Description
본발명은 퀼팅머신의 니들대를 승강시킴에 있어서, 매우 정숙한 작동을 할 수 있도록 하면서 진동이 최소화 되고 승강속도를 최대화시켜 생산성 향상과 신뢰성 극대화를 이룰수 있도록 하기 위한 것이다.In the present invention, in order to elevate the needle bar of the quilting machine, it is possible to achieve a very quiet operation while minimizing vibration and maximizing the lifting speed to achieve productivity improvement and maximum reliability.
주지된 바와 같이 니들대를 승강시키는 종래 구성을 살펴보면,Looking at the conventional configuration for lifting the needle bar as known,
다수의 크랭크 휠을 축착시킨 크랭크 축을 퀼팅머신 상측에 가로질러 설치하고, 각각의 크랭크 휠에는 승강봉과 연결설치된 로드를 설치하되, 크랭크 축 일단부에 요동로드를 설치하여 상기 요동로드와 연결되게 모타의 동력과 연결설치된 크랭크 휠의 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 단축 되는 등의 폐단이 따랐던 것이다.Install a crank shaft on which a plurality of crank wheels are condensed across the upper side of the quilting machine, and install a rod connected to the lifting bar on each crank wheel, and install a rocking rod at one end of the crank shaft to connect with the rocking rod The problem was that the crank wheel had to go through two stages of crank motion until the power of the motor was transferred to the needle bar by connecting and installing the long rod of the crank wheel, which was connected to the power. Therefore, the shock and vibration were severe and the swing speed was limited. As a result, the decline in productivity and shortening of lifespan was followed.
따라서 본발명은 전술한 종래 니들대 승강장치에 따른 제반문제점을 감안하여 안출된 것으로, 특히 동력전달을 헬리컬기어 또는 베벨기어를 이용하여 시킬수 있도록 하고, 상기 헬리컬기어 또는 베벨기어의 종동축 선단부에는 원판캠을 설치하여 이곳에 편심돌출되게 베어링(또는 짧은 축을 돌출 설치하여 됨)을 돌출고정시키며, 니들대 승강축에 ""형의 슬라이드 홈을 가진 지지구를 고정설치하여, 상기 슬라이드홈이 원판캠에 편심 돌출된 베어링(또는 짧은 축)에 끼워지게 함으로써 원판캠의 회전운동을 승강운동으로 변화시킬수 있게 하고, 이에 따라 니들대를 고속으로 승강시킬수 있게 되어 생산량을 극대화시킬수 있게 하며, 진동이 없이 부드럽게 작동되기 때문에 매우 정숙한 작동 및 수명연장 효과가 극대화되게 하려는데 그 목적이 있는 것이다.Therefore, the present invention has been devised in view of the above-mentioned problems according to the conventional needle bar lifting device, and in particular, the power transmission can be made by using a helical gear or a bevel gear, and a disc on the driven shaft end of the helical gear or bevel gear The cam is installed so that the bearing (or the short shaft is protruded) is fixed to the eccentric protrusion and the " By fixing the support with the slide groove of the "type, it is possible to change the rotational motion of the disc cam by the lifting motion by allowing the slide groove to be fitted to the bearing (or short shaft) eccentrically protruding from the disc cam. The purpose of the purpose is to maximize the output of the needle bar by raising and lowering the needle bar at high speed.

퀼팅머신의 니들대를 승강시키는 장치를 구성함에 있어서,In constructing a device for elevating the needle bar of the quilting machine,
가이드고정판(1)에 원형구멍(2)을 뚫어 이곳에 주축(3)과 연결설치된 헬리컬기어(4)와, 상기 헬리컬기어(4)와 치합된 헬리컬기어(4`)의 종동축(5)에 고정설치된 원판캠(6)을 설치하고, 상기 원판캠(6)에 편심되게 끔 베어링(7) <또는 짧은 축을 돌출되게 끔 설치하여도 됨>을 설치하며,A helical gear (4) installed in connection with the main shaft (3) by drilling a circular hole (2) in the guide fixing plate (1), and the driven shaft (5) of the helical gear (4`) engaged with the helical gear (4). The disc cam 6 fixedly installed on the disc cam 6, and installs the bearing 7 <or may be installed so as to protrude a short shaft> to be eccentric to the disc cam 6,
하부에 니들대(8)를 고정설치한 니들대 승강축(9)에 후면에 ""형 슬라이드홈(10)을 가진 지지구(11)를 볼트등로써 고정설치하여 상기 베어링(7)이 슬라이드홈(10)에 끼워지도록 조립하여, 주축(3)에 동력이 전달되면 주축(3)에 설치된 헬리컬기어(4)가 회전하면서 헬리컬기어(4`)를 회전시켜 줌에 따라 동력이 직각방향으로 전달되게 되고, 상기 헬리컬기어(4`)와 조립고정된 종동축(5)에 의해 원판캠(6)이 회전하면서 니들대(8)를 승강시키도록 구성한 것이다.On the back of the needle bar lifting shaft (9) with the needle bar (8) fixed to the lower part, The support 11 having the "type slide groove 10" is fixedly installed with a bolt or the like so that the bearing 7 is fitted to the slide groove 10, and when the power is transmitted to the spindle 3, the spindle 3 As the helical gear 4 installed in the rotating shaft rotates the helical gear 4`, power is transmitted in a right angle direction, and the helical gear 4` and the driven shaft 5 assembled and fixed are The disc cam 6 is configured to elevate the needle bar 8 while rotating.
미설명 부호 12는 안내봉, 13, 13`, 13a, 13a`는 가이드, 14는 니들대이다.Reference numeral 12 is a guide rod, 13, 13 ', 13a and 13a' are guides, and 14 is a needle bar.
이와 같이 구성된 본발명은 동력이 전달될때 주축(3)에 설치된 헬리컬기어(4)가 종동축(5)과 연결설치된 헬리컬기어(4`)를 회전시킴으로써 종동축(5) 선단에 고정설치된 원판캠(6)이 부드럽게 회전하게 되고, 또 원판캠(6)에는 편심되게 베어링(7)을 돌출설치하여, 상기 베어링(7)이 니들대 승강축(9)에 고정설치된 ""형 슬라이드홈(10)에 끼워져 원판캠(6) 편심량의 두배거리 만큼 니들대 승강축(9)을 승강시키는데 이때 니들대 승강축(9)에 고정설치된 ""형 슬라이드홈(10)은 수평방향으로 길게 형성되어 있는 상태이므로 원판캠(6)이 회전하는 과정에서 좌·우측으로 편심되더라도 원활하게 니들대 승강축(19)을 승강시킬수 있게 되며, 또 헬리컬기어(4)(4`)의 특성이 치차의 접속면적을 크게한 것이기에 동력전달시 마찰소음이 거의 없는 데다가 종래와 같은 크랭크 구조가 아니기에 고속회전이 용이하면서도 소음이 없는 특성이 따르게 되는 것이다.The present invention configured as described above is a disc cam fixed to the end of the driven shaft (5) by rotating the helical gear (4`) is connected to the driven shaft (5) installed in the main shaft (3) when the power is transmitted (6) rotates smoothly, and the disc cam (6) protrudes the bearing (7) eccentrically, so that the bearing (7) is fixed to the needle bar lifting shaft (9) "It is inserted into the type slide groove (10) and elevates the needle bar lifting shaft (9) by a distance twice the eccentricity of the disc cam (6) is fixed to the needle bar lifting shaft (9)" "Shape slide groove 10 is formed in the horizontal direction long, so even if the disc cam 6 is eccentric to the left and right in the process of rotating it is possible to smoothly lift the needle bar lifting shaft 19, and helical Since the gears 4 and 4` have a large connection area of the gear, there is little frictional noise during power transmission, and since the crank structure does not have a conventional crank structure, high-speed rotation is easy and noise-free.
따라서 본발명은 종래 크랭크 축을 이용한 구조에 비하여 매우 고속으로 니들대(14)를 승강시킬수 있어 생산량을 배가 시킬수 있을뿐만 아니라 진동 및 소음이 없어 작동시 정숙하고, 또 수명이 매우 길게 유지될 수 있게 되는 것이다. 또한 상기한 헬리컬기어(4)(4`) 대신에 베벨기어를 사용하여도 그 효과는 동일하게 된다.Therefore, the present invention can elevate the needle bar 14 at a very high speed in comparison with the structure using a conventional crankshaft, which not only can double the output, but also can be kept quiet and operate for a long time without vibration and noise. will be. In addition, even if a bevel gear is used instead of the helical gear 4 (4 ′), the effect is the same.
이상 설명한 바와 같이 본발명은 종래 크랭크 축을 이용하여 니들대를 승강시키는 구조에 비하여 니들대의 승강속도를 배가시킬수 있게 되므로 생산량을 극대화 시킬수 있고, 또 진동 및 소음이 없어 매우 정숙하며, 더불어 수명연장효과와 신뢰성을 극대화 시킬수 있게 되는 매우 유용한 발명인 것이다.As described above, the present invention can double the lifting speed of the needle bar compared to the structure of elevating the needle bar by using the crankshaft, thus maximizing the yield, and there is no vibration and noise. It is a very useful invention that can maximize the reliability.
