き、生産性を向上させることができるようになる。(Operation) According to the present invention, the plate material forming the pachinko machine board surface is conveyed to the multi-axis drilling machine by the intermittent transporting device, and the reference hole and the band mounting hole are perforated by the multi-axis drilling machine. After the completion of drilling, the plate material is transported from the multi-axis drilling machine to the drilling inspection device by the intermittent transport device, and the reference hole insertion member and the band mounting hole insertion pin of the drilling inspection device are inserted and penetrated into the drilling position of the plate material. At this time, the insertion driving device inserts the insertion member into the reference hole while gradually bringing the insertion member closer to the reference hole that has already been punched in the plate material, and the insertion member is inserted into the insertion member according to its cross-sectional shape along with this insertion. When the displacement of the reference hole is gradually corrected according to the progress of the proximity state, when the insertion member is inserted until the proximal end, that is, the fitted state,
The plate material is surely placed at an appropriate position with respect to the perforation inspection device. Subsequently, the pressing drive device presses the holding plate against the plate material with the insertion member inserted in the reference hole.
Since the drive shaft of the pressing drive device and the insertion drive device are coaxial,
Since the forces applied to the plate material by both devices act in the same direction, the pressing force of the holding plate does not work in the direction deviating from the proper position with respect to the plate material, so that the proper position of the plate material is maintained. If the plate material has a predetermined hole, each insertion pin is penetrated into the hole, and at the time of this penetration, it is not only inspected whether the through hole is drilled at a predetermined position, but also the reference that was drilled in the previous step. The wood chips remaining in the holes and the band mounting holes are pushed out to the opening opposite to the insertion side. At this time, since the game board is a wooden plate material, even if a small amount of burrs and chips remain, it has very little effect on the post-process, and the multi-spindle drilling machine does not have to be provided with a relatively high hardness drill hole. Good. After the pin insertion process is completed, the insertion drive device drives the insertion member away from the reference hole while the pressing drive device keeps the pressing plate pressed against the plate material, so that the insertion member and the reference hole are fitted together. While releasing, remove the insertion member from the reference hole. In this step, excessive pressing force is applied to the plate material at the time of fitting, or friction force generated between the plate material and the insertion member due to the inclusion of chips and burrs remaining for some reason, etc. In some cases, the force required for supporting the plate member by its own weight is exceeded, but in this case, the pressing drive device presses the plate member by the holding plate, and the pressing force acts in the direction opposite to the direction in which the insertion member is pulled out from the reference hole.
It is carried out to the next process device by the intermittent transfer device. For this reason, the band mounting hole processing is completely automated, and it is possible to efficiently process a large amount of plate material without manual intervention, eliminating the time loss for loading and unloading and improving productivity. Will be able to.

も発生しない。In addition, since the game board is made of wood, compared to metal materials and synthetic resin materials, it is easier to machine and deburr the pachinko machine board surface. The workability is prevented from deteriorating without any adverse effect. Furthermore, even if chips and burrs remain on the pachinko machine board surface in this process, the remaining chips and burrs do not have any effect in the post-process of the perforation inspection device, and other configurations of the pachinko machine. By being covered with the member, there is no problem in appearance.

装置によって防止できる。Subsequently, the pressing drive device holds the proper position of the plate material by pressing the holding plate against the plate material in a state where the insertion member is inserted in the reference hole, and the reduction in the positioning reliability is suppressed. Further, after the inspection of the through hole by the band mounting hole insertion pin, the insertion drive device drives the insertion member in the direction away from the reference hole while the pressing drive device presses the holding plate against the plate material. The insertion member is pulled out from the reference hole while releasing the fitted state of the insertion member and the reference hole, but even if the frictional force generated between the plate member and the insertion member exceeds the force required for supporting the plate member by its own weight, The insertion drive device can prevent an accident in which the member and the insertion member are removed from the proper position against the purpose.

上する。On the other hand, the perforation inspection device has a simple structure in which only the insertion member and the band attachment hole insertion pin are simultaneously tested while the insertion member is passed through the reference hole and the band attachment hole insertion pin is penetrated through the band attachment hole. Prevents the increase of the equipment cost because residual chips in the through hole, that is, the reference hole and the band mounting hole are pushed out to the opening on the side opposite to the insertion side for processing without separately providing other dedicated means. The workability is improved because the work waiting time is shortened. Therefore, the productivity is greatly improved and the process control is facilitated. By combining with an intermittent transfer device, the time required for loading and unloading can be shortened and work efficiency can be greatly improved.
