Eltromat unveils digital stroboscope for label inspection

At Labelexpo Americas 2012, Eltromat unveiled the new camera system TubeScan, described as 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,’ said Dr Krebs, managing director of Nyquist Technology. ‘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 color 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.

TubeScan is the first developed product of the company Nyquist Technology, a joint venture between Eltromat and Nyquist Systems.

Specific requirements in the design were 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,’ said Dr Kipp, CEO of Eltromat, said: ‘We are convinced that our systems will help the user in the market to meet quality standards and improve processes.’
