The lifting device 20 includes a gas supply device (not shown) such as an air compressor, and by operating the gas supply device, gas is blown from a plurality of spray ports 97 toward the upstream bottom member 90 (arrows). See Y6c). That is, it can be said that the separation unit 36 is provided with a spray port 97 for blowing gas toward the game medium B and the abrasive material K that have flowed in from the lifting unit 31.

The separation unit 36 includes a vibration motor 98, which is an example of a vibration generation unit that generates vibration in the upstream bottom members 90, 90. When the vibration motor 98 operates, at least the upstream bottom members 90 and 90 of the separation unit 36 vibrate. The vibration motor 98 may be attached to the upstream bottom members 90, 90, or may be configured to transmit vibration to the upstream bottom members 90, 90 via a vibration transmission member (not shown). As described above, the bottom surface of the separation portion 36 is configured to be vibrable by the vibration motor 98. In an example of this embodiment, the vibration generated by the vibration motor 98 is transmitted to the downstream end portion of the upstream bottom members 90, 90 in the flow direction of the game medium B.

Then, the game medium B and the abrasive material K conveyed by the rotation of the screw member 33 flow into the inside of the separating portion 36 from the opening of the lifting aisle 32a of the lifting aisle member 32. Therefore, the separation unit 36 of the present embodiment constitutes an example of the inflow unit. The game medium B and the abrasive K that have flowed into the separation portion 36 are separated into left and right in the width direction Dw, and flow down onto the upstream bottom members 90, 90. In the upstream side bottom members 90, 90, the game medium B flows down to the left and right outside in the width direction Dw without falling from the plurality of separation holes H, and reaches the downstream side bottom members 92, 92. Then, the game medium B flows down on the downstream bottom members 92 and 92 and flows into the tanks 38 and 38 in the upper island (see arrow Y7a).

On the other hand, in the upstream bottom members 90, 90, the abrasive K falls from the separation hole H (indicated by arrow Y6a). The abrasive K that has fallen from the separation hole H and is recovered is cleaned by a cleaning unit (not shown). The washed abrasive K is conveyed to the upstream end of the screw member 33 and supplied to the lifting aisle 32a. That is, it is supplied again for polishing the game medium B. Here, the cleaning liquid used in the cleaning unit contains an antistatic agent (antistatic agent) as an additive. That is, the static electricity suppressant contained in the cleaning agent for cleaning the abrasive K is an example of the static electricity removing means.

Further, from each of the spray ports 97 of the spray nozzle 96, gas is sprayed onto the game medium B and the abrasive K that have flowed into the upstream bottom members 90 and 90. Further, the operation of the vibration motor 98 causes the upstream bottom members 90, 90 to vibrate. Therefore, the abrasive K mixed with the game medium B is shaken off downward, and it becomes easy to separate from the game medium B. Further, it is possible to easily separate the dirt removed from the game medium B by the rotation of the screw member 33.

Next, the shutter mechanism 80 included in the first delivery unit 69A and the second transmission unit 69B will be described. The shutter mechanism 80 provided in the sending units 69A and 69B has the same configuration. The shutter mechanism 80 is an example of a distribution control mechanism that controls the distribution of the game medium in the passage.

As shown in FIGS. 11 to 13, the shutter mechanism 80 includes a square box-shaped frame 81 extending in the vertical direction, a motor 83, and a shutter 85 which is an example of a distribution control member displaced by the motor 83. A guide portion 89 for guiding the displacement of the shutter 85 is provided. Hereinafter, the shutter mechanism 80 will be described in detail.

The frame 81 is fixed to the Shimawatari gutter 49B or the housing 39 by using fixing members (not shown) such as screws and bolts. A passage hole 81a that penetrates the frame 81 along the depth direction Dd is formed in the upper portion of the frame 81. That is, the upper portion of the frame 81 has a passage hole 81a, and constitutes a gate portion 82 through which the game medium B can pass through the passage hole 81a.

The gate portion 82 has a bottom plate 82a extending along the depth direction Dd, and side walls 82b and 82b erected at both ends of the bottom plate 82a in the width direction Dw, respectively. The side walls 82b and 82b face each other in the width direction Dw and form a side wall surface of the passage hole 81a. The bottom plate 82a forms the bottom surface of the passage hole 81a. That is, the bottom plate 82a forms a part of the bottom surface TSa of the island passage TS, which is an example of the passage. The game medium B flowing out from the supply port 38c of the tank 38 in the upper island can pass through the gate portion 82 when flowing down the island gutter 49B.

The bottom plate 82a is formed with a plurality of first insertion holes 82c that penetrate the bottom plate 82a along the height direction Dh. The plurality of first insertion holes 82c are arranged along the width direction Dw. There are eight first insertion holes 82c in the present embodiment, all of which are round holes. The diameter of the first insertion hole 82c is smaller than the diameter of the game ball Bp and smaller than the diameter of the game medal Bm. That is, the plurality of first insertion holes 82c have a size that the game medium B cannot pass through.

The shutter 85 has a square box-shaped base portion 86 extending along the width direction Dw, and a plurality of round bar-shaped shutter pins 87 erected so as to extend upward from the upper surface of the base portion 86. .. The plurality of shutter pins 87 are arranged along the width direction Dw (width direction of the island passage TS). In an example of this embodiment, there are ten plurality of shutter pins 87, all of which are rod-shaped portions (rod-shaped portions). The distance between the plurality of shutter pins 87 along the width direction Dw is narrower than the diameter of the game ball Bp and narrower than the diameter of the game medal Bm. The tip of the plurality of shutter pins 87 is thinner than that of the base end. The tips of the plurality of shutter pins 87 are all conical. That is, each of the plurality of shutter pins 87 has a sharp shape.

Of the plurality of shutter pins 87, the shutter pins 87 at both ends in the width direction Dw (hereinafter referred to as the first shutter pin 87) are compared with the other shutter pins 87 (hereinafter referred to as the second shutter pin 87). long. That is, when the base portion 86 is used as a reference, the tips of the shutter pins 87 at both ends are located higher than the tips of the other shutter pins 87. Further, the shutter pins 87 at both ends have a larger diameter (that is, thicker) than the other shutter pins 87. In the present embodiment, the shutter pins 87 at both ends serve as an example of the first rod-shaped portion, and the other shutter pins 87 serve as an example of the second rod-shaped portion.

As shown in FIG. 11, the shutter 85 can be displaced between the first position PA and the second position PB by the motor 83. The first position PA is a position where a part of the tip end side of the second shutter pin 87 projects from the first insertion hole 82c into the island passage TS, respectively, and restricts the distribution of the game medium B in the island passage TS. The second position PB is a position where the second shutter pin 87 does not protrude from the first insertion hole 82c into the island passage TS, respectively, and allows the game medium B to flow in the island passage TS. When the shutter 85 is in the first position PA, the second shutter pin 87 of 1 is inserted into each of the first insertion holes 82c. In a plan view, the first shutter pin 87 is located on the opposite side (outside) of the island passage TS with the side wall 82b interposed therebetween.

The diameter of the first insertion hole 82c is sufficiently larger than the diameter of the second shutter pin 87. Therefore, it is suppressed that the second shutter pin 87 comes into contact with the edge portion of the first insertion hole 82c as the shutter 85 is displaced. On the other hand, since the separation distance (clearance) between the second shutter pin 87 and the edge of the first insertion hole 82c becomes large, the abrasive material K, dust, dust, and the game medium B are scraped off from the portion. Foreign matter such as dirt may fall.

The guide portion 89 is provided below the gate portion 82 of the frame 81. The guide portion 89 extends from both ends of the first side wall 89a, which is a flat surface orthogonal to the depth direction Dd, and both ends of the first side wall 89a in the width direction Dw toward the side where the shutter 85 is arranged. It has side walls 89b and 89b. When the motor 83 operates, the shutter 85 moves the base portion 86 along the inner surfaces of the first side wall 89a and the second side wall 89b.

That is, the shutter 85 is displaced along the guide surface 89c, which is the inner surface of the side walls 89a and 89b on the base portion 86 side. The guide surface 89c extends along the direction intersecting the bottom surface TSa of the island passage TS. The guide unit 89 of the present embodiment does not have a ceiling. That is, the guide portion 89 is configured so that at least a part of the shutter 85 can pass through by opening the upper end portion 89d of the first side wall 89a and the second side wall 89b, which is the end on the island passage TS side. Will be done.

The shutter mechanism 80 of the present embodiment includes a protective plate 100 which is an example of a protective unit for protecting the components of the shutter mechanism 80 from foreign matter. The protective plate 100 is arranged between the bottom plate 82a and the upper end portion 89d of the guide portion 89 on the island passage TS side. The protective plate 100 is a square plate-shaped member extending along the width direction Dw. The protective plate 100 has a planar shape orthogonal to the height direction Dh.

A plurality of second insertion holes 101 are formed in the protective plate 100 so as to penetrate the protective plate 100 along the height direction Dh. The plurality of second insertion holes 101 are arranged along the width direction Dw. The plurality of second insertion holes 101 are round holes, and the diameter thereof is smaller than the diameter of any of the shutter pins 87. The diameter of the plurality of second insertion holes 101 is smaller than the diameter of the game ball Bp and smaller than the diameter of the game medal Bm.

The diameter of the plurality of second insertion holes 101 is smaller than the diameter of the plurality of first insertion holes 82c. A shutter pin 87 is inserted into each of the plurality of second insertion holes 101. Therefore, the gap between each shutter pin 87 and the edge portion of the second insertion hole 101 is smaller than the gap between the shutter pin 87 and the edge portion of the first insertion hole 82c. Therefore, even if a foreign matter falls from the first insertion hole 82c, the foreign matter falls below the protective plate 100 through the gap between the shutter pin 87 and the edge of the second insertion hole 101. Is suppressed.

Here, if a foreign substance that has fallen from the first insertion hole 82c enters between the guide surface 89c of the guide portion 89 and the base portion 86, it hinders the displacement of the base portion 86 and causes the shutter 85 to move. Displacement may not be performed properly. According to the present embodiment, the protective plate 100 prevents foreign matter from entering a certain portion of the base portion 86. Therefore, the interference of foreign matter can be suppressed. Further, the protective plate 100 is not fixed to other members, only the shutter pin 87 is inserted into the second insertion hole 101. Therefore, when the shutter 85 is displaced, the shutter pin 87 and the protective plate 100 are prevented from coming into contact with each other and hindering the displacement of the shutter 85. Further, since the first shutter pins 87 at both ends are longer than the second shutter pins 87, the protective plate 100 can be prevented from being easily removed even if the protective plate 100 sways along the height direction Dh.

Therefore, in the lifting device 20 capable of simultaneously polishing and lifting the game medium B, the outflow of the abrasive K can be suppressed.

(2) According to the present embodiment, since the spray port 97 is provided so as to extend along a direction intersecting the inclination direction of the bottom surface of the separation portion 36, uneven gas spraying is suppressed and the abrasive material is polished. It is suppressed that the separation of K is unevenly promoted.

Therefore, in the lifting device 20 capable of simultaneously polishing and lifting the game medium B, the outflow of the abrasive K can be suppressed.

(6) According to the present embodiment, since the bottom surface (upstream side bottom members 90, 90) through which the separation hole H opens vibrates, the abrasive K can be efficiently separated.
(7) According to the present embodiment, by exchanging the bottom member 90A for the game ball and the bottom member 90B for the game medal, any of the game ball Bp and the game medal Bm can be obtained from each game medium B. Abrasive material K can be separated. Therefore, the lifting device 20 can also be used in the plurality of types of game media B.

(10) According to the present embodiment, the second insertion hole 101 formed in the protective plate 100 is smaller than the first insertion hole 82c formed in the bottom plate 82a. That is, since the first insertion hole 82c is relatively large, interference between the first insertion hole 82c and the shutter 85 (distribution control member) is suppressed. Then, even if the foreign matter falls from the first insertion hole 82c, the protective plate 100 prevents the foreign matter from further falling into the guide portion 89. In particular, since the second insertion hole 101 is relatively small, the gap between the second insertion hole 101 and the shutter 85 (shutter pin 87) can also be made small. Therefore, the fall of foreign matter can be further suppressed. Therefore, the interference of foreign matter can be suppressed.

(14) According to the present embodiment, the shutter 85 is composed of a plurality of shutter pins 87 arranged along the width direction of the island passage TS. Therefore, the shutter 85 can be projected into the island passage TS and the island passage TS can be closed while easily scraping the game medium B in the island passage TS. Therefore, the load when closing the passage can be reduced.

(15) According to the present embodiment, since the tip end portion of the shutter pin 87 is thinner than the base end portion, when the shutter 85 enters the island passage TS, the game medium B in the passage is more easily used. It can be squeezed out.

(16) According to the present embodiment, the distance between the plurality of shutter pins 87 is narrower than either the diameter of the game ball Bp or the diameter of the game medal Bm. Therefore, the distribution of the game medium B can be regulated more reliably.

(18) According to the present embodiment, the intake port 31a of the game medium B is the upstream end portion (tip portion 35b of the screw 35) of the screw member 33 in the transport direction of the game medium B among the lifting aisle members 32. ) Is formed at a position separated from the downstream side. Therefore, depending on the shape of the game medium B, it is possible to prevent the game medium B from being caught in the upstream end of the screw member 33. Therefore, the lifting device 20 can also be used in the plurality of types of game media B. The entanglement depending on the shape of the game medium B occurs, for example, because the game medal Bm has a disk shape and is arranged so as to spread in the traveling direction of the tip portion 35b of the screw 35. Easy (see Figure 2).

(19) According to the present embodiment, since the upstream end portion (tip portion 35b of the screw 35) of the screw member 33 is a free end, the game medium B is likely to be caught depending on the shape of the game medium B. Become. However, since the intake port 31a of the game medium B is formed at a position separated from the upstream end of the screw member 33 to the downstream side, it is possible to suppress the entrainment of the game medium B.

(20) According to the present embodiment, the distance between the outer peripheral surface of the screw member 33 (screw 35) and the inner surface of the lifting passage 32a is narrower than the diameter of the game ball Bp and the thickness of the game medal Bm. It becomes difficult for both the game ball Bp and the game medal Bm to enter the gap. Therefore, the lifting device 20 can also be used in the game ball Bp and the game medal Bm.

(21) According to the present embodiment, since the pitch of the screw 35 (the portion extending spirally) of the screw member 33 is longer than the diameter of the game ball Bp and the diameter of the game medal Bm, these two types are used. The game medium B can be transported. Therefore, the lifting device 20 can also be used in the game ball Bp and the game medal Bm.
