After the carton is detected to be in position, the carton conveyor line 1 stops. Step 2: The centering mechanism 8 clamps the carton and pushes it to the middle of the carton conveyor line 1, and the lifting mechanism 10 lifts the carton. Step 3: When the empty pallet reaches the end of the pallet conveyor line 2, the laser sensor 11 detects that it is in place and the blocking mechanism 9 stops it.
