미싱용 북실 권취기의 보빈클램핑구조Bobbin clamping structure of bobbin winder for sewing machine

본 고안은 큰 원사실꾸리로 부터 북실용 보빈에 북실을 권취하도록 하는 미싱용 북실권취기에 관한 것으로, 특히 상기 북실용 보빈이 설치되는 회전축상에 탄지스프링을 설치구성하여 그 탄발력으로 북실용 보빈을 설치하게 되어 보빈 설치에 따른 견고성이 제공하는 미싱용 북실 권취기의 보빈클램핑 구조에 관한 것이다.The present invention relates to a sewing machine bobbin winder for winding the bobbin thread to the bobbin bobbin from a large yarn yarn, and in particular, the bobbin spring bobbin is installed on the rotating shaft on which the bobbin bobbin is installed. It relates to the bobbin clamping structure of the bobbin winder for the sewing machine to provide the firmness according to the installation of the bobbin.

일반적으로 큰 원사실꾸리로 부터 북실용 보빈에 북실을 권취하는 북실권취기를 도1 및 도2를 참조하여 살펴보면, 미싱의 몸체(2)상에서 스프링에 의해 탄발적으로 회동작동하는 축발이(4)의 축지지관(5)에 회전축(10)이 삽입설치되되 상기 회전축(10)의 일측에는 미싱구동모터에 연계구동되는 회전풀리(8)가 고정설치되고 타측에는 길이방향으로 절결홈(11)을 갖는 탄발지지부(12)를 형성하여 이에 북실용보빈(9)을 탄발설치하게 된다.In general, referring to Figure 1 and Figure 2, the bobbin winder winding the bobbin thread in the bobbin for bobbin from a large yarn yarn, the spun shaft (4) that is elastically rotated by the spring on the body (2) of the sewing machine The rotary shaft 10 is inserted into the shaft support tube 5 of the rotary shaft 10, and one side of the rotary shaft 10 is fixed to the rotary pulley 8 which is driven and driven by the sewing machine driving motor, and the other side has a notch groove 11 in the longitudinal direction. By forming a ball support portion 12 having a ball bobbin bobbin 9 is installed thereon.

이때, 상기 북실용보빈(9)이 설치되는 위치의 일측에는 선단에 지지탄지편(7a)이 설치되는 지지수단(7)이 구비되어 상기 지지수단(7)을 눌러 작동시키는 것에 의해 지지탄지편(7a)이 북실용보빈(9)에 권취되는 북실(T)을 탄발적으로 지지하게 된다.At this time, one side of the position where the north bobbin bobbin 9 is installed is provided with a support means (7) is provided with a support support piece (7a) at the front end by supporting the support means by pressing the support means (7) (7a) elastically supports the north room T wound around the north room bobbin 9.

따라서 큰 원사실꾸리로 부터 몸체(2) 일측의 안내홈(3)에 안내되는 상태로 북실(T)이 안내되게 하여 그 끝단을 상기 북실용보빈(9)상에 위치시키되 지지수단(7)의 지지탄지편(7a)에 탄발지지된 상태로 하여 미싱구동모터의 연계구동으로 회전풀리(8)와 회전축(10)을 회전시켜 북실용보빈(9)상에 북실(T)을 권취하게 되는 것이다.Therefore, the north thread (T) is guided in a state of being guided to the guide groove (3) on one side of the body (2) from a large yarn yarn, and its end is positioned on the bobbin bobbin (9), but the support means (7) The rotary pulley 8 and the rotating shaft 10 are rotated by the coupling drive of the sewing machine driving motor in a state in which the support carbon piece 7a is elastically supported to wind the drum T on the bobbin bobbin 9. will be.

그러나 이러한 종래기술에서 상기 북실용보빈(9)이 탄발설치되는 회전축(10)의 탄발지지부(12)는 사용에 따라 절결홈(11)이 좁혀지면서 그 탄발력이 약해져 북실용보빈(9)을 견고하게 설치하기 곤란하게 됨음 물론 이에 따라 북실용보빈(9)과의 사이에 유격이 생겨 축회전시 떨림이 발생되는 문제를 갖게 된다.However, in the prior art, the carbon support portion 12 of the rotary shaft 10 in which the bobbin bobbin 9 is installed in a shot state is narrowed in the notch groove 11 according to the use thereof, so that the resilience is weakened. It is difficult to install firmly, of course, there is a gap between the bobbin bobbin (9) and thus there is a problem that the shaking occurs during the rotation of the shaft.

이때 상기 문제점을 해결하고자 절결홈(11) 부분을 벌리게 되면 이 부분에 비틀림이 발생하게 되어 그 사용이 곤란하게 된다.At this time, if the notch groove 11 is opened to solve the problem, the torsion occurs in this portion, and its use is difficult.

결국, 이러한 종래의 회전축(10)은 상술한 이유로 인해 사용에 따라 자주 교체해주어야 하는 경제성 및 작업성면에서의 문제를 갖게 된다.As a result, the conventional rotary shaft 10 has a problem in terms of economics and workability that must be frequently replaced according to the use for the reasons described above.

더우기 상기한 회전축(10)은 고속회전시 북실용보빈(9)과 면접촉으로 결합되었기 때문에 접촉부분이 마찰에 의해 늘어붙게 되거나 회전축(10)의 마모로 인해 북실보빈(9)이 견고하게 설치되지 못한 관계로 이탈우려가 있어 저속회전으로만의 사용이 가능하게 그 사용상의 제한을 받게 되는 문제 또한 갖게 된다.In addition, since the rotary shaft 10 is coupled to the bobbin bobbin 9 in high-speed rotation by surface contact, the contact parts are lined up by friction or the bobbin bobbin 9 is firmly installed due to the abrasion of the rotary shaft 10. There is also a problem that the use of the low-speed rotation is limited because the use is not possible because of the lack of concern.

본 고안은 상기한 종래기술이 갖는 제반문제점을 해소하고자 안출된 것으로 회전축 선단에 절결부를 형성하고 이 절결부에 탄성력을 갖도록 절곡성형된 탄발스프링을 돌출되게 설치하여서 상기 돌출된 상태의 탄발스프링에 의해 북실보빈을 탄발적으로 조립설치하게 되므로 견고한 조립상태를 유지하게 되어 작업성이 우수하게 됨은 물론 이에 따라 축회전시의 떨림방지, 회전축과 보빈과의 접촉에 따른 마찰로 인한 마모방지로 그 견고성이 우수하게 되는 미싱용 북실권취기의 보빈클램핑구조를 제공하는데 그 목적이 있다.The present invention has been made to solve the problems of the prior art described above to form a cutout at the tip of the rotating shaft and to install a bent molded spring to protrude elastically in the cutout to the protruding tanbal spring By installing the bobbin bobbin elastically, it maintains a solid assembly state, so it is excellent in workability, and accordingly, its robustness is prevented by the vibration during the shaft rotation and the abrasion due to the friction caused by the contact between the rotary shaft and the bobbin. An object of the present invention is to provide a bobbin clamping structure of a sewing machine winding machine winder, which becomes excellent.

미설명부호로서 13은 회전축(10)의 지지단턱을 나타내는 것이다.Reference numeral 13 denotes a support step of the rotating shaft 10.

다음은 상기한 본 고안의 작용에 대해 상세히 살펴보기로 한다.Next will be described in detail with respect to the operation of the present invention described above.

먼저 본 고안은 도5에 도시된 바와같이 회전축(10)상에 북실용보빈(9)을 설치하기 위해서 회전축(10)의 선단절결부(15)에 탄발스프링(20)을 삽입설치하게 되는데 이는 상기 절결부(15) 내측에 형성된 지지홈(17)에 탄발스프링(20)의 절곡지지단(27)을 삽입한 상태로 상기 절결부(15)에 탄성력을 갖도록 절곡된 탄성절곡부(25)를 삽입하여 설치하게 된다.First of all, the present invention inserts and installs a carbon spring 20 into the tip notch 15 of the rotary shaft 10 to install the bobbin bobbin 9 on the rotary shaft 10, as shown in FIG. The elastic bending portion 25 bent to have elastic force in the bending portion 15 in a state in which the bending support end 27 of the carbon spring 20 is inserted into the support groove 17 formed inside the cutting portion 15. To install it.

이때, 상기 탄발스프링(20)의 탄성절곡부(25)는 회전축(10)의 절결부(15)상에서 돌출되게 설치되어 이에 북실용보빈(9)을 탄발적으로 하여 견고하게 설치하게 되고 상기 탄발스프링(20)은 열처리강재로 제작하여 그 견고성이 우수하게 된다.At this time, the elastic bending portion 25 of the carbon spring (20) is installed to protrude on the cutout portion 15 of the rotary shaft 10 to be installed firmly to the bobbin bobbin (9) to this firmly and the bullet The spring 20 is made of a heat-treated steel to be excellent in firmness.

이와같이 회전축(10)상에 북실용보빈(9)을 설치한 상태에서 미싱구동모터에 의한 연계구동으로 회동풀리(8)를 회전시키고 이에 의해 회전축(10)과 북실용보빈(9)을 회전시키면서 상기 북실용보빈(9)에 큰 원사실꾸리로 부터 공급받는 북실은 권취하게 되는 것이다.(도1 참조)In this way, while the bobbin bobbin 9 is installed on the rotary shaft 10, the pivoting pulley 8 is rotated by the linkage drive by the sewing machine driving motor, thereby rotating the rotary shaft 10 and the bobbin bobbin 9. The bobbin thread supplied from the large yarn yarn to the bobbin bobbin 9 will be wound up (see Fig. 1).

이상에서 살펴본 바와같이 본 고안 미싱용 북실권취기의 보빈클램핑구조는 회전축 선단의 절결부에 탄성력을 갖도록 절곡성형된 탄발스프링을 돌출되도록 삽입설치하여 이에 북실보빈을 탄발적으로 조립설치하게 되므로 보빈의 견고한 조립상태를 유지하게 되어 북실권취작업이 우수하게 됨은 물론 이에 의해 상기 회전축과 보빈과의 유격으로 인한 회전시의 떨림이 발생되는 것을 방지하게 되고, 보빈과 상기 회전축과의 면접촉으로 인한 표면마찰로 마모가 발생되는 것을 방지하게 되며 사용에 따라 상기 탄발스프링만을 교체사용하면 되므로 작업성, 견고성 등이 우수한 효과를 갖게 되는 것이다.As described above, the bobbin clamping structure of the bobbin winder for a sewing machine of the present invention is installed so that the bobbin spring is bent to have elastic force at the cutout portion of the rotary shaft so that the bobbin bobbin is elastically assembled and installed. Maintaining a solid assembly state, the bobbin winding work is excellent, thereby preventing the shaking during rotation due to the play between the rotating shaft and the bobbin, and the surface friction due to the surface contact between the bobbin and the rotating shaft. It is to prevent the wear of the furnace to be used, and the use of only the carbon ball spring to replace the use, it will have an excellent effect such as workability, firmness.
