摘要： An automatic tool changing and verification system and method and system for switching engraving heads is shown. The tool changing method and system comprises a turret having a plurality of work holders for holding a plurality of replacement tools. Some of the work holders are empty for receiving a worn tool from an engraving head on the engraver. When it is desired to change a tool on the engraving head, an empty tool holder is indexed to a tool changing position opposite the engraving head whereupon the worn tool is transferred from the engraving head to the tool changer. Thereafter, the tool changer is indexed to position where a replacement tool is situated in opposed relationship with the engraving head. In the embodiment shown, the tool changer comprises a pneumatic system for causing the worn tools and replacement tools to be transferred between the engraving head and the tool changer. Other features of the invention comprise a tool verification routine for verifying that a tool on an engraving head is the correct tool and/or is not defective. Moreover, another aspect of the invention includes a engraving head turret having multiple engraving heads for indexing into engraving relationship with a cylinder to be engraved. The multiple-engraving head turret facilitates, for example, reducing the number of required tool changes.

摘要翻译：示出了用于切换雕刻头的自动换刀和校验系统及方法和系统。刀具更换方法和系统包括具有多个用于保持多个替换工具的工件保持器的转台。一些工作持有人是空的，从雕刻机上的雕刻头上接受磨损的工具。当需要改变雕刻头上的工具时，空的工具架被转位到与雕刻头相对的工具更换位置，随后磨损的工具从雕刻头转移到工具更换器。此后，更换器被转位到替换工具位于与雕刻头相对置的位置。在所示的实施例中，工具更换器包括用于使磨损的工具和更换工具在雕刻头和工具更换器之间传送的气动系统。本发明的其它特征包括用于验证雕刻头上的工具是正确的工具和/或没有缺陷的工具验证程序。此外，本发明的另一方面包括具有多个雕刻头的雕刻头转塔，用于与要雕刻的圆柱分度成雕刻关系。例如，多雕刻头转塔有助于减少所需的刀具更换次数。
