Title:
ARTICLE SIDE FACE INSPECTING DEVICE
Document Type and Number:
Japanese Patent JP3388714
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To quickly inspect the peripheral side face of an inspected article of complicated shape mainly of cylindrical shape on a conveyor by providing a reflecting mechanism for reflecting reflected light from the side face of the inspected article upward or downward, and the like.
SOLUTION: This inspecting device 1 is composed of a reflecting mechanism 10, a lighting mechanism 20, an image pickup mechanism 30, a processing mechanism 40 and a conveyor 3. The reflecting mechanism 10 reflects reflected light from the side face of an inspected article 2 upward, and the lighting mechanism 20 irradiates the side face of the inspected article 2. The image pickup mechanism 30 picks up the image of light from the reflecting mechanism 10, and the processing mechanism 40 processes an image signal from the image pickup mechanism 30. The reflecting mechanism 10 is constituted including a reflecting body of hollow conical shape provided to surround the inspected article 2 on its inside. The side face of the inspected article 2 can therefore be picked up as one image while moving the inspected article 2 continuously. Consequently, an inspection process can be incorporated in the middle of a conveying process to permit high speed processing.
