PURPOSE:To simplify the structure and to reduce the occupied space by rotating a pinion to slide a movable frame with respect to a fixed frame through a rack, and moving a pallet through a belt with the movement. CONSTITUTION:When a shaft 3 is rotated, a pinion 5 is rotated to transmit torque to a rack 9, so that a movable frame 8 supported on a fixed frame 1 by a roller 7 is moved in direction of B. With the movement, a pinion 13 is rotated in engagement with a rack 6 to rotate a tail shaft 11 and a tail pulley 12. A belt 15 is moved in direction of B' by rotation of the tail pulley 12, and a pallet 16 is moved at uniform speed. At this time, the shaft 3 is rotated by a motor 21 through a belt pulley 4, and the timing of moving and stopping the movable frame 8 is controlled. If there is a moving load receiving mechanism in an area F, the movable frame 8 is retreated to a position in the fixed frame 1. |
