Erhardt+Leimer will present its latest products for the plastics industry at the K Show, which takes place from October 19-26 in Düsseldorf, Germany. The Erhardt+Leimer booth C20 in Hall 4 will centre on the print image monitoring system ELSCAN OMS 6 and the new actuating drive AG 9.
The new print image monitoring system ELSCAN OMS6 (left) contains two 12-megapixel cameras, which ensures exceptional image quality in Ultra-HD (4x HD) with perfect colour reproduction, without apparent distortion in the edges of the image. Thanks to the maintenance and wear-free fixed focus lenses, it can be zoomed without delay. The short flash times of the LED flash permit web speeds of up to 1,200m/min. Optionally, special UV and paint flashes can be used to illuminate particularly critical print images perfectly.
Another feature is high-speed traversing: The camera can move at positioning speeds of up to 900mm/s. The drive unit is collector-free, making the camera crossbeam virtually wear free. Web widths of up to 2,800mm can be implemented.
The new actuating drive AG 9 is used in combination with the colour line sensor FE 52 and the command station DO 30 for web guiding on unwinders, rewinders and in large pivoting frames. Ethernet networking with response times of 1ms and an actuating speed of up to 60mm/s ensure maximum actuating dynamics. Even at a high winding speed, that allows optimal compensation of tumbling errors, for example. Control frequencies up to 4Hz are possible. The motor used in the actuating drive is brushless and thus wear-free. The position is acquired via an integrated absolute encoder. That means that no reference run is required on commissioning, and the current position of the actuating drive is not lost even if the power fails.
E+L’s proven inspection solutions shouldn’t be left out. The ELTIM measuring system will be presented at K, in addition to the ELSIS, E+L’s classic for surface inspection. ELTIM allows for the contactless measurement of layer thickness, basis weight and other material properties. The highlight of this: the measurement is done using ultrasound, without the need for complex system calibration. The measuring accuracy is up to 0.2 per cent.
The heart of the ELSIS surface inspection is the robust OL 60 line scan camera, whose image processing functions have been continuously further developed. Especially the detection and classification of complex and low-contrast defects has been improved considerably. The modular structure (every camera is an independent image processing system that communicates with the ELSIS server and the other cameras in the system via Ethernet) makes the inspection lines very compact. The time required for mechanical integration, installation and commissioning is reduced to a minimum thanks to the smart cameras.
