PROBLEM TO BE SOLVED: To provide a conveyor having zero back line pressure by eliminating collisions of carried products by a zone accumulator. SOLUTION: This conveyor is provided with a belt 10 located at the outside and a belt 12 arranged at the inside of the belt 10. A plurality of rollers 16 are rotatably provided on the belt 10 located at the outside. Peripheral side surfaces of the rollers 16 are projected from both surfaces of outside surface and inside surface of the belt 10 arranged at the outside. The peripheral side surfaces of the rollers 16 projecting to the outside surface is in contact with a lower side of the carried product. The outside surface of the inside belt 12 is constituted to be in contact with the peripheral side surfaces of the rollers 16 projecting from the inside surface of the outside belt 10. By relative movements of both of the inside and outside belts 10 and 12, the rollers 16 in contact with the inside belt 12 are rotated. Driving advancing directions of the belts 10 and 12 are the same direction or relatively different directions. By the relatively advancing speeds of the two inside and outside belts 10 and 12, rotating direction and rotational speed of the rollers 16 are determined. COPYRIGHT: (C)2006,JPO&NCIPI
