ZIG FOR INDICATING A SENSING DIRECTION AND METHOD OF SETTING A SENSING DIRECTION USING THE SAME IN TRANSFERRING VEHICLE

摘要

A zig for indicating a sensing direction and a method for setting the sensing direction of a transfer device using the same are provided to sense an optical sensor without a cassette to enable an operator to set the sensing direction of the optical sensor free, thereby controlling the sensing direction of the optical sensor accurately. A method for setting the sensing direction of a transfer device comprises the followings: waiting until a zig for guiding a sensing direction is mounted on the plate of the transfer device(S12); rotating an optical sensor on a plate(S16); scanning an optical sensing signal from the optical sensor to detect the location of a reflection portion of the zig(S20); and rotating the optical sensor to the detected location so that the optical scanning direction of the optical sensor turns toward the reflection portion(S22).
