Abstract: A conveyor device for food includes bar members coupled with coupling members to form a conveyor belt. A guide rail supports the belt, and a sprocket meshes with tooth-shaped portions formed on the coupling members. Each coupling members includes a metallic insert member. A wear resistant resin member incorporating the metallic insert member has a bent shape with an interior space(s), both end portions coupled to a first bar member, and a pair of slotted holes in which a second bar member which is adjacent to the first bar member is loosely fitted. Wear resistant resin members form tooth-shaped portions and slide surfaces which slide on the guide rail. Meshing portion of the sprocket which meshes with the tooth-shaped portions is formed of wear resistant resin. Contact pressure and friction in a slide portion between the belt and the slide portion is prevented from increasing in low temperature environments.

Abstract: To prevent the production of metal powder in a conveyor device for conveying food (12), and prevent the contact pressure and wearing from increasing at the slide portion between a conveyor belt (15a, 15b, 15c and 15d) and a guide rail (82) in a low temperature environment. A conveyor device for conveying food includes a large number of round bars (60) which forms the conveyor belt (15a, 15b, 15c and 15d), coupling members (62) which are fixed to both ends of each of the round bars (60), a guide rail (82) which slidably supports the conveyor belt (15a, 15b, 15c and 15d), and a slide block (78) fixed to each round bar (60) and configured to slide on the guide rail (82). The coupling members (62) includes rotatable rollers (74), the rollers (74) mesh with a sprocket (48, 50), and the sprocket (48, 50) conveys the conveyor belt (15a, 15b, 15c and 15d) in a conveyance direction. The rollers (74) and the meshing portion of the sprocket (48, 50) include a wear resistant resin member.
