Cette trieuse utilise une caméra pour surveiller constamment les produits alimentaires circulant sur un tapis roulant à 1,5 m/s.Tout corps étranger comme du plastique ou des débris végétaux sont détectés et éjectés à l’aide d’une lame d’air.

“Right now we are running the demonstration using dried cabbage on the conveyor belt. We developed this to target customers such as dehydrated vegetable producers, or shops that handle small fish, or seaweed.”

“Up until now one camera has been able to distinguish a small area only 150mm wide, but now one camera can inspect an area four times as wide, or 600mm, so this equipment can process four times as much. The cost has been around 20 million yen for a four camera system, but we have been able to lower that to 12.8 million yen.”

La lame d’air qui élimine les corps étrangers avec une extrême précision possède 120 buses, chacune de 5 mm de large. Dans le cas du chou déshydraté utilisé dans la démonstration, il peut traiter 300 à 400 kg par heure.

“There can be a lot of debris like bits of plastic blown around by the wind, and this debris can get on the cabbage. It also helps to remove bits of brown dried material.”

“We are dedicated to using an area sensor method to capture images for sorting. The line sensor method that has been used until now has limits on the sorting precision, but the area sensor method can capture the shape of the product, making even better sorting possible.”
