43 Extrusion Asia Edition 1/2020 ISRA VISION AG Industriestr. 14, 64297 Darmstadt, Germany www.isravision.com/de/ 有了这种颜色报告，缺陷的检测和判定就容易多了 Detection and classification of defects is much easier with this kind of color reports ISRA检测软件使不可见的缺陷成为可见缺陷，以便及时优化生产 工艺 The ISRA Inspection software makes invisible defects visible to optimize the production process in time 于各种应用。与该公司的图像处理硬件和软件一样，伊斯拉 的摄像机和照明技术都是由自己公司设计和制造的。这样， 所有组件都可以精确地相互定制，并确保了最佳的视觉智 能。 当今全球市场对于印刷有着高质量的要求，塑料薄膜制 造商面临着越来越多的挑战。 竞争在加剧，下游行业客户的 期望也在增长。 现在，用于软包装的薄膜，电池产品中的隔膜层以及食 品、无菌、卫生和制药行业的无纺布产品都必须具有无懈可 击的质量。 正如通过智能数据分析和分类来检测缺陷一样， 根本原因分析对于作为生产过程中的一部分来识别和纠正生 产中的缺陷原因至关重要。 “零缺陷策略”是长期满足高标准要求的唯一方法。 这样 做的结果，生产商将能够提高产品质量并提高生产效率。 S ince conventional inspection systems for plastic films detect defects using black and white cameras, critical color defects such as oil spots cannot be classified correctly and maybe even missed altogether. To tackle this problem, ISRA VISION has now developed a solution that is unique on the market: The SMASH inspection systems have now been enhanced with a new em- bedded vision color camera and HDR technology that also de- tects the coloring of the material and any defects for the best possible classification. In addition to their compact design, the innovative all-in-one modules are highly cost- effective. This is achieved by using fewer and smaller components to enable leaner systems and lower investment costs while aiding integra- tion and simplifying maintenance. The future belongs to color cameras In order to be able to reliably detect and distinguish between black-and-white and color defects, it is necessary to have genuine color cameras as opposed to the color LED, given its li- mitations. ISRA has now introduced a unique embedded color camera in 8K resolution. The revolutionary, intelligent color ca- mera enables a black-and-white and a color image to be gene- rated simultaneously in a single scan. There are no concessions when it comes to resolution – even at high speeds. Compared the competition, which only offers B/W cameras with colored LED lighting, ISRA’s genuine embedded color ca- meras offer real advantages thanks to their additional HDR technology. Dirt, thin areas, and holes in the material can be re- liably detected and classified, delivering crucial advantages over competitors. Instead of just one image, multiple images are captured with varying light intensities seen from different angles. The solution is for manufacturers of a wide range of web products and is suited for a variety of applications. As with the company’s image processing hardware and software, ISRA’s camera and lighting technologies are designed and manufac- tured in-house. In this way, all components are precisely tailor- ed to each other and guarantee the optimum in visual intelli- gence. Quality printing for today’s globalized markets poses increasing challenges for manufacturers of plastic films. The competition is growing, as are the expectations of customers in downstream industries. Flawless product quality is now a must for films intended for use in flexible packaging, separator layers in battery produc- tion, and nonwoven products from the food and aseptic, hygie- ne and pharmaceutical industries. Just as detecting defects through intelligent data analysis and classification, root cause analysis is, therefore, essential in order to identify and remedy the causes of defects in production as part of a zero-defect strategy. This is the only way to meet the high standards requir- ed in the long term. By doing so, the producer raises both prod- uct quality and process efficiency.
