When the driving unit 441 is operated, the plate 442 enters the alignment area Ca. The plate 442 is positioned above the electrode Sa positioned on the uppermost layer. Thereafter, the controller 450 may lower the loading plate 520 (S300) and discharge the full magazine 500 (S400). Next, a new magazine 500 is inserted (S500). (450) raises the loading plate 520 again (S600)

FIG. 11 is a diagram illustrating a state in which electrodes are temporarily mounted on a plate of a jig, and FIG. 12 is a plan view of a plate in which electrodes are temporarily mounted.

Referring to FIGS. 11 and 12, during the process of replacing the full magazine 500, the electrode Sa is temporarily loaded on the plate 442 of the jig 440. The temporarily loaded electrode Sa is aligned through the first alignment unit 420 and the second alignment unit 430 (S700). In particular, as shown in FIG. 7, the second alignment unit 430 The second moving part 433 moves along the slot 1 of the plate 442 of the jig 440 and contacts the front or rear surface of the temporarily loaded electrode Sa.

13 is a view showing a state in which the magazine is replaced and the loading plate is in contact with the lower surface of the plate, and FIG. 14 is a view showing the upper surface of the groove of the loading plate according to the modification when the magazine is replaced and the lower surface of the second part of the plate Fig. 15 is a view showing a second part of the plate disposed in the groove of the loading plate, Fig. 16 is a side view showing a retracting plate, and Fig. 17 is a plan view showing a retracting plate to be.

When the second signal is input, the control unit 450 retreats the jig 440 from the alignment area Ca (S800). The second signal is a signal in which the replacement of the magazine 500 is detected. Specifically, referring to FIGS. 13 to 15, when the lifting jig 510 of the new magazine 500 moves upward and the loading plate 520 is positioned in the alignment area Ca, a second signal is generated. It is transmitted to the control unit 450. When the loading plate 520 is positioned in the alignment area Ca, the second part 442B of the plate 442 of the jig 440 is positioned in the groove 521 of the loading plate 520. Alternatively, the upper surface of the loading plate 520 abuts against the lower surface of the plate 442 of the jig 440. In addition, the loading plate 520 mounts the lower surface of the electrode Sa disposed on the lowermost layer.

6, 16, and 17, when the second part 442B of the plate 442 of the jig 440 is positioned in the groove 521 of the loading plate 520, the second part 442B The upper surface 4 of is disposed lower than the upper surface of the loading plate 520. Therefore, while the mounting plate 520 supports the lower surface of the electrode Sa disposed on the lowermost layer, the second part 442B is naturally separated from the electrode Sa. When the upper surface of the loading plate 520 supports the lower surface of the electrode Sa disposed on the lowermost layer, due to the height difference between the upper surface of the loading plate 520 and the upper surface 4 of the second part 442B, This is because a space is generated between the lower surface of the electrode Sa and the upper surface 4 of the second part 442B.

The control unit 450 operates the driving unit 441 to move the plate 442 back in the alignment area Ca. At this time, since the second part 442B is separated from the electrode Sa, the plate 442 can be retracted to its original position without damaging the electrode Sa. Thereafter, the electrodes Sa are directly loaded on the loading plate 520 until the magazine 500 is full. If this process is repeated, there is an advantage that it is possible to replace the full magazine 500 without stopping the electrode production line. In addition, in order not to stop the electrode production line during the replacement process of the magazine, a multi-stacking device is not implemented, and the full magazine 500 can be replaced without stopping the electrode production line with only one stacking device.

In the above, specific embodiments of the stacking apparatus of the secondary battery electrode production system and the stacking method of the secondary battery electrode production system of the present invention have been described, but various implementation modifications are possible without departing from the scope of the present invention. Is self-explanatory.

Therefore, the scope of the present invention should not be limited to the described embodiments, and should not be defined by the claims to be described later, as well as the claims and equivalents.
