본 고안은 자기기록테이프 권취용 팬케이크(pan cake)허브에 관한 것으로 보다 구체적으로는 비디오테이프와 같은 자기기록재 제조용 팬케이크를 권취하는데 사용되는 자기기록테이프 권취용 팬케이크허브에 관한 것이다.The present invention relates to a pancake hub for winding magnetic recording tape, and more particularly, to a pancake hub for winding magnetic recording tape used to wind a pancake for manufacturing magnetic recording material such as a video tape.
일반적으로 팬케이크허브에 감긴 테이프를 비디오테이프카세트에 다시 감아주는 리와인더의 경우 팬케이크를 홀딩할 수 있는 규격이 통일되지 않고 크게 나누어 폭이 15.2㎜, 18㎜ 등으로 다양하게 시중에 유통되고 있다.In general, a rewinder that rewinds a tape wound on a pancake hub to a video tape cassette is widely distributed in the market in 15.2 mm and 18 mm widths.
따라서 종래에는 폭이 18㎜인 허브를 홀딩할 수 있는 리와인더에 폭이 15.2㎜인 허브를 장착할 경우 폭차이를 보정하기 위하여 별도의 패드를 사용해야만 하기 때문에 취급이 매우 번거로웠을 뿐 아니라 작업이 능률적이지 못한 문제점이 있었다.Therefore, when a hub with a width of 15.2 mm is mounted on a rewinder that can hold a hub having a width of 18 mm, handling is very cumbersome because a separate pad must be used to compensate for the width difference. There was an inefficient problem.
또 근래에는 비디오테이프 카세트상태에서 녹화하는 방식뿐 아니라 팬케이크에 감겨있는 테이프상태에서 녹화하는 기계가 출현하고 있으며 이와 같은 기계의 경우 팬케이크허브의 홀더규격이 18㎜로 고정되어 있어 폭이 15.2㎜인 팬케이크허브를 홀더에 장착하여 사용하면 한쪽으로 편심되어 주행각도가 기울어지기 때문에 주행성이 좋지 않게 되고 이로 인하여 테이프의 권취상태가 불균일하게 된다.In recent years, not only the recording method in the state of videotape cassette but also the recording in the state of the tape wound on the pancake have appeared. In such a case, the pancake hub holder has a fixed standard of 18mm and the pancake having a width of 15.2mm. When the hub is mounted to the holder and used, the running angle is inclined to one side and the running angle is inclined, resulting in uneven winding of the tape.
그리고 팬케이크 포장시 여러개의 팬케이크를 적층시켰을때 15.2㎜허브와 18㎜ 허브의 부피가 다르므로 포장규겨이 다르고 18㎜허브의 경우 15.2㎜허브의 포장부피보다 크게 되어 포장재제작비용과 운송비용이 많이 드는 등의 문제점이 있었다.In case of pancake packaging, when the pancakes are laminated, the volume of 15.2mm hub and 18mm hub is different, so the packing size is different, and in case of 18mm hub, it is bigger than the packing volume of 15.2mm hub, which makes packing material cost and transportation cost much. There was a problem.
본 고안은 이와 같은 종래의 제반문제점을 해결한 것인 바, 본 고안의 목적은 외주면의 폭이 15.2㎜이면서도 내주면의 폭이 18㎜ 짜리인 허브를 홀딩할 수 있도록 된 리와인더의 홀더에 장착하여 주행하더라도 감겨지거나 풀려지는 상태를 균일하게 유지시켜줄 수 있고, 허브폭을 15.2㎜로 하는 포장규격에 그대로 적용시킬 수 있어 포장 및 운송비용이 증가되지 않는 자기기록테이프 권취용 팬케이크허브를 제공하는데 있다.The present invention solves such a conventional problem, the object of the present invention is that the outer circumference of the 15.2 mm width, while the inner circumference of the 18 mm width of the hub can be held in the holder of the rewinder to run Even if the wound or unwinded state can be maintained uniformly, and the hub width is 15.2mm, it can be applied as it is to provide a pancake hub for winding magnetic recording tape does not increase the packaging and transportation costs.
이하 본 고안을 예시도면에 의하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail by way of example.
본 고안은 제1, 2도에 예시한 바와 같이 폭(d1)이 15.2㎜인 외주면 (1)과, 축공(2)을 제공하는 내주면(3)그리고 내주면(3)에 일정한 간격으로 와인딩머신에 홀딩시 슬립방지용 요입부(4)를 형성한 것에 있어서, 내주면(3)의 폭(d2)을 15.2㎜미만으로 하고, 내주면(3)쪽 요입부(4)주위에 폭(d3)이 18㎜인 돌출부(5)를 일정한 간격으로 형성하며, 외주면(1)으로부터 내주면(3)사이에는 축공(2)을 향하여 하향경사각(θ1)이 6°정도인 경사진 리브(6)를 형성하여서 된 것이다.In the present invention, as illustrated in FIGS. 1 and 2, the winding machine is disposed at regular intervals on the outer circumferential surface 1 having a width d 1 of 15.2 mm, the inner circumferential surface 3 providing the shaft hole 2, and the inner circumferential surface 3. In the case where the slip preventing concave portion 4 is formed at the time of holding on the inner surface, the width d 2 of the inner circumferential surface 3 is less than 15.2 mm, and the width d 3 around the concave portion 4 toward the inner circumferential surface 3 . These 18 mm projecting portions 5 are formed at regular intervals, and between the outer circumferential surface 1 and the inner circumferential surface 3 are inclined ribs 6 having a downward inclination angle θ 1 of about 6 ° toward the shaft hole 2. It was formed.
돌출부(5)의 양끝은 내주면(3)과 경사각(θ2)이 30°정도인 경사면(5')을 이루고 있으며, 본 고안에 있어서 돌출부(5)를 본 고안에 의한 다른 팬케이크허브와 적층시켰을때 외주면(1)의 폭(d1)보다 작은 폭(d2)을 가짐으로 해서 돌출부(5)와 대칭되는 형태의 오목부(7)를 이루는 다른 팬케이크허브의 내주면(3)과 상호 긴밀하게 맞물려지게 되고, 외주면(1)과 내주면(3)사이의 경사진 리브(6)는 본 고안에 의한 팬케이크허브끼리 적층시켰을 때 마주하는 외주면(1)간에 불필요한 공간이 존재하지 않도록 해준다.Both ends of the protruding portion 5 form an inclined surface 5 'with an inner circumferential surface 3 and an inclination angle θ 2 of about 30 degrees. In the present invention, the protruding portion 5 is laminated with another pancake hub according to the present invention. the width of a width (d 2) than that (d 1) of the outer surface (1) having a to projection 5 and the forming the recessed portion 7 of the symmetrical shape closely interact with an inner peripheral surface 3 of the other pancake hub when The inclined ribs 6 between the outer circumferential surface 1 and the inner circumferential surface 3 ensure that there is no unnecessary space between the outer circumferential surfaces 1 facing when the pancake hubs according to the present invention are laminated.
그리고 본 고안에 있어서 폭(d3)이 18㎜인 돌출부(5)를 요입부(4)주위에 형성시킨 이유는 폭이 18㎜짜리인 허브를 홀딩할 수 있도록 된 와인딩머신이나 리와인더의 홀더에 장착하여 주행시켰을 때 주행각도의 기울어짐을 방지하여 주행성을 좋게 하기 위한 것이다.In the present invention, the reason why the protrusion 5 having the width d 3 of 18 mm is formed around the indentation 4 in the holder of the winding machine or the rewinder to hold the hub having the width of 18 mm is provided. It is to improve the driving performance by preventing the inclination of the running angle when the vehicle is mounted and running.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
본 고안은 외주면(1)의 폭(d1)을 15.2㎜로 하고, 내주면(3)의 폭(d2)을 외주면(1)의 폭(d1)미만으로 하여 외주면(1)과 내주면(3)사이에 축공(2)을 향하여 6°정도의 하향경사각(θ1)을 갖는 경사진 리브(6)를 형성함과 아울러 내주면(3)쪽 슬립방지용 요입부(4)주위에는 18㎜의 폭 (d3)을 가진 돌출부(5)를 일정한 간격으로 형성시켜서 된 것이기 때문에 외주면(1)의 폭(d1)이 15.2㎜ 짜리이지만 내주면(3)의 슬립방지용 요입부(4)주위에 폭(d3)이 18㎜인 돌출부(5)가 형성된 것이므로 18㎜짜리 허브를 홀딩할 수 있도록 된 와인딩머신이나 리와인더의 홀더에 장착시켰을 때 안정된 주행성능을 얻을 수 있고, 허부들을 적층시켰을 때 경사진 리브(6)와, 외주면(1)의 폭(d1)미만의 폭(d2)을 갖는 내주면(3)에 의해서 외주면(1)끼리 서로 밀착시켜 줄 수 있으며 돌출부(5)가 이 돌출부(5)와 상대적으로 대칭되는 형태의 오목부(7)를 제공하는 내주면(3)과 상호 긴밀하게 맞물려지게 되는 것이므로 15.2㎜용 포장자재의 규격에 그대로 적용시킬 수 있어 포장 및 운송비용을 증가시키지 않는 장점이 있다.The present invention has a width d 1 of the outer circumferential surface 1 as 15.2 mm, and a width d 2 of the inner circumferential surface 3 as less than a width d 1 of the outer circumferential surface 1, so that the outer circumferential surface 1 and the inner circumferential surface ( 3) inclined ribs 6 having a downward inclination angle θ 1 of about 6 ° toward the shaft hole 2 and between the inner circumferential surface 3 and the slip preventing recesses 4 around 18 mm Since the protrusions 5 having the width d 3 are formed at regular intervals, the width d 1 of the outer circumferential surface 1 is 15.2 mm, but the width around the slip prevention recesses 4 of the inner circumferential surface 3 is wide. Since (d 3 ) has a protrusion 5 of 18 mm, stable running performance can be obtained when it is mounted on a winding machine or a rewinder holder that can hold a hub of 18 mm. The outer circumferential surfaces 1 can be brought into close contact with each other by the ribs 6 and the inner circumferential surface 3 having a width d 2 of less than the width d 1 of the outer circumferential surface 1, and the protrusions 5 are provided. Since it is closely interlocked with the inner circumferential surface 3 that provides the recessed portion 7 which is relatively symmetrical with the protrusion 5, it can be applied directly to the specification of the packaging material for 15.2 mm, thereby increasing the packaging and transportation costs. There is an advantage not to.
