BACKGROUND OF THE INVENTION
The present invention relates to a game medium purification device that removes dirt attached to game media such as medals and cards.
[0002]
[Prior art]
To a medal, which is a game medium such as a slot machine, dust generated by contact between medals or contact between a medal and a device, oil and fat by hand, and the like adhere. Conventionally, in order to remove such dirt, a dedicated dirt removing device has been used.
[0003]
As this dirt removing device, for example, there is a self-cleaning dirt wiper. This dirt wiping machine is provided with a drop path for dropping medals vertically on the medal transport path, and a dirt wiping means that comes in contact with the medal is projected on the inner wall of the drop path, and the medals falling on the fall path are wiped with dirt. Contact the means to wipe off the dirt on the medal surface.
In addition, the dirt removing device includes, for example, a grinder that scrapes off dirt on the medal surface by grinding. This polishing machine puts a micro cylindrical abrasive (made of pellets) made of nylon or the like and a medal together into a container and rotates it with a spiral stirrer to remove dirt fixed on the medal with the pellet. The medals were purified by scraping.
[0004]
[Problems to be solved by the invention]
However, the above-described self-cleaning dirt wiping machine can obtain only a momentary and small contact force when the medal falls due to its own weight and contacts the wiping means, and the dirt cannot be removed by a sufficient wiping force. . Further, the contact surface between the wiping means and the medal depends on the posture of the medal at the time of dropping, and the dirt on the front and back cannot be reliably removed.
On the other hand, the polishing machine using pellets requires a container for storing medals and pellets and a stirrer, and thus has a drawback that the apparatus becomes large and noise increases. In addition, the pellets enter the apparatus during the stirring and separation of the pellets and medals, causing a malfunction. In addition, since a large number of medals are put into a container at the same time for purification, the work cannot be performed in synchronization with the medal transport operation and cannot be incorporated into the medal transport path. Furthermore, since the apparatus is large and complicated, a great deal of labor is required to clean the apparatus once contaminated with maintenance.
The present invention has been made in view of the above situation, and an object of the present invention is to provide a game medium purification device that has a large purification capacity, can be incorporated into a medal transport path, and is easy to maintain.

DETAILED DESCRIPTION OF THE INVENTION
Preferred embodiments of a game medium purifying apparatus according to the present invention will be described below in detail with reference to the drawings.
1 is a schematic configuration diagram of a game medium purifying apparatus according to the present invention, FIG. 2 is a view taken along the line AA of FIG. 1, FIG. 3 is an enlarged view of a main part of FIG. 1, and FIG. FIG. 5 is a view taken along the line CC in FIG. 3, FIG. 6 is a view taken along the line DD in FIG. 3, and FIG. 7 is a conceptual view of the adhesive roller group shown in FIG.
[0014]
As shown in FIG. 1, a medal tank 5, an alignment mechanism 7, and a purification mechanism 9 are provided roughly in a device frame 3 of the game medium purification device 1. The medal tank 5 is provided with a medal slot 11 that opens to the outside of the device frame 3. The purification mechanism 9 is provided with a purification medal outlet 13 that opens to the outside of the device frame 3. That is, the game medium purifying apparatus 1 sends a plate-like game medium (hereinafter referred to as “medal”) 15 such as a medal and a card inserted into the medal slot 11 from the alignment mechanism 7 to the purifying mechanism 9, After being purified by the mechanism 9, the tokens are sequentially discharged from the medal discharge port 13.
[0015]
Therefore, the game medium purifying apparatus 1 may be provided alone, or incorporated in a medal transport path (not shown) so that the purifying operation can be performed in synchronization with the medal transport operation.
[0016]
The medal tank 5 is provided with an accommodating portion 17 for accommodating a plurality of medals 15 inserted from an upstream medal conveyance path (not shown). The alignment mechanism 7 described above is disposed at the bottom of the accommodating portion 17.
[0017]
The alignment mechanism 7 is provided with a transport unit 25 in which an endless belt 23 is stretched between a driven pulley 19 and a drive pulley 21. The transport unit 25 is configured such that the upper surface side of the peripheral circuit is moved in the direction of arrow a in FIG. The endless belt 23 is driven to rotate by a rotational force input from the drive motor 29 to the drive pulley 21 via a rotational force transmission means 27 such as a belt or a chain.
[0018]
An alignment roller 31 is disposed downstream of the upper surface side peripheral circuit of the endless belt 23 with an interval of approximately one medal from the endless belt 23. The alignment roller 31 is rotated such that the lower portion facing the endless belt 23 moves in the direction (arrow b direction) opposite to the movement direction (arrow a direction) of the upper surface side peripheral circuit of the endless belt 23. For example, the alignment roller 31 is rotationally driven by a rotational force transmitting means 33 stretched over the drive pulley 21.
[0019]
Therefore, when the medals 15 accommodated in the accommodating portion 17 are placed on the endless belt 23 and reach the alignment roller 31, the second or more stacked medals 15 are returned to the upstream side in the transport direction by the alignment roller 31. , The overlap is removed, and the sheets are aligned one by one and sent to the purification mechanism 9.
[0020]
As shown in FIG. 3, a medal passage 35 through which the medal 15 is moved in the direction of the arrow c is provided at the center in the vertical direction of the purification mechanism 9. Above the medal passage 35, a plurality (four in this embodiment) of adhesive rollers 37 that are in contact with the surface of the medal 15 and are driven to rotate are disposed. The adhesive roller 37 rotates in contact with the medal 15 to move the medal 15 in the direction of the arrow c. That is, the adhesive roller 37 also serves as a means for conveying the medal 15 in the purification mechanism 9. Accordingly, the adhesive roller 37 is rotated in the same direction as the passing direction of the medal 15 and at the same peripheral speed as the passing speed.
[0021]
In the adhesive roller 37, for example, the rotating shaft 39 is made of a core material such as metal, and an adhesive layer 41 made of adhesive silicon rubber or the like is provided on the outer periphery of the rotating shaft 39. The adhesive layer 41 is configured to adsorb dirt attached to the medal 15 by an adhesive force by contacting the medal 15. Further, the adhesive layer 41 is easily removed by washing the dirt adsorbed on the outer periphery with water, and the original adhesive force is developed again.
[0022]
Above the medal passage 35, as shown in FIG. 7, two lower adhesive rollers are sequentially arranged in a multi-stage with respect to one upper adhesive roller so that the adhesive roller 37 becomes the lowermost adhesive roller. An adhesive roller group 43 having a hierarchical structure by contacting is formed.
[0023]
In this embodiment, two intermediate layer adhesive rollers 47 are in contact with the uppermost adhesive roller 45, and the two lowermost adhesive rollers 37 are in contact with each of the intermediate layer adhesive rollers 47. Thus, an adhesive roller group 43 having a three-level hierarchical structure is configured.
[0024]
As shown in FIG. 5, the lowermost adhesive roller 37 is rotationally driven by a rotational force transmitting means 49 stretched around the shaft ends of the adjacent adhesive rollers 37. Further, as shown in FIG. 6, the adhesive roller 47 of the intermediate layer is also rotationally driven by the rotational force transmitting means 51 being stretched around the shaft ends of the adjacent adhesive rollers 47.
[0025]
Each of the adhesive rollers 37, 45, 47 of the adhesive roller group 43 is supported so as to be movable in a direction approaching and separating from the medal passage 35. Only the uppermost adhesive roller 45 is urged in a direction approaching the medal passage 35 by the urging force of the spring 53. As a result, the urging force of the uppermost adhesive roller 45 is transmitted to the lowermost adhesive roller 37 via the intermediate adhesive roller 47, and the lowermost adhesive roller 37 contacts the medal 15 with a predetermined pressing force. It is like that.
[0026]
The uppermost adhesive roller 45 is provided detachably from the purification mechanism 9. That is, the shaft end of the uppermost adhesive roller 45 is inserted into a U-shaped support groove 57 opened above the purification mechanism frame 55 and is rotatably held by a pressing arm 59 biased downward by a spring 53. Has been. Therefore, by releasing the locking of the spring 53 and the pressing arm 59 and moving the pressing arm 59 from the shaft end of the adhesive roller 45, the adhesive roller 45 can be easily detached from the purification mechanism frame 55. .
[0027]
In the adhesive roller group 43 configured in this way, the driving force is transmitted to all of the adhesive rollers by inputting the driving force only to the uppermost adhesive roller 45, for example.
[0028]
A guide plate 61 that closes the gap between the rollers is disposed between the adhesive rollers 37 in the lowermost layer. As a result, the medals 15 passing through the medal passage 35 are sequentially transferred to the adhesive roller 37 on the downstream side in the transport direction without dropping from the gap between the rollers.
[0029]
The adhesive force of the individual adhesive rollers of the adhesive roller group 43 configured in such a hierarchical structure is set larger in the upper layer than in the lower layer. That is, the [adhesive strength] is [adhesive strength of the uppermost adhesive roller 45]> [adhesive strength of the intermediate adhesive roller 47]> [adhesive strength of the lowermost adhesive roller 37].
[0030]
In the purification mechanism 9 according to the present embodiment, the adhesive roller group 43 configured as described above is arranged vertically symmetrically above and below the medal passage 35.
[0031]
Next, the operation of the game medium purifying apparatus 1 configured as described above will be described.
In this game medium purification device 1, when medals 15 are inserted into the medal tank 5, the inserted medals 15 are aligned one by one by the alignment mechanism 7 and sent to the purification mechanism 9.
[0032]
The medal 15 sent to the purification mechanism 9 is sandwiched by the lowermost adhesive roller 37 from the front and back directions, and is conveyed through the medal passage 35 in the direction of arrow c by the rotation of the adhesive roller 37. At this time, the dirt of the medal 15 is adsorbed by the adhesive force to the lowermost adhesive roller 37 that contacts the medal 15.
[0033]
Then, the dirt adsorbed on the lowermost adhesive roller 37 is sequentially adsorbed on the upper adhesive roller 47 having a large adhesive force. Accordingly, the dirt is collected on one uppermost adhesive roller 45 which finally becomes the apex of the hierarchical structure. That is, a plurality of large dirt adsorption areas are ensured, while one member for removing the adsorbed dirt can be provided. Thereby, a large purification capacity can be obtained and maintenance can be facilitated. Further, since the medal conveyance synchronized with the medal conveyance path is possible, the medal conveyance path can be incorporated.
[0034]
Further, when the medal 15 passes through the purification mechanism 9, the lowermost adhesive roller 37 of the adhesive roller group 43 comes into contact with the front and back surfaces of the medal 15, and dirt on the front and back surfaces is simultaneously passed by one pass of the medal 15. It can be removed. Since the medal 15 can be transported while being sandwiched between the lowermost adhesive rollers 37 disposed on the front and back sides of the medal 15, a device for transporting the medal 15 in the purification mechanism 9 is not necessary.
[0035]
Further, when the uppermost adhesive roller 45 is urged in the direction approaching the medal 15, all the adhesive rollers 47 and 37 of the adhesive roller group 43 are moved in a chained direction with respect to the medal 15 in a simple manner. With such a structure, a structure in which all the adhesive rollers 45, 47, 37 of the adhesive roller group 43 are urged toward the medal 15 side is obtained.
[0036]
In addition, since the uppermost adhesive roller 45 where the adsorbed dirt is collected can be removed, it is possible to clean the adhesive roller alone and to replace it with a cleaned one for easy maintenance. Become.
[0037]
In the above embodiment, the case where the game medium is the medal 15 has been described as an example. However, in the game medium purification apparatus according to the present invention, the game medium is a card such as a magnetic card or an IC card. Even if it exists, there exists an effect similar to the above-mentioned.
[0038]
Further, in the above-described embodiment, the case where there are four lowermost adhesive rollers 37 and has a three-stage hierarchical structure has been described as an example. However, the gaming medium purifying apparatus according to the present invention is the lowermost adhesive roller. Even if there are more rollers 37 and the hierarchical structure is three or more stages, the same effect as described above can be obtained.
[0039]
【The invention's effect】
As described above in detail, according to the game medium purifying apparatus of the present invention, the game medium purifying apparatus has an adhesive roller that contacts the game medium and is driven to rotate at the same peripheral speed as the passing speed of the game medium. In order to be the lowest-layer adhesive roller, two lower-layer adhesive rollers are sequentially brought into contact with one upper-layer adhesive roller in multiple stages to form a hierarchically-structured adhesive roller group, and individual adhesive roller groups Since the adhesive force of the adhesive roller is larger than that of the lower layer, the dirt adsorbed from the game medium by the adhesive force of the lowermost adhesive roller can be sequentially moved to the upper adhesive roller. Therefore, the dirt adsorbed by the many lowermost adhesive rollers can be collected on one uppermost adhesive roller. As a result, it is possible to provide a game medium purification device that has a large purification capacity, can be incorporated into the medal transport path, and is easy to maintain.
