    • Opened fibers are supplied into a rotor in high rotation, and a fiber bundle collected at a fiber-collecting section of the rotor is drawn as yarn from a yarn drawing passage provided on the open side of the rotor. A rotary assembly which is actively driven separately from the rotor is provided coaxially in the rotor. The rotary assembly has at least part thereof facing the vicinity of the fiber-collecting section and another part shaped to face a first end of the yarn drawing passage. The rotary assembly is provided with a yarn passage for guiding a fiber bundle to a position opposite the yarn drawing passage from the vicinity of the fiber-collecting section. A twist propagation preventing portion is provided in that end of the yarn passage that lies on the fiber-collecting section side. The rotation of the fiber bundle is suppressed by the twist propagation preventing portion, stopping the twisting. At the time the fiber bundle is twisted, tension is applied to the fibers so that the fibers are twisted while being stretched.
    • 将开放的纤维高转矩地供给到转子中,将收集在转子的纤维收集部的纤维束从设置在转子的开口侧的纱线抽出通道拉出。 与转子分开主动驱动的旋转组件同轴地设置在转子中。 旋转组件的至少一部分面向纤维集合部分附近,另一部分成形为面对牵引通道的第一端。 旋转组件设置有纱线通道,用于将纤维束从纤维收集部分附近引导到与纱线抽出通道相对的位置。 在该纱线通道的位于纤维收集部侧的一端设有扭转传播防止部。 通过扭转传播阻止部分抑制纤维束的旋转,停止扭转。 在纤维束被扭曲的同时,对纤维施加张力,使得纤维被拉伸时被扭曲。

    • A fiber transporting apparatus for a rotor type open end fine spinning machine is provided that may reduce an amount of effective fiber discharged from a burling opening portion without degrading yarn quality of the spun yarn. Fiber opened by a combing roller (11) is fed into a rotor through a fiber transporting channel (13) leading from a circumferential surface of the combing roller (11) to a predetermined position of the rotor (6) in accordance with a negative pressure degree within the rotor (6). After debris is removed from the opened fiber by a burling opening portion (12), the opened fiber is moved together with an air flow directed from a downstream side of the burling opening portion (12) in a rotational direction of the combing roller (11) toward an inlet (13a) of the fiber transporting channel (13). A portion of the air flow directed toward the inlet (13a) of the fiber transporting channel (13) is led from a suction passage (17) to a negative pressure source (5) along the way, and the flow rate of air introduced from an outlet (13b) of the fiber transporting channel (13) to a rotor (6) is reduced. Accordingly, even if the flow rate of the air directed from the burling opening portion (12) to the fiber transporting channel (13) is increased, the flow rate of the air introduced into the rotor (6) is kept at a suitable level.
    • 提供了一种用于转子式开口微细纺纱机的纤维输送装置,其可以减少从打孔部排出的有效纤维的量,而不会降低纺纱的纱线质量。 由精梳辊(11)打开的纤维通过从精梳辊(11)的圆周表面引导到转子(6)的预定位置的纤维传送通道(13),根据负压 转子内的角度(6)。 在打开的开口部分(12)从打开的纤维上除去碎片之后,打开的纤维沿着梳理开口部分(12)的下游侧沿着精梳辊(11)的旋转方向的空气流一起移动 )朝向光纤传输通道(13)的入口(13a)。 朝向纤维输送通道(13)的入口(13a)的空气流的一部分沿着通道从吸入通道(17)被引导到负压源(5),并且从 纤维输送通道(13)到转子(6)的出口(13b)减少。 因此,即使从起泡开口部(12)向纤维输送通道(13)引导的空气的流量增加,导入转子(6)的空气的流量也保持在合适的水平。

    • A rotor type open-end spinning machine of a structure in which fibers moving slidingly on an inner wall surface of an outer rotor (2) are prevented from falling at a location where a fiber bundle is being stripped off from a fiber collecting/bundling section (7) while being twisted concurrently. An inner rotor (5) is disposed within the outer rotor (2) and positively driven independently of the latter. A delivery passage (20) is formed in the inner rotor (5) for guiding a fiber bundle (F) bundled in a fiber collecting/bundling groove (7) to a yarn withdrawing passage (14). An annular negative-pressure chamber (6) is formed radially outward of the fiber collecting/bundling groove (7) of the outer rotor (2) with air discharge holes (9) being provided for communicating the negative-pressure chamber (6) to the exterior of the outer rotor (2). A plurality of air vent through-holes (8) are formed each at a location close to the delivery passage (20) with a predetermined distance therebetween in a circumferential direction for communicating an inner space defined in the outer rotor (2) to the negative-pressure chamber (6). A shield member (21) is formed on the inner rotor (5) for intercepting the air vent through-holes (8) from the negative-pressure chamber (6) except for those located in a predetermined region opposite the delivery passage (20).
    • 一种转子式开放式纺丝机,其特征在于,防止在外转子(2)的内壁面上滑动的纤维在纤维束从纤维收集/捆扎部剥离的位置处落下 (7)同时扭曲。 内转子(5)设置在外转子(2)内,并且独立于后转子(2)。 在内转子(5)中形成有用于将收集在纤维集合槽(7)中的纤维束(F)引导到纱线抽出通道(14)的输送通道(20)。 在外转子(2)的纤维收集/收集槽(7)的径向外侧形成环状的负压室(6),其中设有用于使负压室(6)连通的空气排出孔 外转子(2)的外部。 多个排气通孔(8)分别形成在靠近输送通道(20)的位置上,在圆周方向上以预定的距离,以将外转子(2)中限定的内部空间连接到负 压力室(6)。 除了位于与输送通道(20)相对的预定区域中的位置之外,在内转子(5)上形成用于从负压室(6)截取通气孔(8)的屏蔽构件(21) 。
