1. A shaft-shaped component supply device comprising:
a component supply pipe that transfers a shaft-shaped component made of magnetic material;
a supply rod configured to perform advancing and retracting movement; and
an outer cylinder that houses the supply rod; wherein
the component supply pipe and the outer cylinder are coupled to each other at an acute intersection angle,
the supply rod is configured to advance while holding the shaft-shaped component at a distal end of the supply rod and release the shaft-shaped component at a target location,
the component supply pipe has an outlet hole opened towards the distal end of the supply rod, the shaft-shaped component being transferred from the outlet hole to the distal end of the supply rod by an attraction force of a magnet,
the component supply pipe is arranged with a holding piece that opens and closes the outlet hole in an advanceable and retractable state,
the supply rod includes an inner shaft having a distal end with another magnet, the another magnet being configured to attract the shaft-shaped component, and a hollow shaft having the inner shaft inserted therein so as to be able to slidably retract in the hollow shaft, and
the shaft-shaped component supply device further comprises:
a first drive means configured to advance and retract the holding piece;
a second drive means configured to pull back the another magnet of the inner shaft in a direction away from the distal end of the supply rod; and
a single holding member mounted at a distal end part of the outer cylinder, the first drive means and the second drive means being coupled to the single holding member so that the first drive means and the second drive means are arranged to protrude only on one side of a virtual plane including a center axis of the component supply pipe, a center axis of the supply rod and a center axis of the outer cylinder.
