eltromat GmbH introduces world's first digital stroboscope for label inspection

Quality control has to be simple during the finishing process of label webs but most importantly very reliable. On this year’s Labelexpo Americas eltromat introduces the new camera system TubeScan, a powerful alternative to the current methods of quality control.

Conventional methods such as counting of labels with photoelectric sensors or the running web visualization with strobe lights are often reaching limitations and are complicated to use. On the other hand, automatic image inspection systems are oversized and too expensive for many applications. The concept of TubeScan sets a new standard with the intelligent combination of imaging technology and the stroboscopic principle.

TubeScan provides two important functions with which much more process safety is achieved. The function „digital strobe web viewing“ always delivers a steady image and true colour fidelity – regardless of the line speed. Thus, the operator retains in control of the entire production, even during the critical start and stop phases of the machine. With the function „missing label detection“  the system is not only counting accurately labels and missing labels per lane and in total, but detects also remains of label matrix across the entire web width. This can save the use of more expensive sensor technology with their time-consuming adjustments.

TubeScan is the first developed product of the company Nyquist Technology GmbH & Co. KG, a joint venture between eltromat and Nyquist Systems. "With the new system, we will close the gap regarding quality control of flexible packaging and adhesive labels," says Dr. Krebs, Managing Director of Nyquist Technology. Specific requirements in the design were in addition to ease of use also a high image refresh rate, automatic synchronization, as well as the high-quality image display also of reflective or metalized surfaces. Hereafter a simple image processing functionality for counting labels and the false label control is also important. “TubeScan provides all that reliably,” confirms Dr. Kipp, CEO of eltromat GmbH and further says “We are convinced that our systems will help the user in the market to meet quality standards
and improve processes.”
