    • An apparatus and method is disclosed for ejecting workpieces from machines, especially lidded containers from lid seamers, that have a forming station including a chuck element (110) and a forming roller and that have a positioning mechanism that advances to move the workpiece into engagement with the forming station. The apparatus and method utilize a resilient element (150) to exert an ejecting force. The resilient element is disposed on the chuck element (12) in a manner so that engagement of the workpiece (170) operates to compress, either by compression or deflection, the resilient element (160) so that it exerts a restorative force that ejects the workpiece. Where a lid seamer is used with a pull opener (e.g., pop top) lid, the contact with the resilient member occurs a location spaced from the opener and its connecting elements. The resilient element is preferably cup-shaped having a central panel and a longitudinally and radially outwardly projecting lip (160). A variety of constructions of the resilient element and manners of mounting to the chuck element and its associated spindle are described.
    • 公开了一种设备和方法,用于从机器,特别是来自盖子密封器的有盖容器中喷射工件,所述设备和方法具有包括卡盘元件(110)和成形辊的成形台,并且具有定位机构,该定位机构向前移动以使工件移动成与 成形站。 该设备和方法利用弹性元件(150)来施加弹出力。 弹性元件以这样的方式设置在卡盘元件(12)上,使得工件(170)的接合通过压缩或偏转来压缩弹性元件(160),以便施加弹性元件 工件。 在使用拉盖开启器(例如,弹出式顶盖)盖子的情况下,与开启器及其连接元件隔开的位置与弹性部件的接触发生。 弹性元件优选为杯形,具有中央面板和纵向且径向向外突出的唇部(160)。 描述了弹性元件的各种结构和安装到卡盘元件及其相关联的主轴的方式。
