The conveying directions of the first conveyor line 13 and the second conveyor line 23 are opposite, that is, the loading station 11 and the unloading station 21 can be spaced apart in the first direction.

[0061] It can be understood that the loading docking station 12 and the unloading docking station 22 are used for the docking transition between the loading and unloading of the cleaning basket and the handling and transfer of the manipulator 52. The cleaning basket is transported to the loading station 11 by the overhead crane. The loading station 11 is provided with a first guide limit device for guiding the limit when the cleaning basket is suspended and an overload alarm device 111 for detecting the load. When the load exceeds a first preset value (for example, the first preset value is 200 kg), the first conveyor line 13 stops transporting and alarms. A first detection sensor is provided on the loading docking station 12. When the cleaning basket is When the basket is transported to the first preset position (the grabbing position of the robot 52), the first conveyor line 13 stops running to avoid excessive conveyance of the cleaning basket.
