要快速无差错地对包装品进行计数,机械键控至今都未达到令人满意的效果。一旦产品厚度参差不齐,各个产品的间距很小,如流水线上的片状产品,要准确计数就更为困难。为了提高计数质量,就必须校正键控器,因为快速运转必然造成机械磨损。光学激光计数器一台激光器、两支光电管和一台微处理机使计数技术得到发展。潮湿的印刷油墨及印刷面与非印刷面间 To count packages quickly and error-free, mechanical keying has hitherto not achieved satisfactory results. Once the product thickness varies, the distance between the various products is small, such as the product line on the pipeline, to accurately count even more difficult. In order to improve the counting quality, it is necessary to calibrate the keyer, because the rapid operation will inevitably cause mechanical wear. Optical Laser Counter A laser, two photocells and a microprocessor enable counting techniques to evolve. Wet printing ink and printing surface and non-printing surface
