薬剤を含浸後乾燥までに長時間を要する場合には、薬剤を含んだ液体が腐敗して悪臭を発する原因となる。また、人の手指が接触することから考えても、薬剤には防腐・抗菌剤を混合するのが望ましい。塩化ベンザルコニウムなどのカチオン界面活性剤は水への溶解性が良好であり、使用しやすいものである。
また、大気中には微細な塵や埃が浮遊しており、遊技媒体が帯電するとこれらが吸着して汚染されるので、薬剤には帯電防止剤を混合するのが望ましい。帯電防止剤として第４級アンモニウム塩類等のカチオン界面活性剤が効果的である。 以上のような薬剤を浸漬、塗布、噴霧などにより研磨シート４に含浸させた後に、自然乾燥もしくは温風や乾燥機などを用いて乾燥するが、若干の湿気の残留は許容されるものである。
【００１７】
研磨シート４はメダルを研磨中は間欠送りされつつ送水管５１から水分が添加される。水の添加は滴下方式を採用することができる。即ち、送水管５１の途中に横に捩じって開閉する栓（図示していない）を設け、この栓の開度を調整することにより滴下量を調整することができる。また、電磁弁を用いてコントローラ６によりこの電磁弁を間欠的に開閉することによっても、添加水量を調整して研磨シート４を一定の湿潤状態に湿らせることができる。水は、上側の研磨シート４に滴下することにより下側の研磨シート４に浸透し、上下両研磨シート４を湿潤状態に湿らせることができる。
以上のような薬剤が乾燥された研磨シート４を用いて、この研磨シート４に水分を添加しながらメダルを通過させることによって、綺麗にメダルを研磨することができる。なお、研磨シート４はパチンコ機の揚送装置の内部に設けて、水分を添加しつつパチンコ球を研磨することができるのはもちろんのことである。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. 2 and 3 are diagrams showing a game medium lifting device for lifting a medal, which is a game medium, to the upper part of the gaming machine installation island, and the polishing device 2 is installed at the lower part of the lifting device 1. Yes. In the polishing apparatus 2, the medal transport belt 3 is stretched around four pulleys 31 driven by the motor M 1, and a pair of polishing sheets 4 are stretched up and down across the medal transport belt 3. Has been. A water tank 5 is installed above the polishing apparatus 2, and water is supplied to the polishing sheet 4 through a water supply pipe 51.
[0007]
As shown in detail in FIG. 4, the medal transport belt 3 has a pair of left and right endless belts 32, and a thin plate 33 for holding a medal that is substantially U-shaped and thinner than the thickness of the medal is arranged in a ladder step at regular intervals. A medal polishing receiving portion 34 opened between the front and rear thin plates 33 is formed. The receiving portion 34 has a size that allows a single medal to enter in the traveling direction, but is formed in a width that allows a plurality of medals to enter in the horizontal direction. It can be held and transported in a single row. The polished medal is discharged from the discharge path 35 to the lifting device 1.
[0008]
The details of the polishing apparatus 2 are shown in FIG. 1. As described above, the polishing apparatus 2 includes a pair of polishing units sandwiching a part of the upper circumferential portion of the medal transport belt 3, that is, a transport section for game media from above and below. A sheet 4 is stretched. The polishing sheet 4 is inserted in a roll shape into a discharge shaft 41, and its tip is locked to a take-up shaft 42, and is tensioned and stretched by guide rollers 43 and 44. In addition, the winding shaft 42 has a split groove, and the tip of the polishing sheet 4 can be inserted into the split groove and locked. A water supply pipe 51 for replenishing the polishing sheet 4 with water is disposed at the entrance of the polishing sheet 4 near the guide roller 43.
[0009]
Further, the polishing apparatus 2 includes a motor 45 that drives the winding shaft 42 and a controller 6 that drives the motor 45 intermittently, and further includes a pitch plate 71 for measuring the feed amount of the polishing sheet 4. A pitch roller 7 and a photosensor 8 that detects the rotational speed of the pitch roller 7 and transmits the rotational speed to the controller 6 are provided.
[0010]
The medals are polished by passing between the polishing sheets 4 stretched up and down in the middle of being conveyed by the medal conveying belt 3, but the polishing sheet 4 is contaminated by the polishing of the medals, so that the polishing unit moves intermittently. Is done. That is, when the winding shaft 42 is rotated by driving the motor 45, the polishing sheet 4 is wound up and the pitch roller 7 disposed in contact with the polishing sheet 4 is rotated. The photo sensor 8 counts the number of sheets passing through the pitch plate 71 of the pitch roller 7 and stops the motor 45 when a predetermined number of sheets passes. After a predetermined time has elapsed after the stop, the controller 6 drives the motor 45 again. Thereafter, this operation is repeated in the same manner, and the polishing sheet 4 can be shifted by 25 mm, for example, every 15 minutes. The time and the amount of winding are appropriately adjusted according to the congestion situation of the game hall.
[0011]
The abrasive sheet 4 is made of a cloth, paper or the like and is impregnated with a chemical. It is desirable that the chemical contains a surfactant as an essential component, and one or two or more of a lubricant, a rust inhibitor, an antiseptic / antibacterial agent, and an antistatic agent are blended therein. The surfactant is an essential component because it has excellent detergency for sebum dirt and is a particularly effective component for cleaning game media that are frequently touched. Further, it is necessary that the surfactant does not cause whitening or dusting when dried. Many anionic surfactants and cationic surfactants are dried in solid form, and many nonionic surfactants such as polyoxyethylene alkylphenyl ether are liquid. The surfactant is also essential for emulsifying and dispersing the lubricant.
[0012]
As the lubricant, silicone oil, wax, mineral oil, vegetable oil, or the like can be used. Particularly, amino-modified silicone used also as a fabric softener has good adsorptivity to fibers, is excellent in terms of durability of fibers, and is suitable because it can provide gloss with a lubricating effect in a small amount. It is.
Further, since many medals are made of brass and easily change color, it is desirable to prevent rust against copper. Triazoles such as benzotriazole and tolyltriazole are effective because of their good adsorptivity to the metal surface.
Tables 1 to 3 illustrate the components of the drug.

[Table 3]

[0016]
When it takes a long time to dry after impregnating the drug, the liquid containing the drug rots and causes a bad odor. In view of contact with human fingers, it is desirable to mix antiseptic and antibacterial agents with the drug. Cationic surfactants such as benzalkonium chloride have good solubility in water and are easy to use.
In addition, fine dust or dust is floating in the atmosphere, and when the game medium is charged, these are adsorbed and contaminated, so it is desirable to mix an antistatic agent with the drug. Cationic surfactants such as quaternary ammonium salts are effective as antistatic agents. After impregnating the polishing sheet 4 with the above chemicals by dipping, coating, spraying, etc., it is naturally dried or dried using warm air, a dryer, etc., but some moisture remains acceptable. .
[0017]
The polishing sheet 4 is intermittently fed during polishing of medals, and moisture is added from the water supply pipe 51. The addition of water can employ a dropping method. That is, the amount of dripping can be adjusted by providing a plug (not shown) that twists and opens in the middle of the water supply pipe 51 and adjusts the opening of the plug. Further, the polishing sheet 4 can be moistened to a constant wet state by adjusting the amount of added water by intermittently opening and closing the electromagnetic valve by the controller 6 using the electromagnetic valve. Water can permeate into the lower polishing sheet 4 by dripping onto the upper polishing sheet 4 and wet both the upper and lower polishing sheets 4 in a wet state.
By using the polishing sheet 4 from which the chemicals as described above are dried, the medal can be beautifully polished by passing the medal while adding moisture to the polishing sheet 4. Needless to say, the polishing sheet 4 can be provided inside the lifting device of the pachinko machine to polish the pachinko balls while adding moisture.
[0018]
【The invention's effect】
As described above, polishing sheet Ken, previously impregnated drug leave dry, since to use by adding water when polishing the game medium, lowering the polishing ability washings dried There is nothing to do. In addition, salt attached by a human finger can be effectively removed by moisture, and the game medium is not rusted or discolored. Since the chemical is a surfactant and one or more of lubricants, rust inhibitors, antiseptic / antibacterial agents, and antistatic agents are blended, it gives a lot of performance such as lubricity to the game media. can do. In addition, the polishing apparatus of the present invention has the above-described polishing sheet stretched on the game medium transport unit and a water addition device for adding moisture to the polishing sheet is provided, so that the polishing ability is always constant. It is possible to maintain and efficiently polish the game medium.
