    • The invention relates to devices and to methods for transporting preforms in the region of a blow-molding machine, in particular a sorting device (10) for transporting preforms (20) composed of a thermoplastic material in the region of a blow-molding machine for the blow-molding of containers, comprising a transport wheel (12), which has a plurality of accommodating recesses (18) for accommodating and conveying the preforms (20), which accommodating recesses are arranged on the circumference of the transport wheel in such a way that the accommodating recesses are distributed in the circumferential direction, a guide collar (16), which extends circumferentially around the transport wheel (12) in some regions in such a way that the guide collar is radially spaced apart from the transport wheel, wherein the preforms (20) are transported hanging between the transport wheel (12) and the guide collar (16) in the region of the sorting device (10), and a selecting unit for selectively removing an individual perform (20) transported in one of the accommodating recesses (18) of the transport wheel (12) in each case, wherein the selecting unit comprises a rotatably supported ejecting star (14) having a plurality of ejecting arms (31), which ejecting star, in the idle position, reaches into the circumferential region of the transport wheel (12) by means of a first ejecting arm (31) immediately adjacent to the guide collar (16) in the transport direction of the preforms (20), in such a way that the preforms (20) transported past the first ejecting arm (31) in the accommodating recesses (18) are secured against unintentionally falling out, wherein the ejecting star (14), in the event of a rotational motion, pushes an individual preform (20), which is to be removed, out of one of the accommodating recesses (18) of the transport wheel (12) by means of a second ejecting arm (32) following the first ejecting arm (31), and wherein, in a recurring manner after the preform (20) to be removed has been pushed out, the second ejecting arm (31) takes on the securing of the preforms (20) transported past the second ejecting arm against falling out of the accommodating recesses (18).
    • 本发明涉及用于在吹塑机的区域中输送预成型件的装置和方法,特别是用于在吹塑机的区域中输送由热塑性材料构成的预成型件(20)的分选装置(10),用于 包括输送轮(12)的容器吹塑,该输送轮(12)具有用于容纳和输送预成型件(20)的多个容纳凹部(18),该容纳凹部在输送轮的圆周上以这种方式布置 导向轴环(16),其在一些区域中围绕传送轮(12)周向延伸,使得导向轴环与传送轮径向间隔开,其中 所述预成型件(20)在所述分拣装置(10)的区域中被传送悬挂在所述传送轮(12)和所述引导环(16)之间,以及选择单元,用于选择性地移除 在每种情况下,在运送轮(12)的容纳凹部(18)之一中运送的单独履行(20),其中所述选择单元包括具有多个喷射臂(31)的可旋转地支撑的喷射星(14) 在空闲位置,通过在预成型件(20)的输送方向上与导向轴环(16)紧邻的第一排出臂(31)到达运送轮(12)的周向区域中, 以使得在所述容纳凹部(18)中经过所述第一推出臂(31)的所述预成型件(20)被固定而不会意外地脱落,其中,所述喷射星(14)在旋转运动的情况下, 借助于第一排出臂(31)之后的第二排出臂(32)将要移除的单个预成型件(20)推出运送轮(12)的一个容纳凹部(18) 并且其中,在所述预成型件(20)之后以重复的方式 已经被推出,第二排出臂(31)承受通过第二排出臂传送的预成型件(20)的固定,不会从容纳凹部(18)中脱出。
