[0069] Further, after the grabbed material is grabbed, the first moving part 72 and the second moving part 73 are driven again, the first moving part 72 and the second moving part 73 drive the device and the material to move to the designated stacking area, then the first driving part 52 drives the support 41, the grabbing part 422 and the material to move downwards, then under the drive of the second drive motor 425, the two grabbing parts 422 rotate away from each other and release the material, finally under the drive of the first drive motor 453, the support 41 and the next adjacent grabbing part 422 rotate relative to the fixed column 31, and under the drive of the second drive motor 425, the two grabbing parts 422 rotate away from each other and release the material, and the materials are stacked in turn.

[0070] The device can solve the technical problem that the material carrying efficiency is low in the prior art because the material taking device arranged at the left end of the lifting mechanism can only grab or take a single material at a time.

[0071] The specific implementation method of the utility model described above does not constitute a limitation on the protection scope of the utility model. Any various other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
