Steel plate lug detector
专利汇可以提供Steel plate lug detector专利检索，专利查询，专利分析的服务。并且PURPOSE: To achieve a higher productivity by making an irradiation light alone incident upon an industrial TV from sodium lamp having a very narrow spectrum to prevent stoppage of a line positively due to disability to detect lug ends of a steel plate.
CONSTITUTION: A glass window 2 using a heat proof glass is provided at a part of a celling section 1a of a furnace 1 located right above with lug ends of a steel plate 4 running in the furnace 1. An industrial ITV3 is arranged facing this glass window 2 and a projection light of sodium lamp 6 is allowed to irradiate a passive reflector 7 through a glass window 5 using a heat proof glass provided at a part of the side wall 1b of the furnace 1 located on the side of the passive reflector 7 provided in the furnace 1. In this case, a part of the passive reflector 7 appearing at a part of a detection line is distinctly bright (white) while a part of the steel plate 4 appears dark (black). And thus, a contrast between the passive reflector 7 and the steel plate 4 is detected clearly.
