Description

연사용 보빈 {Twisting Bobbins}Speaker Bobbins {Twisting Bobbins}

본 발명은 연사용 보빈에 관한 것으로 보다 구체적으로는 보빈몸통과 플랜지의 결합부 사이로 실이 끼어서 손상되는 것을 방지할 수 있도록 한 연사용 보빈에 관한 것이다.
The present invention relates to a continuous bobbin, and more particularly to a continuous bobbin which can prevent the thread from being damaged between the bobbin body and the engaging portion of the flange.

일반적으로 사용되는 연사용 보빈은 알루미늄재로 된 몸통의 양단부에 합성수지재로 된 원판형의 플랜지를 나사 결합한 구조로 이루어져 있다.Commonly used twist bobbins consist of a screw-shaped flange of a disk-shaped flange made of synthetic resin at both ends of an aluminum body.

이러한 종래의 연사용 보빈은 몸통 부분에 실을 감는 과정에서 압력을 받게 되고, 그러한 과정에서 몸통과 플랜지가 나사 결합되어 서로 접촉하는 몸통의 외측 단부와, 플랜지의 내측면 사이 틈으로 실이 끼어서 손상되거나 끊어지는 경우가 빈번한 문제점이 있었다.This conventional twisted bobbin is subjected to pressure in the process of winding the thread on the body portion, during which the body and the flange is screwed into contact with each other, the thread between the outer end of the body and the gap between the inner surface of the flange is damaged There was a frequent problem of being broken or broken.

또한, 연사 과정에서 보빈이 스핀들에 의해 고속 회전할 때 마모를 최소화하기 위하여 스핀들이 끼워지는 스핀들홀더는 내마모성이 매우 강한 베이클라이트(Bakelite)와 같은 열경화성 합성수지재를 사용하게 되는데 종래의 연사용 보빈은 상기 스핀들홀더의 외주면에 수나사부를 형성하여 이 스핀들홀더를 보빈몸통의 내부에 나사 결합하여 사용하였다.In addition, the spindle holder in which the spindle is fitted to minimize wear when the bobbin rotates at a high speed by the spindle during the twisting process uses a thermosetting synthetic resin material such as Bakelite, which is highly wear resistant. A male thread was formed on the outer circumferential surface of the spindle holder, and the spindle holder was screwed into the bobbin body.

그러나, 베이클라이트는 내마모성은 강한 반면에 금속과 대비할 때 강도는 떨어지기 때문에 연사용 보빈을 사용하는 과정에서 떨어뜨리거나 외부 물체와 부딪히는 등의 충격이 가해질 경우에 스핀들홀더가 파손되거나 스핀들홀더의 수나사부가 손상되어 보빈몸통과의 나사 결합이 불안정해지는 문제점이 있었다.
However, because Bakelite has high abrasion resistance and low strength in comparison with metal, the spindle holder is broken or the spindle holder's male thread is damaged when it is dropped or hit with an external object during the use of a soft bobbin. There was a problem that the screw is unstable to the bobbin body damaged.

본 발명은 위와 같은 종래의 문제점을 해소하기 위하여 안출한 것으로서, 본 발명의 목적은 나사 결합되는 보빈몸통과 플랜지의 결합부 사이로 실이 끼어서 손상되는 것을 방지할 수 있도록 함과 동시에 외부 충격으로부터 스핀들홀더를 효과적으로 보호할 수 있는 연사용 보빈을 제공하는 데 있다.
The present invention has been made in order to solve the above conventional problems, the object of the present invention is to prevent the damage between the threaded bobbin body and the coupling portion of the flange threaded and the spindle holder from the external impact at the same time To provide a continuous bobbin that can effectively protect the

이하, 본 발명을 첨부된 도면에 의하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

첨부된 도면들 중에서 동일한 구성 요소들은 가능한 어느 도면에서든지 동일한 부호를 사용하고 있음을 유의해야 하며, 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 또는 공지 구성에 대한 상세한 설명은 생략하였음을 미리 밝혀두는 바이다.
It is to be noted that like elements in the accompanying drawings use the same reference numerals in any of the drawings, and detailed descriptions of well-known functions or known configurations that may unnecessarily obscure the gist of the present invention are omitted. Come on.

첨부도면 도 1 내지 도 3에서 도시한 바와 같이 본 발명은 양단부 내측에는 각각 암나사부(101)를 형성한 보빈몸통(1)과, 상기 보빈몸통(1)의 양단부에 설치되는 플랜지(2)와, 상기 플랜지(2)를 끼운 상태에서 상기 보빈몸통(1)의 암나사부(101)에 나사 결합되는 홀더고정구(4)와, 상기 홀더고정구(4) 내부에 고정되는 스핀들홀더(3)로 구성되는데 각 구성요소의 구조적 특징과 작용을 보다 상세히 설명하면 다음과 같다.
As shown in FIGS. 1 to 3, the present invention includes a bobbin body 1 having female threads 101 formed at both ends, and a flange 2 installed at both ends of the bobbin body 1. , A holder fixture 4 screwed to the female threaded portion 101 of the bobbin body 1 with the flange 2 fitted therein, and a spindle holder 3 fixed inside the holder fixture 4. The structural features and operations of each component will be described in more detail as follows.

본 발명의 보빈몸통(1)은 알루미늄재 관으로 형성되며, 양단부 내측에는 암나사부(101)를 각각 형성하게 된다.
The bobbin body 1 of the present invention is formed of an aluminum tube, and both ends of the bobbin body 1 to form female threads 101, respectively.

본 발명의 플랜지(2)는 베이클라이트와 같은 열경화성수지를 이용해 원판형으로 형성되며, 그 중심부에는 결합공(202)을 형성하되, 보빈몸통(1)과 접하는 플랜지(2)의 내측면에는 소정 깊이의 요입홈(201)을 형성함으로써 보빈몸통(1)과 플랜지(2)가 결합할 때 보빈몸통(1)의 단부가 플랜지(2)의 요입홈(201) 내부에 삽입된 상태로 결합이 이루어지게 된다.Flange (2) of the present invention is formed in a disk shape using a thermosetting resin such as bakelite, the coupling hole 202 is formed in the center thereof, a predetermined depth on the inner surface of the flange (2) in contact with the bobbin body (1) When the bobbin body 1 and the flange 2 are coupled by forming the recessed groove 201 of the bobbin body 1, the end of the bobbin body 1 is inserted into the recessed groove 201 of the flange 2. You lose.

따라서 보빈몸통(1)에 실을 감을 때 실에 의한 압력이 플랜지(2)를 바깥쪽 방향으로 밀어내더라도 보빈몸통(1)과 플랜지(2)가 접하는 첨부도면 도 3의 ⓐ 지점에 틈이 발생하는 것을 방지함으로써 틈이 발생함에 따른 실의 손상이나 끊어짐을 미연에 방지할 수 있게 된다.
Therefore, when the thread is wound on the bobbin body 1, even if the pressure by the thread pushes the flange 2 outward, a gap occurs at the point ⓐ in FIG. 3 where the bobbin body 1 and the flange 2 are in contact. By preventing the damage, it is possible to prevent damage or breakage of the seal due to the occurrence of a gap.

본 발명의 스핀들홀더(3)는 내마모성이 우수한 베이클라이트와 같은 열경화성 합성수지재로 형성하되, 금속제로 된 홀더고정구(4)의 중심공(401)에 삽설하여 접착 고정하게 된다.The spindle holder 3 of the present invention is formed of a thermosetting synthetic resin material such as bakelite having excellent wear resistance, and is inserted into and fixed to the center hole 401 of the holder fixture 4 made of metal.

이때, 상기 중심공(401)의 내주면에는 결합돌부(404)를 방사형으로 형성함으로써 중심공(401)에 삽설되는 스핀들홀더(3)의 외주면과, 중심공(401) 내주면과의 마찰력을 극대화함과 동시에 접착제를 이용하여 접착 고정할 때 접착제가 스핀들홀더(3)의 외주면과 중심공(401) 내주면 사이에서 균일하게 도포 됨으로써 더욱 견고한 접착 고정이 이루어지게 된다.At this time, the inner circumferential surface of the center hole 401 by radially forming the engaging protrusion 404 to maximize the friction between the outer circumferential surface of the spindle holder (3) inserted into the center hole 401, and the inner circumferential surface of the central hole (401) At the same time, when the adhesive is fixed using the adhesive, the adhesive is uniformly applied between the outer circumferential surface of the spindle holder 3 and the inner circumferential surface of the central hole 401, thereby making it more firmly fixed.

또한, 상기 홀더고정구(4)의 외측에는 수나사부(402)를 형성함으로써 홀더고정구(4)를 상기 보빈몸통(1)의 양단부에 형성된 암나사부(101)에 나사 결합하게 되면 첨부도면 도 3에서 도시한 바와 같이 홀더고정구(4)에 고정된 스핀들홀더(3)가 보빈몸통(1)의 내측에 위치하게 된다.In addition, by forming a male screw portion 402 on the outer side of the holder fixture 4, when the holder fixture 4 is screwed to the female screw portion 101 formed at both ends of the bobbin body 1, the accompanying drawings in FIG. As shown in the drawing, the spindle holder 3 fixed to the holder fixture 4 is located inside the bobbin body 1.

따라서 스핀들홀더(3)는 금속재로 된 홀더고정구(4)와 보빈몸통(1)에 의해 이중으로 보호됨으로써 외부 충격에 대한 안전성이 더욱 향상된다.
Therefore, the spindle holder 3 is doublely protected by the holder fixing tool 4 and the bobbin body 1 made of metal, thereby further improving safety against external impact.

아울러, 상기와 같이 홀더고정구(4)를 보빈몸통(1)의 암나사부(101)에 나사 결합할 때는 상기 플랜지(2)의 중심부에 형성된 결합공(202)을 관통하여 나사 결합함으로써 홀더고정구(4)의 외측단부에 형성된 결합부(403)가 상기 플랜지(2)의 결합홈(203)에 끼워진 상태로 결합된다.In addition, when screwing the holder fixture 4 to the female threaded portion 101 of the bobbin body 1 as described above, the holder fixture (1) by screwing through the coupling hole 202 formed in the center of the flange (2) ( Coupling portion 403 formed at the outer end of 4) is coupled in the fitted state in the coupling groove 203 of the flange (2).

따라서 금속재로 된 보빈몸통(1)과, 금속재로 된 홀더고정구(4)간의 나사 결합으로 인해 합성수지재로 된 플랜지(2)의 고정이 이루어지기 때문에 보빈몸통(1)과 홀더고정구(4)의 나사 결합시에 과도한 힘이 작용하더라도 플랜지(2)에 직접적인 손상이 발생하는 것을 방지할 수 있을 뿐만 아니라, 플랜지(2)의 고정이 견고하게 이루어질 수 있게 된다.
Therefore, the bobbin body (1) and the holder fixture (4) of the bobbin body (1) and the holder fixing tool (4) of the metal material due to the fixing of the flange (2) made of synthetic resin is made Even if excessive force is applied at the time of screwing, it is possible not only to directly prevent damage to the flange 2, but also to fix the flange 2 firmly.

이상에서는 본 발명의 바람직한 실시 예에 대하여 도시하고 설명하였으나, 본 발명은 상술한 특정의 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에 의해 다양한 변형 실시나 응용이 가능한 것은 물론이고, 이러한 변형 실시나 응용 예는 본 발명의 기술적 사상이나 전망으로부터 개별적으로 이해돼서는 안 될 것이다.
