다음 내용은 본 출원인이 선 출원한 출원번호 10-2007-0105889 내용을 인용하고자 한다.The following contents are to be cited in the application No. 10-2007-0105889 the applicant previously filed.

제직준비기는 기종별로 권사기, 연사기, 가호기, 정경기, 연경기, 통경기, 주변기기 등 7개 분야의 섬유생산설비를 총칭하고 있다. 제직준비기가 이와 같이 다양한 범주의 서로 다른 기종들로 세세하게 분류되어 있는 원인은 원사입고(방적사 또는 필라멘트 장섬유사, 가연사 등) 이후 제직이 가능하도록 적정의 본수(本數)를 정경기에 감은, 빔상태에서 직기상에 걸고 통경작업으로 마무리하기까지 많은 작업과정을 거쳐야 하기 때문이다.Weaving preparation equipment is a general name for textile production equipment in seven fields such as winding machine, twisting machine, protector, warping machine, softening machine, tubing machine, and peripheral equipment. The reason why weaving preparations are classified into different models of various categories is that the proper number of yarns is wound around the warp to enable weaving after weaving yarn (spun yarn or filament filament yarn, false twisted yarn, etc.). This is because a lot of work has to be done to hang on the loom in the beam state and finish the work by telescopic work.

입고된 원사는 바로 직기에 공급되는 것이 아니라 제직용 준비과정들, 즉 감고(권취), 나누고(정경), 합치고(합사), 꼬임을 주고(가연), 풀칠하고, 직기 바디 의 잉아(目)까지 낱낱이 이어주는 다수의 작업이 까다롭게 진행되어 있어 각 세부공정 단계별로 실을 처리할 수 있는 최적의 설비는 형태와 기능도 다른 각각의 생산설비를 요구하고 있다.The received yarn is not fed directly to the loom, but weaving preparations: winding (coiling), dividing (canon), joining (marching), twisting (flamming), pasting, weaving of the loom body As many works are connected to each other, the optimal equipment that can process the yarn in each detailed process step requires each production equipment with different form and function.

제직준비기계는 일반적으로 권사, 정경, 가호, 통경 등의 공정으로, 이들 설비는 생산비용에서 원가절감기술로서 Process monitoring과 Data 입·출력기능, 원격진단, 혹은 Telemaintenace와 생산능력의 범용성과 유연성 부여이다.Weaving preparation machines are generally processes such as winding, canon, gaho, and telescope, and these facilities are cost-saving technologies in production cost, providing process monitoring and data input / output function, remote diagnosis, or generality and flexibility of telemaintenace and production capacity. to be.

구체적인 연사기의 기술동향은 다음과 같다.The technology trends of the concrete speaker are as follows.

Twisting machine은 획기적인 신기술 또는 신제품의 출현 없이, 기존 제품의 기능 향상 및 다변화가 Keypoint이다. Allma(Germany)사의 의류용 연사기(HT), 산자용 연사기(Techno Corder)와 ICBT(France)사의 Carpet yarn용 연사기(CDDT510), Tirecord용 연사기 등이다.Twisting machine is the key point of improvement and diversification of existing products without the emergence of innovative new technologies or new products. Allma (Germany) apparel yarn (HT), Sanjay (Techno Corder) and ICBT (France) Carpet yarn (CDDT510), Tirecord.

Two-for one twister로서 ICBT사의 DT354는 세번수 Yarn에 최고 3,400 t/m의 강연을 부여하기 위한 목적으로 Spindle 직경이 90/110mm, 공급 Pirn은 0.7~1.5kg 범위이며, Double flanged bobbin의 평행 권취와 개별 원추형 권취 시스템이 있다.As a two-for one twister, ICBT's DT354 has a spindle diameter of 90 / 110mm and a feed range of 0.7 ~ 1.5kg for the purpose of giving up to 3,400 t / m of lectures to three yarns, and parallel winding of double flanged bobbin. And individual conical winding systems.

또한, DT360은 중번수 및 세번수 Yarn에 중연과 약연을 부여하기 위하여 Spindle 직경이 140mm이며, Tangential belt로 Spindle을 구동하고, 고속 권취를 할 수 있을 뿐 아니라 염색용 Soft take-up package도 생산 가능하다. Flat yarn과 가공사용으로는 170mm spindle을 다양하게 사용할 수 있다.In addition, the DT360 has a spindle diameter of 140mm to give medium and weak yarns to the medium and third yarns. The spindle can be driven by a tangential belt, and it can be wound up at high speeds. It can also produce soft take-up packages for dyeing. Do. For flat yarns and machining applications, 170mm spindles are available.

Murata사는 독창적인 원추형 스핀들과 Tensor를 적용한 다단계 장력 System으로 안정된 Balloon 장력과 안정된 Balloon 형상을 유지하며, 가공된 실에 루프와 잔털의 형성을 방지하고, 각 부분마다 간단한 장력 조절도 할 수 있다. 스핀들과 o-ring 사이에 고정 Disk를 갖추고 있어서 스핀들의 진동이 직접적으로 Yarn에 전달되지 않는다. Tensor를 적용한 다단계 장력으로 30~300 denier yarn, 방적사, High multi-filament yarn, 불규칙 단면사 그리고 인터레이스사 등을 연사할 수 있다.Murata is a multi-stage tensioning system that employs a unique conical spindle and tensor that maintains stable balloon tension and a stable balloon shape, prevents the formation of loops and fine hairs on the machined thread, and enables simple tension adjustment for each part. Since a fixed disk is installed between the spindle and the o-ring, the vibration of the spindle is not transmitted directly to the yarn. With multi-sensor tension applied by Tensor, 30 ~ 300 denier yarns, spun yarns, high multi-filament yarns, irregular cross-section yarns and interlaced yarns can be twisted.

Three-for-one twister는 Saure Tritec Twister라는 이름으로 Hamel사에서 1993년 개발되어 출시되었는데, One-for one twister의 3배 또는 Two-for one twister의 1.5배에 이르는 생산성이 있어 향후 연사기의 주종을 이룰 것이다. Spindle shaft가 있는 외부 시스템과 평행으로 감긴 공급 Bobbin이 있는 내부 시스템은 같은 속도이지만, 서로 반대 방향으로 회전한다. 두 시스템은 원통 모양의 Thread-guiding으로부터 Yarn이 풀려나오고, Thread-guiding device에 집속된다. 실은 Hollow spindle 안으로 끌려 들어가고 상반 회전 시스템에 의해 즉시 두 번의 꼬임이 얻어지며, 실은 다시 외부 Thread-guiding device에 집속(集束)되고 Delivery roller에 감기기 전에 세 번째 꼬임이 얻어진다.Three-for-one twister was developed by Hamel in 1993 under the name of Saure Tritec Twister. It has three times the productivity of one-for-one twister or 1.5 times of two-for-one twister. Will come true. The inner system with the feed bobbin wound in parallel with the outer system with the spindle shaft is rotating at the same speed but in opposite directions. In both systems Yarn is released from the cylindrical thread-guiding and focused on the thread-guiding device. The thread is drawn into the hollow spindle and two twists are obtained immediately by the upper rotation system, and the thread is again focused on an external thread-guiding device and a third twist is obtained before winding on the delivery roller.

또한, 산업용 연사기의 용도는 Tire cord, 어망사, Timing belt용 Yarn, Rope용 Yarn, BCF carpet용 Yarn 및 Glass fiber의 연사이며 굵고 강한 실을 사용하기 때문에 Individual spindle system을 많이 적용하고, 특히 Glass fiber 연사에는 Ring twister를 사용하는 것이 보통이다. Direct cabling 방법은 한번의 작업으로 균형 잡힌 꼬임을 가진 2합 연사를 Cabling 하기 위한 것이다.In addition, the use of industrial twister is a yarn of tire cord, fishing net, yarn for timing belt, yarn for rope, yarn for yarn and BCF carpet, yarn for yarn and glass fiber, and it is applied to individual spindle system because it uses thick and strong thread, especially glass fiber It is common to use a ring twister for continuous shooting. The direct cabling method is to cabling two-ply consecutive speakers with a balanced twist in a single operation.

ICBT의 CP510/CP560을 나타내었는데, 꼬임이 없는 Single end는 Spindle의 아래로 들어가고, Ceramic disk의 구멍으로 나온다. Balloon이 형성되면서 이 첫 번째 실은 두 번째 실이 감긴 공급 보빈 주위를 회전하여 꼬임이 부여된 2합연사가 생성된다.ICBT's CP510 / CP560 is shown, with a single end without kinks going under the spindle and exiting the hole in the ceramic disk. As the balloon is formed, this first yarn is rotated around the supply bobbin on which the second yarn is wound, creating a twisted double twisted yarn.

그러나 기존 유리실의 합연사는 내굴곡성과 내마찰성이 나빠서 접히는 부분과 스치는 부분이 쉽게 떨어지는 단점이 있다.However, the twisted yarn of the existing glass room has a disadvantage in that the folding part and the rubbing part easily fall due to poor bend resistance and friction resistance.

종래의 함침조는 함침조 저 면에 설치된 침적롤러를 통해 유리실이 함침되므로써, 유리실이 절사시 통경작업이 어렵고, 함침량의 조절은 닙롤러 또는 나이프 등의 계량장치에 의하여 이루어지고 있으나 상기 계량장치에 코팅 용액이 누적 적층되어 정확한 계량이 어려운 문제점이 있다. Conventional impregnation tank is impregnated with glass chamber through the deposition roller installed on the bottom of the impregnation tank, the glass chamber is difficult to work when cutting the glass, and the impregnation amount is controlled by a measuring device such as nip roller or knife, but the measurement Accurate metering is difficult due to cumulative lamination of the coating solution on the device.

본 고안은 상기와 같은 문제점을 해결하기 위한 것으로 유리실에 도전성 고무 용액을 함침(含浸)하기 위한 함침조는 대향(對向)하는 양측면에 수직방향으로 상부가 열린 절개홈이 다수 개로 나란히 형성되게 하는 방법으로 본 과제를 해결하고자 한다.The present invention is to solve the problems as described above, the impregnation tank for impregnating the conductive rubber solution in the glass chamber to form a plurality of incision grooves open side by side in the vertical direction on both sides opposite to each other We will try to solve this problem.

이상과 같이 본 고안에 의하면 함침조의 양측면에 상부가 열린 절개홈에 의하여 유리실의 통경작업이 편리하고, 일정한 절개 폭에 의해 균일한 코팅 두께를 유지할 수 있는 특유한 효과가 있다.As described above, according to the present invention, the diameter of the glass chamber is convenient due to the incision grooves open at both sides of the impregnation tank, and there is a unique effect of maintaining a uniform coating thickness by a constant incision width.

본 고안은 도전성(導電性) 고무 용액(溶液)과 유리 실(textile glass yarns)을 이용한 도전성 합연사의 제조 장치에 있어서, 유리실(102)에 도전성 고무 용액을 함침(含浸)하기 위한 함침조(203)는 대향(對向)하는 양측면에 수직방향으로 상부가 열린 절개홈(204)이 다수 개로 나란히 형성되는 것을 특징으로 한다.The present invention is an impregnation tank for impregnating a conductive rubber solution in a glass chamber 102 in the apparatus for producing a conductive twisted yarn using a conductive rubber solution and glass glass yarns. 203 is characterized in that the plurality of incision grooves 204 open at the top in the vertical direction on both opposite sides are formed side by side.

이하, 첨부도면을 참조하여 본 고안의 바람직한 실시 예를 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1을 참조하면, 본 고안에 따른 도전성(導電性) 고무 용액(溶液)과 유리 실(glass yarn)을 이용한 도전성 합연사의 함침조를 나타낸 사시도이다.Referring to Figure 1, it is a perspective view showing an impregnation tank of a conductive spliced yarn using a conductive rubber solution and a glass yarn according to the present invention.

본 고안은 도전성(導電性) 고무 용액(溶液)과 유리 실(textile glass yarns)을 이용한 도전성 합연사의 제조 장치에 있어서, 유리실(102)에 도전성 고무 용액을 함침(含浸)하기 위한 함침조(203)는 대향(對向) 하는 양측면에 수직방향으로 상부가 열린 절개홈(204)이 다수 개로 나란히 형성되는 것을 특징으로 한다.The present invention is an impregnation tank for impregnating a conductive rubber solution in a glass chamber 102 in the apparatus for producing a conductive twisted yarn using a conductive rubber solution and glass glass yarns. 203 is characterized in that the plurality of incision grooves 204 open at the top in the vertical direction on both opposite sides are formed side by side.

또한, 상기 절개홈의 절개 폭은 0.1mm 내지 1.0mm가 바람직하다. 절개 길이는 함침조의 바닥에서 5mm 이상부터 이루어지고, 상부가 열린 절개홈(204)이 형성되는 것을 특징으로 한다.In addition, the cutting width of the cutting groove is preferably 0.1mm to 1.0mm. The incision length is made from 5mm or more from the bottom of the impregnation tank, it is characterized in that the top is open incision groove 204 is formed.

상기 절개 폭이 0.1mm 미만은 유리실의 관통이 어려워 함침이 잘 안 되고, 1.0mm 초과는 도전성 고무 용액이 흘러나오는 문제점이 있다.If the incision width is less than 0.1mm, the penetration of the glass chamber is difficult to impregnate, and more than 1.0mm has a problem that the conductive rubber solution flows out.

그러므로 상기와 같은 0.1mm 내지 1.0mm의 절개 폭으로 형성된 절개홈(204)에 의해 유리실(102)이 도전성 고무 용액 속을 관통해도 용액이 흘러나오지 않는다.Therefore, even if the glass chamber 102 penetrates through the conductive rubber solution by the incision groove 204 formed with the cutting width of 0.1 mm to 1.0 mm, the solution does not flow out.

왜냐하면, 도전성 고무 용액의 점도가 5,000 cps 이상이고, Thixotropic Index가 2.0 이상이면 용액의 점성이 높아 1.0mm 이하의 틈으로는 용액이 흘러나오지 않는다.This is because if the viscosity of the conductive rubber solution is 5,000 cps or more and the Thixotropic Index is 2.0 or more, the viscosity of the solution is high and the solution does not flow into the gap of 1.0 mm or less.

이상과 같이 본 고안에 의하면 함침조의 양측면에 상부가 열린 절개홈에 의 하여 유리실의 통경작업이 편리하고, 일정한 절개 폭에 의해 균일한 코팅 두께를 유지할 수 있는 특유한 효과가 있다.According to the present invention as described above, the opening of the glass chamber is convenient due to the incision grooves open at both sides of the impregnation tank, and has a unique effect of maintaining a uniform coating thickness by a constant incision width.

종래의 함침조는 함침조 저 면에 설치된 침적롤러를 통해 유리실이 함침되므로써, 유리실이 절사시 통경작업이 어렵고, 함침량의 조절은 닙롤러 또는 나이프 등의 계량장치에 의하여 이루어지고 있으나 상기 계량장치에 코팅 용액이 누적 적층되어 겔화되는 부분이 있었다. Conventional impregnation tank is impregnated with glass chamber through the deposition roller installed on the bottom of the impregnation tank, the glass chamber is difficult to work when cutting the glass, and the impregnation amount is controlled by a measuring device such as nip roller or knife, but the measurement The device had a portion where the coating solution was accumulated and gelated.

따라서, 본 고안은 상기와 같은 문제점을 해결하기 위한 것으로 유리실에 도전성 고무 용액을 함침(含浸)하기 위한 함침조는 대향(對向)하는 양측면에 수직방향으로 상부가 열린 절개홈이 다수 개로 나란히 형성되게 하는 방법으로 본 과제를 해결했다. Therefore, the present invention is to solve the above problems, the impregnation tank for impregnating the conductive rubber solution in the glass chamber is formed side by side with a plurality of incision grooves open in the vertical direction on both sides facing each other. We solved this problem in a way.

그러므로 본 고안은 상기 함침조(203)의 상부가 열린 절개홈(204)을 통해 유리실(102)의 절사시에도 편리한 통경작업이 가능하고, 일정한 절개 틈이 함침량의 계량장치 역할을 함으로써 기존의 닙롤러나 나이프 등의 계량장치가 없어도 균일한 코팅 두께를 유지할 수 있는 특징이 있다. Therefore, the present invention enables convenient diameter operation even when cutting the glass chamber 102 through the incision groove 204 where the upper part of the impregnation tank 203 is opened, and a constant incision gap serves as a measuring device for impregnation amount. There is a feature that can maintain a uniform coating thickness even without a measuring device such as a nip roller or knife.

도 1은 본 고안에 따른 도전성(導電性) 고무 용액(溶液)과 유리 실(glass yarn)을 이용한 도전성 합연사의 함침조를 나타낸 사시도.1 is a perspective view showing an impregnation tank of a conductive spliced yarn using a conductive rubber solution and a glass yarn according to the present invention.
