The working principle of the transfer stacking system is as follows:

after the aluminum rings 24 are produced in the pit 28, the aluminum rings are supported by the pit supporting device 27 and ascend to the exposed pit, the transfer stacker is instructed to move to the position of the pit 28, the pit supporting device 27 is controlled to enable the guide rails 26 on the pit supporting device 27 to be equal to the guide rails 11 on the transfer stacker in height, then the front and rear driving mechanism 16 pushes the sliding seat 12 to move forwards, the portal 2, the fork fixing frame 20 and the forks 3 are driven to move forwards, the sliding seat 12 slowly extends out of the guide rails 11, and the extending part of the sliding seat extending out of the guide rails 11 is supported and guided to move with the guide rails 26 on the pit supporting device 27, so that the portal 2, the fork fixing frame 20 and the forks 3 are supported together with the remaining part. Because three guide rails 11 on the transfer stacker correspond to three guide rails 26 on the pit supporting device 27 one by one, the fork 3 can gradually extend into an inner hole of the aluminum ring 24 in the forward moving process, after the fork 3 reaches a proper position, the front and rear driving mechanisms 16 are controlled to stop running, and then the upper and lower driving mechanisms 5 are started, so that the fork fixing frame 20 and the fork 3 move upwards, the aluminum ring 24 is forked, at the moment, due to the common supporting function of the extending part and the remaining part, the stable support can be formed for the portal 2, the portal 2 is prevented from bearing overlarge torque, the balance and the stability of the transfer stacker are improved, and the safety of the aluminum ring 24 and surrounding operators is further ensured.

The front and rear drive means 16 are then activated, causing the fork 3 to move the aluminium rings backwards, during which there is initially a common support of the projecting part and the remaining part, ensuring the stability of the entire transfer stacker, after which the greater part of the carriage has been retracted onto the guide rail 11, ensuring stability even if it is detached from the guide rail 26. After the slide resets, actuating mechanism resets about the control, and fork mount and fork all move down to initial position, then rise through 7 control backup pad of jacking device 6, and the rotation of backup pad 6 self-adaptation is pasted mutually with the surface of aluminium circle to supplementary fork 3 drags the bottom of aluminium circle, guarantees the stability of aluminium circle in the transportation, avoids the fork to bear too big moment of torsion simultaneously.

Then transport the position that the piling car moved the goods shelves by oneself, earlier made the fork shift up by upper and lower actuating mechanism, then made the slide, portal and fork by front and back actuating mechanism control forward movement, make the extension of slide and the guide rail 30 on the goods shelves support and the direction moves the cooperation, when guaranteeing to stack the aluminium circle on the goods shelves, also supported portal, fork mount, fork and aluminium circle by extension and stay the part jointly, and then guaranteed the balance and the stability of transporting the piling car.
