Description

Detailed Description of the Invention <Industrial Application Field> The present invention polishes pachinko balls by rotating a brush while supplying a small amount of cleaning liquid inside a polishing chamber, and also dries the polished pachinko balls in a drying chamber. This invention relates to a polishing device for pachinko balls.

<Prior Art> A device for polishing pachinko balls by rotating a brush is known, for example, from Japanese Utility Model Application Publication No. 56-3638.
Further, Japanese Utility Model Application Publication No. 56-47789 proposes an apparatus in which a steel ball is treated with a liquid such as a chemical solution and then moved while wiping and polishing the surface of the steel ball with a porous material such as a sponge.

<Problems to be Solved by the Invention> However, when polishing devices using conventional brushes polish pachinko balls that are relatively clean, they sometimes end up becoming dirty. When we investigated the cause of this, we found that fine dust generated by the wear and tear of the brush remained attached to the surface of the brush bristles and the inner surface of the polishing tube, and that this dust contaminated the surface of the pachinko ball. did. It has also been found that the static electricity generated when the surface of a pachinko ball is rubbed with a brush causes the dust to be attracted to the surface of the pachinko ball, increasing dirt.

Therefore, as a means to reduce the amount of dirt on the brush itself, it is possible to increase the number of bristles installed in the brush or to frequently replace the brush with a new one.

However, it is difficult to significantly increase the number of bristles on the brush due to the structure of the brush and the installation spacer, and it is troublesome to frequently replace the brush itself, neither of which is a rational solution.

On the other hand, when a steel ball is treated with a chemical solution and then wiped and polished with a porous body, the processing and wiping and polishing are inefficient, and the porous body absorbs the chemical solution and becomes saturated in a short period of time. Therefore, it was not practical.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and includes a polishing chamber in which a brush is rotatably inserted into an almost sealed polishing chamber having a ball supply port and a ball discharge port. A cleaning liquid supply device for supplying cleaning liquid in small amounts is connected to the polishing chamber, and a drying chamber is connected to the polishing chamber, and a brush is rotatably inserted into the drying chamber, and a blower is connected to the polishing chamber. , Pachinko balls are polished by rotating a brush while adding a cleaning liquid in the polishing chamber, and then dried by rotating the brush and air in the drying chamber.

<Function> The cleaning liquid supplied from the cleaning liquid supply device polishes the pachinko ball in a wet state in the polishing room, suppressing the generation of static electricity and washing away dirt and dust, and the rotation of the brush and the wind polish the pachinko ball in a wet state in the drying room. Dry the bulbs.

<Examples> The present invention will be described below based on examples shown in the drawings.

The polishing apparatus 1 shown in FIG. 1 has an upper opening of a horizontally long cylindrical polishing tube 2 which is closed by a first lid member 3 and the other opening by a second lid member 4.
A polishing chamber 5 is configured in a substantially sealed manner, a polishing brush 6 is inserted into the interior of the polishing chamber 5, and one end of the shaft 7 of the polishing brush 6 is connected to the first bearing 8 of the first lid member 3. The other end is rotatably supported by the second bearing 9 of the second lid member 4, and a motor 11 is connected to the shaft end protruding from the first lid member 3 via a joint 10.
A drive source such as the following is connected.

The polishing tube 2 is a tube material with a circular cross section, and has a ball supply port 12 on one side of the lower surface, and a long ball holding member 13 is installed in the middle of the height of the inner surface in the length direction of the polishing tube 2. It is located along the The polishing tube 2 is installed so that one end having the ball supply port 12 is slightly higher than the other end.

The polishing brush 6 has countless elastic bristles 14 radially implanted on the circumferential surface of a long shaft 7, and when inserted into the polishing tube 2, the bristles connect with the inner surface of the polishing tube 2. The length of the bristles 14 is set so that the interval between the two is shorter than the diameter of the pachinko ball.

Therefore, when the polishing brush 6 is driven by the motor 11 and rotated in the direction of the arrow in FIG. It is held under the holding member 13, and in this state, the dirty surface of the pachinko ball can be rubbed and polished. The pachinko balls A move along the ball holding member 13 from the ball supply port 12 side to the second lid member 4 side, and are continuously polished during this movement. And the second lid member 4
When the pachinko ball moves to the second position, the polished pachinko ball
The ball is discharged from a ball discharge port 15 provided in the lid member 4.

When the surface of a dirty pachinko ball A is polished with a brush, the dirt adhering to the surface of the pachinko ball is removed, and the bristles 14 of the polishing brush 6 are worn out, and these dirt and abrasion particles are removed from the bristles 14 of the polishing brush 6. or the inner surface of the polishing chamber 5.

FIG. 5 shows the configuration of an embodiment in which the polishing device 1 is incorporated into the so-called island circulation of a row of pachinko machines. Dirty pachinko balls discharged from each pachinko machine 40 are collected by a ball collecting gutter 41 into a ball transport machine. It is collected at the entrance 43 of 42. Then, when the flexible screw 44 of the ball lifting machine 42 is rotated, the pachinko balls that have flowed into the lifting pipe 45 from the inlet 43 rise inside the lifting pipe 45, are discharged from the outlet 46 at the upper end, and are polished. into the device 1. This polishing device 1
Although the configuration is similar to that of the above-described embodiment, it is preferable that the tank 18 is disposed below the row of pachinko machines, and that the cleaning liquid in the tank 18 is pumped and supplied by the pump 47.

The clean pachinko balls polished by the polishing device 1 are discharged in a dry state, flow into a ball supply tank 48 disposed above the row of pachinko machines, and are stored therein. The clean pachinko balls stored in this ball supply tank 48 are supplied to each pachinko machine 40 as needed via a ball supply gutter 49.

In this way, when the polishing device 1 according to the present invention is incorporated into a so-called island circulation element, unlike the conventional polishing device, the dust etc. that have come off from the pachinko machine will not adhere to the pachinko balls again and contaminate the pachinko balls. Therefore, even if the pachinko balls discharged from the pachinko machines 40 are dirty or have relatively little dirt, clean and dry pachinko balls can always be supplied to each pachinko machine 40.

<Effects of the Invention> As explained above, according to the present invention, wet pachinko balls are polished with a brush while a small amount of cleaning liquid is supplied into the polishing chamber, and then dried in a drying chamber by wind and rotation of the brush. Therefore, it is easy to remove dirt from pachinko balls, and the generation of static electricity can be suppressed. Therefore, not only can pachinko balls be polished extremely efficiently, but also dirt does not adhere to the pachinko balls again.

Further, since the dirt in the polishing chamber is reliably discharged to the outside using the cleaning liquid, the polishing brush can always be maintained in a clean state. Therefore, it is possible to eliminate the conventional inconvenience of pachinko balls becoming contaminated due to dirt in the polishing chamber, and it is also possible to reduce brush wear and improve durability.
Maintenance and inspection can be significantly simplified.

Since the pachinko balls that have been polished and cleaned are dried in a drying room, pachinko balls that are free from moisture can be used for games, making it possible to play pachinko games that are clean and highly entertaining.
