Abstract:
1. A conveyor chain comprising: a plurality of link rows each having a predetermined chain width and being composed of a plurality of synthetic resin link modules disposed in a chain width direction, each link row having a loading portion for loading articles to be conveyed and hinge portions projecting from front and rear parts of said loading portion; wherein the plurality of link rows are linked together in a predetermined array pattern by linking the plurality of link rows in a chain longitudinal direction by inserting link pins through pin inserting holes formed through said hinge portions of the synthetic resin link modules of said link rows, wherein the plurality of synthetic resin link modules include a pair of non-magnet storing resin link modules and at least a pair of magnet storing resin link modules which have magnet storing blind holes which open in the chain width direction from link side surfaces of said magnet storing resin link modules, wherein the non-magnet storing resin link modules do not have magnet storing blind holes and wherein the link side surfaces of the magnet storing resin link modules each abut a side surface of a non-magnet storing resin link module; and wherein magnet pieces are insertably stored in said magnet storing blind holes of and are operable to magnetically attract and retain said articles, the magnet pieces being enclosed in the magnet storing blind holes by the side surfaces of the non-magnet storing resin link module adjacently disposed in the chain width direction to a magnet storing resin link module, the non-magnet storing resin link covering the magnet storing blind holes with the magnet pieces housed therein so as to secure the magnet pieces in the magnet storing blind holes.
