Abstract:
1. A transport method comprising: transporting a thin plate-shaped to-be-transported object to a transport destination in a horizontal posture by a transport robot having a hand comprising stationary clamp members which are capable of coming into contact with a periphery of the to-be-transported object, and a movable clamp member which is pressed into contact with the periphery of the to-be-transported object to thereby pinch the to-be-transported object between the stationary clamp members and the movable clamp member; thereafter lowering the hand in a state of having moved the movable clamp member backward to an unclamped position out of contact with the periphery of the to-be-transported object, thereby transferring the to-be-transported object onto a plurality of supporting pins disposed in the transport destination, wherein the improvement comprises moving the hand in an X-axis plus direction at the time of lowering the hand to transfer the to-be-transported object onto the supporting pins, where a direction of opposing the stationary clamp members to the movable clamp member is defined as an X-axis direction, and a direction from the movable clamp member toward the stationary clamp members is defined as the X-axis plus direction; and subjecting the hand to vibrations in the X-axis direction, at the time of lowering the hand, while moving the hand in the X-axis plus direction.
