Description
本發明係關於一種送紗輪的結構，尤指一種用於圓編織機的送紗輪之改良結構。 The present invention relates to a structure of a yarn feeding wheel, and more particularly to an improved structure of a yarn feeding wheel for a circular knitting machine.
過去送紗輪大體上分為(1)光滑送紗表面之送紗周面；(2)柵欄式送紗周面及(3)附膠圈之送紗周面。光滑送紗周面雖構造簡單，但紗線全面繞設在光滑送紗外周之摩擦送紗周面時，遇有纏紗情況時，操作員便直接以刀具割除纏紗，因而一不小心便極易割傷光滑送紗周面而使送紗輪周面構造受損，其使用壽命較短；附膠圈之送紗輪，其構造雖也簡單，但生命週期也不長，受紗線之磨擦作用約3-6個月要更新乙次；至柵欄式送紗輪使用週期較長，但其構造較為複雜，在裝配上每一根鐵棒均須一一定位才能固定裝配完成，故裝配上費工、費時，且其輪體與鐵棒間之組配不易精準，快速運轉時，屢有恍動情形發生，影響送紗品質，而有待改善。 In the past, the yarn feeding roller was roughly divided into (1) the yarn feeding peripheral surface of the smooth yarn feeding surface; (2) the fence type yarn feeding peripheral surface and (3) the rubber feeding circumferential surface of the rubberized ring. Although the smooth yarn feeding surface is simple in structure, when the yarn is completely wound around the peripheral surface of the friction feeding yarn of the smooth yarn feeding, when the yarn is wound, the operator directly cuts the yarn by the cutter, so that carelessly It is easy to cut and smooth the surface of the yarn to make the peripheral surface of the yarn feeding wheel damaged, and its service life is short. The yarn feeding wheel with a rubber ring is simple in structure, but the life cycle is not long. The friction effect is updated about 3-6 months. The use of the fence type yarn feeding wheel is longer, but the structure is more complicated. Each iron rod must be positioned one by one to be assembled and assembled. The assembly is labor-intensive and time-consuming, and the combination between the wheel body and the iron bar is not easy to be precise. When the machine is running fast, there are repeated turbulences that affect the quality of the yarn to be fed, and it needs to be improved.

In normal operation, the yarn feeding wheel is rotated accurately without any swaying, and the breaking of the irregular yarn feeding tension is unstable and the yarn feeding needs to be frequently changed. The problem of the rubber ring on the wheel, combining the advantages of the irregular yarn feeding with the stability advantages of the active yarn feeding technology, constitutes a dual-purpose yarn feeding device with a novel positive quantitative yarn feeding and an irregular (negative) variable yarn feeding.
本發明的又一目的在於提供一種送紗輪之改良構造，在正常運轉時，可自然散熱通風，且可將聚積在送紗輪上之棉絮自行吹淨，因此本 發明可自行清理送紗輪上之棉絮並可延長送紗輪之使用壽命者。 Another object of the present invention is to provide an improved structure of a yarn feeding wheel, which can naturally dissipate and ventilate during normal operation, and can directly blow the cotton wool accumulated on the yarn feeding wheel, so The invention can clean the batt on the yarn feeding wheel and extend the service life of the yarn feeding wheel.

When the yarn feeding wheel 1A rotates, the upper and lower sides are rotated. The wheel covers 10A, 30A rotate accordingly and are ventilated by the oblique ventilation partitions 17A, 35A, and the convection of the hot air flow is performed from the top to the bottom or from the bottom up by the vents 15A, 33A. Natural heat dissipation and ventilation, as such, the conductive plate 40A in the second embodiment can be omitted from the blade 413A, or the conductive plate 40 of the first embodiment can be used instead.
該導電板40A之導電彈片43A一端連接於導電板40A的中心孔42A邊際處，且中心孔42A及導電板本體41A上圓形孔412A對應套入中心軸桿50及下輪蓋30A之凸柱312A，而使導電彈片43A穿經下輪蓋30A之通槽313A與中心軸桿50發生電的接觸。 One end of the conductive elastic piece 43A of the conductive plate 40A is connected to the edge of the central hole 42A of the conductive plate 40A, and the central hole 42A and the circular hole 412A of the conductive plate body 41A are correspondingly inserted into the convex column of the central shaft 50 and the lower wheel cover 30A. 312A, the conductive elastic piece 43A is electrically contacted with the central shaft 50 through the through groove 313A of the lower wheel cover 30A.
導電板本體41A外圍所設突出之導電片411A，於套入安裝後，導電片411A剛好接觸送紗套筒20之內壁21發生電的接觸，使因紗線Y與送紗套筒20A之凸部23A磨擦所產生之靜電，可以經由導電片411A、導電板40A本體41A、導電彈片43A、中心軸桿50導引至架體100接地，而可消除靜電，使紗線Y在送紗時不致因靜電吸附現象而使紗線糾纏成團，以獲得與第一實施例相同之效果者。 The protruding conductive strip 411A is disposed on the periphery of the conductive plate body 41A. After the sleeve is mounted, the conductive sheet 411A just contacts the inner wall 21 of the yarn feeding sleeve 20 to make electrical contact, so that the yarn Y and the yarn feeding sleeve 20A are The static electricity generated by the friction of the convex portion 23A can be guided to the ground of the frame 100 via the conductive sheet 411A, the main body 41A of the conductive plate 40A, the conductive elastic piece 43A, and the central shaft 50, thereby eliminating static electricity and causing the yarn Y to be fed. The yarn is not entangled by the electrostatic adsorption phenomenon to obtain the same effects as those of the first embodiment.
請參閱第12至14圖，其係顯示本發明所提供之送紗輪之改良構造之第三實施例，本實施例中送紗輪1B主要元件與第二實施例相同，故標以相同符號並省略其說明。 Referring to Figures 12 to 14, there is shown a third embodiment of the improved construction of the yarn feeding wheel provided by the present invention. In this embodiment, the main components of the yarn feeding roller 1B are the same as those of the second embodiment, and therefore the same symbols are used. The description is omitted.
第三實施例之送紗輪1B與第二實施例主要差異之處在於送紗輪1B的送紗套筒20B其送紗面24B設成一光滑面，並在光滑面上設至少一縱向溝241B以便纏紗時，可利用刀具沿著縱向溝241B割開，否則刀具直接往上 一拉，送紗輪1B很容易被刀具刮出刀痕，而使送紗輪1B損壞。 The main difference between the yarn feeding roller 1B of the third embodiment and the second embodiment is that the yarn feeding sleeve 20B of the yarn feeding roller 1B has its yarn feeding surface 24B set to a smooth surface, and at least one longitudinal groove is provided on the smooth surface. 241B can be used to wrap the yarn along the longitudinal groove 241B, otherwise the tool will go straight up. With one pull, the yarn feed roller 1B is easily scratched by the cutter, and the yarn feed roller 1B is damaged.
上、下輪蓋10B、30B對應送紗套筒20B分別設有一較窄的環狀槽131B、321B，以供送紗套筒20B可如第14圖中所示以兩端分別崁合在上、下輪蓋10B、30B之環狀槽131B、321B之間。 The upper and lower wheel covers 10B, 30B are respectively provided with a narrow annular groove 131B, 321B corresponding to the yarn feeding sleeve 20B, so that the yarn feeding sleeve 20B can be respectively coupled at both ends as shown in FIG. Between the annular grooves 131B and 321B of the lower wheel covers 10B and 30B.
請參閱第15至17圖，其係顯示本發明所提供之送紗輪之改良構造之第四實施例，本實施例中送紗輪1C主要元件與第二實施例相同，故標以相同符號並省略其相關說明。 Referring to Figures 15 to 17, there is shown a fourth embodiment of the improved construction of the yarn feed pulley provided by the present invention. In this embodiment, the main components of the yarn feed pulley 1C are the same as those of the second embodiment, and therefore the same symbols are used. The relevant description is omitted.
第四實施例之送紗輪1C與第二實施例差異處在於將第二實施例中導電片411A改為第四實施例中往一側各延伸出葉片413C，使導電板40C之外周設有多數個葉片413C，第四實施例發生電接觸的結構與第二實施例相同。 The difference between the yarn feeding roller 1C of the fourth embodiment and the second embodiment is that the conductive sheet 411A of the second embodiment is changed to the blade 413C extending to one side in the fourth embodiment, so that the outer periphery of the conductive plate 40C is provided. The structure in which the plurality of blades 413C and the fourth embodiment are electrically contacted is the same as that of the second embodiment.
再者，將第四實施例中的送紗套筒20C與第二實施例中的送紗套筒20差異在於其送紗面的弧形凹部22C與多角形凸角部25C之間的凹凸部差異較小，將送紗面之凹凸部差距做成較為圓滑之形狀，即凹凸部間之差距較小，介乎第二、三實施例之間，且即一體成型為多角形弧邊凹部22C與多角形凸角部25C間之高度差距較小之送紗套筒20C，該多角形凸角部25C宜另行硬化處理，如陽極硬化處理，令其使用壽命週期更長，而形成送紗輪之儲紗段，對現代新功能紗非常適用，即凸角部25C高度較小之角部之對紗線張力(向外)較為緩和，因而送紗、出紗較為順滑而相當實用。 Further, the yarn feeding sleeve 20C in the fourth embodiment is different from the yarn feeding sleeve 20 in the second embodiment in the uneven portion between the arcuate concave portion 22C of the yarn feeding surface and the polygonal convex portion 25C. The difference is small, and the gap between the concave and convex portions of the yarn feeding surface is made into a relatively round shape, that is, the difference between the concave and convex portions is small, between the second and third embodiments, and integrally formed into a polygonal arc edge concave portion 22C. The yarn feeding sleeve 20C having a small difference in height from the polygonal corner portion 25C, the polygonal convex portion 25C should be separately hardened, such as an anode hardening treatment, so that the service life cycle is longer, and the yarn feeding wheel is formed. The yarn storage section is very suitable for modern new functional yarns, that is, the yarn tension (outward) of the corner portion having a small height of the convex portion 25C is moderated, so that the yarn feeding and the yarn discharging are smooth and practical.
縱向凹凸部並不限於本實施例中圖中所示結構，即凡符合縱向凹凸部的凹部為一縱向凹形長弧面形狀，而凸部為一縱向極小弧面形狀定義之結構均可為本實施例中弧形凹部22C與凸角部25C。 The longitudinal concavo-convex portion is not limited to the structure shown in the figure in the embodiment, that is, the concave portion conforming to the longitudinal concavo-convex portion is a longitudinal concave long curved surface shape, and the structure in which the convex portion is defined by a longitudinal extremely small arc surface shape may be In the present embodiment, the arcuate recess 22C and the lobe 25C.
該上輪蓋10C對應送紗套筒20C設有環狀槽131C並對應多角形的凸角部25C設有崁合槽132C，而下輪蓋30C對應送紗套筒20C的凸角部25C設有一較寬的環狀槽321C，以供送紗套筒20C可如第17圖中所示以兩端分別崁合在上輪蓋10C之環狀槽131C、崁合槽132C與下輪蓋30C較寬之環狀槽321C之間。 The upper wheel cover 10C is provided with an annular groove 131C corresponding to the yarn feeding sleeve 20C, and is provided with a kneading groove 132C corresponding to the polygonal corner portion 25C, and the lower wheel cover 30C is provided corresponding to the convex portion 25C of the yarn feeding sleeve 20C. There is a wide annular groove 321C for the yarn feeding sleeve 20C to be coupled to the annular groove 131C, the coupling groove 132C and the lower wheel cover 30C of the upper wheel cover 10C at both ends as shown in FIG. Between the wider annular grooves 321C.
請參閱第18、18A圖，其係顯示本發明所提供之送紗輪之改良構造之 第五實施例，本實施例中送紗輪1D主要元件與前述第四實施例實施例相同，故標以相同符號並省略其說明。 Please refer to Figures 18 and 18A, which show an improved construction of the yarn feeding wheel provided by the present invention. In the fifth embodiment, the main components of the yarn feed roller 1D in this embodiment are the same as those in the fourth embodiment, and the same reference numerals will be given thereto, and the description thereof will be omitted.
第五實施例之送紗輪1D與前述實施例所不同之處僅在於將前述實施例之凹凸部間之高度形狀變化差距更趨於緩和之凹弧形邊多角形外周，即其凹部22D與凸角部25D間之高度差距又更小且凹部22D弧度又更接近圓形之送紗套筒20D(如第18圖所示)，非常適合新功能紗之送紗運轉。 The yarn feeding wheel 1D of the fifth embodiment differs from the foregoing embodiment only in that the difference in the height shape change between the uneven portions of the foregoing embodiment is more moderated by the concave curved polygonal outer periphery, that is, the concave portion 22D thereof The height difference between the corner portions 25D is smaller and the concave portion 22D is closer to the circular yarn feeding sleeve 20D (as shown in Fig. 18), which is very suitable for the yarn feeding operation of the new functional yarn.
該上輪蓋10D對應送紗套筒20D設有環狀槽131D並對應多角形的凸角部25D設有崁合槽132D，而下輪蓋30D對應送紗套筒20D的凸角部25D設有一較寬的環狀槽321D，以供送紗套筒20D可以兩端分別崁合在上輪蓋10D之環狀槽131D、崁合槽132D與下輪蓋30D較寬之環狀槽321D之間。 The upper wheel cover 10D is provided with an annular groove 131D corresponding to the yarn feeding sleeve 20D, and a convex groove portion 132D is provided corresponding to the polygonal convex portion 25D, and the lower wheel cover 30D is provided corresponding to the convex portion 25D of the yarn feeding sleeve 20D. There is a wide annular groove 321D for the yarn feeding sleeve 20D to be coupled to the annular groove 131D of the upper wheel cover 10D, the groove 132D of the upper wheel cover 10D and the annular groove 321D of the lower wheel cover 30D. between.
送紗套筒20D係用鋁材以鋁擠型方式一體成型長管後，再行切割成所需要之尺寸長度所構成，當然亦可用鋁材或鋁合金一體成型為單獨之送紗套筒20D，以獲得與前述實施例相同之效果者。 The yarn feeding sleeve 20D is formed by integrally forming a long tube by aluminum extrusion, and then cutting into a required length of the length. Of course, aluminum or aluminum alloy can be integrally formed into a separate yarn feeding sleeve 20D. To obtain the same effects as the foregoing embodiments.
綜上所述，凡此說明係針對本發明之可行實施例之具體說明，惟該實施例並非用以限制本發明之專利範圍，凡未脫離本發明技術精神所為之等效實施或變更，均應包含於本案之專利範圍中。 In the above, the description is directed to the specific embodiments of the present invention, and the embodiments are not intended to limit the scope of the invention, and all equivalents or modifications may be made without departing from the spirit of the invention.
