High Precision Area Weight Measurement and Foreign Body Detection EcoScan NEO
Two advantages respectively two measuring functions based on x-ray technology are combined in one EcoScan NEO system. This is a “High Precision Area Weight Measurement” of the fiber mat and a “Foreign Body Detection”. Each measuring function can be created as a separate measuring system (stand-alone).
EcoScan NEO – FLY (High Precision Area Weight Measurement)
The EcoScan NEO - FLY measures the material distribution of wood fiber mats. For achieving high precision results during the commissioning of the system the empty forming belt is scanned and hereby weight distributions of the forming belt are recognized. The measured values are used to compensate influences of weight variations of the forming belt itself during the later panel production. Thanks for the forming belt compensation and thanks for the use of the MultiEnergy technology the EcoScan NEO – FLY shows the material distribution in a high resolution lengthwise and crosswise to production direction. The system also automatically adjusts the sensitivity and the measuring speed according to the produced area weight (Example: MDF mat of 2.5 m width and 60 mm thickness scanned in just 3 seconds).
Measuring resolution: +/- 0.5% of the measured material
EcoScan NEO – FBD (Foreign Body Detection)
The EcoScan NEO - FBD is able to detect smallest foreign bodies in a fiber mat to prevent damages to the press belts. Foreign bodies are metallic or non-metallic pieces of material with high density (e.g. stones, plastic, resin lumps, wax balls, aluminum and steel). If a foreign body is detected a signal is given which can be used to automatically remove the part of the mat which contains the foreign body.
Example: (line speed 1m/s)
Polymer or resin (boards < 7mm): 3 * 3 * 3 mm
Polymer or resin (boards > 7mm): 5 * 5 * 5 mm
Metals (ferrous and non-ferrours): 2* 2 * 2 mm
The smallest detectable foreign bodies depend on the wood material (MDF, Particle Board, OSB), the material thickness, the material density and the speed of production.
