なつている。 Conventionally, an automatic screw tightening device has a configuration as shown in Figs. 1 and 2, and an automatic screw feeder 2.
The screw 23 supplied from 1 through the air shooter 22 is received by the screw receiving arm 25 disposed at the screw outlet 24 of the shooter, and is sent to the screw suction pipe 26 side by the movement of the screw receiving arm. There is a screwdriver 2 inside the screw suction pipe.
7 is provided to be rotatable and movable up and down, and the screw 23 that is attracted is held at the correct position at the tip of the driver, and the screw receiving arm 25 is retracted. The suction pipe 26 and the driver 27 are lowered together,
The object 29 to be assembled, which has been transported by the conveyor 28 and stopped at a predetermined position, reaches a screw-fixing position. In this state, only the suction pipe is slightly raised, and the screwdriver is rotated to automatically tighten the screws.

Reference numeral 4 denotes a screw suction pipe, which is adapted to suck the screws supplied to the suction port 6 through the air vacuum hose 5. Reference numeral 7 denotes a driver provided in the screw suction pipe 4 so as to be rotatable and movable up and down; 8 is a support plate;
is supported so that it can be raised and lowered within the hole 8a,
Further, a shooter 9 for supplying screws is fixed to the support plate 8 on the side of the screw suction pipe 4. 10 is a screw 11 supplied from the shooter 9
A screw receiving part 10 which is a screw receiving arm that receives the screw and is fitted with the threaded part of the screw facing downward.
It is equipped with a. The screw receiving arm 10 is a fulcrum 12
It can be rotated around , and after transferring the screw 11 supplied to the screw receiving part 10a to the suction port 6 of the screw suction pipe, it returns to its original position. 13
1 is an air cylinder for driving the screw receiving arm 10, 13a is a piston, 13b is an air pipe, and 14 is a spring for returning the screw receiving arm. 15 is a screw discharge port of the shooter 9, and a notch 16 is provided on one side of the discharge port, that is, on the side of the suction port 6. Further, a screw receiving plate 17 is arranged below the screw receiving arm so as to correspond to the screw discharge port 15. The surface of this plate 17 is inclined in the opposite direction from the notch 16 side, that is, so that it is lower in the opposite direction to the moving direction of the screw receiving arm 10,
Furthermore, a screw receiving groove 18 is formed along the inclined surface into which only the threaded portion of the screw is inserted.
Next, an explanation will be given based on FIG. 7 of an example of the operation of the above-mentioned configuration. Even if an unnecessary succeeding screw 11' is supplied from the shooter 9 to the regular screw 11 as shown in (a), (b) ) and (c), when the screw receiving arm 10 moves, the screw 11' falls over without getting caught due to the presence of the notch 16, and (d)
~ As shown in (f), the screw 11' is attached to the screw receiving arm 1.
As the screw moves, the head of the screw always faces downward and falls onto the plate 17. Furthermore, the screw 11' falls in the counterclockwise direction using the screw head as a fulcrum, and only the threaded portion enters the screw receiving groove 18 of the plate 17, and the head is locked to the groove edge 18a. Locked screw 1
As shown in (g), when the screw receiving arm 10 returns, the head of the screw receiving arm 10 is pushed and aligned along the screw receiving groove 18 of the plate 17, and when a large number of screws are retained, it is recovered.
