And a stopper 7 that stops the pachinko sphere 1 at the laser irradiation position S for a certain period of time, and a discharge rail 8 that discharges the pachinko sphere after marking from the laser irradiation position S. Here, the marking such as the logo mark 2 on the pachinko ball 1 is performed while the pachinko ball 1 is stopped at the laser irradiation position S by the stopper 7.

  As the laser irradiation device 5, in the present embodiment, the above-described complete air cooling YAG laser marker of Keyence Corporation is used. In FIGS. 2 to 5, a plurality of arrows extending from the laser irradiation device 5 represent the laser beam R. ing. Further, a range irradiated with the laser beam R is set as a laser irradiation position S (see FIG. 3). The laser irradiation device 5 can irradiate a plurality of pachinko spheres 1 at a laser irradiation position S with a plurality of laser beams R at one time, or the laser beam R itself can move only one beam and the laser beam can be moved sequentially. The thing which irradiates the several pachinko ball 1 in the irradiation position S may be used.

  In this embodiment, the rail portion 6 is composed of eight rows of rails connected at one end to the pachinko ball supply body 4, and seven pachinko balls 1 are transferred between the rails ( (See FIG. 4). Further, as shown in FIGS. 2 and 3, the rail portion 6 is inclined downward to the right in the front view, and the pachinko ball 1 supplied from the pachinko ball supply body 4 is placed on the rail along this inclination. Is automatically rolled down. Further, the rail portion 6 in the range (laser irradiation position S) irradiated with the laser beam R from the laser irradiation device 5 is set as an elevating rail 6a that can be moved up and down, and the elevating rail 6a is operated to the raised position as will be described later. The plurality of pachinko balls 1 after marking at the laser irradiation position S are discharged from the discharge rail 8 at a time. As shown in FIG. 4, the elevating rail 6a can be moved up and down by vertically moving a shaft portion provided at the bottom thereof using, for example, a cylinder.

  As shown in FIG. 5, the rail portion 6 is further provided with a shutter 9 made up of a plurality of rod-like members that can be moved up and down between the rails. When the shutter 9 is raised, a predetermined number or more of pachinko balls 1 are irradiated with laser. The entry to the position S is prevented (see FIG. 3C). The plurality of rod-like members of the shutter 9 are connected by a connecting body 9a at the lower end portion thereof, and can be moved up and down by moving a shaft portion provided on the bottom surface of the connecting body 9a up and down using, for example, a cylinder.

  As shown in FIGS. 2 and 3, the stopper 7 is installed at the downstream end of the rail portion 6 (elevating rail 6 a) so as to be able to be raised and lowered, and when it is raised, the pachinko ball has rolled along the inclination of the rail portion 6. It is assumed that the pachinko ball 1 on the most downstream side can move to the upper part of the stopper 7 (see FIG. 3C). In addition, the contact part with the pachinko ball 1 of the stopper 7 is formed in a cross-sectional shape as shown in FIG. 2 and FIG. 3, so that the pachinko ball 1 on the upper surface of the stopper 7 as the stopper 7 descends is formed. It is supposed to be easy to move. Here, the stopper 7 may be made of an elastic member such as rubber in order to prevent scratches or dents on the pachinko ball 1 when the pachinko ball 1 contacts.

  The discharge rail 8 is composed of eight rows of rails that are inclined similarly to the rail portion 6, and as shown in FIGS. 2 and 3, the upstream end (the engagement end portion with the stopper 7) is the rail portion 7 (elevating / lowering). A step is provided so as to be higher than the downstream end of the rail 6a). This step prevents the pachinko ball 1 from being discharged from the discharge rail 8 even when the stopper 7 is in the lowered state (see FIG. 3C).

  Next, the flow of the marking process by the marking device 3 will be described.

That is, when the stopper 7 is lowered, the pachinko ball 1 that has been in contact with the side surface of the stopper 7 rotates (half rotation) in such a manner as to ride on the upper surface of the stopper 7, so that the other pachinko balls 1 also rotate in the same manner. It will be. Here, since the discharge rail 8 is provided with a step at a position higher than the downstream end of the rail portion 6 (elevating rail 6a) as described above, the pachinko ball 1 moved to the upper surface of the stopper 7 Is not discharged from the discharge rail 8. In this state, as shown in FIG. 3C, by irradiating the laser beam R for the second time from the laser irradiation device 5, the user name (branch name is set on the surface of the pachinko ball opposite to the primary marking by 180 °. The logo mark 2 specifying (including) can be engraved (secondary marking). The place where the secondary marking is performed is determined by the width 7 a of the stopper 7. In this embodiment, since the width 7a of the stopper 7 is set to the half circumference of the pachinko ball 1, the pachinko ball 1 is rotated halfway by the lowering of the stopper 7, so that the secondary marking is formed on the surface opposite to the primary marking by 180 °. Applied. Therefore, the marking portion of the secondary marking can be freely changed by appropriately changing the width 7a of the stopper 7.

  After the secondary marking, as shown in FIG. 3 (d), by raising the lifting rail 6a and the stopper 7 by the level difference of the discharge rail 8, the pachinko ball 1 after marking is sent to the discharge rail 8 and collected. it can. After all the pachinko balls 1 at the laser irradiation position S are discharged, the shutter 9 and the lifting rail 6a at the raised position are lowered to return to the state shown in FIG. The pachinko sphere 1 is newly set at the laser irradiation position S. The marking operation on the pachinko ball 1 and the raising / lowering operation of each member of the lifting rail 6a, the stopper 7, and the shutter 9 are performed by the controller 10.

  In the marking device 3 described above, the pachinko sphere 1 after marking from the marking of the logo mark 2 that automatically identifies the user name on the pachinko sphere surface in a series of flows simply by supplying the pachinko sphere 1 to the pachinko sphere supplier 4. Up to 1 recovery can be performed. In addition, since a plurality of pachinko balls 1 at the laser irradiation position S can be engraved at a time, work efficiency is dramatically improved. Further, in the marking device 3, the both sides of the pachinko ball 1 can be engraved in a series of flows. In the case of markings on both sides, it is easier to visually check whether the pachinko balls of the company, other companies, or illegal pachinko balls are compared to the case of only one side.
