A pressing pulley is formed of a tapered roller having an angle same as a taper angle of a head pulley and having a length in a rotation axis direction of a tapered outer tube which is set to be shorter than a length in a rotation axis direction of a taper-shaped outer tube of the head pulley, and the pressing pulley is arranged in a state where a large-diameter-side end portion of the tapered outer tube is positioned in a vicinity of an outer peripheral edge portion of a fan-shaped belt and the pressing pulley is inclined so that a peripheral surface of the tapered outer tube presses a portion close to the outer periphery in a length from a pivot to the outer peripheral edge portion of the fan-shaped belt wound around the head pulley against a peripheral surface of the taper-shaped outer tube of the head pulley.

A conveyor system, is provided having a continuous looped conveyor belt having first and second conveyor belt portions, first and second opposite ends, and having first and second direction reversing members disposed at the first and second opposite ends. Each of the first and second conveyor belt portions also has an upper surface, and a lower surface. A series of regularly spaced followers are provided on the belt, and these followers are moved by a conveyor belt drive mechanism comprising at least one rotational drive member which is positioned in, and which rotates in, a plane which is parallel to the upper or lower surfaces of the first or second conveyor belt portions. The rotational drive member includes a series of teeth on the drive member. When rotated, the teeth releaseably engage with the followers on the belt to provide a low profile conveyor drive system.

A conveyor system is for intended use in conjunction with the conveyance of articles, such as for being sorted for downstream processing. The system comprises a conveyor, which may be an endless conveyor including a forward run and a return run. The conveyor may have a tilted conveying surface for supporting the articles being conveyed. A low friction guide extends along the conveyor for engaging the articles being conveyed by the conveyor, which may include rollers for providing rolling contact for the articles during conveyance. Related methods are also disclosed.

A curved belt conveyor includes a supporting structure having a base for supporting the conveyor on a floor and a curved top portion engaged to the base. The curved top portion defines at least one curved advancing plane for one or more objects and/or articles to be moved along a curvilinear advancing path and has an arched wide side and an arched narrow side opposite each other. An endless conveyor belt is operatively engaged to the curved top portion to define the curved advancing plane and the conveyor belt is at least partially around at least two revolving rollers rotatively engaged to the curved top portion. At least one of the rollers is movable relative to the other between a distant position, wherein the conveyor belt is under tension and not removable from the rollers and a close position, wherein the conveyor belt is loose and removable from the rollers.

A spiral conveyor includes a mesh chain spirally wound around and rotate synchronously with an outer circumference of each rotary drums. The inner side of each chain link of the mesh chain close to the rotary drum is provided with a drive head extending towards a drum body of the rotary drum. The drive head is provided with a convex-arc edge and includes an arc slot provided on each of two sides or on a single side of the drive head. Driving poles are evenly distributed around the outer circumference of the rotary drum and engage with the drive heads of each layer. When the inner side of the mesh chain adapts to the perimeter of the outer side of the mesh chain, the drive head on the inner side of the mesh chain engages with the driving pole.
