<p>A belt curve conveyor in which a guide wheel provided inside of a belt rotates 90 degrees sequentially by the operation of a lock handle, which allows the belt to be removed easily. It comprises a number of guide wheel units (50) mounted on an outer peripheral part of a belt so as to pinch a belt end in which semicircular edges (38, 38) abutting guide wheels (52, 52) are formed on both front and back surfaces of the peripheral part of the belt. Each guide wheel units (50) are composed of a first guide wheel and a second guide wheel abutting an outer edge of a forward belt and a return belt (10), and of a third guide wheel and a fourth guide wheel abutting an inner edge of a forward belt and a return belt (10). The first and fourth guide wheels are supported by a holder (40) provided adjacent to an outer peripheral side plate (8), and the second and third guide wheels are supported by the upper and lower edges of a bracket (45) mounted on the inner centre of the holder in a rotatable manner. Each guide wheels are biased elastically in the peripheral direction by a spacer rubber or a rubber bush (53) engaged in its axis part such that the periphery of a guide wheel opposed to each other come to contact with an edge (38) formed in proximate to the belt outer periphery so as to provide a belt with tension. A lock part (60) is built-in a case 48 accommodating an axis part arranged at the centre of each holder, and a keyhole (61) is formed on the outer surface of the case (480 such that all the second and third guide wheels become separated from the inner surface of the belt in such a manner to sequentially insert a key part (63) of a lock handle into each lock part (60) and to rotate (90) degrees to remove the belt.</p> |
