COLOR CAMERA INSPECTION SYSTEMS ADDRESS CHALLENGING CLASSIFICATION ISSUES IN PULP APPLICATIONS
7 December 2020
AMETEK Surface Vision, a leading provider of online surface inspection solutions, is helping address the challenges in detecting pulp contamination with its advanced automated color inspection technology.
Surface inspection systems are integral to the pulp-making process by providing a full inspection of the pulp, an essential raw material in the production of paper. The production process presents a unique set of challenges as pulp is not a homogeneous product due to the presence of different fibers and particles of varying colors.
Additionally, the dirt content of pulp is an important quality factor in determining its suitability for fine paper production. The Technical Association of the Pulp and Paper Industry defines dirt as “any foreign material in a pulp sheet which, when examined by reflected light, has a marked contrasting color and an equivalent black area of 0.04 mm2 or greater.”
AMETEK Surface Vision provides the pulp and paper industry with automated inspection systems, using multiple line scan cameras installed across the inspected material, supporting the pulp-making process by providing a complete and thorough inspection.
The SmartView system provides a highly-effective and accurate automated inspection system optimized for pulp inspection, utilizing a combined transmission-reflection view.
Volker Köelmel, Surface Vision’s Global Manager of Plastic, Nonwovens & Paper ,said: “Our technology in surface inspection systems successfully supports the pulp-manufacturing process by providing tools specifically designed for pulp inspection, including defect area statistics, dirt count, and parts per million. By delivering the best aspects of light and reflection through SmartView, the inspection image looks smoother, images of the defects from the inspected surface are precise, and defects located inside the pulp are sufficiently visible.”
