Is done. The transferred game balls and abrasives flow out from the upper end of the cylindrical body 30 to the separating means.

  The height from the cylinder axis of the lower end portion (linear cylinder 320A) of the cylindrical body 30 to the upper edge of the waist plate 104 is hereinafter referred to as “waist plate height H”. The height of the gaming machine 200 placed on the board 103 is substantially constant between the gaming machine islands 1. Since the height of the base plate 103 is also the height of the upper edge of the waist plate 104, the height H of the waist plate 104 is substantially constant between the gaming machine islands 1. In the following description, the height H of the waist plate 104 is constant. Further, the height from the waist plate 104 to the island tank 3 is made constant.

The length LA from the position of the cylinder axis (position in the X direction) of the upper cylinder 310 to the position RP differs depending on the gaming machine island 1. The lower cylinder 320 has a length LB, which is a distance (full length) along the cylinder axis between both ends, corresponding to the length LA (gaming machine island 1). That is, the lift polishing apparatus 10 according to the present embodiment prepares a plurality of types of lower cylinders 320 having different lengths LB, so that the position of the lower cylinder 320 at the position RP is changed even if the position RP that receives the game medium changes. Since the position of the merging portion 31 can be matched, a plurality of types of lengths LA can be handled. Here, the “type” is determined according to the length and the bending radius R (described later), and is not determined according to other elements such as the material.

<Preparation stage>
In the preparation stage shown in step S101 of FIG. 4, an upper cylinder 310 having the same length and a plurality of types of lower cylinders 320 having different lengths LB are prepared.
The preparation of the lower cylinder 320 will be described with reference to FIG.

Furthermore, the height H from the cylinder axis of the linear cylinder 320A to the upper edge of the waist plate 104 is shown. When a plurality of types of lower cylinders 320 having different lengths LA are prepared, the same receiving cylinder 321 is prepared. In the following description, the lengths L1, L3, and L4 are assumed to be constant. Further, description will be made assuming that the height H is constant.

As shown in FIG. 3, the relationship between the length LA from the position of the cylinder axis (position in the X direction) to the position RP of the upper cylinder 310 and the length LB of the lower cylinder 320 is expressed by the following equation (1) expressed.
LB = L4 + LA + πR / 2 + H-2R (1)

(2) A plurality of types of curved tubes 330 having different bending radii R are prepared (hereinafter referred to as second preparation). Further, (3) a plurality of types of lower cylinders 320 having different ratios between the length L and the bending radius R of the linear cylinder 320A are prepared (hereinafter referred to as third preparation).

The length L is expressed by the following formula (3).
L = L1 + L2 (3)
The ratio between the length L and the bending radius R is expressed by the following formula (4).
L / R = (L1 + L2) / R (4)

Next, the first preparation to the third preparation will be described.
(First preparation)
A receiving cylinder 321 having the same length L1 is prepared. The length L1 is preferably about 41 cm which is shorter. The short receiving cylinder 321 has the following advantages.
The length L1 of the receiving cylinder 321 is determined by a front opening (described above) that receives a game ball or the like. That is, by preparing a short receiving cylinder 321 while securing a necessary width, the length L3 of the position RP from the right end is also shortened, and the length L3 and the length L2 of the relay cylinder 322 The length LA which is the sum of the bending radius R of the curved tube 330 is also shortened. In particular, when the relay cylinder 322 is not used (L2 = 0 mm), the length LA is the shortest. The lower cylinder 320 can also be applied to the gaming machine island 1 having a shorter length LA.

Further, a plurality of types of relay cylinders 322 having different lengths L2 are prepared. The length L2 is preferably about 480 mm or less because the number of combinations with the bending radius R of the curved tube 330 increases.
Further, a curved tube 330 having the same bending radius R is prepared.
Further, an upper cylinder 310 having the same length is prepared.

Next, an example of the first preparation will be described. It is assumed that the length L1 = 407 mm, the length L3 = 150 mm, and the bending radius R = 250 mm.
The length L2 (= 0 mm, 120 mm, 240 mm, 360 mm, 480 mm), the length L3 (= 150 mm), and the bending radius R (= 250 mm) are substituted into the above equation (2).

The length LA is 640 mm (= 240 mm + 150 mm + 250 mm).
The length LA is 760 mm (= 360 mm + 150 mm + 250 mm).
The length LA is 880 mm (= 480 mm + 150 mm + 250 mm).

The bending radius R is preferably about 250 mm or more in terms of the bending condition of the screw member 41 inserted into the cylinder 30 or the molding of the cylinder 30 itself, and further, the length of the relay cylinder 322 is long. Since there are many combinations with the length L2, it is preferably about 250 mm. The bending radius R is preferably equal to or less than the height H of the waist plate 104 (R ≦ H). This is because the curved tube 330 is accommodated in a lower space (described above) below the height H of the waist plate 104. Moreover, it is for leaving the linear part (range of (HR) shown in FIG. 3) which is a part which connects the upper cylinder 310 and the lower cylinder 320. FIG.

The length L2 (= 0 mm), the length L3 (= 150 mm), and the bending radius R (= 250 mm, 370 mm, 490 mm, 610 mm, 730 mm) are substituted into the expression (2).

The assigned result is shown below.
The length LA is 400 mm (= 0 mm + 150 mm + 250 mm).
The length LA is 520 mm (= 0 mm + 150 mm + 370 mm).
The length LA is 640 mm (= 0 mm + 150 mm + 490 mm).
The length LA is 760 mm (= 0 mm + 150 mm + 610 mm).
The length LA is 880 mm (= 0 mm + 150 mm + 730 mm).
That is, by preparing five types of curved tubes 330 having different bending radii R, it is possible to cope with five types of lengths LA.

  The second preparation described above is an example, and the bending radius R of the curved tube 330 is not limited to these, and the length L2 of the relay tube 322 is not limited to 0 mm.

From the top of 330 molding, it is preferably from about 0.6 to about 3.5.
Further, an upper cylinder 310 having the same length is prepared.

Next, an example of the third preparation will be described. The length L1 = 407 mm and the length L3 = 150 mm are constant.
L / R = (L1 + L2) / R (4)
The length L2 (= 0 mm, 110 mm, 220 mm, 350 mm, 480 mm) and the bending radius R (= 250 mm, 260 mm, 270 mm, 260 mm, 250 mm) are substituted into the above equation (4).

The assigned result is shown below.
The length LA is 400 mm (= 0 mm + 150 mm + 250 mm).
At this time, L / R is about 1.6 (= (407 mm + 0 mm) / 250 mm).
The length LA is 520 mm (= 110 mm + 150 mm + 260 mm).
At this time, L / R is about 1.9 (= (407 mm + 110 mm) / 260 mm).
The length LA is 640 mm (= 220 mm + 150 mm + 270 mm).
At this time, L / R is about 2.3 (= (407 mm + 220 mm) / 270 mm).
The length LA is 760 mm (= 350 mm + 150 mm + 260 mm).
At this time, L / R is about 2.9 (= (407 mm + 350 mm) / 260 mm).
The length LA is 880 mm (= 480 mm + 150 mm + 250 mm).
At this time, L / R is about 3.5 (= (407 mm + 480 mm) / 250 mm).
That is, by preparing a combination of five types of L / R relay cylinders 322 and curved cylinders 330, it is possible to cope with five types of lengths LA.

Note that LA = 880 mm may be a combination of the next relay cylinder 322 and the curved cylinder 330.
L2 = 0mm, L3 = 150mm, R = 730mm

The length of the lower spiral body 412 in the spiral axis direction corresponds to the length LB of the lower cylinder 320 (the length LA from the position of the cylinder axis (position in the X direction) of the upper cylinder 310 to the position RP). That is, for the upper spiral body 411, an upper spiral body 411 having the same length is prepared. On the other hand, regarding the lower spiral body 412, a plurality of types of lower spiral bodies 412 having different lengths are prepared.

(Upper spiral body 411)
FIG. 7A is a front view of the upper spiral body 411, FIG. 7B is a side view of the upper spiral body 411, and FIG. 7C is a view taken in the direction of arrow C when the upper spiral body 411 is viewed in the direction along the spiral axis. As shown in FIGS. 7A to 7C, the upper spiral body 411 is formed by winding a thick wire having a width of about 13 mm and a thickness of about 6 mm in a spiral shape having a large diameter (outer diameter: about 65 mm, inner diameter: about 39 mm). A shaft body 43 is fitted to the inner diameter portion of the upper end portion of the upper spiral body 411. The winding pitch of the upper spiral body 411 is 50 mm.

(Lower spiral 412)
FIG. 8A is a front view of the lower spiral body 412, and FIG. 8B is an arrow view when viewed in a direction along the spiral axis of the lower spiral body 412. As shown in FIGS. 8A and 8B, the lower spiral body 412 is formed by winding a thin wire having a width of about 10 mm and a thickness of about 4 mm in a spiral shape having a small diameter (outer diameter: about 58 mm, inner diameter: about 38 mm). The winding pitch of the lower spiral body 412 is 40 mm. The winding direction of the wire is the same in both the upper spiral body 411 and the lower spiral body 412.

(Connection of upper spiral 411 and lower spiral 412)
The upper spiral body 411 and the lower spiral body 412 are connected as follows.
First, the upper spiral body 411 used in common between the gaming machine islands 1 is prepared. Subsequently, a lower spiral body 412 of a type having a length corresponding to the length LB (or length LA) of the lower cylinder 320 is prepared.

  Next, the ends of the upper spiral body 411 and the lower spiral body 412 are connected to each other. 9A is a front view showing a state in which the ends of the upper spiral body and the lower spiral body are overlapped with each other, FIG. 9B is a sectional view taken along the line VII-VII in FIG. 9A, and FIG. It is an enlarged front view which shows a state when edge parts of are overlapped.

  As shown in FIGS. 9A, 9B and 10, the lower end of the upper spiral 411 (left end in FIG. 9A, lower end in FIG. 10) and the upper end of the lower spiral 412 (right end in FIG. 9A, upper end in FIG. 10) are aligned. At this time, the upper end of the lower spiral 412 rides on the lower end of the upper spiral 411. Next, the upper spiral body 411 and the lower spiral body 412 are rotated around the spiral axis in opposite directions so that the lower end portion 411A of the upper spiral body 411 and the upper end portion 412A of the lower spiral body 412 are overlapped by one turn.

  Since the winding pitches of the upper spiral body 411 and the lower spiral body 412 are different from each other, the lower end portion 411A and the upper end portion 412A are actually overlapped in one turn as shown in FIG. 9B and FIG. Become part of it.

FIG. 11 is an enlarged front view of the ends of the upper and lower spirals connected to each other.
Next, for example, using a clamper, the lower end of the upper spiral body 411 and the upper end portion 412A of the lower spiral body 412 are sandwiched from above and below, and the upper end of the lower spiral body 412 and the lower end portion 411A of the upper spiral body 411 are sandwiched from above and below. As a result, as shown in FIG. 11, the winding pitch of the upper spiral body 411 is narrowed in one turn, while the winding pitch of the lower spiral body 412 is widened. As a result, the winding pitch P is the same. As a result, almost all of one volume is overlapped with each other. Then, two or more locations are welded together. The lower spiral of the upper spiral 411 is used as a welding point so that the lower end of the upper spiral 411 is not separated from the upper end 412A of the lower spiral 412 and the upper end of the lower spiral 412 is not separated from the lower end 411A of the upper spiral 411. It is preferable to include two locations, the position and the position of the upper end of the lower spiral body 412.

(Assembly of screw member 41)
As described above, the ends of the upper spiral body 411 and the lower spiral body 412 are connected to each other. Next, assembly of the screw member 41 will be described.

  The screw member 41 is inserted into the cylindrical body 30 from the upper end opening of the cylindrical body 30 with the lower spiral body 412 first. The lower spiral body 412 passes through the upper cylinder 310, passes through the curved cylinder 330 of the lower cylinder 320, passes through the relay cylinder 322 of the lower cylinder 320, and reaches the receiving position RP of the game medium in the receiving cylinder 321. Accordingly, the upper spiral body 411 is inserted into the upper cylinder 310, and the lower spiral body 412 is inserted into the lower cylinder 320. At this time, the mutually connected ends of the upper spiral body 411 and the lower spiral body 412 are arranged in a straight line portion of the curved cylinder 330 (a range indicated by (HR) in FIG. 3) in the lower cylinder 320. Like that.

Next, the shaft body 43 in the upper spiral body 411 is attached to the motor 42. Thereby, the screw member 41 turns in the cylindrical body 30 by the rotation of the motor 42. Thus, the assembly of the screw member 41 is completed.
The reason why the thin wire rod is used for the lower spiral body 412 is that, for example, the lower spiral body 412 is easily bent in the curved tube 330 having a bending radius R of about 250 mm.

  The inner diameter of the upper cylinder 310 and the lower cylinder 320 is about 94 mm. Accordingly, the gap between the inner wall of the upper cylinder 310 and the outer diameter of the upper spiral body 411 is about 14.5 mm (= (94 mm−65 mm) / 2). Further, the gap between the inner diameter of the lower cylinder 320 and the outer diameter of the lower spiral body 412 is about 18 mm (= (94 mm−58 mm) / 2). The clearance (about 18 mm) in the lower spiral 412 is wider than the clearance (approximately 14.5 mm) in the upper spiral 411, but the lower spiral 412 transfers game media and the like in the straight cylinder 320 </ b> A and the curved cylinder 330. Therefore, game media and the like can be transported without problems.

  In the embodiment described above, the height H from the cylinder axis of the linear cylinder 320A to the upper edge of the waist plate 104 is described as being constant, but the present invention is not limited to this. Depending on the gaming machine island 1, the height H changes. When the height H changes, for example, it can be dealt with by changing the length of the straight portion of the curved tube 330 (indicated by (HR) in FIG. 3).

  In the embodiment, a game ball has been described as an example of a game medium. However, an object to be polished with an abrasive is not limited to this, and a medal used in a slot machine may be used.
