Abstract

PROBLEM TO BE SOLVED: To attain size reduction, reduce a noise generated at cleaning time, and prevent a wasteful use of electric power by forming a clearance capable of passing a single pachinko ball between it and a cleaner sheet, and arranging an outflow restricting means of a pachinko ball in the vicinity of an outer periphery of an inner cylinder arranged so as to be opposed to a rotary board. SOLUTION: In a pachinko ball cleaner 70, a cleaner sheet 11 is installed on a rotary board 10 driven in rotation by a motor 7, and a clearance G1 capable of passing at least a single pachinko ball 2 is formed between it and this cleaner sheet 11, and an inner cylinder 3 is arranged so as to be opposed to the rotary board 10. An outer cylinder 12 as an outflow restricting means to restrict the outflow of a pachinko ball is arranged near an outer periphery of this inner cylinder 3. Therefore, the pachinko ball 2 introduced to the inner cylinder 3 can be efficiently cleaned while contacting with the cleaner sheet 11. The pachinko ball 2 can be reliably cleaned since the outflow is restricted by the outer cylinder 12.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of a pachinko ball cleaner according to the present invention will be described with reference to the drawings.
In FIGS. 1 and 2, the pachinko ball cleaner indicated by reference numeral 70 has a frame 60 including a bottom plate 4 and side walls 5, 5 rising vertically from front and rear edges of the bottom plate 4. The chassis 6 is fixed in the frame 60 in parallel with the bottom plate 4. The chassis 6 may be formed in a trapezoidal shape as shown in the figure and fixed to the bottom plate 4, or the edge of the plate may be bent and the edge fixed to the side walls 5 and 5 of the frame 60. For example, it is fixed by an appropriate fixing means.

A motor 7 as a drive source is fixed to the lower surface of the chassis 6 via the chassis 6. The motor 7 is a motor with a reduction gear, and the output shaft 8 of the motor 7 extends vertically above the chassis 6 through the chassis 6. A disk-shaped rotary disk 10 is fixed to the output shaft 8 via a hub 9. Therefore, the rotating disk 10 is driven to rotate by the motor 7. The rotation of the rotating disk 10 is for removing dirt from the pachinko balls 2. The details of the dirt removal operation of the pachinko ball 2 will be described later.

An appropriate number of rollers (not shown) may be brought into contact with the lower surface of the rotating disk 10. Each of the rollers receives a load applied to the rotating disk 10 and is used to prevent the load from being directly applied to the output shaft 8, so that the rotation of the rotating disk 10 is not hindered. The turntable 10 is rotatably supported in a tangential vertical plane. Each roller can be rotatably supported by, for example, an angle material rising from the chassis 6.

A disk-shaped cleaner sheet 11 having substantially the same diameter as the rotary disk 10 is fixed to the upper surface of the rotary disk 10. The cleaner sheet 11 is for directly removing dirt from the pachinko balls 2, and may be made of any material as long as it can remove dirt from the pachinko balls 2. The shape of the contact surface with the pachinko ball 2 is, for example, a smooth sheet, woven, nonwoven, mesh, sponge, small hole, slit or groove. Appropriate ones such as formed ones can be arbitrarily selected and used. Further, a small amount of fats and oils and a rust preventive liquid agent may be added to the cleaner sheet 11 in order to impart gloss and lubricity to the pachinko balls 2 and prevent rust.

When there is a possibility that the cleaner sheet 11 is deformed during use depending on the material, it may be used by attaching it to a core 18 with a double-sided tape or an adhesive, for example, as shown in FIG. In this case, if the cleaner sheets 11 are attached to both sides of the core member 18, if one of the cleaner sheets 11 becomes dirty, the cleaner sheet 11 can be turned over and the other cleaner sheet 11 can be used, which is very economical.

In order to prevent the cleaner sheet 11 from deviating from the rotating disk 10 during use, as shown in FIGS. 1, 3 and 4, the upper surface of the rotating disk 10 is formed in a concave shape. The cleaner sheet 11 is mounted on the concave upper surface. Alternatively, as shown in FIG. 5, the displacement of the cleaner sheet 11 can be prevented by attaching a plurality of claws 10 a to the outer periphery of the turntable 10. Further, as shown in FIG. 6, one projection 10b is provided at the center of the turntable 10, or a plurality of protrusions (not shown) are provided near the center of the turntable 10, and these protrusions and holes of the turntable 10 are connected to each other. The cleaner sheet 1 can also be fitted by fitting
1 can be prevented. In this case, a fitting hole may be formed in the cleaner sheet 11 in accordance with the position of the projection.

As shown in FIGS. 1 and 2, reference numeral 1 denotes an entrance gutter for guiding a pachinko ball 2 discharged from a pachinko game machine or the like to an inlet 3a of a middle cylinder 3 described later. Therefore, each pachinko ball 2 discharged from a pachinko gaming machine or the like flows down the entrance gutter 1 along the slope.

As shown in FIG. 1, a sensor 15 for detecting the number of pachinko balls 2 in the middle cylinder 3 is provided on the side of the entrance gutter 1 above the middle cylinder 3. When the number of pachinko balls 2 in the middle cylinder 3 reaches an appropriate number, the sensor 15 detects this and outputs a signal, and the signal is used to drive the motor 7 to rotate. Here, the moderate quantity is
It also means that the weight of the pachinko balls 2, that is, the pressing force (pressure) of the pachinko balls 2 against the cleaner sheet 11 mounted on the turntable 10 is appropriate. This appropriate quantity can be detected by detecting the level of the pachinko balls 2 in the middle cylinder 3.

Each pachinko ball 2 flowing down from the entrance gutter 1
Is introduced into the middle tube 3 from the inlet 3a of the middle tube 3 located below the one end 1a of the entrance gutter 1. This middle cylinder 3
Is for temporarily storing the pachinko balls 2. 1 and 2, the shape of the middle cylinder 3 is cylindrical, but the middle cylinder 3 has a pachinko ball 2 as described above.
Is temporarily stored, and any shape may be used as long as it has a shape for that purpose. That is, the shape of the middle cylinder 3 may be, for example, a cylinder, an elliptical cylinder, or a square cylinder, or a conical, elliptical cone, or pyramid.

The fixing structure of the middle cylinder 3 is optional. For example, the middle cylinder 3 is press-fitted or welded into a hole in the support plate to be integrated with the support plate, and the support plate is fixed between the side walls 5 and 5 of the frame 60 so that the middle cylinder 3 is positioned at a predetermined height. May be fixed. Lower end 3b of middle cylinder 3 and turntable 10
(Including the cleaner sheet 11 fixed on the turntable 10), there is a gap G1 through which one pachinko ball 2 can pass. This gap G1 is one end 3b of the middle cylinder 3
May be provided over the entire circumference or may be provided partially. When the material of the cleaner sheet 11 fixed on the turntable 10 is an elastic body (flexible body) such as felt, the gap G1 may be slightly smaller than the diameter of one pachinko ball 2. Good. Also, is the diameter of the middle cylinder 3 substantially the same as the width of the entrance gutter 1 or
Or larger. Therefore, as shown in FIGS. 1 and 2, the pachinko balls 2 flowing down along the slope of the entrance gutter 1 are sequentially introduced into the introduction port 3 a at the upper end of the middle cylinder 3.

As shown in FIG. 1, in the vicinity of the outer periphery of the middle cylinder 3, an outer cylinder 12 as an outflow restricting means is provided concentrically with the middle cylinder 3 and separated from the outer wall of the middle cylinder 3 by a width G3. ing. The outer cylinder 12 is connected to one end 3b of the middle cylinder 3 and the turntable 1
This is provided to restrict the pachinko balls 2 flowing out of the gap G1 with the zero from flowing out. 1 and 2, the outer cylinder 12 has a cylindrical shape. However, as described above, since the outer cylinder 12 is used to restrict the outflow of the pachinko balls 2, the outer cylinder 12 is used. Any shape can be used as long as it can restrict the outflow of water. That is, the shape of the outer cylinder 12 may be, for example, a cylinder, an elliptical cylinder, or a square cylinder, or may be a cone, an elliptical cone, or a pyramid.

The outer cylinder 12 is installed so as to have a slight gap G2 between the lower end 12b of the outer cylinder 12 and the turntable 10 (including the cleaner sheet 11 fixed on the turntable 10). I have. The gap G2 is provided so as to prevent the outer cylinder 12 from interfering with the rotation of the turntable 10. Therefore, the gap G2 may be smaller than the diameter of the pachinko ball 2. The outer cylinder 12 is held by a slide guide 13 described later.

As shown in FIG. 1, the outer cylinder 12 is provided with a slide guide 13 for moving the outer cylinder 12 in the vertical direction. The slide guide 13 is provided on the side wall 5.
The outer cylinder 12 is attached to the outer cylinder 12 to hold the outer cylinder 12 and to slide the outer cylinder 12 upward to release the pachinko balls 2 stored in the outer cylinder 12. The slide member 13c is integrally formed with the upper stopper 13a and the lower stopper 13b provided on the frame 60 side.

The slide member 13c can be slid vertically between the upper stopper 13a and the lower stopper 13b.
Therefore, the outer cylinder 12 can also be slid in the up and down direction together with the slide member 13c, and when the outer cylinder 12 is moved in the upper direction, the gap between the lower end 12b of the outer cylinder 12 and the upper surface of the turntable 10 is increased. Of the outer cylinder 12
The pachinko balls 2 stored inside can be released.

As described above, by moving the outer cylinder 12 upward, the pachinko balls 2 stored in the outer cylinder 12 are moved.
Can be released. Therefore, when the pachinko game hall is closed and all pachinko balls are collected, and when the cleaner sheet 11 mounted on the turntable 10 is to be replaced, the outer cylinder 12 is closed as shown in FIG. Is moved upward, the pachinko balls 2 stored in the outer cylinder 12 are discharged, and the cleaner sheet 11 is replaced if necessary. At this time, the released pachinko balls 2
The water flows down the collection gutter 16 provided below 0 along the slope, and is collected in the collection box 17. In addition, this collection is not limited to only when the cleaner sheet 11 is replaced,
When the pachinko ball cleaning is completed, when the pachinko ball 2 is collected due to a failure of the device, etc., it can be appropriately performed.

The lower stopper 13b is connected to the outer cylinder 12
Are provided on the turntable 10 at positions where a gap G2 can be provided. Therefore, when the pachinko ball 2 is normally cleaned, the slide member 13c is in contact with the lower stopper 13b, and the outer cylinder 12 is located on the turntable 10 so as to have a gap G2.

A notch 12c for discharging pachinko balls is formed in a part of the peripheral wall of the outer cylinder 12. The notch 12c is formed for discharging the pachinko balls 2 stored in the outer cylinder 12 and pushed up by the subsequent pachinko balls, and the pachinko balls 2 discharged from the discharge holes 12c are connected to the outlet gutters 14. Collected down the slope.

Next, the operation of the above embodiment will be described.
Now, for example, a pachinko ball 20 from a pachinko gaming machine or the like.
Is discharged and flows down the entrance gutter 1 along the slope to form the middle cylinder 3
Is introduced into the middle cylinder 3 from the introduction port 3a. When the number of pachinko balls 2 introduced into the middle cylinder 3 reaches an appropriate number, the sensor 15 detects this and the motor 7 is started by the detection signal.

By the rotation of the motor 7, the rotary disk 10 is rotated at an appropriate speed. At this time, the cleaner sheet 11 is also driven to rotate together with the turntable 10.
Therefore, the pachinko balls 2 that are in contact with the lowermost portion in the middle cylinder 3, that is, the pachinko balls 2 that are in contact with the cleaner sheet 11 mounted on the turntable 10, are cleaned by the weight of the pachinko balls 2 stored in the middle cylinder 3. It rolls on the cleaner sheet 11 while being pressed downward on the sheet 11. At this time, the dirt on the surface of the pachinko ball 2 is wiped off by the cleaner sheet 11, and the dirt on the surface of the pachinko ball 2 is cleaned.

Further, as described above, since the cleaner sheet 11 is also rotating together with the rotating disk 10, the tangential moment of the rotating disk 10 generated on the pachinko balls 2 in contact with the cleaner sheet 11, or Due to the centrifugal force, the pachinko balls 2 in contact with the cleaner sheet 11 are cleaned by the cleaner sheet 11 while moving to the outer peripheral side of the turntable 10. Therefore, the pachinko balls 2 in contact with the cleaner sheet 11 are
The cleaner sheet 11 is pressed downward by the weight of the pachinko balls 2 stored therein, and is moved to the outer peripheral side of the rotary disk 10 by the above-described circular motion of the rotary disk 10 while being moved. The sheet 11 is cleaned.

As described above, the pachinko ball 2 that has moved to the outer peripheral side of the turntable 10 has one end 3b of the middle cylinder 3 and the turntable 1
After passing through the gap G1 with the outer cylinder 12, the outflow to the outside is restricted by the peripheral wall of the outer cylinder 12. Therefore, the pachinko balls 2 that have passed through the gap G1 flow into the gap G3 from the outer wall of the middle cylinder 3 to the inner wall of the outer cylinder 12. Gap G of this pachinko ball 2
With the outflow into the pachinko balls 3, the pachinko balls 2 in the middle cylinder 3 sequentially move downward.

As described above, when the pachinko balls 2 in the middle cylinder 3 flow out into the gap G3 and the pachinko balls 2 are laid on the upper surface of the turntable 10 in the gap G3, the pachinko balls 2 enter the middle cylinder 3. Due to the downward pressure due to the weight of the stored pachinko balls 2, the effect of the circular motion of the rotating disk 10, and the restriction imposed by the inner wall of the outer cylinder 12, the pachinko balls 2 near the inner wall of the outer cylinder 12 are separated from the gap G3 As a result, the pachinko balls 2 are stored in layers in the gap G3. Specifically, among the pachinko balls 2 flowing into the gap G3, the pachinko balls 2 near the inner wall of the outer cylinder 12 are subjected to downward pressure due to the weight of the pachinko balls 2 stored in the middle cylinder 3. Due to the action of the circular motion of the rotating disk 10 and the restriction by the inner wall of the outer cylinder 12, the pachinko balls 2 in the middle cylinder 3 are pushed upward in the gap G3 by the amount of the pushed pachinko balls 2. It moves downward, sequentially passes through the gap G1, is similarly pushed upward in the gap G3, and is stored in the gap G3.

Therefore, the pachinko balls 2 that pass through the gap G1 and are in contact with the cleaner sheet 11 fixed on the turntable 10 also have the weight of the pachinko balls 2 stored in the gap G3 in the gap G3. As a result, the cleaner sheet 11 is pressed downward, and is moved toward the outer peripheral side of the rotating disk 10 by the action of the circular motion of the rotating disk 10 to be cleaned by the cleaner sheet 11. Then, it is pushed up by the action as described above. The pachinko ball 2 pushed upward in the gap G3 in this manner is discharged from the notch 12c formed in the outer cylinder 12. And this discharged pachinko ball 2
Are collected by flowing down the outlet gutter 14 along the slope.

Next, a method of replacing the cleaner sheet will be described. When replacing the cleaner sheet 11 fixed on the turntable 10 after the pachinko game hall is closed, first, the outer cylinder 12 is moved upward by sliding the slide member 13c upward. Then, the pachinko balls 2 stored in the outer cylinder 12 are released. At this time, if the outer cylinder 12 is slid upward while rotating the rotary disk 10 by the motor 7, the pachinko balls 2 in the outer cylinder 12 are smoothly discharged. The released pachinko balls 2 flow down the collection gutter 16 provided below the turntable 10 along the slope as shown in FIG.
Collected in 7. Thereafter, the motor 7 is stopped, and the cleaner sheet 11 attached to the turntable 10 is replaced.
Next, by sliding the slide member 13c downward, the outer cylinder 12 is moved downward, and the replacement of the cleaner sheet 11 is completed.

In order to replace the cleaner sheet, one end of a rotatable arm is attached to the side wall 5 and an outer cylinder 12 is attached to the other end of the arm. You may be able to approach. Conversely, the rotary disk 10 is slid or moved by an arm to move the rotary disk 10 away from the outer cylinder 12 or to approach the outer cylinder 12, thereby replacing the cleaner sheet. May be possible.

When the rotation speed of the rotary disk 10 increases,
Accordingly, the amount of the pachinko balls 2 flowing out also increases.
When the amount of the pachinko balls 2 flowing from the entrance gutter 1 is small, the number of the pachinko balls 2 in the middle cylinder 3 is also reduced.
In such a case, the pachinko balls 2 cannot be sufficiently cleaned because the pachinko balls 2 are not pressed against the cleaner sheet 11 fixed on the turntable 10 with an appropriate pressure. Therefore, the sensor 15 not only drives the motor 7 to rotate when the pachinko balls 2 introduced into the middle cylinder 3 reach an appropriate quantity, but also detects the pachinko balls 2 introduced into the middle cylinder 3. The number of rotations of the motor 7 is increased / decreased or the motor 7 is stopped according to the quantity to control the rotation speed, rotation or stop of the turntable 10. The rotation speed of the motor 7 can be controlled by, for example, an inverter.
In this way, since the pachinko balls 2 can be cleaned while keeping the amount of the pachinko balls 2 in the middle cylinder 3 constant, the pachinko balls 2 can be cleaned sufficiently and uniformly.

Only one sensor 15 can be provided to control the motor 7, or a plurality of sensors 15 can be used to control the motor 7. As an example of providing a plurality of sensors, for example, the sensor 1
5, the number of pachinko balls 2 introduced into the middle cylinder 3 may be detected by each of the above sensors, and the number of revolutions of the motor 7 may be controlled in accordance with the output of each sensor. In the example shown in FIG. 1, the sensor 15 is provided on the side of the entrance gutter 1 above the middle cylinder 3, but the sensor 15 may be provided anywhere as long as the above purpose can be achieved. For example, the sensor 15 may be provided in a tank that supplies the pachinko balls 2 to the pachinko ball cleaner, and the motor 7 may be rotationally driven by detecting that the pachinko balls are being supplied from the tank to the cleaner.

As described above, by controlling the motor 7 for driving the turntable 10 according to the output of the sensor, the middle cylinder 3
Since the number of the pachinko balls 2 can be kept constant and the pachinko balls 2 can be pressed against the cleaner sheet 11 with an appropriate pressure, the pachinko balls 2 can be optimally cleaned. Further, since the rotation of the turntable 10 more than necessary can be prevented, wear of the cleaner itself can be minimized, and power consumption can also be minimized. Further, when the outflow amount of the pachinko balls 2 is small, since the rotation speed of the turntable 10 is also low, the noise of the cleaner itself can be reduced.
When the outflow of the pachinko balls 2 is large, the rotating plate 10
The rotation speed is also high, but in this case, the operation rate of the pachinko game machine is high, and the noise inside the pachinko game hall is noisy.

Next, various modifications of the pachinko ball cleaner according to the present invention will be described. In the example shown in FIG. 3, the cleaner sheet 11 is also attached to the inner wall of the middle cylinder 3. According to this example, when the pachinko ball 2 moves downward in the middle cylinder 3, it is possible to remove dirt on the surface of the pachinko ball 2 that is in contact with the inner wall of the middle cylinder 3, and to further improve the cleaning power. Can be improved. Further, if the shape of the middle cylinder 3 is a cylinder, an elliptical cylinder, or a square cylinder, or a cone, an elliptical cone, or a pyramid, the cleaner mounted on the inner wall of the middle cylinder 3 is used. The displacement of the sheet 11 can be prevented. Further, as shown in FIG. 4, a flange 3c extending outward is formed at the lower end 3b of the middle cylinder 3, and a cleaner sheet 11 is attached to the lower surface of the flange 3c. Can be increased, and as a result, the cleaning power can be further improved. As a method of mounting the cleaner sheet 11 on the inner wall of the middle cylinder 3, for example, the cleaner sheet 11 is attached to the inner wall of a core material having the same shape as the inner wall of the middle cylinder 3, and the cleaner sheet is attached together with the core material. 11
May be mounted on the inner wall of the middle cylinder 3. If the middle cylinder 3 is formed so as to be divided into two along a plane including the central axis, the cleaner sheet 11 can be easily attached to the inner wall of the middle cylinder 3.

As shown in FIG. 3, a cleaner sheet 11 may be attached to the inner wall of the outer cylinder 12 as in the case of the middle cylinder 3. By doing so, the pachinko balls 2 that are in contact with the cleaner sheet 11 on the inner wall of the outer cylinder 12 are:
When pushed up in the gap G3, the cleaner sheet 1
1 removes surface contamination. Thus, the contact between the pachinko balls 2 and the cleaner sheet 11 can be increased, and the cleaning power can be further improved. Further, if the shape of the outer cylinder 12 is a cylinder, an elliptical cylinder, or a square cylinder, or a conical, elliptical cone, or pyramidal cylinder, the cleaner attached to the inner wall of the outer cylinder 12 is used. The displacement of the sheet 11 can be prevented. Since the cleaner sheet 11 is attached to both the inner wall of the middle cylinder 3 and the outer cylinder 12 as described above, the pachinko balls 2 introduced into the middle cylinder 3 do not come into contact with any other parts than the cleaner sheet 11. , Is efficiently cleaned. Further, in the conventional pachinko ball cleaner, the dirt of the pachinko ball 2 adheres to the cleaner main body. However, the embodiment shown in FIG. 3 has an advantage that the dirt does not adhere to the cleaner main body. There is.

Further, the cleaner sheet 11 is attached to the outer cylinder 1.
As for the method of mounting the inner sheet 2 on the inner wall, similarly to the middle cylinder 3, the cleaner sheet 11 may be attached to the inner wall of the core material having the same shape as the inner wall of the outer cylinder 12. If the outer cylinder 12 is formed so as to be divided into two along a plane including the central axis, the cleaner sheet 11 can be easily mounted on the inner wall of the outer cylinder 12.

As shown in FIG. 3 to FIG.
2 can also be formed in a two-stage configuration up and down. Upper outer cylinder 1
Reference numeral 22 denotes a detachable upper and lower part of the cleaner sheet 11 attached to the lower outer cylinder 121 by sliding the upper and lower parts along the upper surface of the lower outer cylinder 121. Is sandwiched between the upper end of the outer cylinder 121 and the lower end of the upper outer cylinder 122. This way,
The cleaner sheet 11 attached to the lower outer cylinder 12 can be securely fixed, and the displacement can be prevented. Further, if the cleaner sheet 11 is also attached to the upper outer cylinder 12, the cleaning power can be further improved.

In the example shown in FIGS. 1 to 5, the outer cylinder 12 as the outflow restricting means is located above the turntable 12, and a gap G2 is formed between the lower end of the outer cylinder 12 and the upper end of the turntable 12. However, as shown in FIG. 6, the rotating disk 10 is disposed inside the outer cylinder 12 so that the inner peripheral surface of the outer cylinder 12 is
A gap smaller than the diameter of the pachinko ball 2 may be formed between the pachinko ball 2 and the outer peripheral surface of the pachinko ball.

As shown in FIG. 8, an opening 12d may be formed in a part of the outer cylinder 12 so that the pachinko balls 2 can flow out to the outlet gutter 14 from the opening 12d. In this case, since the outer cylinder 12 does not have a function as a pachinko ball outflow restricting means, a shutter 81 as an outflow restricting means is provided at the outlet gutter 14 so as to be rotatable about a support shaft and can be opened and closed. The shutter 81 is opened or closed according to the number of the pachinko balls 2 in the middle cylinder 3 or the opening angle of the shutter 81 is changed, so that the pachinko balls 2 flowing to the outlet gutter 14 flow out. Limit the amount. It should be noted that the shutter 81 only needs to be able to limit the amount of the pachinko balls 2 flowing out to the outlet gutter 14, and may be appropriately changed. For example, the roller may be a sponge-like roller, a sprocket, an impeller, or the like. In addition, exit gutter 14
The outflow restriction may be performed by adjusting the inclination angle of.

The outlet gutter 14 can also be used as the collection gutter 16. In the example shown in FIG. 9, a guide member 20 for guiding the pachinko balls 2 discharged from the notch 12 c formed in a part of the peripheral wall of the outer cylinder 12 to the collection gutter 16 is provided. The collecting gutter 16 is for collecting the pachinko balls 2 remaining in the outer cylinder 12 as described above. In the example shown in FIG. 9, the guide member 20 removes the pachinko balls 2 from the notch 12 c of the outer cylinder 12. The discharged pachinko balls 2 that have been discharged are also guided onto the collection gutter 16. Therefore, the collecting gutter 16 also has a function as an outlet gutter for guiding the cleaned pachinko balls 2 to a predetermined position.

The turntable 10, the middle cylinder 3, and the outer cylinder 12 do not always need to be arranged horizontally and vertically. That is, the arrangement may be entirely inclined. Further, the middle cylinder 3 and the outer cylinder 1
The shape of 2 may be a net shape or a lattice shape.

[0056]

According to the first aspect of the present invention, at least one pachinko ball is provided between the rotating disk driven by the driving source, the cleaner sheet mounted on the rotating disk, and the cleaner sheet. The pachinko ball cleaner is formed by a middle cylinder that forms a gap through which the ball can pass, and that is disposed so as to face the rotating disk, and an outflow restricting means provided near the outer periphery of the middle cylinder to limit the outflow of the pachinko balls. With this configuration, the pachinko balls introduced into the middle cylinder are cleaned while being in contact with the cleaner sheet, so that the entire apparatus is compact and the pachinko ball transfer path can be shortened and efficient cleaning can be performed. Noise can also be relatively low. Further, since the cleaning is performed until the pachinko balls exceed the restriction by the outflow restriction means, the cleaning is efficiently and reliably performed.

According to the second aspect of the present invention, by providing a sensor for controlling the driving speed of the driving source in accordance with the amount of pachinko balls flowing into the middle cylinder, the amount of pachinko balls in the middle cylinder is provided. Is kept constant, so that pachinko balls can be uniformly and sufficiently cleaned.

If the exit gutter is provided at a position higher than the turntable, the pachinko balls are cleaned under a load required to push up the pachinko balls to the exit gutter, so that the efficiency is improved. There is an advantage that a proper cleaning is performed.

If the cleaner sheet is also attached to the inner surface of the middle cylinder as in the sixth aspect of the invention, the chance that the pachinko balls come into contact with the cleaner sheet increases, and the cleaning can be performed more efficiently. There is.

If the cleaner sheet is also mounted on the inner surface of the outer cylinder as in the invention of claim 8, the chance that the pachinko balls come into contact with the cleaner sheet increases, and the cleaning can be performed more efficiently. There is.

According to the ninth aspect of the present invention, when the cleaner sheet attached to the turntable is attached to a core material, the cleaner sheet can be easily removed and attached. If the cleaner sheet is stuck on both sides of the core material as in the described invention, when one of the cleaner sheets becomes dirty, it can be turned over and the other cleaner sheet can be used, which is very economical. .

According to the eleventh aspect of the present invention, if the rotating disk and the outer cylinder are separated from each other, a space between the lower end of the outer cylinder and the upper surface of the rotating disk is generated when the cleaner sheet is replaced. The pachinko balls stored in the outer cylinder can be discharged from the large gap, so that the cleaner sheet can be exchanged efficiently.
