After the filter frame 1 is pulled out to the right position and locked by a locking mechanism on the AGV transport vehicle, the AGV transport vehicle bears the filter frame 1 again to replace the carton filter 11 in the carton replacing area. While another AGV transport carries the filter frame 1 with the new carton filter automatically navigated to the position requesting the replacement. After the filter frame is transported in place, the filter frame 1 is unlocked by a locking mechanism on the AGV transport vehicle and is pushed into the filter box body 2 by using a tool clamp. After the filter frame 1 has been advanced into position, the rotary clamping device 26 is rotated again and presses against the rear end sealing plate behind the filter frame, again forming a seal. The air valve 41 in the exhaust duct is opened, ventilation is again established and the paint mist starts to be adsorbed. The automatic replacement process to this replacement position is completed. Then the AGVs start waiting for the next change request.
