  An embodiment of the lift polishing apparatus 10 will be described with reference to the drawings. FIG. 1 is a front view of the lift polishing apparatus 10 disposed on the gaming machine island 1, FIG. 2 is a side view of the lift polishing apparatus 10, and FIG. 3 is a functional block diagram of the humidifying means 11.

  As shown in FIGS. 1 to 3, the lifting and polishing apparatus 10 is used for a gaming machine island 1 in which a plurality of gaming machines are arranged, and includes a main body 2, an island tank 3, a humidifying means 11, a water supply means 20, and a water amount. The adjustment unit 25, the cylinder 30, the transfer unit 40, the separation unit 50, and the return passage 60 are provided. Here, the gaming machine may be referred to as a pachinko machine. In addition, game media used in gaming machines may be referred to as pachinko balls or out balls.

(Main unit 2)
The main body 2 includes a base 4 that is fixed at a predetermined position in the game arcade, and a column 5 that is erected on the base 4. An island tank 3 is provided on the upper side of the column 5. Separating means 50 and a motor 6 are provided at the upper end of the column 5.

  The game medium lifted together with the abrasive by the transfer means 40 is separated from the abrasive by the separation means 50, and supplied to each gaming machine through the island ridge (not shown). The game media used for each gaming machine is guided from the out ball collection basket 7 to the transfer means 40 through the out ball throwing bowl 8.

  The abrasive separated from the game medium by the separation means 50 is guided to the transfer means 40 by the return passage 60 and is transported together with the game medium by the transfer means 40. Thus, the abrasive is repeatedly used in the same manner as the game medium.

(Shimakami tank 3)
The island tank 3 temporarily stores game media when the game media fills the islands. An overflow passage (not shown) for guiding the game medium overflowing from the island tank 3 to the transfer means 40 is connected to the island tank 3.

(Humidifying means 11)
As shown in FIGS. 1 and 3, the humidifying unit 11 includes a humidity sensor 12, a control unit 13, and a water supply unit 20.

  The humidifying means 11 is configured not to allow dirt to adhere to the abrasive in the cylindrical body 30. The main cause of the dirt adhering to the abrasive is that the abrasive in the cylinder 30 is dry. As means for preventing dirt from adhering to the abrasive, for example, 1) means for moistening the abrasive with water before polishing the game medium; 2) moistening the abrasive with water when the game medium is being polished Means; 3) There is means for moistening the transfer means 40 with water. The means 1) and 2) may be referred to as means for directly moistening the abrasive with water. The means 3) may be referred to as means for indirectly moistening the abrasive with water.

  Hereinafter, means for moistening the abrasive with water before polishing the game medium will be described, means for moistening the abrasive with water when polishing the game medium, and means for moistening the transfer means 40 with water Will be described later.

  The humidifying means 11 wets the abrasive with water by continuously or intermittently supplying water to the abrasive before being transferred by the transfer means 40 based on the humidity in the cylinder 30. Thus, the inside of the cylindrical body 30 is humidified so that the humidity in the cylindrical body 30 is maintained within a predetermined range. Note that the humidifying means 11 may be configured in any way as long as the abrasive is moistened with water before the game medium is polished (immediately before the game medium is guided to the transfer means 40). If the humidifying means 11 is arranged at a position immediately before being guided to the transfer means 40, the abrasive can be effectively moistened with water. If the humidifying means 11 is arranged at a position some distance from the immediately preceding position, the humidifying means 11 can be arranged in an effective empty space.

  The predetermined range is preferably 50% to 60%, for example. The reason for this range is that when the humidity is less than 50%, the effect of preventing the dirt component from adhering to the abrasive becomes low, and the effect of suppressing the generation of static electricity becomes low. Further, when the humidity exceeds 60%, the dirt component tends to adhere to the game medium or the abrasive due to the wetness of the game medium or the abrasive, making it difficult to separate the dirt component.

  The humidity sensor 12 outputs a signal corresponding to the humidity in the cylindrical body 30. For example, the control unit 13 controls the amount of water supplied by the water supply unit 20 based on the signal output from the humidity sensor 12 so as to adjust the humidity in the cylinder 30.

  In addition, the humidity sensor 12 may be arrange | positioned in multiple places over the full length of the cylinder 30, for example at the start end part (lower end part), the intermediate part, and the termination | terminus part (upper end part), respectively. At this time, the control means 13 controls the water supply means 20 so as to finely adjust the humidity in the cylinder 30 based on the output signal of each humidity sensor 12.

(Water supply means 20)
As shown in FIG. 1, the water supply means 20 is disposed in the middle of the return passage 60. The water supply means 20 is configured to wet the abrasive passing through the return passage 60 with water. Any configuration may be used as long as the entire abrasive passing through the return passage 60 is wetted with water.

  As an example, there is a configuration in which the abrasive is moistened by spraying water on the abrasive in the return passage 60.

  FIG. 4 is a conceptual diagram of the water supply means. As shown in FIG. 4, the means for spraying water on the abrasive in the return passage 60 includes, for example, a nozzle 21, a pump 22, a tank (water tank) 23, and a water amount sensor 24. The nozzle 21 is disposed in the ceiling portion of the return passage 60. The pump 22 supplies the water in the tank 23 to the nozzle 21 at a high pressure. The water amount sensor 24 outputs a signal corresponding to the amount of water in the tank 23. Informing means for informing the amount of water in the tank 23 based on the output signal may be provided.

  In order to wet all of the polishing material passing through the return passage 60 with water, the water spraying range may be configured to be a predetermined region (full width and predetermined length) of the return passage 60.

  For example, what is necessary is just to comprise so that the range which sprays water may be extended to the predetermined area | region of the return channel | path 60. FIG. At this time, since the entire abrasive in the predetermined region can be moistened by a single spray, water may be sprayed intermittently.

  Further, for example, when the range in which water is sprayed is narrow with respect to the entire width of the return passage 60, the spraying direction may be changed along the width direction. Accordingly, water can be poured not only on the abrasive passing through the central portion of the return passage 60 but also on the abrasive passing through the end of the return passage 60.

  Furthermore, for example, when the range in which water is sprayed is narrower than the predetermined length of the return passage 60, the abrasive flows along the length direction in the range in which water is sprayed. , Can moisten the flowing abrasive.

  In the return passage 60, when the abrasives overlap vertically, the sprayed water enters the gaps between the abrasives, and the lower abrasive can be moistened.

  The sprayed water is preferably alkaline electrolyzed water having a pH value of 8-12. Alkaline electrolyzed water moistening the abrasive material penetrates into the gap between the dirt and the abrasive material due to its penetrating power, and the dirt is trapped and the dirt component does not adhere to the abrasive material (penetration, peeling) effect). In addition, the lipids in the soil decompose and become soap (soap effect). Furthermore, when the alkaline electrolyzed water touches the game medium, the game medium is sterilized (bactericidal effect). Further, the game medium is not rusted by alkaline electrolyzed water (rust prevention effect).

  In addition, since the effect will increase when the pH value of alkaline electrolyzed water is increased, alkaline electrolyzed water having a pH value corresponding to the degree of contamination may be used. In alkaline electrolyzed water having a pH value of less than 8, there is a tendency that the respective effects cannot be sufficiently obtained. In alkaline electrolyzed water having a pH value exceeding 12, although the respective effects are enhanced, it is necessary to add sodium peroxide and hydrogen peroxide, so that the production cost is further increased.

(Water volume adjusting means 25)
The water amount adjusting means 25 is arranged in the water supply means 20 in FIG. 1 or connected to the water supply means 20. The water amount adjusting means 25 is configured to adjust the amount of water according to the amount of abrasive flowing through the return passage 60, for example.

  As means for adjusting the amount of water, there are, for example, one configured to adjust the nozzle diameter, or one configured to adjust the pressure of water supplied to the nozzle by a pump. Adjustment of the nozzle diameter and water pressure may be performed manually or automatically.

  The quantity of game media used for the gaming machine island 1 can be predicted according to business hours and business days. Therefore, since the amount of abrasive can also be predicted, the nozzle diameter and the like may be manually adjusted according to business hours and business days.

  Further, a sensor (not shown) for detecting the amount of abrasive flowing in the return passage 60 may be provided, and the nozzle diameter and the like may be automatically adjusted based on a signal output from the sensor.

  The water supply unit 20 and the water amount adjustment unit 25 have been described above. Next, the lift polishing apparatus 10 incorporating these means will be described with reference to the drawings.

(Cylinder 30)
As shown in FIGS. 1 and 2, the cylinder 30 is erected on the gaming machine island 1. The cylindrical body 30 is provided between a lower end portion having a cylindrical shaft extending substantially horizontally, an upper end portion having a cylindrical shaft extending substantially upward, and a curved cylinder provided between the lower end portion and the upper end portion. And an intermediate portion having a shaft.

  An inflow port is provided at the lower end of the cylindrical body 30. A discharge port 31 is provided at the upper end of the cylindrical body 30. The inflow port of the cylindrical body 30 is connected with a basket through which the out ball flows down. As described above, a dirt component is attached to the out ball used in the gaming machine.

(Transfer means 40)
As shown in FIGS. 1 and 2, the transfer means 40 is disposed in the cylinder 30. The transfer means 40 is, for example, a spiral body that is arranged so as to follow the axis of the cylinder axis. The transfer means 40 is rotated by the motor 6.

  The transfer means 40 moves away from the out sphere, the abrasive, and the out sphere by transferring the abrasive and the out sphere moistened by the water supply means 20 upward in a mixed state inside the cylindrical body 30. The dirt component including the dirt is discharged from the discharge port 31 of the cylindrical body 30.

  When the transfer means 40 is rotated by the motor 6, the abrasive and the out ball are mixed and washed while rotating. At that time, the dirt component adhering to the out sphere is separated by the abrasive. The separated dirt component tends to adhere to the abrasive.

  Due to frictional heat generated when the abrasive and the out-sphere are mixed, the humidity inside the cylindrical body 30 decreases, and the moisture in the abrasive is lost until the abrasive is discharged from the discharge port 31. . However, even if the moisture is lost, the water supply means 20 wets the abrasive with water so that a minimum amount of moisture remains in the abrasive, so that the dirt component does not adhere to the abrasive. That is, the dirt component is discharged from the discharge port 31 in a state where it is separated from the out ball and the abrasive.

(Separation means 50)
Next, the separating means 50 will be described with reference to FIGS. FIG. 5 is a plan view of the lift polishing apparatus 10.

  The separation means 50 is configured to separate the discharged game medium, abrasive, and dirt component. The separating means 50 may be any means as long as it can separate the game medium, the abrasive, and the dirt component. The game medium, the abrasive, and the dirt component are separated based on their size and weight being different from each other.

  For example, as shown in FIGS. 1 and 5, the separating means 50 includes a scissors 51, a separating means 52, a collecting hose 55, a separating passage 53, and an abrasive stock 54. The spider child 51 is disposed so as to face the discharge port 31 of the cylindrical body 30. FIG. 1 shows a three-stage spear child 51.

  The scissors child 51 has a plurality of rails arranged with a gap of a predetermined width. The plurality of rails are configured to guide the game medium along the rails and to drop the abrasive and the dirt component from the gaps.

  The sorting means 52 is configured to separate the falling abrasive and dirt components. As an example of the sorting means 52, the dirt component and the abrasive are separated by collecting the dirt component based on the fact that the dirt component is extremely lighter than the abrasive. The dust collection of the dirt component is performed by sucking only the dirt component out of the falling abrasive and the dirt component, and is performed by blowing only the dirt component. FIG. 1 shows a separation means 52 of the type that sucks dirt components.

  As shown in FIG. 1, the abrasive and the dirt component separated from the game medium by the scissors 51 are guided to the inlet of the separation passage 53 (the upper end of the separation passage 53 in FIG. 1). A collecting hose 55 is disposed between the separation passage 53 and the separating means 52, and dirt components are sucked into the collecting hose 55, and only the abrasive is guided to the abrasive stock 54.

  The game medium separated from the abrasive and the dirt component is sent to the gaming machine and used for the game. The abrasive separated from the game medium and the dirt component is guided to the transfer means 40 and used for polishing the out sphere. The dirt component separated from the game medium and the abrasive is collected by the sorting means 52 so as not to be sent to the game machine or the cylinder 30.

(Return passage 60)
Next, the return passage 60 will be described with reference to FIGS.

  As shown in FIGS. 1 and 5, the return passage 60 is disposed so as to be inclined downward. The upper end opening of the return passage 60 communicates with the abrasive stock 54. The lower end opening of the return passage 60 is opened facing the transfer means 40. Note that the return passage 60 may include the separation passage 53 and the abrasive stock 54.

  A water supply means 20 is provided in the middle portion of the return passage 60. The return passage 60 is configured to guide the abrasive from the separating unit 50 to the transfer unit 40 via the water supply unit 20.

  By passing through the water supply means 20, it is possible to always wet the polishing material guided to the transfer means 40, and the wet balls can be polished with the wet polishing material.

  The return passage 60 guides the abrasive to the starting end of the transfer means 40. As a result, it is possible to polish the game medium with the abrasive material for a long section from the start end portion to the end portion of the transfer means 40, and to improve the polishing ability of the apparatus.

  Note that the position where the abrasive is guided is not limited to the starting end portion of the transfer means 40, but may be any other portion of the section from the start end portion to the end portion of the transfer means 40. Thereby, it is possible to increase the degree of freedom when designing the return passage 60, the water supply means 20, and the like.

  Further, the return passage 60 may guide the abrasive to the starting end portion of the transfer means 40 and the other portion (for example, the intermediate portion). Through the wet abrasive material not only at the beginning but also to other parts, penetration, peeling effect, soap effect, bactericidal effect, as described in the description of alkaline electrolyzed water used as sprayed water, and It becomes possible to enhance the rust prevention effect.

[Action]
Next, the operation of the lift polishing apparatus 10 will be described.

(Housing of abrasive)
In the lift polishing apparatus 10, the abrasive is repeatedly used for polishing. The abrasive is housed inside the lift polishing apparatus 10 including the abrasive stock 54.

(Abrasion of game media)
When the lift polishing apparatus 10 is started, the motor 6 rotates and is transferred in a state where the game medium and the abrasive are mixed in the cylindrical body 30 by the turning of the transfer means 40. When the game medium and the abrasive are mixed together, the dirt component does not adhere to the abrasive because the abrasive is moistened with water. Thereby, the abrasive is not soiled. Further, the game medium, the abrasive and the dirt component are discharged from the discharge port 31 of the cylindrical body 30 in a state where they are separated.

(Separation)
When the game medium, the abrasive and the dirt component are discharged from the discharge port 31 of the cylindrical body 30, the game medium and the abrasive and the dirt component are separated by the scissors 51. Further, the separating means 52 separates the abrasive and the dirt component. As a result, the separated game medium can be used for games, the abrasive can be used again for polishing, and the separated dirt component can be prevented from coming into contact with the game medium or the abrasive. Can be recovered.

(Moisten the abrasive with water)
The separated abrasive is guided to the transfer means 40 via the water supply means 20 by the return passage 60. As a result, the abrasive can be repeatedly used for polishing the game medium, and every time the abrasive is used for polishing, the water is supplied through the water supply means 20, so that the abrasive can be reliably moistened with water. it can. Thereby, even if it is repeatedly used for polishing, the abrasive is not contaminated, and the number of cleanings of the abrasive can be reduced.

(Game use and collection of game media)
Further, the game medium polished by the abrasive is separated from the dirt component, supplied to each gaming machine through a predetermined passage, and collected again from the gaming machine to the lifting and polishing apparatus 10. Since no dirt is attached to the medium and one game is attached to the game medium, it is avoided that the game is disturbed due to the dirt.

(Re-grinding of game media)
It is possible to polish the game medium by mixing the game medium collected from the gaming machine and the abrasive material, which is guided to the transfer means 40 by the return passage 60 and moistened with water, inside the cylindrical body 30. It becomes.

(Maintenance and inspection of water supply means 20 etc.)
The gaming machine island 1 is provided with an opening for maintenance and inspection of the transfer means 40, which is opened at the time of maintenance and inspection, and is normally closed by a lid member (not shown). The water supply means 20 is disposed in the vicinity of the starting end of the transfer means 40 (where the out ball and the abrasive are guided) (see FIG. 1).

  When the opening for maintenance and inspection is opened, the water supply means 20 can be seen through the opening, and when performing the maintenance and inspection of the transfer means 40, together with the maintenance and inspection of the water supply means 20 (nozzle 21, pump 22, tank 23, maintenance and inspection of the water amount sensor 24, etc.).

  As described above, according to the lift polishing apparatus 10 according to the above-described embodiment, dirt is not attached even if the abrasive is repeatedly used for polishing, and thus the number of cleaning operations of the abrasive can be reduced.

  In addition, before the abrasive is used for polishing, the abrasive can be surely wetted by passing through the water supply means 20. Further, the separation means 52 has an effect that dust components can be reliably collected.

(Other examples of water supply means 20)
Although the said embodiment demonstrated the water supply means 20 comprised so that an abrasive could be moistened by spraying water, it is not restricted to this.

  Next, another example of the water supply means 20 will be described with reference to FIG. The water supply means 20 is configured to wet the abrasive by dripping water onto the abrasive in the return passage 60.

  FIG. 6 is a conceptual diagram showing another example of the water supply means. As shown in FIG. 6, the water supply unit 20 includes a tank 23, a water amount sensor 24, a water amount adjustment unit 25, and a switch 26. The water amount adjusting means 25 adjusts the amount of water dripped. The switch 26 opens / closes the flow path to allow / prohibit the dripping of water.

  In order to wet all of the polishing material passing through the return passage 60 with water, the range in which the water is dropped is configured to be a predetermined region (full width and predetermined length) of the return passage 60. The use of alkaline electrolyzed water as the water to be used is the same as in the above embodiment in which water is sprayed.

  Furthermore, another example of the water supply means 20 will be described with reference to FIG. Another example of the water supply means 20 is configured to moisten the abrasive by putting the inside of the return passage 60 in a humidified state.

  FIG. 7 is a conceptual diagram showing another example of the water supply means 20. As shown in FIG. 7, the water supply means 20 includes a tank 23, a water amount sensor 24, a fan 27, and an ultrasonic generator 28. The water supply means 20 pulverizes water finely by ultrasonic vibration of the ultrasonic generator 28 and blows it out by a fan 27. The wall (bottom wall and side wall) of the return passage 60 is provided with a fine hole (not shown) through which the blown water droplets pass. In addition, as the water supply means 20, instead of the ultrasonic generator 28, a heater (not shown) may be provided, and water vapor generated by heating water may be blown out by the fan 27.

  The inside of the return passage 60 is humidified so that the entire abrasive material passing through the return passage 60 is moistened with water, the alkaline electrolyzed water is used as water when creating the humidified state, and the humidified state is further increased. Providing the water amount adjusting means to adjust is the same as in the above-described embodiment in which water is sprayed.

  In the above embodiment and modifications, the means for moistening the abrasive with water before polishing the game medium has been described.

  Next, an example of means for moistening the abrasive with water when the game medium is being polished will be described with reference to FIG.

  FIG. 8 is a conceptual diagram showing another example of the water supply means 20. As shown in FIG. 8, the water supply means 20 is configured to humidify the inside of the cylindrical body 30 by spraying water inside the cylindrical body 30. By spraying water inside the cylinder 30, the humidity inside the cylinder 30 can be increased and the abrasive in the cylinder 30 can be moistened with water. As a result, it is possible to prevent the dirt component from adhering to the abrasive.

  Further, when the humidity in the cylindrical body 30 is reduced due to frictional heat or the like when the game medium and the abrasive are mixed, static electricity is easily generated, and the abrasive and the dirt component are charged, and the abrasive is contaminated with the dirt component. However, by spraying water into the cylindrical body 30, a decrease in humidity in the cylindrical body 30 can be suppressed, and generation of static electricity can be suppressed.

  The water supply means 20 arrange | positioned at the start end part (lower end part) and intermediate part of the cylinder 30 is shown in FIG. A humidity sensor 12 that outputs a signal corresponding to the humidity in the cylinder 30 is disposed upstream of the water supply means 20. In FIG. 8, the water supply means 20 is arranged one by one at the start end and the middle part of the cylinder 30, but a plurality (for example, at a predetermined interval in the circumferential direction of the cylinder 30). It may be arranged.

  The use of alkaline electrolyzed water as the water to be sprayed and the provision of a water amount adjusting means for adjusting the amount of water to be sprayed are the same as in the above embodiment.

  Note that the water supply means 20 for moistening the abrasive with water when the game medium is being polished is not limited to spraying water, but water dropping means may be used.

  In the modification shown in FIG. 8, the humidifying means 11 has been described as means for directly moistening the abrasive with water when the game medium is being polished. However, the humidifying means 11 is means for indirectly moistening the abrasive with water. There may be.

  Next, as an example of means for indirectly moistening the abrasive with water, means for moistening the transfer means 40 with water will be described. For example, the transfer means 40 has water retention. Thereby, the transfer means 40 can be moistened with water. For example, in the transfer means 40, the surface (conveyance surface) that comes into contact with the abrasive during lifting has water retention. When the conveyance surface is moistened with water, the abrasive can be indirectly moistened with water by the abrasive coming into contact with the conveyance surface at the time of lifting. Moreover, by moistening the transfer means 40 with water, the inside of the cylinder 30 can be humidified, and it becomes difficult to generate static electricity.

  The use of alkaline electrolyzed water as water for moistening the transfer means 40 and the provision of a water amount adjusting means for adjusting the amount of water are the same as in the above embodiment.

  In the said embodiment, the water supply means 20 which wets an abrasive | polishing material with water before grinding | polishing a game medium was shown. Further, in the modification shown in FIG. 8, the water supply means 20 for moistening the abrasive with water when the game medium is being polished is shown, but the water supply means 20 may be combined. . As a result, the abrasive can be moistened with water in a more timely and more appropriate place.
