持するようにしても良い。The above embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, the servomotor is used for driving the rotating disk, but the indexing may be performed by a cam. Further, in the above embodiment, three screw receiving holes 8 with which the screws 1 are engaged are arranged at equal intervals. However, as shown in FIG. But it is good. Further, depending on the size of the distribution table 7, the orientations of the claws 31 and 32 of the screw holding means 3 are directed toward the direction in which the screw 1 is supplied as shown in FIG.
1 may be installed outward so as to open and close. Further, in this embodiment, the rotary disk 7 is provided with the screw holding means 3, but the present invention is not particularly limited to this, and only in the portion where the screw receiving hole 8 in front of the screw guide member 5 is located. The screw holding means 3 is installed and fixed to the gantry 70 side, and the screw guide member 5 is fixed.
May be held only when the screws 1 are transferred to the distributing means 4.

取り出し動作もスムーズになる。As is apparent from the above description, the screw distributing apparatus of the present invention is capable of arranging and feeding screws in a screw feeding means, and a screw discharging device which feeds a screw discharged at a feeding end of the screw feeding means. Dispensing means for receiving one by one and transferring by a predetermined amount, and screw holding means for holding only the screws transferred into the distributing means at the feeding end of the screw feeding means,
The screw holding means has a fixing claw facing the lower part of the screw,
A movable claw provided to be openable and closable with respect to the fixed claw;
An urging means for urging the moving claw in the closing direction and a movable claw
It has a claw opening means for opening, and the fixed claw and the movable claw are
Surround the lower part of the screw with the movable claw closed and
It is placed at a distance slightly larger than the outer diameter of the lower part,
The distributing means has a plate-like member for hooking the head of the screw, and when the screw transferred to the distributing means is held by the holding means, the posture of the screw is corrected, so that the screws are stabilized one by one. Screw can be cut out from the aligned screw group in a fixed position, so that the screw does not bite between the screw feeding path and the distributing means and feeding becomes impossible, and the screw removal operation after distribution is smooth. become.
