The portfolio of Hammer-IMS systems support inline measurements with single or multiple sensors. The use of our Marveloc and machine-vision technologies reduces the occurence of false-negatives in anomaly detection tasks, or intensifies thickness or basis-weight measurement of the material profile. Marveloc sensing technologies comprise of M-Ray (electro-magnetic), L-Ray (laser), C-Ray (capacitive) and U-Ray (ultrasound) sensor types. Hammers-IMS typically integrates multiple sensors into fixed or moving Marveloc-CURTAIN solutions. Such multi-sensor (or multi-head) approach is cost-effective since the sensor heads are pure electronic components and can be flexibly positioned on our CURTAIN scanning frames at multiple positions. Hammer-IMS can integrate two, three, four or eight sensor heads in a single CURTAIN solution. Check the video aside for a demo of a four-headed Marveloc-CURTAIN system.
Turn-key scanning CURTAIN systems execute fast profile measurement in the cross-machine direction, yielding a near 100% coverage of the material during production. Many industry applications could benefit from such a multi-sensor from Hammer-IMS among which applications where very localized anomalies or holes need to be detected in the food packaging film industry. In some cases the shorter time interval for multi-head systems between succeeding measurement points in the machine direction can help to find unwanted periodic behavior of thicknesses or basis-weights. For that, our software can be extended with various analysis tools. In high speed textile coating based on a calender process, multi-headed systems can provide quicker feedback to the operator compared to a classic one-headed system.
As previously mentioned, the Marveloc-CURTAIN systems of Hammer-IMS can accommodate multiple M-Ray sensors, but also third-party technologies that might help to learn even more about your production quality:
