Description

TECHNICAL FIELD The present invention relates to a pachinko ball polishing apparatus for removing dirt from the surface of a pachinko ball for cleaning.

"Conventional technology" As a conventional pachinko ball polishing technology, for example,
54-34198, Japanese Patent Publication No. 55-8308, Japanese Patent Publication No. 52-15093, and the like.

In the technology disclosed in each of the above publications, a small granular abrasive made of a mixture of a water-absorbent synthetic resin material, an oil-absorbent synthetic resin material, and a hard material is used as a material for polishing, and it is stirred with a pachinko ball. The surface dirt is adsorbed by these small particles for polishing to be cleaned.

The dirty material used should be cleaned separately using a dedicated washing machine, or instead of being washed, the dry particles should be stirred and rubbed together to scrape and clean the surface for reuse. there were.

[Problems to be Solved by the Invention] Although such conventional techniques are widely used today, there are the following problems to be solved.

That is, (1) the abrasive made of a synthetic resin material or the like has a self-dusting property in which the surface is peeled off by being vigorously scratched together with a pachinko ball, and a step for removing this dust is required.

(2) Separation of pachinko balls and abrasives is quite troublesome and requires a large space.

(3) Since the abrasive is small particles, a dedicated washing machine for washing and drying the abrasive is required.

Further, in the case of regrinding in a dry state, a dedicated regrinding device is required, and in this case, the abrasion of the abrasive material is considerably increased.

(4) Since the abrasive is small particles, it is difficult to take antistatic measures to prevent redeposition of dust.

The present invention has been made by paying attention to such conventional problems, and since it has no self-dusting property and can be used as a conveyor belt, it does not take up a lot of space and requires a dedicated washing machine or a recycler. An object of the present invention is to provide a pachinko ball polishing device that does not require a polishing device and is easy to take measures against static electricity.

"Means for Solving the Problem" The gist of the present invention for achieving such an object is to provide a pachinko ball polishing apparatus installed in an island of a pachinko game machine, wherein the polishing apparatus is the pachinko game machine It is placed below the out ball outlet, the upper part is fully opened to accept all the pachinko balls discharged from the out ball outlet, and the polishing device is made of a long cloth made of synthetic resin fiber cloth that absorbs water and oil. The belt-shaped polishing cloth and a plurality of pushing parts for moving the pachinko balls from the surface of the polishing cloth at a height corresponding to the radius of the pachinko balls in the longitudinal direction of the island to push the pachinko balls. It exists in a pachinko ball polishing machine.

"Operation" A large number of pachinko balls are pushed onto a belt-shaped polishing cloth that is placed horizontally or tilted upward or downward in the longitudinal direction and left stationary, or movable against the direction of travel of the pachinko balls. It is pushed by and moves.

While the pachinko balls move on the polishing cloth, the pachinko balls roll intricately due to collision between the pushing parts and the pachinko balls, and the dirt on the surface of the polishing cloth is wiped away.

Since the polishing cloth is made of ultrafine synthetic fibers that are highly water-absorbing and oil-absorbing, the surface of the pachinko balls that rolls or rubs off the surface of the pachinko balls is wiped of oil, water and dust.

Since the polishing cloth has a cloth shape, it does not generate dust by itself, and since it is made in a belt shape, it is easy to remove and clean, and it is not worn because it is not scraped for regeneration.

Further, since it has a belt shape, it can be used not only as a polishing function but also as an operation belt for pachinko balls, which saves space.

Further, it is possible to extremely easily implement countermeasures against static electricity, such as grounding the belt or a member in contact with the belt.
