Patent number: 7051869Abstract: The beads of a beaded conveyor belt for a curve conveyor are constituted by a number of bead constituting bodies (2b) that are disposed over the entire periphery of the outer surface along the outer peripheral edge of a belt main body (2a) and that are narrow in the direction of the length of the belt. Further, the beads of a beaded conveyor belt for a liner conveyor are constituted by a number of bead constituting bodies (7b) that are disposed over the entire periphery of the outer surface along opposite side edge of a belt main body (7a) and that are narrow in the direction of the length of the belt. The conveyor belt is installed taut between straight type end rollers (15), and the width of the bead constituting bodies (2b, 7b) lengthwise of the belt is set at about 20–60% of the diameter of the straight type end rollers (15). Even when the conveyor belt is installed taut between small-diameter end rollers, long-term use is possible.Type: GrantFiled: November 2, 2004Date of Patent: May 30, 2006Assignee: Nitta CorporationInventor: Naoyuki Saeki

Patent number: 6994208Abstract: An end roller of a curved conveyor has an pivot shaft and a plurality of short rollers rotatably mounted on the pivot shaft. A bearing with an outer race of a larger outer diameter than the outer diameter of the short roller is interposed between at least the adjacent short rollers located near an outer peripheral side of the belt. A bearing having an outer race of the same size outer diameter as the outer diameter of the short rollers may also applicable. Frictional noises from the end rollers during the rotation of the conveyor belt may be suppressed.Type: GrantFiled: May 7, 2002Date of Patent: February 7, 2006Assignee: Nitta CorporationInventor: Naoyuki Saeki

Patent number: 6899220Abstract: In a curved conveyor with end rollers disposed at a certain angle between which a belt body is stretched, a plurality of bead constituting elements is detachably disposed along the outer peripheral end of the belt body. Alternatively, in a linear conveyor with end rollers disposed in parallel between which a conveyor belt body is stretched, a plurality of bead constituting elements is detachably disposed along both ends of the belt body. In these conveyor belts, only damaged bead constituting elements may be readily replaced.Type: GrantFiled: May 8, 2002Date of Patent: May 31, 2005Assignee: Nitta CorporationInventor: Naoyuki Saeki

Patent number: 6866141Abstract: A joining line from a portion of a belt caught and held between a driving roller and a pinch roller and the vicinity thereof to an outer peripheral end of the belt is a single straight line or a gentle curve having a large angle with respect to a tangent to a belt peripheral line. The joint of the other part of the belt is made by a finger joint. Alternately, a joining part from a portion of a belt caught and hold between a driving roller and a pinch roller and the vicinity thereof to an outer peripheral end of the belt is made with a finger joint with widely pitched fingers, while another joining part of the rest of the belt are made with a finger joint with narrowly pitched fingers. Peeling or breakage at the joining parts for a long time, and a thick joining part are eliminated. And low cost production is achieved.Type: GrantFiled: May 7, 2002Date of Patent: March 15, 2005Assignee: Nitta CorporationInventor: Naoyuki Saeki
