Here, the nail feeding mechanism 4 operates here, the nail N is sent into the guide cylinder 5 through the slot 82, and the nail N falls in the guide cylinder 5 and is received in the nail holding portion 51.

Then, the servo motor 65 is driven to raise and lower the driving head 71 as shown in FIG. 18, and the head of the nail N is pushed down by the driving rod 79 while the play board 13 is being pressed.
Type in. Since the screw is formed on the nail N, the nail N rotates while being driven to rotate the driving rod 79, but the driving rod 79 has a ball 78 at its upper end.
The rotation is not transmitted to the plate 75 because it is supported by the plate 75. The raising / lowering operation of the driving head 71 by the servo motor 65 will be described. As shown in FIG. 18, the driving head 71 first descends from the standby level to the driving start level.

Next, while repeating a reciprocating operation (step feed) of a small distance in the vertical direction, the step is lowered to the driving completion level. When the player reaches the end level and finishes the driving, he rises to the standby level and stands by. In this way, the head of the nail N is pressed and driven while the feed amount of the driving rod 79 is controlled by the servo motor 65. Therefore, by setting the optimum feed amount based on the resistance when the nail N is driven into the play board 13, the nail N can be driven in a short time with almost no impact sound. The rotation control of the servo motor 65 is performed by a controller (not shown).

Next, the case of using the punching device 7 will be described. Since this is a prototype, a small number of game boards 1
In the case of making No. 3, nails can be driven without making a special jig for punching. Specifically, after the nail driving position data for driving the XY table 9 is input, the punch supported by the movable block 85 is lowered by lowering the air cylinder 76 while the driving head 71 is on standby. 86 is lowered. In this state, the tip of the punch 86 is located below the lower end of the driving rod 79.

Next, the nail driving position data is offset by the amount of deviation from the axial center of the driving rod 79 to the tip of the punch 86, and the XY table 9 is moved.
When the punch 86 is located above the nail driving position, the servo motor 65 is rotationally driven to drive the driving head 7
Lower 1 The amount of descent at this time is a little lower after the punch 86 abuts the play board 13
The punch mark should be stamped on the surface of the. After the punch mark is stamped, the servo motor 65 is reversed to raise the punch 86.

Next, the play board 13 is moved to the next nail driving position, and the next punch mark is stamped in the same manner.
In the case of this punching device 7, since the position data input for nail driving can be shared and used, the operation is easy. Further, it is possible to carry out nail driving continuously on the same game board 13 after punch marks have been stamped, and it is possible to efficiently carry out trial production of a small lot.
