PROBLEM TO BE SOLVED: To dispense with complicated control such as a zero correction, while reducing a height dimension of a carrier conveyor.SOLUTION: A centering device comprises a table 20, a rotary roller 21 supported by the table 20, lifting means 22 for lifting the table 20 and first and second pushers 23 and 24 for pressing both sides of a pallet P by the movement of movement parts 230 and 240, and (a) when the pallet P is placed under the table 20, the table 20 is lifted by the lifting means 22, and the pallet P is freely moved in a lateral direction 1b by the rotary roller 21, (b) the movement part 230 of the first pusher 23 is pressed to the pallet P, and the pallet P is moved by a first moving distance (m), and the pallet P is applied to the second pusher 24, and a second moving distance (n) is set to 1/2 of the first moving distance (m), and (c) the pallet P is pressed by the second pusher 24, and the pallet P is moved by the second moving distance (n), and the pallet P is centered. |
