It is known from the 19791 publication. However, in this conventional ball-grinding carrier, the pachinko balls are fed only by the friction of the belt, so that the feeding force is weak and it is impossible to obtain sufficient polishing force and pachinko ball feeding force.

[0003]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a pachinko ball polishing apparatus which solves these conventional problems and can obtain a strong polishing force and a pachinko ball feeding force. It is in.

[0004]

[Means for Solving the Problems] The constitution of the present invention which has solved the above problems is as follows: 1) A pachinko ball transfer path in the middle of a pachinko ball transfer path in which a plurality of pachinko ball transfer paths for sending one pachinko ball at a time are arranged in parallel. A feed roller having a rotary shaft in a direction orthogonal to the feed direction is provided, and a plurality of rows of elastic annular grooves are provided on the outer periphery of the feed roller at intervals such that adjacent pachinko balls in the axial direction do not contact each other. A ball receiving part is arranged on the outer periphery of the roller, a plurality of rows of ball receiving grooves are provided on the inner surface of the ball receiving part so as to face the annular groove, and a polishing cloth is attached to the surface of the ball receiving groove. Pachinko ball polishing device characterized by accommodating a pachinko ball between the groove and the polishing cloth and forcibly feeding it while rubbing the pachinko ball against the polishing cloth to polish 2) It can be moved along the inner surface of the receiving groove to change the polishing surface of the polishing cloth. The pachinko ball polishing apparatus according to the above 1) that can be used 3) The delivery side of the ball receiving part is extended vertically, and a vertical wall plate urged by a spring toward the vertical extension is vertically extended. The pachinko ball polishing device according to the above 2) which is placed opposite to the section 4) From a plurality of pachinko ball passage grooves arranged so that the pachinko ball transport path from the end of the ball receiving portion does not contact the pachinko ball in another row. The vertical groove plate and the vertical wall plate facing the vertical groove plate, and the pachinko balls sent from the end of the ball receiving portion are passed between the vertical groove plate and the holding vertical wall plate. ) Or 2) Pachinko ball polishing device 5) Pachinko ball polishing device according to 1) or 2), wherein the pachinko ball transport path from the end of the ball receiving part is connected to the pachinko ball storage chamber 6) Vertical groove plate A crack is formed in the middle of the ascending path formed by the vertical wall plate. Pachinko ball polishing device according to 4) above, which is provided with a coin ball auxiliary feeding mechanism 7) Pachinko ball polishing device according to 3), which is provided with a pachinko ball auxiliary supplementary feeding mechanism in the middle of the vertical extension of the ball receiving part 8) Feed The pachinko ball polishing apparatus according to any one of 1) to 7) above, wherein a cleaning brush is provided on the outer periphery of the roller.

[0005]

In this invention, the pachinko balls are sent from the pachinko ball conveying path one by one in a plurality of rows (without overlapping in a plurality of stages),
The pachinko balls are sequentially sent to the space between the annular groove on the outer periphery of the feed roller and the ball receiving groove of the ball receiving part, and the elasticity of the annular groove of the feed roller presses the pachinko balls strongly against the polishing cloth of the ball receiving groove. While being rubbed and polished, it rotates and is forcibly sent along the ball receiving groove. Since the pachinko balls in the ball receiving groove are strongly pressed against the polishing cloth by the elasticity of the feed roller rotated by the drive device, a strong polishing force can be obtained. Further, the pachinko balls can be strongly propelled by the elastic annular groove, and a large number of pachinko balls can be raised in contact with each other.

If the polishing cloth on the inner surface of the ball receiving portion is made movable, the polishing surface can be changed, and the surface with less dirt can be used as the polishing surface without replacement. If the pachinko conveying path from the end of the ball receiving part is composed of a vertical groove plate and a pressing vertical wall plate, the pachinko ball between the vertical groove plate and the pressing vertical wall plate will be generated by the strong forced feeding force of the feed roller. It can be sent to the passage and the upper and lower pachinko balls can be raised to a high level in contact with each other. At this time, since the pachinko balls do not come into contact with another groove row, it is possible to surely raise the pachinko balls without interfering with each other and causing the pachinko ball row to collapse.
If the pachinko ball conveying path from the end of the ball receiving portion is connected to the pachinko ball storage chamber, the pachinko balls can be continuously polished and stored in the storage chamber. Furthermore, if the forced feed force of the feed roller is insufficient, another auxiliary feed mechanism can be provided more strongly by providing it in the middle of the ascending path between the vertical groove plate and the vertical wall plate or in the middle of the vertical extension of the ball receiving part. You can raise the pachinko ball.
