Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game medium cleaner for cleaning game media such as pachinko balls and exchange medals.

[0002]

2. Description of the Related Art Game media such as pachinko balls and exchange medals have a phenomenon in which, as they are used, hand dust, dust, or cigarette ash or fat adheres to them, or rust occurs and gradually deteriorates. . Conventionally, in order to clean such a dirty game medium, a method of putting it in a cleaning liquid to clean and dry it, or mixing it with a leather or cloth piece containing a cleaning component to clean it has been adopted.

However, recently, with the automatic systemization and labor saving of gaming machines, the game medium has been converted into a mechanism that is closed cycled in the system, and the cleaning means is also incorporated in the system for purification. There is a need for a dry cleaning system that automatically treats as it passes through the equipment.

Conventionally, as a cleaning agent for game media applied to a dry cleaning means, for example, an elastic granular material obtained by mixing silicone oil with vinyl chloride resin or / and synthetic rubber (Japanese Patent Laid-Open No. SHO11-96).
No. 47-24170), or a mixture of a water absorbent resin and a granular material containing a water absorbent resin as a main material and a glass short fiber abrasive. Further, a chip in which a glass short fiber abrasive is mixed with a synthetic resin such as 6-nylon (Japanese Patent Laid-Open No. 55-1574).
69), or granules containing 6-nylon as a main component (JP-A-59-124563).

[0005]

However, among the above-mentioned conventional techniques, the detergent containing short glass fibers as an abrasive has the short glass fibers liberated as it is used and adheres to the game medium and comes into contact with the skin. There is a risk of polluting the environment inside the game hall. In addition, a detergent containing a synthetic resin as a main ingredient is required to have an antistatic function so as to prevent dust from recontaminating and to have an appropriate hardness in order to enhance the cleaning effect.

[0006] In this respect, 6-nylon resin is an excellent material for a cleaning agent for game media because it has appropriate water absorption and tackiness, but the glossiness of the game media after purification is insufficient. Besides, there is a drawback that the material cost becomes high.
Therefore, there is a demand for the development of an industrially advantageous material that has a high cleaning function in place of 6-nylon.

As a result of intensive studies conducted by the present inventors on a cleaning agent for game media satisfying the above requirements, synthetic resin particles containing short collagen fibers have an excellent cleaning action equivalent to or better than that of 6-nylon. It was confirmed that the above results were exhibited, and the present invention was completed.

Therefore, an object of the present invention is to provide a cleaning agent for game media which has excellent cleaning and durability properties and is inexpensive.

[0009]

Means for Solving the Problems The cleaning agent for game media according to the present invention for achieving the above object is composed of a granular synthetic resin composition containing a fine collagen-containing substance. It is a feature.

In the present invention, the fine collagen-containing substance is a substance obtained by miniaturizing collagen having a fiber structure which is a constituent of natural leather, and is a main component composed of various proteins. In addition to the collagen of the above, it refers to those containing polysaccharides, lipids and the like. The collagen-containing substance is preferably as fine as possible in order to form a uniform mixed composition with the synthetic resin component. For example, for industrial reasons, the collagen-containing substance is ultrafinely divided into micron units. A synthetic resin and a shell that is a by-product when processing tanned leather.
Bing leather scraps may be pulverized to a desired size.

The cleaning agent for game media of the present invention is constituted by blending such a fine collagen substance into a synthetic resin. The synthetic resin blended with the collagen-containing substance is as follows:
For example, polyolefin resin such as polyethylene and polypropylene, polyvinyl chloride resin, polyester resin,
Polyamide resin, organosilicone-containing resin, fluororesin, vinyl acetate resin, chlorinated polyethylene resin, polyacetal resin, polystyrene resin, AES resin, AS
One or more of resins, ABS resins, ACS resins, ethylene-vinyl chloride copolymer resins, ethylene-vinyl acetate copolymer resins, synthetic rubbers and the like can be mentioned. However, olefin resins are particularly preferably used for the purpose of the present invention.

The amount of the collagen-containing substance mixed with the synthetic resin varies depending on their physical properties and the type of game medium, but in many cases, it is in the range of 10 to 70% by weight, preferably the total weight of the synthetic resin. It is 20 to 50% by weight. If the blending amount is less than 10% by weight, the water-holding property and flexibility of the collagen-containing substance will be insufficient, and it will not be possible to impart appropriate hardness and antistatic properties to the synthetic resin, so that the cleanability of the game medium will be reduced. On the other hand, if it exceeds 70% by weight, the durability as a detergent is insufficient and the inconvenient result of releasing collagen fiber is brought about.

The cleaning agent for game media according to the present invention is basically composed of the above-mentioned two kinds of materials, and if necessary, an inorganic filler, a plasticizer, a surfactant, a stabilizer, a colorant,
One or two kinds of bactericides and lubricants can be blended in appropriate amounts.

As the inorganic filler, fine powder having a Mohs hardness of 5 or more, preferably 5 to 9 is used. Examples of this type of inorganic substance include chromium oxide, alumina, dicalcium phosphate, silica, aluminosilicate, aluminum silicate, calcium silicate, barium sulfate, and the like, but are not limited to these substances. It is not something that will be done. When the inorganic filler is compounded, the amount ratio is set to 5% by weight or less, preferably 0.5 to 1.5% by weight, based on the total weight of the synthetic resin. If the blending amount exceeds 5% by weight, the result is that the game medium is abraded and worn.

Further, as the plasticizer, for example, phthalic acid esters such as DOP, aliphatic dibasic acid esters, phosphoric acid esters, epoxy plasticizers, etc., and as the stabilizer, sulfur antioxidants, Organotin stabilizers, phosphites, phenolic antioxidants, etc. may be used as lubricants.
Metal soaps, hydrocarbons, higher fatty acids, higher fatty acid amides, higher alcohols, higher fatty acid esters,
Polyhydric alcohol esters and the like can be used respectively.

The above-mentioned fine collagen-containing substance, synthetic resin and additives to be blended if necessary are sufficiently kneaded while heating with an appropriate kneading machine to form a uniform composition, and then a molding machine is used. In the case of a shape corresponding to the type of game medium, for example, a pachinko ball, it is molded into a granule having a diameter smaller than that of the pachinko ball to make a cleaning agent. At this time, it is preferable that the granule characteristics have a spherical shape and a particle size distribution so that the pachinko balls can be packed most closely.

The cleaning agent for game media composed of the granular synthetic resin composition thus obtained can be directly used in a purifying device incorporated in an automatic circulation system for game media, which changes the conventional cleaning process. It is possible to effectively purify the game medium.

[0018]

The cleaning agent for game media according to the present invention is basically composed of a granular synthetic resin composition comprising a fine collagen-containing substance and a synthetic resin. Among them, the collagen-containing substance is mainly composed of collagen and oil and fat components of the fiber structure, and has appropriate water content and water retention property, so that it effectively removes the dirt and dust attached to the game medium at the use stage. Functions to remove and clean. On the other hand, the synthetic resin containing collagen-containing substance possesses appropriate flexibility and hardness, and further enhances the cleaning action when it comes into contact with the game medium, while preventing electrostatic charging under friction during the cleaning operation. It functions to prevent recontamination of dust. These actions synergize to allow safe and effective cleaning of game media, especially pachinko balls.
