Next, the base 68 of the processing unit 10 moves horizontally along the guide rail 64 while stopping at each outer peripheral line display position of the scoring process. At this time, the inkjet nozzle 70 of the inkjet apparatus moves in the shaft direction. A display material of a desired color selected at the injection position is injected and displayed in a circular line shape (S5). When all the perimeter lines N are displayed. The base 68 located on the distal end side of the guide rail 64 of the gantry starts to return, and at that time, the plasma device 76 is activated and the discharge plasma P is irradiated from the plasma irradiation nozzle 72 to reach the proximal end side of the guide rail 64. Irradiation of the discharge plasma P is maintained until this is done (S6). Meanwhile, the shaft 2 supported while rotating is treated with an oxidizing active substance containing radicals such as carboxyl groups and carbonyl groups generated by the reaction between the discharge plasma P and the atmosphere to improve hydrophilicity. After the processing in the processing unit 10, the two-position chuck device is raised and moved forward to discharge one shaft to the recovery unit and recover it (S7). Since the inkjet nozzle 70 and the plasma irradiation nozzle 72 are mounted on the common base 68, each process can be executed during each reciprocating operation on the guide rail, and highly efficient processing is performed. In the embodiment, if the shaft is manually set on the rotation support device 3 only at the beginning of the operation of the device and the shaft material is input to the inclined guide portion 12 to the receiving position K side, the two-position chuck For each of the front and rear operations of the apparatus 40, scoring and discharge surface treatment in the processing unit 10 and introduction of a new shaft material, setting of the processing unit 10 on a rotation support device, and collection of the processed shaft to the recovery unit 11 are performed. The discharge can be performed at the same time. When adhering an arrow blade to the shaft collected in the collection case, as shown in FIG. 10 (a), a natural bird prepared on the basis of a line interval or a line set among a plurality of outer peripheral lines is used. The core of the wing is bonded using, for example, an epoxy adhesive. In the embodiment, three blades are bonded so that the tip is directed in the radial direction at a position shifted by 120 degrees from the blade center, and as shown in FIG. Yes. And it is experimentally proved that when the arrow completed through various steps after bonding is actually used, durability can be maintained several times in terms of the number of times of use compared to the arrow manufactured without performing discharge surface treatment. It was done.

  Further, the arrow machining method of the present invention includes a step of rotating a shaft having a predetermined length around an axis, and a rule for displaying a plurality of outer peripheral lines at a required axial interval in the vicinity of an arrow blade mounting position on one end side of the shaft. And a step of linearly moving along the shaft in a state where the ink jet nozzle for writing display and the plasma irradiation nozzle for discharge surface treatment for discharging the surface of the shaft in a non-contact manner are arranged in parallel.

  The arrow processing apparatus, the arrow processing system, and the arrow processing method of the present invention described above are not limited to the configuration of the above-described embodiment, and depart from the essence of the invention described in the claims. As long as it does not, you may change arbitrarily.

  The arrow processing apparatus, the arrow processing system, and the arrow processing method of the present invention can be applied not only to traditional Japanese bow arrows but also to manufacturing and manufacturing arrows such as new types of bows.
