본 고안은 미싱을 이용한 재봉실을 절단할 수 있는 절단할 수 있는 절단장치가 부설된 미싱용 침판에 관한것으로 특히, 절단의 신뢰성을 높게 하기위함과 절단시 잔사가 발생되지 않도록 구조적 단순화를 도모하고저 개발된 미싱용 침판의 사절장치를 제공하는 그 목적이 있다.The present invention relates to a sewing machine needle plate equipped with a cutting device capable of cutting a sewing thread using a sewing machine, and in particular, in order to increase the reliability of cutting and to achieve structural simplification so that no residue is generated during cutting. It is an object of the present invention to provide a thread trimming device for a needle needle for a sewing machine.
일반적으로 미싱용 침판 자체에 사절장치가 부설된것은 본인의 선출원공고된 실용신안등록 출원 제83-2053호(공고번호 : 제84-247호)로 소개된 바와같이 미싱에 의한 재봉작업시 필요에 의해 재봉실을 절단하고자할 때는 재봉직물을 당기면서 재봉실이 절단도에 진입되면서 절단이 이루어질 수 있는 형태로 소개되고 있으나, 상기한 기술내용에서는 절단도의 구조에서 절단칼날 부위가 원호상으로 이루어져 제작시 상당한 어려움이 있고, 또한 절단도로 진입되는 재봉실이 정확히 칼날부위에 접촉되지 않아 절단의 신뢰성이 낮은 결점이 있었고, 또한, 일본특허공보(소 42-15143호)에 게재된 기술내용의 경우는 비교적 재봉실에 대한 사절의 신뢰성은 높으나, 사절된 재봉사를 계속적인 작업을 위한 파지기능의 부실로 인해 미세한 (2-3㎜정도)잔사가 발생되어 재봉사의 소모는 물론 작업상의 환경을 해치는 결점이 있었다.In general, the thread trimming device is installed on the needle plate for sewing machine itself, as introduced in the Utility Model Registration Application No. 83-2053 (Notification No. 84-247) published by the applicant. When the sewing thread is to be cut by the sewing fabric is introduced in the form that can be cut while the sewing thread enters the cutting degree while pulling the sewing fabric, but in the above description, the cutting blade in the structure of the cutting diagram made of circular arc shape There is a considerable difficulty, and there is a drawback that the reliability of cutting is low because the sewing thread entering the cutting degree does not exactly touch the blade portion, and in the case of the technical contents disclosed in Japanese Patent Publication No. 42-15143, it is relatively sewing thread. Reliability of thread trimming is high, but fine (2-3㎜) residue is generated due to poor gripping function for continuous work of threaded sewing thread Consumption of the sewing thread, as well as a defect that hurts the working environment.
따라서 본 고안은 이와같은 종래의 결점을 해소시키기위해 V자형 칼날을 양쪽으로 형성시킨 절단도를 채택함과 침판상부로 안착조합하여 된것으로 절단의 신뢰성을 증대와, 연속재봉작업에 필요한 재봉사의 파지역할을 할 수 있게 된것으로서 그 실시예를 도시한 첨부도면에 따라 그 구멍 및 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention adopts the cutting degree in which the V-shaped blade is formed on both sides to solve such a conventional defect, and it is combined with the seat plate to increase the reliability of cutting, and the sewing thread required for continuous sewing work. According to the accompanying drawings showing the embodiments as being able to play a role and the effect will be described in detail as follows.
바늘통과공(1a)과 동일중심 수평위치의 침판(1) 상면에 안착호(1b)과, 상기 바늘통과공(1a)과 연장되 유도장공(1c)을 양단부에 V자형 칼날(2a)을 형성한 절단도(2)를 별도 구비하여 상기 안착홈(1b)에 절단도(2)를 조합하여 나사결합으로 이루어진 구성으로서 미 설명부호 3은 바늘이고, 4는 직물이며, S는 재봉실인 것이다.A V-shaped blade 2a is provided at both ends of a seating arc 1b on the upper surface of the needle plate 1 at the same horizontal position as the needle passing hole 1a, and a guide hole 1c extending to the needle passing hole 1a. It is provided with a separate cut (2) formed by combining the cutting 2 (2) in the seating groove (1b) consisting of a screw coupling, reference numeral 3 is a needle, 4 is a fabric, S is a sewing thread .
이와같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effects of the present invention configured in this way in detail as follows.
일반적인 미싱의 재봉구동에 따라 바늘통과공(1a)을 상, 하 구동하면서 재봉작업을 하던중 필요에 의해 재봉실(S)을 절단하고자 할 경우에는 도면 제 2a 도에 도시된 바와같은 바늘(3)이 침판(1)으로 부터 이격된 상태에서 직물(4)을 화살표 방향으로 잡아 당기게되면 직물(4)에 꿰어있던 재봉실(S)의 위치가 바늘통과공(1a)에서 연장된 유도장공(1c)을 따라 이동되면서 침판(1)의 안착홈(1b)에 나착된 절단도(2)의 일단부에 형성된 V자형 칼날(2a)부위에 도면 제 2b 도에 도시된 바와같이 진입되어 절단되는 상태가 된다.According to the sewing operation of a general sewing machine, the needle threading hole (1a) while driving up and down while sewing work to cut the sewing thread (S) as needed, the needle (3) as shown in Figure 2a When the fabric 4 is pulled in the direction of the arrow in the state separated from the needle plate 1, the position of the sewing thread S sewn on the fabric 4 is extended to the guide hole 1c extending from the needle passing hole 1a. As shown in FIG. 2B, the state of being cut into the V-shaped blade 2a formed at one end of the cutting diagram 2 attached to the seating groove 1b of the needle plate 1 while moving along do.
이때, 본 고안에 의한 절단도(2)는 실질적으로 재봉실(S)에 대해 절취기능을 수행하는 칼날부위가 V자형칼날(2a)로 형성되어있기 때문에 진입의 신뢰성과 절단의 신뢰성이 증대되는 것이고, 특히, V자형이라는 칼날의 형상과 재봉실(S)의 자체 탄력성에 의해 쐐기형태로 진입절단되면서 절단된 재봉실(S)의 상단은 V자형칼날(2a)에 절단시 인장되었던 상태에서 자체물성에 의해 부풀어지면서 쐐기에 물리는 형태로 파지되어 연속적인 재봉작업을 시도할 수 있도록 됨이 큰 특징인 것이다.At this time, the cutting degree (2) according to the present invention is because the blade portion for performing the cutting function for the sewing thread (S) substantially is formed by the V-shaped blade (2a) is to increase the reliability of the entry and the reliability of the cutting In particular, the upper end of the cutting thread (S) is cut into the wedge shape by the shape of the blade called the V-shaped and the elasticity of the sewing thread (S) in its own physical properties in the state of being tensioned when cutting the V-shaped blade (2a). It is characterized by being able to try a continuous sewing work is held in the form of being swelled by being swollen by the swelling.
또한, 장기간 사용함에 따라 일측단의 V자형칼날(2a)이 마모되면 타측에 형성된 칼날부위로 위치변경하여 결합 사용하므로서 장기간 사용이 가능케 된것이다.In addition, when the V-shaped blade (2a) of one end is worn with long-term use, it is possible to use for a long time by changing the position to the blade portion formed on the other side.
즉, 본 고안은 본인이 선출원공고된 종래의 사절장치에서 문제점으로 대두되었던 재봉실(S)에 대한 절단의 신뢰성을 증대시키게됨과 구조적 단순화를 가져오게 된것이다.In other words, the present invention is to increase the reliability of the cutting for the sewing thread (S), which was raised as a problem in the conventional trimming device that the applicant has been filed and brought to the structural simplification.
