タイヤの表面検査方法および装置
Document Type and Number:
Japanese Patent JP5019849
Kind Code:
B2
Abstract:
Disclosed is a tire surface inspecting technique capable of surely discriminating rubber pieces of a quality different from that of a tire embedded in the surface of the tire by vulcanization from the tire. A first illuminating unit 11 include paired first light projectors 11a and 11b that project light respectively from opposite sides toward an objective line L on a tire T. A second illuminating unit 12 include paired second light projectors 12a and 12b that project light respectively from opposite sides toward the objective line L in a direction different from that in which the first illuminating unit 11 project light. The first illuminating unit 11 and the second illuminating unit 12 operate alternately for illumination. The line camera 3 forms an image of a part of the surface of the tire corresponding to the objective line L in synchronism with the respective illuminating operations of the first and second illuminating unit. Illumination and image formation are repeated for different parts of the surface of the tire that are moved successively to a position corresponding to the objective line L. Images formed by the line camera are analyzed for the inspection of the surface of the tire T.
