Vacuum die mount
摘要：
A method and apparatus for mounting a die (62), par­ticularly a rigid cutting die, on a die cylinder (22) includes having a bubble (116) along a seal (76) on the die to bridge any gaps between the die (62) and the die cylinder (22) when the die is initially positioned on the die cylinder (22). This bubble seal (76) enables a vacuum to be applied between the initially positioned die (62) and the die cylinder (22) to pull the die (62) down against and into conformity with the surface of the die cylinder, at the same time flattening the bubble seal (76). A key (68) at a trailing edge (66) of the die (62) locates in an axial keyway (50) in the die cylinder (22) to circumferentially position the die (62); a bolt (90) is then inserted at a leading edge (86) of the die (62) to establish axial location. During operation the die (62) is held in position by the vacuum. Beam sensors (56, 58) and light reflectors (52, 94) may be incorporated to sense when a wrong die (62) is present and shut down the apparatus. Ball valve members (150) may be incorporated in the surface of the die cylinder (22) to distribute the vacuum and also to enable the die (22) to be rolled along the surface of the die cylinder while initially being positioned.
摘要（中）：

用于在模筒（22）上安装模具（62），特别是刚性切割模具的方法和设备包括沿着模具上的密封件（76）具有气泡（116）以桥接模具（62） ）和模具圆筒（22），当模具最初定位在模具圆筒（22）上时。 该气泡密封件（76）使得能够在初始定位的模具（62）和模筒（22）之间施加真空以将模子（62）向下拉并抵靠在模筒表面上，与之相同 实时平坦化气泡密封（76）。 位于模具（62）的后缘（66）处的键（68）位于模缸（22）中的轴向键槽（50）中以沿周向定位模具（62）; 然后将螺栓（90）插入模具（62）的前缘（86）以建立轴向位置。 在操作过程中，模具（62）通过真空保持在适当的位置。 光束传感器（56,58）和光反射器（52,94）可被结合以感测何时存在错误的管芯（62）并关闭设备。 球阀构件（150）可以结合在模筒（22）的表面中以分配真空并且还使模具（22）能够在初始定位时沿着模筒的表面滚动。
