PolyScan: Online control of foam production

X-ray scanner system for online measurement of the vertical density and surface profile of foam mats 
PolyScan is designed for on-line inspection of flexible foam, manufactured as a mat using double wall conveyer belt system. The instrument measures the foam density and detects the vertical dimension of the foam mat. The measurement system is housed in a vertical frame, which is installed on the production line at a suitable position, located after termination of the conveyor sidewalls. The vertical frame holds an X-ray scanner for horizontal line-measurement in a direction perpendicular to the length axis of the conveyor. The X-ray scanner has an X-ray source and an X-ray sensor. The X-ray scanner can, using an automated motor drive, move vertically up and down in the frame and do quick horizontal measurements at short intervals ranging from bottom of the foam mat to slightly above top of the foam mat.

Advantages

• On-line measurement system with short response times
• Data from the system can be used for production adjustment/control
• Measures uniformity homogeneity of the foam
• Can help insure that the produced mats are of the correct height
• Can help save raw materials in the production
