    • Stacks of generally dish-shaped, nested plastic articles are gripped and transferred from elevated, horizontally adjacent chutes comprising circumferentially disposed, axially extending supports, which are open at both ends to permit articles to be both fed thereto and removed axially therefrom, to a conveyor disposed at a lower level. A transfer arm, mounting stack gripping receivers, which pivot on the transfer arm, is swung in an arcuate path and the receivers are moved relative to the transfer arm, responsive to swinging movement of the transfer arm, such that the receivers travel from a first position, horizontally axially aligned with said chutes and axially intermeshed with the supports, in a path having a first axially linear increment, then a downward arc to rotate said stacks substantially 90.degree., and finally a vertically linear path to deposit the stacks on the conveyor. The receivers are radially contracted to peripherally grip stacks of articles in the chutes when the receivers are in the first position, and are radially expanded to peripherally release the stacks when the receivers have moved the stacks to the conveyor.
    • 大体上盘形的嵌套塑料制品的堆叠被夹紧并从包括周向设置的轴向延伸的支撑件的升高的水平相邻的滑槽传送,所述两个端部在两端敞开,以允许制品两者都被馈送到其中并从其中轴向移除到输送机 处于较低级别。 在传送臂上枢转的传送臂,安装堆叠夹持接收器以弧形路径摆动,并且响应于传送臂的摆动运动,接收器相对于传送臂移动,使得接收器从第一 位置,与所述滑槽水平轴向对准,并且在具有第一轴向线性增量的路径中与支撑件轴向啮合,然后是向下的弧以使所述堆叠大致旋转90°,最后是垂直线性路径以将堆叠沉积在输送机 。 当接收器处于第一位置时,接收器被径向收缩以周向地夹持在斜槽中的物品堆叠,并且当接收器已经将堆叠移动到输送机时,接收器被径向收缩以沿着方向夹紧在滑槽中的物品堆叠。

    • A plug assist drive assembly for driving plug assists in a thermoforming apparatus includes a single centrally located roller screw assembly enclosed in a housing and driving a third platen mounting the plug assist with a group of guide-drive bars connected to a drive platen which is driven by the roller screw nut. The roller screw assembly is removable by removing screws holding the nut to one hub adapter, the screws accessed through an opening in the housing normally covered with a plate.
