Field of the Invention The present invention relates to a reclaiming device for pelletized abrasives used for pachinko ball polishing of pachinko balls, and more particularly, to a drop circulation recovery of pelletized abrasives circulating in a pachinko ball lifting / polishing device. The present invention relates to an abrasive reclaiming device for reclaiming in the process of.

送・研磨装置に循環させるようにしている。[Technical Background] Generally, when polishing used pachinko balls in a pachinko hall, the used out balls discharged from the pachinko machine are collected at a predetermined position below the island table and mixed with pelletized abrasives. By polishing the pachinko balls in the process of conveying them upward with a pachinko ball lifting / polishing device that uses a rotating spiral, and collecting the used abrasive material at the lower entrance of the lifting / polishing device, It is circulated to the pachinko ball lifting and polishing equipment.

応用した研磨材磨き装置を設置している。By the way, an abrasive made of pellets of synthetic resin or the like has its surface soiled by use, and it is necessary to polish and regenerate it as necessary. For this reason, conventionally, an abrasive material polishing device applying the principle of a rice polishing machine is installed near the lower mixing portion of the pachinko ball lifting / polishing device.

現象がおこり、粉々になってしまうという問題があっ
た。However, the conventional polishing apparatus for polishing an abrasive material has the following drawbacks because it has a structure in which the abrasive material is pushed out by a screw laterally arranged in the casing. First, the method of pushing out while polishing with a horizontal screw has a structure in which the abrasive fed from one side of the casing is fed by the screw while it is fed from the upward outlet of the other side, so the amount of abrasive fed is reduced. When it comes, the pushing force tends to be insufficient, and the abrasive tends to stay in the casing. As a result, the phenomenon of excessive polishing of the staying abrasive causes a problem of shattering.

果が得にくい。Secondly, since the conventional device cannot separate the abrasive dust in the casing during the polishing operation of the abrasive, a separate device for separating the abrasive dust from the abrasive discharged from the abrasive polisher is required. become. Moreover, since the polishing debris easily adheres to the surface of the abrasive again during the mixing process, it is not easy to separate the polishing debris from the abrasive sent out from the screw, and even if a suction blower is used, a sufficient effect is obtained. Is difficult to obtain.

There was also a problem that it was difficult to secure.

It rotates along the inner peripheral surface, and in the process, it is polished by the friction of the abrasives while being rubbed by repeated compression-opening between the inner peripheral surface of the polishing tank and the outer surface of the stirring body. Furthermore, the agitation member rotates in the inner circumferential direction of the polishing tank, and air is sucked from the polishing dust suction holes to collect the polishing material near the suction holes in the polishing tank.
When the density increases, the next peak of the agitator rotates to agitate the abrasive while compressing it, thereby promoting friction between the abrasives. Therefore, the strongest polishing action is performed in the vicinity of the suction hole for removing the polishing debris, and the polishing debris separated from the surface of the abrasive is immediately sucked to the outside of the polishing tank through the dust suction hole.

材の密度が高くなるため、研磨効率がさらに良くなる。The vertical ridges and valleys formed on the outer peripheral side surface of the agitator are inclined with respect to the rotation axis of the agitator so that the lower ends of the ridges and valleys rotate before the upper end. In this case, the force to return the abrasive to the upper side against the gravity drop of the abrasive acts, so that the staying time in the polishing tank is adjusted for a long time and the abrasive is sucked near the dust removal suction hole. Since the material has a higher density, the polishing efficiency is further improved.

The pellet-shaped abrasive material 7 falling from the upper part of the pachinko ball lifting / polishing device is the abrasive material inlet 17 of the casing 10.
It is thrown into the upper opening of the polishing tank 11 through the above, and tries to flow to the polishing material discharge port 18 at the lower center of the casing 10 through the inside of the polishing tank 11 by its own weight. At this time, the polygonal polishing tank 1
In FIG. 1, since the stirring body 12 in which the vertical peaks 22 and the troughs 23 are alternately formed on the outer surface is rotated by the vertical rotation drive shaft 21, the polishing material 7 in the polishing tank 11 is stirred. The polishing tank 11 is formed by the ridges 22 and valleys 23 on the outer surface of the body 12.
While rotating along the inner surface and polishing by the stirring action by repeated compression-opening between the uneven inner peripheral surface of the polishing tank 11 and the uneven peripheral side surface of the stirring body 12, the polishing dust suction holes 20 of the polishing tank 11
Sent to the surface of.

Since the abrasive 7 rotates in the polishing tank 11 while being pushed back upward by the inclined V-shaped groove, the time for receiving the stirring action is relatively long, and the abrasive 7 is evenly sent to the vicinity of the polishing dust suction hole 20. become.

る。On the other hand, since the air suction device 15 is connected to the suction hole 19 of the casing 10 and the suction hole 19 of the casing 10 communicates with the suction hole 20 of the polishing tank 11,
When air is sucked from the suction hole 19 of the casing 10, the abrasive 7 in the polishing tank 11 is sucked near the suction hole 20.

And the air is sucked from the suction hole 20, the polishing tank 11 is rotated.
The abrasive 7 is attracted to the vicinity of the suction holes 20 inside, and the density is increased. In this way, when the density of the abrasive 7 is increased, the next crest 22 of the agitator 12 rotates, so that the abrasives 7 receive strong friction and the surface is efficiently polished. At the same time, the polishing dust generated by the friction is immediately sucked to the outside from the suction hole 20. For this reason, the polishing scraps 7 b separated from the polishing material 7 are regenerated by the recycled polishing material 77.
It is efficiently eliminated without being mixed with a again.

過剰による残留研磨材の粉砕が合理的に解消される。As described above, according to the present invention, since the abrasive is polished in the process of falling by its own weight, the abrasive does not remain in the polishing tank even if the amount of the abrasive decreases. Therefore, the crushing of the residual abrasive due to overpolishing, which has been a problem in the past, is rationally eliminated.

の汚れを落すので研磨材にやさしい磨きがかけられる。
従って、不要な汚れだけが取り外かれるので研磨材の寿
命が著しく改善される。By rotating the polishing body and sucking air from the polishing dust suction holes, the polishing material is collected near the suction holes in the polishing tank and the density is increased, so that the peaks of the polishing body are compressed.
Promotes friction between abrasive particles. That is, according to the present invention, the surface of the abrasive is not ground with the blade edge of the abrasive as in the prior art, but the surface of the abrasive is mainly cleaned by the friction between the abrasives, so that the abrasive can be gently polished.
Therefore, only the unnecessary dirt is removed, and the life of the abrasive is significantly improved.
【００３０】また、吸引孔付近に集めた高密度の研磨材
を圧縮しながら摩擦するので研磨屑は直ちに吸引孔から
排出される。このため、研磨材と研磨屑の混合による再
汚染がなくなり、研磨効果が飛躍的に向上する。Further, since the high-density abrasive collected in the vicinity of the suction holes is rubbed while being compressed, polishing debris is immediately discharged from the suction holes. Therefore, recontamination due to the mixing of the abrasive and the polishing waste is eliminated, and the polishing effect is dramatically improved.
【００３１】さらに、本発明は研磨槽を縦長に配置する
ので、パチンコ球揚送・研磨装置における研磨材回収路
に沿って設置することが可能になり、回収スペースを有
効利用できる利点がある。Further, according to the present invention, since the polishing tank is arranged vertically, it is possible to install the polishing tank along the polishing material recovery path in the pachinko ball lifting / polishing device, and there is an advantage that the recovery space can be effectively used.
