Transport device for electrode double packaging device, and electrode double packaging device comprising same

An electrode double packaging device comprising:

• an electrode roll supply part for supplying an unpackaged electrode roll;
• a first packaging bag supply part for supplying a first packaging bag to a primary packaging location;
• a second packaging bag supply part for supplying a second packaging bag of a material different from that of the first packaging bag to a secondary packaging location;
• a first transport device for transporting the unpackaged electrode roll;
• a first packaging part for primarily packaging the unpackaged electrode roll transported by the first transport device with the first packaging bag;
• a second transport device for transporting the primarily packaged electrode roll;
• and
• a second packaging part for secondarily packaging the primarily packaged electrode roll transported by the second transport device with the second packaging bag,
• wherein the second transport device comprises:
• a seating part having a seating groove on which the primarily packaged electrode roll is seated;
• a moving part connected to the seating part for moving the seating part;
• a packaging bag arrangement part provided to move together with the seating part by the moving part, and for closely attaching the first packaging bag to the electrode roll side when moving;
• and
• a control part configured to perform a seating mode for controlling the moving part to move the seating part so that the electrode roll is seated in the seating groove, and a transport mode for transporting the seating part, on which the electrode roll is seated, to the secondary packaging location.
