Abstract

EL APARATO DE LA PRESENTE INVENCION PERMITE QUE SE LEAN CODIGOS OPTICOS EN OBJETOS TRANSPORTADOS SOBRE UN PLANO DE SOPORTE QUE TIENE MEDIOS PARA DESPLAZAR LOS OBJETOS A LO LARGO DE UNA DIRECCION DE AVANCE. EL APARATO COMPRENDE: - UN EXPLORADOR DE RAYOS LASER QUE EMITE LUZ MODULADA; - UNA UNIDAD DE PROCESO DE DATOS CONECTADA AL ESCANER; - UN PRIMER MEDIO DE EXPLORACION PARA GENERAR AL MENOS UNA PRIMERA EXPLORACION EN UN PRIMER PLANO DE EXPLORACION, A FIN DE MEDIR LA DISTANCIA INSTANTANEA DE AL MENOS UN PUNTO EN LA SUPERFICIE DE CADA UNO DE DICHOS OBJETOS DESDE EL ESCANER; - UN SEGUNDO MEDIO DE EXPLORACION PARA GENERAR UNA SERIE DE SEGUNDAS EXPLORACIONES EN UN SEGUNDO PLANO DE EXPLORACION, DIFERENTE DEL PRIMERO, A FIN DE LEER EL CODIGO OPTICO EN EL OBJETO; - UN MEDIO PARA REGULAR EL AJUSTE FOCAL DEL RAYO LASER DE ACUERDO CON LA DISTANCIA MEDIDA CON LA PRIMERA EXPLORACION.
