Abstract

A weft injection guide groove (tunnel) is comprised in front of a body of an air jet weaving machine even in a state of weaving (drawing-in). The weft guide groove checks the state of a spraying pressure or a body by measuring a compress-spraying air pressure inside of the weft injection guide groove. According to measured results, replacements or fixation are performed or the spraying pressure is modulated to optimize an injection of the weft passing through the weft injection guide groove, which can form an ideal weaving. A spray nozzle is installed in a side of the bottom of a main block, which is connected to an air compressor; a pitot tube is integrally installed in the opposite side of the spray nozzle; hence, the spraying pressure applied to the pitot tube can be measured by a pressure sensor and the pressure can be displayed on a display window installed on top of the main block. The air pressure of the weft injection guide groove is measured by using the spraying air pressure measuring machine and then required means can be devised.

Description

직기의 위사공급용 분사공기압 측정기{SPRAYING AIR PRESSURE MEASURING APPARATUS FOR SUPPLYING WEFT OF LOOM}SPRAYING AIR PRESSURE MEASURING APPARATUS FOR SUPPLYING WEFT OF LOOM}

본 발명은 에어제트직기를 이용한 직물제직시 바디 전면에 구성된 위입안내홈(바디터널)을 지나는 압축공기의 분사압력을 측정, 바디의 상태를 확인하여 교체하거나 수리할 수 있게 함은 물론, 항상 정압의 상태로 분사될 수 있게 조정함으로서 압축분사공기에 의해 이루어지는 위사의 위입상태가 최적의 조건을 유지할 수 있게 하여 이상적인 직물제직이 이루어질 수 있게 하고, 필요이상의 압축공기낭비를 예방, 에너지를 절감할 수 있게 한 위사공급용 분사공기압 측정기에 관한 것이다.The present invention measures the injection pressure of the compressed air passing through the inlet guide groove (body tunnel) configured on the front of the body when weaving the fabric using the air jet loom, it is possible to replace or repair by checking the state of the body, of course, always positive pressure By adjusting it to be sprayed in the state of the weft, the weaving state of the weft made by the compressed spray air can maintain the optimum conditions, so that the weaving of the ideal fabric can be achieved, and the compressed air can be prevented more than necessary, and energy can be saved. It relates to an injection air pressure measuring instrument for weft supply.

일반적으로 에어제트직기는 위사의 위입을 위하여, 메인노즐이나 서브노즐을 구비하고 있으며, 메인노즐은 변사부 일측에 설치되어 위입초기에 개구된 경사 사이로 위사가 위입될 수 있게 하는 기능을 하게 된다.In general, the air jet loom is provided with a main nozzle or a sub-nozzle for the upper weft of the weft yarn, the main nozzle is installed on one side of the toilet to function to allow the weft weft between the inclined opening at the beginning of the upper weft.

서브노즐은 바디에 등간격으로 설치한 다음 바디의 위입안내홈을 통하여 위입되는 위사에 압축분사공기압을 보충하여 이상적인 위입이 이루어질 수 있게 하고 있다.Sub-nozzles are installed at equal intervals in the body, and then supplement the compressed jet air pressure into the weft thread through the inlet guide groove of the body so that the ideal indentation can be achieved.

따라서 에어제트직기를 이용한 직물제직시 위사와 함께 바디전면에 구성된 위입안내홈을 지나는 압축분사공기의 분사압력상태는 이상적인 제직조건의 필수요소 중 하나이다.Therefore, when weaving fabrics using an air jet loom, the injection pressure of the compressed jet air passing through the indentation guide groove formed on the front surface of the body is one of the essential elements of the ideal weaving conditions.

제직중 메인노즐이나 서브노즐로부터 분사되는 압축공기의 분사압력 미흡이나, 분사상태가 정상적이지 않을 경우에는 위사의 처짐현상이나 위사의 이탈현상, 위사줄, 절사 등의 문제발생이 야기되기 때문에 통상적으로 제직현장에서는 필요이상의 압력으로 압축공기를 분사하는 경우가 많아지게 되고, 따라서 에너지낭비를 초래하게 될 뿐 아니라, 단순히 위입만을 위하여 분사압력을 높여 제직한다는 것은 바람직한 제직조건이라 할 수 없다.Insufficient injection pressure of compressed air injected from the main nozzle or sub nozzle during weaving, or if the injection state is not normal, it may cause problems such as deflection of the weft, separation of the weft, weft lines, and cutting. At the weaving site, compressed air is often injected at a pressure higher than necessary, thus not only causing waste of energy, but simply increasing the injection pressure for weaving is not a desirable weaving condition.

에어제트직기의 위입제어장치와 관련한 선행기술을 검토하여 보면, 위사의 위입(비주)시간을 일정하게 하기 위하여 메인노즐의 분사압력과 서브노즐의 분사압력과의 사이에 일정한 관계를 유지한채로 양측의 분사압력을 동시에 제어할 수 있도록 한 일본국 특개소60-110952(특허문헌 1)가 제공된바 있다.Considering the prior art related to the inlet control device of the air jet loom, in order to make the indentation time of the weft thread constant, it is necessary to maintain a constant relationship between the injection pressure of the main nozzle and the injection pressure of the subnozzle. Japanese Patent Laid-Open No. 60-110952 (Patent Document 1) has been provided in which the injection pressure can be simultaneously controlled.

또한 위사의 저류량의 변화를 검출함으로서 위사의 위입속도를 간접적으로 측정하고, 간접측정된 결과에 의거하여 메인노즐 및 서브노즐의 분사압력 및 분사타이밍을 제어케 한 일본국 특개소60-162838호(특허문헌 2)가 제시된바 있다.In addition, Japanese Patent Application Laid-Open No. 60-162838, which indirectly measures the inlet velocity of the weft by detecting changes in the amount of storage of the weft, and controls the injection pressure and the injection timing of the main nozzle and the subnozzle based on the indirect measurement result. (Patent Document 2) has been presented.

또다른 수단으로서, 서브노즐군에 대한 위입조건으로서, 분사압력이나 분사기간을 가장 적합한 수치로 설정하는 구성으로 된 대한민국 특허공고번호특1991-298호 "에어제트직기의 위입제어장치"(특허문헌 3)가 제공된바 있다.As another means, Korean Patent Publication No. 1991-298 “Air Jet Loom Control Device”, which is configured to set the injection pressure and the injection period to the most suitable numerical value as an infiltration condition for the sub-nozzle group (Patent Document 3) has been provided.

그러나 상기 특허문헌에 제시된 위입제어수단의 경우, 에어제트직기의 바디에 구성된 위입안내홈의 각 구간별로 분사압력을 측정하는 수단에는 불편함이 있는 것이었다.However, in the case of the indentation control means disclosed in the patent document, there was an inconvenience in the means for measuring the injection pressure for each section of the indentation guide groove configured in the body of the air jet loom.

즉 경사가 바디에 끼워진 상태(통경)에서는 측정에 어려움이 있는 등의 단점이 있는 것이었다.That is, in the state where the inclination is fitted to the body (diameter), there was a disadvantage such as difficulty in measuring.
