The cover unloading device 60 receives the container cover 20 by the receiving device 30 and carries the container cover 20 to move after the cover unloading work is finished at the first station, so that the cover unloading device 60 does not need to leave the first station, the reciprocating time of the cover unloading device can be saved, and the conveying device 50 is positioned at one side of the cover unloading device 60, so that the operation of receiving and conveying the container cover 20 by the conveying device 50 is carried out at a position outside the first station, the cover unloading device 60 can be put into the next round of cover unloading work after the receiving device 30 leaves, the interval time is short, and the cover unloading efficiency is improved.

Further, the cover-pulling device 40 is configured to pull the container cover 20 off the receiving device 30 by relative movement with the receiving device 30. Compared with the scheme of grabbing, moving and putting down the container cover 20 again, the transfer mode of pulling the container cover 20 off the receiving device 30 by using the relative motion of the cover pulling device 40 and the receiving device 30 is simpler in structure, the number of the container covers 20 pulled off at one time can be more, the operation is more direct, rapid and effective, and the efficiency is higher.

Specifically, when the container cover 20 is pulled down, the receiving device 30 can be kept still, and the cover pulling device 40 moves relative to the receiving device 30; alternatively, the cover-pulling device 40 remains stationary and the receiving device 30 moves relative to the cover-pulling device 40; alternatively, both the receiving means 30 and the means for removing the cover 40 may move relative to the ground, but at different speeds or directions, i.e. the receiving means 30 and the means for removing the cover 40 have a relative movement.
