包装机械中自动定性识别多种颜色的原理及方法

Principles and Methods Study on Several Colors Distinguishing Automatically and Qualitatively in Machinery System

讨论包装机械中自动识别颜色的原理和一种能实现“颜色电信号”转变的方法，它可应用于包装机或印刷机上，取代目前广泛使用的单色识别技术，成为多种颜色的定性识别装置，用于产品包装图案、印刷色标的识别以及同一些测试控制仪器配套或实验室作教学演示。

The paper deals with the principle of several colors distinguishing automatically and qualitatively in machinery system,and presents an electric circuit which can turn the “color”to “electric signal”,and can be fixed on the packaging and pressing machine to replace the device used only one color distingushing device,it can be used to discern the colors of package pattern,distinguish printing color signal,fit in with some testing and controlling equipment,or act as an illustration means for school.
