Then, the screw S that has been sent under pressure is attached to the screw receiving portion 4.
It is determined whether or not the sheet is stored in No. 6 (step S4).
The screw detection sensor 49 determines whether or not it is stored. That is, when the screw sensing sensor 49 senses the screw S after the pressure feeding solenoid valve 30 is turned on to start the pressure feeding of the screw S, it is determined that the screw S is housed in the screw receiving portion 46 (YES). On the other hand, when the screw detection sensor 49 does not detect the screw S even after a fixed time (about 5 seconds) has elapsed after the screw S has been pressure-fed by the time management of the screw detection sensor 49, the screw S receives the screw. It is determined that it is not stored in the unit 46 (NO).

When it is determined in step S4 that the screw S is not stored in the screw receiving portion 46, the pressure feeding of the screw S is stopped and the screw S is sucked into the screw storing portion 26 (step S5). At this time, the pressure feeding electromagnetic valve 30 is turned off (see FIG. 6), and the supply of the pressure feeding air to the screw storage portion 26 is stopped, and at the same time, the suction electromagnetic valve 29 and the pressure feeding electromagnetic valve 48 are turned on. In this state (see FIG. 6), the vacuum ejector 28 is in a suction state, and the pressure receiving air toward the holding block 25 is supplied to the screw receiving portion 46 via the connecting pipe 47.

Therefore, since it has a retry mechanism which repeats pressure feeding / suction of compressed air, for example, the screw S is pressure-fed in an inclined state or is caught by the tube receiver 51 and does not reach the screw receiving portion 46. Or, even if the screw S reaches the screw receiving portion 46, the screw S is inclined and does not maintain the posture in the vertically installed state.
In the case where the sensor S does not store the compressed air and the sensor S does not detect the screw S, the compressed air is repeatedly pumped and sucked until the screw S is housed in the screw receiving portion 46.

Therefore, the screw S housed in the screw receiving portion 46 is positioned immediately below the tip of the driver bit 13a (see FIG. 9C). Then, the screw S is held by the driver bit 13a (step S8). At this time, the catcher solenoid valve 44 remains in the ON state (see FIG. 6), the piston 42a is in the advanced state (see the chain double-dashed line in FIG. 2), and the suction solenoid valve 55 and the pressure feeding solenoid valve 48 are When in the ON state (see FIG. 6), the vacuum ejector 54 is in the suction state, and the pressure-feed air toward the automatic driver 13 is supplied to the screw receiving portion 46 via the connecting pipe 47.

Next, after confirming that the automatic driver 13 has sucked the screw S, the catcher 45 is attached to the tube receiver 51.
(Step S9). At this time, the catcher solenoid valve 44 and the pressure feeding solenoid valve 48 are in the OFF state (see FIG. 6), the piston 42 a is in the retracted state (see the solid line in FIG. 2), and the pressure feed air to the screw receiving portion 46 is Supply is stopped. The suction solenoid valve 55 remains in the ON state (see FIG. 6).
