(3) the unloading operation is carried out to unloading mechanism, specifically does: the unloading manipulator will get rid of and move to Tray dish platform to one side film in the carrier, and moving mechanism carries out empty dish replenishment operation to Tray dish platform.
10. The method of claim 9, wherein the operation of supplementing the hollow disc in step (3) specifically comprises:
A. placing a stack of empty Tray trays at the empty Tray storage location; the blanking manipulator carries out blanking operation, and a film is put into the empty Tray of the transfer platform to form a full Tray; the transfer platform bearing the full Tray descends to the full material level;
B. the third lifting cylinder lifts a plurality of full Tray discs placed at the full Tray storage position, the lifting is stopped when the sensor assembly detects that the lowest full Tray disc reaches a specified position, the second cylinder pushes the full Tray discs on the transfer platform to the full Tray storage position to complete the full Tray storage operation, and the transfer platform rises to the blanking position again;
C. the first material pushing structure pushes the Tray disc at the bottom of the stack of empty Tray discs to the transfer platform at the material discharging position, and the empty disc supplementing operation is completed.
