Abstract

PURPOSE:To eliminate self-dusting characteristics from polishing cloth, and also, to facilitate a replacement by pushing and feeding a pachinko ball by a blade of a screw tube rotated in a polishing cylinder, rubbing it against the polishing cloth which is installed along an inner wall of the polishing cylinder and is excellent in water absorbency and oil absorbency and grinding it. CONSTITUTION:In a grinding cylinder 1, polishing cloth 5 is inserted along its inner wall, and also, a screw tube 6 having a blade 10 of a suitable pitch for rotating in the direction as indicated with an arrow A around an axis of the polishing cylinder 1 is installed. Between the inside surface of the polishing cloth 5 and the surface of the screw tube 6, a clearance being roughly equal to or a little smaller than the diameter of a pachinko ball 2 is provided, and the pinball 2 thrown into the polishing cylinder 1 from a throw-in port 3 is rubbed against the polishing cloth, while being pushed and fed by the blade 10 and polishing is executed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball polishing apparatus for removing dirt from the surface of a pachinko ball for cleaning.

[0002]

2. Description of the Related Art Conventionally, generally, a spiral is rotated in a cylindrical tube having a spiral, a small granular abrasive made of resin and a pachinko ball are agitated, and dirt on the surface of the pachinko ball is adsorbed to the abrasive. Had been cleaned. Abrasives should be changed regularly,
The soiled abrasive was separately washed with a dedicated washing machine and reused.

[0003]

However, there are the following problems in such a technique which is generally used at present.

1) Separation of the abrasive from the pachinko balls is relatively difficult and requires a device and a place therefor.

2) Since the abrasive material is made of resin, it has a self-dusting property in which the surface of the abrasive material itself is separated by vigorous stirring with a pachinko ball, and there is a possibility of re-adhesion to the pachinko ball due to static electricity or the like.

3) Since the abrasive is a small particle, it needs to be taken out in a state of being mixed with the pachinko balls at the time of replacement and it needs to be separated separately, and it is very troublesome, and a cleaning machine dedicated to cleaning and drying the dirty abrasive is required. Need.

The present invention has been made to solve the above-mentioned problems, has no self-dusting property, can be easily replaced, and can be used as a pachinko ball with a polishing cloth without using a dedicated washing machine. An object of the present invention is to provide a pachinko ball polishing apparatus that polishes and cleans the surface of.

[0008]

In order to achieve this object, a pachinko ball polishing apparatus of the present invention is provided with a cylindrical tubular polishing cylinder and a removable inner wall of the polishing cylinder. And a polishing cloth with excellent properties, which is rotatably provided in the polishing cylinder, and pushes the pachinko balls to the surface with a gap that is approximately equal to or slightly smaller than the diameter of the pachinko balls between the polishing cloth inner surface and the polishing cloth. And a screw tube having spiral blades with an appropriate pitch.

[0009]

In the pachinko ball polishing apparatus of the present invention having the above-mentioned structure, the pachinko balls charged into the cylindrical tubular polishing cylinder are rotated by the screw tube provided in the polishing cylinder. The spiral blades on the surface are pushed forward while rotating along the inner wall of the polishing cylinder. At that time, the pachinko ball is rubbed with a polishing cloth inserted so that the inner wall surface of the polishing cylinder is almost equal to the diameter of the pachinko ball between the inner surface of the polishing tube and the screw tube surface, and the blade moves or moves. , Pachinko balls rotate intricately due to collisions with each other, and water, oil and fat, dust, etc. adhering to the surface are wiped off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic structure of an embodiment of the present invention.
Shows the shape of the polishing cloth, and FIG. 3 shows the cross section of the polishing portion.

A cylindrical tubular polishing cylinder 1 is installed horizontally on the ground. The polishing cylinder 1 is provided with an inlet 3 and an outlet 4 for pachinko balls 2 near both ends of the polishing cylinder 1. Both ends of the polishing cylinder 1 are sealed to prevent the pachinko balls 2 from flowing out. Inside the cylindrical tube 1, a polishing cloth 5 and a screw tube 6 are installed.

The polishing cloth 5 is made of a synthetic resin having excellent water absorbency and oil absorbency, and its length is substantially equal to the inner circumference of the polishing cylinder 1 and its width is substantially equal to the length of the cylindrical tube 1, as shown in FIG. It is adhered to the thin guide plate 7 as shown in FIG. Polishing cloth 5 adhered to the guide plate 7
Is a cutout portion 1 provided in the polishing cylinder 1 as shown in FIG.
It is inserted from a along the inner wall of the polishing cylinder 1, and when the polishing cloth 5 covers the entire circumference, the guide plate 7 and the polishing cylinder 1 are fixed by the fixing metal fitting 8.

The screw tube 6 is rotated around the center of the polishing cylinder 1 by a screw motor 9 in the direction of arrow A in FIG. 1, and has spiral blades 10 with an appropriate pitch on the outer circumference. Between the inner surface of the polishing cloth 5 and the surface of the screw tube 6, a diameter of the pachinko balls 2 is almost equal to or slightly smaller than the diameter, and the diameter of the blade 10 is equal to the inner diameter of the polishing cloth 5. It is set a little small.

Next, the operation will be described.

Pachinko balls 2 discharged from each pachinko machine
Are collected from the out gutter 11 and from the inlet 3 to the polishing cylinder 1
It is thrown in.

Since the screw tube 6 is rotated in the direction of the arrow A in FIG. 1 by the screw motor 9 in the polishing cylinder 1, the pachinko ball 2 is rotated by the blades 10 attached to the screw tube 6 as shown in FIG. Is pushed in the direction of arrow B.

When the pachinko balls 2 are pushed, they are rubbed against a polishing cloth 5 inserted into the inner wall of the polishing cylinder 1, and the polishing cloth 5 wipes off water, oil and fat, dust, etc. on the surface of the pachinko balls 2. .

When the pachinko balls 2 have finished passing through the polishing cylinder 1, the entire surface is completely cleaned and discharged from the discharge port 4.

The polishing cloth 5 which has been soiled by wiping dust off the surface of the pachinko balls 2 is removed and replaced with a clean product after the soiling is sufficiently adhered. Contaminated products are washed with water and reused.

[0021]

As described above, according to the pachinko ball polishing apparatus of the present invention, the pachinko balls are pushed by the blades of the screw tube rotating in the polishing cylinder and inserted into the inner wall of the polishing cylinder. Since it is configured to rub against a polishing cloth that excels in water absorption and oil absorption, the polishing cloth does not generate dust, and can be replaced easily. Does not require a washer.
