Description: TECHNICAL FIELD The present invention relates to a pachinko ball polishing apparatus for polishing an out ball from a pachinko island stand with an abrasive, and particularly to a pachinko ball that does not require a wide island stand. The present invention relates to a ball polishing device.

[Conventional technology]

In general, out balls from each pachinko machine on Pachinko Island stand are dirty with hand marks etc. and cause clogging etc.,
This must be polished constantly or periodically. Therefore, conventionally, a method has been adopted in which a pachinko ball polishing device also serving as a pachinko ball lifting device is used, and polishing is performed during lifting of the out ball.

[Action]

In the pachinko ball polishing apparatus according to the present invention, at the time of pachinko ball polishing, the passage between the first unit outlet and the second unit inlet is opened by the opening / closing means. In this state, when the pachinko balls (out balls) collected from the pachinko island stand are guided to the first unit from the inlet, the pachinko balls are pumped out of the first unit from the outlet, and are polished in the meantime. Polished by material. The pachinko ball and the abrasive coming out of the outlet of the first unit are separated by the first separating means when there is a space in the storage section, and the abrasive is stored in the storage section, and the pachinko ball passes through the passage. To the inlet of the second unit. On the other hand, when the reservoir is filled with polishing, the pachinko ball and the abrasive material are the first.
It is not separated by the separating means, but is led to the inlet of the second unit through the passage as it is. The pachinko balls and the abrasives led to the second unit are pumped toward the outlet in the second unit, and the pachinko balls are polished during the period. The pachinko ball and the abrasive coming out of the outlet of the second unit are separated by the third separating means, and only the abrasive is removed from the first unit.
You are led to the entrance of the unit. The pachinko balls are lifted to a position above the pachinko island stand by, for example, a bucket type lifter and distributed to the respective pachinko machines.

On the other hand, at the time of polishing regeneration and discharge of the abrasive in the storage section, the passage is closed by the opening / closing means. Therefore, the first

At the time of polishing regeneration and discharge of the abrasive, since the inside of the storage portion is usually filled with the abrasive, the pachinko balls and the abrasive are not separated by the second separating means at first, but pass through the circulation path as they are. To the inlet of the first unit. When the polishing regeneration of the abrasive by the abrasive regenerating means and the discharge of the abrasive from the abrasive outlet are started, the amount of the abrasive in the storage portion is gradually reduced, so that a space is formed in the storage portion. The pachinko balls and the abrasive are separated by the second separating means, the abrasives are stored in the storage section, and the pachinko balls are guided to the inlet of the first unit through the circulation path. The abrasive polished and regenerated by the abrasive regenerating means is guided to the inlet of the second unit and pumped through the second unit, and the abrasive discharged from the outlet of the second unit is separated by the third separating means. Through the inlet of the first unit. That is, at the time of polishing and regenerating the abrasive, the pachinko ball is polished by circulating through the first unit and the circulation path, and at this time, the second unit functions only as a conveying path of the abrasive. Also, the supply of new pachinko balls from Pachinko Island to the first unit will be suspended.

It has become. The out ball 26 discharged to the outside of the third separating device 17 is guided to a bucket type lifter 39 as shown in FIG. It is designed to be lifted to an upper space (not shown).

As shown in FIG. 1, a container-shaped dust-absorbing unit 41 in which the abrasive 28 separated by the pen 17a falls on an inclined net plate 41a disposed at the upper end opening is provided inside the third separating device 17. The dust suction unit 41 is installed, and is connected to the dust suction box 35. The dust separated from the abrasive 28 by dropping on the inclined netting plate 41a is
After that, the dust is collected by the dust bag 35a in the dust box 35.

 Next, the operation of the present embodiment will be described.

 First, the operation at the time of polishing the out ball 26 will be described.

In this case, the shutter 38 is driven by the operation of the solenoid 37.
Are driven in the opening direction, and the passage 14 is open.

In this state, the inlet 20a of the first unit 11 is
When the out ball 26 is guided, the spiral feeder 22 is rotationally driven by the motor 24, so the out ball 26 supplied into the cylinder 20 from the inlet 20a is transferred to the outlet 20b together with the abrasive 28. It is pumped toward. During this time, the polishing material 28 comes into contact with the polishing material 28 many times and is polished.

Out ball 2 pumped to outlet 20b of first unit 11
First, the abrasive 6 and the abrasive 28 are guided to the first separation device 13. At this time, if there is space in the storage box 18,
The abrasive 28 is stored in the storage box 18 and the out ball 26 is guided to the inlet 21a of the second unit 12 via the passage 14. On the other hand, after the inside of the storage box 18 is filled with the abrasive 28, it is not separated by the cage 15a, and the out ball 26 and the abrasive 28 come together and pass through the passage 14 through the second unit 12
To the inlet 21a.

The out ball 26 and the abrasive 28 supplied into the cylindrical body 21 from the inlet 21a of the second unit 12 pass through the cylindrical body 21 because the spiral feeder 23 is driven to rotate by the motor 25.
It will be pumped to 21b. Here, while only the out ball 26 is supplied, the second unit 12 merely has a pumping function.
Is supplied, the outer ball 26 has a polishing function. In other words, the out ball 26 comes in contact with the abrasive 28 many times while the second unit 12 is pumped, and is polished again.

The out ball 26 and the abrasive 28 which have been pumped to the outlet 21b of the second unit 12 are supplied from the outlet 21b to the third separation device 1
7 falls on the pen 17a, and the ball 17
And the abrasive 28 are separated. And out ball 26,
It is rolled on 17a and discharged out of the third separating device 17, and further discharged to the upper space of the island stand by a bucket type lifter 39 and distributed to each pachinko machine 2. On the other hand, the abrasive 28 drops on the inclined net plate 14a after passing through the cage 17a, and the dust attached to the abrasive 28 is separated by the impact, and is captured in the dust-absorbing unit 41. Since the inside of the dust suction unit 41 is sucked by the dust suction motor 36, the dust suction box 35
The dust is collected by the dust bag 35a. The abrasive 28 rolls on the inclined net plate 41a and is guided to the inlet 20a of the first unit 11.

Thus, the out ball 26 can be polished using the lower island space 4 of the pachinko island stand 1, and the pachinko island stand 1 can be polished.
Need not be wide. In addition, X of both units 11 and 12
Because it is arranged in a shape, the lower part of the island is only about 60cm 4
Inside, a polishing passage having a length substantially the same as or longer than that of the conventional ball-shafting / lifting machine 5 can be secured.

Next, operations during polishing and discharge of the abrasive 28 stored in the storage box 18 will be described.

In this case, the shutter 38 is driven by the operation of the solenoid 37.
Is driven in the closing direction, the passage 14 is closed, and each pachinko machine 2 outputs a new out ball.
26 is not guided to the inlet 20a of the first unit 11.

When polishing the abrasive 28 stored in the storage box 18, both the units 11 and 12 are started in the above-described state, and the shutter 31 is opened to start the abrasive regenerating machine 19. Then, the out ball 26 and the abrasive 28 in the first unit 11
Is discharged from the outlet 20b and guided to the first separation device 13.

Here, the passage 14 is closed by the shutter 38, and at the beginning of the operation of the abrasive regenerating machine 19, the abrasive 28 in the storage box 18 does not decrease so rapidly, so that there is no space in the storage box 18. It has become. Because of this, out ball 26 and abrasive
28 accumulates on the bed 13a of the first separation device 13 and is eventually led to the second separation device 15 over the height difference from the first separation device 13.

Out ball 26 and abrasive material guided to second separation device 15
28 is a second separation device until space is created in the storage box 18.
It is not separated even at 15, and is led to the inlet 20 a of the first unit 11 via the circulation path 16.

On the other hand, when the abrasive 28 in the storage box 18 is guided and reduced by the abrasive regenerating machine 19, a space is formed above the storage box 18. For this reason, the out ball 26 and the abrasive 28 guided to the second separation device 15 are thereafter separated by the paddle 15a, the abrasive 28 is stored in the storage box 18, and the out ball 26 passes through the circulation path 16. Through the inlet 20 a of the first unit 11.

In addition, since the pachinko balls do not flow into the passage 14 during polishing and regeneration of the abrasive, the abrasive 28 polished by the abrasive regenerating machine 19 is smoothly discharged from the outlet to the passage 14, and the second unit 12
After being led to the inlet 21a, the inside of the cylindrical body 21 passes through the outlet 21b.
Will be pumped up. Then, the abrasive 28 discharged from the outlet 21b passes through the cage 17a of the third separator 17 and is led to the inlet 21a of the first unit 11. The dust removed by the polishing and regenerating machine 19 is captured by the dust receiver 33 and finally collected by the dust bag 35a in the dust box 35.

By the way, the polishing and regeneration of the polishing material 28 by the polishing material regenerating machine 19 was performed by supplying a certain amount or more of the polishing material 28 in a short time, rather than supplying the polishing material 28 to the polishing material regenerating machine 19 little by little. A larger polishing and regenerating effect can be obtained, and the polishing and regenerating operation can be completed in a short time. For this reason,
In the case of this embodiment in which the abrasive 28 is stored in the storage box 18 and sent to the abrasive regenerating machine 19 at once during polishing and regeneration, an improvement in polishing and regeneration efficiency can be expected.

On the other hand, when discharging the abrasive 28 in the storage box 18, the shutter 31 is opened with the shutter 29 closed. Then, the abrasive 28 in the storage box 18 is discharged to the outside from the abrasive outlet 30 and the abrasive 28 in both the units 11 and 12 is discharged.
Is separated from the out ball 26 by the second separation device 15 and
Quickly recovered within.

Since the abrasive 28 stored in the storage box 18 is regenerated and discharged by polishing, the polishing regeneration efficiency and discharge efficiency are extremely high.

〔The invention's effect〕

As described above, according to the present invention, a pachinko ball polishing apparatus can be installed without increasing the width of the pachinko island stand, and a polishing effect equivalent to or higher than that of a conventional ball polishing / lifting machine can be obtained.

In particular, in the present invention, since the pachinko ball does not pass through the passage on the front surface of the abrasive regenerator during the polishing and regenerating of the abrasive, the flow adjusting member of the polishing regenerator is pushed by the ball and the outlet is closed as in the related art. Thus, the problem that the reclaimed abrasive can be smoothly discharged to the second unit inlet can be solved.

In addition, when the polishing material is regenerated and discharged, the polishing material is stored in the storage section in advance, so that the polishing regenerating efficiency and the discharging efficiency can be improved.
