Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for polishing pachinko balls by continuously supplying a small amount of cleaning liquid into a polishing chamber and then rotating a brush.

There are various conventional methods and devices for polishing pachinko balls by rotating a brush.

However, in the conventional method, when pachinko balls with relatively little dirt were polished, they sometimes became dirty.

When the cause of this was investigated, it was discovered 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 balls. 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.

As a means to reduce dirt on the brush itself, it has been proposed in the past to increase the number of bristles in the brush or to frequently replace the brush with a new one. However, from the table, it is difficult to significantly increase the number of bristles on a brush due to its structure and installation space, and it is cumbersome to frequently replace the brush itself. It's nothing like a plan.

The present invention was proposed in view of the above, and by injecting a small amount of cleaning liquid into a polishing chamber that has a rotatable brush inside and polishing the pachinko ball with a brush from the beginning, it can efficiently polish pachinko balls and remove dirt such as dust. It is an object of the present invention to provide a method and apparatus for polishing pachinko balls that can efficiently discharge the brush to the outside of the polishing chamber and keep the brush in a clean state at all times.

The present invention will be explained below based on embodiments shown in the drawings.

The polishing apparatus shown in FIG. 1 has a horizontally long cylindrical polishing tube. One opening is closed by a first lid member 3, and the other opening is closed by a second lid member l. A polishing brush 6 is inserted into the polishing chamber S, and one end of the shaft 7 of the brush 6 is connected to the first bearing of the first lid member 3. (2) The other end is rotatably supported by a second bearing of the second lid member 3, and a motor is connected to the shaft end protruding from the first lid member 3 via a joint /θ. Connect a drive source such as

The polishing cylinder is a cylinder with a circular cross section, and a ball supply port is provided on one side of the bottom surface, and a long ball holding member /3 is installed at the middle of the height of the inside surface to extend the length of the polishing cylinder λ. It is installed along the horizontal direction.

Each polishing tube is installed so that one end with the ball supply port is slightly higher than the other end.

The polishing brush 6 has a long shaft 7 with numerous elastic bristles radially implanted on the curved surface thereof, and when inserted into the polishing cylinder, the polishing brush 6 touches the inner surface of the polishing cylinder. The distance between the tip of the hair and the tip of the hair is as short as the diameter of a pachinko ball.
Set the length.

Therefore, when the polishing brush 6 is rotated by the drive of the motor // in the direction of the arrow in FIG. It is held under the holding member 3, and in this state the surface of the dirty Pachinko ball can be rubbed and polished. Note that the pachinko balls A move along the ball holding member /3 from the ball supply rotor side to the second lid member side, and are continuously polished during this movement. Then, when it moves to the second lid member d, it is polished t'
Lfc pachinko balls are discharged from a ball discharge port 15 provided in the lid member.

When the surface of the dirty pachinko ball A is polished with a brush, the dirt adhering to the surface of the pachinko ball is removed, and the brush 6
The bristles 1... of the brush 6 are worn out, and these dirt and abrasion particles adhere to the bristles/glue of the brush 6 or to the inner surface of the polishing chamber S.

Therefore, in the present invention, the above-mentioned dirt and abrasion powder are discharged to the outside of the polishing chamber 5 using the cleaning liquid from the cleaning liquid supply device 16. The cleaning liquid supply device /6 connects the upper end inlet of the liquid supply pipe /7 to the tank lIK, and the lower end outlet to the drip hole /9 which is opened near the inclined upper end of the polishing cylinder. A flow control valve -〇 is installed in the middle of the tank/
A small amount of cleaning liquid is intermittently supplied from the drip hole 19 to the polishing chamber 5.
It is supplied to the inside 6-. Note that the cleaning liquid may be any liquid, such as water or methanol, as long as it can remove dirt, but it is desirable that it be harmless and have good volatility. In addition, if a small amount of cleaning liquid is continuously dripped into the polishing chamber 5 from the cleaning liquid drip hole, the cleaning liquid that has fallen onto the brush B will remove dirt and abrasion particles attached to the surface of the bristles. At the same time, the cleaning liquid scattered by the rotation of the brush t washes away the dirt on the inner surface of the polishing cylinder to the bottom of the polishing cylinder. Further, the cleaning liquid wets the surface of the pachinko ball A to prevent the generation of static electricity and promote the removal of dirt. The cleaning liquid contaminated as described above, including dirt from the pachinko ball A and abrasion powder from the brush 6, flows toward the left side in Figure 1 due to the downward slope of the polishing cylinder, and is drained into the cleaning liquid drain which is opened at the lower end of the slope. It is discharged to the outside of the polishing chamber S from the outlet 21.

Therefore, the brush 6 and the inner surface of the polishing chamber S are always maintained in a clean state, the pachinko balls can be efficiently polished, and the noise during polishing can be reduced compared to the conventional technique.

-7- The amount of cleaning liquid supplied varies depending on the amount of pachinko balls supplied and the state of dirt, but it may be small enough to discharge the dirt to the outside of the polishing chamber S. According to experiments, 10-50cc per minute
A sufficient cleaning effect could be brought about by supplying a certain amount.

The pachinko balls polished as described above are moist because a small amount of cleaning liquid has adhered to the surface.

Therefore, these pachinko balls are introduced into the drying chamber through the ball outlet/3 and dried.

The embodiment of the drying chamber 22 shown in FIG. The drying cylinder 23 is slightly inclined downward in accordance with the slope of the polishing cylinder. And this drying room 2
A drying brush J5 is inserted into the inside of the plastic brush J5, one end of the shaft on the left side of the plush brush J5 is connected to the shaft end of the polishing brush 6, and the other end is connected to the fifth bearing 27 of the two sixth lid members. The drying brush 2S is supported to rotate integrally with the polishing brush 6. In addition, the drying tube, 23 on the slope JP-A-Sho GO-9
6280(3) A duct 9 of a warm air blower-g is connected near the end, and a ball discharge port 3o is opened at the lower end of the slope.

Therefore, the pachinko ball A polished in the polishing chamber 5...
When the ball enters the drying room through the ball outlet/S in a wet state, the hot air supplied from the blower 2g dries the surface of the pachinko ball, and the rotating drying brush 2S dries the surface of the pachinko ball. To speed up rubbing and drying and at the same time polish the pachinko ball surface again. The pachinko balls that have been dried and repolished in this way are dried with a drying brush 2! r rotation and drying cylinder, 2
3, the ball is transferred to the third lid member side by the downward slope, and is discharged from the ball discharge port 30.

By arranging the bristles on the left side of the polishing brush 6 and drying brush 2 in a spiral in the length direction of each shaft 7, 2A, pachinko balls can be transferred efficiently. Also, the cleaning liquid discharged outside the polishing chamber S may be disposed of into the sewer via the drainage channel 3/, but it can be passed through a filter (not shown) and returned to the tank/g for circulation. You can do it like this.

In another embodiment of the polishing apparatus shown in FIG. The opening is connected to the fourth lid member 33.
The polishing chamber 3' is closed by closing the drying cylinder 3'.
The upper opening is closed with the fifth lid member 3'l, and the drying chamber 2 is closed.
2', a polishing brush 6' is placed in the polishing chamber S', and a drying brush j! is placed in the drying chamber L2'. ' are inserted in the longitudinal direction, and the motor II' is connected to the lower end of the shaft 7' of the polishing brush 6' supported by the fourth bearing 3s and the fifth bearing 36,
A conductive pulley 37a is attached to the shaft 7' of the polishing brush 6' and the shaft roller' of the drying plastic j'.

Pass the endless conductive belt to 39b. And polishing room 5
' communicates the upper end of the drying chamber 22' with the upper end of the drying chamber S' through a communication passage 39, and a ball supply lower 2' is provided in the lower part of the polishing chamber S'.
A liquid supply pipe/7' of a cleaning liquid supply device 76' is connected above the ball supply lower 2'. On the other hand, a ball outlet 30' is provided in the lower part of the drying chamber, and a duct 29' of a hot air blower 3' is connected above the ball outlet 30'.

When dirty pachinko balls are fed into the polishing chamber S' from the ball supply port /2', the polishing brush 6', which has countless bristles arranged in a spiral pattern, is driven by the motor //'. It rotates more and polishes the pachinko balls while transporting them. While the polishing brush 6' is transporting and polishing the pachinko ball, a small amount of cleaning liquid is constantly supplied from the cleaning liquid supply device 76' into the polishing chamber 3' to remove the bristles of the polishing brush 6' and polish the pachinko ball. Clean the dirt n1 abrasion powder etc. adhering to the inner surface of the cylinder 2' in the polishing chamber S.
