An article selecting system for sorting and discriminating a plurality of types of articles comprising a branch path provided intermediately of a transport path which transports n-types (n.gtoreq.3) of different articles for sorting articles of the n-types into 2 types of articles and n-2 types of articles, a gauge located at a particular position on a transport path for the 2 types of articles for displacing the articles to two positions in accordance with the 2 types, and an article arrival detecting sensor and an article presence detecting sensor for indicating whether a specific article type in present. In one embodiment, two specific article types are allowed to progress along a selected path due to an overlappig coding feature of such two specific article types, while all other article types are diverted to a different path. In another embodiment in which there are three article types, one specific article type is allowed to progress along a selected path due to its particular coding, while the other two article types are diverted to a different path.
An article selecting system comprising a branch path and a gauge plate provided intermediately of a transport path which transports n-types (n.gtoreq.3) of different articles for sorting articles of the n-types into two types of articles and n-2 types of articles, a second gauge plate located at a particular position on a transport path for the sorted two types of articles for displacing the articles to two positions in accordance with the two types, an article arrival detecting sensor and an article presence detecting sensor indicating whether a specific article type is present on said transport path for the sorted two types of articles.
An article selecting system wherein n-types (n.gtoreq.3) of different articles are carried by different respective trays and the trays are transported on conveyor belt being guided by guides disposed along the conveyor belt, comprising a common transport path for transporting n-types of articles, a first path continuing from the common transport path via a branched point for transporting two types of articles, a second path branched from the common transport path at the branched point for transporting n-2 types of articles, a first discriminating device located at the branched point, and a second discriminating device located at a certain position on the first path for discriminating the two types of articles, a tray having an annular groove peculiar to an article carried thereon and formed on an outer circumferential periphery of a disk-formed base member thereof and said first discriminating device including a reference plate located at a position spaced substantially a distance equal to the height of the base member of the tray from an upper face of the conveyor and a gauge plate secured in integral relationship with the reference plate which may be admitted into the groove.
