PURPOSE:To prevent abrasion of the nonmagnetic belt-like plate of a conveyor plate and coming-off of magnets of a chain, by laying rollers on the chain having a trackway along the lower surface of the plate so that a space is ensured between the nonmagnetic belt-like plate and the magnets. CONSTITUTION:A chain 2 is laid along the lower surface of a conveyor plate 1 and wound around sprocket wheels 3 at both ends of the chain 2. Two left and right magnets 4 are secured to each of yokes 6 which are attached to the lower ends of support fittings 5 at predetermined intervals along the chain 2. Further, on both sides of each yoke 6, rollers 7 are journalled to the upper part of each support fitting 5 to ensure a gap which prevents the conveyer plate 1 and the magnets 4 from being made in contact together. With this arrangement, it is possible to prevent the magnets 4 from coming off from the yokes 6 due to the contact between the magnets 4 and the nonmagnetic belt-like plate 8 of the conveyor plate 1, and also to prevent abrasion of the belt-like plate 8. |
