현상을 방지할 수 있는 효과가 있다.The present invention as described above is mounted on a reel holder (not shown) of a tape cassette manufacturing apparatus for a video cassette and winds up a magnetic tape, and a central portion formed smaller than the width of the outer circumferential surface (9 of FIG. 2) during injection molding of a pancake. The reverse force F corresponding to the force F acting on the outer circumferential wall 8 by the ribs 10 is applied to cancel the force F that dents the outer circumferential surface 9, and thus the surface roughness of the outer circumferential surface 9 is reduced. It is improved to prevent damage to the magnetic tape surface and to prevent the phenomenon of noise appearing on the screen at regular intervals during recording and reproduction of the magnetic tape.
