본 고안은 테이프 구동용 핀치로울러에 관한 것으로, 특히 생산성을 향상시키고 원가절감을 도모한 테이프구동용 핀치로울러에 관한것이다.The present invention relates to a tape drive pinch roller, and more particularly, to a tape drive pinch roller that improves productivity and reduces cost.
종래의 브이씨알등의 자기기록재생장치에서 테이프를 구동하기 위한 핀치로울러는 제1도에 도시한 바와 같이 슬리브(2)에 고무롤(1')이 압입되어 있으며, 이 고무롤(1')의 외주면이 만곡면으로 형성되어 있다.In the conventional pinch roller for driving a tape in a magnetic recording / reproducing apparatus such as BC, a rubber roll 1 'is press-fitted into the sleeve 2 as shown in FIG. 1, and the outer circumferential surface of the rubber roll 1'. This curved surface is formed.
그러나 이와 같은 종래의 핀치로울러는 고무롤(1')를 성형하는 과정에서 만곡면을 가지도록 성형연마하는방법을 사용하고 있는바, 이러한 성형연마방법은 단순한 원통연마에 비하여 기술적으로 어려움이 뒤따르며, 설비가 고가로 되고 생산성이 저하되어 원가상승을 초래하게 되는 문제점이 있었다.However, such a conventional pinch roller uses a method of forming and polishing to have a curved surface in the process of forming the rubber roll (1 '), this forming polishing method is technically difficult compared to a simple cylindrical polishing, There is a problem that the equipment is expensive and the productivity is lowered resulting in a cost increase.
또한 종래에는 일본 공개실용신안공보 소 55-11607호 및 소 63-153332호와 같이 림과 원통형 고무롤, 회전체와 원통형 고무롤을 각각 사용한 것이 안출되어 있다.Further, conventionally, rims, cylindrical rubber rolls, rotary bodies and cylindrical rubber rolls, such as Japanese Laid-Open Utility Model Publication Nos. 55-11607 and 63-153332, have been conceived.
그러나 이들은 최종적인 윈통형 고무롤의 최대 직경이 림 또는 회전체에 형성된 만곡면에 의해 결정되는것으로 그 직경을 필요에 따라 가변시킬 수 없어 브이씨알등의 기기에 적용함에 있어서 한계가 있는 것이었다.However, since the maximum diameter of the final wintong rubber roll is determined by the curved surface formed on the rim or the rotating body, the diameter cannot be changed as needed, and thus, there is a limit in applying it to a device such as BC-AL.
또한 이들은 로무롤을 림 또는 회전체에 조립함에 있어 림 또는 회전체의 양측에 형성된 돌기에 의하여 간섭을 받게 되어 조립이 어렵게 되는 문제점이 있었다.In addition, they have a problem that the assembly is difficult to be interfered with the projections formed on both sides of the rim or the rotating body in the assembly of the romur roll on the rim or the rotating body.
본 고안의 목적은 기술적으로 성형이 용이하고 설비가 저렴하며 생산성이 향상되어 원가절감을 기할 수 있도록 한 테이프 구동용 핀치로울러를 제공하려는 것이다.It is an object of the present invention to provide a tape driving pinch roller that is technically easy to mold, inexpensive to install, and improves productivity to reduce cost.
본 고안의 다른 목적은 고무롤의 최대 직경을 필요에 따라 가변시킬 수 있도록 함으로써 브이씨알등에 적용함에 있어 더욱 효과적으로 되도록 하려는 것이다.Another object of the present invention is to be able to vary the maximum diameter of the rubber roll as needed to be more effective in applying to BC.
이러한 본 고안의 목적을 달성하기 위하여 원통축부가 서로 길이방향으로 슬라이딩 가능하게 겨합되며 일단에는 플랜지부가 형성된 내측슬리브와 외측 슬리브 및, 상기 외측 슬리브의 원통축부가 끼워지는 축공을 가지며 양단이 상기 플랜지부에 밀착되는 원통형 고무롤로 구성됨을 특징으로 하는 테이프 구동용 핀치로울러가제공된다.In order to achieve the object of the present invention, the cylindrical shaft parts are slidably joined to each other in the longitudinal direction and have an inner sleeve and an outer sleeve having a flange portion at one end thereof, and shaft holes into which the cylindrical shaft portions of the outer sleeve are fitted, and both ends of the flange portion. A tape driving pinch roller is provided, characterized in that it consists of a cylindrical rubber roll that is in close contact with it.
이하, 본 고안에 의한 테이프 구동용 핀치로울러를 첨부도면에 도시한 실시례에 따라서 상세히 설명한다.Hereinafter, the tape drive pinch roller according to the present invention will be described in detail according to the embodiment shown in the accompanying drawings.
제2도는 본 고안의 가조립 상태를 보인 단면도이고, 제3도는 완전 조립된 상태를 보인 단면도로서, 이에도시한 바와 같이 원통축부(2a,3a)가 서로 길이방향으로 슬라이딩 가능하게 결합되며 일단에는 플랜지부(2b,3b)가 형성된 내측 슬리브(2)와 외측 슬리브(3) 및, 상기 외측 슬리브(3)의 원통축부(3a)가 끼워지는 축공(1a)을 가지며 양단이 상기 플랜지부(2b,3b)에 밀착되는 원통형 고무롤(1)로 구성된다.Figure 2 is a cross-sectional view showing a pre-assembled state of the present invention, Figure 3 is a cross-sectional view showing a fully assembled state, as shown in the cylindrical shaft portion (2a, 3a) is slidably coupled to each other in the longitudinal direction and the plan at one end An inner sleeve 2 and an outer sleeve 3 having branches 2b and 3b formed therein, and shaft holes 1a into which the cylindrical shaft portion 3a of the outer sleeve 3 is fitted, and both ends of the flange portion 2b, It consists of a cylindrical rubber roll 1 in close contact with 3b).
상기 내, 외측 슬리브(2)의 원통축부(2a)의 외경과 외측 슬리브(3)의 원통축부(3a)의 내경간의 공차는 원통축부(2a)가 원통축부(3a)에 끼워질때 슬라이드 피트(Slide Fit)로 되어 서로 슬라이딩 가능하게 결합되도록되어 있다.The tolerance between the outer diameter of the cylindrical shaft portion 2a of the inner and outer sleeves 2 and the inner diameter of the cylindrical shaft portion 3a of the outer sleeve 3 is that when the cylindrical shaft portion 2a is fitted to the cylindrical shaft portion 3a, the slide fit ( Slide Fit) to be slidably coupled to each other.
상기 플랜지부(2b,3b)에는 서로 마주보는 방향으로 결합돌기(2c,3c)가 원통형으로 절곡형성되며, 고무롤(1)의 양단면에는 상기 결합돌기(2c,3c)가 압입되는 결합홈(lb)이 헝성되어 있다.Coupling protrusions 2c and 3c are bent into a cylindrical shape in a direction facing each other in the flanges 2b and 3b, and coupling grooves 2c and 3c are pressed into both end surfaces of the rubber roll 1. lb) are matted.
이와 같이 구성된 본 고안의 핀치로울러는 외측 슬리브(3)의 원통축부(3a)을 고무롤(1)의 일측으로부터 축공(la)에 삽입하고 내축 슬리브(2)의 원통축부(2a)을 원통축부(3a)에 타측으로부터 삽입하여 제2도와 같이내, 외측 슬리브(2,3)의 플랜지부(2b,3b)가 고무롤(1)의 양단면에 밀착되도록 가조립한다. 이때 플랜지부(2b,3b)에 절곡형성된 결합돌기(2c,3c)를 고무롤(1)의 양단면에 형성된 결합홈(1b)에 압입하는 것에 의하여 고무롤(1)과 내, 외측 슬리브(2,3)가 견고하게 결합되도록 한다.In the pinch roller of the present invention configured as described above, the cylindrical shaft portion 3a of the outer sleeve 3 is inserted into the shaft hole la from one side of the rubber roll 1, and the cylindrical shaft portion 2a of the inner shaft sleeve 2 is replaced by the cylindrical shaft portion ( 3a) is inserted from the other side, and as shown in FIG. 2, the flanges 2b and 3b of the outer sleeves 2 and 3 are temporarily assembled so as to be in close contact with both end faces of the rubber roll 1. At this time, the rubber roll 1 and the inner and outer sleeves 2, by pressing the engaging projections (2c, 3c) formed in the flanges (2b, 3b) into the coupling groove (1b) formed on both ends of the rubber roll (1) 3) should be firmly combined.
제2도와 같이 가조립된 상태에서 브이씨알등의 자기기록재생장치에 장착함에 있어서 기기의 베이스에 고정되는 축(도시되지 않음)을 내측 슬리브(2)의 원통축부(2a)을 통하여 관통시킨 다음 그 축에 체결되는 나사(도시되지 않음)등으로 조이면, 제3도에 도시한 바와 같이 내, 외측 슬리브(2,3)의 조립 길이가 짧아지면서 양측플랜지부(2b,3b)가 고무롤(1)의 양단부를 누르게 되어 고무롤(1)이 길이는 짧아지면서 외경이 확대되며, 이에따라 고무롤(1)의 외주면은 그 길이의 중간부에서 최대직경으로 되며 양단부에서는 최초의 상태와 거의 대등한직경으로 되어 결과적으로 만곡형 외주면을 가지게 된다.In the assembled state as shown in FIG. 2, a shaft (not shown) fixed to the base of the apparatus is passed through the cylindrical shaft portion 2a of the inner sleeve 2 in mounting to a magnetic recording / reproducing apparatus such as BC. When tightened with a screw (not shown) fastened to the shaft or the like, as shown in FIG. 3, the inner and outer sleeves 2 and 3 have a shorter assembly length, so that both flange portions 2b and 3b have a rubber roll 1. The outer diameter of the rubber roll 1 is enlarged as the length of the rubber roll 1 is shortened by pressing both ends thereof. Accordingly, the outer circumferential surface of the rubber roll 1 becomes the maximum diameter at the middle of the length and is almost the same diameter as the original state at both ends. It has a curved outer circumferential surface.
이상과 같이 본 고안에 의하면 원통형 고무롤을 내, 외부 슬리브사이에 결합하여 그 길이를 단축시키는 방향으로 누르는 것에 의하여 외주면의 중간부 직경이 최대로 확대되면서 만곡형으로 형성되도록 하는 것으로서 핀치로울러로서의 기능을 충분히 발휘할 수 있음과 아울러 고무롤을 제작할 때 기술적으로 어렵고 설비가 고가인 성형연마방법을 사용하지 않고 기술적으로 용이하며 설비가 저렴한 원통연마방법으로 제작할 수 있으므로 생산성이 향상되고 원가절감을 기할 수 있게 되는 효과가 있는 것이다. 또한 고무롤과 내,외측 슬리브를 조립함에 있어서 간섭을 일으키는 일이 없어 조립이 더욱 간편하게 됨과 아울러 고무롤과 내, 외측 슬리브를 조립한상태에서 슬리브의 결합길이를 가변시키는 것에 의해 고무롤의 최대 직경을 필요에 따라 가변시킬 수 있어브이씨발등의 기기에 적용함에 있어 더욱 효과적으르 되는 것이다.According to the present invention as described above, by pressing the cylindrical rubber roll between the inner and outer sleeves and pressing in the direction of shortening the length thereof, the middle portion of the outer circumferential surface is formed to be curved while being enlarged to the maximum, thereby functioning as a pinch roller. In addition, it is possible to achieve sufficient performance, and it is possible to manufacture by using the cylindrical polishing method which is technically difficult and inexpensive without the use of the molding polishing method which is technically difficult and expensive when manufacturing the rubber roll, and thus the productivity is improved and the cost reduction can be achieved. There is. In addition, the assembly of the rubber roll and the inner and outer sleeves does not cause any interference, which simplifies the assembly and by varying the coupling length of the sleeve in the state where the rubber roll and the inner and outer sleeves are assembled, the maximum diameter of the rubber roll can be adjusted as needed. Because it can be changed, it becomes more effective when applied to devices such as V-Call.
