Abstract

[청구범위에 기재된 고안이 속한 기술분야][Technical field to which the invention described in the claims belong]

퀼팅머신의 니들대 승강장치에 관한분야Needle bed lifting device of quilting machine

[고안이 해결하려고 하는 기술적 과제][Technical challenges that drafts try to solve]

종래에는 모타의 동력이 니들대까지 전달되기까지 2단계로 크랭크 연동부를 거치는 구조이기에 충격과 소음이 극심하고 속도에 한계가 따랐던 것임.Conventionally, since the motor goes through the crank linkage in two stages until the power of the motor is transmitted to the needle bar, the impact and noise were severe and the speed was limited.

[고안의 해결방법의 요지][Summary of solution of draft]

본 고안은 퀼팅머신 상측에 설치된 크랭크축을 종래와 같이 또 다른 크랭크휠과 로드로서 요동운동시키지 아니하고, 회전운동시킴으로서 니들대의 승강이 곧바로 이루어지게 하여 소음극소화와 충격극소화를 이룰 수 있도록 하며 더불어 속도를 크게 증대 시킬 수 있어 생산성 향상에 크게 기여할 수 있도록 한 것이다.The present invention does not oscillate the crankshaft installed on the upper side of the quilting machine as another crank wheel and rod as in the prior art, but by rotating the needle, the lifting and lowering of the needle bar is performed immediately, thereby minimizing the noise and minimizing the impact, and greatly increasing the speed. It can make a big contribution to productivity improvement.

Description

퀼팅머신의 니들대 승강장치Needle bar lifting device of quilting machine

본 고안은 퀼팅머신의 니들대를 승강시킴에 있어서, 보다 더 정숙한 작동을 할 수 있으면서, 보다 더 빠른속도로 승강할 수 있도록하여 생산성 향상과 신뢰성 극대화를 이룰 수 있도록 하려는데 그 목적이 있는 것이다.The object of the present invention is to raise and lower the needle bar of the quilting machine, and to achieve a more quiet operation, and to be able to ascend at a higher speed, thereby improving productivity and maximizing reliability.

본 고안은 퀼팅머신의 니들대 승강장치에 관한 것이다.The present invention relates to a needle bar lifting device of the quilting machine.

주지된 바와같이 니들대를 승강시키는 종래구성을 살펴보면, 다수의 크랭크휠을 축착시킨 크랭크축을 퀼팅머신 상측에 가로질러 설치하고, 각각의 크랭크휠에는 승강봉과 연결 설치된 로드를 설치하되, 크랭크축 일단부에 요동로드를 설치하여 상기 요동로드와 연결되게 모타의 동력과 연결설치된 크랭크휠의 장로드를 연결설치하여 결국 모타의 동력이 니들대까지 전달되기까지 2단계의 크랭크 운동부를 거쳐야 되는 문제점이 따랐으며, 이에 따라 충격과 진동이 극심하고 요동속도에 한계가 따랐기에 생산성 저하와 더불어 수명이 단축되는 등의 폐단이 따랐던 것이다.As is known, the conventional configuration of elevating the needle bar is installed across the upper side of the quilting machine, and the crank shaft on which the plurality of crank wheels are condensed, and each crank wheel is provided with a rod installed in connection with the elevating rod, one end of the crank shaft The oscillating rod was installed on the crank wheel's long rod connected to the oscillating rod to be connected to the oscillating rod. As a result, shocks and vibrations were severe and the speed of rotation was limited, resulting in reduced productivity and shortened life.

본 고안은 퀼팅머신 상측에 설치된 크랭크축을 종래와 같이 또 다른 크랭크휠과 로드로서 요동운동시키지 아니하고 회전운동시킴으로써 니들대의 승강이 곧바로 이루어지게 하여, 소음극대화화 요동시의 충격극소화를 이룰 수 있도록 하며, 더불어 요동속도를 극대화시켜 생산성 향상에 크게 기여할 수 있도록 하려는 것이다.The present invention is to move the crankshaft installed on the upper side of the quilting machine as another crank wheel and rod as a conventional rotation without rotating the needle, so that the lifting of the needle bar is made immediately, to achieve the impact minimization during noise maximization swing This is to maximize the swing speed so that it can greatly contribute to productivity improvement.

퀼팅머신의 니들대 승강장치에 있어서, 퀼팅머신의 상측에 양단에 크랭크휠(2)(2')을 축설한 크랭크축(1)을 2∼3조 동일한 높이와 간격으로 설치하여 이를 타이밍밸트(3)과 타이밍기어(4)로서 회전시키되, 상기 크랭크휠(2)(2')에는 니들대(5)와 연결된 고정봉(6)과 흔들림을 예방해주는 안내봉(7)을 연결고정시킨 승강대(8) 및 크랭크로드(9)를 베어링(10)으로 유설하여 크랭크축(1)의 회전에 의해 니들대(5)가 바로 승강토록 하며, 상기 고정봉(6)과 안내봉(7)은 가이드고정프레임(11)에 의해 안내되도록 구성함으로써 니들대(5)가 안정적으로 승강할 수 있도록 하였다.In the needle bar elevating device of the quilting machine, the crankshaft (1) having the crank wheels (2) (2 ') installed at both ends on the upper side of the quilting machine is installed at the same height and spacing of 2 to 3 pairs, and the timing belt 3) and a lifting gear which is rotated as a timing gear 4, and the crank wheel 2, 2 'is fixed to a fixed rod 6 connected to the needle bar 5 and a guide rod 7 to prevent shaking. (8) and the crank rod (9) in the bearing 10, the needle bar (5) is raised and lowered immediately by the rotation of the crankshaft (1), the fixed rod (6) and the guide rod (7) The guide bar is configured to be guided by the frame 11 so that the needle bar 5 can be stably elevated.

미설명 부호 12는 니들, 13은 실채기축, 14은 실채기 구동장치이다.Reference numeral 12 denotes a needle, 13 a thread take-up shaft, and 14 a thread take-up driving device.

이와같이 구성된 본 고안은 타이밍벨트(3)와 타이밍기어(4)에 의해 크랭크축(1)이 회전하게 됨으로써, 종래 2단계로 크랭크휠과 로드를 설치하여 니들대(5)를 승강시킬 때와는 달리 구성이 매우 간단해지게 되고, 더불어 승강속도 증대가 이루어질 수 있게 되는 것이다.The present invention constructed as described above has the crankshaft (1) rotated by the timing belt (3) and the timing gear (4), and when the needle bar (5) is elevated by installing a crank wheel and a rod in a conventional two-step Otherwise, the configuration becomes very simple, and the lifting speed can be increased.

즉, 제1도∼제3도에서 보는 바와 같이 크랭크축(1)을 구동시키는 동력은 타이밍밸트(3)와 타이밍기어(4)에 의하여 전달되며, 이에 따라 크랭크휠(2)(2')의 회전을 크랭크로드(10)가 승강운동으로 전환하여주되, 이에 크랭크로드(9)와 연결설치된 승강대(8)가 니들대(5)와 연결된 고정봉(6)과 안내봉(7)에 고정된 상태에서 승강하게 됨으로써, 니들대(5)가 안정적으로 흔들림없이 승강작동할 수 있게되는 것이며, 따라서 크랭크휠(2)(2')이 고속회전하더라도 소음이 극소화됨은 물론, 승강대(8)의 상사점 및 하사점에서 발생되는 충격이 거의 없게되는 것이다(즉, 크랭크휠이 회전하는 데다가 하나의 로드로서 승강시킬 수 있는 구성이기 때문에).That is, as shown in FIGS. 1 to 3, the power for driving the crankshaft 1 is transmitted by the timing belt 3 and the timing gear 4, and thus the crank wheels 2 and 2 '. The crank rod 10 is converted to the lifting movement of the rotation of the crank rod, and the lifting table 8 connected to the crank rod 9 is fixed to the fixed rod 6 and the guide rod 7 connected to the needle bar 5. In this state, the elevating stand 5 is capable of raising and lowering the needle bar 5 stably without shaking. Therefore, even if the crank wheels 2 and 2 'rotate at high speed, the noise is minimized, and of the lifting stand 8. There is little impact occurring at the top dead center and the bottom dead center (i.e., because the crank wheel rotates and can be lifted as a rod).

상술한 바와같이 본 고안은 타이밍벨트(3)에 의해 회전하는 크랭크휠(2)(2')에 니들대(5)를 연결설치한 고정봉(6) 및 안내봉(7)을 고정시킨 승강대(8)를 크랭크로드(9)로써 연결설치한 것으로 구성이 매우 간단하고 소음이 크게 줄어들며, 생산성을 극대화 시킬 수 있는 매우 유용한 고안이 것이다.As described above, the present invention provides a lift bar on which a fixed rod 6 and a guide rod 7 are fixed to a crank wheel 2 and 2 'which are rotated by a timing belt 3. (8) is installed as a crank rod (9) is a very simple configuration, greatly reduced noise, it is a very useful design that can maximize productivity.
