Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention particularly relates to a polishing device suitable for polishing medals used in medal game machines and the like.

2. Description of the Related Art Conventionally, an elastic spiral ring body is disposed inside a cylindrical body so as to be rotatable around a vertical axis. The thread wheel mixes the medals and the synthetic resin abrasive and transfers them from the lower end of the cylinder toward the upper end.At the same time, the medals and the abrasive are agitated as the spiral wire rotates, and the medals are mixed. 2. Description of the Related Art A polishing device is known that uses an abrasive material to remove dirt attached to a surface.

Problems to be Solved by the Invention However, in conventional polishing devices, the amount of upward feeding of medals and abrasive material by the spiral wheel body is constant, and therefore it is not possible to polish a large number of medals. Since the abrasive material cannot be stirred sufficiently by the rotation of the spiral ring body, it is difficult to completely remove dirt from the surface of the medal, and the medal inside near the bottom end of the cylinder is subjected to large pressure from above. , there was a risk that the medal would become deformed.

An object of the present invention is to solve the above-mentioned problems by rotating the support stand around a horizontal axis with respect to the machine frame, so that the polishing tank can be moved to the lower part of the separation tank as the support stand rotates. The medals and abrasive material are put into the polishing tank through the sorting cylinder, and the polishing tank rotates with respect to the support base around an axis that intersects with the horizontal axis, separating the medals and the abrasive material. The polishing tank is sufficiently stirred by rotation of the polishing tank, dirt adhering to the surface of the medals is removed with an abrasive material, and a large amount of medals are polished in the polishing tank. This prevents the medal from deforming without applying greater pressure.
The separation tank is tilted so as to be located at the bottom of the polishing tank as the support base rotates, and the medals and abrasive material inside the polishing tank flow down toward the sorting tube, and the medals pass through the sorting tube and into the separation tank. At the same time as being discharged to the outside, the abrasive passes through the through hole of the sorting tube and is stored in the storage section.Only the abrasive is separated from the medals by the sorting tube.After separating the abrasive from the medal, the separation tank is moved to a support stand. It is an object of the present invention to provide a polishing device capable of quickly returning abrasive material in a storage portion to a polishing tank through a through hole of a sorting cylinder simply by positioning the polishing material in the upper part of the polishing tank by rotating the polishing device.

Means for Solving the Problems The polishing apparatus of the present invention includes a support base rotatably disposed on the machine frame around a horizontal axis, and a polishing tank mounted on the support base around an axis intersecting the horizontal axis. A separating tank is provided adjacent to the polishing tank, a sorting cylinder communicating with the polishing tank is arranged inside the separating tank, and a number of through holes are provided in the peripheral wall of the sorting cylinder. The present invention is characterized in that a storage portion is formed between the separation tank and the sorting cylinder.

By rotating the support base disposed on the working machine frame around the horizontal axis, the polishing tank is tilted to be located at the bottom of the separation tank as the support base rotates, and the medals and abrasive material are placed in the polishing tank. After the medals are fed into the polishing tank through a sorting tube installed inside a separation tank installed adjacent to the medallion, the polishing tank is rotated with respect to the support base around an axis that intersects with the horizontal axis. and the abrasive material are mixed and stirred as the polishing tank rotates, and dirt adhering to the surface of the medal is removed by the abrasive material.

In addition, as the support base rotates, the separation tank is tilted so that it is located at the bottom of the polishing tank, and the medals and abrasive material inside the polishing tank flow down toward the sorting tube, and the medals are separated through the sorting tube. At the same time as being discharged to the outside of the tank, the abrasive passes through a number of holes provided in the peripheral wall of the sorting tube and is stored in the storage section formed between the separation tank and the sorting tube, and the sorting tube separates from the medals. , to separate the abrasive material from the medallion.
