Description

  Embodiments of the present invention relate to a lifting and polishing apparatus used on a gaming machine island in which a plurality of gaming machines are arranged, and a gaming machine island including the same.

  The gaming machine island has a plurality of gaming machines equipped with gaming boards. On gaming machine islands, gaming machines are back to back and arranged horizontally along the gaming board.

  Gaming media such as pachinko balls and medals are supplied to the upper tank of each gaming machine through the island on the island of the gaming machine, and are launched into the gaming board of each gaming machine, stored in the lower tank from the outlet, and stored in the lower tank. It is collected for use again through the lower tub. As game media is used in gaming machines, components containing dirt such as dust, rust, and fat adhere to the game media. This component may be referred to as “dirt component”, “dirt”, or “component”.

  The place where the game medium passes due to dirt adhering to the game medium, that is, the island top, the upper tank, the game board, the lower tank, the lower bowl, etc., may become dirty and hinder the game. Therefore, it is necessary to remove dirt from the game medium.

  One method of polishing the game medium is a method in which the game medium in the cylinder and the abrasive are transferred (lifted) in a mixed state by rotating the spiral inside the cylinder (see FIG. For example, Patent Document 1).

  When the game medium in the cylinder and the abrasive are transported in a mixed state, the game medium and the abrasive come into contact with each other. At this time, the abrasive material scrapes dirt from the game medium. As a result, the dirt is removed from the game medium, and the game medium is polished.

JP 2006-312085 A

The transported game medium is separated from the abrasive and dirt components by a plurality of holes provided in the peripheral wall of the upper end portion of the cylinder and a scissors-like passage provided on both sides of the cylinder, and is stored in the storage tank. Supplied. Then, the separated game medium is supplied from the storage tank to the island top. On the other hand, the abrasives separated by the plurality of holes and the scissors-shaped passages are collected, for example, at the entrance of a collection path provided on one side of both sides of the cylinder and returned to the lower part of the cylinder. The returned abrasive is again used for polishing the game medium. That is, it is necessary to circulate the abrasive.
The abrasive separated by the plurality of holes and the saddle-like passages falls on both sides of the cylinder. It is relatively easy to guide the abrasive that has fallen to one side of both sides of the cylindrical body to the entrance of the collection path provided on the same side. However, in order to guide the abrasive that has fallen to the other side of the cylinder to the entrance of the collection path provided on the opposite side, the abrasive is passed through the gap on the front side and / or the rear side of the cylinder. It is necessary and the gap is narrow due to the narrowing of the installation space of the lifting and polishing apparatus and the downsizing of the lifting and polishing apparatus, so that the abrasive is clogged, and the abrasive can be circulated without retaining it. There was a problem that became difficult.

  An embodiment of the present invention solves the above-described problem and aims to easily circulate an abrasive.

  In order to solve the above-mentioned problem, the invention according to claim 1 has an upright cylinder, mixes a game medium with an abrasive, and lifts the cylinder from the lower end to the upper end, In the lifting and polishing apparatus configured to separate the transported game medium and the abrasive and return the separated abrasive to the lower end of the cylinder, the cylinder is provided at the upper end of the cylinder and the cylinder Separating means for separating and dropping the abrasive while passing the transported game medium and abrasive over a predetermined range in a direction away from the cylinder from both sides of the body, and from the cylinder to the cylinder A first collection path for collecting the abrasive that falls in a first range between a position separated by a predetermined length on one side of the body and the first on one side of the cylinder; A second collection path for collecting abrasives falling in a second range up to the predetermined range further away from the range Receives the abrasive material from the first and the second collection path from the one side, a passage mechanism for sending to the other side of both sides of each separately the cylindrical body, characterized by having a.

The gaming machine island 1 includes a frame 100 constructed on the floor of the gaming hall, a plurality of gaming machines 200, and a gaming medium circulation mechanism. A large number of gaming machines 200 are back-to-back, arranged side by side along the front and back surfaces, and housed in the frame 100. Hereinafter, the gaming machine 200 will be described as a pachinko machine, and the gaming medium will be described as a gaming ball (pachinko ball). Here, a direction in which the gaming machines 200 are arranged side by side is referred to as a “longitudinal direction”. The horizontal direction orthogonal to the longitudinal direction is referred to as the “short direction”. A direction perpendicular to both the longitudinal direction and the short direction is referred to as a “height direction”.

  The frame 100 includes, from above, a curtain board 101, a storage frame 102, a ceiling board (also referred to as a top board) 103, a waist board 104, and a baseboard (not shown). A gaming machine 200 is stored in the storage frame 102. A gaming machine 200 is placed on the board 103. Here, the space between the front-side curtain plate 101 and the back-side curtain plate 101 of the gaming machine island 1 may be referred to as an upper space. In addition, a space below the collar plate 103 and between the front waist plate 104 and the back waist plate 104 may be referred to as a lower space.

  The game medium circulation mechanism includes a lower tank 7, an out ball throwing cage 8, an out ball guiding rod 8 a, an island top rod 9, and a lifting and polishing device 10.

  The lower tank 7 is provided in the lower space. A game ball (referred to as “out ball”) used in the gaming machine 200 is thrown into the lower tank 7 through the out ball throwing bar 8. The out ball thrown into the lower tank 7 is transferred to the center of the gaming machine island 1 through the out ball guide bar 8a. The island top 9 is provided in the upper space.

  The lift polishing apparatus 10 is configured to polish and lift the game ball by lifting the game ball and the abrasive while stirring. The abrasive is a resin particle, has a porous structure, and can remove dirt from the game ball by stirring with the game ball.

  FIG. 2 is a perspective view of the lift polishing apparatus 10. FIG. 3 is a front view of the lift polishing apparatus 10. As shown in FIGS. 1 to 3, the lifting and polishing apparatus 10 includes a main body 2 and an island tank 3, and is provided at the center of the gaming machine island 1. The lift polishing apparatus 10 lifts the game ball transferred to the center of the gaming machine island 1 while polishing it, and stores the lifted game ball in the island tank 3. The game balls stored in the island tank 3 flow down to the respective gaming machines 200 through the island cage 9. As described above, the game medium circulation mechanism is configured to be recyclable by circulating the game ball inside the gaming machine island 1.

  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. The island tank 3 is provided on the upper part of the support column 5. An abrasive stock 54 described later has the function of the support 5.

  The transfer means 40 includes a helical screw member 41 (only an axis is shown in FIG. 3) inserted into the cylindrical body 30 and a motor 42 that rotates the screw member 41 in the cylindrical body 30. . By rotating the screw member 41 in a predetermined direction, the game ball and the abrasive are transferred while being agitated from the junction 31 toward the upper side of the island tank 3, and during this time, the game ball is polished by the abrasive. The transferred game balls and abrasives flow out from the upper end of the cylindrical body 30 to the separating means.

<Lifting polishing apparatus 10>
The abrasives separated by the separating means (hereinafter, unless otherwise specified, may include “dirt components”) fall on both sides of the cylindrical body 30. As described in the section “Problems to be Solved by the Invention”, it is comparative to guide the abrasive that has fallen to one side of both sides of the cylinder to a funnel body 521 (described later) provided on the same side. Simple. However, when the abrasive that has fallen on the other side of the cylindrical body 30 is caused to flow straight down to the funnel body 521 provided on the opposite side by the weight of the abrasive, a passage for causing the abrasive to flow down is in the middle. Since the cylindrical body 30 is included, the road width when passing through the side of the cylindrical body 30 is the narrowest (hereinafter referred to as “narrow part”). Therefore, the abrasive concentrates on the narrow portion (described later), and the abrasive is easily clogged or retained. On the other hand, it is possible to prevent clogging and stagnation of the abrasive in the narrow portion by collecting means for collecting the dropped abrasive in a plurality of regions and separately passing the narrow portion.

Next, the lift polishing apparatus 10 provided with the above means will be described.
The lift polishing apparatus 10 is used for a gaming machine island 1 in which a plurality of gaming machines 200 are arranged. The lift polishing apparatus 10 includes a cylindrical body 30, a transfer means 40, a separation means 50a, an additional separation means 50b, first collection paths 5201A and 5201B, second collection paths 5202A and 5202B, and a funnel. A body 521, a standing wall 522, a passage mechanism 523, a recovery pipe 530, an abrasive stock 54, a return passage 60, and a dust collecting means 62 are provided. The funnel 521 may be referred to as a “collection path”.

(Cylinder 30)
The cylinder 30 is erected on the gaming machine island 1. The cylindrical body 30 includes a lower portion 30b having a cylindrical shaft extending in the longitudinal direction of the gaming machine island 1, an upper portion 30c having a cylindrical shaft extending in the height direction of the gaming machine island 1, and a lower portion and an upper portion. And an intermediate portion 30d having a cylindrical axis curved in between. With such a configuration, the cylindrical body 30 is erected in a J shape on the gaming machine island 1.

  A joining portion 31 is provided in the lower portion 30 b of the cylindrical body 30. In the merging portion 31, the game medium (out sphere) from the out ball guiding rod 8 a and the abrasive from the return passage 60 merge and flow into the cylindrical body 30.

(Transfer means 40)
The transfer means 40 transfers the game medium and the abrasive material merged in the merge portion 31 upward in a state of being mixed inside the cylindrical body 30, and is separated from the game medium, the abrasive material, and the game medium during the transfer. The dirt component including dirt is discharged from the upper part of the cylinder 30. The transfer means 40 includes a screw member 41 and a motor 42. The screw member 41 is a spiral member inserted into the cylindrical body 30. The motor 42 rotates the screw member 41 inside the cylindrical body 30.

  When the motor 42 rotates the screw member 41 in a predetermined direction, the game medium and the abrasive are transferred (lifted) from the lower part to the upper part of the cylindrical body 30 while being agitated. During this transfer, the game medium is polished by the abrasive. The transferred game medium, abrasive and dirt components are discharged from the upper part of the cylinder 30 and flow out to the separating means 50a.

[Separation means 50a]
FIG. 4 is a front view showing the separating means 50a, and FIG. 5 is a perspective view of the main part of the lift polishing apparatus. As shown in FIGS. 4 and 5, the separating means 50 a performs polishing while passing the transported game medium and the abrasive over a predetermined range from both sides of the cylinder 30 in a direction away from the cylinder 30. Separate and drop the material.

  The reason why the separating means 50a is arranged on both sides of the cylindrical body 30 is to send game media to the plurality of gaming machines 200 in the gaming machine island 1 arranged in the directions on both sides of the cylindrical body 30. This is because the depth of the lifting and polishing apparatus 10 becomes thicker and hinders downsizing.

  “Both sides” refers to the direction in which the gaming machines 200 are arranged on the gaming machine island 1 with the cylindrical body 30 as the center, and the directions indicated by “D1” and “D2” in FIG. Moreover, the horizontal direction orthogonal to the direction of D1 and D2 is called the front and back. Here, "both sides of the cylinder" means both sides when the axis of the cylinder is the center, even if the game medium or abrasive is discharged from the front or rear of the cylinder, It is assumed that it is discharged from either “one of both sides of the cylinder” or “the other of both sides of the cylinder”.

(Separate discharge cylinder 30a)
The separation unit 50 a includes a separation discharge cylinder 30 a, a dropping unit 500, and a limiting unit 501. A separation discharge cylinder 30 a is provided at the upper end of the cylinder 30. The separation discharge cylinder 30a has a long hole h1 formed in a wall thereof. The long hole h1 has a gap narrower than the diameter of the game medium and wider than the diameter of the abrasive, and the fed abrasive is dropped through this gap.

  Since the gap is provided on the entire circumference of the separation discharge cylinder 30a, the direction in which the abrasive is discharged from the cylinder 30 is one on both sides of the cylinder 30 (D1 direction) and the other on both sides of the cylinder 30 (D2 direction). ), In all directions including the front of the cylinder 30 and the rear of the cylinder 30. However, as described above, even when the abrasive is discharged from the front or rear of the cylinder 30, it is discharged from one (D1 direction) or the other (D2 direction) of the cylinder 30. Is done.

  The upper end portion of the cylindrical body 30 is surrounded from four sides by standing walls 522 on one side (in the direction of D1), the other side (in the direction of D2), the front side, and the rear side. An upper opening 522a is provided in one standing wall 522 and the other standing wall 522. Outlet passages 32 are arranged in the gap between the front and rear standing walls 522 on both sides of the upper end opening of the cylindrical body 30. The leading end of the lead-out path 32 is passed through the upper opening 522a. The lead-out path 32 receives the game medium and the abrasive from the upper end port of the cylindrical body 30, and guides it to both sides (directions D1 and D2) of the cylindrical body 30.

(Drop means 500)
The dropping means 500 is discharged from both sides of the cylinder 30 through the lead-out path 32, and separates the game medium and the abrasive by dropping the abrasive while guiding the game medium away from the cylinder 30.

  The dropping means 500 includes a plurality of rails, and is configured in the shape of a spider. The plurality of rails are arranged with a gap having a predetermined width. This predetermined width is narrower than the width of the game medium and wider than the width of the abrasive. Further, the plurality of rails are provided to be inclined from a position where the game medium discharged from both sides of the cylindrical body 30 can be received to a position above the additional separation means 50b. Thereby, the game medium flows on the plurality of rails along the longitudinal direction thereof, and the abrasive material falls through the gaps.

(Limiting means 501)
The limiting unit 501 limits the movement of the game medium guided by the dropping unit 500. For example, the game medium may flow down while moving so as to jump on the dropping means 500. When the game medium performs such a movement, the game medium may pass through the dropping means 500 before the abrasive is separated. The restricting means 501 restricts such movement of the game medium.

  The limiting means 501 includes a sheet material. FIG. 6 is a front view showing a sheet material. For the sheet material, a flexible material such as rubber is used. The sheet material is provided so as to have a surface that intersects the longitudinal direction of the plurality of rails. The sheet material has a slit S in the lower part on the rail side. The width of the slit may be provided in accordance with the gap of the rail. Thereby, the motion of the game medium for each gap of the rail can be individually restricted.

  A mounting hole h2 is provided in the sheet material. By inserting a fastener such as a screw into the attachment hole h2, the sheet material is suspended above the dropping means 500. The length L of the sheet material is at least a dimension in contact with the rail. The sheet material is provided such that the lower part (slit S side) is in contact with the rail and is bent toward the downstream side of the dropping means 500.

  The restricting means 501 includes a plurality of sheet materials in the longitudinal direction of the plurality of rails (see FIG. 4). Thereby, the space above the dropping means 500, that is, the space in which the game medium flows is defined into a plurality of spaces. For example, when the game medium discharged from the upper part of the cylinder 30 flows out onto the dropping means 500 vigorously, the flow of the game medium is limited by the sheet material. The game medium flows down on the rail so as to push the sheet material while the flow momentum is limited.

  By the dropping means 500 and the restricting means 501, the game medium flows on the rail while being stroked by the sheet material. Further, by providing the restricting means 501, it is possible to prevent the game medium from flowing vigorously on the dropping means 500. The game medium flows on the dropping means 500 while the movement is restricted by the restriction means 501. Thereby, the game medium is guided to the separating means 50b while being separated from the abrasive. Further, when the game medium flows down on the rail so as to push the sheet material away, the abrasive is scooped from the game medium by the sheet material and falls through the gap of the rail. The game medium that has passed through the dropping means 500 is guided to the separating means 50b.

(First range R1, second range R2, standing wall 522)
FIG. 7A is a conceptual plan view of the first range R1, which is a range in which the abrasive separated from the separation discharge cylinder 30a mainly falls, and FIG. 7B is an abrasive separated from the dropping means 500. It is a notional top view when seeing from the upper side the 2nd range R2 which is the range which falls mainly.

  As shown in FIGS. 4, 7A, and 7B, the separation / discharge cylinder 30a and the dropping means 500 cause the game medium and the abrasive to move away from the cylinder 30 from one side on both sides of the cylinder 30 (direction D1). The abrasive is separated and dropped while being passed over a predetermined range RA.

One standing wall 522 is provided at a position that is a predetermined length away from one side on both sides of the cylindrical body 30 in a direction away from the cylindrical body 30 (direction D1). The dropping means 500 is connected to the leading end portion of the lead-out path 32 that passes through the upper opening 522a of the one standing wall 522 and exits from the one standing wall 522 to the outside (the direction side of D1).
Due to one standing wall 522, the first range R1 between the first range R1 between the one side on both sides of the cylindrical body 30 and a position separated by a predetermined length in the direction away from the cylindrical body 30 (direction D1), Is divided into a second range R2 from the range R1 to a predetermined range RA further away in one direction.

The standing wall 522 is provided because the abrasive material separated from the separation / discharge cylinder 30a drops in the first range R1 in principle. Even if the abrasive material separated from the separation / discharge cylinder 30a jumps to one side (in the direction of D1), it falls into only the first range R1 by coming into contact with one of the standing walls 522. Moreover, the abrasive | polishing material isolate | separated from the dropping means 500 falls in 2nd range R2 in principle. Even if the abrasive separated from the dropping means 500 jumps to the other (in the direction of D2), it falls only in the second range R2 by coming into contact with one of the standing walls 522. Therefore, it is possible to separate the abrasive separated from the separation discharge cylinder 30a and the abrasive separated from the dropping means 500. A first collection path 5201A that collects the abrasive that falls in the first range R1 and a second collection path 5202A (described later) that falls in the second range R2 are provided.
Note that when almost all of the abrasive separated from the separation discharge cylinder 30a falls into the first range R1, and almost all of the abrasive separated from the dropping means 500 falls into the second range R2, The standing wall 522 may not be provided.

Similarly, as shown in FIG. 4, FIG. 7A, and FIG. 7B, the separation discharge cylinder 30a and the drop means 500 allow the cylinder body 30 to pass from the other side of the cylinder body 30 to the other (direction D2) over a predetermined range RB. In the meantime, the abrasive is separated and falls.
The other standing wall 522 is provided at a position away from the other side of the cylindrical body 30 by a predetermined length in the direction away from the cylindrical body 30 (direction D2). The dropping means 500 is connected to the leading end portion of the lead-out path 32 that passes through the upper opening of the other standing wall 522 and exits from the other standing wall 522 to the outside (direction D2 side).

  Due to the other standing wall 522, the predetermined range RB further extends from the first range R1 between the other side of the cylindrical body 30 to a position separated by a predetermined length in the other direction (D2), and the first range R1. It is partitioned into a second range R2 up to a predetermined range RB separated to the other side. In principle, the abrasive separated from the separation discharge cylinder 30a falls into the first range R1. Even if the abrasive material separated from the separation / discharge cylinder 30a jumps to the other side (in the direction of D2), it comes into contact with the other standing wall 522 and falls only in the first range R1. Moreover, the abrasive | polishing material isolate | separated from the dropping means 500 falls in 2nd range R2 in principle. Even if the abrasive separated from the dropping means 500 jumps to one side (in the direction of D1), it falls only in the second range R2 by coming into contact with the other standing wall 522. Therefore, it is possible to separate the abrasive separated from the separation discharge cylinder 30a and the abrasive separated from the dropping means 500. A first collection path 5201B for collecting the abrasive that falls in the first range R1 and a second collection path 5202B (described later) for collecting the abrasive that falls in the second range R2 are provided. In addition, when almost all the abrasives separated from the separation discharge cylinder 30a fall into the first range R1, and almost all the abrasives separated from the dropping means 500 fall into the second range R2, the other The standing wall 522 may not be provided.

[Passage mechanism 523]
The abrasive G1 separated when passing through the first range R1 in the predetermined range RA is collected in the first collection path 5201A, and the abrasive G2 separated when passing through the second range R2 in the predetermined range RA is Collected in the second collection path 5202A. Here, it means that the first collection path 5201A has a function of collecting the abrasive G1, and the second collection path 5202A has a function of collecting the abrasive G2. Alternatively, not all of the abrasive material G1 can be collected due to a negative reason (unexpected scattering or spillage), and a part of the abrasive G1 may not be collected in the first collection path 5201A, or a part of the abrasive G2 may be collected. May not be collected in the second collection path 5202A.

  Similarly, the abrasive separated when passing through the first range R1 in the predetermined range RB is collected in the first collection path 5201B and separated when passing through the second range R2 in the predetermined range RB. Are collected in the second collection path 5202B.

  Since the abrasives G1 and G2 collected by the first collection path 5201A and the second collection path 5202A are sent to the funnel body 521 on the opposite side, in order to prevent clogging at the narrow portion, the abrasive G1, G2 is separately passed through the narrow part. Thereby, it can be directly sent to the funnel body 521 together with the abrasives collected by the first collection path 5201B and the second collection path 5202B.

  The passage mechanism 523 receives the abrasive G1 from the first collection path 5201A and the abrasive G2 from the second collection path 5202A from one side (D1 direction), and separately receives the other (D2 direction) side. Send to. A funnel body 521 is provided on the other side. The passage mechanism 523 includes an upper passage 5231 disposed in the upper stage and a lower passage 5232 disposed in the lower stage.

(First collection path 5201A, upper passage 5231)
FIG. 7A is a conceptual plan view of the first collection path 5201A and the upper passage 5231 as viewed from above.
As shown in FIGS. 4 and 7A, a first collection path 5201A is arranged below the first range R1 in the predetermined range RA so as to collect the abrasive that falls in the first range R1. . As shown by hatching in FIG. 7A, the first collection path 5201A is formed by a half circumferential wall 300A on one side (in the direction of D1) of the cylindrical body 30, one standing wall 522, a front standing wall 522, and a rear standing wall 522. It is an enclosed passage.

  As shown in FIGS. 4 and 5, the upper passage 5231 is disposed below the first collection path 5201A (this means that the upper passage 5231 is connected to the first collection path 5201A). ), And a slope inclined downward by a predetermined angle θ1 toward the other side (direction D2). The predetermined angle θ1 is an angle at which the abrasive flows down the slope by its own weight. The upper passage 5231 has a predetermined width W (for example, about 152 mm) wider than the outer diameter R (for example, about 100 mm) of the cylindrical body 30, includes the cylindrical body 30 in the passage, It is provided across from the (D1 direction) side to the other (D2 direction) side. The lower end portion of the upper passage 5231 communicates with the lower opening 522 b of the other standing wall 522. In the upper passage 5231, the narrowest portion having the narrowest road width when passing through the side of the cylindrical body 30 is formed. The width of the narrow portion is about 52 mm (W-R), and narrows to about 26 mm on one side.

  However, since only the abrasive G1 collected by the first collection path 5201A passes through the narrow portion in the upper passage 5231, it is possible to prevent clogging and stagnation of the abrasive G1 in the narrow portion. The abrasive G1 that has passed through the narrow portion flows down toward the lower end of the upper passage 5231 and falls from the lower end. As shown in FIGS. 4 and 5, a funnel body 521 is provided below the lower end portion of the upper passage 5231. As a result, the abrasive that has dropped from the lower end of the upper passage 5231 is collected in the funnel body 521.

(Second collection path 5202A, lower passage 5232)
FIG. 7B is a conceptual plan view of the second collection path 5202A and the lower passage 5232 as viewed from above. The second collection path 5202A is indicated by hatching in FIG. 7B.
As shown in FIGS. 4 and 7B, a second collection path 5202A is arranged below the second range R2 in the predetermined range RA so as to collect the abrasive that falls in the second range R2. . The second collection path 5202A is a passage having a slope inclined downward by a predetermined angle θ3 toward the other (direction D2). The predetermined angle θ3 is an angle at which the abrasive flows down the slope by its own weight. The lower end portion of the second collection path 5202A is passed through the lower inlet 522c of one standing wall 522.

The lower passage 5232 is connected to the lower end of the second collection passage 5202A, and has a slope inclined downward by a predetermined angle θ2 toward the other. The predetermined angle θ2 is an angle at which the abrasive flows down the slope by its own weight. The lower passage 5232 has a predetermined width W (> R) wider than the outer diameter R of the cylindrical body 30, includes the cylindrical body 30 in the passage, and the other side from one side (the direction of D 1) on both sides of the cylindrical body 30. It is provided across the (D2 direction) side. The lower end of the lower passage 5232 communicates with the lower opening 522 b of the other standing wall 522. In the lower passage 5232, the narrowest portion having the narrowest road width when passing the side of the cylindrical body 30 is formed. The road width of the narrow portion is (W−R) / 2 on one side.
However, since only the abrasive G2 collected by the second collection path 5202A passes through the narrow portion of the lower passage 5232, the clogging and staying of the abrasive G2 in the narrow portion can be prevented. The abrasive G2 that has passed through the narrow portion flows down toward the lower end of the lower passage 5232 and falls from the lower end. As shown in FIGS. 4 and 5, a funnel body 521 is disposed below the lower end portion of the lower passage 5232. Thereby, the abrasive that has dropped from the lower end of the lower passage 5232 is collected in the funnel body 521.

  The distance H in the height direction between the upper passage 5231 and the lower passage 5232 is such that the abrasive G2 passing through the narrow portion does not clog and stay in the narrow portion in the lower passage 5232. It is set according to the quantity. Furthermore, since the number of abrasives to be transported varies depending on the number of gaming machines arranged on the gaming machine island 1, the number of abrasives G2 passing through the narrow portion also varies. Therefore, at least one of the upper passage 5231 and the lower passage 5232 may be provided so as to be height-adjustable according to the quantity of the abrasive to be transported.

  As described above, the abrasives G1 and G2 collected by the first collection path 5201A and the second collection path 5202A separately pass through the narrow portion and are collected by the funnel body 521.

[Means for recovering the separated abrasive when passing through the predetermined range RB]
Next, with reference to FIGS. 4, 5, 7A, and 5C, a means for recovering the separated abrasive when passing through the predetermined range RB provided on the opposite side of the predetermined range RA with the cylindrical body 30 as the center. This will be described with reference to 7B.
As described above, the abrasive separated when it passes through the predetermined range RB is collected by the first collection path 5201B and the second collection path 5202B, and does not pass through the narrow portion, and enters the funnel body 521. Sent directly.

(First collection path 5201B, second collection path 5202B)
As shown in FIGS. 4 and 7A, a first collection path 5201B is arranged below the first range R1 in the predetermined range RB so as to collect the abrasive that falls in the first range R1. . As shown by hatching in FIG. 7A, the first collection path 5201B is formed by a half peripheral wall 300B on the other side (direction D2) of the cylindrical body 30, the other standing wall 522, the front standing wall 522, and the rear standing wall 522. It is an enclosed passage.

  As shown in FIGS. 4 and 5, the upper passage 5231 is disposed below the first collection path 5201B. The abrasive collected by the first collection path 5201B falls to a region downstream of the narrow portion in the upper passage 5231, flows down along the slope of the upper passage 5231, and falls from the lower end. The abrasive that has fallen from the lower end of the upper passage 5231 is collected by the funnel body 521.

  In some cases, the abrasive that has fallen into the downstream region and the abrasive G1 merge to increase the quantity thereof. However, the increased amount of the abrasive does not pass through the narrow portion, but falls as it is from the lower end portion of the upper passage 5231 and is collected in the funnel body 521. Therefore, the abrasive is clogged in the narrow portion. And no stagnation occurs.

As shown in FIGS. 4 and 7B, a second collection path 5202B is arranged below the second range R2 in the predetermined range RB so as to collect the abrasive that falls in the second range R2. . The second collection path 5202B is a passage having a slope inclined downward by a predetermined angle θ4 toward one side (direction D1). The predetermined angle θ4 is an angle at which the abrasive flows down the slope by its own weight. As shown in FIGS. 4 and 5, the lower end portion of the second collection path 5202 </ b> B is passed through the lower opening 522 b of the other standing wall 522. The lower end portion of the second collection path 5202B is disposed above the lower end portion of the upper passage 5231. That is, in order from the top, the lower end of the second collection path 5202B, the lower end of the upper passage 5231, and the lower end of the lower passage 5232 are arranged.
A funnel body 521 is disposed below the lower end of the second collection path 5202B (lower end of the upper passage 5231 and further below the lower end of the lower passage 5232). The abrasive collected by the second collection path 5202B flows down along the slope of the second collection path 5202B and falls from the lower end. The abrasive that has dropped from the lower end of the second collection path 5202B is collected by the funnel body 521.

  As described above, the abrasive that is separated when passing through the predetermined range RB, and the abrasive collected by the first collection path 5201B passes through the narrow portion even when it may join the abrasive G1. Instead, it is sent to the funnel body 521. Further, the abrasives separated when passing through the predetermined range RB and collected by the second collection path 5202B are directly sent to the funnel body 521 without joining the abrasives G1 and G2. . Therefore, these abrasives are sent to the funnel body 521 without hindrance.

  As described above, the funnel body 521 has an opening upward. The openings are provided at positions on the other side of both sides of the cylinder that can receive the abrasive that falls from the lower ends of the upper passage 5231, the lower passage 5232, and the second collection passage 5202B. The lower part of the funnel body 521 is configured such that the upper part of the abrasive stock 54 communicates with the inside of each other. The funnel 521 guides the abrasive to the top of the abrasive stock 54.

[Other separation means]
[Additional separation means 50b]
The game medium lifted by the transfer means 40 and the abrasive are separated by the separation means 50a described above, but an additional separation means 50b is provided to further increase the reliability of separation.
Next, the additional separation means 50b will be described.
FIG. 8 is a front view showing the additional separating means 50b. FIG. 9 is a plan view showing the separating means 50b. The separation means 50b aligns the game media from the separation means 50a in one step, and separates the abrasive from the aligned game media. Separating means 50 b includes aligning means 51 and dropping means 52.

(Alignment means 51)
The aligning means 51 aligns the game media from the separating means 50a in one step. The state in which the game media are lined up is a state in which the game media do not overlap in the height direction. In the present specification, a state in which game media do not overlap in the height direction is referred to as “one stage”. A state in which game media overlap in the height direction is referred to as “multiple stages”.

  The aligning means 51 includes a plurality of inclined surfaces 510. The plurality of inclined surfaces 510 allow the game medium to flow down while turning back. The plurality of inclined surfaces 510 are alternately inclined with respect to the adjacent inclined surfaces 510. The first inclined surface 510a receives the game medium on the upstream side of the inclination, causes the game medium to flow downstream along the inclination, and drops the game medium from the lower end. The second inclined surface 510b is provided to be inclined to the opposite side to the first inclined surface 510a. The second inclined surface 510b is provided at a position to receive a game medium dropped from the lower end of the first inclined surface 510a on the upstream side. The second inclined surface 510b causes the received game medium to flow along the inclination in a direction that turns back with respect to the inclination of the first inclined surface 510a, and drops the game medium from the lower end. The third inclined surface 510c is provided to be inclined to the opposite side to the second inclined surface 510b. The third inclined surface 510c is provided at a position to receive a game medium dropped from the lower end of the second inclined surface 510b on the upstream side. The third inclined surface 510 c causes the received game medium to flow down along the inclination in a direction that turns back with respect to the inclination of the second inclined surface 510 b, and guides the game medium to the dropping means 52. By providing the plurality of inclined surfaces 510 with such a structure, it is possible to increase the distance that the game medium flows down in a limited space. The longer the flow-down distance of the game media, the lower the overlap and the more the game media are aligned. The aligned game media are guided to the dropping means 52.

  One or more inclined surfaces 510 among the plurality of inclined surfaces 510 have a notch 511 on the downstream side in the direction in which the game medium flows (see FIG. 9). In FIG. 9, for the sake of explanation, the first inclined surface 510a is omitted, and the second inclined surface 510b, the third inclined surface 510c, and the dropping means 52 are shown. The second inclined surface 510b, the third inclined surface 510c, and the dropping means 52 are provided in this order from the front side to the back side of the sheet. In the second inclined surface 510b, the right side of the paper surface corresponds to the upstream side, and the left side of the paper surface corresponds to the downstream side. In the third inclined surface 510c and the dropping means 52, the left side of the paper surface corresponds to the upstream side, and the right side of the paper surface corresponds to the downstream side. By providing such a notch 511, the ball pressure of the game media is dispersed and the ball collapses, and the overlap between the game media is easily reduced. Thereby, the game media are further easily aligned.

  Among the plurality of inclined surfaces 510, the inclined surface 510 on the downstream side in the direction in which the game medium flows is arranged so that the gradient is steeper than the gradient of the other inclined surfaces 510. Since the downstream slope is steep, the ball pressure from the upstream game medium is reduced as the game medium approaches the dropping means 52. Thereby, the game media are further easily aligned. A similar notch 511 may be provided on the downstream side of the first inclined surface 510a.

(Drop means 52)
The dropping means 52 separates the abrasive from the game medium by dropping the abrasive and the dirt component from the game media aligned by the aligning means 51. The dropping unit 52 drops the abrasive and the dirt component that are not separated by the dropping unit 500.

  Similar to the dropping means 500, the dropping means 52 includes a plurality of rails. The plurality of rails are arranged with a gap having a predetermined width. A plurality of rails allow game media to flow over them and drop the abrasive through the gaps. The game medium that has passed through the dropping means 52 is guided to the island top 9. The dropped abrasive is guided to the collection tube 530. For example, when the game media flow on the rails in a state where they overlap in a plurality of stages, the abrasive separated in the upper stage may adhere to the lower stage game media. However, the certainty of separation between the game medium and the abrasive is improved by aligning the game media in one step and passing the game media over the rail.

(Recovery tube 530)
The upper end of the recovery pipe 530 is provided below the dropping means 52. The collection tube 530 is provided at a position where it can receive the abrasive that falls from the dropping means 52. The lower end of the collection pipe 530 is communicated with the upper part of the abrasive stock 54. The recovery pipe 530 allows the abrasive to flow down through the inside thereof. The collection tube 530 guides the abrasive to the top of the abrasive stock 54. The lower part of the recovery pipe 530 and the upper part of the abrasive stock 54 are communicated with each other.

(Return passage 60)
The return passage 60 is connected to the lower part of the abrasive stock 54 from a position communicating with the recovery pipe 530.

(Dust collecting means 62)
The dust collecting means 62 collects dirt components. The dust collecting means 62 includes a first dust collecting path 56a, a second dust collecting path 56b, and one dust collecting device 57 (see FIG. 2).

(First dust collection path 56a)
The first dust collection path 56 a is a path for collecting dirt components from the abrasive material stock 54. The first dust collection path 56 a is connected to the abrasive stock 54. The first dust collection path 56 a includes a dust collection nozzle 56 and a first dust collection hose 551. The dust collection nozzle 56 is attached so as to protrude into the abrasive stock 54 from a hole provided in the wall of the abrasive stock 54. The dust collection nozzle 56 has a clearance enough to allow dirt components to pass therethrough and not allow abrasives to pass through.

  The proximal end of the dust collection nozzle 56 is connected to the first dust collection hose 551 (see FIG. 8). Further, the first dust collecting hose 551 is connected to the dust collecting device 57. Thereby, the dust collector 57 sucks the dirt component together with the air in the abrasive stock 54 through the dust collection nozzle 56 and the first dust collection hose 551.

  The abrasive that has fallen without being sucked into the dust collection nozzle 56 is stored in the abrasive stock 54. The lower part of the abrasive stock 54 and the upper part of the return passage 60 are configured to communicate with each other. The abrasive stored in the abrasive stock 54 flows out to the return passage 60. The abrasive that has flowed down flows down the return passage 60 and is guided to the junction 31.

(Second dust collection path 56b)
The second dust collection path 56 b is a path for collecting dirt components from the return path 60. The second dust collection path 56 b is used to collect the dirt component that has not been sucked into the dust collection nozzle 56 in the abrasive material stock 54 and the dirt component that has flowed down through the recovery pipe 530. The second dust collection path 56 b is connected to the return path 60. The second dust collection path 56 b includes a dust collection port 61 and a second dust collection hose 552. The dust collection port 61 is provided at the bottom of the return passage 60. The dust collection port 61 has a gap that allows dirt components to pass therethrough and prevents the abrasive from passing (see FIG. 3). As a result, the abrasive is not sucked into the dust collection port 61 and is guided to the merging portion 31.

(Dust collector 57)
The dust collecting means 62 includes one dust collecting device 57. Further, the first dust collecting hose 551 and the second dust collecting hose 552 are connected to one dust collecting device 57. The dust collector 57 has power capable of sucking air. The dust collector 57 collects the dirt component via the first dust collection path 56a and collects the dirt component via the second dust collection path 56b. With this configuration, the dust collector 57 collects dirt components through both the first dust collection path 56a and the second dust collection path 56b. Therefore, space saving can be achieved. Further, by collecting the dirt component using the two dust collection paths, the certainty of the separation between the abrasive and the dirt component is improved.

<Second Embodiment>
Next, the passage mechanism 523 according to the second embodiment will be described with reference to FIGS. 10A and 10B. FIG. 10A is a front view of the main part of the passage mechanism, conceptually showing the gate member moved to the first position, and FIG. 10B conceptually showing the gate member moved to the second position. FIG.

  The passage mechanism 523 of the first embodiment spatially separates the abrasive G1 collected by the first collection path 5201A and the abrasive G2 collected by the second collection path 5202A into narrow portions. Configured to pass.

  On the other hand, the passage mechanism 523 of the second embodiment has a gate member 5233 and a gate driving means (not shown), and the abrasive G1 and the abrasive G2 pass through the narrow portion separately in time. Configured to let The second embodiment is different from the first embodiment in that the upper passage 5231 is not provided, but the lower passage 5232 is connected to the second collection passage 5202A in the first embodiment. It is the same.

  The gate member 5233 opens the first collection path 5201A, and closes the second collection path 5202A. The gate member 5233 closes the first collection path 5201A while opening the second collection path 5202A. It is pivotally supported by the upper edge part of the lower inflow port 522c of one standing wall 522 so that rotation to a position is possible. Further, the intermediate portion 5234 of the gate member 5233 is pivotally supported. One end portion 5235 of the gate member 5233 is formed along the half circumferential wall 300A of the cylindrical body 30 when the gate member 5233 is rotated to the second position. Further, one end portion 5235 of the gate member 5233 is formed along the front standing wall 522 and the rear standing wall 522. One end portion 5235 of the gate member 5233 has a tip bent upward. The other end 5236 of the gate member 5233 is formed so as to close the lower inlet 522c when the gate member 5233 is rotated to the first position.

  The gate member 5233 is driven between the first position and the second position by the gate driving means. The timing for driving the gate member 5233 may be a predetermined time interval. The abrasive G1 collected by the first collection path 5201A and the abrasive G2 collected by the second collection path 5202A May be detected by a detection means (not shown) and driven based on the detection result.

<Third Embodiment>
Next, a passage mechanism 523 according to a third embodiment will be described with reference to FIG. FIG. 11 is a front view of an essential part of the passage mechanism.
In the first embodiment, the lower end of the upper passage 5231 is disposed above the funnel body 521.
On the other hand, in the third embodiment, the lower end portion of the upper passage 5231 is disposed at the position of the narrow portion.
The reason for this arrangement is that the abrasive G1 collected by the first collection path 5201A is guided to the narrow part in the upper passage 5231 and then the abrasive G2 collected by the second collection path 5202A Since the abrasive G2 also passes through the narrow portion in the lower passage 5232 even if they merge in the lower passage 5232, the abrasives G1 and G2 are not clogged and retained in the narrow portion. is there.

<Fourth Embodiment>
Next, the separating means 50a according to the fourth embodiment will be described.
In the first embodiment, the separation unit 50 a includes a separation discharge cylinder 30 a and a dropping unit 500.

  On the other hand, in the fourth embodiment, the dropping means 500 is provided without the separation discharge cylinder 30a. The dropping means 500 according to the fourth embodiment is provided over a predetermined range RA in a direction away from the cylindrical body 30 from both sides of the cylindrical body 30, and is arranged in the front-rear direction at intervals that allow the abrasive to pass through. It has a plurality of rails that flow down along it, and has two or more scissors-like passages extending in a direction away from the cylinder 30.

A first collection path 5201A is arranged in the first range R1 of the dropping means 500, and a second collection path 5202A is arranged in the second range R2 of the dropping means 500. Note that the upper passage 5231 is connected to the first collection path 5201A, and the lower passage 5232 is connected to the second collection path 5202A, as in the first embodiment.
For example, the first range R1 and the second range R2 are divided as follows.
The first range R <b> 1 is a range in which the limiting unit 501 is provided in the dropping unit 500. The second range R2 is a range in which the limiting unit 501 is not provided.

  As described above, the sheet material constituting the limiting unit 501 has a function of scoring the abrasive from the game medium. Therefore, in the first range R1 that is relatively close to the cylindrical body 30, the abrasive that has been scraped by the sheet material is collected by the first collection path 5201A, and in the second range R2 that is relatively far from the cylindrical body 30, The dropped abrasive is collected by the second collection path 5202A.

<Fifth Embodiment>
Next, a collection path according to the fifth embodiment will be described.
In the first embodiment, the abrasive separated by the additional separating means 50 b is guided to the abrasive stock 54 through the inside of the collection tube 530. One of the reasons for using the collection pipe 530 and not using the collection path such as the first collection path 5201A or the second collection path 5202A is that the position of the separating means 50b is almost the same as the position of the funnel body 521. This is because an inclination angle for allowing the abrasive from the separating means 50b to flow down by its own weight cannot be obtained.

  On the other hand, in the fifth embodiment, the position of the separating means 50b is arranged higher than the position of the funnel body 521 so that an inclination angle for allowing the abrasive from the separating means 50b to flow down by its own weight is obtained. And a third collection path for guiding the abrasive flowing down from the separating means 50b to the funnel body 521.

<Modification>
In the above-described embodiment, the first collection path 5201A is connected to the upper passage 5231 and the second collection path 5202A is connected to the lower passage 5232, but the reverse mode may be used. That is, the first collection path 5201A is connected to the lower path 5232, and the second collection path 5202A is connected to the upper path 5231. At this time, the separation / discharge cylinder 30 a is lower than the position shown in the first embodiment, and is provided in a region between the upper passage 5231 and the lower passage 5232.

  In the embodiment, the angles of the inclined surfaces of the upper passage 5231, the lower passage 5232, and the second collection passages 5202A and 5202B are θ1, θ2, θ3, and θ4. These angles may be the same or different. For example, in the upper part of the lift polishing apparatus 10, the second collection path 5202A and the lower path 5232 connected obliquely downward toward the other (in the direction of D2) are lifted and polished when their angles θ2 and θ3 are increased. There is a possibility that the overall height of the device 10 is increased, which is contrary to the miniaturization of the device. Therefore, the angles θ1 and θ4 of the upper passage 5231 and the second collection passage 5202B, which are unlikely to increase the overall height, may be increased to improve the flow of the abrasive.

  Although the embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
