Swing 12A downward.

Next, as shown in FIG. 12, the valve guide 11 is
c and 11d to the first and second receiving parts 313 and 314. first and second sending rods 261,
262, the intake valve valve guide 11
c is a protruding piece 321, chuck claws 323, 323, and the exhaust valve valve guide 11d is a protruding piece 331,
Guided and held by chuck claws 333, 333,
In the embodiment, eight valve guides 11a for intake valves and eight valve guides 11d for exhaust valves are each held. After the valve guides 11c and 11d are transferred to the first and second receiving parts 313 and 314, respectively, the cylinder 53 is contracted, and the swing arm 112A is
is made into an upright position by the extension operation of the cylinder 141.

Next, as in the case of the supply device 6, as shown in FIG. 8, the valve guides 11c and 11d for intake valves and exhaust valves are supplied to the respective press-fit rods 201 and 202 by the supply mechanism 15A.

Therefore, according to this embodiment, a plurality of bases 4 and 5 are provided on the base 1 so as to be movable in a direction intersecting the direction of the parts supply location, and each base 4 and 5 is provided with a supply mechanism whose stroke can be freely set. 15, 15A, as well as a removable conveyance path and parts delivery mechanism, it goes without saying that each supply device can be easily adapted to different models of valve guides 11a to 11d. By providing parts receiving sections and transport passages that correspond to the model, valve guides compatible with all models can be efficiently and automatically supplied.

(Effect of the invention) As is clear from the above explanation, according to the present invention,
Various parts compatible with multiple models can be efficiently and automatically supplied.
