Claims (1)

[Scope of Claim for Utility Model Registration] (1) A base, a head pulley and a tail pulley that are pivotally supported by the base, a conveying part that is stretched between the head pulley and the tail pulley, and corresponds to the central part in the transverse direction; an endless belt consisting of a neck connected to both sides of the conveying section and ears connected to both sides of the neck, the thickness of the ears being approximately equal to the thickness of the conveying section; An outward path that comes into contact with the back surface of the conveying surface of the endless belt heading toward the head pulley, and guides the endless belt by deforming it so that the cross section has a palm-shaped shape in which both ends overlap at the top, and a cylindrical shape in the center. a guide member; a first belt reversing device provided on the return path side of the endless belt for reversing the endless belt wound around the head pulley so that the conveyance surface of the endless belt faces upward; a return path guide member that deforms and guides the endless belt so that at least the center portion thereof has a cylindrical shape in cross section, with the conveyance surface of the endless belt held inside and passed through the first belt reversing device; The endless belt provided on the return path side of the endless belt and directed from the return path guide member toward the tail pulley is reversed in a direction opposite to the reversal direction of the first belt reversing device so that the conveying surface of the endless belt is directed downward. A cylindrical belt conveyor comprising a second belt reversing device. (2) The return path guide member contacts and engages with the back surface of the conveying surface of the endless belt, and deforms the endless belt so that the cross section thereof has a palm-shaped shape in which both ends overlap at the top, and a cylindrical shape in the center. The cylindrical belt conveyor according to claim 1, which is a utility model for guiding the conveyor. (3) The return path guide member contacts and engages with the back surface of the conveying surface of the endless belt, and guides the endless belt by deforming it so that both ends overlap in a spiral shape upwardly and the central portion has a cylindrical shape in cross section. A cylindrical belt conveyor according to claim 1, which is a utility model. (4) At least one of the first belt reversing device and the second belt reversing device each includes a rod-shaped body disposed along the moving direction of the endless belt, and a predetermined interval between the rod-shaped bodies. Utility model registration claimed in claim 1, which comprises a plurality of rollers disposed in such a manner that their axes are substantially perpendicular to the longitudinal direction of the rod-shaped body and whose angles with respect to the longitudinal direction of the rod-shaped body are sequentially changed. cylindrical belt conveyor.
