Accordingly, it is an object of the present invention to provide a transport device for a shaft-shaped component that can reduce manufacturing costs.

"Means for Solving the Problem" The gist of the present invention for achieving such an object is to: 1 In a device for transporting a shaft-shaped component to position and deliver the shaft-shaped component to a predetermined location, A pair of claw members that are opened and closed in a direction orthogonal to the axial direction and gripped, and are biased in a closing direction, an opening and closing mechanism that drives the pair of claw members to open and close, and a vertically movable support on the device body. And a location member for interlocking and releasing the pair of claw members when moving downward and for fitting the shaft-like component from above to position the shaft-like component. A device for transporting shaft-shaped parts.

2 At least one of the pair of claw members is formed as a claw having two or more stages, and the other claw member is arranged so as to enter the gap between the claws of each stage of the one claw member, and the opening / closing mechanism is
The shaft-like component according to claim 1, characterized in that the shaft-shaped component comprises a rack member connected to each of the pair of claw members, and a pinion that meshes with the rack member and is rotatable forward and reverse to open and close the pair of claw members. It exists in the carrier device.

"Operation" The shaft-shaped component is gripped by the pair of claw members and conveyed to a predetermined place. At this time, the location member is in the upper position.

When the shaft-shaped component is conveyed to the predetermined place, the location member moves downward. This causes the pair of claw members to open a small amount against the biasing force and release the grip, so that the shaft-like component can be moved.

Further, when the location member moves downward, the shaft-shaped component is appropriately moved and positioned so as to be fitted to the shaft-shaped component.

In the case where the pair of claw members are formed in two or more stages of claws, for example, if the tip of the claw member is a V-shaped groove,
When closed, the other claw member enters the gap between the claws of each step and does not interfere with each other, so that even a shaft-shaped component having an extremely small diameter can be reliably gripped.

Further, in the one in which the opening / closing mechanism is configured by the rack member and the pinion, when the location member moves downward, for example, if the pinion rotates, the pair of rack members move, and thereby the pair of claw members. Is opened and the grip is released.
