来る（図５（イ）参照）。Operation of the Embodiment Next, the operation of the embodiment will be described. After receiving the spring semi-finished product S1 manufactured from the spring manufacturing machine with the holding tool 10 in the upright state, it is laid down to face the spring semi-finished product S1 to the spring discharge port 5. After that, when the spring S2 is completed,
That is, when the upper hook H, which has been horizontal, is raised by the hook raising device (not shown), the holding piece 11 opens, and the spring S2 falls to the rear end of the chute 14 and moves back and forth in the longitudinal direction. In a position facing the direction, the chute 14 slides and projects from the front spring outlet 16. Before that, the position where the holding piece 30 is connected to the chute 14, that is,
Since it has moved to the spring receiving position 18 and is on standby, the spring S2
Is placed on the holding piece 30. At that time, the pusher 34 receives the spring S2 while retracting (moving forward) with respect to the holding piece 30, that is, the spring S2 while absorbing the impact generated when the spring S2 hits the pusher 34. Therefore, when the spring S2 hits the pusher 34, the spring S2
It is possible to quickly damp and stop the minute vibrations that occur in the (Fig. 5 (a)).

Project a predetermined length toward the spring S2, and attach the spring S2 to the spring contact piece 3
6 to the hanging part 36a. In that state, the interval sensor 39 detects the gap m1 between the hanging portion 36a and the detection head 40.
Can be measured, and as a result, the length m3 of the spring S2 can be detected. That is, as shown in FIG. 5C, from the detection head 40, [m1 + m2 (thickness of the hanging portion 36a) + m3
(Setting reference free length of spring S2)] If the spring pushing surface of the pusher 34 is located at a position separated by a distance of [], the free length of the spring S2 can be detected by measuring m1. (See FIG. 5C). Spring S2
The rear end of the rear hook H (the tip of the curved portion) and the detection head 4
When measuring the gap with 0, the detection head 40 at the rear end (the tip of the curved portion) of the rear hook H depends on the direction of the hook H.
The position relative to the detection head 40 is slightly deviated, so that the measured value of the gap between the rear end of the rear hook H (the tip of the curved portion) and the detection head 40 is likely to vary. Since the gap m1 between and is measured, there is no such problem.

The spring S2 is discharged from the non-defective product outlet 44. On the other hand, if the non-defective product spring S2 is not within the free length within the allowable error range, the opening / closing member 46 closes the non-defective product outlet 44 based on the defective product signal generated by the interval sensor 39. Since 45 is opened, the spring S2 of the defective product is discharged from the defective product outlet 45 by opening the holding piece 30.
