Summary:The present invention relates to a bobbin holder (100), which is arranged at a supply unit of an industrial machine, the material of which is threads, and which holds the bobbin (B) around which threads are wound in a replaceable manner. To this end, the present invention is characterized by comprising: a rotation wheel (10) which is rotated such that the threads wound around the bobbin (B) may be unwound while maintaining a predetermined tension; a rotation pipe (20) which is fixedly mounted on the center of the front surface of the rotation wheel (10), and is inserted into the center on the inside of the bobbin (B) such that the bobbin (B) may be mounted; and a holding means (30) which is arranged at the center on the inside of the rotation pipe (20), and selectively pressurizes the inner surface of the bobbin (B) by a motion of being extended or contracted corresponding to the rotation maneuver. Therefore, according to the present invention, a simple structure is adopted so as to hold the bobbin while being radially extended and contracted by the mutual interference corresponding to the mechanical rotation and the sliding movement, thereby enabling easy and convenient control. Furthermore, the present invention has a reduced failure rate, thereby facilitating ease in maintenance and repair. In addition, the bobbin may be closely held with an excellent concentricity, such that the threads may be smoothly supplied. The present invention can be widely applied regardless of the inner diameters of the bobbin, thereby being utilized for various industrial machines. 본 발명은 원사를 재료로 하는 산업기계의 공급부에 배치되고, 원사가 감긴 보빈(B)을 교체 가능하게 잡아주는 보빈홀더(100)에 관한 것으로, 상기 보빈(B)에 감겨진 원사가 소정의 장력을 유지하며 풀려지게 회전하는 회동휠(10); 상기 회동휠(10)의 전면 중앙에 고정 장착되고, 상기 보빈(B)의 내부 중앙에 삽입되어 보빈(B)을 거치하는 회동관(20); 상기 회동관(20)의 내부 중앙에 배치되고, 회전조작에 따라 벌리거나 오므려지는 작용으로 보빈(B)의 내면을 선택적으로 압박하는 홀딩수단(30);을 포함하여 이루어지는 것을 특징으로 한다. 따라서 본 발명은 기계식 회전과 슬라이드 이동에 따른 상호간의 간섭에 의해 방사형으로 벌리고 오므려져 보빈을 홀딩할 수 있는 단소한 구조를 채택하여 쉽고 편리한 조작이 가능함과 더불어 고장률이 낮아 유지보수가 용이함은 물론 보빈을 긴밀하면서도 우수한 동심도로 홀딩할 수가 있으므로 원사의 원활한 공급을 기대할 수 있을 뿐만 아니라 보빈의 내경에 구애받지 않고 두루 적용이 가능하여 다양한 산업기계에 활용이 가능한 효과가 있다.
