Subsequently, referring to steps (c) of FIGS. 4A and 4B, the first wheel nut 10-1 continues to slide down even after step (b) so that the head first exits the alignment tube 151. At the same time, when the alignment slide 140 is moved to the left as opposed to step (b) again, the position of the supply pipe inlet 141a becomes adjacent to the position of the outlet 122b of the transfer part guide part 121 and the slide plate The second wheel nut 10-2, which was blocked by 142 and maintained in a stopped state, falls and flows into the supply pipe 141.

In this way, the second wheel nut 10-2 introduced into the supply pipe and the wheel nuts continuously supplied to the alignment unit 130 through the rear guide portion also undergoes the alignment process of steps (a) to (c), and the second alignment is performed. Will come true.

Subsequently, FIGS. 5A and 5B are diagrams illustrating an alignment state according to the operation of the alignment unit when the head of the wheel nut faces upward.

5A and 5B, the nut hole of the first wheel nut 10-1' located at the front of the plurality of wheel nuts 10-1', 10-2', 10-3'... In other words, the alignment process in the case where the head of the first wheel nut faces upward and is supplied from the transfer unit to the alignment unit will be described as follows.

First, referring to step (a) of FIGS. 5A and 5B, in the first wheel nut 10-1 ′ is supplied from the transfer unit 120 through the alignment unit 130 to be aligned, the alignment slide When the position of the inlet (141a) of the supply pipe (141) of 140 is slid to contact the position of the outlet (122b) of the guide portion 121,

One of the first wheel nuts 10-1 ′ located at the most front is introduced into the supply pipe 141 of the alignment slide 140.

At this time, since the length (g) of the supply pipe 141 is formed to correspond to the length (L) of the wheel nut 10, the rear wheel nut 10-2 adjacent to the front wheel nut is automatically aligned with the alignment slide ( 141), but only one flows in.

Subsequently, referring to steps (b) of FIGS. 5A and 5B, when the alignment slide 140 moves to the right in the opposite direction to step (a), the position of the supply pipe inlet 141a is positioned at the transfer part guide part ( The second wheel nut 10-2 ′ that is out of the position of the discharge port 122b of 121 and is blocked by the slide plate 142 is maintained in a stopped state.
