MATRIX VISION DELIVERS CAMERA TECHNOLOGY FOR HIGH SPEED LE MANS FOLDING SYSTEM FROM MBO
Mar 7, 2017

To protect the operator, many finishing machines are fitted with a housing. For the latest "Le Mans" generation of folding machines, MBO was looking for an industrial camera to allow the operator to see directly into the machine when the panelling is closed. In MATRIX VISION, MBO found not only the right camera supplier but also a consultant providing the appropriate hints, tips and suggestions at the right time to permit successful, fast and thus cost-effective integration of the camera.
Le Mans gets pulses racing for a great number of car enthusiasts. High speeds, rapid changeover, different classes, 24 hours long, these are the ingredients for a successful and globally recognised brand. So the choice of name for the newly developed high-speed folding system Le Mans from MBO could not be more appropriate. In line with this, the folding system specifications also focus on the speed and ergonomics. With a folding volume of approx. 70 million printed sheets and more per year or up to 23,000 sheets per hour as the maximum (16-sheet folded to A4), the system reaches speeds at which it is necessary to incorporate protective cladding to avoid danger to the operator. This makes it difficult for the operator to adjust and check the folded products, however. But a solution quickly came into view: A camera system to provide the operator with a direct view into the machine.
Advantages of the camera system and requirements
The advantages of an image-based camera system were quickly identified by MBO. In addition to traceability in the event of faults, the safe monitoring of ongoing production was also important. The requirements for the system were also quickly established. Software was required to display the live images from multiple cameras simultaneously as thumbnails at a reduced image refresh rate. When the operator selects a thumbnail, an enlarged version of the image was to be displayed at the correct refresh rate. In addition, the operator should be allowed to view the last few seconds of production in slow motion. The camera hardware should be able to capture at least 100 frames per second, have a resolution of at least 640 x 480 pixels, and provide greyscale images.
Camera expertise and more from an external source
With more than 50 years of experience, MBO would easily be capable of developing the software and the folding machine in-house, but the firm wanted to play it safe with the camera system, and as a result brought the image processing experts from MATRIX VISION in on the development process at an early stage. Alongside MBO, the experts from MATRIX VISION highlighted the various aspects of image recording, such as cameras and sensors, lighting, optics, hardware as well as connection and cabling.
Three cameras are required to monitor the parallelfold, crossfold and threefold. The MATRIX VISION product range includes a number of Dual-GigE cameras from the mvBlueCOUGAR-XD series. Ultimately, MBO decided to use the mvBlueCOUGAR-XD104d as a greyscale option thanks to the appropriate resolution and refresh rate, and the impressive image quality. The Pregius CMOS sensor IMX174 from Sony integrated into the camera also impresses with its reduced dark noise and dynamic range of over 71 dB. As different exposure scenarios arise in the folding machine, a high dynamic scope is essential.
For correct storage of the image data via Dual-GigE, MATRIX VISION recommended the use of three separate Dual-GigE network cards and three SSD hard drives. With the GigE cables as well as three cables to control the cameras, there was potential for the wiring to become rather complicated. Here too, MATRIX VISION offered a simplified solution with custom cable production which made the three control cables superfluous. Naturally the cables can be screw-fastened, contributing to the robustness of the camera system.
MATRIX VISION also provided the appropriate support in terms of optics and lighting. The distance between the camera and the object was about 140 mm, whereas the image size was to be 75 x 60 mm. These stipulations were met using a suitable 6-millimetre lens. In the case of the lighting, a white LED light ring, for screw-attachment onto the lens, provided the relevant solution. MBO was extremely satisfied with the overall results, the choice of individual components and the time saved thanks to consultation with external experts.
Conclusion
Whether due to lack of time or cost pressures, it is not unusual for attempts to get involved in a new subject area to fail. Industrial image processing and image recording in particular are fields where the devil is often in the detail. So much the better if you can find a partner to help you navigate through the sticking points right from the off. In this case, MBO GmbH & Co. KG was able to concentrate on its core competencies thanks to the external support received. The feedback has confirmed that this was the right approach. At Drupa 2016, the world's largest trade fair for print media in Düsseldorf, visitors were delighted by the new folding machine. The continuous production monitoring from the three cameras, with the images also being saved continuously allowing the operator to look "into the past", was also positively received.
