Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game medium polishing machine for removing dirt adhering to game media such as pachinko balls and medals used in game machines such as pachinko machines and slot machines. .

[0002]

2. Description of the Related Art Generally, game media such as pachinko balls and medals are contaminated with dust, oils and fats when the media come into contact with each other or the player touches them with hands. These stains, especially stains that cannot be easily removed due to sticking to the surface of the game medium, are usually removed using a dedicated game medium polishing machine.

Conventionally, as a game medium polishing machine, for example, a self-cleaning dirt wiper is known. The dirt wiping machine is provided with a dirt wiping means such as a cloth that comes into contact with the surface of the game medium, and the dirt wiping means is used to wipe off dirt adhering to the surface of the game medium. In addition, there is also a game medium polishing machine that polishes off dirt on the surface of the game medium by polishing using a polishing material made of nylon or the like in the form of a minute cylinder called a pellet. In this polishing machine, the game medium to be washed and the pellets are put in the same container, and the container is rotated and stirred, so that the dirt adhered to the surface of the game medium is polished by the pellets and scraped off. There is. Furthermore, in addition to these, there is a cleaning machine for cleaning dirt using a cleaning liquid, for example, in the game medium polishing machine. In this washing machine, the game medium is immersed in a washing tank containing a washing liquid, and the dirt is removed by the action of the washing liquid.

[0004]

However, in the above-mentioned conventional game medium polishing machine, the following problems occur in removing dirt on the surface of the game medium. For example, in a self-cleaning dirt wiper,
Since the dirt is removed by the contact between the surface of the game medium and the dirt wiping means, the dirt cannot be surely removed depending on the attitude of the game medium, and the dirt adhered to the surface of the game medium cannot be sufficiently removed. There is a risk. Further, for example, in a polishing machine using pellets, since the pellets are used for removing dirt on the surface of the game medium, there is a possibility that a difficulty may occur in handling the pellet. Specifically, it is necessary to prevent that the pellets come out of the agitating container during the stirring or separation of the game medium and the pellets and cause the malfunction of the polishing machine. May be complicated.
Further, for example, in a washing machine using a washing liquid, a large number of game media to be washed are soaked in the washing tank and then these gaming media are taken out from the washing tank at the same time. It is difficult to synchronize with the game medium transporting operation, that is, it is difficult to automate the cleaning process, and as a result, a rapid cleaning process cannot be realized. Further, in this washing machine, since the dirt of the game medium is removed only by the action of the washing liquid, there is a possibility that the dirt adhered to the surface of the game medium cannot be sufficiently removed.

[0005] Therefore, the present invention may be a dirt affixed to the game medium surface, reliably and rapidly be able to remove it, yet it no game medium becomes complicated more than necessary structure for the The purpose is to provide a polishing machine .

As will be described later in detail, when the drum main body 21a rotates, the medals in the drum main body 21a are transferred to the medal mounting portion 21.
It is formed so that it can be placed on e '.

In the end face member 21b on the side where the discharge locking claw 21e is provided, there is formed an opening that is substantially concentric with the outer diameter thereof.
It is provided as a medal discharge port 21f. On the other hand, in the end surface member 21b arranged at the other end, as shown in FIG.
As shown in, a hole substantially concentric with the outer diameter is provided as a medal slot 21g. This input port 21
An end on the medal discharge side of the drum throw chute 13 can be fitted into g. Further, this end face member 21
As shown in FIG. 2A, a driven gear 21h having an axis centered on the drum body 21a as a rotation center is attached to b. However, the driven gear 21h may be attached to the end surface member 21h on the opposite side.

The cleaning drum 21 thus constructed is
As shown in FIGS. 1A to 1C, the drum support 22 supports the drum. The drum supporting portion 22 has four bearing rollers 22a and a supporting member 22b that supports the bearing rollers 22a. The four bearing rollers 22a are brought into contact with the peripheral edges of the end surface members 21b of the cleaning drum 21 to clean the bearing rollers 22a. The cleaning drum 21 is rotatably supported in a state where the axial direction of the drum 21 is substantially horizontal.
The drum support portion 22 is arranged in the cleaning tank 24. The cleaning tank 24 is formed of a substantially rectangular parallelepiped bottomed container for storing the cleaning liquid for medals.
Therefore, when the cleaning tank 24 stores a predetermined amount of cleaning liquid, the drum support portion 22 supports the cleaning drum 21 while the cleaning drum 21 is immersed in the cleaning liquid in the cleaning tank 24. The amount of immersion of the cleaning drum 21 at this time is such that at least the tip of the partition wall 21c located at the lowermost position is immersed in the cleaning liquid. The cleaning tank 24
The cleaning liquid stored therein may be any liquid suitable for cleaning medals, and examples thereof include water, hot water, a solution mixed with a detergent, and a solvent such as alcohol.

A drum drive unit 23 is provided near the cleaning drum 21 supported by the drum support unit 22. The drum drive unit 23 includes a drive gear 23a that meshes with the driven gear 21h of the cleaning drum 21, and a drive source 23b such as a motor that drives the drive gear 23a.
The cleaning drum 21 supported by the drum supporting portion 22 is driven in a predetermined direction to rotate in a predetermined direction.

The medal drying unit 30 for drying the medals from the medal cleaning unit 20 as described above is provided with a dehydration chute 31 which is formed so as to be fitted into the discharge port 21f of the cleaning drum 21, and the dehydration chute 31. A dehydrating roller portion 32 provided in the middle of the above, a drying drum 33 into which medals guided by the dehydrating chute 31 are inserted, and a heater 34 provided around the drying drum 33.

The dewatering chute 31 receives the medal in the cleaning drum 21 from its discharge port 21f and guides it to the drying drum 33 via the dewatering roller portion 32 while utilizing the natural drop. The dewatering roller unit 32 has a pair of dewatering rollers 32a formed of a water-absorbing member such as a sponge. When the medal from the medal cleaning unit 20 is guided by the dewatering chute 31, the dewatering roller unit 32 is dehydrated. By passing between the rollers 32a and absorbing the water adhering to the medal, the medal is dehydrated.

Like the cleaning drum 21, the drying drum 33 is formed in a cylindrical shape having a medal insertion port at one end and a medal ejection port at the other end, and a spiral partition wall in the cylinder. 33a is provided, is rotatably supported by the drum supporting portion 33b, and is rotated in a predetermined direction by the drum driving portion 33c. However, in this drying drum 33, the polishing brush 21d is not provided in the drum body, and the partition wall 33a is also formed of a metal member. Moreover, the drum body is formed of a mesh-shaped metal member so that the heat from the heater 34 can be easily transferred to the drying drum 33.

The heater 34 heats the drying drum 33 by using, for example, an electric heating element, and dries the medals in the drying drum 33 by the heat radiation. On the side facing the drying drum 33 across the heater 34,
It is preferable to provide a heat reflection plate 34a that reflects the heat from the heater 34.

The medal ejecting section 40 for ejecting the medal after the drying process by the medal drying section 30 receives the medal in the drying drum 33 from its ejection port and ejects the medal by gravity falling. In addition, it has an outlet chute formed by a sheet metal member or the like.

Next, using the medal grinder 1 configured as described above, a process for removing dirt adhering to medals,
That is, an operation example in the case of performing a medal cleaning process will be described. When the medal polishing machine 1 performs the medal cleaning process, first, the medals to be cleaned are loaded into the medal loading hopper 11. This insertion may be performed manually by a clerk at a game hall, or the medal insertion hopper 11
The medal transport conveyor or the like connected to may be automatically performed. When a medal is inserted into the medal insertion hopper 11,
The medals are sequentially guided to the cleaning drum 21 via the charging conveyor 12 and the drum charging chute 13, and are charged into the cleaning drum 21 through the charging port 21g.

At this time, the cleaning drum 21 is rotated by the driving of the drum driving section 23. However, even if the cleaning drum 21 rotates, the medals thrown into the cleaning drum 21 continue to be positioned on the lower side in the cleaning drum 21 due to the weight of the medal itself. Therefore, when the cleaning drum 21 rotates, the medals in the cleaning drum 21 are provided with the spiral partition wall 2 provided inside the cleaning drum 21.
Guided by 1c, the inside of the cleaning drum 21 is moved from the input port 21g side toward the discharge port 21f side to the region where the discharge locking claws 21e are provided.

By this movement, dirt on the surface of the medal inside the cleaning drum 21 is scraped off. This is because the medal in the cleaning drum 21 is in contact with the polishing brush 21d provided on the entire inner wall of the drum body 21a, and the discharge port 2
This is because it moves toward the 1f side. Moreover, since the medal in the cleaning drum 21 is supported so that the lower side of the cleaning drum 21 is immersed in the cleaning liquid in the cleaning tank 24,
It moves in the cleaning drum 21 while being immersed in the cleaning liquid. As a result, since the dirt is removed from the medal by the action of both the polishing brush 21d and the cleaning liquid, even so-called stubborn dirt adhered to the surface of the medal can be sufficiently removed. Become.

Further, in the cleaning drum 21, the partition wall 2
Since 1c is also formed in a brush shape, the cleaning drum 21
Even when the inner medals are guided to the partition wall 21c, the dirt on the surface of the medals is scraped off, and the dirt can be removed more effectively.

When the medal inserted from the insertion opening 21g is moved to the ejection opening 21f side, the rotation speed of the cleaning drum 21 is set so that the medal rises to the upper side in the cleaning drum 21 by centrifugal force, for example. Or
If a protrusion or the like for locking the medal is provided in the cleaning drum 21, the medal will be in a so-called dancing state in the cleaning drum 21, so that the dirt can be reliably removed from the front and back of the medal.

The medals from which the dirt has been removed are ejecting locking claws 2.
When reaching the area 1e, the medal is locked by the discharging locking claws 21e in that area and is lifted up. More specifically, the medals that have reached the area where the ejection locking claws 21e are provided have the ejection locking claws 2 in that area.
While being placed on the medal mount 21e ′ of 1e, the cleaning drum 21 is lifted to the upper side in the cleaning drum 21 as the cleaning drum 21 rotates, and then dropped from above the medal mount 21e ′. To do. At this time, since the dewatering chute 31 is fitted into the discharge port 21f of the cleaning drum 21, the medals dropped from the medal mounting portion 21e 'are thrown into the dewatering chute 31.

That is, the cleaning drum 21 from the charging port 21g
The medals thrown into the inside are thrown into the dewatering chute 31 after being subjected to a cleaning process for removing dirt, and thereby discharged from the discharge port 21f. At the time of discharging, the cleaning drum 21 temporarily raises the medal by using the discharging locking claws 21e in consideration of the fact that the cleaning liquid is stored in the cleaning tank 24.

The medal ejected from the ejection port 21f, that is, the medal inserted into the dewatering chute 31 is subjected to the dewatering process by the dewatering roller section 32, and then the drying drum 33.
It is thrown in. At this time, the drying drum 33 is rotated by the driving of the drum driving unit 33c. Further, the heater 34 heats the drying drum 33. Therefore, the medals thrown into the drying drum 33 are the same as in the case of the cleaning drum 21 described above.
It is guided by the partition wall 33a to move from the inlet side to the outlet side. Further, during the movement, the heater 34 heats the water, so that the water and the like remaining on the medal surface evaporate.

In this way, the drying process for the medals is performed on the drying drum 33. Also in this drying drum 33, if the medals are allowed to dance in the drying drum 33, the medals can be heated uniformly over the front and back of the medals, so that a quick and reliable drying process can be realized.

After that, the medals in the drying drum 33 are discharged from the discharge port to the outlet chute of the medal discharging section 40. At this time, in the drying drum 33, the cleaning drum 21
The operation of temporarily lifting the medal upward is not performed as in the case of. This is because it is not necessary to consider the cleaning liquid in the cleaning tank 24 in the drying drum 33.

The medals discharged to the exit chute are guided to the exit chute and discharged to the outside of the medal grinder 1 as washed medals. At this time, the ejection destination may be, for example, a storage container for storing a predetermined number of medals, a medal transport conveyor connected to another device (medal replenishing device, etc.), or the like.

As described above, the medal polisher 1 according to the present embodiment has the spiral partition wall 21 inside the cleaning drum 21.
c and a polishing brush 21d are provided so that the medals in the cleaning drum 21 can be moved while being guided by the partition wall 21c while being in contact with the polishing brush 21d. Therefore, if a cleaning process is performed by using the medal polishing machine 1, even dirt adhered to the surface of the medal can be sufficiently scraped off (polished) by the polishing brush 21d. Moreover, at that time, since it is not necessary to consider handling of pellets and the like unlike a conventional polishing machine, it is not necessary to provide a mechanism for preventing pellets from popping out, which complicates the apparatus configuration more than necessary. Nor. In addition, 21g input port
Since it is possible to sequentially insert medals into the medals and eject medals from the ejection port 21f, it becomes easy to correspond to the synchronization of the cleaning process and the medal transport operation, that is, the automation of the cleaning process, and as a result, the medal cleaning process is performed. You will be able to do it quickly. In other words, according to the medal grinder 1 of the present embodiment, even if the dirt adheres to the surface of the medal, it can be reliably and quickly removed, and therefore the device configuration becomes more complicated than necessary. It is possible to prevent it.

Further, the medal polishing machine 1 of the present embodiment
Since the partition wall 21c is also formed in the shape of a brush, even when the partition wall 21c guides the medals in the cleaning drum 21, the dirt on the surface of the medal can be scraped off.
It becomes possible to realize more effective removal of dirt.
However, the partition wall 21c may be formed of, for example, a plate-shaped metal member or resin member instead of the brush shape,
Needless to say, even in this case, the polishing brush 21d can surely and quickly remove the dirt.

Further, the medal polishing machine 1 of the present embodiment
Because the cleaning drum 21 is supported so as to be immersed in the cleaning liquid in the cleaning tank 24, the medals in the cleaning drum 21 are cleaned by the action of both the polishing brush 21d and the cleaning liquid. As a result, even so-called stubborn dirt adhered to the surface of the medal can be removed more sufficiently. However, the cleaning tank 24 does not necessarily have to be provided along with the cleaning drum 21. That is, even if the cleaning drum 21 is not submerged in the cleaning liquid in the cleaning tank 24, it is possible to sufficiently remove the stains on the medal surface only by the polishing brush 21d.
In this case, for example, if the polishing brush 21d is coated with an abrasive, the cleaning effect on the medal can be expected to be improved.

Further, the medal polishing machine 1 of the present embodiment
In addition to the medal cleaning unit 20 that performs the medal cleaning process using the cleaning drum 21 , the medal guiding unit 10, the medal drying unit 30, and the medal discharging unit 40 are provided. Therefore, the medal polisher 1 can easily cope with automatic insertion of medals to be cleaned and automatic ejection of medals after cleaning, and moreover, even if a cleaning liquid is used in the medal cleaning process, the medals are dried. Since the coins are ejected from the medal ejecting section 40 after the medals are ejected, a quick medal cleaning process can be realized.

In addition, the medal polisher 1 of this embodiment
Is configured to perform a drying process on a medal by using a drying drum 33 formed in a cylindrical shape and having a spiral partition wall 33a provided in the cylinder, and a heater 34 provided around the drying drum 33. ing. Therefore, in the medal polishing machine 1, it is possible, for example, to make the medal dance in the drying drum 33 during the medal drying process. As a result, in the medal drying unit 30,
Since it is possible to heat the front and back of the medal evenly, it is possible to realize a quick and reliable drying process. However, the medal drying unit 30 uses the drying drum 33.
It is also possible to use, for example, a conveyer for moving the medals along the heater 34, and to perform the drying process of the medals by using a transport conveyor or the like.

Further, the cleaning drum 21 used in the medal polishing machine 1 of the present embodiment is provided with a partition wall 21c and a polishing brush 21d in the drum body 21a. Therefore, if the cleaning process for the medals is performed using this cleaning drum 21, even if the dirt adheres to the surface of the medal, it can be surely and quickly removed, and therefore, the medals can be removed. It is possible to prevent the structure of the polishing machine 1 from becoming unnecessarily complicated.

[Second Embodiment] Next, a second embodiment of the medal grinder according to the present invention will be described. However, here, only the differences from the case of the above-described first embodiment will be described. 3A and 3B are schematic configuration diagrams showing an example of a main part of the medal polishing machine according to the present embodiment.

The medal polisher according to the present embodiment is different from that of the first embodiment in the medal cleaning unit.
As shown in FIGS. 3A and 3B, the medal cleaning unit includes a cleaning drum 21 ′ into which medals to be cleaned are loaded, a cleaning tank 24 for storing a cleaning liquid for medals, and the cleaning tank 24. The ultrasonic vibrating element 25 is provided.

The cleaning drum 21 'is the cleaning drum 2
In that the partition wall 21c 'disposed in 1'is not formed in a brush shape but is formed of, for example, a plate-shaped metal member or a resin member, and that the polishing brush is not arranged on the inner wall surface thereof, This is different from the case of the first embodiment. In addition,
The end face member 21b is provided with the inlet 21g, the outlet 21f, and the driven gear 21h, the outlet locking claw 21e is provided on the side of the outlet 21f, and the drum driving unit 23 is driven. It is similar to the case of the first embodiment in that it is supported by the drum support 22 so as to rotate.

The cleaning tank 24 is constructed in substantially the same manner as in the case of the first embodiment. In addition, this cleaning tank 24
As the cleaning liquid stored in the inside, it is more preferable to use a halogenated hydrocarbon solvent, a petroleum solvent, an alkaline degreasing agent, an emulsion cleaner, etc. in consideration of ultrasonic cleaning described later.

The ultrasonic vibration element 25 is for performing so-called ultrasonic cleaning by generating ultrasonic waves in the cleaning liquid stored in the cleaning tank 24.

Also in the medal cleaning section thus constructed, when a medal is inserted into the cleaning drum 21 'through the insertion slot 21g, the cleaning drum 21' will move to the drum driving section 2 '.
Since it is rotated by the drive of 3, the cleaning drum 2
In 1 ', the inserted medal is guided by the partition wall 21c' and moves from the insertion port 21g side toward the ejection port 21f side. At this time, the medals in the cleaning drum 21 ′ are immersed in the cleaning liquid stored in the cleaning tank 24 while the discharging locking claws 21
Move to the area where e is provided. Therefore, the medals thrown into the cleaning drum 21 'are cleaned by the cleaning liquid and its movement in the cleaning liquid.

Moreover, at this time, the ultrasonic vibration element 25
Generate ultrasonic waves in the cleaning liquid stored in the cleaning tank 24. As a result, the medal in the cleaning liquid vibrates slightly due to the cavitation phenomenon caused by the ultrasonic waves. That is, with respect to the medal in the cleaning liquid, the ultrasonic cleaning by the ultrasonic vibration element 25 and the cleaning liquid in the cleaning tank 24 can sufficiently remove even the so-called stubborn dirt adhered to the surface of the medal. .

After that, the medals in the cleaning drum 21 'are
Similar to the case described in the first embodiment, the toner is sequentially discharged from the discharge port to the outside of the cleaning drum.

As described above, the medal polisher according to the present embodiment has the spiral partition wall 21 inside the cleaning drum 21 ′.
c'is provided and its cleaning drum 21 '
Is supported so as to be immersed in the cleaning liquid in the cleaning tank 24,
By these, the medal inside the cleaning drum 21 'is moved while being immersed in the cleaning liquid while being guided by the partition wall 21c'. Therefore, if the medal polisher is used to perform a cleaning process on a medal, even dirt adhered to the surface of the medal can be cleaned by the cleaning liquid and the movement in the cleaning liquid. The cleaning power can be improved as compared with the case where the dirt is wiped off with a cloth wiping means such as a cloth or the case where the dirt is washed off simply by dipping the cleaning liquid. In particular, if the rotation speed of the cleaning drum 21 'is set and the protrusions that lock the medals are arranged so that the medals are allowed to dance in the cleaning drum 21', the cleaning power is surely improved. Will be things. Moreover, at that time, it is not necessary to consider the handling of pellets as in a conventional polishing machine using pellets, so that it is not necessary to provide a mechanism for preventing pellets from popping out, which complicates the apparatus configuration more than necessary. It doesn't get lost. Furthermore, since it is possible to sequentially insert medals into the insertion slot 21g and eject medals from the ejection slot 21f, it becomes easy to synchronize the cleaning process and the medal transport operation, that is, to automate the cleaning process. As a result, the medal cleaning process can be performed quickly. That is, even in the medal grinder of the present embodiment, even if the dirt adheres to the medal surface,
This can be removed reliably and quickly, and it is possible to prevent the device configuration from becoming unnecessarily complicated.

[0055] In addition, medal polishing machine of the present embodiment,
Since the ultrasonic vibrating element 25 is provided in the cleaning tank 24, the medals in the cleaning drum 21 'can be ultrasonically cleaned, and as a result, so-called stubborn stains adhere to the surface of the medal. Can be removed even more sufficiently.

In the above-described first and second embodiments, the case where the cleaning process for the medal is performed by one cleaning drum 21 and 21 'has been described as an example, but, for example, two or more cleaning drums. If cleaning processing is performed in parallel using 21, 21 ', improvement of medal processing capacity and speeding up of the processing can be expected. The same applies to the drying drum 33.

As described above, the play according to the present invention
In the game medium polishing machine , the game medium in the cleaning drum is moved while being guided by the partition wall, and at the same time, dirt adhering to the game medium is removed by using a polishing brush or a cleaning liquid in the cleaning tank. Therefore, even dirt adhering to the surface of the game medium can be sufficiently removed as compared with the conventional case. Moreover, at that time, it is not necessary to provide, for example, a mechanism for preventing pellets from popping out, and the device configuration is not unnecessarily complicated. Furthermore, since it is possible to sequentially insert the game medium into the cleaning drum and discharge the game medium from the cleaning drum, it is easy to correspond to the synchronization between the cleaning process and the game medium transport operation, that is, the automation of the cleaning process. As a result, the cleaning process of the game medium can be performed quickly. That is, according to the game medium polishing machine and the cleaning drum of the present invention, even if the dirt adheres to the surface of the game medium, it can be reliably and quickly removed.
Moreover, it is possible to prevent the device configuration from becoming unnecessarily complicated.
