<p>PURPOSE: To prevent the kicking up of objects to be detected on an inclined chute and to improve detection accuracy by forming a storage section for supplying the objects to be detected again to a downstream side after once storing these objects in a section the inclined chute which receives the transported objects to be detected. CONSTITUTION: A parts feeder 2 is provided with the first inclined chute 3 having an angle of 49 deg. with a horizontal on its downstream side. A recess 10 having an arc shape in the section in a perpendicular direction as the storage section for supplying the cullets 1,..., etc., transported by the parts feeder 2 again to downstream side after once storing the cullets 1 on the part where the cullets are received in the first inclined chute 3. As a result, the cullets 1, etc., transported by the parts feeder 2 are once stored in the recess 10, by which the impact at the time of falling is offset and the kick up of the cullets on the inclined chute does not arise. Then, the detecting section of foreign matter and the discriminating section corresponding thereto are aligned and sure discrimination of the foreign matter alone is executed by a pinpoint.</p> |
