The motor 3031 is a stepping motor, and the height of the chain 3034 moving under the control of the motor 3031 is matched with the height of a single frame or box to be stacked. When a frame or box enters on each side, the motor 3031 drives the chain 3034 and the carrier 305 to lower by the height of a frame or box, so that the next frame or box entering the door-shaped stacking rack 302 has enough height to be stacked. Two groups of carriers 305 are arranged on each side of the two chains 3034, which can realize continuous stacking work without interruption after a group of frames or boxes are stacked.

The connection shaft of the hinge rod 3061 and the buffer plate 3063 is fixed on the door-shaped stacking rack 302 through a support frame. The buffer plate 3063 extends horizontally to the hollow area of the door-shaped stacking rack 302, and the height thereof is matched with the pushing platform 304. The frame or box entering the door-shaped stacking rack 302 first falls into the buffer plate 3063, and then under the action of the control cylinder 3061, the buffer plate 3063 is controlled to flip downward, so that the frame or box falls into the carrier 305 directly below the buffer plate 3063, thereby achieving the purpose of buffering.

[0038] The utility model discloses a whole process can only need a worker control, still can set up automatic control to whole device, through setting up sensor on push platform 304, buffer plate 3063 and load carrier 305, when inductive position, then, automatically control the next step is carried out.
