Title: Curved belt conveyor
Inventor: KANDA TORU
IPC: B65G15/02
Filed: 2001-12-07
Abstract: <P>PROBLEM TO BE SOLVED: To provide a curved belt conveyor capable of preventing slipping of a belt for conveyance in the central direction without marring it.  <P>SOLUTION: Movement of the belt 13 for conveyance to the circular arc central side is prevented by giving outward force by pulling the circular arc central side of the belt 13 for conveyance by extending the circular arc central side by moving an axis of rotation 15 of a roller 12. Additionally, it is possible to prevent movement of the belt 13 for conveyance to the circular arc central side as resistance at the time when the belt 13 for conveyance moves to the circular arc central side increases since a circular arc central side end part of the roller 12 makes contact with the neighborhood of the circular arc central side end part of the belt 13 for conveyance in the case when a small diametrical part 18 is provided on the roller 12.  <P>COPYRIGHT: (C)2003,JPO
