[0002] In the pipe material processing workshop, pipe materials are usually placed in the material rack for temporary storage. When they are needed, they often need to be taken out from the material rack manually and put on the machine, which is inefficient. When the pipe material is taken out from the material rack, it is often necessary to lift the pipe material. The manipulator can take the pipe material out of the material rack and put it on the machine. However, since the material taking position of the manipulator is relatively fixed, the positioning problem of the pipe material must be solved so that the pipe material can automatically fall into the fixed position for the manipulator to take the material. Summary of the invention

[0031] S2. The lifting frame 3 is lifted under the drive of the lifting drive mechanism. During the lifting process, the pipe material will be lifted by the lifting frame 3 and leave the original supporting step 21.

[0032] S3. When the lifting frame 3 is lifted to the highest point, the height of each lifting step 31 will be raised by one level.

[0034] S5. After the blocking block 51 is retracted, the pipe material moves along the slope of the third supporting step 21 to the receiving groove 6.
