2. Description of the Related Art In a conventional game arcade using a pachinko machine, a so-called "island" is formed in units of a plurality of pachinko machines and peripheral devices, and pachinko balls used for a game are circulated in this island. It has become. Pachinko balls that have been played include pachinko balls taken into pachinko machines,
It is classified as a pachinko ball as a prize acquired by the player, but all are once returned to the island, the former directly from the pachinko machine, the latter from the prize ball counting machine to the island. Will be returned. The pachinko balls returned to the island are collected by a polishing machine through a collecting gutter, and the polished pachinko balls are supplied to each pachinko machine again. On the island, the pachinko machines are arranged side by side with the front facing outward, and a similar machine is provided back-to-back with space,
A collecting gutter for circulating pachinko balls, a storage tank for pachinko balls, various power supplies, and line facilities are arranged. The gathering gutter is inclined downward from the both ends of the island toward the center, and a grinder is arranged in the center.Thus, all the pachinko balls that have been played through this gathering gutter are gathered in the grinder. Can be. This polishing machine has a type of polishing a pachinko ball by stirring an abrasive and a pachinko ball, and in this type of polishing machine, a separation device for separating the abrasive and the pachinko ball after polishing is provided. After the separation step, only pachinko balls are supplied to the pachinko machine (for example, JP-A-4-44988 and JP-A-8-814). Pachinko balls that have been played are easy for oils and fats to adhere to a player,
Due to the attachment of the fats and oils, an extremely large amount of dust is attached to the pachinko balls. Therefore, the pachinko balls taken into the polishing machine not only remove fats and oils but also remove dust. Therefore, as a conventional dust removing means, for example, as disclosed in JP-A-5-48985, a dust collecting device is connected to a separating device by an abrasive collecting pipe, and a dust collecting filter is attached to a dust suction port. hand,
Dust has been collected through the dust filter.

[0003]

However, since the types of dust adhering to the pachinko balls having been played are not uniform, the specifications of the eyes of the dust collecting filter cannot be determined unconditionally. In other words, in order to collect all types of dust, various types of dust must be collected by arranging a plurality of types of dust collection filters in a plurality of stages. for that reason,
Not only is the structure of the dust collecting device complicated, it is difficult to reduce the weight and labor, but also the maintenance work such as replacement of the dust collecting filter is complicated and the work efficiency is easily reduced. To simplify the configuration, it is conceivable to attach only a dust collection filter for the purpose of removing visible dust.However, in such a case, dust having a smaller diameter than the eyes of the dust collection filter may be used. Pass through,
Diffusion into the air or accumulation in the island may cause failure of equipment such as a pachinko machine. Further, the collection and recovery of fine dust is easy to be diffused by the flow of air and is difficult to handle. Therefore, a reliable and easy dust collection means is desired. An object of the present invention is to reliably collect dust and dirt generated when polishing the collected game media, and to facilitate maintenance of the dust collecting device.

Regardless of the model, the game medium polishing machine is provided with a structure for separating a polished pachinko ball and a non-pachinko ball, that is, a foreign substance such as dust. In the present embodiment to be described later, after the foreign matter is separated from the polished pachinko ball P, the foreign matter is further separated into an abrasive G and dust D, and the dust D is collected by the dust collecting device 6 having the tank 8. The configuration is described. In the game medium polishing machine shown in FIG. 3, a pachinko ball P as a game medium collected from a pachinko machine as a game machine and a granular abrasive G having an outer dimension smaller than a pachinko ball diameter.
The pachinko balls P are lifted up by the lifting device 1 while polishing to grind the pachinko balls P, and the separated pachinko balls P, the abrasive G received from the lifting device 1 and the abrasive G and the dust generated from these are lifted by the separating device 2. D, and the separated abrasive G and dust D are collected in the abrasive collection passage 3 and the dust collection passage 4, respectively. The collected abrasive G is temporarily stored in the abrasive storage tank 5, The collected dust D is collected by the dust collection device 6.

[0007] First, the dust collecting device 6 constituting a feature of the present invention will be described with reference to FIGS.
In the dust collector 6, a tank 8 is accommodated in a frame 7 (FIG. 1), and a liquid 9 is contained in the tank 8. The tank 8 is formed to be vertically separable in the illustrated embodiment. In the tank 8, guidance for guiding the pachinko balls P put into the pachinko machine and the dust D attached to the pachinko balls P discharged from the pachinko machine together with the air A onto the water surface (surface) of the liquid 9. A hose 10 is provided. The guide hose 10 communicates with the dust collection passage 4 for collecting dust D attached to the pachinko balls P on the upper side in FIG. The dust D is sucked into the guide hose 10 in accordance with the rotation of a fan 12 that is rotationally driven by a drive motor 11, that is, a suction unit provided downstream of the dust collection passage 4. The guide hose 10 is positioned by a mounting member 13 attached to the frame 7 such that the open end 10a faces the water surface of the liquid 9 and is located immediately above the water surface. The distance between the open end 10a of the guide hose 10 and the water surface of the liquid 9 is such that the air A containing the dust D discharged from the open end 10a is
And the dust D is caused to collide with the air surface
And close enough to be separated. The tank 8 has a water level sensor 14 for detecting the water level of the liquid 9 therein.

The signal output circuit 15 is connected to display means (replacement instruction display lamp in FIG. 1) 16 for notifying the replacement of the liquid 9. Above the tank 8, a gas bleeding pipe 17 is attached above the surface of the liquid 9. One or a plurality (two in the figure) of water splash prevention plates 18 are attached to the lower opening side in the gas extraction pipe 17. As shown in FIG. 2, a plurality of vent holes 18a are formed in each water splash-out prevention plate 18. It is desirable that the positional relationship of the vent holes 18a in the upper and lower water splash prevention plates 18 be shifted from each other in order to enhance the water splash prevention effect. With such a configuration, the air A containing the dust D is guided to the tank 8 by the guide hose 10 as shown in FIG.
And collides with the surface of the liquid 9 in the tank 8,
Dust D is separated from the air A, and the dust D is adsorbed and collected in the liquid 9, and the air A 1 is discharged from the tank 8 to the outside of the frame 7 via the gas removal pipe 17. Therefore, the air A1 that does not include the dust D is released from the tank 8 to the outside of the frame 7, so that the diffusion of the dust can be suppressed. At this time, the vent pipe 17
Since the water splash prevention plate 18 is disposed at the lower end opening of the, the water splash from the vent pipe 17 to the outside of the tank 8 is prevented. The processing of the collected dust D is performed by the liquid 9
Together with the new liquid in the tank 8, the maintenance of the apparatus 6 is simplified. The liquid 9 is filled up to the water level at the upper end of the water level sensor 14 as shown. Then, the liquid 9 is replaced when it has dropped to the water level set by the water level sensor 14 due to evaporation or the like. When the water level falls below the set value, the water level sensor 14 is activated and the display means 16 is displayed. At that point, the liquid 9 is replaced or replenished. The above-mentioned dust collecting device 6 is installed in the lifting device 1 as shown in FIG. 3, for example. The hoisting device 1 is provided horizontally with an erecting hoisting pipe 19, a hoisting screw 21 rotatably inserted into the hoisting pipe 19 by a hoisting motor 20, and hoisting at the tip.
