歐洲專利案第EP 0 829 442 B1號描述一緯紗傳送裝置,其具有一固定底座及一固定鼓。藉一空心驅動轉軸驅動之一空心風車臂將複數個紗線繞組纏繞至該鼓上。該鼓分派給一運動系統,該運動系統適合於將該等纏繞繞組從該底座移動而抵靠該鼓之自由端。該等繞組係藉一相互間隔而隔開。 European Patent No. EP 0 829 442 B1 describes a weft transfer device, which has a fixed base and a fixed drum. A hollow windmill arm is driven by a hollow drive shaft to wind a plurality of yarn windings on the drum. The drum is assigned to a movement system adapted to move the winding windings from the base against the free end of the drum. The windings are separated by a mutual interval.
該運動系統係藉一組運動桿形成。該等運動桿從該鼓之圓柱形表面中的對應狹槽部份地且呈圓柱形地突出。該等運動桿藉各別之輻條(spokes)而連接至一中心轂,以大體上形成一鼓狀結構。該轂藉一滾子軸承之互連而連結至一襯套。該襯套配合至該驅動轉軸上之一偏心區段上。該襯套之軸線形成一相對於偏心軸線之固定傾斜角。 The movement system is formed by a group of movement rods. The moving rods project partially and cylindrically from corresponding slots in the cylindrical surface of the drum. The moving rods are connected to a central hub by respective spokes to form a drum-like structure substantially. The hub is connected to a bush by the interconnection of a roller bearing. The bush is fitted to an eccentric section of the drive shaft. The axis of the bush forms a fixed tilt angle relative to the eccentric axis.
該襯套之軸線與該驅動轉軸之軸線在鄰近該鼓自由端之一點處交叉。二旋轉方向上之相互間隔完全相同、或相差一極小量。 The axis of the bush and the axis of the drive shaft intersect at a point adjacent to the free end of the drum. The distance between the two rotation directions is exactly the same or differs by a very small amount.
在歐洲專利案第EP 0 968 949 B1號中描述一喂緯紗裝置,其具有一歪斜襯套,該歪斜襯套具有一第一及一第二襯套體。第一、半圓柱形襯套體連接至驅動轉軸以限定出轉軸之偏心區段。第二空心襯套體配置於該偏心區段上,且具有一相對於轉軸之軸線呈傾斜的外表面。 In European Patent No. EP 0 968 949 B1, a weft feeding device is described, which has a skewed bushing having a first and a second bushing body. The first, semi-cylindrical bushing body is connected to the drive shaft to define an eccentric section of the shaft.

The member used to move the winding includes a set of rods which are prevented from rotating relative to the drum, but partially and variably protrude above the periphery of the drum. These components are moved by the rotating shaft of the motor, and the components are arranged on the rotating shaft of the motor by a skew bushing and a rotating bearing. The skew bushing is formed by two hollow bodies, one of the hollow bodies can move relative to the other in the second rotation direction to a position rotated by 180°.
歐洲專利案第EP 0 244 511 B1號之標的係一用於緯紗傳送裝置之儲存裝置,其具有一鼓,緯紗線之繞組係藉由一馬達轉軸所啟動之配置而定位於該鼓之外表面上。該鼓設有一系列細長形開口,複數個桿件配置於該等開口中。該等桿件緊固至一托座上,該托座藉一軸承安裝於一偏心套筒上。該套筒安裝於該馬達轉軸上之一浮動接頭上。該套筒可相對於該馬達轉軸之軸線呈傾斜固定。 The subject of European Patent No. EP 0 244 511 B1 is a storage device for a weft yarn conveying device, which has a drum, and the winding of the weft yarn is positioned on the outer surface of the drum by a configuration activated by a motor shaft on. The drum is provided with a series of elongated openings, and a plurality of rods are arranged in the openings. The rods are fastened to a bracket, and the bracket is mounted on an eccentric sleeve by a bearing. The sleeve is installed on a floating joint on the motor shaft. The sleeve can be inclined and fixed relative to the axis of the motor shaft.
歐洲專利案第EP 0424 424 B1號中描述一接頭配置,其中此類套筒之圓柱形表面的軸承可從一中立位置相對於驅動轉軸在二側上調整。 European Patent No. EP 0424 424 B1 describes a joint arrangement in which the bearings of the cylindrical surface of such sleeves can be adjusted on two sides from a neutral position relative to the drive shaft.
在歐洲專利案第EP 0 643 004 B1號中描述一襯套,其可旋轉且依相對於一驅動轉軸之一角度配置。 In European Patent No. EP 0 643 004 B1, a bush is described, which is rotatable and arranged at an angle relative to a driving shaft.
由歐洲專利案第EP 1 796 994 B1號已知一用於編織機之具有一機殼的紗線傳送裝置。該機殼以可旋轉式支持一驅動轉軸,且支持一靜止儲存體。該儲存體具有一支持桿籠(support rod cage)及一在內側之分離桿籠。該分離桿籠具有一軸線,該軸線相對於該驅動轉軸之軸線呈歪斜且偏

From European Patent No.
紗線繞組分離地配置於其上之窄小儲存體僅可固持有限的紗長度。所需之紗量可依據待在圓編織機上生產之產品而大幅變化。 The narrow storage body on which the yarn windings are separately arranged can only hold a limited yarn length. The amount of yarn required can vary greatly depending on the product to be produced on the circular knitting machine.
本發明之目的係發展一種可藉窄小儲存體來固持大量紗之喂紗裝置。該目的亦在發展一種具有喂紗裝置的系統,其中該喂紗裝置可藉簡單構件作修飾。 The purpose of the present invention is to develop a yarn feeding device that can hold a large amount of yarn by means of a narrow storage body. The purpose is also to develop a system with a yarn feeding device, wherein the yarn feeding device can be modified by simple components.
該目的係藉以下描述之一種喂紗裝置及具有喂紗裝置的系統之特點達成。 This objective is achieved by the characteristics of a yarn feeding device and a system with yarn feeding device described below.
依據本發明之一種將一紗線喂至一紡織機器的喂紗裝置設有一機殼及一儲存裝置,該紗線係藉該紡織機器而從該儲存裝置拉取。該喂紗裝置包括一用於將該紗線纏繞至該儲存裝置上之纏繞元件、及一用於驅動該纏繞元件之具有軸線的可驅動轉軸。該喂紗裝置包括一用於將該儲存裝置固定至該機殼上之磁鐵配置。該儲存裝置包括一儲存體及一搖晃體(wobble body)。 A yarn feeding device for feeding a yarn to a textile machine according to the present invention is provided with a housing and a storage device, and the yarn is drawn from the storage device by the textile machine. The yarn feeding device includes a winding element for winding the yarn onto the storage device, and a driveable rotating shaft with an axis for driving the winding element. The yarn feeding device includes a magnet arrangement for fixing the storage device to the casing. The storage device includes a storage body and a wobble body.
該搖晃體連同一搖晃軸承單元形成該喂紗裝置之一搖晃單元。該搖晃體具有一襯套、及連接至該襯套之複數個輸送元件。該搖晃軸承單元包括一配置於該轉軸上之軸承襯套及至少一個配置於該軸承襯套上用於支持該襯套之軸承,該軸承襯套具有一搖晃區段,該搖晃區段具有一歪斜圓柱形外罩表面,該歪斜圓柱形外罩表面之軸線相對於該轉軸之該軸線呈歪斜。 The shaking body and the shaking bearing unit form a shaking unit of the yarn feeding device. The shaking body has a bush and a plurality of conveying elements connected to the bush. The rocking bearing unit includes a bearing bush arranged on the rotating shaft and at least one bearing arranged on the bearing bush for supporting the bush, the bearing bush having a shaking section, the shaking section having a The surface of the skewed cylindrical housing is skewed with respect to the axis of the rotating shaft.
該搖晃單元設計於一分離區段中,以輸送複數個紗繞組,此 等紗繞組纏繞至該儲存體上使該等紗繞組之間具有一間隔(spacing)。在此,該等輸送元件可藉該搖晃軸承單元而在該儲存體之一包絡表面(enveloping surface)上方周期地運動通過該儲存體之複數個細長形開口。藉由該等輸送元件,該等紗繞組將在彼此之間間隔下朝該儲存體之一拉取端的方向輸送。 The shaking unit is designed in a separate section to transport multiple yarn windings. The yarn windings are wound on the storage body so that there is a spacing between the yarn windings. Here, the conveying elements can periodically move over an enveloping surface of the storage body through the plurality of elongated openings of the storage body by the shaking bearing unit. By means of the conveying elements, the yarn windings will be conveyed in the direction of one of the pulling ends of the storage body while being spaced apart from each other.
該儲存體之該包絡表面具有一通過該等開口之多邊形周邊。 The envelope surface of the storage body has a polygonal periphery passing through the openings.
該儲存體之該拉取端係該儲存體之外緣,該紗線係在其上方朝該紡織機器被拉取。 The pulling end of the storage body is the outer edge of the storage body, and the yarn is pulled upward toward the textile machine.
安裝於該搖晃軸承單元上之該搖晃體在該轉軸旋轉期間實施一搖晃運動,其中該等輸送元件在該儲存體之該包絡表面上方周期地在該分離區段中前後運動。在此,纏繞至該儲存裝置之該儲存體上的紗繞組係在彼此的一特定間隔下抬起與放下。該搖晃體之搖晃運動造成該等紗繞組之分離。 The shaking body mounted on the shaking bearing unit implements a shaking movement during the rotation of the rotating shaft, wherein the conveying elements periodically move back and forth in the separation section above the envelope surface of the storage body. Here, the yarn windings wound on the storage body of the storage device are raised and lowered at a specific interval from each other. The shaking motion of the shaking body causes the separation of the yarn windings.
該搖晃單元設計於一積聚區段(accumulation section)中,以將纏繞至該儲存體上之該等紗繞組朝該儲存體之該拉取端的方向推動而在此等紗繞組之間無間隔,該積聚區段係與該分離區段鄰接且配置於該儲存體之一拉取高度(draw-off height)上方,該拉取高度係在該紗線從該儲存體拉取所在之該儲存體進程上方(over the course)的高度。該拉取高度配置於該儲存體之拉取端上方。該拉取高度可譬如依據紗線之品質而變化。 The shaking unit is designed in an accumulation section to push the yarn windings wound on the storage body in the direction of the pulling end of the storage body without a gap between the yarn windings, The accumulation section is adjacent to the separation section and is arranged above a draw-off height of the storage body, and the draw-off height is at the storage body where the yarn is drawn from the storage body The height above the course. The drawing height is arranged above the drawing end of the storage body. The pulling height can vary, for example, according to the quality of the yarn.
在該積聚區段之區域中大體上無分離。反而,纏繞至該儲存體上且來自該分離區段之紗繞組係彼此推抵、亦即接觸。該等紗繞組被先前紗繞組進一步推動。 There is substantially no separation in the area of the accumulation zone. Instead, the yarn windings wound on the storage body and coming from the separated section push against each other, that is, contact each other. The yarn windings are further pushed by the previous yarn windings.
在該喂紗裝置具有一裝料高度感測器之一具體實施例中,從該儲存體之移開端(take-off end)限定出該積聚區段的該拉取高度係位在該裝料高度感測器之一量測平面高度處。 In a specific embodiment of the yarn feeding device having a loading height sensor, the take-off end (take-off end) defining the accumulation section from the storage body is positioned at the loading height sensor. One of the material height sensors measures the height of the plane.
在一範例中,裝料高度感測器設計成一回彈元件,其在該儲存體之下方區域中配置於該儲存體上。當一特定量紗線配置於該裝料高度感測器上時,將觸發該裝料高度感測器。該量測平面譬如定義為在該裝料高度感測器被觸發前最後一個紗線繞組之高度處垂直於該轉軸之軸線的平面。 In one example, the charging height sensor is designed as a resilient element, which is disposed on the storage body in the lower area of the storage body. When a specific amount of yarn is arranged on the charging height sensor, the charging height sensor will be triggered. The measurement plane is, for example, defined as the plane perpendicular to the axis of the rotating shaft at the height of the last yarn winding before the charging height sensor is triggered.
在另一範例中,該裝料高度感測器設計成一光學感測器。例如,與該轉軸之軸線垂直的平面定義為該感測器所探測之量測平面。 In another example, the charging height sensor is designed as an optical sensor. For example, the plane perpendicular to the axis of the rotating shaft is defined as the measurement plane detected by the sensor.
在一具體實施例中,該積聚區段延伸跨越一從2毫米到10毫米之該儲存體的高度。在一具體實施例中,該積聚區段延伸跨越一從3毫米到7毫米之該儲存體的高度。 In a specific embodiment, the accumulation section extends across a height of the storage body from 2 mm to 10 mm. In a specific embodiment, the accumulation section extends across a height of the storage body from 3 mm to 7 mm.
選擇該積聚區段之長度使得該積聚區段中之10到50個紗繞組彼此鄰接。這意謂積聚區段S2之長度與一10到50個鄰接紗繞組的區段相當。特定地,該積聚區段之長度與15到40個鄰接紗繞組相當。 The length of the accumulation section is selected so that 10 to 50 yarn windings in the accumulation section are adjacent to each other. This means that the length of the accumulation section S2 is equivalent to a section of 10 to 50 adjacent yarn windings. Specifically, the length of the accumulation section is equivalent to 15 to 40 adjacent yarn windings.
在一具體實施例中,該搖晃單元具有一軸承襯套,其中該軸承襯套之搖晃區段的歪斜圓柱形外罩表面之一軸線係與該轉軸之軸線在位於該儲存體之拉取端區域中、亦即該拉取高度上或下方的一點處交叉。 In a specific embodiment, the shaking unit has a bearing bush, wherein an axis of the skewed cylindrical housing surface of the shaking section of the bearing bush and the axis of the rotating shaft are located at the pull-out end region of the storage body Middle, that is, cross at a point above or below the pulling height.
在一變型中,該等輸送元件係沿該積聚區段大體上配置於該儲存體之包絡表面內。在該等輸送元件沿該積聚區段延伸之一具體實施例中,該等輸送元件係沿該積聚區段朝內斜。在該等輸送元件沿該積聚區段延伸之一具體實施例中,該等輸送元件配置成可運動達該儲存體之該包絡表面。這意謂該等輸送元件在搖晃運動期間於該積聚區段之區域中與該等紗繞組短暫接觸。在此,該等紗繞組略微抬起。這確保鄰接之紗繞組在該積聚區段中位移而不致重疊。 In a variant, the conveying elements are arranged substantially within the envelope surface of the storage body along the accumulation section. In a specific embodiment of the conveying elements extending along the accumulation section, the conveying elements are inclined inwardly along the accumulation section. In an embodiment of the conveying elements extending along the accumulation section, the conveying elements are configured to be movable to the envelope surface of the storage body. This means that the conveying elements are in brief contact with the yarn windings in the area of the accumulation section during the shaking movement. Here, the yarn windings are slightly lifted. This ensures that adjacent yarn windings are displaced in the accumulation section without overlapping.
在又一變型中,該等輸送元件大體上沿該分離區段延伸。 In yet another variant, the conveying elements extend substantially along the separation section.
在一具體實施例中,該搖晃單元包括一軸承襯套,其中該軸 承襯套之搖晃區段的圓柱形外罩表面之軸線係與該轉軸之軸線在位於該分離區段與該積聚區段之間之過渡區域中的一點處交叉。 In a specific embodiment, the shaking unit includes a bearing bush, wherein the shaft The axis of the cylindrical outer cover surface of the shaking section of the bearing sleeve intersects the axis of the rotating shaft at a point in the transition area between the separation section and the accumulation section.
一種系統,包括一喂紗裝置及一更換單元。 A system includes a yarn feeding device and a replacement unit.
該更換單元之搖晃單元、或搖晃單元的元件設計成用於一分離區段,該分離區段延伸達該拉取高度。該更換單元之該分離區段延伸跨越該喂紗裝置之該分離區段及該積聚區段。當使用該更換單元時,不設置一積聚區段。 The shaking unit or the components of the shaking unit of the replacement unit are designed to be used in a separation section which extends to the drawing height. The separation section of the replacement unit extends across the separation section and the accumulation section of the yarn feeding device. When using this replacement unit, no accumulation section is provided.
在一具體實施例中,其中該喂紗裝置包括複數個輸送元件,其沿該積聚區段大體上配置於該儲存體之包絡表面內側、或僅沿該分離區段延伸,該更換單元包括複數個輸送元件。該更換單元之該等輸送元件係沿該分離區段延伸。該等輸送元件可在該儲存體之該包絡表面上方、在該分離區段中運動通過該等開口。在一具體實施例中,該更換單元包括該等輸送元件。在一具體實施例中,該更換單元包括一搖晃體結合該等輸送元件。 In a specific embodiment, the yarn feeding device includes a plurality of conveying elements, which are arranged substantially inside the envelope surface of the storage body along the accumulation section, or extend only along the separation section, and the replacement unit includes a plurality of A delivery element. The conveying elements of the replacement unit extend along the separation section. The conveying elements can move through the openings in the separation section above the envelope surface of the storage body. In a specific embodiment, the replacement unit includes the conveying elements. In a specific embodiment, the replacement unit includes a shaking body combined with the conveying elements.
在該喂紗裝置具有一軸承襯套、且其中該搖晃區段之歪斜圓柱形外罩表面的軸線與該轉軸之軸線在位於該分離區段與該積聚區段之間之過渡處的一點處交叉之一具體實施例中,該更換單元包括另一軸承襯套。 The yarn feeding device has a bearing bush, and the axis of the skewed cylindrical outer cover surface of the shaking section and the axis of the rotating shaft cross at a point located at the transition between the separating section and the accumulating section In a specific embodiment, the replacement unit includes another bearing bush.
在一變型中,該更換單元包括一軸承襯套,該搖晃區段之歪斜圓柱形外罩表面與該軸線在位於該拉取高度上方之一點處交叉。在此,譬如歪斜位置、亦即該歪斜圓柱形外罩表面之軸線與該轉軸之軸線間的角度係與該喂紗裝置之對應者不同。 In a variant, the replacement unit includes a bearing bush, and the skewed cylindrical housing surface of the shaking section intersects the axis at a point located above the drawing height. Here, for example, the skew position, that is, the angle between the axis of the skewed cylindrical cover surface and the axis of the rotating shaft, is different from the corresponding one of the yarn feeding device.
在另一變型中,該交叉點之位置改變。 In another variant, the position of the intersection is changed.
在一範例中,該更換單元之該軸承襯套具有該搖晃區段之該歪斜圓形外罩表面的一軸線,其與該轉軸之軸線在位於該儲存體之拉取高度上或下方的一點處交叉。 In an example, the bearing bush of the replacement unit has an axis of the skewed circular housing surface of the shaking section, and the axis of the shaft and the axis of the shaft are located at a point above or below the drawing height of the storage body cross.
在一具體實施例中,該更換單元僅包括該軸承襯套。 In a specific embodiment, the replacement unit only includes the bearing bush.
