  The present invention has been made in order to solve the above-described conventional problems and to provide a pachinko ball polishing apparatus that can be made compact and can polish the entire circumferential surface of a sphere.

  The pachinko ball polishing apparatus of the present invention, which has been made to solve the above problems, includes a rotating rod having a spherical groove for conveying a ball formed on the outer peripheral surface, and a groove for guiding the ball parallel to the rotating rod. The formed polishing guide member, the polishing cloth laid in the groove, and an elastic body that urges the polishing guide member in the direction of the rotating rod and presses the polishing cloth against the sphere in the spiral groove. The ball is polished by rubbing the polishing cloth while the screw is conveyed in the groove portion by the rotation of the rotating rod.

  It should be noted that a gap is formed between the rotating ball and the next ball following the ball captured in the spiral groove at the end of the rotating ball on the sphere side so that the next ball and the rotating rod are not in contact with each other. desirable. In addition, a sphere supply mechanism having a sphere introduction path leading to the groove portion can be disposed at the end portion of the groove portion on the sphere side, and the bottom surface of the sphere side end portion of the groove portion is curved. It is desirable to prevent the step between the ball introduction path exit side and the groove entering side when the polishing guide member is pushed up by the elastic body due to the absence of the sphere.

  In the pachinko sphere polishing apparatus of the present invention, the balls are screw-transferred during polishing, so that the spheres can be rotated forward and laterally and the entire circumferential surface of the spheres can be polished. Further, since the polishing cloth is pressed against the sphere by the urging force of the elastic body, the sphere can be polished with an appropriate pressure. In addition, since a gap was formed between the next ball following the ball taken into the spiral groove at the end of the ball containing the rotating rod and the rotating rod, the next ball was bitten simultaneously with the previous ball. Can be prevented. Moreover, since the sphere supply mechanism is provided at the end of the groove portion on the sphere side, the supply of the sphere to the groove portion can be performed smoothly. Further, since the bottom surface of the end portion of the groove portion on the sphere side is formed in a curved shape, when the polishing guide member is pushed upward due to a ball breakage or the like, between the sphere introduction path exit side and the groove portion entrance side There is no step. Therefore, the leading sphere for which supply has been resumed is not clogged with a step.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1 and 2 are diagrams showing a schematic configuration of a pachinko ball polishing apparatus according to the present invention. In the figure, 1 is a rotating rod arranged horizontally, and 2 is a polishing guide member. The rotating rod 1 is connected to a driving roller 21 for lifting a ball by gears 22, 23, 24, 25, 26, 27 and rotates in synchronization with the driving roller 21. On the outer peripheral surface of the rotating rod 1, a spiral groove 3 for conveying the sphere by screw is formed from the sphere-containing end 1 a to the ball exit-side end 1 b of the rotating rod 1. Is a spiral ridge 10. Further, the polishing guide member 2 is disposed vertically below the rotating rod 1, and this guide member 2 is urged toward the rotating rod 1 by an elastic body 7.

  3 to 5 show the detailed structure of the polishing apparatus. As described above, the spiral rod portion 10 is provided around the rotating rod 1, and the spiral groove 3 is formed between them. The polishing guide member 2 provided vertically below the horizontal rotating rod 1 has a concave groove 4 formed on the surface facing the rotating rod 1, and the groove 4 is a rotating rod. 1 is arranged so as to be parallel to the axial center 1c. A polishing cloth 6 is laid so as to cover the groove 4.

  A sphere supply mechanism 5 is disposed at the sphere-containing end 1 a of the rotating rod 1, and the sphere supply mechanism 5 includes a sphere supply member 12 having a sphere introduction path 11 that communicates with the groove 4, and It consists of an inclined rod 13 that feeds a ball into the ball introduction path 11. The sphere is sent to the sphere introduction path 11 down the inclined rod 13. Further, the ball introduction path 11 is inclined slightly lower forward.

  Then, the spheres are formed in a line by forming the groove portions 4 and the sphere introduction paths 11 so as to communicate with each other substantially in a line. When the rotating rod 1 is rotated, the spiral crest 10 of the sphere-side end 1a cuts between the sphere rows, so that the spheres are taken into the spiral groove 3 one by one and the spheres are grooved 4 The inside can be screwed.

  When the sphere is taken into the sphere-containing end 1a from the lateral direction of the rotating rod 1, the next sphere following the sphere taken into the spiral groove 3 and the rotating rod 1, as shown in FIG. It is desirable to form a gap between them. By forming the gap, the next sphere and the rotating rod 1 can be brought into non-contact, so that the next sphere can be prevented from being bitten simultaneously with the previous sphere.

  FIG. 3 is a view showing a state in which no sphere is present in the spiral groove 3, and the polishing guide member 2 is elastically ejected upward by the urging force of the elastic body 7, and the bottom surface of the spiral groove 3 The distance from the bottom surface of the groove 4 facing this is narrower than the diameter of the sphere. Therefore, when the sphere is taken in by the spiral groove 3, the polishing cloth 6 can be pressed against the sphere by holding the sphere between the groove 4.

  Further, since the bottom surface of the grooved side end portion of the groove portion 4 is the curved bottom surface 4a, when the polishing guide member 2 is ejected upward due to the absence of the sphere, the outlet of the sphere introduction path 11 and the groove It is prevented that a step is formed between the end portion of the strip 4 and the ball side. Therefore, when the taking-in of the sphere is resumed, the sphere moves along the curved strip bottom surface 4a without clogging the step, and the polishing guide member 2 is gradually pushed down to a steady state of polishing as shown in FIG. Can be migrated.

  Since the ball conveyed by the screw rotates in two intersecting directions, the axial direction of the rotating rod 1 and the direction along the spiral groove 3, the entire circumferential surface of the ball can be polished. The polishing cloth 6 can be replaced with a new one as appropriate, or the endless or endless shape can be formed and the spheres can be polished at the non-contaminated portion while being appropriately wound according to the degree of dirt. it can. The polished ball is discharged from the ball exit side end 1b of the rotating rod 1 and sent to the ball passage 28 of the ball lifting device 20, and is transported to the upper part of the pachinko machine installation island by the rotation of the driving roller 21. .

  As described above, the pachinko ball polishing apparatus according to the present invention is configured to polish the ball while conveying the screw, so that the entire circumferential surface of the ball can be polished by rotating the ball in two intersecting directions. There is a big effect. Further, since the polishing apparatus can be provided independently of the lifting apparatus, there is an advantage that it can be made compact.
