PURPOSE:To automatically perform loosening and removing work of fastener parts, by providing a rotatable loosening member which loosens the fastener parts of bolt or screw and the like for building an article. CONSTITUTION:When articles 5, set by a bolt 6 are supplied to the lower, a catcher mount 16 is lowered to a fixed position, and the point end of a pressing rod 22 is adapted to the bolt 6, then the rod is moved backward against a compression spring 23. Because a shaft 24 is in rotation, a head part of the bolt 6 is fitted to an end hole of a socket pit 21, and the bolt 6 is loosened. Then a driving shaft 20 and the socket pit 21 are lifted against a compression spring 26 for a nose 18, while a leg part of the loosened bolt 6 is held to a jaw 17, and the catcher mount 16 is lifted. Further a fastener part loosening and removing unit is horizontally moved, and then the driving shaft 20 and the socket pit 21 are lowered to open the jaw 17 and release the bolt 6. |
