In addition to preform inspection systems, the company develops high-speed inspection systems for various product categories. In the case of cap inspection, the company has established inspection systems capable of handling plastic- and aluminium caps at speeds of up to 2,500 bpm, featuring a comprehensive inspection of the entire product without any corners cut. Over the past 28 years, the Korea-based company has built a diverse lineup in packaging inspection systems and increased its market share. Recently, the company has responded to growing consumer demands with its AI technology. While conventional cap inspection systems focused on detecting defects such as specks and foreign objects on the inner and outer surfaces of the caps, newer requirements demand that defects in the design and printing of the caps are also detected. This requires advanced software technology and precise optical conditions. For the high-performance cap inspection systems, separate lineups have been developed for plastic and aluminium product inspections, applying specialised-optical conditions. The inspection of the inner part of plastic caps can detect foreign particles as small as 0.2mm between the screw threads. In the case of cap inspection systems, high-speed processing is critical. Any malfunction in the inspection system can lead to issues with a significant volume of products. The company has implemented a fail-safe technology to eliminate the possibility of uninspected items being mixed with normal products. Additionally, a dual signal processing system has been applied to all signals. This dual signal system alleviates instability of the system caused by noise signals, accurately processes received signals, and categorises unclear signals as defects, enhancing the credibility of inspected normal products. P&S Technology’s AI technology employs machine and deep learning. It claims high accuracy in determining cap defects in real-time by analysing a vast database of stored images and patterns. The company states that it minimises human errors and setup time during the production process. P&S Technology’s cap inspection systems account for 20% of sales in regions like Korea, Japan, and China (Universal Can, Bright Metal, Taiwan Hon Chuan) in Asia. www.pnstech.co.kr 28 – 30 November 2023 Nuremberg, Germany www.braub viale.de/en Find out what drives the beverage industry worldwide.
