The bag portion 164 shrinks inside the material collection tube 163. When collecting materials, the bottom end of the material collection tube 163 is inserted into the threaded hole of the nut. After that, compressed air is introduced into the hollow cavity 104, and the bag portion 164 expands from the inside of the material collection tube 163. The bag portion 164 fills the gap between the nut and the material collection tube 163, and fixes the nut at the bottom position of the material collection tube 163, driving the nut to be transferred to the mold.

It is arranged at the outer side of the arranged nut picking and placing mechanism 16. Then, compressed air is introduced into the inside of the picking mechanism 10. The compressed air makes the bottom end of the nut picking and placing mechanism 16 expand, and then the bottom end of the nut picking and placing mechanism 16 is used to expand in the hole of the nut to grab it. Then, the picking mechanism 10 is lifted to the set height, and the mobile crane 3 moves the grabbed nut to the top of the mold 11.
