DETECTING DEFECTS RELIABLY IN THE FOOD INDUSTRY WITH MACHINE VISION
I 36
NNDEO, headquartered in Zaragoza, Spain, offers high-quality machine vision solutions for the automation of quality inspections with its INSPECTRA brand. Founded in 2016, the company has so far mainly been active in the food industry with its solutions and would like to gain a foothold in logistics in the future. For this purpose, the company has developed the Thermoseal & Label Inspector solution, which can be used to reliably inspect packaging and read labels. The device combines a wide range of equipment sophisticated technologies such as high speed and processing capture with INSPECTRA HSP technology, hyperspectral vision, deep learning, and high- performance RGB.
AUTOMATING PACKAGING INSPECTION FROM END TO END INSPECTRA’s goal was to develop an end-to- end automated solution for the packaging industry. The advantages offered by such a solution based on machine vision are: Higher detection rates of packaging defects, cost savings, as well as the comprehensive digitalization of production processes in order to be able to monitor and improve them. In practice, many companies’ employees still carry out the inspection process manually. In this process, defects are often not seen by the human eye. As a result, defective products enter the supply chain and end up with the end customer. The goal of an automated solution must therefore be to reliably detect all conceivable defects in packaging. These include, for example, anomalies in the sealed or heat-sealed area, in the tray, in the inner product, in the film, or in the labeling. Furthermore, 100 per cent automation of quality control reduces costs on the one hand and introduces objective criteria for sorting the

Maximum speed and detection rates of preferably 100 percent – these are the requirements for quality control in the packaging industry. The company INNDEO shows how these high requirements can be achieved with a sophisticated automation solution based on machine vision and deep learning technologies.
products to be inspected on the other. In addition, quality and production data can be continuously digitised and the corresponding indicators displayed in real time. Although the market offers several other machine vision devices and solutions, these often prove to be not robust enough, low performance, and difficult to adapt to
changes in production lines. Due to a lack of precision and reliability in defect detection, many users refrain from using such solutions and prefer to perform defect inspection manually. INSPECTRA wants to eliminate exactly these deficiencies with its machine vision solutions: “In order to ensure faster inspection processes and more robust
