1a, 12a). Next, the rotating roller table 17
The swing table 17b is rotated about the shaft 17a by the air cylinder device 17d and closed on the shaft S, and the rotating roller 17c contacts the shaft S. Rotating roller 17
Since c is rotationally driven, the shaft S is rotationally driven about its axis. Before and after the rotation is applied to the shaft S, the axial positioning tables 15 and 16
Is moved to a predetermined position in the axial direction to determine the axial position of the shaft S.

When measuring the diameter of the rotationally driven shaft S, the steady rest 13 rises to bring the shaft S into contact with the support groove 13a, thereby suppressing its run-out. In this state, the photoelectric measuring device 14 measures the diameter of the shaft S at a predetermined position, for example, at two different positions in the axial direction. As described above, this measurement is performed a plurality of times during one rotation of the shaft S, and an average value is obtained. Shaft S by the steady rest 13
The reason for suppressing the fluctuation is to make the measurement accurate and to facilitate the data processing.

Next, when measuring the shake, the steady rest 13 is lowered, and the shaft S is freely rotated based on the butt side. The axial positioning table 16 is separated from the shaft S. In this state, the photoelectric measuring device 14 is moved to a predetermined position in the axial direction of the shaft S, and the shake amount of the shaft S is measured.

The measured values of the diameter and the runout are stored in the memory.

When the measurement at the diameter and deflection amount inspection stage 10 is completed, the gripping hand 56 of the shaft transfer robot 50 grips the shaft S on the inspection stage 10 and moves upward to move it on the deflection amount inspection stage 20. The shaft S is further lowered to position the shaft S on the fixed support 21. In this state, the movable support base 22 moves forward, and its upper arm 22a is located above the shaft S, and the butt side of the shaft S is held between the fixed support base 21 and the movable support base 22. At the same time, the weight 23b at the raised position by the first air cylinder device 23a and the load applying arm 23d at the raised position by the second air cylinder device 23c are
With the first air cylinder device 23a, it advances toward the shaft S, and the load applying arm 23d is positioned above the shaft S at a predetermined position on the tip side of the shaft S (FIG. 9). When this setting is completed, the gripping hand 56 of the shaft transfer robot 50 opens the shaft S and rises,
It again moves to the standby position above the diameter and shake amount inspection stage 10.

When the setting of the shaft S is completed,
The load applying arm 23d is provided by the second air cylinder device 23c.
Is lowered to contact the shaft S, and the height position of the load applying arm 23d at this contact position is measured by a non-contact type deflection measuring device 24.
To determine the origin position (FIG. 10). Next, the first
The weight 23b is lowered (free) by the air cylinder device 23a, and the shaft S is bent. In this case, the amount of deflection from the origin position is also the non-contact type deflection measuring device 2
4 and stored in memory. The first air cylinder device 23a and the weight 23b are guided by a guide (not shown) so as not to be inclined in any state.

When the above measurement at the deflection inspection stage 20 is completed, the gripping hand 57 of the shaft transfer robot 50 descends to grip the shaft S, and the movable support 2
2. The load applicator 23 returns to the standby position. When the gripping hand 57 grips the shaft S on the deflection amount inspection stage 20, another gripping hand 56 grips the next shaft S for which the measurement of the diameter and the deflection amount has been completed on the diameter and deflection amount inspection stage 10. . Thus, inspection stage 1
The shaft transfer robot 50 gripping the shaft S on the inspection stage 20 with the gripping hand 56 and gripping the shaft S on the inspection stage 20 with the gripping hand 57 then rises, and moves the gripping hand 56 above the inspection stage 20, The gripping hand 57 moves so as to be located above the discharge stage 30, and descends again. Then, the gripping hand 57 is connected to the discharge stage 30.
The shaft S is simply opened and dropped above the gripper, and the gripping hand 56 is moved to the bending amount inspection stage 2 as described above.
Set the shaft S on 0. When the set is completed,
The shaft transfer robot 50 is restored to the standby position where the gripping hand 56 is located on the inspection stage 10 and the gripping hand 57 is located on the inspection stage 20.

The shaft S dropped on the discharge stage 30
Is guided on a feed conveyor 32 by an inclined guide 31 and sent to a separation / extraction stage 40 by the feed conveyor 32. In the separation take-out stage 40, the shaft S
It is fed by the feed conveyor 42 and the feed guide 43 until it comes into contact with the stopper 41. At this feed end, the separation / extraction robot 60 takes out the shaft S separately into good and defective products. That is, the gripping hand 68 of the separation / extraction robot 60 descends on the shaft S that is in contact with the stopper 41, grips the shaft S, and rises. Then, the shaft S that has been advanced to the non-defective product stocker 61 and the defective product stocker 62 and determined to be defective in any of the above-described diameter, deflection amount, and deflection amount is determined to be a defective product stocker 62 and both are determined to be non-defective products. The dropped shaft S is dropped on the non-defective stocker 61. Hereinafter, the same operation is repeated.
