<p>PURPOSE:To simplify structure, save space and improve detection probability by measuring color of a delivery article by a diffuse reflection type photoelectric sensor, collating it to a color information of the delivery article separately input and reporting when they do not match to each other in the device in the title provided at the entrance gate or others of an automatic warehouse. CONSTITUTION:Measurement of color of a bobin B2 is carried out by a diffuse reflection type photoelectric sensor 17 as well as the bobin B2 is detected by way of temprorarily stopping the bobin B2 brought on a conveyor line 2 by a stopper 14 and blocking an optical path between a tropical reflection type photoelectric sensor 15 and a reflector 16 of a bobin detection means. Its result is sent to a comparison part 22 of a controller 30 and is compared with a color information of the bobin 2 sent through another transmission system 4. When the color conforms, the stopper 14 is released and the bobin 2 is transferred and placed on a carriage but when it does not conform, so it is informed.</p> |
